Description

  The present invention relates to a method for providing maintenance and management services for airport facilities, a method for executing processing necessary for maintenance and management of airport facilities, and a computer system. It relates to airport facility maintenance services for the purpose of improving safety.

  Traditionally, airport facilities such as runways, landing zones, and aprons have been maintained throughout the year so that aircraft can be operated safely and smoothly.

Such airport facility maintenance costs are a major burden at each airport. For example, in the case of Tokyo International Airport (Haneda Airport), the area to be mowing is 3.2 million m ² , the number of mowing is 3 to 4 times a year, and the unit price per 1 m ² is 50 yen. The annual cost is estimated to be 640 million yen (= 50 yen / m ² × 3.2 million m ² × 4 times).

  In fact, at Tokyo International Airport, 661.35 million yen was paid for maintenance work in fiscal 2011, and the total number of people involved in maintenance work reached approximately 11200 annually. . Of particular note is that the number of mowing workers is estimated to be 5390 per year, and labor costs alone are estimated at around 200 million yen.

  This mowing operation is specifically performed in an area where plants such as grass and grass grow, such as a landing zone that plays an important role in aircraft operation.

  The landing zone is a vast area that extends around the runway to ensure safety when the aircraft is landing. In Article 2 of the Aviation Law, a landing zone is provided for use in "takeoff of an aircraft in a specific direction (including the following, including water)" or landing (including the same, including landing). It is defined as the rectangular part in the airfield. In the Aviation Law Enforcement Regulations, the standard value corresponding to the length and width of the runway is shown as the width of the landing zone.

  This landing zone plays an important role in mitigating shock to the aircraft by plants such as turf and grass and minimizing damage when the aircraft deviates from the runway. Further, since the landing zone appears as a green zone to the pilot in the sky, the pilot can easily identify the runway by the contrast between the landing zone, which is a green zone, and the asphalt runway. In addition, signs such as guide lights that guide the landing of the aircraft are also installed in the landing zone.

  In the landing zone of this role, if plants such as turf and grass are too short, the cushioning when the airplane fails to land will be impaired, and conversely the plants such as turf and grass in the landing zone will grow too much Because it is difficult to see signs such as guide lights, and it is difficult to get ambulances and fire trucks into the landing zone in an emergency, so at Tokyo International Airport, plants such as grass and grass in the landing zone are It is obliged to cut to 5cm.

  Currently, the mowing work of cutting plants such as grass and grass in the landing zone is performed manually or by manipulating a tractor. The use of such a tractor for mowing work is disclosed in Patent Document 1, for example. When mowing during the day, the operator must evacuate the tractor every time the aircraft takes off and landing, and the work efficiency is poor. Therefore, the work is usually performed at night. Therefore, enormous labor costs are incurred for mowing the landing zone.

  Furthermore, in addition to the labor costs for the mowing work of the landing zone, work vehicles for mowing such as tractors are kept at each airport, so the purchase cost and maintenance cost of the work vehicles are enormous. It has become.

  In addition, at the airport, there is a problem of bird strike that hinders safe and smooth operation of the aircraft. At present, when a group of three people patrol the airport and see a bird, We are taking measures against bird damage by emitting a loud sound to drive away birds.

  Furthermore, at airports, in addition to the problem of costly cutting of the landing zone and measures against bird damage, it is important for the safe operation of the aircraft that the wintering of plants such as grass and grass in the landing zone will lead to aircraft landing failure. There's a problem. Here, the wintering of plants such as turf and grass in the landing zone leads to the failure of the aircraft to land when the wintering of plants such as turf and grass in the landing zone occurs and the contrast between the runway and the landing zone decreases. This is because it becomes difficult for the pilot to identify the runway. In fact, at airports that have taxiways parallel to the runway, it is difficult to distinguish the runway from the taxiway due to the wintering of plants such as turf and grass in the landing zone. Accidents such as getting off have also occurred. Here, the taxiway is a passage for the aircraft to move from an apron or the like to take a predetermined position on the runway for takeoff or to move from the runway to an apron or the like after landing. Is a place where aircraft are parked for passengers getting on and off, loading and unloading cargo, refueling, simple inspection and maintenance.

(Embodiment 1)
The present invention relates to a method and system for providing a maintenance service for an airport facility including at least one region where plants such as grass and grass grow. The airport includes facilities such as landing zones, taxiways, and aprons that play an important role in the safe and smooth operation of aircraft. The landing zone is a vast area where plants such as grass and grass grow, and is around the runway. It has spread. The plant can be grass or grass, but is not limited thereto. The plant can be any plant.

  First, one form of providing an airport facility maintenance management service will be described.

(Forms that provide airport facility maintenance management services)
FIG. 1A shows a plurality of airports A1 to A5 that one office 1000 that provides an airport facility maintenance management service is responsible for.

  The plurality of airports handled by one office 1000 are preferably neighboring airports, but are not limited thereto. Here, the establishment 1000 is responsible for, for example, three airports A1 to A3 in the Kansai region and two airports A4 to A5 in the Kanto region, for example, and for each of these five airports A1 to A5, A facility maintenance service S is provided. As a result, each airport can maintain and manage the airport facility by the airport maintenance service provided by the business office 1000, even if it does not have machinery and know-how for maintaining the airport facility. is there. In addition, the airports that one office 1000 serves are not limited to, for example, airports in the Kansai and Kanto regions, but are located in domestic airports such as the Tohoku, Chugoku, and Kyushu regions, or in the vicinity of the country where the office 1000 is located. It may be a foreign airport located.

  FIG. 1B shows a state in which the five airports A1 to A5 that the office 1000 serves are divided into two groups in order to improve the efficiency of maintenance work.

  In the example shown in FIG. 1B, airports A1 to A3 are classified into one group (unit U1), and airports A4 to A5 are classified into another group (unit U2). Airports belonging to the same group are preferably close to each other, but are not limited thereto. In the example shown in FIG. 1B, the runways of the airports A1 to A5 are indicated by bold lines.

  The business establishment 1000 provides an airport facility maintenance management service to the airports A1 to A5 in units of these groups (ie, units). For example, the business establishment 1000 provides one or more vehicles owned by the business establishment 1000 (or the company to which the business establishment 1000 belongs) to the airport A1. For example, one or more vehicles may be carried into the airport A1 by driving and moving one or more vehicles by an operator of the business establishment 1000. Alternatively, one or more vehicles may be carried into the airport A1 by transporting one or more vehicles on a truck by an operator of the business establishment 1000. One or more vehicles are vehicles (for example, mowers) used to maintain and manage airport facilities, and maintain and manage airport facilities (for example, areas where plants such as turf and grass grow in landing zones). Sensors that collect various data related to the growth of plants such as grass and grass that can be used in the field are installed. Here, the data related to the growth of plants such as turf and grass is at least the environmental data indicating the environment in which plants such as turf and grass grow and the growth state data indicating the growth state of plants such as turf and grass. Including one. One or more vehicles are preferably shared at several airports in each unit. For example, one or more vehicles may be shared by the airports A1 to A3 belonging to the unit U1, and another one or more vehicles may be shared by the airports A4 to A5 belonging to the unit U2. However, the form in which one or more vehicles for airport maintenance are shared in the airport facility is not limited to such a form. For example, one or more vehicles travel around the airports A1 to A3 belonging to the unit U1. After that, the same one or more vehicles may travel around the airports A4 to A5 belonging to the unit U2.

  While one or more vehicles carried into the airport A1 are used for maintenance of the airport A1, the one or more vehicles receive various data that can be used for maintenance of the airport A1 (for example, lawn and Data related to the growth of plants such as grass). Data collected by the one or more vehicles is stored in the maintenance management system 100 installed in the office 1000. The maintenance management system 100 generates information that can be used for maintenance of the airport A1 by processing the stored data. This information is provided to the airport A1 (for example, the manager of the airport A1).

  One or more vehicles carried into the airport A1 are moved to the airport A2 after one week, for example, and moved to the airport A3 after one week. As described above, one or more vehicles provided from the office 1000 can be shared between the airports A1 to A3 included in the unit U1 with the unit U1 as one unit. The work of moving one or more vehicles between airports is preferably handled by an operator of the business establishment 1000, but is not limited thereto. Of course, the shift for patrol of one or more vehicles need not be performed every week, and may be performed every predetermined period. At the same time that a set of one or more vehicles are brought into the airport A1, another set of one or more vehicles are brought into the airport A2, and these two sets of one or more vehicles are shared on a patrol basis. By doing so, it is also possible to reduce the work interval.

  Thus, since one or more vehicles carried into each airport are periodically provided from the office 1000, it is not necessary for each airport to own one or more vehicles. Therefore, it is not necessary for each airport to pay for the purchase or maintenance of one or more vehicles. Furthermore, since information that can be used for maintenance of each airport is provided from each business office 1000 to each airport, it is not necessary for each airport to have its own computer facilities. As a result, each airport can reduce the cost required for airport maintenance.

  In the example shown in FIG. 1A, one office 1000 serves five airports, but the number of airports served by one office 1000 is not limited to five. One office 1000 can serve any number of airports. Further, in the example shown in FIG. 1B, three airports are included in one unit U1, and two airports are included in the other unit U2, but airports included in one unit. Is not limited to three or two. A unit can include any number of airports.

  Furthermore, in the example shown in FIGS. 1A and 1B, a plurality of airports handled by one office are grouped to provide a maintenance service, but the present invention is not limited to this. For example, a maintenance service may be provided to an airport for each airport without grouping a plurality of airports handled by one office.

(Maintenance management system 100)
FIG. 2A shows an example of the configuration of the maintenance management system 100 installed in the business establishment 1000 shown in FIG. 1B.

  The maintenance management system 100 executes a process necessary for providing a maintenance management service. The maintenance management system 100 includes a computer system Cs and one or more vehicles V that can move on at least one area (landing zone). Here, the one or more vehicles may be a mower as described above, but may be a vehicle that does not have a function as a mower. One or more vehicles V are equipped with at least one sensor for detecting data related to the growth of plants such as grass and grass. The data related to the growth of plants such as turf and grass includes at least one of environmental data indicating the environment in which plants such as turf and grass grow, and growth state data indicating the growth state of plants such as turf and grass. The environmental data includes at least one of data indicating temperature, data indicating humidity, data indicating wind direction, data indicating soil moisture content, and data indicating soil pH value. The growth state data includes data indicating the concentration of chlorophyll. Here, the vehicle V has at least a moisture sensor that detects the moisture content of the soil, which is environmental data of a region where plants such as turf and grass grow, and the concentration of chlorophyll as the growth state of plants such as turf and grass. It is preferable that a chlorophyll sensor for detecting the data to be shown is mounted.

  FIG. 2B shows an example of the configuration of the computer system Cs included in the maintenance management system 100 shown in FIG. 2A.

  The computer system Cs, as well as knowledgeable and experienced workers, provides reference data indicating criteria for judging work necessary for maintenance of airport facilities from data related to the growth of plants such as grass and grass. A data processing unit that creates work information indicating work required for maintenance of the airport facility by referring to the reference data based on the stored database Db1 and the detected data related to the growth of plants such as grass and grass Dp. In the computer system Cs, the work information created by the data processing unit Dp is stored in a storage device (not shown).

  FIG. 2C shows an example of an airport that is the target of the maintenance service. In the example shown in FIG. 2C, the airport A1 has, as airport facilities, a first runway 1, a first landing zone 1a, a first apron 1b, and a first runway 1 provided so as to surround the first runway 1. The first taxiway 1c, the second runway 2, the second landing zone 2a provided so as to surround the second runway 2, the second apron 2b, the second runway 1 and the first apron 1b A second guiding path 2c that connects the two apron 2b is provided. The reference data is, for example, from the two parameters of soil moisture and chlorophyll concentration in the area where plants such as grass and grass as the first landing zone 1a and the second landing zone 2a of the airport A1 grow. This is data for determining the amount of water spray and fertilizer, disinfectant, herbicide and other sprays in this area based on experience. The reference data is stored in the database Db1 in a table format, for example. However, the reference data is based on the two parameters of soil moisture and chlorophyll concentration in the area where plants such as turf and grass grow at the airport A1, and the amount of water spray and fertilizer in this area based on the knowledge and experience of workers. However, the present invention is not limited to data for determining the spray amount of a bactericide, a herbicide or the like. As long as the standard data can determine the work necessary for maintenance of the area where plants grow such as grass and grass in the airport from various parameters as well as knowledgeable and experienced workers. Good.

  The computer system Cs shown in FIG. 2B may have a database Db2 that stores map data indicating a map of the airport A1 in addition to the database Db1. In this case, the work information generated by the data processing unit Dp can be information in a map format indicating work necessary for maintenance on the map of the airport A1. For example, in this map format information, an area where watering is necessary is indicated by a specific color, and an area where the required amount of watering is large is indicated by a darker color than an area where the required amount of watering is small. Furthermore, in this map format information, areas that require spraying, such as fertilizers, fungicides, and herbicides, are color-coded in specific colors, and areas that require a large amount of spray are areas that require a small amount of spray. Shown in a darker color.

  In addition to the databases Db1 and Db2, the computer system Cs shown in FIG. 2B may have a database Db3 that stores data related to the growth of plants such as grass and grass. In this case, it is possible to accumulate data related to the growth of plants such as grass and grass in the individual landing zones of the airport, and to standardize the work for managing and maintaining the landing zone of the airport.

  FIG. 3 shows an example of processing executed by the computer system Cs shown in FIG. 2B.

  Step Pa: The computer system Cs includes at least one vehicle V while the one or more vehicles V are moving on at least one area where plants such as grass and grass are growing (for example, the landing zone of the airport A1). Data related to the growth of plants such as grass and grass detected by at least one sensor mounted on one or more vehicles at at least one point in the area (for example, the environment where plants such as grass and grass are growing) And / or growth state data indicating the growth state of plants such as turf and grass). Environmental data includes, for example, data indicating soil moisture in areas where plants such as turf and grass including the landing zone grow, data indicating temperature in this area, data indicating humidity, data indicating wind direction, soil pH It includes at least one piece of data indicating a value. The data indicating the growth state of plants such as turf and grass includes, for example, data indicating the chlorophyll concentration of plants such as turf and grass. However, the data indicating the growth state of plants such as turf and grass may further include data indicating the height of plants such as turf and grass. Data relating to the growth of plants such as grass and grass detected by sensors mounted on one or more vehicles is transmitted wirelessly from one or more vehicles and received by the computer system Cs via a wireless network. Thus, it may be acquired by the computer system Cs. Alternatively, when data related to the growth of plants such as grass and grass detected by sensors mounted on one or more vehicles is stored in the medium memory in one or more vehicles, the medium memory is stored in a computer. It may be obtained by the computer system Cs by inserting it into the slot of the system Cs. The aspect in which the computer system Cs acquires data related to the growth of plants such as grass and grass detected by at least one sensor mounted on one or more vehicles may be any aspect.

  Step Pb: The computer system Cs generates information that can be used for maintenance of the landing zone of the airport A1, based on the data related to the growth of plants such as turf and grass acquired in Step Pa. Here, the information that can be used for maintenance of the airport A1 may be data itself related to the growth of plants such as grass and grass. Alternatively, the information that can be used for maintenance of the landing zone of the airport A1 may be work information indicating work necessary for maintenance of the landing zone of the airport A1. For a specific example of how the computer system Cs generates work information indicating work necessary for maintenance of the landing zone of the airport A1, based on data related to the growth of plants such as grass and grass, This will be described later with reference to FIGS. 6A and 6B.

  Step Pc: The computer system Cs outputs the information generated in Step Pb (that is, information that can be used for maintenance of the landing zone of the airport A1). Here, the format of the information output from the computer system Cs can be any format. For example, information output from the computer system Cs may be printed on a paper medium or recorded on a recording medium. In this case, information that can be used for maintenance of the landing zone of the airport A1 can be provided to the airport A1 (for example, an administrator of the airport A1) in the form of a paper medium or a recording medium. Alternatively, the information output from the computer system Cs is transmitted to the airport A1 (for example, the manager of the airport A1) in a format transmitted from the computer system Cs to the terminal device of the manager of the airport A1 via a wireless or wired network. May be provided.

  FIG. 4 is a diagram for explaining the basic configuration of the above-described method for providing the airport maintenance service.

  Step S1: Data related to the growth of plants such as turf and grass (for example, environmental data indicating the environment in which plants such as turf and grass grow and / or growth state data indicating the growth state of plants such as turf and grass) The airport facility is provided with at least one vehicle equipped with at least one sensor for detecting.

  Step S2: lawn or grass detected by at least one sensor at at least one point in at least one area while at least one vehicle is moving on at least one area (landing zone) of the airport facility Based on the data related to the growth of plants, information that can be used for maintenance of airport facilities is generated.

  Step S3: The information generated in step S2 is provided to an airport facility (for example, an airport facility manager).

(vehicle)
FIG. 5 is a diagram illustrating an example of the configuration of the vehicle V in the maintenance management system 100.

  The vehicle V includes a drive unit 20 for moving the vehicle, a drive control unit 30 that controls the drive unit 20, a sensor unit 40 that detects data related to the growth of plants such as grass and grass, and the sensor unit 40. And a data processing unit 10 for processing data related to the growth of plants such as turf and grass detected by. Environmental data included in data related to the growth of plants such as grass and grass (data indicating the environment in which plants such as grass and grass are growing) include, for example, data indicating temperature, data indicating humidity, and wind direction. It is at least one of the data which show, the data which show soil water content, and the data which show soil pH value. The growth state data included in the data related to the growth of plants such as turf and grass (data indicating the growth state of plants such as turf and grass) is, for example, data indicating the chlorophyll concentration of plants such as turf and grass. .

  Here, data indicating the growth state of plants such as turf and grass can be obtained, for example, by measuring the concentration of chlorophyll (chlorophyll) contained in plants such as turf and grass using a chlorophyll sensor. This is because chlorophyll plays an important role in the photosynthetic reaction of plants such as turf and grass, and the growth state can be determined by its concentration.

  In FIG. 5, the sensor unit 40 includes a temperature sensor 41, a humidity sensor 42, a wind direction sensor 43, a soil moisture amount sensor 44, a soil pH sensor 45, and a chlorophyll sensor 46. What is necessary is just to include at least one of the sensors 41 to 46. In particular, if the amount of water in the area where plants grow such as grass and grass at the airport (for example, the landing zone) increases, many insect pests that feed on birds such as earthworms are generated, which increases the number of birds that fly. As a result, the probability of bird strikes increases, so it is important to identify and deal with places with high soil moisture in the landing zone. Accordingly, the sensor unit 40 of the vehicle V used at the airport preferably includes a soil moisture sensor 44. In addition, from the viewpoint of grasping the growth state of plants such as grass and grass in the landing zone, the sensor unit 40 preferably includes a chlorophyll sensor 46.

  Here, the data processing unit 10 stores the data detected by each sensor of the sensor unit 40 in the internal memory 11 in association with position data indicating at which point in the airport landing zone the data is measured. Is configured to do. The method for acquiring the position data indicating the position of the measurement point is not particularly limited, and there are a method for calculating based on the distance and direction moved from the reference position, a method for calculating using a satellite positioning system, and the like. Data related to the growth of plants such as turf and grass stored in the memory 11 is provided to the maintenance management system 100 of the office 1000 by wireless communication, wired communication, or via a portable recording medium.

  The drive unit 20 includes a power source such as an engine and a motor, a steering mechanism, and one of wheels, caterpillars, legs, etc. that are in contact with the ground plane L. It is configured to allow reverse switching.

  The drive control unit 30 controls the drive unit 20 so that the vehicle V moves along a predetermined course. For example, the drive control unit 30 controls the drive unit so that the vehicle travels along a guidance line installed in the airport landing zone or uses a satellite positioning system on the map data of the airport landing zone. The drive unit is controlled so as to move on the landing zone according to the set course. However, the configuration of the drive control unit 30 is not limited to these configurations.

  Next, a process for creating information used for maintenance of the landing zone 1a by the vehicle V in the first landing zone 1a of the airport A1 will be described.

  First, the configuration of the first runway 1 of the airport A1 and its surroundings will be briefly described.

(First runway 1 of airport A1)
6A and 6B are a plan view and a perspective view showing an example of the configuration of the first runway 1 of the airport A1 and its surroundings.

  A first landing zone 1 a is provided on both sides and both ends of the first runway 1 so as to surround the first runway 1. A guideway 1c is provided along the first runway 1 to connect the first runway 1 and the first apron 1b (see FIG. 2C).

  Next, a procedure for creating information used for maintenance of plants such as grass and grass in the first landing zone 1a will be described.

  As shown in FIG. 1B, this airport A1, together with neighboring airports A2 to A3, forms a unit U1 that is a unit in which maintenance service is provided by the business establishment 1000.

  When the maintenance service is provided to the airports A1 to A3 of the unit U1, one or more vehicles V are introduced from the business office 1000 to the airport A1. Here, two vehicles V are thrown into the first landing zone 1a of the airport A1, and as shown in FIG. 6B, one vehicle V is connected to one end of the first runway 1 in the first landing zone 1a ( The vehicle V is arranged at the detection start point Sp2 close to the other end of the first runway 1 in the first landing zone 1a (the right side at the back of the paper). Shall be. Here, a case where the sensors 41 to 46 of each vehicle V detect temperature data, humidity data, wind direction data, soil moisture amount data, soil pH data, and chlorophyll concentration will be described.

  The vehicle V arranged at the detection start point Sp1 moves along the route P1, and at a plurality of positions along the route P1, the sensors 41 to 46 have temperature data, humidity data, wind direction data, and soil moisture content. Detect data, soil pH data, chlorophyll concentration. The detected data is stored in the internal memory 11 in association with the position data indicating the detected position by the data processing unit 10. The vehicle V that departs from the detection start point Sp2 moves along the path P2, and at a plurality of positions along the path P2, the sensors 41 to 46 have temperature data, humidity data, wind direction data, soil moisture data, soil Detect pH data and chlorophyll concentration. The detected data is stored in the internal memory 11 by the data processing unit 10 in association with position data indicating the detected position. Here, the position data may be data indicating the position of the airport A1 with respect to the reference position, or position data indicated by latitude and longitude information by the satellite positioning system. Further, it may be position data indicating the position indicated on the map of the airport A1 based on the latitude and longitude information by the satellite positioning system.

  When data relating to the growth of plants such as turf and grass in the first landing zone 1a is detected by the two vehicles V in this way, the plant of turf and grass and the like is similarly detected in the second landing zone 2a. Data related to growth is detected and stored in the memory 11 of the data processing unit 10.

  Such detection processing of data related to the growth of plants such as grass and grass at the airport is performed in parallel at the three airports A1 to A3 in the unit U1. The vehicles V are returned to the office 1000 from the two airports A1 to A3 almost simultaneously.

  Data related to the growth of plants such as turf and grass and stored in the memory 11 of the data processing unit 10 of the plurality of vehicles V collected in the business office 1000 is the computer system Cs of the maintenance management system 100 shown in FIG. 2A. To the data processing unit Dp (FIG. 2B). The data transfer from the vehicle data processing unit 10 to the data processing unit Dp of the computer system Cs may be performed via a recording medium, or may be performed via a network such as a wired LAN or a wireless LAN. . Furthermore, the maintenance management system 100 provided in the office 1000 is configured to include a wireless communication unit, and the vehicle V is configured to include a wireless communication device, and the data processing unit 10 of the vehicle V is associated with position data. Data related to the growth of plants such as grass and grass may be received by the maintenance management system 100 provided in the business establishment 1000 by a wireless communication device and output to the computer system Cs.

  When data related to the growth of plants such as turf and grass is provided to the data processing unit Dp of the computer system Cs, the data processing unit Dp refers to the reference data in the database Db1 and the growth of plants such as turf and grass. Work information indicating work necessary for maintenance of the landing zone of each of the airports A1 to A3 of the unit U1 is created based on the data related to. This work information is provided from the office 1000 to each of the airports A1 to A3 of the unit U1.

  This work information indicates work required in a work area such as the first landing zone 1a. This work information may be information obtained from data indicating the state of the first landing zone 1a, for example. This work information is, for example, information reflected in subsequent work plans, airport facility measures, and the like. The data indicating the state of the first landing zone 1a is measured at an arbitrary measurement point of the first landing zone 1a. As such work information, work information necessary for maintenance of plants such as grass and grass in the first landing zone 1a and the second landing zone 2a of the airport A1 is provided to the airport A1. Also, the airport A2 and the airport A3 are provided with work information necessary for maintenance of plants such as turf and grass in the respective landing zones, similarly to the airport A1.

  In addition to the data related to the growth of plants such as turf and grass on the vehicle V, the work information depends on what data is detected as data representing the maintenance state of the airport facility, depending on the flight of birds, removal of dead leaves, etc. Can be indicated. Furthermore, the work information can also instruct the coloring work of plants such as grass and grass in the landing zone. In coloring (coloring), the growth state of plants such as turf and grass is determined from data indicating the growth state of plants such as turf and grass included in the data related to the growth of plants such as turf and grass. Based on the results, a method of spraying a colored powder of scallop shells can be used. The colorant for coloring plants such as turf and grass is preferably green and has an adhesive property to take up dust or dust (for example, dust) that has risen in the air due to takeoff or landing of an aircraft. As a result, the boundary between the runway of the asphalt and the landing zone of the green zone becomes clear, and the rise of dust and the like is reduced, and as a result, the safety of the aircraft operation is expected to be improved. Further, the colorant may not have such adhesiveness. In addition to or instead of this stickiness, the colorant has at least one of quasi-incombustibility in consideration of an emergency fire and the like and a property that promotes photosynthesis of plants such as grass and grass. You may do it. For example, the colorant can have the property of promoting plant photosynthesis depending on the color of the colorant. By promoting such photosynthesis, the underground temperature of the area where plants such as turf and grass grow can be increased as compared with that before coloring. Further, taking advantage of the characteristic of the colorant that the underground temperature is warmer than before coloring, a snow melting effect may be obtained with a certain amount of snowfall.

  In addition, it is possible to instruct the coloring work for winter withering plants such as grass and grass in winter based on seasonal information.

  Seasonal information can be obtained from the clock function of the computer system Cs. The color of plants such as turf and grass can be determined by an image sensor or the like. Therefore, it is possible to create information instructing an operation for coloring a plant such as lawn or grass that has withered in winter to an approximate color (green) based on the output of the sensor.

  After that, according to the schedule information at the office 1000, when the business operator inputs a plurality of vehicles collected from the airports A1 to A3 of the unit U1 to the airports A4 to A5 of the unit U2, the airports A1 to A1 of the unit U1. As performed in A3, data data relating to the growth of plants such as grass and grass is detected by the vehicle V at each of the airports A4 to A5 of the unit U2. The schedule information at the office 1000 is a vehicle patrol work plan that takes into account the region, season, etc., and indicates how often the airport facility maintenance service is provided to which airport throughout the year. It is a plan. Thereafter, the vehicle V is collected in the business establishment 1000. A computer system of the maintenance management system 100 in which data relating to the growth of plants such as grass and grass stored in the memory 11 of the data processing unit 10 of the vehicle V collected in the business establishment 1000 is installed in the business establishment 1000. When provided to Cs, the data processing unit Dp of the computer system Cs creates work information indicating work necessary for maintenance of the airports A4 to A5 of the unit U2.

  This work information is provided from the office 1000 to each of the airports A4 to A5.

  As described above, the first embodiment provides the airports A1 to A5 with the vehicle V equipped with a sensor that detects data related to the growth of plants such as turf and grass (for example, environmental data and / or growth state data). Then, based on the data detected using the sensor of the vehicle V, work information indicating work necessary for maintenance of the landing zone of each airport A1 to A5 is created, and the created work information is provided to each airport A1 to A5. Therefore, in each airport A1 to A5, the work standards can be clarified and shared, so that even a worker with little knowledge and experience or an unmanned work vehicle can maintain the landing zone of the airport facility based on the work information. Work necessary for management can be efficiently performed. As a result, the necessary expenses for maintenance of the airport facility can be reduced.

  In particular, based on the detected environmental data and / or growth state data, work necessary for maintenance and management of the airport landing zone by the computer system Cs with reference to reference data indicating the judgment criteria of an operator having experience and knowledge Therefore, the shortage of workers with experience and knowledge can be resolved.

  Airport facilities have many aircraft takeoffs and landings that can only be operated at night, facilities that have few aircraft takeoffs and landings and can be operated during the day while confirming the operation status, and problems such as noise from nearby work Since there are facilities in various situations, such as facilities that cannot be operated at night, work required for maintenance of airport facilities is carried out by unmanned work vehicles based on work plans that take into account the status of each airport. Can avoid bad work. Furthermore, since environmental data and / or growth state data can be accumulated at airport facilities, standardization of work necessary for maintenance of airport facilities such as landing zones, where plants such as turf and grass grow, is planned. You can also.

  Furthermore, the system for creating work information indicating work necessary for airport facility maintenance management is provided by the business establishment 1000 that provides airport facility maintenance management services. No need to purchase. As a result, equipment maintenance and fuel costs are reduced, and personnel reduction can be achieved by unmanned operation.

  In the first embodiment, a vehicle V equipped with a sensor for detecting data related to the growth of plants such as grass and grass in the airport facility is provided to the airports A1 to A5, and data detected using the vehicle V is detected. We have explained the case where the establishment 1000 provides services up to providing the airports A1 to A5 with work information indicating the work necessary for maintaining the landing zones of the airports A1 to A5. The station 1000 may also provide the airport with a service for performing work necessary for maintenance of the airport facility indicated by the work information.

  In this case, since the office 1000 also provides unmanned vehicles and the like that work based on the work information to the airport, it is not necessary to purchase the latest general-purpose machine for maintaining the landing zone at the airport. Furthermore, in the operation by the unmanned vehicle, the influence of the weather is reduced.

  Hereinafter, the airport facility maintenance service provided from the office to the airport in this way is based not only on the service that provides the airport with work information indicating the work required for the airport facility maintenance, but also on the basis of this work information.

  Hereinafter, as a maintenance service for an airport facility, a method for performing coloring work of plants such as turf and grass against the withering of plants such as turf and grass in a landing zone according to the season will be described as a fifth embodiment.

(Embodiment 5)
A method for providing a maintenance service according to the fifth embodiment of the present invention will be described with reference to FIGS. 17A to 17C.

  FIG. 17A shows a plurality of airports A1 to A5 that are handled by establishments that provide the maintenance service, and FIG. 17B shows a state in which a plurality of airport facilities that are handled by the establishments that provide the maintenance service are grouped. Reference numeral 17C denotes an office maintenance management system.

  Also in the fifth embodiment, as shown in FIGS. 17A and 17B, the maintenance management service to the airport is provided by a plurality of airports A1 to A5 that one office 5000 is responsible for, as in the first to fourth embodiments. The two units U1 and U2 are grouped and performed for each group.

  In the fifth embodiment, as shown in FIG. 17C, the maintenance management system 500 provided in the business office 5000 is replaced with a plurality of vehicles V included in the maintenance management system 100 of the first embodiment, such as grass and grass. A work vehicle Vf having a configuration capable of coloring plants such as turf and grass while moving on the area where the plants grow is included. Here, the computer system Csf of the maintenance management system 500 is configured to obtain work data indicating work performed by the work vehicle Vf, and to create and output a work report based on the obtained work data. Yes.

(Work vehicle Vf)
As shown in FIG. 18, the work vehicle Vf includes a work control unit 10f that replaces the work control unit 10a of the work vehicle Va of the second embodiment. Further, as the work device 50 of the work vehicle Va of the second embodiment, It is provided with a coloring means 50a for coloring plants such as grass. The coloring means 50a is configured to color plants such as turf and grass on the landing zone while the work vehicle Vf is moving on the landing zone. In the memory 11f of the work control unit 10f, route information for moving the work vehicle Vf along a predetermined route is recorded. The work control unit 10f controls the drive control unit 30 and the coloring unit 50a so that the coloring unit 50a colors plants such as grass and grass while the drive control unit 30 drives the driving unit 20. It is configured.

  The drive unit 20 and the drive control unit 30 are the same as those of the work vehicle Va of the second embodiment.

  Next, the maintenance service provided by the maintenance management system 500 of the fifth embodiment will be specifically described by taking the airport A1 as an example.

  As shown in FIGS. 19A and 19B, the work vehicle Vf of the maintenance management system 500 is thrown into the airport A1 from the office 5000. Here, two detection work vehicles Vf are put into the first landing zone 1a of the airport A1, and one work vehicle Vf is one end of the first runway 1 in the first landing zone 1a as shown in FIG. 15B. The work start point Sp1 is located near the work start point Sp1 close to (the front left side of the page), and the other work vehicle Vf is close to the work start point Sp2 close to the other end of the first runway 1 in the first landing zone 1a (the right side on the back of the page). Be placed.

  The work vehicle Vf arranged at each work start point Sp1, Sp2 moves the landing zone 1a along the paths P1, P2, and colors plants such as grass and grass on the movement path of the work vehicle Vf with a colorant. To do. Plants such as turf and grass are colored when the green of plants such as turf and grass still remains (for example, around November), rather than being colored green after plants such as turf and grass become white due to withering in winter. ) It is more efficient to go. The colorant is preferably green and has a tackiness to take up dust or dust that has risen in the air due to takeoff or landing of the aircraft. In this way, by using an adhesive colorant for coloring plants such as turf and grass, it is possible to prevent dust and dust that have risen during takeoff and landing of the aircraft from entering the engine. However, the coloring of plants such as grass and grass is not limited to the method using a coloring agent.

  Specifically, when the work vehicle Vf starts to move on the first landing zone 1a, the coloring means 50a is controlled by the work control unit 10f, such as turf or grass where the landing zone work vehicle Vf passes. The process of coloring the plant green with a colorant is started. Further, when the work vehicle Vf moves along a predetermined route on the first landing zone 1a and stops at the end position, the coloring means 50a greens the plant such as turf or grass with a colorant under the control of the work control unit 10f. Stop the coloring process.

  When the work of coloring the plants such as turf and grass is completed by the two work vehicles Vf in the first landing zone 1a in this way, the turf and grass etc. are similarly applied to the remaining second landing zone 2a. The plant is colored.

  The execution of the coloring work of plants such as turf and grass in the airport landing zone is performed in parallel at the three airports A1 to A3 in the unit U1, and after completion, the third embodiment or the fourth embodiment. Similarly, the work vehicle Vf is returned to the business office 5000 almost simultaneously from the three airports A1 to A3 in the unit U1.

  After that, according to the schedule management, the airport facility maintenance management service is provided to the airports A4 to A5 of the other unit U2 in the same manner as the airports A1 to A3 of the unit U1.

  Thus, in the fifth embodiment, the work vehicle Vf equipped with the coloring means 50a for coloring plants such as grass and grass to green is provided to the airports A1 to A5, and this work is performed while moving on the landing zone of the airport facility. Since the vehicle Vf colors the turf and grass in the landing zone, it can be avoided that the contrast between the runway and the landing zone is reduced due to winter death of plants such as the turf and grass in the landing zone. The function of the landing zone, which plays an important role in the safe operation of the aircraft, can be maintained, and the safe operation of the aircraft can be ensured.

  In the fifth embodiment, the colorant has been shown to have the adhesiveness to take up dust or dust that has risen in the air due to takeoff or landing of the aircraft, but the colorant does not have such adhesiveness. It may be a thing. In addition to or instead of this stickiness, the colorant has at least one of quasi-incombustibility in consideration of an emergency fire and the like and a property that promotes photosynthesis of plants such as grass and grass. You may do it. For example, the colorant can have the property of promoting plant photosynthesis depending on the color of the colorant. By promoting such photosynthesis, the underground temperature of the area where plants such as turf and grass grow can be increased as compared with that before coloring. Further, taking advantage of the characteristic of the colorant that the underground temperature is warmer than before coloring, a snow melting effect may be obtained with a certain amount of snowfall.

  In the fifth embodiment, the work vehicle Vf includes only the coloring means 50a for coloring plants such as turf and grass as a work device. However, the work vehicle Vf further includes plants such as turf and grass. It may be provided with a mowing means for mowing.

Further, as the work device 50 of the work vehicle Va according to the second embodiment, turf, grass, and the like are provided. Coloring means 50a for coloring the plants, and mowing means 50b for cutting plants such as grass and grass.

  As in the work vehicle Vf of the fifth embodiment, the coloring means 50a is configured to color plants such as grass and grass on the landing zone while the work vehicle Vg is moving on the landing zone. Yes. The mowing means 50b is configured to mow plants such as grass and grass on the landing zone while the work vehicle Vg is moving on the landing zone.

  In the memory 11g of the work control unit 10g, route information for moving the work vehicle Vg along a predetermined route is recorded. The work control unit 10g is configured such that the coloring of the plants such as grass and grass by the coloring unit 50a and the mowing of the mowing unit 50b are performed while the driving control unit 30 is driving the driving unit 20. The coloring means 50a and the mowing means 50b are configured to be controlled.

  The drive unit 20 and the drive control unit 30 are the same as those of the work vehicle Va of the second embodiment.

  With the work vehicle Vg having such a configuration, it is possible to color green on plants such as turf and grass while mowing in the landing zone, and effectively color the plants such as turf and grass shortened by mowing. It can be performed.

  In the work vehicle Vg shown in FIG. 20, the work control unit 10g controls the coloring means 50a and the mowing means 50b so that the coloring means 50a performs coloring of plants such as grass and grass and the mowing means 50b. However, the configuration of the work control unit 10g is not limited to such a configuration.

  For example, the work control unit 10g allows the coloring means 50a to color the plants such as grass and grass after the cutting means 50b cuts the plants such as grass and grass before the plants such as grass and grass wither in winter. The mowing means 50b and the coloring means 50a may be controlled so as to be performed once or several times. Alternatively, the work control unit 10g allows the coloring means 50a to color the plants such as turf and grass after the cutting means 50b cuts the plants such as turf and grass before the plants such as turf and grass wither in winter. In addition, the mowing unit 50b and the coloring unit 50a may be controlled so as to adjust the shade of the coloring agent when coloring plants such as turf and grass.

Furthermore, in Embodiment 5 described above, the maintenance management system has been described for the case where the coloring work of plants such as turf and grass is performed in the landing zone. However, the maintenance management system performs this coloring work other than the landing zone in the airport. You may carry out in the area | region where plants, such as turf and grass, for example, in the park in an airport, for example, the area | region where plants, such as grass and grass around a taxiway or an apron, grow.

A large sound may be generated by a large sound generator to threaten the bird. For example, the laser device for bird damage countermeasures may be a thermography laser beam facility. Furthermore, during the summer season when grass is growing significantly, the number of unattended mowing such as mowing is increased using vehicles equipped with the above-mentioned mowing means, thereby suppressing the formation of bird nests flying to airport facilities. Thus, bird strikes can be reduced. Note that the harvested grass after unattended mowing can be efficiently collected by using an unmanned roll baler or the like. Furthermore, thatch (grass debris) that occurs after unattended mowing reduces the amount of residual material after mowing by spraying the decomposing agent with, for example, a working device that sprays the decomposing agent mounted on the work vehicle. can do.

  In addition, the airport facility maintenance management service patrol plan provided by the offices of each of the above embodiments is a year-round plan taking into account the region and seasons, etc., so that the maintenance management system installed at each office The operating efficiency of vehicles equipped with can be improved.

  In addition to the maintenance of grass, the state of dead leaf accumulation and the occurrence of pests are also subject to maintenance at the airport. Accordingly, by using a sensor capable of detecting these maintenance targets, for example, an image sensor, as a sensor mounted on the vehicle, it is possible to maintain and manage things other than grass at the airport. In particular, the damage to grass caused by pests can be effectively suppressed by predicting and dealing with the occurrence of large numbers of insects, and in the future, pests will be realized by realizing sensors capable of detecting such signs of large-scale occurrence. It is possible to almost eliminate the damage caused by grass.

Specifically, the vehicle main body 902a includes a grass powder storage unit 902 that stores grass powder CGr, a discharge means 924 for discharging the grass powder CGr from the grass powder storage unit 902, and the discharged grass powder CGr. And a conveying blower 925a that conveys in a flow, and is configured such that grass powder is conveyed by the conveying blower 925a to the snow removal device 902b via the conveying duct 925b. Here, the grass powder is obtained by finely pulverizing and coloring grass produced in the summer mowing operation, and is stored in a warehouse in the airport for recycling. The grass powder is transported from the warehouse as needed during snow removal work in winter and loaded into the rotary snowplow AVh2.

  The snow removal device 902b includes a cylindrical snow scraping roller 926 that scrapes snow by rotation, a pair of left and right roller support plates 926a that rotatably supports the snow scraping roller 926, and a pair of upper and lower support plates that support each roller support plate 926a. And a support arm 926b. Here, the roller support plate 926a incorporates a motor for rotating the snow scraping roller 926. One end of the support plate support arm 926b is fixed to the roller support plate 926a, and the other end of the support plate support arm 926b is rotatably attached to the vehicle body 902a. The support plate support arm 926b is rotated by an actuator (not shown) attached to the vehicle main body 902a.

  The snow removal device 902b further includes a mixer 927 that mixes the grass powder conveyed from the vehicle main body 902a with the snow scraped off by the snow scraping roller 926, and a snow blowing unit 928 that blows out the snow SGm mixed with the grass powder. Have. The snow outlet 928 includes an outlet pipe 928a and an outlet blower 928b. The mixer 927 is fixed to the roller support plate 926 a, and the snow blowing part 928 is attached to the upper part of the mixer 927.

  In this rotary type snowplow AVh2, the drive unit 220 and the drive control unit 330 are the same as those in the side-by-side snowplow AVh1, and the work control unit 920 is the work control unit 910 of the side-by-side snowplow AVh1. In the same manner as the above, a transmission / reception unit (not shown) for transmitting / receiving information to / from the computer system ACsh via a line such as a memory 921 and a wireless LAN is provided. However, the work control unit 920 controls the drive control unit 330 based on the work content instructed by the computer system ACsh, and also carries out motors for the carry-out means 924, the transport blower 925a, the mixer 927, the blower blower 928b, and the snow scraping roller 926. The actuator of the mounting plate support arm 926b is configured to be controlled.

  Next, the maintenance service (snow removal work) provided to the airport shown in FIG. 22 by the office 9000a will be described.

  When the computer system ACsh of the maintenance management system 900a of the business establishment 9000a acquires the snow cover information of the airport shown in FIG. 22, it instructs the side-by-side snowplow AVh1 and the rotary snowplow AVh2 to perform snow removal work. This instruction is received by the work control unit 910 of the side-by-side snowplow AVh1 and the work control unit 920 of the rotary snowplow AVh2 via a line such as a wireless LAN. Here, it is assumed that the side-by-side snowplow AVh1 and the rotary snowplow AVh2 are brought into the airport in advance from the office based on the weather forecast and stored in a hangar or the like in the airport.

  First, a plurality of side-by-side snowplows AVh1 perform snow removal work on the runway.

  FIG. 24B is a diagram for describing an example of snow removal work by the side-by-side snowplow AVh1 shown in FIG. 24A.

  The work control unit 910 of the plurality of side-by-side snowplows AVh1 detects the position of the center line of the runway 61 based on the map information of the airport, and each according to the work content (execution of snow removal work) instructed by the computer system ACsh. The travel position with respect to the center line of the runway 61 of the snowplow is determined. When the running position of each side-by-side snowplow AVh1 is determined, the plurality of side-by-side snowplows AVh1 are arranged such that the side-by-side snowplow AVh1 running on the center line of the runway 61 starts as shown in FIG. 24B. A formation is formed so that a plurality of side-aligned snowplows AVh1 are arranged on both sides, and the runway 61 travels from one end side to the other end side. The snow Sn piled up on the runway 61 is brought to both sides of the runway 61 by the run of the side snowplow AVh1 on the runway 61. The operation of bringing snow to the side of the runway in this way is usually completed by the side-by-side snowplow AVh1 running on the runway 61 one to several times. FIG. 24C shows a state where the snow removal work by the side-by-side snowplow AVh1 shown in FIG. 24A is completed. When the snow removal work by the side-by-side snowplow AVh1 is thus completed, the snow removal work by the rotary snowplow AVh2 is subsequently performed.

  FIG. 25B is a diagram for describing an example of snow removal work by the rotary snowplow AVh2 shown in FIG. 25A.

  Here, the plurality of rotary type snowplows AVh2 perform a snow removal operation for removing snow collected on the side of the runway, and at the same time, the boundary between the runway 61 and the landing zones 6a on both sides of the runway 61 becomes clear. In particular, the work of coloring the landing zone regions on both sides of the runway 61 is performed. The coloring operation is performed by scattering grass powder stored in the airport warehouse on the landing zone 6a.

  This will be specifically described below.

  In advance, grass powder CGr carried out from an airport warehouse is loaded in the grass powder container 902 of a plurality of (for example, two) rotary snowplows AVh2. When the work control unit 920 of the rotary snowplow AVh2 receives an instruction of work content (snow removal work) from the computer system ACsh, the work control unit 920 detects the position of the center line of the runway 61 based on the map information of the airport. Then, based on the work content (snow removal work) instructed from the computer system ACsh, the travel position of the snowplow with respect to the center line of the runway 61 is determined. In the case of the rotary type snow removal vehicle Vh2, since the snow removal work for removing the snow that has been moved to the side of the runway 61 by the side-by-side snow removal vehicle AVh1 is performed, the scenery in front of the vehicle is photographed by an image sensor or the like while the vehicle is running, You may make it determine the driving | running | working position optimal for snow removal work by analysis of the image | photographed image.

  When the two rotary snowplows AVh2 are positioned at the snow removal start position (for example, both side portions on one end side of the runway 61) and the snow removal work by the rotary snowplow AVh2 is started, The snow collected on both sides of the runway 61 is taken in by the snow scraping roller 926 of the snow removal device 902b, and the taken-in snow is blown out toward the landing zone side by the snow blowing portion 928 via the mixer 927. While the snow is being taken in and blown out, in the rotary type snowplow AVh2, the grass powder stored in the grass powder storage section 902 is transported to the transport blower 925a by the transport means 924, and further, the grass The powder is conveyed to the mixer 927 by the conveying blower 925a through the conveying duct 925b. Since the snow taken in by the snow scraping roller 926 is supplied to the mixer 927, in the mixer 927, the grass dust is mixed into the snow, and the snow SGm containing the grass is directed from the snow blowing portion 928 toward the landing zone side. And blown out. For this reason, the portion of the landing zone 6a adjacent to the portion of the runway 61 where the snow removal work by the rotary snowplow AVh2 has been completed, as shown by the dot display in FIG. Will be colored.

  The operation of blowing off the snow collected on the side of the runway in this way is usually completed when the rotary snowplow AVh2 runs on the runway 61 at least once. FIG. 25C shows a state where the snow removal work by the rotary snowplow AVh2 shown in FIG. 25A is completed.

  The snow removal work by the side-by-side snowplow AVh1 and the rotary snowplow AVh2 is performed not only on the runway 61 but also on the taxiway 6c.

  However, at the airport, there are cases where the snow is removed from the runway 61 and the hands are not sufficiently turned until the snow is removed from the taxiway 6c. In such a case, snow removal on the taxiway 6c may be only snow removal by the rotary snowplow AVh2. Because, in the taxiway 6c, the aircraft only moves by low-speed ground travel, so even if there is a little snow, if the boundary between the taxiway and the surrounding green zone (the taxiway green zone) can be clarified This is because the aircraft can move on the taxiway. Specifically, when the rotary snowplow AVh2 removes snow from the side edge of the taxiway, snow containing colored grass powder is scattered to the area around the taxiway (the green area of the taxiway). Road green zone is colored. As a result, the pilot can recognize both side edges of the taxiway.

  As described above, when the snow removal work on the runway 61 and the taxiway 6c is completed, the aircraft can be taken off and landing at the airport.

  When snow continues to fall, the snow removal work by the side-by-side snowplow AVh1 and the rotary type snowplow AVh2 is intermittently performed. However, when the snow has stopped, the side-by-side snowplow AVh1 and the rotary type snowplow AVh1. The snow removal work by the snowplow AVh2 is finished, and these work vehicles are returned to the hangar or the like. Furthermore, when it is predicted by the weather forecast that it will not snow for a while, these work vehicles are once returned to the office 9000a.

  As described above, in the sixth embodiment, the side-by-side snowplow AVh1 and the rotary type snowplow AVh2 are provided to the airport, and the snowplow work of the aircraft running roads such as the runway 61 and the taxiway 6c of the airport facility is provided by these snowplows. Since the landing zone and the taxiway green zone are colored at the same time, the decrease in contrast between the road and the area around the road (green zone) due to snow can be improved simultaneously with the snow removal work on the road. Thereby, even in heavy snowy areas in winter, it is possible to maintain the functions of the roadway and the surrounding green zone that play an important role in the safe operation of the aircraft, and to ensure safe operation of the aircraft.

  In the sixth embodiment, for the coloring, grass powder obtained by finely pulverizing and coloring the cut grass is used, but in order to color the snow, the snow taken into the rotary snowplow AVh2 is used. You may make it mix | blend the ash and charcoal obtained by baking the cut grass. If charcoal is mixed, the surface of the landing zone and taxiway green area will become black and the absorption of sunlight will be promoted, so the temperature will rise and snow melting and the photosynthesis of grass in the landing zone and taxiway green area will be Promoted. In the rotary type snowplow AVh2, it goes without saying that a snow melting agent may be mixed into the taken-in snow and the snow may be blown off together with the snow melting agent.

  Further, to color the snow taken in the rotary snowplow AVh2, a scallop shell crushed or a scallop shell crushed color may be used. Because the scallop shells have a glossy surface, the surface of the landing zone and the taxiway green zone can be obtained by mixing the ground pieces of the scallop shells with the snow and rolling them over the landing zone and the taxiway green zone, even if not colored. Since it shines by receiving sunlight, the boundary between the runway 61 and the landing zone 6a and the boundary between the taxiway 6c and the taxiway green zone become clear.

  In addition to the winter snow removal work, some airport facility maintenance management services according to the weather also provide a puddle removal work due to heavy summer guerrilla rain.

  Specifically, the area where the plants grow around the runway, such as the runway and taxiway (green zone) is not flat and uneven, so the landing zone and taxiway around the runway due to heavy guerrilla rain in summer, etc. There may be water pools in the surrounding taxiways. If you leave the puddles in the area where plants grow around the road in this way, many pests that feed on birds such as earthworms will be generated, which increases the number of birds flying to the airport. This causes a bad effect that the probability of occurrence of a bird strike increases. Especially in subtropical areas such as Southeast Asia, the phenomenon of storms with heavy rains (scalls) frequently occurs, so airport facilities in such areas are subject to such heavy rains (for example, up to 100 mm per hour) in advance. Although designed in consideration, if guerrilla heavy rain (for example, 300 mm per hour) occurs, water may be accumulated in a green zone (region where plants grow) around the traveling path. For this reason, depending on the airport, it is necessary to remove the puddle formed in the green zone due to guerrilla heavy rain, and the puddle formed in the green zone is also subject to maintenance of the airport facility.

  Hereinafter, a method for providing a service for performing a puddle removing operation for removing a puddle formed in a green zone around a traveling road as an airport facility maintenance management service will be described as a seventh embodiment.
