Description

Real-time perception system for firefighters' on-site location and its application method

technical field

The invention relates to the fire emergency field, and proposes a data modeling-based real-time perception system for firefighters' on-site positions and a method for using the same.

Background technique

For a long time, fire has caused serious threats to human life and property. In the emergency treatment of fire, the faster the fire can be controlled, the greater the loss of life and property can be reduced. However, there are still many problems in the fire emergency response of the fire brigade at present, and it is difficult to meet the rescue needs of modern fire disaster processing.

On the one hand, the fire protection acceptance method at this stage is that the unit to be accepted submits the fire protection acceptance declaration form, the project completion acceptance report and other materials, the firefighters conduct on-site sampling inspections and perform functional tests, and fill in the basic situation record form of construction project fire protection acceptance, building category, etc. , general layout and layout acceptance inspection record form, fire and smoke-proof separation, explosion-proof acceptance inspection record form and other materials. All materials such as data review, on-site sampling inspection, functional test, and comprehensive evaluation are stored in a booklet, and architectural drawings are stored in the form of electronic files. These materials have not been organized effectively by means, and have not been well utilized to help firefighters carry out rapid fire fighting and disaster relief when the building is on fire.

On the other hand, after the fire broke out, after the firefighters entered the fire scene, they could not know their location effectively and in real time only by using the drawings and simple communication with the on-site fire command system, nor could they know the situation of the surrounding fire facilities where they were located in real time. . Simultaneously, because the on-site fire control department cannot know the current location and environment information of the firefighters in time, it cannot effectively command the firefighters on-site rescue.

Contents of the invention

In order to solve the above-mentioned problems, the present invention can effectively use the information obtained during the fire inspection and acceptance through the data modeling of the information obtained during the fire inspection and acceptance, and use wireless transmission, voice navigation, GPS, RFID and other technologies, so that the firefighters at the fire scene can obtain real-time Information such as the location, quantity, and use of firefighting facilities in the surrounding environment, the location of evacuation doors, etc., and the on-site firefighting command system can also monitor the current location of firefighters and the surrounding environment in real time, and provide more targeted rescue work for firefighters command.

The purpose of the present invention is to propose a real-time perception system for firefighters' scene position based on data modeling and its application method. Effectively use the information during fire inspection and acceptance to increase the effectiveness of fire emergency rescue.

In order to achieve the above purpose, a real-time perception system for firefighters' on-site location based on data modeling and its use method of the present invention include the following four aspects in the application of fire acceptance and fire emergency:

1) Carry out data modeling for the information related to fire rescue work in the fire inspection and acceptance;

2) Use RFID, GPS, wifi wireless communication and other technologies to determine the current location of firefighters in real time, including longitude, latitude, and height (floor);

3) Compare the current location with the standard fire acceptance information data table after the fire information modeling, get the relative position of the firefighters in the building, and the information of the fire facilities within the set range of the current location, and report to the firefighters Display and voice broadcast.

4) The fire headquarters can also obtain the current location of firefighters and the information of surrounding firefighting facilities in real time at the same time, so as to give more targeted guidance to firefighters.

Among them, in the above 1), the information obtained in the fire acceptance is used for data modeling. According to the GA836-2009 fire acceptance standard, the fire acceptance needs to fill in the basic situation record form of construction project fire acceptance, building category, general layout and plane layout acceptance inspection record form, building interior decoration fire acceptance inspection record form, fire and smoke separation, explosion-proof Acceptance inspection record form, safety evacuation and fire elevator acceptance inspection record form, fire water source and fire power supply acceptance inspection record form, water fire extinguishing system acceptance inspection record form, automatic fire alarm system acceptance inspection record form, smoke prevention and smoke exhaust system acceptance inspection record Form, building fire extinguisher acceptance inspection record form, foam fire extinguishing system acceptance inspection record form, gas fire extinguishing system acceptance inspection record form, a total of 12 forms. This part screens the information obtained during the building fire acceptance, selects data related to fire emergency rescue for data modeling, and stores it in a SQL data table.

Among them, in the above 2), in this paper, the combination of GPS and RFID technology is mainly used as an example to determine the position of firefighters in real time.

Among them, in the above-mentioned 3), the position of the firefighter obtained in 2) is compared with the standard fire acceptance information data table in 1), and the fire-fighting facility information within a certain range of the firefighter’s current location is obtained, and the information is sent to the firefighter. Operators can perform flat display and voice broadcast.

Among them, in the above 4), the firefighters transmit the current location to the fire command system end in real time through the wireless communication network, and the commander at the fire command system end commands the firefighters according to the surrounding environment where the firefighters are located.

Compared with the existing fire emergency treatment method, the beneficial effects of the present invention are as follows: firstly, the effective information in fire inspection and acceptance is carried out into data modeling, and the data of fire inspection and acceptance is fully utilized. The second is that the present invention can obtain the current position of the firefighters and the information of the surrounding firefighting facilities in real time, and transmit them to the firefighters through plane display and voice playback, so that the firefighters can be familiar with the surrounding environment in real time. The third is that the fire command system can conduct more targeted command to firefighters by obtaining the current location of firefighters and the information of surrounding firefighting facilities in real time.

Detailed ways

In order to make the features and advantages of the present invention more clearly understood, below in conjunction with accompanying drawing, describe in detail as follows:

As shown in Fig. 1, it describes the structure diagram of firefighter fire scene rescue based on data modeling in the present invention, which is divided into two parts, namely the fire command system end and the individual soldier system end. The fire command system end and the individual soldier system end can communicate with each other through wifi, 3G, and WiMax wireless networks. One of the ways is to set up a wireless local area network on the fire scene command vehicle, which can be constructed through a WiMax wireless router (wireless access point or wireless bridge can also be selected), and the fire fighting individual device and field fire command system can be temporarily constructed It can also be connected to the fire department data center through the Internet in the wireless local area network if necessary. Download the fire acceptance information form of the current building to the individual system end before the emergency rescue at the fire scene, which can greatly reduce the dependence of the individual system end on the wireless communication system of the individual end and the command end. External wireless networks are only enabled for data communication without WLAN.

As shown in Figure 1, the fire command system includes four parts, namely the fire inspection and acceptance information database, the interaction system between the individual soldier and the command terminal, the on-site fire command system, and the fire department data center.

The data center of the fire department stores the fire acceptance information data sheets of all buildings in the city or within a certain scope of responsibility. The fire acceptance information data sheet refers to the data sheet established for each building in the city. Each building in the city corresponds to a SQL data table. Multiple fire acceptance information data sheets of the whole city are stored in a database. Each fire station stores the fire acceptance information data table of each building in the corresponding responsible area. The data center of the fire department stores the fire protection acceptance information data table of the entire urban building, which can be stored in multi-level distribution according to the actual situation; and each individual system end downloads the fire protection acceptance information data table of the current building after receiving the fire alarm information. The individual soldier system end is local (you can also preset the fire protection acceptance information table of the building in the corresponding responsible area in advance, and call out the fire protection acceptance information data table of the current building after receiving the fire alarm information); The data interaction system at the end of the military system and the end of the command system, when a fire occurs or when the fire protection information of the building is updated, the system is responsible for downloading the data sheets of the building (or all buildings in the area under the responsibility of the fire department, depending on the needs) To the end of the individual soldier system; the on-site fire command system assists the on-site commander to check the location of the firefighters on each floor and the information of the surrounding fire facilities. Then command the firefighters through the voice system. Before going to the fire scene, the fire inspection and acceptance information database of the on-site fire command system needs to synchronize data with the database of the above-mentioned fire department data center to obtain the latest fire inspection and acceptance information data of urban buildings; the fire department data center deploys two IBM System x3850 X5 servers, one of which is used as the main server, and the other is used as a backup server, which stores a massive fire inspection and acceptance information database platform including buildings in the city or in a certain responsible area, and provides data services to relevant personnel of the fire department in real time , the two servers perform dual-machine hot backup to ensure high availability of data services.

Fire inspection and acceptance information data table: the content of the SQL data table of fire inspection and acceptance information for each building is as follows:

The various data information in Table 1-1 are obtained during fire acceptance. It contains all fire related equipment information in this building.

In Table 1-1, the fire protection item refers to the items related to fire emergency rescue in the fire acceptance; longitude refers to the longitude of the current location; latitude refers to the latitude of the current location; the east-west distance refers to the east-west distance of the current location relative to the southwest corner of the building The distance in the direction, the east is a positive value, the west is a negative value, and the unit is meters; the north-south distance refers to the distance in the north-south direction relative to the southwest corner of the building, the north is a positive value, and the south is a negative value, and the unit is m; floor refers to the number of floors where the current fire-fighting item is located; detailed description refers to other explanatory information on the fire-fighting item, which is beneficial to the work of firefighters in fire-fighting emergency rescue.

Table 1-1 lists nearly 30 types of fire protection items, each fire protection item has one or more devices, and each device is listed in the data sheet. For example, for a certain building, there are several fire hydrants, and the fire acceptance information data table contains all fire hydrant information in the building, and numbers are used to distinguish different fire hydrants. In practice, the items in the data table depend on the actual setting of each building, and additions and deletions are made on the basis of Table 1-1.

As shown in Figure 1, the individual soldier system consists of three parts, namely the real-time position awareness system, the voice system, and the plane display system. The individual system side can be realized by customizing and adding corresponding software and hardware modules on the basis of the existing tablet computer. The hardware part of the real-time position awareness system needs to add GPS, RFID three-dimensional positioning hardware modules or other three-dimensional positioning chips on the basis of the existing tablet computer hardware, and the current longitude, latitude, and altitude of firefighters can be obtained through the real-time position awareness system; The hardware part can directly use the existing voice input and output module of the tablet computer, and the voice system can play the real-time location information of firefighters and the information of firefighting facilities around the firefighters; the hardware part of the plane display system directly uses the existing display module of the tablet computer, The plane display system displays the current location of the firefighters and the location of the surrounding fire facilities in real time; the real-time location comparison system runs directly on the existing tablet computer, and compares the received 3D information with the standard data in the current building fire acceptance information data sheet Then transmit the location of the firefighters and surrounding fire facilities to the voice system and the flat panel display system. The floor input of firefighters needs to add a counter module on the basis of the current tablet motherboard hardware. Firefighters press the increase button every time they go up a floor, and press the down button every time they go down; A button is added to the hardware of the tablet computer motherboard. Press this button and the system can obtain and respond to the needs of firefighters' active position awareness.

The current building fire acceptance information form refers to the fire acceptance information form of the current building or multiple fire buildings. After a fire breaks out or building information is updated, the soldier system downloads to the local soldier terminal through the interactive system between the soldier terminal and the command terminal; the real-time position awareness system perceives the longitude, latitude, Height (related to the floor), and transmit the current location information of the firefighters to the real-time location comparison system at a certain interval; The voice system can communicate with the on-site fire commander; the plane display system will display the floor plan of the floor after the firefighters enter a certain floor, and display the location of all fire-fighting facilities on the floor on the floor plan. According to the return result of the real-time position comparison system, the current position of the firefighters will be displayed on the plan in real time, and displayed in conjunction with the voice system; the real-time position comparison system will obtain the current position of the firefighters and the benchmark in the fire acceptance information data table The data is compared to analyze the position of the firefighter in the building and the information of the fire-fighting facilities around the current location; the firefighter's active location awareness means that the firefighter actively presses the location-aware button. There is a certain time interval for information broadcasting. Through active location awareness, firefighters can actively obtain the information they need; firefighter floor input provides another simple and economical method for firefighters to obtain current floor information in addition to RFID. The operator manually presses the floor increase button every time he goes up a floor, and manually presses the floor decrease button every time he goes down a floor.

Real-time location awareness system: After the firefighters enter the building, the real-time location awareness system senses the current real-time location of the firefighters and transmits it to the real-time location comparison system. Firstly, the real-time position awareness method of firefighters is described by combining GPS and RFID technology. The longitude and latitude information is obtained and stored in the corresponding storage module through the GPS module in the firefighting navigation device carried by the firefighters, and the current latitude and longitude information is transmitted to the real-time position comparison system every 1 second (the interval can be set). Floor information is obtained using RFID identification technology, as shown in Figure 2:

As shown in Figure 2, to obtain the current floor information, it is necessary to install RFID electronic tags for the building, and a unique electronic code is stored in each tag. Install RFID electronic tags at every place that can lead to the upper or lower floor. In order to obtain the current floor information more conveniently, RFID electronic tags can also be installed in corridors and important places in the building. The RFID reader is integrated in the navigation device carried by the firefighters, and the label stores the mapping table between the floor and the electronic code of the RFID electronic tag. When the RFID reader is close to the floor identification equipment, it will read the RFID electronic code of the current floor in a non-contact manner, and obtain the current floor number according to the mapping table between the floor and the electronic code of the RFID electronic tag, and send it to the firefighters through the voice system Broadcast the current floor and transmit the currently obtained floor information to the real-time position comparison system. Here above, RFID is used as an example to describe how to obtain floor information, which can be obtained by firefighters manually inputting floor information.

For the real-time position awareness system, the combination of GPS and geomagnetic navigation or the addition of wireless transceiver modules at the individual terminal and the command terminal can also be used to locate the current position (longitude, latitude, altitude) of firefighters. For the positioning method combining GPS and geomagnetic: GPS and as a reference positioning; the inertial geomagnetic navigation module includes a three-axis earth magnetic field sensor, a three-axis gyroscope, a three-axis acceleration sensor, and an accurate altimeter. Firefighters mainly rely on inertial geomagnetic navigation modules for positioning in buildings. The combined navigation technology of geomagnetic navigation and inertial navigation can improve the overall performance of the navigation system and effectively improve the long-term accuracy of the simple inertial navigation system. For the wireless transceiver positioning method: add wireless transceiver modules on the individual soldier terminal and command terminal respectively. The wireless transceiver module includes a wireless transceiver chip and a power amplifier circuit, and its hardware can be realized by adding Chipcon's CC1000 wireless transceiver chip to the motherboard of the existing tablet computer. In addition, wireless signal transceiver devices need to be placed around the fire building. After the firefighters enter the fire scene, the wireless transceiver module at the command end sends wireless signals to the signal receiving devices placed in different positions around the fire field, and uses the TDOA (Time Difference of Arrival) positioning algorithm to realize the positioning of the firefighters' current location.

Real-time location comparison system: The real-time location comparison system compares the longitude, latitude, and floor information obtained from the real-time location awareness system with the benchmark fire inspection and acceptance information data table, and obtains the information of fire facilities within the preset range. The specific process of real-time position comparison is shown in Figure 3:

As shown in Figure 3, after the real-time position comparison system obtains the longitude, latitude, and floor information identifying the firefighter's current location, it reads the preset plane scanning radius, and then searches the current floor in the fire acceptance information data table. The information of the fire facilities within the preset scanning radius from the current position, and through the voice system every 15 seconds (the interval can be set), if the firefighters broadcast the current location and the surrounding fire facilities information to the firefighters. If the firefighter has previously selected to obtain a particular type of fire facility, the voice system will only play the current location and such selected fire facility information. For example, if the firefighter selects to only receive foam generator information, the voice system will only broadcast the foam generator information within the preset scanning radius of the current location. At the same time, in order to make the firefighters more intuitively understand the current location and surrounding environment information, the obtained firefighting facility information can be transmitted to the display system of the individual system navigation device, and the display system will display the firefighter's position in the current floor plan in real time. And it can cooperate with the voice system to broadcast and display the information of fire protection facilities currently being broadcast.

Taking the location of indoor fire hydrant 002 as an example, the process of real-time location comparison is as follows:

1. Read the floor information of the firefighters in 2), assuming that the read floor number is 3, that is, the firefighters are currently located on the third floor of the building, and the real-time comparison system uses the SQL database table of the fire acceptance information data of the current building Select all fire facilities with floor number 3.

2. Read the latitude and longitude information of firefighters in 2), that is, the current horizontal position information of firefighters, and judge the distance between the current latitude and longitude location point and the firefighting equipment latitude and longitude location point with floor number 3. Generate a new temporary SQL data table, the data table includes the following columns: fire item, longitude, latitude, detailed description, current distance. The "current distance" is the distance between the latitude and longitude position point and the latitude and longitude position point of each firefighting equipment with the floor number 3.

3. Read the preset scanning radius r, if the distance range calculated in step 2 is less than r, then select the rows of these fire facilities that meet the conditions from the temporary SQL data table generated in step 2. Generate a new temporary SQL data table.

4. Select the corresponding category of equipment sequentially or according to the input of the firefighter button, read the fire-fighting items, current distance, and detailed description information of each fire-fighting facility in the new temporary SQL data table generated in step 3, and pass them to the plane display system and voice system .

Plane display system: refers to a system that displays the current location of firefighters and surrounding fire facilities in real time. Specifically as shown in Figure 4: when the firefighters enter a certain floor, the display system reads the corresponding floor plan, and compares the real-time position with the relative position information of the current position obtained by the system on the plan in real time (excluding floor information) It will be displayed on the screen, and at the same time, the information of the fire facilities within the preset scanning radius of the current position will be highlighted. When the voice system broadcasts, the plane display system cooperates with flashing display.

Active location awareness for firefighters: when firefighters manually press the sensing button, the real-time location awareness system immediately transmits the current longitude, latitude, and floor information to the real-time location comparison system. After the comparison, the current location and the surrounding fire facilities information will be broadcast to the firefighters through the voice system according to the choice of the firefighters.

As shown in Figure 1, the overall structure of the system is described as follows:

When the fire protection acceptance of the building is completed or when the building is redecorated, it is not only necessary to fill in the 12 fire protection acceptance data sheets during the corresponding acceptance process, but also generate or update the SQL fire protection acceptance information data sheet of the building at the same time. This SQL data table contains the information required in the corresponding fire emergency, such as fire items, longitude, latitude, floor, and detailed description. The SQL database of the data center of the fire department stores multiple SQL fire inspection and acceptance information data sheets for the entire city or within a certain area of responsibility. Before going to the fire scene, the fire inspection and acceptance information database of the on-site fire command system needs to synchronize data with the database of the fire department data center to obtain the latest fire inspection and acceptance information data of urban buildings; The fire acceptance information data sheets of all buildings in the area shall be updated in time.

After a fire breaks out in a certain building, the equipment at the individual soldier system side updates and downloads the fire protection acceptance information data table of the current building or building group in the fire protection acceptance information data table to the individual soldier system through the interactive system between the individual soldier terminal and the command terminal, and The table generates floor plans for each floor. If the individual soldier system end device already has the latest SQL data table of the current fire building, it does not need to be downloaded repeatedly. After firefighters equip individual system end equipment and enter the building fire scene, the real-time location awareness system obtains the firefighters' current latitude and longitude information through positioning technology, and obtains the firefighters' current floor information through the floor perception module such as RFID. The display system in the equipment calls out the floor plan according to the current floor information, and the location of each fire-fighting facility in the current floor is marked on the floor plan. The real-time location awareness system transmits the real-time latitude and longitude and floor information to the real-time location comparison system. The real-time position comparison system reads the local current building fire acceptance information table at the individual soldier system end, selects the fire-fighting facility information data line of the current floor, and selects the firefighter's position within the preset range according to the preset distance range. The fire-fighting facilities broadcast the results to the firefighters through the voice system, and at the same time transmit them to the display system in real time and display them through the display system. When the voice system broadcasts a certain device, the display system displays it with flashing. The real-time location awareness system will also transmit the real-time location information of firefighters, including longitude, latitude, and floor, to the individual soldier and command terminal system through the wireless communication network. Based on the location information of each firefighter, surrounding firefighting facilities, and other information about the building, the on-site commander will provide more targeted guidance on fire scene rescue through the voice system. Firefighters can also use the firefighter's active location awareness button to send a request for obtaining information about the current location and surrounding firefighting facilities.

The examples described above have described in detail the implementation of each part of the present invention, but the specific implementation form of the present invention is not limited thereto, for those of ordinary skill in the art, without departing from the description of the present invention Various obvious changes made thereto within the spirit of the method and the scope of the claims are within the protection scope of the present invention.
