Detailed ways

The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

Embodiment one

Fig. 1 is a flow chart of a method for measuring the floor height of an elevator provided in Embodiment 1 of the present invention. This embodiment is applicable to the situation of measuring the floor height according to the elevator, and the method can be performed by an elevator floor height measuring device. It can be realized by means of software and/or hardware, and integrated in the elevator floor height measurement equipment. Further, the elevator floor height measurement equipment can be smart devices such as mobile phones, notebook computers, and elevator maintenance terminals.

Specifically, the elevator floor height measurement device can also be called a feature recognition device, which can be installed on the elevator to identify the target reference object in the elevator passage. At the same time, the elevator floor height measurement equipment is connected with the main control equipment of the elevator, so as to realize the measurement of the floor height through data interaction with the main control equipment after the target reference object is recognized. Wherein, the elevator channel is the channel for the elevator to run up and down, and the main control device is the device for controlling the elevator to run up and down to the target floor.

Referring to Fig. 1, the method specifically includes the following steps:

S110. Acquiring feature information of the target reference object currently collected by the feature sensor during the running process of the elevator.

Wherein, the target reference object is located in an elevator passage on a set floor of the target building, and the feature sensor is located at a set position of the elevator. Specifically, the target reference object is a marker located in the elevator passage for measuring the floor height, which is easy to identify. Further, each floor is equipped with a target reference object, and the target reference objects on each floor may be the same or different. Similarly, the specific installation positions of the target reference objects on different floors may be the same or different. Specifically, in order to facilitate the identification of the target reference objects, in the embodiment, the target reference objects on each floor are set to be the same, and the installation positions are relatively fixed, that is, each target reference object is installed at the same position on the corresponding floor. Further, the target reference object can be the extended hall door sill of the elevator hall door, the hall door pulley or the toe guard of the hall door, or the hall door lock, etc. The specific choice of which one as the target reference object can be based on actual needs setting, which is not limited in this embodiment. Further, the set floors may be some floors of the target building, or all floors. Among them, some floors can be set according to the actual situation. For example, some floors may be floors other than the highest floor, floors other than the lowest floor, or floors other than the highest floor and the lowest floor, which one can be selected according to actual needs. For example, if the elevator floor height measurement equipment is installed on the upper end of the elevator car, and the target reference object is located at the position corresponding to the lower end of the elevator car when the elevator stops on each floor, then when the elevator stops at the lowest floor, it cannot If the target reference object corresponding to the lowest floor is detected, at this time, it can be set that the target reference object is arranged on a floor other than the lowest floor.

Feature information is information representing features of a reference object. Generally, the feature information of different reference objects is quite different, therefore, the target reference object can be identified according to the feature information. For example, the feature information may be the outline, structure, color, etc. of the target reference object.

Feature sensors are sensors used to collect feature information, and different sensors are selected according to different collection methods. Wherein, the specific installation position of the characteristic sensor can be set according to actual needs. For example, the target reference object is the hall door pulley, and when the outline of the hall door pulley is used as the feature information, the outline of the hall door pulley can be obtained based on video recognition technology. At this time, the camera can be selected as the feature sensor. Wherein, how to recognize the outline of the hall door pulley based on the video recognition technology is not limited here. Another example is that the target reference object can also be an extended hall door sill. At this time, the difference between the distance between the characteristic sensor and the extended hall door sill and the distance between the characteristic sensor and the elevator passage wall can be selected as the characteristic information, based on Millimeter wave, infrared and other distance measurement technology, measure the distance from the characteristic sensor to the wall of the elevator passage and the distance between the characteristic sensor and the extended hall door sill, and identify the extended hall door sill according to the distance.

When the elevator moves up and down, when the extended hall door sill is not encountered, the characteristic sensor measures the distance L0 from itself to the wall of the elevator passage, and when it encounters the extended hall door sill, the characteristic sensor measures the The distance L1 between itself and the extended hall door sill, when leaving the extended hall door sill, what the characteristic sensor measures is the distance L2 between itself and the wall of the elevator passage. When the difference between the two distances is within a certain range, and the characteristic sensor measures the distance L1 between itself and the extended hall door sill for a certain period of time, it indicates that the extended hall door sill is recognized.

S120. Confirm the height information of the target reference object according to the feature information.

The height information refers to the distance from the target reference object to the bottom end of the elevator passage. In general, an elevator has a position device such as a scale for measuring height. One end of the ruler is located at the bottom end of the elevator passage, and the other end is connected with the car. When the elevator is running upwards, the ruler can measure the height of objects in the elevator passage in real time. Taking the magnetic scale as an example, during the operation of the elevator, when the characteristic information collected by the characteristic sensor is the characteristic information of the target reference object, the elevator floor height measuring device sends a signal to the main control device to make the main control device read the magnetic grid The height information measured by the ruler is sent to the elevator floor height measuring device, and the elevator floor height measuring device records and stores the height information sent by the master control device. Wherein, the specific corresponding relationship between the target reference object and its corresponding specific floor is not limited in this embodiment. For example, the corresponding relationship between the target reference object and its corresponding specific floor may be pre-stored in the master control device. When the target reference object on the third floor is identified, the master control device can send the position information of the third floor to the elevator floor height measuring device at the same time. For another example, if the number of target reference objects and the floors on which they are distributed are determined in advance, then, during the operation of the elevator, the corresponding floors can be determined according to the recognition sequence of the target reference objects. For example, if the target building has 3 floors, and each floor is set with a target reference object, then when the elevator runs from bottom to top, it can be determined that the first recognized target building corresponds to 1 floor, and the second recognized target building Objects correspond to 2 layers, and so on.

Further, the elevator floor height measuring device also includes an immediate button. The immediate button is used to save the current height information when the target reference object is abnormal and cannot be recognized, so as not to obtain the height information of the current layer target reference object. For example, when the target reference object is incomplete or damaged, the feature sensor cannot collect the feature information of the target reference object, resulting in the failure to recognize the target reference object. At this time, the inspector or the elevator floor height measurement device presses the immediate button, the main control device immediately reads the height information of the scale and sends it to the elevator floor height measurement device, and the elevator floor height measurement device confirms the currently received height information It is the height information of the target reference object, and it will be saved immediately. The immediate button can also be used to save the height information when the target reference object cannot be recognized due to the different specific installation positions of the elevator floor height measuring equipment. For example, in practical applications, when the elevator floor height measuring equipment is installed in the car, it is impossible to identify the target reference object on the lowest floor located on the level floor. At this time, you can press the button immediately to save the height information of the lowest level.

S130. Calculate the relative floor height of the current floor according to the height information and historical height information.

Wherein, the historical height information is the height information of the historical target reference object collected by the characteristic sensor, the current floor refers to the floor for which the relative floor height can be determined at present, and the relative floor height refers to the upper and lower leveling positions of the current floor height between. In the embodiment, the current floor can be set as the floor except the highest floor in the target building.

Exemplarily, the relative story height of the 3rd floor refers to the distance between the upper and lower leveling floors of the 3rd floor, wherein the lower leveling floor can be considered as the upper leveling floor of the 2nd floor, and the upper leveling floor can be regarded as the lower leveling floor of the 4th floor. Since there will be a target reference object on each floor, during the operation of the elevator, every time a target reference object on a floor is identified, a height information will be stored, which will be recorded as the height information of the historical target reference object. According to the current height information and The difference of the historical height information can calculate the relative height of the current floor. Wherein, the historical altitude information is preferably the latest stored historical altitude information compared with the currently acquired altitude information. For example, the height information corresponding to the target reference object on the 3rd floor of the current floor recognized by the elevator floor height measuring equipment is D3, and the stored historical height information of the 2nd floor is D2, then the relative floor height of the 2nd floor is the difference between D3 and D2 . At this time, when the elevator runs from the target reference object on the 2nd floor to the target reference object on the 3rd floor, its running distance is equal to the relative floor height of the 2nd floor.

Specifically, the elevator floor height measuring device can be placed in the car, and at this time, the car door needs to be bypassed to open the car door to ensure the normal operation of the elevator floor height measuring device. Further, the elevator floor height measurement device also includes a start button. When the start button is pressed, the device enters the recognition mode and waits for the elevator to start running in a maintenance mode.

In the method for measuring the floor height of an elevator provided by Embodiment 1 of the present invention, during the operation of the elevator, the characteristic information of the target reference object currently collected by the characteristic sensor is obtained, and the height information of the target reference object is confirmed according to the characteristic information. According to the height information and historical height information, the relative floor height of the current floor is calculated, and the automatic measurement of the floor height is realized. During the operation of the elevator, the relative floor height can be determined based on the height information of the target reference object on each floor, without the need for The leveling sensor is set, and there is no need for the elevator to stop at each floor of the target floor. The relative floor height can only be obtained after confirmation by the on-site personnel, which improves the accuracy and efficiency of floor height measurement.

Embodiment two

Fig. 2 is the flow chart of a kind of elevator floor height measurement method that the embodiment of the present invention provides, and present embodiment is optimized on the basis of above-mentioned embodiment, with reference to Fig. 2, this method specifically comprises the following steps:

S210. Construct a sample set of known target reference objects.

The known target reference object is a reference object set in advance for measuring the floor height, such as a hall door pulley, or an extended hall door sill. The sample set is a collection including various known target reference objects and feature information of each known target reference object. The purpose of constructing the sample set is to learn the characteristics of known target reference objects, so as to improve the accuracy of judgment of target reference objects, and then improve the accuracy of floor height judgment.

S220. Perform feature learning on the sample set to determine feature information of the known target reference object.

In this embodiment, the specific algorithm for feature learning of the sample set is not limited. The purpose of the learning is to summarize the feature information of each type of known target reference objects, so as to provide more accurate basis for the identification of subsequent target reference objects. Exemplarily, a typical artificial neural network learning method can be used to establish a neural network model to complete the learning of the characteristics of the sample set.

S230. Acquire object feature information currently collected by the feature sensor during the running of the elevator.

The object characteristic information is the characteristic information of all objects that can be identified by the characteristic sensor in the elevator passage. In addition to the target reference object, there are also non-target reference objects in the elevator passage. During the operation of the elevator, the characteristic information of the object collected by the characteristic sensor includes both The characteristic information of the target reference object also includes the characteristic information of the non-target reference object. For example, the target reference object is the hall door pulley, and the feature information is specifically the outline of the hall door pulley. In addition to the hall door pulley, there are extended hall door sills, hall door locks and other devices in the elevator passage. During the operation of the elevator, the feature sensor In addition to the contours of the hall door pulleys, the contours of devices such as extended hall door sills or hall door locks are also recorded.

S240. Determine whether the feature information of the object matches the feature information of the known target reference object. If the feature information of the object matches the feature information of the known target reference object, perform S250. If the feature information of the object If it does not match the feature information of the known target reference object, return to S230.

In order to accurately determine the position of the target reference object, it is necessary to identify the target reference object first. Therefore, it is necessary to match the feature information of the object collected by the feature sensor with the feature information of the known target reference object to identify the target reference object. If the matching is successful, execute S250 to determine the feature information of the object as the feature information of the target reference object. If the matching is unsuccessful, it means that the feature information collected by the feature sensor belongs to the feature information of the non-target reference object. At this time, you can return Execute S230 to continue acquiring object feature information collected by the feature sensor.

S250. Determine the feature information of the object as feature information of a target reference object.

If the object characteristic information matches the characteristic information of the known target reference object, it means that the object corresponding to the characteristic information is the target reference object, and the object characteristic information is determined as the characteristic information of the target reference object.

S260. Send the characteristic information to the main control device of the elevator, so as to instruct the main control device to read the height information of the scale.

The elevator floor height measurement device can communicate with the main control device through the communication interface. After the elevator floor height measurement device recognizes and confirms the target reference object, it communicates with the main control device through the communication interface to notify the main control device that the target has been recognized Reference object, at this time, after receiving the communication signal, the main control device immediately reads the height information of the scale (such as a magnetic scale), that is, the main control device determines the height information corresponding to the current target reference object.

S270. Acquire the altitude information fed back by the master control device.

After the master control device reads the height information of the ruler, it will feed back to the elevator floor height measuring device through the communication interface, and the elevator floor height measuring device confirms the height information of the current target reference object.

S280. Calculate the relative floor height of the current floor according to the height information and historical height information.

S290. Send the relative floor height to the main control device of the elevator.

After the floor height measurement is completed, the relative floor height is sent to the main control device of the elevator, and the main control device can obtain the floor height of each floor and store the relative floor height of each floor for subsequent use. For example, it is used to generate the speed curve of elevator operation.

In the elevator floor height measurement method provided by Embodiment 2 of the present invention, before obtaining the feature information of the target reference object currently collected by the feature sensor, a sample set of known target reference objects is firstly constructed, and by learning the sample set, it is determined that Know the characteristic information of the target reference object, and identify the target reference object according to the characteristic information, and then obtain the height information corresponding to the target reference object through the main control device, so that the automatic identification of the target reference object is realized during the operation of the elevator , and improve the accuracy of the judgment of the target reference object, and provide a basis for the determination of the storey height.

On the basis of the above embodiments, S280 specifically includes: calculating the relative height of the current floor according to the height reference information, the height information and historical height information.

Wherein, the height reference information is the flat height information of the lowest layer and/or the flat height information of the highest layer.

Wherein, the lowest floor refers to the lowest floor among the floors of the target building. Generally, if there is no negative floor, the first floor above the ground is considered to be the lowest floor. The leveling floor refers to the parking floor of the elevator on each floor. At this time, the car sill and the hall door sill are on the same level to ensure the normal opening and closing of the elevator door. Leveling height information refers to the distance from the hall door sill to the bottom end of the elevator passage when the elevator reaches the leveling floor. Specifically, when the elevator floor height measuring device is placed in the car, the leveling floor height information can be obtained by pressing a button immediately.

Specifically, since the setting position of the target reference object is not fixed, when the elevator is at the lowest floor, the position confirmed based on the target reference object is not the position information of the hall door sill. The lowest position at that time, that is, the leveling height information of the lowest layer. In practical applications, the lowest end of the elevator running passage may be lower than the hall door sill of the lowest floor. If the leveling height information of the lowest floor cannot be determined, the calculation of the floor height will be inaccurate. At the same time, since there may be restrictions on the setting position of the target reference object on the highest floor, if the target reference object cannot be set on the highest floor, then, when calculating the relative height of the next high floor, when the elevator stays at the top floor, pass Immediately press the button to save the leveling height information of the highest level, and then combine the leveling height information of the lowest level and/or the leveling height information of the highest level to confirm the relative height. Taking the target building with 4 floors as an example, and the target reference object is set on the upper side of the hall door of each floor, the elevator floor height measurement equipment can obtain the height information of the target reference object on the third floor and the leveling height information on the fourth floor. , according to the difference between the leveling height information of the 4th floor and the height information of the target reference object of the 3rd floor and the difference between the historical height information of the target reference object of the 1st floor and the leveling height information of the 1st floor, the 3rd floor can be calculated relative layer height.

Another situation is that when the target reference objects are set at the hall door sills of each floor, and the elevator floor height measuring equipment is placed on the car roof, the hall door sills of the lowest floor cannot be identified. At this time, you can press the key immediately to save the height information when the elevator stops at the lowest floor and the height information when the elevator reaches the second floor leveling floor, and then determine the minimum The relative height of the layer.

Embodiment three

Fig. 3 is a flow chart of a method for measuring elevator floor height provided by Embodiment 3 of the present invention. This embodiment is embodied on the basis of the foregoing embodiments. With reference to Fig. 3, the method specifically includes the following steps:

S310. Obtain basic configuration data of the elevator.

Wherein, the basic configuration data includes the total floor of the target building. The number of total floors of the target building is pre-stored in the main control device of the elevator. Before the elevator runs, the elevator floor height measuring device communicates with the main control device of the elevator through the communication interface to obtain the number of total floors of the target building. The elevator floor height measuring device compares the number of relative floor heights currently obtained with the number of total floors to determine whether the elevator needs to continue running. S320. During the running of the elevator, acquire feature information of the target reference object currently collected by the feature sensor.

S330. Confirm the height information of the target reference object according to the feature information.

S340. Calculate the relative floor height of the current floor according to the height information and historical height information.

S350. Count the currently obtained relative storey heights.

The elevator floor height measurement equipment will store the specific height information corresponding to the target reference object every time it recognizes the target reference object of a floor, calculate the relative floor height of each floor according to the specific height information of the target reference object, and count the number of relative floor heights, Get the current relative layer height.

S360. Determine whether the number is equal to the total number of floors. If the number is equal to the total number of floors, execute S370; otherwise, execute S320.

Whether the elevator needs to continue running can be determined according to the currently obtained number of relative storey heights and the total number of floors. Specifically, if the number is equal to the number of total floors, then execute S370 to confirm that the elevator has run completely; if the number is not equal to the number of total floors, it means that there is still a floor height to be measured, and the elevator needs to continue running, and execute S320 , until the current number of relative storey heights is equal to the number of total floors.

It should be noted that if the highest floor cannot be calculated through the height information, then, at this time, it can be determined whether the difference between the number and the total number of floors is 1, and if it is 1, it is confirmed whether it is necessary to obtain the level height information of the highest floor , if not needed, execute S370, otherwise, when the elevator runs to the highest level, obtain the height information of the highest level, and then execute S370.

S370. Confirm that the elevator has run completely.

It should be noted that, in practical applications, if the current floor is the highest floor, and the target reference object cannot be set at a position higher than the highest floor in the elevator passage. In this case, the relative height of the highest floor cannot be calculated. In view of this, it is also set in the embodiment: the current floor includes the middle floor and the lowest floor, the basic configuration data includes the total height of the elevator passage of the target building, and the total height is the hall door sill to the lowest floor. The height between the top floors of the highest level. At this time, after the elevator floor height measuring device calculates the relative floor height of the current floor according to the height information and historical height information, it also includes:

The relative height of the highest floor is determined according to the relative height of the current floor and the total height.

Specifically, since the relative floor heights of other floors except the highest floor have been determined, the relative floor height of the highest floor can be obtained by subtracting the relative floor heights of other floors from the total height.

Optionally, based on the installation location of the elevator floor height measurement device, the height information of the specific target reference object collected by it will also be different. The calculation method of the relative floor height of each floor will be further illustrated through specific examples below.

FIG. 4 is a schematic diagram of a hall door pulley as a target reference object provided by Embodiment 3 of the present invention. Referring to Fig. 4, the hall door pulley S1 is arranged on the top of the hall door, the hall door sill is at the bottom of the hall door, and the hall door is in the middle. When the elevator is running, a corresponding height information can be obtained every time the hall door pulley is recognized.

Fig. 5 is a schematic diagram of measuring the first height information of a target reference object. Specifically, the elevator floor height measurement equipment is installed in the car, the target reference object is set with reference to Figure 4, the total number of floors of the target building is 4 floors, and the elevator starts to run upwards from the first floor as an example. The total height of the elevator passage is set as H. Referring to Figure 5, D0 is the leveling height information of the 1st floor, D1, D2 and D3 are the height information corresponding to the hall door pulleys on the 1st, 2nd and 3rd floors identified by the elevator floor height measuring equipment, and D4 is the height information of the 4th floor level height information. When the elevator is on the first floor, the elevator floor height measurement device can obtain the value of D0 through the main control device. When leveling, obtain the value of D4 through the master control device. According to D0, D1, D2, D3 and D4, the relative height of each layer can be calculated. Specifically, the relative height of the first floor H1=D2-D1, the relative height of the second floor H2=D3-D2, the relative height of the third floor H3=(D4-D3)+(D1-D0), where D4 -D3 is the relative height from the hall door pulley on the 4th floor to the 3rd floor, and D1-D0 is the relative height from the hall door pulley on the 1st floor to the leveling floor on the 1st floor. Since the hall door pulley on the 4th floor cannot be identified, the hall door pulley on the 4th floor The corresponding height information cannot be obtained. Therefore, the relative height of the 3rd floor needs to be calculated with the help of the leveling height information D0 of the 1st floor. The relative height of the 4th floor is based on the total height and the calculated relative height of the current floor. The difference is obtained, that is, H4=H-H1-H2-H3.

FIG. 6 is a schematic diagram of an extended landing sill provided as a target reference object according to Embodiment 3 of the present invention. Fig. 7 is a schematic diagram of measuring the second height information of the target reference object. Taking the elevator floor height measurement equipment installed on the car roof, the target reference object is set with reference to Figure 6, the total number of floors of the target building is 4 floors, and the elevator starts to run upwards from the 1st floor as an example, the total height of the elevator passage is set as H. The specific identification process is similar to that where the target reference object is the hall door pulley, and will not be repeated here. Referring to Figure 7, D0 is the height information saved by pressing the button immediately when the elevator stops on the 1st floor, D2 is the height information saved by pressing the button immediately when the elevator reaches the 2nd floor, and D1, D3 and D4 are the 2nd and 3rd floors respectively Based on the height information corresponding to the hall door sill S2 extended on the 4th floor, the relative height of each floor can be calculated according to D0, D1, D2, D3 and D4. Specifically, the relative height of the first floor H1=D2-D0, the relative height of the second floor H2=D3-D1, the relative height of the third floor H3=D4-D3, the relative height of the fourth floor H4=H-H1 -H2-H3.

The method for measuring the floor height of an elevator provided by Embodiment 3 of the present invention is embodied on the basis of the above-mentioned embodiments. By obtaining the total floor and the total height, the efficiency of floor height measurement is improved, and the man-hours and work hours are reduced. quantity.
