Description

[Technical field]

[0001] The present invention relates to an elevator maintenance work support system and an elevator maintenance work support method. [Background technology]

[0002] When performing maintenance work on elevators and other lifts, workers may climb onto the top of the car and perform work inside the hoistway. Because such work inside the hoistway is high-altitude work, workers must wear a fall prevention device called a safety belt and hook the safety belt hook onto a designated place to prevent falls before performing the work. Basically, the use of a safety harness is mandatory when working at height in an elevator, but putting on the harness and fastening the hook are left to the worker.

[0003] Patent Document 1 describes a technology that detects when a safety belt is hooked and generates a contact signal, and outputs an alarm when a contact signal is not generated, thereby preventing workers from forgetting to use a safety belt when working at height. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2020-402 A Summary of the Invention [Problem to be solved by the invention]

[0005] According to the technology described in Patent Document 1, an alarm is outputted so that a worker can detect that he or she has forgotten to put on a safety belt, thereby preventing the worker from forgetting to put on the safety belt. However, in the technology described in Patent Document 1, the safety belt is configured to detect the hook and generate a contact signal, which poses the problem of requiring an expensive dedicated product. Also, in order for the hook of the safety belt to generate a contact signal, the safety belt needs to have a built-in power source, which can cause problems such as the safety belt not working properly when the battery runs out.

[0006] In view of the above, an object of the present invention is to provide an elevator maintenance work support system and an elevator maintenance work support method that enable high-altitude work on an elevator to be performed safely with a simple configuration. [Means for solving the problem]

[0007] In order to solve the above problems, for example, the configurations described in the claims are adopted. The present application includes multiple means for solving the above problems, and one example is an elevator maintenance work support system that is applied to an elevator maintenance work support system that includes a mobile terminal carried by a worker when performing elevator maintenance work, and a lighting device worn by the worker when performing elevator maintenance work. In terms of configuration, the lighting device includes a lighting detection sensor that detects when the lighting device is on, and a first communication unit that transmits a detection signal when the lighting detection sensor detects that the lighting device is on, and the mobile terminal includes a second communication unit that receives the detection signal transmitted from the first communication unit, and a warning processing unit that performs warning processing when the second communication unit receives the detection signal. Effect of the Invention

[0008] According to the present invention, with a simple configuration, when a worker performs work on an elevator, it is possible to reliably warn the worker whether safety measures have been taken, etc. That is, when working at high altitudes on an elevator, the work is performed in a dark place such as inside a hoistway, so it is necessary to turn on the lighting device. Then, by outputting a warning sound when it is detected that the lighting device is turned on, it is possible to reliably output a warning sound at the start of work. Therefore, according to the present invention, the warning sound can prompt the worker to take safety measures such as fastening the hook of the safety belt. Problems, configurations and effects other than those described above will become apparent from the following description of the embodiments. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An elevator maintenance work support system and an elevator maintenance work support method according to one embodiment of the present invention (hereinafter referred to as "this example") will be described below with reference to the accompanying drawings.

[0011] [System Overview] FIG. 1 is a diagram showing an outline of a process for performing maintenance work support in an elevator maintenance work support system according to this embodiment. A worker a who performs maintenance work on an elevator or other lifting machine wears a safety belt 90 around his / her waist and shoulders while working. The maintenance work here includes various tasks related to the elevator, such as inspection, repair, installation, and removal work. When worker A enters the elevator shaft or the like to perform work at height, he or she hooks the hook 91 attached to the safety belt 90 onto a hook attachment location such as the top of the elevator car and performs the work. In this way, in the unlikely event that worker A falls, he or she can be pulled up by the safety belt 90, preventing the occurrence of a fall accident.

[0012] Furthermore, when worker a enters an elevator or the like and performs work at a height on top of a car or the like, the worker wears a helmet 100 with a lighting device (headlight) 101 attached to the front on his / her head because the work location is a dark place. The lighting device 101 in this example is turned on by power from a battery 102 based on the operation of a switch (not shown). The lighting device 101 is provided with an illuminance sensor 103 (see FIG. 2) as a lighting detection sensor that detects the lighting of the lighting device 101 itself. The illuminance sensor 103 is provided beside the lighting device 101 of the helmet 100.

[0013] When the illuminance sensor 103 detects an illuminance level corresponding to the lighting device 101 being turned on, a communication unit 104 (FIG. 2) built into the lighting device 101 wirelessly transmits a detection signal. The detection signal is received by a mobile terminal 200 carried by the worker. The mobile terminal 200 is a communication device held by an elevator maintenance worker, and is configured, for example, as a smartphone or tablet terminal. A maintenance work support application program is installed in this mobile terminal 200, and during maintenance work, the worker a starts the corresponding maintenance work support application program to register the arrival at the work site and the start of the work.

[0014] The mobile terminal 200 outputs a warning sound when it receives a detection signal transmitted from the lighting device 101. For example, the mobile terminal 200 outputs a warning sound such as "Please fasten the hook of the safety belt before taking a picture." Having heard this warning sound, worker a hangs the hook 91 of the safety belt 90 on a predetermined hook attachment location, and then takes an image of the hook 91 with the image capturing unit 217 (FIG. 2) built into the mobile terminal 200.

[0015] When this image is captured, the mobile terminal 200 analyzes the captured image and transmits the captured image to a predetermined server 300 for storage. The server 300 is provided on a network to which the mobile terminal 200 can be connected via wireless communication. The captured images stored in the server 300 can be viewed on an administrator terminal 400 operated by an administrator who manages the maintenance work performed by the worker a.

[0016] [System configuration] FIG. 2 shows the configuration of the elevator maintenance work support system of this embodiment. A lighting device 101 that functions as a headlight is attached to a helmet 100, and the lighting device 101 is turned on by power from a battery 102 based on the operation of a switch (not shown). In addition, an illuminance sensor 103 and a communication unit (first communication unit) 104 are attached to the lighting device 101. The illuminance sensor 103 is disposed on the front side of the helmet 100 adjacent to the lighting device 101, and outputs a detection signal when it detects an illuminance equal to or greater than a predetermined threshold value corresponding to the lighting device 101 being turned on.

[0017] The detection signal output by the illuminance sensor 103 is supplied to a communication unit 104 . The communication unit 104 is a processing unit that performs short-range wireless communication such as Wi-Fi or Bluetooth (registered trademark), and transmits the detection signal obtained from the illuminance sensor 103 to the mobile terminal 200 wirelessly.

[0018] The mobile terminal 200 is a wireless communication terminal such as a smartphone. The mobile terminal 200 includes a communication unit (second communication unit) 211, an entrance / exit registration unit 212, an air pressure sensor 213, a memory unit 214, an air pressure data comparison unit 215, an audio output unit 216, an image capture unit 217, an image analysis unit 218, and an image transmission unit 219. These processing units 211 to 219 are configured in terms of functions required to execute the elevator maintenance work support system of this example.

[0019] The communication unit 211 receives a detection signal transmitted from the communication unit 104 included in the helmet 100. The detection signal received by the communication unit 104 is stored in the storage unit 214. The entrance / exit registration unit 212 performs registration processing when a worker enters and leaves a building in which an elevator on which maintenance work is being performed is installed. The air pressure sensor 213 measures the air pressure at the current location, and causes the storage unit 214 to store height information obtained from the measured air pressure value.

[0020] The atmospheric pressure data comparison unit 215 compares the altitude information based on the past atmospheric pressure data stored in the storage unit 214 with the current altitude information, and determines on what floor the worker carrying the mobile terminal 200 is located.

[0021] When a detection signal from the communication unit 104 of the helmet 100 is stored in the memory unit 214, the audio output unit 216 outputs a warning sound based on the floor determined by the air pressure data comparison unit 215. Here, the audio output unit 216 may output a warning sound such as an alarm sound, or may output warning words as a voice.

[0022] The image capturing unit 217 captures an image of the surroundings of the mobile terminal 200 in response to an operation by the operator a. The image captured by the image capturing unit 217 is supplied to the image analysis unit 218. The image analysis unit 218 determines whether or not the hook 91 of the safety belt 90 is present in the image captured by the image capture unit 217 through image analysis. If the hook 91 is not present in the image, the image analysis unit 218 causes the audio output unit 216 to continue outputting the alarm sound. Moreover, if the hook 91 is present in the image, the image analysis section 218 transmits the captured image from the image transmission section 219 to the server 300 .

[0023] The server 300 includes an image storage unit 301 and stores images transmitted from the mobile terminal 200 . The images stored in the image storage unit 301 of the server 300 can be viewed on the image viewing unit 401 of the administrator terminal 400 .

[0024] The mobile terminal 200 is an information processing terminal configured as a so-called computer, and has a hardware configuration shown in FIG. 3, for example. That is, as shown in FIG. 3, the computer serving as the mobile terminal 200 includes a CPU (Central Processing Unit) 201, a memory 202, a storage 203, a display / operation unit 204, a communication unit 211, an air pressure sensor 213, an audio output unit 216, and an image capturing unit 217, all of which are connected to a bus.

[0025] The CPU 201 is a processing unit that reads out program code of software that realizes the functions performed by the mobile terminal 200 from the memory 202 or the storage 203 and executes it. The CPU 201 reads out program codes from the memory 202 or the storage 203 and executes arithmetic processing in the work area of ​​the memory 202, thereby configuring various processing function units in the memory 202. That is, the memory 202 is configured with various processing units such as the atmospheric pressure data comparison unit 215 and the image analysis unit 218 shown in FIG.

[0026] A large-capacity information storage medium such as a semiconductor memory is used for the storage 203. The storage 203 stores an application program for supporting elevator maintenance work and data (such as image data) obtained by executing the program. The display / operation unit 204 displays characters and images, and also accepts operations by the worker who is the holder of the mobile terminal 200. The display / operation unit 204 is configured, for example, with a display panel equipped with a touch panel.

[0027] The communication unit 211 includes a short-range wireless communication processing unit such as Wi-Fi or Bluetooth, and a wireless communication processing unit that performs wireless communication with a base station for wireless telephones. The communication unit 211 also functions as the image transmission unit 219 shown in FIG. The image capturing unit 217 captures still images or moving images in response to an operation on the display / operation unit 204 . The air pressure sensor 213 detects air pressure. The air pressure detected by the air pressure sensor 213 is converted into altitude information by calculation in the CPU 201. The audio output unit 216 outputs voice, an alarm sound, and the like.

[0028] [Elevator maintenance work flow] 4 and 5 are flowcharts showing the flow of the support process when a worker a performs maintenance work on an elevator in the elevator maintenance work support system of this example. A and B in FIG. 4 are connected to A and B in FIG. 5, respectively. 4 and 5, steps S11 to S28 are operations performed by the worker a, and steps S101 to S102 are processes in the lighting device 101 mounted on the helmet 100. Also, in Fig. 4 and 5, steps S201 to S220 are processes in the mobile terminal 200, and steps S301 to S302 are processes in the server 300 or the administrator terminal 400.

[0029] 4, worker a enters a building where he / she is to perform work and registers the fact that he / she entered the building on the mobile terminal 200 (step S11). When worker a executes the registration operation, the entrance / exit registration unit 212 of the mobile terminal 200 is started (step S201), and the entry of worker a into the building is registered (step S202).

[0030] Following the entry registration, the mobile terminal 200 automatically activates the air pressure sensor 213 (step S203). The mobile terminal 200 calculates the height from the air pressure acquired by the air pressure sensor 213 during this automatic activation, and stores the calculated height as "height information H1" in the storage unit 214 (step S204).

[0031] Returning to the explanation of the process performed by the worker a, after entering the building in step S11, the worker a starts the elevator inspection work (step S12). At this time, the worker a also greets the building manager. Then, the worker a gets into the elevator car of the elevator to be inspected and attaches a "under inspection" tag to the landing of each floor (step S13). Furthermore, the worker a stops the car at a floor other than the lowest floor (step S14). In this state, the worker a operates the in-car operating switch to switch the elevator's operation mode to maintenance mode (step S15). After that, the worker a gets off the car at the landing (step S16). Then, the worker a performs a setup operation to lower the car to a position where the worker a can get on the car (step S17). After the car has been lowered, the worker a opens the landing door with the outside opening key (step S18).

[0032] In this state, the worker a turns on the lighting device 101 of the helmet 100 and visually checks the position of the car (step S19). The lighting device 101 of the helmet 100 is turned on by the lighting operation of the worker a (step S101). Then, the illuminance sensor 103 attached to the lighting device 101 performs a lighting detection process to detect light, and the communication unit 104 performs a transmission process to transmit a detection signal (step S102).

[0033] 5, the worker a fully opens the landing door (step S20), and then the worker a gets on top of the elevator car (step S21). While worker a has been working up to this point, in the mobile terminal 200 carried by worker a, the communication unit 211 performs a reception process for receiving a detection signal (step S211), and the air pressure sensor 213 is activated (step S212). Then, in the mobile terminal 200, the current height is calculated from the air pressure obtained by the activated air pressure sensor 213, and the calculated "height information H2" is stored in the storage unit 214 (step S213).

[0034] After that, the atmospheric pressure data comparison unit 215 compares the "height information H1" and the "height information H2" stored in the storage unit 214, and determines that there is a predetermined difference (step S214). Here, it is determined that there is a difference in height of at least one floor. If there is a difference in height of at least one floor in step S214, it means that worker a has boarded the elevator car on a floor (second floor or higher) that is at least one floor higher than the building entrance floor (for example, the first floor).

[0035] When it is determined in step S214 that the worker a has climbed onto the car, the audio output unit 216 of the mobile terminal 200 outputs a warning sound to fasten the safety hook (step S215). For example, the audio output unit 216 of the mobile terminal 200 repeatedly outputs a warning sound saying "Please fasten the safety belt hook." The worker a hears this warning sound (warning voice) (step S22) and performs the task of hanging the hook 91 of the safety belt 90 at a predetermined position above the car in accordance with the warning voice (step S23).

[0036] When the output of the warning sound in step S215 starts, the image capturing section 217 of the mobile terminal 200 is automatically started, and the display section of the mobile terminal 200 displays the text "Please hook up the safety belt before taking a picture" (step S216). Here, the worker a looks at the mobile terminal 200 to stop the warning sound (step S24). Then, the worker a checks the display made in step S216 and performs an operation to take an image of the hook 91 of the safety belt 90 with the image taking unit 217 of the mobile terminal 200 (step S25).

[0037] When this image is captured, the image analysis unit 218 of the mobile terminal 200 is automatically started, and the image analysis unit 218 confirms by image analysis that the hook 91 of the safety belt 90 is captured in the image captured by the image capture unit 217 (step S217). When it is confirmed by image analysis in the image analysis unit 218 that the hook 91 is captured, the display unit of the mobile terminal 200 displays the words "image capture OK" on the screen (step S218). After checking the message "image capture OK" displayed on the display unit, worker a confirms that there is no problem with the captured image (step S26).

[0038] Then, following the display of the text "image capture OK," the mobile terminal 200 stops the output of the warning sound started in step S215 (step S219). The mobile terminal 200 stops the sound such as "Please fasten the safety belt hook before taking a picture." When stopping the sound, it is also possible to output "Please work safely" just once just before stopping the sound and then stop it. When the worker a confirms that the warning sound has stopped, he or she recognizes that it is safe (step S27) and starts work on the car (step S28).

[0039] After the output of the warning sound is stopped in step S219, the image transmission unit 219 in the mobile terminal 200 is automatically started, and the image transmission unit 219 transmits an image showing the hook 91 to the server 300 (step S220). The image transmitted at this time is stored in a predetermined storage area of ​​the image storage unit 301 of the server 300 (step S301). The image stored in step S301 can be viewed by accessing the server 300 using the image viewing unit 401 of the administrator terminal 400 (step S302). The image transmission in step S220 may be performed by sending an email with the image attached. The destination of the email in this case may be the administrator terminal 400. Furthermore, when transmitting to the server 300 or the administrator terminal 400, not only the image but also the judgment result of the image analysis, whether OK or NG, may be transmitted. Alternatively, only the judgment result of the image analysis, whether OK or NG, may be transmitted to the server 300 or the administrator terminal 400.

[0040] As described above, according to the elevator maintenance work support system of this embodiment, when the worker a turns on the lighting device 101, the mobile terminal 200 carried by the worker a outputs an alarm sound (alarm voice) upon detection of the lighting. This allows the worker a to hang the hook 91 of the safety belt 90 at a predetermined location and perform work while ensuring safety. That is, when the worker a enters a hoistway on top of a car or the like to perform high-altitude work, the worker a must turn on the lighting device (headlight) 101 because the work is done in a dark place. The mobile terminal 200 detects the lighting device 101 being turned on and reliably warns the worker a when working at a high altitude on the elevator, thereby ensuring the safety of the worker a. In addition, since the lighting device 101 is driven by the battery 102, no additional battery is required to provide the illuminance sensor 103 and the communication unit 104. Therefore, the worker a can easily and reliably detect the lighting device 101 being turned on using the mobile terminal 200.

[0041] In addition, the elevator maintenance work support system of this embodiment detects the height from the air pressure obtained by the air pressure sensor 213, and outputs an alarm sound when the worker a is at least one floor above the height at which the worker a entered the building. This makes it possible to reliably warn the worker a only when the worker a enters the elevator shaft to perform work on the car. That is, when the worker a enters the elevator shaft, as described in steps S11 to S27 of FIG. 4 and FIG. 5, the worker a moves to a floor higher than the floor at which the worker a entered the building (the entrance floor: usually the first floor), and at that floor, the car is lowered by a setup operation, the landing door is opened, and the worker a enters the elevator shaft. Therefore, the mobile terminal 200 can appropriately detect the worker a entering the elevator shaft and warn the worker a by determining that the worker a has moved to a floor other than the floor at which the worker a entered the building and issuing a warning.

[0042] Furthermore, in the case of the elevator maintenance work support system of this example, the alarm sound stops when the hook 91 is photographed with the mobile terminal 200, so the worker a checks that the hook 91 is hooked in a predetermined place and then photographs the hook 91. This makes it easier to ensure the safety of the worker a. In addition, the captured images are stored in the server 300 and can be viewed on the administrator terminal 400, so that the administrator in charge of managing the maintenance work on the elevator can also confirm that the work is being carried out while ensuring safety provided by the safety belt 90. In the unlikely event that the manager finds any defect in the hooking state of the hook 91 from the image checked by the manager, the manager can contact the mobile terminal 200 of the worker a by phone or e-mail to provide safety guidance. Furthermore, the images saved in the server 300 can be stored as materials showing that each worker a is working safely.

[0043] [Variations] It should be noted that the embodiment examples described so far have been described in detail in order to explain the present invention in an easily understandable manner, and the present invention is not necessarily limited to those having all of the configurations described. 4 and 5, the lighting of the lighting device 101, the change in height exceeding the threshold value, and the hook detection from the captured image are all performed, but, for example, the warning process may be performed only when the lighting of the lighting device 101 is detected. Alternatively, the warning process may be performed when the lighting of the lighting device 101 is detected and when the height change exceeds the threshold value. Regarding image capture, image analysis may be omitted and the output of a warning may be stopped simply by detecting that an image has been captured.

[0044] In the above embodiment, the height is judged to be one floor higher than the height at which the person entered the building, but the warning may be issued in the same manner when the height at which the person entered is detected to be one floor lower than the height at which the person entered the building. This makes it possible to issue a warning when entering a pit at the bottom of a hoistway, for example, on an underground floor. In addition, in the above-described embodiment, the reference height is the height at the time of entering the building, but for example, the height at which a worker performs a work start operation on a mobile terminal on the first floor (reference floor) may be used as the reference height, and a warning may be issued if there is a change in height of one floor or more (or less) from that height.

[0045] In the above-described embodiment, a warning sound or a warning voice is output as a warning process for the worker, but other warning processing units may be provided, such as a warning process in which the display panel of the mobile terminal 200 flashes in red or vibrates. These flashing and vibration may be used in combination with the output of the warning sound. For example, a warning voice may be issued only once, and thereafter the flashing of the display panel or the vibration of the terminal itself may be continued until an image is captured.

[0046] In the above-described embodiment, the illumination of the lighting device 101 is detected by the illuminance sensor 103. However, the illumination of the lighting device 101 may be detected by another illumination detection sensor, such as a current sensor that detects the current supplied from the battery 102 to the lighting device 101.

[0047] Furthermore, when an illuminance sensor is used, a configuration may be provided with a front illuminance sensor that detects illuminance near the lighting device 101 attached to the front of the helmet 100, and a rear illuminance sensor that detects illuminance at the rear of the helmet. In this case, the communication unit 104 is configured to transmit a detection signal when the difference between the illuminance detected by the front illuminance sensor and the illuminance detected by the rear illuminance sensor is equal to or greater than a threshold value. In other words, the detection signal is obtained by detecting not only the illumination of the lighting device 101, but also the darkness of the surroundings.

[0048] As a result, a detection signal is transmitted only when the lighting device 101 is detected to be on while the vehicle is in a dark place such as a hoistway. Even if the lighting device 101 is turned on before entering the hoistway, an alarm sound is not output until the vehicle enters the hoistway.

[0049] In addition, in the embodiment described above, the image captured by worker a is determined to include the presence of hook 91 and the output of an alarm is stopped. However, the output of the alarm may also be stopped by detecting through image analysis that hook 91 has been hooked in a specified location.

[0050] In addition, a part of the configuration of the elevator maintenance work support system may be placed in another processing device such as a server connected via a network, and data may be exchanged between the multiple processing devices to perform analysis processing similar to that of the elevator maintenance work support system. For example, image analysis may be performed on the server 300 side.

[0051] In addition, in the configuration diagram shown in Figure 2, only the control lines and information lines that are considered necessary for explanation are shown, and not all control lines and information lines in the product are necessarily shown. In reality, it can be considered that almost all components are connected to each other. Furthermore, the process flows shown in the flowcharts of FIGS. 4 and 5 are also examples, and as long as the process results are the same, the order of some of the processes may be changed or multiple processes may be executed simultaneously.

[0052] Furthermore, the mobile terminal 200 is configured to be equipped with an application program for executing an elevator maintenance work support method, which is the processing procedure described in the flowcharts shown in Figures 4 and 5. This program may be prepared in a memory section within the computer that is the mobile terminal 200, or it may be stored on a recording medium such as an external memory, an IC card, an SD card, an optical disk, or the like, and transferred to the mobile terminal 200.
