  In the elevator inspection, qualified personnel having inspection qualifications visit the site, move to the inspection target device, visually check the inspection target device, and then perform pass / fail determination according to the stored determination criteria.

  However, to acquire qualifications, it is necessary to have long-term education and experience, and despite the limited number of qualified personnel, the time required for pass / fail judgment is very small within the time required for inspection. Yes, a qualified person spends most of the time moving to the site and moving between each inspection target device.

  In view of this, a system capable of separating the operation of moving to visually check each inspection target device and the operation of determining pass / fail is constructed. The movement work for visual recognition and the recording of the inspection target device image are performed by an unqualified worker (viewer), and the pass / fail judgment work is collectively performed by the qualified person using the recorded image. Thereby, since the qualified person does not need time to move to the inspection device, it is possible to determine the quality of many elevators in a short time.

  Since the recording of the inspection target device image by the viewer is based on the premise that the viewer does not have the ability to judge the quality of the device, the elevator inspection support system guides the viewer to the recording position and visually checks the inspection target device. The inspection support system records an image when the viewer approaches the inspection target device. Alternatively, when the viewer approaches the inspection target device, the inspection support system instructs the viewer to record an image.

  In the flow S11, the position calculation unit 12 sets the current standing position of the viewer 1 as the position reference point and sets the direction as the direction facing the hatch door 41 in the current position / direction recording unit 12a. Thereafter, whenever the output of the position sensor 3 is generated, the integrator 11 double-integrates the output of the acceleration sensor 4 to calculate the movement distance, and the position calculation unit 12 updates the current position / direction recording unit 12a. I do. The output of the angular velocity sensor 5 is integrated by an integrator 11 to obtain a rotation angle, and the position calculation unit 12 updates the direction of the current position / direction recording unit 12a.

  By integrating, errors are accumulated in the current position and direction of the current position / direction recording unit 12a. In order to prevent the accumulation of errors, when an operation that can clearly grasp the position or direction of the viewer 1 such as pressing the hall button 43 is executed, the work management unit 10 gives an instruction to the control signal unit 13 The car position 30a of the elevator signal 30 is read via the terminal radio device 14, the elevator radio device 32, and the elevator control panel 31, and the current position and direction recorded in the current position / direction recording unit 12a are corrected.

  In addition, each work site has a two-dimensional or three-dimensional position database that records the positional relationship of each device / device, so that the positional relationship between the database and the current position is compared, and the current viewer 1 You can grasp the standing position. The database may be configured to be included in the work DB 16, or may be configured to include a recording unit for each site, and to capture the location database of the site when the viewer arrives at the site. The position database may include information on the orientation of each device / apparatus and may be used to determine whether the inspection target device and the camera 7 face each other. A marker is attached to the inspection target device or the vicinity thereof, and the camera 7 uses the marker. You may determine opposition with an inspection object apparatus by having recognized. For example, in the case of a circle marker, if the circle is recognized as an ellipse, it may be determined that they are not facing each other. If the circle is a predetermined size or less, the orientation of the camera 7 itself However, it may be determined that they are not facing each other because the distance is too far. In addition, even if the inspection target device and the camera 7 are close to each other by including wall and floor information in the position database, it may be determined that there is actually a wall or a ceiling and the two are not facing each other.

  In flow S <b> 12, the elevator control panel 31 is controlled via the control signal unit 13, the terminal wireless device 14, and the elevator wireless device 32. The elevator control panel 31 operates the display instruction 30d during inspection of the elevator signal 30 to display the inspection door 42 on the hatch door 41.

  In flow S13, the work management unit 10 refers to the work reference sheet 16a in the work DB 16 and newly creates an inspection record sheet 17a and an operation record sheet 18a.

  FIG. 4 is an example of an inspection record sheet 17a of the elevator inspection support system according to the present invention. In the inspection record sheet 17a, the work item 50, the inspection floor 51 of the work item 50, the inspection position 52 in each operation item 50 and each inspection floor 51, and the work content 58 in each inspection position 52 are arranged in a table. The work status 53, the inspection image name 54, and the determination result 55 can be input.

  FIG. 5 is an example of the status recording sheet 18a of the elevator inspection support system according to the present invention. In the status recording sheet 18a, the work execution contents 56 and the state image names 57 corresponding to the execution contents 56 can be registered. In the status recording sheet 18a, as the execution contents 56, a start time (before start) field (denoted as “start”) and an end time (after end) field (denoted as “end”) for one work And the state image name 57 at the start and the state image name 57 at the end are registered.

  When the start process S1 is completed, the work management unit 10 performs the following process as the confirmation process S2 of the hatch door 41.

  In flow S <b> 21, the work management unit 10 selects an instruction voice from the voice data 15 a of the voice output unit 15, and gives a voice instruction to the viewer 1 through the speaker 6 so as to visually recognize the opening / closing of the hatch door 41 from the elevator hall 40 side. Issue. Thus, in the elevator inspection support system of the present embodiment, the viewer 1 is guided to the inspection target device (inspection position) to be inspected.

  In flow S <b> 22, the work management unit 10 confirms that the viewer 1 has moved in the designated position and direction with the current position / direction recording unit 12 a, and then sends an opening / closing instruction for the hatch door 41 via the control signal unit 13. Issued to the elevator control panel 31. In response to this instruction, the elevator control panel 31 opens and closes the hatch door 41 according to the door opening / closing instruction 30e of the elevator signal 30.

  In the flow S23, the work management unit 10 monitors the opening / closing operation of the hatch door 41 by the control signal unit 13, and when the operation of the door switch signal 30c is detected, the inspection image captured by the camera 7 connected to the image input unit 19 and The operation sound collected by the microphone 8 connected to the voice input unit 21 is stored in the image recording unit 17 b in the inspection recording unit 17. In this case, the camera 7 moves to the position instructed by the voice instruction and the camera 7 is detected by the position sensor 3 to detect that the camera 7 has faced the inspection target device. Take an inspection image of the inspection target device.

  Depending on the shooting environment, there may be a case where it is difficult for the qualified person 35 to check because the shot inspection image is blurred or overexposed or the image is too dark. Accordingly, a light (not shown) may be provided in the camera 7 or the viewer 1 so that the illuminance during shooting is kept constant. In addition, a configuration in which a plurality of images are stored by shooting at the time of shooting is effective in preventing the trouble of re-taking later. In addition, when it is detected that blur or the like has occurred in the captured image, the microphone 8 may be instructed to point the camera 7 at the inspection target device again. Regarding such a photographing method, it is desirable to apply not only to the inspection image, but also to the state image. In addition, what is necessary is just to use the existing image processing technique about determination of generation | occurrence | production of a blur etc.

  When storage of the inspection image is completed, “completed” is registered in the column of the work status 53 and the inspection image name stored in the image recording unit 17b is registered in the column of the inspection image name 54 in the inspection recording sheet 17a.

  In flow S24, the work management unit 10 issues a voice instruction from the speaker 6 to the viewer 1 so as to press the hall button 43 (see FIG. 2). The viewer 1 pushes the hole button 43 while visually recognizing the hole button 43 according to the voice instruction.

  In the flow S25, the work management unit 10 monitors the push button signal 30b by the control signal unit 13, and the camera 7 connected to the image input 19 displays an image in which the push button signal 30b is operating when the hall button 43 is pushed. Take a picture. The captured image is stored in the image recording unit 17b in the inspection recording unit 17 as an inspection image. When storage of the inspection image is completed, “completed” is registered in the column of the work status 53 and the inspection image name stored in the image recording unit 17b is registered in the column of the inspection image name 54 in the inspection recording sheet 17a.

  In the flow S26, the work management unit 10 confirms the inspection record sheet 17a, and determines whether there is an uninspected floor where the work situation 53 is not described. That is, it is determined whether or not there is a floor in which “Done” is not registered in the work status 53 column.

  If there is a floor that has not been inspected, instruct the voice to move to the floor that has not been inspected in flow S27, and wait for the current position and direction of the current position / direction recording unit 12a to become the specified position and direction. The inspection work is repeated from the flow S21.

  When “Done” is written in all the columns of the work status 53, the tower confirmation process S3 which is the next work item is started. In the tower confirmation process S3, the following process is performed.

  In flow S31, a boarding instruction is given to the viewer 1 on the car. The viewer 1 moves the elevator car (not shown) to a position suitable for boarding and stops it, and then moves to a position where boarding is possible. The movement of the car and the movement of the viewer 1 at this time are instructed by the controller 2 by voice.

  Next, the hatch door 41 is manually opened to get on the car.

  In the flow S32, the work management unit 10 grasps from the current position and direction of the current position / direction recording unit 12a that the viewer 1 is in the position and direction overlooking the car. Next, when the work management unit 10 confirms that the hatch door 41 is opened by the operation of the door switch signal 30 c, the camera 7 captures an image (state image) on the car at that time. The work management unit 10 stores the captured state image in the image recording unit 18 b in the state recording unit 18, and also stores the state image name in the column of execution content and the state image name 57 in the column of execution content 56 of the state recording sheet 18 a. Register. In addition, although the present Example demonstrates the operation | work of the place where the hatch door 41 exists, when performing an operation | work in the place which does not depend on the elevator signal 30, the structure which image | photographs the image before and behind a work | operation manually by the viewer 1. It is also good. Alternatively, it is possible to detect that the camera 7 and the inspection target device are opposite to each other and that the distance between the viewer 1 and the inspection target device is equal to or less than a predetermined value and automatically take a state image. Then, the microphone 8 may be announced to shoot a state image.

  In flow S33, the work management unit 10 issues a voice instruction to the viewer 1 from the speaker 6 so that the hatch door 41 is slightly opened and closed manually. The viewer 1 opens and closes the hatch door 41 in response to this voice instruction.

  In flow S <b> 34, the work management unit 10 monitors the door switch signal 30 c by the control signal unit 13, takes an image (inspection image) when the door switch is operated, and the inspection recording unit 17 And stored in the image recording unit 17b. When the storage of the inspection image is completed, the work management unit 10 registers “Done” in the column of the work situation 53 in the inspection record sheet 17a, and registers the inspection image name of the stored inspection image in the column of the inspection image name 54. To do.

  In the flow S35, the work management unit 10 confirms the inspection record sheet 17a, and determines whether there is an uninspected floor where the work situation 53 is not described. That is, it is determined whether or not there is a floor in which “Done” is not registered in the work status 53 column.

  If there is an uninspected floor, a voice instruction is given to move to the uninspected floor in flow S36, and the current position / direction of the current position / direction recording unit 12a is waited until the specified position and direction are reached. When the position and direction are reached, the inspection work is repeated from the flow S33.

  When “Done” is described in all the columns of the work situation 53, the work management unit 10 gives a voice instruction to the viewer 1 to get out of the car from the flow 37.

  In the flow 38, the work management unit 10 grasps the current position and direction of the current position / direction recording unit 12a from the current position / direction recording unit 12a that the viewer 1 is looking over the car. When the work management unit 10 confirms that the hatch door 41 is closed by the operation of the door switch signal 30c by the control signal unit 13, the state recording unit 18 displays an image (state image) immediately before the hatch door 41 is closed, which is captured by the camera 7. And the status image name is registered in the execution content 56 column and the status image name 57 column of the status recording sheet 18a.

  When the tower confirmation process S3 is completed, the restoration confirmation process S4 is performed.

  In the flow S41, the work management unit 10 confirms the record on the state recording sheet 18a, and if there are a plurality of cars getting on and off, the state corresponding to the oldest record of the car getting on and off ("car getting on and off starting"). The state image name of the image and the state image name of the state image corresponding to the latest record of getting off the car are extracted from the state image name 57 column. The work management unit 10 takes out the oldest state image and the latest state image from the image recording unit 18b based on the extracted oldest state image name and the latest state image name, and compares the two images with the state. This is performed by the determination unit 23. If there is a difference between the two images, there is a possibility that the device installed on the car has not been correctly restored, so the state determination unit 23 sends a sound for alerting the sound output 15 from the speaker 6. To instruct. Upon receiving this instruction, the viewer 1 can reconfirm the state on the car and correctly restore the equipment on the car.

  As a specific example of the equipment on the car, for example, a safety fence can be cited. The safety fence is not shown in the state image on the car at the start of getting on and off the car. After the image at the start of getting on and off the car is taken, the viewer 1 installs a safety fence on the car in order to ensure the safety of the work. After the work is completed, store the safety fence on the car and restore the car. After restoring the car, a state image on the car is taken at the end of getting on and off the car. If the safety fence is not stored at the end of getting on and off the car, the state image on the car at the start of getting on and off the car does not match the state image on the car at the end of getting on and off the car, resulting in a difference. In this case, the state determination unit 23 instructs the audio output 15 to play a sound for alerting from the speaker 6.

  When comparing images, for example, color information of two images before and after work, a local feature amount such as SIFT feature amount (Scale-Invariant Feature Transform) is extracted, and the color information and the local feature amount are compared, What is necessary is just to determine similarity by comparing with a predetermined threshold value. Also, instead of comparing the two images before and after the work, a database of a plurality of images taken in the field after the work that should or should not be photographed in advance is maintained. You may determine the similarity of an image and the image in the said database, and may determine whether alerting is performed. For example, in the above-described state image on the car, since the safety fence must be stored at the time of getting on and off the car, a plurality of images showing the safety fence are held in advance as a database, and each of the images in the database is stored. A comparison may be made between the image and the state image after the completion of the work, and if it is determined that the image is similar to the image showing the safety fence, a configuration for alerting may be used. Or you may hold | maintain the image which does not show a safety fence beforehand in a database, and compare with those images, and if it is judged that it is similar, you may determine that alerting is unnecessary. Furthermore, the accuracy of restoration confirmation can be further increased by performing the determination of the similarity between two images before and after the work and the determination of the similarity with an image database held in advance.

  In the flow S42, it is determined whether there is a difference between the images before and after the work based on the comparison result of the images in the flow S41. At that time, a plurality of threshold values for determining the similarity may be provided, and the content instructed in the next flow S43 may be changed based on the similarity.

  In addition, the comparison before and after the work by the image is not only on boarding / exiting the car, but also when entering / exiting the pit, opening / closing the elevator control panel 31, etc., by additionally describing in the flowchart 10a, The recovery status of the part is automatically confirmed.

  For example, in the control panel 31, a state image of the control panel 31 is taken before the start of the inspection work, and a state image of the control board 31 is taken after the end of the inspection work. Both the state image of the control panel 31 before the start of the inspection work and the state image of the control panel 31 after the end of the inspection work must be the same with the lid closed. When the cover is opened in the state image of the control panel 31 after the inspection work is completed, the state image does not coincide with the state image before the start of the inspection work, and a difference occurs. In this case, the state determination unit 23 instructs the audio output 15 to play a sound for alerting from the speaker 6.

  The inspection image registered in the image recording unit 17b of the inspection recording unit 17 is stored together with the inspection recording sheet 17a by the terminal transmission processing unit 22 in the reception determination recording unit 37 via the network 34 and the center transmission device 38. The The inspection images stored in the reception determination recording unit 37 are sequentially displayed on the display 36 by the qualified person 35, and the quality is determined based on the recorded inspection images, and the quality is described in the determination column 55 of the inspection recording sheet 17a.

  The inspection image and the state image may be a still image or a moving image.

  As described above, in the embodiment according to the present invention, the controller 2 of the elevator inspection support apparatus automatically creates an inspection image by the operation of the viewer 1, and the qualified person records the quality determination of the equipment. By collectively referring to the images, it is possible to eliminate the work of moving qualified persons and greatly reduce the time required for inspection.

  In addition, by comparing the images at the start and end of the inspection work of each device, it is possible to prevent new troubles and failures caused by a recovery omission at the time of inspection.

  In the maintenance support system disclosed in Japanese Patent Application Laid-Open No. 2005-216137, in order to recognize jigs, tools, parts, materials, etc., it is necessary to affix a barcode to the jigs, tools, parts, materials, etc. A lot of prior work is required for pasting barcodes. According to the present embodiment, it is possible to specify the inspection target device and perform the inspection work without performing the operation of attaching the barcode to the inspection target device or the work tool.

  Each processing unit, each recording unit, and the like provided in the controller 2 of the present embodiment are not limited to the configuration in FIG. 1 and can have various configurations. Accordingly, the function of each processing unit and each recording unit may be considered as the function of the controller 2.

  In addition, this invention is not limited to an above-described Example, Various modifications are included. For example, the above-described embodiments have been described in detail for easy understanding of the present invention, and are not necessarily limited to those having all the configurations. In addition, it is possible to add, delete, and replace other configurations for a part of the configuration of the embodiment.
