The terminal device 1 can be connected to the video camera 10 and the elevator control unit 8 of the elevator by wireless communication, and can receive data from the video camera 10 and the elevator control unit 8.

  The terminal device 1 is carried by an inspection worker 5 who performs maintenance and inspection work for the elevator, and includes an image collection unit 11, an elevator state collection unit 9, an inspection result data input unit 6, and a work instruction unit 4. The terminal device 1 also includes an output unit 4a that displays work instructions and data. The output unit 4a may output sound and vibration in addition to characters. The image collection unit 11 acquires the video captured by the video camera 10 and transmits it to the inspection work support device 2 as image data. The elevator state collection unit 9 acquires information on the state of the elevator (for example, the position of the car, the operation mode, and the state of each switch of the elevator) from the elevator control unit 8 and transmits the information to the inspection work support device 2. The inspection result data input unit 6 receives the result of inspection by the inspection operator 5. The work instruction unit 4 outputs a work instruction, data to be displayed, and attention information and warning information described later to the output unit 4a.

  The inspection work support device 2 is provided in an elevator management center, and is configured by a server or the like. The image information storage unit 12, the image analysis unit 13, the abnormality detection unit 14, the work instruction determination unit 15, and the content storage unit 7 are included. Is provided. The image information storage unit 12 stores in advance image information used for analyzing the image data transmitted from the terminal device 1. The image analysis unit 13 analyzes the image data transmitted from the terminal device 1 (image data acquired by the image collection unit 11 from the video captured by the video camera 10). When analyzing image data, the image analysis unit 13 can also use image information stored in the image information storage unit 12. The abnormality detection unit 14 uses the information obtained from the elevator control unit 8 and the video camera 10 to determine whether there is an abnormal state in the maintenance / inspection work performed by the inspection worker 5, and abnormalities in the work (for example, , Danger and work leakage). The work instruction determination unit 15 selects the next work procedure from the content storage unit 7 and notifies the inspection worker 5 via the terminal device 1. In addition, the work instruction determination unit 15 causes the output unit 4 a to output caution information and warning information described later via the work instruction unit 4.

For example, the inspection worker 5 preferably wears the video camera 10 on his / her head or chest.

  The elevator control unit 8 is, for example, a control panel, controls the operation of the elevator, and grasps the state of the elevator. The elevator control unit 8 performs, for example, raising and lowering of the car, opening and closing of the car door and the landing door, and the position of the car, the operation mode, and the state of each switch of the elevator (turned on or off) Information, etc.).

  FIG. 2 is a diagram showing a schematic configuration of the elevator inspection work support system according to the present embodiment, similarly to FIG. 1. The inspection work support system 21 shown in FIG. 2 has the same configuration as the inspection work support system 20 shown in FIG. 1, except that the output unit 4 a is separated from the terminal device 1. And different. As shown in FIG. 2, the output unit 4 a can be installed separately from the terminal device 1. For example, when the output unit 4a is provided in a glasses-type wearable terminal, the output unit 4a can be installed at the tip of the line of sight of the inspection worker 5 wearing the wearable terminal. There is an advantage that it is easy to confirm a work instruction to be displayed.

  Generally, elevator maintenance and inspection work is performed as follows. The inspection worker 5 confirms the work procedure sent from the work instruction determination unit 15 of the inspection work support device 2 to the work instruction unit 4 of the terminal device 1 and performs maintenance and inspection work of the elevator. When the inspection operator 5 inputs the inspection result to the inspection result data input unit 6 of the terminal device 1, the terminal device 1 transmits the inspection result data to the work instruction determination unit 15 of the inspection work support device 2. Upon receiving the inspection result data, the work instruction determination unit 15 selects the next work procedure from the content storage unit 7 and transmits it to the work instruction unit 4 of the terminal device 1. By repeating these procedures, elevator maintenance and inspection work is performed.

  However, the inspection worker 5 does not always behave correctly according to the work procedure sent from the work instruction determination unit 15. For example, when carrying out the work performed on a car in a five-story building, when the inspection worker 5 stops the car on the fourth floor and tries to get on the car from the fifth floor, Suppose the customer calls you to the first floor. The inspection worker 5 goes to the first floor with the car stopped on the fourth floor, and after having finished working with the customer, tries to get on the car to resume the work. At this time, if the inspection worker 5 misunderstands that the car has been stopped on the first floor, the inspection worker 5 tries to get on the car from the second floor. Then, since the car is actually located on the fourth floor, the inspection worker 5 may fall from the second floor landing to the bottom of the elevator hoistway.

  The elevator inspection work support system according to the present embodiment can notify the inspection worker 5 of such danger in the maintenance and inspection work of the elevator, and enables the inspection worker 5 to safely perform the maintenance inspection work. be able to.

  Hereinafter, a series of procedures for elevator maintenance and inspection work using the elevator inspection work support system according to the present embodiment will be described with reference to FIGS. 3 and 4. Hereinafter, a case where the inspection worker 5 gets on the car and performs the maintenance inspection work will be described as an example. The elevator inspection work support system according to the present embodiment can also be used for other maintenance inspection work, for example, a hoisting machine inspection work or an inspection work at the bottom (pit) of a hoistway.

  FIG. 3 shows a procedure when the inspection worker 5 gets into the car from the landing and performs the inspection work on the car in the maintenance work using the elevator work work support system according to the present embodiment. It is a flowchart.

  In S <b> 1, the work instruction determination unit 15 of the inspection work support device 2 selects a work procedure from the content storage unit 7 based on the work schedule, and transmits the work procedure to the work instruction unit 4 of the terminal device 1. The work instruction unit 4 displays the transmitted work procedure (work instruction) on the output unit 4a. The inspection worker 5 performs work according to the work instructions displayed on the output unit 4a. In this embodiment, the inspection work on the car is a work instruction, and the inspection worker 5 tries to get on the car.

  In S2, the elevator state collection unit 9 of the terminal device 1 acquires information on the state of the elevator from the elevator control unit 8, and determines whether the operation mode of the elevator is in the low speed mode. The inspection worker 5 can safely get on the car in the low speed mode, but it is dangerous to get on the car in the low speed mode. If the elevator operation mode is not the low speed mode, the process proceeds to S3. If the elevator operation mode is the low speed mode, the process proceeds to S6.

  In S3, the work instructing unit 4 detects an abnormality (danger) in the maintenance / inspection work performed by the inspection worker 5, and outputs caution information for notifying the inspection worker 5 of this abnormality to the output unit 4a. To do. This caution information is a notification that informs the inspection worker 5 that it is dangerous for the inspection operator 5 to get on the car. The output unit 4a may output a character display as attention information, or may output sound or vibration.

  In S4, the elevator state collection unit 9 acquires information on the state of the elevator from the elevator control unit 8, and determines whether the landing door switch is turned off at an arbitrary floor. The fact that the landing door switch is turned off indicates that the inspection operator 5 is about to open the landing door. If the landing door switch is turned off, the process proceeds to S5, and if not turned off, the process returns to S2.

  In S5, the work instructing unit 4 outputs warning information for notifying the inspection operator 5 of the abnormality (danger) in the maintenance / inspection work performed by the inspection operator 5 to the output unit 4a. To do. This warning information is a notification that informs the inspection operator 5 that it is very dangerous for the inspection operator 5 to open the landing door in order to get on the car. The output unit 4a may output a character display as warning information, or may output a sound or vibration. However, the warning information is output so that one or more of the character color, the blinking of the character, the loudness of the sound, the vibration level, etc. is different from the caution information, and the danger is stronger than the caution information. To do.

  S6 is a process performed when it is determined in S2 that the elevator operation mode is the low speed mode. In S6, the elevator state collection unit 9 acquires information on the state of the elevator from the elevator control unit 8, and acquires the stop floor of the car.

  In S <b> 7, the image analysis unit 13 of the inspection work support device 2 acquires the position (floor) where the inspection worker 5 is located from the video imaged by the video camera 10 by the method described below. The video camera 10 photographs a floor display installed in an elevator hall or a staircase of a building. The image analysis unit 13 receives the image data of the video captured by the video camera 10 from the image collection unit 11 of the terminal device 1, and extracts and extracts numbers from the image data using an existing image processing technique. It is determined that the number represents the floor where the inspection worker 5 is located.

  The output unit 4a of the terminal device 1 displays a number that the image analysis unit 13 determines to represent the floor where the inspection worker 5 is located. The inspection operator 5 can confirm whether the image analysis unit 13 has correctly determined the floor where the inspection operator 5 is located by looking at the numbers displayed by the output unit 4a. When the image analysis unit 13 does not correctly determine the floor where the inspection worker 5 is located, the inspection worker 5 takes a floor display with the video camera 10 and the image analysis unit 13 has the inspection worker 5. The floor can be judged correctly. When the image analysis unit 13 cannot extract numbers from the image data, the work instruction determining unit 15 sends the floor to the output unit 4a via the work instruction unit 4 and the inspection worker 5 using the video camera 10. An instruction that prompts the user to shoot the display is displayed so that the image analysis unit 13 can extract numbers from the image data.

  In S8, the abnormality detection unit 14 of the inspection work support device 2 determines whether or not the inspection worker 5 is in a safe position. In the present embodiment, the abnormality detection unit 14 compares the stop floor of the car acquired by the elevator state collection unit 9 in S6 with the floor where the inspection worker 5 acquired by the image analysis unit 13 in S7. To make a decision. As a result of the comparison, if it is determined that the inspection worker 5 is at a safe floor (position), the process proceeds to S9. If it is determined that the inspection worker 5 is at an unsafe floor (position), the process proceeds to S3. The case where the inspection worker 5 is on the safe floor is the case where the inspection worker 5 is on the stop floor of the car or on the floor one floor above the stop floor of the car.

  When the inspection worker 5 is on an unsafe floor, that is, when the inspection worker 5 is not on either the stop floor of the car or the floor one floor above the stop floor of the car, When the inspection worker 5 tries to get on the car and opens the landing door, there is a risk of falling to the elevator hoistway. For this reason, the inspection operator 5 is informed that there is a danger in the work to be performed by executing the processes of S3 to S5 and outputting the caution information and warning information. The work instruction determination unit 15 causes the output unit 4 a to output these attention information and warning information via the work instruction unit 4.

  S9 is a process performed when it is determined in S8 that the inspection worker 5 is on a safe floor (position). The inspection worker 5 manually opens the landing door and gets on the car, and performs the inspection work on the car. At this time, the inspection worker 5 turns on a switch installed in the control box on the car in order to perform the inspection work. In this embodiment, the inspection worker 5 turns on the door stop switch, the operation switch, and the stop switch. The inspection result data input unit 6 of the terminal device 1 stands by until an inspection result is input from the inspection operator 5. During the inspection work on the passenger car, since the inspection operator 5 closes the landing door, the landing door switch is turned on.

  FIG. 4 is a flowchart showing a procedure when the inspection worker 5 enters the landing from the passenger car in the maintenance inspection work using the elevator inspection work support system according to the present embodiment.

  In S <b> 10, the work instruction determination unit 15 of the inspection work support device 2 selects the next work procedure from the content storage unit 7 based on the work schedule, and transmits it to the work instruction unit 4 of the terminal device 1. The work instruction unit 4 displays the transmitted work procedure (work instruction) on the output unit 4a. The inspection worker 5 performs work according to the work instructions displayed on the output unit 4a. In this embodiment, the inspection work (for example, inspection of the display device) performed at the landing is the next work instruction, and the inspection worker 5 tries to go out from the platform to the landing to perform the next inspection work.

  In S <b> 11, the elevator state collection unit 9 of the terminal device 1 acquires information on the state of the elevator from the elevator control unit 8, and determines whether the landing door switch is turned off at an arbitrary floor. The fact that the landing door switch is turned off indicates that the inspection worker 5 is going to open the landing door in order to enter the landing. If the landing door switch is turned off, the process proceeds to S12. The inspection worker 5 opens the landing door and enters the landing from the platform before starting the processing of S12. However, the inspection worker 5 is supposed to enter the landing after turning off the switches (for example, door stop switch, operation switch, and stop switch) installed on the passenger car.

  In S12, the abnormality detection unit 14 of the inspection work support device 2 uses the information on the state of the elevator from the elevator control unit 8 to check whether the door stop switch installed on the passenger car is off (door stop). Whether the switch has returned to the normal state). The door stop switch is a switch that prevents the landing door from opening when it is turned on. If the door stop switch is off, the process proceeds to S17, and if the door stop switch is not off, the process proceeds to S13.

  In S17, the abnormality detection unit 14 of the inspection work support device 2 uses the information on the state of the elevator from the elevator control unit 8 to check whether the operation switch installed on the car is off (the operation switch is Whether the normal state has been restored). The operation switch is a switch that allows the car to be driven only on the car when turned on. If the operation switch is off, the process proceeds to S18, and if the operation switch is not off, the process proceeds to S13.

  In S18, the abnormality detection unit 14 of the inspection work support device 2 uses the information on the state of the elevator from the elevator control unit 8 to check whether the stop switch installed on the passenger car is off (the stop switch is Whether the normal state has been restored). The stop switch is a switch that prevents the car from moving when it is turned on. If the stop switch is off, the process proceeds to S19, and if the stop switch is not off, the process proceeds to S13.

  S13 is a process executed when the door stop switch is not turned off at S12, when the operation switch is not turned off at S17, and when the stop switch is not turned off at S18.

  In S <b> 13, the image analysis unit 13 of the inspection work support device 2 acquires the position where the inspection worker 5 is located from the video imaged by the video camera 10 by the method described below. In this embodiment, since the inspection worker 5 at the landing manually closes the landing door, the image analysis unit 13 determines that the inspection worker 5 is at the landing when the landing door starts to close. The video camera 10 takes a picture of the inspection worker 5 at the landing manually closing the landing door and starting to close the landing door. The image analysis unit 13 transmits image data of a video taken by the video camera 10 from the image collection unit 11 of the terminal device 1, and uses the existing image processing technique from the image data to open a landing opening (a landing door). When the size of the opening is reduced with time, it is determined that the landing door has started to close. If it is determined that the landing door has started to close, the process proceeds to S14. If it is not determined that the landing door has started to close, the process returns to S12.

  In the inspection work, since the inspection operator 5 manually opens and closes the landing door (that is, the landing door is not moved by a motor), the elevator controller 8 cannot recognize whether the landing door has started to close. . For this reason, in the present embodiment, it is determined whether or not the landing door has started to be closed using the video taken by the video camera 10. There is also an advantage that the position where the inspection worker 5 is present can be acquired by making a determination using the video of the video camera 10.

  In S14, the abnormality detection unit 14 of the inspection work support device 2 detects that there is a work leak. In this embodiment, the abnormality detection unit 14 determines that the switch on the car is not turned off in S12, S17, or S18, and determines that the inspection worker 5 is on the landing in S13. Therefore, the work leakage that there is a switch on the car that the inspection worker 5 did not turn off is detected. When the abnormality detection unit 14 detects a work leakage, the work instruction unit 4 outputs caution information to the output unit 4a. This caution information may be that the switch on the car is not turned off (that is, there is a switch on the car that the inspection operator 5 did not turn off, which may cause a work abnormality such as work leakage). ) To notify the inspection operator 5. The output unit 4a may output a character display as attention information, or may output sound or vibration. The work instruction determination unit 15 causes the output unit 4 a to output the caution information via the work instruction unit 4.

  In S15, the elevator state collection unit 9 acquires information on the state of the elevator from the elevator control unit 8, and determines whether the landing door switch that was turned off in S11 is turned on. The fact that the landing door switch is turned on indicates that the inspection worker 5 at the landing has completely closed the landing door. If the landing door switch is turned on, the process proceeds to S16; otherwise, the process returns to S12.

  In S16, the abnormality detection unit 14 detects that there is a work leak. In this embodiment, the abnormality detection unit 14 determines that the switch on the car is not turned off in S12, S17, or S18, and determines that the inspection worker 5 is on the landing in S13. Since it is determined in S15 that the inspection worker 5 has completely closed the landing door, the inspection operator 5 is about to finish the work even though there is a switch on the car that is not turned off. A work leak is detected that there is a switch on the car that the inspection worker 5 forgets to turn off. When the abnormality detection unit 14 detects a work leakage, the work instruction unit 4 outputs warning information to the output unit 4a. This warning information indicates that the landing door is completely closed even though some switches on the car are not turned off (that is, the switch on the car that the inspection operator 5 did not turn off). This is a notification informing the inspection worker 5 that there is a work abnormality such as work leakage. The output unit 4a may output a character display as warning information, or may output a sound or vibration. However, the warning information differs from the caution information in one or more of the character color, the blinking of the character, the loudness of the sound, and the magnitude of the vibration, so that the work omission is notified more strongly than the caution information. Output. The work instruction determination unit 15 causes the output unit 4 a to output the warning information via the work instruction unit 4.

  S19 is a process executed when the door stop switch is turned off in S12, the operation switch is turned off in S17, and the stop switch is turned off in S18. In this case, all the switches on the car are turned off and returned to the normal state. The inspection worker 5 performs the next inspection work in accordance with the work instruction displayed on the output unit 4a in S10. The inspection result data input unit 6 of the terminal device 1 stands by until an inspection result is input from the inspection operator 5.

  In the above embodiment, the case where the inspection worker 5 gets on the car and performs the maintenance inspection work has been described as an example. The elevator inspection work support system according to the present embodiment can also be used for the inspection work of the elevator hoisting machine and the inspection work at the bottom (pit) of the hoistway.

  When the elevator inspection work support system according to the present embodiment is used for the hoisting machine inspection work, the video camera 10 held by the inspecting operator 5 captures the video of the hoisting machine, and the image analysis unit 13 The image of the hoisting machine is extracted from the image data of the video taken by the video camera 10 using the image of the hoisting machine stored in advance as image information in the information storage unit 12 and the existing image processing technology. By doing so, the position where the inspection worker 5 is present is acquired (it is understood that the inspection worker 5 is in the vicinity of the hoist).

  For example, when the inspection operator 5 performs an operation of moving the hoisting machine, the abnormality detecting unit 14 operates the hoisting machine from the information on the elevator state acquired by the elevator state collecting unit 9 from the elevator control unit 8. Know what you did. Then, when the size of the hoisting machine in the image extracted by the image analysis unit 13 is equal to or smaller than a predetermined size, the abnormality detecting unit 14 detects the hoisting machine in which the inspection operator 5 is operating. It is determined that the user is in a remote position, that is, in a safe position.

  When the elevator inspection work support system according to the present embodiment is used for the inspection work in the pit, the video camera 10 held by the inspection worker 5 captures the video in the pit, and the image analysis unit 13 stores the image information. Image data of an image captured by the video camera 10 using an image of an object (for example, a shock absorber) existing in a pit previously stored as image information in the unit 12 and an existing image processing technique. By extracting an image of an object existing in the pit, a position where the inspection worker 5 is present is acquired (it is understood that the inspection worker 5 is in the pit).

  For example, when the inspection worker 5 performs the operation of raising and lowering the car, the abnormality detection unit 14 raises and lowers the car from the information on the state of the elevator acquired by the elevator state collection unit 9 from the elevator control unit 8. Grasp that. Then, the abnormality detection unit 14 estimates the position in the pit of the inspection worker 5 from the image of the object existing in the pit extracted by the image analysis unit 13, and the inspection worker 5 connects to the car or the car. If it is not under the weight, the inspection worker 5 is determined to be in a safe position. The anomaly detection unit 14 is preliminarily input with data on the arrangement of the objects present in the pits and data on the position of the car and the weight, and these data and the image in the image extracted by the image analysis unit 13 are input. The position of the inspection worker 5 is estimated using the size of the object, and it is determined whether or not the inspection worker 5 is in a safe position.
