As shown in FIG. 1, the elevator apparatus 2 </ b> A includes a car 10, a counterweight 20, a main rope 30, a hoisting machine 40, and an elevator control unit 50. The car 10, the counterweight 20 and the main rope 30 are installed in a hoistway 60.

  The passenger car 10 is used by a user. The car 10 is installed between a pair of car guide rails (not shown) installed in the hoistway 60, and moves up and down along the car guide rails to move up and down the hoistway 60. The car 10 is provided with a car-side door (not shown) that can be opened and closed. The car-side door closes and opens the car-side entrance / exit of the car 10. The car-side door is kept closed when the car is raised and lowered, and when the car is landed, the car-side door is changed from the closed state to the open state by a driving device (not shown).

  The counterweight 20 moves up and down in the hoistway 60 in conjunction with the raising and lowering of the car 10. The counterweight 20 is installed between a pair of weight guide rails (not shown), and moves up and down along the weight guide rails via a guide device (not shown) installed at least one of the weight guide rails. Here, the weight of the counterweight 20 is set so as to balance the car with the hoisting machine 40 sandwiched when the car has a predetermined load (for example, about 0 to 1/2 with respect to the maximum load). ing.

  The main rope 30 is one or more ropes that connect the car 10 and the counterweight 20, and is wound around a main sheave (not shown) of the hoisting machine 40. The main rope 30 raises and lowers the car 10 and the counterweight 20 in a traction manner. The main rope 30 has one end connected to the car 10 and the other end connected to the counterweight 20. One end of the main rope 30 is fixed to the upper part in the vertical direction of the car 10, and the other end is fixed to the upper part in the vertical direction of the counterweight 20.

  The hoisting machine 40 is rotated by a motor (not shown) to wind up the main rope 30 wound around the main sheave, and the relative position of the car 10 and the counterweight 20 in the ascending / descending direction is changed. 10 is moved up and down in the hoistway 60. The hoisting machine 40 is connected to the elevator control unit 50, and drive control of the motor is performed by electric power supplied via the elevator control unit 50.

  The elevator control unit 50 controls the elevator device 2A, and controls driving of the motor of the hoisting machine 40, or receives a call registration signal from a landing operation panel (not shown) to register the car 10 as a call. To do.

  The elevator maintenance work support device 1A further includes an operator detection unit 70, an approaching object position detection unit 80, an operation detection unit 90, a determination unit 100, an approach determination time storage unit 110, a line-of-sight detection unit 120, A line-of-sight determination time storage unit 130, a notification unit 140, and a control unit 150 are provided.

  The worker detection unit 70 detects the position of the worker P1 in the hoistway 60. For example, the worker detection unit 70 is working whether the worker P1 is working in a pit (not shown) of the hoistway 60, is working on the car 10, or other place. Detect whether or not For example, when working in a pit, the worker P1 operates various switches of a pit safety switch box (not shown) installed in the pit. The worker detection unit 70 receives a detection signal indicating that the worker P1 is working in the pit when an operation signal output by the operator P1 operating various switches of the pit safety switch box is input. Output to the determination unit 100. For example, when the pit inspection switch of the pit safety switch box is turned “ON” and the inspection operation mode is set, the worker detection unit 70 determines a detection signal indicating that the worker P1 is working in the pit. Output to the unit 100. When the pit inspection switch is turned “OFF” and the inspection operation mode is released, the worker detection unit 70 outputs a detection signal indicating that the worker P1 is not working in the pit to the determination unit 100. . In addition to the pit inspection switch, the pit safety switch box includes a pit safety switch and a pit securing lighting switch, and these switches are combined to determine whether the worker P1 is working in the pit. May be.

  When the worker P1 works on the car 10, the worker P1 operates various switches of a car switch box (not shown) installed on the car 10. The worker detection unit 70 confirms that the worker P1 is working on the car 10 when an operation signal output by operating various switches of the car top switch box is input by the worker P1. The detection signal shown is output to the determination unit 100. For example, when the inspection switch on the car on the car switch box is turned “ON” and the inspection operation mode is set, the worker detection unit 70 confirms that the worker P1 is working on the car 10. The detection signal shown is output to the determination unit 100. When the inspection switch on the car is turned off and the inspection operation mode is released, the worker detection unit 70 determines a detection signal indicating that the worker P1 is not working on the car 10. Output to the unit 100. In addition to the car inspection switch, the car top switch box includes a car safety switch, car door opening / closing switch, car top operation switch, top securing lighting switch, etc., and these switches are combined to provide the operator P1. It may be determined whether or not the car is working on the car 10.

  In a mode other than the normal operation mode in which call registration is performed by operating the platform control panel, for example, in the inspection operation mode, the operator detection unit 70 receives operation signals from various switches in the pit safety switch box and the car switch box. When it is not input, it is detected that the worker is working on the car 10 and at a place other than the pit.

  The approaching object position detection unit 80 detects the position of an approaching object that relatively approaches the worker. In the first embodiment, the approaching objects indicate the car 10 and the counterweight 20. The approaching object position detection unit 80 detects the positions of the car 10 and the counterweight 20. For example, the approaching object position detection unit 80 detects the number of rotations and the rotation direction of the motor by an encoder added to the motor of the hoisting machine 40, and based on the detected number of rotations and rotation direction of the motor, The positions of the car 10 and the counterweight 20 are detected. The approaching object position detection unit 80 outputs the detected positions of the car 10 and the counterweight 20 to the determination unit 100.

  The motion detection unit 90 detects that the motion is started at the time specified by the state of the elevator apparatus 2A and the motion command, and outputs the detection result to the determination unit 100. For example, in the inspection operation mode, when the car 10 is lowered by a certain amount at a specified start time, the operation detection unit 90 sends a detection signal indicating that the car 10 is lowered by a certain amount at the disclosure time to the determination unit 100. Output. When the car 10 rises by a certain amount at the designated start time, the motion detection unit 90 outputs a detection signal indicating that the car 10 rises by a certain amount at the disclosed time to the determination unit 100. The motion detection unit 90 and the approaching object position detection unit 80 constitute an approaching object detection unit.

  The determination unit 100 determines whether the approaching object approaches the worker P1 based on the detection results of the worker detection unit 70, the approaching object position detection unit 80, and the motion detection unit 90. For example, the determination unit 100 determines whether the car 10 approaches the worker P1 when the car 10 is lowered by a certain amount when the worker P1 is working in a pit. Further, when the worker P1 is working in the pit, the determination unit 100 determines whether or not the counterweight 20 approaches the worker P1 when the car 10 is raised by a certain amount. The determination unit 100 stores the determination result and the determination time in the approach determination time storage unit 110.

  The line-of-sight detection unit 120 detects the line of sight of the worker P1. For example, the line-of-sight detection unit 120 includes a glasses terminal device 121 and a line-of-sight determination unit 122. The glasses terminal device 121 is, for example, a glasses-type terminal device including an acceleration sensor, and is worn on the head of the worker P1 in the same manner as normal glasses. For example, when the operator P1 turns the line of sight in the direction of gravity with the glasses terminal device 121 mounted on the head of the worker P1, the glasses terminal device 121 has the line of sight of the worker P1 facing downward. A detection signal indicating this is output to the line-of-sight determination unit 122. Further, when the worker P1 turns his / her line of sight in the antigravity direction, the glasses terminal device 121 outputs a detection signal indicating that the line of sight of the worker P1 is facing upward to the line-of-sight determination unit 122.

  The line-of-sight determination unit 122 receives a detection signal from the glasses terminal device 121 and determines the line-of-sight direction of the worker P1 based on the input detection signal. The line-of-sight determination unit 122 stores the result of determining the line-of-sight direction of the worker P1 and the determined time in the line-of-sight determination time storage unit 130.

  Note that the device that detects the line of sight of the worker P1 is not limited to the glasses terminal device 121. For example, an external camera device (not shown) may be used. For example, a camera device is installed in the pit, the face of the worker P1 in the pit is photographed by the camera device, and image data of the photographed face is transmitted to the line-of-sight determination unit 122. The line-of-sight determination unit 122 receives image data from the camera device, and determines the face direction of the worker P1 based on the received image data. Then, the line-of-sight determination unit 122 determines the line-of-sight direction of the worker P1 from the direction of the face of the worker P1. For example, if the face direction of the worker P1 is downward (gravity direction), the line-of-sight determination unit 122 determines that the line-of-sight direction of the worker P is facing downward, and the face direction of the worker P1 is If it is upward (antigravity direction), it is determined that the line-of-sight direction of the worker P is facing upward.

  The notification unit 140 notifies the worker P1 that an approaching object is approaching. For example, the notification unit 140 is a buzzer, a vibration member, a warning light, or the like, or a combination thereof, and can be sensed by the worker P1 by auditory sense, tactile sense, visual sense or the like. The notification unit 140 is carried by the worker P1. The notification unit 140 may be installed on the car 10 or in the hoistway 60 such as a pit.

  The control unit 150 controls the notification unit 140 based on the determination result of the determination unit 100 and the detection result of the line-of-sight detection unit 120. The control unit 150 refers to the approach determination time storage unit 110 and the line-of-sight determination time storage unit 130, and the determination unit 100 determines that the approaching object, that is, the car 10 or the counterweight 20 is approaching the worker P1, and When it is detected by the line-of-sight detection unit 120 that the line of sight is not directed to the car 10 or the counterweight 20 that the worker P1 approaches, the notification unit 140 notifies the worker P1 of the car 10 or the counterweight 20. Announce the approach.

  Next, an operation example of the elevator maintenance work support device according to the first embodiment will be described. FIG. 2 is a flowchart illustrating an operation example of the elevator maintenance work support device according to the first embodiment. In order to perform maintenance and inspection of the elevator apparatus 2A, it is assumed that the normal operation mode is switched to the inspection operation mode.

  First, the worker detection unit 70 detects the position of the worker P1 (step S1). For example, the worker detection unit 70 is working whether the worker P1 is working in the pit of the hoistway 60, is working on the car 10, or is working elsewhere. To detect. For example, the worker detection unit 70 detects that the worker P1 is working in the pit when an operation signal output by operating various switches of the pit safety switch box is input by the worker P1. The signal is output to the determination unit 100.

  Next, the approaching object position detection unit 80 detects the positions of the car 10 and the counterweight 20 (step S2). For example, the approaching object position detection unit 80 detects the positions of the car 10 and the counterweight 20 in the hoistway 60 based on the rotation speed and rotation direction of the motor of the hoisting machine 40. The approaching object position detection unit 80 outputs the detected positions of the car 10 and the counterweight 20 to the determination unit 100.

  Next, the operation detection unit 90 acquires the operation command and start time of the elevator apparatus 2A (step S3). For example, the operation detection unit 90 acquires that the car 10 is lowered by a certain amount at the start time specified in the inspection operation mode, and outputs the acquired information to the determination unit 100.

  Next, the determination unit 100 determines whether or not the car 10 or the counterweight 20 approaches the worker P1 (Step S4). For example, when the worker P1 is working in a pit and the car 10 is lowered by a certain amount in a state where the car 10 is positioned in the vicinity of the pit, the determination unit 100 moves the car 10 to the worker P1. It determines with approaching (step S4: YES). In addition, when the worker P1 is working in the pit, the determination unit 100 does not approach the worker P1 even if the car 10 is not positioned in the vicinity of the pit and the car 10 is lowered by a certain amount, for example. In this case, it is determined that the car 10 does not approach the worker P1 (step S4: NO).

  When it is determined that the car 10 or the counterweight 20 approaches the worker P1, the control unit 150 determines whether or not the line of sight of the worker P1 is directed toward the car 10 or the counterweight 20 ( Step S5). For example, the control unit 150 refers to the line-of-sight determination time storage unit 130 and acquires the line-of-sight direction of the worker P1 and the determination time from the line-of-sight determination unit 122. Then, for example, when the car 10 descends a certain amount and approaches the worker P1, the control unit 150 determines whether or not the line of sight of the worker P1 is directed toward the car 10. When the control unit 150 determines that the line of sight of the worker P1 is not directed toward the car 10 (step S5: YES), the control unit 150 controls the notification unit 140 to confirm that the car 10 is approaching the worker P1. Notification is made (step S6). Further, when the control unit 150 determines that the line of sight of the worker P1 is directed toward the car 10 (step S5: NO), the control unit 150 does not notify the worker P1 that the car 10 is approaching.

  As described above, according to the elevator maintenance work support device 1A according to the first embodiment, the control unit 150 determines that the car 10 or the counterweight 20 approaches the worker P1 by the determination unit 100, and the line of sight When the detection unit 120 detects that the worker P1 is not looking toward the approaching car 10 or the counterweight 20, the notification unit 140 approaches the operator P1 from the car 10 or the counterweight 20 Is notified.

  As a result, when the operator P1 is not aware that the car 10 or the counterweight 20 is approaching the worker P1 during the maintenance and inspection work of the elevator apparatus 2A, the car 10 or the fishing car is moved to the worker P1. The approach of the weight 20 can be notified. Therefore, it can be avoided that the car 10 or the counterweight 20 contacts the worker P1. Further, when the worker P1 notices that the car 10 or the counterweight 20 is approaching, the operator P1 is not notified, so there is no trouble.

[Embodiment 2]
Next, a configuration example of the elevator maintenance work support device according to the second embodiment will be described. FIG. 3 is a schematic diagram illustrating a configuration example of an elevator maintenance work support device according to the second embodiment. As shown in FIG. 3, the second embodiment is different from the first embodiment in that it includes a collaborator P2. The joint worker P2 is a worker who performs work at the same place as the worker P1. For example, when the worker P1 is working in the pit, the collaborator P2 is also working in the pit. In the second embodiment, the line-of-sight direction of the collaborator P2 is not detected.

  As with the worker P1, the collaborator P2 also carries the notification unit 140. The notification unit 140 notifies the worker P1 and the collaborator P2 that the car 10 or the counterweight 20 is approaching. In addition, you may make it alert | report to the worker P1 and the collaborator P2 by installing the alerting | reporting part 140 on the passenger car 10 or in a pit.

  Next, an operation example of the elevator maintenance work support device according to the second embodiment will be described. FIG. 4 is a flowchart illustrating an operation example of the elevator maintenance work support apparatus according to the second embodiment. In order to perform maintenance and inspection of the elevator apparatus 2A, it is assumed that the normal operation mode is switched to the inspection operation mode. Note that the processing from step S1 to S6 shown in FIG. 4 is the same as the processing from step S1 to S6 shown in FIG.

  First, the worker detection unit 70 detects the position of the worker P1 (step S1), and then the approaching object position detection unit 80 detects the positions of the car 10 and the counterweight 20 within the hoistway 60. (Step S2). Next, the motion detection unit 90 acquires the operation command and start time of the elevator apparatus 2A (step S3), and then the determination unit 100 determines whether the car 10 or the counterweight 20 approaches the worker P1. It is determined whether or not (step S4). When it is determined that the car 10 or the counterweight 20 is approaching the worker P1 (step S4: YES), the line-of-sight detection unit 120 causes the line of sight of the worker P1 to approach the car 10 or the counterweight 20 that approaches. It is determined whether or not it is directed (step S5). For example, when the control unit 150 determines that the line of sight of the worker P1 is not directed to the approaching car 10 (step S5: YES), the control unit 150 controls the notification unit 140 so that the car 10 approaches the worker P1. It is notified (step S6).

  Next, the control unit 150 determines whether or not there is a collaborator P2 (step S7). For example, when the collaborator P2 carries the notification unit 140, the control unit 150 receives an activation signal indicating that the notification unit 140 of the collaborator P2 is activated. When receiving the activation signal of the notification unit 140 other than the worker P1, the control unit 150 determines that the collaborator P2 is present (step S7: YES), and notifies the notification unit 140 of the collaborator P2 who has transmitted the activation signal. To notify that the car 10 is approaching (step S8). In addition, when the activation signal of the notification unit 140 is not received other than the worker P1, the control unit 150 determines that there is no joint worker P2 (step S7: NO), and other than the notification unit 140 of the worker P1. Notification control is not performed.

  As described above, according to the elevator maintenance work support device 1B according to the second embodiment, when the worker P1 does not notice that the car 10 or the counterweight 20 is approaching, the collaborator P2 is informed. In contrast, the fact that the car 10 or the counterweight 20 is approaching is also notified.

  Thereby, when the worker P1 is not aware that the car 10 or the counterweight 20 is approaching, the worker P1 can notice the approach from the collaborator P2. Therefore, it can avoid more reliably that the passenger car 10 or the counterweight 20 contacts the worker P1 and the collaborator P2.

  Also, when the collaborator P2 does not work in the same pit as the worker P1 and operates the hall maintenance unit at the landing to drive the car 10, the collaborator P2 at the landing A notification unit (not shown) notifies that the car 10 or the counterweight 20 is approaching the worker P1. Thereby, the joint worker P2 can stop the operation of the car 10, and the car 10 can be prevented from coming into contact with the worker P1.

  In addition, although the joint worker P2 demonstrated the example of one person, the joint worker P may be plural. In this case, the notification unit 140 is also carried by other collaborators P2 as well as the collaborator P2.

[Embodiment 3]
Next, a configuration example of the elevator maintenance work support device according to the third embodiment will be described. FIG. 5 is a schematic diagram illustrating a configuration example of an elevator maintenance work support device according to the third embodiment. As shown in FIG. 5, the third embodiment is different from the second embodiment in that the elevator apparatus 2 </ b> B includes a moving body stopping unit 160. The moving body stop unit 160 stops the movement of the car 10 and the counterweight 20. For example, the moving body stop unit 160 stops the rotation of the motor of the hoisting machine 40 based on the control of the control unit 150, and stops the raising and lowering of the car 10 and the counterweight 20.

  Next, an operation example of the elevator maintenance work support device according to the third embodiment will be described. FIG. 6 is a flowchart illustrating an operation example of the elevator maintenance work support apparatus according to the third embodiment. In order to perform maintenance and inspection of the elevator apparatus 2B, it is assumed that the normal operation mode is switched to the inspection operation mode. In addition, the process of step S1 to S8 shown in FIG. 6 is the same process as step S1 to S8 shown in FIG.

  First, the worker detection unit 70 detects the position of the worker P1 (step S1), and the approaching object position detection unit 80 detects the positions of the car 10 and the counterweight 20 (step S2), and detects the operation. The unit 90 acquires the operation command and start time of the elevator apparatus 2B (step S3).

  The determination unit 100 determines that the car 10 or the counterweight 20 approaches the worker P1 (step S4: YES), and the line-of-sight detection unit 120 has the line of sight of the worker P1 directed toward the car 10. When it determines with there being no (step S5: YES), the alerting | reporting part 140 alert | reports to the worker P1 and the joint worker P2, and the moving body stop part 160 after that, the movement of the passenger car 10 and the counterweight 20 is carried out. Stop (step S9).

  As described above, according to the elevator maintenance work support device 1C according to the third embodiment, the control unit 150 determines that the car 10 or the counterweight 20 approaches the worker P1 by the determination unit 100, and the line of sight When it is detected by the detection unit 120 that the worker P1 is not looking at the car 10 or the counterweight 20, the moving body stop unit 160 stops the movement of the car 10 and the counterweight 20. is there.

  Thereby, it can avoid more reliably that the passenger car 10 or the counterweight 20 approaches the operator P1, and the elevator car 10 or the counterweight 20 contacts the operator P1. Even if the worker P1 is not aware of the buzzer sounding by the notification unit 140, the car 10 or the counterweight 20 can be prevented from approaching the worker P1.

[Embodiment 4]
Next, a configuration example of the elevator maintenance work support device according to the fourth embodiment will be described. FIG. 7 is a schematic diagram illustrating a configuration example of an elevator maintenance work support device according to the fourth embodiment. As shown in FIG. 7, the fourth embodiment is different from the third embodiment in that it includes an elevator apparatus 2 </ b> C of another car (Y car). The elevator apparatus 2C of the No. Y machine is installed in the same bank as the elevator apparatus 2B of the No. X machine, and the approaching object of the other No. 2 which is relatively close to the worker P1, that is, the elevator car 2 and the counterweight 20 of the elevator apparatus 2C. The approaching object position detection part 80C of the other car is detected. The approaching object position detection unit 80C and the motion detection unit 90C of the other car constitute an approaching object detection unit.

  Next, an operation example of the elevator maintenance work support device according to the fourth embodiment will be described. FIG. 8 is a flowchart illustrating an operation example of the elevator maintenance work support apparatus according to the fourth embodiment. The elevator apparatus 2B is switched from the normal operation mode to the inspection operation mode in order to perform maintenance and inspection, and the elevator apparatus 2C is premised on the normal operation being performed. Note that steps S1 to S9 shown in FIG. 8 are the same processes as steps S1 to S9 shown in FIG.

  First, the worker detection unit 70 detects the position of the worker P1 (step S1). Next, the approaching object position detection unit 80 detects the positions of the car 10 and the counterweight 20 of the elevator apparatus 2B of the No. X machine (step S2), and the operation detection unit 90 operates the operation of the elevator apparatus 2B of the No. X machine. The command and start time are acquired (step S3). Next, the approaching object position detection unit 80C of the other unit detects the positions of the car 10 and the counterweight 20 of the elevator unit 2C of the Y unit (step S2A), and the operation detection unit 90C detects the elevator unit of the Y unit. A 2C operation command and start time are acquired (step S3A).

  Next, the determination unit 100 determines whether the elevator car 2B, 2C elevator 10 or counterweight 20 of the No. X and No. Y machines approaches the worker P1 (step S4). When the determination unit 100 determines that the elevator car 2 or the counterweight 20 of the elevator devices 2B or 2C approaches the worker P1 (step S4: YES), the line-of-sight detection unit 120 determines that the line of sight of the worker P1 is approaching. It is determined whether or not the elevator apparatus 2B or 2C is directed to the car 10 or the counterweight 20 (step S5). When it is determined by the line-of-sight detection unit 120 that the line of sight of the worker P1 is not directed to the car 10 or the counterweight 20 of the approaching elevator devices 2B and 2C (step S5: YES) Then, the notification unit 140 is controlled to notify the worker P1 that the passenger car 10 or the counterweight 20 of the elevator apparatuses 2B and 2C is approaching (step S6). Here, the moving speed of the elevator car 2 or the counterweight 20 of the elevator apparatus 2C in the normal operation mode is faster than the moving speed of the elevator car 2 or the counterweight 20 of the elevator apparatus 2B in the inspection operation mode. For this reason, when the car 10 etc. of the elevator apparatus 2C is approaching the worker P1, the timing notified when the car 10 etc. of the elevator apparatus 2B approaches the worker P1 is set earlier. Thereby, it can avoid reliably that the car 10 grade | etc., Of the elevator apparatus 2C contacts the operator P1.

  Next, the control unit 150 determines whether or not there is a collaborator P2 (step S7). If it is determined that there is a collaborator P2 (step S7: YES), the notification unit 140 of the collaborator P2 is provided. , The notification unit 140 is controlled to notify that the elevator car 2B, 2C of the car 10 or the counterweight 20 is approaching (step S8). The moving body stopping unit 160 stops the movement of the elevator car 2B, 2C that is approaching and the counterweight 20 (step S9).

  As described above, according to the elevator maintenance work support device 1D according to the fourth embodiment, the determination unit 100 uses the elevator car 2 and the counterweight 20 of the elevator device 2C detected by the approaching object position detection unit 80C of the other car. In consideration of this, it is determined whether or not the car 10 or the counterweight 20 approaches the worker P1. The controller 150 determines that at least one of the elevator car 2 or the counterweight 20 of the elevator apparatuses 2B and 2C approaches the worker P1 by the determination unit 100, and the elevator apparatus 2B by the line-of-sight detection unit 120. , 2C, when it is detected that the worker P1 is not looking at the approaching car 10 or the counterweight 20, the notification unit 140 notifies the worker P1 (joint worker P2).

  As a result, the worker P1 (joint worker P2) is not aware that the elevator car 2 or the counterweight 20 of the elevator apparatus 2C of the other car installed in the same bank is approaching the worker P1. Also about the case, it can alert | report that the passenger car 10 or the counterweight 20 of the elevator apparatus 2C of another number machine is approaching the worker P1 (joint worker P2).

[Embodiment 5]
Next, a configuration example of the elevator maintenance work support device according to the fifth embodiment will be described. FIG. 9 is a schematic diagram illustrating a configuration example of an elevator maintenance work support device according to the fifth embodiment. In the fifth embodiment, as shown in FIG. 9, when the worker P1 works on the car 10, the worker P1 is placed on a fixed object 171 installed in the hoistway 60, such as a control panel (not shown). It differs from Embodiment 4 in the point which determines whether it approaches. The elevator apparatuses 2D and 2E include a fixed object detection unit 170. The fixed object detection unit 170 detects the position of the fixed object 171 in the hoistway 60 within a certain distance from the worker P1 who moves with the car 10. For example, the fixed object detection unit 170 detects the position of the fixed object 171 in the hoistway 60 in advance.

  Next, an operation example of the elevator maintenance work support device according to the fifth embodiment will be described. FIG. 10 is a flowchart illustrating an operation example of the elevator maintenance work support apparatus according to the fifth embodiment. In order to perform maintenance and inspection of the elevator apparatuses 2D and 2E, it is assumed that the elevator apparatus 2D is switched from the normal operation mode to the inspection operation mode, and the elevator apparatus 2E is operated in the normal operation mode. Note that steps S1 to S9, S2A, and S3A shown in FIG. 10 are the same processes as steps S1 to S9, S2A, and S3A shown in FIG.

  First, the worker detection unit 70 detects the position of the worker P1 (step S1). Next, the approaching object position detecting unit 80 detects the positions of the car 10 and the counterweight 20 of the elevator apparatus 2D of the X machine (step S2), and the operation detecting unit 90 operates the elevator apparatus 2D of the X machine. The command and start time are acquired (step S3). Next, the approaching object position detection unit 80C of the other car (Y car) detects the positions of the car 10 and the counterweight 20 of the elevator apparatus 2E of the Y car (step S2A). The operation command and start time of the elevator apparatus 2E of the number machine are acquired (step S3A).

  Next, the determination unit 100 determines whether or not the worker P1 is on the elevator car 2D or 2E (step S30). For example, when the operator P1 inputs operation signals that are output when the operator P1 operates various switches in the switch box on the elevator car 2D, the operator P1 moves the car 10 of the elevator apparatus 2D. A detection signal indicating that the user is working is output to the determination unit 100. When a detection signal indicating that the worker P1 is working on the elevator car 2D of the elevator device 2D is input from the worker detection unit 70, the determination unit 100 detects that the worker P1 is on the elevator device 2D. It is determined that the work is performed on the car 10 (step S30: NO). If the detection signal indicating that the worker P1 is working on the elevator car 2D of the elevator device 2D is not input from the worker detection unit 70, the determination unit 100 detects that the worker P1 is the elevator device 2D. It is determined that no operation is performed on the car 10 (step S30: YES).

  When determining that the worker P1 is working on the car 10, the determining unit 100 determines whether the worker P1 approaches the fixed object 171 (step S4A). For example, the determination unit 100 is based on the position of the fixed object 171 in the hoistway 60 detected by the fixed object detection unit 170 of the elevator apparatus 2D and the position and moving direction of the car 10 of the elevator apparatus 2D. It is determined whether or not the worker P1 working on the car 10 approaches the fixed object 171.

  When it is determined that the worker P1 working on the car 10 does not approach the fixed object 171 (step S4A: NO), the notification is not performed and the process is terminated. When it is determined that the worker P1 working on the car 10 approaches the fixed object 171 (step S4A: YES), the determination unit 100 determines whether the line of sight of the worker P1 is directed to the fixed object 171. It is determined whether or not (step S5A). For example, the control unit 150 refers to the line-of-sight determination time storage unit 130 and acquires the line-of-sight direction of the worker P1 and the determination time from the line-of-sight determination unit 122. Then, for example, the control unit 150 determines whether or not the line of sight of the worker P1 is directed toward the fixed object 171 when the car 10 is raised by a certain amount. When the control unit 150 determines that the line of sight of the worker P1 is not directed toward the fixed object 171 (step S5A: YES), the control unit 150 controls the notification unit 140 to confirm that the fixed object 171 is approaching the worker P1. Notification is made (step S6A). If the control unit 150 determines that the line of sight of the worker P1 is directed toward the fixed object 171 (step S5A: NO), the control unit 150 ends without notifying the worker P1 that the fixed object 171 is approaching. It becomes. When there is a collaborator P2 (step S7A: YES), the notification unit 140 is controlled so as to notify the collaborator P2 that the fixed object 171 is approaching (step S8A), and then the moving body is stopped. The movement of the passenger car 10 and the counterweight 20 is stopped by the unit 160 (step S9).

  As described above, according to the elevator maintenance work support device 1E according to the fourth embodiment, the control unit 150 determines that the worker P1 approaches the fixed object 171 by the determination unit 100 and performs the work by the line-of-sight detection unit 120. When it is detected that the person P1 does not direct his / her line of sight to the fixed object 171, the notification unit 140 notifies the worker P1 (joint worker P2) of the approach of the fixed object 171.

  As a result, when the operator P1 who is working on the car 10 is not aware that the fixed object 171 is approaching during the maintenance work of the elevator, the worker P1 approaches the fixed object 171. Can be informed. Therefore, the worker P1 can be prevented from coming into contact with the fixed object 171. Further, when the worker P1 is aware that the worker P1 is approaching the fixed object 171, the worker P1 is not notified, so there is no trouble. The notification can be similarly made to the collaborator P2 who is working on the car 10. Note that when the worker P1 works on the car 10, it may be determined whether or not the worker P1 approaches the counterweight 20 in addition to the fixed object 171.

[Embodiment 6]
Next, a configuration example of the elevator maintenance work support device according to the sixth embodiment will be described. FIG. 11 is a schematic diagram illustrating a configuration example of an elevator maintenance work support device according to the sixth embodiment. As shown in FIG. 11, the sixth embodiment differs from the fifth embodiment in that a determination invalidation unit 180 is provided. The determination invalidation unit 180 invalidates the function of the determination unit 100 by a predetermined operation of the worker P1.

  Next, an operation example of the elevator maintenance work support device according to the sixth embodiment will be described. FIG. 12 is a flowchart illustrating an operation example of the elevator maintenance work support apparatus according to the sixth embodiment. In order to perform maintenance and inspection of the elevator apparatuses 2D and 2E, it is assumed that the elevator apparatus 2D is switched from the normal operation mode to the inspection operation mode, and the elevator apparatus 2E is operated in the normal operation mode. The processing is the same as that shown in FIG. 10 except for step S01 shown in FIG.

  First, the determination invalidation unit 180 determines whether the approach determination function for determining that the car 10, the counterweight 20 and the fixed object 171 approach the worker P1 is valid or invalid (step) S01). The worker P1 can switch the approach determination function between valid and invalid by a switch or the like (not shown). If the determination invalidation unit 180 determines that the approach determination function is enabled by the worker P1 (step S01: YES), the worker detection unit 70 detects the position of the worker P1 (step S1). ), A process of informing when an approaching object such as the car 10 approaches the worker P1 and the worker P1 is not aware of it. Further, if the determination invalidation unit 180 determines that the approach determination function is disabled by the worker P1 (step S01: NO), an approaching object such as the car 10 approaches the worker P1 and works. The process of notifying when the person P1 is not aware is not performed.

  As described above, according to the elevator maintenance work support device 1F according to the sixth embodiment, the approach determination function can be disabled by the worker P1, so that the approaching object such as the car 10 approaches the worker P1. When there is no need to do so, there is no need to make unnecessary notifications. For example, if it is known in advance that an approaching object such as the car 10 approaches the worker P1 but does not come into contact with the worker P1, if the approach determination function is set to be invalid, unnecessary notification is not required. Thereby, the troublesomeness at the time of work can be eliminated. Note that the approach determination function may be disabled only for those who have the authority not to include the worker P1.

  The direction of the line of sight of the worker P1 is detected, and notification is given when the worker P1 is not aware that the car 10 or the counterweight 20 is approaching. Detection may be performed when the collaborator P2 is not aware that the car 10 or the counterweight 20 is approaching. Further, the direction of the line of sight of the worker P1 and the collaborator P2 is detected, and notification is given when the worker P1 or the collaborator P2 is not aware that the car 10 or the counterweight 20 is approaching. It may be.
