Description

  The present invention relates to an elevator monitoring apparatus and method for monitoring an elevator, and more particularly to an elevator monitoring apparatus and an elevator monitoring method for monitoring a car that has stopped abnormally using a drone with a camera.

  If one of multiple elevators in parallel breaks down and the car stops between the floors, move the car in the adjacent elevator to the same height as the stopped car, and then rescue the car There is known a method of docking each other to rescue a passenger in a stop side car to a rescue side car. However, if there is an obstacle such as a beam before the rescue exit of the stop-side car, the rescue exits cannot be docked with each other, and passengers may not be rescued from the rescue exit.

  On the other hand, in Patent Document 1, a reflector corresponding to the position of the obstacle is provided in advance on the wall of the hoistway, and when the obstacle detector of the stop-side car detects the reflector, the obstacle is detected before the rescue exit. When it is judged that there is an object and it is not detected, it is judged that there is no obstacle before the rescue exit, so that it is possible to determine whether the rescue exits can be docked before starting the rescue car. .

Japanese Utility Model Publication No. 5-40267

  However, in Patent Document 1, it is necessary to install a reflector for each obstacle and for each elevator. For example, even in the range shown in FIG. A total of four reflectors are provided on the right wall surface. That is, since Patent Document 1 has a configuration in which the number of reflectors increases in proportion to the number of obstacles, the number of reflectors installed increases as the building becomes taller and the number of obstacles such as beams increases, and the cost required for obstacle detection increases. There is a problem of increasing.

  Therefore, the present invention makes it possible to easily check whether there is an obstacle before the rescue exit of the stop-side car, even in a high-rise building elevator, with a cost-saving configuration without using a large amount of obstacle detection means. An object is to provide an elevator monitoring device and an elevator monitoring system that can be distinguished.

  In order to solve the above-described problems, in the elevator monitoring device of the present invention, the first elevator car that moves up and down the first hoistway and includes a rescue exit on the side of the second hoistway provided side by side, A first control means for controlling raising and lowering of the car, a second car that raises and lowers the second hoistway, and has a rescue exit on the first hoistway side, and the second car An elevator monitoring device that monitors the second control means for controlling the raising and lowering, and when one of the cars is abnormally stopped between the floors, it is started with respect to the drone with a camera mounted on one of the cars Allow or command

  According to the present invention, an elevator monitoring device that can easily determine the presence or absence of an obstacle before a rescue exit of a stop-side car, without using a large amount of obstacle detection means, and an elevator monitoring A system can be provided.

1 is a schematic diagram of an elevator monitoring system according to a first embodiment. The flowchart which shows until the rescue operation | work start of Example 1. FIG. The flowchart which shows until the rescue operation | work start of Example 2. FIG.

  Hereinafter, an elevator monitoring apparatus and an elevator monitoring system according to an embodiment of the present invention will be described with reference to FIGS. 1 to 3.

  FIG. 1 is a schematic diagram of an elevator monitoring system according to a first embodiment of the present invention, and shows an elevator monitoring system that can monitor and control the operation of two elevators and a drone with one monitoring device.

  As shown here, the No. 1 elevator provided in the left hoistway includes a car 1a, a counterweight 5a, a main rope 3a connecting them at both ends, a hoisting machine 7a for driving the main rope 3a, and a hoisting machine 7a and the like, and a landing door 13a provided in the elevator hall of each floor, a car door 11a on the landing side of the car 1a, and a rescue outlet 15a on the right hoistway side. . Note that a drone 31 described later is mounted on the car 1a.

  Similarly, the No. 2 elevator provided in the right hoistway includes a car 1b, a counterweight 5b, a main rope 3b connecting them at both ends, a hoisting machine 7b for driving the main rope 3b, a hoisting machine 7b, and the like. The control apparatus 9b to control and the landing door 13b provided in the elevator hall of each floor are provided, The car door 11b is provided in the boarding side of the car 1b, and the rescue exit 15b is provided in the left hoistway side. In the following description, the car 1b without the drone 31 will be described as an example. However, the drone 31 may be mounted on the car 1b.

  Further, the elevator monitoring device 21 monitors and controls the control devices 9a and 9b via the local line 22 including a wired part or a wireless part, and controls a drone 31 to be described later. The maintenance terminal 23 is a terminal operated by a worker when the elevator is maintained and inspected. The elevator monitoring device 21 and the maintenance terminal 23 are connected to a remote monitoring center 25 via a public line 24 including a wired portion or a wireless portion. The monitoring center 25 is connected to the elevator monitoring device 21 or the maintenance terminal 23. Through which the operation of each elevator is monitored.

  Here, since there are a plurality of obstacles 17 such as beams between the left and right hoistways, when any of the cars 1 abnormally stops between the floors, the obstacle 17 is placed before the rescue exit 15. In some cases, even if the operating car 1 is sent to rescue, the rescue ports 15 cannot be docked with each other, and passengers cannot be rescued from the rescue port 15. Therefore, in this embodiment, a drone 31 with a camera is used to confirm the presence or absence of the obstacle 17 in front of the rescue exit 15.

  The drone 31 is operated by the controller 32 or the elevator monitoring device 21 operated by the worker, and the captured image is transferred to the video display device 33 or the monitoring center 25 attached to the controller 32 via the local line 22 or the public line 24. To be sent. The video imaged by the drone 31 is analyzed by a worker or the monitoring center 25 to determine the presence or absence of an obstacle in front of the rescue exit 15. When the monitoring center 25 determines the presence or absence of the obstacle 17 in front of the rescue exit 15, the rescue center 15 of the stop-side cage 1 is photographed from the hoistway of the operation-side elevator 1, and before the rescue exit 15 is obtained. The presence or absence of the obstacle 17 in front of the rescue exit 15 is determined by performing image analysis to determine whether there is a foreign object crossing the road.

  The drone 31 is provided with a flashlight, an infrared camera, etc. for photographing inside the dark hoistway. Further, a charging terminal may be provided in the car 1a so that the drone 31 before starting can be charged via the charging terminal.

  Here, using the flowchart of FIG. 2, the car 1a (No. 1) equipped with the drone 31 abnormally stops between the floors, while the car 1b (No. 2) not equipped with the drone 31 can be operated. The rescue operation of passengers in the car 1a will be described.

  First, when the car 1a stops abnormally for some reason (S201), the stop position information is transmitted to the elevator monitoring device 21 and the monitoring center 25 via the control device 9a. As a result, the stop position of the car 1a can be confirmed even at the maintenance terminal 23 connected to the monitoring center 25 or the monitoring center 25 (S202).

  Then, it is determined whether or not the abnormal stop position of the car 1a has been confirmed (S203). If it cannot be confirmed, the monitoring center 25 or maintenance terminal is used so that the drone 31 in flight and the car 1b in operation do not collide. 23 sends a command to move the car 1b to the lowest floor and wait for it to the control device 9b (S204).

  On the other hand, when the abnormal stop position of the car 1a can be confirmed, the control device 9b is controlled from the elevator monitoring device 21, the monitoring center 25, or the maintenance terminal 23 so that the flying drone 31 and the operating car 1b do not collide. In response to this, a command for restricting the traveling range of the car 1b and prohibiting driving in the vicinity of the car 1a is sent (S205). At this time, the operating car 1b may be provided for passenger use, or the passenger use may be stopped in preparation for a rescue operation to be performed later.

  After the elevator monitoring device 21 permits the start of the drone 31 through the above processing, the drone 31 is activated by a command from the elevator monitoring device 21 or the controller 32, and is allowed to fly from the car 1a (S206) and stopped. A video around the car 1a is photographed (S207). As described above, the video image taken by the drone 31 is sent to the monitoring center 25 and the video display device 33, and the presence or absence of the obstacle 17 in front of the rescue exit 15a is confirmed (S208).

  If there is no obstacle 17 in front of the rescue exit 15a of the car 1a, it is judged that rescue from the rescue exit 15a of the car 1a is possible (S209). If there is an obstacle 17 in front of the rescue exit 15a, the rescue is performed. It is determined that rescue from the exit 15a is not possible (S210).

  Then, the drone 31 is operated by the elevator monitoring device 21 or the controller 32, and the inside of the hoistway from the car 1a to the landing door 13a on the nearest floor is photographed, and the landing door on the nearest floor from the stop position of the car 1a. By grasping the distance to 13a, the distance required to move the car 1a to the nearest landing door 13a by releasing the brake is confirmed (S211).

  And after confirming the presence or absence of obstacles in S208 and confirming the distance traveled to the nearest floor in S211, as a passenger rescue method, it is better to send the car 1b to rescue, or by releasing the brake It is determined whether it is better to move the car 1a to the nearest floor (S212). In general, it is desirable to select the person who can complete the rescue operation in a shorter time. However, if it is confirmed from the shooting in the hoistway that it is difficult to move the car 1a or the car 1b. A rescue method for raising and lowering the car 1 that can be easily raised and lowered may be employed.

  After the rescue method is determined, the drone 31 is accommodated in a predetermined position (S213). At this time, the drone 31 started from the car 1a may be accommodated in the car 1b. Next, from the monitoring center 25 or the maintenance terminal 23, a command for canceling the travel range restriction of the car 1b is sent to the control device 9b (S214). And the passenger in the car 1a is rescued using the rescue method determined in S212.

  According to the present embodiment described above, it is possible to check the presence or absence of an obstacle before the rescue exit of the car that has stopped abnormally with the captured video of the drone, so it is possible to quickly determine the appropriate rescue method for passengers in the car It is possible to shorten the time required for rescue. Further, by restricting the operating range of the elevator on the operating side before the drone is activated, it is possible to avoid collision between the drone in flight and the operating car.

  Next, the rescue operation flow in the elevator monitoring system of the second embodiment will be described using the flowchart of FIG. FIG. 2 of the first embodiment is an example in which the car 1a (unit 1) equipped with the drone 31 has stopped abnormally, and is an example in which the drone 31 is in the vicinity of the car 1a on the failure side from the beginning. In the example, the car 1b (No. 2) not equipped with the drone stops abnormally, and the distance between the drone 31 and the car 1b on the failure side is indefinite. In addition, duplication description is abbreviate | omitted in common with Example 1. FIG.

  First, when the car 1b stops abnormally for some reason (S301), the stop position information is transmitted to the elevator monitoring device 21 and the monitoring center 25 via the control device 9b. As a result, the stop position of the car 1b can be confirmed even at the maintenance terminal 23 connected to the monitoring center 25 or the monitoring center 25 (S302).

  Then, it is determined whether or not the abnormal stop position of the car 1b has been confirmed (S303), and if it cannot be confirmed, the monitoring center 25 or the maintenance terminal is used so that the flying drone 31 and the operating car 1a do not collide. 23 sends a command to move the car 1a to the lowest floor and wait for it to the control device 9a (S304).

  On the other hand, when the abnormal stop position of the car 1a can be confirmed, the current position of the car 1a which is an operating machine is confirmed (S305). When the car 1a on which the drone 31 is mounted is above the stopped car 1b, the car 1a is placed near the car 1b from the monitoring center 25 or the maintenance terminal 23 to the control device 9a (for example, , A descent command for moving the vehicle 1b to a position immediately below the nearest floor on the lower side of the car 1b is transmitted, and the car 1a is put on standby at a desired position (S306).

  Similarly, when the car 1a on which the drone 31 is mounted is below the stopped car 1b, the car 1a is placed near the lower side of the car 1b from the monitoring center 25 or the maintenance terminal 23 to the control device 9a ( For example, an ascending command for moving the vehicle 1b directly below the nearest floor on the lower side of the car 1b is transmitted, and the car 1a is put on standby at a desired position (S307).

  The drone 31 before starting is delivered to the vicinity of the car 1b that has stopped abnormally by either S306 or S307 shown here. Thereby, since the moving time of the drone 31 can be significantly reduced, most of the activity time can be used for photographing in the vicinity of the car 1b that has stopped abnormally. After the elevator monitoring device 21 permits the start of the drone 31 through the above processing, when the drone 31 is started (S308), the drone 31 is lifted slightly, and the vicinity of the car 1b that has stopped abnormally is detected. You can shoot. After the drone 31 starts, the operating car 1a may be provided for passenger use. In that case, the elevator monitoring device 21, the monitoring center 25, or the maintenance terminal is used to avoid collision with the drone 31. 23 sends a command for restricting the driving range of the car 1a and prohibiting driving in the vicinity of the car 1b to the control device 9a (S309).

  Note that the processing after S310 in FIG. 3 is the same as the processing after S207 in FIG.

  According to the present embodiment described above, in addition to the effects obtained in the first embodiment, since the drone can be delivered to the vicinity of the abnormally stopped car by the operating car, most of the driving time of the drone can be reduced. It can be used for shooting in the vicinity of a car that has stopped abnormally.
