DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the first embodiment of the present invention will be described below with reference to FIG. First Embodiment FIG. 1 is a diagram showing a first embodiment of the present invention.

In FIG. 1, reference numeral 6 denotes a central monitoring center having an inspection command execution command and an inspection command program for receiving an inspection result, and is connected to the elevator controller 12 by a communication line such as a telephone line. . 7 is I /
O port, 8 RAM, 9 CPU, 10 ROM, 1
Reference numeral 1 is a computer including I / O ports 7 to ROM 10.

Further, 12 is an elevator controller having an inspection program which operates according to a remote command from the central monitoring center 6 and reports the inspection result to the central monitoring center 6 and an operation program for controlling the elevator based on the program. And I / O port 13 and RAM
14, a computer 17 having a CPU 15 and a ROM 16.

Further, 3 is an elevator body composed of a car, which is driven by a hoisting machine 20 operated by an electric motor 18.
Reference numeral 19 is an encoder mounted on the hoisting machine 20, for example, for measuring the braking distance when the elevator is landing on the floor, and for checking the operating condition of a braking device (not shown). Reference numeral 21 is a car door mounted on the lift 22. It is an optical sensor composed of a photocoupler for measuring the opening / closing speed (not shown) and checking the operating condition of the car door.

Next, the operation of the first embodiment of the present invention will be described with reference to FIGS. FIG. 2 is a flowchart showing an inspection command program of the central monitoring center 6. Further, FIG. 3 is a flowchart showing an inspection program for the elevator control device 12.

First, the operation of the inspection command program will be described. In step 31, the inspection command program which is automatically started at a predetermined date and time creates inspection command data. That is, since a plurality of elevators are inspected and managed, for example, inspection command data including a control number for each building, a machine number, inspection items such as elevator braking distance and door opening / closing time, and an inspection command command are created. To do.

In step 32, the inspection command data is transmitted to the elevator controller 12 through the communication line.

In steps 33 to 34, the inspection result data from the elevator control device 12 to be managed is received through the communication line and printed out in a predetermined format. It should be noted that the display device such as a CRT may display the images independently or simultaneously.

Next, the operation of the inspection command program will be described. For example, in step 41, if the elevator is in operation, the process proceeds to step 42. If there is an inspection execution command from the central monitoring center, the process proceeds to step 43. If there is no execution command, the process proceeds to step 47. Operation continues.

In step 43, the inspection is carried out for the designated inspection item. For example, the encoder 19 is used to operate the elevator at a specified speed, measure the braking distance after the stop command, and check the operation status of the braking device. That is, the braking distance is calculated by counting the pulses from the encoder 19 after the stop command and compared with a predetermined braking distance reference value stored in the RAM 14 to find a malfunction of the braking device.

Further, for example, using the optical sensor 21,
Check the operation status of the car door by measuring the opening / closing speed of the car door. That is, the opening / closing speed of the car door is calculated by detecting the signal from the optical sensor 21 after the opening / closing command, and R
A defect or the like of the car door is found by comparing with a predetermined opening / closing speed reference value stored in the AM 14.

In step 44, the inspection result of step 43 is stored in the RAM 14. And step 4
If the next inspection item is designated in step 6, step 43
Then, the same operation is performed thereafter, and unless otherwise specified, in step 46, the stored contents of the inspection result obtained in step 44 are reported, that is, transmitted to the central monitoring center 6.

The inspection items shown in steps 43 to 45 are examples, and the same operation can be expected with any other inspection item and inspection means. In addition, in the first embodiment, it is of course possible to output the inspection result not only to the central monitoring center 6 but also to the display device directly connected to the elevator control device 12.

By the above operation, the inspection result of the designated item is reported to the central monitoring center 6 by the inspection program installed in the elevator control device 12 according to the remote execution command from the central monitoring center 6. Therefore,
Efficient maintenance is possible because the inspection result information can be obtained without having to go to the site where the elevator is located.

The first embodiment of the present invention, as described above,
It is an object of the present invention to obtain an elevator inspection device capable of inspecting an elevator by a remote command and confirming the inspection result at the central monitoring center 6. Therefore, it operates by a remote command from the central monitoring center 6, and the encoder 19 and the optical sensor 2 are operated.
Central monitoring having an inspection control program for transmitting an inspection result obtained from 1 etc. and an operation program for controlling an elevator, and an inspection command program for receiving the inspection command execution command and the inspection result. Establish a center 6. Therefore, there is no need to bother to go to the site where the elevator is located, and it is possible to perform efficient maintenance.

[0025]

As described above, according to the present invention, since the elevator can be inspected based on the instruction from the central monitoring center and the inspection result can be received by the central monitoring center, it is troublesome to go to the site where the elevator is located. It has an effect that it is possible to perform efficient maintenance without any trouble.
