Description

The present invention relates to an elevator maintenance device, and more particularly to an elevator maintenance device suitable for checking the operating state of an elevator from a remote location.

[Conventional technology]

Conventionally, for maintenance and inspection of elevators, maintenance personnel regularly visit the site where the elevator is actually installed, check the operating state of the elevator, and replace parts and repair failures.

However, in recent years, as described in Japanese Patent Laid-Open No. 59-22869, a data recording device that records the operating state data collected from the elevator, a timer device that operates the data recording device at the time of regular maintenance and inspection, An elevator maintenance device including a signal conversion unit for converting the operating state data of the elevator into a serial signal and transmitting the serial signal to a maintenance center, and an information processing device for receiving and processing the transmitted serial signal. Is proposed. That is, when the maintenance personnel operates the timer device during maintenance and inspection, the data recording device operates, and the operating state data of the elevator recorded therein is converted into a serial signal by the signal conversion means in the transmission device.
The data is transmitted to the maintenance center and processed by the information processing device. As a result, even in a remote location, the operating state of the elevator can be regularly grasped.

[Problems to be Solved by the Invention]

Since the conventional elevator maintenance device is configured as described above,
Only during regular maintenance and inspection, by transmitting a serial signal of elevator operating status data to the maintenance center, the operating status of the elevator can be grasped periodically from a remote location. Most of them are abnormalities during normal service, and most of these abnormalities are not failures of serious accidents that make the elevator unusable, but they can be left for a long time, for example, rubber of rollers supporting the door. An undesired abnormality such as anisotropic deformation of the outer ring made of it will not occur, and it will not cause any problems in using the elevator. It is a relatively minor abnormality such as poor landing that causes a step between the car floor and the building surface, and these abnormalities cannot be extracted. For this reason, it has not been possible to accurately grasp the cause of the accumulation of these slight anomalies and a serious accident, and the operation anomaly that occurs only during normal service of the elevator.

In addition, the relay contacts and the hall call and car call lamps incorporated in the control circuit may deteriorate in use and eventually malfunction or become unlightable. Although maintenance and replacement was carried out, the frequency of use of relays and lamps varied depending on their installation location.Therefore, some maintenance parts were replaced with new ones even though they had almost no deterioration due to use. Many parts were to be discarded in vain.

Therefore, by regularly checking the frequency of use of these maintenance parts during normal service, the running state of the elevator, and the presence or absence of abnormal operation, it is possible to perform accurate and waste-free maintenance during normal service. An enormous amount of memory is required to accumulate various measurement data of the elevator at any time, for example, at each regular inspection period, which is not very realistic in terms of installation cost.

An object of the present invention is to accurately grasp a relatively minor operation abnormality that cannot be grasped during maintenance operation performed during regular maintenance inspections to prevent a serious accident from occurring, and prevent unnecessary replacement of maintenance parts. An object is to provide an inexpensive elevator maintenance device that can be eliminated.

[Means for solving the problem]

In order to solve the above-mentioned problems, the data recording device records the operation state data collected from the elevator at any time during the normal service of the elevator, and the transmission device at the time of the regular notification operation for checking the communication device and the communication line. The response notification is made based on the regular notification command issued from the maintenance center, and the operating state data of the elevator stored in the data recording device is transmitted to the maintenance center.

[Action]

During normal service of the elevator, the operating state data collected by the elevator is sent to the data recording device, and the data recording device records the received operating state data of the elevator at any time. At the time of the regular report operation, the maintenance center issues a regular report command to inspect the communication device and communication line, the transmission device responds based on the received regular report command, and the operation of the elevator stored in the data recording device. Transmit status data to the maintenance center.

〔Example〕

 An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a system configuration diagram of an elevator maintenance device according to the present invention. The elevator is configured by a car 1 and a counterweight 2 suspended in a sheave 4 via a rope 3 in a slipping manner, and a shaft of the sheave 4 is connected to a broom 5, an electric motor 6 and a pulse generator via a speed reducer. Machine 7 is attached. The electric motor 6 is composed of a control device 8 and a disconnector 9 and is a main power source
The rotation direction and speed are controlled by the output of the power control device 11 that controls the power supplied by 10. Here, the control signal of the power control device 11 is an output of a signal from the microcomputer 12, and controls the traveling direction of the elevator and the brake 5. Further, the control device 8
Is configured to be controlled by the output of the speed control circuit 13 to which the output of the pulse generator 7 and the output of the microcomputer 12 are input. In addition, the microcomputer 12 inputs signals 14 from various safety devices installed in the elevator to output an elevator stop command or the like when a failure occurs, or is input via a tail cord connected to the car 1. Various kinds of car information and information from the pulse generator 7 are input and the elevator is controlled by them. In addition, the communication port 15 is connected to output various kinds of information to the outside.

The power control device 11, the micro computer 12,
The elevator control device 16 composed of the speed control circuit 13 and the communication port 15 includes a data recording device 17 for recording the operation state data collected from each part, and a data recording device 17 thereof.
An elevator maintenance device 19 including a transmission device 18 including a modem device for converting the operating state data from the device into a voice signal is connected. Further, the elevator maintenance device 19 includes a maintenance center 23 including a modem device 21 for converting a voice signal from the modem device in the transmission device 18 into an electric signal and an information processing device 22 for processing various information, Connected via path 24.

The data recording device 17 in the elevator maintenance device 19 is the second
As shown in the figure, the MPU171, which is configured as a micro computer and is a micro processing unit
A ROM 172 for storing a program, a RAM 173 for recording operating state data of the elevator, a communication port 170 connected to the communication port 15 of the elevator, and a communication port 174 for inputting / outputting signals to / from the transmission device 18, It is composed of a system bus 175 for transmitting addresses and control signals between these devices.

The processing steps of the elevator maintenance device 19 thus configured will be described with reference to the processing flow chart of FIG.

At the time of normal service, as shown in step S1, various operation state data are input from the elevator controller 16 to the communication port 170. This operation state data is, for example, various safety device information, information such as traveling direction and speed, and landing state information. Next, in step S2, only the operating state to be transmitted to the maintenance center is recorded in the RAM 173. At the time of normal service, the processing is repeated from step S1 to step S2 to accumulate the operation state data.

After a predetermined period has passed, the maintenance center 23
It is assumed that the scheduled notification operation occurs at 22. Then, the information processing device 22 calls the elevator maintenance device 19 via the communication path 24 and confirms that the communication line and the elevator maintenance device 19 are functioning normally. Upon receiving the regular report command, the MPU 171 of the elevator maintenance device 19 confirms that the regular report operation is performed in step S3 via step S1 and step S2 as in the normal service. Then, as shown in step S4, the operation status data stored in the RAM 173 is read and transmitted to the transmission device 18, and thus the modem device in the transmission device 18 converts the operation status data into a voice signal and transmits it via the communication path 24. Can be sent to the maintenance center 23. The above processing is executed by the MPU 171 according to the program stored in the ROM 173.

In this way, since the operating state data of the elevator accumulated during the normal service can be transmitted to the maintenance center 23 every time the regular reporting operation is performed, an undesired abnormality caused by being left for a long time and a slight abnormality are accumulated. Therefore, it is possible to accurately grasp the cause of a serious accident and the operation abnormality that occurs only during normal service of the elevator, and it is possible to accurately predict the use deterioration state of the maintenance parts. Moreover, RAM1
Since the operating state data accumulated in 73 is updated each time it is transmitted to the maintenance center 23, the storage capacity of the RAM 173 can be made as small as possible.

Further, the transmission of the operating state data of the elevator to the maintenance center 23 is performed together with the response notification performed based on the scheduled notification command issued from the information processing device 22 of the maintenance center 23, so that the maintenance center 23 can communicate via the communication path 24. When the elevator maintenance device 19 of a large number of elevators is communicatively connected, the elevator operating state data transmitted from the plurality of elevator maintenance devices 19 to the maintenance center 23 may interfere, or the information processing device 22 is processing. It is possible to prevent the occurrence of troubles such as operation being interrupted, and at the same time as confirming the normal operation of the communication line and the elevator maintenance device 19 at the time of the periodical notification operation that is performed, the transmission of the elevator operating status data is possible. Since it is performed, it is possible to reduce the call charge required for transmitting the operation state data once.

In the above-described embodiment, the elevator maintenance device 19 is configured by a microcomputer different from the microcomputer 12 in the elevator controller 16, but the microcomputer 12 may be provided with its function. ,
Even if the modem device in the transmission device 18 is omitted and the transmission device 18 is directly connected to the passage, the same effect can be obtained.

〔The invention's effect〕

As described above, according to the present invention, the data recording device records the operation state data collected from the elevator at any time during the normal service of the elevator, and the transmission device transmits the communication device and the communication line from the maintenance center at the time of the regular notification operation. In addition to sending a response based on the regular report command for inspection, the operating status data of the elevator accumulated in the data recording device is transmitted to the maintenance center. It is possible to accurately grasp minor operational abnormalities and prevent the occurrence of serious accidents, and it is possible to eliminate wasteful replacement of maintenance parts.
Furthermore, it is possible to provide an inexpensive elevator maintenance device that prevents interference with transmission of elevator operating state data from another elevator maintenance device and interruption of operation during processing at the maintenance center.
