Description

Remote diagnostic device of elevator

The present invention relates to a technology for diagnosing an elevator from a remote location. In particular, when receiving an operation information, an abnormality, etc. from an elevator control device and reporting it to a local server installed in a local maintenance center through a telephone line or a dedicated line, The regional server is concerned with an elevator remote diagnosis device that takes corresponding action and reports the necessary matters to the integrated server of the central monitoring center via a dedicated communication network.

In particular, in order to manage the operation status, fault information, and life check of each elevator in a large area, the number of high-rise buildings in Hyundai has to be equipped with a lot of manpower, structural maintenance, and fault handling system. If this is inefficient or unreasonable, it will not only cause a lot of inconvenience to the people entering and leaving the building, but it can also pose a danger to the body. Therefore, more efficient management of such maintenance and troubleshooting system and management of detailed information and operation status of all elevators through the computer network will not only provide more efficient and quick response to failures, but also prevent potential hazards. You can be prepared more actively.

In general, in order to monitor the elevator remotely, a monitoring terminal for monitoring the function of the elevator controller is installed, and a remote monitoring center is provided with a monitoring diagnostic apparatus for collecting and diagnosing and processing information transmitted from the monitoring terminal. Connect to the telephone network.

The present invention relates to a structure and operation method of a remote diagnosis device having a structure that solves the disadvantages of the remote diagnosis device having such a configuration.

Conventionally, it comprises an elevator, an elevator control device, a monitoring terminal device connected to an elevator control device, and a remote monitoring host (diagnostic device) of a maintenance center for monitoring a plurality of elevators. If an abnormality occurs in the elevator control device, the detected abnormality is transmitted to the monitoring terminal device, and the monitoring terminal device receives information such as operation history, driving status, and abnormal state from the elevator control device and outputs it to the maintenance center. The maintenance center is configured to perform fault diagnosis processing with a diagnostic program that monitors and diagnoses elevators by receiving information collected from a monitoring terminal device.

1 is a view showing the overall configuration of the monitoring terminal device 105-108 monitoring the elevator control devices 112-125 in the prior art connected to the maintenance center 111 through the telephone network 109. The explanation is as follows.

The monitoring terminal device (105-108) is connected to the elevator control device (112-125) by a communication signal line and monitors them, and when abnormality is detected, the abnormality detection contents are transmitted to the maintenance center (111) through the telephone network (109). send.

The client computer in the maintenance center 111 analyzes the operation history, the driving state and the abnormal state data of the elevator control unit 112-125 sent from the monitoring terminal device 105-108 to diagnose failures such as the cause of the abnormal occurrence. Is done.

The elevator controllers 112-125 are based on information detected by various sensors, switches, etc., when driving status signals such as elevator trapping, starter system, safety system, power system, and door system are detected. The abnormalities are transmitted to the monitoring terminal device 105-108.

The monitoring terminal device 105-108 periodically monitors the driving state of the elevator control device 112-125, and the driving state signal is stored in the memory of the monitoring terminal device 105-108 as a driving history for each system. It is. These driving histories and driving states are transmitted to the maintenance center 111 and stored in the large-capacity database server system 101.

When the maintenance center 111 receives this information, the elevator control apparatus 112 is based on the previous driving history transmitted from the monitoring terminal device 105-108 and the current driving state in an abnormal state. -125), the remote diagnosis program based on the configuration, operation signal flow, and the experience of maintenance is started in the large-scale database circuit to analyze the cause of the failure and to receive the corresponding maintenance instruction.

As described above, in the conventional remote monitoring technology, when an error occurs in the elevator, the remote monitoring host (diagnostic device) of the maintenance center receives the operation information, operation history, and abnormality detection information from the elevator control device to identify the cause of the error. It needs to be received through. The amount of this information is quite large, so it takes a lot of transmission time. In addition, maintenance centers generally monitor a large number of elevators, so the sum of the time received from each elevator is a huge economic loss and complicated to maintain and manage. In addition to the fault information reported by the elevator to the maintenance center, communication must also be transmitted from the maintenance center to the elevator controller periodically requested, so the amount of communication burdened by the remote monitoring center becomes more and more. A failure occurred in the elevator control unit, but the cause of the diagnosis is not impossible to diagnose at a remote maintenance center, but the reliability of the diagnosis result is not practical. Therefore, from this point of view, it is efficient in the maintenance center to manage only the details of the failure and the cause of the failure for each elevator. Diagnosis device of remote monitoring center should report the failure from all elevators under management and collect and analyze the operation history. If the number of management in the area is continuously increasing or managing the big city and wide area, In spite of the expansion, the increase of the cost and the increase of the operation cost of the facility, the efficient operation is not possible as a whole, and this problem rather affects the operation of the overall remuneration system.

Therefore, the technical problem to be achieved by the present invention is to compensate for the irrationality caused by the conventional disadvantages, and to improve the efficiency of operating the diagnostic apparatus according to the increase in the number of elevator management. In addition, it is possible to improve the overall efficiency of the elevator remote diagnosis system while minimizing the failure response time by distributing the apparatus performing the diagnostic function locally and dividing the roles according to the regional characteristics.
