Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an abnormality monitoring system for a pump station, and more particularly, to a system for remotely monitoring occurrence of an abnormality such as a pump failure, an abnormally high water level, or a power failure at pump stations scattered at a plurality of locations.
[0002]
[Prior art and its problems]
Conventionally, in the pump station abnormality monitoring system, as shown in FIG. 2, a unique report setting information table is set in the reporting device for each scattered pump station, and the report information is a unique failure occurrence information table number. Since it is reported as ciphertext data of (event number), the central monitoring device installed at the monitoring site on the receiving side can decrypt the ciphertext data similar to the pump station in advance so that the ciphertext data can be decrypted. It is necessary to set decryption data.
[0003]
As described above, in the conventional system in which the same information table as the notification setting information table for each pump station must be set in the central monitoring device, the number of monitoring pump stations is limited by the storage capacity of the central monitoring device. . In order to increase the pump station capacity beyond a certain number, it is necessary to increase the storage capacity of the central monitoring device or shift to a monitoring system from a plurality of locations by newly adding a central monitoring device.
[0004]
In addition, if both pump stations and the central monitoring device do not have the same information table, they cannot function normally, and the settings of the information table data held by each pump station will change as the environment changes. In such a case, it is necessary to change the setting of the decryption data for the pump station in the central monitoring device each time.
[0005]
And the process at the time of abnormality occurrence in a pump station is performed in the procedure as shown in FIG. 5, and the return is processed in the procedure as shown in FIG.
[0006]
OBJECT OF THE INVENTION
The object of the present invention relates to monitoring of pump station abnormalities, and it is not necessary to set the same ciphertext data as the pump station in advance in the central monitoring device, and the number of pumping stations is increased even if the central monitoring device has a small storage capacity. The central monitoring device can respond appropriately to anomaly reports from a large number of pump stations without any restrictions, and even if the information table data of each pump station is changed, the central monitoring device Is to provide a low-cost and high-efficiency system that can respond immediately without requiring changes to the decryption data settings as a countermeasure.

【Example】
Examples of the present invention will be described below.
[0009]
As shown in FIG. 1, the central monitoring apparatus (hereinafter referred to as “master station”) has only an information table structure, and does not hold information table data, but is left blank. And when the master station reports from each pump station reporting device (hereinafter referred to as “slave station”), for example, the event number (information table number) corresponding to the abnormal content such as No. 1 pump failure, abnormal high water level or power failure, etc. Receive and register ciphertext data as anomaly information, then request the slave station for the unique information table data held by the slave station, and for decryption sent from the slave station in response to the request The information table data is registered, and the corresponding abnormality content is displayed based on the registered data. That is, the master station receives both the ciphertext data (event number) and the decryption data (information table data) from the slave station and displays the corresponding abnormality content. In addition, when there is a report from the next slave station, the master station automatically uses the same information table data as the previously registered slave station to the unique information table data held by the next slave station. And new information table data will be held. The master station can always cope with one information table, and both the master station side and the slave station side can have the same information table data.
[0010]
The processing procedure when a failure occurs will be described below with reference to FIG. (1) Failure occurrence ··· A failure in the pump station is detected by the slave station installed at the pump station. (2) Telephone line capture → line connection The failure information is reported from the above slave station to the master station installed at the monitoring location using the telephone line. (3) Failure occurrence information reception / registration The master station receives and registers the slave station ID, failure occurrence time and occurrence failure event number (information table number) transmitted from the slave station. (4) Request for failure display information: Requests communication of the report setting information table data held by the slave station to the slave station. (5) Failure display information reception / registration ... The slave station transmits the contents of its own report setting information table data to the master station in response to the communication request of the master station, and the master station receives this and sets the report. Register in the information table. (6) Line disconnection The master station disconnects the telephone line after receiving and registering the above fault display information. (7) Verification of failure occurrence information and failure display data The master station compares the event number (information table number) of the failure occurrence on the slave station side already registered with the report setting information table data to generate the failure. The event name and pump station name corresponding to the event number are additionally registered in the failure occurrence information. (8) Failure display ... The failure information of the pump station registered earlier is displayed on the display device. ▲ 9 ▼ END
