Description

  The present invention relates to a remote monitoring control system for monitoring measured value data of various facilities of water treatment facilities scattered in various places through a public line by a remote management center.

  In general, various facilities of water treatment facilities such as distribution reservoirs, simple waterworks, manhole pump stations, and drainage pump stations are intensively monitored by a remote management center. In a conventional remote monitoring and control system, measurement data of various facilities (pumps, valves, gates, sensors, etc.) is acquired by a data communication device, and an alarm is sent to the management center via a public line when abnormal data occurs. Was. In response to the alarm notification, the management center dispatched maintenance personnel to the site, grasping the state of the equipment concerned, investigating the cause of abnormal data, and taking recovery measures.

  As a prior example of a monitoring system using a public line, in Patent Document 1, in the case of abnormal content with a high degree of urgency, an automatic notification is immediately sent to the monitoring center via the communication line, and in the case of abnormal content with a low degree of urgency, There has been proposed a monitoring device that stores abnormality contents in the occurrence history storage means and notifies the monitoring center of the abnormality contents recorded in the abnormality occurrence history storage means at a preset time. In this example, since the maintenance staff only needs to be dispatched to the site only in the case of an abnormal content with a high degree of urgency, the dispatch to the site can be performed rationally.
