Monitoring apparatus

Abstract

A monitoring apparatus that captures data in a router into a monitoring apparatus to cope with a communication abnormality in a monitoring system that uses the router, a modem, and a network. The monitoring apparatus comprises input modules 343, 345 for being input with a signal from a monitored object 303; a CPU module 341 for processing the signal from the input modules 343, 345; a communication module 342; a data bus 352; and a power module 340. The communication module has two connectors 204, 206 or more each connected to the network; a connection terminal connected to a power supply buss 351; a connection terminal connected to the data bus 352; a memory; and a CPU.

Description

technical field [0001] The present invention relates to a monitoring device, and more particularly relates to a technology for monitoring water supply and distribution facilities of sewers and sewers, industrial production equipment and sales data collection equipment. Background technique [0002] In the monitoring system of the prior art, a monitoring device is installed in a central monitoring room, and a monitoring device that transmits data on the field side to the central monitoring room is installed on the field side where equipment to be monitored is installed. A dedicated line or cable TV line is connected to form a monitoring system. In these communications, a router or a modem is connected to the monitoring device, and communication is performed between the monitoring devices at both ends of the communication line (for example, refer to Japanese Patent Application Laid-Open No. 10-327259). [0003] In the related art monitoring system, data on whether the communi...

AI Technical Summary

Problems solved by technology

However, since the router is outside the monitoring device, it is difficult for the monitoring device to obtain the data of the router.

In such a monitoring system, when a communication abnormality occurs, it is difficult to automatically determine whether there is a problem in any of the router and the modem, and it is difficult to perform an automatic recovery operation when a communication abnormality occurs

[0004] In addition, in the monitoring system of the prior art, since the site side and the central monitoring side are required to monitor the status of the site in the case of normal communication, abnormal communication will become an obstacle to the operation of the monitoring system.
