Research of remote network monitoring system of coal mine tunnel water

Abstract

In order to solve problems of existing monitoring system of coal mine tunnel water, for example, inflexible network expansion and inconvenient data acquisition, a remote network monitoring system of coal mine tunnel water was designed which was based on network publishing technology. Firstly, data acquisition circuit is designed as well as hardware circuit of monitoring substation. Secondly, RS485 bus communication between substation and main station is designed as well as communication between PLC Ethernet module and configuration software, so as to control RS485 bus data via industrial Ethernet. Lastly, configuration software driving GSM DTU module and Web publishing of configuration project are designed to implement remote network query and control of underground water. The application shows that the system is flexible in network expansion and convenient in data acquisition.
