Design of remote wireless monitoring system for coal mine main ventilator

Abstract

The main ventilator room of coal mine is remote and difficultly covered by wired network, so as to cause main ventilator monitoring system falling into information island. For above problem, a design scheme of remote wireless monitoring system for coal mine main ventilator based on mobile platform was put forward. The system uses a GPRS DTU to communicate with PLC for collecting field monitoring data, and the data is uploaded to a cloud data sever through GPRS network. On the other hand, mobile client based on Android system accesses the cloud data sever by use of socket communication mode through 3G, 4G or WiFi wireless network, so that users can remotely monitor operation status of coal mine main ventilator anytime and anywhere. The test results verify feasibility of the system.
