Abstract
Aimed at the current status and existing problems of safety monitoring of domestic coal mines, a computer-controlled coal mine safety monitoring system is proposed. The integrated system is composed of three subsystems: monitoring, communication and control subsystems. Monitoring subsystem is composed of gas, wind speed, negative pressure, temperature etc sensors, which are distributed in the mine and used to carry out real-time monitoring. The communication subsystem consists of Coordinators, Routers and End node and performs wireless communication. These two subsystems establish contact with the central control computer located on the surface by the CAN buses. The system can simultaneously transmit real-time data to the host computer in the management center and the mobile-phones of the responsible personnel by GPRS module, and when the data exceed the limited values, an alarm will occur. Compared with data transmission through conventional bus, application of wireless sensor network and GPRS network technologies reduces investment on underground lines-laying and maintenance difficulties, ensures timely, accurate and rapid transmission of data in all key underground mining zones and improves efficiency of the system. The system has such dominants as easy-building up, powerful-function, high-reliability, good-extendibility and etc. The system is an advanced approach to solve the present key problem that wireless communication distance is limited in the mine and has great benefits for coal mine safety production.
