Research and application of embedded technology in remote network monitoring system of coal mine

摘要

Aiming at the weakness and deficiency of current coal mine monitoring system, this paper discusses the design and implementation of a platform to remotely monitor and control coal mine production processes over Industrial Ethernet by using the embedded technology. Integrated with each lower computer terminal are S3C2410 microprocessors that can be used for connectivity to the monitoring network effectively. Besides the terminal core S3C2410, the hardware circuits of memory module, Ethernet module, USB module, input and output channels, LCD display module, and RS232 serial module are studied and designed. Additionally, Linux-based application software that facilitates remote monitoring and control of lower computer terminals using Qt/embedded has also been developed. The monitoring system presented in this paper can not only meet the requirements of coal mine production process, but also has a wide range of applications in other industrial monitoring fields.
