The SCADA Monitoring and Control System Based on CAN Bus in Coal Mine

摘要

This paper puts forward a mine automatic integral consolidated network based on Control Area Network bus technology. This network features a simple construction and connection, a high reliable real-time data communication, unrestrained node setting, an optional communication medium and multi-host-node bus construction, with which it will compose a Supervisory Control and Data Acquisition (SCADA) network consisting of production, transportation, environment monitoring and other production links, and the integral monitoring will be realized on the ground of mine so as to reach a no-man-on-watch at some nodes, which effectively solve the shortcoming of "isolated island of information" among production links in nowadays coal mine.
