在研究传统监控分站的基础上,提出监控分站的无线接入方案,通过无线传输网络实现时时监控,解决了现有的的监控系统的问题。针对国内煤矿监控系统存在监测盲点,研究便携式仪表无线接入技术,把便携式仪表作为固定式传感器的有效补充,解决便携式仪表的监测数据不能及时上传的难题,为实现矿井全面实时监控和有效预警提供技术保障,监控分站既有传统分站功能又能采集无线便携式仪表信号,监控分站到中心站采用CAN总线的数据传输方式。 Based on the research of traditional monitoring sub-station, this paper proposes to monitor the sub-station’s wireless access scheme and realize the monitoring from time to time through the wireless transmission network, which solves the problems of the existing monitoring system. In view of the existence of monitoring blind spots in the domestic coal mine monitoring and control system, the research of portable instrument wireless access technology, the portable instrument as an effective supplement to fixed sensors to solve the problem of portable instrument monitoring data can not be uploaded in time for the realization of a comprehensive mine real-time monitoring and effective early warning provide Technical support and monitoring sub-station Both the traditional sub-station functions and can collect wireless portable instrumentation signals to monitor the substation to the central station using CAN bus data transmission.
