基于DSP和单片机的煤与瓦斯突出监测系统设计

摘要

In order to solve problems of special construction, complex operation and poor reliability of normal contact forecasting method of coal and gas outburst at present, the paper put forward a design scheme of monitoring system of coal and gas outburst based on DSP and single-chip microcomputer according to basic principle that coal and gas outburst would accompany electromagnetic emission signal,and gave structure, function and realizing methods of software and hardware of the system. The system adopts dual-CPU working mode of TMS320C5409 DSP and AT89S5 single-chip microcomputer, namely TMS320C5409 completes tasks of data collection and procession and AT89S5 does tasks of coordination of the whole system and man-machine interaction, which greatly improves operating efficiency and realizes real-time and non-contact prediction of coal and gas outburst.%针对目前常用的接触式煤与瓦斯突出预报方式需要专门施工作业且操作复杂、可靠性差等问题,根据煤与瓦斯突出伴随产生电磁辐射信号的基本原理,提出了一种基于DSP和单片机的煤与瓦斯突出监测系统的设计方案,给出了该系统的结构、功能及软硬件实现方法.该系统采用TMS320C5409 DSP和AT89S5单片机的双CPU工作模式,分别完成数据采集和处理任务、整个系统的协和人机交互任务,大大提高了系统运行效率,实现了实时、非接触式的煤与瓦斯突出预测.
