摘要
针对煤矿井下电气设备要求本质安全的特点,设计了一种矿用隔爆兼本安型计算机信号隔离器,主要介绍了该隔离器的硬件电路设计。该隔离器主要用于矿井中本质安全型计算机主机与外部输入输出设备的连接,能够实时地传送键盘输入的数据,具有良好的信号隔离功能和抗干扰性能。
According to characteristics of intrinsic safety electrical equipments used in coal mine,a signal isolator for explosion-proof and intrinsic safety computer used in coal mine was designed,design of hardware circuit of the isolator was mainly introduced in this paper.The isolator is used to connect main computer of intrinsic safety computer with external input/output devices,which can real-timely transmit input data with keyboard and has good function of signal isolation and anti-interference performance.
