在煤矿调度系统中，传统的模拟盘驱动常常采用硬件直接与煤矿监测系统相连，也有的是利用地址锁存器和数据锁存器等构成的硬件电路来实现与主机的连接。然而．现有连接，不管是那种，由于都是采用硬件相连（虽然存在实现简单的优点），却不可避免地存在如下的缺点。（1）．由于
In the coal mine dispatching system, the traditional analog disk drive often uses the hardware directly connected with the coal mine monitoring system, and some uses the hardware circuit formed by address latch and data latch to realize the connection with the host computer. however. The existing connections, no matter the kind, are all connected by hardware (although there are advantages for achieving simplicity), but inevitably the following disadvantages exist. (1). due to
