摘要
为实现煤矿多种场合使用设备的硬件统一,使之适应灵活的通讯方式,在信号装置上采用了西门子S7-200可编程控制器的PPI通讯方式,自由口通讯方式和总线式音频通讯方式。该通讯方式的运用,提高了煤矿自动化水平。
In order to realize the hardware unification of mine equipment in various occasions, which adapt the communication ways flexible. The PPI communication way of Siemens S7-200 PLC, free interference communication ways and fieldbus audio communication way are adopted on the signal devices. These new communication ways improve the automation level of coal mine.
