[0004] 对煤矿井下的多级带式输送， 其有多个触摸屏和多个 CAN板， 由于作为中转站 的触摸屏其主要功能是显示， 处理众多数据能力有限， 从而造成数据传输的速 度会很慢， 甚至死机； 同样， PLC传输的指令和数据到各个触摸屏上， 也需要经 过作中转站的触摸屏， 速度也会很慢或死机。 严重影响到集控装置的实吋性和 可靠性， 造成设备无法使用。 当作为中转站的触摸屏出现故障吋， 整个装置将 无法使用。 再有， 由于经过了作为中转站的触摸屏， 其传输距离相应的增加， 对远距离的监控和数据传输， 将使数据传输的信号衰减， 增加干扰， 从而影响 数据传输的正确率， 上述连接方法难以能够满足煤矿安全生产的需要。 煤矿井 下的多级带式输送监控另有一些不够周全、 合理的地方， 需要改进。 如何解决 煤矿井下有多个触摸屏和多个 CAN板的多级带式输送的监控， 是煤矿井下多级 带式运输亟待解决的问题。
[0005] 为解决上述问题， 本发明将解决煤矿井下有多个触摸屏和多个 CAN板的远距离 多级带式输送的监控和一些不够周全、 合理的地方， 充分发挥 PLC的特点， 实现 煤矿安全生产的目的。
