摘要
利用整块式继电器作为主要控制部件代替PLC实现矿井装载操作系统的闭锁及联锁功能,改造后系统的成本较低,线路简单,闭锁关系严密,实用性强,故障率低,且达到了井下防爆要求,能真正满足生产实际的需要,对其他矿井同类操作系统也有较大的推广应用价值。
Used the block - control relay as the main components to take the place of PLC to achieve the closed and interlocking functions of loading operating system, that will be lower - cost, simple lines, blocking fight relations, practical, low failure rate and achieve a mine explosion- proof requirements, and meet the actual needs of production, it also have greater promotion value to other operating systems of the similar mine after renovated.
