副井提升系统安全回路及上位机优化改造

Optimal reform of safety circuit and upper computer in auxiliary shaft hoisting system

针对煤矿副井提升系统安全回路软硬件及上位机中存在的不足进行了优化改造,改进了过卷试验方式,将闸系统紧停信号引入安全回路,并将安全回路各节点状态信号引入RSView32人机界面,实时显示安全回路状态;根据现场检修需要,在上位机增加了复位显示功能及行程偏差大报警信号。实际应用表明,该优化改造可迅速定位故障节点,实现软硬件互查。

In view of shortages in hardware and software of safety circuit and upper computer ot coal mine auxiliary shaft hoisting system, optimal reform was applied to the system. Experiment method of over wind was improved, signal of brake system emergency stop was introduced to the safety circuit, and state signals of each node of the safety circuit were introduced into RSView32 human machine interface, so as to display state of the safety circuit in real time. According to requirement of site maintenance, function of reset display and alarm signal of big stroke deviation were added to the upper computer. The actual application shows that the optimal reform can locate fault node rapidly and realize inter-checking between the hardware and software.
