从煤矿矿井的主通风机不通风倒机控制系统来看,它的工控机如果使用时间过久就会造成死机,因而应该在交换机上连接传感器,运用不同的工控机共同读取数据。针对温度巡检仪、电参数采集模块所输出的RS485信号不能在交换机上进行直接接入的情况,提出相关的改进方案,并根据其优缺点,择优选择增加PLC的RS485模块方案。采用这样方案可以让系统更好地运行,预期效果较佳。
From the coal mine main ventilator non-ventilated down control system point of view, it’s IPC if used for too long will cause crashes, and therefore should be connected to the switch sensor, the use of different IPC read the data together. For the temperature inspection device, the RS485 signal output by the electrical parameter acquisition module can not be directly accessed on the switch, and the related improvement solutions are proposed. Based on the advantages and disadvantages, the RS485 module solution of the PLC is selected optimally. Using such a program can make the system run better, the expected effect is better.
