摘要
通过PLC主机完成整个选煤线的顺序控制、闭环控制、状态监测、显示、无线通讯系统和下位机控制系统组成,实现选煤厂生产过程控制,管线敷设量很大程度的减少,减少了电气安装工作量,费用大大降低。解决了通讯线缆布线复杂、电缆损坏率高的技术难题,实现集中控制系统数据无线通讯和自动化水平的提高以及无线网络的覆盖,能够推动选煤行业网络化和自动化技术的进一步发展。
It completes the sequence control, closed-loop control, condition monitoring, display, wireless communication system and lower-level machine control system of the whole coal preparation line through PLC mainframe to realize the production process control of coal preparation plant. The amount of pipeline laying is greatly reduced, the electrical installation workload is reduced, and the cost is greatly reduced. The utility model solves the technical problem that the communication cable has complicated wiring and high cable damage rate, realizes the improvement of the wireless communication and automation level of the centralized control system and the coverage of the wireless network, and can promote the further development of the network and automation technology of the coal preparation industry.
