现阶段煤矿使用的变频调速控制系统几乎都应用了PLC技术,因为这种技术可以提到该系统的安全可靠性,同时因其编程比较简单,操作起来十分方便,不必对技术人员进行专门的培训,另外,其还具有安全制动的功能,一旦系统发生故障,可以进行紧急制动。主要通过PLC变频控制功能及其系统介绍,进而探讨了PLC技术在煤矿提升机变频控制系统中的实践应用,希望能够对PLC技术更好的应用提供帮助。
At this stage almost all the coal mine frequency control system used PLC technology, because this technology can be referred to the safety and reliability of the system, at the same time because of its programming is relatively simple, very easy to operate, do not have to technical staff specialized Training, in addition, it also has a safety brake function, in the event of system failure, emergency braking. Mainly through the PLC frequency conversion control function and its system introduction, and then explores the PLC technology in the coal mine frequency conversion frequency conversion control system practical application, hoping to be able to the PLC technology the better application help.
