为了提高电牵引采煤机变频牵引单元工作的可靠性和稳定性,引进PROFIBUS总线技术,设计了采煤机变频牵引单元参数化监控系统,解决了PLC控制系统和变频牵引单元的数据通讯问题。试验结果表明,该控制系统稳定、可靠、操作简便,满足了工艺要求;同时将参数上传至上位机,还可实现采煤机变频牵引单元的远程监测和控制。
In order to improve the reliability and stability of the work of frequency conversion traction unit of electric haulage shearer, the PROFIBUS bus technology was introduced to design the parametric monitoring system of shearer frequency conversion haulage unit, which solves the problem of data communication between PLC control system and variable frequency haulage unit. The test results show that the control system is stable, reliable and easy to operate, which meets the technical requirements. At the same time, the parameters are uploaded to the host computer, and the remote monitoring and control of shearer variable frequency traction unit can also be realized.
