摘要
针对英格索兰压风机自带远程控制硬接点少,难以实现压风机多参数在线监控的问题,提出一种基于Modbus通信方式的煤矿压风机集控系统结构及功能,重点介绍了该系统中西门子S7-300PLC通过Modbus方式与英格索兰压风机通信的实现方法。该通信方法硬件配置简单,程序条理清晰,能实时采集大量压风机工作参数,无需另配检测传感器。运行结果表明,基于该通信方法的煤矿压风机集控系统运行良好,可靠性高。
For problem that it is difficult to online monitor multi parameters of Ingersoll Rand air compressor because the air compressor has few hard contacts, the paper proposed structure and functions of a centralized control system of mine-used air compressor based on Modbus communication mode, and focused on realization of Modbus communication method between Siemens S7-300 PLC and the air compressor. The communication method is simple in hard configuration as well as clear in programming, and can real-timely collect a lot of working parameters of the air compressor without any other sensors. The operation result showed that the system runs normally with high reliability.
