摘　　要：TBM由PLC系统集中控制,对液压系统的温度、液位、压力、转速及机械机构的动作进行检测,使之按照设定的程序运行,从而完成各种工作状态。对PLC控制系统各种干扰因素进行分析,并在抗干扰设计中采取多种抗干扰措施,从而有效地抑制干扰,使PLC控制系统正常工作。TBM controlled by the PLC system, the hydraulic system, temperature, liquid level, pressure, speed and mechanical body movement detection, so that in accordance with the procedures set up to run, thus completing the various working condition. Analyzed PLC control system for all sorts of interference factors, and anti-jamming design to take a variety of anti-interference measures, to effectively suppress interference, so that PLC control system work properly.
