Method for identifying and judging safety of indication state of switch machine

The invention relates to a method for identifying and judging the safety of the indication state of a point switch, which can identify the state of the point switch according to the speed of a driving part and the displacement of an electric contact control part and a stretching state part, is irrelevant to electric operation or hand operation, and has the advantages of wide application range, accurate judgment result, simple judgment method and high reliability. The state of the switch machine can be judged, a monitoring program can be efficiently executed, whether the representation state of the switch machine after electric locking is matched with the actual mechanical locking state and position or not can be recognized, then wrong representation is recognized, the safety of the switch machine is improved, and the danger of heavy loss of personnel and property is prevented. 本发明涉及一种转辙机表示状态安全性的识别判定方法，它根据驱动零件的速度、电气接点控制零件及拉伸状态零件的位移可以辨别转辙机所处的状态，并且与电动操作还是手摇操作无关，适应范围广，判断结果准确，判断方法简单，不但可以判断转辙机状态，用来高效执行监测程序，还可以识别电气锁
