The invention provides a state detection method and device for an electric turnout switch machine system, equipment and a medium. The method comprises the steps: the detection equipment obtains motor current and expression rod / action rod displacement of the electric turnout switch machine system to be detected at all set moments; health state characteristic data of the to-be-detected electric turnout switch machine system is obtained according to the displacement of the indication rod / action rod and the motor current; according to the health state characteristic data of the electric turnout switch machine system, the motor current and the displacement of the indication rod / action rod, operation state data of the electric turnout switch machine system to be detected is obtained; and the state of the electric turnout switch machine system is determined according to the running state data and the health state characteristic data of the electric turnout switch machine system. The operation state data comprises a turnout physical position, a turnout gap, a conversion force, a conversion resistance and a turnout close attachment force. According to the method, the detection coverage can be effectively increased, and the precision and accuracy of state detection are improved.
Description
technical field [0001] The present application relates to the technical field of detection, and in particular to a state detection method, device, equipment and medium of an electric switch machine system. Background technique [0002] The electric turnout switch machine system is an important device used to switch the turnout, lock the switch point rail, and indicate the position of the turnout, and has been widely used in the field of rail transit. If the electric turnout switch machine system fails during operation, it will affect the safe production and operation of rail transit. Therefore, it is very necessary to monitor the operating status of the electric switch machine system. [0003] At present, the monitoring of the operating state of the electric switch machine system mainly obtains the vibration signal of the switch machine and the internal temperature of the switch machine through vibration sensors, temperature sensors, voltage sensors, current sensors, displa...
