Artificial detection of linear motors air gap has the problems of low detection efficiency and inaccurate detection data.In order to solve these problems,an on-line detection air gap system based on laser sensors is designed and developed.The hardware part of the on-line detection system consists of a control unit and an acquisition unit.The control unit includes a train number identification,a shaft position sensor and a PLC.The acquisition unit takes a laser displacement sensor as a core.Then,the software part of the system is designed,which is composed of data acquisition,data processing and Web publishing.Finally,the actual field operation test is carried out.The test results show that the system is accurate and stable,and it can meet the operational maintenance requirements.
