Design and Implementation of Online Inspection System for Linear Motor Air Gap

In order to solve the problems of low detection efficiency and inaccurate detection data in the manual detection of the air gap of linear motor, an online air gap detection system based on a laser sensor is designed and developed. First of all, the hardware part of the online detection system is designed, and the control units including vehicle number recognition, axial position sensor, and PLC are described in detail, as well as the acquisition unit composed of laser displacement sensor, and then the software of the system is designed. Including data acquisition, data processing unit and web release, finally, the actual field operation test is carried out, the test results verify the accuracy and stability of the system and can meet the needs of operation and maintenance.
