Application and Research of MODBUS Protocol in Speed Sensor Detection Device for Urban Rail Vehicles
Simulate different vehicle speeds using three-phase asynchronous motors to test the performance of the speed sensor detection device for urban rail vehicles.To overcome the inconvenience and danger caused by direct control of the frequency converter on site,Siemens V20 frequency converter based on MODBUS protocol is used to communicate with the industrial computer and achieve remote control.After verification,the communication of the frequency converter is smooth and stable,which can meet the requirements of on-site testing.
