Abstract: Equalizing test for rolling stock requires 8 sets of hydraulic oil cylinder which are controlled independently to drive the lift structure, needs to collect and store lifting height and wheel load data, calculate reduction rate of wheel load, and automatically stop when the rolling stock is elevated to a certain height. In this paper , according to the test need, a set of Measurement and Control System was developed, the upper computer was PC, the lower machine was S7-200 PLC, in the LabVIEW programming environment, the VISA interface function was called to establish the communication with the PC and PLC by PPI protocol, the data of displacement sensor and weighing sensor were collected and processed to control the hydraulic oil cylinder. The implemented Measurement and Control System of equalizing test for rolling stock could meet the needs of measurement and control.
