Abstract: In order to improve performances of control system of hydraulic support test-bed, the paper proposed a design scheme of computer control system of lifting platform of hydraulic support test-bed. It detailedly introduced design of hardware and software of each subsystem of the system, namely control subsystem of hydraulic pump station, 4-cylinder synchronization control subsystem of lifting platform and bolt control subsystem, and gave human-computer interaction interface of the system. The actual application showed that the system can finish computer control of lifting platform of hydraulic support test-bed magnificently.
