This paper completes the design and development of supervisory control system. First, the system design scheme is determined on the base of upper and lower computer after the analysis of structure and function of test- bed and MT312-2000 experiment standard. The selection of hardware is carried out and the control loop is designed according to the requirements of safety, real-time and reliability. The upper computer software with good man-machine interface is developed using VB6.0. The test process information system is built, which is convenient for the management of test data and the printing of report. The software of lower computer is exploited using STEP7 which can control test process automatically. The communication is realized by using MSComm in VB based on the free port mode This system has been used in the biggest hydraulic support test-bed in China which runs stably and accurately, reduces cost and improves test efficiency.
