Aiming at the requirement of pre -launch simulation test of CZ-6 Power Control and Testing system,A simulation test plat-form is designed according to the characteristics of exhort -period rapid launch and shelter operation. The test platform uses the electrical sig-nal that simulate the power distribution valve, pressure sensor and connector hardware interface signal to form the hardwusing of software simulation of the working principle of the gas distribution platform,ro cket＇s connectors, and the base filling communica-tion to form the software model layer. The hardware interface layer and the software model layer are conncected by the RS422 busand the PC104 bus to realize modularization and combined type. The test platform composes a closed -loop test environment with CZ -6 power con-trol and testing system. The pratice shows that all work status of CZ -6 Power Control and Testing system are met and the test efficientcyis improved.
