Abstract:

Aiming at the problems of difficulty and low efficiency of ground test caused by large power supply and distribution topology and complex electrical coupling of active launch vehicle measurement system, a modular test system for power supply and distribution of launch vehicle measurement system is proposed. Firstly, the system is decoupled into power supply, signal acquisition, data processing and communication modules through standardized interface, and a modular test platform for power supply and distribution test of measurement system is constructed. Secondly, based on the methods of isolation amplification control, multi-channel acquisition, high-precision data verification and power redundancy compensation, the power supply and distribution control circuit and analog sampling circuit are designed to complete the power supply and distribution control and state monitoring of the measurement system. Finally, based on the Windows presentation basic framework, the C language is used to develop the power supply and distribution control software of the host computer measurement system, which realizes the independent test and integrated test of the launch vehicle measurement system module, and improves the reliability of the launch vehicle measurement power supply and distribution system. The functional verification test of the power supply and distribution module test system is carried out in an aerospace electronic laboratory in Shanghai. The test results show that the system is effective and reliable. The standardized interface design and scalability provide a new idea for the test of complex aerospace systems and have important engineering application value.
