As an important test equipment for the supporting unit of the missile weapon system, the localization research and development of the in-line power supply tester is of great significance to improve national defense security and independent and controllable technology. In view of the problems of the current tester relying on imported software and hardware, insufficient real-time performance, and low test accuracy, a localized solution based on the domestic Linux system and Qt framework is proposed. Through the multi-threaded scheduling algorithm and dynamic resource allocation strategy, the performance bottleneck of high-concurrency data acquisition and real-time processing is solved, the system response delay is < 10ms, and the test efficiency is increased by 20%. Combined with the dynamic calibration technology of timing parameters, the measurement error ≤± 0.1V, and the standard deviation is reduced from 0.8ms to 0.15ms, so as to achieve high-precision measurement of timing parameters. It satisfies the military"s demand for independent and controllable missile weapons test equipment, and provides a theoretical and technical reference for the design of localized test equipment.
