At present, the machining and assembly operations of spacecraft rely on manual operation, which affects the assembly accuracy of the structure inside the sealed cabin of the spacecraft. To this end, an assembly precision detection system for the spacecraft sealed cabin structure was designed to provide a basis for high-precision assembly of the spacecraft sealed cabin structure. Due to the complicated structure of the spacecraft's sealed cabin, in order to ensure that the detection system can maintain a stable and reliable working mode when using battery power, the system should issue an early warning message on the premise of sufficient battery power, so that the staff can take corresponding solutions in time. In the battery-powered circuit, the monitoring form of the undervoltage circuit is designed. The circuit is mainly composed of voltage comparators LM393 and 555 and a resonant circuit. When the battery power supply is insufficient, the micro-current high-efficiency 650nm resonant cavity LED in the resonant circuit will flash a warning signal. The STC89C52RC-40I-PDIP40 single-chip microcomputer central control unit is used as the core chip to test the sealing performance of the spacecraft sealed cabin. According to the principle of machine vision detection, a nonlinear filtering algorithm is used to enhance the image, to avoid the influence of external noise on the image acquisition result, and to filter out some white spots on the image. The testing process can be designed to obtain the test results of the installation accuracy of the instrument board and the installation and adjustment of the equipment mounting bracket. It can be seen from the experimental results that the highest detection accuracy of the system is consistent with the measured values, which provides equipment support for the optimization of the structure of the spacecraft sealed cabin.
