Abstract:Aiming at the low accuracy and low monitoring effect of traditional monitoring system, a spacecraft attitude monitoring system based on Internet of things is proposed. According to the monitoring system structure, real-time monitoring of the host computer, control aircraft attitude, build the database to store and record the parameters, the design of hardware; build dialog interface and the corresponding analysis program function, improve the system software program flow monitoring function, according to space flight attitude data change display, analyze the data communication module, control module, and add the emWin transplant interface, complete the design of the spacecraft attitude detection system based on Internet of things. The experimental results show that the system has a short monitoring time and high precision, which greatly improves the monitoring effect of the system.
