An angle retainer training simulator of some rocket launcher is designed based on ARM to reduce equipment depreciation, and to display operating principle and common fault. The TX2440A development board is adopted to design simulators of altitude and direction angle retainer, as well as an I/O control and display circuit. Moreover, the Linux C++ multithread programming technology and the QT technology are utilized to develop hardware driver, driver caller, and operation interface. Consequently, operating principle and common fault simulation of both angle retainers are realized. Experiments show that both the work state and the fault phenomenon of those angle retainers can be revealed precisely in real time, providing a reliable platform for teaching and training.
