Abstract:In order to solve the problem of quantity insufficiency, the group is difficult and the comprehensive cost higher, building a set of self-propelled gun fire control system virtual training and testing system based on "ARM + WinCE". designing integrates signal acquisition and processing, computing, control, and other functions in one of the basic circuit of fire control system based on ARM; Design hardware and software of fault diagnosis based on the WinCE, DSP, XML, bring up the operation system, the theory and operation evaluation, fault diagnosis, etc. Practice proves that the simulation training system is stable and reliable operation, greatly improved the benefit of the equipment training.
