Abstract:
The main objective of this work is the development of an instrument system for the evaluation and diagnosis of the launch system. Furthermore, the system can be used to launch the rocket instead of failed launch system as needed. The system could overcome the difficulty of fault testing and troubleshooting in application and maintenance of a type of rocket mine-launching vehicle, the operating principle and fault characteristics of launch system, as well as failure parameters and fault distribution are addressed in detail. Consequently, the fault testing device based on embedded equipment is provided. It is composed of hardware platform and application software. The hardware, which is responsible for the acquisition of operating parameters for launch control system, consists of embedded micro-controller STM32F103, keyboard and highlight LED I/O, LCD, memory circuit, connector-adapter and dedicated connection cables. The application software is developed based on principle of state machine as well as expert system. The software operates in two modes of simplified and expert mode. In simple working mode, launch control system fault testing and substitution are accomplished. Otherwise, in expert mode, all the function of system testing, system substitution, fault-clear wizard and parameter management are completed. The fault testing device brings new ideas on the evaluation and diagnosis of the launch system.

Keywords: launch control system, fault testing, embedded technology, state machine, fault-clear wizard.
