This article presents a method for testing and identification of a recovery material of certain missile, systematically analyzes the diagnostic approach and technology of PCB faults, expounds in detail design concept of the system, sets forth the solution using C8051F020 chip as microprocessor and testing of analog and digital I/O with built-in converter, contrives polarity discrimination circuit, provides software design process and main program by means of design thinking of modularized software, which help increasing program reliability and lowering development cost. The experimentation proves that this system is able to precisely position the faulty module of PCB to be identified, as well as make correct and reasonable opinion for maintenance. The design method and concept of this article is of significant value for reference in the research and development of similar testing and identification system.

In order to link missile of actuating mechanism to CAN bus, an interface between actuating mechanism and CAN bus has been designed. It provides a method for the designing and realization of the hardware and software of interface. This interface has been used in reality. It proves that this design is feasible.

The traditional LPT-based image mosaic algorithm has such problems as huge calculation load and narrow applied fields, etc. In view of that, this paper puts forward a mosaic algorithm based on SUSAN Corner Detection Algorithm and LPT, which will firstly make corner detection, and then, with the corner as the coordinate transform central point, choose proper search strategy to further reduce the calculation load. The result of experimentation shows that this algorithm is effective.

To improve the efficiency and precision of missile servo mechanism testing, as the research object, a certain missile servo mechanism was studied in this paper. Based on PC/104 bus and virtual instrument technique, a missile servo mechanism automatic test system was presented, and the design and development on hardware and software of the system was described in detail. The system, which is featured with its simple operation, high precision, high reliability, scalable and portable test software, has been proved to be feasible by the test result.
