Based On Real-time Bus Test System Design And Realization

Based on the military project "Design and Realization of Debugging Equipment System" carried by NWPU, a testing system for photoelectric detection system was researched in this article, the hardware platform and software framework of the testing system is designed, the Realization of Programming for each part and design of testing process were introduced.The architecture of the whole testing system and the solution for software are discussed to meet the testing demand. First, a basic design of the whole testing system is discussed, then with the basic design, each part of the testing system is analyzed clearly, at last, the related codes are provided, especially in the I/O subsystem part and handle control part, detail programming method is presented. The software design of the testing system is discussed detailed, a new idea is put up in human computer/man-machine interface, through repeating use buttons, the interface space is saved, the whole interface is becoming easier, more reasonable. In the design of testing process, a good method is used, which is state transition diagram design, coupled with stringent constraint conditions to ensure the stability of system testing, this new method can bring convenience and efficiency for programmers, so it can be used commonly.The test system for real-time bus designed in this paper, is easy to use, have high reliability, meet test demanding well, it is proved effective in practice.
