| Optical fiber communication transmission equipment consists of veneers, which have specific functions, therefore detecting the quality of veneers in the equipment has great theoretical and practical significance. In this paper, by using the method of embedded software and designing software and hardware at the same time, a intelligent integrated test system to detect the LPS16A's quality of ZXMP S325 is exploited, based on pSOS.The intelligent integrated test system includes hardware system and software system. Hardware system consists of two partstOne part is all of the business veneers of ZXMP S325, which works as enviroment veneers for testing LPS16A. the other part is CPCI platform, which includes I/O module, CLK module, OS module, and CPU module. Software test system consists of the lower software and the upper software. Basing on the visual C++ 6.0 platform, the lower software program is developed by employing C++ language, and the upper software program is developed based on the pSOS's multi-task mechanism and the 32-bit microprocessor MPC852T, which can test by network and on real-time. Signals, such as circuit signals, clock signals, business signals, can be detected correctly, and results are sent to central database to store.In this paper, to reduce the development cycle of the intelligent intergated system, the lower software and the upper software are developed by using parallel methods, and insteading of the upper software with UDP soft-panel to issue orders and receive test results on the stage of debugging. By employing the method of "fault simulation" tests, the coverage and reliability of the intelligent integrated is analyzed, and the intelligent intergated system runs for some days. The experimental results show that the intelligent intergated system has some features, such as simple operation, good real-time, and high reliability. The testing mehtod of embedded software which is used in this system could be extended to other instrument's design. |
