印刷电路动态功能调测系统的设计

为了解决程控交换机生产和维护中的质量检测及故障诊断问题，本文从实用的角度出发，针对ＣＹ院自行研制开发的ＣＩＰＴ─２０００型数字程控交换机，提出了交换机用户板故障检测的方法，设计了其测试系统的硬件结构及软件结构，并用汇编语言和Ｃ语言得ｕ实现。经实际应用表明，该系统性能可靠，方法实用，井使用户板的生产和维护效率大大提高。

Design of test system for the dynamic function of the printed circuits

To solve the troubles in quality testing and fault diagnosis for producing and maintaining of the digital SPC(stored program control)switching system,in view of type CIPT-2000 SPC product, manufactured by CY college,the fault diagnosis algorithm and method of the simulated SLC(subsriber line circuit)for the SPC researched by ourselves are presented;the hardware and software structure for testing system are designed and implemented by C and assemble programs. Through practice it shows that the system is reliable,the method is practical.Efficiency of producing and maintaining on the printed circuits of SLC is greatly raised.
