芯片电装前的测试是保障系统的可靠性和稳定性的重要前提.介绍了一种针对国内生产的M128-554通讯处理器模块的测试方法.分析了模块的特性，构建了以PC机为控制核心、被测模块M128-554、模拟4串口信号的单片机CPU TM128、两个4串口通讯芯片16C554等组成的自动化测试平台.结合C51语言、Borland C++builder6.0语言完成了测试系统的设计与实现.叙述了具体方案设计和测试方法.%Chips are tested before electrical installation, which is an important precondition to ensure the reli⁃ability and stability of systems. A test method of M128-554 communications processor module produced in do⁃mestic is introduced. The characteristics of the module are analyzed. An automatic testing platform which in⁃cludes a PC controlling center, a tested module M128-554, a microcontroller CPU TM128 with 4 serial ports sim⁃ulation signal and two 16C554 chips with 4 serial ports communication capability is built. Combined with C51 language and Borland C++builder6.0 language, design and implementation of the test system are completed. The detailed design schemes and testing methods are described.
