摘　　要：在仪器研究领域中很少见到有关多值仪器的研究。提出了一种计算机化多值仪器系统结构图 ,介绍了其双 CPU系统的性能指标和硬件设计思想及软件实现方法。根据设计的多值仪器不仅能产生多值函数信号 ,还可以测试多值逻辑电路的逻辑电平 ,分析多值逻辑电路的逻辑功能。In instrument study field there is little study of multiple-valued instrument. A kind of structural picture of computerized multiple-valued instrument is given, and the performance index of the duplex CPU system and the design thought for the hardware are introduced.At the same time the method how to use software to realize it is also introduced. The multiple-valued instrument made according to the proposed design can not only produce multiple-valued function signal, but also can test the logic level of multiple-valued logic circuits and analysis the logic function of c circuits. the multiple-valued instrument are mainly used to test the performance of multiple-valued logic system and fuzzy logic system.
