一 引言微型计算机用在检测系统的典型框图如图1所示。图1的微型计算机用来代替早期巡迥检测机的组合逻辑电路,并且充分利用微型计算机的性能,以增加常规巡迥检测机的数据处理及存储等功能。这种系统体积小、功耗低、可靠性高、功能强,而且造价低,是巡迥检测机产品换代及 An introduction Microcomputer used in the detection system typical block diagram shown in Figure 1. The microcomputer of FIG. 1 is used to replace the combinational logic circuit of the early tour inspection machine and make full use of the performance of the microcomputer to increase functions of data processing and storage of the conventional touring inspection machine. This system is small, low power consumption, high reliability, strong function, and low cost, is a tour inspection machine replacement and
