摘　　要：介绍以单片机AT89C2051为核心，以A／D转换器ADC0832为温度值转换芯片，16路开关选通芯片CC4067为多路温度读取选择器，MAX1487为远程通讯芯片等构成的一种温度巡回测温器。该测温器实现人－机置数、温度自动监测、温度循环显示及与上位机PC的通讯等功能，既可单独使用又可扩展用于大系统中，具有很高的性价比。Based on AT98C2051 single-chip computer, the check controller of multi-bits temperature read consists of ADC0832 A/D translator used as translation chip, CC4067 with 16 channels as the selector of multi-bit temperature read and MAX1487 as remote communication chip, etc. The temperature monitoring-detector and its functions such as controlling men-machine set data, automatic monitoring-detect of temperature, cycle display of temperature and communication with up-computer PC are introduced in the paper. The temperature monitoring-detector either single use or expand to use in big system, it has better performance and price rate.
