Description: 该系统由主控制器、测温电路、显示电路及控制电路四大部分组成, 芯片使用了ATMEL公司的AT89S52单片机和美国DALLAS公司的DS18B20数字温度传感器。本文针对AT89S52单片机的性能和工作原理做了简单介绍；同时对测量范围在-55～+125℃之间的数字温度传感器DS18B20做了详细介绍。对软、硬件的各个模块，逐步分析设计，画出各模块流程图。经过反复的模拟运行、调试，最终实现系统功能。
该系统可应用于粮食仓储系统、楼宇自动化系统、空调系统的温度检测和生产过程监控等领域。
- The system included four major components. They were the main controller, temperature measurement circuits, display circuits and control circuits. The system used AT89S52 SCM of ATMEL Company and DS1820 digital temperature transducer of the United States DALLAS company. First of all, the book introduced the performance and working principle of SCM AT89S52 simply, at the same time, the book gave a detailed introducing about the digital temperature transducer DS1820 in which the temperature measuring scope was between-55 and+125℃.This article key to the hardware, the software composition carried on the sub-item, the modulation has analyzed the design gradually and draw flow chart of each module. After the repeatedly simulation run, the debugging, and eventually realized the system functions.
The system can be applied in grain storage systems, building automation systems, air-conditioning systems, temperature testing and production process monitoring and other fields.
