摘要
文章给出了一种以PIC18F14K50为主控芯片，通过单总线数字温度传感器DS18820进行温度测量的硬件电路．并对温度传感器DS18820的测温过程中的主要环节进行了详细介绍。实践结果表明，工作稳定，温度测量精度达到设计要求，能够满足一般粮仓温度实时采集需要，以此为核心技术的粮情测控系统通过了国家技术专利验收。
The paper introduces a hardware circuitry of temperature measurement using PIC18F14K50 as the master chip and single-bus digital temperature sensor DS 18B20. The temperature measuring process of temperature sensor DS 18B20 is also described in detail. The results show that in practice, stability and accuracy of the design meets the requirements and the needs of temperature measurement in general granary. The measurement and control system using this design as core technology has passed the acceptance of national patents.
