摘要
基于单总线数字温度传感器的多点分布工作模式,设计并实现了一个粮堆温度监测系统.该系统可为每个传感器设置独立编号,并支持液晶显示,方便用户实时查询测点温度.系统通过串行总线与PC机通信,为粮情测控软件系统提供数据,最终完成相关分析与处理.试验证明,该系统运行稳定、可靠.
In this paper, we designed a grain depot＇ s temperature monitor system based on the multi-point dis tribution working mode of a 1-wire digital temperature sensor. The system could assign an independent code for each sensor, and was compatible to LCD display so as to facilitate the real-time temperature inquiry of the detected spot. The system was communicated with a PC through a serial bus to supply data to a grain situation monitor software system, which completed the related analysis and processing. Tests showed that the system run stably and reliably.
