摘　　要：以DS18B20作为数字式实时温度传感器,以STC12C5410AD单片机为核心构建温度采集、显示、测量单元模块,根据仓库、矿井等测温场所的实际需要,组建不同规模的分布式测温网络。多个测温模块经RS-485总线联成网络,各模块温度数据通过通信接口打包发出,PC接收端按规定好的通信协议将数据解包,实现数据的集中处理、实时显示等功能,完成对现场分布域测点的温度监控。Taking DS18B20 as the real-time digital temperature sensor, STC12C5410AD as the core to build temperature acquisition, display and measure unit modules, we can build different distributed thermometric network according to actual requirement. A thermometric network is composed of multiple temperature measure modules which are connected by RS-485 bus, temperature data of each module are transmitted by communication interface and received by PC end according to communication protocols, to realize the function of data centralized processing and real-time display, to fulfill the function of temperature monitoring.
