摘　　要：为了解决现有温度监控需要的仪表数量多,组网困难的问题,设计了一种智能多路温度巡检仪。使用STC15F2K60S2作为核心处理器,巡回检测16路温度传感器。仪表具有多种类型输入功能,可与多种类型传感器、变送器配合使用。具有测量显示、超限报警控制、数据采集记录及RS 485通信功能,方便组成监控网络,大大减少了测量仪表的数量。方案采用多项创新技术,经实际测试具有测控精确稳定和抗干扰能力强等优点。In order to solve the problems of massive instrument quantity required in temperature monitoring, and networking difficulty, an intelligent multi-channel temperature inspection instrument was designed. In the instrument, STC15F2K60S2 is taken as a core processor to inspect 16-channel temperature sensor. The instrument has muhiple types of input functions, which makes the instrument used cooperatively with many types of sensors and transmitters. With the functions of measurement display, limit alarm control, data acquisition record and RS485 communication, It is easy to build monitoring network, and reduce the number of measuring instruments greatly. A number of innovative technologies were used in the scheme. The actual test indicates that the instrument has the advantages of stable control accuracy, strong anti-jamming ability, etc.
