摘要
设计了一种基于RS-485总线远程多点分布式温度监控系统,该系统通过在环境现场放置多个DS18B20数字温度传感器,利用STC89C516RD+单片机采集温度数据并显示当前温度,通过RS-485串口传回主控计算机,实现对环境现场多个分布点的温度的远程实时监测。该系统可被广泛用于粮库、仓库、矿井、机房、煤堆、花房、养鸡场等场合,有很好的使用价值。
This paper designs a remote distributed multipoint temperature monitoring system based on RS-485 bus.DS18B20 in the environmental site,and system collectes temperature data with STC89C516RD＋ and displays the current temperature,and returns the host computer with RS-485 serial port.It achieves the temperature of the environment site Multipoint real-time monitoring remotely.The system has a good value used widely in granary,warehouse,mine,the engine room,coal pile,greenhouse,chicken farm and so on.
