摘要
介绍基于STC89C51单片机、NRF24L01射频芯片和DS18B20数字温度传感器的智能无线温度测量系统的设计,并对系统实际运行的结果数据进行测试分析。针对传统有线温度测量系统布线麻烦且成本高,布局固定不能移动的缺点,将短距离无线通信技术应用到分布式温度测量,实现了多点分布式温度测量与数据传输,并在自己设计的智能节点基础上开发自己的通信协议,最终构成一个全方位分布式的智能无线测温网络。本系统易于安装和维护,可实现规定范围内全方位的温度测量。
The paper introduce a smart wireless temperature measurement system based on the STC89C51-MCU. NRF24L01 RF chip and digital temperature sensor DS18B20. This design applies the wireless communication technology to temperature measurement system, can be effective solution for a lot of inconvenience that the temperature measurement system with cable wiring faced, to achieve a multi-point distribution, smart temperature measurement. This paper gives the analysis of the experimental data got from the actual operating system. The smart wireless temperature measurement system is easy to install and maintain, achieve a comprehensive temperature monitoring in a specialized range.
