摘要
为了解决基于总线结构分布式温度测控系统的缺点,提出了一种基于ARM处理器的无线温度测控系统的设计方案。利用数字温度传感器DS18B20、单片机和无线通信模块构成温度测量节点,通过ARM进行数据处理及显示。介绍了温度传感器DS18B20和无线通信模块PTR2000的工作原理,并给出了系统的硬件结构及软件流程图。
In order to avoid disadvantages of distributed temperature measurement and control system based on bus, this paper introduced the design project of wireless temperature control system base on ARM processor. The temperature measurement node was consisted of digital temperature sensor DS18B20, MCU and wireless communication module, the ARM processed and displayed the acquired data. The paper also introduced the working principle of the temperature sensor DS18B20 and wireless communication module PTR2000, and presented hardware of the system and the design flow chart of software.
