摘要
介绍一种无线温度自动监控系统,它是以MSP430单片机为核心,以CC2500收发器为射频模块并辅有一些外部元件,采用C语言编写程序,应用SimpliciTI无线通信协议组成一个小型的射频网络。工作时,各终端节点每秒自动唤醒,采集附近温度和电池电压并将数据通过射频网络送至控制节点,控制节点管理各终端并经串口发送数据至电脑屏幕显示,由此实现无线温度自动监控功能。并给出系统软硬件设计。
This paper introduces a Wireless temperature monitor system, taking MSP430 microcontroller as hardware control core, CC2500 single chip as transceiver and using some peripheral elements. Program is compiled in C language to act as expected. Based on SimpliciTI protocol, a small RF network can be made. End devices wake up every 1 s to sample temperature nearby and battery information, then send these data to access point through RF network. Access point manages every end devices and sends data to PC to be displayed. The hardware and software of the system are given in detail.
