摘要
利用低功耗MSP430单片机和Si4432射频芯片收集温湿度以及大气颗粒物浓度等信息,并进行数据传输、处理和预测.该系统经过模拟信号的采集及处理、数字信号的无线传输,最终集成处理并发布,该过程在MSP430单片机和Si4322芯片以及太阳能电池的支持下完成.该系统以物理测量和大气测量技术为基本支持进行数据搜集,同时结合自行设计的软件和无线通信技术进行后续数据处理.测试表明,该系统功耗低,工作稳定,无需人工干预自组网.
The system made full use of low power chip MSP430 and Si4432 RF to achieve the ac- quisition of temperature, humidity and concentration of atmospheric particulate. The system, with the support of MSP430 microcontroller, 8i4322 chip and solar cells, started with acquisition and pro- cessing of analog signal, digital signal wireless transmission, and finally processed and published the data. The system could also achieve data transition, procession and prediction. Tests showed many advantages of the system, such as low power consumption, long life, automatic networking and so on. It could be used in the intelligent transformation of school system, and lay a solid foundation for intelligent environment.
