摘要
为实时准确地测量道路能见度,提出了一种基于无线传感器网络的透射式能见度测量系统的设计方案。在阐述能见度测量原理的基础上,设计了以CC2430为核心,由ADS1218、OPT101、LM35、激光器等构成的硬件电路,并完成了软件系统设计。测量系统分为接收模块与远程发射模块,通过无线传感器网络来进行激光收发控制。作为交通气象站的一个传感器节点,系统具有组网灵活、通信可靠、成本低、功耗小等特点。
Aimed at detecting the visibility accurately at real-time, an improved transmission visibility measurement system was introduced. On the basis of the principle of visibility measurement, the hardware system was designed with CC2430, ADS1218, OPT101, LM35 and the laser, and the software was designed by using C language and ZigBee technology. The measurement system was made up of the receiving module and transmitting module, and communicating with WSN. As a sensor node in traffic meteorological station, this system has features on flexible networking, good adaptability, reliable communications, and low cost and low power consumption.
