Real-time study of remote highway snow warning technology

Snowfall directly affects the traffic safety and a lot of accidents happened every year because of the snowfall. If the traffic department can timely detect the thickness of the snow on the highway and clear the snow in time, the rate of traffic accident will reduce and won't make much trouble for people. Therefore, the research on remote real-time monitoring of highway snow will solve this problem. This device uses single chip microcomputer of STC12 series as the controller, SIM900A as communication module and will sent the data of the snow thickness monitored remotely to the traffic departments, which makes that can get real-time online warned. Using GSM communication system, snow forecast and alarm can be realized in areas covered by mobile network and it is not affected by outside conditions such as weather and terrain, which is an ideal device for early warning communication system.
