Perceptual System of the Dangerous Goods in Transit Escort Based on WSN

For the problems such as monitoring for dangerous goods transport costs are high, sensor access is not flexible, single function, the network robustness is poor, to achieve long distance transmission is difficult, combining sensor technology, WSN technology and 3G technology, this paper has designed a perceptual system of the dangerous goods in transit escort which is flexible in structure, fast of layout, reliable for information transmission. Applications in practice show that the system has achieved the moving target location tracking and communications, environmental argument of motion detection and pre-alarm, improved the speed and responding precision of informing danger, reduced insecure incidents of dangerous goods during transport, ultimately, realized the pre-alarm function.
