Wireless Sensor Network for Safe Transportation

Abstract: Since dangerous goods have special physical and chemical properties, they can easily produce explosion, fire, poisoning and other accident due to a traffic collision or hazardous leak under a complex transport condition. Compared with ordinary traffic accidents, accident of dangerous goods transportation has greater risks and subsequent influence. Due to the huge transportation equipment and high freight volumes, once the accident occurred, it will be difficult to deal with the danger in the first place. Faced with such a grim situation, this paper develops a system to achieve real- time monitoring of dangerous goods transportation based on wireless sensor network (WSN). Combined with different kind of sensors, wireless communication technology and data fusion technology, a real-time monitor system is developed for dangerous good transportation. In addition to real- time monitoring, the system can analyze the state parameters obtained to check whether the vehicle is in a safe condition. The system has a real-time tracking, monitoring and early warning function which has important significance in curbing accidents and lowering the accident loss as far as possible
