Design And Implementatiqn Of The Transport Information Monitoring System Based On The Wireless Sensor Network

The safe transportation of special materials has been the focus of armed escort over the years. In order to meet the requirements of "effective protection and no accident", improve the technical standard of monitoring the escorted goods and realize the temporary monitoring of the vehicles, personnel, environment and special goods, this article designs the temporary monitoring system by applying the techniques of wireless sensor networks and Zigbee.This article is divided into two parts, namely, system design and system software and hardware according to the achievement.The main method of Information collection based upon the wireless sensor networks, information melting by the technique of Zigbee and the digital communication transportation by the3G network has been applied aiming at the elimination of the "not knowing the information of the escorted goods", and the general design plan has been achieved. This article mainly discuss the design of the software and the hardware. The hardware design has realized the environment under which the hardware can be used with the platform of perceiving node, vehicle terminal and management terminal. And the software part fulfill the perceiving node, vehicle terminal and the database.Finally, the analysis of the system states that all the index such as the pocket loss rate, error rate, and the linking quality has reached the design goal.
