Research On3G Wireless Communication Used In Logistics

As the continuous development and extension of3G technology,3G wirelesscommunications gradually become the support technology in communications industry,because the mobility and high bandwidth of3G technologies, making the3G technology isincreasingly integrated into the various sectors of society.This paper mainly describes the applications of3G wireless communications in thelogistics, included reduce costs, improve efficiency, and promote economic growth and otheraspects.Based on this we propose the video surveillance, logistics positioning and3G wirelessmobile office platform and so on to realize3G wireless communications in the logisticsFirstly, video surveillance of the3G wireless communications in logistics applicationsinclude monitoring of warehouse storage, access checkpoints, vehicle movement and factoryvehicle mobile surveillance and so on. Collection of video and audio information via thevideo capture, compressing the video code use the3G video server, transmitting theinformation to the management center through3G wireless network, the user can takeadvantage of wired and wireless terminal real-time remote video viewing.Secondly, based on the3G wireless communication of logistics positioning, involving3G wireless communication GPS GIS RFID logistics etc, according to logistics positioning ofthe function and processing of independence, divided into four modules: GPS managementand positioning module GIS module RFID information read3G communication module of thefour modules and the control center of communication have been through3G wirelessnetwork for the transmission of the data and video will be Dijkstra algorithm is used inlogistics positioning of the vehicles, get the vehicle running logistics optimal path, andrealized in computer the optimal path calculation.Finally, building the3G mobile office platform, video information and locationinformation via the3G network is sent to the monitoring center, in order to achieve the accessneeds of different users.Logistics management for3G wireless communication not only enhances the level oflogistics management, but also improves the efficiency of logistics management.
