The Study On Vehicle Terminal In Smart Logistics And To Achieve

With the rapid development of the networking technology, it will be widely applied in thelogistics industry, so it will have an information revolution in the wisdom logistics. As animportant part of wisdom logistics, the research of the vehicle terminal is the key topromoting the computerized construction of logistics. With the intelligent sensing technology,the precise positioning technology and the communication technology, logistics vehicles havebecome things which can be observed and be controlled. And with the management platform,the efficient logistics management will become possible.This paper designed and implemented a vehicle terminal which not only can get thereal-time information of the location information and vehicle status information of theterminal, but also can get and monitor the vehicle through the wireless sensor networks, andfinally can transmit the information to the backend server through wireless communications.The main work of this paper includes the following aspects:1. The design and implementation of hardware platform. This vehicle terminal has ARM9core processor; GPRS module; GPS positioning module; Bluetooth module and theZigbee wireless sensor module. And this paper design the development floor.2. The research of the key technology. This paper designs the Zigbee wireless sensornetwork to get the vehicle information, so the scheme of the design of wireless networksensor nodes wil be design of wireless network sensor nodes will be flexible. In order torealize the conversion of the data, this system designs the vehicle gateway to rewrite theinformation and realize the protocol conversion.The main technical points of this articleare:a) Vehicle wireless sensor network based on Zigbee. The design of the vehicle wirelesssensor network contains the main node module and the sub node network. The zigbeegroup network collects the vehicle state information such as goods informationthrough various sensors, then transfers to the terminal system by the zibgee nodemodule.b) The design of vehicle gateway. The gateway will override the information of sensor,GPS, bluetooth and so on, to realize the protocol conversion, and finally upload to the server through the GPRS. The design and implementation of the functionmodules.3. The design and implementation of the function modules.4. After system testing, the vehicle terminal is running well, and can finish the targetrequirements.
