Design And Implementation Of Logistics Vehicle Terminal System

With the continuous upgrading of express service,increasing logistics parcels have brought great pressure to logistics enterprises and transport vehicles,the on-line tracking,remote monitoring management and driving safety of large logistics vehicles are becoming more and more prominent.At present,there are many common problems existing in the logistics and transportation industry,including: high temperature self-ignition of logistics vehicles,decentralization of remote monitoring management of vehicles,low efficiency of remote dispatching,and inconvenient wireless communication.Based on the design idea of "Internet of Things + logistics",this thesis develops a set of logistics vehicle terminal system to meet the needs of logistics vehicles and enterprise management.The main work of this thesis includes the following points:1.Through the research on the logistics transportation service system,the vehicle terminal system innovatively integrates the mainstream 4G wireless communication technology,GPS technology,sensor technology and network communication technology to achieve a full range of driving data acquisition,data analysis,protocol conversion and data interaction.2.The design and implementation of the system are divided into the vehicle data acquisition terminal,the system data protocol,the vehicle remote monitoring management and the instant communication service.This thesis starts from the hardware and software aspects of the system and details the design architecture of the system.The vehicle terminal takes advantage of ARM-Linux technology to design multi-function modules focusing on microprocessor,including the design of driving data acquisition unit,the design of communication assistant module and the design of system management module;the software part includes the design of the whole process and the realization of specific functions.The actual effect of data collection and uploading is presented through centralized monitoring management of the system backstage,and the actual effect of remote wireless communication is presented through instant messaging software.3.From the actual use point of view,this thesis has carried out the overall display and function test of the system.The test of the positioning module shows that thesystem can complete the fast search for 3D satellite in 40-80 seconds;the test of data acquisition module shows that the packet loss rate of data collection is no more than0.03%;the stability test of vehicle terminal shows that the normal operation time of the terminal can be up to 7×24 hours;the center call software test shows that the system can provide fast message broadcasting and instant messaging service;the monitoring management software test shows that the system can achieve remote centralized and efficient management of logistics fleet.The whole logistics vehicle terminal system runs well.The test results show that the logistics vehicle terminal system meets the various requirements of the logistics vehicle monitoring management.
