The Design And Implementation Of Vehicle-Borne Information Acquisition System Based On GPS And RFID

With the society developed rapidly,people’s demand for logistics is raising day by day.The logistics industry is now facing new challenges.Traditional logistics gathering and management mode can no longer meet the requirements nowadays.However,the excessively growth of logistics industry result in many problems which are caused by the imperfection of management system.For example,the valuables lost and the hazardous chemical release in transit both will lead to serious consequences.Management mode relying on manpower is inefficient and the goods in transit are difficult to track and check.Researches on logistics collection,processing,analysis and application are needed so that the whole logistics process can be monitored.Getting the real-time status of the goods in transit can improve the efficiency of logistics management.This thesis is based on the current situation of the development of logistics informatization and aimed to design a vehicle-borne information acquisition system according to the actual scene demand.GPS and RFID are applied to locate vehicles and recognize goods inside vehicles.Besides,the combination of magnetic locks and electric relays,the combination of detectors and sensors,4G routers are added to implement the vehicle door’s access control,state judgement and data sending.To reduce the cost,the SVM classification method is applied to judge the door state instead of the detectors and sensor.In time-consuming and blocking operations like data reading,writing and transmission,multi-threading technology will be used to separate relative operations from main thread,which takes full advantage of the characteristics of multi-core processors.It improves system performance and speed up the user interface for the response.The intelligent interaction function between the driver and the logistics box is added to enhance the security level.This vehicle-borne program based on Qt frame will realize the functions above.And combined with external hardware devices,a vehicle-borne information acquisition system will be built.The system in this thesis was tested in actual scene.It is easy to operate,fully functional,operating stably,friendly interface and practical in logistic information monitoring in the process of transportation.
