Research On Key Technologies Of Vehicle Networking Information Service Platform Oriented To Cold Chain Logistics

Following the technological revolution and the steam power revolution,resulting in a third revolution,known as the new technological revolution,the development of Internet technology is the core application.After the Internet,the development and application of networking technology is also quietly changed the way people live.Telematics as an important branch of things,it is worth being more and more attention.Today encouraged by the state to develop cold chain logistics industry,but combined with the reality,the development of cold chain logistics industry low degree of information technology,especially the lack of supervision of the cold chain of the vehicle.So for the establishment of cold chain logistics vehicle network management platform is imperative to promote the development of cold chain logistics industry.From the cold chain logistics industry research start to produce fruits and vegetables cold chain transport as the key object of study,the status of the cold chain logistics industry at home and abroad were summarized and analyzed the needs of the cold chain logistics industry for vehicle real-time monitoring,describes the car networking technical feasibility in cold chain logistics industry,the necessity and importance.On this basis,according to the vehicle management process,the specific design of the modules and functions of the system,the main achievement of the cold chain logistics vehicle real-time positioning,vehicle trajectory monitoring,the freezer temperature and humidity monitoring and early warning functions.To achieve the above,you need to be efficient data receiving server support,in which key technologies are: based on GPS/Compass dual-mode satellite positioning technology,based on GPRS wireless communication technology,agricultural information collection based on RFID technology,based on Groovy Grails framework of technical language,based on Memcached data cache technology and mass data storage technology based on MongoDB.This paper studies the vehicle management and monitoring system uses B/S mode to Grails as a development framework to MySQL/MongoDB as the background database to achieve cold chain logistics vehicle location,vehicle storage technology track as key links were discussed.Vehicle positioning,mainly the use of GPS/Beidou satellite positioning technology,mobile communication technology,geographic information systems,mobile vehicle positioning and displayed on the electronic map,vehicle real-time monitoring.In the vehicle trajectory storage,designed for MongoDB database for storage of the mass of the driving track.In addition,vehicle management,also designed the daily business management,vehicle monitoring,query statistics,basic information management,system management five modules,and vehicle monitoring cross-reference,technically cold chain logistics vehicles supervision.Finally,on page renderings detailed display,including the administrator login display interface,order information display interface,display interface vehicle positioning,track playback display interface,temperature and humidity to achieve early warning function interface.Generally able to achieve cold chain logistics vehicle supervision and management,saving car costs,and effectively improve the efficiency of the vehicle...
