Research And Development On Vehicle Monitoring System Of Meat Cold Chain Logistics Based On BEIDOU/GPS

As China's economic construction has made encouraging achievements,the demand for food consumption of the broad masses of the people has changed to pay more attention to health and quality,and the concept has also been changed to enjoyment consumption.Which will raise higher requirements for food production enterprises in ensuring the safety of food production,transportation,sales and other aspects.Especially for meat,how to remain fresh is the most important for meat,and the solution must start from the market operation.meat source,animal husbandry,is at the first,and then to the slaughter and processing,and to be transported to the market,and finally to sales,all above is the whole process.The development history of cold chain logistics system is,and current research and technological achievements in this area is introduced in this paper,the problem which most need to be solved through the analysis and comparison of above material is put forward,including two parts-vehicle monitoring terminal and monitor ing center.In vehicle monitoring terminal,Beidou/GPS satellite positioning system is used to achieve real-time data of vehicle location,speed and other information,and transmit it to the monitoring center through GPRS wireless communication technology.This paper involves setting up the hardware architecture ?vehicle terminal software platform and programming application software and monitoring center software.The overall design of the vehicle monitoring terminal is also involved,according to the wireless communication function between vehicle monitoring terminal and host computer and the positioning function,several tests are put forward to verify whether the vehicle monitoring system meets the design requirements and normal operation.The experimental results show s that the function of the main modules is normal,which shows that the achievement of this paper can be used in the cold chain logistics system.Finally,the main contents of each chapter and completed work are summarized,and some improvement measure of vehicle monitoring terminal and monitor ing center from the point of practical application are raised,the future development direction of cold chain logistics system is also put forward.
