Research On The Tracking And Tracing Information System On Cold Chain Logistics Of High-end Marine Products

With the development of living and consumption levels,people’s demands for high-end marine products increased year by year,the quality requirements of high-end marine products are becoming more and more stringent,but there is still have a gap between China’s cold chain technology and foreign countries,and cold chain quality accidents occur frequently.The main reason is that the control of temperature and humidity in the logistics process is not strict,monitoring methods are not in place,the quality of marine products is destroyed.Based on this situation,this thesis develops a dedicated intelligent terminal for high-end marine products cold-chain logistics with functions of detection、transmisson、positioning、storage,and it develops an information service platform and mobile terminal applications by.NET and other software technology,the temperature and humidity data and location information can be sent to the service platform and mobile app in real time,it helps consumers or managers to keep abreast of marine products corresponding state,in order to make timely measures..The temperature and humidity of the environment was detected by the high sensitivity sensor of the intelligent terminal,and the position status of the product was located by the positioning module,then the data was transmitted to the server by GPRS,the service terminal stored the data in the database by the listening port,PC and mobile terminal software allow users to access corresponding information by calling database contents.The entire system has a real-time monitoring for cold chain logistics process to prevent the occurrence of quality accidents.In addition,the software part of the thesis had also developed a traceability of high-end marine products,people can inquire about the breeding base and other information of marine products.
