【摘要】：冷鏈運輸(Cold-chain transportation),是指在運輸過程中物品始終處于一定的低溫環(huán)境下以便使運輸物品不變質,并且可以從海、陸、空三個途徑運輸。針對目前在冷鏈運輸過程中車內溫度,位置和商品信息不能實時監(jiān)控的現(xiàn)狀,尤其是溫度信息,目前都是在車內安裝獨立溫度監(jiān)測儀,溫度數(shù)據(jù)具有滯后性,這樣就會增加食品變質的腐爛的概率,并導致相關責任的追究。RFID射頻技術在當下物聯(lián)網應用中十分廣泛,論文針對以上冷鏈運輸?shù)谋尘霸O計并實現(xiàn)了基于RFID的冷鏈物聯(lián)網應用系統(tǒng)。該系統(tǒng)主要由車載終端和監(jiān)測中心組成,車載終端由STC12C5A60S2單片機、SIM900B無線通信模塊、GPS定位模塊UBLOX NEO 6M,RFID射頻模塊和溫度采集模塊組成。監(jiān)測中心為電腦監(jiān)測終端和移動手機監(jiān)測終端。該系統(tǒng)可以完成對冷鏈運輸車內物品信息、溫度、位置等信息的實時數(shù)據(jù)采集、預處理和發(fā)送功能。通過對車載終端和監(jiān)測終端的設計,完成了各個模塊的功能連接,最后通過STC12C5A60S2開發(fā)板及相關軟硬件開發(fā)工具對RFID射頻模塊、GPS定位模塊、溫度數(shù)據(jù)采集模塊與GPRS無線傳輸模塊進行實驗測試,測試驗證了該系統(tǒng)具有對冷鏈運輸車的實時定位功能、溫度實時監(jiān)測功能,并成功將這些信息以短消息的方式無線傳輸給監(jiān)測終端設備。
[Abstract]:Cold chain transportation (Cold-chain transportation),) means that the goods are always in a certain low temperature environment in order to make the transport goods do not deteriorate, and can be transported by sea, land and air. In view of the current situation that temperature, position and commodity information can not be monitored in real time in the process of cold chain transportation, especially the temperature information, the independent temperature monitor is installed in the vehicle at present, and the temperature data is lagging behind. This will increase the probability of food spoilage and lead to accountability. RFID radio frequency technology is widely used in the Internet of things. This paper designs and implements the cold chain internet of things application system based on RFID for the background of cold chain transportation. The system is mainly composed of vehicle terminal and monitoring center. The vehicle terminal is composed of STC12C5A60S2 single chip microcomputer, SIM900B wireless communication module, GPS positioning module UBLOX NEO 6MU RFID RF module and temperature acquisition module. Monitoring center for computer monitoring terminal and mobile phone monitoring terminal. The system can collect, preprocess and send real time data of the information of goods, temperature and position in the cold chain transport vehicle. Through the design of the vehicle terminal and the monitoring terminal, the functional connection of each module is completed. Finally, through the STC12C5A60S2 development board and related software and hardware development tools, the RFID RF module and the GPS positioning module are designed. The temperature data acquisition module and the GPRS wireless transmission module are tested. The test results show that the system has the function of real time positioning and real time temperature monitoring for the cold chain transport vehicle. And the information is successfully transmitted to the monitoring terminal device by a short message.
