Agricultural Cold Chain Logistics Monitoring Platform Based on Beidou-3 Satellite Internet of Things

Since Beidou-3 satellite navigation system has improved the communication capacity and coverage compared with beidou-2 greatly, navigation and short message of Beidou-3 satellite navigation system have broad application prospects in scenarios that cannot be covered by conventional communication methods such as monitor, alarm, emergency rescue etc. The method of 4G mobile communication plus GPS positioning is widely used in the cold chain logistics environment monitoring. In order to effectively solve the problems of data transmission, navigation and positioning in extreme environments, this paper uses the positioning and short message functions of beidou-3 satellite navigation system to design the application support platform architecture based on Satellite Internet of Things, and propose a solution to implement the application of cold chain logistics monitoring. The above method can provide full-time, all-region and high-reliability environment monitor for the transportation of agricultural products and drugs, especially in the region, such as sea, air and mountain where there is no mobile internet, and in the areas where conventional communication means cannot cover or weakly cover.
