Description

technical field [0001] The invention relates to the technical field of the Internet of Things. More specifically, it relates to an Internet of Things data collection and satellite multi-mode transmission control terminal system. Background technique [0002] The Internet of Things data terminal is an application terminal that combines ground mobile communication technology and satellite communication technology in the Internet of Things. In the existing communication technology means, there are three main ways for IoT data terminals to communicate and transmit data: one is through the ground mobile communication network such as 3G or 4G network; the second is through the existing fixed network on the ground; The third is to rely on Beidou, VSAT or other satellite communication networks. The terrestrial mobile communication network or terrestrial fixed network has the advantages of fast network speed, low application cost, and small network transmission delay, so it is wide...
