Problems solved by technology
Therefore, the existing LoRa technology-based satellite IoT monitoring system does not consider carrying LoRa loads on satellites.
[0011] 3. With the implementation of 5G mobile communication and the coverage of mobile communication network in most areas of the country, the design basis of most IoT devices is based on the mobile communication network, without considering the situation of no mobile communication network
In fact, in mountainous areas, forests, lakes, oceans, and some sparsely populated areas, there is no mobile communication network coverage

The invention provides a space-based Internet of Things monitoring system and a monitoring method, in particular, a space-based Internet of Things monitoring system and a monitoring method for anti-large frequency deviation. The space-based Internet of Things monitoring system includes a satellite LORA gateway, a ground LORA terminal, a ground data control center, and a ground LORA gateway; wherein the ground LORA terminal collects data from the Internet of Things and transmits the data to the ground LORA gateway or space-based satellite LORA gateway; the ground LORA gateway and the satellite LORA gateway regularly collect the self-inspection information and status information of each ground terminal, and gather them to the ground data control center to comprehensively monitor the status of the space-based Internet of Things monitoring system; the ground data control center collects Information reported by each IoT node device and corresponding data analysis, recording, storage and display; the ground data control center sends calibration information, configuration update information and software upgrade scripts to the satellite LORA gateway to complete the software upgrade of the satellite LORA gateway , configuration update and calibration.
Description
Technical field [0001] The present invention relates to the field of networked communications space-based composition, more particularly to novel low-power days was based network monitoring system for Resistance to frequency offset. Background technique [0002] Things conventional space-based communication terminals to achieve conventional satellite communications, the satellite communication system are used and the protocols are not compatible with the terrestrial mobile radio network. Therefore, the terminal need to add additional communication system and protocol conversion module to achieve terrestrial and satellite Unicom, the only additional hardware and software costs, power consumption and cost of the communication quality of service has also been some impact. Further, the clock frequency offset between the satellite and the ground terminal, and large-scale LEO satellite earth terminals relative motion introduced by the Doppler shift are space-based communication service...
