A dual-mode internet of things control system and method

Abstract

The invention discloses a dual-mode Internet of Things control system and method, and belongs to the technical field of container data communication. The system comprises a data collection module, a GPS module, a satellite communication module, an Nb-lot communication module, and an MCU control module. The data collection module is used for collecting monitoring data of a container; the GPS moduleis used for locating the container to obtain position information data of the container; the satellite communication module is in bidirectional link communication with a satellite; the Nb-lot communication module performs bidirectional link communication with a ground base station; and the MCU control module is respectively connected with the data acquisition module and the GPS module to receiveand store the monitoring data and the position information data, performs bidirectional link communication with the satellite through the satellite communication module, and performs bidirectional link communication with the ground base station through the Nb-lot communication module. According to the invention, when the container is located in an area covered by a ground network, ground communication is adopted, switching to satellite communication is realized in an area not covered by the ground network, so that the technical effect of continuously tracking and monitoring the container is achieved.

Description

technical field [0001] The invention belongs to the technical field of container data communication, and in particular relates to a dual-mode Internet of Things control system and method. Background technique [0002] A container is a component tool that can be loaded with packaged or unpackaged goods for transportation, and is convenient for loading and unloading with mechanical equipment. Containers are the main carrier of goods in international trade. At present, the goods trade on the main line of international shipping is basically transported in containers. [0003] In the existing container data communication technology, the ground network such as Nb-Iot, GSM, etc. is currently mainly used to realize the transmission of container monitoring data. Since container transmission is a long-distance cargo transmission, in the process of container transportation, only Some lands have ground network coverage, which can realize the transmission of monitoring data such as posi...

Problems solved by technology

[0003] In the existing container data communication technology, the ground network such as Nb-Iot, GSM, etc. is currently mainly used to realize the transmission of container monitoring data. Since container transmission is a long-distance cargo transmission, in the process of container transportation, only Some lands have ground network coverage, which can realize the transmission of monitoring data such as positioning, but in areas without ground network coverage, such as sea areas, it is impossible to monitor the status of containers. The state of packing is unpredictable and uncontrollable, and sometimes even transportation occurs losses, etc., resulting in large economic losses

In this way, in areas without ground network coverage, there is a blind spot in the monitoring of container status, and continuous tracking and monitoring of containers cannot be realized

[0004] To sum up, in the existing container data communication technology, there is a technical problem that there is a blind spot in the monitoring of the status of the container in the area without ground network coverage, and it is difficult to continuously track and monitor the container
