Remote monitoring system and communication method thereof

Abstract

The invention provides a remote monitoring system, which can improve the communication efficiency and reduce communication costs, and a communication method thereof. The remote monitoring system comprises: a plurality of terminals providing information needed by an application; a plurality of gateway devices each with a communication unit, a storage unit and a transmission control unit; and a server capable of communicating with the gateway devices. Each gateway device communicates with a part of the plurality of terminals. The plurality of gateway devices are divided into a plurality of groups by the server. Each gateway device stores group information of the gateway device. The transmission control unit of each gateway device controls forwarding of the information from the server. When the server selects a gateway device according to an application request of a user and sends an application instruction to the gateway device, the selected gateway device receives the application instruction and forwards the application instruction to the gateway devices which can communicate with the terminals related to the application requested by the user and are in the same group with the selected gateway device.

Description

technical field [0001] The invention relates to a remote monitoring system in the Internet of Things and a communication method thereof, in particular to a communication management method of a node with a sleep function. Background technique [0002] The Internet of Things is a system that uses information technology to combine objects and objects, objects and people to form a huge network, and provides various applications on this basis. Representative application fields include intelligent transportation, intelligent buildings, etc. The Internet of Things includes three layers: perception layer, network layer and application layer. The perception layer includes various sensors and devices, etc.; the network layer provides communication functions between sensors, devices and users; the application layer provides users with various applications. [0003] Communication between items is the basis for realizing the Internet of Things, and M2M (Machine-To-Machine: Machine-to-Mac...

AI Technical Summary

Problems solved by technology

[0004] For remote monitoring systems, due to the diversity of remote terminal deployment environments, there are many restrictions on the communication methods that need to be used, such as power consumption, bandwidth, cost, etc.
