LoRa-Mesh-based building communication system and building communication ad hoc network method

Abstract

The invention belongs to the technical field of Internet-of-Things communication, and particularly relates to a LoRa-Mesh-based building communication system and a building communication ad hoc network method. A sensor in the system is used for sending data collected from third-party equipment in a building to a node; the node is used for transmitting data to the gateway; the gateway is arranged at a certain position according to the height of the building and is used for transmitting the data to the cloud; the cloud is intensively deployed on the public cloud and is used for distributing thedata to a corresponding third-party application server outside the building according to the characteristics of the data message, wherein the nodes and the gateway are continuously powered by a powersupply, the communication protocol of the nodes and the gateway is LoRa, a routing protocol is RPL, and Mesh networks are automatically formed between different nodes and between the nodes and the gateway through the RPL protocol. According to the invention, the protocol of the sensor can be converted into Bluetooth from LoRa, the cost of the Bluetooth sensor is lower, and the service life of theBluetooth sensor is longer; and the RPL protocol is adopted, so that the gateways can communicate with each other, automatic networking is realized, and the construction and maintenance cost is reduced.

Problems solved by technology

In practical applications, due to the complex structure of some buildings, the traditional LoRa networking method uses a star topology, which has many shortcomings, such as being unable to provide a truly universal connection for the entire building, especially in special areas such as basements, due to the duty cycle Limitations and poor link quality, often resulting in data loss and difficulty using the network
