Problems solved by technology

Non-real-time control nodes will allocate specific time windows for uploading data, while the time for real-time control nodes to upload data is uncertain, so the time for uploading data between non-real-time control nodes and real-time control nodes may overlap, and non-real-time control nodes When uploading data with the real-time control node through the same channel, there may be mutual interference, resulting in data loss

Embodiment Construction

[0036] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0037] The embodiment of the present invention provides a Lora communication method, such as figure 1 shown, which includes:

[0038] S100 and Lora gateway periodically collect and upload data to non-real-time control nodes through the first channel;

[0039] S200. The Lora gateway periodically queries the real-time control node for data through the second channel, and sends the control command of the gateway control device to the real-time control node through the second channel; the gateway control device can be a cloud or a host computer.

[0040] Wherein, the communication frequency of the fi...

Abstract

The invention provides a Lora communication method and a Lora communication system, and the Lora communication method comprises the steps that a Lora gateway carries out the periodic data collection and uploading on a non-real-time control node through a first channel; the Lora gateway carries out periodic data query on a real-time control node through a second channel, and sends a control instruction of a gateway control device to the real-time control node through the second channel, wherein the communication frequency of the first channel is different from the communication frequency of thesecond channel. By implementing the invention, when the Lora node uploads the data, the communication conflict between different Lora nodes can be avoided.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a LoRa communication method and a LoRa communication system. Background technique [0002] The LoraWan protocol widely used in Lora (Long Range Radio, long-distance radio) communication, due to the limitation of communication rate and transmission distance, the number of nodes covered by a single Lora gateway is limited. In situations where a large number of nodes are required, or where the distance of a single gateway cannot be fully covered, multiple Lora gateways are required. [0003] The system composed of multiple Lora gateways and nodes includes real-time control nodes and non-real-time control nodes, and the real-time control nodes and non-real-time control nodes will be connected to the same Lora gateway. Non-real-time control nodes will allocate specific time windows for uploading data, while the time for real-time control nodes to upload data is unce...
