Problems solved by technology

[0004] 1) A high-cost LoRaWAN 8-channel gateway and a LoRaWAN protocol processing server are required;
[0005] 2) In the case of fewer terminals, the cost of configuring the gateway is relatively large;
[0006] 3) For mobile and portable scenarios, the large size of the gateway is obviously not applicable;
[0007] 4) When multiple terminals have network access requirements or data transmission requirements, it takes a long time to access the network and the transmission rate is low

Embodiment Construction

[0042] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0043] See attached manual figure 1 The flow chart of the data transmission method of the gateway and terminal ad hoc network based on LoRa technology is shown. Both the gateway and the terminal use the SX1262 radio frequency chip. The execution process is as follows:

[0044] A random channel with low noise floor in gateway N (channel number=(radio frequency-470.3MHz) / 0.2MHz), and monitor it with SF10, the value of N channel is betwe...

Abstract

The invention discloses a LoRa technology-based gateway and terminal ad hoc network data transmission method. The gateway receives the network access of LoRa terminal equipment on a certain channel N that meets the requirements of the noise floor threshold, and reaches a certain level according to the signal strength of the network access request. When the threshold is required, it determines that the network access is successful and saves the ID of the terminal, and returns a successful network access response on the channel M, and then the terminal sends service data on the N channel and receives data on the M channel. The invention has low networking cost, simple process of realizing the self-organizing network mode, many terminals can complete the network access in a short time, and the network access mode is more flexible.

Description

technical field [0001] The invention belongs to the technical field of the Internet of Things, and relates to a data transmission method of a gateway and a terminal ad hoc network based on LoRa technology. Background technique [0002] LoRa is one of the low-power wide area network communication technologies, and is an ultra-long-distance wireless transmission technology based on spread spectrum technology proprietary to Semtech. LoRaWAN is a set of communication protocols and system architecture designed for LoRa long-distance communication network. It is a media access control (MAC) layer protocol. LoRaWAN is only needed for large-scale IoT network data collection. At the same time, LoRaWAN's use technology and management platform technology are more complex and require certain technical accumulation. [0003] Using LoRaWAN has the following drawbacks: [0004] 1) High-cost LoRaWAN 8-channel gateway and LoRaWAN protocol processing server are required; [0005] 2) In th...
