Problems solved by technology

[0004] 1) In a complex environment full of high-rise buildings, such as basements, closed darkrooms, sewers and other relatively closed spaces, LoRa signals cannot be well covered
[0005] 2) In an environment where there are not many LoRaWAN wireless terminal devices deployed, deploying a gateway for these wireless terminal devices will cost a lot of money, increase the burden on the enterprise, and the gateway usage rate is low, wasting resources

Embodiment Construction

[0030] 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.

[0031] The present invention connects to the original network of LoRaWAN by means of relay search network, receives the uplink data of LoRaWAN wireless terminal equipment in fixed SF12, 471.5MHZ, and then sends data to the gateway and obtains the SF and frequency acquired after network access. The downlink data of the gateway, and then send the data to the LoRaWAN wireless terminal device in a fixed SF12, 471.5MHZ.

[0032] The relay data transmission process is as follows:

[0033] 1. The relay searches for the LoRaWAN network, and accesses the LoRaWAN network to obtain the corresponding SF and frequency;

[0034] 2. The LoRaWAN wireless terminal device failed to search the LoRaWAN network, and finally worked in SF12, 471.5MHZ;

[0035] 3. The r...

Abstract

The invention discloses a LoRaWAN complex pass-through relay implementation method. Uplink data of LoRaWAN wireless terminal equipment is received in a manner of using a relay on an SX1278 radio-frequency chip of a Semtech company; then, the data is encapsulated and sent to a gateway; downlink data of the gateway is received; after receiving the uplink data, a server analyzes and judges whether the data is relayed data or not; then, information that the relayed downlink data is added into the relay and the like is encapsulated; the encapsulated data is sent to the gateway; and the relay sends the data of a FRMPayload part to the wireless terminal equipment after receiving the downlink data. To be compatible with the original LoRaWAN network better and reduce upgrading and reconstruction of the original LoRaWAN network equipment, the invention provides four optimization schemes.

Description

technical field [0001] The invention relates to the technical field of the Internet of Things, in particular to a method for implementing LoRaWAN complex transparent transmission relay. Background technique [0002] LoRa is a low-power, long-distance IoT technology proposed by Semtech, which is widely used in wireless meter reading and other fields. LoRaWAN uses LoRa technology to build a low-power, long-distance wireless Internet wide area network. LoRaWAN benefits from the gain of spread spectrum modulation and forward error correction code, and LoRa achieves about 2 times the communication distance of cellular technology (mobile phone). [0003] LoRaWAN long-distance transmission has the following defects: [0004] 1) In a complex environment full of high-rise buildings, such as basements, closed darkrooms, sewers and other relatively closed spaces, LoRa signals cannot be well covered. [0005] 2) In an environment where there are not many LoRaWAN wireless terminal dev...
