Abstract

The invention discloses a gateway based on the LoRa technology. The gateway comprises a first LoRa module, a second LoRa module, a first processing unit, a second processing unit, a power management module and a solar power supply device. The first processing unit is connected with the second processing unit, the first processing unit is used for controlling the first LoRa module to communicate with a sensor under the coverage of the first LoRa module and to communicate with the second processing unit, and the second processing unit is used for controlling the second LoRa module to communicate with the sensor under the coverage of the second LoRa module. The first processing unit and the second processing unit control and communicate with the respective LoRa modules, compared with the mode of controlling two LoRa modules through a single main chip, this parallel working mode has the advantages that the LoRa data transmission timeliness and reliability are improved to a certain extent, and the network capacity of the gateway is improved.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of wireless communication, and in particular to a gateway based on Long Range wireless communication (LongRange, LoRa) technology. Background technique [0002] LoRa technology is a wireless communication technology based on linear spread spectrum modulation, which is mainly used in wireless sensor networks in the field of Internet of Things. Compared with the traditional Internet of Things communication technology, LoRa technology has the following two advantages: 1) Using linear spread spectrum modulation technology, it has a wireless receiving sensitivity of up to -148dBm, and can demodulate wireless signals lower than 20dB of noise, which makes the LoRa gateway 2) LoRa uses 7 kinds of mutually orthogonal spreading factors, so that the data transmitted at the same frequency and time with different spreading factors are different from each other. Interference, this feature greatl...
