[0002] As a low-power wireless local area network standard, LoRa is a long-distance radio with the characteristics of low power consumption and long transmission distance. Under the same power consumption, the communication distance of traditional wireless radio frequency is 3-5 times larger; With the wide application of LoRa wireless technology, more and more IoT devices transmit data based on LoRa wireless network; wireless transmission has the characteristics of broadcasting, in order to avoid channel conflicts, it is very important to determine whether the LoRa channel is occupied; currently only LoRa gateway It can be determined whether the LoRa channel is occupied by channel activity detection technology, and there are some other factors affecting whether the LoRa channel is busy. The current detection technology cannot accurately determine the busyness of the LoRa channel, and the user cannot know which LoRa channels are available.

Abstract
The present invention relates to a LoRa gateway, a LoRa channel detection system and method. The method comprises: the LoRa gateway receives a channel detection instruction sent by a host computer, and performs parameter configuration on the LoRa channel according to the channel detection instruction; Based on the channel content, the channel busyness detection is carried out to obtain the channel detection results, and the detection results are sent to the host computer; the host computer analyzes and sorts the channel detection results according to the prediction weight, and displays the analysis and sorting results; the LoRa gateway is based on the channel activity detection technology. Channel detection combined with channel content to detect the channel, the host computer intelligently analyzes the detection results, and displays the busyness of the LoRa channel on the interface of the host computer, and then the user can set the channel according to the analysis conclusion, to realize the channel of the IoT device The selection provides an intuitive reference to avoid LoRa air data.
