A kind of Internet of things gateway and communication method of self-adaptive frequency hopping communication

Abstract

The present invention provides an adaptive frequency hopping communication Internet-of-Things gateway. The gateway comprises a main control module, and a WiFi module, a first radio frequency module and a second radio frequency module which are connected with the main control module. The WiFi module is configured to detect the signal intensity change of each channel in real time; the main control module is configured to screen out two optimal channels based on the signal intensity change of each channel to respectively control the communication of the first and second radio frequency modules and the two corresponding optimal channels. The present invention further correspondingly provides a communication method of the adaptive frequency hopping communication Internet-of-Things gateway. Themethod can achieve real-time frequency hopping according to the signal quality and can overcome the defects in the prior art.

Description

technical field [0001] The invention relates to the technical field of Internet of Things communication, in particular to an Internet of Things gateway and a communication method for adaptive frequency hopping communication. Background technique [0002] The current frequency hopping communication method of the Internet of Things mainly generates a frequency hopping channel list randomly, and according to the preset list, the sending and receiving parties perform frequency hopping communication. For example, the application numbers are 201210131865.2, 201510077742.9, 200810142296, etc. respectively disclose several common technical means of frequency hopping in the current wireless transmission technology. There are two problems in the above frequency hopping method: one is blind random frequency hopping and the target channel is not accurate enough, and the other is that this type of frequency hopping method is more suitable for point-to-point communication. When a point-to...

AI Technical Summary

Problems solved by technology

There are two problems in the above frequency hopping method: one is blind random frequency hopping and the target channel is not accurate enough, and the other is that this type of frequency hopping method is more suitable for point-to-point communication. When a point-to-multipoint star network is used, Cannot perform frequency hopping based on the signal quality of each node

In addition, the single-channel radio frequency gateway also has problems such as slow frequency hopping or even temporary interruption of communication, and the number of supported nodes is relatively small.
