Visual radio frequency perception type distributed Internet of Things gateway and system

Abstract

The invention discloses a visual radio frequency perception type distributed Internet of Things system. The visual radio frequency perception type distributed Internet of Things system comprises a gateway and a wireless node, wherein the gateway scans the wireless node to obtain an RSSI (Received Signal Strength Indicator), evaluates the communication reliability of the node within the jurisdiction range of the gateway according to the RSSI, and determines the jurisdiction gateway of the wireless node according to the reliability evaluation result. Preferably, the visual radio frequency perception type distributed Internet of Things system provided by the invention evaluates the communication reliability of the nodes within the jurisdiction of the gateway through high-frequency sampling and statistical analysis of RSSI. Preferably, the visual radio frequency perception type distributed Internet of Things system provided by the invention adopts a mesh type network architecture. The gateway optimizes the networking mode of a traditional wireless network, optimizes the disadvantage that traditional network nodes cannot be quantitatively analyzed, and enables the whole wireless networkto be more stable, reliable and visual.

Description

technical field [0001] The invention relates to the field of the Internet of Things, in particular to a visualized radio frequency sensing distributed Internet of Things gateway and system. Background technique [0002] The Internet of Things gateway usually carries various wireless communication modules, which are responsible for collecting and converting relevant data of various wireless sensors. Today's latest and most advanced complex communication technology must also coexist in a complex environment with old mobile communication systems (such as dedicated wireless communication or paging, etc.), most of which will continue to be used in the next few years; due to radio frequency The environmental instability and uncertainty of the signal, the radio frequency interference signal will bring many problems to the communication in the coverage area of ​​the wireless communication base station, even if it is a mesh network, there will usually be individual wireless nodes suc...

Problems solved by technology

Today's latest and most advanced complex communication technology must also coexist in a complex environment with old mobile communication systems (such as dedicated wireless communication or paging, etc.), most of which will continue to be used in the next few years; due to radio frequency The environmental instability and uncertainty of the signal, the radio frequency interference signal will bring many problems to the communication in the coverage area of ​​the wireless communication base station, even if it is a mesh network, there will usually be individual wireless nodes such as dropped calls, data packet loss, etc. question

The network status of traditional wireless nodes is invisible, and users cannot clearly know the status of the wireless node network they use, and cannot save data in time or implement other preventive measures when disconnection or data packet loss occurs
