Monitoring data transmission networking system and method based on 433MHz Cobweb protocol

Abstract

The invention discloses a monitoring data transmission networking system and method based on a 433MHz Cobweb protocol. A Cobweb for transmission of monitoring data is mainly formed by Cobweb sensors, a Cobweb gateway router and a server through networking, the plurality of Cobweb sensors are uniformly distributed at all positions of a monitoring environment, the Cobweb sensors are connected with the Cobweb gateway router through the 433MHz Cobweb protocol, and the Cobweb gateway router is connected with the server; and when a fault occurs in the Cobweb gateway router or a mutual communication relation between the Cobweb sensors and the Cobweb gateway router changes, a communication relation between nodes is adjusted, a new network topology structure is formed, and transmission effectiveness is guaranteed. The method provided by the invention substantially optimizes an existing Ad-Hoc network protocol and transmission mechanism, completely changes the problem that existing routing nodes cannot realize low power consumption, realizes ceaseless transmission of data in a complex monitoring environment, and has the characteristics of being robust, being simple and convenient to use, being simple to operate, having a self-healing function, and being high in adaptability.

Description

technical field [0001] The patent of the present invention is an ad hoc network method for wireless data transmission, in particular a monitoring data transmission network system and method based on the 433MHz cobweb (Cobweb) protocol. Background technique [0002] With the in-depth development of the Internet of Things technology, the requirements for wireless communication technology are getting higher and higher, and it is more inclined to develop a wireless data transmission ad hoc network method with strong adaptability and no need for management and maintenance. At present, the widely used wireless communication technologies mainly include Zigbee, Bluetooth, infrared, 433MHz and Wi-Fi, and the Zigbee protocol is widely used in industrial wireless ad hoc networks. [0003] Zigbee technology usually uses the 2.4GHz frequency band, which has a relatively short wavelength, large signal transmission attenuation, and weak diffraction ability, resulting in transmission delays...

AI Technical Summary

Problems solved by technology

[0006] Usually the number of points collected by sensor monitoring is large. In a traditional wireless sensor network, multiple sensors correspond to a wireless gateway router, which uploads data to the server; Data transmission is interrupted, resulting in data loss, seriously affecting the timeliness and reliability of monitoring

Moreover, the number of traditional ad hoc network protocol channels is small, and the network topology needs to be set by the user, resulting in poor anti-interference and environmental adaptability of the wireless transmission network, and high energy consumption for data transmission.
