Novel hierarchical heterogeneous cross-network air quality real-time monitoring model

Abstract

The invention provides a novel hierarchical heterogeneous cross-network air quality real-time monitoring model which comprises an air quality terminal monitoring module, routing nodes, sink nodes, a 3G / 4G air quality monitoring terminal module based on a 3G / 4G wireless network communication technology, and a property data service center, wherein the property data service center is used for receiving, storing, processing and compositing air quality information. Air quality terminal monitoring modules based on the ZigBee wireless technology for fixed nodes form a local ZigBee network in an Ad-Hoc network manner; the 3G / 4G air quality monitoring terminal module based on the 3G / 4G wireless network communication technology in a dynamic monitoring area is directly communicated with a server through a 3G / 4G wireless network; the property data service center saves air quality information transmitted by the ZigBee network and the 3G / 4G network. An air quality sensor comprises a PM 2.5 sensor, an MQ 135 sensor and a temperature sensor. According to the novel hierarchical heterogeneous cross-network air quality real-time monitoring model, fixed buildings and fixed plane domains can be monitored in real time simultaneously, and air quality change situations of a certain areas can be dynamically monitored.

Description

technical field [0001] The invention belongs to the technical field of wireless network communication and embedded system, in particular to a layered heterogeneous cross-network air quality real-time monitoring model of a mobile sensor network based on ZigBee communication and 3G / 4G wireless network communication technology. Background technique [0002] Environmental problems are major issues that need to be resolved urgently in our country. Air quality monitoring is an essential link in the process of environmental protection and pollution treatment. Through air quality monitoring, we can understand the composition of air pollution, provide a basis for urban planning, and provide support for improving the environment. The development of information technology has played an important role in promoting the automation, intelligence and digitization of air quality monitoring. [0003] Existing air quality monitoring systems are mainly divided into two categories: 1) interact...

Problems solved by technology

The main disadvantage is that it is not suitable for ordinary users. Users cannot perceive the specific settings of the sensor, nor can they understand the specific functions of the information. There is no good user experience, and this type of system cannot reflect changes in data in real time.
