Urban air quality real-time monitoring system based on LoRa technology

Abstract

The invention relates to an urban air quality real-time monitoring system based on LoRa technology. According to the invention, a client sends the parameter configuration information to a cloud serveror receives the air quality information sent by the cloud server; the cloud server receives the parameter configuration information sent by the client and sends to a gateway node, or receives the airquality information sent by the gateway node and sends to the client; the gateway node receives the parameter configuration information sent by the cloud server and sends to a terminal node, or receives the air quality information sent by the terminal node and sends to the cloud server; and the terminal node collects the air quality information and sends to the gateway node. The LoRa mode with ultra-low power consumption is used by the invention for communication, therefore, the load of power supply is reduced, the battery is not required to change frequently, the maintenance period of each node device is shortened, and the node can be arranged out of doors. By means of the urban air quality real-time monitoring system based on the LoRa technology, the real-time accurate air quality monitoring in the small area of a city is realized, and the feedback can be performed timely to the user through the Internet.

Description

technical field [0001] The invention belongs to the technical field of environmental monitoring and relates to a real-time monitoring system of urban air quality based on LoRa technology. Background technique [0002] In recent years, urban environmental problems have become increasingly prominent, especially smog pollution, which has brought extremely serious impacts on human physical and mental health, production and life. It is urgent to control the smog problem and protect the air environment. The country and governments at all levels have also issued emission reduction targets. Traditional air quality monitoring transmits the air quality data of each monitoring point to the monitoring center through WIFI, 3G, Zigbee and other wireless communication methods, but this kind of system has large volume, high power consumption, and short wireless communication distance, and is limited to extremely urban areas The monitoring of a small number of locations is used as a basis f...

Problems solved by technology

Traditional air quality monitoring transmits the air quality data of each monitoring point to the monitoring center through WIFI, 3G, Zigbee and other wireless communication methods, but this kind of system has large volume, high power consumption, and short wireless communication distance, and is limited to extremely urban areas monitoring of a small number of locations and use this as a basis for deriving the pollution situation of the whole city

However, urban areas are vast, especially in modern large and medium-sized cities. There are obvious differences in air quality in different areas. The special outdoor working environment also has high requirements for power supply systems and equipment volume. The existing air quality monitoring system is real-time and accurate. sex needs to be improved
