Embodiment Construction

[0032] Let's take an actual scene as an example. The system includes four road sections A, B, C, and D in a city, involving people E, F, G, and H. in. Specific steps are as follows:

[0033] Step 1: Install and place all the devices of the system. In road sections A, B, C, and D, it is recommended to place the gas monitoring nodes in the flowerbeds on both sides of the road, adjust the height to 50cm above the ground, package the monitoring nodes, and place the converging nodes next to the traffic lights. The whole system is adjusted to the working state, the vehicle is driving on the road, the exhaust gas (carbon monoxide) is diffused and enters the air hole of the monitoring node on the roadside, and the gas sensor converts the gas concentration into an electron flow to generate concentration data The data is sent to the aggregation node, and the aggregation node next to the road transmits the data to the background server. The background software stores, processes, and a...

Abstract

Vehicle exhaust gas pollution seriously affects daily life of urban residents accompanied with the increasingly serious urban traffic problem. The invention studies a feasible scheme for monitoring and managing exhaust gas from vehicles on roads. Based on the wireless sensor network (WSN) technology and the electrochemical sensing property of a gas sensor, the invention senses and transmits exhaust gas conditions of vehicles on roads by using a ZigBee network, collects, processes and analyzes information of each road section, and transmits a result to a corresponding department, and then the corresponding department makes real-time response. Therefore, the air quality of each road section keeps at a high level, the urban traffic is smoother, the social production efficiency is improved, the urban pollution is reduced, and the city life satisfaction is increased.

Description

technical field [0001] The invention relates to an application system for harmful gas monitoring based on Wireless Sensor Networks (WSN) technology, which is mainly used for real-time detection of carbon monoxide emission concentration in vehicle exhaust, and provides initial data for urban traffic and environmental detection. The invention belongs to the intersection field of Internet of Things technology and environmental engineering. Background technique [0002] Urbanization is developing rapidly all over the world. While people feel the rich material and spiritual life brought by urbanization, they have to face the harm brought by the increasingly serious environmental deterioration. The impact of urban air pollution on human health and the resulting economic losses have seriously restricted the development of a harmonious society, and have become one of the most concerned issues in our country and the world today. In many large and medium-sized cities in my country, d...
