1. what is atmospheric sailing

Atmospheric three-dimensional navigation monitoring vehicle navigation type environmental quality monitoring systemAt present, the mobile atmospheric particulate matter monitoring system for buses and taxis, which is widely used and has good effect, carries out mobile dynamic monitoring of atmospheric particulate matter pollution in the region. With the monitoring of the movement of buses and taxis in the urban area, it can not only understand the pollution situation of the whole region, but also monitor the local pollution, and realize the comprehensive monitoring from macro to micro within the region; at the same time, using advanced big data and cloud platform technology, combined with the atmospheric particulate matter pollution model, the collected data are scientifically predicted according to the law and trend of atmospheric environmental quality change, the main pollution sources causing environmental pollution are accurately traced to provide a scientific basis for pollution control from the source. On this basis, scientifically and reasonably formulate emission reduction indicators for different regions, different types of regions, and streets, and dynamically adjust the haze control plan in combination with changes in meteorological conditions, and take into account economic development while controlling pollution, and realize environmental protection. And economic development go hand in hand, improve the operability of the plan, and finally achieve the monitoring and control of air pollution prevention and control through this plan.

Hazards of 2. CO

CO is a colorless, odorless, odorless gas produced by incomplete combustion of fuel. CO can cause serious harm to the human body. According to the standards of the World Health Organization (WHO), the safe concentration of CO in the atmosphere is 90ppm, and exceeding this concentration may cause harm to the human body. However, the concentration of CO in the atmosphere is usually relatively low. In the natural environment, the CO concentration in the atmosphere is about 0.5ppm. However, in some cases, the CO concentration will increase. For example, busy streets, industrial areas or chemical plants, fire scenes, homes using gas appliances, and enclosed spaces. The factors affecting CO are: 1. Climate: Climate has a great influence on the dispersion and diffusion of CO. When the temperature is high and the humidity is low, the CO concentration is usually lower, because CO is easier to diffuse, otherwise, it is very high; 2. Traffic flow: Traffic flow has a direct impact on CO concentration. Where traffic is congested, CO concentration is higher; 3. Other substances in the atmospheric environment: other pollutants may directly affect the concentration of CO.

3. carbon monoxide detection scheme

At present, Shenzhen Science and Technology has launched a four-electrode electrochemical sensor CO-B4 that can effectively detect CO in the atmosphere. The main application directions are urban fixed monitoring stations, atmospheric network equipment, vehicle and UAV equipment, etc. In addition, it can be used in multi-function portable devices to perform uninterrupted measurement, and automatically measure the air quality changes in the path area in real time during continuous movement. The resulting signals are processed and displayed on the instrument in the form of data, or stored in memory, or the received data are transmitted to the central server for processing through GPRS to display dynamic air quality changes. It has the advantages of fast response speed, strong anti-interference ability, high resolution, good linearity and wide working range. More than two years of life.
