Public transport means internal environment air purification method

Abstract

The invention provides a public transport means internal environment air purification method which comprises a public transport means, and the public transport means is internally provided with an air purification device, a personnel existence detection system, a PM2.5 concentration monitoring device, a personnel congestion degree detection device, a control system, a plasma generator and a UV lamp. The personnel existence detection system detects whether people exist in the public transport means, the PM2.5 concentration monitoring device and the personnel crowding degree detection device detect the PM2.5 concentration and the personnel crowding degree respectively and send detection data to the control system, and the control system judges the detection data, and judges whether the air purification system, the plasma generator and the ultraviolet sterilization lamp are started or not, and then the service life of the filter element of the air purification system is prolonged.

Description

Technical field [0001] The present invention relates to the field of air purification, and in particular, a environmental air purification method within a public transport. Background technique [0002] Public transport such as subway, bus, train, aircraft, etc. As a carrier flowing, it is not only a heavy transportation task, but also shoulder an important responsibility of public safety. Due to the phenomenon in which the people in public transport is intensive, the space is small and sealed, there is a phenomenon that the internal air environment pollution is serious. There is a virus that can pass the foam and air (such as influenza virus, new crown virus, chickenpox). The carriers of viruses, measles viruses, mumps, etc.), the health and safety of passengers have a large risk, improve the satisfaction of air quality in the car, reducing the risk of aerosol virus aggregation, and is very necessary. [0003] At present, air purification equipment on the market, single function...

AI Technical Summary

Problems solved by technology

[0003] The air purification equipment currently on the market has a single function and has the following defects:

[0004] First, whether public transport is empty or fully loaded, it is always on, and the long-term operation of the air purification equipment will shorten the service life of the air purification equipment.

[0005] The second is that the purification speed of the air purification equipment cannot be intelligently adjusted according to the concentration of PM2.5, and the service life of the filter element and filter screen in the air purification equipment is short

[0006] The third is the lack of anti-virus and sterilization functions, and it is impossible to intelligently choose the way of anti-virus and sterilization according to the PM2.5 concentration and the number of people
