Technical Field

The invention relates to the field of wind pavilion air monitoring, in particular to an air quality monitoring system of a wind pavilion and a monitoring method thereof.

Background

The wind pavilion is an overground structure for ventilating underground space of the subway. The wind pavilions mainly play a role in ventilation of the subway, and each wind pavilion group consists of a fresh wind pavilion, an exhaust wind pavilion, a piston wind pavilion and an outdoor unit and is equivalent to a respiratory system of a human body. The wind pavilion is generally arranged at the north and south ends of a station.

The basic size, orientation and form of the shelter are determined by the amount of air displaced and the ventilation environment.

With the problems of rapid development of domestic rail transit, improvement of cultural quality of living standard of people, narrow and closed subway space, large personnel gathering, novel coronavirus pneumonia, influenza and the like, the fresh air with high quality air index is urgently needed to enter the subway for ventilation, so that the air quality monitoring of an air source entering the underground space of the subway is very necessary.

In recent years, the phenomenon that the wind pavilion is submerged by flood into the subway sometimes occurs. It is necessary to develop an intelligent lifting wind pavilion, and has great significance to the monitoring of the air quality of the air entering and exiting the intelligent lifting wind pavilion, real-time monitoring is compared with scientific limit values, and when the air quality exceeds the limit values, an alarm signal is sent out.

With the advance of national environmental protection plans, the attention degree of indoor environments in public places is higher and higher at present, such as shopping malls, subway stations, railway stations, libraries, cinemas and other places with dense and relatively closed people stream, the indoor air quality is not ideal, and the phenomena of chest distress, dizziness, shortness of breath and the like are caused when people stay in the places for a long time, so that the method for monitoring and controlling the air quality in the public places also becomes an important factor. The definition of the indoor air quality standard of the public places mainly comes from the public place sanitation management regulations and the public place sanitation standards, wherein the air quality monitoring standards and the point arrangement requirements of the public places including shopping malls, hotel hotels, movie theaters, music halls, public traffic waiting rooms, natatoriums and the like are clearly specified.

Meanwhile, pollutants in indoor air present certain hazards to health, such as Total Volatile Organic Compounds (TVOC), ozone (O3), nitrogen oxides (NOx), and the like. The indoor air quality monitoring system is installed in the traditional public place with large flow of people and dense personnel, and the problem can be effectively solved.

Indoor air quality monitoring system possesses 24 hours on-line monitoring air contaminant's function, and the monitoring parameter includes: humiture, formaldehyde, particulate matter, VOC, sulfur dioxide, nitrogen dioxide, ammonia etc. comprehensive indoor air quality monitoring system linkage treatment equipment can ensure that people under the environment obtain healthy respiratory environment, and long-term air monitoring data also plays positive effect in pollution source investigation and treatment method effect verification simultaneously.

Due to the special position and the bearing function of the subway, the subway has larger monitoring difficulty, such as building materials, interior decoration, office supplies and the like. Along with the change of indoor temperature and ventilation, the pollutants are in dynamic change, so that the air quality in the subway can be uniformly managed according to data only by having a matched and perfect air quality monitoring system at the source.

The wind pavilion mainly plays a role in ventilation of the subway. Therefore, the quality of the air input into the subway through the wind pavilion is particularly critical. It is also necessary to monitor the air quality changes of each kiosk at each station in real time.

Therefore, it is a subject of research by those skilled in the art how to develop an air quality monitoring method for a flood-proof kiosk to ensure the quality of air exchange with the underground space, reduce environmental pollution and improve the environmental quality of public places.
