Air pollution warning device

Abstract

The present invention relates to an air pollution alarm device comprising a lamp post, an illumination lamp, a controller, an air collection system, an air detection system, an alarm system and a weather monitoring system, the air collection system comprises a plurality groups of horizontal air collecting cover groups, an air guide tube and a plurality of air sampling tanks, the horizontal air collecting cover groups are arranged on the wall of the lamp post, and are evenly distributed along the length direction of the lamp post, the horizontal air collecting cover groups are connected with inlet ends of the air sampling tanks by sub air collection tubes, outlet ends of the air sampling tanks are connected with the air detection system by the air guide tube, the inlet ends and the outlet ends of the air sampling tanks are respectively provided with electromagnetic valves, a solar electricity generation panel is connected with a storage battery by a protection circuit, and the storage battery is connected with the controller. The air pollution alarm device has the beneficial effects that smog pollution can be effectively monitored, the air pollution on a playground can be effectively monitored, an alarm can be effectively given out, and an accurate prediction is provided for the sports activities of students.

Description

technical field [0001] The invention relates to the field of air pollution alarms, in particular to an air pollution alarm device. Background technique [0002] At present, the extracurricular activities of students in various schools in China are still dominated by outdoor playgrounds. However, with the rapid development of industry, the domestic air quality is worrying, especially in haze weather, which is the result of the interaction between specific climatic conditions and human activities. The economic and social activities of a high-density population will inevitably emit a large amount of fine particulate matter (PM 2.5). Once the emission exceeds the atmospheric circulation capacity and carrying capacity, the concentration of fine particulate matter will continue to accumulate. range of smog. Fog is an aerosol system composed of a large number of tiny water droplets or ice crystals suspended in the air near the surface. It mostly occurs in autumn and winter (this...

Problems solved by technology

[0006] Since the playground is an outdoor facility, there is no uniform standard for testing its air quality. When students go out to do morning exercises and physical exercises cannot be effectively controlled and managed. Exercising in the case of serious air pollution will cause physical damage to children. harm
