Fresh air system and method with indoor air intelligent detection and adjustment functions

Abstract

The invention discloses a fresh air system and method with indoor air intelligent detection and adjustment functions. A formaldehyde sensor and a benzene sensor on the window type fresh air system are used for detecting the formaldehyde content and the benzene content regularly. The formaldehyde content and the benzene content are transmitted to a control processing module through a Narrow Band Internet of Things (NB-IoT). The control processing module judges whether to turn on a fan and transmits data to a wireless terminal of a user. The user can directly set the fan turn-on threshold values through a mobile phone. If the values measured by the sensors exceed the threshold values, the fan starts to run. The user can also directly set the fan turn-on threshold values through an electronic display screen. The fresh air system with indoor air intelligent detection and adjustment functions can be mainly applied to newly decorated rooms, can conduct real-time monitoring on pollution of formaldehyde and benzene discharged from furniture in indoor air, can make a prejudgment on the indoor air and turn on the fan for ventilation in advance and also can control discharged air remotely according to the threshold values at fixed time to ensure the indoor air quality.

Description

technical field [0001] The invention relates to real-time monitoring and adjustment of indoor air by means of the Internet of Things, in particular to a fresh air system and method for detecting and adjusting indoor air through sensors, narrow-band Internet of Things, and support vector sorting machines. Background technique [0002] Indoor decoration brings two kinds of gas pollution, formaldehyde and benzene. Excessive concentration of formaldehyde can cause leukemia. Benzene poisoning can cause chest tightness, fatigue, severe coma and even death due to respiratory and circulatory failure. A slow, continuous process that can last up to ten years. At present, there are photocatalysts, bamboo charcoal bags, air purifiers and other means to remove formaldehyde on the market, but photocatalysts need to be illuminated to be effective. Bamboo charcoal bags and air purifiers are not effective in removing formaldehyde and benzene, and continuous use will make bamboo charcoal or f...

AI Technical Summary

Problems solved by technology

At present, there are photocatalysts, bamboo charcoal bags, air purifiers and other means to remove formaldehyde on the market, but photocatalysts need to be illuminated to be effective. Bamboo charcoal bags and air purifiers are not effective in removing formaldehyde and benzene, and continuous use will make bamboo charcoal or filters. Adsorption saturation, causing secondary pollution

The most effective way to remove formaldehyde is to maintain ventilation. The fresh air system can do this, but the traditional fresh air system needs to make holes in the wall, or the house that has been renovated cannot be added later, which makes the existing products still have volume Huge, complex installation and unable to intelligent control, real-time monitoring, remote operation and other issues
