A wearable dust detection device and method

Abstract

The invention relates to a wearable dust detection device and method, which includes a laser dust sensor, a signal amplification module, an MCU control module, a detection and correction module, a communication module, a display module, a power supply and a button. Its characteristics are: the laser dust sensor includes a laser emission end, a laser detection end, and an air flow channel; the correction module is a three-axis acceleration sensor or a thermal flow meter; the communication module can be Bluetooth or wifi. The invention also includes a wearable dust detection method, which uses a three-axis acceleration sensor or a thermal flow meter to detect the air flow rate in the air flow channel, and finally calculates the laser dust mass concentration value. In view of the need for small and compact structure of wearable devices, air inflow can be realized directly through human body movements, and dust mass concentration can be measured in real time. In practical applications, the present invention can reserve a wearing ring / buckle on the laser dust device according to the actual needs of users. / clip, or other wearing methods, the invention has accurate measurement and is easy to carry.

Description

technical field [0001] The invention belongs to the field of air quality detection, and in particular relates to a wearable dust detection device and method. Background technique [0002] With the growth of population and the development of industrialization and other factors, various pollutants and suspended particles in the air have increased significantly, leading to the generation of smog, which has caused adverse effects on people's lives and health. Monitoring of suspended particles and harmful substances in the air The demand for processing devices is becoming more and more vigorous. At the same time, people have higher and higher requirements for the detection accuracy and comfort of airborne particulate matter detection devices. As one of the means of detecting suspended particles in the air, laser detection technology is widely used in various fields. However, the traditional laser detection technology uses an air pump as the pumping element, which cannot meet the...

Problems solved by technology

However, the traditional laser detection technology uses an air pump as the pumping element, which cannot meet the requirements of use in terms of service life.

In view of the above problems, the existing technology proposes to use a fan instead of an air pump to achieve gas collection, and further correct the particle mass concentration, which can solve the problem of shortened service life of the air pump due to heat generation, but the noise problem cannot be completely solved when the fan is working at full speed; the above The method of using air pump and fan will lead to large volume and high price of purification equipment, which is not suitable for promotion in the field of vehicle-mounted and mobile portable detection, and the effect is not good; in addition, with the improvement of people's material and cultural level, people pay more and more attention to health management. Exercise improves personal health index

However, in recent years, smog has occurred frequently, and smog can easily lead to a decline in the defense function of the respiratory system and lung function. Participating in sports such as running and basketball will not only fail to achieve the purpose of strengthening the body, but may be counterproductive

Most of the time, people cannot accurately judge the air quality by their own senses. Therefore, it is urgent to develop a device that can be carried around and detect air quality anytime and anywhere, especially a portable and wearable dust detection device.
