Description

{Smart Respirator Protective Equipment}

The present invention relates to a smart respiratory protection device, and more particularly, to a smart respiratory protection device that includes a filter module for blocking fine particles and noxious gas, a light source module for increasing the discrimination of the wearer, a module for measuring wearer condition and air quality, The present invention relates to a technology for implementing a smart respirator of high reliability with a module for detecting position information.

As domestic and foreign environmental regulations have been strengthened, technical attempts and efforts have been made to prevent or reduce environmental pollutants, but it is practically impossible to prevent pollution sources at the source. In particular, the domestic air pollution, which is the air pollutant from China, continues to flow through the westerlies and the quality of the atmosphere has deteriorated rapidly. In addition to the above-mentioned external factors, in order to reduce air pollutants generated from internal sources such as automobiles and stationary sources such as power generation facilities, Since fermentation can not be done, the demand for personal protective equipment is steadily increasing.

Air pollutants can be divided into two categories: nitrogen oxide and fine dust. First, the nitrogen oxides are NO, NO ₂ , N ₂ O, N ₂ O ₄ , And the greatest damage is related to the generation of photochemical smog, which reacts with hydrocarbons in the presence of sunlight to produce photochemical oxides. It is also estimated that about 40% of the acid rain is due to nitric acid, which is converted to nitrate and nitrate, which cause acid rain as well as greenhouse effect. In addition, hemoglobin has a strong adsorption capacity of 20,000 times that of O ₂ , which is known to be a serious hazard when the concentration is high. Nitrogen oxide emission rates by source were 49% for automobiles, 30% for industrial plants, 15% for power plants, and 6% for heating. The effects of NO ₂ in NO ₂ can cause respiratory or pulmonary dysfunction even at very low concentrations and can lead to death if exposed to concentrations of several hundred ppm. Nitrogen oxides are emitted from fuel NOx caused by combustion of nitrogen component present in fuel oil, Prompt NOx generated in the vicinity of flame surface in the presence of hydrocarbons, and thermal NOx generated during combustion process between air and fuel oil in high temperature region do. do. In order to reduce the emission of nitrogen oxide, which is the main cause of the above-mentioned urban air pollution, regulations are being regulated in various countries around the world. In the case of neighboring Japan, the regulated values of newly installed large gas, petroleum and coal combustion power plants are 60, 130 and 200ppm, respectively. However, in order to achieve the atmospheric nitrogen oxide concentration regulated by each local government, the power plant is operating below 15, 30, 60ppm, which is well below the regulation value, and the gas turbine is operating at less than 5ppm. European limits are 30-50, 55-75, 50-100ppm for power plants and 25ppm for gas turbines. Fine dusts are classified according to their physical, chemical and biological properties. Physical properties include size, mode of production, sedimentation, and optical properties. The smog generated from fossil fuel use facilities has a size of less than 1 ㎛ and the size of coal fly as 1 ~ 100 ㎛. In addition, because of its chemical or organic composition, the fine particle pollutants themselves are highly enriched with the possibility of containing harmful substances in the human body, and they are harmful to the human body if exposed directly or indirectly to particulate pollutants. do. In addition, particulate matter with particle sizes PM10, PM5.0, PM2.5 and PM1.0 can accumulate in human alveoli during respiration and these particulate contaminants can transfer toxic substances to the human body during inhalation or respiration It also acts as a mediator. As the concentration of particle morphology increases, the clock decreases, and the clock decreases with the concentration of moisture in the atmosphere and the concentration of sulfur oxides. In order to minimize the human injury caused by such air pollutants, the most widely used product is a respiratory mask, which is worn on the front face of the human face to prevent harmful substances from entering the human body through the respiratory system of the mouth and nose .

In order to overcome the disadvantage that the location information can not be confirmed in the area where GPS reception is impossible and to improve the accuracy of the location information when the location tracking module 140 is used alone, Axis acceleration sensor module 130 that removes acceleration information noise due to irregularity caused by walking vibration of the wearer 10 or movement by a certain moving means by applying a Kalman filter to the three- . The Kalman filter is an efficient infinite impulse response filter and is one of the most widely known techniques in motion prediction because it provides an optimal prediction method for a linear dynamic system with Gaussian noise. The Kalman filter uses an error observation value to estimate the state of the dynamic system and can obtain a good result even in a reception failure or a weak signal and has a generalized regression algorithm which is excellent in separation of signal and noise and can be implemented easily by a computer Therefore, it can be effectively used to remove the noise of the accelerometer. In order to obtain the position information of the wearer 10 with the 3-axis acceleration sensor module 130, it is necessary to be able to detect the moving direction and the acceleration information of the wearer 10 regardless of the direction of the accelerometer. It is necessary to convert the coordinates of the module 130 into moving body coordinates expressed by the progress and centripetal acceleration. When referred to the angle a the three-axis acceleration sensor received from the module (130) X, Y, the magnitude of the Z-axis acceleration, respectively a ^X, a ^Y, a ^Z referred to rotate around the Y-axis, than the acceleration due to gravity effects The sum vector magnitude of the X-axis and Z-axis acceleration can be summarized by the following equations (7) and (8).

The centripetal force changes only the direction of the speed, does not change its size, and similarly to the linear movement, the centrifugal force acting as a force opposite to the traveling direction acts on the accelerometer . In the next equation (11), the rotation period of the constant-velocity motion is equal to the time when the velocity vector changes direction of the acceleration a and returns to the original direction. That is, by using the velocity and the centripetal acceleration, the turning radius r can be obtained, and the changed traveling direction

Therefore, a Kalman filter is applied to remove the noise. When it is detected that the wearer (10) is stopped by using the position information of the position tracking module (140), it is determined that pure gravitational acceleration is applied and the three axis value of the three axis acceleration sensor module Coordinate to determine the progress and centripetal acceleration.
