Air quality monitoring device

This creation relates to a monitoring device, and more particularly to an air quality monitoring device.

There are many pollutants in the air. The particles floating in the air are called suspended particles and are one of the main sources of pollution. Among them, suspended particles less than or equal to 10 micrometers (μm) are called respirable suspended particles. PM ₁₀ ), suspended particles having a diameter of less than or equal to 2.5 microns are referred to as fine aerosols (PM _2.5 ). The smaller the diameter of the suspended particles, the easier it is to enter the body with the breathing, accumulating in the trachea or the lungs, resulting in different hazards of human organs.

Automobiles are currently quite popular vehicles. Because of the small space inside the car, it is easy to accumulate suspended particles, which seriously affects the air quality inside the car and endangers the health of drivers and passengers. In view of the above problems, the current method is to detect the air quality through a sensor and issue a light signal when the air quality is poor, to inform the driver that the air conditioner filter needs to be replaced or the air cleaner is turned on.

However, in actual experience, because the sensor is prone to error after a period of use, the detection result is distorted, but the driver has no way of knowing that the air quality in the car cannot be grasped in time to make appropriate countermeasures. It is necessary to improve the breakthrough.

In view of the above problems, the present invention provides an air quality monitoring device for use in a vehicle, the air quality monitoring device including a microscopic image capture device, a processing module, a display unit, a controller, and an air cleaner.

The display unit is coupled to the processing module to display particle concentration information. The controller selectively outputs the control signal based on the particle concentration information. The air cleaner is connected to the controller and activated upon receiving the control signal to reduce the concentration of aerosols in the vehicle.

In this way, the creation can instantly capture the suspended particles in the air of the vehicle through the microscopic image picker and output the image of the suspended particles, and further analyze the image of the suspended particles by the processing module to generate the particle concentration information on the display unit. In order to provide the owner with a quick view of the quality of the air inside the car. The controller then determines whether to activate the air cleaner based on the particle concentration information to maintain good indoor air quality.

The controller selectively outputs the control signal according to the particle concentration information, and the controller determines whether to output the control signal according to the particle concentration information. In an embodiment, the particle concentration information may include a current particle concentration value, and the controller outputs a control signal when the current particle concentration value is higher than the concentration set value, and if the particle concentration value is lower than the concentration set value, the controller The control signal is not output. For example, if the current particle concentration value in the car is 5 ppm and the concentration setting is 2 ppm, the controller outputs a control signal to activate the air cleaner.

In an embodiment, the particle concentration information may include a concentration change chart, and display a concentration curve that changes with time, so that the driver can immediately grasp the current air quality in the vehicle, and can know the cleaning effect of the air cleaner.

In one embodiment, the particle concentration information may include a particle analysis image, including suspended particles in a range taken by the microscopic image picker. In other words, the driver can see the actual particle image in the car through the display unit, so the information on the number, size, density and concentration of the suspended particles can be known.

In one embodiment, the controller may output a control signal when the density of the aerosol in the particle analysis image is higher than the set density. That is to say, the controller can also determine whether to output a control signal through the above-mentioned particle analysis image.

In an embodiment, the control signal can be switched to the air circulation mode of the vehicle corresponding to the air conditioning device of the control vehicle to prevent the air polluted outside the vehicle from entering the vehicle and affecting the cleaning effect of the air cleaner.

In an embodiment, the micro image capture device can also be disposed inside the air cleaner and between the air filter unit and the air outlet of the air cleaner, so that the micro image capture device can continuously capture the filtered image. Air quality.

In one embodiment, the processing module can include a wireless communication unit to transmit particle concentration information to the user device for the owner to instantly view the quality of the air in the vehicle from the remote end.

The current particle concentration value of 2, for example, in this figure, the concentration value corresponding to the end of the concentration curve 23 is about 5 ppm, so the current particle concentration value inside the vehicle 2 is 5 ppm. Alternatively, in some embodiments, the particle concentration information 21 may also display the current particle concentration value directly through the text. The particle analysis image 24 can include the aerosol 25 in the range taken by the micro image capture device 10, and the particle analysis image 24 has a scale to know the size of each of the particles 25 on the particle analysis image 24. Thereby, the driver can know the current quantity, size and density of the suspended particles 25 in the air of the vehicle based on the particle analysis image 24.
