Description

Separated type vehicle air quality detection control system and method

Technical Field

The invention relates to a vehicle air detection system, in particular to a separated vehicle air quality detection control system and a separated vehicle air quality detection control method.

Background

As vehicle technology has been gradually developed, functions of a vehicle have been increasingly improved to provide users with more comprehensive services and a comfortable driving environment in driving the vehicle. Particularly, on a high-level vehicle, a design party can increase the detection of a series of substances such as PM2.5, PM10, VOC and the like in the air inside and outside the vehicle, and make relevant regulation and control according to the detection result so as to reduce harmful substances inside the vehicle and be beneficial to the physical and mental health of passengers.

When detecting a series of data of PM2.5, PM10, etc. in the air, corresponding sensors such as PM2.5 sensor, PM10 sensor, etc. are usually used for detection and data collection. Conventional sensors require processing components to perform data processing on their analysis results to obtain specific air quality information, and the associated processing components increase the cost of the sensor and increase the space occupied by the sensor. The cost limits the quality of the processing components of the sensor, so that the sensor is easily damaged to cause the sensor to malfunction, and has the defects of inaccurate detection result and the like.

Further, the conventional sensor is affected by the performance of the processing component, has a single function, often only has the function of detecting the air quality, and is not simple and clear in display mode, so that the conventional sensor is not suitable for a user to obtain air quality information while driving. When placed in a vehicle, conventional sensors occupy the interior space of the vehicle, indirectly increasing the overall volume of the vehicle or decreasing the interior space of the vehicle, which is detrimental to the user's need for a larger volume of interior space.

The driver can obtain air quality information of different cities and regions from various weather APPs every day. However, such air quality information is far from meeting the consumer's needs. The air quality information obtained from APP reflects the average air quality for a region and cannot be accurate to the specific location of the consumer. Especially when the consumer is in a relatively closed space, such as a car, the air quality parameters of the environment in which the consumer is located may be very different from the air quality information obtained by the APP. At this point, the referential of the air quality information obtained by the APP will be greatly reduced.

Therefore, the sensor needs to be processed, the detection of the original data such as PM2.5, PM10 and the like is not affected in the processing process, the size of the sensor is reduced, the service life of the processing device is ensured, and the production cost and the use cost are reduced.
