1. An automatic cooling and purifying method for the environment in a vehicle is characterized by comprising the following steps:

a: automatically acquiring temperature and humidity information in the vehicle at intervals by adopting a 2302DHT22 temperature and humidity sensor, automatically acquiring formaldehyde volatilization amount information in the vehicle at intervals by adopting an MS1100 formaldehyde VOC sensor, and transmitting the temperature and humidity information and the formaldehyde volatilization amount information to a microcontroller for processing;

B: when the temperature in the temperature and humidity information received by the microcontroller is not within the preset temperature range value, heating or cooling the inner space of the automobile by using the vehicle-mounted air conditioner, and stopping heating or cooling until the temperature collected again is within the preset temperature range value; when the humidity in the temperature and humidity information received by the microcontroller is lower than a preset humidity threshold value, humidifying the internal space of the automobile by using the vehicle-mounted humidifier until the humidity acquired again is higher than a preset humidity range value, and stopping humidifying;

C: when the formaldehyde volatilization amount information received by the microcontroller is larger than the safety threshold, the photocatalyst air purifier is used for starting air purification treatment work on the interior of the vehicle, and the air purification treatment work on the interior of the vehicle is stopped after 11-15 minutes when the formaldehyde volatilization amount information is lower than the safety threshold.

Technical Field

The invention relates to the technical field of in-vehicle air purification, in particular to an automatic cooling and purifying method for an in-vehicle environment.

background

With the rapid development of the current society, automobiles are indispensable vehicles for people in daily life, and particularly after people step into the automobile society in China, the number of automobile reserves is increasing day by day.

Nowadays, with the improvement of living standard of people, more and more attention is paid to the problem of environmental pollution, not only limited to automobile exhaust emission, automobile noise pollution and the like, but also the attention of people to air pollution in automobiles is increased day by day. The materials used in the interior of a vehicle contain hundreds of volatile organic compounds, including hydrocarbons, aldehydes, ketones, and the like, and can volatilize benzene-based materials such as free benzene, toluene, xylene, and various harmful materials such as formaldehyde and TVOC.

Especially in burning sun, along with the temperature rise in the car, harmful substance diffusion in the car is faster to the leakproofness of car is very strong, and door and window closes under most circumstances, is unfavorable for the diffusion of harmful gas, and this very big life safety who harms the passenger. Therefore, in daily life, people always need to open all doors of the automobile for a while before driving and then enter the automobile, which not only delays time, but also is very troublesome.

Disclosure of Invention

The invention aims to provide an automatic cooling and purifying method for the environment in a vehicle, which solves the problems that all doors of the vehicle need to be opened for ventilation before people move, the time is delayed, and the operation is very troublesome.

The invention is realized by the following technical scheme:

The automatic cooling and purifying method for the environment in the vehicle comprises the following steps:

a: automatically acquiring temperature and humidity information in the vehicle at intervals by adopting a 2302DHT22 temperature and humidity sensor, automatically acquiring formaldehyde volatilization amount information in the vehicle at intervals by adopting an MS1100 formaldehyde VOC sensor, and transmitting the temperature and humidity information and the formaldehyde volatilization amount information to a microcontroller for processing;

b: when the temperature in the temperature and humidity information received by the microcontroller is not within the preset temperature range value, heating or cooling the inner space of the automobile by using the vehicle-mounted air conditioner, and stopping heating or cooling until the temperature collected again is within the preset temperature range value; when the humidity in the temperature and humidity information received by the microcontroller is lower than a preset humidity threshold value, humidifying the internal space of the automobile by using the vehicle-mounted humidifier until the humidity acquired again is higher than a preset humidity range value, and stopping humidifying;

C: when the formaldehyde volatilization amount information received by the microcontroller is larger than the safety threshold, the photocatalyst air purifier is used for starting air purification treatment work on the interior of the vehicle, and the air purification treatment work on the interior of the vehicle is stopped after 11-15 minutes when the formaldehyde volatilization amount information is lower than the safety threshold. Further, aiming at the problems, the invention designs a method capable of automatically detecting the environment in the automobile and automatically starting to purify the environment, temperature and humidity information and formaldehyde volatilization information in the automobile are automatically collected at intervals, and a program arranged in a microcontroller is used for respectively controlling a vehicle-mounted air conditioner, a vehicle-mounted humidifier and a photocatalyst air purifier to work, so that the aim of automatically purifying the air in the automobile is fulfilled. In addition, the temperature and humidity information and formaldehyde volatilization information are collected and detected at intervals, the vehicle-mounted air conditioner, the vehicle-mounted humidifier and the photocatalyst air purifier are not always in working states, and when the environment in the vehicle returns to a normal level, the vehicle-mounted air conditioner and the vehicle-mounted humidifier can automatically stop working, so that the environment in the vehicle can be ensured to be always in an environment suitable for people to move, and excessive electric quantity can not be wasted. Because current photocatalyst air purifier start-up speed is slower, and the time that needs to purify at every turn is longer, stops to the purification work of car internal environment 11 ~ 15 minutes backs behind the formaldehyde volatility information is less than the safety threshold, and photocatalyst air purifier just automatic shutdown work can guarantee like this that the car internal environment is in low formaldehyde state for a long time, and internal environment can not resume so fast.

compared with the prior art, the invention has the following advantages and beneficial effects:

The invention relates to an automatic cooling and purifying method for the environment in a vehicle, which solves the problems that all doors of the vehicle are always required to be opened for ventilation before people move, the time is delayed, and the operation is very troublesome; and the environment in the vehicle can be ensured to be always in an environment suitable for people to move, excessive electric quantity cannot be wasted, and the vehicle has higher practicability and economic value and is very humanized.
