Automotive ventilation control system

Abstract

The invention discloses an automotive ventilation control system which comprises a controller module and a power supply battery. The input end of the controller module is connected with a carbon dioxide sensor, a smoke sensitive sensor, a temperature sensor and a key module, the carbon dioxide sensor, the smoke sensitive sensor and the temperature sensor are connected with the controller module through a signal conditioning circuit, the controller module is connected with a data storage module and a clock module, the output end of the controller module is connected with a drive circuit module I for controlling a vehicle window motor and a drive circuit module II for controlling an air conditioner motor, and the output end of the controller module is further connected with a display screen. The automotive ventilation control system is simple in structure, reasonable in design and capable of automatically controlling opening and closing of vehicle windows according to the in-vehicle air condition and timely changing in-vehicle air, enables a driver to keep clear mind and is high in practicability, and the safety of the driver and passengers is further improved.

Description

technical field [0001] The invention relates to a ventilation system, in particular to a vehicle ventilation control system. Background technique [0002] Because of its good airtightness and the long-term use of internal circulation in summer and winter, the car can easily lead to serious air pollution in the car. On the other hand, carbon dioxide is one of the normal components of human exhaled gas. However, it can make people feel dizzy and sleepy, etc. The air conditioning system in the car may also leak carbon dioxide, which affects the health of drivers and passengers, and the high temperature of the air conditioner in the car will also cause the driver to feel sleepy and sleepy, which will further lead to traffic. the occurrence of the accident. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to provide a vehicle ventilation control system, which is simple in structure and reasonable in design. Replacing the air in ...

Problems solved by technology

[0002] Due to the good airtightness of the car and the long-term use of the internal circulation in summer and winter, the air quality in the car is likely to be seriously polluted. On the other hand, carbon dioxide is one of the normal components of the human body's exhaled gas. It is not very toxic, but high concentrations of carbon dioxide However, it can make people feel dizzy, easy to fall asleep, etc. The air-conditioning system in the car may also produce carbon dioxide leakage, which affects the health of the drivers and passengers, and the temperature of the air-conditioning in the car is too high, which will also make the driver prone to drowsiness and drowsiness, which further leads to traffic accidents. the occurrence of the accident
