Abstract
An automatic alarm and air-exchange apparatus inside an automobile is disclosed and relates to the fields of automobile detection, signal process, electronic control, and the like. According to the utility model, the concentration of oxygen, carbon monoxide, and nicotine inside the automobile is detected by three types of gas sensors, converted into data signals through an A/D converter and an encoder, and then transmitted to a comparator for processing; and an alarm and an air discharge fan are controlled by a sequential logic control circuit. By adopting the automatic alarm and air-exchange apparatus, the integration of detecting, alarming and quick processing can be realized so that the air-exchange processing of air inside the automobile can be performed in a timely manner. The speed of the air discharging and the opening degree of an inlet valve can be adjusted based on the gas concentration detected inside the automobile so that the automatic alarm and air-exchange apparatus operates in an energy-saving manner. The automatic alarm and air-exchange apparatus is simple in design and good in economical efficiency, and fully shows the idea of human orientation by adopting the voice alarming.
Description
Technical field
The utility model relates to fields such as vehicle inspection and test, signal conditioning and electron steering, specifically is a kind of auto alarm air interchanger.
Background technology
Air-conditioning blower unit in the part automobile can't be discharged the pernicious gas in the car automatically apace; Perhaps when harmful gas concentration is low, can not detect exactly and handle and the occupant is reminded, still can work the mischief the healthy of people.
Summary of the invention
It is low that the purpose of the utility model is to solve the orthodox car accuracy of detection, and the problem that ventilation speed is slower makes up gas auto alarm air interchanger in a kind of car.This device is realized through following technical scheme: the described auto alarm air interchanger of the utility model comprises air-exhaust fan, exhaust gas oxygensensor, carbon monoxide transducer MGS1100, nicotine chemical sensor, A/D converter, coder, annunciator, blast pipe, discharge pipe etc.; This device is through the concentration of oxygen, carbonic oxide, nicotine in three kinds of gas sensor inspection vehicles; Convert it into digital signal, through the work of sequential logic control circuit control annunciator and air-exhaust fan.The utility model has the following advantages than traditional breather:
1, realized that detection, warning, fast processing are integrated, can be in time to the processing of taking a breath of gas in the car.
2, realized energy conservation through adjustment of gas concentration exhaust velocity and the open size of inlet valve that detects in the car.
3, simplicity of design, good economy performance adopts audio alert to remind and demonstrates fully the thought that people-oriented.
Description of drawings
Fig. 1 is the structural representation of auto alarm air interchanger in the said automobile of the utility model.
The specific embodiment
Structural representation below in conjunction with auto alarm air interchanger in the automobile further specifies the utility model:
As shown in the figure; This device is through the concentration of three kinds of gas sensor inspection vehicle indoor oxygens, carbonic oxide, nicotine; Convert it into digital signal and meet at the comparator processing through A/D converter, coder, through the work of sequential logic control circuit control annunciator and air-exhaust fan.This device is provided with the valve of a scalable aperture at the admission port place; 1 grade of opening angle is less than 2 grades; And in freeing pipe, set up an air flow sensor; In order to measure air flow rate in the freeing pipe, when the inner air tube flow rate reaches 1 grade, 2 grades speed of specified setting, thereby promptly stop to quicken the benefit that reaches energy-conservation.When concentration of oxygen is lower than 19.5%, annunciator will send alerting signal, and the air-exhaust fan of control circuit control simultaneously begins ventilation; When the concentration of carbonic oxide greater than 1mg/m
3Less than 3mg/m
3The time, or the concentration of nicotine is greater than 0.34 μ g/m
3Less than 3.01 μ g/m
3The time, annunciator begins to send audio alert " gas concentration has jeopardized your healthy in the car, please stops smoking immediately ", and air-exhaust fan begins startup work simultaneously, and the corresponding rotating speed of air-exhaust fan this moment is a low gear, and the opening of air intake valve is 1 grade; When the concentration of carbonic oxide greater than 3mg/m
3The time, or the concentration of nicotine is greater than 3.01 μ g/m
3The time, annunciator begins to send audio alert " gas concentration should arrive your healthy through serious threat in the car, please stops smoking immediately ", and air-exhaust fan rotating speed automatically regulating is to high speed gear simultaneously, and the opening of air intake valve is 2 grades.
The utility model patent is through detect the concentration of judging gas in the car exactly; Thereby the aperture size of the rotating speed of control air-exhaust fan and inlet port valve; The low opening of cooresponding rotating speed was little when concentration was low, and the high opening of cooresponding rotating speed was big when concentration was high, thereby had realized automatic energy saving.Audio alert also reaches the service that the personnel of riding provide hommization for the driver simultaneously.
Claims (1)
