Abstract
The invention relates to an in-vehicle air quality monitoring system. The in-vehicle air quality monitoring system comprises a PM2.5 detection module, an analog-digital converter, an infrared detector, a singlechip, a voice driver and a loudspeaker, wherein the output end of the PM2.5 detection module is connected with the input end of the analog-digital converter, the output end of the analog-digital converter is connected with the first input end of the singlechip, the output end of the infrared detector is connected with the second input end of the singlechip, the output end of the singlechip is connected with the input end of the voice driver, and the output end of the voice driver is connected with the loudspeaker. The in-vehicle air quality monitoring system can detect PM2.5 in the vehicle, and can give a prompt to persons or a driver in the vehicle in a voice alarming manner.
Description
Technical field
The present invention relates to a kind of vehicle air Quality Monitoring Control System.
Background technology
People, when using automobile, often to ignore in Automobile subenvironment to the hidden danger of health.Because automobile is a relatively little enclosure space, and the car steering time is on being everlasting several hours, and especially when long-distance travel, people have to treat time a couple of days in the space closed, and at this moment, the air quality in car seems and is even more important.What the gas index easily damaged the person was important is two, and one is PM2.5 and fine particle concentration, because particle diameter is little, is rich in a large amount of poisonous and harmful substances.
But, in existing automobile, often lack such gas analyzing apparatus.Like this, when in car, PM2.5 concentration is far longer than PM2.5 concentration outside car, driver still may close vehicle window, no matter oneself and other passengers breathe air in bad car, brings great potential safety hazard to the occupant in car.Therefore, need gas analyzing apparatus in a kind of Automobile installed in the car, the PM2.5 concentration in timely inspection vehicle in subenvironment, determine whether to need to open or close vehicle window, in service truck, air is fresh.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of vehicle air Quality Monitoring Control System, the present invention can detect the PM2.5 in car, and is pointed out occupant or driver by audio alert form.
The technical scheme solved the problems of the technologies described above is as follows:
Vehicle air Quality Monitoring Control System, it is characterized in that: comprise PM2.5 detection module, analog to digital converter, pyroscan, single-chip microcomputer, voice driven device and loudspeaker, the output terminal of PM2.5 detection module is connected with the input end of analog to digital converter, the output terminal of analog to digital converter is connected with the first input end of single-chip microcomputer, the output terminal of pyroscan is connected with the second input end of single-chip microcomputer, the output terminal of single-chip microcomputer is connected with the input end of voice driven device, and the output terminal of voice driven device is connected with loudspeaker.
Have employed such scheme; when in car being a closed space; the PM2.5 of PM2.5 detection module to interior space detects; if the PM2.5 in car is greater than or etc. the threshold value that arranges in single-chip microcomputer; single-chip microcomputer is analyzed the detectable signal coming from pyroscan; people whether is had in car to know; if draw in car the result having people; single-chip microcomputer outputs signal voice driven device; by loudspeaker sounding, occupant is warned, so that take corresponding safeguard measure of such as opening vehicle window as early as possible.
Further, also comprise communication module, ECU and display screen, the output terminal of single-chip microcomputer is connected with communication module, and communication module is connected with the input end of ECU, and the output terminal of ECU is connected with display screen.When the PM2.5 in car be greater than or etc. the threshold value that arranges in single-chip microcomputer, then illustrate that the air quality in car is provided with harmfulness to human body, while single-chip microcomputer sends alerting signal by loudspeaker, single-chip microcomputer is communicated with ECU by communication module, the occurrence of the air quality in car is delivered to ECU by communication module by single-chip microcomputer, numerical value is outputted to display screen by ECU, is shown by display screen, is poor situation by the air quality of visual form prompting driver Che Nei.
Further, also comprise a fan driver and ventilation blower fan, the input end of fan driver is connected to the output terminal of ECU, and the output terminal of fan driver is connected with ventilation blower fan.When the PM2.5 in car be greater than or etc. the threshold value that arranges in single-chip microcomputer, if driver does not improve in-car air quality by opening vehicle window after continuing for some time, then single-chip microcomputer output signal is sent to ECU by communication module, ECU controls fan driver work, thus blower fan is rotated, to accelerate air current flow, to improve the air quality in car.
Accompanying drawing explanation
It is the circuit block diagram of vehicle air Quality Monitoring Control System of the present invention in Fig. 1;
1 is PM2.5 detection module, and 2 is analog to digital converter, and 3 is pyroscan, and 4 is single-chip microcomputer, and 5 is voice driven device, and 6 is loudspeaker, and 7 is communication module, and 8 is ECU, and 9 is display screen, and 10 is fan driver, and 11 is ventilation blower fan.
