Abstract
A kind of drunk-driving prevention system, is made up of single-chip microcomputer, reset circuit, crystal oscillating circuit, power supply, sensor assembly, display module, alarm module, ignition control module；The reset circuit, crystal oscillating circuit, power supply, sensor assembly, display module, alarm module, ignition control module are connected with single-chip microcomputer respectively, constitute whole system.A kind of drunk-driving prevention system of the invention, can detect alcohol concentration in air and show and can different situations be carried out with the drunk-driving prevention system of corresponding prompting, effectively reduce the generation of traffic accident, ensure people's safety.
Description
Technical field
The present invention relates to intelligent protection system, more particularly to a kind of drunk-driving prevention system.
Background technology
After New Century, as economic develops rapidly, living standard is constantly lifted, the outgoing selection for instrument of people, also there occurs huge change, automobile also no longer as belonging to top-grade consumption before, but common people house is gradually entered into, the preferred manner as popular trip firmly improves our quality of life, but also occur in that some social concerns, such as the generation of traffic accident.And traffic accident occurs most directly, topmost reason is then driven when intoxicated, and the life that it gives people brings destructive strike.Want to avoid driving when intoxicated the generation for causing the accident, in addition to the education of awareness of safety to be strengthened and strict and meticulous laws and regulations, it is a can fundamentally prevent drunk person and start the intelligence control system of automobile just arise at the historic moment.
The content of the invention
Can detect alcohol concentration in air and show and can different situations be carried out with the drunk-driving prevention system of corresponding prompting it is an object of the invention to provide a kind of, effectively reduce the generation of traffic accident, ensure people's safety.
The purpose of the present invention is achieved through the following technical solutions：
A kind of drunk-driving prevention system, is made up of single-chip microcomputer, reset circuit, crystal oscillating circuit, power supply, sensor assembly, display module, alarm module, ignition control module；The reset circuit, crystal oscillating circuit, power supply, sensor assembly, display module, alarm module, ignition control module are connected with single-chip microcomputer respectively, constitute whole system.
The single-chip microcomputer uses STC12C5A60S52 single-chip microcomputers.
The sensor assembly uses infrared sensor.
Its workflow is：First it is that external signal is detected by infrared sensor HC-SR501, if not detecting the appearance of people, P1.0 mouthfuls of input low level, program is not performed downwards, returns and continue to detect；If detection someone, sensor exports high level, PI.0 inputs are height, after single-chip microcomputer receives high level, read the analog quantity that P1.1 mouthfuls of alcohol sensor modules A OUT pin is transmitted, by the built-in AD conversion module of single-chip microcomputer, after the magnitude of voltage conversion of consecutive variations, the magnitude of voltage of input is compared with given voltage threshold, draw comparison signal, if numerical value exceedes threshold value, comparison signal is height, regardless of the level height of P1.5 mouthfuls of input of igniting switch key, P1.4 mouthfuls all exports high, to the input of button and comparison signal in program mutually or, it is output as P1.4 messages number, relay does not work, then firing circuit shut-off；And single-chip microcomputer sounds to P1.2 mouthfuls of output high level, buzzer；P1.3 mouthfuls is output as high level, and alarm lamp is lighted；If numerical value neither works not less than threshold value, buzzer and alarm lamp, while comparison signal is low；If ignition switch button is pressed, input low level, P1.4 mouthfuls of output is low, relay conducting, lights a fire successfully；Igniting success or not, LCD12864 can show real-time concentration, but can provide different corresponding promptings to driver, if nobody occurs, show " drunk-driving prevention system
In work "；When someone occurs, in two kinds of situation：Light a fire successfully and loss of ignition；Light a fire successfully, can show " welcome is returned, and wishes that your route is happy "；Loss of ignition, then show " for household, please don't drive when intoxicated ".
Beneficial effects of the present invention：A kind of drunk-driving prevention system of the invention, can sense whether people occurs in certain region, the alcohol concentration in detection air can in real time show alcohol concentration, and different situations can accordingly be pointed out, if alcohol concentration is exceeded, corresponding alarm is also had, when alcohol concentration is not exceeded, pushing button " can light a fire; concentration over-standard, regardless of whether pushing button, cannot all be lighted a fire；The generation of traffic accident is effectively reduced, people's safety is ensured.
Brief description of the drawings
Fig. 1 is main flow chart of the invention；
Fig. 2 is overall construction drawing of the invention.
Specific embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings.
Embodiment 1
As illustrated, a kind of drunk-driving prevention system, is made up of single-chip microcomputer, reset circuit, crystal oscillating circuit, power supply, sensor assembly, display module, alarm module, ignition control module；The reset circuit, crystal oscillating circuit, power supply, sensor assembly, display module, alarm module, ignition control module are connected with single-chip microcomputer respectively, constitute whole system.
The single-chip microcomputer uses STC12C5A60S52 single-chip microcomputers.
The sensor assembly uses infrared sensor.
Its workflow is：First it is that external signal is detected by infrared sensor HC-SR501, if not detecting the appearance of people, P1.0 mouthfuls of input low level, program is not performed downwards, returns and continue to detect；If detection someone, sensor exports high level, PI.0 inputs are height, after single-chip microcomputer receives high level, read the analog quantity that P1.1 mouthfuls of alcohol sensor modules A OUT pin is transmitted, by the built-in AD conversion module of single-chip microcomputer, after the magnitude of voltage conversion of consecutive variations, the magnitude of voltage of input is compared with given voltage threshold, draw comparison signal, if numerical value exceedes threshold value, comparison signal is height, regardless of the level height of P1.5 mouthfuls of input of igniting switch key, P1.4 mouthfuls all exports high, to the input of button and comparison signal in program mutually or, it is output as P1.4 messages number, relay does not work, then firing circuit shut-off；And single-chip microcomputer sounds to P1.2 mouthfuls of output high level, buzzer；P1.3 mouthfuls is output as high level, and alarm lamp is lighted；If numerical value neither works not less than threshold value, buzzer and alarm lamp, while comparison signal is low；If ignition switch button is pressed, input low level, P1.4 mouthfuls of output is low, relay conducting, lights a fire successfully；Igniting success or not, LCD12864 can show real-time concentration, but can provide different corresponding promptings to driver, if nobody occurs, show " drunk-driving prevention system
In work "；When someone occurs, in two kinds of situation：Light a fire successfully and loss of ignition；Light a fire successfully, can show " welcome is returned, and wishes that your route is happy "；Loss of ignition, then show " for household, please don't drive when intoxicated ".
