Abstract
The invention relates to a vehicle-mounted alcohol self-locking device. The vehicle-mounted alcohol self-locking device comprises a power supply circuit, an alcohol detecting device, a microswitch, a single-chip microcomputer processing center, a flameout control relay and an oil circuit control relay, wherein electricity is provided for the power supply circuit by a storage battery in an automobile, the alcohol detecting device and the microswitch are connected with the input end of the single-chip microcomputer processing center through signal connecting wires, and the flameout control relay and the oil circuit control relay are connected with the output end of the single-chip microcomputer processing center. When the microswitch is triggered, alcohol detection is conducted by the alcohol detecting device, detection data of the alcohol detecting device are operated through the single-chip microcomputer processing center, flameout of the automobile is achieved through the flameout control relay and the oil circuit control relay if the operated data indicate that the alcohol concentration is higher than the set alcohol concentration, and therefore social harm caused by drunk driving can be effectively avoided.
Description
Technical field
The present invention relates to a kind of self-propelled vehicle self-locking device, espespecially a kind of vehicle-mounted alcohol self-locking device.
Background technology
The harm that drunken driving brings is immeasurable, and 50%～60% traffic accident is caused by drunken driving according to statistics, and the mortality of accident is also very high.Therefore, firmly stop drunken driving and become common recognition.At present, the drunken driving phenomenon ubiquity of China, and the Main Means of restriction drunken driving remains by the on-the-spot investigation of traffic constable, it carries out alcohol detection by hand-held alcohol testing equipment to navigating mate, determine whether drunk driving of driver, drunk driving is made to Administrative Punishment, although can give drunk driving person's heightened awareness to drunk driving harmfulness by administration means, can not fundamentally solve drunk driving problem.Current, there are some vehicle-mounted alcohol detection apparatus, though can carry out alcohol detection to driver, its parts of most of detecting device are various, need multiple step just can reach testing goal, thereby can not carry out fast speed detection to driver.
Summary of the invention
The problem to be solved in the present invention is, for appeal background technology, chaufeur to be carried out to alcohol detection fast and effectively, thereby effectively prevent the traffic accident that drunk driving brings.
Use the novel technical scheme addressing the above problem to be:
A vehicle-mounted alcohol self-locking device, comprises power circuit, alcohol detecting device, micro-switch, micro controller system processing enter, flame-out control relay and oil circuit control relay.Described power circuit is powered by storage battery in automobile; Described alcohol detecting device is connected wire with micro-switch by signal and is connected with described micro controller system processing enter input end; Described flame-out control relay is connected with affiliated micro controller system processing enter mouth with oil circuit control relay.
Described power circuit, comprising: polarity protection diode, voltage stabilizing chip and filter capacitor.
Described alcohol detecting device, comprising: alcohol sensor and warning device; Alcohol detecting device is connected by wire with automotive interior electronic control system; Described alcohol sensor is arranged on gauge panel downside.
Described micro-switch adopts V-151-1C25 micro-switch; Described micro-switch is arranged on below, driver's seat.
Described micro controller system processing enter, comprises micro controller system and A and D converter ADC; Described micro controller system processing enter adopts STM8S103 micro controller system, and its operating voltage range is 2.92V～5.5V.
Prior art is compared, beneficial effect of the present invention is obvious: when chaufeur, get on the bus to be sitting in and on seat, actuate micro-switch, the gas that alcohol detecting device starts chaufeur to breathe out carries out alcohol detection, it detects data and carries out data operation by micro controller system processing enter, if service contamination shows that alcohol concentration is higher than the concentration concentration of having set, side by flame-out control relay and oil circuit control relay by automobile flameout, whole testing process rapid and convenient, avoid lengthy and jumbled testing process, therefore can effectively contain the harm that drunk driving brings.
Accompanying drawing explanation
Fig. 1 is circuit connection diagram of the present invention;
Fig. 2 is realization flow figure of the present invention.
The specific embodiment
As shown in Figure 1, the present invention relates to a kind of vehicle-mounted alcohol self-locking device, a kind of vehicle-mounted alcohol self-locking device, comprises power circuit, alcohol detecting device, micro-switch, micro controller system processing enter, flame-out control relay and oil circuit control relay.Described power circuit is powered by storage battery in automobile; Described alcohol detecting device is connected wire with micro-switch by signal and is connected with described micro controller system processing enter input end; Described flame-out control relay is connected with affiliated micro controller system processing enter mouth with oil circuit control relay.
Described power circuit, comprising: polarity protection diode, voltage stabilizing chip and filter capacitor.
Described alcohol detecting device, comprising: alcohol sensor and warning device; Alcohol detecting device is connected by wire with automotive interior electronic control system; Described alcohol sensor is arranged on gauge panel downside.
Described micro-switch adopts V-151-1C25 micro-switch; Described micro-switch is arranged on below, driver's seat.
Described micro controller system processing enter, comprises micro controller system and A and D converter ADC; Described micro controller system processing enter adopts STM8S103 micro controller system, and its operating voltage range is 2.92V～5.5V.
As shown in Figure 2, the present invention relates to a kind of vehicle-mounted alcohol self-locking device, its specific implementation flow process is as follows: the chaufeur startup automobile of sitting down, V-151-1C25 micro-switch is actuated, device starts, initialization data, alcohol detecting device is started working, the gas that its alcohol sensor is breathed out to driver carries out alcohol detection, the data that detect will be sent to micro controller system processing enter and carry out calculation process, detection signal is converted into electric signal, A and D converter ADC by micro controller system processing enter is converted into digital signal by electric signal and is resent to STM8S103 micro controller system again, the data of detection and initialization data are compared, if the data that detect are less than initialization data, return and continue to detect, form circulation, automobile normally starts, if the data of detection are greater than initialization data, the annunciator of alcohol detecting device is just reported to the police, flame-out, oil circuit control relay running that micro controller system processing enter will be controlled, and the start-up circuit of disconnection automobile, after chaufeur stops, thereby prevents drunken driving.When needs restart driving engine again, alcohol detecting device is analyzed the gas that chaufeur is breathed out, and analysis result is sent to micro controller system processing enter, and alcohol screen test result can retain 30 minutes after engine off, and chaufeur needn't all repeat this test after each of short duration parking like this.Alcohol content must not reach over 20mg/100ml.
Above content is in conjunction with concrete preferred implementation further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
