Abstract

The self-locking burglar alarm for drinking drive behavior is characterized in that the driver is required to switch on the barometric switch on through the expiratory hood. The circuit of the device contains two delay circuits and an alcohol strength acquisition sensor. The warning signal of the alcohol limit is divided into a precaution signal and an alarm signal. When the alcohol reaches to the limit of the precaution signal, the driver is also warned. The values of the precaution and the alarm can change according to different situations. The excess alcohol exhalation of the driver is detected. The igniting circuit is broken through the comparison circuit and the electrical relay to reach the purpose of self-locking. The warning signal emits sound pulses and light signals to both the inside and outside of the car. When the joint of the expiratory hood and the pneumatic switch components is uninstalled and broken, the igniting circuit of the car automatically breaks, which plays the role of a burglar alarm. The two delay circuits prevent the alarming device from misreporting and guarantees that the igniting circuit is on-off appropriately according to the predefined logics so as to make the self-locking function reliable.

Description

Drive when intoxicated self-locking, warning and anti-joyride device

Technical field

The utility model relates to self-propelled vehicle, and the safety traffic control monitor unit particularly prevents to driving a car under the influence of alcohol and has the auto mat of anti-theft feature concurrently.

Background technology

According to statistics, having in the traffic accident more than 40% in the world is owing to drive when intoxicated, and the driver is off one's feet, and is slow in reacting, moves malfunctioningly, contravenes traffic regulations, and causes a serious accident.Car crash often brings great misfortune for individual and society.The traffic management system of national governments all has very severe punishment regulations for driving when intoxicated, traffic constable at the other surprise check driver's of highway breath alcohol content, prevented to drive when intoxicated during the Holiday of being everlasting.But, the traffic police to be checked through the end limited, can only play the effect of selective examination.It is few particularly to work as the traffic police, and driving for a long time can not be in large quantities, selective examination all sidedly.In recent years, occurred on the market that many drivers of allowing restrain oneself, the pocket breath alcohol concentration measurer that uses in buying car in installments.This measurer is easy to use, and everybody can be equipped with, but for automatic driver, may be utterly useless, he can not use (or because of obnubilation, failing to give attention to use), and accident goes out in the same old way.So, many patents have appearred again, and the firing circuit that alcohol content is detected this link and vehicle connects.When the driver will start vehicle, the first step was the alcohol content during test is breathed, if surpassed predefined value, the vehicle ignition circuit disconnects, and the driver can't start, and plays a protective role.There are some shortcomings in these designs, have plenty of the alcohol content (being breathed out by the driver) in the test drives room air, if too sensitive, the wine of having drunk too much among the passenger, also may false triggering report to the police, car can not be started.On cabriolet, more can not use.Individual other alcohol content measurer has also adopted by the driver and has tested with a mouthful air blowing, but has problems in the warning circuit design.At present, the limits value of the alarm set point of nearly all alcohol content measurer has only a fixed value.Some country is made up of a plurality of states, province, borough in the world, and each administrative area is often different to the limitation standard of alcohol content, and fixing dead alarm set point can cause the inconvenience in the use.In addition, the excessive annunciator of all alcohol contents does not all have the early warning point at present, and this driver after drinking who makes some be in critical conditions might reach a standard by sheer good luck, also may have an accident.If several occupants are arranged in the car, found this situation, just can change the driver immediately.This explanation is necessary to increase " early warning and alarming ", to guarantee traffic safety.Also have, all at present annunciators of driving when intoxicated only send light, sound alarm to Che Nei driver or passenger, and outer traffic police of car or other people can't know whether the driver drives when intoxicated, and can not supervise, and can't keep away sudden strain of a muscle.At last, the method for control ignition circuit is too simple in the existing patent, the flase alarm that may cause when not considering the preheating of alcohol content sensor.In the patent that has, increased theft-proof additional function, but password need be set, make thing become too complicated.If the driver has forgotten password, just can not do whatever.

The utility model technology contents

In order to have overcome above-mentioned shortcoming, the utility model adopts following solution: will detect driver's blood alcohol content, and classify the enforceable piloting procedure that must carry out as.The firing circuit of this road program and vehicle is together in series, be start car engine must be through way, the driver can not skip this road program, otherwise at all can't the starting ignition circuit.This covering device has comprised the cover of exhaling, and the driver must blow facing to this cover of exhaling with mouth, could start a pneumatic switch.Pneumatic switch and a time delay circuit link.The length of time-delay is approximately 1-2 minute.It mainly acts on is two-layer: the first, and delay signal enters the vehicle ignition circuit, wait until that driver's blood alcohol content inspection finishes, and judges automatically after driver's the driving qualification, just carries out the instruction that pneumatic switch transmits by time delay circuit.The second, be to avoid pneumoelectric sensor (being moisture sensor basically) not use for a long time, cause the alert signal of mistake by self moisture.Need about 1-2 of fore-warming time minute.This time difference is to be finished by two time delay circuits.Wherein, the time constant of alerting signal time delay circuit should be than opening the bigger of the time delay circuit that links to each other with pneumatic.Personnel's bulletin outside car during for information of same that the driver is drunk is significantly installed light and acoustic warning device in the position in the vehicle body outside.Drunk driver is placed oneself in the midst of under the common supervision of the driver in passenger and outer traffic law enfrocement official of Che and the adjacent vehicle simultaneously.Certainly, drunk light and the requirement of sound alarm appliance and the definition of lamp colr and sound type of demonstration driver is installed outside vehicle body, should works out, require all driving personnel to be familiar with and strict the execution by the authoritative department of government.

The specific embodiment

Embodiment one:

Fig. 1 has described from the driver and has entered after operator's compartment takes one's seat, and attempts to start the logical process of automobile.First pass is to give a puff to the cover of exhaling.The dynamics that the driver blows is wanted and the pneumatic switch on the air flue can be connected, electric signal divides two-way to pass to time delay circuit (1) with by dynamo-electric connecting joint arrival alcohol concentration sensor, through amplifying and time delay circuit (2), begin to detect the alcohol concentration of driver in feeling elated and exultant, judge whether to reach and forbid the degree of driving.When alcohol concentration reach legal limit 90% the time, warning device can send early warning signal, but can not cut off the firing circuit of vehicle.Enter the firing circuit of engine by the electric signal of being connected by pneumatic switch of time delay circuit (1), connect a relay switch, at this time, if the driver rotates the driving key, vehicle just can normally start.But, alcohol concentration in the driver exhales reach legal limit 100% the time, warning device can send the warning signal of drunken driving, and simultaneously, warning device can be connected a normally closed switch in the firing circuit, cut off the firing circuit of vehicle, so,, connected another relay switch even pass through the firing circuit that time delay circuit (1) arrives engine, and the driver rotates the driving key, and is also of no avail.Vehicle has pinned automatically.Played and forbidden the protective effect of drivining a car under the influence of alcohol automatically.

Below in conjunction with the structural representation of accompanying drawing 2, further describe principle of work of the present utility model to accompanying drawing 6.As shown in Figure 2, exhale cover 1 and cylindricality instrument case 2 by telescopic elastic wire 3, pass socket base 5, lead to the circular hole be arranged near car body suitable position 4 operating seat, again with ensconce the car body suitable position in the flexible well known device of flex lead 3 of controlling link to each other.Fig. 3 has represented the inner structure of mobilizable assembled unit 2: include pneumatic switch 9 and " gas-electric transducer " (being alcohol concentration sensor) 10 in the cylindricality instrument case 2.The metal spring sheet sensitive member of pneumatic switch 9 is mounted in the air communication deferent of the cover 1 of exhaling.Airflow duct communicates with " gas-electric transducer " 10.All link to each other with electric signal and the power supply electric power conductor that " gas-electric transducer " 10 produces by pneumatic switch 9 with socket 11.Socket 11 and plug 12 cooperate the electric and mechanical connection between realization and the automobile body.The cooperation of socket 11 and plug 12 should be made to such an extent that be easy to pull out, insert.For antitheft, use vehicle at every turn after, can easily assembly set 2 be taken off.The size of assembly set 2 is little, and it can be placed in clothing, the leg opening bag as key, when driving, plugs next time again.After taking off assembly set 2, automobile igniting circuit just can't be connected, and the robber can't (be equivalent to another key) under the situation of these parts vehicle launch is stolen lacking.

Driver's two effects of having blown, the first, pneumatic switch 9 is opened, first switch of switching on the ignition circuit, this just forces the driver must carry out the alcohol content inspection conscious or unconsciously.Second effect is to guarantee that the driver blows the air of capacity to gas one electric transducer, guarantees authenticity and reliability that alcohol content is checked.

After the driver blows out the air of capacity to detecting device, if he drank wine, then airborne alcohol will touch gas-electric transducer 10, when reaching the concentration of certain setting (early warning value), export lower level, trigger the early warning switch, system sends early warning signal, connect relay switch I, make warning indicator lamp 6 (amber light) flicker in the car, voice suggestion simultaneously and sound alarm device 8 can warn to driver and other passengers of Che Nei: " he drank wine ".If liquor-saturated not dark, but reached the limit of early warning.Driving allows, and for the sake of security, allows preferably among the passenger other people open, and perhaps you can have a rest, and allow wine strength drive later again.Warning system simultaneously can personnel's bulletin outside car, and alerting signal can trigger and be installed in front windshield glass 17 shown in Figure 4 and be installed in warning light 16 (amber light) and acoustic alarm 15 on the rear windshield glass 18 shown in Figure 5, sends sound, visual alarm.If the driver drinks excessive, the alcohol content in the blood surpasses authoritative institution's predetermined restricted value, for example, and 0.08% o'clock (this value, each country, the area is often inequality), export higher level, trigger formal alarm switch, system's signal that gives the alarm is connected relay switch II.Alcohol content limits value (promptly alarming a little) in the utility model can float, and can be set by the specialized agency of local transit department regulation, and vehicle user can not change privately." warning threshold value " can be determined by selected good " warning point limits value ", and be for example little by about 10% than alcohol content limit.Excessive alcohol content will start warning.So the aural warning circuit in the car is connected, siren's howling that acoustic warning device 8 has sent severe voice suggestion or has been similar to police car in the car is driving a car under the influence of alcohol to stop the driver.Urgent warning lamp 7 (redness) fast blink in the car, simultaneously, also make be contained in before, acoustic warning device 15 that rear windshield is on glass and light alarm device 14 are connected.The red light fast blink, siren's howling is narrow, its sound, light intensity is enough to make the traffic police around the 100-200 rice or the driver of other vehicles can see brightly, listens clearly.Meanwhile, from the excessive electric signal of the alcohol of gas-electric transducer a normally closed switch that is connected in series to the vehicle ignition circuit is disconnected.At this moment, after electric signal by time delay circuit (1) has surpassed selected delay time, the destination point ignition circuit, because series connected normally closed switch disconnects, firing circuit still disconnects, and can't work, vehicle is in self-locking state, this has just guaranteed that the driver can't driving a car under the influence of alcohol, and to reduce traffic accident, guarantees interior other passengers of car and drunken drivers's life security.

Under normal circumstances, because the driver can not make the alcohol-detection sensor connect after blowing, sound, light alarm device in the car, outside the car are not all worked.The still locking of the normally closed switch of engine igniting circuit, firing circuit is unimpeded, from the electric signal that sends after pneumatic switch starts through time delay circuit (1) after, make normal switch connection, so the driver can start engine with car key, vehicle launch can be driven away.

Because all included circuit all are conventional in Fig. 1 diagram of circuit, known electronic circuit, the concrete electronic circuit of the respective block diagram of not drawing in this specification sheets.

Present embodiment is to be embedded into original design when being used for the new car design, constitutes the unit design scheme.
