Description

A kind of vehicle-mounted overspeed alarm device

The utility model relates between the outer other staff of the moving velocity of power actuated vehicle and Che Nei chaufeur or car about the means of communication and the device of Vehicle Speed information, is a kind of vehicle-mounted overspeed alarm device.

If the vehicle driver surpasses the maximum speed limit value of traffic authoritative department regulation in traveling process, not only can be owing to contrary to traffic regulation, be subjected to corresponding punishment (fine and record a demerit even withhold or ban driver's license), more serious consequence is to cause traffic accident, causes the heavy losses of life, property.According to statistics, in the case of the most traffic accidents, particularly personal casualty that on express highway, occur at present, sizable ratio is arranged owing to hypervelocity causes.

In order to reduce or to avoid driving hypervelocity, chaufeur to wish to have a kind of hypervelocity alarm equipment to be installed in the car, in case hypervelocity occurs, this device can be reminded or alerting driver automatically, in time takes the deceleration measure, avoids hypervelocity.Up to now, people have designed or have invented various hypervelocity alarm devices, authorize not following over one hundred kind of patent of invention or utility model patent.But so far, few patent drops into actual the use.Its reason is that the hypervelocity alarm device that has developed exists some fatal weakness, makes the driver be reluctant to adopt:

(1) many devices often involve and will carry out electric and machinery refitment to vehicle.Dispatch from the factory for one, be sold to the vehicle in client's hand, no matter from cost and on easy-to-use, problem is arranged all.Many alarm devices are based on transforms original speed meter, installs the warning circuit additional, gathers the road speed signal with the axle or the pointer of the speed meter of mechanical means in the car with the method for machinery.Not only complicated, also may have influence on the accuracy and the reliability of original speed meter.Erection work often will ask special machinery and electrical technology personnel to carry out, and the expense of taking a lot of work line makes many people be unwilling to adopt the sort of hypervelocity alarm device.In recent years, laser or radar velocity measurement have appearred utilizing in the development of technology, even with the gps satellite location, have just solved the problem of testing the speed.Thoroughly do not solve hypervelocity alarm problem.

(2) another weakness is, is restricted on the function of existing hypervelocity alarm device.On some car, the hypervelocity alarm device has been installed now, but speed limit is fixed on often on certain speed, this express highway situation for reality is unconformable.With the U.S. is example, and the speed limit velocity amplitude in each state is normally inequality.Even on same the express highway in same state, in different locations, the speed limit scope also is not quite similar.If adopt (having when dispatching from the factory) hypervelocity alarm device of installing on present some automobile, in use very big problem can take place: during this warning, reactionless; In the time of should not reporting to the police, kyoodle, make a nuisance of oneself.Therefore, some driver would rather turn off the hypervelocity alarm device that has been equipped with in the car, in the hope of peace and quiet.

(3) existing hypervelocity alarm device is only limit between Nei Chenei chaufeur and the automobile mechanical (or system) and is linked up, and the outer personnel of car can't know whether this car exceeds the speed limit (except traffic constable utilizes radar or laser camera device self-measuring).This has the potential danger from the automobile rear bump for being positioned at certain automobile fwd chaufeur that has entered hypervelocity, can exceed the speed limit to overtake because the fwd chaufeur can't be known the crude and rash ghost of back.He can't, also can not in time take any safeguard procedures.When the traffic constable of patrol is not noted (he can not at every moment notice the moving velocity of each vehicle on the highway), traffic constable can in time not give a warning to hypervelocity automobile fwd vehicle, can't remove a hidden danger.

Consider above situation, the present invention will overcome the shortcoming of three aspects above-mentioned, and it is practical to design a cover, actv., economical, hypervelocity alarm device easy to use.

Design a kind of like this vehicle overspeed alarming device, the highway speed limit that it can be fit to any area and may change at any time under steam.That is: the alarm point of hypervelocity alarm device can not immobilizing, and scalable.Simultaneously, early warning signal be arranged, make chaufeur have time enough to employ prevention or remedial measures.New device is easy to use, when being applied to the new car design, can be used as the indispensable equipment of a new car, is fused in the whole automotive system.When being installed in the automobile after sale, be independent of the instrument in the automobile that to monitor, not contact, not reequip existing speed meter.So just can not influence the accuracy and the reliability of former car instrument.Also popular,, also can in minutes install normal the use even be ignorant of the user of machinery.At last, cost-cutting, make vast vehicle owner have the ability and be willing to install.The retail valency of the hypervelocity alarm system that we produce is less than suffering half that a penalty note is imposed a fine.Certainly, take place alarm the time confidential suitable, the speed of alarm is wanted accurately conform with the industrial limits of error.Device is wanted reliable in quality, and to driver's friendliness, everybody prefers to use it.The utility model proposes a kind of technical solution that overcomes three shortcomings of warning device at present all cars.This is the analogue system that the human eyes of a cover are observed the pointer displacement in the autometer.The physical parameter that is monitored is a road speed---the pointer position by the vehicular speeds table is expressed.The device of simulation driver eyes is a kind of based on laser or the infrared light-emitting diode micro-displacement sensor (electric eye probe) as acquisition sensor.By overspeed warning point and the alarm set point (position that the speed meter pointer arrives) that sets in advance or regulated temporarily, place the top of these points (two points to be arranged the electric eye probe, want two electric eyes), in case pointer arrives the position that sets, device just flashes or acoustic alarm signal automatically.Siren's alarm song of simulation police car or simulation police or relatives' prompting sound are sent in the recording of also available IC circuit.Any instrument in this cover system and the former car does not all have direct mechanical contact, just optics contact.System has a style of one's own, and except power supply (but also self-contained battery), can work independently.If some occasion is reluctant to use this cover alarm, can be with alarm, the early warning point is made as above the velocity amplitude of the automobile limit even turn off.

Except report the driving terminal speed to Che Nei driver, the moving velocity scope of the outer personnel of the also oriented car of this device (driver of other automobiles or patrol traffic police on the road) this car of bulletin.(we are referred to as ' color is shown fast vertically hung scroll ' by color belt, for example, can show green, yellow, redness and mauve) next speed range to other vehicles or personnel's bulletin vehicle, can inform whether outer this car of people's (comprising traffic constable) of car has entered the dangerous speed interval, so that vehicle is kept away sudden strain of a muscle early before and after allowing, in time find hypervelocity driver in violation of rules and regulations for traffic constable, actv. clue and in good time warning are provided.

The beneficial effects of the utility model are fairly obvious.If overspeed alarm device of the present utility model has been installed, vehicle driving person just obtain the to know clearly auxiliary device of a cover actv. traffic safety.Early warning signal makes the driver can shift to an earlier date Quasi (being generally 5 kilometers/trail hourly) fully, prevents the overshoot of overrunning, and goes out the speed limit barrier line.The secondth, the moment that warning signal is sent is very accurate and timely.The 3rd is that the outer moving velocity for this car of Che Neiche all comes into plain view the diaphaneity height.This overspeed alarm device not only in time gives a warning to hypervelocity person in the car, and also by the outer annunciator of car, the chaufeur in the vehicle of adjacent (front and back) in time sends bulletin, makes them have time enough to dodge or avoiding action, guarantees traffic safety.Simultaneously, also safeguard the normal order of highway driving safety another efficient assistant method is provided for traffic constable.

This apparatus structure is simple, reliable, easy to use, low cost of manufacture, and economic benefit and social benefit are good.

How can understand vehicle-mounted overspeed alarm device by Fig. 1 works.When vehicle ', the speed of a motor vehicle can reflect speed of a motor vehicle size with the position of pointer on the speed meter of instrument carrier panel.Here we are as an example, selected this form of analog speed meter, if it is digital that the demonstration of car speed is adopted, groundwork of the present utility model does not still change, just want respective change on the implementation method, still drop on the utility model and adopt in direct this feature of speed measuring instrument interpretation road speed.When the pointer of speed meter when the left side moves right, if pointer is inswept by the downward light shafts of launching (can be laser or infrared ray) of micro-displacement sensor, the light that scans for the first time is that early warning overspeed alarm place sends, and represents with ' the early warning velocity ratio ' this link in the figure that rectifies.Amplified by the electric signal process that pointer displacement triggers, after the filtering, relay switch is connected, device is all worked the interior light of car and the sound and the outer visual alarm of car.Owing to be early warning, just point out character, so light is chosen as yellow, sound system can be used voice suggestion, advice earlier.If the driver does not listen advice, continue to refuel, make the speed of a motor vehicle surpass the maximum speed value of this highway section regulation, at this moment, the overspeed alarming signal just takes place thereupon, and Che Neiche demonstrates the red light flicker of emergency alarm and the strange sound that the siren utters long and high-pitched sounds outward.These alerting signals make pointer just be stopped to utter long and high-pitched sounds and flashing light by the sensor that touches early warning point at a high speed when low speed turns round once more up to driver's deceleration always in action, return to normal condition.

Explain keystone configuration, parts and the dynamo-electric connecting relation thereof of selected a kind of embodiment below in conjunction with concrete constructional drawing.Shown in Figure 2, speed of a motor vehicle monitoring device 30 is by knob 60, spiral arm 40 and be contained in high sensitivity displacement pickup 50 on the spiral arm head and displacement pickup that several indication speed range of laying along the circumference camber line is used is formed.Whole speed of a motor vehicle monitoring device is to utilize Pneumatic suction cup to be installed in securely, exactly above the glass board of speed meter top, and the center is the center-aligned with dial plate.On a camber line of the outer circumferential edge of sucker, a slidably groove 100 is arranged, the number of speed range indicator lamp 90 is determined by traffic management system.Detecting head 50 is by spiral arm 40 and knob 60 mechanical attachment.The terminal speed value of stipulating on 50 highway divisions of the position of parking according to vehicle ', selected before driving by the driver, in the running on expressway process, when running into the speed limit variation, the driver can change the alarm set point position by turning knob 60 at any time.Electric current by the probe 50 required usefulness of electric signal merit that spread out of by lead, passes the spiral arm 40 of hollow, guides in the instrument case of controller via wire socket 41 and corresponding lead again.Fig. 4 is a section-drawing of probe 50.As seen from the figure, two sensors 70 and 80 are arranged in the probe.Wherein, the 70th, the detecting early-warning overspeed signal is used, and the 80th, detection overspeed alarming signal is used, and they all can move along little chute 110, can change the relative position between them like this.This position is determined according to the warning lead that by traffic monitoring department its standoff distance is also relevant with the diameter of speed dial plate.As a kind of embodiment, can select to shift to an earlier date 5 kilometers/hour-8 kilometers/hour and send early warning signal.The structure of speed range sensor 90, principle is identical with the sensor that acts on in the probe 50.But their position is changeless, is determined by the scale relevant in the speed meter in the gauge panel and the position of the deep-slotted chip breaker of being installed.That several sensors correctly is placed on the intersection point of the scale of indicated velocity amplitude and the line of centres and arc length.Displacement pickup 70,80 and 90 etc. can utilize photounit-laser or infrared photocell-make.Also can choose known high sensitivity displacement pickup finished product, for example the sensing head of a kind of detectable great distances of selling on the market has only 2.5 mm dias, can select for use.Certainly, be not limited to above-mentioned finished product, leading indicator is highly sensitive, and is stable again, and detection range will can detect the pen travel (cutting light) that hypervelocity causes to making apart from the probe of some centimetres far away on speed meter pointer greatly exactly.Fig. 5 is the control capsule 120 of whole warning, the amplification that the inside is necessary, and filtering and relay circuit also have the light that produces alerting signal, sound device.This control capsule is linked by 12 volts of electric currents (cigarette lighter socket) of plug 130 and Che Nei.You Yang sound device louver 170 Shang the shell, early warning hypervelocity indicator lamp 140, over-speed warning light 150.Jack 160 also is sent to the various alerting signals that produce in the control capsule in the device that sends warning signal outside car on the other hand and goes by collecting on the one hand from the signal of speed monitoring device with the lead of corresponding plug.Fig. 6 expresses the installation situation of a kind of embodiment of suggestion.Speed monitor 30 is inhaled on the glass board above the gauge panel, the center of alignment speed table.After the control capsule 120 of warning inserts power socket 180, it and speed monitor 30 are coupled together with lead 190, the device that also will change color with the colour table that makes ' color is shown fast vertically hung scroll ' on being installed in the front and back windscreen is connected.Label 200 among Fig. 7 is the colour tables of ' color is shown fast vertically hung scroll ', before being installed on the windscreen 220 (can in car inside).Label 210 among Fig. 8 is identical with 200 function, different only being mounted in behind the automobile on the windscreen 230.Fig. 9 is the colour lamplight device that a kind of colour table for ' color is shown fast vertically hung scroll ' of suggestion provides color to come the display speed scope.Wherein, 201 to 205 is that a series of colored electric lamp bulbs are installed in the lamp box 200.The signal conductor of these color lamps leads in the connection box 250 in the control capsule 120.They obtain power supply by plug-socket assembly 211 to 215 respectively and accept from 216 control signals that transmit.Figure 10 is the colour table 240 of ' color is shown fast vertically hung scroll '.Colour table is divided into several regions 241 to 245 from left to right.Each zone shows a kind of predetermined color.The Electrical Engineer in erect image past utilize colour circle resistance to represent that with different colours resistance is such, need not be with digital, and people as long as seen the colour circle of resistance outside, just can know the resistance of this resistance according to the color of prior agreement and the corresponding relation between the resistance.We utilize similar notion, in the most tangible place of outside vehicle, the wind building is on glass for example, place the colour table of a slice ' color is shown fast vertically hung scroll ', provide the number of speed interval to display in advance by traffic management system, scope, the corresponding relation of the color in definition line vehicle speed and the colour table then, and this definition announced to the common people, require everybody to remember.After, as long as see color on the colour table at the exterior unified regulation of each car position, just know the approximate velocity scope that this car travels.Certainly, the speed of displaying section is too thinless too many, otherwise the common people are difficult for remembeing.Emphasis is to show the high speed interval of hazard level.For example may be defined as safe limit about 80 kilometers/hour, during less than this speed, show with green.After 80 kilometers/hour, optional several interval, for example 100 kilometers/hour, 120 kilometers/hour and greater than 120 kilometers/hour, mark off four intervals altogether and represent with green, yellow, redness and mauve respectively, relatively conform with present people's custom by left-to-right.Certainly, be not limited to above-mentioned definition, can select other definition for use, determine by traffic management system at last, bulletin.Provide the mode of color to colour table, be not limited to colour lamplight, methods such as the every physics that speed and color can be set up contact, chemistry, optics, electronics, machinery all can adopt, but will guarantee the intensity that foot moves, and round-the-clock can show.
