EL EL sheet principle
EL sheet is placed in luminescent powder between two plate electrodes and forms.It is sandwich type structure, respectively there is up and down an electrode, the very nesa coating ITO film that powers on, light from then on face penetrates, bottom electrode is back electrode, its material is mainly silver or carbon, and luminescent material is mainly zinc sulphide ZnS, when alternating-current voltage/AC voltage is added on two electrodes, electric field makes ZnS particle produce excitation formula transition, thereby at each, charge and discharge in circulation luminously, when it contains different activator, can send the light of different colours.The brightness of EL changes with the change of interelectrode voltage, frequency, generally with the also corresponding increase of increase brightness of voltage and frequency.
Current common EL drive IC on the market, cannot drive large-area EL cold light film.Can only adopt self-oscillatory voltage transformer to drive, but the EL electroluminescent lamp driver of this class based on voltage transformer have many shortcomings: bulky, heavy, noise is large and very large to the dependence of load.The present invention adopts inductance bridge-type push-pull driver to have extremely low electromagnetic interference EMI, thoroughly solves noise and be easy to control, and can fully meet and drive large-area EL cold light film.
Telltale of the present invention adopts the 4th generation LED high-performance solid light source, due to need not the warm start time, bright light fast response time (nanosecond, than filament lamp fast 0.2 second), the pre-warning time winning so just became 0.5～0.7 second from 0.3～0.5 second, if employing flashing lamp, research shows, uses blinking light to compare with traditional braking lamp, driver's reaction can be shortened 0.2 second, can win the pre-warning time about 1 second like this, LED low energy consumption in addition, can electric energy conversion, be directly luminous energy, environmental protection and energy saving are respond well, and filament bulb can only be converted into luminous energy the 12%-18% of electric energy, high light intensity, stability is high, antidetonation is strong, extra long life (100,000 hours, with the same life-span of automobile), light quality is high, essentially no radiation, belong to " green " light source, light beam is concentrated, be easier to control, and do not need to use parasite optically focused, be conducive to reduce the degree of depth of light fixture, color variety is many, red, yellow, blue, green, white, expression-form variation, luminance purity is high, without lampshade, filter, optical wavelength error is in 10 nanometers, consumption of current is low, while reaching the equal luminosity of conventional bulb, consumption of current is only 6% of conventional bulb, power saving fuel-economizing.Luminous heat is very little, and it is not very high that the resistance to effect of heat of light fixture material is required.
According to automobile sport, learn principle, the dynamic and static state parameter of vehicle can carry out expression-form by the acceleration parameter of vehicle,
Wherein V is speed meter per second; A is that acceleration/accel meter per second 2 relation between them represents with following formula:
The acceleration/accel of vehicle can be measured by acceleration pick-up.By the measurement of changes in vehicle speed amount (acceleration/accel), according to the size and Orientation of acceleration/accel, can differentiate vehicle collision, emergency brake, slow brake, anxious deceleration, generally slows down, at the uniform velocity, the various states such as acceleration, because these states are all corresponding one by one with acceleration magnitude and the direction of certain limit.Principle of work of the present invention that Here it is.
Microelectromechanical systems Micro Electro-Mechanical Systems, MEMS refers to can batch making, collection micro mechanism, microsensor, miniature actr and signal are processed, and control circuit, interface, communication and power supply etc. are in micro-module or the system of one.MEMS is the development new branch of science that get up, multidisciplinary intersection along with semi-conductor integrated circuit Micrometer-Nanometer Processing Technology and ultraprecise Machining Technology, it take microelectronics and Machining Technology is support, and scope relates to various engineering technology and the subjects such as microelectronics, mechanics, mechanics, autonetics, material science.Be characterized in: 1, micro-miniaturisation: volume is little, lightweight, it is low to consume energy, inertia is little, resonant frequency is high, response time is short.2, currently take silicon as main material, mechanical electric apparatus function admirable.3, integrated: a plurality of sensors or the actr of difference in functionality, different sensitive direction or braking direction can be integrated in one.4, multidisciplinary intersection: micro-system relates to electronics, machinery, material, manufacture, information and control automatically, physics, chemistry and the multiple subject such as biological, and intensive small and many most advanced and sophisticated achievement that microscopic fields develops in current science and technology.
MEMS micro-acceleration gauge have the unexistent volume of general acceleration pick-up small, lightweight, consume energy low, inertia is little, resonant frequency is high, response time is short, vibration resistance is strong, performance and the nominal price of working stability, the high excellence of reliability.Adopt this bottleneck of MEMS technological breakthrough, MEMS micro-acceleration gauge can be produced in enormous quantities as making integrated circuit, and product qualified rate is very high, has greatly reduced productive costs.MEMS micro-acceleration gauge meets car gage, can be used as the standardised generic electronics package of large-scale industrial production.Use MEMS micro-acceleration gauge to measure deceleration/decel, do not need to be connected with any mechanical part function of vehicle, do not destroy original structure and the function of vehicle.This is the major cause that the present invention selects MEMS micro-acceleration gauge.
If radar ranging is to provide the safety traffic distance on space, the present invention is to provide so temporal " safety traffic distance ", theoretically, two identical vehicles travel with identical speed, if can accomplish to brake simultaneously, even at a distance of 10 centimeters, also can not knock into the back.Analyze vehicle brake process, step on the accelerator is with same pin with touching on the brake, and steps down at ordinary times on throttle, runs into dangerous situation, and pin is moved on brake pedal, and this course of action needs about 0.5 second.When running at high speed, front truck is because of accident sudden stop, and rear car sees that the signal taller speed of braking travels about 0.5 second, could stop.Forward and backward vehicle brake is asynchronous, exists the time difference, the true cause that Here it is knocks into the back.Chaufeur by instinct, before emergency brake, necessarily has one rapidly pin to be moved to the action brake pedal from Das Gaspedal.This action reduces suddenly throttle, and car speed is die-offed, and because the time of this action is very short, so the rate of change of speed is larger, namely negative acceleration is larger.This action is referred to as ' anxious deceleration ', it is the tendency of emergency brake, use it as the early warning signal of emergency brake, just can send out ' preparation-race ' password as the match of running, emergency brake signal is used and ' prepared-brake ' two signal and replace, unexpected emergency brake is converted into the brake of early warning.Figure 19 is the design sketch of mounting vehicle dynamic display device.' preparation password ' signal, can carry out synchronous brake preparation by the forward and backward vehicle of prior notice.Require chaufeur to see ' preparation password ' signal (flashes yellow light), must immediately pin be moved on to brake pedal from Das Gaspedal, carry out the pedal that touches on the brake and prepare.Because it is all a harmful information for front vehicle that the urgency of any reason of front vehicles is slowed down, slow down always right thereupon, once there is ' brake password ' signal (flash red light), front vehicle chaufeur just almost can be stepped on brake in the very first time and front vehicles chaufeur simultaneously; Add and adopt LED light source to shift to an earlier date 0.2 second than filament lamp, for the pre-warning time of 1 second is nearly won in emergency brake, by 80～100 kilometers of speed per hours, be equivalent to increase safety distance more than 20 meters altogether, according to same mechanism, ' preparation password ' can quick copy, delivers in relays backward, utilizes the leading transmission effects of this password, so a car is in danger, all cars of following thereafter all can with front truck synchronous brake, therefore can effectively avoid knocking into the back, particularly the chain of rings knocks into the back.The present invention that Here it is, by vehicle brake synchronization time difference before and after reducing, solves the method knocking into the back.
There is the deceleration that any reason causes in vehicle, as reduce throttle, touch on the brake, the reason such as upward slope, breakdown of machinery, capital rearward presents amber light, Accident Symptom is sent to ' amber light is alert ' signal, watching out for chaufeur checks erroneous ideas at the outset, get ready, have standby could, without suffering from, traffic accident elimination in bud.
The collision of vehicle, emergency brake, slow brake, anxious deceleration, general deceleration, at the uniform velocity, acceleration mode, consideration in view of cost and complexity, generally above-mentioned state is not completely shown, but select 3～5 states to show, such as selecting slow down-general deceleration-acceleration mode of emergency brake-urgency; Or emergency brake-anxious deceleration-acceleration mode; Or emergency brake-slow brake-anxious deceleration-acceleration mode; Or collision-emergency brake-slow brake-combinations such as anxious deceleration-acceleration mode.
Characteristic Design of the present invention:
It is to be some intervals based on acceleration value corresponding to any one status signal that the present invention adopts window comparator to gather acceleration information, rather than a point; Can expand Applicable scope in addition.
It is to be a twinkling signal based on acceleration signal as state maintenance/latch that the present invention adopts single-shot trigger circuit that can repeated trigger type, if do not keep/latch disappearing, cannot carry out signal processing.Employing can repeated trigger type monostable trigger, be because state may have a plurality of acceleration signals corresponding situation with it, with common univibrator, just may produce a plurality of pulses, and with can substantially only producing a pulse by repeated trigger type.Meeting a kind of state shows by a kind of mode; Single-shot trigger circuit tape erasure port that in addition can repeated trigger type, is easy to form priority control circuit.
It is to be twinkling signal based on acceleration signal that the present invention adopts priority control technique of display, be shown to people and see, must expand, and such as expanding to the display of 2～3 seconds, and at the displaying time of 2～3 seconds, tends to occur situation below:
1. current status signal is more urgent than previous, does is danger to continue to show previous state? still show current state? after prior art has shown previously, show again current, so just cause promptly, the hysteresis of danger signal shows, causes traffic accident.As brake signal is lagged behind and has been shown.The 3rd stoplight stop lamp such as France, because use same lamp, produce ' normally ' brake (when red) and two kinds of signals of ' brake suddenly ' (flicker red light 5 seconds), ' normally ' brake formerly, the demonstration of often impact ' brake suddenly ' emergency risks signal, cause hysteresis, this problem has ubiquity.
2. previous status signal is more urgent than current, does is danger to continue to show previous state? still show current state? if it is previous not right to wash out with current going simply yet.
We adopt priority control technique of display (apparatus and method), have solved better above-mentioned conflict, principle be conflict both sides who is more urgent, whom danger, just preferentially shows.
Beneficial effect
1. transmit in advance warning function: solved ' emergency brake early warning ' century-old world-famous puzzle, can send out ' preparation-race ' password as the match of running, send in advance ' preparation-brake ' challenge signal that makes forward and backward vehicle synchronous brake, chaufeur is received ' preparation password ', must immediately pin be moved on to brake pedal from Das Gaspedal, carry out the pedal that touches on the brake and prepare, realize ' precautions averts perils '.Once occur ' brake password ', brake just almost can be stepped in the very first time and front vehicles chaufeur with car vehicle driver in rear simultaneously; Add and adopt LED light source to shift to an earlier date 0.2 second than filament lamp, altogether for 1 second pre-warning time is won in emergency brake nearly, by 80～100 kilometers of speed per hours, be equivalent to increase safety distance more than 20 meters, utilize the leading transmission effects of this password, one car in danger thereafter all with car all can with front truck synchronous brake, therefore can effectively avoid the chain of rings to knock into the back.According to the research report of US Department of Transportation, as more dangerous than Zao 0.5 second now precognition in chaufeur, just can reduce rear-end collision 50%, reduce head-on crash 30%; As precognition danger in early 1 second, just can avoid 90% traffic accident.Referring to Figure 19 design sketch.
2. slow down and report to the police, the function of checking erroneous ideas at the outset: omnidistance supervision, Dynamic continuous display overall process, not only there is abrupt information, and there is a progressive formation, front truck deceleration is danger signal for vehicle following closely, is the omen having an accident, no matter the deceleration what reason causes, as long as reach or surpass and set limit, general deceleration yellow light, anxious deceleration reported to the police with yellow blinking light, and sodium yellow visbility is high, large greasy weather particularly, flash of light more can cause to the other side vigilance, prevents trouble before it happens, and precautions averts perils.
3. wigwag is the language of automobile.Hommization, ' stop-green light of red light capable-flashing light urgency-amber light alert ' signals of vehicles languageization memory rule that what's frequently heard can be repeated in detail, adopting red, yellow, and green is the general color in field of traffic, creative red circle, yellow triangle, the green square of adopting represents respectively and forbids, warns and let pass, both can express CF variation effect, match to the signalling apparatus color of the visual difference ，You Yu traffic control of people department.Can better by people, " be understood ", play reminding effect, take in time to evade accordingly, thereby make driving environment more harmonious, travel safer.
4. people-oriented, adopt red-Huang-green three-color LED or EL to show that vehicle-state changes, having to open has relaxation, can loosen eyeball, eliminates chaufeur nervous psychology and alleviates mental fatigue, by operatorless device, in time, accurately detect and forecast accident potential-deceleration, circular vehicle-state, accomplishes to communicate with each other, know yourself as well as the enemy, have a good idea of how things stand for the vehicle in travelling, and easily drives, alleviated widely labour intensity, physically and mentally healthy and safety have been benefited; Unique brake shows, can collect one's thoughts, step up vigilance, and the generation of effectively preventing accident.
5. by LED or EL color monitor, produce the obvious visual effect of difference, overcome with front blinker single, poor visual effect, particularly brake signal is ambiguous, is difficult to recognize the old problem of slow brake, sudden stop or even collision.Adopt preceence circuit, guarantee that emergency risks signal priority shows.
6. without hindrance installation.Self contained system and vehicle are not theed least concerned, be convenient to all new, old vehicle is supporting, installs very conveniently, need not connect up, only need fixing connecting with the mains onboard just can work, and have self-checking function.
