EL EL sheet principle
EL sheet places luminescent powder between two plate electrodes and constitutes.It is a sandwich type structure, an electrode is respectively arranged up and down, and the very nesa coating ITO film that powers on, light from then on face penetrate, bottom electrode is a back electrode, its material is mainly silver or carbon, and luminescent material mainly is zinc sulphide ZnS, when alternating-current voltage/AC voltage is added on two electrodes, electric field makes the ZnS particle produce the excitation formula transition, thereby charge and discharge in the circulation luminously at each, 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 speaking with the also corresponding increase of the increase brightness of voltage and frequency.
Current common on the market EL drive IC can't drive large-area EL cold light film.Can only adopt self-oscillatory voltage transformer to drive, but this class have many shortcomings based on the EL electroluminescent lamp driver of voltage transformer: bulky, heavy, noise big and very big to the dependence of load.The utility model adopts inductance bridge-type push-pull driver to have extremely low electromagnetism in disturbing EMI, thoroughly solves noise and is easy to control, can fully satisfy driving large-area EL cold light film.
The utility model telltale adopts the 4th generation LED high-performance solid light source, because need not the warm start time, bright lamp speed of response fast (nanosecond, than filament lamp fast 0.2 second), the pre-warning time that wins so just became 0.5～0.7 second from 0.3～0.5 second, if the employing flashing lamp studies show that, use blinking light to compare with the 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 directly be converted into luminous energy to electric energy, environmental protection and energy saving are respond well, and filament bulb can only be converted into luminous energy to 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 height, essentially no radiation belongs to " green " light source, light beam is concentrated, be easier to control, and do not need to use parasite optically focused, help reducing the degree of depth of light fixture, color variety is many, redness, yellow, blueness, green, white, the expression-form variation, the luminance purity height need not lampshade and filters, and the optical wavelength error is in 10 nanometers, consumption of current is low, when reaching the equal luminosity of conventional bulb, consumption of current only is 6% of a conventional bulb, the 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.
Learn principle according to automobile sport, the dynamic and static state parameter of vehicle can come expression-form with the acceleration parameter of vehicle, and wherein V is the speed meter per second; A is the acceleration/accel meter per second
2Relation between them is represented 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), can differentiate vehicle collision, emergency brake according to the size and Orientation of acceleration/accel, slow brake, the anxious deceleration, the general deceleration, at the uniform velocity, various states such as acceleration are because these states are all corresponding one by one with the acceleration magnitude and the direction of certain limit.Principle of work of the present utility model that Here it is.
Microelectromechanical systems Micro Electro-Mechanical Systems, but MEMS is meant batch making, collection micro mechanism, microsensor, miniature actr and signal conditioning, and control circuit, interface, communication and power supply etc. are in the micro-module or the system of one.MEMS is along with the development of semi-conductor integrated circuit Micrometer-Nanometer Processing Technology and ultraprecise Machining Technology grows up, the new branch of science of multidisciplinary intersection, it is a support with microelectronics and Machining Technology, and scope relates to various engineering technology and subjects such as microelectronics, mechanics, mechanics, autonetics, material science.Be characterized in: 1, micro-miniaturisation: volume is little, in light weight, power consumption is low, inertia is little, resonant frequency is high, response time is short.2, current is main material with silicon, the mechanical electric apparatus function admirable.3, integrated: as can be integrated in one a plurality of sensors or the actr of difference in functionality, different sensitive direction or braking direction.4, multidisciplinary intersection: micro-system relates to multiple subjects such as electronics, machinery, material, manufacturing, information and automatic guidance, physics, chemistry and biology, and the many most advanced and sophisticated achievement of intensive small and microscopic fields development in the current science and technology.
The MEMS micro-acceleration gauge has that the unexistent volume of general acceleration pick-up is small, in light weight, power consumption is low, inertia is little, resonant frequency is high, response time is short, the antivibration ability is strong, the performance and the nominal price of working stability, the high excellence of reliability.Adopt this bottleneck of MEMS technological breakthrough, the 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.The MEMS micro-acceleration gauge meets car gage, can be used as the standardised generic electronics package of large-scale industrial production.Use the MEMS micro-acceleration gauge to measure deceleration/decel, do not need to be connected, do not destroy the original structure and the function of vehicle with any mechanical part function of vehicle.This is the major cause that the utility model is selected the MEMS micro-acceleration gauge.
If radar ranging provides the safety traffic distance on the space, the utility model provides temporal " safety traffic distance " so, theoretically, two identical vehicles travel with identical speed, if can accomplish to brake simultaneously, even, also can not knock into the back at a distance of 10 centimeters.Analyze the vehicle brake process, step on the accelerator is with same pin with touching on the brake, and steps down at ordinary times on the throttle, runs into dangerous situation, and pin is moved on the brake pedal, and this course of action needs about 0.5 second.When running at high speed, front truck is because of the accident sudden stop, and back 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 before emergency brake, necessarily has one rapidly pin to be moved to action on the brake pedal from Das Gaspedal by instinct.This action makes throttle reduce suddenly, and car speed is die-offed, because the time of this action is very short, so the rate of change of speed is bigger, just negative acceleration is bigger.This action is referred to as ' the anxious deceleration ', it is the tendency of emergency brake, with its early warning signal as emergency brake, just can send out ' preparation-race ' password as the match of running, the emergency brake signal is replaced with ' preparation-brake ' two signals, 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 be carried out the synchronous brake preparation by the forward and backward vehicle of prior notice.Require chaufeur to see ' preparation password ' signal (flashes yellow light), must move on to pin on the brake pedal from Das Gaspedal immediately, carry out the pedal that touches on the brake and prepare.Because anxious the deceleration for front vehicle of any reason of front vehicles all is a harmful information, to slow down always right thereupon, in case ' brake password ' signal (flash red light) occurs, the 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, win 1 second pre-warning time nearly for emergency brake altogether,, be equivalent to increase safety distance more than 20 meters by 80～100 kilometers of speed per hours, according to same mechanism, ' preparation password ' but quick copy deliver in relays backward, utilize the leading transmission effects of this password, so a car is in danger, all cars of following thereafter all can with the front truck synchronous brake, so can effectively avoid knocking into the back, particularly the chain of rings knocks into the back.Here it is the utility model solves the method that knocks into the back by vehicle brake synchronization time difference before and after reducing.
The deceleration that any reason causes appears in vehicle, as reduce throttle, touch on the brake, reason such as upward slope, breakdown of machinery, the capital rearward presents amber light, the accident symptom of a trend is sent ' amber light is alert ' signal, watching out for chaufeur checks erroneous ideas at the outset, get ready, have fully and could not have trouble, traffic accident is eliminated in bud.
The collision of vehicle, emergency brake, slow brake, the anxious deceleration, the general deceleration, at the uniform velocity, acceleration mode is in view of the consideration of cost and complexity, generally above-mentioned state is not completely shown, but select 3～5 states to show, such as selecting emergency brake-urgency to slow down-general deceleration-acceleration mode; Perhaps emergency brake-urgency deceleration-acceleration mode; Perhaps emergency brake-slow brake-urgency deceleration-acceleration mode; Perhaps collision-emergency brake-combinations such as slow brake-urgency deceleration-acceleration mode.
The design of the utility model characteristic:
It is some intervals that the utility model adopts window comparator collection acceleration information to be based on the cooresponding acceleration value of any one status signal, rather than a point; Can enlarge Applicable scope in addition.
It is a twinkling signal that but the utility model adopts the single-shot trigger circuit of repeated trigger type to be based on acceleration signal as state maintenance/latch, if do not keep/latch and will disappear, can't carry out signal conditioning.But adopting the monostable of repeated trigger type to trigger, is because a state has the cooresponding with it situation of a plurality of acceleration signals, with common univibrator, just may produce a plurality of pulses, but and only produce a pulse basically with the repeated trigger type.Meeting a kind of state shows with a kind of mode; But the single-shot trigger circuit tape erasure port of repeated trigger type is easy to constitute the preceence control circuit in addition.
It is twinkling signal that the utility model adopts preceence control technique of display to be based on acceleration signal, be shown to the people and see, must expand, and such as the shows signal that expands to 2～3 seconds, and 2～3 seconds demonstration time, tends to occur following situation:
1. current status signal is more urgent than previous, is danger to continue to show previous state? still show current state? prior art shown previous after, show current again, so just cause promptly, the hysteresis of danger signal shows, causes traffic accident.As being lagged behind, brake signal shown.The 3rd stoplight stop lamp such as France, because use same lamp, produce ' normally ' brake (red light is bright) and two kinds of signals of ' brake suddenly ' (flicker red light 5 seconds), ' normally ' brake formerly, the demonstration of often influence ' brake suddenly ' emergency risks signal, cause hysteresis, this problem has ubiquity.
2. previous status signal is more urgent than current, 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 preceence control technique of display (apparatus and method), have solved above-mentioned conflict better, principle be the conflict both sides who is more urgent, whom danger just preferentially shows.
Beneficial effect
1. transmit warning function in advance: solved ' emergency brake early warning ' century-old world-famous puzzle, can send out ' preparation-race ' password as the match of running, send ' preparation-brake ' challenge signal that makes forward and backward vehicle synchronous brake in advance, chaufeur is received ' preparation password ', must move on to pin on the brake pedal from Das Gaspedal immediately, carry out the pedal that touches on the brake and prepare, realize ' precautions averts perils '.In case occur ' brake password ', brake just almost can be stepped in the very first time and front vehicles chaufeur simultaneously with the car vehicle driver in the rear; Add and adopt led light source to shift to an earlier date 0.2 second than filament lamp, win 1 second pre-warning time nearly for emergency brake altogether, 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 the front truck synchronous brake, so can effectively avoid the chain of rings to knock into the back.According to the research report of US Department of Transportation, more dangerous as chaufeur than Zao 0.5 second now precognition, just can reduce rear-end collision 50%, reduce head-on crash 30%; Dangerous as early 1 second precognition, 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, the Dynamic continuous display overall process, sudden change information is not only arranged, and progressive formation arranged, the front truck deceleration is a danger signal for vehicle following closely, is the omen that has an accident, no matter the deceleration what reason causes, as long as reach or surpass and set limit, the general deceleration used yellow light, and anxious the deceleration reported to the police sodium yellow visbility height with yellow blinking light, the particularly big greasy weather, flash of light more can cause to the other side vigilance, prevents being loyal to possible trouble, and precautions averts perils.
3. wigwag is the language of automobile.Hommization, ' red light stops-green light is capable-flashing light urgency-amber light is alert ' signals of vehicles language memory rule that what's frequently heard can be repeated in detail, adopting red, yellow, green is the interior general color of field of traffic, creative red circle, yellow triangle, the green square of adopting represented respectively and forbidden, warns and let pass, both can express the CF variation effect, give the visual difference of people, the signalling apparatus color with traffic control department matches again.Can better " be understood " by the people, play reminding effect, in time take to evade accordingly, thereby make driving environment more harmonious, it is safer to travel.
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 the chaufeur nervous psychology and alleviates mental fatigue, in time, accurately detect and forecast accident potential-deceleration by operatorless device, the circular vehicle-state is accomplished 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 labour intensity widely, physically and mentally healthy and safety have been benefited; Unique brake shows, can collect one's thoughts, and steps up vigilance, and the accident that effectively prevents takes place.
5. by LED or EL color monitor, produce the tangible 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 the preceence circuit, guarantee that the emergency risks signal priority shows.
