The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As a kind of embodiment of the present utility model, consult Fig. 1, comprise light intensity detector 1, for detection of the light intensity of the car bulb that goes in the same direction; Ambient light sensor 2, for gathering ambient light; Slope circuit detector 3, the grade angle for detection of automobile when the uphill/downhill; The first electronic switch 4, for controlling the Push And Release of country beam; The second electronic switch 5, is used for controlling the Push And Release of passing light; Micro controller system 6, be electrically connected to respectively light intensity detector 1, ambient light sensor 2, slope circuit detector 3, the control end of the first electronic switch 4 and the control end of the second electronic switch 5, and the variation of the grade angle when the uphill/downhill judges according to the light intensity of ambient light, the car bulb that goes in the same direction or automobile, control the first electronic switch 5 and the second electronic switch 5, realize the switching of Der Scheinwerfer mit FernlichtAbblendlichtStandlicht distance-light.
Light intensity detector 1 comprises opto-electronic pickup 11, and because the switching of distance-light does not need very high response frequency, as long as the enough higher positions of sensitivity can meet the demands, therefore, opto-electronic pickup 11 is optional with photoconductive cell, photoemissive element, photodiode or photo-transistor.What open when the car on opposite is country beam, the electric current that flows through opto-electronic pickup will strengthen, and when electric current surpasses certain value, micro controller system 6 will be controlled the first electronic switch 4 and the second electronic switch 5, realize the switching of Der Scheinwerfer mit FernlichtAbblendlichtStandlicht distance-light, also remind other driver to switch to passing light simultaneously.
Consider the disturbance rejection to the collection of light intensity signal, and the A/D sample quantization that facilitates micro controller system 6, opto-electronic pickup 11 is preferably used photo-transistor.And light intensity detector 1 also comprises dual operational amplifier 12, opto-electronic pickup 11 is electrically connected to dual operational amplifier 12, and 12 pairs of signals of dual operational amplifier are nursed one's health and amplify.The dual operational amplifier 12 is here LM358 single supply Linear Double op amp.
Slope circuit detector 3 comprises slope detection sensor 31, and slope detection sensor 31 comprises housing 311, is placed on the battery acid 312 in housing 311 and is located at the graphite electrode 313 on housing 311.Battery acid 312 is electric good conductors, is in a liquid state at normal temperatures, and slope detection sensor 31 utilizes this double properties of battery acid 312 just, is allowed to condition at the effect that can play conduction while needing in automobile normal running, connects circuit.Graphite electrode 313, is connected with external circuits, and and if only if when battery acid 312 contacts with positive/negative plate simultaneously, and circuit is just switched on.
As Fig. 2, when automobile travels on smooth road surface, slope detection sensor 31 is the state of level, and now the graphite positive/negative plate access failure of slope detection sensor 31, does not have signal to send to micro controller system 6.According to driver's experience, when the gradient surpasses 5 °, if do not change country beam into passing light, can not see Chu's scenery nearby, from visually affecting traffic safety, also make driver produce nervous phychology simultaneously, affect safety traffic.And downward grades inclination angle is while being less than 5 °, driving states and flat road surface difference are little, have not just changed necessity of light.When automobile continues to be more than or equal to the inclination angle up-hill journey of 5 °, slope detection sensor 31 is in state as shown in Figure 3, now the battery acid 312 of slope detection sensor 31 contacts with graphite positive/negative plate simultaneously, form close circuit, signal is sent to micro controller system 6, and micro controller system 6 is controlled the switching of the distance-light of headlight.
Because the Continuity signal of graphite electrode is easily received interference, during as automobile bumpiness, the fluctuation of battery acid 312 can cause the of short duration repeatedly conducting of electrode, for fear of the generation of such situation, slope circuit detector 3 also comprises comparator 32, and slope detection sensor 31 is connected with comparator 32 signals.Comparator 32 is LM393 comparator, and the electric signal that graphite electrode 313 is drawn carries out the conditioning shaping of signal by LM393 comparator, with Transistor-Transistor Logic level output, for micro controller system 6, reads.
In the present embodiment, what micro controller system 6 was selected is ATmega16 micro controller system, and this micro controller system can meet speed of response of the present utility model completely, and safe and reliable, and cost is low.
Der Scheinwerfer mit FernlichtAbblendlichtStandlicht distance-light automatic switching control equipment also comprises siren horn 7, and siren horn 7 is electrically connected to micro controller system 6, controls siren horn 7 and sends prompt tone, to remind navigating mate when micro controller system 6 is controlled the switching of Der Scheinwerfer mit FernlichtAbblendlichtStandlicht distance-light.
Using micro controller system 6 as data processing and control unit, with light intensity detector 1, detect the light intensity of the car bulb that goes in the same direction or according to slope circuit detector 3, detecting the grade angle of automobiles when the uphill/downhill changes, when chaufeur is during at meeting or uphill/downhill, the car bulb going in the same direction impinges upon on the opto-electronic pickup 11 of light intensity detector 1, and opto-electronic pickup 11 sends to micro controller system 6 through dual operational amplifier 12 amplifying signals by A/D conversion; Or when broken circuit detector 3 detect the variation of grade angle, and convert Transistor-Transistor Logic level output to and give micro controller system 6, when reaching the condition of the predefined automatic unlatching long-and-short distant light of micro controller system 6, the distance-light that automatically completes Der Scheinwerfer mit FernlichtAbblendlichtStandlicht switches.
Above-mentioned explanation to the disclosed embodiments, makes professional and technical personnel in the field can realize or use the utility model.To the multiple modification of these embodiment, will be apparent for those skilled in the art, the in the situation that General Principle as defined herein can be within not departing from spirit or scope of the present utility model, realize in other embodiments.Therefore, the utility model will can not be limited to these embodiment shown in this article, but will accord with principle disclosed herein and features of novelty the widest consistent scope.
