Description

Intelligent collision avoidance display for automobiles

A kind of intelligent vehicle collision avoidance display device.

The utility model belongs to traffic and shows automatically and the collision avoidance device.

In the urban transportation on the crossroad of Xia shape, herringbone, bend and train and automobile, be difficult to be provided with point duty booth and on duty round the clock everywhere, for reminding the driver to note the vehicle that sight line is outer, reflective mirror is set up in the location that has, the scenery that this reflective mirror reflects is too little, the inclement weather not eye-catching, overcast and rainy, that mist is arranged or night reflective mirror just ineffective; The sign board that intercity long-distance highway, black spot or railway and highway intersection use also often loses usefulness to the vehicle of night running.

The purpose of this utility model is to provide the visibility good, and is not affected by environment, makes the driver can in time understand vehicle dynamic, so that take measures rapidly, and a kind of intelligent collision avoidance display device of avoiding vehicle to have an accident in the intersection.

Another purpose of the present utility model is to replace some traffic mark board that is arranged on trackside and reflective mirrors, realizes the round-the-clock demonstration of unmanned control.

The utility model is to implement like this: by custom-designed alternate certain distance, two identical induction probes of structure (number of turn with around to), be included in and constitute a combined probe in the straight tube-like aluminum shell, being embedded in be about tens meters away from crossing locates, when automobile passes through combined probe, successively in different time in each probe signal induced electricity, this signal amplifies through the operational amplifier open loop, send into the single chip microcomputer automatic information processing, and on display, demonstrate and give the car shape of programming earlier, traffic sign and times such as road shape, and the speed of a motor vehicle and from the distance at crossing, as required the electroacoustic device can also be set, display mainly shows that by pattern and literal required some luminotrons arrangements form, and above-mentioned single chip microcomputer then places the space in the display.

For the ease of understanding, sketching its principle is that necessary (Yi Xia shape crossing is an example), as shown in Figure 1, when vehicle during by the d end of R direction by right probe B, induced signal is delivered to the interruption inlet of single chip microcomputer through processing and amplifying and photoelectric coupled device, export a signal simultaneously and signal is sent into display driver circuit, make road shape and the luminous demonstration of vehicle pattern through photoelectrical coupler.But when vehicle by c end when the d end travels, the c probe at first records signal, through the MICROCOMPUTER PROCESSING and the look-at-me (decided by artificial programming break period) of forbidding the d end, then display device does not show, has solved the directional selectivity of combined probe thus.The vehicle of promptly crossing the crossing can not make display device show once more, comprises from a V left side always or the vehicle of turning right.

Concrete structure of the present utility model is provided in detail by accompanying drawing and embodiment.

Wherein, 1 combined probe, 2 road surfaces, 3 shielded leads, 4 pedestals, 5 displays; 6 iron cores, 7 coils, 8 insulation framework, 9 shells, 10 insulcretes, 11 back doors; 12 single chip microcomputers, 13 light emitting diodes, 14 cover glasses, 15 light shields, 16 decoder drivers, 17 photoelectrical couplers.

The utility model is mainly by the combined probe that is embedded in location, crossing sense vehicle (1), and a single chip microcomputer (12) three parts that are fixed on the display (5) on the pedestal (4) and place are within it formed, shown in Fig. 1,2 and 4.Combined probe A(a of the present utility model and b) or B(c and d) (1) all be to be made of two identical probes of structure (number of turn with around to etc.), each probe (a, b, c or d) all is by the enameled wire in the suitable line footpath coil (7) on the insulation framework (8), and insert the interior iron core (6) of skeleton (8) cavity and form, iron core (6) is made by the soft iron material of high-quality.Probe (a and b or c and d) phase spacing is about one meter, and contain in it with aluminium shell (9) encapsulation on the two sides, considers insulation, the protection against the tide of probe and add fixed bit, charges, solidifies with epoxy resin in the shell (9).Disturb in order to reduce high-frequency electromagnetic, the screen layer of the shielded lead (3) of being drawn by combined probe (1) has good being electrically connected with the metallic aluminium of shell (9).

Combined probe (1) is electrically connected with single chip microcomputer (12) through amplification treatment circuit and photoelectrical coupler (1) by shielded lead (3), this single chip microcomputer (12) adopts 80C31, and with idle mode work, during no vehicle, display device is not worked, only when vehicle press certain orientation by the time, combined probe (1) records behind the signal application and interrupts, this signal makes single chip microcomputer (12) enter duty, and by decoder driver (16) display lighting is shown.Above-mentioned 80C31 single chip microcomputer is a kind of CMOS type product of 51 series monolithics, its expression be connected as Fig. 4, this single-chip microcomputer provides 4 external interrupt inlets, (INTO, INTI, TO, TI), remove INTO, INTI can directly use, and TO, TI then can be set to the external counting state, and with inner counter register (TH ₀, TL ₀And TH ₁TL ₁) preset to " FF ", work as T ₀Or T ₁When having by 1 to 0 saltus step, the value of inner counter register increases by 1, this moment, counter register overflowed, and send look-at-me, single chip microcomputer is handled this look-at-me, and sends corresponding signal by each mouthful of P1.0～P1.2, and this signal is through gate circuit (74LS07), photoelectric coupled device (4N25) and decoder driver make the corresponding pattern light emitting diode bright.Consider power saving, cmos device is all adopted in address latch and program storage, constitutes the microsystem of this device jointly, and it is the address latch device that this device adopts 74HC373, and 27C32 is a memory under program spare.

As the display (5) of Fig. 3 (a) shown in (b); mainly by insulcrete (10) and the last pattern of pressing thereof; literal requires to arrange and fixing some light emitting diodes (13), forms as the transparent protective glass that is placed in the place ahead (14) of protection usefulness and the back door of being convenient to keep in repair (11) at the light shield (15) and the back side.Light shield (15) is to block sun parasitic light with the raising contrast together with casing, and protects the single chip microcomputer (12) in it.Light emitting diode (13) can adopt the mode of many series connection to connect, with minimizing or without current-limiting resistance, cut down the consumption of energy, and be fixed on (10) on the insulcrete with tubular rivet, consider visual contrast and display brightness, light emitting diode (13) should be selected the light collecting luminotron of transparent enclosure for use, and works to flash mode.Consider caution driver and pedestrian again, sound device (not drawing among the figure) also can be set, in display device as loudspeaker.The display device power consumption is less again, is convenient installing, and its power supply also can adopt accumulator.

In sum, the utility model is directly perceived, eye-catching, reliable, power saving, is that the black spot substitutes traffic mark board and reflective mirror, realizes the indispensable means of transportation of the round-the-clock demonstration of unmanned control.
