Abstract
The invention relates to a vehicle crossing caution board on a road, which belongs to a traffic safety facility, in particular a caution device arranged in a vehicle crossing blind area on the road, which is applied to the technical field of traffic control. The vehicle crossing caution board has the structure that sensors are arranged at two ends of a blind-area road section with the line of sight for vehicle crossing being shielded; the middle of the road section is provided with the caution board on which an electrically-driven sound and light alarm is arranged; and the sensors are connected to the sound and light alarm through a signal line and a corresponding signal amplifying and electronic switch circuit. The invention can generate sound and light caution, can well solve the problem of traffic accident of the vehicle crossing blind-area road section and has simple structure, energy saving and lower cost.
Description
Technical field
The present invention relates to a kind of traffic safety facilities, particularly be arranged on the alarming device of vehicle meeting blind area on the road, belong to technical field of traffic control.
Background technology
Under the situation of bad visibility, correct car usually can cause traffic hazard, and is particularly all the more so at Dangerous Area.Correct car or on the road that obstructed the view by sloping body of the two correct cars that go up a slope, is that the black spot takes place on the hill path, sharp turn that has massif to obstruct the view.For the safety practice in above-mentioned highway section, only be that common notice board or catoptron are installed at present, because this class facility is not eye-catching, regular meeting was ignored when the driver was tired a little, and traffic hazard is also just still occurred frequently.Therefore be necessary to be provided with vision and the sense of hearing are all had warning sign than strong stimulation, just can avoid contingent traffic accident in the highway section.
Summary of the invention
Technical matters to be solved by this invention provides a kind of vehicle crossing caution board on road, the prompting of energy generation sound, light, and simple in structure, energy savings, cost is lower.
Solving the scheme that technical matters of the present invention adopts is: at the two ends, highway section, blind area that the meeting sight line is blocked sensor is set, this midblock be provided with warning sign and on electricity be housed drive audible-visual annunciator, sensor amplifies and electronic switching circuit is connected to audible-visual annunciator through the signal of correspondence by signal wire.
The described sensor that the two ends, highway section are provided with adopts ground induction coil, be equipped with on warning sign that solar panel to the circuit supply of whole device holds, battery and charging control circuit, audible-visual annunciator is loudspeaker and a LED luminotron in parallel, and the strobe of having connected on the LED luminotron.
Above-mentioned signal amplifies and electronic switching circuit adopts triode and timing relay to connect into, the relay of this connection ground induction coil amplifying signal has double-contact, each corresponding series connection one green light of a contact wherein, and connect with the relay of guide sound light crossing-signal in an other contact of this two relay, connects with loudspeaker and LED luminotron again in the contact of the relay of guide sound light crossing-signal.
The green light circuit two ends of being connected in described each timing relay contact also in parallel charging capacitor.
The present invention has utilized electromagnetic induction principle, in advance to being in vision blind area enemy, in time gives more provocative acousto-optic warning, makes both sides driver make anticipation, avoids bumping against with correct car.If have correct car to exist, and in risk range, warning sign begins to send alarm signal.Warning sign adopts the LED LED flash, and vehicle is warned.If outside risk range, the green light flicker is arranged.Warning sign adopts solar panel power supply, dispense with outer connecting power.
The invention has the beneficial effects as follows: having overcome existing road blind area warning sign does not have the send a car shortcoming of prompt facility of blind area, vehicle for hypervelocity carries out the hommization prompting, and the acousto-optic warning that provides has stronger stimulus to the sense organ effect, and therefore the effect that avoids traffic accident improves greatly.This warning sign dispense with outer connecting power adopts the solar panel power supply, LED lumination of light emitting diode, energy savings.

Among Fig. 1-2: 1. warning sign, 2. ground induction coil, 3. signal wire, 4. ground induction coil, 5. signal wire, 6. vehicle, 7. solar panel, 8. charging control circuit, 9. accumulator,, 10. green light, 11.LED luminotron, 12. loudspeaker, 13. strobes.
Embodiment
The invention will be further described below in conjunction with accompanying drawing 1～2 and embodiment.
The present invention adopts solar panel 7 to power, when sunny and vehicle after a little while, solar panel 7 be that accumulator 9 is powered by charging control circuit 8.
In the highway section, explosive area rear end ground induction coil 2 and front end ground induction coil 4 are installed, midblock is provided with warning sign 1, and the electrically driven (operated) audible-visual annunciator that is produced by solar panel 7 is housed on the warning sign 1.The transducing signal of this ground induction coil is transferred on the control circuit board in the warning sign 1 by signal wire 3 and 5.When having only a car by the highway section, explosive area, vehicle 6 at first through the ground induction coil 2 of rear end, produces an induced electromotive force, and triode VT1 bias voltage improves, triode VT1 conducting, timing relay J1 energising, normally opened contact J1, J2 switch closure.Corresponding safety indication green light 10 is luminous, and fluorescent lifetime is consistent with the timing relay time.In order to make green light 10 fluorescent lifetimes more longer, in green light 10 other capacitor C in parallel
1And C
2, after the normally opened contact switch of J1, J2 disconnects, because capacitor C
1And C
2Charge, discharge needs a period of time, and green light 10 can bright again a period of time.If there is this moment correct vehicle 6 to occur, the ground induction coil 4 through front end produces an induced electromotive force, triode VT2 bias voltage improves, triode VT2 conducting, timing relay J2 energising, the J2 closing of contact, so relay J 2, J1 conducting simultaneously make another be connected on the timing relay J3 energising in J2, the J1 contact, the J3 closing of contact, strobe 13 energisings, make LED luminotron 11 glimmer, loudspeaker 12 pipe simultaneously, provide the caution that there is correct car in the place ahead.If vehicle 6 travels with safe speed, when vehicle was met, J1 or J2 spent the time-delay stage, and audible-visual annunciator disconnects, can safe meeting, and reduce the power consumption of this device.
