Description
Technical field
The utility model relates to a kind of warning sign of No Honking, and particularly the label of automatically vehicle ring loudspeaker being warned belongs to technical field of traffic control.
Background technology
A lot of locations in the city in order to guarantee civic work, study and rest environment, require all that no horn, and what generally adopt at present is the label of fixed image.Though this label can play certain suggesting effect, effect is relatively poor, because present road conditions becomes increasingly complex, driver's more attention is to be placed on the vehicle and crowd that constantly shuttles back and forth, and seldom can note the horn-blowing control warning sign in roadside; Blocking up of Sheng Huo fast pace and road caused the anxiety on the driver psychology easily in addition, also is easy to ignore the horn-blowing control sign.Therefore, be necessary more effectively in time to point out, avoid the driver loudspeaker agitations citizen of ringing.
Summary of the invention
Technical problem to be solved in the utility model provides the automatic warning sign of a kind of sun power piezoelectricity No Honking, it is simple in structure, easier arousing attention, the horn-blowing control prompting is more humane, adopt solar panel and piezoelectric board to supply power with double circuit, dispense with outer connecting power is saved the energy, and can be provided related data for intelligent transportation system.
Solving the scheme that technical matters of the present utility model adopts is: the front end in the horn-blowing control highway section is laid piezoelectric board and warning sign, piezoelectric board pulse output and solar panel are exported by charging panel charge in batteries, the current return of green light prompting and LED strobe warning is housed respectively on the warning sign, piezoelectric board pulse output is as the startup input signal of green light prompting current return, and the audio frequency piezoelectric patches is as the startup input signal of LED strobe warning current return.
The structure of described piezoelectric board is between the interlayer of two boards a series of piezoelectric ceramic pieces to be housed, the sealing of interlayer edge, and behind diode of each piezoelectric ceramic piece series connection, electric capacity in parallel, pulse current is input to charging panel; Green light prompting current return adopts the triode triggering and conducting, is connected with the electric capacity of time-lag action at transistor base; LED strobe warning current return adopts the triode triggering and conducting, and transistor emitter is connected with the timing relay of time-lag action.
The current return luminescent device of described LED strobe warning adopts LED luminotron and strobe to be in series; Piezoelectric board pulse output also is input to the signal end of radio-frequency signal generator.
Described radio-frequency signal generator is the LC oscillatory circuit of band emitting antenna.
The beneficial effects of the utility model are: changed the stiff prompting effect of existing warning sign, carried out the hommization prompting for the vehicle of honking; This warning sign dispense with outer connecting power adopts solar panel and piezoelectric board dual power supply, and the LED lumination of light emitting diode has been saved the energy, and has guaranteed overcast and rainyly also can work; Utilize the showy light of LED light emitting diode to combine, can cause that more the driver notes, also make traffic administration personnel's management lighter with continuous flicker; The piezoelectricity pulse outputs to radio-frequency signal generator, helps computer acquisition and enters horn-blowing control highway section signals of vehicles, can be intelligent transportation system related data is provided.
Description of drawings
Fig. 1 is circuit theory diagrams of the present utility model;
Fig. 2 looks synoptic diagram for the utility model master.
Each label is represented successively in Fig. 1～2: warning sign 1, transmission line 2, solar panel 3, piezoelectric board 4, vehicle 5, LED luminotron 6, green warning light 7, audio frequency piezoelectric patches 8, charging panel 9, accumulator 10, strobe 11, radio-frequency signal generator 12, green light prompting current return 13, LED strobe warning current return 14.
Embodiment
Referring to Fig. 1,2, adopt solar panel 3 and piezoelectric board 4 to supply power with double circuit for accumulator 10 by charging panel 9.The structure of piezoelectric board 4 is between the interlayer of two boards piezoelectric ceramics to be housed, and interlayer is sealed again.Behind diode D of each piezoelectric ceramic piece series connection, capacitor C in parallel
0Pulse current constitutes signal simultaneously, be input to green light prompting current return 13 on the warning sign 1, as starting input signal, in addition, this pulse voltage also provides power supply and signal for radio-frequency signal generator 12, send radiofrequency signal, carry out subsequent treatment, enter into computing machine after sending into data acquisition board by receiver.
As vehicle 5 during by highway section, horn-blowing control district, vehicle 5 at first passes through piezoelectric board 4, produce a piezoelectricity pulse voltage, triode VT2 bias voltage improves, and triode VT2 conducting is charged to capacitor C after the triode VT2 conducting, the current potential of capacitor C improves, compound transistor VT3 conducting, the green warning light 7 in the green light prompting current return 13 is luminous, gives driver's hommization prompting.Vehicle 5 is through behind the piezoelectric board 4, and piezoelectric board 4 induced signals disappear, and prime triode VT2 closes, but because capacitor C is charged, and discharge needs a period of time, the compound transistor VT3 of back level also can delay time conducting a period of time, and green warning light 7 also continues to light.If this car ring this moment loudspeaker, the audio frequency piezoelectric patches in the LED strobe warning current return 14 8 can produce an induced electromotive force so, and the bias voltage of triode VT1 improves, triode VT1 conducting, timing relay J energising, the contact switch closure of J.Strobe 11 energisings make 6 flickers of LED luminotron to provide very dazzling No Honking caution.
In addition, in the time of piezoelectric board 4 piezoelectricity pulses, for radio-frequency signal generator 12 provides power supply (for example can adopt simple LC oscillatory circuit), send radiofrequency signal, pulse voltage disappearance radiofrequency signal also disappears, and therefore, radiofrequency signal also has pulse characteristic.When vehicle passes through piezoelectric board, will send radio-frequency (RF) pulse signal, the receiving end at place not far from one another carries out subsequent treatment, enter into computing machine analysis after entering into data acquisition board after the filtering, the number of pulses quantitative analysis, can know the quantity that enters horn-blowing control highway section vehicle, this simple device can provide related data for intelligent transportation system.
