Embodiment
The utility model is described in further detail below in conjunction with each drawings and Examples.
This device adopts solar panel 7 and piezoelectric board 2,4 to supply power with double circuit for accumulator 14 by charging panel 17.The structure of piezoelectric board is that the interlayer of adorning between the two boards has a plurality of piezoelectric ceramic piece T, and interlayer is sealed.Behind diode D of each piezoelectric ceramic piece T series connection, capacitor C in parallel is input to charging panel 17 with pulse current, for accumulator charges.Pulse current constitutes signal simultaneously, is input to circuit control panel 15, starts electronic switching circuit, makes mounted LEDs luminotron 8 stroboscopics and the prompting of voice generators 11 sounding on the warning sign 1.In addition, this pulse voltage provides power supply for radio-frequency signal generator 16, sends radiofrequency signal.
Front end piezoelectric board 2 is installed at stop line 9 places, and at installation rear end, the indication wire place of at interval suitable distance piezoelectric board 4, in the electronic switching circuit of two-way piezoelectricity pulse by the circuit control panel 15 of transmission line in the warning sign 1, this electronic switching circuit adopts triode VT1 and VT2 amplifying signal, adopt timing relay J1 and J2 to delay time, the corresponding strobe 10 and the LED luminotron 8 of connecting in the electronic switching circuit path that connect of the pulse signal of the piezoelectric board 4 at indication wire place, the corresponding voice generators 11 that connects in the electronic switching circuit path of the pulse signal of the piezoelectric board 2 at stop line 9 places.
When if bicycle 6 surpasses indication wire, press and press down electroplax 4 and send pulse voltage, through pulse output terminal 5 to triode VT1, make the VT1 bias voltage improve, triode VT1 conducting is for radio-frequency signal generator 16 provides power supply, radiofrequency signal is sent in radio-frequency signal generator work, meanwhile, timing relay J1 energising, the closing of contact that J1 connects with LED luminotron 8, strobe 10 energisings, make and 8 flickers of LED luminotron provide prompting for the first time, the signal ramp to stop.Afterwards, if surpass stop line 9, piezoelectric board 2 sends pulse voltage, through pulse output terminal 3 to triode VT2, the VT2 bias voltage improves, and triode VT2 conducting is for radio-frequency signal generator 16 provides power supply, radiofrequency signal is sent in radio-frequency signal generator work, meanwhile, timing relay J2 energising, the J2 closing of contact, voice generators 11 work provide voice suggestion.At this moment, J1 still is in the time-delay conducting state, and 8 flickers of LED luminotron provide light prompt, and this is prompting for the second time.When red light extinguished, the power supply of circuit control panel 15 disconnected by the linked switch on the red light power lead 13 12 and does not work.
Here, the radio-frequency signal generator 16 that pulse voltage is formed for the LC oscillatory circuit provides power supply, sends radiofrequency signal, and pulse voltage disappearance radiofrequency signal also disappears.Therefore, signal also has pulse characteristic frequently.When bicycle passes through the front and back piezoelectric board, will send radio-frequency (RF) pulse signal, the receiving end at place not far from one another carries out subsequent treatment, enters into computing machine analysis after entering into data acquisition board after the filtering, the quantity of paired pulses is analyzed, and can know the quantity of the vehicle of bicycle lane.This simple device can provide related data for intelligent transportation system.
