Embodiment
This device adopts solar panel 7 to charge for accumulator 9 by charge controller 8, and power supply provides again to magnetic and follows closely in the circuit of sensor and warning sign sound, light display part.At the Dangerous Area of blind area front and back ends magnetic nail sensor 2,3 is installed, midblock is provided with warning sign 1, receiving antenna 4 receives the signal that radio transmitter sent by magnetic nail sensor, and be potential pulse with signal transition, the control circuit of input sound, light display part makes LED luminotron 11 and loudspeaker 12 on the warning sign 1 send caution.In addition, the two-way pulse voltage also transmits for the emission of radio frequency signals device provides, and sends the radiofrequency signal of two kinds of different frequencies, carries out subsequent treatment through receiving end, can be the related data that intelligent transportation system provides this highway section.
Referring to Fig. 4, when vehicle 5 or 6 passes through, wheel is through front and back ends magnetic nail sensor 2,3, and electromagnetic induction provides a pulse piezoelectricity, carries out elementary amplification by triode T1 and resistance R 1, adopting C1 and D1 that clutter is considered then removes, the effective impulse signal transfers to T2, carries out secondary and amplifies, after T3 finishes last power amplification, after the RLC oscillatory circuit becomes specific radiofrequency signal with the pulse signal modulation of vehicle process, emit.
Referring to Fig. 3, radiofrequency signal receives the radiofrequency signal that meets setpoint frequency through inductive coil L, and D1 subtracts ripple by diode, by T1 signal is carried out elementary amplification, subtract ripple once more, become dc pulse signal by D2, carry out filtering with C1, become direct current signal.This direct current signal is opened electronic switch T3, and a voltage is exported in the T3 conducting, inputs to input end a or b end (see figure 2) in the road meeting caution control circuit respectively.When having only a car by the highway section, explosive area, produce a Pulse Electric kinetic potential, triode VT1 bias voltage improves, triode VT1 conducting, timing relay J1 energising, normally opened contact 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
1Or C
2After the normally opened contact switch of timing relay 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 5 or 6 to occur,, produce a Pulse Electric kinetic potential through magnetic nail sensor 2 or 3, triode VT2 bias voltage improves, triode VT2 conducting, timing relay J2 energising, the closing of contact of J2, 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 travels with safe speed, when two cars were met, J1 or J2 had spent the time-delay stage, and audible-visual annunciator disconnects, can safe meeting, and can reduce the power consumption of this device.1. warning sign, 2. magnetic nail sensor, 3. magnetic nail sensor, 4. receiving antenna, 5. vehicle, 6. vehicle, 7. solar panel, 8. charge controller, 9. accumulator, 10. green light, 11.LED luminotron, 12. loudspeaker, 13. strobes, 14. emission of radio frequency signals devices.
On the other hand, the output of pulse voltage also is connected with emission of radio frequency signals device 14, makes it send radiofrequency signal, and pulse voltage disappearance radiofrequency signal also disappears.The frequency configuration of two kinds of radiofrequency signals becomes different, 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 quantity of paired pulses is analyzed, the quantity in left lateral track and right lateral track vehicle on the road can be known respectively, the vehicle number that vehicle is in zone of alarm can be obtained to analyzing the interval time of different frequency pulse each.Like this, this simple device can detect the speed of wagon flow and the quantity that enters the zone of alarm vehicle, for intelligent transportation system provides related data.
