Below in conjunction with accompanying drawing the present invention is further described:
In the vehicle shelter electronics package B is set, it is formed by transmitting and receiving two parts, and radiating portion is made of encode circuit (in advance set of number being solidificated on the integrated circuit) and modulate emission output circuit, flush type switch (warning sensor).Receiving unit is made up of frequency conversion frequency discrimination, digital decoding, several parts of electronic switch.Transmit and receive the shared same antenna, concrete working process is, when cartheft enters operator's compartment, when touching flush type switch K, electronics package B circuit is connected, by encode circuit the set of number that solidifies is exported, deliver to modulation transmitter (the receiving unit frequency conversion of this embodiment, frequency discrimination, amplitude limit, output circuit is finished by an integrated circuit TK304R), modulation transmitter is finished by the TK304 integrated package, launch the FM signal that contains this car feature, and signal delivered to receiving end simultaneously, through frequency conversion, frequency discrimination, decode last electronic switch action with the oil circuit on the car, circuitry cuts.The similar wireless interspeaker of electronics package C profile that chaufeur is carried, just the antenna polygamy directional antenna, after chaufeur leaves vehicle, can rely on this device to know situation on the car.The electronics package of carrying is provided with to be sought to button, tin tone keys, lock car button, intercom push key.After chaufeur is pressed the micro controller system of seeking in this device of button and is received instruction, send the set of number signal, deliver to modulation transmitter and send a pulsed frequencymodulated signal via antenna, this signal is received by shelter electronics package A on the car, via the antenna frequency conversion, frequency discrimination, micro controller system identification assert it is to seek behind signal, micro controller system is exported the good digital signal of one group of pre-edit to modulation transmitter, connect the power supply of transmission circuit simultaneously, send a pulse-frequency modulation ripple, the electronics package that chaufeur is carried is received echo, through the antenna frequency conversion, amplify demodulation to the field intensity display circuit, the field intensity value of echo is shown, horizontally rotate the electronics package carried 360 degree, just can know which side to electric field stronger slightly than the electric field of other direction, this direction is exactly the place direction of car.Adopt short pulse mode of operation intermittently when electronics package on the car and the electronics package of carrying interrelate, can save electric energy, the length of pulse can be provided with arbitrarily by the soft program of prior establishment.When seeing peak value from the field intensity display circuit, from audio output circuit output pulse sound, both cross-references can be got rid of mistake and receive to know and declare, and improve reliable giving birth to and make vehicle directional more accurate.Chaufeur is pressed and is listened key, carry electronics package C and send the frequency modulation on pulse that has this meaning, the electronics package A in shelter in the car, micro controller system Dou microphone circuit after receiving identification, modulation transmitter is open-minded, at this moment after the sound on the car is picked up by microphone, deliver to modulation transmitter, launch with frequency-modulated wave through amplification.The electronics package C that carries receives signal, and is after frequency conversion, frequency discrimination, micro controller system identification are handled that audio output circuit is open-minded, just heard the sound on the car.If chaufeur is pressed locking key, the electronics package C that carries sends the electronics package A in shelter in the frequency modulation on pulse car that has this meaning, micro controller system output set of number is transformed into FM signal and launches through antenna to modulating emission circuit after receiving identification.The electronics package B in another shelter on the car receives this signal through frequency conversion, frequency discrimination, after the password identification, triggers electronic switch, and the oil circuit on the car, circuit are turn-offed, and car does not start.If chaufeur is pressed intercom push key, at this moment, the contact on the electronics package C mouth car of carrying between the electronics package A in shelter is as a pair of interphone, different is, bus equipment is to be in to listen the position, still says the position, is controlled by the electronics package C that carries fully.The soft program in the read-only memory (ROM) decides this process in the micro controller system by being cured to of weaving in advance.If car is by people Kaiyuan City, the electronics package under power of carrying, can report that this department opens high-power receiving device to traffic management system.Networking covers the whole nation between each city.Working process is, traffic management system is with the password code name of lost vehicles, the input microcomputer, this number of microcomputer is delivered to frequency modulated transmitter, launches one group of frequency modulation on pulse via antenna, convert receiving condition then immediately to, electronics package A on the car receives this signal, after frequency conversion, frequency discrimination, identification, exports one group of FM signal immediately as answer, the length of output pulse is determined by the soft program of finishing in advance.The machine of traffic management system is in receiving condition at this moment, and directional rotating antenna receives this signal, and through the frequency modulation machine demodulation, the one tunnel delivers to microcomputer discerns, and whether loses the number to be levied of car vehicle to determine this signal; Analog to digital conversion circuit is delivered on another road, converts the field intensity amplitude of the signal that receives to digital signal, delivers to microcomputer, microcomputer dependence program converts thereof into visual field intensity and shows, direction is presented on the screen and shows, and chopping machine prints it, can obtain the orientation result.If the networking of contiguous city can be known the concrete orientation of vehicle immediately.The emission of traffic management system, the directional rotating antenna of receiving processing system adopt the little directional antenna of directional pattern angle, lower end in the antenna vertical rod back and forth rotates with buncher 3 driven antenna axles 360 degree, and the aspect sensor on the antenna can adopt the Mageneto-sensitive type of photo-electric or Hall element class.Present embodiment has been adopted photo-electric, be provided with an infrared emission tube 4 above in vertical rod, establishing a disk 1 along with vertical rod rotation, be provided with below cooresponding on the antenna fixed support and be provided with 16 infrared receiver tubes 5 of a circle on the disk 2, disk 2 does not rotate with vertical rod.Relative disk 2 motions when antenna rotates like this, infrared emission tube on the disk 1 is along with motion, shine the infrared receiver tube 5 on the disk 2 successively, whether receive the project signal of infrared emission tube 4 like this with the infrared receiver tube 5 on the microcomputer mirror survey disk 2, just can record orientation, antenna place.16 infrared receiver tubes 5 just provide 16 reference coordinates in the scopes of 360 degree, the concrete continuous angle variation between two adoptors by the system controlled by computer transmitter and receiver, finishes once transmitting and receiving used time length and decide.The used cycle, short more its directivity was accurate more.The electronic switch of the set high-power emission of traffic management system, receiving processing system is to carry out the microcomputer instruction, the drive motor of control frequency modulated receiver, frequency modulated transmitter, antenna rotation, the electronic switch of the on/off of antenna upper position sensor.Q
