Ultrasonic detector 201,202,203....... structure and principle of work in the car:
Hardware is formed and principle of work:
As shown in Figure 5, detector mainly is made up of ultrasonic transmit circuit and ultrasonic testing acceptor circuit and Single Chip Microcomputer (SCM) system three parts.Employing AT89S51 micro controller system is realized the control to CX20106A receiving chip and super sonic modular converter.Wherein, Fig. 6 is the square-wave pulse of 38KHZ for ultrasonic transmit circuit schematic diagram: single chip computer AT 89S51 produces frequency by software at the P1.0 pin, through phase inverter U4AA, U4BA, U4CA, U4DA, U4EA control the super sonic that ultrasonic transmitter T sends out 38KHZ.Fig. 7 is a super sonic receiving test circuit schematic diagram: adopt integrated circuit CX20106A, this is the special chip that a infrared ray detection receives, its carrier frequency 38KHz is comparatively approaching with range finding ultrasonic frequency 40KHz, can utilize it as the ultrasonic testing circuit.Experimental results show that it has very high sensitivity and stronger antijamming capability.Receive 1 pin that imports integrated circuit CX20106A behind the signal of projector T into as R and amplify shaping, detection is after the 7 pin output low levels of integrated circuit CX20106A, when R does not receive the signal of projector T, the 7 pin output high level of integrated circuit CX20106A, the size of appropriate change C4 can change sensitivity and the antijamming capability of accepting circuit.It is the square-wave pulse of 38KHZ that system works principle: single chip computer AT 89S51 produces frequency by software at the P1.0 pin, through phase inverter U4AA, and U4BA, U4CA, U4DA, U4EA control the super sonic that ultrasonic transmitter T sends out 38KHZ.The detection INTO pin that do not stop of micro controller system just thinks that super sonic returns when the level of INTO pin becomes low level by high level then.The data of being counted are exactly the time that super sonic experiences, just can obtain the distance between detector and the obstacle by converting, when not having movable people or vehicle window to wait for bus the internal state unmodified in the car, this numerical value is unmodified, as the people into the car the time, distance between detector and the obstacle is dwindled, single chip computer AT 89S51 output voltage rises, when the people destroys vehicle window, distance between detector and the obstacle is increased, and single chip computer AT 89S51 output voltage can descend, when the numerical value of this rising or decline reaches default numerical value, so just can confirm to detect the abnormal condition of vehicle, output abnormality signal high level A.Anti theft host 101 is by micro controller system IC1 control and processing data, the input port of ultrasonic detector is eight I/O mouths of P0.0-P0.7 of corresponding micro controller system IC1 respectively, anti theft host 101 is under anti-theft state, anti theft host 101 can read ultrasonic detector 201 respectively, 202,203 normal status value N also is recorded in respectively in the anti theft host 101, as the people illegally into the car, break glass or open by force in the row and can cause corresponding ultrasonic detector 201 case the time, 202, thereby the change of 203 N value produces an energizing signal A, energizing signal A is sent to any I/O mouth of P0.0-P0.7 of the micro controller system IC1 of anti theft host 101, micro controller system IC1 promptly starts alert program, micro controller system IC1 is by high level of I/O mouth P1.1 output, controlling a relay connection high-decibel alarming horn 302 gives the alarm, the communication serial port of micro controller system IC1 gives GSM or cdma wireless communication module 301 for a string data B simultaneously, wireless communication module 301 is GSM or CDMA modules of using always, can realize dialing, conversation, function such as send short messages, receive when module and to comprise dialing telephone number, during data B such as alarm code, will send alerting signal to the phone of appointment according to the information in the data B. realize wireless alarm being sent to the phone of vehicle car owner appointment, realize in time notifying car owner's function by GSM or cdma wireless communication module 301
Fig. 8, Fig. 9 are the Digiplex structured flowchart, comprise transmitter portion and receptor part, command and control system adopts the KEELOQ rolling code, KEELOQ is rolling coding and the demoder of being released by the little core of U.S. Microchip company, adopt the KEELOQ rolling code algorithm of high security, make data transmission have high confidentiality, the code of each transmission all is unique.The probability that same remote controller (wireless accessory) sends duplication code prevents the problem that password is decrypted guaranteeing not repeat (every day is by about 10 times) in 18 years under the KEELOQ technology with this.At the inferior position that the few bottleneck of fixed code encoding amount and data very easily are decrypted, because the rolling code coded system, each sign indicating number that sends is all inequality, so have tight security (traditional fixed code remote control very easily is replicated or scans).When projector pushes button, the rolling coding chip can produce a unique code, this code sends in the acceptor circuit of receptor by radio transmitter, confirm the legal remote controller of whether appointment after the decoding of the decoded device of this code, if just export the P1.4 I/O mouth of a high level to anti theft host 101 micro controller system IC1, micro controller system IC1 will start anti-theft program and entered anti-theft state this moment, when projector pushes button once more, the rolling coding chip of receptor is done corresponding decoding and is confirmed the P1.4 I/O mouth of output low level in back to anti theft host 101 micro controller system IC1, micro controller system IC1 will withdraw from anti-theft program and close anti-theft state at this moment, realizes whether remote-control anti-theft main frame 101 enters anti-theft state.
