The specific embodiment
The present invention is described in detail below in conjunction with the drawings and specific embodiments.
Automobile of the present invention does not have key and enters structure with antitheft location and navigationsystem, as shown in Figure 1 and Figure 2, comprise that no key enters subsystem, GPRS anti-theft and alarm subsystem and GPS location navigation subsystem, no key enters subsystem and comprises MCU module 3 and the inductor 1 that is connected, and MCU module 3 is arranged at Che Nei and is connected with circuit control module 2 in the car; GPRS anti-theft and alarm subsystem comprises ARM module 4, and ARM module 4 is connected with MCU module 3 by bus, and ARM module 4 also is connected with mobile phone 7 with GPRS module 6 successively; GPS location navigation subsystem comprises GPS module 5, and GPS module 5 is connected with ARM module 4.
As shown in Figure 2, also be connected with on the MCU module 3: low frequency transceiver module 8, high frequency transceiver module 9.
Also be connected with on the ARM module 4: video module 10, audio-frequency module 11, CAN bus interface 12, extended network interface 13.
Automobile of the present invention does not have the working process that key enters with antitheft Position Fixing Navigation System,
1, door contact interrupter implementation process
The inductor 1 that the car owner carries 3 to 5 meters in distance automobile apart from the time, the low frequencies signal activation that inductor 1 is controlled by system MCU module 3 in the car, carry out the identification of ID coupling, and respond with high-frequency data, through mutual emission and reception repeatedly, inductor 1 passes through with the ID coupling of Che Nei system, and then the Che Nei system can automatically perform the lock action of opening the door, and has realized that no key induction opens the door.
When automobile stops to travel, when inductor 1 left outside the scope of 3 to 5 meters in car with the car owner, the LF communication of system MCU module 3 detected inductor 1 not in scope in the car, then carries out and locks a door, rises the vehicle window action, and open anti-theft state.If lock a door not success (not shutting as door), then GPRS module 6 is initiated voice conversations to designated mobile phone 7, and with the prompting failure of locking a door, the voice conversation prompting is until the success end of locking a door.Anti-theft system after locking a door is ready, and monitors vehicle condition information and security situation at any time.
The public frequency range of 433MHz is used in system's medium high frequency communication, and what low frequency used is the 125KHz frequency range, and for high frequency antenna, the Che Nei system adopts lead formula antenna, and 1 of inductor adopts the PCB antenna, and low-frequency antenna all adopts inductance coil.The low frequencies signal is in the timing working pattern of adjustable time gap, and whether detecting real-time has inductor 1 in its scope.Corresponding executable operations is sent control signal by MCU module 3, drives relay, and then controls corresponding motor realize opening the door lock and remove antitheft.
2, automobile anti-theft alarm, location navigation implementation process
Automobile is in legal process of travelling, GPS location navigation subsystem normal operation, simultaneously the LF communication of system MCU module 3 is being detected inductor 1 whether in car always in the car, when car is robbed, and carrying inductor 1, the car owner leaves car, the detecting of Che Nei system then can appear less than the situation of inductor 1 in car, the processing that automobile is robbed will be done by system this moment, with automobile in the process of moving real time position report to the mobile phone 7 of car owner's appointment, the car owner realizes the control corresponding operation by 7 pairs of automobiles of mobile phone simultaneously, plays anti-snatch effect.
When automobile be subjected to surpassing the vibrations of normal amplitude, by the illegal driving door or when illegally being started, GPRS anti-theft and alarm subsystem is carried out following operation, the mobile phone 7 that the location information and the status information of car sent to appointment, mobile phone 7 is after receiving information, by sending control corresponding sign indicating number information, realize control to automobile to the Che Nei system.Simultaneously real-time tracing is carried out in the position of car, reach theft-proof purpose.
That is to say, when illegal operation, GPS module 5 sends the data message of location to ARM module 4, treater is formed data packet with the illegal operation code of this information and car, by GPRS module 6, send to designated mobile phone 7, mobile phone 7 responds after receiving information, control information operation is sent to the Che Nei system, and GPRS module 6 receives control information, sends ARM module 4 to, carry out data interaction with MCU module 3 after treatment, MCU module 3 is converted to executable operations with corresponding control information, drives relevant actr, as outage, oil-break, with talk with in the car etc.
Automobile of the present invention does not have the principle of work that key enters with antitheft location and navigationsystem:
Host processing system is the dual processor pattern of MCU module 3 and ARM module 4.The outer inductor 1 of car was realized with being connected by the communication of low-and high-frequency combination of the interior system MCU module 3 of car.LF communication is physically realized by the mutual inductance of inductance coil, also is the magnetic flux letter principle (LFMC) of low frequency.Data are with the transmission of PWM modulation system, and frequency adopts 125KHz.High-frequency communication adopts the GFSK modulation, and the employing communication frequency is 433MHz, and antenna adopts wire antenna.2 controls of circuit control module through amplifying circuit, drive relay with actrs such as control associated motor by the I/O port controlling of MCU module 3 in the car.Energizing signal input is by being that MCU module 3 accessible high-low levels are handled with corresponding transform electric on the car.Realize by serial ports or other bus modes with ARM module 4 data-interfaces.
Automobile of the present invention does not have key and enters and antitheft location and navigationsystem, has improved the reliability and the validity of automobile burglar, has simplified switch Door Lock process.
