Embodiment
As Fig. 1～shown in Figure 4, a kind of vehicle-mounted antitheft safety feature that is used for comprises vehicle-mounted code reader, cipher key, and described cipher key 1 inside is provided with the mode switch 4 of determining the different operating state, and is connected with described vehicle-mounted code reader 2 by USB interface 3; Cipher key 1 is connected with power circuit 11 by USB interface, and according to the duty of mode switch 4, the code data that scrambler 7 is set exports described vehicle-mounted code reader 2 by electronic switch 8 to through USB interface 3.The control chip model of described scrambler 7 is SG2262.Vehicle-mounted code reader 2 is made up of decoding circuit 9, driving circuit 10, power circuit 11, described power circuit 11 is connected with USB interface 3, decoding circuit 9, driving circuit 10 respectively, the input end of decoding circuit 9 links to each other with USB interface 3, and its output terminal is connected with driving circuit 10.Described decoding circuit 9 control chip models are SG2272.
Get to following time when mode switch 4, mode switch 4 is connected with ground, and the mode state of electronic switch 8 is 000, and this moment, three road X paths of electronic switch 8 were connected.The function on that is equivalent to cipher key 1.2 USB interface 3 when cipher key 1 inserts vehicle-mounted code reader by USB socket energized VCC, is connected electronic switch 8, outputs to the 2 pin bX end of electronic switch 8, power supply is provided for cipher key 1.12 human hair combing wastes by electronic switch 8 go out 14 pin of TE low level signal to scrambler 7, scrambler 7 sends coded signal, 17 human hair combing wastes of encoded device 7 send the DOUT data-signal to 5 pin cX of electronic switch 8 end OPADD sign indicating number, numeric data code, synchronous code to vehicle-mounted code reader 2 in 14 pin of decoding circuit 9, enter password identification.Cipher key 1 sends four group identification codes, address code, and 14 pin of input decoding circuit 9 read, discern; After decoding circuit 9 detects correctly, pilot lamp LED is glittering, the expression password detects correct, and then by sending instruction, the base stage of high level OUT signal of 17 pin output by decoding circuit 9 transistor Q1 to the control relay circuit 12, close conducting through transistor Q1 is full, Control of Automobile engine management unit ECU power supply relay P1 closure, and then Control of Automobile engine management unit ECU power connection, make automobile finish startup. when password not match, or when not inserting cipher key 1, the decoding circuit 9 of vehicle-mounted code reader 2 inside just can't be exported the high level drive signal, and transistor Q1 ends, cause the relay P1 of automotive interior to be failure to actuate, motor car engine administrative unit ECU power supply can't be connected, and automobile can't be started, and reaches the purpose of safe antitheft.
