The utility model is also further realized by software:

Operating sequence software has the function of automatic identification traffic information broadcasting signal and hand signal among the micro controller system IC6, these functions are that frequency is searched for automatically, disturbance rejection, subchannel signal aspect and indication (TP), the emergency information signal switches and demonstration (Ta), paging signal switches (BP), antitheft speed-slackening signal switches (EWS), button S1 automatic/hand subchannel SCA switches, button S2, the S3 volume is regulated, the manual vehicle-locking signal of button S4 switches and shows, under lock car state, S2, S3 (0,1) password unlocking, under the S4 down state, S2, S3 (0,1) password setting or replacing, above-mentioned functions is achieved in that

After start under the non-locking s-f situation, IC6 the 7th pin output high level, pass through R31, R32, R1 delivers to the K end of CT1 and CT2, deliver to the K end of CT3 and CT4 by R2, deliver to the K end of CT5 and CT6 by R3, this moment capister CT1, CT2, CT3, CT4, CT5, CT6 is high capacitance, three loop resonant frequencys are in the low frequency stage simultaneously, when not receiving the MF-RDS signal, and IC6 meeting automatically regulating voltage, from high to low, when being adjusted to a certain voltage, three loops have received that resonance when a certain fixed frequency, promptly received the MF-RDS signal, IC6 voltage is constant promptly to lock this frequency voluntarily, so realized the automatic search function of frequency; This moment, light-emitting diode D5 amber light was bright, had entered the traffic information broadcasting signal coverage to show this machine; System begins MF-SCA broadcasting, in case automobile sails out of signal coverage, IC6 can repeat said process, until finding new Frequency point, locks and starts working, and therefore, system has national roaming function;

IC6 has recognition function to the interfering signal of IC2 input, when finding to disturb, goes out the operation level that control signal changes IC1 the 15th pin by IC6 the 19th human hair combing waste, so gain descends in the IC1, removes more weak interfering signal, reaches jamproof effect;

When IC6 received the traffic information broadcasting emergency information signal of importing by IC2, IC6 the 6th pin output high level was to the receiver of any state, realize MF-SCA broadcasting without exception, at this moment light-emitting diode D6 red light is luminous, IC6 the 6th pin output high level, send into the Q5 base stage by R24, make Q5 work, JZ2 adhesive, the 3rd and the 6th pin conducting, system is connected, cut off auto audio equipment power supply V1 simultaneously, announcement finishes, and IC6 can make the system recovery virgin state;

IC6 is to the paging signal of input, at first carry out addressing, IC6 the 16th pin output addressing identification signal is to IC7 the 3rd pin, after assert address code, IC6 the 6th pin output high level, cut off auto audio equipment, achieve the FM-SCA receiving condition, the high level of IC6 the 11st pin output is simultaneously sent into the Q8 base stage by R39, make Q8 work, JZ5 the 13rd, the 9th pin is connected, the 4th, the 8th pin is connected, and makes C27 changing-over C58, C29 changing-over C59, reaches the 2nd subchannel mode of operation, other receivers continue to receive first subchannel, not influenced by paging;

IC6 at first carries out addressing to the antitheft speed-slackening signal of input, and IC6 the 16th pin output addressing identification signal is to IC7 the 3rd pin, and after assert address code, IC6 the 5th pin output high level connects the Q6 base stage by R26; Make Q6 work, make the JZ4 adhesive, JZ4 the 3rd and the 1st pin open circuit are because igniter for automobile is connected in series power supply with automobile storage battery V1 by JZ4 and JZ3, therefore, JZ4 the 1st pin and the 3rd pin open circuit back igniter for automobile can't be worked, so reach flame-out braking, realize anti-theft column lock car function, in a single day this function is carried out and just can be kept for a long time, cancellation lock car still must be by Traffic Announcement radio station emission erasing sign, and this moment, virgin state was promptly recovered by system;

Button S1, S2, S3, S4 is by manually providing IC6 signal, and IC6 has recognition function to incoming signal, when system is in the MF-SCA mode of operation, button S1, IC6 can assert that operation requirements exempts to listen, so IC6 the 6th pin output low level is sent into the Q5 base stage by R24, Q5 is ended, the Q5 collecting electrode becomes high level, and JZ2 discharges, the 3rd and the 6th pin open circuit, cut off the operating voltage of IC5 the 5th pin, this power discharging integrated block quits work, and simultaneously, connects JZ2 the 3rd and the 1st pin, the 1st pin and the 7th pin of P2 are connected, auto audio equipment power supply V1 is provided, and JZ1 the 16th pin working power disconnects, and JZ1 is release position, at this moment, auto audio equipment temporarily stops MF-SCA broadcasting, and the 2nd and the 3rd pin of P2 is connected, and the 5th and the 6th pin is connected, be that auto audio equipment and auto loud hailer are directly connected, auto loud hailer is worked under auto audio equipment output;

When button S2 or S3, IC6 makes identification to incoming signal, when regarding as the volume increase or reducing (be increase from the signal of IC6 the 1st pin output, the 2nd pin is to reduce), the certain level control Q4 of IC6 the 4th pin output carries out output voltage to be regulated, and plays the effect that volume is regulated.It is linear that volume is regulated;

During button S4, IC6 makes identification to incoming signal, and at this moment, S2 and S3 are 0 or 1 the cryptographic key that is provided with, and the car owner can freely select and establish 8 figure place passwords, and when not setting, the D7 green light does not work, after setting is finished, and the D7 flicker.Pin the password that the S4 repeat key is provided with then, can realize unblanking, repeat key again by S4, be in lock car state again, when lock during car, IC6 the 13rd pin output low level, send into the base stage of Q7 by R28, Q7 is ended, JZ3 discharges, and the 3rd pin of JZ3 and the 6th pin disconnect, and makes the 1st pin and the 4th pin open circuit of P3, cut off igniter for automobile this moment, realized the manual lock car; When unblanking,, the password that is provided with is imported IC6 by S2 (0) and S3 (1), after assert, can unblank through pinning the S4 key.
