Compared with the prior art the utility model has following characteristics:

1. password: traditional cryptographic key adopts the numerical key of telephone key disc type, and password is a string Ah position uncle numeral, not only difficult note but also easily make mistakes.This annunciator is only used red green two key buttons, and password is one group of cross pithy formula, for example: " green, red, green, red, green, red, red, green, green, red ", can be combined into 1000 groups of passwords, operated key is simplified only surplus two keys, easily remembers easy to operate.Only need click green color key when flame-out and just can finish encryption.Also can correctly input password even have gloves on or in the dark.Just in case cryptocompromise can be opened host box voluntarily, stirs a P cock, enables another set of standby password.

2. sensor: adopt the displacement shocks sensor, fuse with main frame, sensitive, reliable, body is little.

3. audio alert: replace traditional " ticking " to report to the police with voice, expression content is abundant, both can point out deciphering, encrypted state, also can directly call for help.

4. power consumption: owing to adopt CMOS integrated circuit and relay power save circuit, power consumption is atomic, has both made to be installed on the locomotive that does not travel for a long time, the not enough warning failure phenomenon of storage battery electric energy also can not occur.

Below in conjunction with drawings and Examples the utility model is elaborated.

Fig. 1 is the utility model self-propelled vehicle voice burglar alarm schematic circuit diagram;

Fig. 2 is the utility model self-propelled vehicle voice burglar alarm schematic appearance.

As depicted in figs. 1 and 2, the utility model adopts decade counter to release decoding circuit IC1, settles diode respectively at pin 1～11, according to the diode of settling diverse location and quantity, forms different codings.By AN1 and AN2 input password, under the time-lag action of R4, C2, make pin 15 of IC1 be in active potential, satisfy IC1 counting condition, from a string direct impulse of pin 14 inputs, finally make pin 11 outputs become 1 by 0.In order to increase the decoding difficulty, the time delay circuit of R5, C3 is set, and by after 9 paraphase of inverter ic 2 pin, in pin 8 outputs one negative going pulse, make the bistable circuit upset of forming by 3,4,5,6 pin of R7, R8, C4 and IC2 by D4, pin 4 becomes 1 by 0, one the tunnel makes aerotron BG conducting through R6, signal lamp LED opens bright, and the relay power save circuit of being made up of R9, C5, D5, J starts, and the relay contact JK that is serially connected in self-propelled vehicle electric switch loop connects.Sound circuit is triggered through C9 in another road, and IC3 amplifies by C13 input power amplifier, sends " after drinking not Kai Che " voice by loud speaker.Special needs to be pointed out is, when starting motor-driven vehicle, disturb for sound circuit is exempted, the special setting exempted from interfered circuit, by the time-lag action of R8, C4, makes bistable circuit pin 6 postpone three seconds by 1 change 0, the sound circuit dead electricity can not disturbed disorderly newspaper phenomenon in motor-driven vehicle going.

Add a negative going pulse when pressing AN1 at IC2 pin 5, bistable state is resetted, pin 4 becomes 0 by 1, and aerotron BG ends, and the relay power save circuit resets, and JK disconnects, and self-propelled vehicle is flame-out, and pin 6 becomes 1 by 0, and sound circuit gets electric, and complete machine is in waits for the state of alert.Pin 6 triggers sound circuit through C8 and sends " having a nice trip " simultaneously.

Work as shock sensor, the single stabilization delay circuit that triggering is made up of R17, R18, C17, IC2 pin 10,11,12,13, one the road triggers sound circuit from pin 10 by C10 sends " having a nice trip ", one road pin 12 charges to capacitor C 18 by R19, when C18 voltage reaches the 1/2VDD of IC2, the pin 2 of IC2 becomes 1 by 0, trigger sound circuit send " catch a thief! Catch a thief! " report to the police.During motor-driven vehicle going, owing to D4, D5 clamping action, the pin 2,10 of IC2 is low level, random warning can not take place.

As input password by mistake or start by force, C18 is by D7, R20 discharge, and the pin 2 of IC2 becomes 1 by 0, triggers " catching a thief immediately! " report to the police.

The utility model is manipulated more convenient:

1. start: when opening car door, shaken the annunciator main frame that is installed on the car door, loudspeaker under the operator's compartment promptly send the voice of " having a nice trip ", press cryptographic key in ten seconds, correctly input password, loudspeaker send " after drinking not Kai Che " again, signal lamp on the main frame opens bright simultaneously, the expression successful decryption, chaufeur can inject key as usual, starts the locomotive that travels.

2. stagnation of movement: flame-out earlier when stopping, key button again, loudspeaker send " having a nice trip ", and the synchronous signal lamp extinguishes, and expression is encrypted and is finished, and locomotive is on the alert, and chaufeur can be extracted key, locks that car door is relieved to be left.

3. antitheft: when the robber pries open car door, touch annunciator, loudspeaker are newspaper " having a nice trip " earlier, if do not input password in ten seconds, or inputs password by mistake, or starts locomotive by force, and loudspeaker are just called on urgently and " catched a thief! Catch a thief! ", at this moment locomotive also can't start.The sound that " catches a thief " will continue to stop automatically in 15 seconds, if touch, then call on urgently more again.

4. anti-the misfortune: when chaufeur was subjected to kidnapping threat, he can click the encryption key button alertly, the flame-out immediately stagnation of movement of locomotive, and loudspeaker are called on urgently and " are catched a thief simultaneously! ", make the bandit stricken, the public security officer hears the news and surrounds and seize.

The utility model comprises that password key button AN1, AN2 on a main frame 1 and the main frame and signal lamp 2, loudspeaker Y two parts form.Main frame is directly installed on the car door as the cigarette case size, and will export input plug and be serially connected in respectively between locomotive electric door lock (four seats) connector, the loudspeaker that the wire joint operator's compartment is beneath, another line ground connection " bonding " only needs promptly install half an hour.

By further simplified structure, this annunciator can be used for motor bike, mini-motorcycle, bicycle etc.
