Abstract
An anti-theft device capable of recognizing voice belongs to the technical field of household electronic appliances and relates to an electronic anti-theft device. The recording circuit input end of the device is connected with a high fidelity microphone; the output end is divided into three channels, one channel is connected with a voice storing circuit, another channel is connected to a voice comparing circuit, and the other one forms a group of optimal codes by an encoding circuit; a CPU (central processing unit) of a singlechip stores the random codes corresponding to each segment of voice to a voice receiving control circuit; the CPU detection port is connected to an infrared sensor; and the output port is connected to the input end of a GPRS (general packet radio service) emitting circuit. The device records the habitual dialogues of the master into the record storing circuit one by one, starts the voice control circuit at once when the infrared sensor detects out an abnormal information, and randomly sends out a group of voices; and if no response or the party answers wrong, the device sends out an alarm voice and sends out an early warning information by GPRS. Due to the fact that the codes of language of the master are different in thousands of ways, the decoding difficulty of the theft is greatly increased and the anti-theft effect is significantly improved.
Description
Technical field
The utility model belongs to domestic electronic utensil technical field, relates to a kind of electronic anti-theft apparatus.
Background technology
At present, Household anti-theft device is multifarious, and great majority are machinery, electronics or electromechanical, and each anti-theft device has the advantage of its protection, and the weakness of self is also arranged.Although antitheft means are more and more advanced in recent years, any product has certain rule after all, in case the burglar has grasped the rule that cracks, these anti-theft devices have just been lost use value.Therefore, the intellectuality of anti-theft device should be one of developing direction.
Summary of the invention
The purpose of this utility model is the anti-theft device that reaches anti-theft effect for a kind of mode that exchanges by man-machine sound of the problems referred to above design.
The technical solution of the utility model is: the recording circuit input end of this device connects the high-fidelity microphone, output terminal is divided into three the tunnel, one the tunnel connects the voice storage circuit, another road is to the speech comparison circuit, this two routes phonetic incepting control circuit switches, the coding circuit of leading up in addition forms one group of random code, the random code that the CPU of single-chip microcomputer is corresponding with each section voice is stored into the phonetic incepting control circuit, the output of phonetic incepting control circuit also is divided into two-way, the switching of one tunnel control recording circuit, another road is to the speech comparison circuit, and the speech comparison circuit outputs to audio amplifier circuit; The CPU detection port is connected to infrared sensor, and CPU one road output port is to the input end of GPRS radiating circuit.
This device is talked with one by one typing voice memory circuit of term with chamber owner's custom, when infrared sensor detects abnormal information, at once start voice control circuit, send at random one group of voice, if response or litigant do not tackle mistake, this device voice that give a warning, and send early warning information by GPRS.
The beneficial effects of the utility model: the utility model is Data Entry Room owner's custom dialogue term in advance, when it is on the alert, detects the indoor abnormal conditions that have, and at once starts voice control circuit and inquires.Because chamber owner's speech habits vary, and have greatly increased the difficulty that the robber cracks, and have significantly improved anti-theft effect.

Accompanying drawing 1 is the utility model circuit block diagram.
Embodiment
This crust of the device adopts commercially available standard casing, internal circuit board, and external microphone, loudspeaker and infrared detection probe if need to improve monitoring range and sensitivity, can also adopt other physical detection probe simultaneously.
Recording circuit on the circuit board adopts the programmable, intelligent speech chip (PM60 series) of built-in flash storer, its input end connects the high-fidelity microphone, and output terminal is divided into three the tunnel, the one tunnel and connects the voice storage circuit, one the road to the speech comparison circuit, and one the road to coding circuit.The voice storage circuit can adopt PM60 chip internal storer, but also external memorizer.Recording circuit is switched by the phonetic incepting control circuit.When needing in advance Data Entry Room owner voice, start recorded program, deposit one by one recorded speech in storer; When this device was on the alert dialogue, the voice signal that enters speech chip through microphone was sent into the speech comparison circuit, compares with the conversation content of recording in advance.One tunnel output of recording circuit forms one group of random code by coding circuit, and the random code that the CPU of single-chip microcomputer is corresponding with each section voice is stored into the phonetic incepting control circuit, plays the effect of voice messaging in the identifying call storer.The output of phonetic incepting control circuit is divided into two-way, the switching of one tunnel control recording circuit, and another road is to the speech comparison circuit.The speech comparison circuit outputs to audio amplifier circuit, then outputs to loudspeaker; The CPU detection port is connected to infrared sensor or other physical sensors, with abnormal conditions in the sensing chamber.CPU arranges one road output port to the input end of GPRS radiating circuit (commercially available GPRS circuit module), when the results abnormity of speech comparison circuit need to be reported to the police, sends information warning to chamber owner's mobile phone.
This device is talked with one by one typing voice memory circuit of term with chamber owner's custom, when infrared sensor detects abnormal information, at once start voice control circuit, send at random one group of voice, if response or litigant do not tackle mistake, not according to the voice answering of recording in advance, this device voice that give a warning, and send early warning information by GPRS.
Claims (1)
1. the anti-theft device of a sound recognition, it is characterized in that: the recording circuit input end of this device connects the high-fidelity microphone, output terminal is divided into three the tunnel, one the tunnel connects the voice storage circuit, another road is to the speech comparison circuit, this two routes phonetic incepting control circuit switches, the coding circuit of leading up in addition forms one group of random code, the random code that the CPU of single-chip microcomputer is corresponding with each section voice is stored into the phonetic incepting control circuit, the output of phonetic incepting control circuit also is divided into two-way, the switching of one tunnel control recording circuit, another road is to the speech comparison circuit, and the speech comparison circuit outputs to audio amplifier circuit; The CPU detection port is connected to infrared sensor, and CPU arranges one road output port to the input end of GPRS radiating circuit.
