In addition, described talkback burglar alarm system can also add amplifying circuit in the part that needs amplifying signal as required.
Its principle of work is specific as follows:
When the wireless detector or the wiresounding device that adopt, when monitoring abnormal conditions, then send alerting signal, and alerting signal sent to CPU, after CPU received alerting signal, the control alarm sent warning signal or control dialing decoder module or 3G module and dials the telephone number that sets in advance;
In addition, in the time that one sets in advance, when the signal number of times of ringing a doorbell that receives surpassed the number of times set in advance and ring unanswered, CPU then controls the dialing decoder module or the 3G module is dialed the telephone number that sets in advance;
Wherein, described dialing decoder module, comprise and be used for realizing HT9200 chip that dials and the HT9170 chip that is used for decoding, after CPU receives alerting signal, can start the HT9200 chip and dial the telephone number that sets in advance, during dialing, CPU controls first relay, the first audio-video wireless module is communicated with the dialing decoder module, first loudspeaker then disconnects with the circuit that the first audio-video wireless module is connected, CPU also controls second relay simultaneously, the first audio-video wireless module is communicated with the dialing decoder module, first microphone then disconnects with the circuit that the first audio-video wireless module is connected, after the telephone number corresponding mobile terminal that sets in advance was connected, the voice signal on doorway was by second microphone, the second audio-video wireless module, the first audio-video wireless module, first relay, the telephone number corresponding mobile terminal that sends to and set in advance behind the dialing decoder module; And the voice signal at portable terminal place is sent to the doorway through second relay, the first audio-video wireless module, the second audio-video wireless module and second loudspeaker, allows the doorway talker hear, thereby realizes intercommunication.
When the user of described telephone number corresponding mobile terminal wants to open the door for the doorway talker, can press the button of the portable terminal that sets in advance, when the dialing decoder module, specifically be after HT9170 chip in the dialing decoder module is received button corresponding key sound signal, it is decoded, decoded signal is sent to CPU, and CPU just controls door-lock opening.
Described dialing decoder module also is used for dialing the telephone number that sets in advance after CPU receives alerting signal, carries out alarm.
In the time that one sets in advance, indoor have a man-hour, can also answer, this moment, CPU controlled first relay and second relay, make the line conduction of first loudspeaker, first relay and the first audio-video wireless module, make the line conduction of first microphone, second relay and the first audio-video wireless module, first loudspeaker is used for answering the voice signal of playing doorway second microphone reception; Second microphone is used for the voice signal in the receiving chamber, plays by the second outdoor loudspeaker at last, thereby realizes indoor and the intercommunication doorway.
Wherein, described first microphone and second microphone are used for voice signal is changed into audio electrical signal;
Described first loudspeaker and second loudspeaker are used for converting audio electrical signal to voice signal.
See also Fig. 4, the embodiment of the invention two also provides a kind of antitheft method of intercommunication that adopts described talkback burglar alarm system, said method comprising the steps of:
S401: the signal number of times of ringing a doorbell that detector monitors receive to abnormal conditions or in the time that sets in advance surpasses number of times and the ring unanswered who sets in advance;
S402:CPU control dialing decoder module is dialed the telephone number that sets in advance.
Wherein, detector monitors is further comprising the steps of after the step of abnormal conditions:
CPU control alarm sends warning signal.
Wherein, further comprising the steps of after the described step of dialing the telephone number that sets in advance:
When described telephone number was connected, then the audio electrical signal that will be converted to by the voice signal on doorway was sent to described telephone number corresponding mobile terminal.
Further comprising the steps of after the described step of dialing the telephone number that sets in advance:
When described telephone number is connected, receive the button of the portable terminal of pressing that sets in advance;
The dialing decoder module receives button corresponding key sound signal, the button sound signal is decoded, and send to CPU;
