When microcomputer 1 is set in general doorbell functional mode, only make the first indication mechanism LED1 that warns on the actuating mechanisms 3 through commutation circuit 2, be that green LED is luminous, this moment is when being pressed as if the bell button 31 on the caution actuating mechanism 3, microcomputer only makes first sound generating mechanism 6, be the doorbell sounding, if a whole set of resisting alarm door bell system is imitative general doorbell function.When microcomputer 1 is switched into anti-theft modes, the second indication mechanism LED2 of microcomputer 1 on commutation circuit 2 order caution actuating mechanisms 3, promptly red LED is luminous, and the first indication mechanism LED1 is no longer luminous.Promptly sent signalisation microcomputer 1, and make second sound generating mechanism 7 when if detection agency 5 and door and window trespass this moment, and promptly warning horn and alarm bell make a sound.Of the present invention focusing on, this moment is with the luminous hint of the different indication mechanisms security personnel's situation within doors on caution actuating mechanism 3 panels.Only color is different with the second indication mechanism LED2 because of the first indication mechanism LED1, and general stranger has no way of detecting its difference and reflects within doors security personnel's situation, does not know promptly that this room is equipped with to save facility from damage or started, and natural vigilance also can reduce a little.After trespassing, the signal of detection agency 5 is also received by microcomputer 1 simultaneously and handles, and send timing pulse signal and make indication mechanism LED1 or LED2 flicker, this moment is if house owner or neighbours return or when being in outside the room, can utilize caution actuating mechanism 3 that bell button 31 is pressed, no longer make microcomputer 1 start the normal door the tinkle of bells after so pressing, but make second sound generating mechanism 7, promptly warning horn and alarm bell make a sound.So easy mechanism can make the house owner wait by initiatively starting warning horn and alarm bell by situation outside the room, can effectively draw back the ruffian with fear.Because of its profile and all similar general doorbell of function, also having no way of for the stranger learns is security system, thereby is difficult for going to pot or vigilance at ordinary times.
Now with the detailed description of Fig. 2 exemplary circuit structure of the present invention.
At first see the function of bell button 31 and indication mechanism LED1 and LED2.Total system is with power supply VCC power supply, and when being in general doorbell functional mode at ordinary times, microcomputer PORT1 export low (LO) signal, and transistor Q1 ends at this moment, and the relay R ELAY of commutation circuit is failure to actuate; And by high (HI) signal of microcomputer PORT2 output, so transistor Q2 conducting, transistor Q3 conducting and from the collector output voltage to diode VZ, and close contact usually through relay R ELAY, make wiring PI become positive voltage, and wiring P2 ground connection, electric current is through resistance R X to the first indication mechanism LED1 ground connection, so LED1 is luminous, show normal doorbell state this moment; Bell button 31 is pressed outside the room, wiring P1 and P2 short circuit, and the VZ diode is low, and microcomputer PORT3 receives low signal, and confirming button 31 is pressed, enabling gate the tinkle of bells sound.
When switching to the anti-theft warning function, the PORT1 of microcomputer exports high signal, so transistor Q1 conducting, relay R ELAY becomes logical, wiring this moment P1 ground connection, wiring P2 is that positive voltage makes electric current through the second indication mechanism LED2, resistance R X ground connection, so LED2 is luminous, this moment, the cresset indication was in alert status.Bell button 31 is pressed outside the room, wiring P1 and wiring P2 short circuit, and the VZ diode is low, and the PORT3 of microcomputer receives low signal, and confirming button 31 has been pressed, enabling gate the tinkle of bells sound.In other words, even switched to the anti-theft warning function, if detection agency 5 was not measured the house and trespassed this moment, only have general doorbell function after pressing bell button 31, only second indication mechanism LED2 light indication burglary-resisting alarm door bell this moment is in alert status.
When system switched to the anti-theft warning state, detection agency of being installed on door and window place or the wall such as magnetic reed switch 51 or pyroscan 52 detected when trespassing, and seasonal microcomputer 1 is sent signal and made second sound generating mechanism 7, and promptly warning horn and alarm bell make a sound.Simultaneously, PORT2 output becomes high and low, high timing pulse signal, causes the positive voltage of wiring P2 to cut in and out, the flash caution cresset that goes out when bright when forming LED2.As wiring P2 when being high, this moment, then diode VZ was low if press the button 31, and microcomputer 1 also can start warning horn or alarm bell generation sound after receiving this signal.
Another changes in the example in the present invention, when system switches to the anti-theft warning state and meets when trespassing, can make second sound mechanism 7, be that warning horn and alarm bell send one section sound and promptly stop ending, treating that house owner or other people initiatively press the button made microcomputer 1 start warning horn and alarm bell sounding at 31 o'clock again, reached the abrupt effect of drawing back with fear.
One change in the example in the present invention, the first indication mechanism LED1 and the second indication mechanism LED2 can be the indication mechanism LED3 of one, but can send different colours again, and its arrangement is shown in Fig. 3-2.
Above-mentionedly being illustrated as of the present invention illustrating, is not to enumerate its characteristic fully, so essential scope of the present invention is not limited by it.For example, above-mentioned first indication mechanism can be the mechanism that separates with second indication mechanism, also can be the structure of one and the indication that can send different colours by input signal.In addition, the mode that microcomputer makes second indication mechanism dodge and goes out also can change the mode that makes indication mechanism go out entirely into, more can make the ruffian not note changing therebetween and reduces notice.Certain first sound generating mechanism and second sound generating mechanism can also other different acousto-optics or the mechanism of action such as mechanism replace the function of doorbell or warning horn and alarm bell; And only display lamp number exchange when P1 and P2 exchange as if two wiring, apparatus function essence does not all change.In a word, spirit of the present invention and scope should be defined by claims, must have the present technique person of haveing the knack of can be revised as various variation in this scope.
