Description
Technical field
The utility model relates to simple and easy security protection audible-visual annunciator, belongs to computer realm.
Background technology
The alarm for safety guard kind of Vehicles Collected from Market is various, and designed system is very complicated mostly, although function is much very complete, but cost is too high, expensive, is not suitable for small user's requirement.
Summary of the invention
The utility model purpose is too high, expensive in order to solve existing alarm for safety guard cost, is not suitable for the problem that the small user requires, and a kind of simple and easy security protection audible-visual annunciator is provided.
Simple and easy security protection audible-visual annunciator described in the utility model, it comprises single-chip microcomputer, door lock detector, infrared eye, reset circuit, seven hop count LED charactron and audible-visual annunciators,
Gate inhibition's information output of door lock detector links to each other with gate inhibition's information input terminal of single-chip microcomputer, the infrared information output terminal of infrared eye links to each other with the infrared information input end of single-chip microcomputer, the reset instruction output terminal of reset circuit links to each other with the reset instruction input end of single-chip microcomputer, the idsplay order output terminal of single-chip microcomputer links to each other with the input end of seven hop count LED charactrons, and the alarm command output terminal of single-chip microcomputer links to each other with the input end of audible-visual annunciator.
Advantage of the present utility model: simple in structure, adopt two-way external interrupt input gate inhibition and infrared acquisition two paths of signals, warning message can be shown at charactron after the look-at-me input, and output sound and light alarm signal, cost is low, and cost performance is high.
Description of drawings
Fig. 1 is the structural representation of simple and easy security protection audible-visual annunciator described in the utility model.
Embodiment
Embodiment one: below in conjunction with Fig. 1 present embodiment is described, the described simple and easy security protection audible-visual annunciator of present embodiment, it comprises single-chip microcomputer 1, door lock detector 2, infrared eye 3, reset circuit 4, seven hop count LED charactron 7 and audible-visual annunciators 8,
Gate inhibition's information output of door lock detector 2 links to each other with gate inhibition's information input terminal of single-chip microcomputer 1, the infrared information output terminal of infrared eye 3 links to each other with the infrared information input end of single-chip microcomputer, the reset instruction output terminal of reset circuit 4 links to each other with the reset instruction input end of single-chip microcomputer 1, the idsplay order output terminal of single-chip microcomputer 1 links to each other with the input end of seven hop count LED charactrons 7, and the alarm command output terminal of single-chip microcomputer 1 links to each other with the input end of audible-visual annunciator 8.
It is the single-chip microcomputer of ST89C51 that single-chip microcomputer 1 is selected model.
Under the normal condition, seven hop count LED charactrons 7 show 0, and when the generation gate inhibition reported to the police, system sent sound and light alarm information and shows 1 at seven hop count LED charactrons 7; , system sends sound and light alarm information and shows 2 at seven hop count LED charactrons 7 when infrared alarm occurs.After the button of only pressing reset circuit 4 by owner makes system reset, could remove sound and light alarm and the numeral of seven hop count LED charactrons 7 is reset to 0.
The LED charactron is the device that is come display field by light emitting diode, utilizes quaternity common cathode charactron as the display element of circuit, adopts the mode of dynamic scan to show, has saved I/O mouth resource, simplifies circuit.With 1,001,004 while ground connection, four will show identical content simultaneously.
When red represents that all are normal.When infrared alarm or gate inhibition occuring report to the police, red light goes out, and green light is bright, the warning of sounding of the loudspeaker of audible-visual annunciator 8.
Embodiment two: present embodiment is described further embodiment one, and it also comprises manual input warning circuit 5, and the manual alarm command output terminal of manually inputting warning circuit 5 links to each other with the manual alarm command input end of single-chip microcomputer 1.
