Description
The utility model has related to burglar alarm equipment field, is particularly for a kind of keyboard-type electronic anti-theft alarm controller.Be applicable to that the home dwelling burglar alarm uses, and also can be used for indoor safety precautions such as shop, office, warehouse.
In recent years, in order to safeguard the society and the safety of family's lives and properties, the molecule that avoids theft is entered the room, and row is stolen and destruction, has successively released many electronic anti-theft alarms, wired, have wireless; Have digital, have the magnetic key or the like, all different effects of having played safety precaution of degree of these electronic alarms.But these alarms part that also all comes with some shortcomings has influenced and has promoted and use.The wireless remote-controlled alarm device uses flexible safety, but telepilot itself is easily from body or lose, and influence is used, and also influences normal use when remote controller battery there is not electricity; The electron key alarm is more advanced, uses also easily, but circuit is complicated, cost is also higher, and all these is used for safe ready of domestic electronic alarm reliably and brings some inconvenience.
The purpose of this utility model is to disclose a kind of novel structure, circuit keyboard-type electronic anti-theft alarm controller reasonable, easy to use, with the effect of better realization burglar alarm.
Task of the present utility model is to realize by the cooperating of a cryptographic key tray salver and a control enclosure.Concrete controller is made up of keyboard case and control enclosure, and the output control signal is to an alarm, and alarm can independent external setting, also can be contained in the control enclosure.Keyboard case is a rectangle box body, keyboard, sound hole and pilot lamp are housed above, circuit board is housed in the box, keyboard can adopt telephone keypad, be connected on the input end of keyboard case circuit, can make keyboard case circuit output unlocking signal (correctly accessing to your password) or alerting signal (mistake accesses to your password) give control enclosure behind the number that input is set, control enclosure is operated in reset (release) state or alarm condition.The keyboard case circuit is a coded lock chip circuit, is electrically connected with control enclosure by connecting line.Control enclosure is the box body of a moulding, and box is provided with the input code knob, and the knob that locks adds release pilot lamp and alternating current jack, and is provided with external sensor terminals and external alarming device interface.Control circuit board is housed in the control enclosure.Control circuit has signal comparator circuit and signal output apparatus two parts, also can include warning circuit.Signal comparator circuit can be made up of the transport and placing device integrated chip, the unlocking signal of responsive keyboard case circuit, alerting signal and the manual make-and-break signal that adds lock signal and external sensor input, give signal output apparatus, the duty of control circuit through making circuit output high level or low level after relatively judging.Signal output apparatus adopts basic circuit for the moment, and two input end (reset terminal and trigger end) is connected on respectively on two transport and placing devices of comparator circuit, output termination one alarm.Circuit is like this design, and when an input end (reset terminal) was low (0) level, circuit was in (release) state that resets, no matter at this moment the level of trigger end is how, and the equal no-output of circuit; When reset terminal was height (1) level, circuit was in the vigilance task state, and at this moment, as long as low (0) level appears in trigger end, circuit is triggered, and the output alarm control signal is given alarm.
This practicality connects that external sensor is the breakaway-element sensor on the type control enclosure external sensor terminals, it can be magnetic switch, it also can be the human-body infrared sensing device, magnetic switch is contained on the door and window, infrared sensor is contained in indoor suitable place and gets final product, external warning device can be a sound loudspeaker such as voice, siren, also can be video recording equipment etc.
During use, keyboard case is contained in the suitable place of room door (window) outside, control enclosure is contained in indoor concealed place, connect connecting line and external sensor, optionally connect external warning device (to not connecing the control enclosure of loudspeaker warner in the box).Press the input code knob,, press the knob that locks, make controller be in the state of alert that locks with the password that the keyboard input is set; During release, only need to press password set on the lower keyboard, keyboard case is that an exportable unlocking signal is given control enclosure, make control signal of control enclosure circuit output, (low level) to the RESET input of signal output apparatus, makes its upset no-output that resets, the circuit release.When mistake connects keyboard password or not with PUK in the direct inlet chamber when (sensor is disconnected), the control enclosure circuit all can be triggered, the output alarm control signal.
Destroy controller in order to prevent the way of taking to cut off line, a terminal of the external sensor terminals on the utility model control enclosure is to be connected on the output terminal of keyboard case, like this, and when when cutting off connecting line outdoors, can make control circuit trigger the output alarm control signal equally.
Advantages such as the utility model has been owing to adopted keyboard password formula release circuit and designed the advanced reasonably control circuit with external alarm interface, and it is flexible and convenient to use to make that controller has, safe and reliable.
