Abstract
The utility model relates to a joint-defense alarm with anti-theft function, which comprises a plurality of alarms, each alarm is provided with an unique mark, an alarming button is arranged on the alarm, when the alarming button is pressed down or the alarm receives the remote alarming from the remote controller, a processor built in the alarm actuates the horn to give an alarm, and then send the alarming signals with the mark to peripheral alarms by wireless communication, the alarm also comprises a circuit- breaking alarming circuit and a pair of input terminals, one end of the input terminals is connected into the circuit-breaking alarming circuit, when the input terminals are circuit-opened, the circuit-breaking alarming circuit actuates the processor to drive the horn to give an alarm. The utility model adds the circuit-breaking alarming circuit on the base of the joint defense alarming, when the input terminals are circuit-opened, the alarming circuit is to actuate the processor to give an alarm, thereby reaching the purpose of anti-theft.
Description
Technical field
The utility model relates to alarm, relates in particular to a kind of joint defence alarm with anti-theft feature.
Background technology
The alarm that existing joint defence alarm is reported to the police by a plurality of communications is mutually formed, and the alarm button of alarm on being subjected to telecontrol or alarm sends the warning that pipes when being pressed, and alerting signal is passed to the alarm of periphery, plays joint defence warning effect.But this joint defence alarm only can send warning under artificial control, and owner not or the not found situation of thief under, can not get effective anti-theft protection.
The utility model content
The utility model provides a kind of joint defence alarm with anti-theft feature at the above-mentioned defective of prior art.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
A kind of joint defence alarm with anti-theft feature, comprise a plurality of alarms, each alarm has unique sign, alarm is provided with alarm button, the built-in processor of alarm triggered the loudspeaker warning that pipes when the telepilot tele-alarm is pressed or received to the alarm button, and send alerting signal to peripheral alarm with this alarm sign by radio, described alarm also comprises breaking alarming circuit and pair of input terminals, this is connected to the breaking alarming circuit to input terminal one end, when this opened circuit to input terminal, breaking alarming circuit triggers processor drove the loudspeaker warning that pipes.
Preferably, described breaking alarming circuit comprises the detecting unit that opens circuit, voltage comparison unit, reference voltage unit; The detecting unit that opens circuit is connected with input terminal, and the voltage signal that output detects is to voltage comparison unit, to the open circuit voltage signal of detecting unit output and the voltage comparative analysis of reference voltage unit of voltage comparison unit exports processor then to, the voltage comparison unit output abnormality is as a result the time, and processor triggers loudspeaker and reports to the police.
As can be seen from the above technical solutions, the utility model is set up the breaking alarming circuit on the basis that joint defence is reported to the police, and when input terminal opened circuit, warning circuit triggered the processor of reporting to the police and reports to the police, and reaches antitheft purpose.
Description of drawings
Accompanying drawing is the utility model schematic block circuit diagram.
Embodiment
Below in conjunction with embodiment the new breaking alarming circuit type of this practicality is described in further detail.
The utility model joint defence alarm, comprise a plurality of alarms, each alarm has unique sign, alarm is provided with alarm button, the built-in processor of alarm triggered the loudspeaker warning that pipes when the telepilot tele-alarm is pressed or received to the alarm button, and send alerting signal to peripheral alarm with this alarm sign by radio, described alarm also comprises breaking alarming circuit and pair of input terminals, this is connected to the breaking alarming circuit to input terminal one end, when this opened circuit to input terminal, breaking alarming circuit triggers processor drove the loudspeaker warning that pipes.
Participate in shown in the accompanying drawing, the utility model breaking alarming circuit theory is described: cut-offing alarming circuit 2 comprises voltage comparison unit 21, outage detection unit 22, reference voltage 23, input terminal 24, outage detection unit 22 constitutes the loop with input terminal 24, access state to input terminal 24 detects, and detected voltage signal is transported to voltage comparison unit 21, voltage comparison unit compares analysis with the voltage signal of outage detection unit 22 conveyings and the voltage signal of reference voltage 23, when comparative result is unusual, triggers processor 1 and drive loudspeaker 3 warning that pipes.
The utility model using method is as follows: insert lead at the input terminal two ends, lead passes the article of desire protection, turns on the power switch to make outage detection unit 22 in running order.When the thief scrounges, must take away thing, cause the lead that inserts the terminal two ends to be pulled apart like this, make input terminal be in off state, detecting unit detects this state, produces change in voltage, the voltage of this variation is outputed to voltage comparison unit, voltage comparison unit compares itself and reference voltage, draws abnormal results, drives the loudspeaker warning thereby trigger processor.
The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
Claims (2)
1, a kind of joint defence alarm with anti-theft feature, comprise a plurality of alarms, each alarm has unique sign, alarm is provided with alarm button, the built-in processor of alarm triggered the loudspeaker warning that pipes when the telepilot tele-alarm is pressed or received to the alarm button, and send alerting signal to peripheral alarm with this alarm sign by radio, it is characterized in that: described alarm also comprises breaking alarming circuit and pair of input terminals, this is connected to the breaking alarming circuit to input terminal one end, when this opened circuit to input terminal, breaking alarming circuit triggers processor drove the loudspeaker warning that pipes.
2, the joint defence alarm with anti-theft feature according to claim 1 is characterized in that: described breaking alarming circuit comprises the detecting unit that opens circuit, voltage comparison unit, reference voltage unit; The detecting unit that opens circuit is connected with input terminal, and the voltage signal that output detects is to voltage comparison unit, to the open circuit voltage signal of detecting unit output and the voltage comparative analysis of reference voltage unit of voltage comparison unit exports processor then to, the voltage comparison unit output abnormality is as a result the time, and processor triggers loudspeaker and reports to the police.
