Abstract

The utility model discloses an electronic burglar alarm which comprises a power, a checkout gear, a motion device and an alarm device, wherein the checkout gear is composed of a magnet which is arranged on the door and a tongue tube which is arranged on the doorframe, when the door is closed, the tongue tube clings to the magnet, the motion device is composed of a transistor, a biasing resistor and a relay, when the tongue tube is closed, the transistor is conducted, the relay is pulled in and the alarm device is a handset, when the relay is pulled in, the contactor of the relay accesses the switch of the handset and the handset sends out alarm signals to the prearranged telephone number. The electronic burglar alarm efficiently solves the problems of easy to damage, easy to make wrong alarms, robbers are easy to escape and the like, which are existed in normal burglar alarms, and the electronic burglar alarm has the advantages of simple structure, low manufacture cost, reaction sensitivity and high reliability, and the emote control burglar alarm is worth to be popularized and utilized.

Description

Electronic anti-theft alarm

Technical field

The utility model relates to a kind of burglar alarm, especially a kind of electronic anti-theft alarm that adopts mobile phone alarm.

Background technology

As everyone knows, alarm is the anti-thefting facility that current people generally use.Burglar alarm in the market, mostly be infrared ray, acoustic control and radar alarm, these alarms are mostly by audible alarm, and its microphone device is easy to destroyed and stops to report to the police, even microphone device is not destroyed, Deng near startling people the time, the robber makes an escape already, thereby makes the robber have idea of leaving things to chance, does not have antitheft effect truly.In addition, these burglar alarm sensitivity are too high, are subjected to the extraneous factor interference easily and cause wrong report, reported by mistake often, and people will produce decline in alertness, thereby make the robber that opportunity be arranged.

The utility model content

The utility model adopts the electronic anti-theft alarm of mobile phone alarm for the security hidden trouble that solves existing alarm existence provides a kind of safe and reliable.

The utility model is to reach the concrete technical scheme that above-mentioned technical purpose adopts to be: electronic anti-theft alarm is by power supply, pick-up unit, movement device and warning device are formed, pick-up unit is made up of with the tongue tube that is arranged on the doorframe the magnet that is arranged on the door, when door is closed, tongue tube is close to magnet, movement device is by transistor, biasing resistor and relay are formed, when tongue tube is closed, transistor turns, the relay adhesive, warning device is a mobile phone, during the relay adhesive, the contacting handset switch of relay, mobile phone sends alerting signal to the telephone number that sets in advance.Utilize magnet to control tongue tube, when door and window etc. was opened, tongue tube and magnet disengaged, the closed engage relay of tongue tube, by relay control handset switch, mobile phone just sends alerting signal to the telephone number that pre-sets, effective measures such as like this, owner can take to examine in the shortest time, warning, simultaneously since during mobile phone alarm without any sound, can not startle the robber, guarantee that the robber is caught, effectively play the safety precaution effect.

As preferably, the contact of tongue tube is a normally closed contact, uses normally closed contact can simplify circuit.

As preferably, electronic anti-theft alarm is provided with mobile phone supply line, and power supply is connected with the power circuit of mobile phone by voltage stabilizing diode.Like this, mobile phone can use cell panel, and electronic anti-theft alarm one edge work also can not use cell panel on one side to cell-phone charging, directly mobile phone is powered by electronic anti-theft alarm.

As preferably, electric power loop is provided with power switch, and when power switch was closed, electronic anti-theft alarm quit work.Someone the time, the powered-down switch, door and window can be opened or close normally, has avoided the false alarm of electronic anti-theft alarm.

The beneficial effects of the utility model are: it has solved being damaged easily of at present general burglar alarm existence, the problem that causes wrong report and robber to escape easily easily effectively.The utility model is simple in structure, and cost is low, is quick on the draw, and the reliability height is worthy of popularization.

Description of drawings

Below in conjunction with accompanying drawing embodiment of the present utility model is further described.

Fig. 1 is a kind of circuit theory diagrams of the utility model electronic anti-theft alarm.

Embodiment

Embodiment 1

In embodiment 1 as shown in Figure 1, electronic anti-theft alarm is made up of power supply, pick-up unit, movement device and warning device, and supply voltage is 12 volts, and its positive pole is in series with power switch S1.Pick-up unit is made up of with the tongue tube S2 that is arranged on the doorframe the magnet that is arranged on the door, and the contact of tongue tube S2 is a normally closed contact, the termination power positive pole of tongue tube S2, another termination movement device.Movement device is made up of transistor V1, biasing resistor R1 and relay K 1, the termination tongue tube S2 of biasing resistor R1, the base stage of another termination transistor V1, the collector of transistor V1 connects the positive pole of power supply, emitter is succeeded the line bag of electrical equipment K1, another termination power cathode of the line bag of relay K 1.Warning device is a mobile phone A 1, and the switch of mobile phone A 1 connects one group of normally open contact of relay K 1.Also be provided with mobile phone A 1 supply line on the electronic anti-theft alarm, the positive pole of power supply is connected with the positive pole of mobile phone A 1 by voltage stabilizing diode V2, and the negative pole of mobile phone A 1 is connected with the negative pole of power supply.

When owner goes out, turn on the power switch S1, close the doors and windows, this moment, tongue tube S2 was close to magnet, the normally closed contact open circuit of tongue tube S2, and transistor V1 ends, and relay K 1 line bag does not have electric current to flow through, and its contact disconnects, and mobile phone is in holding state.When door and window is opened, tongue tube S2 and magnet disengage, the normally closed contact closure of tongue tube S2, transistor V1 conducting, relay K 1 adhesive, during relay K 1 adhesive, the switch of the contacting mobile phone A 1 of relay K 1, mobile phone A 1 is sent alerting signal to the telephone number that sets in advance, and notifies the relevant personnel to adopt an effective measure.The people the time, as long as powered-down switch S 1, just can stop the work of electronic anti-theft alarm.
