Description

Wireless anti-theft equipment

Technical field

The utility model relates to antitheft field, particularly be a kind of wireless anti-theft equipment.

[background technology]

Traditional anti-theft circuit, most employing infrared induction circuit, but use in the place that personnel often come in and go out, rate of false alarm is high.。

[utility model content]

In order to overcome above shortcomings part in prior art, the purpose of this utility model is to provide a kind of wireless anti-theft equipment.

In order to reach above-mentioned object, the utility model adopts following concrete technical scheme: wireless anti-theft equipment, include light-operated sensing circuit, single chip machine controlling circuit, ZigBee wireless module circuit and linkage circuit, the output signal of described light-operated sensing circuit is transferred to trigger circuit through composite amplifier, the output signal of described trigger circuit is sent to single chip machine controlling circuit, and the output signal of described single chip machine controlling circuit is sent to ZigBee wireless module circuit and linkage circuit respectively.

Described light-operated sensing circuit irradiates local silicon photocell EG collection signal by being arranged on Chang Mingguang.

Described single chip machine controlling circuit adopts 2051 single-chip microcomputer ICl.

Described ZigBee wireless module circuit adopts zM2410 wireless module IC2.

The utility model advantage is compared with prior art: the utility model adopts light-operated sensing circuit, can monitor specific public domain, when unauthorized person enters into this region, by zigBee wireless module circuit sending signal, when data warning receive centre is to alerting signal, the warning messages such as orientation, display alarm address, have networking simple, adopt the integrated networking of honeycomb fashion, cost is low, compatibility is strong, is widely used in machine room, illumination coordinated signals opertaing device, has anti-theft feature.

[accompanying drawing explanation]

Fig. 1 is frame assumption diagram of the present utility model;

Fig. 2 is circuit theory diagrams of the present utility model;

Below in conjunction with accompanying drawing, the utility model is described in further detail.

[embodiment]

In order to explain the technical solution of the utility model further, below by specific embodiment, the utility model is elaborated.

As shown in Figure 1, wireless anti-theft equipment of the present utility model, include light-operated sensing circuit, single chip machine controlling circuit, ZigBee wireless module circuit and linkage circuit, the output signal of described light-operated sensing circuit is transferred to trigger circuit through composite amplifier, the output signal of described trigger circuit is sent to single chip machine controlling circuit, and the output signal of described single chip machine controlling circuit is sent to zigBee wireless module circuit and linkage circuit respectively.

As shown in Figure 2, described light-operated sensing circuit irradiates local silicon photocell by being arranged on Chang Mingguang: EG collection signal, its specification is selected 2*2cm or also can be used with two panels series connection, to increase output power, when once thief comes interim, silicon photocell: EG institute light is easily blocked again, by resistance R2, voltage stabilizing diode DW forms mu balanced circuit, to silicon photocell: EG provides applicable operating voltage, at ordinary times, there is illumination on silicon photocell EGr, silicon photocell EGr positive pole Weak current is flowed out, through the first transistor T1, after transistor seconds T2 compound is amplified, make third transistor T3 saturation conduction, 5th transistor T5 ~ the 7th transistor T7 is all in cut-off, through the 19th end of diode D1 isolation and amplifier low-potential signal to 2051 single-chip microcomputer ICl, after 2051 single-chip microcomputer ICl comprehensive descision, do not send control signal.

Once thief flashes, silicon photocell EG light is blocked, the first transistor T1, transistor seconds T2, third transistor T3 all ends, on resistance R4, pressure drop is almost 0V, 4th transistor T4 ends, 5th transistor T5 then conducting, noble potential charges to electric capacity C1 through the c-e pole of the 5th transistor T5, during electric capacity more than C1 both end voltage 1.4V, 6th transistor T6, 7th transistor T7 complex pipe conducting, through the 19th end of diode D1 isolation and amplifier high potential signal to 2051 single-chip microcomputer ICl, after 2051 single-chip microcomputer ICl internal processes comprehensive descision, two-way is divided to send control signal, the first via exports, high level is exported by the 14th pin of 2051 single-chip microcomputer ICl, through resistance R11 current limliting, make the 8th transistor T8 conducting, relay J adhesive, the contact J-1 of relay J transfers normally closed point to, link other equipment.Another road exports by the 6th of ZM2410 wireless module IC2, the 2nd of 7 ends and 2051 single-chip microcomputer ICl, 3 end composition ZigBee wireless module circuit, 2051 single-chip microcomputer ICl are the embedded serial ports transparent transmission of zigbee (some multiple spot and the point-to-multipoint) communications protocol of built-in 2.4GHZ, support aerial upgrade firmware or configuration far module information, up to the power stage of 7dBm and the receiving sensitivity of-100dBm, telecommunication can be met, send AT instruction by 2051 single-chip microcomputer ICl and wireless data transceiving is realized to ZM2410 wireless module IC2, pin is switched with RS-485 direction, current failure information is sent to data center, the utility model is honeycomb fashion networking, reach distance, low cost and other advantages, be widely used in machine room, illumination coordinated signals opertaing device, there is anti-theft feature.

But above-mentioned embodiment is exemplary, being to better enable those skilled in the art understand this patent, can not being interpreted as it is restriction this patent being comprised to scope; As long as according to this patent disclose any equivalent change done or the modification of spirit, all fall into the scope that this patent comprises.
