Description of drawings
Fig. 1 is frame assumption diagram of the present utility model;
Fig. 2 is circuit theory diagrams of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1 and Figure 2, a kind of interconnection type anti-theft circuit of the present utility model, comprise light-operated sensing circuit 1 and single chip machine controlling circuit 2, the output signal of described light-operated sensing circuit 1 is transferred to trigger circuit 12 through composite amplifier 11, the output signal of described trigger circuit 12 is transported to single chip machine controlling circuit 2, and the output signal of described single chip machine controlling circuit 2 sends to ZigBee wireless module circuit 21, GSM short message receiving-transmitting circuit 22 and warning circuit 23.
Described light-operated sensing circuit 1 adopts silicon photocell EG as light control sensor, its specification is selected 2*2cm or also available two series connection uses for use, to increase output power, it is installed in the place of Chang Mingguang irradiation, described composite amplifier 11 is made of the first transistor T1 and transistor seconds T2, and the emitter of described the first transistor T1 is connected to transistor seconds T2 to base stage.In case next interim as the thief, the suffered light of silicon photocell EG easily is blocked again.Form mu balanced circuit by resistance R 2, voltage stabilizing diode DW, provide suitable operating voltage to silicon photocell EG, at ordinary times, illumination is arranged to silicon photocell EG, the anodal Weak current of silicon photocell EG is flowed out, after the first transistor T1 and the compound amplification of transistor seconds T2, make the 3rd transistor T 3 saturation conductions, the 5th transistor T 5, the 6th transistor T 6, the 7th transistor T 7 all are in and end, isolate the 37th end that the output low-potential signal sends to single-chip microcomputer IC1 through diode D, after the comprehensive judgement of single-chip microcomputer IC1, do not send control signal.
In case the thief flashes, silicon photocell EG light is blocked, the first transistor T1 and transistor seconds T2, the 3rd transistor T 3 all ends, pressure drop is almost 0V on resistance R 4, the 4th transistor T 4 ends, the 5th then conducting of transistor T 5T5, noble potential charges to capacitor C 1 through the 5th transistor T 5 and the c-e utmost point, when capacitor C 1 both end voltage 1.4V is above, the 6th transistor T 6,7 conductings of the 7th transistor T, isolate the 37th end that the output high potential signal is sent to single-chip microcomputer IC1 through diode D, after the comprehensive judgement of single-chip microcomputer IC1 internal processes, divide three the tunnel to send control signal, first via output is by the 7th of single-chip microcomputer IC1,8,27,28 form the data transmission telecommunication circuit with GSM short message transceiving module IC3, and IC1 sends data command by single-chip microcomputer, drive GSM short message transceiving module IC3 and send SMS alarm information to the personnel of the control center mobile phone of appointment, show current warning address, information such as orientation.The second tunnel output, the 2nd pin output low level of single-chip microcomputer IC1 makes news Chinese percussion instrument B send the alarm sound.Third Road output, form ZigBee wireless module circuit 21 by the 6th, 7 ends of ZM2410 wireless communication module IC2 and the 10th, 11 ends of single-chip microcomputer IC1 etc., ZM2410 wireless communication module IC2 is the embedded serial ports transparent transmission of the Zigbee of built-in 2.4GHZ (some multiple spot and point-to-multipoint) communications protocol, supports aerial upgrade firmware or configuration far module information.Up to the output of the power of 7dBm and-receiving sensitivity of 100dBm, can satisfy telecommunication, send the AT instruction by single-chip microcomputer IC1 ZM2410 wireless communication module IC2 is realized wireless data transceiving, switch pin with the RS-485 direction, drive the ZigBee wireless module and send warning message to the duty alarm center, have advantages such as networking is simple, cost is low, rate of false alarm is low, transmission information is fast.
