Description

GSM multimedia message alarm monitor

Technical field

The utility model relates to the watch-dog field, particularly relates to a kind of GSM multimedia message alarm monitor.

Background technology

In some important events, need to adopt watch-dog antitheft because of unattended, and major part all only adopt easy anti-theft device, this anti-theft device only acts on onsite alarming, does not have evidence but steal, and solves a case to public security organ and has caused a lot of inconvenience.

The utility model content

The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of GSM multimedia message alarm monitor is provided.

The technical scheme that the utility model adopted is such: GSM multimedia message alarm monitor, comprise human body sensing trigger circuit and single chip machine controlling circuit, described human body sensing trigger circuit are made up of the output terminal connection infrared sensor IC4 of induced electricity pole piece TX, described infrared sensor IC4 output connects the pierce circuit of being made up of triode Q1 and switching tube Q2, the emitter output terminal of switching tube Q2 is connected to the I/O input end of single-chip microcomputer IC1, divide three tunnel control outputs through the computing of single-chip microcomputer IC1 internal processes, the first via is connected to audio alert chip IC 2 by the level signal of single-chip microcomputer IC1 output through triode Q4, audio alert chip IC 2 is coupled to audio frequency integrated amplifier chip IC 3 through capacitor C 6, audio frequency integrated amplifier chip IC 3 output control loudspeaker Y; The level signal of secondary route single-chip microcomputer IC1 output is connected to relay J 1 through triode Q3, by normal open switch J1-1 controlling and driving lighting circuit; Third Road is formed communication control circuit by single-chip microcomputer IC1 and GSM multimedia message short message transceiving module U1.

Described infrared sensor IC4 adopts the RD627 infrared sensor.

By adopting the aforementioned techniques scheme, the beneficial effects of the utility model are: when human body enters monitored space, send drive signal by single-chip microcomputer to modular circuit, and send alerting signal to the designated person by GSM multimedia message short message transceiving module, deposit mobile phone in by the multimedia message of designated person's reading images, stay evidence material, help in time handling the pilferage behavior and solve a case rapidly.

Description of drawings

Fig. 1 is the circuit theory diagrams of the utility model embodiment.

Embodiment

Further specify the utility model below in conjunction with the drawings and specific embodiments.

As shown in Figure 1, GSM multimedia message alarm monitor, comprise human body sensing trigger circuit and single chip machine controlling circuit, described human body sensing trigger circuit are made up of the output terminal connection RD627 infrared sensor IC4 of induced electricity pole piece TX, described RD627 infrared sensor IC4 output connects the pierce circuit of being made up of triode Q1 and switching tube Q2, the emitter output terminal of switching tube Q2 is connected to the I/O input end of single-chip microcomputer IC1, when near the induced electricity pole piece TX nobody the time, triode Q1 and switching tube Q2 all are in cut-off state, 6 pin of RD627 infrared sensor IC4 are low level, A point current potential also is an electronegative potential, single-chip microcomputer IC1 internal control program does not have any output, and illustrating does not have human body near guarded region.As human body when the induced electricity pole piece TX, the oscillator oscillatory work, emitter outputting oscillation signal from triode Q1, this oscillator signal is through semiconductor diode D rectification, make switching tube Q2 conducting, the 2nd pin of RD627 infrared sensor IC4 becomes low level by high level, the 6th pin of RD627 infrared sensor IC4 becomes high level by low level, this moment, A point current potential also was input to the 3rd pin I/O end of single-chip microcomputer IC1 for noble potential, divide three tunnel outputs through the computing of single-chip microcomputer IC1 internal processes, the first via is exported high level signal through resistance R 8 current limlitings from the 2nd pin of single-chip microcomputer IC1, make triode Q4 enter conducting state, therefore audio alert chip IC 2 obtains supply voltage, the 2nd pin of audio alert chip IC 2 output audio alert signal is coupled to the 3rd pin of LM386 audio frequency integrated amplifier chip IC 3 through capacitor C 6, after its internal audio frequency amplifies, again by its 6th pin output terminal after capacitor C 7 coupling is amplified, promote loudspeaker Y and send alert sound; The 21st pin output high level signal of secondary route single-chip microcomputer IC1 makes triode Q3 conducting through resistance R 9 current limlitings, makes relay J 1 adhesive, and normal open switch J1-1 makes power for illumination rood electricity by becoming normally closed point normal battle simultaneously, opens floodlighting and allows stealer leave; Third Road is by the 12nd of single-chip microcomputer IC1 the, 6,8,1 end and GSM multimedia message short message transceiving module U1 form communication control circuit, when single-chip microcomputer IC1 detects A point current potential and is high level state, after its internal control is handled, U1 sends steering order to GSM multimedia message short message transceiving module, send the multimedia message warning message by inner SIM card of GSM multimedia message short message transceiving module U1 and integrated circuit to the master cellular phone number of appointment, owner is correspondingly processed after receiving, and by resistance R 1-R4, button K1-K6 forms the keyboard operation circuit, be used for self check, reset, the police that disappears waits the setting of switching function, and this function is finished by the setting of IC1 internal processes.

More than show and described ultimate principle of the present utility model and principal character and advantage thereof; the technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the explanation just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications; these changes and improvements all fall in claimed the utility model scope, and the claimed scope of the utility model is defined by appending claims and equivalent thereof.
