Abstract

The utility model relates to a security and protection short message alarm module comprising an infrared signal acquisition circuit, a single chip microcomputer control circuit and a GSM module circuit. The output signal of the infrared signal acquisition circuit is transmitted to a comparator circuit through an amplifier circuit. The output signal of the comparator circuit is sent to the GSM module circuit through the single chip microcomputer control circuit. When a human signal is acquired by the infrared signal acquisition circuit, according to the utility model, the signal is amplified, compared and processed, and then judgment is performed by the single chip microcomputer control circuit, and the GSM module circuit is driven to send alarm information to the phone number of a designated person, so the security and protection short message alarm module is a new generation of wireless transmission alarm device having advantages of simple networking and reliable performance.

Description

A kind of security protection short message alarm module
Technical field
The utility model relates to electronic circuit field, particularly be a kind of security protection short message alarm module.
Background technology
Traditional security alarm circuit is most adopts wired or wireless mode to report to the police, and has the short or networking of the alarm distance shortcomings such as inconvenient, cost is high, unstable properties of reporting to the police.
Utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of security protection short message alarm module is provided.
The utility model solves the technical scheme that its technical matters adopts: a kind of security protection short message alarm module, include infrared signal Acquisition Circuit, single chip machine controlling circuit and gsm module circuit, the output signal of described infrared signal Acquisition Circuit is transferred to comparator circuit through amplifier circuit, and the output signal of described comparator circuit is sent to gsm module circuit through single chip machine controlling circuit.
Described infrared signal Acquisition Circuit adopts infrared sensor BH to gather human body signal.
Described single chip machine controlling circuit adopts 2051 single-chip microcomputer IC1.
By adopting above-mentioned technical scheme, the beneficial effects of the utility model are: in the time that infrared signal Acquisition Circuit collects human body signal, the utility model is after signal amplifies, relatively processes, judged by single chip machine controlling circuit, driving gsm module circuit to send warning message to designated person's phone number, is that networking is simple, the new generation of wireless of dependable performance transmission warning device.
Brief description of the drawings
Fig. 1 is frame assumption diagram of the present utility model;
Fig. 2 is circuit theory diagrams of the present utility model.
Embodiment
Further illustrate the utility model below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, a kind of security protection short message alarm module of the present utility model, include infrared signal Acquisition Circuit, single chip machine controlling circuit and gsm module circuit, the output signal of described infrared signal Acquisition Circuit is transferred to comparator circuit through amplifier circuit, and the output signal of described comparator circuit is sent to gsm module circuit through single chip machine controlling circuit.
As shown in Figure 2, described infrared signal Acquisition Circuit adopts infrared sensor BH to gather human body signal, infrared sensor BH can detect the faint infrared ray that human motion sends in larger distance, when infrared sensor BH detect human motion send infrared signal time, through being converted into low frequency electric signal, output to the first operational amplifier IC2/A by the 2nd pin of infrared sensor BH and amplify, be then coupled to the second operational amplifier IC2/B by the output terminal of the first operational amplifier IC2/A through capacitor C 7 signal is done further to amplify.
The 3rd operational amplifier IC2/C and four-operational amplifier IC2/D form voltage comparator, when the 3rd operational amplifier IC2/C and four-operational amplifier IC2/D output high level, it is respectively through diode VD6, VD7 isolates the effect of (positive or gate) mutually, export high level signal through resistance R 12 again, be input to the 18th pin I/O end of 2051 single-chip microcomputer IC1, also be high level state, through 2051 single-chip microcomputer IC1 inter-process and be judged as unauthorized person invasion, send control signal, the gsm module IC3 being connected by the 11st pin output terminal of 2051 single-chip microcomputer IC1, send driving signal by 2051 single-chip microcomputer IC1 to IC3, after the decoding of gsm module IC3 internal circuit, transmit through base station network, phone number to designated person sends warning message, notify in time security personnel to reach the spot, there is removable installation, network alarm is convenient, the advantages such as communication alarm distance is far away.
Above-described is only a preferred embodiment of the present utility model, can not limit the scope that the utility model is implemented, and every equalization of doing according to the utility model claim changes and decorates, and all should still belong in the scope that the utility model contains.
