Abstract

The utility model discloses a burglar alarm. The burglar alarm is characterized in that the burglar alarm comprises a pressure sensor used for detecting pressure of human bodies, an A/D converter used for receiving human body signals and converting the human body signals into digital signals and a control circuit communication module used for receiving the digital signals and sending alarm instructions; wherein the input terminal of the A/D converter is connected with the pressure sensor, and the output terminal of the A/D converter is connected with the control circuit communication module. By employing the burglar alarm, even if users are not at home, the users can get stealing alarm information through a wireless module; by employing the pressure sensor to detect pressure signals, the false alarm rate is low; by employing a one-chip microcomputer as a master control module, the control circuit is simple in structure and high in reliability; and by employing a GSM communication module, the users can receive alarm information as long as mobile phone signals exist.

Description

A kind of burglar alarm

Technical field

The utility model relates to a kind of burglar alarm.

Background technology

Now, often have family the theft phenomenon occurs, and some residential quarters security personnel's strength imperfection.Burglar alarm is also arranged in the market, but major part only has sound caution, can't remote alarms; Some complex structures, cost is high; And often someone walks about due to general house, adopts the alarm of vibration transducer, rate of false alarm is also high.

The utility model content

The utility model purpose is for the deficiencies in the prior art, provides a kind of and can find in time intruder the burglar alarm of reporting to the police.

The utility model for achieving the above object, adopts following technical scheme:

A kind of burglar alarm, is characterized in that, described burglar alarm comprises: for detection of human pressure's pressure transducer; For receiving the A/D converter that human body signal is converted to digital signal; For the control circuit communication module of the concurrent alert instruction of delivering newspaper of receiving digital signals, the input end Bonding pressure sensor of wherein said A/D converter, the output terminal of described A/D converter connects the control circuit communication module.

It is further characterized in that, described control circuit communication module comprises for receiving digital signals and sends the single chip machine controlling circuit of instruction; For receiving the GSM communication module of the concurrent alert enlightenment of delivering newspaper of instruction, the input end of described single chip machine controlling circuit connects A/D converter, and the output terminal of described single chip machine controlling circuit connects the GSM communication module.

It is further characterized in that, described burglar alarm also comprises that described electric battery is connected successively with hand switch for electric battery and the hand switch of power supply, and the output terminal of described hand switch connects the input end of single chip machine controlling circuit.

Compared with prior art, burglar alarm of the present utility model, even, in the user stays out, also can learn stolen warning message by wireless module; Adopts pressure sensor detected pressures signal, rate of false alarm is low; Adopt single-chip microcomputer as main control module, make control circuit simple in structure, reliability is high; Adopt the GSM communication module, as long as the place of mobile phone signal is arranged, user's information that just can receive the report for police service.

The accompanying drawing explanation

Fig. 1 is the utility model structural representation;

Wherein: 1, electric battery; 2, switch; 3, pressure transducer; 4, A/D converter; 5, single chip machine controlling circuit; 6, GSM communication module.

Embodiment

A kind of burglar alarm as shown in Figure 1, this burglar alarm be by electric battery 1, hand switch 2, and pressure transducer 3, A/D converter 4, single chip machine controlling circuit 5, GSM communication module 6 forms.

When the user pressed hand switch 2, electric battery 1 was to single chip machine controlling circuit 5 power supplies, and after single chip machine controlling circuit 5 initialization, warning system enters holding state.

The pressure transducer of alarm 3 is placed under the introduction foot pad, when having the people to swarm into the pressure transducer 3 that steps down in doorway, pressure transducer 3 detects backward single chip machine controlling circuit 5 transmitted signals of pressure, after single chip machine controlling circuit 5 receives signal, to GSM communication module 6, send instruction, GSM communication module 6 sends alarming short message according to program to default mobile phone and infrastructure management company, plays alarm function.

The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
