The device is convenient to use and is easy to install and popularize.
Description
Technical field
The utility model relates to the wireless data transmission field, especially a kind of burglar alarm.
Background technology
At people's home environment safety problem, produced a lot of burglar alarms at present, and molded coming into operation.Yet there are some hidden danger in present anti-theft device aspect intelligent and the security.Many times, very first time realization is real-time transmitted to the user with warning message, is that the household anti-theft device is very paid close attention to.Therefore, the burglar alarm of taking into account intelligent and hommization and real-time is the core emphasis that designs.For this reason, need a kind of novel anti-theft warning device of design.
Summary of the invention
Technical problem to be solved in the utility model is at disadvantages of background technology, and a kind of home furnishings intelligent burglar alarm is provided.
The utility model adopts following technical scheme for solving the problems of the technologies described above:
A kind of burglar alarm comprises power module, infrared detection alarm module, sets up defences and separate anti-module, single-chip microcomputer, GSM communication module, user mobile phone;
Wherein, described power module is used to realize the power supply of whole device;
Described infrared detection alarm module is used to realize the detection and the alarm of domestic environment;
Described setting up defences separated the switching that anti-module is used to realize the state of deploying troops on garrison duty and withdraw a garrison of burglar alarm;
Described single-chip microcomputer is used to handle the infrared detection alarm module, sets up defences and separate the signal of anti-module;
Described GSM communication module is used for the alerting signal that single-chip microcomputer sends is transferred to user mobile phone.
Further, burglar alarm of the present utility model, the power module lead-acid accumulator power supply in support that also adopts 12V/7AH.
Further, burglar alarm of the present utility model, the infrared detection alarm module is made up of theft-proof sensor, signal processing circuit harmony photoelectric alarm.
Further, burglar alarm of the present utility model, theft-proof sensor adopt active infra-red correlation sensor; Signal processing circuit adopts operational amplifier, cooperation peripheral circuit to form the amplifying circuit with bandpass filter function the signal that collects is handled; The acousto-optic electric alarms based on pattern recognition is used for sending warning when detecting abnormal conditions.
Further, burglar alarm of the present utility model, GSM communication module have adopted the TC35i module of Siemens TC35 series.
The utility model has the advantages that and install simply, easy to use, be easy to promote.
Description of drawings
Fig. 1 is a principle schematic of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is done further introduction in detail:
As shown in Figure 1, the utility model includes power module, infrared detection alarm module, GSM communication module, sets up defences and separate anti-module, single-chip microcomputer and user mobile phone.
Voltage module is realized the power supply of whole device.Just often system adopts civilian Alternating Current Power Supply, but in order to prevent burglar's supply and AC dump with device before entering the defence area, the lead-acid accumulator of this device employing 12V/7AH is power supply in support.
Infrared detection alarm module infrared detection alarm module is made up of theft-proof sensor, signal processing circuit harmony photoelectric alarm.Theft-proof sensor adopts active infra-red correlation sensor.Just heat outputting electric signal after theft-proof sensor monitors the infrared ray that human body sends, because this signal is very faint and be mingled with undesired signal, therefore design special signal processing circuit and (adopted operational amplifier, the amplifying circuit that cooperates peripheral circuit formation to have bandpass filter function) isolates pyroelectric signal, and with thousands of times of its amplifications, by optimum Design of Parameters, cooperate comparator circuit further to eliminate the interference that the hot-air that flows causes.Then two-stage is amplified the isolated pyroelectric signal in back and carry out analysis and judgement.Be false action-proof, signal will compare with threshold level, produce high level signal output.The signal that difference probe is produced is incorporated into the INT1 mouth of single-chip microcomputer by rejection gate at last, and wait to interrupt to carry out corresponding action: when not interrupting, system is in holding state, can reduce system power dissipation like this.Send warning when detecting abnormal conditions acousto-optic electric alarms based on pattern recognition.
GSM communication module alert data transfer function, this module have been selected the TC35i of Siemens TC35 series for use.The TC35i module mainly is made up of 6 parts such as GSM baseband processor, GSM radio-frequency module, supply module, flash memory, ZIF connector, antennal interfaces.TC35i is compact to design, has dwindled small product size greatly, with the GSM2/2+ compatibility, supports double frequency (GSM 900/1800), has RS-232 data communication mouth, meets etsi standard GSM0707 and GSM0705, and is easy to upgrade to the GPRS module.This module integrates radio circuit and base band, provides the AT command interface of standard to the user, for data, voice, short message and fax provide quick, reliable, safe transmission, makes things convenient for the user to develop and designs.Work in series mode 1 is adopted in the communication of single-chip microcomputer and TC35i, and data layout is 10.Wherein, 1 start bit (0), 8 data bit (lowest order is preceding), 1 position of rest (1).The value of its baud rate depends on the flood rate of timer T1 and the value of the SMOD position among the special function register PCON.Because the TXD and the RXD level of single-chip microcomputer are Transistor-Transistor Logic level, and TC35i when carrying out communication through RS-232 interface, Transistor-Transistor Logic level and RS-232 level are incompatible, so during both interfaces, must carry out level conversion, use the MAX232 chip at this.
Set up defences and take over control module and adopt deploy troops on garrison duty and the withdraw a garrison switching of state of keyboard or mobile phone short messages to remotely control.In the system initialization process, in single-chip microcomputer, be provided with specific password.When the head of a family goes back home, can be by this password of correct input to withdraw a garrison.At this moment, will can not produce warning in indoor free activity.When going out, the operable key dish makes system reenter the state of setting up defences.
This device is installed simple, and is easy to use, and the real-time height is easy to promote, and can be widely used in the detection of home environment.
Disclosed arbitrary feature in this instructions is unless special narration all can be replaced by other equivalences or the alternative features with similar purpose.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
