Embodiment

This invention comprises acceleration sensor module, intelligent control module, alarm module, power module and wireless module.When the notebook user leaves notebook, this invention can be fixed on the antitheft lockhole of its notebook, and open switch.At this moment, the user can be made as the burglar alarm state with this anti-theft device by mobile phone.If remove anti-theft state, the password that needs input to configure.When the burglar alarm state, if someone touches notebook computer, the acceleration transducer of this invention will be caught abnormality, under the control of intelligent control module, drive alarm module and carry out this locality warning, control wireless module simultaneously, wireless module will be put through user's mobile phone by the GSM network this moment, remind the user and will realize the purpose that notebook is antitheft thereby reach.

The power module of this invention adopts powered battery, and battery case is located with screw-socket, makes stealer be difficult to take out power supply from this invention in the very short time.

The structured flowchart of total system as shown in Figure 2.The principle of work of acceleration transducer is that acceleration signal is converted into the output aanalogvoltage.The output aanalogvoltage is by A/D (digital-to-analog conversion) back input intelligent control module.Intelligent control module can adopt DSP (digital signal processor), ARM (Advanced RISC Machines) or singlechip chip and peripheral circuit thereof to constitute.Adopting MMA6260 chip, intelligent control module to adopt the MSP430F149 single-chip microcomputer with acceleration sensor module below is example, carries out feasibility analysis.

Acceleration transducer and one-chip machine common 3.3V power supply, according to the acceleration transducer characteristic, output voltage range is 0.25V~3.05V, output voltage enters the Chip Microcomputer A passage and carries out analog to digital conversion.The inner ADC of single-chip microcomputer needs a reference signal, is generally voltage reference, and the numeral output expression analog input of ADC is with respect to the ratio of its benchmark.If N ADCBe the numeral output of ADC, V R+, V R-Be reference voltage, then have:

N ADC = 4095 × V in - V R - V R + - V R -

V among the present invention R+Be made as V CC, V R-Be made as V SSSo, when it when directions X does not have acceleration, output voltage should be 1.65V, and institute's total should be 1000,0000,0000 behind the Chip Microcomputer A C.

If the numeral that directions X transforms is output as N X, the numeral that the Y direction transforms is output as N Y, minimum warning acceleration equivalence numeral is output as N Th, then have:

N in the formula ThCan set by repeatedly testing.N ThExcessive, then do not have antitheft effect; N ThToo small, then false-alarm probability is bigger.

AD resolution is 12, and according to MSP430F149 Chip Microcomputer A/D conversion characteristic as can be known, it has the 2bit transformed error, promptly ± and 2LSB.So conversion accuracy is:

(3.3/4096)×4=3.2mV

The sensitivity of MMA6260 is 800mV/g, so theoretical precision is:

3.2mV/(800mV/g)=0.004g。

As seen the theft-prevention applications requirement is satisfied in the sensitivity of this invention.
