Embodiment
Below in conjunction with accompanying drawing and specific embodiment technical scheme according to the invention is done further to describe in detail so that those skilled in the art can better understand the present invention and can implement, but the embodiment that lifts not conduct to qualification of the present invention.
According to one embodiment of the invention, it provides a kind of fixedly article anti-theft device 100 based on Internet of Things, and is as shown in Figure 1, and it comprises power module 5, PMU 3, acceleration transducer 4, control module 1, and transmission unit 2, wherein,
PMU 3 is managed in order to the electric energy that said power module 5 is carried, and respectively to said acceleration transducer 4, control module 1, and transmission unit 2 provides electric energy.
When acceleration transducer 4, acceleration transducer 4 collect the acceleration information of monitored fixedly article, wake control module 1 up, and send said acceleration information to said control module 1.In this embodiment of the present invention, what said acceleration transducer 4 adopted is the MMA8452 acceleration transducer of Freescale, and it is a the have intelligent low-power consumption of 12 bit resolutions, three, capacitance type micro mechanical acceleration transducer 4.Because this acceleration transducer 4 has abundant embedded functional, and has user-programmable option flexibly, can dispose nearly two interrupt pin.Embedded interrupt function can be saved the overall power of control module 1; Removing said control module 1 needs the burden of continuous poll acceleration information; In the present embodiment; When said acceleration transducer 4 collects the acceleration information of monitored fixedly article, produce look-at-me and be sent to control module 1, thereby wake this control module 1 up.In addition; The technician in present technique field is not difficult to expect; Said acceleration transducer 4 can also adopt the acceleration transducer 4 of other models of other companies, and present embodiment is only explained the function of said acceleration transducer 4, not in order to limit the type of this acceleration transducer 4.
Under the preferred implementation; Said PMU 3 comprises LDO module 31 and DC-DC module 32; The input end of said LDO module 31 is connected to said power module 5; Its output terminal is connected to said acceleration transducer 4 and control module 1, and the input end of said DC-DC module 32 is connected to said power module 5, and its output terminal is connected to said transmission unit 2.For said DC-DC module 32, in the present embodiment, it adopts the DC-DC Switching Power Supply TPS54620 chip of TI company to design; The current sinking of chip itself is lower than 10uA, and efficient is high, and output current can reach 6A; In order to supply power to said transmission unit 2, the peripheral circuit of this DC-DC module 32 is comparatively simple, only needs less resistance, electric capacity; And an external power inductance, and do not need external fly-wheel diode, just can the less burning voltage of output ripple.Simultaneously; It has the control end of enabling, and when transmission unit 2 need not guarded against theft the transmission of warning information, control module 1 can be controlled this and enable control end; Make that the output voltage of 32 pairs of these transmission units 2 of this DC-DC module is zero, thereby reach the purpose that reduces power consumption.For said LDO module 31, in the present embodiment, its voltage to 5 inputs of said power module carries out step-down to be handled, and is 3.3V to the voltage swing of said acceleration transducer 4 and control module 1 output.Because the static current of lcd of control module 1 is lower, therefore in practical application, adopt the LDO step-down design of low quiescent current, for example, the chip of said LDO module 31 can be selected the TLV70433 chip of TI company.
In a preferred implementation of the embodiment of the invention, as shown in Figure 2, said transmission unit 2 comprises controller 21, RF transceiver 22, wave filter 23, power amplifier 24 and Anneta module 25, wherein,
In practical application; Displacement duration information, the displacement alarm threshold information of being stored for control module 1 in the said anti-theft device 100, and hereinafter will set forth can set through Surveillance center 200 and send it to this anti-theft device 100 by the user by user's pre-set time interval information, number threshold information or the like through the Internet of Things agreement.
The embodiment of the invention also provides a kind of fixedly article burglary-resisting system based on Internet of Things; As shown in Figure 3; This burglary-resisting system comprises at least one aforesaid anti-theft device 100, and carries out the Surveillance center 200 of information interaction through Internet of Things agreement and said anti-theft device 100.
In the practical implementation process; Said anti-theft device 100 is arranged on the monitored fixedly article; When said fixedly when stolen situation takes place article; Because said anti-theft device 100 is provided with acceleration transducer 4, and cooperates the fixedly antitheft method of article based on Internet of Things provided by the invention, it can be timely with the warning information of guarding against theft to user feedback; The mode of said feedback comprises that Surveillance center 200 sends note, multimedia message or directly calls to user mobile phone or other portable terminal devices, thereby informs the generation of its these robber's feelings in real time.Preferably, the information interaction between said Surveillance center 200 and the said anti-theft device 100 adopts the Internet of Things agreement, and for example said Internet of Things agreement is a WMMP Internet of Things interaction protocol.
The embodiment of the invention also provides a kind of fixedly antitheft method of article based on Internet of Things; Continuation is with reference to Fig. 1; Its anti-theft device 100 comprises power module 5, PMU 3, acceleration transducer 4, control module 1; And transmission unit 2, as shown in Figure 4, said fixedly antitheft method of article based on Internet of Things comprises:
