Description
Technical field
The utility model relates to anti-theft tool, especially a kind of alarm utilizing step number to respond to alert trigger.
Background technology
Guard against theft and alarm system is by trigger alarm signals, notifies that owner or police process in time, plays deterrent effect to pilferage behavior.Existing warning system principle is complicated, and what have realizes distance alarm by bluetooth, but must have A, B end; What have utilizes gravity sensing, but uses inconvenience; Some volumes more greatly and do not have an aesthetic feeling and cannot carry with; The usable range limitation also had, install trouble, cost is high.
Utility model content
The applicant is for the shortcoming in above-mentioned existing production technology, and provide a kind of meter rational in infrastructure to walk induction alarm device, use the principle of work alert trigger signal of motion passometer thus play antitheft effect, cost is low, volume is little; Easy to use, be widely used.
The technical scheme that the utility model adopts is as follows:
A kind of meter step induction alarm device, comprise housing, described housing central section is provided with display screen, and described display screen top is loudspeaker, and the bottom of described display screen is provided with multiple function button, and the bottom of described function button is locking key; Described enclosure interior installs power supply, and described power output end connects single-chip microcomputer, described single-chip microcomputer connects respectively the charactron of display screen, loudspeaker, function button and locking key; Also comprise gravitational accelerometer, the signal transmission end of described gravitational accelerometer is connected with single-chip microcomputer, and described gravitational accelerometer feeder ear is connected with power supply.
The beneficial effects of the utility model are as follows:
The utility model structure is simple, can independently use, and also can be positioned over and play occasionally in suspension member, be easy to carry, operational platform design is reasonable, and display screen can show state, setting value, parameter etc., and function button can be used for setting displacement range numerical value, removing and eliminate, locking key can start warning by a key, easy to operate, the utility model step number shift value is set by function key, start locking key, inner gravitational accelerometer will be in induction detected state, when the utility model is vibrated or significantly displacement exceedes setting value, gravitational accelerometer will send detection signal, signal is sent in single-chip microcomputer, single-chip microcomputer is responded this signal and to be given the alarm sound by loudspeaker, utilize this principle the utility model can be able to be hung on easily to steal on article in mobile phone and handbag etc., play alarm anti-theft function, also the utility model can be placed on baby, old man or needs are escorted with it the convict that keeps an eye on, play nurse alarm function.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model.
Fig. 2 is the block diagram of system of the present utility model.
Wherein: 1, loudspeaker; 2, display screen; 3, function button; 4, locking key; 5, gravitational accelerometer; 6, power supply; 7, single-chip microcomputer; 8, housing.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.
As shown in Figure 1 and Figure 2, the meter step induction alarm device of the present embodiment, comprise housing 8, display screen 2 is provided with in the middle part of housing 8, display screen 2 top is loudspeaker 1, the bottom of display screen 2 is provided with multiple function button 3, the bottom of function button 3 is locking key 4, display screen 2 can show state, setting value, parameter etc., function button 3 can be used for setting step number displacement range numerical value, arranges password, eliminate alarm etc., can need according to difference the interval time setting vibrating numerical and the clearing of accumulative step number, locking key 4 can start warning by a key, easy to operate, power supply 6 is installed in housing 8 inside, and power supply 6 output terminal connects single-chip microcomputer 7, single-chip microcomputer 7 connects respectively the charactron of display screen 2, loudspeaker 1, function button 3 and locking key 4, also comprise gravitational accelerometer 5, the signal transmission end of gravitational accelerometer 5 is connected with single-chip microcomputer 7, gravitational accelerometer 5 feeder ear is connected with power supply 6, (in figure, just generally show roughly annexation and the relative position of power supply 6 and other assemblies, may be different in actual product), the utility model step number shift value is set and after starting locking key 4 by function button 3, gravitational accelerometer 5 will be in induction detected state, when the utility model is vibrated or significantly displacement exceedes setting value, gravitational accelerometer 5 will send detection signal, signal is sent in single-chip microcomputer 7, single-chip microcomputer 7 is responded this signal and to be given the alarm sound by loudspeaker 1.
The utility model shell 8 can be designed to the suspension member of various style or ornaments independently use, and also the utility model directly can be positioned in doll or suspension member, good looking appearance is changeable, easy to carry, plays the effect of burglar alarm at any time; Also can be positioned over need nurse baby or old man with it, can give the alarm when displacement step number exceeds nurse scope remind ward pay close attention to; Law enforcement agency can also be applied to escort and take suspect into custody, bind the utility model with it suspect, when suspect flee from step number exceed setting numerical value time, will alarm song be caused, remind keep an eye on law enfrocement official.Corresponding cell phone software can be derived thus be applied in and have on gravity sensing function mobile phone, use meter step inductor combining cipher lock control, realize anti-theft security function.
The concrete use procedure of the utility model is as follows:
First, the step number displacement critical value of alert trigger is set by function button 3; Then, press and start locking key 4, now gravitational accelerometer 5 enters detected state, when the utility model is greater than the displacement of critical value, gravitational accelerometer 5 transmission signal causes loudspeaker 1 to sound the alarm, thus reminds victim and people around, frightens the person of hatching a sinister plot to a certain extent; Chimes of doom will continue, until input correct unlock password by function button 3.
More than describing is to explanation of the present utility model, and be not the restriction to utility model, the utility model limited range, see claim, within protection domain of the present utility model, can do any type of amendment.
