Description
Technical field
The utility model belongs to active label technical field, particularly relates to a kind of Anti-dismantling 2.45GHz active label.
Background technology
According to inside tags power with or without, RFID label tag is divided into passive type, semi-passive (also referred to as semi-active type), active three classes.With passive type and semi-passive unlike, active tag itself has internal electric source supply, in order to supply power supply needed for inner IC to produce external signal.In general, active tag has longer reading Distance geometry and can hold larger memory size and can be used for storing some appended messages of sending of reader.Actively with semi-passive label difference be; Active tag by internal power, can initiatively launch the internal document of inner label on reader at any time.Active tag is also called active label, built-in battery, can utilize own electric power around label, form effective behaviour area, the call signal of initiatively launching with or without reader arround detecting, and by the data transmission of self to reader.Electronic tag is the popular call of radio-frequency (RF) identification (RFID), and it is transmitted by label, plug-in reader and data and disposal system three part forms.Be also referred to as electronic tag or intelligent label, it is the chip of internal memory with antenna, stores the information that can identify target in chip.RFID label tag has persistence, and it is strong that receives information propagates penetrability, stores the features such as information capacity is large, kind is many.Some RFID label tag supports read-write capability, and the information of target object can be updated at any time.Active electronic label refers to that the energy of labeling task is provided by battery, and battery, internal memory form active electronic label together with antenna, is different from the active mode of passive radio frequency, last straight through setting frequency range outgoing messages at battery altering.The source electronic tag of common are works in 433MHz frequency range or 2.4GHz working frequency range.Photo-resistor is the resistor that a kind of resistance value utilizing the photoconductive effect of semiconductor to make changes with the power of incident light, is also called photoconductive detector; Incident intensity, resistance reduces, and incident light is weak, and resistance increases.Also have another kind of incident light weak, resistance reduces, incident intensity, and resistance increases.Photoresistance belongs to optical semiconductor sensing device, and except tool is highly sensitive, reaction velocity is fast, outside spectral characteristic and the feature such as r value consistance is good, at high temperature, under many wet rugged surroundings, stability and the reliability of height can also be kept, camera can be widely used in, solar energy garden lamp, Lawn lamp, cash inspecting machine, crystal clock, music cup, gift box, mini mini light night, light audio-switch, street lamp automatic switch and various light-operated toy, light-operated lamp decoration, the light automatic switch control fields such as light fixture.Photoresistance divides by semiconductor material: Intrinsical photoresistance, doping type photoresistance.The latter's stable performance, characteristic is better, therefore mostly adopts it.According to the spectral characteristic of photoresistance, three kinds of photo-resistors can be divided into: 1, ultraviolet photoresistor; 2, infrared photoresistor; 3, visible light photoresitor.2.45GHz electronic tag is in current Internet of Things field extensive application, because portability is high, so tamper process must be done to label, prevent lawless person from stealing label, disassemble rear acquisition chip significant data, if label application militarily, label removal prevention especially one be worth conscientiously study the problem treated.Existing 2.45GHz electronic tag tamper technology mostly adopts the mode such as mechanical switch, magnetic switch.Both have larger defect, adopt the label of mechanical switch tamper, if dismounting personnel adopt professional equipment, when not destroying label shell structure, mechanical switch can not play a role; Adopting the electronic tag of magnetic switch, when dismantling label, being placed on by label in a high-intensity magnetic field, protection was lost efficacy immediately.

Wherein, 1, label housing; 2, photoresistance; 3, label chip; 4, label mainboard; 5, mechanical switch.
Embodiment
Below in conjunction with accompanying drawing, Anti-dismantling 2.45GHz active label of the present utility model is described further.
As shown in Figure 1, for a kind of Anti-dismantling 2.45GHz active label of the present utility model, comprise label housing 1, label chip 3, label mainboard 4 and mechanical switch 5, described mechanical switch 5 is positioned at label housing 1 inner bottom part, described label mainboard 4 is placed on mechanical switch 5, and described label chip 3 is placed on label mainboard 4; Also comprise photoresistance 2, described photoresistance 2 is placed on label mainboard 4.Photoresistance 2 is adjacent to label chip 3.Emergency processing program is provided with in label chip 3.Photoresistance can adopt 5528 models.Label mainboard can adopt pcb board.Label chip can adopt EPC G2 chip.Label housing can adopt PVC material.
Be described further below in conjunction with the principle of work of the drawings and specific embodiments to Anti-dismantling 2.45GHz active label of the present utility model.
When dismantling personnel's unauthorised broken label housing 1, the shell structure of label housing 1 can be destroyed, and the pressure suffered by mechanical switch 5 can change.Now, mechanical switch 5 will play a role, and prevent active label by unauthorized theft.If but dismounting personnel adopt artificial certain measures, under the prerequisite not destroying shell structure, can carry out unauthorized theft to active label, now mechanical switch 5 can not play a role.When dismounting personnel illegally open label housing 1, the light intensity value in transition housing 1 can change, that the photoresistance 2 now in label housing 1 can sense light intensity value and the resistance value of self is changed.Here photoresistance 2 adopts highly sensitive, that reaction velocity is fast visible light photoresitor.Label chip 3 can detect by detection module the change from variable caused by the resistance change of photoresistance 2, and compares with the value of appraising and deciding when not being disassembled.
As shown in Figure 1, when active label works, label chip 3 can detect the state of mechanical switch 5 and photoresistance 2, if exceed setting threshold value, then can be judged as artificial illegal dismounting.Now, label chip 3 can start emergency processing program, protects the significant data in active label, prevents data by unauthorized theft.
Those of ordinary skill in the art will appreciate that, embodiment described here is to help reader understanding's principle of the present utility model, should be understood to that protection domain of the present utility model is not limited to so special statement and embodiment.Those of ordinary skill in the art can make various other various concrete distortion and combination of not departing from the utility model essence according to these technology enlightenment disclosed in the utility model, and these distortion and combination are still in protection domain of the present utility model.
