Description
Technical field
The invention belongs to active label technical field, relate in particular to a kind of Anti-dismantling 2.45GHz active label with electronic lock.
Background technology
Have or not according to label in-line power, RFID label is divided into passive type, semi-passive (also referred to as semi-active type), active three classes.Different from passive type and semi-passive, active tag itself has internal electric source supply, in order to supply the required power supply of inner IC to produce external signal.In general, active tag has long reading distance and can hold larger memory size and can be used for storing some appended messages that reader sends.Active and semi-passive label difference is; Active tag can be by internal power, initiatively launches at any time the internal document of inner label to reader.Active tag is called again active label, and built-in battery can utilize own electric power label around, to form effective behaviour area, the call signal that initiatively has or not reader to launch 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 made up of label, plug-in reader and data transmission and disposal system three parts.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.The features such as RFID label has persistence, and it is strong that information receives propagation penetrability, and storage information capacity is large, kind is many.Some RFID label is supported read-write capability, and the information of target object can be updated at any time.Active electronic label refers to that the energy of label work is provided by battery, and battery, internal memory form active electronic label together with antenna, are different from the active mode of passive radio frequency, last straight through setting photos and sending messages outside frequency range 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 utilizes a kind of resistance value that semi-conductive photoconductive effect is made to change with the power of incident light, is called again photoconductive detector; Incident intensity, resistance reduces, and a little less than incident light, resistance increases.A little less than also having another kind of incident light, resistance reduces, incident intensity, and resistance increases.Photoresistance belongs to optical semiconductor sensing device, and highly sensitive except tool, reaction velocity is fast, outside the features such as spectral characteristic and r value high conformity, at high temperature, under how wet rugged surroundings, can also keep stability and the reliability of height, can be widely used in camera, 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 adopt it.According to the spectral characteristic of photoresistance, can be divided into three kinds of photo-resistors: 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 must do tamper processing to label, prevent that lawless person from stealing label, disassemble rear acquisition chip significant data, if tag application militarily, label tamper is a worth problem that conscientiously research is treated especially.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, in the situation that not destroying label shell structure, mechanical switch can not play a role; Adopt the electronic tag of magnetic switch, in the time of dismounting label, label is placed in a high-intensity magnetic field, protection was lost efficacy immediately.
