Semi-active magnetomechanical tags realize the realization method of semi-active function：Magnetomechanical tags internally embody active label feature,Battery is installed, control unit can be to the wired read-write of RF radio frequency units inside magnetomechanical tags；Magnetomechanical tags externally embody passive labelFeature, RF radio frequency units are communicated using passive passive mode with extraneous card reader, and power consumption is substantially reduced.
Semi-active magnetomechanical tags realize the realization method of card business function：Before magnetomechanical tags normal work, magnetomechanical tags are putOn card sender, by system management software registered tags, magnetomechanical tags can be normally by the system management software after succeeding in registrationMonitoring；When magnetomechanical tags power cut-off, magnetomechanical tags are placed on card sender, label, magnetic force are nullified by the system management softwareAfter label is nullified successfully, the entire record flow of magnetomechanical tags can all be stored by the system management software；Magnetomechanical tags usually non-workBefore making in a dormant state, magnetomechanical tags power consumption is very low, and when succeeding in registration, magnetomechanical tags are waken up, and works as and nullify successfully then magneticPower label is again by suspend mode.
Semi-active magnetomechanical tags realize that card business function can be used same RF radio frequency unit itself and realize, or using other frequenciesPoint mode is realized.
Semi-active magnetomechanical tags realize the realization method of dismantling-proof alarming function：Sensor unit is mounted on magnetomechanical tags bottomPortion, when magnetomechanical tags are adsorbed on object iron plate surface, if there is the dismounting of artificial malice, magnetomechanical tags have alarm.HalfFor active magnetomechanical tags when realizing dismantling-proof alarming function, there are two types of the specific implementations of alarm：Pass through pressure sensingDevice is realized, or is realized by magnetometric sensor.Report of the semi-active magnetomechanical tags in dismantling-proof alarming is realized by pressure sensorAlert prompt process specifically includes：Sensor unit uses pressure sensor, when magnetomechanical tags are adsorbed on body surface, body surfaceDynamic pressure act on pressure sensor component, so that element is deformed, pressure sensor export a fixed simulationMagnitude；When someone's malice removes mobile magnetomechanical tags, the dynamic pressure of body surface changes, pressure sensor outputAnalog value changes therewith；When pressure data is more than threshold value, control unit receives analog quantity and is deposited in memory modulePressure data is stored up, and to RF radio frequency units by wired communication protocol, operation is written and read to RF radio frequency unit data portions, it willPressure sensor alert data writes RF radio frequency unit data modules；When external card reader reads magnetomechanical tags, card reader can be withThe data bit that pressure alarm is indicated in RF radio frequency unit data modules is read, simultaneity factor software also receives RF radio frequency unit numbersAccording to and with compared with storing data when hair fastener, pressure alarm data variation is such as indicated, then differentiate that system software can there are dismantling-proof alarmingDo alarm.Realize that alarm process of the semi-active magnetomechanical tags in dismantling-proof alarming is specifically wrapped by magnetometric sensorIt includes：Sensor unit uses magnetometric sensor, magnetometric sensor to be adsorbed on object using Hall component, magnetic resistance, magnetomechanical tagsWhen surface, since body surface is iron sheet, magnetomechanical tags internal magnetic field field strength is certain, and magnetometric sensor is exported according to magnetic field intensityOne stable analog quantity；When someone's malice removes mobile magnetomechanical tags, therefore magnetomechanical tags field strength changes, mouldAnalog quantity changes therewith；When analog quantity is more than threshold value, control unit receives analog quantity and in memory module storage tapeIntensity data, and to RF radio frequency units by wired communication protocol, operation is written and read to RF radio frequency unit data modules, by magneticForce snesor alert data writes RF radio frequency unit data modules；When external card reader reads magnetomechanical tags, card reader can be readTo the data bit for indicating magnetometric sensor alarm in RF radio frequency unit data modules, simultaneity factor software also receives RF radio frequency listsMetadata simultaneously compared with storage data, such as indicates the variation of magnetometric sensor alert data when hair fastener, then differentiates there are dismantling-proof alarming,System software can do alarm.
The present embodiment is a kind of newly developed semi-active magnetomechanical tags.There are battery, but battery in the semi-active magnetomechanical tagsIt only powers to the inside tags circuit, which can be communicated by wired mode with various sensors, is realized and is believed with external environmentBreath interaction.The label does not emit signal actively, and communication is similar with passive label, and signal wireless transmission energy is logicalIt crosses extraneous card reader to provide, therefore is compared than active label, it is low in energy consumption, at low cost, it is often more important that safeguard also very convenient.The markLabel are internal to be equipped with semi-active label, and magnetomechanical tags are adsorbed on object iron plate surface, is internally read by the active active of battery eachKind sensor parameters, obtain external environment parameters（Such as temperature, humidity, magnetic field intensity）, then passive to be passively sent to readingCard device not only realizes the monitoring position of object and traces to the source, even more the data by building external environment and platform system softwareInteraction, realizes and traces to the source the condition monitoring and history of object surrounding enviroment.The semi-active magnetomechanical tags of the present embodiment can be extensiveApplied to fields such as transport, safety guards, such as in vaccine cold chain system, since vaccine is temperature sensitive, manufactured from vaccineThe scene that is used to vaccine of department between each link, may all fail because temperature is excessively high, described in the present embodimentSemi-active magnetomechanical tags apply in the preservation in vaccine, transport and the links that use, can be with strict guarantee planned immunizationThe vaccine applied from production, storage, transport, be distributed to the whole process used and have appropriate refrigerating equipment, make vaccine alwaysUnder cold insulation state as defined in being placed in, ensure that the reasonable potency of vaccine is without damage.
