Now digitlization, one kind information-based and that the characteristics such as the attribute to object, state, number progress automatic collection is released are completely new
Management means can be widely applied to the identity automatic identification of personnel, animal, article etc..
Currently, the working model of UHF RFID is that encoded label is attached on object, passes through dedicated RFID
Reader obtains the encoded information and storing data content of label, to realize to the automatic identification of object and trace ability.
Label does not need battery, obtains energy from the electromagnetic field that reader issues when being identified.
Fig. 1 is exactly a typical RFID information system model, initiates to operate by computer system, and control reader is sent
Identification instruction sends radio magnetic wave by antenna, the energy in electromagnetic field is obtained in the label in electromagnetic wave region, with read-write
Device carries out data interaction, label coding and memory block content is reported to computer system, computer system is according to label information
Assertive goal object, record, spotting object information.
Due to the information storage of passive label be it is unidirectional, i.e., can only be operated by reader, to passive label
Memory block is written and read, so the information in label is that have initial read-write equipment write-in, and by it in transmission process
His read-write equipment is read, or modification.It can not be recorded object by the variation according to real time environment and transmitted institute on the way
The some situations of change encountered, can limit to the use scope of radio-frequency recognition system.RFID information system usage scenario will be more single
One, it is unfavorable for enriching, promoting the use of RFID information system.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide it is a kind of be no longer only to target object into
Row record, calibration, can also be monitored target object local environment, expand the scope of application of RFID information system
UHF_RFID passive label.
The purpose of this utility model is achieved through the following technical solutions: a kind of novel passive mark of UHF_RFID
Label, including power module, antenna element, air protocol module, memory module and sensor, power module respectively with antenna list
Member, air protocol module, memory module are connected with sensor, air protocol module respectively with antenna element and memory module phase
Even, sensor is connected with memory module.
Further, the antenna element is used to obtain the electromagnetic signal in region, and electromagnetic signal is supplied to and is eated dishes without rice or wine
Protocol module carries out data interaction；The antenna element is used to convert electric energy for electromagnetic signal, and passes to power module, energy
Electric energy enough is provided to passive label using electromagnetic signal, label is made to enter working condition；
Air protocol module is used to provide the data information of reader needs, and carries out data interaction with reader；
Memory module is for storing label coding and user information；Meanwhile memory module also opens up a piece of memory space, uses
Carry out the environmental variance information that storage sensor sends over, and environmental variance information is uploaded to reader；
Sensor is used to obtain environmental variance information in real time, and the variable information is recorded to the corresponding sky of memory module
Between；Sensor is used to convert electric energy for the mechanical energy of environmental change, and passes to power module, to support memory module to biography
The write-in of sensor input data.
The beneficial effects of the utility model are: the passive label of the utility model has widened the application scenarios of UHF RFID,
Label is no longer only to be recorded, demarcated to target object, can also be monitored to target object local environment, computer
System can obtain the environmental data of real-time update.By this environmental data, computer system can analyze object and exist
The state of this stage experience, environmental change, and most reasonable processing is made to object.Expand being applicable in for RFID information system
Range.
Detailed description of the invention
Fig. 1 is typical RFID information system model；
Fig. 2 is the UHF_RFID passive label structural schematic diagram of the utility model；
Fig. 3 is the workflow of the UHF_RFID passive label of the utility model；
Fig. 4 is the RFID information system designed according to the UHF_RFID passive label of the utility model.
Specific embodiment
The technical solution of the utility model is further illustrated with reference to the accompanying drawing.
The utility model devises a novel passive label, and the storage section of the label is no longer single channel, folk prescription
To data transmission.The memory module of the label can modify the content in memory module by the transferring content with sensor,
Realize that the data in memory module can change according to environmental change.Computer system can store mould according to interacting with label
Data in block, to obtain environmental change situation locating for object.
As shown in Fig. 2, a kind of novel UHF_RFID passive label, including power module, antenna element, air protocol mould
Block, memory module and sensor, power module are connected with antenna element, air protocol module, memory module and sensor respectively,
