Background technique
Microwave radio identification (UHF RFID) technology is state-of-the-art forth generation automatic identification technology in the world, is in recent years
Just start the new technology risen and promoted and applied rapidly, it has, and identification distance is remote, recognition accuracy is high, identification speed
The features such as degree is fast, strong antijamming capability, long service life, can penetrate the features such as nonmetallic materials, and operation strategies are wide.It is for reality
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.
Summary of the invention
No longer only target object is remembered it is an object of the invention to overcome the deficiencies of the prior art and provide a kind of
Record, calibration, can also be monitored target object local environment, expand the UHF_ of the scope of application of RFID information system
RFID passive label.
The purpose of the present invention is achieved through the following technical solutions: a kind of novel UHF_RFID passive label, packet
Include power module, antenna element, air protocol module, memory module and sensor, power module respectively with antenna element, eat dishes without rice or wine
Protocol module, memory module are connected with sensor, and air protocol module is connected with antenna element and memory module respectively, sensor
It 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 present invention are: passive label of the invention has widened the application scenarios of UHF RFID, label is no longer
Only target object is recorded, is demarcated, target object local environment can also be monitored, computer system can be with
Obtain the environmental data of real-time update.By this environmental data, computer system can analyze object in this stage
The state of experience, environmental change, and most reasonable processing is made to object.Expand the scope of application of RFID information system.
Detailed description of the invention
Fig. 1 is typical RFID information system model；
Fig. 2 is UHF_RFID passive label structural schematic diagram of the invention；
Fig. 3 is the workflow of UHF_RFID passive label of the invention；
Fig. 4 is the RFID information system of UHF_RFID passive label according to the present invention design.
Specific embodiment
Technical solution of the present invention is further illustrated with reference to the accompanying drawing.
The present invention devises a novel passive label, and the storage section of the label is no longer single channel, unidirectional
Data transmission.The memory module of the label can modify the content in memory module by the transferring content with sensor, realize
Data in memory module can change according to environmental change.Computer system can interact in memory module according to label
Data, 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,
Air protocol module is connected with antenna element and memory module respectively, and sensor is connected with memory module.
Further, further, the antenna element is used to obtain the electromagnetic signal in region, and electromagnetic signal is mentioned
It supplies air protocol module and carries out data interaction；The antenna element is used to convert electric energy for electromagnetic signal, and passes to electricity
