Brief description of the drawings
Self-powered RFID label construction schematic diagram in Tu1Shi the utility model transformer station.
In figure, transmission circuit and the storer 4 of MK antenna 1, the conversion of MK power supply and Circuit tuning 2, RFID label antenna 3, RFID label.
Embodiment
Below in conjunction with accompanying drawing and concrete enforcement, the utility model is further described.
As shown in Figure 1, the self-powered RFID label in transformer station is by MK antenna 1 for self-powered RFID label construction in the utility model transformer station, and MK power supply is changed and Circuit tuning 2, RFID label antenna 3,4 four modules compositions of the transmission circuit of RFID label and storer.MK antenna 1 is connected with one end of the conversion of MK power supply and Circuit tuning 2, one end of the conversion of MK power supply and the other end of Circuit tuning 2 and the transmission circuit of RFID label and storer 4 is connected, and the other end of the transmission circuit of RFID label and storer 4 is connected with RFID label antenna 3.
Described MK antenna 1 becomes to be suitable for the transmission circuit of RFID label and the power supply of memory circuitry module work by transformer station compared with low-frequency range strong-electromagnetic field energy conversion after being connected with the conversion of MK power supply and Circuit tuning 2.
After being connected, the transmission circuit of described RFID label antenna 3 and RFID label and memory circuitry 4 realize and the communicating by letter of read write line according to corresponding agreement.
Self-powered RFID label in transformer station has anti-metallicity.
When the utility model is specifically implemented:
MK antenna 1 is the MK antenna that is applicable to receiving lower frequency strong-electromagnetic field energy in substation, the conversion of MK power supply and Circuit tuning 2, the electrical signal energy that MK antenna 1 is received is converted to power supply, and adjust, comprise and boosting or the processing procedure such as voltage stabilizing, current limliting, pressure limiting, make voltage interval in being suitable for, be used as the suitable working power of RFID label for label; RFID label antenna 3 adapts to the frequency of operation of card reader and label receive-transmit system, and matches with the transmission circuit input impedance of RFID label, the command signal that antenna reception card reader is sent, and beam back the information of returning to its response to card reader; The transmission circuit of RFID label and memory module 4, include analog radio frequency front-end circuit and digital signal processing circuit, storer (chip internal or outside), clock generating and sequential logical circuit, can also there be the sensors such as temperature/pressure and corresponding A/D, D/A circuit etc.They are under corresponding agreement constraint, and works according to the rules, processes to the received signal; And according to the card reader instruction obtaining, the information that storer or label are collected, sends by RFID label antenna 3.
The workflow of the transmission circuit of RFID label and memory module 4: it works under the power supply that MK power supply is changed and Circuit tuning 2 provides, to processing from the signal of RFID label antenna 3.The radiofrequency signal obtaining is amplified or directly cooking, to MCW modulated carrier wave demodulation, obtain or generation system need clock, carry out demodulation, decoding or other operation of signal according to protocol requirement, read or image data according to sequential process, command request, also can be to storer data writing; Then, the data encoding that needs are responded, the transfer rate specifying according to agreement and sequential modulation, from the carrier wave of card reader, send to card reader from RFID label antenna 3.
