Summary of the invention:
The objective of the invention is to overcome above-mentioned not enough problem, a kind of open type super high frequency RF recognition protocol platform is provided, support various protocols, label, be easy to new standard compatibility, upgrading, speed height.
The technical scheme that the present invention is adopted for achieving the above object is: open type super high frequency RF recognition protocol platform, by radio frequency unit, radio frequency control unit (claiming baseband processing unit again) and intelligent processing unit constitute, radio frequency unit and electronic tag carry out wireless telecommunications, to the signal amplification, the modulation that receive and send to the radio frequency control unit, the radio frequency control unit is realized the high-speed parallel processing to signal encoding, decoding; Intelligent processing unit is that microprocessor connects memory and communication interface, the agreement function library is stored in the memory, microprocessor driven, carry out by the encoding and decoding protocol processor, to the anti-collision of many tag access, many read write lines anti-collision, internal memory RFID upper-layer protocol standard and open development platform thereof, customizable read write line control command collection with powerful secondary development function.
Described agreement function library mainly comprises IS018000-6A/B protocol stack, EPC Class0 protocol stack, EPC Class1 protocol stack and EPC Class1 Gen2 protocol stack.
Described agreement function library can customize professional communications protocol according to user's needs, is used for special industry (such as army), improves safeguard protection.
Described agreement function library is open, to new agreement, operating such support.
The peripheral interface of described UHF read write line can be RS232, RS-485, I2C SPI, Ethernet interface etc., and the communication of it and PC/peripheral controllers is supported perfect order line configuration and management by the special purpose interface agreement.The communications protocol of itself and PC/peripheral controllers, by country or manufacturer is unified provides, or according to customization.
Advantage of the present invention is: system rationally, simply, non-physically simply integrated, not only can support multi-protocols, and rate of reading fast, the efficient height can reduce cost greatly, and open platform, be easy to compatibility, the upgrading of new standard, accelerate the construction cycle of new product, use more extensive.
