Problems solved by technology

At present, there are international standards such as ISO18000-6, EPC Class0, and Class1. my country has not formulated its own national standards. Therefore, various standard protocols for UHF are constantly changing and upgrading. It only supports a single protocol. Even if it supports multiple protocols, it is a simple physical integration. Developing related equipment and protocol stacks for a certain standard protocol has obvious limitations and high costs.

Embodiment 1

[0018] Embodiment 1: The present invention is applied to coal safety management system

[0019] Such as Figure 4 , 5 Shown: The coal safety management system consists of EPC Class0, EPC Class1 and EPC Class1 Gen2 radio frequency electronic tags 1, UHF RFID protocol platform system (1) 2, UHF RFID protocol platform system (2) 2, UHF RFID The protocol platform system (N) 2 is composed of upper computer management system 3, and each channel of the UHF protocol platform is set up, such as figure 1 , 2 As shown, it is composed of a radio frequency unit, a radio frequency control unit (also known as a baseband processing unit) and an intelligent processing unit. The intelligent processing unit is a microprocessor connected to a memory and a communication interface. The protocol function library is stored in the memory. The protocol function library mainly includes EPC Class0 protocol stack, EPC Class1 protocol stack and EPC Class1Gen2 protocol stack. Microprocessor-driven, exec...

Embodiment 2

[0021] Embodiment 2: the present invention is applied to the highway toll system

[0022] Such as Figure 6 The expressway toll system shown mainly uses the open UHF RFID protocol platform system to realize the automatic identification function of vehicles at a long distance, and merges the automatically collected vehicle information into the expressway toll system.

[0023] UHF RFID with ISO18000-6A / B, EPC Class0, EPC Class1 and EPC Class1 Gen2 radio frequency tags1, supporting ISO18000-6A / B protocol stack, EPC Class0 protocol stack, EPC Class1 protocol stack and EPC Class1 Gen2 protocol stack Protocol platform system 2, expressway toll system (intersection 1) 3, expressway toll system (intersection 2) 3, expressway toll system (intersection N) 3, wherein, the radio frequency electronic tag is installed on the vehicle, when he passes the overpass When the electromagnetic field range (toll intersection) covered by the high frequency RFID protocol platform system, the UHF RFID...

Abstract

This invention relates to an open super-high frequency RF identification protocol platform composed of a RF unit, a RF control unit and an intelligent process unit, among which, the RF unit carries out radio communication with electronic labels to amply, modulate and demodulate received signals and send them to the RF control unit, which codes and decodes the signals to realize high speed parallel process, the intelligent process unit connects a storage and a communication interface for the microprocessor, protocol function is stored in the storage, the code-decode protocol processor drives the microprocessor, a reader control instruction set with strong secondary development function can be designed against the striking to multiple label access, anti-conflict of multi-reader and for the memory RFID high level protocol standard and its open development platform.

Description

Technical field: [0001] The invention relates to a radio frequency identification protocol platform and belongs to the technical field of radio frequency identification. Background technique: [0002] Radio frequency identification (RFID) technology is developing rapidly abroad. There are many types of RFID products. Some internationally renowned manufacturers produce RFID products, and their products have their own characteristics and form their own series. Especially with the introduction of the EPC concept and the emergence of low-cost radio frequency tags, it is no longer a distant future for radio frequency tags to enter the daily life of thousands of households. At present, radio frequency identification technology is widely used in many fields such as industrial automation, commercial automation, and transportation control management: traffic monitoring of automobiles and trains; automatic toll collection system for highways; parking lot management system; item manage...
