Abstract

The invention relates to a rapid response and long-distance identification radio-frequency tag which comprises a radio-frequency chip, a main control MCU, etc.; the invention is provided with a global unique ID number, variable information which has 4K byte maximal capacity and can be rewritten by users; a special factory power-saving mode, thereby reducing meaningless energy consumption. At the same time, the invention provides a communication mechanism with rapid response between a reader-writer and a tag, which comprises the following: the first step: the reader-writer emits an enabled broadcast frame; the second step: the tag receives the enabled broadcast frame; the third step: the tag carries out random delay; the fourth step: the tag carries out signal channel detection; the fifth step: the tag sends data information; the sixth step: the reader-writer receives the data information of the tag; the seventh step: the tag verifies whether the reader-writer receives the data information or not; the eighth step: the tag enters into a long dormant state. The invention can meets the requirements of remote identification and rapid response in practical application and can solve the practical application in management of outdoor billboards, container freight stations, etc.

Description

technical field [0001] The invention relates to a long-distance radio frequency identification, in particular to a fast-response long-distance identification radio frequency tag. Background technique [0002] RFID technology is the abbreviation of Radio Frequency Identification, which means radio frequency identification, which is a new technology in the field of automatic identification. It automatically identifies the target object and obtains relevant data through radio frequency communication signals. The identification work does not require manual intervention and can work in various harsh environments. Radio frequency identification technology has the ability to identify high-speed moving objects and can identify multiple tags at the same time. In short, radio frequency identification technology has the characteristics of being able to identify multiple objects at the same time, readable and writable, strong penetrating power, long recognition distance, fast recogniti...
