Embodiment Construction

[0071] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0072] The solution to the multi-tag conflict in the radio frequency identification system of the present invention comprises the following steps, wherein, figure 1 Represented the realization step of step 40 to step 80 in the method of the present invention:

[0073] Step 10. Power on the tag to make it in the initialization state.

[0074] Step 20, the reader issues an "initialization command", and after the tag receives the command, the counter (count) is cleared, and then enters the active state. The significance of counter clearing is to ensure that each tag is in an active state at the beginning, so as to be able to respond to the query command of the reader. When the tag is in the active state, it can send information to the reader, and in other states, it cannot perform the operation of sending information.

Abstract

This invention discloses one radio frequency identification system multi-label collision method, which comprises the following steps: a, reader sending initial order and activating label; b, reader orderly requires and records label each bit from high to low bit and judges if each bit is same, if not then it is a collision marked by certain character; otherwise records original value; c, reader substitutes each collision bit by 0 and 1 from high bit and identifies the bits and sends relative orders; d, label receives orders and are converted between each status according to current status and order information to solve the collision.

Description

technical field [0001] The invention relates to video recognition technology, in particular to a solution to multi-label conflicts in a radio frequency identification system. Background technique [0002] Radio Frequency Identification (RFID) is a low-power, short-range communication technology. As one of the most potential identification technologies, radio frequency identification technology has become a research hotspot in the field of IT. [0003] The identification principle of radio frequency identification is to use inductive coupling (Inductive Coupling) or backscatter (Backscatter) to realize the information transmission between the tag and the reader. The communication frequency between the reader and the tag is mainly concentrated in the low frequency (below 135KHz), high frequency (13.553 ~ 13.567MHz), ultra high frequency (400 ~ 1000MHz), microwave (2.45GHz) and other frequency bands. A simple RFID system usually consists of tags, readers, and application soft...
