Embodiment Construction

[0030] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0031] refer to figure 1 , figure 1 It is a schematic flow chart of the first embodiment of the control method of the tag recognition distance of the present invention; figure 1 As shown, the control method of the tag recognition distance of the present invention specifically includes the following steps:

[0032] Step S01, configuring the power adjustment accuracy of different protocol labels;

[0033] The method of controlling the tag identification distance is usually to adjust the tag’s transmit power value. When adjusting the tag’s transmit power value, a certain power adjustment accuracy needs to be configured; if the power adjustment accuracy is too large, i...

Abstract

The invention discloses a method for controlling a label identification distance. The method comprises the following steps: configuring power regulation accuracy of different protocol labels; according to a target distance and the power regulation accuracy, controlling transmitting power of the labels so as to enable the coverage range of the labels to be consistent. The invention also discloses a reader and a system for controlling the label identification distance, which comprises the reader. The method, which enables the coverage range of the labels to be consistent by configuring the power regulation accuracy of different protocol labels and controlling the transmitting power of the labels according to the target distance and the power regulation accuracy, disclosed by the invention has the beneficial effects that radio frequency labels of different protocols can be accurately identified in the same coverage range; unnecessary label misreading is avoided when improving the identification efficiency.

Description

technical field [0001] The invention relates to the technical field of radio frequency identification, in particular to a method for controlling the identification distance of tags. Background technique [0002] The radio frequency identification system mainly includes radio frequency identification tags (referred to as tags) and readers. It is a non-contact automatic identification technology that automatically identifies target objects and obtains relevant data through radio frequency signals. This kind of harsh environment, such as warehousing, logistics, transportation and many other fields, is one of the most important application technologies in the future Internet of Things. [0003] At present, there are two protocols widely used in UHF RFID tags: ISO18000-6B and EPC C1G2 (Electronic Product Code, product electronic code; this protocol is also called ISO18000-6C). In actual application scenarios, it may involve The problem that multiple protocol tags exist in the sa...
