Nested matrix-based electronic tag reading system and a reading method thereof

Abstract

The invention relates to an electronic tag reading system based on a nested matrix, which is characterized in that a main controller is connected with a plurality of sub-controllers, the main controller is used for commanding each sub-controller to simultaneously acquire, upload and display data of an electronic tag, and each sub-controller is respectively connected with a respective correspondinginterface board unit through a data bus; Each interface board unit is provided with a plurality of interface boards arranged in a matrix mode, and each interface board is connected with a plurality of electronic tags arranged in a matrix mode. The sub-control MCU of each sub-controller is provided with a plurality of transverse and longitudinal GPIO buses; Each transverse GPIO bus is connected with the grounding pins of the electronic tags in the same row on the corresponding interface board in the same row, and each longitudinal GPIO bus is connected with the IO pins of the electronic tags in the same column on the corresponding interface board in the same column to form a matrix bus control structure. Bus resources can be greatly saved, power consumption and cost are effectively reduced, physical delay is reduced, and the data reading efficiency and accuracy of the electronic tag and the system stability are improved.

Description

technical field [0001] The invention relates to a system for reading electronic tags based on a nested matrix type and a reading method thereof, belonging to the technical field of optical communication. Background technique [0002] With the mass construction of the national optical fiber basic network, this makes the ODN network user end generate a large number of optical fiber lines that need to be dispatched, maintained and managed. Traditional optical fiber management uses manual identification of paper documents and paper labels for construction and maintenance, which makes management costs very high and efficiency low. Omissions in manual management will cause inconsistencies between network data and actual network conditions, and the difficulty of subsequent network maintenance will increase significantly. [0003] The optical wiring management technology of intelligent ODN is based on electronic labels, and each optical fiber active connector is equipped with an el...

AI Technical Summary

Problems solved by technology

The increase of expansion chips and driver chips will increase the cost and power consumption of hardware circuits.

The logical control of this structure is relatively complicated. Due to the two-level physical delay, it not only affects the correctness of the data read by the electronic tag, but also the system stability is not high.

When the CPU reads data from thousands of electronic tags, the traversal cycle is longer, which will affect the real-time detection of electronic tags and the accuracy of read data
