Knife handle identification method

Abstract

The invention discloses a knife handle identification method at a short distance and a long distance simultaneously. The identification method does not influence a dynamic balance characteristic of a knife handle, identification speed is fast, identified content can be rapidly changed, information of knife-cutter is stored in the knife handle, and the information flows with circulation of the knife handle. The method does not influence the dynamic balance characteristic of the knife handle. Since a double-label symmetric installation mode is employed, the dynamic balance characteristic of the knife handle is not influenced. According to the invention, both short distance identification and long distance identification are realized, and the information of the knife-cutter flows with the circulation of the knife handle. The method also has high data security.

Description

technical field [0001] The invention relates to the field of radio frequency identification, in particular to a short-distance and long-distance identification method for a knife handle based on radio frequency identification technology. Background technique [0002] Radio Frequency Identification technology (Radio Frequency Identification) is an advanced non-contact automatic identification technology. Its basic principle is to use radio frequency signals and their spatial coupling and transmission characteristics to realize automatic identification of stationary or moving objects to be identified. [0003] A basic RFID system consists of electronic tags, readers, antennas and background systems. The electronic tag is composed of a coupling element and a chip. Each tag has a unique electronic code, which is attached to the object to identify the target object and stores the relevant information of the identified object; the reader is responsible for reading and writing the ...

AI Technical Summary

Problems solved by technology

The device uses a low-frequency frequency band, the recognition speed is low, and the recognition distance is very short, so it cannot be used in high-speed and long-distance recognition occasions, such as the inventory of tools in the tool magazine

In this identification method, the transponder is installed on the outer surface of the tool holder, which will affect the dynamic balance characteristics of the tool holder in the application of high-speed tool holders

Taking an integral tool with a HSK-A63 tool holder with a mass of 0.87KG as an example, under the condition of using the rotating speed n=15000r / min and the dynamic balance accuracy level G16, it can be known through the calculation formula of the unbalance amount that at the diameter of 63mm The remaining unbalance is only 0.2813g, and the mass of the general transponder is greater than 1g, so the installation of the transponder will affect the dynamic balance characteristics of the tool holder
