Problems solved by technology

[0009] The first problem is more difficult because of the following two reasons: 1. Thermocouples cannot be directly installed in the coating area, which will interfere with the coating, and the plasma plume generated during coating will also interfere with the test
2. Laser and other optical temperature tests cannot be used in the cavity, because the coating dust will cover the optical devices
[0010]The second problem is more difficult. The temperature of the baseband surface depends on the temperature itself when entering the coating area and the process of heat absorption and release in the coating area.
In this patent document, the repair structure needs to be realized through additional processes and equipment, and the method is complicated to realize and the cost is still high

Abstract

The present invention provides a method, system and device for controlling the temperature of superconducting tape preparation based on grayscale identification, comprising: obtaining in real time the grayscale image of the side where the film layer of the strip to be tested is located during the coating process, and converting each strip to be tested The strip is divided into multiple parts to obtain corresponding multiple grayscale values; the grayscale value of different parts is subtracted from the preset value to obtain the grayscale difference; the temperature of the coating is controlled according to the feedback of the grayscale difference, and at the When the gray scale difference is positive, the temperature of the corresponding part is decreased, and when the gray scale difference is negative, the temperature of the corresponding part is increased. The present invention controls the temperature of the preparation of the superconducting strip based on grayscale identification, can effectively feed back the coating temperature of the superconducting layer, and performs feedback control on the coating temperature according to the identified grayscale to obtain the optimal coating temperature, thereby get the best critical current.

Description

technical field [0001] The present invention relates to the technical field of superconducting strip preparation, in particular to a method, system and device for controlling the temperature of superconducting strip preparation based on gray scale identification. Background technique [0002] The second-generation superconducting strip is generally produced on a nickel-based alloy substrate by a multi-layer coating process because ReBCO, which is the core of the superconducting current-carrying core, is hard and brittle, so it is also called a coated conductor. The second-generation superconducting tape generally consists of a base tape, a buffer layer (transition layer), a superconducting layer and a protective layer. The second-generation high-temperature superconductor is a multilayer film structure, generally composed of a base band, a seed layer, an isolation layer, a cap layer (template layer), a superconducting layer, and a protective layer. [0003] This article use...
