Embodiment Construction

[0068] The invention will be described in further detail below with reference to the accompanying drawings.

[0069] In a typical configuration of this application, the terminal, the equipment serving the network and the trusted party all include one or more processors (CPUs), input / output interfaces, network interfaces and memories.

[0070] Memory may include non-permanent memory, random access memory (RAM) and / or non-volatile memory in computer-readable media, such as read-only memory (ROM) or flash RAM. Memory is an example of a computer readable medium.

[0071] Computer readable media, including permanent and non-permanent, removable and non-removable media, can realize information storage by any method or technology. Information can be computer readable instructions, data structures, modules of programs or other data. Examples of computer storage media include, But not limited to, phase change memory (PRAM), static random access memory (SRAM), dynamic random access memory (...

Abstract

The invention aims to provide the steel ladle surface fault diagnosis method and equipment, the defects in the prior art are overcome, the automatic detection precision of the steel ladle surface fault is improved, particularly, the detection rate of tiny faults is improved, and meanwhile, the detection efficiency of the steel ladle surface fault is ensured. Unlike defect data used in the prior art, the temperature trend curve obtained through fitting is used for calculating the temperature normal value interval, whether the steel ladle is normal or not is judged through the interval range, and the problem that positive and negative samples are unbalanced is solved.

Description

Technical field [0001] The invention relates to a ladle surface fault diagnosis method and equipment. technical background [0002] Generally, ladle refers to molten steel ladle, which is used for steel mills and foundries to take molten steel and pour it before open hearth, electric furnace or converter. During the operation of ladle, the long-term contact with high-temperature molten steel and slag will shorten the service life of ladle lining. According to experience, ladle slag pouring surface (ladle wall), trunnion position and ladle bottom position are prone to failure. If these three faults occur, the safety performance of ladle will be seriously affected, and the molten steel will splash and the ladle will break. Therefore, it is of great significance to monitor the surface quality of ladle in real time. At present, the common detection method is to use temperature measuring gun for single-point temperature detection, and to determine whether ladle repair is needed by det...
