Embodiment Construction

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0033] Such as figure 1 As shown, the vortex flowmeter diagnostic system based on artificial intelligence is divided into device end, server and web end. The device end is the vortex flowmeter itself, which is used to respond to server requests and data responses. Interaction with information on the web side and data processing operations, the web side is used for information transmission of human-computer interaction.

Abstract

The invention discloses an intelligent diagnosis method for a vortex flowmeter. The method comprises the following steps: checking the parameter setting of the flowmeter; checking the sensor failure of the meter; checking the measurement abnormality caused by the working conditions on site. The present invention is based on a web-based diagnostic human-computer interaction interface, which is intuitive and concise, and avoids the cost of maintenance personnel going to the site to check; the diagnosis and discrimination method based on the similarity algorithm has good adaptability and can reduce the professional quality requirements of maintenance personnel; Introduce the intelligent classifier judgment method of the AdaBoost algorithm. When enough training samples are accumulated and the classifier is trained with enough samples, the similarity method is no longer used for on-site sensor data analysis, and the classifier quickly outputs the diagnosis results, thereby improving the diagnosis efficiency.

Description

technical field [0001] The invention belongs to the field of vortex flowmeters, in particular to an intelligent diagnosis method for vortex flowmeters. Background technique [0002] The vortex meter uses the principle of Karman vortex street to measure the flow rate. A bluff body is inserted vertically into the pipeline. As the fluid flows around the bluff, the phenomenon of vortex separation occurs, forming a regular vortex row. The rotation direction of the vortex on both sides is opposite. This kind of vortex is called Karman vortex street. According to the above principle, people have developed a vortex flowmeter. An instrument for measuring flow. [0003] When the vortex flowmeter fails, due to its special structure, it is difficult to find the cause of the problem, which leads to great disadvantages in the diagnosis of the vortex flowmeter. In order to solve the above problems, an intelligent diagnosis method of vortex flowmeter is proposed. Contents of the inventi...
