Embodiment Construction

[0024] This embodiment is a blade fault diagnosis test device based on visual information processing.

[0025] Firstly, the rotating blades needed for the test are selected and pretreated according to the test requirements. Then connect the rotating blade to the rotating shaft through blade fasteners, confirm that all test devices are connected correctly and the wires are connected correctly, and the test device is firmly connected to the fixed table. Turn on the speed cameras and get ready to work. Start the servo motor, set the operating parameters of the servo motor; the servo motor drives the rotating shaft to rotate, and obtain the visual information of the surface of the rotating blade through the high-speed camera. Finally, use the computer to process the picture information obtained by the high-speed camera, and carry out fault diagnosis and analysis on the rotating blade.

[0026] refer to Figure 1 ~ Figure 3 , the present embodiment is based on the blade fault di...

Abstract

The invention discloses a blade fault diagnosis test device based on visual information processing. The test device comprises a test bench, a motion assembly, a rotary blade, an information acquisition system, a fixed platform and a computer. The test bench is fixedly connected to the fixed platform through a bottom plate. The information acquisition system is arranged at one opposite end of the test bench and realizes axial sliding adjustment along the fixed platform by a bracket. A bearing frame is arranged at the inner side of the test bench and is fixedly connected with the bottom plate bya bolt. The information acquisition system uses a high-speed camera as a visual signal acquisition component and acquires visual information; the high-speed camera shoots a picture of the rotary blade in a rotating state and transmits the picture to the computer for fault diagnosis analysis; a servo motor drives a rotating shaft to rotate and the rotating shaft drives the blade to make rotation by a blade fastening member to simulate different working states of the rotary blade. The test device has advantages of simple structure and high processing precision; and a reliable test platform is provided for the fault diagnosis of the rotary blade.

Description

technical field [0001] The present invention relates to the application of visual information processing and fault diagnosis technology, in particular to the application of visual information processing technology to the fault diagnosis of blades in a rotating state, the real-time monitoring of blade surface states, and the diagnosis and prediction of fault information. Background technique [0002] With the development of modern industrial technology, the structure of modern equipment is becoming more and more complex, and facing changing working conditions, higher requirements are placed on product safety and reliability. Therefore, fault diagnosis technology has become an important way to ensure the safe and reliable operation of modern equipment. means. Fault diagnosis technology is mainly to judge the nature, category, degree, cause, location and consequence of the fault and to provide guiding opinions on the fault handling method. [0003] As a key component of many m...
