Problems solved by technology

This method compares the infrared image with the pre-built standard image of the equipment, which cannot be applied to the temperature detection of the equipment whose shape changes during operation, and there are often differences between the actually collected infrared image and the standard image. The infrared image and the standard image are accurately matched, the detection accuracy is low, or manual comparison is required, which will reduce the detection efficiency

Embodiment 1

[0019] Embodiment 1, with reference to figure 1 , a kind of industrial robot fault diagnosis method based on infrared temperature measurement, it is characterized in that: comprise the following steps:

[0020] S01. Preparatory work: set the image acquisition module and the infrared temperature measurement module adjacent to each other and align them with the robot, and adjust the positions of the image acquisition module and the infrared temperature measurement module so that the field of view captured includes the entire operating range of the robot.

[0021] S02. Construction of the actual temperature model; first build the motor model for each axis motor of the robot, and then use the image acquisition module and the infrared temperature measurement module to simultaneously shoot the robot in real time to obtain visible light images and infrared images; The motor model of each axis determines the position of each axis motor in the visible light image, and then matches the ...

Abstract

The invention relates to the technical field of robot monitoring, in particular to an industrial robot fault diagnosis method and system based on infrared temperature measurement. According to the technical scheme, an image collecting module and an infrared temperature measuring module are used for shooting the robot at the same time, the position of each shaft motor in a visible light image is determined through a pre-established motor model, therefore the position of each shaft motor in an infrared image is determined, and the real-time temperature of each shaft motor of the robot is measured; and fault diagnosis of the robot is carried out. The industrial robot fault diagnosis method and system based on the infrared temperature measurement have the advantages that the image collecting module and the infrared temperature measuring module are used for shooting the robot at the same time, the visible light image and the infrared image are combined, so that the temperature of each shaft motor of the running robot is accurately detected in real time, and the accuracy of fault diagnosis is improved; and meanwhile, the actual temperature is compared with the temperature obtained through simulation calculation, and the accuracy of robot fault diagnosis is further improved.

Description

technical field [0001] The invention relates to the technical field of robot monitoring, in particular to an industrial robot fault diagnosis method and system based on infrared temperature measurement. Background technique [0002] Industrial robots are playing an increasingly important role in manufacturing all over the world. Industrial robots can replace manpower for repetitive, single, and frequent work, and their fast and precise advantages can generate great benefits in industry. At the same time, the failure of the robot is also an unavoidable problem in the production process. Fault diagnosis and health assessment of industrial robots are an important link; the temperature of each axis motor of the robot is an important indicator for diagnosing the working conditions of industrial robots. At present, in the fault diagnosis of robots, infrared temperature measurement is mostly used to measure the temperature of the motors of each axis of the robot. However, it is d...
