Embodiment

[0047] Example: A method for evaluating the reliability of an industrial robot control system. First, it is necessary to obtain the real-time active power information of the robot in a moving state per unit time, obtain the information on the force change of the robot during the movement of the robot per unit time through the power information, and establish a robot force prediction model matrix. , taking the common manipulator operation in industrial robots as an example of the evaluation object of this method:

[0048] In the detection process, a three-dimensional coordinate system is first established in the detection environment of the robot, in which a distance sensor or a position sensor is used to determine whether the robot arm has reached the detection point, and the working time between the arriving nodes is divided into several times. point, record the time it takes for the manipulator to actually reach the time point, and record it as t 0 , t 1 , t 2 ...t x (t>0...

Abstract

The invention relates to the technical field of robots, in particular to an industrial robot control system reliability evaluation method and device, and the method comprises the steps: obtaining the real-time active power information of a robot in a motion state in unit time, and obtaining the force change information of the robot in motion in unit time through the power information; a robot force application prediction model matrix is established, robot path moving node information in unit time is acquired, and a robot real-time path moment diagram is established. By measuring the displacement variable of the robot within a certain period of time and the power change of the equipment within the actual period of time, the variable of the acting force acting on the target object within the period of time is obtained, and the variable of the force applied to the target object due to the equipment reason of the robot is reflected to a certain extent; unexpected influences are brought to practical application, and the reliability of the robot can be clearly analyzed through judgment of force application of the robot.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a reliability evaluation method and a device of an industrial robot control system. Background technique [0002] Industrial robots are mechanical devices that perform work automatically. They can accept human commands, run pre-programmed programs, and act according to principles and programs formulated with artificial intelligence technology. Its task is to assist or replace human jobs, such as production, construction, or dangerous jobs. [0003] At present, industrial robots have provided a lot of convenience to major industries, but in the specific use process, confusion or deviation still occurs within a certain time node. The main reason is that the mechanical arm exerts force or moves due to certain factors. Excessive distance leads to deviations in the machining accuracy of the workpiece. Therefore, it is necessary to evaluate and test the reliability of the robot before ...
