Abstract

The invention discloses a high-reliability fault-tolerant control device for an industrial robot, which comprises a computer, an actuator, a PLC (Programmable Logic Controller) and a machine body base, wherein the machine body base is mounted on one side of the computer; the actuator is mounted on the machine body base; the PLC is mounted on the actuator; an equipment state predictor is mounted in the PLC; a fault diagnosis device is mounted on one side of the equipment state predictor; a fault-tolerant controller is mounted on one side of the fault diagnosis device; a CPU (Central Processing Unit) is mounted on one side of the fault-tolerant controller; a first rotator is mounted on the machine body base; a fixed bracket is mounted on the first rotator; a first operation rod is mounted on the fixed bracket; a second rotator is mounted on the first operation rod; and a second operation rod is mounted on the second rotator. The high-reliability fault-tolerant control device adopts the PLC, has a fault-tolerant control function and can improve the reliability of equipment.

Description

technical field [0001] The invention relates to the technical field of high-reliability fault-tolerant control of industrial robots, in particular to a high-reliability fault-tolerant control device for industrial robots. Background technique [0002] An industrial robot is a multi-joint manipulator or a multi-degree-of-freedom machine device for the industrial field. It can perform work automatically and is a machine that realizes various functions by its own power and control capabilities. It can accept human command, and can also run according to pre-programmed programs. Modern industrial robots can also act according to the principles and guidelines formulated by artificial intelligence technology. The main task of industrial robot control technology is to control the movement position of industrial robots in the work space, Posture and trajectory, operation sequence and timing of actions, etc. It has the characteristics of simple programming, software menu operation, f...
