Abstract

This invention relates to robot controller CPU fault test and emergency process method, which converts the frequency signals of normal work into voltage signals through frequency transducer and enlarges the voltage signals through amplifier and the drive relay outputs indication device normal signals; when in fault, relay not outputting and indicating fault. The emergency process method is to use relay output signal to control robot output drive axis and to monitor robot work status to indicate controller CPU abnormal.

Description

technical field

[0001] The invention relates to a method for detecting the CPU crash of a robot controller and a method for emergency treatment using the detection method. Background technique

[0002] The robot controller CPU is the core of the robot control system. Its control scope includes the movement of each axis of the robot, real-time state detection and fault handling. If the CPU crashes and cannot control the robot, it may cause serious safety hazards and immeasurable losses. At present, there is no special detection method and special emergency treatment method for the crash of the robot controller CPU. It can only be detected indirectly when other control failures occur, and the problem is often not found and solved in time, resulting in serious consequences. Contents of the invention

[0003] The purpose of the present invention is to provide a kind of can detect robot controller CPU operation state in order to solve above-mentioned deficiency existing in the...
