It should be noted that, because of the little interactive capability of the PLC system, it is not very friendly if any because of the display contents, so it is not convenient for the field operator to know the specific situation of the robot system. The robot expert system can thus make up for the associated deficiencies. The specific execution steps are as follows:
after a button for starting the robot function is pressed, whether the starting conditions of the robot are met is judged firstly, such as whether the robot is in the original position, whether the limiting signal is normal, whether the gas pressure on the site is normal and the like.
When the robot cannot continue to follow up the running track, a prompt is given on the picture, so that the field operator can be reminded of what happens conveniently, and how to solve the problem in the follow-up process.

It should be noted that, after the robot is debugged, the torque of the motor is tested when the robot runs in the full orbit. As a rule of thumb, the torque cannot exceed 50% of the maximum value when the robot is in operation. If the normal torque is 35%, the maximum torque is set to 55%. When the torque exceeds 55%, the robot stops in time, alarm information can be given, and an expert system can give an overrun alarm about which axis of the robot is specified.
In another embodiment of the present invention, the operation and maintenance system determines whether the robot completes the process normally according to the process signal, and can determine the reason for the process interruption.
