[0002] In the field of nuclear power, various types of equipment are usually controlled by distributed control systems. In actual operation, in order to ensure the correctness of the operation, there are usually two operators - an operator and a supervisor. During each operation, the operator points to the control to be operated on the safety-level DCS S-VDU touch screen with his finger and keeps it still, and reads the control code aloud. The supervisor then checks that the control pointed by the operator, the content read aloud, and the operating status of the equipment are correct before the operator can perform the corresponding operation.
