Brake error prevention device and control method for preventing misoperation in limited space operation

Abstract

The invention relates to a braking error prevention device and a control method for preventing human error operation of safety protection for limited space operators, belonging to the field of equipment management. The brake anti-error device comprises a display, a face recognition system, a work card, a work card storage device, a controller, an electronic control switch and a solenoid valve forcontrolling a pipeline. The method comprises the following steps: 1) closing the corresponding valves and cutting off the power supply lines of the valves; 2) carrying out face recognition; 3) removing and carrying a working tag; 4) carrying out face recognition; 5) displaying a face recognition result; 6) executing the corresponding content according to the face recognition result; 7) recoveringthe working tag; 8) executing the corresponding content according to the working tag recovery result; and 9) restoring the system.

Description

technical field [0001] The invention belongs to the field of equipment management, and in particular relates to a brake misoperation prevention device and a control method for preventing misoperation in limited space operations. technical background [0002] Electric, pneumatic and manual valves are used as isolation equipment for connecting pipeline systems in limited spaces of power generation companies or other enterprises. Such isolation valves have terrible hidden dangers of misoperation accidents. Especially in the maintenance operation of the limited space isolated by closing the valve in the operating equipment or system, if the operator makes a wrong operation or accidentally opens the valve during the inspection and elimination operation of the maintenance personnel, the consequences will be unimaginable and very easy Causing vicious personal injury accidents to workers. [0003] On February 23, 2016, the major accident involving the death of 3 people in Changshan...
