Abstract

The invention belongs to nuclear power design technology, and specifically relates to a back-up disk function analytic method of a nuclear power plant using a digital man-machine interface. According to the method, on the basis of principles and functions of a back-up disk, principle requirements and running requirements of the back-up disk are analyzed, then back-up disk function analysis is executed, and the back-up disk function requirements are determined with combination of requirements of running condition. At the same time, back-up disk function partition requirements are determined according to master control room actual layout, operator work distribution and back-up disk scale control targets. And then back-up disk face arrangement requirements are proposed based on the function requirements and the function partition requirements so as to guide the design, manufacture and use of the back-up disk. The back-up disk function analytic method can help to reduce frequency of an operator walking back and forth while operating the back-up disk and improve work efficiency of the operator, thereby improving security and reliability of using the back-up disk for control in the nuclear power plant.

Description

technical field [0001] The invention belongs to the technical field of nuclear power design, and in particular relates to a backup disk function analysis method of a nuclear power plant using a digital man-machine interface. Background technique [0002] For nuclear power plants using digital technology in China, the possibility of losing all computer information and control systems of the power plant must be considered in the overall design. A backup means of operation for monitoring methods. Conventional indicating instruments, indicator lights, buttons, alarm windows, etc. are installed on the backup panel. When the operation station is unavailable, the operator uses the equipment on the backup panel to monitor and control the status of the power plant, and when the operation station cannot be repaired in time, the unit can be brought to a safe backup state, and the accident can be realized under accident conditions. timely processing. As the backup of the digital oper...
