Method and system for arranging digital human-machine interface monitoring units

Abstract

The invention discloses a method and a system for arranging digital human-machine interface monitoring units. The method includes performing parameter coding on a plurality of human-machine interface monitoring units according to characteristic values of the monitoring units; creating initialization groups according to a sequence of the monitoring units after parameter coding is performed on the monitoring units; evaluating the groups by a process for calculating error probabilities on the basis of an objective function of a Bayesian network to acquire monitoring human error probabilities corresponding to the groups; judging whether the monitoring human error probabilities acquired by means of evaluating the groups tend to be stable or not, creating new groups which represent an evolved sequence of the monitoring units by a genetic hybrid algorithm if the monitoring human error probabilities do not tend to be stable, or terminating an evolution procedure if the monitoring human error probabilities tend to be stable; and comparing the monitoring human error probabilities which are acquired in multiple group evaluation procedures and correspond to the multiple groups, and selecting the group with the minimum monitoring human error probability as the optimal sequence of the human-machine interface monitoring units so as to acquire the optimal arrangement of the human-machine interface monitoring units.

Description

technical field [0001] The invention relates to the field of digital control of nuclear power plants, in particular to a layout method and layout system of digital man-machine interface monitoring units for digital control of nuclear power plants. Background technique [0002] The operator obtains information on the current operating status of the factory through the man-machine interface, and performs corresponding actions after making judgments and decisions based on the obtained information. Experience shows that the quality of human-computer interface design will affect a series of behaviors such as information acquisition and judgment. Among the accidents in the digital control system, the accidents caused by human factors have taken the main position, and human-induced accidents have become the main source of accidents in nuclear power plants and chemical plants. For example, 60%-90% of system failures are attributed to human factors. Misoperation; In 1995 US statisti...
