Digital man-machine interface monitoring unit layout method and layout system

Abstract

Disclosed are a layout method and system for monitoring units of a digital man-machine interface. The method comprises: conducting parameter coding on a plurality of monitoring units of the man-machine interface in accordance with characteristic values of the monitoring units; building an initialized group in accordance with a sequence of the monitoring units after the parameter coding; conducting group evaluation on the basis of an error probability calculation method of Bayesian network objective functions to obtain monitoring human error probabilities corresponding to the group; judging whether the monitoring human error probabilities obtained by the group evaluation trend to be stable, if not, using a genetic hybrid algorithm to rebuild a new group which represents the sequence of evolved monitoring units, and if yes, terminating the evolution process; and comparing the monitoring human error probabilities corresponding to a plurality of groups obtained by multiple group evaluations, and selecting a group with the minimum monitoring human error probability as an optimal sequence of the monitoring units of the man-machine interface, thereby obtaining an optimal layout of the monitoring units of the man-machine interface.

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...
