Embodiment Construction

[0046] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0047] Explanation of terms:

[0048] HCR: Human Cognitive Reliability;

[0049] CREAM: Cognitive Reliability and Error Analysis Method;

[0050] HEC: Human Engineering Checklist.

[0051] The man-machine interface detection method of the invention is suitable for digital control systems of nuclear power plants. Since the nuclear power plant adopts digital control, there are a large number of man-machine interfaces. The man-machine interface detection method of the present invention detects the man-machine interface through the combination of HCR, CREAM and HEC methods, so as to efficiently and reliably find out the induced Deep human-machine interface flaws of human error.

[0052] refer to figure 1 , the man-machine interface d...

Abstract

The invention discloses a method and a system for detecting man-machine interfaces. The method for detecting the man-machine interfaces includes steps of identifying risk scenes where the no-response probability of actions exceeds a preset threshold value on the basis of an HCR (human cognitive reliability) process; determining error probabilities of various tasks or the various actions in the identified risk scenes by a CREAM (cognitive reliability and error analysis method); and sequentially checking the man-machine interfaces involved in the various tasks or the various actions with a preset human engineering checklist according to magnitudes of the error probabilities to determine defective man-machine interface units. The method and the system have the advantages that the digital man-machine interfaces of a nuclear power plant are evaluated by the HCR, CREAM and HEC (human engineering checklist) combined method, and the defective man-machine interface units in the digital man-machine interfaces are quickly and efficiently detected, so that deep-seated design defects which cause human errors can be found, and the running safety of a digital control system of the nuclear power plant is integrally improved.

Description

technical field [0001] The invention relates to the field of digital control of nuclear power plants, in particular to a human-machine interface detection method and system applied to digital control of nuclear power plants. Background technique [0002] Nuclear power plants (NPPs) are complex high-risk systems. Due to the accidents at Three Mile Island and Chernobyl, people have realized the importance of human-computer interaction, and the human-machine interface (Man-machine interface, The quality of the MMI) design is critical to human performance and nuclear safety. For example, Smith and Mosier pointed out in the article "Guidelines for designing user interface software" in 1986: Data processing from a bad human-computer interface will lead to frequent and serious human errors; Bellamy and Geyer in 1988 in " Addressing human factors issues in the safe design and operation of computer controlled process systems” also researched that nearly 60% of the events in computer...
