Study on Human-Machine Interface Design of Nuclear Power Plant Control Room

The first generation of nuclear power plant control room is mainly based on analog technology. The second-generation control room is a "hybrid" control room combing analog technology and digital technology. The third-generation control room is based on digital technology. Although its digital human-machine interface can achieve the functions that cannot be achieved by the first and second generations of human-machine interfaces, its number of alarms is higher than those of the two previous generations of nuclear power plants. At the same time, the digital alarm display mode is not as intuitive as the conventional light card display mode. If the alarm list is too long, it will cause certain interference to the operator to handle important alarms. In order to solve the above problems, it is necessary to appropriately " suppress" the alarms that the operator does not have to pay attention to, so that they do not appear in the alarm list, so as to reduce the burden on the operator, in addition, it can provide technical reference for the design of human-machine interface in the subsequent nuclear power plant control room.
