Many functions of DCS IC system rely on threshold decision of parameters. The system state is shown by threshold and the action of reactor protection system is based on threshold. For conventional ways of threshold monitoring,data is fixed and lack of correlation with time. Multiple parameters＇ threshold decisions are not considered too. To keep the premise of security,some method of threshold monitoring and optimization are adopted,such as general data processing,filtering,floating threshold,from single parameter to multi-parameter. For the t...
