DCS I/O Allocation Based On Bisecting K-Means Algorithm

Distributed Control System(DCS)is one of the mainstream option for industrial instrument and control system.This paper has studied the DCS I/O allocation problem caused by the mass signals utilized in large-scale industrial facilities such as nuclear power plants' DCS system,including the allocation principle,manual allocation process and its deficiencies.The study indicates the manual allocation process is low-effective,error-prone,and not optimized.In order to improve system safety,reduce engineering cost and improve system maintainability,this paper models the I/O allocation problem based on grouping algorithm and establishes evaluation indicators for allocation results.Then solves the grouping problem uses bisecting K-Means algorithm,with specific improvements in I/O allocation prolbems.The research result was then put into practice and achieved satisfying results.
