System and method for lean management of dosage data of nuclear power plant

Abstract

The invention relates to a system and method for the lean management of dosage data of a nuclear power plant. The method comprises the steps that a production management workflow system generates work order task data, and transmits the work order task data to an access control system of the nuclear power plant through a unidirectional transmission module; the access control system of the nuclear power plant judges whether the work order information and worker information collected by an information collection device are valid or not: allowing a worker to enter a control region of the nuclear power plant if the work order information and worker information collected by the information collection device are valid; the access control system of the nuclear power plant records the work information after the worker complete a work order task, and transmits the work information to the production workflow management system through a second unidirectional transmission module. According to the invention, the method achieves the communication between an industrial network and a management network, enables the advantages of the production workflow management system to be applied in the access control system of the nuclear power plant, achieves the fine management of work orders and dosage analysis and statistics, and effectively reduces the conditions that the dosage exceeds a management threshold value.

Description

technical field [0001] The invention relates to the field of nuclear power, more specifically, to a lean management system and method for dose data of a nuclear power plant. Background technique [0002] Considering data security, the nuclear power plant divides the application network into two local area networks, the industrial network and the management network. On the one hand, the dose data mainly comes from the nuclear power plant access control system (KZC), and the nuclear power plant access control systems of each base are isolated from each other. Therefore, in order to integrate resources and data, these system data are uploaded to the nuclear power plant dose networking system regularly every day. (PDUS), its application is deployed on the industrial network, and the database used is oracle. [0003] On the other hand, the application system for generating and distributing on-site task work orders is completed by the production management workflow system (SAP). ...
