Embodiment Construction

[0094] In order to make the purpose of the invention, technical solution and beneficial technical effects of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be emphasized that the specific implementations described in this specification are only for explaining the present invention, and are not intended to limit the application occasions of the present invention.

[0095] Please refer to figure 1 , figure 1 A method for processing massive data of a nuclear power plant is provided.

[0096] The hash value, that is, the hash value, is to convert an input of any length (also called pre-mapping, pre-image) into a fixed-length output through a hash algorithm, and the output is the hash value.

[0097] The data provider undertakes the task of obtaining data changes, improves the shadow table method, provides the changed data in the form of Ext...

Abstract

The invention discloses a method, device and system for processing mass data of a nuclear power station. The method comprises the steps of building a shadow table of a source data table, adding a hash value field to the shadow table, building a change process recording table capable of expanding an xml format according to the hash value field and issuing change process data files in the change process recording table of the xml format through a website. In the building process of the nuclear power station, transmission availability and reliability of the mass data are achieved. In addition, the invention discloses a device and system for processing the mass data of the nuclear power station.

Description

technical field [0001] The invention belongs to the technical field of nuclear power, and in particular relates to a massive data processing method, device and system of a nuclear power plant. Background technique [0002] During the design process of nuclear power plants, massive relational data will be generated and stored in large databases. Among them, the relational data of a single project may have more than hundreds of thousands of data items and more than 30 data fields, and these data and their updates need to be regularly transmitted to downstream procurement, construction, commissioning, operation and other links for use . The information systems used by all parties involved in nuclear power are built in different periods and designed by different departments, resulting in heterogeneity of the system platform; at the same time, due to the constraints of work division and information security, the design database cannot be opened to the public. All parties direct...
