Embodiment Construction

[0035] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0036] The data points in the nuclear power plant simulator include two main types, one is the physical quantity that needs to be simulated, such as the flow rate, pressure, temperature, etc. of the medium in the loop pipeline; the other is the equipment that needs to be simulated in the simulator, such as valves Wait. Among them, physical quantities have parameter values, such as temperature, including initial temperature, temperature range, etc.; while equipment has multiple technical parameters, such as valves, including valve type, specification, applicable temperature and applicable medium, et...

Abstract

The invention discloses a data storage, inquiry and updating method for a nuclear power plant analog machine and a initializing method of the nuclear power plant analog machine. The data storage method is used for storing multiple data points of the nuclear power plant analog machine, and each data point has multiple attributes. The data storage method includes: building a storage structure which comprises a plurality of addresses; building a plurality of hash tables; wherein one data point is correspondingly stored at one address, each hash table uses the same attribute of multiple data points as a key and the corresponding multiple addresses as the value. By the data storage method, categorized storage based on attributes of data points and using the hash tables is achieved, and huge and complex data points become order and clear. In addition, a user can flexibly modify, increase and delete data points and attributes thereof according analog status, so that the storage method is flexible and suitable for requirements of the analog machine.

Description

technical field [0001] The invention relates to data storage, query and update methods, in particular to a data storage, query and update method applied to nuclear power plant simulators. Background technique [0002] The nuclear power plant full range simulator (referred to as the nuclear power plant simulator) is a system that simulates the operation of the operator in the nuclear power plant. There are a lot of data in the nuclear power plant simulator, some of which are the actual physical quantities generated during the operation of the power plant simulated by the simulator, such as the temperature and pressure of the medium in a loop pipeline of the nuclear power plant; Intermediate variables created in the system. These data can be collectively referred to as data points here, and there are usually tens of thousands of data points in the full-scale simulator system of a nuclear power plant, and the number is quite large. In addition, the full-scale nuclear power pl...
