Embodiment 1

[0062] Example 1: The overall layout of the algorithm page

[0063] Establish an algorithm configuration algorithm page with complete logic functions, and each algorithm page includes a logic configuration area, a static icon description area, and an edit, review, and signature area. The logic configuration area is used to place the elements required by the DCS logic algorithm, such as input variables, output variables, and algorithm blocks; the static icon description area places some static description icons, which can visually represent the physical meaning of the current relevant input and output variables; editing and proofreading Editing, proofreading, and signature information are placed in the review and signature area. The logic configuration area is the core of the actual logic configuration function.

[0064] When the user drags and drops, only input and output variables and algorithm block data can be dragged to the logical configuration area, and static descripti...

[0066] Example 2: Input variable and output variable layout

[0067] Such as image 3 As shown, the elements in the logic configuration area are composed of input variables, output variables and logic algorithm blocks. Input variables, output variables and logic algorithm blocks are displayed in rectangular boxes.

[0068] Establish a coordinate system in the two-dimensional space of the algorithm page, take the horizontal direction of the visible rectangular frame as the X axis, take the vertical direction of the rectangular frame as the Y axis, and image 3 The upper left of the rectangular box of the logical configuration area shown in is the origin of the coordinate system.

[0069] For the convenience of users, when input variables and output variables are put into the configuration area by dragging and dropping, follow the user's input and output principle from top to bottom, arrange the input variables on the top of the rectangular box in the logical configuration are...

Embodiment 3

[0077] Embodiment 3: automatic connection between variables and variables, variables and algorithm blocks

[0078]Input variables, output variables and algorithm block pins all have their own types, usually one input and output variable is one type. The algorithm block has multiple input and output pins, and each pin has been determined as a type, and the pins are further divided into input and output pins, which are respectively connected to input and output variables. Input variables can also be directly connected to output variables.

[0079] Such as Figure 4 As shown, when the input variables and the algorithm block are selected, the number and type of the input pins of the algorithm block are compared with the input pins of the algorithm block from top to bottom according to the number and order of the input variables. If the number and type are consistent, automatic connection can be performed.

[0080] When the output variable and the algorithm block are selected, t...

Description

technical field [0001] The invention relates to the technical field of nuclear power plant safety level DCS, in particular to a processing method for element layout and connection of an algorithm page in a DCS logic algorithm diagram. Background technique [0002] For the engineer station software of the nuclear power plant DCS platform, the algorithm configuration software is its core function, and it is the man-machine interface for the user to build the logic function of the entire DCS control system. [0003] In actual projects, the logic of the DCS control system is usually relatively complex, with dozens or even hundreds of algorithm pages, and there is a relatively close relationship between the algorithm pages. In order to perform logic algorithms, it is necessary to first put each element into the algorithm page, and then associate each element according to a certain logic, so that subsequent logic operations can be performed. In the process of putting each element...
