Problems solved by technology
At the same time, for each manufacturer, the division of labor in software development is becoming more and more detailed, and it is difficult for developers to cover all professional directions. Some software developers are familiar with computer research, but not deeply involved in relay protection and measurement and control principles; and Some developers are experts in the field of relay protection, but there is not much research on software development
Therefore, no matter the developer who is familiar with computer programming technology or the principle of relay protection, they cannot fully check the developed program, and cannot fundamentally guarantee the correctness of software logic

Embodiment Construction
[0035] The present invention will be further described below in conjunction with the accompanying drawings.
[0036] Adjacency Matrix: It is a matrix that represents the adjacent relationship between vertices. Let G=(V,E) be a graph where V={v1,v2,...,vn}. The adjacency matrix of G is a square matrix of order n with the following properties:
[0037] ① For undirected graphs, the adjacency matrix must be symmetric, and the diagonal must be zero (only undirected simple graphs are discussed here), but this is not necessarily the case for directed graphs.
[0038] ②In an undirected graph, the degree of any vertex i is the sum of all elements in the i-th column; in a directed graph, the out-degree of a vertex i is the sum of all elements in the i-th row, and the in-degree is the sum of all elements in the i-th column of and.
[0039] The number of non-zero elements in the i-th row in the directed graph adjacency matrix is the out-degree of the i-th vertex, the number of non-ze...

The present invention relates to a programming method based on an adjacency matrix logic diagram execution order and feedback decoupling, the method is as follows: 1) the user customizes the basic logic graphics elements required for the operation of the equipment according to the control logic requirements of the equipment; 2 ) Use the basic logic primitives to complete the programming of the logic diagram; 3) The program software reads the primitive information and generates a two-dimensional array of vertex vectors and the relationship between vertices; 4) Uses the adjacency matrix feedback loop to execute the algorithm to obtain the logic Logical relationship in the figure; 5) Use the XML generator to generate a logical tree XML file that can be read by the device program; 6) The device runs the device application program according to the logical tree XML file. The invention can realize graphical programming of logical relations of relay protection devices, measurement and control devices and other intelligent devices.
Description
technical field [0001] The invention belongs to the field of power system computer applications, and relates to a program application for determining the execution order of interdependent tasks, in particular, to a programming method based on an adjacency matrix-based logic diagram execution order and feedback decoupling. Background technique [0002] At present, with the continuous upgrading of the construction of the smart grid, users have put forward requirements for intelligent analysis, intelligent alarm, and sequential operation of relay protection devices, measurement and control devices, and other intelligent equipment. Domestic manufacturers and scientific research institutions have also invested a lot of Manpower to carry out smart grid protection research. At the same time, for each manufacturer, the division of labor in software development is becoming more and more detailed, and it is difficult for developers to cover all professional directions. Some software d...
