Embodiment Construction

[0031] The following is an implementation of an actual case of the present invention, and the purpose and characteristics of the present invention can also be seen from the description of the case. It should be understood that the examples described here are only used to illustrate and explain the present invention, not to limit the present invention.

[0032] Provide engineering and technical personnel with an fbd function block diagram editing interface to edit the logical relationship diagram of the fault diagnosis system. When saving, load the function blocks and logical network relations of the fbd diagram, perform topology sorting, and store the function block settings and logical relations in the database.

[0033] Check the connection of function blocks before sorting the logic network topology: formulate the connection rules as follows: only input and output ports are allowed to be interconnected; port connections are distinguished according to the type of data flow, ...

Abstract

The invention discloses a logic network topology sorting and storing method for a fault diagnosing system, which comprises the following steps: 1) performing topology sorting on a complicated topology structure which represents a logic relationship, wherein a complicated fault diagnosing logic which accords with an IEC61131-3 standard and is represented by a functional block principle chart fbd is a directed cyclic structure that comprises a directed tree-shaped structure and multiple feedback rings; 2) respectively establishing two kinds of tables in a database, namely a function block information table and a fault tree logic relationship table, wherein the function block information table describes the detailed attribute and executing information of each function block, the fault tree logic relationship table describes connecting relationship among the function blocks and sorting grade of the function block, and the tables are correlated through key words; and 3) according to the content of relationship tables of the function block in the database, directly generating a fbd chart which accords with an IEC61131-3 standard. The logic network topology sorting and storing method can reduce cost of a fault diagnosing system and realizes flexible configuration and reliable operation of the system.

Description

technical field [0001] The invention relates to a logic network topology sorting and data storage method of a fault diagnosis system, belonging to the field of automatic control. Background technique [0002] Various automation industries in my country are in a period of rapid development.
