Description
Technical field
The present invention relates to field of computer technology, be specifically related to a kind of PLC ladder diagram matrix editor display packing.
Background technology
Programmable controller PLC is a kind of is specially industry automatic control and the general automaton developed.The feature such as it has that reliability is high, simple, easy to use, the perfect in shape and function of programming, versatility are good, and there is online modification function, bring good flexibility to control system.It can adapt to the requirement of different control object, magnitude control and controlling functions neatly with different configurations, be to realize " electromechanical integration " comparatively ideal opertaing device.General PLC control system is divided into two parts, and a part is programmed environment: comprise ladder diagram editor display, variable edit, engineering configures, program compilation etc.; Another part is running environment: mainly programmed environment compiling is generated project file and explain and perform.This method relates generally to ladder diagram matrix editor display.
The ladder diagram editor display section major part of PLC domestic is at present all based on external instruction interpreter, PLC ladder diagram clean up editing is become to be applicable to the tree data structure of instruction list conversion, edit the discernible instruction of complete instruction interpreter scanning ladder diagram tree-shaped list generating run environment, algorithm is complicated, efficiency is low, and trouble spot is many.
Summary of the invention
The technical problem to be solved in the present invention is: the invention provides a kind of based on PLC ladder diagram matrix editor display packing, the display of PLC ladder diagram editor is designed based on simple two-dimensional matrix, without the need to carrying out complicated syntax check, the algorithm that logic tree and traversal etc. are complicated.Substantially reduce error probability and compilation time, high execution efficiency.
The technical solution adopted in the present invention is:
A kind of PLC ladder diagram matrix editor display packing, described method operating process is as follows:
1) all logical relations of ladder diagram are described with specific text, as follows:
LAND{N,
LLD@Lib=libname,Name=componentname1,Version=componentversion,FBID=functioncode@
LLD@Lib=libname,Name=componentname2,Version=componentversion,FBID=functioncode@
……
LLD@Lib=libname,Name=componentnameN,Version=componentversion,FBID=functioncode@}

2) above-mentioned text is changed into segment, " segment " can complete certain function in ladder diagram, and have level and determine the set of a set of pieces of logical relation.
A network is made up of multiple segment, and network itself is also a segment.The segment that specific text changes into contains following information:
The coordinate of segment: X, Y;
The wide height of segment: W, H;
The function code of segment: the logical combination of contact, coil, functional module or this several module;
The logical relation of segment and other segments: "AND" logic, "or" logic;
3) describe according to logical relation change text during editor, according to the information of segment, this segment is shown to the image display area of programming tool during picture, according to the logical relation that specific text describes, all segments are shown the display namely completing LDD ladder diagram, then upgrade the editor that display can complete LDD ladder diagram.
Described figure block type is divided into: element segment, with segment or segment and mix segment, wherein:
Element segment, be an independent element, element segment is the special case of " with segment " or " or segment ", is also its branch;
With segment, only exist and relation, i.e. series relationship between element and element in segment, with the quantity N>1 of branch, and each branch is element segment;
Or segment, only exist or relation, i.e. parallel relationship between element and element in segment, the quantity N>1 of branch, and each branch is element segment;
Mix segment, forming by mixing with segment or segment and element segment, there is the segment of clear and definite logical relation generally, be called and mix segment; Mix segment and have obvious level characteristic, the combination namely mixing module can generate and more complicated mix module.
Described segment has following characteristic: logicality, level and ranks characteristic, wherein:
Logicality, only there is "AND" and "or" logical relation between adjacent elements in segment, logical relation defines the annexation in segment between element;
Level, a segment can comprise segment, and involved segment is called subgraph block, the same with segment, and subgraph block possesses the various characteristics of segment;
The ranks feature definitions size of segment, supposes that the feature size of each element is the same, and the element of composition segment is according to from top to bottom, after from left to right regularly arranged, form the matrix of the capable N row of M, by logical relation and ranks characteristic, intactly can define a network;
Utilize between segment and the logical relation of segment inside and hierarchical relationship, can realize the editor of segment and even network, concrete operations are as follows:
First to resolve ladder diagram file, by the ladder diagram file of textual form, take segment as elementary cell, resolve to the data structure with certain format, a corresponding data structure of segment, this data structure is fully described the information of this segment, comprising: the initial row column index of the data structure address pointer of figure block type, element function number, numbers of branches, branch's segment, branch's segment coordinate, element coordinate, horizontal line coordinate, vertical join line coordinate, segment, the sequence number of segment in parent segment and the annexation of segment;
Implication for dissimilar these values of segment is different, ladder diagram document analysis is become above-mentioned data structure, and by these data structures according to segment at the order of ladder diagram file and hierarchical relationship, after converting doubly linked list to, just this ladder diagram can be shown, select and be edited according to pattern information.
Described ladder diagram drawing process is as follows:
Scanning ladder diagram file, sets up doubly linked list, each node on behalf element of doubly linked list; According to the coordinate of the function code of this element and previous element in scanning process, calculate coordinate and the size of this element, the coordinate of element and dimension information are recorded to this node, and record the annexation between element; After having scanned, the doubly linked list that comprises coordinate information and annexation can be generated; The drafting of ladder diagram can be realized according to this doubly linked list.
For realizing the convergent-divergent of editing interface and ensureing display effect, three buffer technologies are taked in system display:
1) figure display buffer: its size is the network size that element does not carry out any convergent-divergent, comprises multiple network and text display area, but without text display;
2) synthesis display buffer zone: because text does not support convergent-divergent, therefore, text display buffer zone is as middle display buffer, at figure after convergent-divergent, the Set font of display handle is become corresponding size, directly be presented on the figure after convergent-divergent, form figure and the mixed synthesis display buffer zone of text;
3) output buffer: be namely finally presented at the buffer zone on interface, mainly in order to avoid screen flicker.Finally by the display of the ladder diagram that cooperatively interacted between three buffer zones.
Beneficial effect of the present invention is: the display of PLC ladder diagram editor designs based on simple two-dimensional matrix by the present invention, without the need to carrying out complicated syntax check, the algorithm that logic tree and traversal etc. are complicated, substantially reduces error probability and compilation time, improves execution efficiency.
