Embodiment Construction

[0020] The technical solutions of the present invention will be described in further detail below through specific implementation methods.

[0021] like figure 1 Shown, 1, a kind of generation method based on the PLC ladder diagram of generating set controller, it comprises the following steps:

[0022] Step 1: Define the type of intermediate tree nodes, the intermediate tree nodes include leaf node X, series node S and parallel node P, the leaf node X is the logic node switch in the ladder diagram, the series node S and parallel node P is the parent node of the logic node in the ladder diagram; define the logic node type, wherein, the logic node represents the specific content of each node on the ladder diagram;

[0023] Step 2: Build an intermediate tree, which is achieved through the following steps:

[0024] Step 2.1: Drag a logical node to the interface. If there is only one logical node on the interface, create a new logical node X1 without relationship nodes, and then...

Abstract

The invention provides a generator set controller based PLC (programmable logic controller) ladder diagram generation method. The method includes three steps of defining types of intermediate tree nodes, structuring an intermediate tree, and traversing the intermediate tree to generate a ladder diagram. The relation among logic nodes is found by the method of structuring the intermediate tree, and then the intermediate tree is traversed to draw the ladder diagram; the method has the advantage of flexibility and simplicity in operation.

Description

technical field [0001] The invention relates to a method for generating a ladder diagram, in particular to a method for generating a PLC ladder diagram based on a generator set controller. Background technique [0002] PLC programming methods generally use five kinds of ladder diagram language (LD), instruction list language (IL), function block language (FBD), sequential function flow chart language (SFC) and structured text language (ST), among which the ladder diagram language (LD) is the most simple and intuitive. However, the existing ladder diagram editing software has the disadvantages of being inflexible and prone to errors when editing ladder diagrams. [0003] In order to solve the above existing problems, people have been seeking an ideal technical solution. Contents of the invention [0004] The purpose of the present invention is to aim at the deficiencies in the prior art, thus provide a kind of operation flexible, simple, can use the mouse to arbitrarily d...
