Problems solved by technology

However, when drawing and modifying the page, it is impossible to ensure that the order of new and deleted connection lines in the factory and on site is consistent. When the variable names of the intermediate connection lines are automatically named in the drawing stage according to certain rules, the naming of the connection lines is caused by the inconsistent drawing order. Different, so the formed connection variable names may be different, resulting in the formation of C code products or compiled object files may be different

Embodiment Construction

[0024] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings. Visual page program modification consistency verification method and steps are as follows: figure 1 Shown: Calculate the intermediate information text and CRC1 of the visual page A modified by the manufacturer; calculate the page A’ and 32 modified by the on-site technical support personnel as CRC2, and compare whether CRC1 and CRC2 are consistent, and draw the conclusion of page modification consistency. Among them, forming the intermediate information text of the page is a key step, and the specific implementation is as follows:

[0025] 1) Read the visualization page file, including symbol data such as input symbols, output symbols, functional function symbols, and connecting lines;

[0026] 2) Through the connection start symbol ID, connection termination symbol ID, connection start variable name, and connection termination variable name...

Abstract

The invention discloses a visualization page program modification consistency verification method. The visualization page program modification consistency verification method comprises the steps that middle information text of a page is formed according to the relation of input and output data streams between symbols in the visualization page and data type information, wherein the middle information text is formed by splicing key content such as output variable names and variable types input outwards by the page, input and output formal parameter types and parameter set values of related symbols and data stream call expressions of output variables; CRC is formed through calculation based on the middle information text and serves as a feature code of the page, and the result of whether the page program modification is consistent or not is given by comparing feature codes between the internal modification page in a factory and a field project modification page. By means of the method, the problems that when page file differences caused by position deviation, middle variable naming differences, uncorrelated connector network sequence changes and the like exist, practical functions are misjudged to be inconsistent when consistent can be effectively solved.

Description

technical field [0001] The invention belongs to the field of visual programming, and in particular relates to a method for checking consistency of visual page program modification. Background technique [0002] For the DC input control protection and flexible transmission protection projects that have been put into operation, when there are new requirements, some visual page programs need to be modified. First, the R&D personnel modify the relevant programs in the manufacturer, and after completing the relevant tests in the manufacturer and passing the review and review, the modified pages and modification procedure documents are sent to the site. Afterwards, the technical support personnel check out the page to be modified from the on-site program server, modify and compile it according to the modification instructions, and download it to the device. The on-site server is isolated from the network, does not allow port operations such as USB, and does not allow directly ove...
