Problems solved by technology

[0003] (1) Most of the imported software does not integrate data report software, and some software can choose to purchase additional components to realize the function of data report according to the needs of customers, but this will undoubtedly increase the cost of use for customers;
[0004] (2) Some of the imported software contains data report software, but these software have poor pertinence, and the format produced does not meet or cannot fully meet the requirements of domestic users;
[0005] (3) The domestic industrial general report software contains this part of the function, which realizes the simple data browsing function, but does not have the complex format and data statistics function;
[0006] (4) The most important thing is that commonly used configuration software requires users or development engineers to perform complex prog

Embodiment Construction

[0035] The purpose of the present invention is to realize through the following technical solutions:

[0036] The method for realizing the historical data report form without the database interface of the industrial configuration software includes the following sequence:

[0037] A. According to the user's choice, determine the type of general industrial configuration software;

[0038] B. Select the OPC / DDE interface function;

[0039] C. Real-time data collection through OPC / DDE interface;

[0040] D. Save the real-time collected data to the data buffer and wait for the extraction request;

[0041] E. According to the user's choice, set the type of data report to be generated;

[0042] F. According to the user's choice, set the data range of the data report to be generated;

[0043] G. Use the call function to retrieve data from the data saved in the buffer in step D;

[0044] H. Generate a data report according to the data retrieved in step G and the parameters set in ...

Abstract

The invention discloses a method for realizing a historical data report by breaking away an industrial configuration software database interface, comprising the following sequence: confirming the type of industrial configuration software according to the selection of a user; selecting an OPC/DDE interface function; acquiring data through an OPC/DDE interface in real time; storing the data which are acquired in real time into a data buffer and waiting for picking-up a request; setting the type of a data report to be generated according to the selection of the user; setting the data range of the data report to be generated according to the selection of the user; using an invoking function to invoke data from the data stored in the buffer; and generating the data report. After the configuration software is operated by the method, the configuration software with any format can achieve a data generating function, and types and amounts of data variables can be stored in real time and modified, deleted or increased on the basis of storage, thereby the method has the advantages of simpleness, high speed, arbitrariness and practicality.

Description

technical field [0001] The invention relates to a method for extracting data from database software, in particular to a method for extracting industrial data from any industrial general configuration software to form a report form. Background technique [0002] The current status of data reports of domestic and foreign industrial general configuration software is as follows: [0003] (1) Most of the imported software does not integrate data report software, some of which can choose to purchase additional components to realize the function of data report according to the needs of customers, but this will undoubtedly increase the cost of use for customers; [0004] (2) Some of the imported software contains data report software, but these software have poor pertinence, and the format produced does not meet or cannot fully meet the requirements of domestic users; [0005] (3) The domestic industrial general report software contains this part of the function, which realizes the...
