The following two cases are specifically distinguished:
1. as shown in fig. 1a, the data migration step from the control station to the database is as follows:
a) according to the set cycle time or monitoring a trigger signal from a control station;
b) acquiring data from the control station according to the configured address area of the control station;
c) and converting the data acquired from the control station into a data format stored in the database by using an algorithm of a defined mapping function (the conversion is performed in a form of a table in a row unit), and submitting the table data obtained after the conversion into a data table specified by the database.
2. As shown in fig. 1b, the data migration step from the database to the control station:
a) according to the set cycle time or monitoring a trigger signal from a control station;
b) acquiring data from a database according to the configured sql statement;
c) converting the data tables obtained from the database into numerical data tables that can be recognized by the control station using an algorithm of a defined mapping function (the conversion is performed in units of rows in the form of tables); and sending the converted table data to an offset address designated by the control station in a row unit.
As shown in fig. 2 to 9c, the present invention further provides a configuration module corresponding to the steps 1 to 6, which includes a data source configuration module, a database data table creation and configuration module, a control station data table creation and configuration module, a mapping function compiler, and a relocation task creation and configuration module, so that the steps 1 to 6 are all implemented by means of user configuration.
Step S1, creating data sources including a database data source and a control station data source;
the data source comprises a database data source and a control station data source, and the data source is created to create a connection character string with the database or the control station. The creation mode can be entered into a right-key menu option of a node [ data source ] or [ database ] or [ control station ] in the left tree structure of fig. 2, and the created data is stored in a datasource table blade info.
(1) Create database data source (configure one SQL Server connection as an example):
selecting a node (database), popping up a menu shown in figure 3a by a right mouse button, clicking a 'new data source', popping up a configuration window shown in figure 3b, clicking a '. multidot.' button, popping up a data link attribute frame shown in figure 3c, selecting a corresponding drive (the drive of an SQL Server is selected here), switching to a connection option, configuring the name (available IP address) of a Server where the SQL database is located, the user name and password for logging in the database, selecting the name of the database to be connected, and clicking to determine after the test connection is successful. After the data source path is correctly configured, the data source path is obtained as shown in fig. 3e, and then the data source is named and then click-determined. The database data source just created will appear under the "database" node after success, as shown in FIG. 3 f.
(2) Creation of control station Source (configuration of an IAP Simu connection for example)
Selecting a node (control station), popping up a menu shown in figure 4a by a right mouse button, clicking a new data source, filling a data source name, selecting a corresponding control station type, and filling an IP address and a port number of the control station (for IAPSIU, one port number is filled at any time because the port is fixed). Pop up the configuration window as in FIG. 4 b; after the click determination, as shown in fig. 4c, the data source name just created will appear under the "control station" node,
and step S2, creating an IO variable, wherein the created IO variable is used for configuring the trigger IO, the write-back IO, the control IO and the configuration discrete data table, and certainly, if the migration task does not need the single IO points, the IO variable may not be configured. The manner of creating IO variables is shown in fig. 5a and 5b, and after determination, the IO variable points just created can be seen under the "IO variable set" node as shown in fig. 5 c.
And step S3, creating a data table, wherein the data table comprises a data table facing the control station and a data table facing the database.
(1) The data table facing the control station needs to be created under the control station source, and after the creation is successful, the table is used as a data receiving table of the control station- > IAPCCom or a data sending table of the IAPCCom- > control station. The control station data table can be divided into a continuous IO link data table and a discrete IO link data table, wherein continuous IO link refers to that a target control station of the data table is a continuous IO address field; the discrete IO link refers to the migration of each field of the data table with the specified IO point address as the target. Wherein, the process of creating the continuous IO link table is shown in fig. 6a and fig. 6b, and after the creation is successful, as shown in fig. 6c, the table name just created will be seen in the corresponding "data table set". A discrete IO link table creating process is shown in fig. 6d and fig. 6e, wherein menu options can be popped up in an IO variable management window through a right mouse button to perform operations of adding, deleting and changing IO variables; as shown in FIG. 6f, after the creation is successful, the table name just created will be seen in the corresponding "data table set".
(2) The database-oriented data table needs to be created under a database source, and after the creation is successful, the table will be used as a data acquisition table of the database- > IAPCCom (in fact, the table returned by the executed sql statement is used as the main, and the table field definition is mainly used for data conversion and needs to be consistent with the table field returned by the sql execution statement) or a data submission table of the IAPCCom- > database. Fig. 7a to 7c illustrate a process of creating a data table for reading the contents of a database table, fig. 7d to 7e illustrate a process of creating a data table for writing into a database, and after the creation is successful, the configuration data is stored in a datasource tablelnfo.
Step S4, creating a mapping function,
the mapping/converting function is mainly applied to data conversion between the control station data table and the database data table, so that the structure of the source data table and the structure of the target data table (namely, table field names) need to be known when the function is written, for example, a function is established for the previously configured TestTable2 and TestTable _ select table, and in code implementation inside the function, field data of ASourceDataSet is always assigned to a corresponding field of the adostdataset table. The creation process is shown in fig. 8a and 8 b.
Step S5, creating a migration task, and after the above steps are completed, creating a new migration task configuration, as shown in fig. 9a, selecting a new migration task, filling in the name of the migration task (only used for display in the software), selecting the type of the migration task (i.e. the direction of migration), and the interface is shown in fig. 9b and fig. 9 c.
Step S6, start the migration task, and after creating the migration task, click the start button in the main interface, and the program will start the migration task marked as "enabled", or click "start the migration task" as in fig. 10 a. If the migration task data needs to be checked, as shown in fig. 10b and 10c, click [ migration task ] - > [ migration task data monitoring ] can be clicked for checking.
Although specific embodiments of the invention have been described above, it will be understood by those skilled in the art that the specific embodiments described are illustrative only and are not limiting upon the scope of the invention, and that equivalent modifications and variations can be made by those skilled in the art without departing from the spirit of the invention, which is to be limited only by the appended claims.
