Embodiment Construction

[0022] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings. It should be noted that the implementation of file-type historical data and memory-type real-time data in the access control system based on the open database interface according to the present invention is only an example, but the present invention is not limited to this specific implementation.

[0023] Such as figure 1 As shown, a system based on file-type historical data and memory-type real-time data in the open database interface access control system of the present invention is mainly composed of a data service module, a data abstraction module and an open control system database interface module. The data service module is further divided into file-type historical data service components and memory-type real-time data service components.

[0024] Among them, the data service module provides support for accessing t...

Abstract

The invention discloses a system for accessing a file type history data and a memory type real data in a control system based on an open type database interface for realizing data access to the file type history data and the memory type real data in the control system by way of accessing database. The system includes a data serve module, a data abstract module and an open type control system database interface. The invention also discloses a method for accessing the file type history data and the memory type real data in the control system based on the open type database interface. The system and method provided by the invention can stimulate the file type history data and the memory type real data in the control system into two data tables in a relationship database: a history data table and a real data table. The system and the method provided by the invention can realize data accessing to the file type history data and the memory type real data in the control system by way of accessing database that is convenient for accessing the file type history data and the memory type real data in the control system.

Description

technical field [0001] The invention relates to a data access method in a computer application system, in particular to a method and system for accessing file-type historical data and memory-type real-time data in an open database interface-based access control system. Background technique [0002] At present, there are various real-time control systems in enterprises in our country, but all kinds of real-time control systems are generally a relatively independent production system in the enterprise, and there is no data information sharing with the management system and information system of the enterprise. 1. It is difficult to obtain all kinds of production data required in the information system, which makes the production and management of the enterprise divided into two large parts. benefit. [0003] The general real-time data in the existing real-time control system are memory type, and the historical data are all in the form of files. In terms of real-time data and ...
