Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Example 1
Referring to fig. 1 to 3, an industrial control software database generating system includes a central console 100 and a plurality of real-time data acquisition devices 200, wherein the plurality of real-time data acquisition devices 200 are used for detecting different data in a production process and transmitting the detected real-time data to the central console 100, and a processing unit 300 is used for processing received electrical signals and transmitting the processed data to a storage unit 400 for storage, and is characterized in that the real-time data acquisition devices 200 are used for storing acquired data and transmitting the current acquired data to the central console 100 at regular time, specifically:

In order to improve the security of data, in this embodiment, after the data is generated in the database, the database can be automatically hidden, and an administrator can open the database by triggering a display event.
It should be noted that the triggering display event may be, but is not limited to:
operating in a preset area of the display terminal, for example, setting a certain specific area, such as the upper right corner of the display screen, on the display terminal, and judging that a triggering display event is detected when the processing unit detects that the upper right corner of the display screen is operated;
or, performing operation of a preset action in the display area, for example, a specific action, wherein the sliding track of the mouse or the finger on the display screen is the letter Z or L, and when the processing unit detects that the sliding track of the display screen is the letter Z or L, judging that a trigger display event is detected;
when the processing unit judges that the triggering display event is detected, the key is correct, and at the moment, the data in the database can be checked.
