As can be seen from the above background art, the existing monitoring picture WEB release mainly implements monitoring picture WEB release by parsing and reconstructing a monitoring picture. The specific process of the analysis-reconstruction is a process of subdividing the monitoring picture into the granularity of each primitive, character and object, converting the granularity of the subdivided primitives, characters and objects into a standard universal markup language description file, and reconstructing and reproducing the granularity in a WEB browser through a front-end redrawing technology of a WEB server and a data service technology at the front end of the WEB server.
However, this method needs to adopt different parsing-reconstructing strategies for monitoring pictures with different formats to implement WEB publishing of the monitoring pictures, and the publishing cost is high, and some manufacturer monitoring pictures are not published in a format that can not implement parsing-reconstructing of the pictures monitored by the manufacturer, and further cannot implement text publishing of the monitoring pictures.
Therefore, embodiments of the present invention provide a monitoring screen WEB publishing method, apparatus, and system, which can not only reduce cost, but also implement monitoring screen WEB publishing without being affected by a monitoring screen format.
It should be noted that the WEB publishing refers to a process of accessing, on a WEB server through a WEB service, content of a monitoring screen displayed in a monitoring window displayed in an industrial control terminal by industrial control software using a WEB browser client.
Referring to fig. 1, a schematic flowchart of a monitoring screen WEB publishing method according to an embodiment of the present invention is shown. The monitoring picture WEB publishing method comprises the following steps:

In the process of specifically executing step S201, the selection operation of the user on each monitoring window displayed on the current industrial control terminal means that when the user accesses the bitmap of the monitoring picture displayed in the monitoring window displayed in the industrial control terminal by the industrial control software through the WEB server by using the WEB browser client, the monitoring list including each monitoring window displayed on the industrial control terminal is first obtained, the user can determine the monitoring window of the industrial control software to be subjected to the WEB publishing of the monitoring picture by performing the selection operation on each monitoring window in the monitoring list, and after the user performs the selection operation on the monitoring window in the monitoring list, the industrial control terminal responds to the selection operation of the user on each monitoring window displayed on the industrial control terminal, so as to determine the monitoring window of the monitoring software to be subjected to the WEB publishing.
S202: and calling a window handle function in an operating system of the industrial control terminal to obtain the determined handle in the monitoring window.
In the process of specifically executing step S202, the industrial control terminal obtains, by calling a window handle function in the operating system of the industrial control terminal, a handle of the monitoring window of the industrial control software to be subjected to the WEB publishing of the monitoring screen, which is determined when the user selects and operates each monitoring window displayed on the current industrial control terminal.
In the implementation of the invention, after the monitoring window of the industrial control software of the WEB service of the monitoring picture is determined, a window handle function in an operating system of the industrial control terminal can be called to obtain the determined handle of the monitoring window, and then the bitmap of the monitoring picture displayed in the monitoring window is obtained according to the handle of the monitoring window.
In the embodiment of the present invention, step S102 disclosed in fig. 1 obtains a bitmap of a monitoring picture displayed in a monitoring serial port according to a handle of a monitoring window, as shown in fig. 3, specifically includes the following steps:
s301: and calling a bitmap information acquisition function of the operating system to acquire the bitmap information of the monitoring window.
The bitmap information comprises the bits of the bitmap corresponding to the monitoring picture.
Note that, the bit of the bitmap of the monitor screen is pixel information.
In the embodiment of the invention, the bitmap information of the monitoring window acquired by the bitmap information acquisition function of the industrial control terminal operating system is a DIB (digital information base) equipment-independent bitmap, wherein the independent bitmap is not influenced by peripheral information such as the model of equipment.
It should be noted that the bitmap information obtaining function of the operating system of the industrial control terminal may be a GetDIBits function, and may be set according to actual applications, which is not limited in the embodiment of the present invention.
In the process of specifically executing step S301, the industrial control terminal obtains specified compatible bitmap information of a monitoring picture displayed in a monitoring window displayed in the industrial control terminal by calling a GetDIBits function of an operating system of the industrial control terminal.
S302: and copying the bitmap information to a buffer area of an industrial control terminal memory.
In the process of specifically executing step S302, the industrial control terminal copies the obtained bitmap information to the buffer area of the internal memory of the industrial control terminal by calling the bitmap information obtaining function of the operating system of the industrial control terminal, where it is to be noted that the buffer area of the internal memory of the industrial control terminal is the working area of the currently operating industrial control terminal.
S303: and serializing the bitmap information in the buffer area to obtain a bitmap of the monitoring picture.
In the process of executing step S303, the industrial control terminal sequences the bitmap information in the buffer area to obtain a bitmap of the monitoring image, and specifically, maps the pixel information (bit) in the bitmap information in the buffer area to the bitmap of the monitoring image.
It should be noted that, in the embodiment of the present invention, the industrial control terminal obtains the bitmap of the monitoring screen by serializing the bitmap information in the buffer area, specifically, the industrial control terminal performs serialization processing on the bitmap information in the buffer area through "CFile" of a Microsoft Foundation Classes (MFC), that is, the pixel information (bit) in the bitmap information in the buffer area is mapped into the bitmap of the monitoring screen through the CFile "in the MFC, so as to obtain the bitmap of the monitoring screen.
It should be noted that Microsoft Foundation Classes (MFC) is a programming tool for Microsoft, and CFile "in MFC is a function for performing serialization processing.
Further, in the embodiment of the present invention, because the bitmap information of the monitoring window acquired by the bitmap information acquiring function of the industrial control terminal operating system is a DIB device independent bitmap, the bitmap information of the monitoring window only needs to be copied to the memory buffer area of the industrial control terminal, and then the pixel information (bit) in the bitmap information in the buffer area is mapped into the bitmap of the monitoring picture by the "CFile" of the MFC, so that the bitmap of the monitoring picture can be acquired.
In the embodiment of the invention, the bitmap information of the monitoring window is copied to the buffer area of the industrial control terminal by calling the bitmap information acquisition function of the operating system of the industrial control terminal, and the bitmap information in the buffer area is serialized, so that the bitmap of the monitoring picture can be obtained.
