All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
Referring to fig. 1, an embodiment of the present invention provides a screen monitoring system, including: the system comprises a first terminal, a second terminal and a server corresponding to a preset page.
The first terminal installs and starts a server program of the real-time screen monitoring system. The second terminal installs and starts a client program of the real-time screen monitoring system. The user can access the preset page through the browser of the first terminal, and send a command requesting to monitor the preset page through the screen of the second terminal to the server corresponding to the preset page, for example, a button of "large screen up" is set in the preset page, and the user realizes interaction with the server corresponding to the preset page by clicking the button of "large screen up". Therefore, the first terminal can communicate with the server corresponding to the preset page. In addition, the server corresponding to the preset page can adjust the page layout of the preset page and the pixels occupied by each component.
Referring to fig. 2, an embodiment of the present invention provides a screen monitoring method, including:
s201: the first terminal acquires the screen resolution of the second terminal.
S202: and the first terminal sends the user request to a server corresponding to the preset page through an instruction of monitoring the preset page by the screen of the second terminal.
The instruction carries the screen resolution of the second terminal.
S203: when a server corresponding to the preset page receives an instruction sent by a first terminal and used for a user to request to monitor the preset page through a screen of a second terminal, description information of the preset screen monitoring area is calculated according to the screen resolution of the second terminal, the resolution of the first terminal and position information of the preset screen monitoring area in the preset page.
The description information is used for enabling the first terminal to obtain a bitmap with the same resolution ratio and the same length-width ratio as the screen resolution ratio of the second terminal when the first terminal captures a screen in a preset screen monitoring area in a preset page displayed on a screen of the first terminal.
S204: and the server corresponding to the preset page replies the description information to the first terminal.
S205: and the first terminal receives the description information replied by the server and captures a preset screen monitoring area in a preset page presented on the screen of the first terminal according to the description information.
S206: and the first terminal sends the screen capture result to the second terminal.
S207: and the second terminal receives the screen capture result sent by the first terminal, adjusts the screen capture result according to the resolution of the second terminal, and presents a preset screen monitoring area through a screen of the second terminal.
Before performing S201, the first terminal establishes a connection with the second terminal through the IP of the second terminal.
When the first terminal establishes the TCP connection with the second terminal, the following methods may be adopted, but are not limited to:
specifically, Java object-oriented connection generally goes through the following 4 basic steps: (1) creating Socket and establishing connection; (2) opening an input/output stream connected to Socket; (3) performing read/write operation on the Socket according to the protocol; (4) and closing the Socket.
2 classes in the net package: socket and serverssocket, which respectively represent a client (second terminal) and a server (first terminal) of a connection. Referring to fig. 3, the server uses serversocket (port) to bind the local Socket to the port and wait for connection. A client creates a designated port for Socket connection to a server by using Socket (port), and when the server monitors a connection request, the server uses accept () to successfully establish a connection.
For step S203, the description information is obtained by the server through calculation according to the screen resolution of the second terminal, the resolution of the first terminal, and the position information of the preset screen monitoring area in the preset page, and the description information includes the position coordinate of the preset screen monitoring area and the resolution of the preset screen monitoring area, where the resolution of the preset screen monitoring area and the screen resolution of the second terminal have the same aspect ratio.
The following takes an emergency broadcast page as an example to illustrate how to determine the description information of the preset screen monitoring area. Referring to fig. 4, the emergency broadcast page includes a left menu, an upper head-up, and a right operation area, wherein the operation area is a preset screen monitoring area. The top head-up width is 126, which refers to the distance between the upper boundary of the operating region and the upper edge of the page. The length of the left menu is 10% of the width of the page display screen.
The screen resolution of the first terminal is 1920 × 1080, the screen resolution of the second terminal is 1600 × 900, that is, 16:9, the width of the operation area is 1080-.
The coordinates of the upper left corner of the operating area are:
x is 1920 × 10 ═ 192, where 1920 × 10% is the length of the left menu, and y is 126.
And the server takes the calculated coordinates of the upper left corner of the operation area and the size of the operation area with the same length-width ratio as the screen resolution of the second terminal as the description information of the preset screen monitoring area and sends the description information to the first terminal.
As can be seen from the above, for the layout of different preset pages, because the preset screen monitoring area is located at different positions in the preset page, when the description information of the preset screen monitoring area is calculated, the description information may be the coordinates of the upper right corner or the coordinates of the lower right corner, but the processing method is similar to the above example, the principle is the same, and details are not repeated here.
And S206, the first terminal encodes the bitmap information obtained by screen capture into a data stream by JPEG compression and transmits the data stream to the second terminal.
For example, a Robot in Java provides a createscreencapture (rectangle) method to capture a screen, creates a rectangle object according to the position coordinates of a preset screen monitoring area given by a server corresponding to a preset page, and copies pixels of the preset screen monitoring area into a buffer image object, thereby completing the screen capture. Then, the object is JPEG-encoded and compressed and written into the Socket output stream.
And for S207, the second terminal reads Socket input stream data connected with the TCP, decodes the Socket input stream data to obtain a screen capture bitmap of the server, and finally displays the bitmap in JPanel of the AWT.
For example, in the above example, referring to fig. 5, if the resolution of the operation region is 1696 × 954 and the screen resolution of the second terminal is 1600 × 900, the operation region is enlarged to 1600 × 900 in an equal scale and displayed on the screen of the second terminal.
Referring to fig. 6, a screen monitoring execution process inside the first terminal and the second terminal is shown. The first terminal obtains an image stream through screen capture, the image stream is subjected to JPEG coding compression, the coded and compressed data is transmitted through a TCP protocol, the second terminal decompresses the received data through JPEG coding to obtain an image stream, and the image stream subjected to equal-proportion adjustment is displayed through a large screen.
Based on the same inventive concept, the embodiment of the present invention further provides a device for screen monitoring, and as the principle of the device for solving the problem is similar to that of the method embodiment, the implementation of the device can refer to the implementation of the method, and repeated details are not repeated.
