Referring to fig. 1, a method for controlling screen display content provided by the embodiment of the present invention includes:
step S110: receiving a display content switching instruction sent by a control end, an identification code of an object to be controlled and an identification code of content to be displayed;
in this embodiment, the object to be controlled may be a display screen on which a browser is installed, the identification code of the object to be controlled may be a machine code of the object to be controlled, and the identification code of the content to be presented may be an ID of the content to be presented.
Step S120: finding the content to be displayed in a preset database according to the identification code of the content to be displayed;
step S130: sending a display content switching instruction to the object to be controlled according to the identification code of the object to be controlled;
it should be noted that, the sequence of step S120 and step S130 may be interchanged, that is, an instruction for switching the display content is first sent to the object to be controlled according to the identification code of the object to be controlled, and then the content to be displayed is found in the preset database according to the identification code of the content to be displayed, which is not limited in this embodiment of the present invention.
Step S140: receiving a data request sent back by an object to be controlled;
step S150: and sending the content to be shown to the object to be controlled.
In order to modify the playing time interval between the signboards in the display content at will, the method further comprises the following steps:
receiving a playing time interval modification instruction between the signboards in the display content, the display content identification code and the modified playing time interval;
finding out corresponding display content in a preset database according to the display content identification code;
and modifying the playing time interval between the signboards in the corresponding display content according to the modified playing time interval. Therefore, when the content to be displayed which is sent to the object to be controlled by the server is the display content with the modified playing time interval among the boards in the display content, the board in the display content in the object to be controlled is played and displayed according to the modified playing time interval.
Specifically, finding the display content in a preset database according to the display content identification code comprises:
and inquiring the display content corresponding to the display content identification code in a preset database.
Further specifically, querying the display content corresponding to the display content identification code in a preset database includes:
searching in a preset database through the display content identification code to find the display content corresponding to the display content identification code; if the display content corresponding to the display content identification code is not found, the display content corresponding to the display content identification code is not prestored in the preset database, the display content cannot be controlled, and error information is returned to the control terminal.
In order to monitor the connection of the object to be controlled to ensure that the display content in the object to be controlled can be controlled, timing is carried out after a display content switching instruction is sent to the object to be controlled according to the identification code of the object to be controlled, and whether a data request sent back by the object to be controlled is received within preset time is judged;
if the data request is not received within the preset time, the data connection with the object to be controlled is indicated to have a problem, and an alarm message is sent to prompt the processing as soon as possible so as to ensure that the display content in the object to be controlled can be controlled. And if the data request is received within the preset time, the content to be displayed is sent to the object to be controlled.
The embodiments of the invention are further described herein:
1. when a user has a new display requirement, the background stores the information (equipment name) of the requirement, and then the program generates a unique link (machine code) for the equipment (an object to be controlled), wherein the link can be opened on one equipment at the same time.
2. Under the condition of a network, a method of physical operation such as a peripheral (a mouse and a keyboard) or a script or software control is used, a browser of a large screen (an object to be controlled) opens a unique link (machine code) generated for the large screen in advance, and if the host of the large screen is not provided with the browser, the browser is firstly installed by using the script, and then the link is opened.
3. And after the control end selects the scheme to be updated and confirms, the control end sends the machine code and the scheme ID to be changed to the server. And after receiving the refreshing (updating) message, the server sends a refreshing instruction to the browser.
4. And after the browser receives the instruction, sending a data request to the server, identifying the request by the server, determining that the link of the request source finds the scheme corresponding to the link in the database, and then sending the corresponding display content data to the browser.
5. The browser receives new display content data, and the browser renders the data at the front end to obtain updated display content, so that one updating operation of the display content is completed.
Two specific examples are provided below:
example one
Take the example of hanging a large screen in a hall of a company, suppose that the company will take care of the cooperative company to negotiate the cooperation on one day and then immediately take care of visiting students. The strength and the qualification of the company need to be displayed circularly on a large screen; when receiving the visit of students, the culture, welfare and the like of the company need to be displayed.
1. Preset plan
Two sets of display schemes are preset and stored in the cloud of the company large-screen control account. The first set of display schemes is used for displaying to the cooperation company, and the second set of display schemes is used for the students to see.
2. Opening default presentation scheme
And generating a unique machine code of the large screen, associating the machine code with the first set of display scheme and the second set of display scheme, opening a browser on a host computer for controlling the large screen, inputting the machine code of the large screen, and directly displaying the content of the first set of display scheme on the large screen.
3. Handover scheme
When the persons of the first group of companies leave and the second group of students do not yet come, the large-screen management interface is found in the control end, and the scheme column is switched to the second scheme for confirmation. The large screen is refreshed over a period of 1-2 seconds and the second set of protocols begins to be displayed.
4. Closed display scheme
When the visitors leave, if the visitors return to other schemes or close the large screen, the solution can be switched to other schemes again (the other schemes need to be stored in the display scheme list of the large screen in advance), or the default display content is displayed on the large screen by clicking a close button.

1. A plurality of display schemes to be played are preset and designed, each display scheme comprises a plurality of signboards, and the signboards can contain information such as videos, forms and characters. For example: two display schemes A and B are designed in advance in the system, wherein the scheme A corresponds to two boards: the first billboard is a national weather dynamic map; the second board is a dynamic image of the provincial weather; the order and time of the kanban plays is then set. The scheme B has a billboard which is a traffic condition map of the city.
2. Creating a device name and selecting a presentation scheme to be applied, assuming scheme a is selected, opening the device according to the name in device management, copying a link (machine code) of the device, opening the link on a host of a large screen.
3. Finding the name of the equipment at the control end, controlling a switch for displaying the content on the large screen through the switch in a management interface of the equipment, entering the equipment, selecting other schemes such as scheme B, and displaying the traffic condition map of the city after the large screen is refreshed after the scheme B is determined.
