The setting scenario is: at the opening scene of a concert or a large-scale sports meeting, a sign is placed on each seat, which serves as a display unit for the large screen of the entire seat. The mentioned display unit includes, for example, 9 light points (this application is not limited to this), and each light point includes RGB three-color LEDs. Assuming that there are 30,000 seats on site, the entire seat display screen has a total of 30,000 display units. The sign mentioned includes, for example, a display control card and a display screen connected to the display control card. The signs can be shaken by the audience to interact with the stage, or all signs can be spliced into a large seat display screen for video, animation, text and other media playback. In addition, in order to expand the scope of application, this embodiment uses wireless connection to complete the control of the seat display large screen and program playback, which can not only be applied to some sites where wired connection is not available, but also avoid layout troubles caused by wired connection of each sign ,save costs.

As shown in FIG. 11, it is an architecture diagram of a specific implementation manner of the display control system provided by the first embodiment of this application.

Among them, the host computer can be used to produce program information on the one hand and export the program information to a U disk; on the other hand, it can search and connect multiple display control cards through wireless communication, and perform initial configuration on multiple display control cards. Among them, the host computer sends instructions to multiple display control cards to achieve program playback, switching, and screen switching control functions. The interface of the host computer involved in the embodiments of the present application is simple, simple to operate, and more user-friendly.

For example, a data update card (data update device), a switch, and a router are installed in the flight case. Among them, the data update card can be connected to the U disk to analyze the program information transmitted by the U disk, and then use the switch connected to the data update card to transmit the program content to the display control card in a wired manner for storage; or the router is connected to the data update card, The switch is connected to the router, and the data update card transmits the parsed program information to the display control card through the router and the switch in a wired manner. For example, the flight box can complete the program update of 200 display control cards at a time. This application does not limit the number of flight case update display control cards. The flight case involved in the embodiments of the present application has a large accommodating space, can accommodate multiple display control cards, and has strong performance of the data update card. It is equipped with an Android system and runs more stable.

The display control card stores the program information sent by the data update card. In addition, the display control card can also receive instructions sent by the host computer to control the corresponding indicator to perform program display, switching, pause, and switch screen functions. Among them, the display control card involved in the embodiment of the present application has two communication modes, wireless and wired, and is small in size, quick in response, stable in operation, and large in storage space.

The implementation of the display control system of this embodiment includes, for example, three parts:

1. Program update

When the display control system updates the program, all the display control cards are updated with the same program, that is, the same program will be stored in the memory of the display control card in advance, and then the display control card will be installed on the corresponding seat. Among them, before the display control card is configured, after the display control card is powered on, its corresponding LED light will flash 3 times and then black out, indicating that the display control card can operate normally.

2. Display control card configuration

That is to configure and display the coordinate information of the control card. The host computer retrieves and connects to all display control cards through the wireless RF (Radio Frequency) mechanism and displays all the corresponding sign information, and then the user clicks on one of the sign information on the user interface of the host computer, and the corresponding sign will appear It is lit. At this time, input the physical location information of the current sign in the user interface of the host computer, use the same method until the physical location information of all signs is input, and then use the wireless RF mechanism to combine the physical location information and the assigned display coordinates The information is sent to the corresponding display control card for saving and the configuration of the display control card is completed. After that, synchronize the system time information of all the display control cards, and then start the program playing through the upper computer. At this time, all the display control cards can play the same program synchronously in real time. In this embodiment, all the display control cards are stored with the same program information, which can be placed and installed arbitrarily, and then each display control card can be configured through wireless communication.

3. Command control broadcast control operation

Command control play operations include program play, pause, switch, switch screen and time adjustment, etc.

The following is a detailed description of the above three parts:

【Program update】

The program updates mentioned include manual updates and wireless remote updates. In this embodiment, a manual program update is used as an example. The specific steps for manually updating programs are as follows:

First, the display control card has the function of wired network communication, and the switch, router and data update card are placed in the air box. When updating the program, put the display control card into the flight case. In the flight case, each display control card corresponds to an LED signal light, which is used to indicate whether the corresponding display control card has completed the program update. For example, multiple LED signal lights are connected to the data update card. Produce program information on the host computer, and export the produced program information through U disk. Insert the U disk containing the program information into the data update card of the flight case, so that the data update card reads and parses the program information of the U disk, and distributes it to all the display control cards in the flight case via the router and switch. After the program update of the display control card is successful, the LED signal lights corresponding to each display control card flash.

It should be noted that this application does not limit the platform for producing program information. The program information can be produced on the host computer in the display control system, or produced on other platforms and then imported into the U disk.

In addition, a button can be set on the flight box, and each time the button is pressed, the data update card will start a search and program update. The display control card of the program has been updated at this time, and there is no need to update repeatedly.

It should be noted that the program information mentioned is accompanied by a corresponding program information version number. Each time a version of the program is updated, the program information version number will also change accordingly. After the display control card receives the program information, it will determine whether the received program information version number is consistent with the locally stored program information version number to determine whether to update the program.

It should be noted that there is no need to set a button on the flight case. After inserting the U disk on the flight case, the data update card will automatically start the cyclic update program until all the seat control card programs are updated successfully.

【Display control card configuration】

After the display control card is updated, the program of all display control cards is the same at this time. The customer does not need to care which card needs to be fixed in which position, and there is no need to worry about placing the wrong seat. After placing all the display control cards, The display control card is configured, that is, according to the corresponding coordinate information, when the program is playing, the display control card will only display the program content of the display unit corresponding to the current seat, thereby splicing the program content displayed by multiple signs into a complete picture .

The configuration steps of the display control card are as follows:

The interaction mode between the host computer and the sign is similar to that of the server and the client. Among them, the upper computer is the server, and the sign is the client. The host computer and multiple signs are connected through wireless communication. The networking methods are, for example, Lora (Long Range), WiFi (Wireless Fidelity), 4G (4Generation), and NB-IOT (Narrowband-Internet of Thing). Take the way of Lora module networking as an example for description.

When the sign and the host computer are matched and connected for the first time, the sign on the auditorium can be powered on by area. Of course, when the number of signs on the auditorium is small, all signs on the auditorium can also be powered on uniformly. It should be noted that whether it is to power on the signs in different areas or to power on all signs in a unified manner, just make sure that the upper computer can receive the connection request commands of all signs.

Among them, for the sign that is used for the first time, the sign will undergo a self-check after power-on. For example, the sign will flash 3 times and then black out to indicate that the sign is operating normally. Then the sign will actively send a connection request to the host computer through the Lora module. The content of the connection request message contains sign information, such as the identification code of the display control card such as the SN number and the corresponding initial position coordinate information, and instructions for the first use The initial position coordinate information of the card is, for example, a default value, such as 00-000-000.

When the host computer receives the connection request from multiple signs, it will display the received sign information of the multiple signs in the form of a list, such as the SN number and the initial position coordinate information. Then the user arbitrarily selects one of the sign information on the user interface of the host computer, and the host machine sends a control instruction to the corresponding sign according to the SN number in the selected sign information to control the display state of the corresponding sign, such as the corresponding indication The cards will change from all off to all on. At this time, the installer can input the actual location information as "xx-xxx-xxx" in the user interface of the host computer according to the actual location information (physical location information) of the lighted sign to update the initial position coordinate information of the sign to get the target Location coordinate information. Next, in the same way, the host computer can search for all the signs, and can update the initial position coordinate information of all the signs.

After the initial position coordinate information of all the signs is updated, all the signs are sorted by the obtained multiple target position coordinate information, for example, first sorting according to the area number, and sorting by the coordinate number in each area . After all the signs are sorted according to the coordinate information of the target position, then in the table shown in Figure 9, according to the coordinates of the sign information in the upper left corner as (0,0), from left to right, from top to bottom Assign display coordinates to each sign information, and after all sign information is assigned display coordinates, the target position coordinate information and display coordinates are respectively solidified into each control card. Specifically, the host computer sends the corresponding display coordinates and target position coordinate information to the corresponding sign according to the SN number. In this way, it can be guaranteed that each sign can receive the corresponding display coordinates and target position coordinate information. Then, according to the existing mature control methods, you can control the various signs scattered in the large seat display screen to play text, pictures and videos.

In addition, it should be noted that after the first configuration of multiple signs is completed, when the signs are powered on for the second time, the control cards corresponding to the multiple signs will actively send their own SN number and position coordinate information to Host computer. The upper computer sorts according to the position coordinate information to complete the virtual splicing of the entire seat display screen.

Among them, the same program content is sent to each sign, and then each sign will intercept the part that needs to be displayed in the program content according to its corresponding display coordinates for display control, which is the same as the display control of the existing mature receiving card The principle is the same, so I won't repeat it here.

【Command control broadcast control operation】

①Program switching: The host computer searches for the program information of any display control card through the Lora module, and sends the program switching command through the specified protocol to switch the content of the display control card. Since all the display control cards have the same program information, only search is required Any one display control card is sufficient, and all display control cards under the Lora module can receive the command to respond and switch the playback content.

②Random point search: The host computer starts the random point search function to interact with the audience. When the user clicks to pause, the host computer randomly lights up a sign in response to the user's operation, while the signs corresponding to other seats are in a black screen state.

③Switch screen: The host computer sends a switch screen instruction to the display control card through the Lora module, and the corresponding display control card responds to the instruction after receiving the switch screen instruction, and completes the control of the corresponding sign to turn on or off. It needs to be explained. The closing of the indicated sign is just a black screen operation of the sign, not an operation of disconnecting the power supply.

In summary, the display control system proposed in the first embodiment of the present application uses the solution of wirelessly connecting the signs to the host computer to complete the control of multiple signs and program playback, which expands the application range of the display control system and makes the operation more convenient It avoids the layout trouble caused by the wired connection of the sign, avoids the presence of many wires in the auditorium, which is inconvenient for the audience to move around, reduces the impact of the wire on the audience, saves costs, and realizes the live stage and auditorium The real-time interaction enhances the effect of the performance.
