For example, the flight box can complete the program update of 200 display control cards at a time. The number of the display control cards updated by the flight boxes is not limited in the application. The accommodation space of aviation case that this application embodiment relates to is big, can hold many display control cards, and the data update card's performance is strong, and it carries on tall and erect system, and the operation is more stable.

The display control card stores program information sent by the data updating card, and can also receive instructions sent by the upper computer to control the corresponding indicator to perform functions of program display, switching, pause, screen opening and closing and the like. The display control card related to the embodiment of the application has two communication modes of wireless and wired, and is small in size, fast in response, stable in operation and large in storage space.

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

1. program update

When the display control system updates programs, the same programs are updated for all the display control cards, namely the same programs are stored in the memory of the display control cards in advance, and then the display control cards are installed on corresponding seats. Before the display control card is not configured, the corresponding LED lamp point of the display control card flickers for 3 times and then is blackened after the display control card is powered on, so that the display control card can normally run.

2. Display control card configuration

I.e. the coordinate information of the configuration display control card. The upper computer is connected to all display control cards through wireless RF (Radio Frequency) mechanism retrieval and displays all corresponding sign information, then a user clicks one of the sign information on a user interface of the upper computer, the corresponding sign can be lighted, at the moment, the physical position information of the current sign is input on the user interface of the upper computer, the same method is used until the physical position information of all signs is input, and then the physical position information and the endowed display coordinate information are sent to the corresponding display control card through the wireless RF mechanism to be stored, namely the configuration of the display control card is completed. And then, synchronizing the system time information of all the display control cards, and starting the program playing through the upper computer, wherein all the display control cards can synchronously play the same program in real time. In this embodiment, all the display control cards store the same program information, so that arbitrary placement and installation can be realized, and then each display control card is configured in a wireless communication manner.

3. Command controlled broadcast control operations

The command control playing operation comprises program playing, pausing, switching, screen switching, time correction and the like.

The following specific schemes are described for the above three parts:

[ PROGRAM UPDATE ]

The mentioned program updates include manual updates and wireless remote updates. The present embodiment is illustrated in a manner of manually updating a program. The specific steps of manually updating the program are as follows:

firstly, the display control card has the function of wired network communication, and a switch, a router and a data updating card are placed in an aircraft box. And when the program is updated, the display control card is placed into the flight box. In the aviation case, each display control card corresponds to one LED signal lamp and is used for indicating whether the corresponding display control card finishes program updating. For example, a plurality of LED signal lamps are connected to the data update card. And (4) making program information on the upper computer, and exporting the made program information through a U disk. The USB flash disk with the stored program information is inserted into a data updating card of the aviation case, so that the data updating card reads and analyzes the program information of the USB flash disk, the program information is distributed to all display control cards in the aviation case through the router and the exchanger, and when the programs of the display control cards are updated successfully, LED signal lamps corresponding to all the display control cards flicker.

It should be noted that the present application is not limited to the platform for creating the program information, and the program information may be created by an upper computer in the display control system, or may be created on another platform and then imported into the usb disk.

In addition, a key can be arranged on the aviation case, and the data updating card starts searching and program updating once when the key is pressed once. The display control card of the program has been updated at this time, and repeated updating is not required.

It should be noted that, the mentioned program information is accompanied by a corresponding program information version number, and each time a program is updated, the program information version number is also changed accordingly. After the display control card receives the program information, whether the version number of the received program information is consistent with the version number of the locally stored program information is judged so as to determine whether to update the program.

It should be noted that, no button may be provided on the aviation case, and after the usb disk is inserted into the aviation case, the data update card automatically starts to update programs cyclically until all the programs of the seat control card are updated successfully.

[ display control card configuration ]

After the display control cards finish updating programs, at the moment, the programs of all the display control cards are the same, a client does not need to care which card needs to be fixedly placed at which position, and does not need to worry about seat misplacing.

The display control card configuration steps are as follows:

and an interactive mode similar to that of a server and a client is adopted between the upper computer and the sign. The upper computer is a server, and the indication board is a client. The upper computer and the plurality of signs are connected by a wireless communication mode, the networking mode is, for example, Lora (long range), wifi (wireless fidelity), 4G (4Generation) and NB-IOT (narrow-Internet of things), and the mode of networking by the Lora module is described as an example below.

When sign and host computer carry out first accordant connection, can carry out the subregion according to the region to the sign on the auditorium and go up the electricity. Of course, when the number of the signs on the auditorium is not large, all the signs on the auditorium can be uniformly electrified. It should be noted that, no matter the signs are powered on in different areas or all signs are powered on uniformly, the upper computer can receive the connection request commands of all signs.

Wherein, to the sign of using for the first time, the sign can carry out the self-checking after the electricity, for example the sign can flash 3 times back and black fall to show that this sign operation is normal. Then the sign will actively send a connection request to the upper computer through the Lora module, the content of the connection request message includes sign information, for example, including an identification code of the display control card, such as an SN number, and corresponding initial position coordinate information, for example, the initial position coordinate information of the sign for the first use is a default value, such as 00-000-.

After the upper computer receives the connection requests sent by the plurality of signs, the received sign information of the plurality of signs, such as SN (serial number) and initial position coordinate information, can be displayed in a list form. Then the user selects one of the sign information on the user interface of the upper computer at will, and then the upper computer 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, for example, the corresponding sign will be changed from full-off to full-on. At the moment, an installer can input actual position information as 'xx-xxx-xxx' on a user interface of the upper computer according to the actual position information (physical position information) of the lighted sign so as to update the initial position coordinate information of the sign to obtain target position coordinate information. Next, in the same manner, the upper computer may search for all signs, and may update the initial position coordinate information of all signs.
