As shown in fig. 8, the program updating system 10 includes, for example, a media server, a control system, and an LED display screen body, and optionally includes a main control server, a Lora base station, and a Lora module, and a status monitoring server. Fig. 8 only illustrates one LED display screen as an example to illustrate the connection relationship between the LED display screen and other servers, and in an actual application scenario, a plurality of LED display screens, for example, hundreds of LED display screens, may be involved.

The control system and the Lora module form the control card, the control card and the LED display screen form the LED display screen, and the Lora module can be externally connected with an ARM processor in the control system, namely, the Lora module and the control system are of a split structure; or the Lora module and the control system are arranged on the same circuit board, namely, the Lora module and the control system are of an integral structure.

The playing of the plurality of LED display screens forms a complete picture, and is realized by solidifying the display content in advance in the control card and synchronously playing. The program material is produced in advance as follows:

firstly, making an integral material, namely a material required by a plurality of display screens to display a complete picture, and then cutting the complete picture material according to the number of the display screen bodies, for example: the size of the LED display screen is 96 × 96, the complete picture material is cut according to 96 × 96 pixels corresponding to each LED display screen body to obtain a plurality of materials, namely media, corresponding to the LED display screens respectively, then each media is named according to the format of an address code _ video playing serial number, for example, 0201_01.mov, the former number represents the address code of the LED display screen corresponding to the media, the address code represents a row-column two-dimensional coordinate or a one-dimensional information code, and the next 2-digit number represents the media playing serial number. Then, as shown in fig. 9, a media folder is created according to the address code of each LED display screen, for example, 2 rows and 1 columns are 0201, for example, address codes of 9999 LED display screen bodies are supported, and the media corresponding to each LED display screen is placed in the corresponding media folder. A plurality of media folders corresponding to the plurality of LED display screens are stored in a media server and/or a U disk, for example. Each media folder includes, for example, media and md5.json files, each media folder does not limit the number of media, and the md5.json files store media information corresponding to the media, including media name, media size, and media feature code, i.e., MD5 code, where MD5 code is a unique identifier of the media, which can prevent repeated downloading of the media. The size of each medium is the same as the resolution of the corresponding display screen, so that the waste of flow can be prevented, and the medium size can also realize the function of continuous transmission after power failure.

When the LED display screen needs to update programs, the control card can realize various program updating modes.

The first program updating mode is cable network updating, i.e. the ARM processor in the control system is connected to the RJ45 network port, and the RJ45 network port is connected to the media server through the network cable. When an ARM processor in the control system is connected to a network through a wired network cable, media in corresponding media folders can be automatically downloaded from a media server according to local address codes, because naming rules of the media folders are well agreed in advance, as described above, media in the media folders corresponding to the local address codes of the control card can be downloaded by control cards of different LED display screens, and after a program is updated, an indicator lamp arranged on the control card flickers, and the LED display screens can directly play the first media to indicate that the program is updated successfully.

The second program updating mode is 4G network wireless updating, namely, an ARM processor in the control system is connected with a 4G network module, and the 4G network module is connected to a media server through a 4G base station. For example, the Unicom is connected to a 4G base station dedicated to the rehearsal site layout, the Unicom company provides a 4G module of a mini PCIE interface, the 4G module is connected to an ARM processor, and the 4G base station can be connected to the 4G base station when the 4G base station exists. When the ARM processor in the control system is accessed to the 4G network, media in the corresponding media folder can be automatically downloaded from the media server according to the local address codes, after the program is updated, the indicator lamp arranged on the control card flickers, and the LED display screen can directly play the first media to indicate that the program is updated successfully.

Before updating programs, the LED display screen needs to be connected to a media server, and the media server allocates an IP address of a public network through an operator network or forms a special network with a control system through a special network. The control system needs to connect to the media server by configuring the APN information. The configuration of APN information is implemented, for example, as follows: configuring each display screen through a USB flash disk; or if the control system is connected to the state monitoring server by default, the connected LED display screens can be configured in batches through the state monitoring server.

The media folder is stored, for example, under a directory of a download service of the media server. When a control system receives a program updating instruction transmitted by a main control server through a Lora base station and a Lora module or a program updating command directly issued from a state monitoring server, the control system of the display screen downloads media corresponding to the control system according to local address codes, wherein the control system is connected to a media server through a file downloading protocol such as http or ftp, repeated downloading can be prevented through md5 codes in MD5.json files in a media folder, and breakpoint continuous transmission can be supported through media size information. And after the control system finishes downloading the media, an updating finishing instruction is sent to the state monitoring server, so that the state monitoring server can conveniently update the state.

Hundreds to thousands of LED display screens may be involved in a performance site, a state monitoring server is arranged for conveniently monitoring the downloading progress of each LED display screen and controlling the downloading process, and a control card is connected with the state monitoring server through an MQTT/TCP protocol, wherein the MQTT protocol can realize two-way communication, and the server is very small in resource consumption in the process of establishing a link, so that the system is very suitable for the application of the Internet of things. The state monitoring server can be realized through a BS framework or a CS framework, when the configuration parameters of the control system are correct, the state monitoring server is automatically connected, then the SN number and the address code of the state monitoring server are uploaded, the state monitoring server establishes a state monitoring list after receiving the information, monitors the information such as the on-line condition, the downloading completion condition and the playing sequence number of the current playing media of the LED display screen, and can also control the on-off screen, adjust the brightness and the like in batch through the state monitoring server. The status monitoring server may send program update commands to the LED display screens in bulk for media download from the media server.

In addition, the program can be updated through the USB flash disk, namely, the ARM processor in the control system is connected with the USB interface, and the USB interface is connected to the USB flash disk. All media folders are stored in the U disk, when the ARM processor detects that the U disk is inserted, the U disk can be automatically downloaded to download media in the corresponding media folders according to local address codes, when a program is updated, an indicator lamp arranged on the control card flashes, and the LED display screen can directly play the first media to indicate that the program is updated successfully.

In summary, the program updating system provided in the embodiment of the present invention determines the target folder through the local address code, acquires the information recording file from the target folder, and matches the information recording file with the local information recording file to determine the media to be downloaded, thereby completing the program updating, avoiding the situation of repeatedly downloading the same program content when the program is updated on the display screen, and increasing the program updating speed of the display screen; the media folder name comprises the address code of the corresponding display screen, so that the media folder name can be quickly matched with the target folder, and the condition that media corresponding to other display screens are obtained is avoided; setting a media feature code as a unique identification code of each media in the information recording file, so as to determine the media to be downloaded for updating programs; the updating completion instruction is sent to the state monitoring server, so that the downloading progress of each display screen can be conveniently monitored, and the user experience is improved; the resolution ratios of the corresponding display screens of all media in the media folder are the same, so that the waste of flow is prevented, the transmission flow is reduced, and various defects of intercepting the spliced images spliced and displayed by the plurality of display screens after being sent to the display screens are avoided.

[ second embodiment ]

Referring to fig. 10, a second embodiment of the present invention provides a program updating method. As shown in fig. 10, the program updating method includes, for example, steps S11 to S14.

Step S11: determining a target folder from a plurality of media folders according to a local address code, wherein the plurality of media folders correspond to a plurality of display screens one to one, and each media folder comprises at least one media;

step S12: acquiring an information recording file in the target folder;

step S13: matching the information recording file with a local information recording file to determine a medium to be downloaded in the at least one medium; and

step S14: and downloading the media to be downloaded from the target folder to update the program.

Specifically, the local address code mentioned in step S11 is, for example, a position code, i.e., a row-column two-dimensional coordinate, of the display screen in a complete picture displayed by splicing a plurality of display screens, or a serial number, i.e., a one-dimensional information code, of the display screen in the plurality of display screens. A plurality of media folders are provided and stored in a media server, for example, and the display screen can be in communication connection with the media server through a wired network or in communication connection with the media server through a mobile network; or a plurality of mentioned media folders are stored in a mobile storage device such as a USB flash disk, and the display screen is provided with a USB interface connected with the USB flash disk, so that the program updating under the condition of no network is realized. The mentioned multiple display screens are, for example, multiple LED display screens, including an LED display screen body and a control card. The display screens are handheld screens, so that a user can hold the display screens to move, and the display screens are used as display screens of the performance props in performance occasions. The name of the media folder to which the mentioned media folder corresponds includes, for example, an address code of the corresponding display screen. The mentioned media are for example videos or pictures etc. The names of the media in the same media folder include, for example, the address code and the media playing sequence number of the corresponding display screen. The size of each media in the media folder is the same as the resolution of the corresponding display screen, so that the situation that the display screen still needs to perform intercepting operation after receiving the media is avoided, traffic waste is avoided, and transmission traffic is reduced.

Further, step S11 includes, for example: and matching the local address codes with the address codes in the names of the media folders, and taking the successfully matched media folder as the target folder.

The information recording file referred to in step S12 is a file in which media information corresponding to at least one media included in the media folder is recorded. The media information includes, for example, a media name, a media size, and a media feature code, wherein the media feature code is an automatically generated unique identifier of the media and is not tampered with. Wherein the media size of each media in the media folder is, for example, the same as the corresponding display resolution.

The local information recording file referred to in step S13 is a file in which local media information is recorded, and includes the name, size, and feature code of the local media.

Further, step S13 includes, for example: and matching the media feature code corresponding to each media in the information recording file with the local media feature code corresponding to each local media in the local information recording file, and taking the media with unsuccessful matching as the media to be downloaded. It can be understood that, when the matching between the media feature code and the local media feature code is successful, that is, the two media are the same media, the downloading is not performed, and only the media with unsuccessful matching are used as the media to be downloaded.

Further, step S14 includes, for example: and downloading the media to be downloaded from the target folder, and sending an updating completion instruction after the downloading of the media to be downloaded is completed. The updating completion instruction is sent to a state monitoring server, for example, so that the state monitoring server updates the monitoring state according to the updating completion instruction. The mentioned state monitoring server is, for example, a server for monitoring the operating states of a plurality of display screens, and communicates with the display screens through, for example, MQTT or TCP protocol. The updating completion instruction is sent to the state monitoring server after the program is updated, so that the state monitoring server completes monitoring state updating, the running states of the display screens can be monitored in real time, and the use experience of a user is improved.

Further, step S14 includes, for example: recording the progress of downloading the media to be downloaded in real time to obtain the downloading completion size of the media to be downloaded; when the power is cut off and the download is restarted, responding to the fact that the download completion size of the media to be downloaded is smaller than the media size of the media to be downloaded, and continuing to download the media to be downloaded based on the download completion size of the media to be downloaded.

Further, after step S14, the program updating method provided in this embodiment further includes: generating a target media feature code according to the downloaded media to be downloaded; matching the target media feature code with the media feature code corresponding to the media to be downloaded in the information recording file; and in response to the target media feature code being the same as the media feature code corresponding to the media to be downloaded in the information recording file, completing the program updating.

It should be noted that the program updating method provided in this embodiment is implemented in the program updating system provided in the first embodiment, and for the sake of brevity, detailed steps related to the program updating method may refer to the relevant description of the first embodiment, and are not described herein again.

In summary, the program updating method provided in the embodiment of the present invention determines the target folder through the local address code, acquires the information recording file from the target folder, and matches the information recording file with the local information recording file to determine the media to be downloaded, thereby completing the program updating, avoiding the situation of repeatedly downloading the same program content when the program is updated on the display screen, and increasing the program updating speed of the display screen; the media folder name comprises the address code of the corresponding display screen, so that the media folder name can be quickly matched with the target folder, and the condition that media corresponding to other display screens are obtained is avoided; setting a media feature code as a unique identification code of each media in the information recording file, so as to determine the media to be downloaded for updating programs; the updating completion instruction is sent to the state monitoring server, so that the downloading progress of each display screen can be conveniently monitored, and the user experience is improved; the resolution ratios of the corresponding display screens of all media in the media folder are the same, so that the waste of flow is prevented, the transmission flow is reduced, and various defects of intercepting the spliced images spliced and displayed by the plurality of display screens after being sent to the display screens are avoided.
