Those of ordinary skill in the art can understand the specific meanings of the above terms in this application in specific situations. In addition, in the description of the present application, unless otherwise specified, "plurality" means two or more. "And/or" describes the association relationship of associated objects, indicating that there may be three types of relationships, for example, A and/or B may indicate: A exists alone, A and B exist simultaneously, and B exists independently. The character "/" generally indicates that the contextual objects are an "or" relationship.

With the development of science and technology, light-emitting diodes have emerged as the times require. Light-emitting diodes are a commonly used light-emitting device that can efficiently convert electrical energy into light energy. Light-emitting diodes can be used in the field of screen control. For example, LED lights can be used to form an LED display to display various information such as text, images, and videos. When displaying information on the LED display, multiple sending cards can be used to control the LED display. Each of the sending cards can control a part of the display area of the LED display, so as to realize the control of the entire LED display. For example, when the external application side controls the LED display, it can be controlled by cascading sending cards. The sending card cascading includes but not limited to serial port cascading, network cascading, network and serial port combined cascading and so on.

Optionally, FIG. 1 shows a schematic background diagram of a method for controlling a screen area according to an embodiment of the present application. As shown in Figure 1, multiple sending cards are cascaded through the network. The router is respectively connected to the terminal and the network port of each sending card. When the LED display is used without a router, the connection between the terminal and the sending card is very complicated, and the network address of the sending card needs to be set to a fixed network address in advance, and only one sending card can be used at the same time, and the terminal needs to be set to the same Only the network address of the network segment can carry out information transmission, so the screen control steps are complicated, which makes the screen area control less convenient.

Optionally, FIG. 2 shows a schematic background diagram of a method for controlling a screen area according to an embodiment of the present application. As shown in Figure 2, multiple sending cards are cascaded through the network and serial port, that is, sending card 1 and sending card 2 are connected to the router, sending card 3 is connected to sending card 1 through the serial port, and sending card 4 is connected to sending card 2 through the serial port , that is, the input serial port of sending 3 is connected to the output serial port of sending card 1, and the input serial port of sending 4 is connected to the output serial port of sending card 2. When performing information transmission, it is necessary to separately set network addresses for sending card 1 and sending card 2, and the number of information transmission steps is limited. That is, all sending cards need to be transferred when communicating between the underlying sending card and the terminal. For example, when using 115200 baud rate for information transmission, it takes 71ms to transmit 1K data to the first sending card, and 71*ms to transmit to the nth card, where n is a positive integer. Therefore, in the scenario shown in FIG. 2 , the transmission speed of the serial port is relatively slow, and the screen control steps are complicated, which makes the screen area control less convenient.

The first sending card does not specifically refer to a certain fixed sending card. Sending card refers to the integrated board used to process and distribute information. A sending card can usually control at least one screen area.

It is easy to understand that the first sending card includes a routing module, a first routing network port and a first sending card network port. The routing network port refers to the network port connected to the routing module, and the first routing network port refers to the network port used to connect the routing module and the first sending card. The network port of the sending card refers to the network port set by the sending card itself, and the network port of the sending card is not directly connected to the routing module. The network port of the first sending card refers to the network port set on the first sending card itself. The network port of the first sending card does not refer to a fixed network port. When the first sending card changes, the network port of the first sending card will change accordingly.

According to some embodiments, the first sending card includes a routing module, and when controlling the screen area corresponding to the first sending card, based on the routing module, the first sending card can acquire transmission information. When the first sending card obtains the transmission information based on the routing module, the first sending card may obtain the information type of the transmission information. The information type refers to the attribute of the information transmission direction of the transmission information, and the information type does not specifically refer to a certain fixed information type. For example, when the transmission information changes, the information type corresponding to the transmission information will also change accordingly.

S102. If the information type indicates that the transmission information is return information, transmit the return information to the terminal through the first routing network port and the first sending card network port;

According to some embodiments, the returned information refers to information obtained by the first sending card and to be transmitted to the terminal. The return information obtained by the first sending card may be generated directly based on the user's return instruction, and may also be the return information transmitted to the first sending card by the second sending card.

It is easy to understand that, based on the routing module, the first sending card can obtain the transmission information. When the first sending card acquires the transmission information, the first sending card may acquire the information type of the transmission information. If the information type indicates that the transmission information is return information, the first sending card may transmit the return information to the terminal through the first routing network port and the first sending card network port.

S103. If the information type indicates that the transmission information is area control information, based on the area control information, control the screen area corresponding to the first sending card to perform a display operation.

According to some embodiments, the area control information refers to information acquired by the first sending card and instructing the first sending card to perform a display operation on the screen area corresponding to the first sending card. The area control information is acquired by the first sending card from the terminal through the network port of the first sending card.

It is easy to understand that, based on the routing module, the first sending card can obtain the transmission information. When the first sending card acquires the transmission information, the first sending card may acquire the information type of the transmission information. If the information type indicates that the transmission information is area control information, then based on the area control information, the first sending card may control a screen area corresponding to the first sending card to perform a display operation.

Optionally, FIG. 4 shows an exemplary schematic diagram of a display screen in the embodiment of the present application. As shown in FIG. 4 , for example, the screen areas corresponding to the first sending card are area 1 and area 4 . When the area control information acquired by the first sending card is to display the meeting time in area 1 and the conference subject in area 4 . When the first sending card acquires the area control information, the first sending card can display the meeting time in area 1 and the meeting theme in area 4 .

Please refer to FIG. 5 , which shows a schematic flowchart of a method for controlling a screen area provided by an embodiment of the present application. specific:

S201. Obtain sorting information of the first sending card;

According to some embodiments, the technical solutions of the embodiments of the present application can be used for the control of LED display screens, or other scenarios where sending card cascade control is used. The technical solutions of the embodiments of the present application can be used in scenes where the screen resolution of the LED display screen is relatively large, and the screen resolution refers to the number of pixels in the vertical and horizontal directions. For example, the technical solution of the embodiment of the present application may be used in a scene with a screen resolution of 1600*1200.

It is easy to understand that the technical solution of the embodiment of the present application is applied to the first sending card in the sending card set, that is, the execution subject of the embodiment of the present application is the first sending card in the sending card set. The first sending card is any sending card in the sending card set, that is, the first sending card does not specifically refer to a certain fixed sending card. A collection is a collection of concrete or abstract objects with certain properties. The sending card set refers to the set formed by at least one sending card.

According to some embodiments, the sending card set includes at least one first sending card. Before the first sending card obtains the transmission information based on the routing module, the first sending card may obtain the sorting information of the first sending card. The sorting information is used to indicate the sorting of the first sending card in the sending card set. Since different sending cards have different execution steps when receiving the area control information or returning the information, obtaining the sorting information of the first sending card can improve the accuracy of screen area control and the convenience of screen control.

Optionally, the ordering of at least one first sending card in the sending card set may be determined based on the distance between the first sending card and the terminal, that is, the one closest to the terminal is the first sending card, and the farthest connected to the terminal is the last sending card. The first sending card and the terminal can be directly connected, or connected through an external router. For example, in the background diagram shown in FIG. 2 , the sorting information of sending card 1 is first, and the sorting information of sending card 3 is second.

It is easy to understand that sorting information does not specifically refer to certain fixed information. The sorting information is determined by the number of first sending cards included in the sending card set. When the number of the first sending card in the sending card set changes, the sorting information of the first sending card will also change accordingly.

According to some embodiments, before the first sending card controls the screen area corresponding to the first sending card to perform a display operation, the first sending card may acquire the sorting information of the first sending card. The sorting information obtained by the first sending card may be, for example, the sending card ranked first, or the sending card ranked last.

S202, if the sorting information indicates that the first sending card is any sending card before the last sending card in the sending card set, then control the routing module to configure the first network address to the first routing network port, and then configure the first network address through the second routing network port Configure the second network address to the second sending card network port of the second sending card;

According to some embodiments, the second sending card is the next sending card adjacent to the first sending card in the sending card set, that is, the second sending card refers to the sending card in the sending card set that is adjacent to the first sending card and is far away from the terminal next sending card. The second sending card does not specifically refer to a certain fixed sending card. For example, when the first sending card changes, the second sending card will also change accordingly. The network port of the second sending card is a network port provided on the second sending card itself, and the network port of the second sending card is not directly connected to the routing module of the second sending card.

It is easy to understand that the second sending card is the next sending card adjacent to the first sending card in the sending card set, and the second routing network port of the first sending card is connected to the network port of the second sending card. Therefore, after the first sending card in the sending card set is determined, the sending card corresponding to the second sending card network port connected to the second routing network port of the first sending card may be determined as the second sending card.

Optionally, the network address (Network address) refers to the logical address of the network port, where one network port corresponds to one network address. The network address of a network port does not specifically refer to a fixed network address. The network address may be modified based on the received network address modification instruction. The first network address refers to the address of the network port configured by the first sending card to control the routing module to the first routing network port. The second network address refers to when the first sending card is any sending card before the last sending card in the sending card set, the first sending card controls the routing module to the second sending card of the second sending card through the second routing network port. The address configured by the network port of the sending card. Since the first sending card can obtain the address modification instruction, the first network address and the second network address do not specifically refer to a certain fixed address.

According to some embodiments, when the first sending card acquires the sorting information of the first sending card, the first sending card may determine whether the sorting information indicates that the first sending card is the last sending card in the sending card set. When the first sending card determines that the sorting information indicates that the first sending card is any sending card before the last sending card in the sending card set, that is, the sorting information indicates that the first sending card is not the last sending card in the sending card set , the first sending card can control the routing module to configure the first network address to the first routing network port, and configure the second network address to the second sending card network port of the second sending card through the second routing network port. Wherein, the second routing network port of the first sending card is not configured with a network address.

It is easy to understand that the sending cards whose information is sorted from the first to the last in the sending card set may be, for example, a Q sending card, a W sending card, an E sending card, an R sending card, and a T sending card. The first sending card may be, for example, a W sending card, and the second sending card may be, for example, an E sending card. W sending card includes w routing module, first routing network port w1 routing network port, second routing network port w2 routing network port, first sending card network port w3 sending card network port, E sending card includes second sending card network port The e3 sending card network port is connected to the w2 routing network port. When the first sending card W sending card determines that the W sending card is the second sending card based on the obtained sorting information, the W sending card can control the w routing module to configure the first network address for the w1 routing network port. The first network address may be, for example, an Internet Protocol (Internet Protocol, IP) address, and the first network address may be, for example, 123.12.123.12. The W sending card configures the second network address to the second sending card network port e3 of the sending card network port of the second sending card E via the second routing network port w2. The second network address may be, for example, an IP address, and the second network address may be, for example, 123.12.123.13.

S203, acquire the transmission information based on the routing module, and acquire the information type of the transmission information;

The specific process is as described above, and will not be repeated here.

According to some embodiments, when the first sending card obtains the transmission information based on the routing module, the first sending card may obtain the information type of the transmission information based on the network port for obtaining the transmission information. For example, when the routing module obtains the transmission information through the second routing network port of the first sending card, the routing module and the first routing network port, the first sending card may determine that the information type of the transmission information is the return information type. When the routing module obtains the transmission information through the network port of the first sending card, the first sending card may determine that the information type of the transmission information is the area control information type.

Specifically, the first sending card obtains the transmission information based on the routing module. If the sorting information obtained by the first sending card indicates that the first sending card is any sending card before the last sending card in the sending card set, that is, sorting The information indicates that the first sending card is not the last sending card in the sending card set, and the routing module is controlled to configure the first network address to the first routing network port, and send the second network address to the second sending card through the second routing network port. After the network port of the sending card is configured with the second network address, the first sending card can obtain the transmission information.

S204. If the information type indicates that the transmission information is return information, obtain the return information through the first routing network port;

According to some embodiments, when the sorting information indicates that the first sending card is any sending card before the last sending card in the sending card set, that is, the sorting information indicates that the first sending card is not the last sending card in the sending card set , the first sending card can obtain the return information through the first routing network port. The return information is the information transmitted by the second sending card to the routing module through the network port of the second sending card and the second routing network port of the first sending card.

It is easy to understand that when the first sending card acquires the transmission information, the first sending card can acquire the information type of the transmission information. If the information type indicates that the transmission information is return information, the first sending card may obtain the return information through the first routing network port. Specifically, the first sending card may acquire the returned information based on the first network address. For example, the W sending card may acquire the return information based on the first network address 123.12.123.12.

S205, transmit the returned information to the terminal through the network port of the first sending card;

According to some embodiments, when the first sending card acquires the transmission information, the first sending card may acquire the information type of the first transmission information. If the information type indicates that the transmission information is return information, the first sending card obtains the return information through the first routing network port. When the first sending card obtains the returned information through the first routing network port, the first sending card may transmit the returned information to the terminal through the first sending card network port.

It is easy to understand that FIG. 6 shows an exemplary schematic diagram of a return information transmission method according to an embodiment of the present application. For example, when the routing module of the W sending card obtains the return information transmitted by the E sending card through the second routing network port w2 of the W sending card and the e3 sending card network port of the E sending card, the W sending card can pass the first The routing network port w1 obtains the returned information from the routing module. When the W sending card obtains the returned information, the W sending card may transmit the returned information to the terminal through the first sending card network port w3 sending card network port.

Optionally, the first sending card may also directly obtain the returned information, that is, the returned information is generated by the first sending card, not transmitted by the second sending card. When the first sending card generates the return information, the first sending card may transmit the generated return information to the terminal through the network port of the first sending card. For example, when the W sending card receives the return instruction from the user, the W sending card can generate the return information. When the W sending card obtains the returned information, the W sending card may transmit the returned information to the terminal through the first sending card network port w3 sending card network port.

S206, if the sorting information indicates that the first sending card is any sending card before the last sending card in the sending card set, and the information type indicates that the transmission information is area control information, then transmit the area control information through the first routing network port, The routing module, the second routing network port and the second sending card network port are transmitted to the second sending card;

According to some embodiments, when the sorting information indicates any sending card before the last sending card in the sending card set of the first sending card, the first sending card may acquire the information type of the transmission information. The area control information is obtained by the first sending card through the network port of the first sending card. If the first sending card determines that the information type of the transmission information indicates that the transmission information is regional control information, then the first sending card can send the regional control information through the first routing network port, the routing module, the second routing network port and the second sending card. The network port transmits to the second sending card.

It is easy to understand that FIG. 7 shows an exemplary schematic diagram of a method for transmitting area control information according to an embodiment of the present application. For example, when the W sending card obtains the area control information transmitted by the Q sending card through the second routing network port q2 routing network port of the Q sending card and the w3 sending card network port, the W sending card can pass the area information through the first routing network port The w1 routing network port transmits to the w routing module. The W sending card can control the w routing module to transmit the area control information to the second sending card E sending card through the second routing network port w2 routing network port. Specifically, the W sending card can control the w routing module to transmit the area control information to the second sending card E sending card through the second routing network port w2 routing network port and the e3 sending card network port of the second sending card E sending card .

S207. Based on the area control information, control the screen area corresponding to the first sending card to perform a display operation.
