Example one
Fig. 1 is a schematic structural diagram of a display screen control system according to an embodiment of the present invention, which is applicable to a case where a display screen using multiple receiving cards in cascade connection is controlled. As shown in fig. 1, the display screen control system includes: a transmitting card 100 and a plurality of cascade-connected receiving cards (fig. 1 shows an example including 6 receiving cards, which are a first receiving card (i.e., a head-end receiving card) 201, a second receiving card 202, a third receiving card 203, a fourth receiving card 204, a fifth receiving card 205, and a sixth receiving card (i.e., a tail-end receiving card) 206 in sequence in a cascade order); the sending card 100 includes a first network port 111 and a second network port 112, where the first network port 111 is used to push display data to the first-end receiving card 201 in the cascade connection, and the second network port 112 is used to receive the display data returned by the tail-end receiving card 206 after being transmitted by each of the cascade-connected receiving cards.
Specifically, the number of the receiving cards connected in cascade is not limited to the above 6, and may be any number greater than 1. After the sending card 100 generates the display data, the display data may be pushed to the head-end receiving card 201 through the first internet access 111, and then the head-end receiving card 201 may transmit the received display data to the second receiving card 202 (if the number of the receiving cards is 2, the head-end receiving card 201 may directly transmit the display data to the tail-end receiving card 206), so that the display data may be sequentially transmitted to the tail-end receiving card 206 through each receiving card according to the sequence of the cascade connection, and then the tail-end receiving card 206 transmits the received display data back to the second internet access 112 of the sending card 100, where the generation manner of the display data in the sending card 100 is not limited. The receiving cards can be connected through the internet access, when the network connection between the receiving cards is good, the returned display data can be received through the second internet access 112 after the display data is pushed through the first internet access 111, and when a network fault exists between the receiving cards, the returned display data cannot be received through the second internet access 112 after the display data is pushed through the first internet access 111. So that it can be determined whether the network connection between the receiving cards is normal according to whether the second portal 112 can receive the display data.
Optionally, as shown in fig. 2, the receiving card includes a third internet access and a fourth internet access (as the head-end receiving card 201 in fig. 2 includes a third internet access 211 and a fourth internet access 212), the third internet access is used to receive the display data pushed by the first internet access 111 or sent by a previous receiving card, and the fourth internet access is used to send the display data to a next receiving card or send the display data back to the second internet access 112. Specifically, each receiving card can receive the display data through the corresponding third port and send the display data out through the corresponding fourth port, so that the process of outputting the display data from the first port 111 through network cable connection, transmitting the display data through each receiving card in cascade connection, and then transmitting the display data back to the second port 112 is realized. The third port 211 of the first-end receiving card 201 is configured to receive the display data pushed by the first port 111, the third ports of the other receiving cards are configured to receive the display data sent by the previous receiving card, the fourth port of the tail-end receiving card 206 is configured to return the display data to the second port 112, and the fourth ports of the other receiving cards are configured to send the display data to the next receiving card.
On the basis of the above technical solution, optionally, as shown in fig. 2, the transmitting card 100 further includes an ARM module 120, configured to generate the display data, specifically, the display data may be generated through the ARM module 120 according to an actual application requirement, and a generation manner of the display data may also not be limited.
On the basis of the above technical solution, optionally, as shown in fig. 2, the transmitting card 100 further includes an FPGA module 130, configured to receive the display data transmitted by the ARM module 120, and push the display data to the head end receiving card 201 through the first internet access 111. Specifically, after the ARM module 120 generates the display data, the display data may be transmitted to the FPGA module 130, so that the FPGA module 130 may push the display data to the head-end receiving card 201 through the first network interface 111, and may receive the display data returned by the tail-end receiving card 206 through the second network interface 112. The first network port 111 and the second network port 112 may be network ports located on the FPGA module 130, or may be network ports separately arranged in the transmitting card 100.
On the basis of the above technical solution, optionally, the FPGA module 130 is further configured to push the display data to the tail-end receiving card 206 through the second internet access 112 in a reverse direction when the second internet access 112 cannot receive the display data returned by the tail-end receiving card 206, so that the display data are sequentially transmitted from the tail-end receiving card 206 to the receiving cards with normal network connections in a reverse direction. Specifically, when the second network port 112 cannot detect the data transmitted from the first network port 111, it indicates that there is a network disconnection between the receiving cards, at this time, the FPGA module 130 may convert the function of the second network port 112 from monitoring to transmitting, and reversely push the display data to the tail-end receiving card 206 through the second network port 112, and further may transmit the display data according to the reverse direction of the original data transmission direction of each receiving card in the cascade connection, so that the receiving card after the network disconnection position in the original data transmission direction may obtain the required display data, thereby implementing the normal use of the display screen. For example, as shown in fig. 2, assuming that the network between the third receiving card 203 and the fourth receiving card 204 is disconnected, the FPGA module 130 may sequentially transmit the display data to the head-end receiving card 201, the second receiving card 202, and the third receiving card 203 through the first network interface 111, and may further sequentially transmit the display data to the tail-end receiving card 206, the fifth receiving card 205, and the fourth receiving card 204 through the second network interface 112, so that each receiving card may obtain the required display data.
Based on the above technical solution, optionally, the ARM module 120 is further configured to determine that a network fault exists between the receiving cards in the cascade connection when the second internet access 112 cannot receive the display data returned by the tail end receiving card 206.
Further optionally, as shown in fig. 2, the transmitting card 100 further includes a networking module 140, and the ARM module 120 is further configured to upload the fault information to the cloud server 300 through the networking module 140 when it is determined that the network fault exists, so that a user can obtain the fault information from the cloud server for further processing. The networking module 140 may specifically use network connection modes such as WIFI, 4G, and a wired network.
Further optionally, as shown in fig. 2, the cloud server 300 includes a device access module 310 and an information notification module 320, where the device access module 310 is configured to receive the fault information uploaded by the sending card 100 and transfer the fault information to the information notification module 320, and the information notification module 320 is configured to notify a user of the fault information. When a network fault occurs, the fault information can be actively notified to the user, so that the user can check and process the screen body in time, and the influence time of the fault is reduced. Optionally, the information notification module 320 may be specifically configured to invoke an operator interface (such as mobile, unicom, and telecom), and notify the fault information to the user through a short message.
On the basis of the above technical solution, optionally, as shown in fig. 2, the system further includes an advertisement screen box 400 corresponding to the receiving card one to one, and configured to receive and display the display data pushed by the corresponding receiving card. Specifically, each receiving card can push the display data to the corresponding advertisement screen box 400 while receiving the display data, so that the advertisement screen box 400 can display the display data according to the received display data.
The multifunctional adapter plate provided by the embodiment of the invention comprises a sending card and a plurality of cascade-connected receiving cards, wherein the sending card pushes display data to the cascade-connected head-end receiving cards through a first network port, and receives the display data transmitted back by the tail-end receiving cards after being transmitted by each cascade-connected receiving card through a second network port. When the second portal receives the display data, it can be determined that the network connection among the receiving cards in the cascade connection is good, and when the second portal cannot receive the display data, it can be determined that a network fault exists among the receiving cards in the cascade connection. Therefore, an active network fault detection function is provided for the unattended display screen, and a user can know the fault state in time conveniently.
