Therefore, the matching accuracy of the data interface is further ensured.
For ease of understanding, the interface matching detection method performed by the interface matching detection system 10 is described below with reference to fig. 1 to 4.
Taking a plurality of, for example, two display control cards R11-R12 electrically connected to the data interface 1 of the display screen controller 12 as an example, as shown in fig. 2, the working modes of power-on initialization of the two display control cards R11-R12 are: each display control card sends a node discovery packet and a training packet from a network port A and a network port B respectively, three bytes after a destination MAC address field in the node discovery packet are 0xFFFFFF for example, the content in the node discovery packet carries a physical address of the display control card and an identifier of the network port corresponding to the node discovery packet respectively, the training packet sends current identifier information after the network port A and the network port B are trained, and six bytes in the destination MAC address field in the training packet are 0 xFFFFFFFFFFFFFF for example.
More specifically, the initial identification information of the internet access a and the internet access B of the display control card R11 are (R11, a) and (R11, B), respectively, and the current identification information after training is (R11, a) and (R12, a), respectively; the initial identification information of the internet access a and the internet access B of the display control card R12 are (R12, a) and (R12, B), respectively, and the current identification information after training is (R11, B) and (R12, B), respectively. Here, the display control card R11 is a target display control card adjacently connected to the data interface 1 of the display screen controller 12, and the portal a of the display control card R11 is a target portal adjacently connected to the data interface 1 of the display screen controller 12. The network port a and the network port B of the display control card R11 output a node discovery packet containing the initial identification information (R11, a) and a node discovery packet containing the initial identification information (R11, B), respectively, and the network port a and the network port B of the display control card R12 output a node discovery packet containing the initial identification information (R12, a) and a node discovery packet containing the initial identification information (R12, B), respectively; the portal a and the portal B of the display control card R11 each output a training packet containing current identification information (R11, a) and (R12, a), and the portal a and the portal B of the display control card R12 each output a training packet containing current identification information (R11, B) and (R12, B).
In view of the above, the node discovery packet including the initial identification information (R11, a) sent by the portal a of the display control card R11 is input to the display screen controller 12 from the data interface 1, and the display screen controller 12 analyzes the node discovery packet to identify the initial identification information (R11, a) of the portal a corresponding to the target display control card (i.e., the first-level display control card under the data interface 1). Then, the display screen controller 12 receives two training packets from the data interface 1, namely, the training packet generated by the display control card R11 and containing the current identification information (R11, a) and (R12, a) and the training packet generated by the display control card R12 and containing the current identification information (R11, B) and (R12, B), and parses them respectively.
When the training packet including the current id information (R11, a) and (R12, a) is parsed, it is found that (R11, a) of the parsed current id information (R11, a) and (R12, a) is the same as the previously identified initial id information (R11, a), and then the next-stage display control card R12 of the display control card R11 can be determined according to the parsed current id information (R11, a) and (R12, a) of the (R12, a).
When the training packet including the current identification information (R11, B) and (R12, B) is parsed, it is found that the physical address (R11) of one display control card of the parsed current identification information (R11, B) and (R12, B) is the same as the physical address of the display control card of the recognized initial identification information (R11, a), but the identification (B) of the portal corresponding to the physical address (R11) is different from the identification (a) of the portal of the recognized initial identification information (R11, a), and it is also found that the physical address (R12) of the other display control card of the parsed current identification information (R11, B) and (R12, B) is the same as the determined physical address of the display control card R12, and it is determined that the R12 of the next display control card of the display control R11 is the last-stage display control card.
Thus, it can be recognized that each display control card R11-R12 under the data interface 1 of the display screen controller 12 obtains a corresponding physical address set as { R11, R12 }. In short, the display screen controller 12 of this embodiment first recognizes the node discovery broadcast packet to synchronously recognize the first-level display control card R11 and the identifier a of the internet access connected to the data interface 1, and then recognizes the subsequent display control card R12 through the training packet. The display screen controller 12 recognizes a physical address set corresponding to the display control card connected to the data interface 1, stores the physical address set in the local, and then sends a data reading instruction to the upper computer 11, where the data reading instruction includes, for example, an identifier of the data interface 1 and the number of the display control cards connected to the data interface 1.
The upper computer 11 will receive the imported offline configuration file, analyze the offline configuration file, and display an offline display screen wiring diagram as shown in fig. 2, for example. And then receiving and responding to a data reading instruction, wherein the mentioned data reading instruction comprises an interface identifier corresponding to a data interface of the display screen controller and the number of display control cards. The upper computer 11 receives the data reading instruction and then sends a data reading instruction to the display screen controller 12, where the data reading instruction includes, for example, the aforementioned interface identifier and the number of bytes of the physical address corresponding to each display control card. And the display screen controller 12 receives the reading quantity instruction and then sends the physical address set required by the upper computer 11 to the upper computer. After the upper computer 11 reads the physical address set { R11, R12} corresponding to the data interface 1 stored in the display screen controller 12, it sends a model request instruction to the display control card R11 and the display control card R12 according to the read physical address corresponding to the display control card R11 and the physical address corresponding to the display control card R12 connected to the data interface 1. The display control card R11 and the display control card R12 respond to the model request instruction respectively to reply the model of the display box corresponding to the display box carried by the display control card R. The mentioned display box body is, for example, an LED box body, the mentioned model of the display box body is, for example, an ID number, and when the LED box body leaves a factory, if the size, the driver IC, and the model of the display control card corresponding to each LED box body are the same, the model of the LED box body can be represented by a uniform ID number, which can be understood as that the model of the LED box body leaving the factory in the same batch is the same.
After the upper computer 11 obtains the information, the following judgment is carried out: firstly, judging whether the model of the display box body in the offline configuration information obtained by analyzing the offline configuration file is the same as the model of the display box body read back actually, if so, carrying out the subsequent judgment process, and if not, indicating that the matching fails, prompting on an interface and not carrying out the following judgment. And after the model of the display box is successfully matched, the number of the display control cards connected with the data interface is matched, if the model of the display box is successfully matched, the data interface is successfully matched, and if the model of the display box is not successfully matched, the data interface is failed. Specifically, the upper computer 11 matches the display box models corresponding to the received display control card R11 and display control card R12 with the offline display box models in the offline configuration information; when the received display box model is the same as the offline display box model in the offline configuration information, matching the number 2 of the display control cards corresponding to the data interface 1 with the number of the offline display control cards corresponding to the offline display control cards connected to each offline data interface in the offline configuration information, and then finding that the number 2 of the display control cards connected to the data interface 1 is the same as the number of the offline display control cards corresponding to the offline display control cards connected to the offline data interface 1 in the offline configuration information, so as to represent that the offline data interface 1 in the offline configuration information is matched with the data interface 1.
As shown in fig. 4, for example, the data interface M of the display screen controller 12 is electrically connected to a plurality of, for example, four display control cards Rm1-Rm2 and Rn1-Rn2, as shown in fig. 4, the power-on initialization operation modes of the four display control cards Rm1-Rm2 and Rn1-Rn2 are as follows: each display control card sends a node discovery packet and a training packet from a network port A and a network port B respectively, three bytes after a destination MAC address field in the node discovery packet are 0xFFFFFF for example, the content in the node discovery packet carries a physical address of the display control card and an identifier of the network port corresponding to the node discovery packet respectively, the training packet sends current identifier information after the network port A and the network port B are trained, and six bytes in the destination MAC address field in the training packet are 0 xFFFFFFFFFFFFFF for example.
More specifically, the initial identification information of the internet access a and the internet access B of the display control card Rm1 are (Rm1, a) and (Rm1, B), respectively, and the current identification information after training is (Rm1, a) and (Rm2, a), respectively; displaying the initial identification information of the internet access A and the internet access B of the control card Rm2 as (Rm2, A) and (Rm2, B), respectively, and the current identification information after training as (Rm1, B) and (Rn2, B), respectively; displaying initial identification information of a network port A and a network port B of the control card Rn2 as (Rn2, A) and (Rn2, B), respectively, and current identification information after training as (Rn1, B) and (Rm2, B), respectively; the initial identification information of the port a and the port B of the control card Rn1 are shown as (Rn1, a) and (Rn1, B), respectively, and the trained current identification information is shown as (Rn1, a) and (Rn2, a), respectively. Here, the display control card Rm1 is a target display control card adjacently connected to the data interface M of the display screen controller 12, and the network port a of the display control card Rm1 is a target network port adjacently connected to the data interface M of the display screen controller 12; the net port a and the net port B of the display control card Rm1 output a node discovery packet containing initial identification information (Rm1, a) and a node discovery packet containing initial identification information (Rm1, B), respectively, the net port a and the net port B of the display control card Rm2 output a node discovery packet containing initial identification information (Rm2, a) and a node discovery packet containing initial identification information (Rm2, B), respectively, the net port a and the net port B of the display control card Rn2 output a node discovery packet containing initial identification information (Rn2, a) and a node discovery packet containing initial identification information (Rn2, B), respectively, the net port a and the net port B of the display control card Rn1 output a node discovery packet containing initial identification information (Rn1, a) and a node discovery packet containing initial identification information (Rn1, B), respectively; the net port a and the net port B of the display control card Rm1 each output a training packet containing current identification information (Rm1, a) and (Rm2, a), the net port a and the net port B of the display control card Rm2 each output a training packet containing current identification information (Rm1, B) and (Rn2, B), the net port a and the net port B of the display control card Rn2 each output a training packet containing current identification information (Rn1, B) and (Rm2, B), and the net port a and the net port B of the display control card Rn1 each output a training packet containing current identification information (Rn1, a) and (Rn2, a).
As described above, the node discovery packet including the initial identification information (Rm1, a) sent by the internet access a of the display control card Rm1 is input to the display screen controller 12 from the data interface M, and the display screen controller 12 analyzes the node discovery packet to identify the initial identification information (Rm1, a) of the internet access a corresponding to the target display control card (i.e., the first-level display control card under the data interface M). Thereafter, the display screen controller 12 receives four training packets from the data interface M, i.e., the training packet generated by the display control card Rm1 and containing the current identification information (Rm1, a) and (Rm2, a), the training packet generated by the display control card Rm2 and containing the current identification information (Rm1, B) and (Rn2, B), the training packet generated by the display control card Rn2 and containing the current identification information (Rn1, B) and (Rm2, B), and the training packet generated by the display control card Rn1 and containing the current identification information (Rn1, a) and (Rn2, a), and parses them respectively.
When the training packet including the current identification information (Rm1, a) and (Rm2, a) is parsed, it is found that (Rm1, a) of the parsed current identification information (Rm1, a) and (Rm2, a) is the same as the recognized initial identification information (Rm1, a), and the next-level display control card Rm2 of the control card display Rm1 is determined according to the parsed current identification information (Rm1, a) and (Rm2, a) of the (Rm2, a).
When parsing the training packet including the current identification information (Rm1, B) and (Rn2, B), it is found that the physical address (Rm1) of one display control card of the parsed current identification information (Rm1, B) and (Rn2, B) is the same as the physical address of the display control card of the identified initial identification information (Rm1, A), but the identification (B) of the portal corresponding to the identification (Rm1) is different from the identification (A) of the portal of the identified initial identification information (Rm1, A), and further finding that the other display control card's physical address (Rn2) of the parsed current identification information (Rm1, B) and (Rn2, B) is different from the previously determined physical address of the display control card Rm2, then, the second-level display control card Rn2 of the display control card Rm1 can be determined according to the analyzed current identification information (Rm1, B) and (Rn2, B) in the (Rn2, B).
When the training packet including the current identification information (Rn1, B) and (Rm2, B) is analyzed, the physical address (Rm2) of one display control card in the analyzed current identification information (Rn1, B) and (Rm2, B) is the same as the physical address of the determined display control card Rm2, but the physical address (Rn1) of the other display control card is different from the physical address of the determined display control card Rn2, and then the last three-level display control card Rn1 of the display control card Rm1 can be determined according to the analyzed current identification information (Rn1, B) and (Rm1, B) in the analyzed current identification information (Rn1, B) and (Rm2, B).
When parsing the training packet including the current identification information (Rn1, a) and (Rn2, a), it is found that the physical addresses (Rn1) and (Rn2) of the two display control cards in the parsed current identification information (Rn1, a) and (Rn2, a) are the same as the determined physical addresses of the display control card Rn1 and the display control card Rn2, respectively, and it is determined that the display control card Rn1 is the last display control card. Thus, the physical address sets { Rm1, Rm2, Rn2, Rn1} corresponding to the display control cards Rm1-Rm2 and Rn1-Rn2 under the data interface M of the display screen controller 12 can be identified. In short, the display screen controller 12 of this embodiment first identifies the node discovery broadcast packet to synchronously identify the first-level display control card Rm1 and the identifier a of the network port connected to the data interface M, and then identifies the next display control cards Rm2 and Rn1-Rn2 through the four training packets.
After obtaining the physical address set corresponding to the data interface M, the display screen controller 12 stores the physical address set corresponding to the data interface M and sends a data reading instruction to the upper computer 11.
The upper computer 11 similarly performs the above operation, and thus it can be determined that the data interface M is matched with the offline data interface M in the offline configuration information.
When the upper computer 11 detects that the offline data interfaces 1-M in the offline configuration information are matched with the data interfaces 1-M of the display screen controller 12 in a one-to-one correspondence manner, it indicates that the offline display screen controller corresponding to the offline data interfaces 1-M in the offline configuration information is matched with the display screen controller 12. In addition, it should be noted that, when the number of the display control cards connected to the plurality of offline data interfaces is the same, a situation that matching is successful may also exist, but actually, matching of the corresponding data interface identifiers may be wrong, in this situation, the upper computer 11 sends image data to the LED display screen for image display, a debugger may see the display effect of the LED display screen to detect whether matching is correct, and may perform manual adjustment on the upper computer 11 under the condition that matching fails, for example, drag to change the position of the display control card corresponding to the offline data interface with the wrong data interface identifier in the offline display screen connection diagram.
