Description

Technical Field

[0001] The embodiments of the present invention relate to the field of LED control technology, and in particular to a method, device, equipment and medium for detecting abnormal data of a network port of an LED sending card. Background Art

[0002] With the rapid development of the information age, the utilization rate of LED display screens is getting higher and higher. For LED sending cards, in order to maximize the number of LED screen points carried by a single network port, general LED sending cards use Gigabit Ethernet to send in the form of customized RGB packets. This use of a customized protocol packet sending mechanism greatly reduces the bandwidth overhead of the Ethernet protocol, thereby improving the utilization of the network port bandwidth.

[0003] However, compared with the TCP / IP transmission protocol with a retransmission mechanism, the custom RGB transmission protocol does not have a retransmission mechanism, but transmits data at the fastest rate. Therefore, the custom transmission protocol is an unreliable transmission protocol. When designing the hardware and debugging the software of the sending card, network port data errors and data packet loss are often encountered, which will cause noise, flickering, and flowery screens on the LED display. At present, the data transmission anomalies of the LED sending card are generally detected by manually observing whether there are flickers or noises on the LED display, which is very time-consuming. In addition, the severity of the anomalies varies in different environments, and some minor anomalies are difficult to observe, which affects the reliability of the research and development conclusions.

[0040] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0041] It should be mentioned before discussing the exemplary embodiments in more detail that some exemplary embodiments are described as processes or methods depicted as flow charts. Although the flow charts describe the steps as sequential processes, many of the steps therein can be implemented in parallel, concurrently or simultaneously. In addition, the order of the steps can be rearranged. The process can be terminated when its operation is completed, but can also have additional steps not included in the accompanying drawings. The process can correspond to a method, function, procedure, subroutine, subprogram, etc.

[0042] Embodiment 1

[0043] Figure 1 This is a flow chart of the method for detecting abnormal data of the network port of the LED sending card provided in the first embodiment of the present invention. This embodiment can be applied to the situation where it is necessary to detect abnormal data provided by the LED sending card to the LED screen display system during the development of the LED sending card and related products. The method can be executed by the device for detecting abnormal data of the network port of the LED sending card provided in the embodiment of the present invention. The device can be implemented by hardware and / or software, and can generally be integrated into the detection equipment. Figure 1 As shown, the specific steps include:

[0044] S11, obtain the network port data output by the LED sending card.

[0045] S12: Analyze the network port data to obtain the network port control range and data packet protocol information.

[0046] S13, determining theoretical packet transmission information per frame according to the network port control range and the data packet protocol information.

[0047] S14. Determine actual packet transmission information for each frame according to the network port data.

[0048] S15. Compare the actual packet sending information per frame with the theoretical packet sending information per frame to obtain an abnormality detection result of the network port data.

[0049] Specifically, Figure 2 As shown, the detection device can be connected to the network port output end of the LED sending card through the network port, so as to receive the network port data output by the LED sending card through the network cable. The network port data is transmitted in the form of data packets. Each frame of data can correspond to multiple data packets, and the network port control range and data packet protocol information can be carried in the frame header, so that the detection device can obtain it by parsing the network port data. Among them, the frame header refers to a characteristic data packet with a position delimiter of a specific identification sequence. There is one at the starting position of each frame, which can be used to mark the beginning or end of a frame. The data packet between two frame headers is the data packet corresponding to a frame. The network port control range can include the control width X and control height Y of the network port of the LED sending card to which it is connected. The data packet protocol information can be used to declare the number of pixels that can be transmitted by a valid data packet. For example, a 256-pixel protocol can be used, that is, a protocol for transmitting 256 pixel data in a valid data packet. A 512-pixel padded protocol can also be used, that is, a protocol for transmitting 512 pixel data in a valid data packet, and so on.

[0050] After parsing and obtaining the network port control range and data packet protocol information, the theoretical packet information per frame can be determined based on the network port control range and data packet protocol information, that is, the data packet situation that the LED sending card should send within one frame time in theory, as a standard for judging whether there is any abnormality in packet sending. On the other hand, after obtaining the network port data output by the LED sending card, the actual packet sending information per frame can also be obtained based on the statistics of the network port data actually received, that is, the data packet situation that the LED sending card actually sends within one frame time. Then the actual packet sending information per frame can be compared with the theoretical packet sending information per frame. When the actual situation is different from the theoretical situation, it means that there is an abnormality in the packet sending of the LED sending card, and the specific abnormal content can be further obtained by statistics.

[0051] Wherein, optionally, the theoretical packet sending information per frame includes the theoretical number of packets sent per frame and / or the theoretical row and column packet ordering per frame; the actual packet sending information per frame includes at least one of the actual number of packets sent per frame, the actual data packet ordering per frame, and the actual row and column packet ordering per frame. Wherein, the row and column packet refers to the number of packets in the row or column of the data packet. For each frame of data, each corresponding data packet can have its own row and column packet sequence number to identify the row or column of the data packet.

[0052] Specifically, after parsing the network port control range and data packet protocol information, the theoretical number of packets sent per frame can be calculated based on the network port control range and data packet protocol information, that is, how many data packets should a frame of data contain in theory, and the theoretical maximum packet sequence number can be obtained. At the same time, the actual number of packets sent per frame can be statistically obtained based on the network port data actually received, and the corresponding packet sequence number can be parsed in real time based on the packet header information of each received data packet, thereby obtaining the actual order of packets per frame. Then the actual number of packets sent per frame can be compared with the theoretical number of packets sent per frame to determine whether they are consistent, that is, to determine whether the total number of data packets is normal. It can also be determined based on the theoretical maximum packet sequence number whether there is a packet sequence number error in the actual order of packets per frame, and the specific abnormal position can be determined. Among them, the packet header refers to a serial number with a certain identifier as the identification header of the data packet to mark the boundary of a packet of valid data. Each data packet has a packet header for identification, and the valid data therein is the data actually used for LED display control.

[0053] After parsing the network port control range and data packet protocol information, the theoretical row and column packet ordering per frame can be calculated based on the network port control range and data packet protocol information. For example, the number of data packets required to transmit a row of data can be calculated based on the control width and the number of pixels that can be transmitted by each data packet, and the sequence number of the last packet in a row can be obtained. At the same time, the number of rows contained in a frame of data can be determined based on the control height, so that the theoretical row and column packet ordering per frame can be determined, that is, the row and column packet sequence number of each data packet in a frame of data in theory. For the network port data actually received, the corresponding row and column packet sequence number can be parsed in real time based on the packet header information of each received data packet, so as to obtain the actual row and column packet ordering per frame. Then, based on the theoretical row and column packet ordering per frame, it can be determined whether there is an error in the row and column packet sequence number in the actual row and column packet ordering per frame, and the specific abnormal position can be determined.

[0054] Furthermore, the theoretical frame rate of the current data transmission and the theoretical interval between frames can be calculated based on the network port control range and the data packet protocol information. At the same time, the actual number of frame headers can be counted based on the actual received network port data, so as to determine whether the total number of frames is normal.

[0055] On the basis of the above technical solution, optionally, after obtaining the network port data output by the LED sending card, it also includes: parsing the network port data to obtain the theoretical CRC check number of each data packet; performing a secondary check based on the valid data of each data packet in the network port data to generate a corresponding actual CRC check number; comparing the actual CRC check number with the theoretical CRC check number, and supplementing the abnormal detection result according to the comparison result. Specifically, the corresponding theoretical CRC check number can be obtained in real time according to the packet header information of each received data packet, and the valid data in each received data packet can be secondary checked in real time to generate the corresponding actual CRC check number. Then the actual CRC check number is compared with the corresponding theoretical CRC check number to obtain the corresponding error packet information as the abnormal detection result.

[0056] On the basis of the above technical solution, optionally, before determining the theoretical packet transmission information of each frame according to the control range of the network port and the data packet protocol information, it also includes: confirming that the connection status with the network port output end of the LED sending card is normal; parsing the network port data, and confirming that a preset number of frame header valid flags have been detected. Specifically, at the beginning of the abnormal detection process, the connection status of the network port can be obtained by first reading the register status of the local PHY chip. After confirming that the connection status with the network port output end of the LED sending card is normal, the frame synchronization information can be obtained by parsing the frame header information in the received network port data. When it is confirmed that a preset number, such as 60 frame header valid flags, is detected, it can be considered that the detection environment has been stable, so that the subsequent detection process can be better started.

[0057] Based on the above technical solution, optionally, after comparing the actual packet transmission information per frame with the theoretical packet transmission information per frame to obtain the abnormality detection result of the network port data, it also includes: sending the abnormality detection result to the host computer in real time for display. Specifically, Figure 2 As shown, the detection device can be connected to the host computer and can send the abnormal detection results to the host computer through the serial port in real time. The host computer can further count and analyze the received abnormal detection results for use by R&D personnel.

[0058] Based on the above technical solution, optionally, after obtaining the network port data output by the LED sending card, it also includes: sending the network port data to the LED screen display system in real time to control the LED display screen to display. Figure 2As shown, the detection equipment can be connected to the existing LED screen display system through the network port, and can send the network port data received from the LED sending card to the LED screen display system intact in real time, so as to achieve abnormal detection without affecting the control of the LED sending card over the LED display screen, so as to facilitate R&D personnel to analyze the abnormal situation actually displayed on the screen.

[0059] The technical solution provided by the embodiment of the present invention first obtains the network port data output by the LED sending card, then parses the network port data to obtain the network port control range and data packet protocol information, and then determines the theoretical packet sending information per frame based on the network port control range and data packet protocol information. At the same time, the actual packet sending information per frame can be determined based on the obtained network port data, so that the actual packet sending information per frame can be compared with the theoretical packet sending information per frame to obtain the abnormal detection result of the network port data of the LED sending card. By counting the actual packet sending situation and comparing it with the theoretical situation, the automatic monitoring of the abnormal network port data of the LED sending card is realized, and the abnormal situation can be accurately counted, which provides a reliable basis for the stability and reliability of related products, greatly improves the efficiency of correcting the abnormal state of the product during the research and development process, and saves a lot of research and development costs.
