In order to better understand the technical solutions provided by the embodiments of the present application, the following detailed description is made with reference to the drawings and specific embodiments.
The display system comprises a display screen and a display control system, wherein the display screen comprises a plurality of display units, the display system comprises a plurality of display boxes, and each display box comprises one or more display units and corresponding receiving cards. Once the receiving card fails, the display unit in the display screen controlled by the receiving card cannot normally display, and the mounting and connection complexity of the display box body is high, so that the failure reasons of the receiving card in the display box body are more, in the prior art, workers check the failure reasons of the receiving card one by one according to experience, the time spent is long, and the detection efficiency is low.
In view of this, an embodiment of the present application provides a fault detection method, and an application scenario related to the embodiment of the present application is introduced below.
Referring to fig. 1A, an application scenario schematic diagram of a fault detection method is provided for the embodiment of the present application, or may be understood as a structural diagram of a display system, where the display system includes a display control system and a display screen 140, and the display control system includes an upper computer 110, a sending card 120, and a receiving card 130. The receiving card 130 includes a failure processing module 150 and a video data module 160. The video data module 160 is used for receiving the video data of the transmitting card 120 and controlling the display screen 140 to display video frames. The failure processing module 150 in the embodiment of the present application is used to detect the failure of the video data module 160. The fault handling module 150 and the video data module 160 are two separate modules that may be independent of each other. In fig. 1A, the display control system includes 4 receiving cards as an example, and the number of the receiving cards is not limited in practice.
Referring to fig. 1B, a schematic structural diagram of a display control system according to an embodiment of the present disclosure is shown, where the display control system includes an upper computer 110, a sending card 120, and a plurality of receiving cards 130, where the plurality of receiving cards 130 are specifically the receiving cards a to F in fig. 1B, and each receiving card is used to control one or more display units in a display screen 140.
The functions of the various modules in the display system are described below:
under the condition that the video data module 160 is normal, the upper computer 110 sends the acquired video data to the sending card 120, the sending card 120 compresses the acquired video data and sends the compressed video data to the receiving card 130, after the receiving card 130 receives the compressed video data, the video data module 160 decompresses and processes the compressed video data to generate a driving signal and sends the driving signal to the display screen 140, and the display screen 140 displays a video frame corresponding to the driving signal according to the received driving signal.
Various faults that may occur during the operation of the video data module 160 may result in the display screen 140 not displaying video frames normally. In case that the video data module 160 is abnormal, the fault handling module 150 of the receiving card 130 may detect a fault of the video data module 160 and, if it is determined that the video data module 160 has a fault, display the fault information on the display screen 140 in a visual manner. The fault detection method will be described below.
Based on the application scenario discussed in fig. 1A, a fault detection method related to the embodiment of the present application is described below.
Referring to fig. 2, a flowchart of a fault detection method according to an embodiment of the present application is shown, where the method includes:
s201, if the fault processing module 150 determines that the video data module has a fault, the fault processing module obtains a fault type corresponding to the video data module.
The fault processing module 150 pre-stores possible fault types corresponding to the video data module 160 and corresponding fault detection methods, and the fault processing module 150 performs real-time fault detection on the video data module 160 according to the pre-stored fault detection methods. The fault types comprise initialization abnormity, network port packet error, network port packet loss, parameter configuration abnormity, state abnormity and the like.
During the actual operation process, the fault handling module 150 detects whether a corresponding fault exists in the video data module 160 according to a pre-stored fault detection method. A fault detection method may detect one or more fault types, as illustrated below:
1. the fault handling module 150 detects a fault type using a fault detection method:
the fault processing module 150 detects whether a fault with abnormal parameter configuration exists in the video data module 160 by using a fault detection method for detecting whether all parameters in the video data module 160 conform to preset parameters.
2. The fault handling module 150 detects at least two fault types using a fault detection method:
the fault processing module 150 sends a test packet to the video data module 160, detects whether the video data module 160 receives the test packet, and whether the received test packet is the test packet sent by the fault processing module 150, and if the video data module 160 does not return a confirmation packet to the fault processing module 150, it indicates that a fault that the video data module 160 has a network port packet loss is detected; if the video data module 160 returns an acknowledgement packet to the fault handling module 150, but the returned acknowledgement packet is not a test packet sent by the fault handling module 150, it indicates that there is a fault of a network interface error packet in the video data module 160.
After the receiving card 130 is powered on, the fault processing module 150 may sequentially and cyclically execute a plurality of fault detection methods, or simultaneously execute a plurality of fault detection methods, and according to the corresponding fault detection method, if it is detected that the video data module 160 has a fault, determine a fault type corresponding to the video data module 160 according to the corresponding fault detection method.
For example, if the fault processing module 150 detects that some parameters in the video data module 160 do not conform to the preset parameters, it is determined that the video data module 160 has a fault, and according to the fault type associated with the fault detection method, it may be determined that the fault type corresponding to the video data module 160 is a parameter configuration abnormality.
S202, the fault processing module 150 determines a target fault graph corresponding to the fault type from the graph generation scheme.
The fault handling module 150 stores a graph generation scheme in advance, where the graph generation scheme includes at least one fault type and a fault graph corresponding to each fault type, and each fault graph is used to graphically display the corresponding fault type. For example, the color or shape of the failure pattern is different for different failure types, which is illustrated below:
(1) The fault graphs corresponding to different fault types are distinguished and represented by different colors and the same shape.
The failure processing module 150 pre-stores colors corresponding to different failure types, and the shapes corresponding to the different failure types are the same. This approach may be adapted to situations where the display elements of the display screen 140 are only capable of displaying a single shape, but the display elements may be color-changing.
For example, for the fault type of the initialization anomaly, the corresponding fault pattern is a red square; aiming at the fault type of the network port error packet, the corresponding fault pattern is a yellow square; and aiming at the fault type of network port packet loss, the corresponding fault graph is a black square and the like.
(2) The fault graphs corresponding to different fault types are distinguished and represented in different shapes and the same color.
The fault processing module 150 pre-stores the shapes corresponding to different fault types, and the colors corresponding to different fault types are the same. This approach may be adapted to situations where the display unit of the display screen 140 is capable of displaying different shapes.
For example, a plurality of fault types may be encoded, and the fault graph corresponding to each fault type is a number corresponding to the fault type.
Or for example, for the fault type of the initialization exception, the corresponding fault pattern is a red circle; aiming at the fault type of the network port error packet, a corresponding fault graph is a red square; and aiming at the fault type of the network port packet loss, the corresponding fault graph is a red rhombus and the like.
(3) The fault graphs corresponding to different fault types are represented by different shapes and different colors.
The failure processing module 150 pre-stores colors corresponding to different failure types and shapes corresponding to different failure types. This approach may be adapted to situations where the display unit is capable of displaying different shapes as well as different colors.
For example, for the fault type of the initialization anomaly, the corresponding fault pattern is a red circle; aiming at the fault type of the network port error packet, the corresponding fault pattern is a yellow square; and aiming at the fault type of the network port packet loss, the corresponding fault graph is a black rhombus and the like.
After determining the fault type corresponding to the video data module 160, the fault processing module 150 determines a target fault pattern corresponding to the fault type from the pattern generation scheme.
For example, the fault pattern corresponding to the initialization anomaly in the pattern generation scheme is a red circle, the fault processing module 150 determines that the fault type corresponding to the video data module 160 is the initialization anomaly, and according to the pattern generation scheme, determines that the target fault pattern of the video data module 160 at this time is a red circle.
The data type of the failure pattern may be, for example, image or pattern information, and the processing manner of the failure processing module 150 is different according to the data type of the failure pattern, which is explained as follows:
a, the data type of the failure pattern is an image.
The data type of the failure pattern pre-stored in the pattern generation scheme is the image itself, and the failure processing module 150 directly reads the image of the failure pattern from the pattern generation scheme after determining that the video data module 160 has a failure.
And B, the data type of the fault graph is graph information.
The data type of the failure graph pre-stored in the graph generation scheme is graph information, and the failure processing module 150 reads the graph information from the graph generation scheme after determining that the video data module 160 has a failure, and generates an image in real time according to the graph information.
In one possible embodiment, the fault handling module 150 may also receive user input of a graphical generation scheme to augment or extend its own stored graphical generation scheme.
S203, the fault processing module 150 generates a first driving signal according to the target fault pattern.
After determining the target failure pattern of the video data module 160, the failure processing module 150 may generate a first driving signal corresponding to the target failure pattern according to the target failure image, so as to instruct the display screen 140 to display the target failure pattern.
Since different display screens may have different chips and different formats of the driving signals corresponding to different chips, in this embodiment of the application, the receiving card 130 generates the driving signal in a format adapted to the chip according to the chip used by the display screen, so that the generated driving signal can normally drive the display unit in the display screen 140 to display.
S204, the fault processing module 150 sends the first driving signal to a display unit in the display screen, so that the display unit displays a target fault pattern.
The display screen 140 includes one or more display units, for example, the display screen 140 is an LED display screen, and a plurality of LED lamps correspond to one display unit. Each display unit corresponds to one receiving card, so that the receiving card 130 controls the target display unit corresponding to itself to display after determining the target failure image. After receiving the first driving signal sent by the fault processing module 150, the target display unit displays a target fault graph corresponding to the first driving signal on the target display unit.
The above is an example of a case where the video data module 160 has a fault, in another case, the video data module 160 may not have an abnormality, at this time, the video data module 160 may receive the video data sent by the sending card 120, the video data module 160 may generate a second driving signal according to the video data sent by the sending card, send the second driving signal to the target display unit of the display screen 140 through the fault processing module 150, and control the target display unit to display a video frame sent by the sending card.
In the embodiment of the present application, the fault handling module 150 not only detects a fault of the video data module 160, but also selectively sends the second driving signal of the video data module 160 to the display screen 140, and particularly, under the condition that the video data module 160 normally works, sends the second driving signal of the video data module 160 to the display screen 140, so that the display screen 140 can normally display. Further, in the case that the video data module 160 has a fault, the display screen 140 can be controlled to display a fault graph in a graphical manner, so that the fault of the video data module 160 can be detected and graphically displayed without affecting the normal operation of the display screen 140.
