In the embodiment of the application, the large-screen display system can be a television wall system or other display systems with large-size screens, and when the large-screen display system is a television wall system, the large-screen display system can be a television wall screen and can be a system formed by a comprehensive security management platform, decoding equipment, an LCD display screen or an LED transmitting card. The comprehensive security management platform mainly comprises a service framework, a television wall service component, a control client framework, a television wall client component, a World Wide Web (Web) client and an Application (APP) client. For convenience of description, the description is mainly made with respect to the case that the large-screen display system is a video wall system, and the principle is the same for other cases, and only differences are described below.

Next, a detailed description will be given of a fault diagnosis method of the large-screen display system provided in the embodiment of the present application through a specific embodiment.

The fault diagnosis method of the large-screen display system provided by the embodiment of the application can be applied to electronic equipment, specifically, the electronic equipment can be a desktop computer, a portable computer, an intelligent mobile terminal and the like, and for convenience of description, the electronic equipment is taken as an execution main body for carrying out the following exemplary description, and the following examples do not limit the application.

Referring to fig. 2, fig. 2 is a schematic flow chart of a fault diagnosis method of a large screen display system provided in an embodiment of the present application, where the method is applied to an electronic device, and the electronic device may be integrated on any device such as a large screen, an output device, or may be an additional device independent of the devices; the video wall service referred to below may be deployed on electronic devices, output devices, etc. as well as on other devices. The large screen display system includes a large screen and an output device, the large screen being divided into a plurality of screen units in advance according to pre-configured wall information, as shown in fig. 2, including the steps of:

step S21: generating a topological graph comprising nodes and connecting lines according to the wall information, wherein each node in the topological graph is used for representing each device included in the large-screen display system, and each connecting line is used for representing the connection relation between each device in the large-screen display system.

Step S22: and determining whether the equipment represented by the node and the connection relation represented by the connection line are abnormal or not according to each connection line and each node in the topological graph.

Step S23: and marking the nodes with the abnormal represented equipment in the topological graph, and marking the connecting lines with the abnormal represented connection relations to obtain the marked topological graph.

Step S24: the noted topology is shown.

According to the technical scheme provided by the embodiment of the application, the topological graph comprising the nodes and the connecting lines can be automatically generated according to the pre-configured wall information; and then confirm whether there is abnormality in the connection relation that the apparatus that node represents and connecting line represent, if there is abnormality, label the node or connecting line that can have abnormality in the topological graph, get the topological graph already marked, and demonstrate the topological graph already marked, in this way, present the node or connecting line with abnormality to users in a visual way, facilitate users to know the cause of abnormality visually, raise the efficiency to deal with the abnormal problem.

In the above step S21, when the large-screen display system is a video wall system, the video wall service component is preconfigured with wall information, and the electronic device may access the video wall service component to obtain the preconfigured wall information. The preconfigured wall information may include information such as a television wall name, a television wall specification, a connection relationship between devices in the television wall, and the like, and the television wall specification may be the number of screens, the screen size, and the like, that is, the number of large screens divided into screen units in the television wall system and the size of each screen unit may be determined according to the television wall specification.

Therefore, the electronic equipment can generate a topological graph comprising nodes and connecting lines according to wall information, namely the specification of the television wall, the connection relation among the devices in the television wall and the like, wherein each node in the topological graph can be used for representing each device in the television wall system, and each connecting line in the topological graph can be used for representing the connection relation among the television wall systems.

It can be understood that the large screen in the large screen display system can be an LCD screen or an LED screen, when the large screen in the large screen display system is an LCD screen, the devices in the large screen display system can include a large screen and an output device, the connection relationship between each device in the large screen display system can include the connection relationship between the output device and the large screen, and if the large screen is divided into a plurality of screen units, the connection relationship between the output device and the large screen can be understood as the connection relationship between each output port on the output device and each screen unit on the large screen; when the large screen in the large screen display system is an LED screen, the equipment in the large screen display system can also comprise a sending card and a receiving card besides the large screen and the output equipment, and the connection relation between the equipment in the large screen display system can comprise the connection relation between the output equipment and the sending card, the connection relation between the sending card and the large screen and the like.

Meanwhile, for output equipment in the large-screen display system, when the large screen in the large-screen display system is a small-scale screen, the output equipment can be decoding equipment; when the large screen in the large screen display system is a large screen, the output device may be a decoding device and a spelling control device. When the output device is a decoding device and a spelling control device, the connection relationship between the devices in the large screen display system may also include the connection relationship between the decoding device and the spelling control device.

When the large-screen display system comprises a sending card and a spelling control device and the signal source is a high-definition signal source, the large screen in the large-screen display system is a large-scale screen, otherwise, if the large-screen display system does not comprise the sending card or the spelling control device or the signal source is not the high-definition signal source, the large screen in the large-screen display system is a small-scale screen.

In the step S22, the electronic device determines whether the connection lines and the nodes in the topology map are abnormal, that is, whether the connection relationships between the devices in the large-screen display system are abnormal, for example, whether the parameter configuration of each output port on the output device in the video wall system is abnormal, whether the connection relationship between each output port on the output device and the screen unit is abnormal, and the like. The manner of determining whether each node and each link in the topology map have an abnormality will be described in detail later, and will not be described here again.

In step S23, after the electronic device executes step S12, if it is determined that an abnormality exists in a certain connection line or a certain node in the topology, the connection relationship indicated by the connection line having the abnormality in the topology or the device indicated by the node having the abnormality may be marked, for example, the color of the connection line having the abnormality may be marked as a color different from that of the other connection line (i.e., the connection line having no abnormality), the node corresponding to the device having the abnormality may be marked with a frame, and the labeled topology may be further obtained.

In some embodiments, after determining that the device or the connection relationship is abnormal, the electronic device may further indicate the device or the connection relationship with the abnormality in the topology map in text form, and indicate the cause of the abnormality, so that the existing abnormality problem can be more directly displayed to the user, which is convenient for the user to determine the abnormality problem in time, and improves the efficiency of processing the abnormality problem.

In some embodiments, the electronic device may acquire the screen information of each screen unit and display the acquired screen information, for example, after the electronic device acquires the screen information, the electronic device may display the acquired screen information at a node representing the screen unit in the topology map, or may display the acquired screen information at any other position in the topology map, which is not limited.

In this embodiment of the present application, the screen information may include a screen position number, a serial number, software version information, an operation duration, a temperature, output port information, an output port state, and a decoding output port. Wherein, the screen position number may be understood as the current position number of the screen unit, and as illustrated in fig. 3, four screen units are sequentially numbered 1-1, 1-2, 2-1 and 2-2 in the order from top to bottom and from left to right, it is understood that the illustration in fig. 3 is only one possible example provided in the application, and in other possible cases, the screen units may be numbered in other order, for example, from top to bottom, from right to left, from bottom to top, and from left to right, and the example illustrated in fig. 3 is not limited in any way; the serial number can be understood as the serial number corresponding to the screen unit, and the software version information can be understood as the version information of the software for generating the large-screen display system; the operation time can be understood as the operation time of the screen unit; the temperature can be understood as the current temperature information of the screen unit; the output port information can be understood as parameter information of the output port on the output device corresponding to the screen unit, such as resolution, frame rate, etc.; the output port state can be understood as the working state of the output port on the output device corresponding to the screen unit; the decoding output port may be understood as the number of the output port on the output device to which the screen unit corresponds.

When the large screen display system is a television wall system, the electronic equipment can access the output equipment through the television wall service to acquire the output port state and output port information of each output port on the output equipment, and meanwhile, the output equipment can acquire screen information such as screen position numbers, serial numbers, running time and the like of each screen unit in the television wall system through a private protocol (such as CEC or EDID), so that the electronic equipment can acquire the screen information of each screen unit.

It can be understood that when the large screen in the television wall system is an LCD screen, the output device can directly acquire screen information from each screen unit through a private protocol; when the large screen in the television wall system is an LED screen, the screen unit and the output equipment are connected through the sending card and the receiving card, at the moment, the output equipment can acquire screen information of the corresponding screen unit from the sending card through a private protocol, and receive a screen position number returned by the sending card and the receiving card information.

In the embodiment of the application, besides the equipment and the connection relation with the abnormality are highlighted in the topological graph in the marked form, the screen information of each screen unit is displayed, so that after the user determines the abnormality problem, the screen information of each screen unit can be known in time, and the existing abnormality problem can be effectively solved through the screen information of the screen unit. If the output device is marked on the topological graph, the output device is indicated to be abnormal, and the reason for the abnormality is that the parameter configuration of the output port is wrong, a user can timely determine the parameter information of the current configuration of the output port on the output device according to the screen information displayed on the topological graph, so that the abnormal parameter can be conveniently and timely changed, whether the changed parameter is normal or not is determined, and the efficiency of solving the abnormal problem is improved.

In the step S24, after the electronic device obtains the annotated topology, the annotated topology may be displayed, and the abnormal problem may be visualized.

In response to a user instruction, the electronic device can display a large screen at any one of a web client, an APP client and a CS (client-Server), namely, the large screen is used for displaying video data, when an abnormality exists, the marked topological graph can be displayed at the client which displays the large screen at present, and the user can conveniently and timely determine the abnormality problem. Or when no abnormality exists, the electronic device can display the unlabeled topological graph to the client, so that a user can know the structure of the current large-screen display system and screen information of each screen unit conveniently.

Next, the method of determining whether or not there is an abnormality in each node and each link in the topology map in step S12 will be described below.

It can be understood that the normal operation of the large-screen display system mainly includes three phases, the first phase may be a process of configuring parameter information of each device and connection relation between each device in the large-screen display system, the second phase may be a process of transmitting video data to a corresponding screen unit for display, and the third phase may be a process of normally displaying video data on the corresponding screen unit, and the three phases are all generated without abnormality, so that the normal operation of the large-screen display system can be realized. Therefore, for each stage, the possible abnormality of each node and each connection line in the topology graph at the stage can be examined, after the current stage has no abnormality, the next stage is executed, for example, when the current stage is in the first stage, the first stage is the process of configuring the parameter information of each device in the large-screen display system and the connection relation between each device, the possible abnormality in the stage is the configuration abnormality of the parameter information of each device in the television wall or the connection relation between each device, the stage can determine whether the parameter information configuration of the devices represented by each node in the topology graph is abnormal or whether the connection relation represented by each connection line in the topology graph is abnormal, if the first stage has abnormality, the abnormality can be eliminated until the first stage has no abnormality, and then the second stage is executed. Thus, the abnormal problem can be rapidly eliminated in advance, and the efficiency of solving the abnormal problem is improved. In the following, a method of determining whether or not there is an abnormality in each node and each link in the topology is described by taking the above three phases as examples.

The first stage is a process of configuring parameter information of each device and connection relation between each device in the large screen display system, and whether each node and each side in the topological graph have abnormality can be determined by the following modes 1-3.

Mode 1: aiming at each output port of the output device, acquiring the current connection state of the output port and the preset connection state preset for the output port; if the current connection state of the output port is inconsistent with the preset connection state preset for the output port, determining that the connection relationship between the output port and the screen unit is abnormal.

In this embodiment of the present application, the output port is each output port on the output device, and the current connection state of the output port may be understood as whether the output port is currently connected with a screen unit, and the preset connection state of the output port may be understood as whether the output device is connected with a screen unit under the preset condition. After the electronic equipment obtains the current connection state and the preset connection state of each output port on the output equipment, comparing the current connection state and the preset connection state of each output port, and if the output port with the inconsistent current connection state and the inconsistent preset connection state exists, indicating that the connection relationship between the output port and the screen unit is abnormal. At this time, the connection relationship between the output port and the screen unit may be marked by displaying the connection line representing the connection relationship between the output port and the screen unit in the topology chart as a color inconsistent with other connection lines, or displaying a special symbol on the connection line representing the connection relationship between the output port and the screen unit, so as to prompt that the connection relationship between the output port and the screen unit is abnormal, and the abnormality is because the current connection state of the output port is inconsistent with the preset connection state.

Mode 2: for each output port of the output device, acquiring an identifier for representing a screen unit currently connected with the output port as a first identifier; if the screen unit represented by the first identifier is inconsistent with the second identifier corresponding to the screen unit which is connected with the preset output port, determining that the connection relationship between the output port and the screen unit is abnormal.

Each screen unit corresponds to a unique identifier, which may be a screen position number of the screen unit or a serial number of the screen unit, and in some examples, when the large screen is an LCD screen, the identifier of the screen unit may be a screen serial number of the screen unit; when the large screen is an LED screen, the identification of the screen unit can be the sending serial number of the screen unit. The screen unit to which the outlet is preset to be connected may be understood as a screen unit to which the outlet should be connected in the preset case. The electronic equipment can acquire the identifiers of the screen units currently connected with each output port on the output equipment, the identifiers are used as first identifiers, the first identifiers are compared with second identifiers of the screen units which are preset to be connected with the output ports, and if the first identifiers and the second identifiers corresponding to the output ports are inconsistent, the abnormal connection relation between the output ports and the screen can be determined.

For example, the output device comprises two output ports, namely an output port 1 and an output port 2, respectively, a large screen in the large screen display system is divided into two screen units in advance, namely a screen unit 4 and a screen unit 5, the identification of the screen unit 4 is an identification 4, and the identification of the screen unit 5 is an identification 5; the mark of the screen unit preset connected by the output port 1 is a mark 4 (namely, a second mark corresponding to the output port 1), and the mark of the screen unit preset connected by the output port 2 is a mark 5 (namely, a second mark corresponding to the output port 2); the identification of the screen unit currently connected with the output port 1, which is acquired by the electronic equipment, is an identification 5 (namely, a first identification corresponding to the output port 1), and the identification of the screen unit currently connected with the output port 2 is an identification 4 (namely, a first identification corresponding to the output port 2); through comparison, it can be determined that the first identifier corresponding to the output port 1 is inconsistent with the second identifier, and the first identifier corresponding to the output port 2 is inconsistent with the second identifier, so that it can be determined that the connection relationship between the output port 1 and the screen unit is abnormal, and the connection relationship between the output port 2 and the screen unit is also abnormal.

It can be understood that the topology map is generated according to wall information, and the wall information includes preset connection relations between the devices, so that screen units connected with the output ports on the output device in the topology map are preset connected screen units for the output ports. Continuing with the above embodiment as an example, the screen unit connected to the current output port 1 is the screen 5, the screen unit connected to the output port 2 is the screen 4, but in the topology diagram, the screen unit connected to the output port 1 is the screen 4, and the screen unit connected to the output port 2 is the screen 5; at this time, the connection line between the output port 1 and the screen 4 and the connection line between the output port 2 and the screen 5 can be marked to show that the connection relationship between the output port 1 and the screen 4 is abnormal and the connection relationship between the output port 2 and the screen 5 is abnormal.

In some embodiments, the above-mentioned modes 1 and 2 are modes in which the connection relationship between the output port of the output device and the screen unit is abnormal, but the reason for causing the connection relationship abnormality in mode 1 is that the current connection state of the output port is inconsistent with the preset connection state, the reason for causing the connection relationship abnormality in mode 2 is that the identity of the screen unit currently connected to the output port is inconsistent with the identity of the preset connected screen unit, that is, the reason for causing the connection relationship abnormality in mode 1 and mode 2 is not the same, so that the modes for labeling the connection relationship with abnormality may be different for mode 1 and mode 2, and if it is determined that there is an abnormality in the connection relationship in mode 1, the connection relationship with abnormality determined in mode 1 may be displayed as a color that is not used for other connection relationships; when it is determined that the connection relationship is abnormal in the mode 2, the special identifier can be displayed on the connection relationship determined in the mode 2 and having the abnormality, so that not only the connection relationship having the abnormality can be intuitively represented, but also the reason for the connection relationship having the abnormality can be intuitively represented.

Mode 3: acquiring parameter information of at least one core parameter in a large-screen display system; if the target parameter information in the abnormal state is determined to exist through verification, determining that the equipment to which the target parameter information belongs is abnormal;

When the large-screen display system does not comprise a sending card and a receiving card, the core parameters in the large-screen display system can be configuration parameters of all output ports of the output device; when the large-screen display system comprises a sending card and a receiving card, the core parameters in the television wall system can be the configuration parameters of all the output ports on the output equipment, the configuration parameters of the sending card connected with all the output ports and the configuration parameters of the receiving card connected with all the output ports.

When the large-screen display system is a television wall system, the electronic equipment can acquire parameter information of core parameters in the television wall system through television wall service at fixed time, and check the acquired parameter information, and if target parameter information in an abnormal state exists, the equipment to which the target parameter information belongs can be determined to have abnormality. If the parameter information of the output port 1 on the output device is in an abnormal state after verification, the parameter information of the output port 1 is the target parameter information, and the output device can be determined to be abnormal.

The foregoing modes 1 to 3 are only 3 exemplary abnormality determination modes that can be used in the first stage provided in the present application, and in one possible embodiment, only some of them may be used, for example, only modes 1 and 3, and also, for example, only mode 1 may be used, and in another possible embodiment, the diagnosis may be performed together in modes 1 to 3, and in yet another possible embodiment, the diagnosis may be performed in modes 1 to 3 and other diagnostic modes, which is not limited in any way.

The second stage is a process of displaying video data on the corresponding screen unit, and it can be determined whether or not there is an abnormality in each node and each link in the topology map in the following manner 4-manner 6.

Mode 4: the output device establishes communication connection with a plurality of input devices, the input devices are used for sending video data to the output devices, and the output devices are used for receiving and decoding the video data; if the output device cannot acquire video data from the input device or the output device cannot decode the video data, it may be determined that the output device is abnormal.

In this embodiment of the present application, the output device receives the video data, if the video data is in an encrypted state, the video data needs to be decoded, and after decoding is completed, the video data can be displayed in the large screen. If the output device cannot receive the video data sent by the input device or the output device cannot decode the video data, it may be determined that the output device has an abnormality. That is, when video data provided by the output device is to be received in a specific manner, but the capability of the output device does not support the specific manner, the output device cannot obtain video data from the input device, and it can be determined that there is an abnormality in the output device; for example, when video data is streamed by a domain name mode and streaming media is streamed, but the capability of the output device is not supported, the output device cannot receive the video data, and it can be determined that an abnormality exists in the output device, at this time, a prompt can be given in a topology graph for indicating the cause of the abnormality, for example, the output device can be displayed in the topology graph without supporting streaming media domain name streaming, or the streaming abnormality is displayed in the topology graph; or when the video data is an encrypted code stream, and the output device receives the video data, but the output device does not support the encrypted code stream, that is, the output device cannot decode the video data, it may be determined that the output device has an abnormality.

Mode 5: nodes used for representing all screen units are included in the topological graph, and whether the resolution of video data sent to the screen units meets the resolution requirement preset for the screen units is determined for all the screen units; if the resolution of the video data sent to the screen unit does not meet the resolution requirement of the screen unit, the screen unit has an abnormality.

For each screen unit, before the video data is sent to the corresponding screen unit for display, the electronic device may acquire the resolution of the video data, further determine whether the resolution of the video data meets the resolution requirement preset by the corresponding screen unit, and if the resolution of the video data sent to a certain screen unit does not meet the resolution requirement of the screen unit, determine that the screen unit has an abnormality. The preset resolution requirement of the screen unit may be that the pixel point of the video data displayed in the screen unit is a multiple of a preset value, for example, the pixel point of the video data displayed in the screen unit is a multiple of 16, and the preset value may be set according to the actual situation; alternatively, the preset resolution requirement of the screen unit may be that the number of pixels of the video data displayed in the screen unit is greater than a preset number, and the preset number may be set according to the actual situation.

In some embodiments, when the large-screen display system is a video wall system, the video wall service may determine whether the minimum window parameter requirement is met according to whether the signal source (i.e. the video data) on the upper wall is a splicing source type and a splicing source input specification, and if the minimum window parameter requirement is not met, may determine that an abnormality exists in a screen unit corresponding to the signal source.

Mode 6: acquiring a decoding state of the output equipment within a preset time after the output equipment receives the video data; if the decoding state of the output device indicates that the output device is not decoded, determining that the output device is abnormal.

In the embodiment of the application, the decoding state of the output device may indicate whether the output device is already decoding. And in the preset time after the output equipment receives the video data, the electronic equipment can acquire the decoding state of the output equipment, and if the decoding state which is output and set indicates that the output equipment is not decoded, the abnormality of the output equipment can be determined. The preset time may be set according to actual situations, for example, may be set to 3 seconds, 4 seconds, 5 seconds, and the like. For the case of batch operation on-wall, the decoding state of the decoding device can be obtained through the television wall service via the batch interface, and for the case of non-batch operation on-wall, the decoding state of the decoding device can be directly obtained. ,

Mode 7: the method comprises the steps of periodically aiming at each output port of output equipment, obtaining the current connection state of the output port and the preset connection state preset for the output port; if the current connection state of the output port is inconsistent with the preset connection state preset for the output port, determining that the connection relationship between the output port and the screen unit is abnormal. I.e. periodically, in the second phase, the inspection is performed as in the above-described mode 1. It will be understood that, if the abnormality is detected in the mode 1, it can only be indicated that the connection relationship between the output port and the screen unit is normal when the mode 1 is executed, and then the connection relationship between the output port and the screen unit in the large-screen display system may change during the use, and the connection relationship after the change may be abnormal, so that it is necessary to periodically perform inspection according to the mode 1.

The foregoing modes 4 to 7 are only 3 exemplary abnormality determination modes that can be used in the first stage provided in the present application, and in one possible embodiment, only some of them may be used, for example, only modes 1 and 3, and also, for example, only mode 1, and in another possible embodiment, the diagnosis may be performed together in modes 4 to 6, and in yet another possible embodiment, the diagnosis may be performed in modes 1 to 3 and other diagnostic modes, which is not limited in any way.

The third stage is a process of normal display of video data on the corresponding screen unit, and it can be determined whether each node and each link in the topology map have abnormality in the following manner 7.

Mode 8: at least one preset abnormal event and equipment corresponding to each preset abnormal event are preset for the large-screen display system in advance; the preset abnormal event is used for indicating an abnormal event possibly existing in the process of sending the video data from the input device to the large screen, and comprises at least one of the following abnormal events: the decoding resources of the output equipment are insufficient, the secret key input by the output equipment cannot decode the video data, the input equipment is in an offline state, and the video data is abnormal; monitoring a large screen display system to obtain a monitoring result; if the monitoring result indicates that the large-screen display system has the preset abnormal event, determining that the equipment corresponding to the preset abnormal event has the abnormality.

In this embodiment, for a large-screen display system, the electronic device may set at least one preset abnormal event and a corresponding device, that is, may set a corresponding device for the preset abnormal event while setting the preset abnormal event, so when a monitoring result obtained by monitoring the large-screen display system indicates that a certain preset abnormal event exists, the preset abnormal event may be directly displayed at a node corresponding to the device in the topology map.

In some embodiments, the corresponding device configured for the preset abnormal event may be a device that causes the preset abnormal event to occur, for example, when the preset abnormal event is that the decoding resource of the output device is insufficient, the preset abnormal event is caused by the output device, so that the device corresponding to the preset abnormal event (i.e. that the decoding resource of the output device is insufficient) may be configured as the output device, and when the preset abnormal event exists, the preset abnormal event may be displayed at the node corresponding to the output device in the topology map; similarly, when the preset abnormal event is that the screen unit a cannot be displayed normally, the preset abnormal event can be displayed at the node corresponding to the screen unit a in the topological graph when the preset abnormal event exists. When the preset abnormal events are events caused by the devices outside the large-screen display system, such as offline state processing of the input device, abnormal video data, and the like, the devices corresponding to the events can be set as output devices according to actual requirements, so that the preset abnormal events are displayed at the nodes corresponding to the output devices in the topological graph when the preset abnormal events exist, and the devices corresponding to the events can be set as arbitrary screen units, so that the preset abnormal events are displayed at the nodes corresponding to the screen units in the topological graph when the preset abnormal events exist.
