Description

Technical Field

[0001] The present invention relates to the technical field of image processing, and in particular, to a method for data synchronization and a video processing device. Background Art

[0002] In a large-screen display scenario, in order to realize the common display or separate display of business scenario images on multiple display screens, it is necessary to process a video source through a specific device and display it on the above-mentioned display screens. The specific device may include: a video splicer, which is a high-tech device that divides a complete image signal into N blocks and distributes them to N video display units. The video splicer can complete the composition of a super-large-screen dynamic image display screen with multiple ordinary video units, and can support the simultaneous connection of multiple video devices. The video splicer can realize the combination of multiple physical outputs into a super-high-resolution display output after resolution superposition, so that the screen wall constitutes a super-high-resolution, super-high-brightness, and super-large-display-size logical display screen, and completes various display functions such as window opening, moving, and zooming of multiple signal sources on the screen wall.

[0003] As a high-tech device for display, the video splicer is widely used in railways (subways, railway stations, high-speed rails), airports, docks, port surveillance systems, safe city command centers, national defense or military surveillance systems, intelligent transportation supervision systems, power dispatching monitoring systems, financial management monitoring systems, large-scale factory and mine monitoring systems, television stations / large studio monitoring curtain walls, video conferences, large performance venues, and shopping malls and other advertising demonstration occasions. Its application occasions determine that the device must have extremely high stability. In large-scale performances and other occasions, a picture interruption is a serious accident.

[0004] In the application of related technologies, in order to avoid the occurrence of picture interruption accidents, related technologies usually use a method of mutual backup between two main controls. In the case of a problem with one of the main controls, the other main control takes over the device, so as to ensure the continuous controllability of the device. Among them, data needs to be synchronized in real time between the two main controls to ensure that the main control taking over the device can correctly take over. However, there is often a problem of firmware parameter incompatibility during the large-screen display process. If the firmware parameters are incompatible with the device parameters, it will cause abnormal display.

[0005] Regarding the above problem of abnormal display caused by the incompatibility between firmware parameters and device parameters, no effective solution has been proposed yet. Summary of the Invention

And although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in a different order than here.

[0031] Figure 1 is a flowchart of a data synchronization method according to an embodiment of the present invention, as Figure 1 shown, the method includes the following steps:

[0032] Step S102, obtain the operating state of the device;

[0033] Step S104, obtain the identity information of at least two master cards according to the above operating state;

[0034] Step S106, determine the main card and the secondary card according to the identity information of the above at least two master cards;

[0035] Step S108, send the information to be synchronized of the above main card to the above secondary card for synchronization, where the information to be synchronized includes: display data and firmware information.

[0036] Among them, the display data may include: in the case where one of the master cards is the main card, the display parameters and display data in the master card that controls the display process; the display data may be the image data in the large-screen display process.

[0037] The firmware information may include: the software version information in the master card.

[0038] In the embodiment of the present invention, by obtaining the operating state of the device; obtaining the identity information of at least two master cards according to the above operating state; determining the main card and the secondary card according to the identity information of the above at least two master cards; sending the information to be synchronized of the above main card to the above secondary card for synchronization, where the information to be synchronized includes: display data and firmware information, the purpose of avoiding display anomalies caused by incompatibility between firmware parameters and device parameters is achieved, thereby realizing the technical effect of improving the operating stability of the device, and further solving the technical problem of display anomalies caused by incompatibility between firmware parameters and device parameters.

[0039] Optionally, the above device may be a video splicer, and at least two master cards are provided in the video splicer. Taking the example of two master cards provided in the above video splicer, for example Figure 2 shown, there are master card 1 and master card 2 provided in the above video splicer, and a processor is provided in the backplane (this attachment Figure 2(not shown in the figure), the processor is connected to the main control card 1 and the processor is connected to the main control card 2 through a serial port (for sending identity information) and a network (e.g., gigabit network, for synchronizing data), and the processor, the main control card 1, and the main control card 2 are respectively connected to external devices.

[0040] It should be noted that, in the embodiments of the present application, the main control card 1 and the main control card 2 are backup to each other. If the currently working main control card has an abnormality, it will switch to the standby main control card to perform work, so as to ensure that the video splicer can still operate normally, effectively improving the system stability of the video splicer.

[0041] Optionally, the identity information of the above main control card includes: the ID number of the product (e.g., the unique identity code, determining whether the main control card is the main card or the secondary card through the slot where the main control card is located. If it is in the main slot, it is marked as the main card; if it is in the secondary slot, it is marked as the secondary card).

[0042] In an optional embodiment, the above operating state includes: the operating state of the above device is the start-up state of a new device, the operating state of the above device is the device restart state, or a card in the above device is abnormal.

[0043] In an optional embodiment, obtaining the identity information of at least two main control cards according to the above operating state includes:

[0044] Step S202, when the operating state of the above device is the start-up state of a new device, sending the product information of the backplane to the above at least two main control cards;

[0045] Step S204, respectively obtaining the identity information of the main control cards located in the main slot and the secondary slot.

[0046] In the above optional embodiment, taking two of the above main control cards as an example, since after the new device is powered on, neither of the two main control cards has saved the product information (the SN code of the backplane) of the device, the processor will send the product information (e.g., SN code information) of the device to the two main control cards for storage. By storing the SN code of the backplane, the identity confirmation and permission confirmation are completed between the main control card and the backplane during the subsequent communication process, so as to ensure the normal progress of subsequent data interaction. When determining the main card and the secondary card of the two main control cards, by respectively obtaining the identifiers of the main control cards located in the main slot and the secondary slot, the identity information of each main control card is determined, where the identity information includes: the main card or the secondary card.

[0047] In an optional embodiment, determining the main card and the secondary card according to the identity information of the above at least two main control cards includes:

[0048] Step S302: Obtain the first identity information of the above main control card through the above main slot, and determine the main control card located in the above main slot as the above main card according to the above first identity information; wherein, the first identity information may include: the identifier of the main slot, and the identifier of the main slot is used to indicate that the main control card is located in the main slot, so that the backplane can determine the main control card as the main card according to this identifier.

[0049] Step S304: Obtain the second identity information of the above main control card through the above secondary slot, and determine the main control card located in the above secondary slot as the above secondary card according to the above second identity information. Wherein, the second identity information may include: the identifier of the secondary slot, and the identifier of the secondary slot is used to indicate that the main control card is located in the secondary slot, so that the backplane can determine the main control card as the secondary card according to this identifier.

[0050] In the embodiment of the present application, the processor (the processor in the backplane, such as an MCU) obtains the first identity information of the above main control card through the above main slot, and takes the main control card located in the main slot as the main card and uses this main card to take over the device during the current time, switches the control interface of the peripheral device to the current main card, obtains the second identity information of the above main control card through the above secondary slot, and takes the main control card located in the main slot as the secondary card (i.e., the standby card, backup card).

[0051] In an optional embodiment, obtaining the identity information of at least two main control cards according to the above operating state includes:

[0052] Step S402: When the operating state of the above device is the device restart state and the above identity information includes the timestamp of the data and the product information, receive the timestamp of the above data and the above product information sent by the above at least two main control cards.

[0053] In the above optional embodiment, if it is obtained that the operating state of the above device is the device restart state, then at least two main control cards respectively send the timestamp of the current data and the recorded product information to the processor.

[0054] As an optional embodiment, at least two main control cards may send the above identity information to the processor through the serial port.

[0055] In an optional embodiment, as Figure 3 shown, determining the main card and the secondary card according to the identity information of the above at least two main control cards includes:

[0056] Step S502: Judge whether the above product information sent by the above at least two main control cards is the same as the pre-stored product information;

[0057] Step S504, in the case where the judgment result is negative, when there is a piece of the above product information sent by one main control card that is the same as the above pre-stored product information, determine the above main control card as the above main card, and the main control cards other than the above main control card as the above secondary cards; or, when the above product information sent by the above at least two main control cards is different from the pre-stored product information, determine the main control card located in the main slot as the above main card;

[0058] Step S506, in the case where the judgment result is positive, determine the main control card whose distance between the time stamp of the above data and the current time point is less than the threshold as the above main card; when the time stamps of the above data sent by each main control card are the same, determine the main control card located in the main slot as the above main card.

[0059] In the embodiment of the present application, after the processor receives the product information sent by at least two main control cards, it respectively determines whether the product information sent by the at least two main control cards is the same as the pre-stored product information (i.e., the SN code of the backplane).

[0060] As an alternative embodiment, when there is a piece of the above product information sent by one main control card that is the same as the above pre-stored product information, determine the above main control card as the above main card, and the main control cards other than the above main control card as the above secondary cards; or, when the above product information sent by the above at least two main control cards is different from the pre-stored product information, determine the main control card located in the main slot as the above main card.

[0061] As an alternative embodiment, when the above product information sent by the above at least two main control cards is the same as the pre-stored product information, then obtain the distance between the time stamp of the data between the at least two main control cards and the current time point, and use the main control card with a distance less than the threshold as the main card; when the time stamps of the data sent by each main control card are the same, use the main control card located in the main slot as the main card.

[0062] In an alternative embodiment, as Figure 4 shown, the above sending the information to be synchronized of the above main card to the above secondary card for synchronization includes:

[0063] Step S602, send the synchronization request of the above secondary card to the above main card;

[0064] Step S604, send the display data and firmware information in the information to be synchronized of the above main card to the above secondary card according to the synchronization request of the above secondary card;

[0065] Step S606, perform data synchronization on the above secondary card according to the above display data and the above firmware information.

[0066] Still taking the example of two main control cards, when the identities of the main card and the secondary card of the two main control cards are confirmed, the secondary card will send a synchronization request to the processor, and the processor will forward the synchronization request to the main card to request synchronization of the current display data and firmware information to the secondary card. After obtaining the display data and firmware information, the secondary card will be synchronized according to the above display data and the above firmware information.

[0067] As an optional embodiment, data synchronization of the secondary card may be performed via a network (eg, a precursor network) but is not limited thereto.

[0068] In an optional embodiment, the above method further includes:

[0069] Step S702: After the data synchronization is completed, the secondary card is in a state of waiting for the primary card to update, so as to receive the changed data sent by the primary card and synchronize the timestamp of the data.

[0070] As an optional embodiment, the main card starts normal business and starts another thread to synchronize display data and firmware information to the secondary card. After the synchronization is completed, the secondary card is in a state of waiting for the main card to be updated, receiving the changed data sent by the main card at any time, and synchronizing the timestamp of the data.

[0071] In an optional embodiment, if Figure 5 As shown, the above method also includes:

[0072] Step S802, receiving heartbeat packets from the primary card and the secondary card respectively;

[0073] Step S804, when the time for the master card to send the heartbeat packet is greater than a preset time, determining that the operation state of the master card is abnormal;

[0074] Step S806, resetting the primary card and switching the peripherals to the secondary card;

[0075] Step S808, determining that the secondary card is changed to the primary card, and using the changed primary card to perform data processing and transmission.

[0076] As an optional embodiment, after the device is powered on normally and the identity confirmation of the primary and secondary cards is completed, both the primary card and the secondary card will maintain the interaction of heartbeat packets with the processor. Optionally, the heartbeat packets can be sent through the serial port.

[0077] In the above optional embodiment, once the current main card has no heartbeat interaction for a long time, that is, the time for the main card to send the above heartbeat packet is greater than the preset time, it will be considered that the current main card is working abnormally, and the main-subsidiary card switching process will be started, that is, the main card will be reset, and the peripherals will be switched to the sub-card, and then the changed main card will perform data processing and transmission.

[0078] Through the data synchronization solution provided by the embodiments of the present application, by setting at least two main control cards, the backplane determines the identities of the main card and the secondary card through double verification of data and SN. During the power-on recovery process without replacing the card, the main card used by the previous device will be used to take over the device. Even if it is replaced with another main control card, since the display data and firmware information of the device are stored in this main control card, it can be determined that the other main control card takes over the device, ensuring that the device can restore the state before shutdown every time it is powered on, and can synchronize the previous data and firmware of the device to the newly replaced main control card.

[0079] Moreover, in the embodiments of the present application, during the normal operation of the device, the working state of the current main card is confirmed by checking the heartbeat. Once an abnormality occurs, the current main card and secondary card will be switched, and the secondary card will continue to manage the device, without problems such as device freezing, improving the stability of the device.
