[0039] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0040] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0041] The main solution of the embodiment of the present application is: obtaining the target input source of the switching instruction by the control module in response to the switching instruction of the data transmission module; selecting the original input source from the multiple input sources of the switching matrix module, wherein the original input source is any one of the multiple input sources currently output to the video matrix by the switching matrix module; controlling the switching matrix module to switch the original output port corresponding to the original input source in the current output to the video data input by the target input source.

[0042] At present, video surveillance systems based on network cameras and video matrices are widely used in command systems in the fields of municipal administration, public security, security, fire protection, electricity, and petroleum. However, the number of large screens in the video matrix is ​​usually far less than the number of network cameras. Therefore, the video content displayed in the video matrix is ​​very limited. When the video content monitored by the network camera is abnormal, it is often necessary to quickly output the corresponding monitoring video content to the video matrix for display, so that the video matrix can display emergency information in real time, providing information basis for the command system to make background strategy decisions at the video matrix end. Therefore, how to automatically switch the video that needs to be switched to the video matrix for display is a problem that needs to be solved urgently.

[0043] The present application provides a solution, which adopts a control module to respond to the switching instructions of the data transmission module, and operates the switching matrix module to select and switch the input source, thereby avoiding the inability to display the video content that needs to be monitored in a timely manner due to the limited number of large video matrix screens, and realizes fast and accurate automatic updating of the video matrix display content, ensuring that the video that needs to be switched can be output to the video matrix in an emergency, thereby improving the response speed and processing efficiency of the command system to emergency events.

[0044] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device that can realize the above functions. The following takes an electronic device as an example to illustrate this embodiment and the following embodiments.

[0045] Based on this, the embodiment of the present application provides a method for switching a video matrix, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the switching method of the video matrix of the present application.

[0046] In this embodiment, the switching method of the video matrix is ​​applied to a switching circuit of the video matrix, and the switching circuit includes a switching matrix module, a data transmission module, and a control module connected to the switching matrix module and the data transmission module respectively;

[0047] It should be noted that the video matrix refers to a display device used to centrally display multiple different video images, which is usually used in security monitoring, command and control centers, etc., so that operators can monitor and analyze multiple video images; the switching matrix module refers to the component responsible for receiving multiple video input signals and routing the selected input signal to the output port of the switching circuit according to the switching instruction for display, i.e., the video matrix; the data transmission module refers to the component in the switching circuit that loads transmission control signals (such as switching instructions) and data streams (such as monitoring videos). The component can ensure that the switching instructions and other related information can be effectively transmitted between the switching circuit and the external control system. The module can adopt at least one of the components including WiFi components, 5G components, Giga phy components and LCD (Liquid Crystal Display) components, wherein the Giga phy component is used to provide Ethernet connection; the control module refers to the management unit in the switching circuit. The control module load receives external control instructions (such as switching instructions from the operator or switching instructions automatically generated by the system) and converts them into signals that the switching matrix module can understand to control the switching process of the video input signal. The control module is usually a CPU (Central Processing Unit).

[0048] The video matrix switching method includes using the control module to perform steps S10 to S30:

[0049] Step S10, in response to the switching instruction of the data transmission module, obtaining a target input source of the switching instruction;

[0050] It should be noted that the switching instruction refers to a command transmitted from the data transmission module to the control module, which instructs the switching circuit to switch from the current display video source, i.e., the original input source, to another specific video source, i.e., the target input source. The instruction is usually automatically issued by the operator or the software system networked with the switching circuit in response to specific events or requirements summarized in the monitoring scene.

[0051] It is understandable that since it is often difficult in the command system to quickly and automatically switch to a specific monitoring screen according to actual conditions so that the operator or commander can respond quickly to emergency or important events, performing step S10 can avoid the operator or commander missing important information due to the inability to switch to the key video source in time in an emergency, thereby affecting the efficiency and results of event processing, and ensure that the command system can respond to switching instructions quickly and accurately, and display the key video source, i.e., the target input source, in real time on the large screen, i.e., the video matrix, thereby improving the monitoring operation efficiency and event response speed, and enhancing the real-time monitoring capability and decision support of the entire command system.

[0052] Step S20, selecting an original input source from the multiple input sources of the switching matrix module, wherein the original input source is any one of the multiple input sources currently output to the video matrix by the switching matrix module;

[0053] It should be noted that the input source refers to all possible video signal sources connected to the switching matrix module. These video signal sources can be web cameras, video recorders, computer signals, etc., which provide images and data in video surveillance; the original input source refers to the specific input source that is currently being output to the video matrix for display by the switching matrix module. In the switching circuit, each output port can be connected to one or more displays in the video matrix, and the original input source is the video signal source that has been assigned to these output ports.

[0054] It is understandable that, since it is difficult to accurately identify the video source that is currently displayed and needs to be replaced during the video content switching process in video surveillance, resulting in the inability to display key information in a timely manner, performing step S20 can avoid the inability to accurately identify and replace the currently displayed video source, thereby affecting the efficiency and accuracy of the command system's emergency response. By accurately identifying the currently displayed video source, a reliable basis is provided for replacing the video displayed in the video matrix, and more important video content can be displayed to the operator in real time, thereby improving the flexibility and response speed of video surveillance and enhancing the command system's real-time monitoring and processing capabilities for emergency events.

[0055] Step S30, controlling the switch matrix module to switch the original output port corresponding to the original input source in the current output to the video data input by the target input source.

[0056] It should be noted that the original output port refers to the output port occupied by the video signal currently output from the switching matrix module to the video matrix display, wherein the video signal comes from the original input source and is being displayed by a specific display in the video matrix; video data refers to the video signal obtained from the target input source, which contains important information that needs to be displayed immediately to the operator or commander in response to emergencies or specific events.

[0057] It is understandable that, since the current video surveillance system cannot automatically switch the key video source to the video matrix when an emergency or important event occurs to ensure that the operator or commander can see the most relevant information, performing step S30 can avoid the inability to quickly update the display content on the video matrix in an emergency, resulting in key information being ignored, thereby delaying the timing of emergency response, ensuring that the video surveillance can update the display content in real time and quickly display the most critical video information on the video matrix, thereby improving the emergency response capability and operational efficiency of the command system, thereby better responding to emergencies and ensuring safety.

[0058] The present embodiment provides a switching method for a video matrix, which adopts a control module to respond to the switching instructions of the data transmission module, and operates the switching matrix module to select and switch the input source, thereby avoiding the inability to timely display the video content that needs to be monitored due to the limited number of large screens of the video matrix, and realizing fast and accurate automatic updating of the video matrix display content, ensuring that the video that needs to be switched can be output to the video matrix in an emergency, thereby improving the response speed and processing efficiency of the command system to emergency events.

[0059] In a feasible implementation manner, the switching circuit runs an operating system configured with a soft bus, the data transmission module includes a networking module and a touch screen module, and the types of the switching instructions include a first switching instruction, a second switching instruction, and a third switching instruction;

[0060] It should be noted that the operating system is designed to run in the switching circuit to provide core functions and services, which may be KaihongOS (Kaihong Operating System) to provide the framework system of the OpenHarmony operating system, WiFi driver framework, 5G driver framework, USB driver framework, power management driver, Ethernet driver, HDMI switching matrix chip driver, HDMI input and output driver, etc.; the networking module refers to the component responsible for network communication in the switching circuit. This module enables the switching circuit to exchange data with external systems through the Internet or other networks. This module may adopt at least one of the components including WiFi components, 5G components and Giga phy components; the touch screen module refers to an input device in the switching circuit. This module allows the user to interact with the system where the switching circuit is located by directly touching the screen. It is used to detect the user's touch actions and convert them into commands that the system can understand, and provide an intuitive user operation interface. This module may be an LCD component.

[0061] Step S10 may include steps S11 to S13:

[0062] Step S11, in the case of receiving the first switching instruction transmitted by the event notifier to the networking module through the soft bus, in response to the first switching instruction, acquiring the target input source, wherein the first switching instruction is generated by the event notifier configured by the target input source among the multiple input sources, and the event notifier performs networking communication with the switching circuit based on the soft bus of the operating system;

[0063] It should be noted that the soft bus refers to a communication mechanism of the operating system, which allows different hardware modules and software components to exchange data and pass instructions through a unified interface, thereby achieving efficient communication within the system; the event notifier refers to a software module or service that is responsible for monitoring and detecting specific events in the system and generating corresponding notification instructions (such as switching instructions, etc.) when the event occurs. In this embodiment, it is used to detect the need for switching the surveillance video and generate a first switching instruction.

[0064] It is understandable that, since it is often impossible to switch the video input source in time by manual switching in an emergency situation, step S11 is performed. By responding to the first switching instruction generated and transmitted by the event notifier, delays and errors in manual switching of the input source can be avoided, thereby achieving rapid and automatic switching of the video source in an emergency situation.

[0065] Step S12, in the case of receiving the second switching instruction transmitted by the control device to the networking module through the soft bus, in response to the second switching instruction, acquiring the target input source, wherein the second switching instruction is generated by the control device that performs networking communication with the switching circuit based on the soft bus in response to the first switching operation of the monitoring video switching demand;

[0066] It should be noted that the control device refers to an external device, such as a control host, mobile phone, tablet computer, etc., which can communicate with the switching circuit through a soft bus and generate a control instruction, namely a second switching instruction, based on the monitoring video switching requirements.

[0067] It is understandable that, since in the actual video matrix monitoring process, the commander often has the need to manually switch the video displayed on the video matrix, step S12 is performed. By allowing the external control device to intervene in the video switching process, the target input source is acquired based on the second switching instruction transmitted via the network, which can avoid the complexity of directly operating the switching circuit and realize remote video source switching control.

[0068] Step S13, upon receiving the third switching instruction transmitted by the touch screen module, obtaining the target input source in response to the third switching instruction, wherein the third switching instruction is generated by the touch screen module in response to the second switching operation based on the monitoring video switching requirement.

[0069] It is understandable that since users are usually unable to perform intuitive visual interaction during the existing video matrix monitoring process, step S13 is performed to receive the third switching instruction through the set touch screen module to obtain the target input source, which can avoid the difficulty of users in intuitive interaction. It also avoids the inconvenience of traditional mechanical buttons or keyboard operations, and realizes more intuitive and quick video switching.

[0070] In this embodiment, by adopting soft bus-based communication technology, problems such as complex manual operation, response delay and easy errors in the traditional video switching process are avoided, and automatic input source switching, integration of remote control equipment and flexibility of touch screen interaction are realized, thereby achieving the effect of improving the system automation level and enhancing the convenience of operation.

[0071] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction, and will not be repeated in the following. Figure 2 , Figure 2 This is a flow chart of a second embodiment of a video matrix switching method of the present application.

[0072] The video matrix switching method includes using the control module to further perform steps S01-S02:

[0073] Step S01, obtaining a plurality of wired input sources connected to the switching matrix module via an HDMI high-definition multimedia interface;

[0074] It should be noted that the wired input source refers to a video signal source connected to the switching matrix module via HDMI (High Definition Multimedia Interface), which may include but is not limited to a high-definition camera, a Blu-ray player, a computer or other video output devices.

[0075] It can be understood that in order to ensure that the switching circuit can access a variety of different video signal sources, i.e., wired input sources, step S01 is performed, which can avoid the problem of insufficient video management function due to limitations on the type or number of video signal sources, thereby providing diversified video signal access capabilities and enhancing the applicability and flexibility of the system.

[0076] Step S02: using each of the wired input sources as a plurality of input sources of the switching matrix module.

[0077] It can be understood that in order to effectively integrate the video signal connected to the switching circuit into the switching matrix module for unified switching and control, step S02 is performed, which can avoid the complexity of managing each video signal source separately, reduce operational errors, improve system stability, simplify the management process of the video signal source, and thus improve the efficiency and reliability of video switching.

[0078] In a feasible implementation manner, the data transmission module at least includes a networking module, and step S02 may include steps S021 to S022:

[0079] Step S021, obtaining a network input source for networking communication with the networking module;

[0080] It should be noted that the network input source refers to a source that transmits video signals through a network protocol and a networking module (such as a WiFi component, a 5G component, a Giga phy component, etc.). The source may include a webcam, a network video encoder, a streaming media server, etc., which can communicate with the networking module through the network. In addition, the source may also include a control host, a mobile phone, a tablet computer and other control devices configured with an operating system (such as KaihongOS) with a soft bus. The control device can transmit the video content such as its own screen to the networking module based on the networking results of the soft bus, so as to display the screen of the control device on the video matrix.

[0081] It can be understood that in order to integrate the network video signal source so that the network video signal source can be managed uniformly by the switching matrix module together with the traditional wired video signal source, step S021 is performed. This can avoid the system function limitation problem caused by the inability to access the network video source, expand the signal source range of the switching circuit video input management, and increase the access capability of the network video signal.

[0082] Step S022: using the network input source and each of the wired input sources as multiple input sources of the switching matrix module.

[0083] It can be understood that in order to ensure that both the network input source and the wired input source can be uniformly managed and controlled by the switching matrix module, step S022 is performed, which can avoid the operational complexity and inconsistency when processing different types of input signal sources separately, and provide a unified management and control platform, thereby improving the operational efficiency of video switching and the flexible scheduling capability of signal sources.

[0084] In this embodiment, by networking to integrate network input signal sources and wired input signal sources as multiple input sources of the switching matrix module, the problem of being unable to uniformly manage and control due to different signal source types is avoided, and the network video signal and the traditional wired video signal are seamlessly integrated, thereby improving the compatibility and flexibility of video management, thereby improving the overall switching efficiency of the system.

[0085] In this embodiment, multiple wired input sources are connected to the switching matrix module and used as its input sources, which simplifies the management of video signal sources. By adopting HDMI, the reduction in video picture clarity due to poor signal transmission quality is avoided, and stable access and flexible switching of high-definition video signals are achieved, thereby improving the overall performance of video management.

[0086] For example, in order to help understand the principle block diagram of the switching circuit to which the video matrix switching method obtained by combining the present embodiment with the above-mentioned embodiment 1 is applied, please refer to Figure 3 , Figure 3 A principle block diagram of a video matrix switching method is provided, specifically:

[0087] In the figure, 1 is the motherboard of the switching circuit of the video matrix, 2 is the control core CPU as the control module, the control module can use RK3568 as the control core CPU, the CPU is connected to the networking module (WiFi module 4, 5G module 8 and Giga phy module 9 in the figure), the touch screen module (LCD module 6 in the figure), the USB*2 module and the switching matrix module (HDMI switching matrix chip 7 in the figure), wherein the CPU module is connected to the WiFi module through the PCIE2.0 interface (a high-speed serial computer expansion bus standard), that is, the CPU module can be connected to the Internet through the WiFi module; the CPU module is connected to the LCD module through the I2C interface for information display and touch control; the HDMIOUT interface of the CPU module, that is, the output port, is connected to the HDMI_IN4, that is, the No. 4 input port of the HDMI switching matrix chip, for controlling and querying the register information of the HDMI switching matrix chip, and outputting the information received by the CPU module to the HDMI switching matrix chip for external display; the PCIE3.0 (a high-speed serial computer expansion bus standard) interface of the CPU module is connected to the 5G module, that is, the CPU module can connect to the Internet through the 5G module; the RGMII (Reduced Gigabit Media Independent The CPU module can be connected to the Giga phy module through the Giga phy module. 3 in the figure is a Power power module, which can use the 3.3V output of RK809 to power the switching circuit. 4 in the figure is a WiFi module, which can use the WiFi6 module AP6275S. 5 in the figure are 2 USB interfaces, which can be 2 USB3.0 interfaces of the CPU module RK3568. Users can use this interface to perform OTA (Over-the-Air Technology) upgrades for the system where the switching circuit is located. 6 in the figure is an LCD module, i.e. a touch screen module, which can use an ultra-high-definition LCD display with integrated display and touch. 7 in the figure is an HDMI switching matrix chip, i.e. a switching matrix module, which can use the HDMI switching matrix chip GSV2008. The chip provides 4-way HDMI input cross-switching to 2-way HDMI output, that is, the content displayed to the video matrix is ​​the content of 2 HDMI channels selected from HDMI input 1, HDMI input 2, HDMI input 3, and HDMI input 4, as HDMI output 1 and HDMI output 2. 8 in the figure is a 5G module, which can use the RM500U5G module. 9 in the figure is a Giga phy module, which can use RTL8211F.

[0088] For further information, please refer to Figure 4 , Figure 4A schematic diagram of an application scenario of a video matrix switching method is provided, specifically:

[0089] The monitoring video 5, monitoring video 8 and software system are connected to the switching matrix module as wired input sources through HDMI_IN1, HDMI_IN2 and HDMI_IN3, that is, input port 1, input port 2 and input port 3, respectively, and the control host, mobile phone, and Pad (i.e., tablet computer) are used as network input sources to construct multiple input sources of the switching matrix module. Among them, the software control system is a screen running a security alarm linkage system, a fire video linkage system, a municipal control system, etc. At the same time, an event notifier of the notification software KaihongOS is running on these systems. The communication protocol of the event notifier is the control protocol of the switching circuit request switching of the KaihongOS-HDMI-4X2 HDMI remote control display switching matrix module, i.e., the video matrix.
