All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
At present, the existing distributed signal transmission system only has one management node and cannot be switched, and if the management node is disconnected, the whole signal transmission system is paralyzed and cannot be controlled. Based on this, the embodiment of the invention provides a management node switching method, a management node switching device, a management node switching signal transmission system and electronic equipment, and the technology is applied to the field of audio and video signal transmission, and particularly relates to an audio and video signal transmission system which does not affect global operation due to single-point failure.
To facilitate understanding of the embodiment, a detailed description is first given of a management node switching method disclosed in the embodiment of the present invention.
Example 1
The embodiment of the invention provides a management node switching method, which is applied to a signal transmission system, wherein the signal transmission system comprises a plurality of nodes. The signal transmission system refers to a system for transmitting signals, and the signal transmission system in this embodiment may be an audio/video signal transmission system, that is, signals transmitted in the signal transmission system are audio signals and video signals. A signal transmission system needs to include a plurality of nodes, which are the start point and the end point of transmission signals, i.e., nodes can transmit signals to be transmitted to other nodes. The device performing the method in this embodiment may be an audio video processing device.
Based on the above description, referring to the flowchart of a management node switching method shown in fig. 1, the management node switching method includes the following steps:
step S102, one node is selected from the nodes to be used as a management node, and the management node is used for managing the signal transmission system.
The management node is used for managing the signal transmission system, namely managing the nodes of the signal transmission system so as to realize corresponding functions, for example, the management node can manage the functions of audio/video switching, large screen windowing, seat management and the like of the signal transmission system, and the audio/video switching is how to switch audio and video; the large-screen windowing is to play audio and video on a large screen, perform audio and video splicing processing and the like, for example, play the video on the large screen; the agent management refers to the management of agents formed by a plurality of computer clients; the seat refers to a unit of a control room, and refers to personnel, a seat station and office tools (a mouse keyboard, a display terminal and the like), and common office scenes include a customer service center, a command center, a dispatching center, a data center, a monitoring center and the like.
It should be noted that, in the signal transmission system, it may be selected as a management node, that is, the node may be a node that transmits a signal or a node that receives a signal, and may be used as a management node.
Step S104, the management node executes the following message sending operation: the management node sends a first message based on a preset time interval; the first message includes address information of a node of the signaling system.
The management node needs to perform a message sending operation, that is, send a first message (the first message may also be referred to as an alive message) to other nodes except the management node, where the sending interval time of the first message is fixed and may be 1-2 s. The first message includes addresses of all nodes of the signal transmission system, for example: assuming that the signal transmission system includes 4 nodes, where a first node is a management node, the first node needs to send a first message to three other nodes at regular intervals, where the first message includes: the addresses of these 4 nodes.
And step S106, monitoring the first message by the nodes except the management node.
After the management node sends the first message, other nodes except the management node monitor the first message, that is, the other nodes except the management node can receive the first message once every a period of time, and if the first message is not received for a long time, the problem of communication of the management node is shown.
Step S108, if the time from the current time to the time that the nodes except the management node receive the last first message is larger than the preset time threshold, selecting one node from the nodes except the management node as the management node, and continuing to execute the message sending operation.
If the time from the current time to the previous first packet received by the nodes except the management node is greater than the preset time threshold (the time threshold here may be 3 times of the first packet transmission interval), it indicates that the other nodes except the management node do not receive the first packet for a long time, and then the management node is likely to have a communication problem.
It should be noted that, after determining the new management node, if the communication of the old management node is recovered to normal, the old management node does not execute the function of the management node any more, and does not send the first message; instead, the new management node performs the function of the management node and sends the first packet.
In the management node switching method provided by the embodiment of the invention, a management node sends a first message, and nodes except the management node monitor the first message; and if the time from the current time to the time when the nodes except the management node receive the last first message is larger than a preset time threshold, selecting one node from the nodes except the management node as the management node. In the mode, one node can be selected from the nodes except the management node as the management node when the management node is disconnected, so that the management node is switched, and the running stability of the signal transmission system is improved.
Example 2
The embodiment of the invention also provides another management node switching method; the method is realized on the basis of the method of the embodiment; the method mainly describes a specific implementation mode of selecting one node from the nodes as a management node.
As shown in fig. 2, another management node switching method is a flowchart, and the management node switching method includes the following steps:
in step S202, the nodes are numbered in advance, and the nodes are selected as management nodes based on the numbers.
The nodes of the signal transmission system in this embodiment include at least one transmitting node and at least one receiving node. The transmitting node is used for transmitting signals, and the receiving node is used for receiving signals. The transmitting node can be an input end box, and the input end box is used for encoding the audio and video and transmitting the encoded audio and video; the receiving node can be an output terminal box, the output terminal box is a box for outputting after audio and video processing, and the function is to process the received audio and video, such as decoding and the like.
All nodes of the signal transmission system are numbered in advance, and a sending node and a node are not divided, for example: the signal transmission system has two transmitting nodes and two receiving nodes, which may be numbered 1, 2, 3, 4, respectively.
For example, the client software numbers the sending-end box and the receiving-end box in sequence, transmits the number information to the switch through the network, and the switch inputs the number information to the sending-end box and the receiving-end box.
Based on the numbers, the node is selected as the management node, the node with the smallest number may be selected as the management node, and the node with the largest number may also be selected as the management node, for example: the node with the smallest number is selected as the management node, and the node with the number 1 is used as the management node.
For example, the client software designates a box with the minimum number as a management node through a network and a switch, and the box with the function of the management node regularly sends an online (i.e., normally working) data message to the network in a multicast manner, wherein the frequency is once per second, the data message is named as an alive message, and the alive message contains the number of the box and IP (internet protocol) address information.
In addition to selecting a node as a management node based on the number, the node may be designated by a user as a management node by: receiving a management node selection instruction sent by a user; and selecting the node corresponding to the management node selection instruction as the management node. The user firstly sends a management node selection instruction to the client, and the node with the corresponding number or the corresponding address can be selected as the management node according to the management node selection instruction.
For example, after the system is built, the client and all node boxes are connected, the client designates any online input end and receiving end box as a management node box through a network and a switch, the management node box sends an alive message to the network, other boxes monitor the alive message and receive the control of the management node box, meanwhile, client software also monitors the alive message to ensure the normal operation of the whole system, and if other boxes or client software cannot receive the alive message for 3 times continuously, the client designates the management node again.
Step S204, the management node executes the following message sending operation: the management node sends a first message based on a preset time interval; the first message includes address information of a node of the signaling system.
If the nodes are numbered in advance, the first message sent includes the address information of the nodes of the signal transmission system, and also includes the numbers corresponding to all the nodes. For example: node 1, address xxx; node 2, address xxx … …, and so on.
In step S206, the nodes except the management node monitor the first packet.
All sending end boxes and receiving end boxes are added with multicast taking a box with a function of managing nodes as a sending unit, and an alive message is monitored and controlled by the box with the function of managing nodes. And the software client monitors the alive message, so that the box control system with the function of managing the node is ensured, the software client can be closed, and the closing and the opening of the software client do not influence the management control function of the management node box on the system.
Step S208, if the time from the current time to the time when the nodes except the management node receive the last first message is larger than the preset time threshold, selecting one node from the nodes except the management node as the management node, and continuing to execute the message sending operation.
When other boxes or client software cannot receive an alive message for a long time, the management node is determined to be offline, the box with the minimum number in the online state boxes is automatically converted into the management node, information and the serial number of the last control node are recorded, and message sending operation is continuously executed.
If the off-line management node is on-line again, the management right can not be preempted, namely if the off-line management node is on-line again, the current management node continues to execute the message sending operation.
When the offline box is online again, the offline box does not seize the management right, the offline box does not send an alive message, and the current box (namely the box reselected after the offline box) continues to send the alive message. Only when the box with the function of managing the nodes is disconnected, the box with the minimum number can be automatically converted into the managing nodes.
When the system is large and the boxes of the sending end and the receiving end are large, we select the multi-node control mode, need to group the nodes, and execute through step a 1-step a 2:
step A1, if the number of nodes is larger than the preset number threshold, the nodes are grouped, wherein the number of nodes in each group is smaller than the number threshold.
All nodes are divided into a plurality of groups, and the number of stages of each group is smaller than a preset number threshold value. The client sequentially numbers the sending end boxes and the receiving end boxes of each group, the number information is transmitted to the switch through the network, and the switch inputs the number information to the sending end boxes and the receiving end boxes.
Step a2, for each group of nodes, performs the step of selecting one of the nodes as the management node.
Selecting a management node for a group independently, for example, grouping all the sending end boxes and all the receiving end boxes by client software, for example, 1 to n are a group, n +1 to m + n are a group, and so on; the client software appoints the box with the minimum number in each group as a management node through a network and a switch, and sends the same control command to all the appointed management nodes; the working steps in all the groups are as in steps S202-S208, and are not described in detail here. The normal work of other groups is not influenced by the disconnection, conversion and restarting of the control node box in one group.
The technical scheme is illustrated in a single control node mode without grouping: the method comprises the steps that two sending end boxes and two receiving end boxes are arranged in a building system, the sending end boxes and the receiving end boxes are sequentially numbered as 1, 2, 3 and 4, after power is on, client software designates the box numbered as 1 as a management node, an alive message is sent to a network, the boxes numbered as 2, 3 and 4 monitor the alive message, the control of the box numbered as 1 is received, the system normally works, meanwhile, the client software also monitors the alive message, and the working state of the management node is tracked.
When the boxes with the numbers of 2, 3 and 4 do not receive the alive messages sent by the management node box 1 for 3 times continuously, the box with the number of 2 is automatically converted into the management node box, meanwhile, the information and the serial number of the box with the number of 1 are recorded, the alive messages are sent to the network in a multicast mode, and the boxes with the numbers of 3 and 4 receive the control of the box with the number of 2.
When the box numbered 1 returns to normal, the box numbered 1 does not send an alive message to the network in the system but receives the control of the box numbered 2. The function is to ensure that the management box is not influenced by the recovery of the previous management box when working normally; when the box with the number of 2 is disconnected and loses connection, the box with the number of 1 is converted into a management node box again to send an alive message to the network, and the management system works normally.
According to the method provided by the embodiment of the invention, the management node is not fixed, and the management node can be selected according to the control of the client to control the whole audio and video transmission system. Any box of the signal transmission system can be used as a management node, and the control of the whole system is not influenced when any box is damaged. For the input and output functions, because the input and output functions are connected with each other through a network, the short circuit of a single box does not influence the normal work of other boxes.
