In the embodiment of the present invention, the application scenario is a main/standby terminal switching system, and the application scenario includes a server, at least two terminals, a main/standby signal controller, and a display device, where the at least two terminals include a main terminal and a standby terminal, and it should be noted that the terminals may also include other terminals besides the main terminal and the standby terminal, for example, a non-main/standby terminal. Fig. 1 exemplarily shows a server 10, an active terminal 20A, a standby terminal 20B, an inactive terminal 20C, an active/standby signal controller 30, and a display device 40. The active terminal 20A and the standby terminal 20B are connected through an active/standby signal controller 30, the active/standby signal controller 30 is connected with the display device 40, and the active terminal 20A, the standby terminal 20B, and the inactive/standby terminal 20C are connected to the server 10 through network communication, for example: the server 10 is connected to the Mobile communication network by communication in a local area network, a wide area network, a wireless network, a global system for Mobile communication (GSM), a third generation Mobile communication network, a fourth generation Mobile communication network, a fifth generation Mobile communication network, or the like.
The active-standby signal controller 30 is configured to receive an input signal, copy the input signal into two paths of signals, and send the two paths of signals to the active terminal 20A and the standby terminal 20B, respectively, the active-standby signal controller 30 is further configured to receive a control signal sent by the active terminal 20A, and take an output signal of the active terminal 20A as an output according to the control signal, and the active-standby signal controller is further configured to receive an output signal sent by the active terminal 20A, and send the output signal to the display device 40.

In a practical application environment, there may be one or more input signals and output signals, or there may be no input signal, only an output signal, etc.
The at least two terminals may be, for example, a tablet computer, a personal computer, a laptop computer, and the like with video functions. The server may be a server, such as a rack server, a blade server, a tower server, or a rack server, or may be a server cluster composed of a plurality of servers, or a cloud computing service center. The display device may be a TV, a projector, or a stereo.
It should be noted that the method provided by the embodiment of the present application may be further extended to other suitable application environments, and is not limited to the application environment shown in fig. 1. In practical applications, the application environment may also include more or fewer terminals and servers.
As shown in fig. 2, an embodiment of the present invention further provides a method for switching between a master terminal and a standby terminal, where the method is applied to a server, and the method includes:
In the embodiment of the present invention, the service request instruction may be initiated by the master terminal or initiated by other terminals. Specifically, when the main terminal serves as a service initiator, the server receives a service request instruction initiated by the main terminal. Or, when the main terminal and the standby terminal are used as service participants, the other terminals send service request instructions to the server, and the server receives the service request instructions sent by the other terminals.
And 204, establishing service connection with the main terminal according to the service request instruction.
When the initiator of the service request instruction is the main terminal, the server establishes service connection with the main terminal according to the received service request instruction, and the service connection is established in advance, so that the service data transmission efficiency is improved. It can be understood that, in some other embodiments, when the initiator of the service request instruction is another terminal, after receiving the service request instruction sent by the other terminal, the server sends the service request instruction to the active terminal and the standby terminal respectively, and establishes service connections with the active terminal and the standby terminal respectively.
After the service connection is established between the main terminal and the server, the server sends a service request instruction sent by the main terminal to the standby terminal, and establishes the service connection with the standby terminal. The service request instruction sent by the server to the standby terminal is the same as the service request instruction sent by the main terminal to the server.
And 208, receiving the heartbeat message sent by the master terminal.
In the embodiment of the present invention, the format and the content of the heartbeat message may be set according to a specific application scenario, for example, the heartbeat message may carry an identity of a master terminal that sends the heartbeat message, and the server receives the heartbeat message sent by the master terminal and determines the master terminal that sends the heartbeat message through the identity. The identity can be characterized by the network protocol address of the primary terminal or by the media access address.
The server can determine whether the main terminal is in a fault state based on the heartbeat message, wherein the fault state can be that the main terminal fails in hardware or software, so that service data output cannot be normally performed. The whole fault detection and switching process of the main terminal and the standby terminal is in the second level, so that a user cannot feel that the terminals are switched, and the service availability is improved.
In the embodiment of the invention, the server establishes service connection with the main terminal according to the service request instruction by receiving the service request instruction, then sends the service request instruction to the standby terminal and establishes service connection with the standby terminal, then receives heartbeat messages sent by the main terminal, determines whether the main terminal is in a fault state or not based on the heartbeat messages, and if so, takes the standby terminal as the main terminal, thereby improving the service reliability.
In some embodiments, the determining whether the active terminal is in a failure state based on the heartbeat message includes: and if the heartbeat message sent by the main terminal is not received within a preset time period, determining that the main terminal is in a fault state.
In the embodiment of the present invention, for example, it is assumed that the active terminal is preset to send a heartbeat message to the server every 3 seconds, and if the server does not receive the heartbeat message sent by the active terminal within 9 seconds, it may be considered that the active terminal is currently in a fault state. It can be understood that, in some other embodiments, the server and the primary terminal maintain normal heartbeat, at this time, the heartbeat message carries a fault state of the primary terminal, and if the heartbeat message sent by the primary terminal indicates that the camera thereof is unavailable, the server determines that the primary terminal is currently in the fault state, and prepares to initiate primary-secondary switching. Meanwhile, the fault terminal can prompt a user to troubleshoot faults through the indicator lamp and the operation page, and the server informs the user through the operation page to remind the user to troubleshoot faults. It should be noted that the time when the terminal sends the heartbeat to the server, that is, the preset value, is preset and is fixed.
In some embodiments, as shown in fig. 3, the active terminal and the standby terminal are connected through an active/standby signal controller; if the main terminal is in a fault state, taking the standby terminal as the main terminal, including:
When the server detects that the main terminal is in the fault state based on the heartbeat message, the server records the fault state of the main terminal and disconnects the service connection with the main terminal in the fault state, thereby being beneficial to providing a service channel for the data output of a subsequent standby terminal.
And after the server disconnects the service connection with the main terminal in the fault state, the server outputs the data of the standby terminal to the service. Specifically, the server sends a standby main instruction to the standby terminal, and when the standby terminal receives the standby main instruction, the server outputs a control signal to the main/standby signal controller to control the main/standby signal controller to output the output signal of the standby terminal.
After the server sends a standby raising main instruction to the standby terminal, on one hand, the standby terminal outputs a control signal to the main and standby signal controllers according to the standby raising main instruction, on the other hand, the standby terminal feeds back a standby raising main response message to the server, and after the server receives the standby raising main response message returned by the standby terminal, the standby terminal is set as a main terminal according to the standby raising main message, so that the switching of the main and standby terminals is realized, and the whole fault detection and switching process is in the second level, so that the availability of terminal services is improved.
In some embodiments, as shown in fig. 4, before the receiving the service request instruction, the method further includes:
The hot standby relation refers to that two devices are mutually backed up and jointly execute the same service. When one device fails, the other device undertakes the service task, and the system can be ensured to continuously provide services without manual intervention. Specifically, the two terminals are preset to be in a hot standby relationship through a maintenance interface of the server, and the two terminals in the hot standby relationship each other join the service at the same time.
After the terminal is started, a main/standby query request message is sent to the server, and after the server receives the main/standby query request messages sent by at least two terminals, the server sets the at least two terminals as a main terminal and a standby terminal according to a competition principle. Specifically, the server sends the priority of the master/slave query request message according to the at least two terminals, that is, the terminal that requests first is the master terminal, and the terminal that requests later is the slave terminal. It can be understood that the server may also set a terminal without a primary-secondary relationship as an inactive terminal.
In some embodiments, as shown in fig. 5, the method further comprises:
When the fault of the main terminal is recovered, the main state and the standby state are requested to the server again, and the server receives a main state and standby state request instruction sent by the main terminal.
When the primary terminal fails, the standby terminal is already used as the current primary terminal, so that when the server receives a primary/standby state request instruction sent by the primary terminal after the failure is recovered, the primary terminal can only be set as standby, and the primary/standby state is sent to the primary terminal to inform the primary terminal that the primary terminal is currently used as the standby state. The active/standby state includes an active state, a standby state, and an inactive/standby state. The state may be identified by a state identifier, and when the state identifier is a first identifier, the state identifier indicates a primary state, when the state identifier is a second identifier, the state identifier indicates a standby state, and when the state identifier is a third identifier, the state identifier indicates an inactive state. The first flag of the state may be 1, the second flag may be 2, and the third flag may be 3. The first flag of the state may be 0, the second flag may be 1, and the third flag may be 2, which is only an example and is not a limitation thereto.
And after setting the main terminal after the fault recovery as a standby state, the server sends a service request instruction to the main terminal in the standby state, establishes service connection with the main terminal in the standby state, and recovers to a state that the main terminal and the standby terminal work simultaneously. It should be noted that when the two terminals operate simultaneously, that is, the two terminals join in the service simultaneously, only the main terminal can output the audio and video data, and the standby terminal only joins in the service and does not output the audio and video data.
To facilitate an understanding of the invention, the following examples are given:
referring to fig. 6, two terminals are preset to be in a hot standby relationship through a maintenance interface of the server, and two terminals in the hot standby relationship each other join in a service at the same time. After the terminal is started, a main/standby query request message is sent to the server, and after the server receives the main/standby query request messages sent by at least two terminals, the server sets the at least two terminals as a main terminal and a standby terminal according to a competition principle. Specifically, the server sends the priority of the master/slave query request message according to the at least two terminals, that is, the terminal that requests first is the master terminal, and the terminal that requests later is the slave terminal.
And then, the server receives a service request instruction initiated by the main terminal, and establishes service connection with the main terminal according to the service request instruction. And the server sends the service request instruction sent by the main terminal to the standby terminal and establishes the service connection with the standby terminal. The server receives heartbeat messages sent by the main terminal, determines whether the main terminal is in a fault state or not based on the heartbeat messages, specifically, if the main terminal is preset to send the heartbeat messages to the server every 3 seconds, if the server does not receive the heartbeat messages sent by the main terminal within 9 seconds, the main terminal can be considered to be in the fault state currently, or the server and the main terminal keep normal heartbeat, at the moment, the heartbeat messages carry the fault state of the main terminal, and if the heartbeat messages sent by the main terminal indicate that a camera of the main terminal is unavailable, the server determines that the main terminal is in the fault state currently. The fault state may be that the main terminal hardware fails or the software fails, which results in that the service data output cannot be performed normally, and when the main terminal is in the fault state, the audio/video service data output is interrupted, and at this time, the server determines that the main terminal is unavailable.
Then, the server records the fault state of the main terminal, and disconnects the service connection with the main terminal in the fault state, the server sends a standby raising main instruction to the standby terminal, when the standby terminal receives the standby raising main instruction, a control signal is output to a main and standby signal controller, the main and standby signal controller is controlled to output the output signal of the standby terminal, meanwhile, the standby terminal feeds back a standby raising main response message to the server, and after the server receives the standby raising main response message returned by the standby terminal, the standby terminal is set as the main terminal according to the standby raising main message, so that the switching of the main and standby terminals is realized, and the whole fault detection and switching process is second level, thereby improving the availability of terminal services. Meanwhile, the fault terminal can prompt a user to troubleshoot faults through the indicator lamp and the operation page, and the server informs the user through the operation page to remind the user to troubleshoot faults.
Then, after the fault of the primary terminal is recovered, the primary and secondary states are requested from the server again, the server receives a primary and secondary state request instruction sent by the primary terminal, and the primary terminal is used as the current primary terminal when the fault of the primary terminal occurs. The active/standby state includes an active state, a standby state, and an inactive/standby state. And after setting the main terminal after the fault recovery as a standby state, the server sends a service request instruction to the main terminal in the standby state, establishes service connection with the main terminal in the standby state, and recovers to a state that the main terminal and the standby terminal work simultaneously.
Correspondingly, an embodiment of the present invention further provides a device 700 for switching between an active terminal and a standby terminal, where the device is used for a server, and as shown in fig. 7, the device includes:
