Fig. 5 is a flowchart illustrating a disaster recovery backup method according to an exemplary embodiment, where the method includes the following steps, as shown in fig. 5.

Step 501: and the decoding equipment sends a second registration request to the second video management server, wherein the second registration request carries the first equipment identifier of the decoding equipment.

Wherein the first device identification of the decoding device may be an index code (indexcode) of the decoding device. When the decoding device is successfully registered in the second video management server, providing a service scene for the decoding device by a second video management service in the second video manager, and executing step 502; when the decoding apparatus fails to register in the second video management server, step 504 is directly performed. And the decoding equipment sends a second registration request to the second video management server every other registration time period, and when the registration is not successful within a third specified time period, the decoding equipment determines that the second video management server has a fault and further sends a first registration request to the first video management server. In the embodiment of the present disclosure, the second registration duration and the third specified duration are not specifically limited, for example, the second registration duration may be 1s, 2s, or 3s, etc.; the third specified duration may be 5s, 6s, or 10 s.

It should be noted that, during this timing period, the decoding apparatus may continue to send the second annotation request to the second video management server every second registration duration until the third duration is reached, and when the registration in the second video management server is not successful within the third duration, it is determined that the second video management server has a fault, and step 504 is executed. Alternatively, the decoding apparatus may record the number of times of successful unregistration, and when detecting that the unregistration is successful within a first preset number, determine that the second video management server has a failure, and perform step 504 if the registration is failed. For example, the third specified duration is 6s, the decoding apparatus sends a second registration request to the second video management server every 2s, and if the decoding apparatus fails to register for 3 consecutive times, it determines that the second video management server fails, and step 504 is executed if the registration fails.

Step 502: when the decoding device successfully registers in the second video management server based on the second registration request, the decoding device detects response information between the decoding device and the second video management server, wherein the second video management server is a video management server in a video subsystem where the decoding device is located.

The response information may be a heartbeat packet in a heartbeat mechanism, and correspondingly, the decoding device may detect whether the second video management server still maintains connection with the decoding device through the heartbeat mechanism, where the heartbeat mechanism is a mechanism that sends a self-defined structure (heartbeat packet) at a fixed time to let the other party know that the other party still normally works, so as to ensure the validity of the connection. Accordingly, the step of the decoding device detecting the second video management server through the heartbeat mechanism may be: the decoding device sends a first heartbeat packet to the second video management server every other first heartbeat time length, where the first heartbeat packet is used to notify the second video management server that the decoding device is working normally and instruct the second video management server to return response information, where the first heartbeat time length may be set and changed as needed. When the heartbeat of the second video management server and the heartbeat of the decoding device are normal, the decoding device works under a service scene provided by the second management server; when the second video management server does not respond to the heartbeat mechanism, step 504 is performed.

Step 503: when the response information between the decoding device and the second video management server is not detected within a second specified time period, the decoding device determines that the second video management server is out of order.

In the embodiment of the disclosure, timing is started after the decoding device sends the response information to the second video management server, and if the decoding device does not receive the response information returned by the second video management server within the second time period, the decoding device determines that the second video management server has a fault. The second specified time length may be set and changed as needed, and in the embodiment of the present disclosure, the second specified time length is not particularly limited, for example, the second specified time length may be 30s, 45s, or 60 s.

It should be noted that, when the decoding device determines, through the heartbeat mechanism, that the operating condition of the second video management server is that, in the above timing period, the decoding device may continue to send the first heartbeat packet to the second video management server every other first heartbeat duration until the second duration is reached, and if the heartbeat message returned by the second video management server is not received within the second duration, it is determined that the second video management server has a fault. Or, the decoding device may detect the number of times that the heartbeat message returned is not received, and determine that the second video management server fails when detecting that the heartbeat message returned by the second video management server is not received within a first preset number of times. For example, the second specified duration is 30s, the decoding apparatus sends a heartbeat packet to the second video management server every 10s, and if the decoding apparatus does not receive a heartbeat message returned by the second video management server for 3 consecutive times, it determines that the second video management server has a fault.

And when response information between the decoding equipment and the second video management server is detected within a second specified time, the decoding equipment determines that the second video management server is normal. And operates under the service provided by the second video management server and continues to detect the response information between the decoding apparatus and the second video management server.

Step 504: when the decoding device fails to register in the second video management server or the second video management server fails based on the second registration request, the decoding device sends a first registration request to a first video management server in the video monitoring system, wherein the first registration request is used for requesting that a service scene provided by the first video management server is configured with a service scene the same as that of the second video management server.

The first management server is provided with a first video management service, the second management server is provided with a second video management service, and the second video management server is a video management server in a video monitoring subsystem where the decoding equipment is located. The first registration request carries a first device identifier of the decoding device. When the decoding equipment detects that the second video management server has a fault, the decoding equipment sends a first registration request to a first video management server in the video monitoring system. Wherein the decoding apparatus detecting that the second video management server has failed includes: and detecting that the second video management server can not work normally through the response information, or sending a second registration request to the second video management server without receiving the second registration request and successfully registering in the second video management server.

Accordingly, the step of the decoding apparatus detecting whether the second video management server is operating normally through the response information can be implemented through step 501 and step 502. The method for the decoding device to detect whether the second video management server is working normally by sending the second registration request to the second video management server may be: and the decoding equipment sends a second registration request to the second video management server every second registration time length, and when the registration agreement message is not received within a third specified time length, the decoding equipment determines that the second video management server has a fault and further sends a first registration request to the first video management server. In the embodiment of the present disclosure, the second registration duration and the third specified duration are not specifically limited, for example, the second registration duration may be 1s, 2s, or 3s, and the like; the third specified duration may be 5s, 6s, or 10 s.

It should be noted that, during this timing period, the decoding device may continue to send the second annotation request to the second video management server every second registration duration until the third duration is reached, and if the second annotation request is not successfully registered within the third duration, it is determined that the second video management server fails. Alternatively, the decoding apparatus may detect the number of times of the success of the unregistration, and determine that the second video management server has a failure when the success of the unregistration within a second preset number of times is detected. For example, the third specified duration is 6s, the decoding apparatus sends a second registration request to the second video management server every 2s, and if the decoding apparatus does not register successfully for 3 consecutive times, it determines that the second video management server has a fault.

Step 505: the first video management server receives a first registration request sent by decoding equipment in the video monitoring system.

In a possible implementation manner, after receiving a first registration request sent by the decoding device, the first video management server directly receives the registration request of the decoding device and provides a service for the decoding device; in another possible implementation manner, after receiving the first registration request sent by the decoding device, the first video management server executes step 506, and determines whether the service of the second video management server corresponding to the decoding device is normal.

Step 506: and the first video management server determines the working state of a second video management server in the video monitoring subsystem where the decoding equipment is positioned.

The decoding device stores the address of a first video management server and the address of a second video management server, and when the first video management server receives a first registration request of the decoding device, the second video management server corresponding to the decoding device is determined according to a first device identifier of the decoding device in the first registration request.

In a possible implementation manner, a first video management server stores a corresponding relationship between a first device identifier of the decoding device and an address of a second video management server in a system in which the decoding device is located, the first video management server determines the first device identifier in the first registration request, and determines an address of the second video management server corresponding to the first device identifier according to the corresponding relationship between the first device identifier and the address.

In another possible implementation manner, the first video management server stores a corresponding relationship between a subsystem identifier of a video monitoring subsystem where the decoding device is located and the first device identifier, determines the first device identifier in the first registration request, determines the subsystem identifier of the video monitoring subsystem, and determines the address of the second video management server in the video monitoring subsystem according to the subsystem identifier.

In another possible implementation manner, when the decoding device is successfully registered, the decoding device stores the address of the second video management server, and the first video management server sends an acquisition request to the decoding device, where the acquisition request carries the server identifier of the first video management server; and the decoding equipment sends the address of the second video management server stored by the decoding equipment to the first video management server according to the server identification of the first video management server.

In a possible implementation manner, the first video management server may always detect whether a second video management server in the video monitoring system has a fault in the video monitoring system; in another possible implementation manner, the first video management server detects whether the second video management server fails or not when receiving the first registration request sent by the decoding device.

The first video management server may further include an SIP service, and accordingly, the first video management server may detect whether a second video management server in the second video management server is normal through the SIP service, where the process may be implemented through the following steps (1) to (3), and includes:

(1) and the first video management server determines the video monitoring subsystem where the decoding device is located through the first device identification of the decoding device.

The first video management server may determine the first device identification of the decoding device through the first registration request. The decoding device may store an address of the first video management server and an address of the second video management server, and when the first video management server determines the first device identifier of the decoding device, the first device identifier may be used to obtain the address of the second video management server in the decoding device.

(2) And the first video management server detects the response information of the second video management server under the video monitoring subsystem through the SIP service.

And (3) the first video management server detects response information of the second video management server through the SIP service according to the address of the second video management server in the step (1).

(3) And when the response information of the second video management server is detected within the first specified time, the first video management server determines that the second video management server works normally.

And when the first video management server detects that a second video management server in the video monitoring subsystem where the decoding equipment is positioned is normal, discarding the first registration request.

Correspondingly, when the decoding device is not successfully registered in the first video management server, the decoding device determines that the second video management server is recovered to be normal, and sends a second registration request to the second video management server.

The step of sending the second registration request to the second video management server by the decoding device without successfully registering in the first video management server is similar to the step of sending the second registration request to the second video management server by the decoding device in step 503, and details are not repeated here.

It should be noted that, after receiving the registration request, the video management server may first detect whether the decoding device corresponding to the registration request is at the same level as the video management server. If the decoding device and the video management server are in the same level, the video management server is indicated to be a second video management server; if the video management server is not at the same level as the decoding apparatus, it indicates that the video management server is the first video management server, step 506 is executed to detect the response information between the second video management server and the first video management server.

When the response information between the second video management server and the first video management server is not detected within a first specified time, the first video management server determines that the second video management server is out of order.

The first specified duration may be set and changed as needed, and the first specified duration may be the same as the second specified duration and the third specified duration, or may be different from the second specified duration or the third specified duration. In the disclosed embodiment, the first specified time period is not particularly limited, and for example, the first specified time period may be 30s, 45s, or 60 s.

The step in which the first video management server determines that the service of the second video management server has a fault in this step is similar to the step of detecting whether the service of the second video management server is normal in step 501-502, and is not described herein again.

Step 507: and when the second video management server has a fault, the first video management server acquires the first service data of the second video management server from the data platform according to the first registration request.

Before the step, the control equipment sends a video on-wall instruction to a second video management server; the second video management server receives the video on-wall instruction and generates first service data according to the instruction; the second video management server acquires the first service data and transmits the first service data to a data platform. Wherein the first service data includes: a first device identification of the decoding device, a second device identification of the designated monitoring device, a third device identification of the display device, and the like. And the data platform is a data platform in the video monitoring subsystem where the second video management server is located, and can also be a general data platform in the video monitoring system.

And the first video management server determines a data interface corresponding to the decoding device according to the first device identifier in the first registration request, and calls the first service data through the data interface. The process can be realized by the following steps (1) to (3), including:

(1) the first video management server determines a first device identification of the decoding device according to the first registration request.

(2) And the first video management server calls a data interface corresponding to the first equipment identifier in the data platform through the first equipment identifier.

(3) The first video management server acquires the first service data through the data interface.

It should be noted that each time the second video management server acquires the first service data, the second video management server transmits the first service data to the data platform. The data platform may store the first service data and a time at which the first service data was received in the data platform every time the first service data is received; the data platform may further store the first service data in an overlay manner every time the first service data is received, that is, only the first service data that is modified last time is stored in the data platform.

Correspondingly, when the first video management server calls the first service data from the data platform, only the first service data which is modified last time can be called, and a plurality of groups of first service data can also be called.

Step 508: and the first video management server configures the service scene provided by the first video management server with the same service scene as the second video management server according to the first service data.

After the first video management server acquires the first service data, a service scene is provided for the decoding device according to the first service data, so that the decoding device can still perform video decoding and other work according to the current correct service data after the second video management server fails. For example, the service scenario provided by the second video management server is: and the decoding equipment corresponding to the first equipment identifier acquires the video stream of the first appointed monitoring equipment corresponding to the second equipment identifier, and displays the video stream on the first window of the first display equipment corresponding to the third equipment identifier. After the first video management server acquires the first service data, configuring a service scene as: and the decoding equipment corresponding to the first equipment identifier acquires the video stream of the first appointed monitoring equipment corresponding to the second equipment identifier, and displays the video stream on a first window of the first display equipment corresponding to the third equipment identifier.

Step 509: the first video management server provides the service for the decoding device through the service scenario.

In this step, the process of the first video management server providing a service to the decoding device according to the configured service scenario may be: the first video management server sends a video on-wall instruction to the decoding device through the service scene, wherein the video on-wall instruction carries a second device identifier of the designated monitoring device in the video monitoring subsystem and a third device identifier of the display device, and instructs the decoding device to decode the video stream acquired by the designated monitoring device to obtain video data, and the video data is rendered in the display device to obtain a video picture.

Accordingly, the process of the decoding device continuing to operate in the service scenario may be:

511A: the decoding device receives a video on-wall instruction sent by the first video management server, wherein the video on-wall instruction carries a second device identifier of the designated monitoring device in the video monitoring subsystem and a third device identifier of the display device;

511B: the decoding equipment acquires the video stream acquired by the appointed monitoring equipment according to the second equipment identifier;

511C: decoding the video stream by the decoding equipment to obtain video data;

511D: and rendering the video data in the display equipment by the decoding equipment according to the third equipment identification to obtain a video picture.

It should be noted that, in the process of providing a service for the decoding device, the first video management server may receive a new video on-wall instruction, and when the first video management server receives the new video on-wall instruction, modify the service data according to the new video on-wall instruction to obtain second service data, and upload the second service data to the data platform, so that when the second video management server recovers to normal, the second service data may also be used to provide a service scene for the decoding device. The process may be:

the first video management server acquires second service data for providing services for the decoding device; and sending the second service data to the data platform, wherein the second service data is used for configuring the same service scene as the first video management server in the second video management server when the second video management server is recovered to be normal.

Another point to be noted is that, in a possible implementation manner, after the first video management server provides a service for the decoding device, the first video management server may provide a service for the decoding device all the time until the first video management server goes wrong, or until the user switches the video management server of the decoding device to another video management server; in another possible implementation manner, the first video management server may detect whether the second video management server returns to normal while providing a service for the decoding device, and when it is detected that the second video management server returns to normal, automatically disconnect the decoding device, and when the decoding device cannot communicate with the first video management server, send a third registration request to the second video management server. The corresponding step can be realized by the following steps:

(1) and when the first video management server detects that the second video management server returns to normal, stopping providing the service for the decoding device.

(2) When the first video management server stops providing service for the decoding device, the decoding device determines that the second video management server is recovered to be normal.

(3) The decoding device sends a third registration request to the second video management server, wherein the third registration request is used for instructing the second video management server to provide the service for the decoding device.

(4) The decoding apparatus continues to operate in a service scenario provided by the second video management server.

Further, when the first video management server receives a new video on-wall instruction, the first service data is modified according to the new video on-wall instruction to obtain second service data, and the second service data is uploaded to the data platform, so that a service scene can be configured according to the second service data when the second video management server is recovered to be normal subsequently, and a service scene can be configured for the decoding device according to the service data in the data platform when the first video management server is offline from the second video management server.

Furthermore, the first video management server can detect whether the second video management server is normal, the first video management server agrees to register the decoding device when the second video management server is abnormal, and the first video management server can automatically disconnect the decoding device after the second video management server is recovered to be normal, so that resources of the video management server can be fully utilized.
