Detailed Description

To facilitate an understanding of the invention, the invention will now be described more fully with reference to the accompanying drawings. Several embodiments of the invention are presented in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

The client 11 is used for initiating or stopping video access, the client 11 is client software which provides services such as logging in a monitoring platform, querying an equipment list, starting or stopping video access and the like for a user, the client 11 can be connected with the monitoring platform through a user network, and the network can be the internet or a local area network.

Referring to fig. 2 to 3, a video access method according to a first embodiment of the present invention is shown, including steps S01 to S10.

And step S01, the client sends a video access request to the access balancing server.

In specific implementation, a user can open client software and start the service of logging in the monitoring platform, and at the moment, the client automatically sends a video access request to the access balancing server.

The monitoring platform provides service address information accessed by the Internet in a DR mode by accessing the balance server and providing a virtual IP mode.

And S02, the access balancing server schedules an access server and forwards the video access request to the scheduled current access server.

It is understood that a scheduling policy may be preset to the access balancing server, so that the access balancing server schedules the idle, relatively idle, or newly added access server according to the scheduling policy.

When the access equilibrium server schedules the access server, the scheduled access server responds to the scheduling of the access equilibrium server.

And S03, the current access server authenticates the login of the client and then sends a real-time video request to a central balance server.

It should be noted that when the access balancing server schedules an access server to respond to a video access request, the client will log in to the monitoring platform through the scheduled current access server. Therefore, the current access server needs to authenticate the client (for example, verify the correctness of the IP and the password) to verify whether the user has the right to access the system, and after the authentication is successful, the client logs in the monitoring platform successfully through the current access server.

And S04, the central balance server schedules a central server and forwards the real-time video request to the scheduled current central server.

It is understood that a scheduling policy may be preset to the central equilibrium server, so that the access equilibrium server schedules the idle, relatively idle or newly added central server according to the scheduling policy.

Wherein, when the central equalization server schedules the central server, the scheduled central server will respond to the scheduling of the central equalization server.

And step S05, the current central server schedules a stream server and acquires a stream receiving address of the scheduled current stream server.

It should be noted that the streaming address is a sending address of the subsequent real-time video stream, and there is a difference in the streaming addresses of each streaming server.

Wherein, when the central server schedules the streaming server, the scheduled streaming server will respond to the scheduling of the central server.

It is understood that a scheduling policy may be preset to the central server, so that the central server schedules idle, relatively idle or newly added streaming servers according to the scheduling policy.

And S06, the current central server sends an instruction for pushing a real-time video stream to the current streaming server to the equipment access gateway, wherein the real-time video stream is shot by the monitoring equipment, and the instruction comprises the streaming receiving address.

And step S07, after receiving the instruction, the equipment access gateway establishes connection to the current streaming server according to the streaming receiving address and sends a request for pushing a real-time video to the monitoring equipment.

It should be noted that, since the instruction includes the stream receiving address, the stream server receiving the video stream, that is, the current stream server, can be determined according to the stream receiving address.

It can be understood that when the monitoring device receives a request for pushing a real-time video, the video obtained by shooting is sent to the device access gateway in real time.

And step S08, when receiving the real-time video stream pushed by the monitoring equipment, the equipment access gateway forwards the real-time video stream to the current stream server, and returns the execution result of the instruction to the current central server.

And step S09, when detecting that the equipment access gateway successfully pushes the real-time video stream to the current stream server, the current central server responds the stream receiving address to the client through the current access server.

It should be noted that, if the device access gateway successfully pushes the real-time video stream to the current stream server, the device access gateway returns the execution result of the normal response to the current central server, otherwise, the device access gateway returns the execution result of the abnormal response to the current central server.

And step S10, the client acquires the real-time video stream from the current stream server according to the stream receiving address.

It should be noted that, after receiving the streaming address, the client assembles an RTSP address according to a preset rule, and connects to the current streaming server through an RTSP protocol to obtain real-time video data from the current streaming server, and after successful obtaining, the client decodes and plays the real-time video data to complete real-time video detection of the user.

In summary, in the video access method in the above embodiment of the present invention, an access server is dynamically allocated to each client requiring to log in to a monitoring platform through an access balancing service, so as to achieve capacity expansion of concurrent access of massive users, and enable the login of massive users, and ensure that a high concurrent request service is provided for the users, in addition, through scheduling of the central balancing service and the central server, a video access request of each client can be responded in the respectively scheduled central server, and a real-time video stream pushed by a device access gateway can be received in the respectively scheduled stream servers, so that each client can obtain the real-time video stream in the respectively scheduled stream servers, and responses of the entire video access request are not interfered with each other, and in addition, a module of a real-time video access service is split through a reasonable architecture, and through reasonable scheduling configuration, high availability of the video access service is improved. Therefore, the video access method can meet the video access requirements of massive users, can meet the video access request of each user when meeting the high concurrency and high availability requirements on video access brought by the massive users, is not easy to have the phenomena of incapability of access, running system, queuing access and the like, and has good experience.

Referring to fig. 4 to 5, a video access method according to a second embodiment of the present invention is shown, including steps S11 to S25.

And step S11, the client sends a video access request to the access balancing server.

And step S12, the access balancing server schedules an access server according to a scheduling strategy and forwards the video access request to the scheduled current access server.

And S13, the current access server authenticates the login of the client and then sends a real-time video request to a central balance server.

And S14, the central balance server schedules a central server according to a scheduling strategy and forwards the real-time video request to the current scheduled central server.

And step S15, the current central server schedules a stream server according to the scheduling strategy and acquires the stream receiving address of the scheduled current stream server.

And S16, the current central server sends an instruction for pushing a real-time video stream to the current streaming server to the equipment access gateway, wherein the real-time video stream is shot by the monitoring equipment, and the instruction comprises the streaming receiving address.

And step S17, after receiving the instruction, the equipment access gateway establishes connection to the current streaming server according to the streaming receiving address and sends a request for pushing a real-time video to the monitoring equipment.

Step S18, when receiving the real-time video stream pushed by the monitoring device, the device access gateway forwards the real-time video stream to the current stream server, and returns the execution result of the instruction to the current central server.

Step S19, the current central server judges whether the equipment access gateway successfully pushes the real-time video stream to the current streaming server according to the execution result.

When it is determined that the device access gateway does not successfully push the real-time video stream to the current streaming server, step S20 is executed, and when it is determined that the device access gateway successfully pushes the real-time video stream to the current streaming server, steps S21 to S25 are executed.

And step S20, the current central server responds an error code to the client through the current access server.

The error code may be preset, so that when the device access gateway does not successfully push the real-time video stream to the current streaming server, the preset error code is returned to the current access server, so that the current access server rotates the preset error code to the client, and the client can know that the video access request sent by the client fails according to the preset error code.

And step S21, the current central server responds the stream receiving address to the client through the current access server.

And step S22, the client acquires the real-time video stream from the current stream server according to the stream receiving address.

Step S23, when it is detected that the client disconnects the video access and a preset time elapses, the current streaming server generates a video access end notification, and sends the video access end notification to the current central server.

And step S24, the current central server sends an instruction for stopping pushing the real-time video stream to the current stream server to the equipment access gateway.

And step S25, the equipment access gateway removes the connection with the current streaming server, sends a request for stopping pushing the real-time video to the monitoring equipment, and returns an execution result to the central server.

It can be understood that, when receiving the request for stopping pushing the real-time video, the monitoring device stops pushing the shot real-time video stream to the device access gateway.

In addition, after the step of scheduling, by the access balancing server, one access server according to a scheduling policy, the video access method further includes:

and when the access balancing server detects that the current access server is down, the access balancing server dispatches the video access request to another access server.

In summary, compared with the video access method in the first embodiment, the video access method in this embodiment implements service keep-alive detection of the access servers by accessing the balancing server, and when any access server is found to be down, the video access request responded by the access server can be dispatched to other idle or relatively idle access servers for responding, thereby ensuring high availability of the video access service. In addition, after the user disconnects the video connection between the client and the streaming server, the streaming server sends a notification of stopping video push to the central server after waiting for a period of time, so that the user can quickly recover the video connection when the client network shakes (becomes unstable).
