2. Video networking packet definition

2.1 Access network packet definition

The data packet of the access network mainly comprises the following parts: destination Address (DA), Source Address (SA), reserved bytes, payload (pdu), CRC.

As shown in the following table, the data packet of the access network mainly includes the following parts:

DA

SA

Reserved

Payload

CRC

wherein:

the Destination Address (DA) is composed of 8 bytes (byte), the first byte represents the type of the data packet (such as various protocol packets, multicast data packets, unicast data packets, etc.), there are 256 possibilities at most, the second byte to the sixth byte are metropolitan area network addresses, and the seventh byte and the eighth byte are access network addresses;

the Source Address (SA) is also composed of 8 bytes (byte), defined as the same as the Destination Address (DA);

the reserved byte consists of 2 bytes;

the payload part has different lengths according to different types of datagrams, and is 64 bytes if the datagram is various types of protocol packets, and is 32+1024 or 1056 bytes if the datagram is a unicast packet, of course, the length is not limited to the above 2 types;

the CRC consists of 4 bytes and is calculated in accordance with the standard ethernet CRC algorithm.

2.2 metropolitan area network packet definition

The topology of a metropolitan area network is a graph and there may be 2, or even more than 2, connections between two devices, i.e., there may be more than 2 connections between a node switch and a node server, a node switch and a node switch, and a node switch and a node server. However, the metro network address of the metro network device is unique, and in order to accurately describe the connection relationship between the metro network devices, parameters are introduced in the embodiment of the present invention: a label to uniquely describe a metropolitan area network device.

In this specification, the definition of the Label is similar to that of the Label of MPLS (Multi-Protocol Label Switch), and assuming that there are two connections between the device a and the device B, there are 2 labels for the packet from the device a to the device B, and 2 labels for the packet from the device B to the device a. The label is classified into an incoming label and an outgoing label, and assuming that the label (incoming label) of the packet entering the device a is 0x0000, the label (outgoing label) of the packet leaving the device a may become 0x 0001. The network access process of the metro network is a network access process under centralized control, that is, address allocation and label allocation of the metro network are both dominated by the metro server, and the node switch and the node server are both passively executed, which is different from label allocation of MPLS, and label allocation of MPLS is a result of mutual negotiation between the switch and the server.

As shown in the following table, the data packet of the metro network mainly includes the following parts:

DA

SA

Reserved

label (R)

Payload

CRC

Namely Destination Address (DA), Source Address (SA), Reserved byte (Reserved), tag, payload (pdu), CRC. The format of the tag may be defined by reference to the following: the tag is 32 bits with the upper 16 bits reserved and only the lower 16 bits used, and its position is between the reserved bytes and payload of the packet.

Based on the characteristics of the video network, one of the core concepts of the embodiment of the invention is provided, the embodiment of the invention can be applied to a monitoring system, the monitoring system comprises a video network processor, a video network access device, a streaming media server and an internet monitoring terminal, and the internet monitoring terminal is connected with the video network processor through the video network access device; the embodiment of the invention can be applied to a video network access device, and firstly, an information acquisition request is sent to the internet monitoring terminal; then receiving monitoring information sent by the internet monitoring terminal according to the information acquisition request; and then, the monitoring information is sent to a video networking processor through the streaming media server, so that the video networking processor determines whether the monitoring information contains early warning information or not, and sends the early warning information to a processing platform in the video networking when the early warning information exists in the monitoring information. Therefore, the video networking processor is adopted to process the monitoring information collected by the video networking monitoring terminal, and the video networking technology can realize the real-time transmission of the full-network high-definition video which cannot be realized by the current internet, so that the information quality and the transmission speed of the monitoring information are improved, and the information safety is improved.

Referring to fig. 5, a flowchart of steps of an embodiment of a monitoring method based on a video network according to the present invention is shown, and the method can be applied to a monitoring system, wherein the monitoring system includes a video network processor, a video network accessor, a streaming media server, and an internet monitoring terminal, and the internet monitoring terminal is connected with the video network processor through the video network accessor.

In this embodiment of the present invention, the monitoring terminal may be a Digital Video Recorder (DVR), a Network Video Recorder (NVR), an IP-based Network Camera (IP Network Camera, IPCAM), and the like, which is not limited in this embodiment of the present invention.

The method is applied to the video network access device, and specifically comprises the following steps:

step 501: and sending an information acquisition request to the Internet monitoring terminal.

Wherein, can set up the corresponding video network access device in each monitoring area, dispose a plurality of internet monitor terminal in this monitoring area, like this, be connected with the internet monitor terminal in this monitoring area in advance through this video network access device to after the internet monitor terminal in video network access device and this monitoring area is connected, this video network access device can send information acquisition request to this internet monitor terminal, in order to realize transmitting the control data that internet monitor terminal gathered to the video network.

In the embodiment of the invention, the internet monitoring terminal can acquire the monitoring information in the preset monitoring range of the internet monitoring terminal in real time, so that the video network access device requests to acquire the monitoring information by sending an information acquisition request to the internet monitoring terminal. In a possible implementation manner, the information acquisition request may include an access identifier corresponding to the video network access device, and thus, after receiving the information acquisition request, the internet monitoring terminal determines whether the video network access device is an access device for establishing a connection relationship in advance through the access identifier, and when determining that the video network access device is an access device for establishing a connection relationship in advance, the video network access device has a permission for acquiring the monitoring information acquired by the internet monitoring terminal, and when determining that the video network access device is not an access device for establishing a connection relationship in advance, the video network access device does not have a permission for acquiring the monitoring information acquired by the internet monitoring terminal, thereby improving the security of information interaction.

In this embodiment, the video network access device may send the information acquisition request by using an internet protocol (e.g., an IP protocol).

Step 502: and receiving the monitoring information sent by the Internet monitoring terminal according to the information acquisition request.

In the embodiment of the present invention, the internet monitoring terminal also uses an internet protocol to send the monitoring information to the video network access device, and the monitoring information may be video information or audio information.

Step 503: and sending the monitoring information to a video networking processor through the streaming media server so that the video networking processor can determine whether the monitoring information contains early warning information or not, and sending the early warning information to a processing platform in the video networking when the early warning information exists in the monitoring information.

In the embodiment of the invention, the monitoring information can be subjected to information analysis through deep learning and GPU image processing technologies so as to determine whether the monitoring information contains early warning information or not. Illustratively, the warning information may be information about the existence of a traffic accident, a fire, a vehicle congestion, a crowd, and the like.

Wherein, this step adopts the internet of vision protocol (such as V2V protocol), through the flow media server, send this monitoring information to the internet of vision processor. In addition, when the early warning information is sent to a processing platform in the video network, the early warning information needs to be transmitted through the streaming media server.

In summary, the video network access device firstly sends an information acquisition request to the internet monitoring terminal; then receiving monitoring information sent by the internet monitoring terminal according to the information acquisition request; and finally, the monitoring information is sent to a video networking processor through the streaming media server, so that the video networking processor can determine whether the monitoring information contains early warning information or not, and send the early warning information to a processing platform in the video networking when the early warning information exists in the monitoring information. Therefore, the video networking processor is adopted to process the monitoring information collected by the video networking monitoring terminal, and the video networking technology can realize the real-time transmission of the full-network high-definition video which cannot be realized by the current internet, so that the information quality and the transmission speed of the monitoring information are improved, the transmission delay is reduced, and the information safety is improved.

Referring to fig. 6, a flowchart illustrating specific steps of an embodiment of a monitoring method based on a video network according to the present invention is shown, and the method can be applied to a monitoring system, as shown in fig. 7, the monitoring system includes a video network processor, a video network accessor, a streaming media server, and an internet monitoring terminal, and the internet monitoring terminal is connected with the video network processor through the video network accessor.

The method specifically comprises the following steps:

step 601: and the video network access device sends a video network access request message to the internet monitoring terminal.

Since the internet monitoring terminal may be manufactured by different manufacturers and have different models, when the internet monitoring terminal is initially put into use, in order to ensure information security, the internet monitoring terminal needs to be authenticated by the video network access device, and the specific process is from step 601 to step 603.

The internet monitoring terminal in this step may be: in the monitoring area corresponding to the video network accessor, a terminal which is not connected to the video network accessor is provided, so that the video network accessor can broadcast a video network access request message in the monitoring area corresponding to the video network accessor according to a preset period, or the video network accessor acquires a plurality of internet monitoring terminals in the monitoring area and determines the internet monitoring terminals which are not connected, and thus the video network access request message is sent to the internet monitoring terminals which are not connected.

In this step, the video network access device sends a video network access request message to the internet monitoring terminal by adopting an internet protocol.

Step 602: and the video network access device receives a response message sent by the internet monitoring terminal according to the video network access request message.

The internet monitoring terminal in this step adopts an internet protocol to send the response message.

Step 603: the video network accessor determines whether the response message is an access response message.

When the response message is an access response message, executing step 604 and step 606;

when the response message is an access reject message, step 605 is performed.

And step 604, the video network access device sends an information acquisition request to the internet monitoring terminal.

When the response message is an access response message, the video network access device needs to be connected with the unconnected internet monitoring terminal, for example, a connection relationship can be established between a terminal identifier of the unconnected internet monitoring terminal and an access identifier corresponding to the video network access device. For example, if the video network accessor a (i.e. an access identifier) is used to transmit monitoring data collected by the internet monitoring terminal in the monitoring area B to the video network, and the unconnected internet monitoring terminal in the monitoring area B includes the monitoring terminal B1, the monitoring terminals B2, …, and the monitoring terminal Bn, where n is an integer greater than 1, a connection relationship may be sequentially established between the device identifiers B1, B2, …, Bn of the monitoring terminal and the access identifier a of the video network accessor, so as to complete the connection between the video network accessor and the internet monitoring terminal, and in this step, after the video network accessor is connected with the internet monitoring terminal, the monitoring information is obtained from the internet monitoring terminal.

Step 605, the video network access device generates a terminal list according to the access rejection message.

In this way, the video network access device does not send an information acquisition request to the internet monitoring terminals in the terminal list.

And 606, receiving the monitoring information sent by the internet monitoring terminal according to the information acquisition request by the video network access device.

The internet monitoring terminal adopts an internet protocol to send the monitoring information to the video network access device.

Step 607, the internet access device converts the internet protocol of the monitoring information transmission into the internet protocol.

Step 608, the video network access device sends the monitoring information to the video network processor through the streaming media server by using the video network protocol.

Wherein the video networking protocol may be a V2V protocol.

Step 609, the video networking processor determines whether the monitoring information contains early warning information.

When the monitoring information contains early warning information, executing step 610;

if there is no warning information in the monitoring information, the process returns to step 604.

In this step, first, sample information (for example, the sample information may be video information, audio information, or the like) with known labeling results may be collected in advance, and the sample information may be preprocessed, for example, noise filtered, normalized, or the like; then, training the sample information through deep learning and GPU image processing technologies to obtain an early warning analysis model; finally, the monitoring information may be input into the early warning analysis model to obtain an analysis result corresponding to the monitoring information, where the analysis result may be whether there is early warning information, and when the analysis result indicates that there is early warning information, the type of the early warning information may also be determined by the early warning analysis model, and for example, the early warning information may be information such as traffic accidents, fires, vehicle congestion, crowd aggregation, and the like, and the above examples are only examples, and the disclosure does not limit this.

And step 610, the video network processor sends the early warning information to a processing platform in the video network.

Therefore, the incident place corresponding to the early warning information can be obtained through the processing platform, the monitoring terminals of a plurality of directions in the preset position range of the incident place are determined, the user can determine the target monitoring terminal from the monitoring terminals, the target monitoring terminal is called through the user terminal to check the current incident state, and event processing is carried out according to the current incident state.

It should be noted that, for simplicity of description, the method embodiments are described as a series of acts or combination of acts, but those skilled in the art will recognize that the present invention is not limited by the illustrated order of acts, as some steps may occur in other orders or concurrently in accordance with the embodiments of the present invention.
