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, the invention provides one of the core concepts of the embodiment of the invention, and a monitoring method based on a monitoring system is adopted to meet the requirement of saving server resources.
Referring to fig. 5, a schematic diagram of a monitoring system of the present invention is shown, the monitoring system includes a plurality of monitoring networks, a monitoring server with a multi-network card, a video network server and a plurality of video network terminals, the monitoring network includes at least one monitoring device;
each monitoring network uses a special network card to access the monitoring server through the Internet; the monitoring server is connected with the video network server based on the video network.
In this embodiment, the monitoring server has multiple network cards, and each monitoring network uses a dedicated network card to access the monitoring server, as shown in fig. 5, the monitoring networks 1 to 5 access the monitoring server. The access protocol is an internet protocol, and preferably, the interface mode of the network card includes at least one of sdk, rtsp, and gb 28181. For example, the dedicated network card used for the monitoring network 1 adopts an sdk interface method, and the dedicated network card used for the monitoring network 2 adopts an rtsp interface method. The embodiment of the present invention is not limited in detail, and may be set according to actual situations.
Each monitoring network comprises at least one monitoring device, and preferably, the monitoring device comprises at least one of NVR, DVR, IPcamer and encoder. For example, the monitoring network 1 includes NVR, and the monitoring network 2 includes DVR and IPcamer. The embodiment of the present invention is not limited in detail, and may be set according to actual situations.
The monitoring server is connected with the video network server based on the video network, and the video network server is connected with a plurality of video network terminals. The monitoring server performs connection and conversion functions in an internet-based monitoring network and an internet-of-view server.
Referring to fig. 6, a flowchart illustrating steps of an embodiment of a monitoring method based on a monitoring system according to the present invention is shown, which may specifically include the following steps:
In this embodiment, when the monitoring network uses a dedicated network card to access the monitoring server, the monitoring server configures a unique corresponding first network address for the monitoring device in the monitoring network. For example, the monitoring network 1 uses the network card 1 to access the monitoring server, the monitoring network 2 uses the network card 2 to access the monitoring server, the monitoring network 1 includes NVR, and the monitoring network 2 includes DVR and IPcamer, so that the monitoring server configures a first network address a.01 for the NVR in the monitoring network 1, configures a first network address a.02 for the DVR in the monitoring network 2, and configures a first network address a.03 for the IP camer in the monitoring network 2.
And the monitoring server establishes a first corresponding relation between the first network address and a monitoring network where the monitoring equipment is located and a second network address in the monitoring network where the monitoring equipment is located. For example, after the monitoring server configures a first network address a.01 for the NVR in the monitoring network 1, a first corresponding relationship among the first network address a.01, the monitoring network 1, and a second network address b.01 of the NVR in the monitoring network 1 is established. After configuring a first network address a.02 for the DVR in the monitoring network 2, the monitoring server establishes a first corresponding relationship among the first network address a.02, the monitoring network 2, and a second network address b.01 of the DVR in the monitoring network 2.
The monitoring server establishes a second corresponding relation between the monitoring network and the corresponding special network card. For example, the monitoring server establishes a corresponding relationship between the monitoring network 1 and the network card 1, and a corresponding relationship between the monitoring network 2 and the network card 2.
In this embodiment, after configuring the first network address for the monitoring device in each monitoring network, the monitoring server sends the configured first network address to the video network server, and sends the configured first network address to the video network terminal through the video network server. For example, after configuring the first network address for the NVR of the monitoring network 1 and the DVR and the IP client in the monitoring network 2, the monitoring server sends the configured a.01, a.02, and a.03 to the video networking server, and the video networking server sends the a.01, a.02, and a.03 to the video networking terminal 2.
In this embodiment, after the first network address configured by the monitoring server is sent to the video networking terminal, the display device may be set at the video networking terminal for display, and the user selects the first target network address from the plurality of first network addresses. For example, the terminal 2 of the video network receives a.01, a.02 and a.03 and then displays the received signals, and the user selects a.02 from the received signals.
And the video network terminal receives the first target network address selected by the user and then sends the first target network address to the monitoring server through the video network server. The monitoring server receives a first target network address selected from a plurality of first network addresses through the video network terminal. For example, after the user selects a.02, the video network terminal sends the a.02 to the monitoring server through the video network server, and the monitoring server receives the first target network address a.02.
In this embodiment, after receiving the first target network address, the monitoring server determines, according to the first correspondence, a target monitoring network corresponding to the first target network address and a second target network address in the target monitoring network. For example, after receiving the first target network address a.02, the monitoring server determines that the target monitoring network is the monitoring network 2 according to the corresponding relationship between a.02 and the monitoring network 2, and determines that the second target network address in the target monitoring network is b.01 in the monitoring network 2 according to the corresponding relationship between a.02 and b.01 in the monitoring network 2.
And determining a target network card corresponding to the target monitoring network according to the second corresponding relation. For example, if the monitoring network 2 corresponds to the network card 2, the target network card is the network card 2.
In this embodiment, after determining the second target network address and the target network card in the target monitoring network, an internet communication channel between the second target network address and the target network card in the target monitoring network is established. For example, the monitoring server establishes an internet communication channel between b.01 in the monitoring network 2 and the network card 2. The communication channel may adopt Socket or other modes, which is not limited in detail in the embodiment of the present invention and may be set according to actual situations.
In this embodiment, after the internet communication channel is established, the monitoring server sends the command for acquiring the video image to the target monitoring device. For example, if the monitoring server establishes a communication channel between b.01 and the network card 2 in the monitoring network 2, the monitoring server sends a command for acquiring a video image to the DVR in the monitoring network 2. The established internet communication channel is between the second target network address and the target network card in the target monitoring network, so that the command for acquiring the video image can be accurately transmitted. For example, if the monitoring server establishes a communication channel between b.01 and the network card 2 in the monitoring network 2, the command for acquiring the video image will not be sent to the NVR corresponding to b.01 in the monitoring network 1, and the command for acquiring the video image will not be sent to the IP camera corresponding to b.02 in the monitoring network 2.
And 507, receiving a video image which is acquired by the target monitoring equipment according to the video image acquisition command and fed back through the internet communication channel.
In this embodiment, the target monitoring device receives a command for acquiring a video image, which is sent by the monitoring server through the internet communication channel, acquires the video image according to the command, and sends the acquired video image to the monitoring server through the internet communication channel. And the monitoring server receives the video image fed back by the target monitoring equipment. For example, the monitoring server sends a command for acquiring a video image to a DVR corresponding to b.01 in the monitoring network 2 through an internet communication channel, the DVR feeds the video image back to the monitoring server through the internet communication channel after acquiring the video image, and the monitoring server receives the video image fed back by the DVR.
And step 508, sending the video image to the video network terminal based on the video network.
In this embodiment, the monitoring server receives the video image fed back by the target monitoring device, and sends the video image to the video networking server, and the video networking server sends the video networking server to the video networking terminal. For example, when the terminal 2 selects the first target network address, the monitoring server sends the acquired video image to the video network server, and then the video network server sends the video image to the terminal 2.
In summary, in the embodiment of the present invention, each monitoring network uses a dedicated network card to access the monitoring server with multiple network cards through the internet; the method comprises the steps that a monitoring server configures a first network address uniquely corresponding to monitoring equipment in a plurality of monitoring networks; sending the configured first network address to a video network terminal through a video network server; receiving a first target network address selected by a video network terminal; determining a target monitoring network corresponding to the first target network address, a second target network address in the target monitoring network and a target network card; establishing an internet communication channel, and acquiring a video image through the internet communication channel; and sending the video image to the video network terminal based on the video network. By the embodiment of the invention, one monitoring server with multiple network cards can access multiple monitoring networks simultaneously, so that server resources are saved; and the monitoring server configures a first network address uniquely corresponding to the monitoring equipment in the monitoring network, and establishes an internet communication channel with the target monitoring equipment after the video networking terminal selects the first target network address, so that the video image is accurately acquired, and the situation that the video image is acquired by mistake when the monitoring equipment in different monitoring networks has the same network address is avoided.

In this embodiment, the video image sent to the monitoring server by the target monitoring device is a video image based on an internet protocol, and after receiving the video image fed back by the target monitoring device, the monitoring server converts the video image based on the internet protocol into a video image based on a video networking protocol. For example, the monitoring server receives a video image sent by a DVR in the monitoring network 2, the DVR sends a video image based on the internet protocol, and the monitoring server converts the video image fed back by the DVR into a video image based on the video internet protocol.
In this embodiment, the video image based on the video networking protocol after the conversion is sent to the video networking server by the monitoring server, and the video networking server can read the video image and also can store the video image, and simultaneously the video image based on the video networking protocol is sent to the video networking terminal, and the video networking terminal can show the video image and also can store the video image.
