Network monitoring equipment uses a network, rather than a point-to-point analog video cable, to transmit video and other various monitoring-related information.
In the embodiment of the present invention, the type of the monitoring device is not specifically limited, and what technique is used by the monitoring device to detect the number of people is not specifically limited, as long as the result of detecting the number of people in the monitoring range can be achieved.
The staff aggregation
When the number of the personnel in the monitoring range exceeds a set threshold value, the personnel density is over high, and the police is required to take safety precaution on the area, so that the monitoring equipment generates personnel gathering alarm information. The content of the personnel gathering alarm information may include: time, place, personnel number, monitoring equipment identification, protocol server identification and the like. The alarm information may be a data packet generated under an ethernet protocol, for example, the ethernet protocol may be a TCP/IP protocol, and the data packet may be an IP data packet or a TCP data packet. Specifically, before forwarding an IP data packet to the protocol conversion server, the monitoring device obtains the MAC address of the default protocol conversion server through an ARP request, where the data packet may carry a source IP address of the monitoring device, a target IP address of a monitoring management platform to be finally reached, and a MAC address set for monitoring and a MAC address of the protocol conversion server.

When the number of people is less than the set threshold value, the alarm indicating the people gathering is released, and the safety precaution of the area can be degraded correspondingly. At this time, the monitoring equipment generates personnel recovery alarm information to inform the monitoring management center that the number of personnel in the area is recovered to be normal. The personnel recovery warning information may include: time, place, personnel number, monitoring equipment identification, protocol server identification and the like.
According to the embodiment of the invention, the personnel recovery warning module is arranged in the monitoring equipment, and the monitoring management platform can timely know that the quantity of personnel in the area is changed from gathering to normal by sending the personnel recovery warning information, so that the monitoring management personnel can adjust the security measures according to the real-time condition, the security work is more targeted, and the waste of security resources is avoided.

A protocol server, i.e., a protocol gateway, which is used between two systems with different communication protocols, data formats or languages, even completely different architectures, and which enables hosts on the communication network using different higher layer protocols to still cooperate with each other is a "gateway" where networks are connected to another networks.
The path information in the embodiment of the present invention is obtained according to a preset corresponding relationship between a protocol server and a monitoring management platform, and is used for identifying a transmission path of the video network information data packet in the video network, including a source IP address and a destination IP address of the alarm information, where the source IP address is an IP address of the monitoring device, and the destination IP address is an IP address of the monitoring management platform, the monitoring device encapsulates the IP data packet into an ethernet data frame at a data link layer, and then sends the ethernet data frame to a default protocol server according to the destination MAC address, when the protocol server receives the ethernet data frame, it finds that the destination MAC address in the data frame is a physical address of a port of the protocol server, and at this time, the protocol server will remove the encapsulation of the ethernet data frame, that is, remove the MAC address and the source MAC address of the protocol server, change the source IP address of the protocol server into the IP address of the protocol server, and the protocol server matches with a routing table through the destination IP address of the IP data packet, and sends the packet to a next network if the destination IP address is a destination network entry, and then forwards the network entry to a next network .
In the embodiment of the invention, the cooperative conversion server not only plays a role of a gateway in network connection, but also can convert the format of the data packet transmitted by the monitoring equipment. Because the alarm information generated by the monitoring equipment is a data packet which is suitable for transmission in the ethernet environment and does not conform to the specification of the video networking protocol on the data transmission format, the monitoring equipment needs to rely on the protocol conversion server to convert the video networking information data packet which conforms to the video networking protocol.

an adding
In the embodiment of the invention, the assistant server removes the IP protocol packet header of the alarm information data packet sent by the monitoring equipment and adds the upper view networking protocol packet header; and modifying the field indicating the path information in the data packet, namely changing the source IP address into the IP address of the protocol conversion server, wherein the destination IP address is unchanged.
And the encapsulating
And the protocol conversion server encapsulates the modified data packet in a video networking protocol message body. Therefore, the warning information data packet adaptive to Ethernet transmission becomes a video networking information data packet which can be transmitted in a video networking environment.
In the embodiment of the invention, the protocol conversion server converts the alarm information data packet into a data format suitable for transmission in the video network by adding the packet header and modifying the path information for the alarm information, and carries the transmission path information, so that the alarm information can be smoothly transmitted in the video network and accurately reaches a destination network.
And the
And the protocol conversion server sends the converted video network information data packet with the destination IP to a lower hop route positioned in the video network, and the lower hop route is matched with the network according to the destination IP until the video network information data packet reaches a video network server where the destination network is positioned.
The video networking server 503 specifically includes a sending module 5031, configured to send the video networking information data packet to the monitoring management platform that has accessed the video networking server according to the path information.
And the video networking server sends the video networking information data packet to a monitoring management platform corresponding to the target IP address. Therefore, the alarm information data packet sent by the monitoring equipment in the Ethernet reaches the target monitoring management platform in the video network, and the information transmission from the Ethernet to the video network is realized.
