Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The camera network distribution method provided by the application can be applied to the application environment shown in fig. 1. The first image capturing device 102, the video monitoring management platform 104, and the second image capturing device 106 may communicate with each other in the same local area network through a network. The video monitoring management platform 104 may send a multicast detection message to the local area network, the first image capturing device 102 may detect the multicast detection message sent by the video monitoring management platform 104 in the local area network, and obtain a first IP address of the video monitoring management platform 104 based on the multicast detection message, the first image capturing device 102 may further obtain its own MAC address and MAC addresses of a plurality of second image capturing devices 106, and determine a master proxy image capturing device therefrom, if the first image capturing device 102 is a master proxy image capturing device, the first image capturing device 102 obtains a plurality of address information to be allocated based on the first IP address information, thereby allocating target address information to the home terminal and the slave proxy image capturing devices, and the second image capturing device 106 including the slave proxy image capturing device may receive the target address information sent by the first image capturing device 102 from the local area network and modify its own corresponding address information, when the proxy image acquisition device is the slave proxy image acquisition device, the information distributed by the master proxy image acquisition device is received. So that the home agent and slave agent image capture devices can establish communication with the video surveillance management platform 104, respectively. The first image capturing device 102 and the second image capturing device 106 may be, but not limited to, various personal computers, notebook computers, smart phones, tablet computers, cameras, and portable wearable devices that can capture images, the second image capturing device 106 may include one or more devices, and the video monitoring management platform 104 may be implemented by an independent server or a server cluster formed by a plurality of servers.
In an embodiment, as shown in fig. 2, a camera network distribution method is provided, which is described by taking the method as an example for being applied to the first image capturing device in fig. 1, and includes the following steps:
step S202, a multicast detection packet sent by the video monitoring management platform 104 in the local area network is detected, and a first IP address of the video monitoring management platform 104 is obtained based on the multicast detection packet.
The first image capturing device 102 may be a camera, the video monitoring Management platform 104(VMS, View Management System) may be a System local area network for performing video monitoring, and may be a network including a plurality of devices, the local area network may include the first image capturing device 102, the video monitoring Management platform 104, the second image capturing device 106, and other devices, and the plurality of devices in the local area network may be produced by different manufacturers and may be in different network segments, which may result in that communication between the devices is not possible. In order to establish communication among the devices in the local area network, the video monitoring management platform 104 may send a multicast probe packet to the local area network, and the first image capturing device 102 may detect the multicast probe packet in the local area network, and may obtain the first IP address of the video monitoring management platform 104 based on the multicast probe packet after receiving the multicast probe packet, so that a process of address information allocation may be performed based on the first IP address. For example, each device in the lan may be an ONVIF interface compatible device, an ONVIF being a global open industry forum aimed at facilitating the development and use of global open standards for physical IP-based security product interfaces. ONVIF creates a standard for how IP products in video surveillance and other physical security areas communicate with each other. The first image acquisition device 102 may open an ONVIF multicast port for monitoring, and the video monitoring management platform 104 may send a standard ONVIF multicast detection message to the local area network, detect a network camera in the local area network that monitors the ONVIF multicast, and after the camera receives the ONVIF multicast detection message, the camera may resolve an encoded IP address of the video monitoring management platform 104 from the message.
Step S204, obtaining the MAC address of the first image acquisition device 102 and obtaining the MAC addresses of a plurality of second image acquisition devices 106 in the local area network; one of the first image capturing apparatus 102 and the second image capturing apparatus 106 is determined as a master proxy image capturing apparatus based on the comparison result of the plurality of MAC addresses.
The second image capturing device 106 may be a device disposed in the same local area network as the first image capturing device 102, and may be a camera, for example. The first image capturing device 102 may perform a process of detecting and modifying address information after receiving the multicast probe packet sent by the video monitoring management platform 104, so that each device in the local area network may communicate with each other. The process may be a modified process based on each image capturing device in the local area network, that is, an image capturing device for assigning an address needs to be determined. The first image capturing device 102 may obtain its MAC (Media Access Control Address) Address and MAC addresses of a plurality of second image capturing devices 106 in the lan. The MAC Address is also called a local area network Address (LAN Address), a MAC Address, an Ethernet Address (Ethernet Address) or a Physical Address (Physical Address), and is an Address for confirming the location of the network device. The first image capturing device 102 may acquire MAC addresses of a plurality of second image capturing devices 106 from the local area network based on a set protocol.
After obtaining the MAC address of the first image capturing device 102 and the MAC addresses of the second image capturing devices 106 in the local area network, the first image capturing device 102 may compare the obtained MAC addresses, and based on a comparison result, the first image capturing device 102 may determine one device as a master proxy image capturing device from the first image capturing device 102 and the second image capturing devices 106. For example, in one embodiment, determining one image capture device from the first image capture device and the second image capture device as a master proxy image capture device based on a comparison of the plurality of MAC addresses comprises: obtaining a maximum value of a plurality of MAC addresses; and taking the image acquisition equipment corresponding to the maximum value as main proxy image acquisition equipment. In this embodiment, the first image capturing device 102 may compare the received multiple MAC addresses, and use the image capturing device corresponding to the maximum value of the multiple MAC addresses as a master proxy image capturing device. For example, the first image capturing device 102 may compare MAC addresses of all acquired online cameras to find a camera with the largest MAC address. The camera with the largest MAC address serves as the only master proxy camera, and the rest cameras are all slave proxy cameras. The master proxy camera is used for allocating information such as an IP address to the slave proxy camera, and the slave proxy camera waits for the information such as the IP address allocated by the master proxy. It should be noted that, the first image capturing device 102 and each second image capturing device 106 in the local area network may both perform the above processes of acquiring the MAC address and determining the master proxy image capturing device, so that each device in the local area network may achieve the consensus between the master proxy image capturing device and the slave proxy image capturing device.
Step S206, if the first image acquisition device 102 is a master proxy image acquisition device, obtaining a plurality of pieces of address information to be allocated according to the first IP address, and allocating target address information to the home terminal and the slave proxy image acquisition devices respectively based on the plurality of pieces of address information to be allocated, so that the home terminal and the slave proxy image acquisition devices respectively establish communication with the video monitoring management platform 104; the slave proxy image capturing apparatus is an image capturing apparatus other than the master proxy image capturing apparatus among the first image capturing apparatus 102 and the second image capturing apparatus 106.
The slave proxy image capturing device may be an image capturing device other than the master proxy image capturing device among the first image capturing device 102 and the plurality of second image capturing devices 106. When the first image capturing device 102 determines that its MAC address is the maximum in the MAC address comparison, it may be determined that the first image capturing device 102 is the master proxy image capturing device, and then the first image capturing device 102 serving as the master proxy image capturing device may perform address information allocation for other slave proxy image capturing devices in the local area network. In this process, the first image capturing device 102 may obtain a plurality of pieces of address information to be allocated based on the first IP address of the video surveillance management platform 104, and the plurality of pieces of address information to be allocated may be address information with which the video surveillance management platform 104 may establish communication. Since the first image capturing device 102 and the plurality of second image capturing devices 106 including the slave image capturing devices may include devices that cannot communicate with the video monitoring management platform 104, for example, devices that cross a network segment with the video monitoring management platform 104, after the first image capturing device 102 obtains a plurality of pieces of address information to be allocated, the first image capturing device may allocate target address information to the home terminal and each slave image capturing device, so that the home terminal and each slave image capturing device establish communication with the video monitoring management platform 104.
Step S208, if the first image acquisition equipment is slave proxy image acquisition equipment, acquiring target address information distributed by the master proxy image acquisition equipment aiming at the first image acquisition equipment from the local area network; and establishing communication with the video monitoring management platform according to the target address information.
For example, after the first image capturing device 102 compares the multiple MAC addresses, the largest MAC address is not the MAC address of the home terminal, and then the first image capturing device 102 may know that the home terminal is the slave image capturing device. The first image capturing device 102 serving as a slave image capturing device may acquire, from the local area network, target address information assigned by the master proxy image capturing device to the first image capturing device 102, so that the first image capturing device 102 may modify, based on the target address information, corresponding address information of the local terminal, and may communicate with each other device in the local area network based on the modified address information.
For example, as shown in fig. 3, fig. 3 is a schematic flow chart of a network distribution step from the proxy image capturing device in one embodiment. The first image capturing device 102 may be a camera, and the first image capturing device 102 is a slave proxy image capturing device, where the first image capturing device 102 may wait for the master proxy camera to assign information such as an IP address, and the master proxy camera may send heartbeat packets to the local area network at intervals, and if the first image capturing device 102 receives information such as an IP address assigned by the master proxy camera and is communicated with the VMS within a preset time, the process ends; otherwise, after the preset time is exceeded, the slave proxy camera can use a random algorithm to detect and obtain information such as a non-conflict IP address, a subnet mask and the like communicated with the VMS through an ARP protocol, and the information is used as the IP address, the subnet mask and the like of the slave proxy camera. Through the steps, when the first image capturing device 102 is used as a slave image capturing device, the address information allocated to the first image capturing device by the master image capturing device can be received within the set time, and the address information capable of being communicated can be automatically calculated when the set time is exceeded, so that the communication with the video monitoring management platform 104 is established, and the effect of communication across network segment devices in the local area network is achieved.
In the camera network distribution method, the first image acquisition equipment is used for acquiring the first IP address of the video monitoring management platform based on the multicast detection message in the local area network, and determining one image acquisition device as a master proxy image acquisition device based on the MAC address of the first image acquisition device and the MAC addresses of a plurality of second image acquisition devices in the local area network, if the first image acquisition device is the master proxy image acquisition device, obtaining a plurality of pieces of address information to be allocated according to the first IP address, allocating target address information to the home terminal and the slave image acquisition device respectively based on the plurality of pieces of address information to be allocated, for the local terminal and the slave agent image acquisition equipment except the master agent image acquisition equipment to respectively establish communication with the video monitoring management platform, when the proxy image acquisition device is the slave proxy image acquisition device, the information distributed by the master proxy image acquisition device is received. Compared with the situation that the traditional equipment crossing network segments cannot communicate, the scheme selects the image acquisition equipment for allocating the address capable of communicating with the management platform from the plurality of image acquisition equipment and allocates the address, so that the effect of enabling the equipment crossing network segments to communicate is achieved.
In one embodiment, obtaining the address information to be allocated according to the first IP address includes: acquiring a plurality of IP addresses to be distributed and a plurality of subnet masks to be distributed corresponding to the IP addresses to be distributed according to a preset random algorithm, and using the IP addresses to be distributed and the subnet masks to be distributed as a plurality of groups of address information to be distributed; the plurality of IP addresses to be allocated do not conflict with the first IP address; the number of the plurality of groups of address information to be allocated corresponds to the number of the first image acquisition devices and the second image acquisition devices.
In this embodiment, the first IP address may be an IP address of the video monitoring management platform 104, and after the first image capturing device 102 determines that the home terminal is a master proxy image capturing device, the process of allocating address information to a slave proxy image capturing device may be executed. In the process, the first image capturing device 102 may obtain, as the information of the plurality of groups of addresses to be allocated, a plurality of IP addresses to be allocated and a plurality of subnet masks to be allocated corresponding to the IP addresses to be allocated by using a preset random algorithm. The plurality of IP addresses to be allocated do not conflict with the first IP address, and the number of the plurality of sets of address information to be allocated corresponds to the number of the first image capturing device 102 and the second image capturing device 106, so that each image capturing device can obtain a set of address information that is not allocated from the address information to be allocated when the target address information needs to be allocated. For example, the first image capturing device 102 may use a random algorithm to obtain information, such as a non-conflicting IP Address and a subnet mask, which is communicated with the VMS (video monitoring management platform 104) through an ARP (Address Resolution Protocol) Protocol detection. The ARP protocol is a TCP/IP protocol for acquiring a physical address according to an IP address.
Through this embodiment, the first image capturing device 102 may obtain multiple sets of address information to be allocated by using a random algorithm and an ARP protocol, so as to allocate address information to devices across network segments, thereby implementing communication between devices across network segments in a local area network.
In one embodiment, allocating target address information to the home terminal and from the proxy image capturing device based on a plurality of pieces of address information to be allocated respectively includes: if the first image acquisition equipment is not communicated with the video monitoring management platform, acquiring a group of address information from a plurality of groups of address information to be allocated as target address information of a local terminal; and aiming at each slave proxy image acquisition device, if the slave proxy image acquisition device is not communicated with the video monitoring management platform, acquiring a group of address information from the rest groups of address information to be distributed, generating a heartbeat packet according to the group of address information and a second IP address of the slave proxy image acquisition device, and sending the heartbeat packet to the local area network so that the slave proxy image acquisition device acquires the heartbeat packet from the local area network and acquires target address information distributed to the slave proxy image acquisition device based on the heartbeat packet.
In this embodiment, the first image capturing device 102 serving as a master proxy image capturing device may allocate a plurality of sets of to-be-allocated address information, which is obtained based on the random algorithm and the ARP protocol and does not conflict with the first IP address, to each slave proxy image capturing device, that is, the first image capturing device 102 may establish communication between the master proxy image capturing device and an image capturing device, which is not in communication with the video monitoring management platform 104, of the slave proxy image capturing devices and establish communication with the video monitoring management platform 104 in a manner of allocating target address information. Because the first image capturing device 102 serving as the master agent image capturing device may not establish communication with the video monitoring management platform 104, the first image capturing device 102 may first detect whether the local terminal is connected to the video monitoring management platform 104, and if not, the first image capturing device 102 may obtain a group of address information from a plurality of groups of address information to be allocated as target address information of the local terminal, thereby establishing connection between the first image capturing device 102 and the video monitoring management platform 104; after the first image capturing device 102 determines that the local terminal and the video surveillance management platform 104 can communicate, the detection of whether to establish communication with the video surveillance management platform 104 may be performed for each slave agent image capture device, and if the first image capture device 102 detects that a slave agent image capture device is not in communication with the video surveillance management platform 104, the first image capturing device 102 may obtain a set of address information from the remaining set of address information to be assigned, generate a heartbeat packet based on the set of address information and the second IP address of the slave image capturing device, and sends out the heartbeat packet to the middle year of the local area network, so that the slave agent image acquisition device can detect and receive the heartbeat packet from the local area network, therefore, the slave proxy image acquisition device can obtain the target address information allocated to the slave proxy image acquisition device based on the heartbeat packet and modify the corresponding address information of the slave proxy image acquisition device based on the target address information.
For example, as shown in fig. 4, fig. 4 is a schematic flowchart of a network distribution step of a master agent image capturing device in an embodiment. The first image capturing device 102 and the second image capturing device 106 may both be cameras, and when the first image capturing device 102 is used as a master proxy image capturing device, the first image capturing device 102 may first determine whether the master proxy camera is connected to the VMS, and if not, the first image capturing device 102 uses a random algorithm to obtain information, such as a non-conflicting IP address and a subnet mask, that is connected to the VMS by detecting an ARP protocol, as an IP address and a subnet mask of the local computer. When the first image acquisition device 102 determines that the local terminal establishes communication with the video monitoring management platform 104, the first image acquisition device 102 may use a random algorithm, obtain information such as a non-conflicting IP address and a subnet mask communicated with the VMS through ARP protocol detection, and sequentially allocate information such as a non-conflicting IP address to the slave proxy cameras that are not communicated with the VMS on the local area network. Specifically, the first image capturing device 102 may send a multicast packet of a private protocol to the local area network, modify information such as an IP address of the slave proxy camera, and after the modification is completed, the first image capturing device 102 may remove the modified slave proxy camera from the camera list. The first image capturing device 102 may detect whether there is a slave proxy camera that is not connected to the video monitoring management platform 104 by sending a multicast heartbeat packet to the local area network at intervals, if yes, the first image capturing device 102 may continue to execute a process of allocating address information to the slave proxy camera, and when the first image capturing device 102 detects that the master proxy image capturing device and each slave proxy image capturing device establish communication with the video monitoring management platform 104, the process of allocating address information may be stopped.
Through this embodiment, the first image capturing device 102 may allocate address information to the home terminal and the slave agent image capturing device when serving as a master image capturing device, and establish communication with the video monitoring management platform 104, thereby achieving an effect of communication across network segment devices.
In an embodiment, after acquiring the first IP address of the video monitoring management platform based on the multicast detection packet, the method further includes: if the address distribution process to be distributed executed by the last multicast detection message based on the video monitoring management platform is not finished, detecting whether a first IP address in the last multicast detection message is in the same network segment with a first IP address contained in the multicast detection message; if not, stopping the distribution process of the address to be distributed based on the previous multicast detection message, and executing the step of acquiring the MAC address of the first image acquisition equipment and the MAC addresses of a plurality of second image acquisition equipment in the local area network based on the first IP address of the multicast detection message.
In this embodiment, the multicast detection message sent by the video monitoring management platform 104 may have a process of sending multiple times, and the multicast detection message sent each time may be determined based on the current network segment where the video monitoring management platform 104 is located, so that the process of modifying the IP address of the image acquisition device in the local area network may also include multiple times. When the first image capturing device 102 receives a multicast detection packet, the first image capturing device 102 may detect whether an address allocation procedure to be allocated executed based on a previous multicast detection packet of the video monitoring management platform 104 is finished, if not, the first image capturing device 102 may detect whether a first IP address of the video monitoring management platform 104 in the previous multicast detection packet is in the same network segment as a first IP address included in the multicast detection packet received this time, if not, the first image capturing device 102 may stop the address allocation procedure to be allocated based on the previous multicast detection packet, and then start to execute a step of acquiring a MAC address of the first image capturing device 102 and MAC addresses of a plurality of second image capturing devices 106 in the local area network based on the first IP address of the multicast detection packet received this time, thereby realizing address allocation.
In addition, in some embodiments, after detecting whether the first IP address in the previous multicast probe message is in the same network segment as the first IP address included in the multicast probe message, the method further includes: if so, ignoring the multicast detection message, and continuing to execute the address distribution flow to be distributed executed based on the previous multicast detection message. In this embodiment, if the first image capturing device 102 detects that the first IP address of the video monitoring management platform 104 in the previous multicast detection message is in the same network segment as the first IP address included in the multicast detection message received this time, the first image capturing device 102 may end the address allocation process of the multicast detection message received this time, and further continue to execute the address allocation process to be allocated executed based on the previous multicast detection message.
For example, the first image capturing device 102 may be a camera, and after the camera receives the ONVIF multicast detection packet and parses the IP address of the coded VMS from the packet, the camera may determine whether the previous process of modifying the IP address by the VMS is not completed, and if the previous process is not completed, if the previous process is in the same network segment as the previous IP address, the previous process of modifying the IP address is returned, otherwise, the previous process of modifying the IP address is interrupted, and the process of modifying the IP address is executed again.
Through the above embodiment, when detecting a plurality of multicast probe messages, the first image capturing device 102 may determine, through the network segment where the multicast probe message is located, the multicast probe message for address allocation and execute an address information allocation procedure based on the corresponding multicast probe message, thereby ensuring the validity of address allocation.
In one embodiment, before acquiring the MAC addresses of the plurality of second image capturing devices in the local area network, the method further includes: and monitoring all the other online image acquisition equipment in the local area network as a plurality of second image acquisition equipment.
In this embodiment, when the first image capturing device 102 detects a multicast detection packet sent by the video monitoring management platform 104, the MAC address of the local terminal and the MAC addresses of the plurality of second image capturing devices 106 in the local area network may be obtained. Wherein the plurality of second image capturing devices 106 may be devices in a local area network that meet set conditions. For example, the first image capturing device 102 may be a camera, and the camera may send a multicast packet of a private protocol to the lan, acquire all online cameras in the lan, and obtain a camera information list of the lan, including an IP address, an MAC address, and the like.
Through this embodiment, the first image capturing device 102 may acquire an online camera in the local area network as the plurality of second image capturing devices 106, so that an address allocation procedure may be performed, and communication across segment devices in the local area network may be further implemented.
In one embodiment, as shown in fig. 5, fig. 5 is a schematic flow chart of a network distribution method for cameras in another embodiment. The method comprises the following steps: the first image acquisition device 102 may be a camera, the camera may be started first, a monitoring ONVIF multicast port is opened, the video monitoring management platform 104 sends a standard ONVIF multicast detection message to the local area network, and the camera may analyze an IP address of the video monitoring management platform 104 from the ONVIF multicast detection message sent by the video monitoring management platform 104 after receiving the ONVIF multicast detection message; the camera may also determine whether the previous ONVIF multicast modification IP address flow of the video surveillance management platform 104 was completed, and if not, the camera detects whether the multicast modified IP address is in the same network segment as the previous video monitoring management platform 104ONVIF multicast modified IP address, if yes, returning, if the modified IP address is not the same network segment as the previous video monitoring management platform 104ONVIF multicast, the camera terminates the previous process of modifying the IP address by ONVIF multicast of the video monitoring management platform 104, starts the current process of modifying the IP address by ONVIF multicast of the video monitoring management platform 104, if the camera can also judge that the previous process of modifying the IP address by ONVIF multicast of the video monitoring management platform 104 is finished, the camera may also continue the process of this time the video surveillance management platform 104ONVIF multicasts the modified IP address, sending a multicast message of a private protocol to the local area network to acquire all online cameras of the local area network; finding out the camera with the maximum MAC address from all online cameras in the local area network as a master agent camera, and if the local terminal is the master agent camera, allocating an IP address to a slave agent camera except the local terminal as the master agent camera; if the home terminal is not the master agent camera, the home terminal may wait for the master agent camera to assign an IP address, thereby establishing communication with the video surveillance management platform 104.
It should be noted that, in this embodiment, the ONVIF protocol multicast detection that uses the universal open-source standard is supported as long as the manufacturer follows the standard protocol, and at present, video monitoring management platforms (VMS) or hard disk video recorders of almost all manufacturers in the market support the protocol, and can seamlessly access devices of different manufacturers. The cameras of the local area network automatically detect the number of the cameras of the local area network, if more than 1 camera exists, a main agent camera is selected according to rules to carry out uniform IP address distribution, and the cameras are not independent individuals. When the local area network has only 1 camera, the camera allocates the IP address by itself, which has the advantages of reducing the IP conflict ARP detection packet of the local area network and reducing the IP address conflict generated when a plurality of cameras allocate the IP addresses at the same time. And when the camera detects the allocated IP address, the ARP protocol and PING test are used to detect the connectivity, so as to ensure that the allocated IP address can be communicated with the VMS unless the IP address of the local area network is occupied. The camera private protocol uses multicast and unicast modes for communication, and data communication of a local area network can be reduced. In addition, the communication between the cameras can use self-developed encryption and decryption algorithms to ensure the safety of data transmission.
By the embodiment, the image acquisition equipment used for allocating the address capable of communicating with the management platform is selected from the plurality of image acquisition equipment and the address is allocated, so that the effect of enabling the equipment across network segments to communicate is achieved, the VMS is enabled to be in network communication with the camera, and a very simple matter is achieved. The operational complexity of communicating the VMS with the camera is greatly reduced.
