Description

Automatic networking method and device of video monitoring equipment
Technical Field
The invention belongs to the technical field of video monitoring networking, and particularly relates to an automatic networking method and device of video monitoring equipment.
Background
Video monitoring is an important component of a safety precaution system, and is widely applied to many occasions due to intuition, accuracy, timeliness and rich information content. In recent years, with the rapid development of computers, networks, image processing and transmission technologies, the popularization trend of video monitoring is more and more obvious.
With the popularization of video monitoring, the installation workload of video monitoring equipment is relatively large. Most of civil video monitoring systems adopt a plurality of network cameras IPC as front-end image acquisition equipment, a plurality of network video recorders NVR as rear-end management equipment, and one NVR manages dozens of IPC or even hundreds of IPC.
Therefore, for a slightly complex network, the video monitoring system has a huge opening or maintenance workload, and engineering maintenance personnel need to manage and configure each NVR and IPC, so that the work task is heavy, and the efficiency is low.
Some methods for automatically detecting connection are also proposed in the prior art, for example, the NVR detects an IPC in a network through ONVIF, after receiving the broadcast message, an unconnected IPC sends a connection request to the NVR, and the NVR acquires configuration information of the IPC through the received connection request and establishes connection with the IPC through the configuration information and performs communication.
However, although the above technical solution realizes the function of NVR automatically detecting and connecting IPC, when multiple NVRs and multiple IPCs exist in the network, the designated pair cannot be automatically added.
In another prior art solution, a preset policy is used to implement IPC networking to a specified NVR, however, if the preset policy is used to implement networking, the preset policy may cause that the accessed monitoring device is only managed by the management device accessed to the same network or the management device on the previous layer, and cannot be managed by other management devices. When the management device of the current layer is disconnected or the spare part is replaced, the monitoring device can be automatically added to the management device of the previous layer. Therefore, due to the existence of the preset strategy, the management of the monitoring equipment is confused.

Detailed Description
The technical solutions of the present invention are further described in detail below with reference to the drawings and examples, which should not be construed as limiting the present invention.
The invention is applied to a video monitoring system under complex networking, the video monitoring system comprises a plurality of management devices and a plurality of monitoring devices, and the management devices and the monitoring devices are networked through a network such as a switch. The management device can be a hard disk video recorder (NVR/DVR) or a all-in-one machine in a network, and the monitoring device can be a network camera IPC or an encoder.
An embodiment of the present invention, as shown in fig. 1, is an automatic networking method for a video monitoring device, applied to a management device in a video monitoring system, including:
step S1, searching all monitoring devices and management devices in the network, and performing group configuration on all the searched monitoring devices and management devices.
The equipment of the video monitoring system supports the ONVIF protocol, while most of the management equipment and the monitoring equipment of the video monitoring system are in the same local area network, and all the monitoring equipment and the management equipment in the network can be searched through the ONVIF protocol. The embodiment does not consider the networking situation of the monitoring device and the management device in different local area networks.
As shown in FIG. 2, assuming that the user logs in NVR1, NVR1 searches for all devices in the network, such as NVR 1-NVR 3, IPC 1-IPC 7. The embodiment is described by taking fig. 2 as an example, and is not limited to the specific number of devices in the network.
Then the user performs grouping configuration on NVR1, for example, IPC1, IPC3 and NVR1 are located in the same Group, and the Group number is Group 1; IPC4, IPC5 and NVR2 are in the same Group, and the Group number is Group 2; IPC2, IPC6, IPC7 and NVR3 are in the same Group, and the Group number is Group 3.
All management devices and monitoring devices are grouped on the NVR1, and the grouping may be performed manually, and a specific sub-network is often grouped according to a preset network topology, which is not described herein again.
Step S2, sending a grouping configuration message to all the monitoring devices and the management devices, respectively, where the grouping configuration message carries the grouping number and the device identifier of the receiving device.
In this embodiment, after the configuration is completed, the management device for configuration sends the grouping configuration message to each monitoring device and each management device which are searched. The sending may be broadcast sending, or sending according to the MAC address of the receiving device, which is not limited in the present invention.
The packet number and device representation of the receiving device are carried in the sent packet configuration message, the packet number is the number of the packet where the receiving device is located, and the receiving device is the device for receiving the packet configuration message. The device identifier in this embodiment is generally a device serial number or a MAC address, and may also be a name of a device, and the like, as long as the identifier is unique in a network, and the following embodiment takes the device serial number as an example for description.
Still taking fig. 2 as an example, after the NVR1 configures the packet, it needs to send a packet configuration message to NVR2, NVR3, IPC1 to IPC7, and NVR1 itself has a packet configuration message.
If the packet configuration message is sent to the NVR2 and the NVR2 is a receiving device, the packet configuration message carries the device sequence number of the NVR2 and the packet number Group2 where the NVR is located.
Similarly, NVR1 also sends grouping configuration messages to NVR3, IPCs 1 to IPCs 7, which are not described herein.
Step S3, receiving the grouping configuration message, when determining that the self is the receiving device according to the device identification carried in the grouping configuration message, taking the grouping number carried in the grouping configuration message as the grouping number of the self, automatically searching the monitoring device in the same group in the network, and adding the monitoring device in the same group to the idle channel.
As a management device, a packet configuration message is received. For example, NVR2 may receive the distribution configuration message sent by NVR1, and NVR1 itself may receive the grouping configuration message after grouping. After receiving the grouping configuration message, firstly, whether the grouping configuration message is sent to the user can be judged according to the equipment identifier carried in the grouping configuration message, the judgment is carried out through the equipment identifier carried in the grouping configuration message, and if the grouping configuration message is consistent with the equipment identifier of the user, the grouping configuration message sent to the user is judged, so that the processing is carried out. If not, the message is not the packet configuration message sent to the self and is not processed.
When processing, firstly, the packet number carried in the packet configuration message is used as the packet number of the packet configuration message. In this case, the following processing modes are included:
1. if the packet number of the added channel is consistent with the packet number of the added channel, keeping the added channels unchanged, otherwise deleting the added channels.
2. Checking whether the channel of the user is full, and if the channel of the user is full, not processing the channel; and if the adding is not full, searching for the monitoring equipment to be added according to a preset time interval.
For example, upon receiving the packet configuration message, the NVR2 takes Group2 as its own packet number, and needs to change to Group2 regardless of the previous packet number of its own packet.
Then, the own channel is checked, and if two channels are added and the two added channels are not grouped in the same Group as Group2, the two channels are deleted at the moment, the configuration is carried out again, and if the two added channels are consistent, the two added channels are reserved.
And then, when the channel is not full, searching the monitoring equipment according to a preset time interval (for example, 60s), wherein the searching is carried out by adopting an ONVIF protocol, the sent automatic discovery message carries a packet number, and the monitoring equipment is discovered by adopting the ONVIF protocol to be a relatively mature technology, which is not described again here.
The management device of the embodiment automatically searches for the monitoring devices in the same group in the network, and adds the monitoring devices in the same group to an idle channel, and the management device has two implementation modes.
In embodiment 1, the management device sends an auto discovery packet to search for the monitoring devices in the same group in the network, and adds the monitoring devices in the same group to an idle channel after receiving a response from the monitoring devices in the same group.
The monitoring device receiving the NVR2 auto discovery message first needs to see whether the auto discovery message is consistent with its own packet number, and if so, responds, and if not, does not respond. Assuming that the IPC4 responds, the response message will carry the Group number Group2, and after receiving the response message, the NVR2 determines whether the Group number carried in the response message is consistent with the Group number of the response message, and if all the Group numbers are Group2, adds the IPC4 to the idle channel.
Embodiment 2 receives an auto discovery packet sent by the monitoring devices in the same group in the network, responds, and adds the monitoring devices in the same group to an idle channel.
For example, receiving the IPC4 to send an auto discovery packet, where the auto discovery packet carries a packet number, and is Group2, first, whether the auto discovery packet is consistent with the packet number of the auto discovery packet, if so, responding is performed, and if not, no response is performed. NVR2 responds by carrying the packet number Group2 in the response message and adds IPC4 to the idle channel.
The foregoing embodiment is described by taking a management device as an example, and as shown in fig. 3, a further embodiment of the present invention is an automatic networking method for a video monitoring device, which is applied to a monitoring device in a video monitoring system, and includes:
receiving a grouping configuration message, and when determining that the grouping configuration message is a receiving device according to a device identifier carried in the grouping configuration message, taking a grouping number carried in the grouping configuration message as a grouping number of the grouping configuration message;
and automatically searching the management equipment in the same group in the network, and adding the management equipment to the management equipment in the same group.
Taking IPC3 as an example, after receiving the packet configuration message sent by NVR1, IPC3 determines whether it is the receiving device or not according to the device sequence number carried in the packet configuration message, and if so, takes the packet number carried in the packet configuration message as the packet number of itself. If the Group number carried in the Group configuration message sent by NVR1 is Group1, IPC3 sets the Group number where IPC is located as Group 1.
It should be noted that if the original Group number of IPC1 is not Group1, the current external connection is disconnected, no longer managed by any NVR, and then automatic discovery is started.
That is, the receiving the grouping configuration message, and when determining that the self is the receiving device according to the device identifier carried in the grouping configuration message, taking the grouping number carried in the grouping configuration message as the grouping number where the self is located, further includes:
if the original packet number of the mobile terminal is not consistent with the packet number of the mobile terminal, the external connection is disconnected.
Similarly, the automatic discovery process has two modes, one mode is that an automatic discovery message is sent to inform the management equipment in the same group in the network and is added to the management equipment in the same group; and the other is to receive the automatic discovery message sent by the same group of management equipment in the network, respond and add the message to the same group of management equipment. Regarding the process of auto discovery, IPC3 is added to NVR1 after discovering NVR1, which has been described in detail above. And will not be described in detail herein.
If IPC has been added by NVR of the same group, no more auto discovery messages are sent and added.
In another embodiment of the present invention, the packet configuration message further carries a special identifier, and the receiving device identifies the special identifier carried by the packet configuration message when receiving the packet configuration message, and processes the packet configuration message if the special identifier is carried by the receiving device, otherwise discards the packet configuration message.
The special identifier is also carried in the grouping configuration message, so that the grouping configuration message is favorably and correctly identified, the condition that misoperation is caused by other factors is avoided, and the receiving equipment only processes the grouping configuration message after identifying the special identifier.
The invention provides a method for grouping and configuring NVR and IPC in a local area network, realizing automatic networking according to a grouping number through NVR automatic search and IPC active notification, and realizing automatic networking by only grouping and configuring the same group number to the spare part NVR when replacing the spare part in the network. Similarly, the same is true when the IPC performs replacement of spare parts. The method can greatly improve the working efficiency of engineering maintenance personnel in the process of monitoring system opening or maintenance.
