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 general idea of the invention is to perform equipment management facing to user requirements, the user only needs to provide own original requirements, and the video monitoring system completes automatic management of the equipment according to actual equipment conditions through analysis of the user requirements.
As shown in fig. 1, a device management method facing user requirements includes:
step S1, in-network equipment discovery is carried out in a pre-established equipment network, and equipment is added;
step S2, traversing the added equipment, connecting the equipment and acquiring equipment information;
step S3, acquiring device capability parameters from the devices of each device type according to the device type in the acquired device information;
step S4, receiving user requirements submitted by a user, analyzing according to the user requirements and the acquired equipment capacity parameters, and generating configuration information of each equipment;
and step S5, issuing configuration information to each device to complete the configuration of each device.
Specifically, when a video monitoring system needs to be deployed, a user needs to connect devices (e.g., NVR and IPC) in a network to a network, such as a lan, to ensure that the devices are accessible to each other. It should be noted that this embodiment mainly addresses the networking situation where NVRs and IPCs are mutually reachable, and it is not considered in the scope of the present invention that when an IPC is accessed to a certain NVR, another NVR cannot access the IPC from the network layer.
The technical scheme of the invention is provided with a management device for realizing the method. The management device operates in a device network, such as a PC that is always connected to the network, or an NVR in the network, as long as all monitoring devices in the network can be accessed.
As shown in fig. 2, the technical solution of the present invention completes system construction through the above-mentioned management device, that is, completes the work of steps S1-S3, and is described in detail below:
f101, performing in-network device discovery through a standard protocol (such as an ONVIF protocol).
Regarding automatic discovery of NETWORK devices, a common method is to discover devices through a discovery process of ONVIF, and the discovery process has two basic ways, namely, an NVT device (NETWORK VIDEO server) sends a hello message, and an NVC device (NETWORK VIDEO CLIENT) receives the hello message and then responds; and secondly, the NVC equipment sends a Probe/Resolve message, and the NVT responds to the Probe Match/Resolve response message after receiving the Probe/Resolve message. For example, in this embodiment, the management device is an NVC, and the monitoring device (NVR/IPC) is an NVT, which can implement discovery of devices, and the implementation of discovery of devices in a network is a relatively mature technology, and is not described here again.
F102, finding and obtaining the device address information.
In the auto discovery message of the network device, the address information of the device is carried, and the monitoring device (NVR/IPC) informs the management device of the address information of the device through a self-discovery response message.
F103, traversing the added equipment, and connecting the equipment.
After discovering the monitoring device, the management device initiates a connection to the monitoring device, and establishes a connection with the monitoring device.
F104, the device returns a response OK.
And the monitoring equipment receives the connection request of the management equipment, returns a response OK message and completes equipment connection.
F105, acquiring the equipment information.
After the management device establishes connection with the monitoring device, the management device can send information to the monitoring device to acquire device information.
F106, returning the device information such as the device type, the unique device identification and the like by the device.
The monitoring equipment responds and sends the equipment information such as the equipment type, the equipment unique identification and the like of the monitoring equipment to the management equipment.
And F107, recording the equipment information and judging the type.
The management device obtains the device information of the monitoring device, records the device information, judges the type of the monitoring device, and distinguishes the type of the monitoring device, namely distinguishes which devices are NVR and IPC.
And F108, traversing all the devices and acquiring the capability parameters of the devices.
The management device further obtains capability parameters of the monitoring device, and the method specifically includes:
and sending a message to the NVR equipment to acquire the capacity parameters of the NVR, wherein the capacity parameters comprise the upper limit of the connection number, the upper limit of the storage space, the used connection number, the information of each channel, a corresponding storage plan and the like.
And sending a message to the IPC equipment to acquire the IPC capability parameters including information of resolution, coding capability and the like.
F109, maintaining the device connection, refreshing the connection state and the device state.
The management equipment also sends keep-alive information, maintains the equipment connection, refreshes the connection state and records the state of the monitoring equipment.
Through the steps, the system construction is completed in the embodiment, and it is easy to understand that all monitoring devices in the video monitoring system are applicable to the technical scheme of the present invention, and the embodiment only exemplifies some monitoring devices, is not limited to the monitoring devices, and may also include, for example, a digital hard disk video recorder DVR, a codec, and the like.
The following describes a specific service configuration through a specific embodiment, that is, steps S4 and S5 of the technical solution of the present invention are described. Since the functions of the video monitoring system are very rich, for convenience, in the following description, part of the functions are taken as examples (e.g., storing, forwarding, etc.), the actual video monitoring system further has other functions (e.g., alarm message storing and reporting, etc.), the processing methods are basically similar, and details are not repeated here.
Embodiment one, video recording plan configuration.
When configuring a video plan, a user needs to inform management equipment of a video storage requirement, the management equipment receives the configuration requirement submitted by the user, records the user requirement, analyzes and generates configuration information of each equipment, and issues the configuration information to each equipment to complete the configuration of each equipment.
Specifically, as shown in fig. 3, the method includes:
f301, submitting video storage requirements including definition requirements, retention time requirements and the like by a user.
F302, the management equipment records and analyzes the video storage requirements submitted by the user, and generates configuration information of each equipment. For example, code stream configuration information of the IPC device is generated, channel configuration information of the NVR device is generated, and storage plan configuration information is generated.
F303, the management equipment sends the equipment code stream to be configured to the IPC corresponding to the video storage requirement, and the configuration of the IPC equipment is completed.
F304, the management device issues the device channel configuration to the NVR, and the channel configuration of the NVR device is completed.
F305, the NVR equipment and the IPC equipment establish equipment connection to realize communication.
F306, the management device issues the storage plan configuration to the NVR, and the storage plan configuration of the NVR device is completed.
And F307, acquiring video data for storage by the NVR equipment and the IPC equipment according to the storage plan.
It should be noted that, specifically, how to analyze and calculate the configuration information such as the corresponding video storage plan according to the user requirement is described below by way of example, but the present invention is only a feasible manner, and the present invention is not limited to how to analyze and calculate the configuration information according to the user requirement.
For example, after the management device obtains the user requirement, the user storage definition requirement and the time duration requirement can be known.
When the definition requirement is one of smooth, balanced and high-definition, the management equipment analyzes the definition requirement and acquires the corresponding IPC coding parameters. For example, when the definition requirement is balance among the user requirements, the coding rate of 1Mbps corresponding to the balance is obtained. And then, issuing IPC code configuration to the IPC to complete the IPC configuration.
When configuring the NVR, an appropriate NVR is selected. When the management device discovers the device, the management device already has a list of all NVRs and also acquires the capability parameters of the NVRs. Therefore, the allocated storage (Sused) and the residual storage space (Sidle) of each NVR can be calculated, and the NVR with the largest residual storage space can be selected to manage the IPC of the user.
And after the NVR is selected, modifying the channel configuration of the NVR, and adding IPC of a user corresponding to one channel. And then, according to the reservation time requirement in the user requirement, calculating a corresponding NVR channel storage plan, issuing the NVR channel storage plan, and completing the configuration of the NVR.
It should be noted that Sused corresponds to allocated storage, and Sused is the sum of allocated storage for each channel. For example, if the unit adopts GB, if the channel D1 does not enable storage, then Sused1 is 0 GB; channel D2 has the storage plan enabled, has a storage duration of X (days), and has a code rate of M (mbps), then Sused2 ═ M × X3600 × 24/8/1024; channel D3 enabled storage planning, and compared to D2, was only stored for 8 hours during the day, with the rest being the same, then Sused3 — Sused2 — 8/24; by analogy, the allocated storage of each channel can be obtained.
Finally, Sused (Sused1+ Sused2+ … + Sused n), n is the number of channels.
The above is only for convenience of understanding, and the practical application also considers more demand situations by adopting a simplified calculation method. For example, when the storage space is insufficient, the channel storage is reallocated, and the whole IPC is reallocated according to the required storage resources of all IPCs; or one IPC needs too large storage resources and needs to be dispersed to a plurality of NVRs to provide the storage resources, for example, 1 week of video records are originally stored, the IPC video records are divided into 7 NVRs, and each NVR stores 1 day of IPC video records; or the design of increasing weight, when the storage space is not enough, the partial channels are preferentially ensured, or the equal proportion of all the channels is preferentially ensured, the video recording at the early time is lost, and the like.
It should be noted that, regarding selection of NVRs, channel configuration, and storage plan configuration, there may be configurations such as storage policies (all day/movement) that all cause adjustment of calculation formulas and flows, and details are not described here. The technical scheme of the invention is not limited to how to generate the configuration plan according to the analysis of user requirements, and when the NVR is selected, the selection can be carried out according to the NVR video pressure condition, and the current video plan is allocated to the NVR with the lightest pressure; or according to the priority, the NVRs with the higher priority are selected first until the storage resources of one NVR are occupied, and then the next NVR is selected.
In the above configuration process, the user only needs to do one thing, namely, fill in the video recording requirement of the IPC of interest. The storage, including which NVR is present, is not enough space, and so on, all need not be considered. The embodiment greatly improves the function experience and can fully utilize the storage capacity of each device.
Embodiment two, dynamically adjusting the configuration.
The management equipment of the technical scheme not only can complete the initial configuration after the system is built, but also has a lot of function enhancement in the subsequent use, and the deep explanation is made through code stream forwarding and exception handling.
The embodiment of code stream forwarding comprises the following steps: a single IPC has a limited number of simultaneous accesses, for example, at most 3 people can simultaneously view the live condition, and in some cases, the number of people is smaller. Therefore, in practical situations, the IPC live scene can be viewed through the NVR by using the relay function of the NVR, and at the moment, the IPC live scene can be viewed by more people at the same time, for example, 16 people at the same time. Even so, however, the forwarding capability of an NVR is limited. The embodiment fully utilizes the capacity of a plurality of NVRs in the whole system to achieve dynamic adjustment of the channel configuration of the NVRs and achieve maximization of the capacity of watching people by a single IPC.
As shown in fig. 4, the specific implementation process of code stream forwarding is as follows:
f401, the management device acquires an IPC live request initiated by the user.
F402, analyzing the live request by the management device.
After analyzing the live request, there are the following cases:
in the first case, if the number of requests is very small, the IPC has not been added to any NVR, and the code stream request service can also be provided, the code stream address is directly provided, as shown in step F403, by directly requesting the IPC. The code stream address is an RTSP or RTMP address, which is not described in detail below.
In the second case, if IPC has been added to NVR and NVR can also provide the requested service, as shown in steps F404, F405. F404, acquiring NVRs capable of providing services, for example, acquiring an added NVR list, comparing forwarding capabilities of remaining code streams, and returning an NVR with the maximum capability; f405, obtaining the code stream address of the IPC corresponding to the user request.
In the third case, if the added NVR can no longer provide the requested service, as shown in steps F406, F407, and F408. F406, selecting a proper NVR for adding, for example, acquiring other NVR lists, firstly screening the NVRs with the number of channels not being full, then comparing the forwarding capacities of the remaining code streams, and returning the NVR with the maximum capacity; f407, modifying the channel configuration and adding IPC; f407, acquiring the code stream address of the IPC corresponding to the user request.
And finally, F409, the management equipment returns the code stream information to the user for playing.
The above only enumerates a simpler analysis method, and actually, the function of deleting the bound channel can also be taken into account, so that more reasonable allocation of resources can be realized. For example, for NVRs whose channels are full but have low access traffic, a part of the channels may be replaced with those with high access traffic; when the IPC capability is full and can not be added by more NVRs, the NVR with the largest connection capability is selected to replace the NVR with the worst capability in the NVRs currently connected with the IPC. Many similar further optimizations can be achieved based on the architecture of the technical scheme of the present invention, which are not described herein again.
Examples of exception handling: taking the storage function abnormality of a certain NVR as an example, once there is an equipment abnormality, the other equipment is started immediately, so as to ensure the continuous normal operation of the service. The specific implementation process is as follows:
the management equipment acquires the running state of each equipment, and if a certain NVR is found to be offline or an abnormal storage alarm is received, the IPC associated with the NVR and a corresponding storage plan are acquired;
acquiring an online NVR equipment list;
and selecting an idle NVR, configuring a storage plan, and configuring IPC (IPC) associated with the abnormal NVR and the corresponding storage plan to the selected NVR.
Acquiring the running state of the equipment at the management equipment, and checking storage plans of all the equipment if finding that a certain NVR is recovered on line or the storage function is recovered;
and if the storage plan is found to be duplicated, refreshing the storage plans of all the NVR devices, removing the duplicated part, and if the storage plan is not duplicated, operating normally.
Embodiment three, video playback configuration.
In the second embodiment, IPC videos may be stored in multiple NVRs, and during playback, overall management is required, as shown in fig. 5, the method includes the following steps:
f501, the management equipment acquires an IPC playback request initiated by a user;
f502, the management equipment acquires the storage time period of the IPC on all NVRs;
f503, merging the time periods, and marking the video sources of the time periods;
f504, generating a play list, wherein the play list comprises code stream addresses and time periods;
and F505, playing the video according to the play list and presenting the video to the user.
According to the technical scheme of the invention, a user does not need to consider negative influences brought by the requirement change, such as: a user wants to store one IPC more, originally needs to check the spare capacity condition (storage and connection number) of each NVR, selects a corresponding NVR, configures the NVR and adds the equipment; the user wants to lengthen the storage time of an IPC, originally needs to find the NVR corresponding to the IPC and modify the configuration of the IPC, is more troublesome when the space is insufficient, and needs to find out which space is sufficient for other NVRs, then adjust the connection layout of the IPC and modify the storage plan configuration of the NVR of the other party. Through the technical scheme of the invention, the IPC is directly added into the system to inform the system of the corresponding storage requirement without worrying about all the situations. In addition, when an abnormal condition occurs, for example, one NVR fails to provide a service normally, the original user also needs to migrate the relevant configuration to the new NVR, and there is no need to worry about this technical solution, and such a problem can be automatically maintained in this technical solution.
Corresponding to the foregoing method, an embodiment of a device management apparatus facing user requirements is provided herein, where the apparatus management apparatus is used for device management in a video monitoring system, where the video monitoring system includes a pre-established device network and a management device that is intercommunicated with each device in the device network, and the device management apparatus facing user requirements is applied to the management device, and includes:
