Description

Uplink bandwidth allocation method, device and system

Technical Field

The present application relates to the field of computer technologies, and in particular, to a method, an apparatus, and a system for allocating uplink bandwidth.

Background

In the prior art, a typical video surveillance system, as shown in fig. 1, may include a back-end device, a router, and at least one front-end surveillance device. The backend device generally includes a computer, such as a personal computer, or a Digital Video Recorder (DVR), a Network Video Recorder (NVR), and the like; front-end monitoring devices typically include a camera.

Based on the system architecture shown in fig. 1, on one hand, the front-end monitoring device may send monitoring data (such as images or videos) to the router, so that the router uploads the monitoring data to a data receiver in the public network; on the other hand, the front-end monitoring device can directly send the monitoring data to the back-end device for processing based on the connection with the back-end device. For convenience of description, an uplink bandwidth occupied by the monitoring data sent by the router to the public network is hereinafter referred to as an uplink bandwidth.

Different front-end monitoring devices respectively adopt different data transmission protocols, so that the different front-end monitoring devices respectively compete for different uplink bandwidths. For example, in a data transmission protocol adopted by some front-end monitoring devices, the number of times of allowing access to the public network within a specified unit time is large, and thus, the uplink bandwidth contended by the front-end monitoring device may be large; conversely, the contended upstream bandwidth may be smaller.

For a front-end monitoring device with a small upstream bandwidth, in some scenarios, the monitoring data sent by the front-end monitoring device may need to be sent to the public network at a larger transmission rate. For example, if the front-end monitoring device monitors an urgent event (such as a human intrusion event) and the video stream corresponding to the event (the video stream is a kind of monitoring data) has a high bit rate, in such a case, it may be necessary to transmit the video stream to the public network in real time at a high transmission rate, i.e., the video stream needs to occupy a large uplink bandwidth. However, according to the prior art, since the uplink bandwidth contended by the front-end monitoring device is small, the video stream can only be sent after waiting for the front-end monitoring device to contend for a sufficient uplink bandwidth, or the video stream can only be sent after being converted into a low bit rate.

For the front-end monitoring device competing for the larger uplink bandwidth, the monitoring data sent by the front-end monitoring device may not need the larger uplink bandwidth because the data volume is smaller, which is equivalent to waste of the uplink bandwidth.

Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.

Example 1

The embodiment 1 of the present application provides an uplink bandwidth allocation method, which is used to solve a problem that an uplink bandwidth contended by a front-end monitoring device is not matched with an uplink bandwidth required by monitoring data from the front-end monitoring device.

The execution subject of the method may be, but is not limited to, at least one of NVR, DVR, router, and other devices that can be configured to execute the method provided by the embodiments of the present application.

For the sake of clear description of the method provided in embodiment 1 of the present application, the following takes NVR as an example of the main implementation of the method, and details of the method provided in the embodiment of the present application are described below. It will be understood by those skilled in the art that NVR, the subject of which is the method, is merely an exemplary illustration and should not be construed as a limitation of the method.

Please refer to fig. 2a in the description, which is a schematic view of an application scenario of an uplink bandwidth allocation method according to an embodiment of the present application. The application scenario includes at least two front-end monitoring devices, and includes at least one NVR and one router. The NVR and each front-end monitoring device are connected; connection is established between each front-end monitoring device and the router; a connection is also established between the NVR and the router. The specific connection mode includes a wired connection and/or a wireless connection. Wireless connections may include, for example and without limitation: Wireless-Fidelity (Wi-Fi) connections, and the like.

Based on the connection established between the NVR and each front-end monitoring device, each front-end monitoring device can send monitoring data to the NVR; the NVR may store and parse the received monitoring data. Based on the connection established between each front-end monitoring device and the router, each front-end monitoring device can send the monitoring data to the router, so that the router sends the monitoring data to the public network, such as the cloud device sent to the public network for storage, and the like.

Based on the scenario shown in fig. 2a, please refer to fig. 2b of the specification further. Fig. 2b in the description shows a flowchart of a specific implementation of the uplink bandwidth allocation method provided in the embodiment of the present application, and as shown in fig. 2b, the method mainly includes the following steps:

step 21, determining event types corresponding to each monitoring data to be sent by utilizing the uplink bandwidth by the NVR;

in the scenario shown in fig. 2a, each piece of monitoring data to be sent by using the uplink bandwidth may be, for example, monitoring data sent by each front-end monitoring device to different channels (e.g., serial ports) of the NVR.

In the scenario shown in fig. 2a, for the same monitoring data x collected by a certain front-end monitoring device (assumed to be the front-end monitoring device 1), on one hand, the front-end monitoring device 1 sends the monitoring data x to NVR; on the other hand, the monitoring data x is sent to the router for subsequent sending to the public network by using the uplink bandwidth. The monitoring data x is one of the monitoring data to be transmitted by using the uplink bandwidth.

The front-end monitoring device described in the embodiment of the present application may include, but is not limited to, at least one of the following functions:

the camera shooting function, based on which the front-end monitoring equipment can acquire images (including infrared images) or videos, and the acquired images or videos can be used as monitoring data;

audio acquisition function-based on this function, the front-end monitoring device can sample the sound waves and digitize the sampled sound waves into corresponding audio data, which can also be used as monitoring data.

What kind of functions each front-end monitoring device shown in fig. 2a has specifically, what kind of monitoring data will be generated, may depend on actual needs, and this is not limited in this embodiment of the present application. For convenience of description, the method provided by the embodiment of the present application is introduced by taking the example that the front-end monitoring device has a camera function, and the monitoring data is video data.

When the monitoring data is video data, the NVR may determine event types corresponding to the video data to be transmitted using the uplink bandwidth by performing step 21. The event type refers to a type of an event occurring in video data obtained by a camera through shooting, and includes, for example: intrusion detection, legacy detection, motion detection, entry of a particular object, and the like.

A brief description of how to determine the type of event from the video data follows.

Intrusion detection refers to performing image processing, pattern recognition and the like on image frames acquired by a camera (acquired in a scanning mode), judging whether behaviors of target objects in the image frames meet preset intrusion conditions, and if yes, judging that an event of an intrusion detection type occurs. Intrusion detection may generally include zone intrusion detection and tripwire intrusion detection.

The carry-over detection means that if image processing, pattern recognition and the like are carried out on image frames acquired by a camera, and the fact that the time length of placing a certain article (package and the like) in a monitored scene exceeds the time limit of allowing stay is determined, an event of the 'carry-over detection' type is judged to occur.

Motion detection, also commonly called Motion detection, is based on the principle that different image frames acquired by a camera are calculated and compared according to a certain algorithm, and when a person walks through a monitored scene to cause the content of the image frames to change, corresponding calculation and comparison results indicating that the person moves in the monitored scene are obtained, so that the occurrence of a Motion detection type event is judged.

The specific object entering means that if image processing, pattern recognition and the like are performed on an image frame acquired by a camera, and it is determined that a target object matched with a preset image feature (such as a face feature of a criminal) exists in a monitored scene, it is determined that an event of a "specific object entering" type occurs.

Since determining the type of the event according to the video data is a relatively mature prior art, it is not described herein in detail.

It should be noted that, when the monitoring data includes audio data in addition to the video data, the type of the event occurring in the monitoring data may also include a type of "baby cry", for example. In the embodiment of the application, whether the voiceprint features of the audio data contained in the monitoring data are consistent with the voiceprint features of the audio data extracted in advance according to the baby cry can be judged, and if so, the type of the event appearing in the monitoring data can be judged to be the baby cry.

And step 22, determining information representing the predicted occupancy rates of the uplink bandwidths of the monitoring data by the NVR according to the determined event types.

How the estimated occupancy rate of the uplink bandwidth is matched with the event type respectively corresponding to each monitoring data can be set according to actual requirements.

For example, in a home environment, a resident is most concerned about baby crying and intrusion behavior of a person entering the resident, and then two event types of 'baby crying' and 'intrusion detection' can be set to match with the higher estimated occupancy rate of the upstream bandwidth; in addition, setting event types such as "leave behind detection" matches lower upstream bandwidth occupancy. In the shopping environment of retail industries such as small supermarkets and the like, merchants are most concerned about whether guests enter the shops or whether people break into cashiers or warehouses, and then two event types of 'mobile detection' and 'intrusion detection' can be set to be matched with the higher estimated occupancy rate of the uplink bandwidth; in addition, setting event types such as "leave behind detection" matches lower upstream bandwidth occupancy.

In order to enable the NVR to conveniently and quickly determine the information representing the respective estimated uplink bandwidth occupancy rates of the monitoring data according to the determined event type, in the embodiment of the present application, a mapping relationship between different event types and the information representing the uplink bandwidth occupancy rates of the monitoring data may be preset, so that the mapping relationship is subsequently queried according to the determined event type, thereby determining the information representing the uplink bandwidth occupancy rates of the monitoring data.

The information characterizing the uplink bandwidth occupancy of the monitoring data may include, for example, one of the following information:

monitoring the predicted occupancy rate of the uplink bandwidth of the data;

monitoring the priority of the uplink bandwidth occupation of the data;

monitoring the uplink bandwidth occupation priority of the data, and allocating the uplink bandwidth based on the uplink bandwidth occupation priority.

When the information representing the uplink bandwidth occupancy rate of the monitoring data includes the estimated uplink bandwidth occupancy rate of the monitoring data, taking a home environment as an example, the preset mapping relationship between different event types and the information representing the uplink bandwidth occupancy rate of the monitoring data may be as shown in table 1:

table 1:

event type	Occupancy of upstream bandwidth
		Intrusion detection	40％
Carryover detection	5％
		Motion detection	5％
Object-specific entry	10％
		Baby crying	40％

By querying the table 1, the NVR can determine the uplink bandwidth matched with each event type according to the respective corresponding event type of each monitoring data to be transmitted by using the uplink bandwidth. For example, if the event type corresponding to the monitoring data to be transmitted by using the uplink bandwidth from the front-end monitoring device 1 is "intrusion detection", the uplink bandwidth occupancy rate corresponding to the event type may be determined to be 40% by referring to the table 1; if the event type corresponding to the monitoring data to be transmitted by using the uplink bandwidth from the front-end monitoring device 1 is "specific object entry", the uplink bandwidth occupancy rate corresponding to the event type can be determined to be 10% by looking up the table 1.

When the information representing the uplink bandwidth occupancy of the monitoring data includes the uplink bandwidth occupancy priority of the monitoring data, taking a home environment as an example, a preset mapping relationship between different event types and the information representing the uplink bandwidth occupancy of the monitoring data may be as shown in table 2. In table 2, the smaller the number indicating the priority of the occupied uplink bandwidth, the higher the priority of the uplink bandwidth.

Table 2:

event type	Priority of upstream bandwidth occupancy
		Intrusion detection	1
Carryover detection	3
		Motion detection	3
Object-specific entry	2
		Baby crying	1

By querying the table 1, the NVR can determine the uplink bandwidth occupation priority matched with each event type according to the respective corresponding event type of each monitoring data to be transmitted by using the uplink bandwidth. For example, if the event type corresponding to the monitoring data to be transmitted by using the uplink bandwidth from the front-end monitoring device 1 is "intrusion detection", the priority level of the uplink bandwidth occupation corresponding to the event type may be determined to be 1 by looking up the table 1; if the event type corresponding to the monitoring data to be transmitted by using the uplink bandwidth from the front-end monitoring device 1 is "specific object entry", the priority level of the uplink bandwidth occupation corresponding to the event type can be determined to be 2 by looking up the table 1.

It should be noted that the priority of the occupancy of the uplink bandwidth of the monitoring data may characterize the occupancy of the uplink bandwidth of the monitoring data to a certain extent. Generally speaking, the higher the priority occupied by the uplink bandwidth is, the higher the corresponding uplink bandwidth occupancy rate is; conversely, the lower the priority level occupied by the uplink bandwidth is, the lower the corresponding occupancy rate of the uplink bandwidth is. Subsequently, for a device (such as a router or other devices with a routing function) responsible for performing uplink bandwidth allocation, after obtaining the uplink bandwidth occupation priority of each monitoring data, a preset uplink bandwidth allocation policy based on the uplink bandwidth occupation priority may be further combined to determine how much uplink bandwidth should be specifically allocated to each monitoring data.

For example, for the monitoring data with the highest priority (e.g., "1") of uplink bandwidth occupancy, if the preset policy includes "for the highest priority of uplink bandwidth, the corresponding bandwidth occupancy satisfies: and taking high-definition smooth transmission as a reference, wherein the highest occupied rate is 100% ", if the monitoring data to be transmitted by using the uplink bandwidth currently only has the monitoring data with the highest priority of the uplink bandwidth, all the uplink bandwidth can be allocated to the monitoring data for use. In practical application, the specific content of the policy can be flexibly set according to actual requirements, and is not listed one by one here.

When the information representing the uplink bandwidth occupancy of the monitoring data includes the uplink bandwidth occupancy priority of the monitoring data and the uplink bandwidth allocation policy based on the uplink bandwidth occupancy priority, taking a home environment as an example, a preset mapping relationship between different event types and the information representing the uplink bandwidth occupancy of the monitoring data may be as shown in table 3. In table 3, the smaller the number indicating the priority of upstream bandwidth occupation,

indicating that the higher the priority of the upstream bandwidth.

Table 3:

for table 3, the meaning of the uplink bandwidth allocation policy "can occupy 100% at most based on high-definition smooth transmission" included therein means that: if the front-end monitoring device includes a camera and the corresponding monitoring data to be sent by using the uplink bandwidth is a high-definition video stream, if the uplink bandwidth occupation priority corresponding to the event type included in the high-definition video stream is "1", the uplink bandwidth allocated to the high-definition video stream should satisfy: and when the high-definition video stream is transmitted by utilizing the uplink bandwidth, the code rate of the high-definition video stream is not reduced. Furthermore, the meaning also includes: if the total upstream bandwidth is large, the upstream bandwidth allocated to the high definition video stream may only occupy a portion, such as 50%, of the total upstream bandwidth; if the total upstream bandwidth is smaller, the upstream bandwidth allocated to the high definition video stream may account for a larger percentage, such as 100%, of the total upstream bandwidth.

In addition, the uplink bandwidth allocation policy corresponding to the uplink bandwidth occupation priority 1 further includes "if there are other monitoring data with the uplink bandwidth occupation priority 1, the uplink bandwidth is equally divided with the other monitoring data". The meaning of the policy is that when different monitoring data with the priority 1 occupied by the uplink bandwidth exist in the monitoring data to be transmitted by using the uplink bandwidth, the uplink bandwidth is allocated to each monitoring data with the priority 1 occupied by the uplink bandwidth in a manner of equally dividing the total uplink bandwidth.

Some other upstream bandwidth allocation policies contained in table 3 are explained below.

The uplink bandwidth allocation policy corresponding to the uplink bandwidth occupation priority "2" in table 3 is "the remaining bandwidth after occupying priority 1 event; if the monitoring data with the same priority exist, the residual bandwidth is equally divided by the monitoring data with the same priority, and the meaning of the strategy is as follows: if the monitoring data transmitted by the current uplink bandwidth to be utilized not only contains monitoring data with an uplink bandwidth occupation priority of 2, but also contains monitoring data with an uplink bandwidth occupation priority of 1, then preferentially distributing the uplink bandwidth for the monitoring data with the uplink bandwidth occupation priority of 1 according to an uplink bandwidth distribution strategy corresponding to the uplink bandwidth occupation priority of 1; and then, if the remaining uplink bandwidth exists, allocating the remaining uplink bandwidth to the monitoring data with the uplink bandwidth occupation priority of 2. And if different monitoring data with the uplink bandwidth occupation priority 2 exist in the monitoring data to be transmitted by utilizing the uplink bandwidth, allocating the uplink bandwidth to each monitoring data with the uplink bandwidth occupation priority 2 according to a mode of equally dividing the residual uplink bandwidth.

The uplink bandwidth allocation policy corresponding to the uplink bandwidth occupation priority "3" in table 3 is "the remaining bandwidth after occupying priority 1, 2 events; if the monitoring data with the same priority exist, the residual bandwidth is equally divided by the monitoring data with the same priority, and the meaning of the strategy is as follows: if the monitoring data transmitted by the current uplink bandwidth to be utilized not only contains monitoring data with an uplink bandwidth occupation priority of 3, but also contains monitoring data with an uplink bandwidth occupation priority of 1 and/or monitoring data with an uplink bandwidth occupation priority of 2, preferentially distributing the uplink bandwidth for the monitoring data with the uplink bandwidth occupation priority of 1 according to an uplink bandwidth distribution strategy corresponding to the uplink bandwidth occupation priority of '1'; allocating uplink bandwidth for the monitoring data with the uplink bandwidth occupation priority of 2 according to an uplink bandwidth allocation strategy corresponding to the uplink bandwidth occupation priority of 2; and then, if the remaining uplink bandwidth exists, allocating the remaining uplink bandwidth to the monitoring data with the uplink bandwidth occupation priority of 3. And if different monitoring data with the uplink bandwidth occupation priority 3 exist in the monitoring data to be transmitted by utilizing the uplink bandwidth, allocating the uplink bandwidth to each monitoring data with the uplink bandwidth occupation priority 3 according to a mode of equally dividing the residual uplink bandwidth.

In the embodiment of the present application, some pieces of information characterizing the estimated uplink bandwidth occupancy of each monitoring data are listed exemplarily, and in practical application, other information may also be used to characterize the estimated uplink bandwidth occupancy of each monitoring data according to actual situations and requirements, which is not illustrated here. However, any content that is substantially used for characterizing the respective estimated upstream bandwidth occupancy of each monitoring data belongs to the category of the information for characterizing the respective estimated upstream bandwidth occupancy of each monitoring data described in the embodiments of the present application.

And step 23, the NVR allocates the uplink bandwidth for transmitting each monitoring data according to the information representing the predicted uplink bandwidth occupancy rate of each monitoring data.

In this embodiment of the application, according to the information representing the estimated occupancy rate of the uplink bandwidth of each monitoring data, the NVR may allocate the uplink bandwidth for transmitting each monitoring data in two specific implementation manners: an indirect allocation scheme, and a direct allocation scheme.

Still taking the scenario shown in fig. 2a as an example, the indirect allocation manner is that the NVR sends the determined information representing the estimated occupancy rate of the uplink bandwidth of each monitoring data to the router, so that the router allocates the uplink bandwidth for transmitting each monitoring data according to the information.

In the scenario shown in fig. 2a, for the same monitoring data, the front-end monitoring device may send the same monitoring data to both the NVR local and the router, so that the router uses the uplink bandwidth for sending. Therefore, the event type corresponding to the monitoring data determined by the NVR is the same as the event type corresponding to the monitoring data to be sent by using the upstream bandwidth at the router. In such a scenario, for a specific implementation process of the indirect allocation manner, for example, the NVR may send the information, the identifier of the front-end monitoring device corresponding to each monitoring data, and a mapping relationship between the information and the identifier of the front-end monitoring device corresponding to each monitoring data to the router.

After the router receives the contents, on one hand, the router can determine the uplink bandwidth which is respectively expected to be occupied by each monitoring data according to the information; on the other hand, according to the identifier of the front-end monitoring device corresponding to each monitoring data and the mapping relationship between the information and the identifier of the front-end monitoring device corresponding to each monitoring data, it may be determined to which front-end monitoring device the uplink bandwidth expected to be occupied by each monitoring data should be allocated to transmit the monitoring data, and further, the determined uplink bandwidth expected to be occupied by each monitoring data is correspondingly allocated to each monitoring data transmitted to the router by the front-end monitoring device having the identifier.

For example, if it is assumed that the determined information characterizing the estimated occupancy rate of the uplink bandwidth of each monitoring data includes:

the priority of upstream bandwidth occupation of the monitoring data 1 (high definition video stream, bit rate 4933kbps) is 1, and an upstream bandwidth allocation strategy corresponding to the priority 1 of upstream bandwidth occupation is shown in table 3;

the uplink bandwidth occupation priority of the monitoring data 2 (high definition video stream, bit rate 4933kbps) is 2, and the uplink bandwidth allocation strategy corresponding to the uplink bandwidth occupation priority 2 is shown in table 3;

the priority of uplink bandwidth occupation of the monitoring data 3 (standard definition video stream, bitrate 1024kbps) is 3, and the uplink bandwidth allocation policy corresponding to the priority of uplink bandwidth occupation of 3 is shown in table 3.

Further, assume that monitoring data 1, monitoring data 2, and monitoring data 3 are from front-end monitoring device a, front-end monitoring device B, and front-end monitoring device C, whose IP addresses are 192.168.1.2, 192.168.1.3, 192.168.1.4, respectively.

Then, the NVR may send the information representing the estimated occupancy rates of the uplink bandwidths of the monitoring data 1, the monitoring data 2, and the monitoring data 3, respectively, and the IP addresses to the router, where the information is carried in an instruction. For ease of description, the instruction may be referred to as a bandwidth control instruction. The instruction includes the contents, and also includes the information representing the estimated upstream bandwidth occupancy rates of the monitoring data 1, the monitoring data 2, and the monitoring data 3, and the mapping relationship of the IP addresses. Of course, if only the monitoring data 1 to be transmitted by using the uplink bandwidth exists currently, the mapping relationship may not be required to be transmitted.

In the embodiment of the present application, the bandwidth control instruction may be generated according to a private protocol agreed in advance between the router and the NVR. In the private protocol, a format of the bandwidth control instruction may be specified, and after the bandwidth control instruction generated by the NVR according to the format is sent to the router, the router may analyze the bandwidth control instruction according to the protocol, so as to obtain various information included in the bandwidth control instruction.

After receiving the bandwidth control instruction, the router can determine that the monitoring data to be currently subjected to uplink bandwidth allocation are respectively from the monitoring data of the IP addresses according to the IP addresses 192.168.1.2, 192.168.1.3 and 192.168.1.4; then, the router may determine the code rates of the monitoring data from the IP addresses respectively — that is, determine the respective code rates of monitoring data 1, monitoring data 2, and monitoring data 3 (the code rates may be obtained by analyzing the code rates of the monitoring data from the IP addresses in real time); in addition, if it is assumed that the current uplink total bandwidth is 10Mbps, the router may determine, according to the uplink bandwidth allocation policies corresponding to the uplink bandwidth occupation priorities 1, 2, and 3, and the respective code rates of the monitoring data 1, the monitoring data 2, and the monitoring data 3: upstream bandwidth 4933kbps can be allocated for monitoring data 1, and upstream bandwidth 4933kbps can be allocated for monitoring data 2; the remaining bandwidth can then be allocated to the monitoring data 3.

The router can realize the distribution of the uplink bandwidth for the monitoring data by automatically changing the maximum bandwidth corresponding to the IP address of the front-end monitoring equipment in the mode of limiting the maximum bandwidth. For example, the router may change the maximum bandwidth corresponding to the IP address 192.168.1.2 of the front-end monitoring device a to 5Mbps according to the bandwidth control instruction in the "limit maximum bandwidth" mode, so as to meet the requirement of allocating at least upstream bandwidth 4933kbps (about 5Mbps) to the monitoring data 1.

It should be noted that, after receiving the monitoring data 1, the monitoring data 2, and the monitoring data 3 respectively transmitted from the front-end monitoring device a, the front-end monitoring device B, and the front-end monitoring device C, respectively, and before transmitting the monitoring data by using the uplink bandwidth, the router may first store the monitoring data in a cache of the router, and meanwhile, wait for a bandwidth control instruction sent by the NVR. Subsequently, after receiving the bandwidth control instruction, the router may read the monitoring data from the cache and send the monitoring data using the allocated corresponding uplink bandwidth. When the router stores the monitoring data in the cache, the router can adopt a mode of storing the monitoring data from different IP addresses in different partitions of the cache, so that the monitoring data from different IP addresses can be distinguished during reading.

The above is a specific example of the indirect allocation approach employed.

For the direct allocation mode, the realization premise is that the NVR integrates the routing function. If the NVR integrates the function, the NVR may determine the size of the uplink bandwidth allocated to each monitoring data directly according to the information of the estimated occupancy rate of the uplink bandwidth of each monitoring data and the total uplink bandwidth; and then, respectively allocating uplink bandwidths to the monitoring data according to the determination result. In this case, NVR is equivalent to a function of implementing one router. The specific implementation manner of this manner is similar to the implementation manner in which the router allocates the uplink bandwidth to the monitoring data according to the content included in the bandwidth control instruction, and details are not described here.

Whether an indirect distribution mode or a direct distribution mode is adopted, corresponding uplink bandwidth can be distributed to each monitoring data according to the information representing the estimated occupancy rate of the uplink bandwidth of each monitoring data, so that part or even all of the monitoring data in each monitoring data can be distributed to the uplink bandwidth matched with the event type corresponding to the monitoring data, and the problem that the uplink bandwidth actually distributed to the monitoring data to be transmitted by utilizing the uplink bandwidth is not matched with the uplink bandwidth required by the monitoring data due to the adoption of the prior art is avoided to a certain extent. In addition, the method realizes the self-adaptive adjustment of the uplink bandwidth allocation mode according to the event type of the monitoring data, thereby providing a scheme for flexibly adjusting the uplink bandwidth occupied by the monitoring data from different front-end monitoring equipment based on the event type.

In addition, whether an indirect allocation manner or a direct allocation manner is adopted, after the uplink bandwidth for transmitting each monitoring data is successfully allocated by the NVR according to the information representing the predicted occupancy rate of the uplink bandwidth of each monitoring data, the transmission of the monitoring data can be performed according to the uplink bandwidth allocation result within a period of time. The period of time may be a preset length of time, such as 30 minutes. After the period of time is over, steps 21 to 23 may be executed again, so as to allocate the uplink bandwidth according to the event types corresponding to the monitoring data newly received by the NVR. Or, instead of waiting for the end of the period of time, once the NVR receives new monitoring data, steps 21 to 23 may be executed again to implement reallocation of the uplink bandwidth according to the event types respectively corresponding to the monitoring data newly received by the NVR.

In the above, from the perspective of using the backend device as an execution subject, a specific implementation procedure of the uplink bandwidth allocation method provided in the embodiment of the present application is introduced. In the following, from the perspective of a router, an uplink bandwidth allocation method provided in the embodiments of the present application is introduced, and the method is also used to solve the problem that an uplink bandwidth actually allocated to monitoring data to be transmitted using the uplink bandwidth does not match an uplink bandwidth required by the monitoring data.

Referring to fig. 3 in the description, an implementation flowchart of an uplink bandwidth allocation method provided in an embodiment of the present application is mainly shown, where the process mainly includes the following steps:

and step 31, the router receives information representing the predicted occupancy rate of the uplink bandwidth of each monitoring data to be sent by using the uplink bandwidth.

The information received by the router may be determined and sent by a back-end device (e.g., NVR, etc.).

And the information is determined according to the event types respectively corresponding to the monitoring data. For a specific determination method of the information and specific contents of the information, please refer to the specific description of the method shown in fig. 2b, which is not described herein again.

And step 32, the router allocates the uplink bandwidth for transmitting each monitoring data according to the received information representing the predicted occupancy rate of the uplink bandwidth of each monitoring data to be transmitted by using the uplink bandwidth. When there are multiple monitoring data (such as multiple video streams) to be sent by using the uplink bandwidth, the router may further receive the identifier of the front-end monitoring device corresponding to each monitoring data. In such a case, the specific implementation manner of step 32 may include:

the router determines the uplink bandwidth which is respectively expected to be occupied by each monitoring data according to the information;

and correspondingly allocating the uplink bandwidths which are respectively expected to be occupied to the front-end monitoring equipment with the identifier according to the identifier so that the front-end monitoring equipment with the identifier can utilize the allocated uplink bandwidths to send the monitoring data. Specifically, for example, if the router allocates an uplink bandwidth of 10Mbps to the front-end monitoring device identified as "a", the router may send the monitoring data from the front-end monitoring device by using the uplink bandwidth of 10Mbps if receiving the monitoring data from the front-end monitoring device. The identifier of the front-end monitoring device may also be an IP address of the front-end monitoring device.

And the router determines the specific implementation process of the uplink bandwidth which is respectively expected to be occupied by each monitoring data according to the information, wherein the contents of the information are different.

Specifically, when the information includes the estimated uplink bandwidth occupancy of each monitoring data, the router may determine, according to the estimated uplink bandwidth occupancy and the total uplink bandwidth of each monitoring data, the uplink bandwidth that each monitoring data is expected to occupy, respectively. For example, if the estimated occupancy rate of the uplink bandwidth of a certain monitoring data is 50%, and the total uplink bandwidth is 5Mbps, the estimated uplink bandwidth occupied by the monitoring data is 2.5 Mbps.

And when the information comprises the uplink bandwidth occupation priority of each monitoring data, determining the uplink bandwidth which is respectively expected to be occupied by each monitoring data according to the uplink bandwidth occupation priority of each monitoring data and a locally stored uplink bandwidth allocation strategy based on the uplink bandwidth occupation priority. The uplink bandwidth allocation policy based on the uplink bandwidth occupation priority may be as shown in table 3, and a mapping relationship between the policies and the uplink bandwidth occupation priority may be preset and stored locally in the router. For a specific implementation of this method, please refer to the related embodiments, and the description is not repeated here.

And when the information comprises the uplink bandwidth occupation priority of each monitoring data and an uplink bandwidth allocation strategy based on the uplink bandwidth occupation priority, determining the uplink bandwidth which is respectively expected to be occupied by each monitoring data according to the uplink bandwidth occupation priority of the monitoring data and the uplink bandwidth allocation strategy. For a specific implementation of this method, please refer to the related embodiments, and the description is not repeated here.

By adopting the method provided by the embodiment of the application, because the estimated occupancy rates of the uplink bandwidths of the monitoring data are matched with the event types respectively corresponding to the monitoring data, the uplink bandwidths finally allocated to the monitoring data can be matched with the event types respectively corresponding to the monitoring data, so that the problem that the uplink bandwidths actually allocated to the monitoring data to be transmitted by using the uplink bandwidths are not matched with the uplink bandwidths required by the monitoring data due to the adoption of the prior art is avoided.

Example 2

The inventive concept of the present application is described in detail based on the foregoing embodiment 1, and in order to better understand the technical features, means and effects of the present application, the following further describes the storage method of the monitoring data provided by the embodiment of the present application, thereby forming a further embodiment of the present application.

The implementation scenario of example 2 assumes: there is a home user and there are infants less than one year in the home, 3 cameras in the home, camera a, camera B and camera c, respectively, the 3 cameras and the NVR establish connections via the router, respectively. The network topology is shown in fig. 4 a.

In addition, the total uplink bandwidth of the home subscriber is assumed to be 10 Mbps. Further, the correlation of each camera is as follows:

a camera A: its camera is facing the doorway. The characteristics of the monitoring scene are as follows: more and more complicated personnel that pass by are mostly triggering and moving and detecting the warning. The principle of Motion detection, also called Motion detection, is that different image frames acquired by a camera are calculated and compared by a CPU according to a certain algorithm, and when a person walks through a monitoring scene to cause a change in the content of the image frames, the CPU obtains a corresponding calculation and comparison result indicating that the person moves in the monitoring scene, thereby determining that a "Motion detection" type event occurs. Motion detection is a well-established correlation technique and is not described herein.

The motion detection alarm means that if the image frames acquired by the camera in real time are analyzed to determine that a motion detection type event occurs, the image frames acquired by the camera in real time are stored by the camera, and meanwhile, the camera can send alarm information.

A camera B: its camera is opposite to the second floor balcony. The characteristics of the monitoring scene are as follows: the number of events that trigger an alarm is small, but once an alarm is triggered, it is typically an intrusion detection alarm. The intrusion detection refers to performing image processing, pattern recognition and the like on image frames acquired (acquired in a scanning manner) by a camera, judging whether behaviors of target objects in the image frames meet preset intrusion conditions, and if yes, judging that an event of an intrusion detection type occurs. Intrusion detection may generally include zone intrusion detection and tripwire intrusion detection. Since image frame based intrusion detection is a mature prior art, it is not described here in detail.

The intrusion detection alarm means that if the image frames acquired by the camera in real time are analyzed to determine that an event of an intrusion detection type occurs, the image frames acquired by the camera in real time are stored by the camera, and meanwhile, the camera can send alarm information.

A camera C: its camera is facing the baby room. The characteristics of the monitoring scene are as follows: the owner does not need to give an alarm when in the room, but needs to start monitoring when not in the room, the number of events for triggering the alarm is small, and once the alarm is triggered, the alarm is generally a crying alarm for the baby. The term "baby cry" refers to a determination as to whether or not the vocal print characteristics of the audio data included in the monitored data are identical to the vocal print characteristics of the audio data extracted in advance from the baby cry, and if the vocal print characteristics are identical, it can be determined that the type of the event appearing in the monitored data is "baby cry".

The infant crying alarm means that if the type of an event appearing in the monitoring data is judged to be 'infant crying', the camera stores image frames acquired in real time, and meanwhile, the camera can send alarm information.

The different types of events are classified mainly according to the detection mode. Depending on the nature of the home environment, the types of events that may occur may include "intrusion detection", "motion detection", and "baby crying", as well as "carry-over detection" and "specific object entry".

In the embodiment of the present application, a mapping relationship between different event types, bandwidth occupation priorities, and an uplink bandwidth allocation policy based on the uplink bandwidth occupation priorities may be preset, as shown in table 3.

Based on the above assumptions, the following illustrates an uplink bandwidth allocation procedure.

Please refer to fig. 4b in the description, which is a flowchart illustrating an implementation of the uplink bandwidth allocation procedure in embodiment 2 of the present application. The process mainly comprises the following steps:

step 41, the NVR analyzes the video streams sent by the camera a, the camera B and the camera C respectively in real time to determine the event types corresponding to the video streams respectively.

For example, assume that the event types corresponding to the video streams transmitted by camera a, camera B, and camera C are "motion detection", "intrusion detection", and "baby cry", respectively.

Step 42, determining, by the NVR, bandwidth occupation priorities mapped by event types corresponding to video streams respectively transmitted by the camera a, the camera B, and the camera C and an uplink bandwidth allocation policy based on the uplink bandwidth occupation priorities through the lookup table 3;

as can be seen from table 3, by looking up table 3, NVR can obtain that the bandwidth occupation priorities mapped respectively with "mobile detection", "intrusion detection" and "baby cry" are "3", "1" and "1", and 3 uplink bandwidth allocation policies based on the uplink bandwidth occupation priorities mapped sequentially are as follows:

occupying the residual bandwidth after the events of the priority 1 and the priority 2; if the monitoring data with the same priority exist, the residual bandwidth is equally divided with the monitoring data with the same priority;

the highest occupied rate can be 100 percent by taking high-definition smooth transmission as a reference; if other monitoring data with the uplink bandwidth occupation priority of 1 exist, the uplink bandwidth is equally divided with other monitoring data;

the highest occupied rate can be 100 percent by taking high-definition smooth transmission as a reference; if other monitoring data with the uplink bandwidth occupation priority of 1 exist, the uplink bandwidth is equally divided with other monitoring data.

And step 43, the NVR issues a bandwidth control instruction to the router according to the query result of the table 3. The bandwidth control command includes ID numbers of a camera a, a camera B, and a camera C that respectively send video streams, and 3 uplink bandwidth allocation policies based on the bandwidth occupation priorities mapped by the queried event types corresponding to the video streams and the uplink bandwidth occupation priorities.

And step 34, the router allocates uplink bandwidth for the video streams respectively sent by the camera A, the camera B and the camera C according to the bandwidth control instruction.

Assuming that the code rates of the video streams sent by the camera a, the camera B, and the camera C are all 4Mbps, according to the uplink total bandwidth of 10Mbps, the priorities "3", "1", and "1" occupied by the bandwidths corresponding to the video streams sent by the camera a, the camera B, and the camera C, and the corresponding uplink bandwidth allocation policy, the uplink bandwidths of 2Mbps, 4Mbps, and 4Mbps may be allocated to the video streams sent by the camera a, the camera B, and the camera C to the router, respectively.

Through the above process, the uplink bandwidth finally allocated to each video stream can be matched with the event type respectively corresponding to each video stream, so that the problem that the uplink bandwidth actually allocated to the video stream to be transmitted by using the uplink bandwidth is not matched with the uplink bandwidth required by the video stream due to the adoption of the prior art is avoided.
