All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
The application mainly solves the problems that the equipment flow package is fixed, and the video cannot be transmitted due to arrearage shutdown after the flow is over-expected or a large amount of SIM (subscriber identity Module) fees are additionally spent on exceeding the user flow package caused by the equipment emergency, and particularly provides a system and a method for realizing the high-reliability transmission of the video based on a flow balancing strategy.

The video transmission method is applied to a video transmission device, wherein the video transmission device can be a server or a system formed by the cooperation of the server and the terminal equipment. Accordingly, each part, such as each unit, sub-unit, module, and sub-module, included in the video transmission apparatus may be all disposed in the server, or may be disposed in the server and the terminal device, respectively.
Further, the server may be hardware or software. When the server is hardware, the server may be implemented as a distributed server cluster formed by a plurality of servers, or may be implemented as a single server. When the server is software, it may be implemented as a plurality of software or software modules, for example, software or software modules for providing a distributed server, or may be implemented as a single software or software module, which is not specifically limited herein. In some possible implementations, the model training method for video transmission of the embodiments of the present application may be implemented by a processor invoking computer readable instructions stored in a memory.
In the embodiment of the present application, the video transmission device may specifically be a monitoring platform or a cloud platform shown in fig. 1.
As shown in fig. 1, the video transmission system provided by the present application mainly relates to a low-power-consumption device cluster, and in this embodiment, a device a, a device B, a device C, and a device D are used as examples. And after the low-power consumption equipment is powered on, the low-power consumption equipment is sequentially registered to the cloud platform through the cellular network 4G or 5G module. Meanwhile, each monitor user device starts a WIFi hot spot mode and scans surrounding hot spots, and the monitor user device is used for finding surrounding neighbor monitor device information. When the platform is accessed for the first time, the flow package information and the neighbor monitoring equipment information of the current monitoring equipment need to be reported. Meanwhile, when the monitoring equipment is deployed and installed, the SIM card operators need to be deployed in a crossing way, the equipment in the same deployment area needs to be installed with cards of different operators, and as shown in the system example diagram, equipment A, equipment B, equipment C and equipment D are arranged in the area, wherein the equipment A can be provided with a mobile SIM card, the equipment B is provided with a communication SIM card, the equipment C is provided with a telecommunication SIM card, and the equipment D is provided with a telecommunication SIM card, so that at least 1 standby cellular channels exist at any moment.
Specifically, as shown in fig. 2, the video transmission method in the embodiment of the application specifically includes the following steps:
step S11: and responding to the video transmission instruction, and acquiring the available traffic of the target monitoring equipment on the first day.
In the embodiment of the present application, as shown in fig. 3, the main sources of the video transmission instruction received by the monitoring platform mainly include a user side and a monitoring device side, and specifically, the video transmission instruction may be triggered by the target monitoring device to wake up locally, or may be generated by the user side based on a pull stream instruction of the user for the target monitoring device.
Specifically, assuming that a PIR (Passive Infrared Secsor, human infrared sensor) sensor of the monitoring device D senses that a person passes by at a certain moment, local wake-up is triggered, and the device starts to push the collected code stream information to the cloud platform in real time. If the equipment monitors that the picture changes all the time, the code stream is continuously transmitted to the cloud platform, and the equipment can update the current residual flow information periodically in the code stream transmission process.
In another embodiment, it is assumed that at a certain moment, the user wakes up the device C remotely through the mobile phone APP to perform streaming, and a video transmission instruction may also be generated at the cloud platform end.
It should be noted that the residual flow rate and the available flow rate mentioned in the present application are recorded in days. Assuming that the SIM card month package installed by the monitoring device is 31GB, 1GB can be used on average every day, and the remaining flow on the nth day (1 < =n < =31) of the device is as follows: available 1GB for the day + available traffic remaining on day N-1. If the number of code streams to be uploaded on the same day is large, the available residual traffic on the same day gradually becomes 0 along with the increase of the pull time.
Specifically, the cloud platform determines a first current available flow of a target monitoring device needing to perform video data streaming in the low-power consumption monitoring device cluster according to a video transmission instruction.
Step S12: and when the available traffic on the first day is smaller than or equal to a preset traffic threshold, acquiring a second current available traffic of the neighbor monitoring equipment of the target monitoring equipment.
In the embodiment of the application, when the first current available flow of the target monitoring device is smaller than or equal to a preset flow threshold, for example, the first current available flow is smaller than or equal to 0, the cloud platform starts comprehensive scheduling to confirm whether other transmission channels exist in the current device for code stream transmission. At this time, the cloud platform may obtain the second current available traffic of the neighbor monitoring device of the target monitoring device.
When the first current available flow of the target monitoring device is larger than a preset flow threshold, for example, the first current available flow is larger than 0, the cloud platform directly wakes up the target monitoring device, and video transmission is carried out by the target monitoring device through a cellular network of the cloud platform.
Step S13: and determining the optimal neighbor monitoring equipment of the target monitoring equipment according to the second current available flow of the neighbor monitoring equipment.
In the embodiment of the application, when the second current available flow of all the neighbor monitoring devices of the target monitoring device is smaller than or equal to the preset flow threshold, that is, the target monitoring device is confirmed to have no other transmission channels, at this time, the target monitoring device needs to overdraft the future flow of the device, that is, the continuous code stream transmission of the n+1th day or even the n+2th day, at this time, the available residual flow of the device is marked as a negative value, and how much of the overdraft the future day is negative. Further, if the remaining traffic is negative and the code stream still needs to be transmitted continuously, the device reduces the code stream parameters and reduces the amount of transmitted data.
When the second current available flow of at least one neighbor monitoring device in all neighbor monitoring devices of the target monitoring device is larger than a preset flow threshold, the target monitoring device is confirmed to have other transmission channels, at this time, the target monitoring device directly takes the neighbor monitoring device with the second current available flow being the largest as the optimal neighbor monitoring device, and video data of the target monitoring device is uploaded by means of the transmission channel of the optimal neighbor monitoring device.
In a specific embodiment, the cloud platform may also select the optimal neighbor monitoring device from all the neighbor monitoring devices using the platform optimal channel selection logic as described in fig. 4.
Specifically, as shown in fig. 4, when the current remaining available flow M of the target monitoring device is less than or equal to 0, the cloud platform obtains current state information of all neighbor monitoring devices of the target monitoring device, including whether the current remaining flow is in a pull flow mode, and the like. And the cloud platform judges whether available residual flow exists in the neighbor monitoring equipment, if not, the code flow parameters are reduced, and the flow of future days is pre-branched for flow pulling. If the available residual flow exists in the neighbor monitoring device, preferentially judging whether the neighbor monitoring device in the pull-flow mode exists or not, wherein the current available residual flow is enough to pull the target monitoring device. If the neighbor monitoring device exists, the neighbor monitoring device can be regarded as the optimal neighbor monitoring device; if not, continuing to judge whether the neighbor monitoring equipment in the sleep mode exists, and the current available residual flow is enough to pull the current flow to the target monitoring equipment. If the neighbor monitoring device exists, the neighbor monitoring device can be regarded as the optimal neighbor monitoring device.
In other embodiments, when determining that there is a residual flow available to the neighbor monitoring device, the cloud platform may preferentially select, as the optimal neighbor monitoring device, a neighbor monitoring device different from the operator type of the target monitoring device from among the neighbor monitoring devices having a residual flow available at present enough to pull the target monitoring device. For example, when the operator type of the target monitoring device is mobile, the operator type of the optimal neighbor monitoring device may be either a telecommunications or a telecommunications. By means of differentiated deployment of the SIM card operator types of the monitoring equipment and platform optimal channel selection logic, the transmission channels of each operator type can be guaranteed to realize flow sharing, and the utilization rate of each transmission channel is improved.
Step S14: and sending the video transmission instruction to the target monitoring equipment and the optimal neighbor monitoring equipment so that the target monitoring equipment transmits the video data to the optimal neighbor monitoring equipment, and uploading the video data to the monitoring platform by the optimal neighbor monitoring equipment.
In the embodiment of the present application, as shown in fig. 3, after determining the optimal neighbor monitoring device of the target monitoring device through the above steps, the cloud platform may wake up the optimal neighbor monitoring device, and upload the video data of the target monitoring device by using the transmission channel provided by the optimal neighbor monitoring device.
Specifically, the cloud platform notifies neighbor devices selected as optimal nodes to open wifi hotspots, wherein hotspot parameters include, but are not limited to: the wifi ssid (Service Set Identifier) and the authentication parameters are specified by a platform, and meanwhile, the hot spot parameters are notified to the target monitoring equipment to perform wifi connection. And when the wifi connection of the target monitoring equipment is OK, switching the code stream from the cellular network transmission to the wifi network transmission of the neighbor monitoring equipment, and then forwarding the video code stream received by the optimal neighbor monitoring equipment to the cloud platform through the cellular network of the optimal neighbor monitoring equipment. And the cloud platform is informed to enter a sleep mode after the target monitoring equipment finishes the streaming, and at the moment, the optimal neighbor monitoring equipment closes the hot spot network and also enters the sleep mode.
In other embodiments, the hotspot parameters of the optimal neighbor monitoring device may also be determined by the device itself, and uploaded to the cloud platform by the optimal neighbor monitoring device, or directly sent to the target monitoring device.
In the embodiment of the application, a monitoring platform, namely a cloud platform, responds to a video transmission instruction to acquire the available flow of the target monitoring equipment on the first day; when the available flow on the first day is smaller than or equal to a preset flow threshold, acquiring a second current available flow of the neighbor monitoring equipment of the target monitoring equipment; determining an optimal neighbor monitoring device of the target monitoring device according to the second current available flow of the neighbor monitoring device; and sending the video transmission instruction to the target monitoring equipment and the optimal neighbor monitoring equipment so that the target monitoring equipment transmits video data to the optimal neighbor monitoring equipment, and uploading the video data to the monitoring platform by the optimal neighbor monitoring equipment. By the method, the video transmission device realizes high-reliability transmission of video data through the flow balance strategy, and flow sharing of the monitoring equipment cluster is realized.
The application designs a system and a method for realizing high-reliability video transmission based on a flow balancing strategy, which realize flow sharing of equipment clusters in a WiFI coverage area through differentiated deployment of equipment SIM card operator types, flow distribution strategy taking days as a unit, real-time reporting of uplink bandwidth information which can be borne by a cellular network and comprehensive scheduling of a cloud platform.
The cloud platform reduces the wake-up times as much as possible through the current residual flow, the uplink bandwidth and the energy-saving angle which can be borne by the current cellular network, and selects the optimal network channel to schedule the equipment for video transmission.
