For example, in a multi-story building (as shown in fig. 9), if an Access Point (AP) is placed on the first floor, a signal on the second floor will be weak, and the third floor may not receive the signal, so that the wifi terminal device cannot be connected to the AP.
In order to solve the problem, a cascading manner (as shown in fig. 2) is often used to improve the effective coverage of wifi, in fig. 2, a first wifi device (or referred to as wifi relay device) simultaneously starts a Station (Station, abbreviated as STA) unit and an AP unit; the second wifi device is connected to the AP unit of the first wifi device through a wifi link; the first wifi device forwards the data of the second wifi device received by the AP unit to the STA unit of the first wifi device through the forwarding unit; the STA unit of the first wifi device sends data to a wifi router through a first wifi link; after the first wifi device receives the data of the wifi router, whether the destination of the first wifi device is the second wifi device or the self destination of the first wifi device is judged, if the destination of the first wifi device is the second wifi device, the first wifi device forwards the data to the AP unit through the forwarding unit, and the AP unit forwards the data to the second wifi device.
Wherein: a plurality of other wifi devices can be connected to the AP unit of the first wifi device through the STA unit of the other wifi devices; the forwarding unit has multiple implementation modes, and can forward in a data link layer of Open system interconnection (OSI for short), or forward in a higher layer; after the first wifi device receives data sent by the wifi router, there are also many methods for determining the destination device, and based on different implementation manners of the forwarding units, the determination may be performed through a destination MAC Address (Media Access Control Address, abbreviated as MAC), or may be performed through a higher layer by adding a feature tag.

For better understanding of a data transmission processing flow defined in the embodiment of the present invention, as shown in fig. 4:
in the related art, there is also a cascade scheme in which:
1) the NVR supports the AP function of wifi;
2) the IPC supports the functions of STA and soft AP (the function of the AP is similar to that of the AP by realizing the simulation of the AP through software) of wifi;
3) IPCs connected by other IPCs, such as the first IPC and the third IPC, are called relay IPCs;
4) IPCs that are not connected by other IPCs, such as second, fourth, fifth, and sixth IPCs, are called edge IPCs;
5) all IPCs have the capability of simultaneously starting STA and soft AP, and are called relay IPCs or edge IPCs completely determined by the network connection relationship.
However, in the existing scheme, the IPC may transmit the video data to the NVR in real time, and the data volume is relatively large, so that a situation that the forwarding capability of the relay device (such as the first wifi device and the third wifi device in fig. 4) is insufficient may often occur, at this time, the relay device may release wifi connection of the lower wifi devices (such as the second wifi device, the fourth wifi device, and the fifth wifi device in fig. 4) connected to the relay device according to the order of access, for example, the fourth IPC is connected to the third IPC first, at this time, the third IPC needs to send its video data and the video data of the fourth IPC to the NVR, and the capability is sufficient; then, the fifth IPC is also connected to the third IPC, at this time, the third IPC needs to send its video data, the video data of the fourth IPC, and the video data of the fifth IPC to the NVR, and at this time, the wifi forwarding capability of the third IPC is insufficient; because the fifth IPC is post-connected, the third IPC disconnects wifi connection with the fifth IPC; if the third IPC forwarding capability is still insufficient due to wifi signal fluctuation, the wifi connection with the fourth IPC is disconnected again.
It should be noted that the IPC mainly functions to capture video, and the video has different importance levels according to different contents, in the above-mentioned cascading scheme, for example, the fourth IPC captures video of a utility room, the fifth IPC captures video of a baby room, and the importance level of the baby room is set to be higher than that of the utility room.
In order to solve the possible problems in the above technical solutions, in this embodiment, a data transmission processing method is provided, and fig. 5 is a flowchart of the data transmission processing method according to the embodiment of the present invention, as shown in fig. 5, including the following steps:
step S502, when a target relay IPC device in a cascade system detects that data transmission congestion occurs in the cascade system, a priority set is obtained, wherein the priority set comprises: the priority information of the target relay IPC equipment and the priority information of the lower IPC equipment of the target relay equipment;
step S504, determine the first IPC device corresponding to the lowest priority in the priority set, and interrupt the data transmission of the first IPC device, wherein the first IPC device at least includes one of the following: the target relay IPC device and the lower IPC device.
Through the technical scheme, under the condition that the target relay IPC equipment in the cascade system detects that data transmission congestion occurs in the cascade system, a priority set is obtained, wherein the priority set comprises the following steps: the priority information of the target relay IPC equipment and the priority information of the lower IPC equipment of the target relay equipment; determining a first IPC device corresponding to the lowest priority in the priority set, and interrupting data transmission of the first IPC device, wherein the first IPC device at least comprises one of the following components: the target relay IPC device and the lower IPC device. By adopting the technical scheme, the problems that in the related art, when the network is congested (for example, the relay IPC forwarding capability is insufficient), the high-priority data to be transmitted is easy to lose and the like are solved, and then the data transmission of the first IPC equipment can be interrupted according to the priority information, so that the data to be transmitted is effectively prevented from losing.
In an optional embodiment, determining a first IPC device corresponding to the lowest priority in the set of priorities and interrupting data transmission of the first IPC device includes: under the condition that the first IPC device corresponding to the lowest priority in the priority set is determined to be the target relay IPC device, interrupting data transmission of the target relay IPC device; and under the condition that the first IPC equipment corresponding to the lowest priority in the priority set is determined to be lower-level IPC equipment, acquiring the identification information of the lower-level IPC equipment, and disconnecting the data transmission of the lower-level IPC equipment corresponding to the identification information. When detecting that data transmission congestion occurs in a target relay IPC device in a cascade system, acquiring a priority set in an IPC device set, distinguishing priorities, interrupting the transmission of a database by the IPC device with the lowest priority of lower IPC devices transmitting data through the target relay IPC device, and acquiring identification information of the interrupted IPC device.
Through the embodiment, when the target relay IPC equipment in the cascade system has data transmission congestion, the IPC equipment with the lowest priority can be sequentially disconnected according to the priorities of the lower IPC equipment of the target relay IPC equipment to reduce the data congestion condition of the target relay IPC equipment, ensure the normal transmission of the data with high priority and reduce the data loss.
In an optional embodiment, in a case that it is determined that the first IPC device corresponding to the lowest priority in the priority set is a subordinate IPC device, the method further includes, after obtaining identification information of the subordinate IPC device and disconnecting data transmission of the subordinate IPC device corresponding to the flag information: identifying whether other relay IPC equipment exists in the cascade system; if the connection does not exist, after a preset time period, the connection is established again with the target relay IPC equipment through the lower IPC equipment; if the connection exists, the lower IPC equipment establishes connection with other relay IPC equipment. In the cascade system, there may be one lower IPC device performing data transmission through multiple relays IPC, so after disconnecting the lower IPC device with the lowest priority of the target relay IPC, after obtaining the identifier of the lower IPC device, it is to identify whether the disconnected lower IPC device is still connected to other relay IPC devices, when it is determined that the lower IPC device is only connected to the target relay IPC device, after passing a predetermined time period (for example, the predetermined time period may be one minute, one hour, which is not limited by the present invention), the disconnected lower IPC device re-establishes connection with the target relay IPC device, if there are other target relay IPC devices, the current disconnection state between the target relay IPC device and the lower IPC device is maintained, and the lower IPC device performs data transmission through the connections established by other relay IPC devices.
By the embodiment, when the data transmission congestion of the target relay IPC equipment in the cascade system is relieved, the connection with the target relay IPC equipment is recovered under the condition that the connection with other relay IPC equipment is not established, so that the data of the lower IPC equipment can be normally transmitted, and if the lower IPC equipment has a connection relation with other relay IPCs, the connection with other relay IPC equipment is maintained, and the connection established by the target relay IPC equipment of the lower IPC equipment is disconnected.
In an optional embodiment, before obtaining the set of priorities, the method further comprises: receiving indication information of a target object, wherein the indication information is determined according to at least one of the following information: data content and time information transmitted by the IPC equipment; in response to the indication information, priority information of the target relay IPC device and priority information of IPC devices subordinate to the target relay device are set. When the priority set is obtained, the data content and the time information of the data transmission of the IPC equipment need to be known, how the priority information in the target relay IPC equipment is set, and the priority information of the lower IPC equipment connected with the target relay IPC equipment.
Through the embodiment, the priority information of the target relay IPC device and the lower IPC device can be clearly set according to the indication information of the target object, and support is provided for acquiring the priority set information, for example, the time information can be a time node of information needing to be transmitted currently, or a time node of transmission content, and the data content is data to be transmitted of the lower IPC or data to be transmitted of the current IPC, which is not limited by the invention.
In an optional embodiment, determining a first IPC device corresponding to the lowest priority in the set of priorities and interrupting data transmission of the first IPC device includes: under the condition that a plurality of first IPC devices are arranged, the time of the plurality of first IPC devices accessing the cascade system is obtained; the first IPC device which is finally accessed to the cascade system is disconnected. For example, the target relay IPC device finds a plurality of lower IPC devices having the lowest priority when disconnecting the lower IPC having the lowest priority, and can preferentially disconnect the last connected lower IPC device by the time when the lower IPC is connected to the cascade system.
Through the embodiment, the first IPC device which is accessed into the cascade system at last is disconnected in the first IPC devices with the lowest priority, so that the IPC devices which enter the cascade system at first can transmit data back to the NVR to reduce data loss when a wifi network is congested.
The following explains the flow of the processing method for data transmission with an example, but is not intended to limit the technical solution of the embodiment of the present invention.
The example of the present invention provides a data transmission processing method, which is used to solve the problems of data loss and the like caused by insufficient relay IPC forwarding capability in the related art, and effectively improve the data transmission efficiency, and fig. 6 is a flowchart of the data transmission processing method according to the example of the present invention. The relay IPC monitors the congestion state of the wifi network, and after the congestion is monitored, the IPC with the lower importance level is preferentially disconnected, so that the IPC with the higher importance level can transmit the video data back to the NVR when the wifi network is congested, and the method comprises the following steps:
step A: when the IPC is in the relay mode, the IPC device supporting the functions of the STA and the AP of wifi forwards the data of other IPCs received by the AP unit 608 to the STA and further to the NVR, judges the data sent by the NVR to the STA unit 604, and forwards the data to the AP unit 608 and further to other IPCs connected to the AP unit 608 if the target is not the IPC device;
and B: the STA unit 604 establishes wifi connection with the NVR or the AP of the relay IPC and receives and transmits data;
and C: the congestion detection unit 606 monitors the network state of the STA unit, and when network congestion is detected, notifies the decision unit 610;
step D: the AP unit 608 establishes wifi connection with the STA units 604 of other IPCs and receives and transmits data;
step E: the decision list 610 is used for extracting the information of the IPC with the lowest importance level from the level management unit 612 and making a decision after receiving the congestion state notified by the congestion monitoring unit 606, stopping the video data transmission if the IPC with the lowest importance level is the IPC with the lowest importance level, and controlling the AP unit 608 to disconnect the wifi connection if the IPC with the lowest importance level is not the IPC with the lowest importance level;
step F: the level management unit 612 is used for persistently storing the importance level of the unit; when the IPC is in relay mode, the importance level of other IPCs connected to the AP of the IPC and identification information thereof are temporarily stored.
In order to better understand the above embodiments, the following further explains the above embodiments, but the invention is not limited to the technical solutions of the embodiments.
1) And (3) classifying the importance levels by using Arabic numerals 1-99, and identifying the importance levels, wherein the smaller the number is, the higher the importance level is, namely 1 identifies the most important part, and 99 identifies the least important part. The importance level of an IPC is generally determined according to the importance of the location monitored by the IPC. There is a better implementation manner, the importance levels are configured according to the monitored positions and time periods, that is, the importance levels of different positions are set differently, and the importance levels of the same position can also be set differently in different time periods, which is exemplified as follows:
position of Time of day Importance level
Parlor 9:00～18:00 1
Parlor 0:00～9:00/18:00～24:00 5
Basement 0:00～24:00 10
In addition, the importance levels of different IPCs may be set to the same value, and when congestion occurs, if the importance levels of all IPCs are the same, the subsequent connection is disconnected first in the order of connection.
2) The congestion state of the wifi network is judged, a buffer area for sending data is monitored, if the data buffered by the buffer area exceeds a certain threshold value, the wifi network is considered to be congested, preferably, in order to prevent misjudgment or over sensitivity caused by network fluctuation, the duration time of the congestion can be counted, and when the duration time also exceeds a certain threshold value, the congestion is judged.
