Detailed Description
To make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the present application will be clearly and completely described below with reference to the drawings in the present application, and it is obvious that the described embodiments are some, but not all embodiments of the present application. 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.
In the prior art, the control behaviors of the remote control data transmission process, the initiation and the termination of the transmission process are all determined by the control equipment. The remote control means that the current control device is another terminal device different from the data transmission/reception device. It will be appreciated that the control device itself is not able to determine the timing of the data transfer and the content of the data transferred. Therefore, the remote control mode is mostly applied to scenes with people participating. And after the user judges the data transmission condition, triggering the control equipment to initiate or end the transmission process.
The inventor finds that in the process of implementing the application, users do not participate in many scenes, but a transmission mode of remote control is still needed. For example, in a road video monitoring scene, a monitoring device is arranged on a road to collect video data. If the control device needs to acquire the video information of the overspeed vehicle in a certain period, the control device can only initiate a data transmission request to the monitoring device at the beginning of the period and initiate a transmission ending request to the monitoring device at the end of the period, so as to acquire the video information in the period. The control device cannot provide accurate demand conditions, and the monitoring device cannot transmit target monitoring videos in a targeted manner. The transmission mode has the advantages of large transmission data flow, more occupied network resources, lower efficiency and obviously incapability of meeting the requirements.
Based on this, the application provides a data transmission method, a system, a control device, a network device and a media device. By adding the data transmission condition and/or the data transmission termination condition in the data transmission request, the media device sends more accurate data information according to the data transmission request, and the data transmission efficiency is improved.
Fig. 1 is an application scenario diagram provided in the present application. As shown in fig. 1, the scheme of the present application can be applied to a scene with a remote control for monitoring video data transmission. The monitoring device 101 is used for providing monitoring video data, and the control device 102 is used for remotely controlling the monitoring device 101 to start or end the transmission process of the media data. The network device 103 provides a network channel for data transmission between the monitoring device 101 and the control device 102. The monitoring device 101 may be a terminal device having image acquisition and/or image processing functions; the control device 102 may be a server, a computer, a mobile phone, or other terminal device; the network device 103 may be a server. The following embodiments may be referred to for specific implementation of the data transmission process.
Fig. 2 is a flowchart of a data transmission method according to an embodiment of the present application. As shown in fig. 2, the method of the present embodiment includes:
s201, the control device determines a data transmission triggering condition.
S202, the control device sends a data transmission request to the network device, wherein the data transmission request comprises a data transmission triggering condition. Correspondingly, the network device receives the data transmission request sent by the control device.
The data transmission trigger condition refers to a condition that triggers the media device to transmit data. The data trigger condition is added to the data transmission request and sent to the network device to cause the network device to forward the data transmission request to the media device. After receiving the data transmission request, the media device may send media data to the network device according to the data transmission trigger condition.
The data transmission triggering condition can be determined by the user according to actual requirements.
In some embodiments, the data transmission request further includes: the identity information of the control equipment and the identity information of the media equipment are used for informing the network equipment of the information of the data transmission requesting party and the data transmission requested party. The network device can determine the transmission direction of the data stream according to the information and further judge the authority of data transmission.
In some embodiments, the network device may determine whether the control device has the control authority according to the data transmission request; and when the control device is determined to be provided with the control right, forwarding the data transmission request to the media device. And if the network equipment determines that the control equipment does not have the control authority, the network equipment does not forward the data transmission request to the media equipment any more. The flow may be ended after feedback to the control device.
S203, the network device forwards a data transmission request to the media device, wherein the data transmission request comprises a data transmission triggering condition. Correspondingly, the media device receives a data transmission request sent by the network device, wherein the data transmission request comprises a data transmission triggering condition.
And S204, the media equipment sends the media data to the network equipment according to the data transmission triggering condition.
The media device may send the corresponding media data to the network device only when the data transmission triggering condition is met by determining whether the data transmission triggering condition is met.
The data transmission trigger condition may be a condition set for the media data. For example, when the media data satisfies a certain condition, the media data satisfying the condition is transmitted to the network device. Specifically, in the process of transmitting the road video monitoring information, the data triggering condition may be that the vehicle speed in the video exceeds a set value. And after the media equipment processes the acquired video data in real time and determines that a certain vehicle is overspeed, the media equipment starts to transmit video information. And when the overspeed vehicle does not exist in the video picture, the transmission of the video is not triggered.
The data transmission method provided by the application comprises the following steps: the control equipment determines a data transmission triggering condition; the control equipment sends a data transmission request to the network equipment, wherein the data transmission request comprises a data transmission triggering condition; the network equipment receives and forwards a data transmission request to the media equipment; and after receiving the data transmission request, the media equipment sends media data to the network equipment according to the data transmission triggering condition. According to the scheme of the application, the data transmission triggering condition is added into the data transmission request, so that the media equipment can transmit the media data according to the triggering of the data transmission triggering condition. The method can more accurately control the start and the end of the transmission process of the media data, reduce the transmission of unnecessary data, save network resources and improve the transmission efficiency of the media data.
In some embodiments, the media device may also need to be acknowledged by the network device before sending the media data to the network device. Specifically, the media device sends a media data sending request to the network device when the data transmission triggering condition is satisfied. Correspondingly, the network equipment receives a media data sending request sent by the media equipment; determining whether to allow the media data to be sent currently or not according to the media data sending request; and if the media data are allowed to be sent currently, sending a media data sending confirmation instruction to the media equipment, wherein the media data sending confirmation instruction is used for indicating that the media data are allowed to be sent currently. Correspondingly, after receiving the media data sending confirmation instruction sent by the network equipment, the media equipment sends the media data to the network equipment.
The network device may be responsible for data transmission of multiple media devices at the same time, but the network resource is limited, and a network congestion condition may exist, which may no longer support the media device to send media data, resulting in transmission failure. Thus, authentication may be performed prior to transmission, and the media device may be notified to transmit after determining that current network conditions permit.
In some embodiments, when the network device determines that media data is currently allowed to be sent, it may also send a data transmission prompt to the control device; to prompt the control device that the data transfer request is responded to by the media device. Correspondingly, the control device receives the data transmission prompt.
In some embodiments, the data transmission request may further include: controlling the time length; the control duration is used to indicate the validity duration of the data transmission request. After receiving the data transmission request, the media equipment starts timing according to the control time length; and sending the media data to the network equipment according to the data transmission triggering condition within the control duration. And after the control duration is finished, ending the data transmission process.
The setting of the control duration can be set by a user according to actual requirements. After the information is added, the media data in a certain time period can be acquired, and the high efficiency of the data transmission process can be further ensured.
It is understood that the data transfer triggering condition may be satisfied a plurality of times within the control duration. And when the data transmission triggering condition is met each time, the media equipment sends a media data sending request to the network equipment. Correspondingly, the network equipment receives a media data sending request sent by the media equipment; determining whether to allow the media data to be sent currently or not according to the media data sending request; and if the media data are allowed to be sent currently, sending a media data sending confirmation instruction to the media equipment, wherein the media data sending confirmation instruction is used for indicating that the media data are allowed to be sent currently. Correspondingly, after receiving the media data sending confirmation instruction sent by the network equipment, the media equipment sends the media data to the network equipment.
In some embodiments, a data transmission termination request may also be sent after the data transmission request is sent.
Specifically, the control device sends a data transmission termination request to the network device, where the data transmission termination request includes a data transmission termination condition. Correspondingly, the network device receives and forwards the data transmission termination request to the media device. Correspondingly, the media device receives the data transmission termination request and stops sending the media data to the network device according to the data transmission termination condition. When the data transmission termination condition is met, the media equipment stops data transmission and sends a data transmission termination prompt to the network equipment; accordingly, the network device receives and forwards a data transmission termination prompt to the control device to prompt the control device that the data transmission termination request has been responded to by the media device.
In some embodiments, after receiving the data transmission termination request, the network device may further determine whether media data in transmission indicated by the data transmission termination request currently exists according to the data transmission termination request; and if the media data in transmission exists, forwarding a data transmission termination request to the media equipment.
The network equipment determines whether the data transmission task exists currently according to the information in the data transmission termination request. If yes, continuing to execute; if not, the process may be ended directly after the feedback.
Fig. 3 is a flowchart of a data transmission method according to another embodiment of the present application, and as shown in fig. 3, the method of the present embodiment includes:
s301, the control equipment determines a data transmission triggering condition and a control time length.
S302, the control device sends a data transmission request to the network device, wherein the data transmission request comprises a data transmission triggering condition and a control duration. Correspondingly, the network device receives the data transmission request sent by the control device.
