Detailed Description

For the purposes of making the objects, technical solutions and advantages of the present application more apparent, 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 apparent that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.

In the prior art, in a data transmission process controlled remotely, the control actions of starting and ending the transmission process are determined by a control device. By remote control is meant that the current control device is a further terminal device, which is different from the data transceiving device. It will be appreciated that the control device itself is not able to determine the timing of the data transmission and the data content of the transmission. Therefore, the remote control mode is widely applied to scenes with participation of people. After the user judges the data transmission condition, the control equipment is triggered to initiate or end the transmission process.

The inventor finds that in the process of implementing the application, there are many scenarios without user participation, but a remote control transmission mode is still needed. For example, in a road video monitoring scene, a monitoring device is disposed on a road, and video data is collected. If the control device needs to acquire the overspeed vehicle video information in a certain period, the control device can only initiate a data transmission request to the monitoring device when the period starts, and initiate a request for ending transmission to the monitoring device when the period ends, so that the video information in the period is acquired. 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 the above, the application provides a data transmission method, a data transmission system, a data transmission 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 can send 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 application can be applied to a scene with a remote control for monitoring video data transmission. The monitoring device 101 is configured to provide monitoring video data, and the control device 102 is configured to remotely control the monitoring device 101 to start or end a transmission process of 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 an image acquisition and/or image processing function; the control device 102 may be a terminal device such as a server, a computer, a mobile phone, etc.; the network device 103 may be a server. Reference is made to the following embodiments for a 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 equipment sends a data transmission request to the network equipment, wherein the data transmission request comprises a data transmission triggering condition. Correspondingly, the network device receives a 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 transfer request and sent to the network device to cause the network device to forward the data transfer request to the media device. After receiving the data transmission request, the media device can send media data to the network device according to the data transmission triggering condition.

The data transmission triggering condition can be determined by a user according to actual requirements.

In some embodiments, the data transmission request may further include: the identity information of the control device and the identity information of the media device are used for informing the network device of the information of the requester for data transmission and the requested party for data transmission. The network device may determine the transmission direction of the data stream according to the information, and further determine the authority of data transmission.

In some embodiments, the network device may determine, according to the data transmission request, whether the control device has control authority; and forwarding the data transmission request to the media device when the control device is determined to have the control right. If the network device determines that the control device does not have control authority, the data transmission request is not forwarded to the media device. The flow may be ended after feedback to the control device.

S203, the network equipment forwards a data transmission request to the media equipment, 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 media data to the network equipment according to the data transmission triggering condition.

The media device may send corresponding media data to the network device by determining whether the data transmission trigger condition is satisfied, and when the data transmission trigger condition is satisfied.

The data transmission trigger condition may be a condition set for 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. The media device starts to transmit video information after determining that a certain vehicle is overspeed after processing the collected video data in real time. And when the overspeed vehicle is not 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 the data transmission request to the media equipment; and the media equipment sends the media data to the network equipment according to the data transmission triggering condition after receiving the data transmission request. According to the scheme, the data transmission triggering condition is added in the data transmission request, so that the media equipment can perform media data transmission according to the triggering of the data transmission triggering condition. The method can more accurately control the start and end of the media data transmission process, reduce unnecessary data transmission, save network resources and improve the media data transmission efficiency.

In some embodiments, confirmation by the network device is also required before the media device sends the media data to the network device. Specifically, when the triggering condition of data transmission is met, the media device sends a media data sending request to the network device. Correspondingly, the network equipment receives a media data sending request sent by the media equipment; determining whether to allow the transmission of the media data currently according to the media data transmission request; and if the media data is 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 the media data to be sent currently. Correspondingly, after receiving the media data transmission confirmation instruction sent by the network device, the media device sends the media data to the network device.

The network device may be responsible for data transmission of multiple media devices at the same time, but network resources are limited, and network congestion may exist, so that the network device cannot be supported to send media data, which results in transmission failure. Thus, authentication may be performed prior to transmission, and the media device may be notified to transmit after determining that the current network conditions are allowed.

In some embodiments, the network device may also send a data transmission hint to the control device when it determines that media data is currently allowed to be sent; to prompt the controlling device that the data transfer request is responded to by the media device. Correspondingly, the control equipment receives the data transmission prompt.

In some embodiments, the data transmission request may further include: controlling the duration; the control duration is used to indicate the effective duration of the data transmission request. After receiving the data transmission request, the media equipment starts timing according to the control duration; 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 over, ending the data transmission process.

The control duration can be set by a user according to actual requirements. After the information is added, the media data in a specific time period can be acquired, and the high efficiency of the data transmission process can be further ensured.

It will be appreciated that the data transmission trigger condition may be satisfied multiple times during the control period. Each time the data transmission trigger condition is satisfied, the media device transmits a media data transmission request to the network device. Correspondingly, the network equipment receives a media data sending request sent by the media equipment; determining whether to allow the transmission of the media data currently according to the media data transmission request; and if the media data is 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 the media data to be sent currently. Correspondingly, after receiving the media data transmission confirmation instruction sent by the network device, the media device sends the media data to the network device.

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 device stops data transmission and sends a data transmission termination prompt to the network device; 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, according to the data transmission termination request, whether there is currently media data in transmission indicated by the data transmission termination request; if the media data in transmission exists, forwarding a data transmission termination request to the media device.

The network device determines whether the data transmission task currently exists according to the information in the data transmission termination request. If yes, continuing to execute; if not, the process can be directly ended after feedback.
