It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
It can be understood that in some large-scale commodity exhibition or science and technology museum exhibition activities, or tourist attraction construction, or street advertisement putting, in order to improve the interest of the construction site, the commodities, exhibits or corresponding advertisement information corresponding to different exhibition areas or areas are usually animated through configured electronic display devices, or broadcasted by voice. In the above audio data display scenario, the server needs to transmit different or the same audio to be played to each corresponding display device in advance through a wireless connection technology.
Or in the terminal express sorting scene in the logistics field, in order to improve the express sorting efficiency, express information destined to the same network point or distributed point can be distributed to the handheld terminal of the sorter through the background server or the distributor.
It can be understood that, in the data distribution process in the above scenario, the control end or the built distributor needs to send data to each receiving device one by one, so that the data transmission cost is high, the data processing capacity of the control end is large, and the data transmission efficiency is low.
In the embodiment of the present application, in order to implement fast distribution of data in the above scenario, a data transmission architecture as shown in fig. 1 is provided. The architecture may include a plurality of receiving devices, and at least one control terminal.
The control end in the data transmission architecture shown in fig. 1 may be a mobile terminal, such as an electronic device with data storage and transmission functions, such as a mobile phone, a tablet computer, or a notebook computer. The receiving device can be a terminal device with data processing capability, such as an electronic receiving device with voice data, image data or audio/video data playing function, such as a display screen or a sound device and other receiving devices; or a hand-held terminal of a sorter of a logistics scene.
For example, in the application scenario described above, the receiving device in fig. 1 may be a playing device with an audio data playing function, and the playing devices configured in different positions or areas play different contents. In the exhibition hall of the science and technology products, the products exhibited in each exhibition area are different. Therefore, the audio data played on the playing device configured for each exhibition area is different. And different or the same audio to be played is transmitted to each corresponding playing device in advance through the configured control end.
The control terminal in the framework is wirelessly connected with each receiving device, and if the control terminal and the receiving devices are connected through a websocket wireless technology, so that the control terminal and the receiving devices are in the same local area network, the control terminal can be connected with the control terminal to send data packets to the receiving device, and the receiving device analyzes the received data packets to execute corresponding operations, such as playing corresponding audio data or displaying express information to be sorted.
It can be understood that, in the embodiment of the present application, the wireless communication mode between the control end and the multiple receiving devices may also adopt other close-range communication modes besides the websocket, and data transmission between the receiving devices and between the control end and the receiving devices may be implemented, which is not limited in this embodiment of the present application.
In the embodiment of the application, when the control end transmits data to different receiving devices, in order to improve the transmission efficiency of the data, each receiving device can be wirelessly connected, so that the receiving device receiving the data packet can be used as a transmitting end, and the data is transmitted to other receiving devices in the same local area network based on a wireless connection technology, so that the data to be transmitted can be efficiently transmitted.
For example, in the exhibition scene of the above-mentioned scientific and technological products, each playing device may be connected to another through the websocket wireless technology, so as to transmit the audio data to be played.
In order to better understand the data transmission method, apparatus, receiving device and medium provided in the embodiments of the present application, detailed descriptions are provided below with reference to fig. 2 to 8.
Fig. 2 is a schematic flowchart of a data transmission method provided in an embodiment of the present application, and as shown in fig. 2, the method may be executed by the receiving device in fig. 1, where the method specifically includes:
s110, a first receiving device receives a data packet sent by a control end or other receiving devices in the same lan as the first receiving device.
S120, the first receiving device parses the data packet.
S130, the first receiving device sends the data packet to a second receiving device based on the parsing result, where the second receiving device is a receiving device that is in the same local area network as the first receiving device and does not receive the data packet.
Specifically, in the embodiment of the present application, by using the receiving device as a data interaction party, all receiving devices located in the same local area network can be used as a data receiving end and also can be used as a data sending end, so as to improve data transmission efficiency. That is, after receiving a data packet to be transmitted, a first receiving device in the architecture shown in fig. 1 may serve as a data transmitting end to transmit the data packet to other receiving devices, such as a second receiving device, in the architecture shown in fig. 1.
The first receiving device may specifically analyze the received data packet, and determine any receiving device capable of receiving the data packet, that is, the second receiving device, according to an analysis result. And further transmitting the received data packet to the determined second receiving device so as to realize data transmission among all the receiving devices in the same local area network.
The first receiving device is any one receiving device located in the same local area network, and the received data packet may be sent by a control end or sent by other receiving devices located in the same local area network, so that each receiving device in the same local area network can serve as a distributor for intermediate transmission, that is, serve as a distributor for data distribution.
The data package may include data to be transmitted, such as audio data to be played, program content such as voice data, picture data, or video disc data.
The data packet may also include an identification of the receiving device. The identification of the receiving device may be a MAC address, an IP address, etc. of the receiving device, which can uniquely determine the identity of the receiving device.
Optionally, the data packet may further include a data transmission policy, a data execution policy, a key, and the like. The specific content in the data packet may be determined according to an actual scene, which is not limited in this application example.
It will be appreciated that when distributing transmission data, the receiving device that is currently transmitting or has already transmitted, i.e. is receiving data or has already received data packets, will not be repeatedly distributed. And, the reception apparatus that has already received the data packet may further transmit the reception apparatus that has not started receiving the data packet at present.
In the embodiment of the application, when data are transmitted to a plurality of receiving devices located in the same local area network, any one receiving device in the local area network can be used as a receiving end to receive the data packet and then can be used as a data transmitting end to transmit the data packet to other receiving devices which do not receive the data packet, so that the data can be rapidly distributed, the data transmission pressure of a control end is reduced, and the data transmission efficiency is improved.
Optionally, in this embodiment of the application, when the first receiving device receives the data packet and sends data to the second receiving device according to an analysis result of the data packet, the data may be specifically implemented by using the analysis result.
The process of sending data to the second receiving device based on the parsing result specifically includes:
s131, the first receiving device establishes a data transmission link with the second receiving device based on the receiving device identification obtained by analysis;
s132, the first receiving device sends the data packet to the second receiving device based on the established data transmission link.
Specifically, after the first receiving device analyzes the received data packet to obtain the content in the data packet, a link may be established with the second receiving device according to the identifier of the receiving device included in the analysis result, and then the data packet is sent to the second receiving device after the link is established.
For example, in a product display scenario, when a certain playback device that receives a data packet is used as a data sending end to distribute data, based on a wireless communication mechanism, a data transmission link may be established with a receiving end, that is, a second receiving device, and then the established link may be used to perform data transmission.
Optionally, when establishing a data transmission link with the second receiving device, the method may be performed by using the method shown in fig. 3, and specifically includes:
s01, the first receiving device sends a data transmission link request message to the second receiving device based on the identified rank order.
S02, the first receiving device receives the first feedback message of the second receiving device.
S03, when the first feedback message indicates that the second receiving device does not receive the data packet or does not establish a data transmission link with other receiving devices, the first receiving device establishes a data transmission link with the second receiving device.
Specifically, after the first receiving device analyzes the data packet, the first receiving device may obtain other contents, such as an identifier, an asymmetric key, and the like, of all receiving devices that need to receive the data packet, which are included in the data packet. And then according to the arrangement sequence of the identifiers of the receiving devices, the receiving device corresponding to one identifier is used as a transmission object, namely the second receiving device, so as to establish a data transmission link. I.e. a data transfer link acknowledgement message is generated and sent to the second receiving device. After receiving the data transmission link confirmation message, the second receiving device can send a feedback message to the first receiving device based on the current state of the second receiving device.
And when the second receiving equipment does not receive the data packet currently and does not establish the data transmission link with other receiving equipment and the control end, sending a feedback message to the first receiving equipment to indicate that the data transmission link can be established.
At this time, the first receiving device may transmit a link establishment message to the second receiving device to establish a data transmission link with the second receiving device.
Or, when the second receiving device has received the data packet, or a connection is currently established at the control end or other receiving devices for data transmission, a message is fed back to the first receiving device to indicate that the first receiving device is not required to transmit the data packet.
At this time, the first receiving device may return to the step of S131, and re-determine a receiving device corresponding to the receiving device identifier from the identifiers of the receiving devices, as a transmission object, that is, a third receiving device, to establish a data transmission link, and repeat the above operations.
It is to be understood that the third receiving device is also a receiving device in the same local area network as the first receiving device and the second receiving device.
Optionally, in some embodiments, all fields of the identifiers of the receiving devices may be sequentially stored in the corresponding data packets. For example, the identifiers of all playback devices in a certain product display area may be encapsulated in a data packet according to a certain sequence.
It can also be understood that, in this embodiment of the application, since all receiving devices in the same local area network may serve as both a receiving end and a data sending end, in the data distribution process, the first receiving device may also receive a data transmission link request message sent by another receiving device.
Namely, the method may further comprise:
s06, the first receiving device receives the data connection request sent by the fourth receiving device.
S07, the first receiving device sends a second feedback message to the fourth receiving device, where the second feedback message indicates that the first receiving device has received the data packet.
Specifically, the first receiving device may also receive a data connection request sent by another receiving device, such as a fourth receiving device, in the same local area network while distributing data to the other receiving device, so as to send data to the first receiving device.
It can be understood that, since the first receiving device has currently acquired the data packet, a second feedback message indicating that it has received the data packet may be sent to the fourth receiving device.
It can also be understood that, in this embodiment of the application, after the receiving devices corresponding to the identifiers of all the receiving devices encapsulated in the data packet acquire the data packet, that is, all the feedback messages indicate that the data packet has been currently received, or the data packet is currently connected to other receiving devices or a control end for data transmission connection, the method ends.
In the embodiment of the application, the display device which obtains the data to be displayed is connected with other display devices, and the obtained audio data to be displayed is transmitted to the display device which is connected with the display device, so that a data transmission path is formed between the display devices, the data processing pressure of the control terminal is reduced, and the data transmission efficiency is finally improved.
On the other hand, as shown in fig. 4, an embodiment of the present application further provides a data transmission method, where the method is executed by a control end, and specifically includes:
s210, the control end sends a data transmission message to the first receiving device;
s220, the control end receives a feedback message of the first receiving device;
s230, when the feedback message indicates that the first receiving device does not receive a data packet or does not establish a data transmission link with other receiving devices in the same local area network, the control end sends a data packet to the receiving device.
Specifically, after the data packet to be transmitted is loaded on the control end, for example, after the data packet to be transmitted is acquired from the server or acquired in other manners, a connection may be established with the first receiving device in the same local area network that needs to receive the data packet, and the data packet is transmitted to the first receiving device that establishes the connection.
For example, when the control end establishes a link with the receiving device, the control end may recognize a barcode or a two-dimensional code including an identifier of the receiving device.
It can be understood that, according to the above embodiment, after receiving the data packet, the first receiving device may serve as a data sending end to transmit the data packet to other receiving devices that do not receive the data packet.
It is also understood that the first receiving device is any receiving device within the same lan as the control terminal that needs to receive the data packet. After the first receiving device completes the data packet transmission, the first receiving device may continue to establish a data transmission link with other receiving devices in the same local area network, so as to continue to transmit data to other receiving devices. Namely, the control end and the receiving equipment receiving the data packet are both used as data sending ends to distribute the data packet, and the method is ended until the receiving equipment corresponding to all the identifiers in the data packet receives the data packet.
Optionally, in order to better understand data transmission between all receiving devices in the same local area network in the embodiment of the present application, the following is illustrated and explained by using the scenario shown in fig. 5.
For example, in a product display scenario, for a data packet of a certain product, the identifiers of the receiving devices included in the data packet are the identifiers of the receiving devices of all display devices in the product display area.
If 12 playback devices, such as 10 display screens, are included in the same lan. Moreover, the No. 1-7 display screens are positioned in the same exhibition area, the No. 8-10 display screens are positioned in the same exhibition area, and the No. 11 and No. 12 display screens are positioned in the same exhibition area. That is, display screens 1-7 play the same audio data, display screens 8-10 play the same audio data, and display screens 11 and 12 play the same audio data.
The audio data that can be sent to the display screen at the control end includes three data packets, and the first data packet may include audio data to be played of display screens No. 1-7 and identifiers of display screens No. 1-7 sequentially arranged in sequence; the second data packet can include audio data to be played of No. 8-10 display screens and identifications of No. 8-10 display screens sequentially arranged in sequence; the third data packet may include audio data to be played for display screens No. 11 and No. 12, and identifiers of display screens No. 11 and No. 12 sequentially arranged in sequence.
Further, if after the display screen 1 receives the first data packet sent by the control terminal, it can be known that the data packet can also be sent to the display screen 2-7 by parsing. At this time, the display screen No. 1 may use the display screen No. 2 as a second receiving device, that is, a target receiving device, to prepare for transmitting data to the display screen No. 2, according to the arrangement sequence of the identification field of the receiving device of the display screen in the data packet, if the identification field of the display screen No. 1 is followed by the identification field of the display screen No. 2.
First, the display screen No. 1 may generate a data transmission connection request message based on the identifier of the display screen No. 2, and send the message to the display screen No. 2.
Further, after receiving the request message sent by the display screen 1, the display screen 2 can reply a feedback message to the display screen 1 according to the current state of the display screen.
It can be understood that, since the display screen No. 1 completes the reception of the data packet, that is, the control end completes the transmission of the data packet to the display screen No. 1. A connection may be further established with display screen No. 2 to distribute the data package to display screen No. 2.
Therefore, if the display screen 2 receives the request message sent by the control terminal first, the message fed back to the control terminal indicates that the establishment of the data transmission link is confirmed, so as to achieve the acquisition of the data packet. Correspondingly, since the No. 2 display screen is ready to establish a data transmission link with the control terminal, the message fed back to the No. 1 display screen indicates that the link establishment is refused.
Alternatively, in other embodiments, the display screen No. 2 may not feed back any messages to the first receiving device.
Then, when the first receiving device, that is, the display screen No. 1, does not receive the feedback message of the second receiving device within the preset time period, or receives a message indicating that the link establishment is rejected, which is fed back by the second receiving device, the first receiving device returns to S131, that is, establishes a data transmission link with another receiving device according to the identifier.
As shown in fig. 5, after the display screen No. 1 does not receive the feedback message of the display screen No. 2 in the preset time period or receives the feedback message indicating that the link establishment is rejected, further, according to the analyzed identifier of the receiving device, the display screen No. 3 is used as a second receiving device, that is, a target transmission object, in sequence, and the above actions are repeated. At this time, since the display screen No. 3 does not receive the data packet, a confirmation message that the data transmission link can be established can be fed back to the display screen No. 1. After receiving the feedback message, the display screen 1 can establish a data link with the display screen 3, and complete the transmission of the data packet.
Further, after the data packet is received by the display screen No. 3, the data packet and the display screen No. 1 can be used as a data sender at the same time, and the same action as the display screen No. 1 is executed, that is, the display screen No. 1 and the display screen No. 2 can try to perform data interaction with the display screen No. 4, so as to establish a data transmission link. In the process, the No. 4 display screen can establish a data transmission link with a sender of the first received request message, if the request message of the No. 1 display screen is received first, the No. 4 display screen is connected with the No. 1 display screen, the No. 3 display screen can continue to perform data interaction with the No. 5 display screen, and when the No. 5 display screen does not receive the data packet and is not connected with other terminals, such as the No. 5 display screen does not have other display screens and a control terminal, the data transmission link can be established and data transmission is performed.
Further, after receiving the data packet, the display screen 1-5 may continue to serve as a data sending end to send the data packet to other display screens, for example, the display screen 1-5 that receives the data packet tries to establish a connection with the display screen 6 and the display screen 7, so as to distribute the data.
In the process, after the control end completes the data packet distribution of the display screen No. 2, the control end can continue to establish data transmission links to other display screens to distribute the data packets.
And finally, all the display screens No. 1-7 in the same exhibition area receive the data packets so as to complete data sharing among all the receiving devices.
It can be understood that, for the other two groups of display screens shown in fig. 5, i.e. display screens No. 8-10 and display screens No. 11-12, which play the same audio data, the above-mentioned splitting distribution mode can also be adopted to quickly achieve the acquisition of the audio data.
According to the data transmission method provided by the embodiment of the application, each receiving device can be used as a distributor through data interaction between the receiving devices in the same local area network, and the data packets are automatically and synchronously transmitted to the screen-side receiving device which is not yet transmitted in a plan. In the transmission process, the control end and the screen end realize the distribution of the data packets in the 1-N mode, and the screen end adopt the distribution of the data packets in the N-N mode.
