Detailed Description

In order that the above objects, features and advantages of the present disclosure may be more clearly understood, aspects of the present disclosure will be further described below. It should be noted that the embodiments and features of the embodiments of the present disclosure may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may be practiced in other ways than those described herein; it is to be understood that the embodiments disclosed in the specification are only a few embodiments of the present disclosure, and not all embodiments.

Fig. 1 is a block diagram of a data transmission system according to an embodiment of the present disclosure. Fig. 2 is a flowchart of a data transmission method according to an embodiment of the present disclosure. The data transmission method provided by the present disclosure can be applied to the application environment shown in fig. 1. Referring to fig. 1, the data transmission system includes a cloud server, a first gateway, a second gateway, and a plurality of smart home devices. And one part of the intelligent household equipment is in communication connection with the first gateway through the network, and the other part of the intelligent household equipment is in communication connection with the second gateway through the network. Exemplarily, in fig. 1, an intelligent home device 1 and an intelligent home device 2 are connected to a first gateway through network communication; the intelligent household equipment 3 is in communication connection with the second gateway through a network. The first gateway and the second gateway are in communication connection with the cloud server through a network.

The cloud server can be implemented by an independent server or a server cluster consisting of a plurality of servers. Smart home devices may include, but are not limited to, various personal computers, notebook computers, smart phones, tablet computers, portable wearable devices, smart screens, cameras, file storage, electric cookers, microwave ovens, air conditioners, table lamps, sockets, televisions, refrigerators, washing machines, dish washers, and stereos.

For example, in fig. 1, a first gateway and a second gateway may be bridged, and a local area network is jointly established by the first gateway and the second gateway, so that the smart home devices 1, 2, and 3 are located in the same local area network, which is referred to as a cascading case. The first gateway and the second gateway can also be used for respectively establishing local area networks, so that the intelligent home equipment 1 and the intelligent home equipment 2 are located in the same local area network, the intelligent home equipment 3 and the intelligent home equipment 1 are located in different local area networks, and the intelligent home equipment 3 and the intelligent home equipment 2 are located in different local area networks, which is called as a non-cascading situation.

In fig. 2, the data transmission method is executed by the smart home device. Exemplarily, if two local area networks are established by using a first gateway and a second gateway respectively, when the smart home device 1 needs to perform data transmission with the smart home device 2, the smart home device 1 obtains a data transmission instruction; and determining whether the intelligent household equipment 1 and the intelligent household equipment 2 are in the same local area network or not based on the information of the intelligent household equipment 1 and the information of the intelligent household equipment 2 in the data transmission instruction. Because the intelligent household equipment 1 and the intelligent household equipment 2 are located in the same local area network, the intelligent household equipment 1 and the intelligent household equipment 2 are controlled to perform data transmission based on the local area network. If the intelligent home equipment 1 needs to perform data transmission with the intelligent home equipment 3, the intelligent home equipment 1 acquires a data transmission instruction; and determining whether the intelligent household equipment 1 and the intelligent household equipment 3 are in the same local area network or not based on the information of the intelligent household equipment 1 and the information of the intelligent household equipment 3 in the data transmission instruction. Because the intelligent home devices 1 and 3 are not in the same local area network, the intelligent home devices 1 and 3 are controlled to perform data transmission based on the cloud server.

Alternatively, the method may be performed by a data transmission device, which may be implemented in software and/or hardware, and the device may be configured in the smart home device. As shown in fig. 2, the method may specifically include:

s110, acquiring a data transmission instruction, wherein the data transmission instruction comprises sending equipment information and receiving equipment information.

In practice, in the same data transmission system, the sending device and the receiving device are not fixed, but dynamically change according to the data transmission situation. For example, referring to fig. 1, it is assumed that the smart home device 1 is a mobile terminal, such as a mobile phone, and the smart home device 2 is a television. When a user wants to use the mobile terminal to project a certain video on a television, the smart home device 1 is a sending device and the smart home device 2 is a receiving device for the video to be projected. If in another situation, if the user uses the mobile terminal to project a certain video on the television, but the screen projection fails, and the television feeds back the prompt information of the screen projection failure to the mobile terminal, the smart home device 2 is a sending device and the smart home device 1 is a receiving device for the prompt information to be fed back. Therefore, referring to fig. 1, in practice, any one smart home device may be a sending device and may also be a receiving device. When the data transmission method provided by the present disclosure is executed, the determination needs to be made according to actual conditions.

The sending device information includes sending device identification information and/or identification information of a gateway connected with the sending device. The sending device identification information is information which can uniquely distinguish the sending device from other intelligent household devices which are connected with the same cloud server with the sending device. Illustratively, the transmitting device identification information includes, but is not limited to, at least one of: a sending device hardware ID, a sending device MAC address, a sending device IP address, a sending device name, and a sending device model. The identification information of the gateway connected to the transmission device is information that can uniquely distinguish the gateway connected to the transmission device from other gateways. Illustratively, the identification information of the gateway connected to the sending device includes: at least one of a MAC address and an SSID number of a gateway connected with the transmitting device.

Similarly, the reception device information includes reception device identification information and/or identification information of a gateway connected to the reception device. Wherein the receiving device identification information includes but is not limited to at least one of the following: a receiving device hardware ID, a receiving device MAC address, a receiving device IP address, a receiving device name, and a receiving device model. Identification information of a gateway connected to the receiving device, including: at least one of a MAC address and an SSID number of a gateway connected with the receiving device.

The data transmission instruction is generated based on a user operation. Illustratively, an application program for adjusting the working state of the receiving device is installed in the sending device (such as a mobile phone). And the user generates a data transmission instruction by operating the application program. The receiving equipment receives and executes the data to be transmitted in the data transmission instruction so as to realize the adjustment of the working state.

And S120, determining whether the sending device and the receiving device are in the same local area network or not based on the sending device information and the receiving device information.

There are various implementation methods of this step, and optionally, it is determined whether the sending device and the receiving device are in the same local area network based on the identification information of the gateway connected to the sending device and the identification information of the gateway connected to the receiving device. This method is suitable for non-cascaded cases.

Illustratively, if the identification information of the gateway connected to the transmitting device includes the MAC address of the gateway connected to the transmitting device, the identification information of the gateway connected to the receiving device includes the MAC address of the gateway connected to the receiving device, and it is determined whether the transmitting device and the receiving device are within the same local area network based on the MAC address of the gateway connected to the transmitting device and the MAC address of the gateway connected to the receiving device. If the two MAC addresses are the same, determining that the sending equipment and the receiving equipment are connected with the same gateway and are in the same local area network; and if the two MAC addresses are different and the same, determining that the sending equipment and the receiving equipment are not in the same local area network.

Or, if the identification information of the gateway connected to the sending device includes the SSID number of the gateway connected to the sending device, and the identification information of the gateway connected to the receiving device includes the SSID number of the gateway connected to the receiving device, determining whether the sending device and the receiving device are connected in the same local area network based on the SSID number of the gateway connected to the sending device and the SSID number of the gateway connected to the receiving device. If the two SSID numbers are the same, determining that the sending equipment and the receiving equipment are connected with the same gateway and are positioned in the same local area network; and if the two SSID numbers are different and the same, determining that the sending equipment and the receiving equipment are in different local area networks.

Or, if the identification information of the gateway connected to the sending device includes: the MAC address and SSID number of the gateway connected with the sending device; the identification information of the gateway connected to the receiving device includes: the MAC address and SSID number of the gateway connected with the receiving device; based on the two MAC addresses and the two SSID numbers, it is determined whether the transmitting device and the receiving device are in the same local area network. If the two MAC addresses and the two SSID numbers are the same, determining that the sending equipment and the receiving equipment are connected with the same gateway and are positioned in the same local area network; otherwise, the sending equipment and the receiving equipment are determined to be in different local area networks.

It should be noted that, for the receiving device information, only the receiving device identification information is included, and the identification information of the gateway connected to the receiving device is not included; and/or in the case where the sending device information includes only the sending device identification information and does not include the identification information of the gateway connected to the sending device, optionally, the identification information of the gateway connected to the receiving device and the identification information of the gateway connected to the sending device may be determined by means of the device information list. The device information list is stored in the cloud server and comprises identification information of all devices in communication connection with the cloud server and identification information of gateways connected with the devices.

Exemplarily, if in the data transmission instruction, the sending device information includes identification information of a gateway connected to the sending device, and the receiving device information includes identification information of the receiving device; this step can be replaced by: determining identification information of a gateway connected with the receiving device based on the identification information of the receiving device and the device information list; and determining whether the sending device and the receiving device are connected with the same gateway and are in the same local area network based on the identification information of the gateway connected with the sending device and the identification information of the gateway connected with the receiving device. The method is suitable for the condition that the receiving equipment information comprises the identification information of the gateway connected with the receiving equipment in the data transmission instruction, and is also suitable for the condition that the receiving equipment information does not comprise the identification information of the gateway connected with the receiving equipment in the data transmission instruction.

Optionally, the implementation method in this step may further be that, based on the public network IP of the sending device and the public network IP of the receiving device, it is determined whether the sending device and the receiving device are in the same local area network. The method is suitable for the non-cascading condition and the cascading condition.

Exemplarily, if the sending device information includes sending device identification information in the data transmission instruction, the sending device identification information includes a sending device public network IP; the receiving device information includes receiving device identification information; this step can also be replaced by: determining a public network IP of the receiving equipment based on the identification information of the receiving equipment and the equipment information list; in the device information list, the identification information of all devices comprises the public network IP of the devices; and determining whether the sending equipment and the receiving equipment are in the same local area network or not based on the public network IP of the sending equipment and the public network IP of the receiving equipment. In the above technical scheme, the device information list may be stored in the sending device, or may be stored in the cloud server. The device information list is stored in the cloud server, and timely maintenance of the device information list can be achieved. The method is suitable for the condition that the identification information of the receiving equipment in the data transmission instruction comprises the public network IP of the receiving equipment, and is also suitable for the condition that the identification information of the receiving equipment in the data transmission instruction does not comprise the public network IP of the receiving equipment.

And S130, if the sending device and the receiving device are in the same local area network, controlling the sending device and the receiving device to perform data transmission based on the local area network.

And S140, if the sending device and the receiving device are not in the same local area network, controlling the sending device and the receiving device to perform data transmission based on the cloud server.

The essence of the technical scheme is that when data transmission is needed, whether conditions for data transmission based on the local area network exist between the sending equipment and the receiving equipment is judged, and if yes, data transmission is carried out based on the local area network; otherwise, data transmission is carried out based on the cloud server. The data transmission can simultaneously have respective advantages of cloud connection and local area network connection by the aid of the arrangement, and the data transmission effect is optimal. Specifically, if the transmitting device and the receiving device have a condition for data transmission via the local area network, and preferentially use the local area network for data transmission, the advantages of low connection delay and high transmission performance of the local area network can be enjoyed. If the sending equipment and the receiving equipment do not have the condition of data transmission based on the local area network, cloud connection transmission is facilitated, and the advantages of good cloud connection stability and no region limitation can be enjoyed.

Through the technical scheme, the user can carry out interconnection and mutual control among different intelligent household equipment at any time and any place, the use cost of flow and cloud server bandwidth is reduced, and the transmission efficiency and quality are improved in the application scene of large data volume transmission.

Here, disconnection refers to disconnection of a connection established for data transmission, including disconnection of a local area network connection and a cloud connection.

Fig. 4 is a schematic diagram of information interaction among the sending device, the receiving device, and the cloud server when the data transmission method in fig. 3 is executed. Fig. 3 is a specific example of fig. 2, and the technical scheme in fig. 3 is applicable to the non-cascaded case. Referring to fig. 3 and 4, the data transmission method includes:

Specifically, the device information list includes a plurality of device information, and the device information corresponds to the smart home devices in communication connection with the cloud server one to one. Each device information includes: the identification information of the intelligent home equipment and the identification information of the gateway connected with the intelligent home equipment.

And updating the equipment information list in real time, wherein the equipment information list comprises at least one of identification information of the intelligent household equipment in the equipment information, identification information of a gateway connected with the intelligent household equipment and whether the intelligent household equipment is in online state or not.

The method for updating the device information list in real time by the cloud server is various, and exemplarily, the cloud server periodically acquires heartbeat packet data of all devices in communication connection with the cloud server; and the cloud server updates the equipment information list based on the heartbeat packet data.

Optionally, before the device is normally offline (e.g., shutdown of the device), the device in communication connection with the cloud server may be actively configured to send a logout instruction to the cloud server, and the cloud server updates the device information list in real time based on the logout instruction, for example, changes the on-line status information of the smart home device to offline.

Optionally, the device connected to the cloud server in communication may be set to be offline abnormally (for example, the device is powered off, the network is disconnected, and the like), the server does not receive heartbeat packet data within a preset time period (for example, within 1 minute), and the cloud server updates the device information list, for example, changes the online status information of the smart home device to offline.

Further, the non-streaming media can be divided into control signaling data and non-control signaling data according to whether the non-streaming media is the control signaling data. The control signaling data refers to data for controlling the receiving device to adjust the operating state, such as data for controlling the receiving device to turn off.

Furthermore, non-control signaling data can be divided into high-flow overhead data and low-flow overhead data according to the size of the occupied space of the data. The high-flow overhead data refers to data which occupies a large space and needs to consume a large amount of flow in transmission, such as picture data, audio data, compressed files and the like.

And S142, controlling the sending equipment and the receiving equipment to transmit data based on the cloud server and the data type of the data to be transmitted.

The essence of this step is that a data transmission strategy is selected in a targeted manner based on the data type of the data to be transmitted. Exemplarily, if the data type of the data to be transmitted is streaming media; when executing the step, adjusting the code rate of the streaming media so that the compression ratio of the streaming media after adjustment is higher than that of the streaming media before adjustment; and controlling the sending equipment to transmit the adjusted streaming media to the receiving equipment based on the cloud server. Optionally, adjusting the streaming media bitrate comprises adjusting one or more of a sharpness, a resolution, and a frame rate of the streaming media. Because the transmission stream media consumes more flow, the flow consumption can be reduced by adjusting the code rate of the stream media, so that the operation cost of the cloud server is reduced, and the cost of users is reduced.

Optionally, if the type of the data to be transmitted is high-traffic overhead data in the non-control signaling data, the data to be transmitted is limited from being transmitted between the sending device and the receiving device.

And if the type of the data to be transmitted is control signaling type data, allowing the data to be transmitted between the sending equipment and the receiving equipment.

Due to the fact that data transmission is carried out based on the cloud server, flow overhead is brought, and the operation cost of the cloud server is increased. The essence of the technical scheme is that a data transmission strategy is reasonably selected according to the data type of data to be transmitted, the flow pressure of the cloud server is reduced, and the operation cost of the cloud server is controlled.

On the basis of the above technical solutions, optionally, if data transmission is performed based on a local area network, the type of the data to be transmitted may be set as a streaming media; adjusting the code rate of the streaming media to ensure that the compression ratio of the streaming media after adjustment is lower than that of the streaming media before adjustment; and controlling the sending equipment to transmit the adjusted streaming media to the receiving equipment based on the cloud server. The definition of the streaming media content can be improved and the use experience of the user is improved.
