Therefore, the problem that data transmission cannot be carried out among slave devices in the traditional technology is effectively solved, and quick data transmission among a plurality of Bluetooth devices is realized.
In order to better understand the above technical solutions, the following detailed description will refer to the accompanying drawings and specific embodiments.
Referring to fig. 2, in a first embodiment of the present application, the bluetooth-based data transmission method of the present application is applied to an intelligent system, and specifically includes the following steps:
in step S110, when at least three bluetooth devices are detected, connection is established with at least three bluetooth devices, respectively, and the type of each bluetooth device is obtained.
In this embodiment, the smart system may be a system composed of at least part of hardware structures of a smart tv or other bluetooth devices, and may be used to implement fast data transmission between two bluetooth devices. The Bluetooth device can be a device with Bluetooth function and data transmission requirement, such as a smart television, a mobile terminal, a Bluetooth headset, a Bluetooth sound box and the like.
When only two Bluetooth devices need to perform data transmission, only one of the Bluetooth devices is required to be used as a main device, and then connection is established between the two Bluetooth devices, so that the data transmission between the two Bluetooth devices can be realized. However, when there are at least three bluetooth devices that need to perform data transmission between two bluetooth devices, no matter which bluetooth device is used as the master device to establish a connection network between bluetooth devices, only data transmission between two bluetooth devices can be partially implemented. Therefore, the application selects the intelligent system as the main equipment of the Bluetooth equipment connection network, takes other Bluetooth equipment needing to carry out data transmission between every two as the auxiliary equipment, and then takes the intelligent system as the transfer station to realize the data transmission between every two of the Bluetooth equipment.
When at least three bluetooth devices are detected, namely when at least three bluetooth devices need to perform data transmission between every two, the intelligent system needs to be respectively connected with at least three bluetooth devices, namely a bluetooth device connection network taking the intelligent system as a master device and at least three bluetooth devices as slave devices is established. After establishing a connection with at least three bluetooth devices, the type of each bluetooth device also needs to be acquired in order to determine the data type of the data that may need to be transmitted between each bluetooth device according to the type of each bluetooth device.
And step S120, establishing indirect connection between every two Bluetooth devices in at least three Bluetooth devices, and determining a data transmission mode between any two Bluetooth devices according to the type of each Bluetooth device.
In this embodiment, after the connection is established with at least three bluetooth devices, the intelligent system may establish indirect connection between two bluetooth devices. For example, if at least three bluetooth devices include bluetooth device a, bluetooth device B, and bluetooth device C, indirect connections between bluetooth device a and bluetooth device B, bluetooth device a and bluetooth device C, and bluetooth device B and bluetooth device C need to be established. The indirect connection is a connection relationship between Bluetooth devices taking the intelligent system as an intermediate node.
The data transfer mode may be a video data transfer mode or a picture data transfer mode or an audio data transfer mode. And the data transmission mode can be other data transmission modes according to the data type of the data which the Bluetooth device needs to transmit in the actual situation. After establishing the indirect connection between every two of the at least three bluetooth devices, the intelligent system can determine a data transmission mode between the bluetooth devices establishing the indirect connection according to the device type of each bluetooth device. For example, if the bluetooth device for establishing the indirect connection is a smart phone or a bluetooth headset, it may be known that data to be transmitted between the bluetooth devices for establishing the indirect connection is audio data, so that it may be determined that a data transmission mode between the bluetooth devices for establishing the indirect connection is an audio data transmission mode; if the bluetooth device for establishing the indirect connection is a smart phone or a tablet computer, it can be known that the data to be transmitted between the bluetooth devices for establishing the indirect connection may be video data or audio data or picture data, so that it can be determined that the data transmission mode between the bluetooth devices for establishing the indirect connection is a video data transmission mode or an audio data transmission mode or a picture data transmission mode.
In step S130, when data transmission is performed between the bluetooth device a and the bluetooth device B, data related information of the bluetooth device a is obtained, and a maximum transmission time for data transmission between the bluetooth device B and the intelligent system is calculated according to the data related information.
In this embodiment, when data transmission is performed between the bluetooth device a and the bluetooth device B, the intelligent system needs to acquire data related information of the bluetooth device a so as to determine a data transmission rate between the bluetooth device B and the intelligent system, thereby further calculating a maximum transmission time for data transmission between the bluetooth device B and the intelligent system. The Bluetooth device A and the Bluetooth device B are any one of at least three Bluetooth devices, the Bluetooth device A is a source device, and the Bluetooth device B is a receiving device. And the data-related information may include a picture format or video resolution or audio format. By calculating the maximum transmission time of data transmission between the Bluetooth device B and the intelligent system, the intelligent system can be prevented from transmitting data exceeding the maximum buffer capacity of the data of the Bluetooth device B when transmitting the data to the Bluetooth device B, so that the data loss caused by overflow of the transmitted data is avoided.
In step S140, data is received from the bluetooth device a, and the received data is sent to the bluetooth device B when the received data reaches a preset size.
In this embodiment, when data transmission is performed between the bluetooth device a and the bluetooth device B, the intelligent system first needs to receive data from the bluetooth device a, and then sends the received data to the bluetooth device B. The time for sending the received data to the bluetooth device B should be less than or equal to the maximum transmission time, so as to avoid sending data exceeding the maximum buffer capacity of the data of the bluetooth device B, thereby avoiding the loss of the transmitted data caused by overflow of the transmitted data. Further, the step of transmitting the received data to the bluetooth device B may be set such that the transmission is started when the received data reaches a preset size. The preset size is set according to actual needs, for example, may be set as a data amount of corresponding data that can be sent by the intelligent system in one second.
The method has the beneficial effects that the intelligent system is used as the main equipment of the Bluetooth connection network, a plurality of Bluetooth equipment needing to carry out data transmission is used as the auxiliary equipment of the Bluetooth connection network, and then the intelligent system is used as the transfer station of the data transmission to realize the technical scheme of data transmission between every two of the plurality of Bluetooth equipment. Therefore, the problem that data transmission cannot be carried out among slave devices in the traditional technology is effectively solved, and quick data transmission among a plurality of Bluetooth devices is realized.
Referring to fig. 3, in a second embodiment of the present application, the bluetooth-based data transmission method of the present application is applied to an intelligent system, and specifically includes the following steps:
in step S210, when at least three bluetooth devices are detected, connection is established with at least three bluetooth devices, respectively, and the type of each bluetooth device is obtained.
Step S211, obtain the name and unique identity of each bluetooth device.
In this embodiment, the name and unique identity of each bluetooth device are used to uniquely identify each bluetooth device. By acquiring the name and the unique identity of each Bluetooth device, a plurality of Bluetooth devices can be better distinguished, so that indirect connection between every two Bluetooth devices can be better established.
In step S220, indirect connection between every two bluetooth devices is established, and a data transmission mode between any two bluetooth devices is determined according to the type of each bluetooth device.
In step S231, when data transmission is performed between the bluetooth device a and the bluetooth device B, data related information of the bluetooth device a is obtained.
Step S232, obtaining the data transmission rate between the Bluetooth device B and the intelligent system according to the data related information, and dividing the data transmission rate by the maximum buffer capacity of the Bluetooth device B to obtain the maximum transmission time for data transmission between the Bluetooth device B and the intelligent system.
In this embodiment, the data transmission rate between the bluetooth device B and the intelligent system may be obtained according to the data related information, and then the maximum data transmission time between the bluetooth device B and the intelligent system may be obtained by obtaining the maximum data buffer capacity of the bluetooth device B and dividing the maximum data buffer capacity of the bluetooth device B by the data transmission rate between the bluetooth device B and the intelligent system. The transmission time of data transmission between the Bluetooth device B and the intelligent system is controlled within the maximum transmission time, so that the intelligent system can be prevented from sending data exceeding the maximum buffer capacity of the data of the Bluetooth device B to the Bluetooth device B, and the data loss caused by overflow of the transmitted data can be avoided.
In step S233, if the data transmission mode is the video data transmission mode, the size, resolution and frame rate of the video data to be transmitted between the bluetooth device a and the bluetooth device B are obtained, and the data stream of the video data is set according to the size, resolution and frame rate of the video data.
In this embodiment, if the determined data transmission mode is the video data transmission mode, it means that the data to be transmitted between the bluetooth device a and the bluetooth device B is video data, and at this time, the size, resolution and frame rate of the video data to be transmitted need to be acquired, and the data stream of the video data is set by using the size, resolution and frame rate of the video data.
In step S234, if the data transmission mode is the picture data transmission mode, the size of the picture data to be transmitted between the bluetooth device a and the bluetooth device B is obtained, and the data stream of the picture data is set according to the size of the picture data.
In this embodiment, if the determined data transmission mode is the picture data transmission mode, it means that the data to be transmitted between the bluetooth device a and the bluetooth device B is the picture data, and at this time, the size of the picture data to be transmitted needs to be acquired, and the data stream of the picture data is set by using the size of the picture data.
In step S235, if the data transmission mode is the audio data transmission mode, the size of the audio data to be transmitted between the bluetooth device a and the bluetooth device B is obtained, and the data stream of the audio data is set according to the size of the audio data.
In this embodiment, if the determined data transmission mode is the audio data transmission mode, it means that the data to be transmitted between the bluetooth device a and the bluetooth device B is audio data, and at this time, the size of the audio data to be transmitted needs to be obtained, and the data stream of the audio data is set by using the size of the audio data.
In step S240, data is received from the bluetooth device a, and the received data starts to be transmitted to the bluetooth device B when the received data reaches a preset size.
The method has the advantages that the step of acquiring the unique identifier of the Bluetooth device and the step of setting the data stream are added on the basis of the first embodiment, and the step of calculating the maximum transmission time is thinned. Therefore, the problem that data transmission cannot be carried out among slave devices in the traditional technology is further effectively solved, and quick data transmission among a plurality of Bluetooth devices is realized.
Referring to fig. 4, in a third embodiment of the present application, the bluetooth-based data transmission method of the present application is applied to an intelligent system, and specifically includes the following steps:
in step S310, when at least three bluetooth devices are detected, connection is established with at least three bluetooth devices, respectively, and the type of each bluetooth device is obtained.
In step S320, indirect connection between every two bluetooth devices is established, and a data transfer mode between any two bluetooth devices is determined according to the type of each bluetooth device.
In step S330, when data transmission is performed between the bluetooth device a and the bluetooth device B, data related information of the bluetooth device a is obtained, and a maximum transmission time for data transmission between the bluetooth device B and the intelligent system is calculated according to the data related information.
In step S340, data is received from the bluetooth device a, and the received data is started to be transmitted to the bluetooth device B when the received data reaches a preset size.
Step S350, the data that has been transmitted is read, and the data that has been transmitted is displayed.
In this embodiment, after transmitting the data received from the bluetooth device a to the bluetooth device B, the intelligent system may flag the state of the data that has been transmitted, that is, flag it as the transmitted state. For example, the identification of data that has been transmitted may be set to 1, and conversely, the identification of data that has not been transmitted may be set to 0 by default. After marking the state of the data which has been transmitted, the intelligent system can detect the data received by itself, thereby being able to acquire the data which has been transmitted and display the data which has been transmitted. For example, if the intelligent system detects that the data received by the intelligent system includes video data a and video data B, wherein the identifier of the video data a is 1 and the identifier of the video data B is 0, the intelligent system reads the video data a and plays the video data a. The intelligent system detects the state of the data in the self memory in real time and displays the state of the data as the transmitted data, so that the effect of rapidly displaying the transmitted data while carrying out data transmission among Bluetooth devices can be realized.
The method has the beneficial effects that the step of displaying the sent data is added on the basis of the first embodiment. Therefore, the problem that data transmission cannot be carried out among slave devices in the prior art is effectively solved, rapid data transmission among a plurality of Bluetooth devices is realized, and the effect of rapidly displaying the transmitted data is achieved.
