[0024] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0025] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0026] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present application described here. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0027] As introduced in the background technology, in the prior art, with the development of Internet of Things technology, smart homes have been popularized in all aspects of life, and various wifi devices and Bluetooth devices have also appeared on the market. Wifi plus Bluetooth devices have also been valued by more and more manufacturers, but there are currently problems that Bluetooth data and wifi data cannot be transmitted at the same time, and interference will be generated when optimizing multiple antennas. That is, when a device has Bluetooth and wifi functions, there will be a problem of receiving or sending Bluetooth data and wifi data at the same time. Most devices only use one antenna to receive and send Bluetooth data or wifi data. This means that when two types of data are sent and received at the same time, the device side can only process one type of data first and then process the other data. If one type of data is too much, it will occupy the processing time of the other type of data, and the user side may experience a situation where data reception is slow.

[0028] In order to solve the problem that it is impossible to realize simultaneous transmission of Bluetooth data and Wi-Fi data of a user terminal in the prior art, the embodiments of the present application provide a data transmission method, a smart device, a data transmission system and a computer-readable storage medium.

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0030] The method embodiments provided in the embodiments of the present application can be executed in a mobile terminal, a computer terminal or a similar computing device. Taking running on a mobile terminal as an example, Figure 1 1 is a hardware structure block diagram of a mobile terminal of a Z method according to an embodiment of the present invention. Figure 1 As shown, the mobile terminal may include one or more ( Figure 1 Only one is shown in the figure) a processor 102 (the processor 102 may include but is not limited to a processing device such as a microprocessor MCU or a programmable logic device FPGA) and a memory 104 for storing data, wherein the mobile terminal may also include a transmission device 106 and an input / output device 108 for communication functions. It can be understood by those skilled in the art that Figure 1 The structure shown is only for illustration and does not limit the structure of the mobile terminal. Figure 1 More or fewer components as shown, or with Figure 1 Different configurations are shown.

[0031] The memory 104 can be used to store computer programs, for example, software programs and modules of application software, such as the computer program corresponding to the Z method in the embodiment of the present invention. The processor 102 executes various functional applications and data processing by running the computer program stored in the memory 104, that is, the above method is implemented. The memory 104 may include a high-speed random access memory, and may also include a non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some examples, the memory 104 may further include a memory remotely arranged relative to the processor 102, and these remote memories may be connected to the mobile terminal via a network. Examples of the above-mentioned network include but are not limited to the Internet, an intranet, a local area network, a mobile communication network, and a combination thereof. The transmission device 106 is used to receive or send data via a network. The above-mentioned specific examples of the network may include a wireless network provided by a communication provider of the mobile terminal. In one example, the transmission device 106 includes a network adapter (Network Interface Controller, referred to as NIC), which can be connected to other network devices through a base station so as to communicate with the Internet. In one example, the transmission device 106 may be a radio frequency (RF) module, which is used to communicate with the Internet wirelessly.

[0032] In this embodiment, a data transmission method running on a mobile terminal, a computer terminal or a similar computing device is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0033] Figure 2 is a flow chart of a data transmission method according to an embodiment of the present application. Figure 2 As shown, the method comprises the following steps:

[0034] Step S201, acquiring transmission data sent by a user terminal, the transmission data including Bluetooth data and Wi-Fi data;

[0035] Specifically, the Bluetooth data and Wi-Fi data sent by the user terminal are fully acquired to obtain the interference situation of each channel, providing a data basis for subsequent processing and analysis.

[0036] Step S202, determining multiple groups of data transmission channels, and using an adaptive algorithm to determine the total signal interference amount of each group of the data transmission channels, the total signal interference amount includes the interference metric of the Bluetooth signal, the interference metric of the Wi-Fi signal, and the cross-interference metric between the Bluetooth signal and the Wi-Fi signal, and a group of the data transmission channels includes a Bluetooth transmission channel and a Wi-Fi transmission channel;

[0037] Specifically, MIMO technology uses multiple transmitting antennas and receiving antennas to enhance data transmission rate and signal quality, and utilizes multipath propagation, that is, the signal will be reflected multiple times before reaching the receiver to form multiple paths, to improve the performance and efficiency of the communication system. The use of MIMO technology effectively solves the problem that one antenna can only process one type of data when Bluetooth data and WiFi data are processed simultaneously.

[0038] Furthermore, when a signal enters the transmitter, it will be divided into multiple paths for processing. During the transmission process, the signal will be reflected, refracted, scattered, etc. by various objects in the environment, and eventually the signal will reach the receiving end along different paths. MIMO technology uses multiple antennas to receive these signals, thereby enhancing channel capacity and data transmission efficiency.

[0039] The method of using an adaptive algorithm to determine the total signal interference of each group of the data transmission channels includes the following steps:

[0040] Step S301, obtaining the signal strength and channel of each of the above-mentioned Bluetooth transmission channels, and determining the Bluetooth interference metric of the reserve Bluetooth channel according to the signal strength and channel of all the above-mentioned Bluetooth transmission channels, wherein the above-mentioned reserve Bluetooth channel is a Bluetooth transmission channel in the reserve transmission channel, and the above-mentioned reserve transmission channel is one of the multiple groups of the above-mentioned data transmission channels;

[0041] Wherein, determining the Bluetooth interference metric of the reserve Bluetooth channel according to the signal strength and channel of all the above Bluetooth transmission channels includes the following steps:

[0042] Step S3011, according to the Bluetooth interference formula Determine the Bluetooth interference measure of the above-mentioned preliminary Bluetooth channel, where I(Bluetooth) is the Bluetooth interference measure of the above-mentioned preliminary Bluetooth channel, Q(j) is the signal strength of the Bluetooth device corresponding to the j-th above-mentioned Bluetooth transmission channel, d is the channel of the above-mentioned preliminary Bluetooth channel, d(j) is the channel of the j-th above-mentioned Bluetooth transmission channel, |dd(j)| is the frequency distance between the above-mentioned preliminary Bluetooth channel and the j-th above-mentioned Bluetooth transmission channel, and j≥1.

[0043] Specifically, adding 1 to the Bluetooth interference formula is to avoid the situation where the denominator is zero and the fraction is invalid. In the process of implementing multi-antenna data interaction with MIMO technology, signal interference between multiple antennas is inevitable. Adding an adaptive algorithm to the program to determine the Bluetooth interference metric for the reserve Bluetooth channel can effectively reduce mutual interference between antennas and improve communication quality.

[0044] The interference metric reflects the degree to which the channel is interfered by surrounding signals.

[0045] Step S302, obtaining the signal strength and channel of each of the above-mentioned wifi transmission channels, and determining the wifi interference metric of the reserve wifi channel according to the signal strength and channel of all the above-mentioned wifi transmission channels, wherein the above-mentioned reserve wifi channel is a wifi transmission channel in the above-mentioned reserve transmission channels;

[0046] Wherein, according to the signal strength and channel of all the above-mentioned WiFi transmission channels, determining the WiFi interference metric of the reserve WiFi channel includes the following steps:

[0047] Step S3021, according to the wifi interference formula Determine the WiFi interference metric of the above-mentioned reserve WiFi channel, where I(WiFi) is the WiFi interference metric of the above-mentioned reserve WiFi channel, P(i) is the signal strength of the WiFi access point corresponding to the i-th WiFi transmission channel, c is the channel of the above-mentioned reserve WiFi channel, c(i) is the channel of the i-th WiFi transmission channel, |cc(i)| is the frequency distance between the above-mentioned reserve WiFi channel and the i-th WiFi transmission channel, and i≥1.

[0048] Specifically, adding 1 to the wifi interference formula is to avoid the situation where the denominator is zero and the fraction is invalid. In the process of realizing multi-antenna data interaction with MIMO technology, signal interference between multiple antennas is inevitable. Adding an adaptive algorithm to the program to determine the wifi interference metric of the reserve wifi channel can effectively reduce mutual interference between antennas and improve communication quality.

[0049] Step S303, determining a cross interference measure between the standby Bluetooth channel and the standby WiFi channel according to the frequency channel of the standby Bluetooth channel and the frequency channel of the standby WiFi channel;

[0050] Wherein, determining the cross interference measure between the above-mentioned preliminary Bluetooth channel and the above-mentioned preliminary WiFi channel according to the channel of the above-mentioned preliminary Bluetooth channel and the channel of the above-mentioned preliminary WiFi channel comprises the following steps:

[0051] Step S3031, according to the cross interference formula Determine the cross interference measure between the above-mentioned reserve Bluetooth channel and the above-mentioned reserve WiFi channel, where I (Cross) is the cross interference measure between the channel of the above-mentioned reserve Bluetooth channel and the above-mentioned reserve WiFi channel, alpha is a trade-off parameter, c is the channel of the above-mentioned reserve Bluetooth channel, d is the channel of the above-mentioned reserve WiFi channel, and |cd| is the frequency distance between the above-mentioned reserve Bluetooth channel and the above-mentioned reserve WiFi channel.

[0052] Specifically, adding 1 to the cross-interference formula is to avoid the situation where the denominator is zero and the fraction is invalid, and alpha is used to adjust the weight of the cross-interference. In the process of realizing multi-antenna data interaction with MIMO technology, signal interference between multiple antennas is inevitable. Adding an adaptive algorithm to the program to determine the cross-interference measure between the reserve Bluetooth channel and the reserve WiFi channel can effectively reduce the mutual interference between antennas and improve the communication quality.

[0053] Step S304: determining the total signal interference amount of the above-mentioned preliminary transmission channel according to the above-mentioned Bluetooth interference metric, the above-mentioned WiFi interference metric and the above-mentioned cross-interference metric.

[0054] Specifically, the total signal interference calculation formula of the prepared transmission channel is (c(WiFi), d(Bluetooth)) = argmin(I(WiFi) + I(Bluetooth) + I(Cross)), where c(WiFi) is the WiFi channel and d(Bluetooth) is the Bluetooth channel. According to the total interference, the optimal Wi-Fi and Bluetooth channels can be dynamically selected in the actual environment to reduce interference and improve communication quality.

[0055] Step S203, determining a target transmission channel at least according to the total signal interference of each group of the data transmission channels, and using the target transmission channel to receive the transmission data, the target transmission channel being one group of the multiple groups of data transmission channels.

[0056] Specifically, when WiFi data and Bluetooth data need to be transmitted at the same time, the algorithm calculates the channel suitable for WiFi data transmission and the channel suitable for Bluetooth data transmission based on the interference of the current surrounding channels. The two channels need to meet the condition of minimum mutual influence at the same time, that is, they cannot be on the same channel or channels with similar frequencies. By counting the number of data packets sent and received per unit time, the channel utilization is estimated, and the congestion found in the surrounding area is calculated.

[0057] Furthermore, in unit time, we count the number of data packets sent by the WiFi access point AP(i) on channel c(i) as Tx(i), and the number of data packets received as Rx(i). We can calculate the data transmission volume on the current channel, and then process it with the interference measure calculated above to obtain the channel utilization rate between channels, and then select the channel with less channel congestion to transmit data.

[0058] The target transmission channel is determined at least according to the total signal interference of each group of the data transmission channels, including two optional schemes:

[0059] In an optional solution, a group of the above-mentioned data transmission channels with the smallest total signal interference is determined as the target transmission channel;

[0060] In another optional scheme, the number of sent data packets and the number of received data packets of each channel are determined, and the above-mentioned channel is a Bluetooth transmission channel or a WiFi transmission channel; the data transmission volume of the above-mentioned channel is determined according to the above-mentioned number of sent data packets and the above-mentioned number of received data packets of the above-mentioned channel; the channel utilization rate of the above-mentioned channel is determined according to the above-mentioned data transmission volume of the above-mentioned channel and the above-mentioned total signal interference; the above-mentioned data transmission channel composed of the above-mentioned Bluetooth transmission channel and the above-mentioned WiFi transmission channel with the highest channel utilization rate is determined as the above-mentioned target transmission channel.

[0061] Specifically, because Wi-Fi data is usually transmitted on the 2.4GHz and 5GHz frequency bands, and Bluetooth data is mainly transmitted on the 2.4GHz frequency band, the adaptive algorithm also needs to determine the frequency bands supported by the surrounding environment. If the surrounding environment supports data exchange between the 2.4GHz and 5GHz frequency bands, the Wi-Fi data is fixed to be transmitted on the 5GHz frequency band, and the Bluetooth data is fixed to be transmitted on the 2.4GHz frequency band.

[0062] Furthermore, the spectrum between multiple channels will partially overlap, which will cause interference between signals. The frequency interval between channels is only 5MHz. In the 2.4GHz band, a 20MHz channel bandwidth is generally used. There are 13 channels in this band, and 14 in some areas. The only channels that do not overlap at all are channels 1, 6, and 11, while other channels overlap. Communicating in channels with less overlap can effectively improve signal quality.

[0063] In some instances, such as Figure 3 As shown, the above method also includes the following steps:

[0064] Step S401, determining the transmitting and receiving antennas of the plurality of smart devices based on MIMO technology;

[0065] Step S402, splitting the transmission data into a plurality of transmission sub-data;

[0066] Step S403: using the plurality of the above-mentioned transceiver antennas to respectively receive the above-mentioned transmission sub-data.

[0067] Specifically, when a signal enters the transmitter, it will be divided into multiple paths for processing. During the transmission process, the signal will be reflected, refracted, scattered, etc. by various objects in the environment, and eventually the signal will reach the receiving end along different paths. MIMO technology uses multiple antennas to receive these signals, thereby enhancing channel capacity and data transmission efficiency.

[0068] The above-mentioned data transmission method of the present application first obtains the transmission data sent by the user terminal, and the transmission data includes Bluetooth data and WiFi data; then determines multiple groups of data transmission channels, and uses an adaptive algorithm to determine the total signal interference of each group of data transmission channels, the total signal interference includes the interference measurement of Bluetooth signals, the interference measurement of WiFi signals, and the cross-interference measurement between Bluetooth signals and WiFi signals, and a group of data transmission channels includes a Bluetooth transmission channel and a WiFi transmission channel; finally, at least according to the total signal interference of each group of data transmission channels, the target transmission channel is determined, and the transmission data is received by using the target transmission channel, and the target transmission channel is one of the multiple groups of data transmission channels. The method uses MIMO technology to solve the problem that Bluetooth data and WiFi data cannot be transmitted at the same time. At the same time, according to the adaptive algorithm, a relatively clean channel is selected to transmit Bluetooth data, and the interference caused by the simultaneous transmission of Bluetooth data and WiFi data in the case of multiple antennas is optimized, which can effectively improve the data transmission efficiency of the device, improve the performance of the communication system, and enhance the user experience.

[0069] In order to enable those skilled in the art to more clearly understand the technical solution of the present application, the implementation process of the data transmission method of the present application will be described in detail below in conjunction with specific embodiments.

[0070] This embodiment relates to a specific data transmission method, such as Figure 4 As shown, the following steps are included:

[0071] Step S1, using MIMO technology to implement multi-antenna data transmission technology to solve the problem of simultaneous transmission of Bluetooth data and WiFi data;

[0072] Step S2, using an adaptive algorithm based on MIMO technology to optimize the problem of data transmission interference between antennas when multiple antennas are used;

[0073] Step S3, Wifi and Bluetooth transmission channels are different, and Wifi data can be mainly transmitted on the 5GHz channel.

[0074] It should be noted that the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and that, although a logical order is shown in the flowcharts, in some cases, the steps shown or described can be executed in an order different from that shown here.
