With the market of live video and short video growing at a high speed, the application scenes of wireless transmitting device (such as a wireless microphone) products are also becoming more and more. The rapid development of electronic science and technology has made the operation of wireless transmission devices more and more reliable.
However, in the transmission process, the wireless signal emitted by the wireless transmitting device is reflected by an object, so that indexes such as the propagation direction, amplitude, phase and the like of the wireless signal are changed, and the wireless signal is finally superimposed with a signal which is propagated in a straight line to generate multipath interference, and the multipath interference is instantaneous interference. In addition to multipath interference, there are often other external interferences. Most wireless transmitting devices only transmit audio carrier signals with the same frequency to a wireless receiving device, when a certain wireless transmitting device receives interference, the receiving frequency of the receiving device can be changed only by hand, and because the wireless transmitting device only transmits the audio carrier signals with one frequency, communication interruption is inevitable when the frequency is changed, and the use experience and communication perception of a user are reduced.

Detailed Description
At present, most wireless transmitting devices only send a communication signal (such as an audio carrier signal) with the same frequency to an invalid receiving device, and when interference occurs in a certain wireless transmitting device, the receiving frequency of the wireless receiving device can only be manually changed manually, and at the moment, the communication interruption is inevitably caused by changing the frequency, so that the use experience and perception of a user are reduced. Therefore, when the existing wireless transmitting device and the existing invalid receiving device perform invalid communication, the transmitting end easily receives external interference, and the receiving frequency needs to be adjusted manually, so that the communication interruption may occur, and further the communication experience of a user is influenced.
In order to solve the above-mentioned defects, an embodiment of the present application provides a wireless communication method based on a dual-channel technology, in which a wireless transmitting end firstly collects a target communication signal to be transmitted, then sends the target communication signal to a wireless receiving end through a first communication channel and a second communication channel according to different communication frequencies, and then receives a response signal sent by the wireless receiving end, so that wireless communication based on the dual-channel technology between the wireless transmitting end and the wireless receiving end can be achieved. Therefore, the wireless transmitting end transmits the same target communication limited number with different communication frequencies through two channels (namely the first communication information and the second communication channel), and the transmission channel can be rapidly switched even when the communication quality is reduced, so that the uninterrupted wireless communication is ensured, the continuity of communication signal transmission is ensured, and the communication experience of a user is improved.
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
First embodiment
Referring to fig. 1, a flow chart of a wireless communication method based on a dual channel technology provided in this embodiment is schematically illustrated, where the method includes the following steps:
s101: the wireless transmitting terminal collects a target communication signal to be transmitted.
In this embodiment, any communication signal transmitted by the wireless transmitting terminal in this embodiment is defined as a target communication signal, and in order to improve the stability and continuity of the wireless communication process, the structure of the wireless transmitting terminal includes not only a signal acquisition module (such as a wireless microphone) for acquiring a signal and a processor for processing signal data, but also includes two wireless communication modules, i.e., a first wireless communication module and a second wireless communication module in the left diagram of fig. 2, as shown in the left diagram of fig. 2. Similarly, in order to improve the stability and continuity of the wireless communication process, the wireless receiving end includes not only a signal output module for outputting a communication signal (e.g., an audio signal) and a processor for processing signal data, but also two wireless communication modules, i.e., a first wireless communication module and a second wireless communication module in the right side of fig. 2, as shown in the right side diagram of fig. 2.
The first wireless communication module and the second wireless communication module in the wireless transmitting end and the wireless receiving end can output two paths of wireless digital signals with different frequencies respectively.
In this way, after the wireless transmitting end acquires the target communication signal to be transmitted by using the signal acquisition module (such as a wireless microphone, etc.), the subsequent step S102 may be continuously executed.
S102: and the wireless transmitting terminal simultaneously and respectively transmits the target communication signal to the wireless receiving terminal through the first communication channel and the second communication channel according to different communication frequencies.
It should be noted that, in order to implement the dual-channel communication between the wireless transmitting end and the wireless receiving end, an optional implementation manner is that the wireless transmitting end may previously establish a first communication channel with a first wireless communication module of the wireless receiving end through a first wireless communication module, and the wireless transmitting end may also previously establish a second communication channel with a second wireless communication module of the wireless receiving end through a second wireless communication module.
On this basis, after acquiring the target communication signal to be transmitted through step S101, the wireless transmitting end may transmit the target communication signal to the wireless receiving end through the first communication channel and the second communication channel, respectively, according to different communication frequencies.
Specifically, as shown in fig. 3, the wireless transmitting end may pack the target communication signal into a data packet, and transmit the data packet to its first wireless communication module and second wireless communication module, where the two wireless communication modules may transmit the data packet to two wireless communication modules corresponding to the wireless receiving end at the first time; after the two communication modules successfully send the data packets in unit time (such as 1 second, the specific value is not limited), the next group of data packets can be sent immediately so as to repeat the sending action,
it can be understood that, in the sending process, the first wireless communication module and the second wireless communication module of the wireless receiver receive the data packets successively, and since the two paths of data packets are the same, which path is received first is checked first (i.e., validity of the data packets is verified, and errors caused by interference in the transmission process are prevented) and which path of data packets is stored.
S103: the wireless transmitting end receives the response signal sent by the wireless receiving end, and wireless communication between the wireless transmitting end and the wireless receiving end based on a dual-channel technology is achieved.
In this embodiment, after the wireless transmitting end sends the target communication signal to the wireless receiving end through the first communication channel and the second communication channel at the same time according to different communication frequencies through step S102, the wireless transmitting end may further receive a response signal (such as "correctly receive command packet") sent by the wireless receiving end, and the response signal is used as a flag indicating that the target communication signal is successfully sent, so that wireless communication based on a dual-channel technology between the wireless transmitting end and the wireless receiving end is achieved.
For example, when the first wireless communication module of the wireless transmitting end sends a data packet to the first wireless communication module of the wireless receiving end, the first wireless communication module of the wireless receiving end may perform validity check after receiving the data packet, and if the check is passed, the first wireless communication module of the wireless receiving end may send a response signal "correctly receive command packet" to the first wireless communication module of the wireless transmitting end.
Or, an optional implementation manner is that, if the wireless transmitting end does not receive, through the first wireless communication module, the response signal (i.e., "correctly receive command packet") sent by the first wireless communication module of the wireless receiving end within a first preset time (a specific value may be set according to an actual situation, which is not limited in this embodiment of the present application, and may be, for example, a value of 1 second, etc.), the target communication signal is sent to the wireless receiving end through the first communication channel again; further, if the wireless transmitting end still does not receive the response signal sent by the first wireless communication module of the wireless receiving end through the first wireless communication module within the second preset time (for example, the value may be n times, for example, 3 times, etc. of the first preset time), it may be determined that the communication quality of the first communication channel is not available, and at this time, the communication frequency of the first communication channel needs to be switched to send the target communication signal to the wireless receiving end again.
And after the wireless transmitting end determines that the communication quality of the first communication channel is unavailable, switches the communication frequency of the first communication channel and sends the target communication signal to the wireless receiving end again, the wireless transmitting end can also send the switched communication frequency of the first communication channel to the wireless receiving end through the second communication channel, so that the wireless receiving end adjusts the communication frequency of the first wireless communication module to the switched communication frequency, and performs communication pairing operation again to receive the target communication signal sent again by the wireless transmitting end.
Another optional implementation manner is that, if the wireless transmitting terminal does not receive, within the first preset time, the response signal (i.e., "correctly receive the command packet") sent by the second wireless communication module of the wireless receiving terminal through the second wireless communication module, the target communication signal is sent to the wireless receiving terminal through the second communication channel again; further, if the wireless transmitting terminal still does not receive the response signal sent by the second wireless communication module of the wireless receiving terminal through the second wireless communication module within the second preset time, it may be determined that the communication quality of the second communication channel is unavailable, and at this time, the communication frequency of the second communication channel needs to be switched to send the target communication signal to the wireless receiving terminal again.
And after the wireless transmitting end determines that the communication quality of the second communication channel is unavailable, switches the communication frequency of the second communication channel and sends the target communication signal to the wireless receiving end again, the wireless transmitting end can also send the switched communication frequency of the second communication channel to the wireless receiving end through the first communication channel, so that the wireless receiving end adjusts the communication frequency of the second wireless communication module to the switched communication frequency, and performs communication pairing operation again to receive the target communication signal sent again by the wireless transmitting end.
In addition, in a possible implementation manner of the embodiment of the present application, the number of times that the first wireless communication module or the second wireless communication module of the wireless transmitting end repeatedly transmits the target communication signal through the first communication channel or the second communication channel, respectively, may also be counted, and the communication quality of the first communication channel or the second communication channel is evaluated according to the counted result, so as to obtain an evaluation result, it may be understood that the higher the counted result (i.e., the more the number of times that the target communication signal is repeatedly transmitted), the worse the communication quality of the corresponding channel is indicated; conversely, the lower the statistical result (i.e., the fewer the number of times of repeatedly transmitting the target communication signal), the better the communication quality of the corresponding channel is, and the phenomenon of packet loss does not occur.
If the evaluation results of the first communication channel and the second communication channel both indicate that the communication quality is very good, in order to save communication resources, the transmission power of one communication channel can be properly reduced, and the wireless signal quality of the channel can be detected, so that the transmission power can be reduced as much as possible under the condition of ensuring that the communication quality is normal, and the communication resource consumption can be reduced.
If the evaluation results of the first communication channel and the second communication channel both indicate that the communication quality is general, even worse, the transmission frequency of one of the communication channels can be changed first, and whether the wireless signal quality of the channel is improved or not can be detected; if not, the transmitting power is increased, and whether the wireless signal quality of the channel is improved or not is detected, in short, at least one communication channel is required to be ensured to be capable of normally communicating without interruption, so that the continuity of wireless communication is ensured, and the communication experience of a user is further improved.
In summary, according to the wireless communication method, the wireless communication device and the wireless communication equipment based on the dual-channel technology provided by the embodiment, the wireless transmitting end firstly collects the target communication signal to be transmitted, then sends the target communication signal to the wireless receiving end through the first communication channel and the second communication channel according to different communication frequencies, and then receives the response signal sent by the wireless receiving end, so that the wireless communication between the wireless transmitting end and the wireless receiving end based on the dual-channel technology can be realized. Therefore, the wireless transmitting end transmits the same target communication limited number with different communication frequencies through two channels (namely the first communication information and the second communication channel), and the transmission channel can be rapidly switched even when the communication quality is reduced, so that the uninterrupted wireless communication is ensured, the continuity of communication signal transmission is ensured, and the communication experience of a user is improved.
