The electronic equipment comprises one or more antennas, and at least one antenna in the electronic equipment can work in different channel states; the specific implementation manner of the antenna operating in different channel states may be referred to in the related art, and may be implemented by an antenna process, impedance matching, and the like. The number of antennas included in the electronic device and the number of channel states that each antenna can support can be set by users according to actual situations. The antenna is corresponding to a working frequency band under each channel state, one channel state corresponds to one working frequency band, and the working frequency bands of the channel states can be different. In one example, the wireless communication method according to the embodiment of the present application may be performed each time a packet of data is transmitted/received.

In one example, different channel states of the antenna can be realized by physical multiple channels of the antenna, and in other examples, the channel states can be switched by adjustable devices such as switches, capacitors, diodes and the like. The channel can be realized from a frequency dimension and a time dimension, specifically, a plurality of discrete channels (each discrete channel corresponds to one channel state) can be realized by frequency division and time division, the division of an infinite number of discrete channels can be realized theoretically, and in the actual use process, the number of discrete channels, namely the channel states, is determined according to the actual situation. In an actual operation environment, the strength of the electromagnetic wave signal in each channel state is different, and the channel state with the best communication quality can be selected by the wireless communication method of the embodiment of the application.

S102, analyzing the electromagnetic wave signals received in each channel state, and determining the channel state with the best communication quality.

The electromagnetic wave signals of each channel state are analyzed, and the channel state with the best communication quality is determined to obtain the channel state (hereinafter referred to as a target channel state). The communication quality in the present application preferably means that a specified communication quality index is preferable, for example, the Signal-to-Noise Ratio (snr) is the largest, the RS-CINR (Carrier to Interference plus Noise Ratio) is the largest, or the RSSI (Received Signal Strength) is the strongest; further, the communication quality and the like may be obtained by performing weighted average in combination with a plurality of communication quality indicators.

And S103, switching the antenna of the electronic equipment to the channel state with the best communication quality, and performing data transceiving by using the antenna of the electronic equipment working in the channel state with the best communication quality.

The antenna of the electronic device is enabled to work in the channel state with the best communication quality through a software and/or hardware mode, so that the electronic device can transmit and receive data through the antenna working in the channel state with the best communication quality, and wireless communication quality, such as communication distance and communication stability of the device, is improved.

In the embodiment of the application, the antenna of the electronic device can work in different channel states, the working frequency bands of the antenna in different channel states are different, and the antenna is adjusted to the channel state with the best communication quality to work, so that the antenna of the electronic device in the channel state with the best communication quality can receive and transmit data, the wireless communication requirements of different environments can be met, the wireless communication quality is obviously improved, and the environmental adaptability of a wireless product is obviously improved.

In a possible implementation manner, the acquiring each electromagnetic wave signal received by an antenna of the electronic device in different channel states includes: the antenna of the electronic equipment is enabled to work in different channel states at different time intervals, and the antenna of the electronic equipment is utilized to receive electromagnetic wave signals at different time intervals respectively, so that the electromagnetic wave signals received by the antenna in each channel state are obtained.

The antenna can work in different channel states at different time intervals in a time division multiplexing mode, and therefore electromagnetic wave signals received by the antenna in each channel state can be acquired.

When the number of the channel states is small, the channel state with the best communication quality can be selected in a traversal mode. In a possible implementation manner, the operating the antenna of the electronic device in different channel states at different time intervals, and receiving the electromagnetic wave signals in different time intervals by using the antenna of the electronic device respectively to obtain the electromagnetic wave signals received by the antenna in each channel state includes:

step one, determining a target channel state to be switched to currently according to a predetermined channel state sequence.

The order of the channel states may be predetermined, for example, the channel states may be sorted according to the order of the operating frequency bands of the channel states from low to high or from high to low. The channel state sequence may also be obtained according to the communication quality of the electromagnetic wave signal in each channel state during the last communication, for example, according to the letter ordering from high to low of the communication quality of the electromagnetic wave signal during the last communication. In one example, the channel state sequence may also be calculated by a preset algorithm.

And step two, switching the antenna corresponding to the target channel state, and receiving the electromagnetic wave signal by using the corresponding antenna.

Step three, after the corresponding antenna works for a specified time length in the currently determined channel state, returning to execute the step one: and determining the current target channel state to be switched to according to the predetermined channel state sequence until the current determined channel state is the last channel state.

The specified duration can be duration of a period, the specified duration can be set according to actual conditions in a user-defined mode, the number of channel states in the embodiment of the application is small, and the specified duration can be: the product of the specified duration and the number of channel states is less than the duration of a preamble sequence of a packet data.

For example, if the number of channel states that can be supported by all antennas in the electronic device is n and the duration of the preamble sequence of one packet data is S, the specified duration should be less than S/n.

The preamble signal is a series of signals transmitted before the transmission of the real communication data, and may be understood as a probe signal or a notification signal before the transmission of the real communication data, and the peer wireless device transmits a preamble signal (hereinafter referred to as a first preamble signal) and receives the first preamble signal in each channel state by using an antenna in the electronic device. And further analyzing the first preamble sequence signal of each channel state to determine the channel state with the best communication quality.

In the embodiment of the application, the product of the specified duration and the channel state quantity is less than the duration of the preamble sequence of one packet of data, so that the channel state with the best communication quality can be determined before the real communication data is sent, the sending of the real communication data is not influenced, an extra detection signal is not needed to be sent, and the communication efficiency can be improved.

and step A, analyzing the electromagnetic wave signals received in each channel state respectively to obtain the received signal strength RSSI of the electromagnetic wave signals received in each channel state.

And B, selecting the channel state of the electromagnetic wave signal with the maximum RSSI as the channel state with the best communication quality.

In one example, the RSSI of the electromagnetic wave signal received in each channel state can be determined by using the wireless transceiver module in the electronic device, and the wireless transceiver module itself has the function of calculating the RSSI of the electromagnetic wave signal, and can directly multiplex the function. Generally, the wireless transceiver module can only receive the electromagnetic signals collected in one channel state at the same time, for example, as shown in fig. 3, the electromagnetic signals received in each channel state are sequentially sent to the wireless transceiver module, so that the wireless transceiver module is used to obtain the communication quality of each channel state. The sequence of receiving electromagnetic wave signals by the wireless transceiver module in each channel state can be set by user according to actual conditions, and the sequence is within the protection range of the application. In the embodiment of the application, the wireless transceiver module is used for analyzing the electromagnetic wave signals received in each channel state, no additional communication quality detection circuit is needed, and the cost can be saved.

step one, respectively analyzing the electromagnetic wave signals received in each channel state to obtain the signal intensity of the electromagnetic wave signals received in each channel state and the environment background noise of the whole machine.

The Signal strength of the electromagnetic wave Signal may be represented by an RSSI value, an RSRQ (Reference Signal Receiving Quality), or an RSRP (Reference Signal Receiving Power) of the electromagnetic wave Signal. The whole machine environment background noise is the total noise except useful signals in the system; the whole environment noise is generated by the interference of the equipment board and the external interference, and is received by the antenna or the device with the antenna function.

And step two, determining the electromagnetic wave signal with the minimum background noise of the whole machine environment in the electromagnetic wave signals with the signal intensity larger than the preset intensity threshold value to obtain the target electromagnetic wave signal.

The preset intensity threshold value can be set by self according to actual conditions and needs to meet the communication requirements of the equipment. When the signal intensity of the electromagnetic wave signal is greater than the preset intensity threshold value, the electromagnetic wave signal is used for performing effective communication.

And step three, taking the channel state corresponding to the target electromagnetic wave signal as the channel state with the best communication quality.

In the embodiment of the application, the electromagnetic wave signal with the minimum background noise of the whole environment is determined in the electromagnetic wave signals with the signal intensity larger than the preset intensity threshold value, so that the channel state with the best communication quality is obtained, the problem of background noise rise caused by interference received by the antenna body can be effectively solved through selection of the channel state, the background noise of the whole environment is finally reduced, and the communication quality is improved.

analyzing the received first preamble sequence signals in each channel state by using a tuning device to respectively obtain the RSSI of the first preamble sequence signals in each channel state; and selecting the channel state with the highest RSSI as the channel state with the best communication quality.

The enabling the antenna of the electronic device to work in the channel state with the best communication quality comprises the following steps:

and adjusting the channel state of the wireless by using a tuning device so as to enable the antenna to work in the channel state with the best communication quality.

In the embodiment of the application, the tuning device is used for switching the wireless channel state, and the tuning device detects the RSSI to select the channel state with the best communication quality, so that the communication speed can be further increased. And the RSSI measurement is simple, the complexity of a tuning device can be reduced, and the hardware cost is saved.

When the number of channel states is large, for example, the channel state with the best communication quality can not be completely traversed only by the preamble sequence, the channel state with the best communication quality can be selected by a preset algorithm. In a possible implementation manner, the operating the antenna of the electronic device in different channel states at different time intervals, and receiving the electromagnetic wave signals in different time intervals by using the antenna of the electronic device to obtain the electromagnetic wave signals received by the antenna in each channel state includes:

step a, determining the current channel state to be switched to through a preset algorithm according to the analysis result of each electromagnetic wave signal in the historical data.

And b, switching the antenna of the electronic equipment to a currently determined channel state for a specified working time length to obtain a currently received electromagnetic wave signal.

step c, judging whether the RSSI of the currently received electromagnetic wave signal meets a preset quality condition, if so, determining the channel state corresponding to the currently received electromagnetic wave signal as the channel state with the best communication quality; if not, taking the analysis result of the currently received electromagnetic wave signal as historical data, and returning to execute the step a: and determining the current channel state to be switched to by a preset algorithm according to the analysis result of each electromagnetic wave signal in the historical data.

The preset algorithm can be set in a self-defined mode according to actual conditions, for example, the preset algorithm can be a difference algorithm or a median algorithm and the like. Taking the median algorithm as an example, assume that there are N channel states, which are respectively referred to as the 1 st to nth channel states according to the ascending or descending order of the working frequency bands corresponding to the channel states. In the process of one connection, the RSSI of the electromagnetic wave signals in the 1 st channel state, the [ N/2] th channel state and the nth channel state is respectively obtained, wherein [ ] represents a rounding symbol which can be rounded up or rounded down. Comparing the RSSI of the 1 st channel state with the RSSI of the Nth channel state, halving the interval of the channel states, for example, when the RSSI of the 1 st channel state is greater than the RSSI of the Nth channel state, halving the interval of the channel states, wherein the new interval is from the 1 st channel state to the [ N/2] th channel state, taking the median value as the [ N/4] th channel state, and adjusting the antenna to work in the [ N/4] th channel state, thereby obtaining the RSSI of the [ N/4] th channel state; and comparing the RSSI of the 1 st channel state with the RSSI of the [ N/2] th channel state, and halving the interval again until the RSSI of the last channel state or the currently calculated channel state is calculated to be greater than a preset RSSI threshold value, so as to obtain the channel state with the best communication quality.

The wireless communication method is suitable for wireless devices of different standards, such as Sub-1G, Lora, NB, WIFI, zigbee and the like, especially in narrow-band Internet of things devices, due to environmental differences (such as differences of installation environments, complex multipath effects, material monomers and assembly consistency), the wireless communication quality is poor, after receiving end devices are identified, a self-adaptive optimization screening algorithm is adopted, the realization and fixation of an optimal channel are realized and need to be realized by a tuning assembly, the tuning assembly is generalized, can be a physical multichannel of an antenna, and can also be realized by tuning devices such as switches, capacitors, diodes and the like to realize the switching of the states of antenna channels, so that the screening of the states of the optimal channels is realized. The channel state of the antenna can be realized from a frequency dimension and a time dimension, and particularly, a limited or unlimited discrete channel can be realized through a frequency division system and a time division system, so that the actual notification quality of the wireless device, such as the communication distance and the communication stability of the wireless device, is improved.

The wireless communication method is suitable for equipment transmitting by electromagnetic waves, the equipment is provided with a receiving and transmitting mode, under the conditions of environment difference, position, material change and the like, the quality of wireless communication is detected or identified by a receiving intelligent system, particularly the design and algorithm of a receiving front-end link are adopted, the multi-state work or detection of a receiving channel is realized, and the equipment can timely adjust the working frequency band of the antenna according to the signal intensity change caused by the environment in the communication process through the antenna reconfigurable design and the software logic algorithm, so that the optimal communication is realized.
