The received electromagnetic wave signals include:

Step 1: Determine the current target channel state to be switched to according to the predetermined sequence of channel states.

The order of the channel states may be preset, for example, the channel states may be sorted according to the order of the working frequency bands of the channel states from low to high or from high to low. The order of the channel states can also be obtained according to the communication quality of the electromagnetic wave signal in each channel state in the last communication process, for example, the letters are sorted according to the communication quality of the electromagnetic wave signal in the last communication process from high to low. In an example, the channel state sequence may also be calculated by a preset algorithm.

Step 2, switch the antenna corresponding to the target channel state to the target channel state, and use the corresponding antenna to receive electromagnetic wave signals.

Step 3: After the corresponding antenna works for a specified period of time in the currently determined channel state, return to step 1: determine the current target channel state to be switched to according to the predetermined channel state sequence until the currently determined channel state is The last channel state.

Step 1: Analyze the electromagnetic wave signals received in each channel state respectively, and obtain the signal strength of the electromagnetic wave signals received in each channel state and the background noise of the whole machine environment.

The signal strength of the electromagnetic wave signal may be represented by an RSSI value, RSRQ (Reference Signal Receiving Quality, reference signal receiving quality) or RSRP (Reference Signal Receiving Power, reference signal receiving power) of the electromagnetic wave signal. The environmental noise floor of the whole machine is the total noise in the system except for the useful signal; the environmental noise floor of the whole machine is emitted by the interference of the equipment board itself and external interference, and is received by the antenna or a device with an antenna function.

Step 2, among the electromagnetic wave signals whose signal intensity is greater than the preset intensity threshold, determine the electromagnetic wave signal with the smallest environmental noise floor of the whole machine, and obtain the target electromagnetic wave signal.

The preset intensity threshold can be customized according to the actual situation and needs to meet the communication requirements of the device. If the signal strength of the electromagnetic wave signal is greater than the preset strength threshold, it indicates that the electromagnetic wave signal can be used for effective communication.

Through the selection of the channel state, effective Improve the noise floor problem caused by the interference received by the antenna body, and finally reduce the noise floor of the whole machine environment and improve the communication quality.

In a possible implementation manner, the analysis of the received electromagnetic wave signals in each channel state to determine the channel state with the best communication quality includes:

Utilize the tuning device to analyze the first preamble signal received under each channel state, and obtain the RSSI of the first preamble signal of each channel state respectively; select the channel state with the highest RSSI as the channel state with the best communication quality .

The making the antenna of the electronic device work in the channel state with the best communication quality includes:

A tuning device is used to adjust the wireless channel state, so that the antenna works in the channel state with the best communication quality.

In the embodiment of the present application, the tuning device is used to switch the wireless channel state, and the tuning device detects RSSI to select the channel state with the best communication quality, which can further increase the communication speed. Moreover, RSSI measurement is simple, which can reduce the complexity of tuning devices, thereby saving hardware costs.

When the number of channel states is large, for example, when only the preamble sequence cannot be traversed completely, the channel state with the best communication quality can be selected through a preset algorithm. In a possible implementation manner, the above-mentioned antennas of the electronic equipment are made to work in different channel states at different time periods, and the antennas of the above-mentioned electronic equipment are used to receive electromagnetic wave signals in different time periods respectively, so that the antennas receive signals in each channel state. received electromagnetic wave signals, including:

Step a, according to the analysis results of each electromagnetic wave signal in the historical data, determine the current channel state to be switched to through a preset algorithm.

Step b, switching the antenna of the above-mentioned electronic device to work for a specified time in the currently determined channel state to obtain the currently received electromagnetic wave signal.

The above analyzes the electromagnetic wave signals received in each channel state to determine the channel state with the best communication quality, including:

Step c, judging whether the RSSI of the currently received electromagnetic wave signal satisfies the preset quality condition, if so, then determine the channel state corresponding to the currently received electromagnetic wave signal as the channel state with the best communication quality; The analysis result of the electromagnetic wave signal is used as historical data, and returns to step a: according to the analysis result of each electromagnetic wave signal in the historical data, determine the current channel state to be switched to through a preset algorithm.

The preset algorithm can be customized according to the actual situation. For example, the preset algorithm can be a difference algorithm or a median algorithm. Taking the median algorithm as an example, assuming that there are N channel states, they are called the 1st to the Nth channel states in ascending or descending order of the working frequency bands corresponding to the channel states. In the process of one connection, first obtain the RSSI of the electromagnetic wave signal of the first channel state, the [N/2]th channel state, and the Nth channel state respectively, where [] represents the rounding symbol, which can be rounded up round up or down. Compare the RSSI of the first channel state with the RSSI of the Nth channel state, and halve the interval of the channel state. For example, if the RSSI of the first channel state is greater than the RSSI of the Nth channel state, set The interval of the channel state is halved, the new interval is from the first channel state to the [N/2]th channel state, the median value is the [N/4]th channel state, and the antenna is adjusted to work at the [N/4th] ] channel state, so as to obtain the RSSI of the [N/4]th channel state; compare the RSSI of the first channel state with the RSSI of the [N/2]th channel state, and then halve the interval again until the calculated The RSSI of the last channel state or the currently calculated channel state is greater than the preset RSSI threshold, and the channel state with the best communication quality is obtained.
