FIG. 2 is a schematic structural diagram of a device for dynamically adjusting transmit power according to an embodiment of the present invention. detailed description

The embodiment of the present invention is based on whether the received power value of the peer wireless signal is within a preset threshold range, thereby determining whether the received wireless signal is located within a power value range capable of ensuring communication quality; In the preset threshold range, the wireless signal transmission power is not adjusted; if it is not within the preset threshold range, the current wireless signal transmission power needs to be adjusted; when the preset threshold is higher than the preset threshold range In a limited time, the transmit power of the wireless signal is reduced, and when the lower limit of the preset threshold range is lower, the transmit power of the wireless signal is increased.

The technical solution of the embodiment of the present invention, when the received power of the received wireless signal is lower than the lower limit of the set threshold range, the communication quality of the wireless signal is affected; since the wireless signal transmission and reception of the Bluetooth device is equivalent, At this time, the peer device transmitting the wireless signal may also receive a wireless signal, which may affect the communication quality. Therefore, in this case, the transmission power needs to be increased to ensure the communication quality at both ends of the Bluetooth device; and the received wireless When the received power of the signal is higher than the upper limit of the set threshold range, although the communication quality of the wireless signal can be ensured, the transmission power of the wireless signal can be lowered due to the waste of the transmission power of the wireless signal being too high.

Specific embodiments of the technical solution of the present invention are further described in detail below.

FIG. 1 is a flowchart of a method for dynamically adjusting transmit power according to an embodiment of the present invention. As shown in FIG. 1 , a method for dynamically adjusting transmit power according to an embodiment of the present invention includes the following steps:

Step 101: Acquire a power value of the wireless signal;

Specifically, the received wireless signal is sampled, and an average power value of the sampled wireless signal is calculated as a power value of the wireless signal.

In this step, the average power value of the sampled wireless signal is used as the power value of the wireless signal to determine whether it is within the threshold range, etc., mainly considering that the wireless signal is susceptible to external transmission. The receiving power of the wireless signal may be greatly affected by the transmission medium. Therefore, the average value of the received power can reduce the influence of the external environment on the power of the wireless signal to avoid misadjustment of the transmission power.

Alternatively, the power value of the received wireless signal is obtained by directly measuring the received power of the wireless signal.

Step 102: Determine whether the power value is in a preset threshold range, and end the current processing flow when the current value is not located in the preset threshold range.

The power value of the received wireless signal obtained in step 101 is determined to determine whether the power value is within a preset threshold. In the present invention, when the received power of the wireless signal is within a preset threshold range, high-quality demodulation of the wireless signal can be realized, and the quality of the wireless communication can be ensured. If the received power of the wireless signal is lower than the lower limit of the threshold range, it is considered that the current wireless signal power is too low, which will affect the communication quality, and the transmission power needs to be increased; if the received power of the wireless signal is greater than the upper limit of the threshold range, It is considered that the current wireless signal power is too high, which will cause a waste of transmission power and reduce the transmission power. Due to the peering of Bluetooth devices, similar problems may exist with the peer Bluetooth devices. Therefore, the present invention can determine the power adjustment status of the local Bluetooth device by receiving the power of the signal.

Step 103: Adjust the transmit power.

In the embodiment of the present invention, there are various ways to adjust the transmission power, which are respectively introduced below. The first transmission power adjustment manner is: when determining that the power value of the received wireless signal is greater than the upper limit value of the preset threshold range, the transmission power is reduced. The transmission power is increased when it is determined that the power value of the received wireless signal is less than a lower limit value of the preset threshold range. This power adjustment mode can simply assume that the transmitting power of the transmitting end and the receiving end of the wireless signal are substantially equal. Once the receiving end determines that the received wireless signal is less than the lower limit of the preset threshold range, it considers its own transmission. The power is also small, and the maximum transmit power is required. Correspondingly, once the receiving end determines that the received wireless signal is greater than the upper limit of the preset threshold range, it considers its own transmit power. Larger, which is a waste of transmission power, needs to be reduced. In the present invention, the specific value of the downward adjustment of the transmission power or the increase of the transmission power is not limited and may be a fixed value.

The second transmission power adjustment method is:

A level identification is set for different transmission powers; the Bluetooth device loads level identification information corresponding to the wireless signal transmission power in the transmitted wireless signal. That is to say, the wireless signal carries the level identifier corresponding to the wireless signal transmission power, and the receiving end can determine the transmission power level of the wireless signal according to the received wireless signal, thereby determining how much the transmission power is.

In this way, when it is determined that the power value is greater than an upper limit value of a preset threshold range, the transmit power is adjusted to a corresponding transmit power of a level identifier of a next level lower than a transmit power corresponding to the level identifier in the received wireless signal. Or reducing the transmit power by a set threshold; when determining that the power value is less than a lower limit of the preset threshold range, adjusting the transmit power to a higher level than the transmit power corresponding to the level identifier in the received wireless signal The level identifies the corresponding transmit power, or increases the transmit power by a set threshold.

Assume that the Bluetooth device supports eight transmission levels, which are grades 1 to 8, respectively, and their corresponding transmit powers are 2.5mW, 5mW, 7.5mW, 10mW, 12.5mW, 15mW, 17.5mW, and 20mW. The preset threshold range is 0.5mW~lmW, which means that for Bluetooth devices, no matter how far apart they are, the power of the received signal is 0.5mW~lmW, which guarantees the communication quality.

Assume that the current received signal has a level of 3, and its corresponding transmit power is 7.5 mW; the received power of the received signal is 0.4 mW, which is lower than 0.5 mW. At this time, it is necessary to increase the transmit power, for example, one level can be increased. The transmit power is adjusted to 10mW; of course, the transmit power can also be increased by a set threshold, such as increasing 2mW, and adjusting the current transmit power to 9.5mW; and if the received power of the received signal is l.lmW, greater than lmW At this time, it is necessary to reduce the transmission power. For example, the transmission power can be reduced to 5 mW. Of course, the transmission power can also be lowered by a set threshold. For example, if the transmission power is increased by 2 mW, the current transmission power is adjusted to 9.5 mW. After adjusting the power, The transmit power of the received signal is still monitored in real time to determine if the transmit power is appropriate and the corresponding transmit power adjustment is made.

The third transmission power adjustment method is:

In the embodiment of the present invention, if it is determined whether the power value of step 102 is located before a preset threshold, the method further includes the following steps:

Determining whether the power level in the received wireless signal is greater than or less than the power level corresponding to the current transmit power, and adjusting the current transmit power to the transmit power corresponding to the power level in the received wireless signal.

Before performing step 102, the embodiment of the present invention needs to determine whether the current transmit power matches the transmit power of the received wireless signal, that is, whether the Bluetooth device of the receiving end and the transmitting end transmits the wireless signal with the same transmit power, if The wireless signals transmitted by different transmission powers need to be adjusted to the same transmission power, and then the transmission power adjustment of the wireless signals is performed.

It is still assumed that the Bluetooth device supports eight transmission levels, which are grades 1 to 8, respectively, and their corresponding transmit powers are 2.5 mW, 5 mW, 7.5 mW, 10 mW, 12.5 mW, 15 mW, 17.5 mW, and 20 mW, respectively. The preset threshold range is 0.5mW~lmW.

Assume that the current received signal has a level of 3, and its corresponding transmit power is 7.5 mW, and the current transmit power is 10 mW, and the corresponding transmit power level is 4; at this time, the setting is adjusted according to the transmit power of the Bluetooth device, such as the current transmission. When the power is less than the received signal transmission power level, the current transmission power can be adjusted to the power value corresponding to the received signal transmission power level, otherwise no adjustment is made; if the adjustment principle is adopted, the receiving end does not have to adjust the current transmission power. That is, the wireless signal is still transmitted at 10 mW; if the transmitting end is also the adjustment principle, it needs to adjust the transmission power to be 10 mW. Alternatively, when the current transmit power is greater than the received signal transmit power level, the current transmit power may be adjusted to the power value corresponding to the received signal transmit power level, otherwise no adjustment is made; if the adjustment principle is adopted, the receiving end needs to adjust the current The transmission power is 7.5mW; If the sender is also the principle of this adjustment, it does not need to adjust the transmit power. After the transmission powers of the receiving end and the transmitting end are adjusted to be equal, the power adjustment may be performed according to the foregoing manner of the present invention.

Assume that the current received signal has a level of 3, and its corresponding transmit power is 7.5 mW; the received power of the received signal is 0.4 mW, which is lower than 0.5 mW. At this time, it is necessary to increase the transmit power, for example, one level can be increased. The transmit power is adjusted to 10mW; of course, the transmit power can also be increased by a set threshold, such as increasing 2mW, and adjusting the current transmit power to 9.5mW; and if the received power of the received signal is l.lmW, greater than lmW At this time, it is necessary to reduce the transmission power. For example, the transmission power can be reduced to 5 mW. Of course, the transmission power can also be lowered by a set threshold. For example, if the transmission power is increased by 2 mW, the current transmission power is adjusted to 9.5 mW. After adjusting the power, the transmit power of the received signal is still monitored in real time to determine whether the transmit power is appropriate and the corresponding transmit power adjustment is made.
