Detailed description of the invention
Basic thought of the present invention is: whether be positioned at default threshold range according to the performance number of the opposite end wireless signal received, within the scope of determining with this whether the wireless signal received is positioned at the performance number that ensure that communication quality；If being positioned at described default threshold range, wireless signal transmission power is not made adjustment；Without being positioned at described default threshold range, then need the transmitting power of current radio signal is adjusted；When higher than the upper limit of predetermined threshold range, reduce the transmitting power of wireless signal, when less than the lower limit of predetermined threshold range, increase the transmitting power of wireless signal.
Technical scheme, main theory is according to being, when when receiving power less than the lower limit setting threshold range of the wireless signal received, it will have influence on the communication quality of wireless signal；It is reciprocity for receiving and dispatching due to the wireless signal of bluetooth equipment, now launch the opposite equip. of this wireless signal receive that wireless signal is likely to can be more weak and affect communication quality, therefore, in this case, the communication quality launching power to ensure bluetooth equipment two ends need to be increased；And when receiving power higher than the higher limit setting threshold range of the wireless signal received, although can ensure that the communication quality of wireless signal, but cause the waste launching power owing to the transmitting power of wireless signal is the highest, the transmitting power of wireless signal can be lowered.
Below the specific embodiment of technical solution of the present invention is described in further detail.
Fig. 1 is the flow chart dynamically adjusting the method launching power of the embodiment of the present invention, as it is shown in figure 1, the method that power is launched in the dynamically adjustment of the embodiment of the present invention comprises the following steps:
Step 101: obtain the performance number of wireless signal；
Concrete, received wireless signal is sampled, and calculates the average power content of wireless signal after sampling, as the performance number of described wireless signal.
Why wireless signal average power content after sampling is determined whether to be positioned at threshold range etc. by this step as the performance number of this wireless signal, the transmission medium impact in the external world mainly it is vulnerable in view of wireless signal, the reception power of wireless signal may be by large effect, therefore, by receiving the meansigma methods of power, the external environment impact on radio signal power can be reduced, to avoid the mistuning launching power whole.
Or, by directly measuring the reception power of wireless signal, thus obtain the performance number of received wireless signal.
Step 102: judge whether described performance number is positioned at default threshold range, terminates currently processed flow process when being, be not located at during the threshold range preset performing step 103.
By the performance number of the received wireless signal that step 101 obtains, to determine whether this performance number is positioned at default threshold range.In the present invention, it is believed that when the reception power of wireless signal is positioned at default threshold range, the high-quality demodulation to wireless signal can be realized, can guarantee that radio communication quality.If the power that receives of wireless signal is less than the lower limit of threshold range, i.e. thinks that current radio signal power is too low, communication quality can be affected, transmitting power need to be increased；If the power that receives of wireless signal is more than the higher limit of threshold range, i.e. thinks that current radio signal power is the highest, the waste launching power can be caused, transmitting power need to be reduced.Owing to bluetooth equipment has equity, the bluetooth equipment of opposite end may there is also Similar Problems.Therefore, the present invention i.e. can determine that by receiving the power situation of signal the power of local terminal bluetooth equipment adjusts situation.
Step 103: adjust and launch power.
In the present invention, the mode adjusting transmitting power has multiple, introduces it individually below.
The first launch power adjust mode by: when the performance number of receptions wireless signal is more than the higher limit of threshold range preset determining, reduce transmitting power.When the performance number determining received wireless signal is less than the lower limit of the threshold range preset, increases and launch power.This power adjusts mode, can be simply considered that the transmitting terminal of wireless signal is the most suitable with the transmitting watt level of receiving terminal, once receiving terminal determines its wireless signal received lower limit less than the threshold range preset, i.e. think that the transmitting power of self is the least, need maximum transmission power；Corresponding, once receiving terminal determines its wireless signal received higher limit more than the threshold range preset, and i.e. thinks that the transmitting power of self is relatively big, belongs to waste and launch the phenomenon of power, needs to lower and launch power.In the present invention, the concrete numerical value lowering transmitting power or increase transmitting power is not construed as limiting, and can be a fixed numbers.
The second launches power adjustment mode:
For different transmitting power setting class letters；Bluetooth equipment is loaded with the class letter information corresponding with described wireless signal transmission power in the wireless signal launched.It is to say, carry the class letter that this wireless signal transmission power is corresponding in wireless signal, receiving terminal i.e. can determine that the emitting power grade of this wireless signal according to the wireless signal received, and then determines that its transmitting power is much.
So, when determining the higher limit that described performance number is more than the threshold range preset, the transmitting power that power is adjusted to the correspondence of the class letter identifying the low lower level of corresponding transmitting power than received wireless signal middle grade will be launched, maybe transmitting power is reduced setting threshold value；When determining the lower limit that described performance number is less than the threshold range preset, the transmitting power that power is adjusted to more corresponding than the class letter launching the high upper grade of power of received wireless signal middle grade mark correspondence will be launched, maybe will launch power and increase setting threshold value.
Assuming that the transmitting power that bluetooth equipment is supported has eight grades, respectively grade 1 ~ 8, the transmitting power of its correspondence is respectively 2.5mW, 5mW, 7.5mW, 10mW, 12.5mW, 15mW, 17.5mW, 20mW.And the threshold range preset is 0.5mW ~ 1mW, say, that for bluetooth equipment, no matter its mutual distance is how far, when the power of reception signal is positioned at 0.5mW ~ 1mW, communication quality can be ensured.
The grade assuming currently received signal is 3, and the transmitting power of its correspondence is 7.5mW；The reception power of received signal is 0.4mW, less than 0.5mW, now needs to increase to launch power, as increased a grade, is launched power and be adjusted to 10mW；It is of course also possible to power will be launched increase a setting threshold value, as increased 2mW, it is adjusted to 9.5mW by currently launching power；And if the reception power of received signal is 1.1mW, more than 1mW, now need to reduce to launch power, as a grade can be reduced, launched power and be adjusted to 5mW；It is of course also possible to power will be launched reduce a setting threshold value, as increased 2mW, it is adjusted to 9.5mW by currently launching power.After adjusting power, still monitoring receives the transmitting power of signal in real time, the most suitable to determine whether transmitting power, makes corresponding power of launching and adjusts.
The third launches power adjustment mode:
In the present invention, perform step 102 judge whether performance number is positioned at default threshold range before, further comprise the steps of:
Determine that in received wireless signal, whether power grade launches, more than or less than current, the power grade that power is corresponding, is adjusted to, by currently launching power, the transmitting power that power grade in received wireless signal is corresponding when being.
The present invention is before performing step 102, it needs to be determined that currently launch whether whether power mate with the transmitting power of received wireless signal, i.e. determine that the bluetooth equipment of receiving terminal and transmitting terminal is whether with the wireless signal of identical transmitting power emission, if the wireless signal of the transmitting power emission to differ, identical transmitting power need to be adjusted to, then the transmitting power carrying out wireless signal adjusts.
It will again be assumed that the transmitting power that bluetooth equipment is supported has eight grades, respectively grade 1 ~ 8, the transmitting power of its correspondence is respectively 2.5mW, 5mW, 7.5mW, 10mW, 12.5mW, 15mW, 17.5mW, 20mW.And the threshold range preset is 0.5mW ~ 1mW.
The grade assuming currently received signal is 3, and the transmitting power of its correspondence is 7.5mW, and current transmitting power is 10mW, and corresponding emitting power grade is 4；Now, arrange according to the transmitting power adjustment of bluetooth equipment, during such as current transmitting power less than received signal emitting power grade, by current transmitting power being adjusted to the performance number that received signal emitting power grade is corresponding, do not adjust；If according to this Adjustment principle, receiving terminal need not adjust current transmitting power, the most still launches wireless signal with 10mW；If transmitting terminal is also this Adjustment principle, it needs to adjust transmitting power is 10mW.Or, when current transmitting power is more than received signal emitting power grade, by current transmitting power being adjusted to the performance number that received signal emitting power grade is corresponding, do not adjust；If according to this Adjustment principle, it is 7.5mW that receiving terminal need to adjust current transmitting power；If transmitting terminal is also this Adjustment principle, it need not adjust launches power.Receiving terminal be adjusted to the transmitting power of transmitting terminal equal after, then carry out power by the aforesaid mode of the present invention and adjust.
The grade assuming currently received signal is 3, and the transmitting power of its correspondence is 7.5mW；The reception power of received signal is 0.4mW, less than 0.5mW, now needs to increase to launch power, as increased a grade, is launched power and be adjusted to 10mW；It is of course also possible to power will be launched increase a setting threshold value, as increased 2mW, it is adjusted to 9.5mW by currently launching power；And if the reception power of received signal is 1.1mW, more than 1mW, now need to reduce to launch power, as a grade can be reduced, launched power and be adjusted to 5mW；It is of course also possible to power will be launched reduce a setting threshold value, as increased 2mW, it is adjusted to 9.5mW by currently launching power.After adjusting power, still monitoring receives the transmitting power of signal in real time, the most suitable to determine whether transmitting power, makes corresponding power of launching and adjusts.
