Embodiment
Basic thought of the present invention is: whether the performance number according to the opposite end wireless signal that receives is positioned at default threshold range, determines with this whether the wireless signal that receives is positioned within the performance number scope that can guarantee communication quality; If be positioned at described default threshold range, then wireless signal transmission power is not made adjustment; If be not positioned at described default threshold range, then need the transmitting power of current wireless signal is adjusted; Reduce the transmitting power of wireless signal in limited time when being higher than the upper of default threshold range, prescribe a time limit when being lower than the lower of default threshold range, increase the transmitting power of wireless signal.
Technical scheme of the present invention, the main theory foundation is when the received power of the wireless signal that receives is lower than the lower limit of setting threshold scope, will have influence on the communication quality of wireless signal; Because the transmitting-receiving of the wireless signal of bluetooth equipment is reciprocity, the opposite equip. of launching this wireless signal this moment receives wireless signal also may be weak and affect communication quality, therefore, in this case, need to increase transmitting power to guarantee the communication quality at bluetooth equipment two ends; And the received power of the wireless signal that receives is when being higher than the higher limit of setting threshold scope, although can guarantee the communication quality of wireless signal, but owing to the too high waste that causes transmitting power of transmitting power of wireless signal, can reduce the transmitting power of wireless signal.
The below is described in further detail the specific embodiment of technical solution of the present invention.
Fig. 1 is the flow chart of method of the dynamic adjustment transmitting power of the embodiment of the invention, and as shown in Figure 1, the method for the dynamic adjustment transmitting power of the embodiment of the invention may further comprise the steps:
Step 101: the performance number of obtaining wireless signal;
Concrete, the reception wireless signal is sampled, and the average power content of wireless signal behind the calculating sampling, as the performance number of described wireless signal.
Wireless signal average power content after why this step will sample determines whether to be positioned at threshold range etc. as the performance number of this wireless signal, mainly be to consider that wireless signal is vulnerable to extraneous transmission medium impact, the received power of wireless signal may be subject to larger impact, therefore, mean value by received power, can reduce external environment to the impact of radio signal power, whole with the mistuning of avoiding transmitting power.
Perhaps, by the received power of direct measurement wireless signal, thereby obtain the performance number of the wireless signal that receives.
Step 102: judge whether described performance number is positioned at default threshold range, finishes current handling process when being, execution in step 103 when being positioned at default threshold range.
The performance number of the wireless signal that receives that obtains by step 101 is to determine whether this performance number is positioned at default threshold range.Among the present invention, think when the received power of wireless signal is positioned at default threshold range, can realize the high-quality demodulation to wireless signal, can guarantee radio communication quality.If the received power of wireless signal is lower than the lower limit of threshold range, think that namely the current wireless signal power is excessively low, can affect communication quality, need to increase transmitting power; If the received power of wireless signal, thinks namely that the current wireless signal power is too high greater than the higher limit of threshold range, can cause the waste of transmitting power, need to reduce transmitting power.Because bluetooth equipment has equity, may also there be Similar Problems in the bluetooth equipment of opposite end.Therefore, the present invention can determine the power adjustment situation of local terminal bluetooth equipment by the power situation that receives signal.
Step 103: adjust transmitting power.
Among the present invention, the mode of adjusting transmitting power has multiple, below introduces respectively it.
The first transmitting power adjustment mode by: in the performance number of determining institute's receptions wireless signal during greater than the higher limit of the threshold range of presetting, the reduction transmitting power.In the performance number of determining the wireless signal that receives during less than the lower limit of the threshold range of presetting, the increase transmitting power.This power is adjusted mode, can think simply that the transmitting power size of the transmitting terminal of wireless signal and receiving terminal is substantially suitable, in case receiving terminal determines that its wireless signal that receives is less than the lower limit of default threshold range, think that namely the transmitting power of self is also less, need maximum transmission power; Corresponding, in case determining its wireless signal that receives, receiving terminal greater than the higher limit of default threshold range, thinks that namely the transmitting power of self is larger, belong to the phenomenon of wasting transmitting power, need the downward modulation transmitting power.Among the present invention, the concrete numerical value of downward modulation transmitting power or increase transmitting power is not construed as limiting, and can be a fixed numbers.
The second transmitting power adjustment mode is:
For different transmitting powers arranges class letter; Bluetooth equipment is loaded with the class letter information corresponding with described wireless signal transmission power in the wireless signal of launching.That is to say, carry class letter corresponding to this wireless signal transmission power in the wireless signal, receiving terminal can be determined the emitting power grade of this wireless signal according to the wireless signal that receives, and then determines that its transmitting power is much.
Like this, when determining described performance number greater than the higher limit of default threshold range, transmitting power is adjusted into the transmitting power of correspondence of the class letter of next low grade of the transmitting power more corresponding than reception wireless signal middle grade sign, or transmitting power is reduced setting threshold; When determining described performance number less than the lower limit of default threshold range, transmitting power is adjusted into transmitting power corresponding to class letter that identifies the high upper grade of corresponding transmitting power than reception wireless signal middle grade, or transmitting power is increased setting threshold.
Suppose that the transmitting power that bluetooth equipment is supported has eight grades, be respectively grade 1 ~ 8, its corresponding transmitting power is respectively 2.5mW, 5mW, 7.5mW, 10mW, 12.5mW, 15mW, 17.5mW, 20mW.And default threshold range is 0.5mW ~ 1mW, that is to say for bluetooth equipment, no matter how far its mutual distance has, and when the power that receives signal is positioned at 0.5mW ~ 1mW, can guarantee communication quality.
The grade of supposing current received signal is 3, and its corresponding transmitting power is 7.5mW; The received power of received signal is 0.4mW, is lower than 0.5mW, needs this moment to increase transmitting power, as increasing a grade, its transmitting power is adjusted into 10mW; Certainly, also transmitting power can be increased a setting threshold, as increasing 2mW, current transmit power is adjusted into 9.5mW; And if the received power of received signal is 1.1mW, greater than 1mW, need this moment to reduce transmitting power, as reducing a grade, its transmitting power is adjusted into 5mW; Certainly, also transmitting power can be reduced a setting threshold, as increasing 2mW, current transmit power is adjusted into 9.5mW.Behind the Modulating Power, whether still Real-Time Monitoring receives the transmitting power of signal, suitable to determine whether transmitting power, makes corresponding transmitting power adjustment.

Among the present invention, whether the performance number of judging of execution in step 102 is positioned at before the default threshold range, also comprises step:
Determine receive whether power grade is greater than or less than power grade corresponding to current transmit power in the wireless signal, when being current transmit power is adjusted into transmitting power corresponding to power grade in the wireless signal that receive.

The grade of supposing current received signal is 3, and its corresponding transmitting power is 7.5mW; The received power of received signal is 0.4mW, is lower than 0.5mW, needs this moment to increase transmitting power, as increasing a grade, its transmitting power is adjusted into 10mW; Certainly, also transmitting power can be increased a setting threshold, as increasing 2mW, current transmit power is adjusted into 9.5mW; And if the received power of received signal is 1.1mW, greater than 1mW, need this moment to reduce transmitting power, as reducing a grade, its transmitting power is adjusted into 5mW; Certainly, also transmitting power can be reduced a setting threshold, as increasing 2mW, current transmit power is adjusted into 9.5mW.Behind the Modulating Power, whether still Real-Time Monitoring receives the transmitting power of signal, suitable to determine whether transmitting power, makes corresponding transmitting power adjustment.
