Example two
Referring to fig. 2, a flowchart of a method for automatically adjusting transmit power according to a second embodiment of the present invention is shown, where the method for automatically adjusting transmit power includes:
step 201, receiving a radio frequency signal from a first terminal;
the first terminal transmits radio frequency signals to the space, and the second terminal receives the radio frequency signals transmitted by the first terminal.
Step 202, detecting signal strength indication information of the radio frequency signal;
the second terminal detects the signal strength indication information of the radio frequency signal, for example, the second terminal is an interphone with the maximum power of 4W, and the value range of the received signal strength indication RSSI is [ -120dBm, 10dBm ].
Step 203, judging whether the signal intensity value of the radio frequency signal is within the signal intensity range for realizing the stable conversation of the second terminal;
and judging whether the signal intensity value of the received radio frequency signal is within a signal intensity range for realizing stable conversation of the second terminal, wherein the signal intensity range for realizing stable conversation of the second terminal is obtained through experimental tests, for example, the RSSI range for realizing stable conversation is [ -100dBm, -80dBm ] obtained through experimental tests of the interphone with the maximum power of 4W.
Step 204, if the signal intensity value is within the signal intensity range for realizing the stable conversation of the second terminal, detecting first position information included in the wireless radio frequency signal;
if the signal intensity value of the received wireless radio frequency signal from the first terminal is within the signal intensity range for realizing the stable call of the second terminal, the first position information of the first terminal included in the wireless radio frequency signal is detected. For example, the received RSSI value is-90 dBm, which is within the RSSI range of-100 dBm-80 dBm for achieving stable call of the second terminal.
Step 205, acquiring second position information of the second terminal;
the second terminal acquires second position information of the second terminal. Of course, if the signal strength value of the received radio frequency signal is within the signal strength range for realizing stable communication of the second terminal, the second terminal may also obtain the second location information of the second terminal first, and then the second terminal detects the first location information of the first terminal included in the radio frequency signal. Of course, the first location information and the second location information may be obtained simultaneously.
Step 206, judging whether the distance between the first position of the first terminal and the second position of the second terminal is changed;
and calculating the distance between the first position of the first terminal and the second position of the second terminal according to the first position of the first terminal and the second position of the second terminal, and judging whether the distance between the first position of the first terminal and the second position of the second terminal changes.
Due to the fact that the accuracy of the received signal strength of the terminal is limited, particularly the real-time change of the received signal strength detected by the terminal is relatively slow, and the detection result is the same RSSI value after a long time, the transmission power of the second terminal is adjusted in an auxiliary mode by judging the change of the position distance between the two terminals, and the adjustment of the transmission power is more timely and accurate.
Step 207, if the distance between the first position of the first terminal and the second position of the second terminal is decreased, reducing the current transmitting power of the second terminal;
and if the received signal strength value is within the signal strength range for realizing the stable conversation of the second terminal, the signal strength value received by the second terminal is increased and the current transmitting power of the second terminal is reduced if the judgment result is that the distance between the first position of the first terminal and the second position of the second terminal is reduced.
The initial starting transmission power of the terminal is defaulted to be the maximum power, the transmission power is judged and adjusted according to the received signal strength value, and the grade setting for reducing or increasing the transmission power is specifically obtained according to a large number of experimental tests.

and if the received signal strength value is within the signal strength range for realizing the stable conversation of the second terminal, the signal strength value received by the second terminal is reduced and the current transmitting power of the second terminal is increased if the judgment result is that the distance between the first position of the first terminal and the second position of the second terminal is increased.
Step 209, if the distance between the first position of the first terminal and the second position of the second terminal is not changed, maintaining the current transmission power of the second terminal;
and if the received signal strength value is within the signal strength range for realizing the stable conversation of the second terminal, and the received signal strength value of the second terminal is unchanged if the judgment result shows that the distance between the first position of the first terminal and the second position of the second terminal is unchanged, the current transmitting power of the second terminal is kept.
Step 210, if the signal intensity value is higher than the signal intensity highest threshold value for realizing stable conversation of the second terminal, reducing the current transmitting power of the second terminal;
and if the received signal strength value is higher than the signal strength highest threshold value for realizing stable conversation of the second terminal, reducing the current transmitting power of the second terminal. Such as: the RSSI range for realizing the stable call of the second terminal is [ -100dBm, -80dBm ], the received RSSI value is-20 dBm, the RSSI value is higher than the highest threshold value of-80 dBm for realizing the stable call of the second terminal, and the current transmitting power of the second terminal is reduced.
Step 211, if the signal strength value is within the signal strength range for realizing the stable call of the second terminal, maintaining the current transmitting power of the second terminal;
and if the received signal strength value is within the signal strength range for realizing the stable conversation of the second terminal, keeping the current transmitting power of the second terminal. Such as: the RSSI range for realizing the stable call of the second terminal is [ -100dBm, -80dBm ], the received RSSI value is-90 dBm, the RSSI value is within the signal strength range for realizing the stable call of the second terminal, and the current transmitting power of the second terminal is maintained.
And step 212, if the signal strength value is lower than the signal strength minimum threshold value for realizing the stable call of the second terminal, increasing the current transmitting power of the second terminal.
And if the received signal strength value is lower than the signal strength minimum threshold value for realizing the stable conversation of the second terminal, increasing the current transmitting power of the second terminal. Such as: the RSSI range for realizing the stable call of the second terminal is [ -100dBm, -80dBm ], the received RSSI value is-110 dBm, the RSSI value is lower than the signal strength minimum threshold value of-100 dBm for realizing the stable call of the second terminal, and the current transmitting power of the second terminal is increased.
In summary, the method for automatically adjusting the transmission power provided in this embodiment receives the radio frequency signal from the first terminal; detecting signal strength indication information of the wireless radio frequency signal; judging whether the signal intensity value of the wireless radio frequency signal is within a signal intensity range for realizing stable conversation of the second terminal; if the signal intensity value is higher than the signal intensity highest threshold value for realizing stable conversation of the second terminal, reducing the current transmitting power of the second terminal; the problem of electric quantity consumption of the existing radio equipment for transmitting signals with fixed power is solved; meanwhile, the transmitting power of the second terminal is adjusted in an auxiliary mode by judging the position distance change between the two terminals, so that the adjusting of the transmitting power is more timely and accurate, the manual operation of a user is better avoided, the use experience of the user is improved, and the technical effect of saving electric quantity is achieved.
