All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Preferably, in this embodiment, the Signal Strength value of the wifi Signal may be obtained by reading an RSSI (Received Signal Strength Indication) parameter of the terminal; the signal quality value of the wifi signal may be obtained by reading the Score (signal quality Score) of the terminal. And the signal quality value of the wifi signal is obtained by statistics according to one or more parameters of the error rate, the retransmission rate and the packet loss rate of the wifi signal transmission data.
Preferably, in this embodiment, the terminal temporarily caches the signal intensity value of the wifi signal when reading the signal intensity value of the received wifi signal, so that when the terminal reads the signal intensity value of the wifi signal again, the difference between the currently read signal intensity value and the cached signal intensity value read last time is calculated to obtain the signal intensity value of the wifi signal. For example: if the signal intensity value of the wifi signal read last time is-70 and the signal intensity value of the wifi signal read currently is-50, the signal intensity variation value of the wifi signal is 20 which is the difference between the signal intensity value-70 of the wifi signal read currently and the signal intensity value-50 of the wifi signal read last time.
In S102, it is determined whether the signal strength variation value or the signal quality value meets a preset power adjustment trigger condition, and if the signal strength variation value or the signal quality value meets the power adjustment trigger condition, the process proceeds to step S103.
Preferably, in this embodiment, the preset power adjustment trigger condition includes a power-down operation trigger condition and a power-up operation trigger condition.

Fig. 2 is a schematic flow chart of a transmit power adjustment method according to a second embodiment of the present invention. Referring to fig. 2, the present embodiment provides a method for adjusting transmit power, including:
in S201, a signal strength variation value or a signal quality value of the wifi signal is obtained, where the signal strength variation value is a difference between a currently read signal strength value and a previously read signal strength value.
Since the implementation manner of step S201 is completely the same as that of the embodiment shown in fig. 1, it is not described herein again.
Preferably, in this embodiment, before step S201, the method further includes:
and reducing the fixed transmission power values corresponding to various transmission modes in a standard mapping relation table of the transmission rate modes and the fixed transmission power configured in the terminal by taking a preset power value as a unit so as to prepare a mapping relation table of a plurality of groups of transmission rate modes and the fixed transmission power values.
Preferably, in this embodiment, the preset power value is 0.5 dB. In this embodiment, since the fixed transmission power values in the fixed transmission power table corresponding to each transmission rate system are all reduced by 0.5dB, a mapping relationship table of multiple groups of transmission rate systems and fixed transmission power values is prepared, so that each transmission rate system can correspond to multiple fixed transmission power values and can be selected.
Preferably, in this embodiment, the mapping table of the multiple sets of transmission rate systems and the fixed transmission power values is named in a specific manner, for example: if the standard mapping table is named "0", a mapping table that is lowered by one 0.5dB unit is named "m 0.5", and a mapping table that is lowered by two 0.5dB units is named "m 1.0", where m represents a negative value. This naming is convenient for subsequent selection when adjusting power.
In S202, it is determined whether the signal strength variation value or the signal quality value meets a preset power-down operation trigger condition, and if the signal strength variation value or the signal quality value meets the power-down operation trigger condition, the process proceeds to step S203.

Preferably, in this embodiment, step S203 specifically includes:

transmitting a wifi signal by using the adjusted fixed transmitting power value, and judging whether the signal quality value of the wifi signal of the terminal is smaller than or equal to the first preset quality threshold value and larger than or equal to the second preset quality threshold value again;
if so, taking the currently selected mapping relation table as the first target mapping relation table, and ending the power reduction operation; or, continuing to execute the power reduction operation until a first target mapping relation table containing the lowest fixed transmission power value is selected;
if not, repeating the power reduction operation until the first target mapping relation table is selected;
or, if the signal quality value of the wifi signal of the terminal is still greater than the first preset quality threshold after traversing the multiple groups of mapping relation tables according to the power reduction operation, selecting a group of mapping relation tables with the lowest preset fixed transmission power value from the multiple groups of mapping relation tables, and transmitting the wifi signal by using the fixed transmission power value set in the mapping relation tables.
Preferably, in this embodiment, the first preset signal strength threshold is 5, the first preset signal quality threshold is 56, the second preset signal quality threshold is 54, and the third preset signal quality threshold is 60.
Preferably, in this embodiment, if the power down triggering condition is that "the difference is greater than a first preset signal strength threshold, and the signal quality value is greater than a first preset signal quality threshold", the preset adjustment step size is 0.5 dB; and if the power reduction triggering condition is that the absolute value of the difference value is smaller than or equal to the first preset signal strength threshold value and the signal quality value is a preset maximum signal quality threshold value, the adjusting step length is 1-2 dB.
It can be seen from the above that, according to the transmission power adjusting method provided by this embodiment, when the transmission frequency of the terminal is higher, the transmission power of the wifi signal can be reduced in real time according to the strength or quality of the received wifi signal, so that unnecessary power waste is reduced, and the power consumption of the terminal is reduced.

Preferably, in this embodiment, the preset power value is 0.5 dB. In this embodiment, since the fixed transmission power value in the fixed transmission power table corresponding to each transmission rate system is increased by taking 0.5dB as a unit, a mapping relationship table of multiple groups of transmission rate systems and fixed transmission power values is prepared, so that each transmission rate system can correspond to multiple fixed transmission power values and can be selected.
Preferably, in this embodiment, the mapping table of the multiple sets of transmission rate systems and the fixed transmission power values is named in a specific manner, for example: if the standard mapping table is named "0", a mapping table that is raised by one 0.5dB unit is named "p 0.5", and a mapping table that is raised by two 0.5dB units is named "p 1.0", where p represents a positive value. This naming is convenient for subsequent selection when adjusting power.
In S302, it is determined whether the signal strength variation value or the signal quality value meets a preset power-up operation trigger condition, and if the signal strength variation value or the signal quality value meets the power-up operation trigger condition, the process proceeds to S303.

Preferably, in this embodiment, step S303 specifically includes:
selecting a mapping relation table which is m units of preset power values lower than the current transmitting power value of the terminal from the multiple groups of mapping relation tables according to preset adjusting step lengths, wherein m is a positive integer, and adjusting the transmitting power of the wif signal according to the selected mapping relation table;
transmitting a wifi signal by using the adjusted fixed transmitting power value, and judging whether the signal quality value of the wifi signal of the terminal is smaller than or equal to the first preset quality threshold value and larger than or equal to the second preset quality threshold value again;
if so, taking the currently selected mapping relation table as the second target mapping relation table, and ending the power-up operation; or continuing to execute the power-up operation until a first target mapping relation table containing the highest fixed transmission power value is selected;
if not, repeating the power-up operation until the second target mapping relation table is selected;
or, if the signal quality value of the wifi signal of the terminal is still smaller than the second preset quality threshold after traversing the multiple groups of mapping relation tables according to the power-up operation, selecting a group of mapping relation tables with the highest preset fixed transmission power value from the multiple groups of mapping relation tables, and transmitting the wifi signal by using the fixed transmission power value set in the mapping relation tables.
Preferably, in this embodiment, the second preset signal strength threshold is-5, the first preset signal quality threshold is 56, and the second preset signal quality threshold is 54.
Preferably, in this embodiment, if the power-up triggering condition is that "the difference is smaller than the negative first preset signal strength threshold, where the first preset signal strength threshold is a positive number", the preset adjustment step is 0.5 dB; and if the power-up triggering condition is that the signal quality value of the wifi signal is smaller than a second preset signal quality threshold, and the second preset signal quality threshold is smaller than the first preset signal quality threshold, the preset adjusting step length is 1-2 dB.
Above can be seen, the transmission power adjusting method provided by the embodiment also automatically increases the transmission power of the wifi signal according to the strength or quality of the wifi signal received by the terminal when the transmission frequency of the terminal is low, so that the influence of the disconnection on the use of the user is avoided, and the user experience is further improved.
