Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. 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 application.
Referring to fig. 1, fig. 1 is a first flowchart illustrating a method for adjusting a transmission power of a bluetooth signal according to an embodiment of the present disclosure. The method for adjusting the transmission power of the Bluetooth signal comprises the following steps:
The first mobile terminal and the second mobile terminal can be terminal devices such as a mobile phone, a computer or a personal digital assistant, and the first mobile terminal and the second mobile terminal can transmit information through respective bluetooth modules.
Specifically, when the first mobile terminal and the second mobile terminal establish a communication connection through the bluetooth module, a communication protocol may be sent to the second mobile terminal, where the communication protocol is used to trigger the second mobile terminal to send the first signal strength to the first mobile terminal. Or directly setting the first signal intensity value sent by the second mobile terminal to the connecting device when the other mobile terminals establish communication connection through the Bluetooth module. The first signal strength value sent by the second mobile terminal is the signal strength value of bluetooth when the second mobile terminal receives the communication protocol or transmission data sent by the first mobile terminal.
In some embodiments, the receiving a first signal strength value sent by a second mobile terminal includes:
(1) and receiving the signal intensity values sent by the second mobile terminal every preset time length to obtain a plurality of signal intensity values.
(2) And if the difference value between any two signal strength values is smaller than a preset difference value, determining any one of the signal strength values as a first signal strength value.
The communication protocol may also be configured to trigger the second mobile terminal to send the signal strength value every other preset time period, or set the second mobile terminal to send the signal strength value every other preset time period. Therefore, the signal strength values sent by the second mobile terminal can be received. If the difference between any two signal strength values among the plurality of signal strength values is smaller than the preset difference, it can be proved that the distance between the first mobile terminal and the second mobile terminal is not changed greatly, and therefore the signal strength value is not changed greatly, and any one of the plurality of signal strength values can be determined as the first signal strength value.
And step 102, determining a first distance between the mobile terminal and the second mobile terminal according to the first signal strength value.
The mapping relationship between the signal strength value and the distance may be set in advance, so that when the first signal strength value is received, the first distance corresponding to the first signal strength value may be determined according to the mapping relationship.
In order to determine whether the first signal strength value can meet the data transmission condition or whether the parameter is set too large to cause electric quantity waste, a plurality of distance intervals can be set, and a preset signal strength value corresponding to each distance interval and meeting the data transmission condition is set, so that whether the first signal strength value can meet the data transmission condition or whether the parameter is set too large to cause electric quantity waste is determined according to the first signal strength value and the preset signal strength value of the distance interval where the first distance is located. Therefore, after the first distance corresponding to the first signal strength value is determined according to the mapping relationship, the first distance interval where the first distance is located can be determined, and the first preset signal strength value corresponding to the first distance interval is obtained.
And step 104, if the first signal strength value is not equal to the first preset signal strength value, acquiring a first target signal transmitting power corresponding to the first preset signal strength value.
The magnitude relation between the first signal strength value and the first preset signal strength value can be compared, and if the first signal strength value is not equal to the first preset signal strength value, it indicates that the current bluetooth signal transmitting power needs to be adjusted. For example: when the first signal strength value is smaller than a first preset signal strength value, the current first signal strength value cannot meet the data transmission condition; when the first signal strength value is greater than the first preset signal strength value, it indicates that the current first signal strength value can satisfy the data transmission condition, but the parameter set for bluetooth is too large, resulting in waste of electric quantity. Both of the above situations can be correspondingly improved by adjusting the current bluetooth signal transmission power.
Specifically, since the transmission power may affect the magnitude of the signal strength value, the corresponding relationship between the transmission power and the signal strength value may be set in advance, so that when it is determined that the first signal strength value is not equal to the first preset signal strength value, the first target signal transmission power corresponding to the first preset signal strength value may be obtained.
And 105, adjusting the current signal transmission power of the Bluetooth to a first target signal transmission power.
The current signal transmitting power is adjusted to the first target signal transmitting power, so that the problem that the data transmission condition cannot be met or the electric quantity is wasted due to overlarge set parameters is solved.
Specifically, the signal transmitting power is determined by the power supply current of the Bluetooth module, so that the signal transmitting power can be adjusted by adjusting the current. That is, the first target signal transmitting power corresponds to a first target current value. Furthermore, in order to avoid damage to the bluetooth module caused by a large adjustment span of the current when the current is adjusted, the current value of the bluetooth module can be adjusted in a step adjustment mode. Thus, in some embodiments, said adjusting the current signal transmit power of said bluetooth to said first target signal transmit power comprises:
(1) and acquiring a first target current value of the first target signal transmitting power.
(2) And step-by-step adjusting the current value of the Bluetooth according to a preset adjustment amplitude until the current value of the power supply current of the Bluetooth reaches the first target current value.
In some embodiments, the method further comprises:
(1.1) in the process of carrying out step adjustment on the current value according to a preset adjustment amplitude, if a second signal intensity value sent by a second mobile terminal is received, recording the second signal intensity value;
(1.2) after the current value of the power supply current of the Bluetooth is adjusted to the first target current value from the current value, adjusting the current value of the adjusted power supply current according to the second signal intensity value.
If the second mobile terminal sends the signal strength value to the first mobile terminal at the interval preset time length, the step adjustment process is not completed, that is, the signal strength value is not adjusted to the first target current value. The second signal intensity value can be recorded first, and after the current value of the Bluetooth is adjusted to the first target current value, the adjusted current value is adjusted according to the second signal intensity value.
In some embodiments, the method further comprises:
(1.1) if the first signal intensity value is smaller than a first preset signal intensity value, acquiring the data volume of the data to be transmitted;
(1.2) if the data volume is smaller than a preset data volume, executing step adjustment on the current value according to a preset adjustment amplitude until the current value of the power supply current of the Bluetooth reaches a first target current value;
(1.3) if the data volume is larger than a preset data volume, adjusting the current value to the first target current value.
And if the first signal intensity value is smaller than the first preset signal intensity value, the current value of the Bluetooth cannot meet the data transmission condition at present. Therefore, the data volume of the data to be transmitted can be obtained, the data to be transmitted can be data selected by a user, and if the data volume of the data to be transmitted is smaller than the preset data volume, the current value can be adjusted in a stepping adjustment mode; if the data to be transmitted is larger than the preset data volume, the data volume with the transmitted data is proved to be larger, and a large amount of time is needed for transmitting the data to be transmitted in a stepping adjustment mode, so that the current value can be directly adjusted to be the first target current value, the time for adjusting the current is shortened, and the data transmission efficiency is improved.
In some embodiments, the method further comprises:
(1.1) if the first signal intensity value is smaller than a first preset signal intensity value, acquiring transmission time of historical transmission data, wherein the historical transmission data is data transmitted to the second mobile terminal on the basis of a communication link corresponding to the communication connection;
(1.2) determining a preset transmission time according to the historical transmission data;
(1.3) if the transmission time is greater than a preset transmission time, executing a step of determining a first target current value corresponding to the first preset signal strength value.
And if the first signal intensity value is smaller than the first preset signal intensity value, the current value of the Bluetooth cannot meet the data transmission condition at present. Therefore, the transmission time of the historical transmission data transmitted to the second mobile terminal through the communication link corresponding to the communication connection can be obtained, and the preset transmission time required by the historical transmission data can be estimated. And when the transmission time is longer than the preset transmission time, executing the step of determining a first target current value corresponding to the first preset signal strength value. That is, if the transmission time is less than the preset transmission time, it indicates that the quality of the communication channel of the current communication link is high, and the data transmission of the bluetooth is not affected, and the signal transmission power of the bluetooth may not be adjusted.
As can be seen from the above, in the embodiment of the present application, when a communication connection is established with a second mobile terminal, a first signal strength value sent by the second mobile terminal is received; determining a first distance between the first mobile terminal and the second mobile terminal according to the first signal strength value; determining a first distance interval where the first distance is located, and acquiring a first preset signal strength value corresponding to the first distance interval; if the first signal intensity value is not equal to a first preset signal intensity value, acquiring a first target signal transmitting power corresponding to the first preset signal intensity value; and adjusting the current signal transmission power of the Bluetooth to the first target signal transmission power. The signal transmitting power of the transmitting signal can be dynamically adjusted, and the flexibility of the signal transmitting power is further improved.
In some embodiments, as shown in fig. 2, a method for adjusting the transmission power of a bluetooth signal is provided, and the method for adjusting the transmission power of the bluetooth signal includes:
step 201, when a communication connection is established with a second mobile terminal, receiving signal strength values sent by the second mobile terminal every preset time length to obtain a plurality of signal strength values.
When the first mobile terminal and the second mobile terminal establish communication connection through the Bluetooth module, a communication protocol can be sent to the second mobile terminal. The communication protocol may be to trigger the second mobile terminal to send the signal strength value every other preset time period, or to set the second mobile terminal to send the signal strength value every other preset time period. Therefore, the signal strength values sent by the second mobile terminal can be received.
Step 202, if the difference between any two signal strength values is smaller than the preset difference, determining any one of the signal strength values as a first signal strength value.
If the difference between any two signal strength values among the signal strength values is smaller than the preset difference, it can be proved that the distance between the first mobile terminal and the second mobile terminal is not changed greatly, and therefore the signal strength value is not changed greatly, and any one of the signal strength values can be determined as the first signal strength value.
The mapping relationship between the signal strength value and the distance may be set in advance, so that when the first signal strength value is received, the first distance corresponding to the first signal strength value may be determined according to the mapping relationship.
In order to determine whether the first signal strength value can meet the data transmission condition or whether the parameter is set too large to cause electric quantity waste, a plurality of distance intervals can be set, and a preset signal strength value corresponding to each distance interval and meeting the data transmission condition is set, so that whether the first signal strength value can meet the data transmission condition or whether the parameter is set too large to cause electric quantity waste is determined according to the first signal strength value and the preset signal strength value of the distance interval where the first distance is located. Therefore, after the first distance corresponding to the first signal strength value is determined according to the mapping relationship, the first distance interval where the first distance is located can be determined, and the first preset signal strength value corresponding to the first distance interval is obtained.
The magnitude relation between the first signal strength value and the first preset signal strength value can be compared, and if the first signal strength value is not equal to the first preset signal strength value, it indicates that the current bluetooth signal transmitting power needs to be adjusted. For example: when the first signal strength value is smaller than a first preset signal strength value, the current first signal strength value cannot meet the data transmission condition; when the first signal strength value is greater than the first preset signal strength value, it indicates that the current first signal strength value can satisfy the data transmission condition, but the parameter set for bluetooth is too large, resulting in waste of electric quantity. Both of the above situations can be correspondingly improved by adjusting the current bluetooth signal transmission power.
Specifically, since the transmission power may affect the magnitude of the signal strength value, the corresponding relationship between the transmission power and the signal strength value may be set in advance, so that when it is determined that the first signal strength value is not equal to the first preset signal strength value, the first target signal transmission power corresponding to the first preset signal strength value may be obtained.
Specifically, since the transmission power may affect the magnitude of the signal strength value, the corresponding relationship between the transmission power and the signal strength value may be set in advance, so that when it is determined that the first signal strength value is not equal to the first preset signal strength value, the first target signal transmission power corresponding to the first preset signal strength value may be obtained.
Specifically, the signal transmitting power is determined by the power supply current of the Bluetooth module, so that the signal transmitting power can be adjusted by adjusting the current. That is, the first target signal transmitting power corresponds to a first target current value.
And step 207, performing step adjustment on the current value of the Bluetooth according to a preset adjustment amplitude until the current value of the power supply current of the Bluetooth reaches a first target current value.
Specifically, in order to avoid damage to the bluetooth module caused by a large adjustment span of the current when the current is adjusted, the current value of the bluetooth module can be adjusted in a step adjustment manner.
As can be seen from the above, in the embodiment of the present application, when a communication connection is established with a second mobile terminal, a first signal strength value sent by the second mobile terminal is received; determining a first distance between the first mobile terminal and the second mobile terminal according to the first signal strength value; determining a first distance interval where the first distance is located, and acquiring a first preset signal strength value corresponding to the first distance interval; if the first signal intensity value is not equal to a first preset signal intensity value, acquiring a first target signal transmitting power corresponding to the first preset signal intensity value; and adjusting the current signal transmission power of the Bluetooth to the first target signal transmission power. The signal transmitting power of the transmitting signal can be dynamically adjusted, and the flexibility of the signal transmitting power is further improved.
