Background
In the related art, a radio frequency signal output from a radio transmitter is transmitted to a transmitting antenna through a feeder line, and then radiated in the form of electromagnetic waves by the transmitting antenna. After the electromagnetic waves reach the receiving antenna, they are fed to the radio receiver via a feeder line.

In this embodiment, a method for determining a transmission power of the first smart device is provided, and fig. 1 is a flowchart of a method for determining a transmission power according to one embodiment of the present application, as shown in fig. 1, where the flowchart includes the following steps:
step S102, obtaining a first parameter, a second parameter and a third parameter, wherein the first parameter is the maximum transmitting power obtained by testing the first intelligent equipment when leaving the factory, the second parameter is the power variation to be reduced, and the third parameter is the power variation to be increased;
step S104, the first parameter, the second parameter and the third parameter are adopted to determine the transmitting power to be used.
Through the steps, the first parameter, the second parameter and the third parameter can be obtained, the first parameter is the maximum transmitting power obtained by testing the first intelligent equipment when leaving the factory, the second parameter is the power variation to be reduced, the third parameter is the power variation to be increased, the transmitting power to be used is determined through the first parameter, the second parameter and the third parameter, the purpose of adjusting the instantaneous maximum power consumption of the WiFi equipment by adjusting the transmitting power of the WiFi is achieved, the energy consumption waste of the WiFi equipment is effectively reduced, meanwhile, the technical effect of effectively reducing the interference to other WiFi signals is achieved, and the technical problem that the energy consumption waste of the WiFi equipment is easily caused by the transmitting power value setting mode of the WiFi equipment in the related technology is solved.
In an alternative embodiment, the first smart device is in a Station (STA) mode (hereinafter also referred to as a WiFi device) and the second smart device is in an Access Point (AP) mode (hereinafter also referred to as an AP). The first smart device may respond by sending a probe frame to the second smart device and waiting for the second smart device to return an acknowledgement response to the first smart device. If the second smart device successfully receives the probe frame, an acknowledgement response is returned to the first smart device. And if the first intelligent device successfully receives the confirmation response, indicating that the first intelligent device has successfully accessed the second intelligent device.
Optionally, in step S102, acquiring the second parameter may include performing the steps of:
step S1021, a first range level to which a fourth parameter belongs in a first time period is obtained, wherein the fourth parameter is a signal strength indication of data received by a first intelligent device from a second intelligent device;
step S1022, comparing the first range level with a second range level to which the fourth parameter belongs in a second time period, and determining that the range level changes, wherein the second time period is a previous time period adjacent to the first time period;
step S1023, obtaining a second parameter based on the change of the range level.
Due to the signal strength of the data received by the WiFi receiver, for example: the received signal strength indicator (Received Signal Strength Indication, abbreviated as RSSI) is related to the transmit power of the transmitting end, the distance between the transmitting end and the receiving end, and the current surrounding environment. In an alternative embodiment, the following coarsely estimated calculation formula may be employed:
D＝10^((TxPower–RSSI)/(10*n))；
wherein, the actual meaning of each parameter mentioned in the calculation formula is as follows:
(1) TxPower is the transmit power of the transmitting end and is generally expressed as the received signal strength at a distance of 1 meter from the transmitting end;
(2) n is a path signal strength loss factor that is typically closely related to the current surrounding environment, such as: in an open environment, n can take a value of 2;
(3) RSSI is the signal strength received by the receiving end;
(4) D represents the distance between the transmitting end and the receiving end, and its calculation unit is meter.
For the AP in the home environment, since the TxPower is not different and the environmental factor n is relatively fixed, when the WiFi device in the home environment receives the data transmitted by the AP, the distance between the WiFi device and the AP can be calculated roughly according to the received signal strength.
Therefore, the transmitting power of the transmitting end can be dynamically adjusted by adjusting the value of the RSSI, so that the transmitting end is allowed to use lower transmitting power when the signal is strong, and the transmitting end is allowed to use higher transmitting power when the signal is weak. In addition, when the signal is extremely bad, the maximum transmitting power of the factory test is allowed to be used for transmitting data, so that the purpose of reducing the power consumption can be realized by using lower transmitting power in most cases. And meanwhile, the problem of reduced transmission success rate caused by reduced transmission power can be solved by adjusting the transmission power according to the received signal strength.
The first time period and the second time period may be flexibly set according to an actual application scenario, for example: 10 minutes. A plurality of RSSI instantaneous values can be calculated through data packets continuously transmitted by the AP in a first time period. For example:
RSSI = transmit power of AP + antenna gain of AP-space loss + antenna gain of WiFi device;
next, the average value of the current RSSI values (corresponding to the fourth parameter) is obtained by performing an average operation on the plurality of instantaneous RSSI values obtained in the first period. Then, determining a first range level to which the RSSI average belongs in the first time period, and acquiring a historical RSSI average in a second time period (namely, a previous time period adjacent to the first time period, for example, a previous 10 minutes), and further determining whether the range level is changed or not by comparing the first range level to which the current RSSI average belongs with the second range level to which the historical RSSI average belongs in the second time period. If the range level is unchanged, the amount of power change to be reduced does not need to be acquired. If the range level changes, further acquisition of the amount of power change to be reduced is required.
Optionally, in step S1023, obtaining the second parameter based on the range level change may include performing the steps of:
step S10231, searching a first power value corresponding to the first range level and a second power value corresponding to the second range level from a first preset mapping relation;
step S10232, calculating a second parameter by using the first power value and the second power value.
A first preset mapping relationship between range levels of a plurality of different RSSI values and a plurality of different power values may be preconfigured in the WiFi device. In an alternative example, the range levels of multiple different RSSI are obtained in dBm in the following division:
(1) Range level 1 (-30, -20);
(2) Range rating 2 (-40, -30);
(3) Range rating 3 (-50, -40);
(4) Range class 4 (-60, -50);
(5) The range rating 5 is (-70, -60).
On the premise that the communication transmission rate between the first intelligent device and the second intelligent device is relatively fixed, a corresponding power value can be configured for each range level. For example: range level 1 corresponds to power value P1, range level 2 corresponds to power value P2, range level 3 corresponds to power value P3, range level 4 corresponds to power value P4, range level 5 corresponds to power value P5.
Therefore, the first power value and the second power value can be used for calculating the second parameter by searching the first power value corresponding to the first range level and the second power value corresponding to the second range level from the first preset mapping relation. For example: the first range class to which the current RSSI average belongs is range class 3, which corresponds to power value P3, and the second range class to which the historical RSSI average belongs is range class 2, which corresponds to power value P2. Then the second parameter P m I.e. the amount of change between P2 and P3.
Optionally, in step S102, acquiring the third parameter may include performing the steps of:
step S1024, obtaining a third range class to which a fifth parameter belongs in a third time period, wherein the fifth parameter is a failure rate of sending data;
step S1025, comparing the third range level with a fourth range level to which the fifth parameter belongs in a fourth time period, and determining that the range level changes, wherein the fourth time period is a previous time period adjacent to the third time period;
in step S1026, a third parameter is acquired based on the change in the range level.
The third time period and the fourth time period may be flexibly set according to the actual application scenario, for example: 10 minutes. The fifth parameter may be determined by the number of data packets sent by the WiFi device to the AP and the number of successful responses received by the WiFi device during the third period of time. If the WiFi device sends a data packet to the AP and receives a successful response from the AP, the data packet is successfully transmitted. If the WiFi device sends a data packet to the AP but does not receive a successful response from the AP, the data packet transmission is failed. In an alternative example, assuming that N1 represents the number of successful responses received by the WiFi device after sending the data packet to the AP in the third period, and N2 represents the number of unsuccessful responses received by the WiFi device after sending the data packet to the AP in the third period, the failure rate of sending the data in the different periods can be calculated by using N2/(n1+n2). And determining whether the range level changes by acquiring a third range level to which the failure rate of transmitting data in the third time period belongs and a fourth range level to which the failure rate of transmitting data in the fourth time period belongs so as to compare the third range level with the fourth range level. If the range level is unchanged, the amount of power change to be added does not need to be acquired. If the range level changes, it is necessary to further acquire the amount of power change to be increased.
Optionally, in step S1026, obtaining the third parameter based on the range level change may include performing the steps of:
step S10261, searching a third power value corresponding to the third range level and a fourth power value corresponding to the fourth range level from the second preset mapping relation;
step S10262, calculating a third parameter by using the third power value and the fourth power value.
A second preset mapping relationship between the range class of the failure rates of the plurality of different transmission data and the plurality of different power values may be preconfigured in the WiFi device. In an alternative example, the range level of failure rate of a plurality of different transmission data is obtained in the following division manner, with the unit%:
(1) Range class 1 is [0, 1%);
(2) Range rating 2 is [1%, 2%);
(3) Range grade 3 is [2%, 3%);
(4) Range grade 4 is [3%, 4%);
(5) Range rating 5 is [4%, 5%).
On the premise that the communication transmission rate between the first intelligent device and the second intelligent device is relatively fixed, a corresponding power value can be configured for each range level. For example: range level 1 corresponds to power value P6, range level 2 corresponds to power value P7, range level 3 corresponds to power value P8, range level 4 corresponds to power value P9, and range level 5 corresponds to power value P10.
Therefore, the third parameter can be calculated by using the third power value and the fourth power value by searching the third power value corresponding to the third range level and the fourth power value corresponding to the fourth range level from the second preset mapping relation. For example: the third range class to which the failure rate of the current transmission data belongs is a range class 2 corresponding to the power value P7, and the fourth range class to which the failure rate of the history transmission data belongs is a range class 1 corresponding to the power value P6. Then the third parameter P i I.e. the amount of change between P6 and P7.
Optionally, in step S104, determining the transmission power to be used using the first parameter, the second parameter, and the third parameter may include performing the steps of:
step S1041, calculating a difference value between the first parameter and the second parameter to obtain an intermediate result;
step S1042, calculating the sum of the intermediate result and the third parameter to obtain the transmit power to be used.
WiFi equipment can calculate and obtain power variation P to be reduced of transmitting power according to RSSI m Meanwhile, according to the failure rate of the current transmitted data, the power variation P to be increased of the transmitting power is calculated i . Finally, the coefficient P will be reduced m And increaseCoefficient P i The combination is performed to form the current transmitting power, and the power required to be used when the data is currently transmitted is determined, namely, the finally determined transmitting power is as follows: p=p max -P m +P i 。
