The intelligent switch 11 is connected to the gateway 12, and performs wireless communication with the gateway 12.

For example, if the control object of the intelligent switch is a lamp, the server receives the light sensing data sent by the light sensing device, and determines whether the lamp needs to be turned on, turned off, turned on or dimmed according to the light sensing data and the brightness range preset by the user. For example, if the control object of the intelligent switch is an air conditioner, the server may generate a corresponding control instruction at a corresponding time point according to the on-time and off-time of the air conditioner preset by the user.

Furthermore, the different modes can correspond to different power adjustment strategies, the power adjustment strategies can be stored in the intelligent switch, the intelligent switch determines the signal strength of the response signal after receiving the response signal, and then determines the transmitting power for sending the inquiry signal next time according to the power adjustment strategies stored in the intelligent switch; the power adjustment strategy can also be stored on the terminal or the server, the intelligent switch can send the signal strength information to the terminal or the server after determining the signal strength of the response signal, the terminal or the server determines the transmitting power for sending the inquiry signal next time according to the stored power adjustment strategy and sends the determined transmitting power to the intelligent switch, and the intelligent switch sends the inquiry signal next time by using the transmitting power.
In the following, a specific implementation that the intelligent switch provides communication stability by adjusting the transmission power is described by taking a control object of the intelligent switch as an example and through several embodiments.
Fig. 2 is a flowchart illustrating a first embodiment of a power adjustment method according to an exemplary embodiment. As shown in fig. 2, the power adjustment method includes:
s101: and detecting the received response signal to acquire the signal strength of the response signal.
In this step, the intelligent switch may receive the instruction information from the server or the terminal device through the response signal sent by the gateway in the communication environments such as Zigbee protocol (Zigbee), Bluetooth Low Energy (BLE), and SUB-1G, and may receive the instruction information from the server or the terminal device through the response signal sent by the router in the WIFI communication environment.
Wherein, the gateway or the router returns a response signal after receiving the inquiry signal sent by the intelligent switch. The intelligent switch receives the response signal, detects the response signal and acquires the signal intensity of the response signal.
S102: and determining the transmitting power of the next transmitted inquiry signal according to the signal strength of the response signal.
Through the signal strength of the response signal, whether the signal strength is affected by some factors in the communication process or not can be reflected, and the problem of poor current communication quality is caused, for example, in the communication process, the current communication quality is affected due to the fact that objects such as doors, furniture and walls are shielded. If the communication quality is not good, the transmission power needs to be correspondingly improved to ensure the stability of the communication, and the transmission power can be reduced after the communication quality is recovered, so that excessive influence on the endurance of the battery is avoided.
Therefore, it is necessary to determine the condition of the communication quality and the magnitude of the transmission power of the next transmitted inquiry signal according to the signal strength of the response signal.
The power adjustment method provided in this embodiment determines the transmission power of the next inquiry signal by detecting the strength of the received response signal, and can adjust the transmission power of the inquiry signal at any time according to the strength of the response signal, instead of transmitting the inquiry signal at a fixed transmission power. The battery endurance is improved while the communication stability is maintained.
On the basis of the above embodiment, before receiving the response signal, the power adjustment method further includes:
the intelligent switch is preset with an inquiry period and/or a sleep period, transmits an inquiry signal at a preset frequency in the inquiry period according to the preset inquiry period, and enters a sleep state in a non-inquiry period (i.e. the sleep period) according to the preset inquiry period so as to reduce power consumption. The interrogation period and sleep period may be alternating time periods, such as a time period corresponding to an interrogation period followed by a time period corresponding to a non-interrogation period, then a time period corresponding to an interrogation period, and so on.
In one implementation, in an inquiry period, a preset frequency on the intelligent switch is equivalent to preset inquiry time intervals, namely, an inquiry signal is sent once every other inquiry time interval, namely, the inquiry signal is sent when each inquiry moment comes, and after the inquiry period is ended, namely, a non-inquiry period enters a sleep state; and after the non-inquiry period is finished, automatically waking up and entering the inquiry period again.
Or,
the intelligent switch presets an inquiry time interval, transmits an inquiry signal when each inquiry time arrives, and enters a dormant state at a non-inquiry time in the inquiry time interval.
The intelligent switch sends an inquiry signal to the gateway or the router according to a preset inquiry period and/or a preset inquiry time interval so as to acquire the response signal and the instruction information sent by the server carried in the response signal. It should be understood that the preset frequency for transmitting the query signal may be set according to the actual application, and when the preset frequency is sufficiently small, it may be understood that the query signal is transmitted to the gateway or the router in real time to obtain the response signal.
On the basis of the foregoing embodiments, in a specific implementation manner, determining the transmission power of the next inquiry signal to be sent according to the signal strength of the response signal includes: and acquiring the transmitting power of the next inquiry signal transmitting corresponding to the signal strength according to the corresponding relation between the preset signal strength and the transmitting power of the inquiry signal transmitting. Specifically, a corresponding relationship between the signal strength and the transmission power for sending the inquiry signal is preset in the intelligent switch, the corresponding relationship is a one-to-one corresponding relationship between the signal strength and the transmission power, according to the currently obtained signal strength, the corresponding relationship between the preset signal strength and the transmission power for sending the inquiry signal is searched in a traversing or comparing manner, the corresponding transmission power is obtained, and the transmission power is used as the transmission power for sending the inquiry signal next time.
Or, determining the transmission power of the next inquiry signal according to the signal strength of the response signal, including the specific steps shown in fig. 3, where fig. 3 is a flowchart illustrating a second embodiment of the power adjustment method according to an exemplary embodiment. The steps shown in fig. 3 include:
s201: and determining the signal intensity range to which the signal intensity belongs according to the corresponding relation between the preset signal intensity range and the transmitting power for transmitting the inquiry signal.
The preset corresponding relationship between the signal strength range and the transmission power for sending the inquiry signal is a plurality of preset signal strength ranges and the transmission power for sending the inquiry signal corresponding to each strength range.
In this step, a signal strength range to which the signal strength of the current reply signal belongs is determined according to a plurality of preset signal strength ranges.
S202: the transmit power for the next interrogation signal to be transmitted is determined based on the intensity range.
According to the signal intensity range to which the signal intensity of the current response signal determined in step S201 belongs, the transmission power of the transmission inquiry signal corresponding to the signal intensity range is obtained, and the transmission power is used as the transmission power of the next transmission inquiry signal.
According to the power adjustment method provided by the embodiment of the disclosure, the signal intensity range to which the signal intensity of the currently received response signal belongs is determined, and the transmitting power for transmitting the inquiry signal next time is determined according to the corresponding relationship between the preset signal intensity range and the transmitting power for transmitting the inquiry signal, so that the accurate adjustment of the transmitting power is realized.
Or, determining the transmission power of the next inquiry signal according to the signal strength of the response signal, including the specific steps shown in fig. 4, where fig. 4 is a flowchart illustrating a third embodiment of the power adjustment method according to an exemplary embodiment.
In this embodiment, a first preset intensity and a second preset intensity are preset, where the first preset intensity and the second preset intensity are intensity thresholds preset according to specific devices, chips, and application scenarios, and respectively represent an upper threshold and a lower threshold of a signal intensity. The signal intensity of the current response signal is respectively compared with the first preset intensity and the second preset intensity, and the current communication quality and the power consumption condition are determined: if the signal strength is between the first preset strength and the second preset strength, the current communication quality and the power consumption condition both meet the requirements, and if the signal strength is greater than or equal to the first preset strength, the current communication quality meets the requirements, but the power consumption is too large, and the transmitting power for sending the inquiry signal next time needs to be reduced; if the signal strength is less than the second preset strength, the current communication quality is not good, and the transmitting power for sending the inquiry signal next time needs to be increased. As shown in fig. 4, the specific implementation steps are as follows:
s301: and in response to the signal strength being greater than or equal to the first preset strength, determining the power value after the current transmission power is reduced by the first preset power as the transmission power for next transmission of the inquiry signal.
In this step, when the signal strength is greater than or equal to the first preset strength, it represents that the current communication quality meets the requirement, but the power consumption is too large, the current transmission power needs to be reduced by the first preset power, and the reduced power value is used as the transmission power for sending the inquiry signal next time.
In a specific implementation manner, the method for reducing the current transmission power further includes reducing the current transmission power to a first power value, and optionally, the preset power value may be 0 dBm.
In a specific implementation, the first preset power may be 0, for example, the current application modePriority ofAnd when the communication quality and the communication stability are ensured, the size of the signal intensity is not limited.
S302: and in response to the signal strength being less than the second preset strength, determining the power value after the current transmission power is increased by the second preset power value as the transmission power for next transmission of the inquiry signal.
In this step, when the signal strength is smaller than the second preset strength, which represents that the current communication quality is not good and cannot meet the communication requirement, the current transmission power needs to be increased by the second preset power value, and the increased power value is used as the transmission power for sending the inquiry signal next time.
In a specific implementation manner, the method for increasing the current transmission power further includes increasing the current transmission power to a second power value, and optionally, the preset power value may be 10 dBm.
The power adjustment method provided by the embodiment of the disclosure can determine that the current signal strength needs to increase the first preset power or decrease the second preset power according to the comparison result between the signal strength of the response signal and the preset strength, and use the increased or decreased power value as the transmission power for sending the inquiry signal next time. The current communication quality and the power consumption condition are determined by comparing the signal strength with the preset strength, and the transmitting power for sending the inquiry signal next time is further determined to be the power value of the current transmitting power after the current transmitting power is increased or reduced, so that the problems of large power consumption when the signal strength is greater than the first preset strength and unstable communication when the signal strength is less than the second preset strength are solved.
On the basis of the foregoing embodiments, in a specific implementation manner, the first preset power may be set to a sufficiently small value, for example, 1dBm, when the signal strength is greater than or equal to the first preset strength, it represents that the current communication quality meets the requirement, but the power consumption is too large, the current transmission power needs to be reduced by the first preset power, and the reduced power value is used as the transmission power for sending the query signal next time, and if it is determined that the signal strength of the response signal received next time is still greater than or equal to the first preset strength, the first preset power continues to be reduced for the next "current" transmission power until the signal strength is less than the first preset power.
Correspondingly, the second preset power may also be set to be sufficiently small, for example, 1dBm, when the signal strength is less than the second preset strength, which indicates that the current communication quality is not good and does not meet the communication requirement, the current transmission power needs to be increased by the second preset power, and the increased power value is used as the transmission power for sending the inquiry signal next time, and if it is determined that the signal strength of the response signal received next time is still less than the second preset strength, the second preset power is continuously increased for the next "current" transmission power until the signal strength is greater than or equal to the second preset power.
In some embodiments, a preset intensity may also be set, i.e. the first preset intensity and the second preset intensity may also be the same.
According to the power adjusting method provided by the embodiment of the disclosure, when the communication quality does not meet the requirement, the communication quality is improved by gradually increasing the transmitting power, and when the communication quality meets the requirement but the power consumption is too large, the power consumption is reduced by gradually reducing the transmitting power, so that the purpose of improving the communication stability is achieved while the unnecessary power loss is not increased.
