Description
Technical Field
The present application relates to a cluster terminal technology, and in particular, to a power saving method for a cluster terminal.
Background
The cluster terminal is used as a professional terminal, and the main working scene is that a loudspeaker is externally arranged, so that a user can clearly obtain information or instructions, and the cluster terminal has high requirements on standby capability. The horn is a high-energy-consumption device, and has a large influence on the standby capability of the terminal.
Disclosure of Invention
The application provides a power saving method of a cluster terminal, which can effectively reduce the power consumption of the cluster terminal.
In order to achieve the purpose, the following technical scheme is adopted in the application:
a power saving method of a cluster terminal comprises the following steps:
periodically measuring noise by the cluster terminal, and calculating average noise amplitude and peak-to-average ratio in a set time period;
determining the noise level of the current measurement according to the result of the noise measurement, and determining the loudness gain reduction value of the current measurement according to the preset corresponding relation between the noise level and the loudness gain reduction value;
adjusting the loudspeaker external loudness of the cluster terminal according to the determined loudness gain reduction value;
and in the corresponding relation between the noise level and the loudness gain, the larger the noise level is, the smaller the loudness gain reduction value is.
Preferably, the ambient noise within the time period is set.
Preferably, when the noise level of the current measurement is determined, if the calculated peak-to-average ratio is greater than the set noise peak-to-average ratio threshold, the adjustment of the loudness gain of the current measurement is not performed, and the next noise measurement is waited.
Preferably, if the trunking terminal is in an RRC connected state or a trunking listening state, the noise measurement is not performed.
According to the technical scheme, the cluster terminal periodically measures noise and calculates average noise amplitude and peak-to-average ratio in a set time period; determining the noise level of the current measurement according to the result of the noise measurement, and determining the loudness gain reduction value of the current measurement according to the preset corresponding relation between the noise level and the loudness gain reduction value; and adjusting the loudspeaker external loudness of the cluster terminal according to the determined loudness gain reduction value. In the correspondence relationship between the noise level and the loudness gain, the larger the noise level is, the smaller the loudness gain reduction value is. Through the processing, the loudspeaker external-radiation loudness of the cluster terminal can be periodically adjusted according to the detected environmental noise, and on the basis of ensuring that a user can clearly obtain information or instructions, the energy consumption of the cluster terminal is reduced to the maximum extent, so that the purpose of saving electricity is achieved.

fig. 2 is a diagram illustrating the relationship between the noise level and the loudness gain reduction value.
Detailed Description
For the purpose of making the objects, technical means and advantages of the present application more apparent, the present application will be described in further detail with reference to the accompanying drawings.
As mentioned above, the main working scene of the cluster terminal is loudspeaker play. To reduce the power consumption of the trunking terminal, controlling the loudness of the horn is a feasible way. However, simply reducing the loudness of the horn may cause the user to hear unclear messages or instructions. Based on this, the application provides a power saving method, which adaptively adjusts the loudness of the loudspeaker of the cluster terminal according to the magnitude of the environmental noise, so as to reduce the power consumption of the cluster terminal as much as possible on the premise of ensuring that a user can hear messages or instructions.
Fig. 1 is a basic flowchart of a power saving method for a cluster terminal in the present application. In the method, the trunking terminal periodically performs noise measurement and adjustment of the loudness of the horn. As shown in fig. 1, the method includes:
Specifically, when the trunking terminal performs noise measurement, the microphone may be turned on according to a set period, the ambient noise in a set time period is picked up, and the average noise amplitude and the peak-to-average ratio of the ambient noise are calculated.
Wherein, the period of noise measurement and the set time period can be set according to actual needs. Generally, the ambient noise is generally stationary noise, and the peak-to-average ratio is low. Therefore, preferably, a threshold value noiseppapr _ Th of the ambient noise peak-to-average ratio may be set, and if the noise peak-to-average ratio obtained by the noise measurement is greater than noiseppapr _ Th, it is indicated that the noise measurement has non-stationary noise, the measurement result is inaccurate, the current update is ended, and the measurement of the next period is waited to be performed, that is, the loudness of the horn is not updated, and the previous horn loudness value is maintained.
In addition, if the system is in the RRC connected state or the cluster monitoring state, the noise measurement is not performed, the update is finished, and the measurement in the next period is waited to be performed.
And 102, determining the noise level measured at the current time according to the noise measurement result in the step 101, and determining the loudness gain reduction value at the current time according to the preset corresponding relation between the noise level and the loudness gain reduction value.
For the purpose of saving power, when the ambient noise is relatively small, the loudness of the loudspeaker radiation can be considered to be reduced. Thus, noise is pre-staged and corresponding loudness gain reduction values are set for different noise levels. Wherein the larger the noise level, the smaller the loudness gain reduction value. Thus, when the noise is smaller and smaller, the loudness value is reduced continuously to achieve the purpose of saving power.
For example, the Noise can be classified from strong to weak into Noise _ Num, assuming that 0 is lightest and Noise _ Num-1 is strongest. Accordingly, the loudness Gain reduction value is also divided into Gain _ Num levels, and assuming that 0 is the Gain unchanged, and Gain _ Num-1 is the maximum value of the reduction Gain. The specific correspondence is shown in fig. 2.
And 103, the cluster terminal adjusts the loudspeaker external loudness according to the current loudness gain reduction value.
By this point, the single loudness adjustment procedure in this application ends. And when the noise measurement time of the next period is up, returning to execute the step 101.
The foregoing is a specific implementation of the power saving method for the cluster terminal in this application. By the method, the monitoring terminal detects the noise of the surrounding environment, and the loudness of the terminal is adaptively matched according to the noise condition, so that the maximum loudness is provided in a high-noise scene, and the low loudness is provided in a low-noise scene, therefore, the power consumption of the terminal is reduced and the standby capability is improved under the condition that the use perception of a user is not influenced basically.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
