Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. 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.
The embodiment discloses a method for adjusting the operating frequency of an interphone, which is applied to the interphone. Referring to fig. 1, this embodiment includes the steps of:
s101, detecting whether the operation mode of the interphone is switched or not;
if the switching of the running modes of the interphone is detected, S102 is executed;
and in the working process of the interphone, switching among the three operation modes according to the task to be executed.
And detecting whether the running modes of the interphone are switched or not in real time. For example, when the interphone is currently operated in the transmitting mode, whether the operating mode of the interphone is switched from the transmitting mode to the receiving mode or from the transmitting mode to the idle mode is detected; when the interphone runs in a receiving mode currently, detecting whether the running mode of the interphone is switched from the receiving mode to a transmitting mode or whether the running mode of the interphone is switched from the receiving mode to an idle mode; when the interphone runs in the idle mode currently, whether the running mode of the interphone is switched to a receiving mode from the idle mode or whether the running mode of the interphone is switched to a transmitting mode from the idle mode is detected.
And S102, adjusting the running frequency of the interphone to the running frequency corresponding to the switched running mode.
When the interphone runs in different running modes, the required frequencies for maintaining normal operation in the current running mode are different. For example, in idle mode, only 90Mhz is needed to maintain normal operation; in the receiving mode, the normal work can be maintained by 90 Mhz; in transmit mode, 130Mhz is required to maintain normal operation.
In the prior art, in order to ensure that the intercom can normally operate, the operating frequency of the intercom is usually set to be the maximum frequency required by the intercom to operate, i.e. the operating frequency 130Mhz capable of normally operating in the transmission mode. The intercom operates at a fixed frequency of 130Mhz, whether or not it is currently operating in the transmit mode. However, when the interphone works in the receiving mode, the interphone can work normally only by 90Mhz, and when the interphone works in the idle mode, the interphone can work normally only by 90 Mhz. Therefore, when the interphone runs in the receiving mode and the idle mode and runs at a fixed frequency, system resources are wasted, the power consumption of the system is high, and the standby time of the interphone is shortened.
In this embodiment, when it is detected that the operation mode of the intercom is switched, the operation frequency of the intercom is adjusted, so that the intercom operates according to the frequency corresponding to the switched operation mode when the intercom operates in the switched operation mode.
Specifically, when the operating mode of the intercom is switched, the method for adjusting the operating frequency of the intercom includes:
calculating to obtain an adjustment frequency by adopting PID operation of which the integral coefficient and the differential coefficient are both 0 and the proportional coefficient is a coefficient corresponding to the switched operation mode; and adjusting the operating frequency of the interphone to the adjusted frequency so that the interphone operates according to the frequency corresponding to the switched operating mode.
The formula of the PID operation is as follows: freq ═ P × PllPra; where P is the scaling factor, PllPra is the reference frequency, and Freq is the adjustment frequency. In this example, PllPra is 19.2 Mhz.
In the process of adjusting the operating frequency based on the PID, the proportional coefficient P is different because the operating modes after switching are different.
Specifically, if the switched operation mode is the transmission mode, P is 8, that is, if it is detected that the intercom is switched from the reception mode to the transmission mode or from the idle mode to the transmission mode, the proportionality coefficient is determined to be 8, an adjustment frequency of 153.6Mhz is obtained by calculation according to Freq being 8 × 19.2Mhz, and the operation frequency of the intercom is adjusted to 153.6 Mhz;
if the switched operation mode is the receiving mode, P is 5, namely if the interphone is detected to be switched from the transmitting mode to the receiving mode or from the idle mode to the receiving mode, the proportionality coefficient is determined to be 5, the adjustment frequency 96Mhz is obtained by calculating according to Freq, 5, 19.2Mhz, and the operation frequency of the interphone is adjusted to 96 Mhz;
if the switched operation mode is the idle mode, P is 5, namely, if the interphone is detected to be switched from the transmitting mode to the idle mode or from the receiving mode to the idle mode, the proportionality coefficient is determined to be 5, the adjustment frequency 96Mhz is obtained by calculating according to Freq being 5 × 19.2Mhz, and the operation frequency of the interphone is adjusted to 96 Mhz.
The adjustment frequencies in different operation modes calculated by the PID algorithm are the maximum frequencies in the operation mode. For example, 153.6Mhz is the maximum frequency in the transmit mode, indicating that all tasks in the transmit mode can be processed normally at this frequency of 153.6 Mhz; 96Mhz is the maximum frequency in the receive mode, indicating that all tasks in the receive mode can be processed normally at this frequency of 96 Mhz.
In practical applications, the reference frequency PllPra may be selected from other frequencies, and when the reference frequency changes, the proportionality coefficient P changes accordingly. As long as it is ensured that the calculated adjustment frequency can maintain normal operation in the operation mode.
Of course, under the condition that the reference frequency and the scaling factor are determined, the operating frequencies, i.e., the adjustment frequencies, respectively corresponding to the three different operating modes can be calculated and stored in advance. One way of implementation is to maintain the correspondence between the three different operating modes and the operating frequencies in the form of a mapping table.
When the switching of the operation mode of the interphone is detected, the operation frequency corresponding to the switched operation mode is searched from the mapping table, and the operation frequency of the interphone is adjusted to the operation frequency corresponding to the switched operation mode searched from the mapping table. The running frequency of the interphone can be quickly adjusted to the frequency corresponding to the running mode to run, and the problem that the running frequency is adjusted slowly to cause power consumption waste due to the fact that the interphone still runs at the unadjusted frequency in the frequency adjusting process is solved.
According to the technical scheme, whether the operation modes of the interphone are switched is detected in real time, and when the operation modes of the interphone are switched, the operation frequency of the interphone is adjusted to the frequency corresponding to the switched operation modes, so that the interphone can operate according to the frequency corresponding to the current operation mode in different operation modes, the problem that the interphone still operates at the maximum operation frequency in the operation mode that the interphone can normally operate without the maximum operation frequency is solved, power consumption of an interphone system is high, and standby time of the interphone is shortened is solved.
The embodiment provides another method for adjusting the operating frequency of an interphone, which is different from the method for adjusting the operating frequency of an interphone disclosed in the previous embodiment in that the previous embodiment describes a method for adjusting the operating frequency of an interphone when the operating mode of the interphone is detected to be switched; the present embodiment describes a method for adjusting the operating frequency of an intercom when the operating mode of the intercom is not switched, that is, the intercom operates according to a certain operating mode.
Referring to fig. 2, this embodiment includes the following steps:
s201, when the running mode of the interphone is not switched, detecting the working state of the interphone in the running mode;
if the working state of the interphone in the running mode is detected to be an idle state or a busy state, S202 is executed;
otherwise, controlling the interphone to operate according to the current operating frequency;
when the operation modes of the interphone are not switched, namely the interphone operates in a certain operation mode, the working state of the interphone in the operation mode is detected in real time. And dividing the working state according to the proportion of the idle time in unit time under the current operating frequency. One implementation mode is that a proportion range of idle time in unit time is preset, called a preset range, and if the proportion of the idle time in unit time under the current operation frequency is greater than the maximum value of the preset range, the working state is an idle state; and if the proportion of the idle time in the unit time under the current operating frequency is smaller than the minimum value of the preset range, the working state is a busy state.
In this embodiment, the proportion of the idle time in the unit time is used as an index for determining the work-busy level, but in other embodiments, other parameters may also be used as an index for determining the work-busy level, for example, the duration of the idle state in the unit time.
When the interphone runs in a certain running mode, the working state of the interphone in the running mode is detected.
If the proportion of the idle time in the unit time under the current operating frequency is detected to be larger than the maximum value of the preset range, determining that the working state is the idle state; if the proportion of the idle time in the unit time under the current operation frequency is smaller than the minimum value of the preset range, determining that the working state is a busy state;
if the working state of the interphone is detected to be an idle state or a busy state, S202 is executed;
if the proportion of the idle time in the unit time under the current operating frequency is detected to be within the preset range, controlling the interphone to operate according to the current operating frequency; i.e. not adjusting the operating frequency of the intercom.
S202, calculating to obtain an adjusting frequency based on PID operation;
in this embodiment, the operating frequency of the intercom is adjusted based on the PID closed-loop control with the proportionality coefficient of 0.
Specifically, the proportion of the idle time in unit time under the current operating frequency and the preset proportion of the idle time in unit time are obtained, and the difference value between the proportion of the idle time in unit time under the current operating frequency and the preset proportion of the idle time in unit time is calculated; and then, based on the difference, executing PID operation and calculating to obtain the adjusting frequency.
Performing PID operation by adopting a formula Freq ═ (I ∑ Idle + D ∑ Δ Idle) × PllPra; wherein, the proportional coefficient in the PID operation is 0; i is an integral coefficient, and D is a differential coefficient; Σ Idle is the accumulated difference, Δ Idle is the single difference, PllPra is the reference frequency, and Freq is the adjustment frequency. Preferably, in the embodiment, the integral coefficient I is 0.5, the differential coefficient D is 0.8, and PllPra is 19.2; for example, the preset range is 30% -60%, if it is detected that the proportion of the idle time in the unit time under the current operating frequency is 70%, and since 70% is greater than the maximum value 60% of the preset range, the working state is the idle state; the difference between 70% and 60% is calculated to be 10%, i.e., the single difference Δ Idle is 10%, and when the first execution is performed, the cumulative difference is equal to the single difference, and thus, the cumulative difference Σ Idle is 10%. The single difference 10% and the cumulative difference 10% are substituted into the formula Freq ═ (I ∑ Idle + D × Δ Idle) × PllPra, yielding the adjustment frequency Freq ═ (0.5 × 10% +0.8 × 10%) < 19.2 ═ 2.496 Mhz.
S203, detecting the working state of the interphone in the running mode under the adjusted frequency;
if the working state of the interphone in the running mode is not an idle state and is not a busy state, executing S204;
otherwise, returning to execute the step S202;
and after the adjusting frequency is calculated based on PID operation, detecting the working state of the interphone in the operating mode when the interphone operates in the adjusting frequency. The implementation manner of detecting the operating state of the intercom is the same as the implementation manner of detecting the operating state of the intercom in step S201. And will not be described in detail herein.
If the proportion of the idle time in the unit time is detected to be within the preset range when the interphone runs according to the adjusting frequency, executing S204;
if the fact that the proportion of the idle time in the unit time is greater than the maximum value of the preset range when the interphone runs according to the adjusting frequency is detected, namely the working state of the interphone is in the idle state, or the proportion of the idle time in the unit time is smaller than the minimum value of the preset range, namely the working state of the interphone is in a busy state, the fact that the adjusting frequency is not matched with a task currently executed by the interphone is indicated, and the running frequency of the interphone needs to be adjusted again; the step S202 is executed again.
Since it is detected that the ratio of the idle time in the unit time is not within the preset range when the interphone operates according to the adjustment frequency, the step S202 needs to be performed to adjust the current operating frequency of the interphone. Therefore, in order to avoid the dead cycle, a predetermined number of times may be set. Namely, after the operation of adjusting the running frequency of the interphone for the preset times is executed, when the interphone runs according to the adjusted frequency, the proportion of the idle time in unit time is still not in the preset range, the interphone runs directly according to the adjusted frequency obtained by the last calculation, and the step of adjusting the running frequency of the interphone is not executed in a circulating mode.
And S204, controlling the interphone to operate according to the adjusting frequency.
According to the technical scheme, in the embodiment, when the interphone runs in a certain running mode, the working state of the interphone in the running mode is detected, if the working state of the interphone is in an idle state or a busy state, it is indicated that the current running frequency of the interphone is not matched with the current task to be executed, specifically, when the interphone runs according to the current running frequency in the idle state, the interphone is in the idle state for a long time after completing the task to be executed, and the interphone still runs at the current running frequency in the idle state for a long time, so that the power consumption of a system is large; in a busy state, when the interphone runs according to the current running frequency, almost all resources are used for processing tasks, so that the speed of processing the tasks by the system is reduced, and the tasks to be executed cannot be normally processed; and calculating to obtain the adjusting frequency based on PID operation, and determining that the proportion of idle time in unit time is within the preset range when the interphone runs under the adjusting frequency, namely controlling the interphone to run according to the adjusting frequency obtained by calculation when the current running frequency of the interphone is matched with the current executed task. Because under different operation modes, the interphone can operate according to the frequency matched with the current task to be executed, the problem that the standby time of the interphone is seriously influenced due to high system power consumption caused by the fact that the interphone continuously operates under the maximum frequency in order to ensure that the interphone can normally process the task to be executed is solved.
Optionally, in practical applications, when the operating frequency of the intercom is adjusted, only the method for adjusting the operating frequency of the intercom shown in fig. 1 may be performed, that is, only when the operating mode of the intercom is switched, based on the PID operation in which the integral coefficient and the differential coefficient are both 0, the operating frequency of the intercom is quickly adjusted to the maximum frequency in the switched operating mode; the method for adjusting the operating frequency of the interphone shown in fig. 2 may also be executed, that is, when the interphone operates in a certain operating mode, the operating frequency of the interphone is adjusted to operate at a frequency matched with the task to be executed in the operating mode through at least one PID closed-loop control adjustment based on the PID operation with the proportionality coefficient of 0; of course, it is also possible to perform both the method of adjusting the operating frequency of the intercom shown in fig. 1 and the method of adjusting the operating frequency of the intercom shown in fig. 2. Specifically, the method for adjusting the operating frequency shown in fig. 1 is performed when the operating mode of the intercom is switched, and the method for adjusting the operating frequency shown in fig. 2 is performed when the operating mode of the intercom is not switched, that is, the intercom operates in a certain operating mode.
Referring to fig. 3, a diagram of the effect of the operating frequency of the intercom after respectively executing the methods for adjusting the operating frequency of the intercom shown in fig. 1 and fig. 2 under different conditions is shown. Compared with the prior art in which the interphone runs at a fixed frequency, in this embodiment, when the interphone runs in the idle mode, the system power consumption can be reduced by about 10mA at a rated voltage, when the interphone runs in the receiving mode, the system power consumption can be reduced by about 6mA at the rated voltage, and when the interphone runs in the transmitting mode, the system power consumption can be reduced by about 2mA at the rated voltage.
It can be seen that when the operation modes of the interphone are switched, the operation frequency of the interphone can be quickly adjusted to the maximum frequency in the switched operation mode by executing the method for adjusting the operation frequency of the interphone shown in fig. 1; since the intercom initially operates in a certain operation mode according to the maximum frequency in the operation mode adjusted by the adjustment method shown in fig. 1, however, when the intercom operates in the operation mode, the task to be executed can be normally processed without operating at the maximum frequency in the operation mode, and in the process of operating in the certain operation mode, after the intercom is adjusted by the adjustment method shown in fig. 2, the operation frequency is a process of reducing the operation frequency.

According to the technical scheme, whether the operation modes of the interphone are switched is detected in real time, and when the operation modes of the interphone are switched, the operation frequency of the interphone is adjusted to the frequency corresponding to the switched operation modes, so that the interphone can operate according to the frequency corresponding to the current operation mode in different operation modes, the problem that the interphone still operates at the maximum operation frequency in the operation mode that the interphone can normally operate without the maximum operation frequency is solved, power consumption of an interphone system is high, and standby time of the interphone is shortened is solved. And when the interphone runs in a certain running mode, detecting the working state of the interphone in the running mode, if the working state of the interphone is in an idle state or a busy state, and indicating that the current running frequency of the interphone is not matched with the current task to be executed, calculating to obtain an adjusting frequency based on PID (proportion integration differentiation) operation, and determining that the occupied proportion of the idle time in unit time is within the preset range when the interphone runs in the adjusting frequency, namely when the current running frequency of the interphone is matched with the current task to be executed, controlling the interphone to run according to the calculated adjusting frequency. Because under different operation modes, the interphone can operate according to the frequency matched with the current task to be executed, the problem that the standby time of the interphone is seriously influenced due to high system power consumption caused by the fact that the interphone continuously operates under the maximum frequency in order to ensure that the interphone can normally process the task to be executed is further solved.
