Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
The following disclosure provides many different embodiments, or examples, for implementing different structures of the invention. In order to simplify the present disclosure, components and arrangements of specific examples are described below. They are, of course, merely examples and are not intended to limit the invention. Furthermore, the present invention may repeat reference numerals and/or letters in the various examples. This repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed.
The application provides an energy-saving control method, an energy-saving control system, a communication terminal and a storage medium, which can further reduce power consumption and improve standby time of the communication terminal.
Fig. 1 is a flowchart of an energy-saving control method according to an embodiment of the present application, and as shown in fig. 1, an energy-saving control method is applied to a communication terminal, and includes:
step 101: the IQ signal is received and a state of the communication terminal is determined, the state including a power saving state and an operational state.
The communication terminal of the present application includes: at least one communication interface; at least one bus connected to the at least one communication interface; at least one processor coupled to the at least one bus; at least one memory coupled to the at least one bus, the processor configured to perform steps 101-105.
In a specific embodiment, the main frequencies of the power saving state and the operation state of the communication terminal are different in the application, so that the main frequencies of the communication terminals in different states are different. In the application, the main frequency difference between the power saving state and the running state is larger, and can reach ten times of the difference, for example, the main frequency of the running state is 192 MHz, and the main frequency of the power saving state is 19.2 MHz. The application can reduce the main frequency of the power saving state to a lower level because the power saving state only ensures that the IQ signal can be received, and in the prior art, even if the communication terminal is in the power saving state, most of the power consumption of a complete receiving link is required to be maintained, so the power consumption is higher.
In a specific embodiment, the main frequencies of the power saving state and the operation state are different, and the communication terminal switches the states by switching the main frequencies. Namely, in the application, different states of the communication terminal correspond to different frequencies, the switching state is the process of adjusting the frequency (including frequency up-conversion and frequency down-conversion), the control principle is simple, and the implementation is convenient.
In a specific embodiment, the power saving state corresponds to a first main frequency, the operating state corresponds to a second main frequency, and the first main frequency is smaller than the second main frequency. In the application, different main frequencies are used for distinguishing the power saving state and the running state, so that the power saving state works at a relatively low main frequency, thereby reducing the power consumption and improving the standby time of the communication terminal.
Step 102: and determining the energy intensity value of the IQ signal in a first preset time period.
It should be noted that the first preset duration is in the order of milliseconds, and is generally set to 5-10 milliseconds. The first preset duration can accurately reflect the energy intensity value within 5-10 milliseconds, if the duration is too long, for example, 5 seconds, the real-time change condition of the signal cannot be reflected, and if the duration is too short, for example, 1 millisecond, the first preset duration represents an instantaneous value, and the reference meaning is not great.
In addition, it should be mentioned that 5-10 ms is a preferred duration, and the specific duration may be set according to practical situations, which is not limited by the present application.
In a specific embodiment, the energy intensity values include a first energy value of the effective signal and a second energy value of the noise signal, and determining the energy intensity value of the IQ signal for a first preset duration includes: performing low-pass filtering on the IQ signal within a first preset time length to obtain the effective signal; performing band-pass filtering on the IQ signal within a first preset duration to obtain the noise signal; and determining a first energy value of the effective signal, and determining a second energy value of the noise signal to obtain an energy intensity value of the IQ signal.
The method can accurately obtain the energy intensity value of the IQ signal.
Further, in a specific embodiment, determining the first energy value of the effective signal and determining the second energy value of the noise signal comprises: acquiring the number of sampling points of the IQ signals in the first preset time length, and recording the number as N, wherein the number of the sampling points is multiple, each sampling point corresponds to one IQ signal, and each IQ signal corresponds to one effective signal and one noise signal; determining a first sum of squares of I and Q components of the effective signal; determining a second sum of squares of the I and Q components of the noise signal; determining an average value of N first square sums to obtain a first energy value; and determining an average value of the N second square sums to obtain a second energy value.
Further, RSSI 1 = is employedA first energy value of the effective signal is determined. Where RSSI 1 is the first energy value of the valid signal,For the number of samples, I 1 is the I component of the effective signal and Q 1 is the Q component of the effective signal.
Further, RSSI 2 = is employedA second energy value of the noise signal is determined. Where RSSI 2 is the second energy value of the noise signal,For the number of samples, I 2 is the I component of the noise signal and Q 2 is the Q component of the noise signal.
Step 103: and determining a signal decibel value according to the energy intensity value.
Note that, the signal decibel value is determined by using the formula 10×log10 (RSSI 1/RSSI2) =db.
Wherein, RSSI 1 is a first energy value of the effective signal, RSSI 2 is a second energy value of the effective signal, and DB represents a signal decibel value.
Step 104: and if the communication terminal is in a power saving state and the signal decibel value is smaller than or equal to a preset threshold value, the power saving state is maintained.
It should be noted that, the preset threshold may be set to-125 dBm. In addition, the preset threshold value can be determined according to the attribute of the mobile terminal, the preset threshold values set by different mobile terminals are different, and the application is not limited to specific numerical values.
Step 105: and if the communication terminal is in an operation state and the signal decibel values in the second preset time period are smaller than or equal to the preset threshold value, controlling the communication terminal to switch from the operation state to the power saving state.
Further, a state where the signal decibel value is less than or equal to the preset threshold represents no signal incoming call, so that the power saving state can be maintained or switched.
In addition, if the running state is switched to the power saving state, the main frequency of the processor is reduced, for example, the running state corresponds to one main frequency, and a main frequency capable of maintaining the received IQ signal can be preset, if the condition of switching to the power saving state is met, the main frequency is directly reduced to the main frequency corresponding to the power saving state, so that in the power saving state, only the main frequency of the received IQ signal is maintained, and further reduction of energy consumption can be ensured.
It should be noted that, the second preset duration is on the order of seconds, for example, 10 seconds to 20 seconds, so that the purpose of this is to reduce the energy consumption as much as possible under the condition of ensuring the user experience. Because if the second preset time period is too short, for example, 1 second, the communication terminal may be caused to frequently perform power saving and switching of the operation state, on one hand, the user experience is bad, and the service life of the communication terminal is not beneficial to prolonging; if the second preset time period is too long, for example, 5 minutes, it is disadvantageous to reduce the power consumption.
In addition, in a specific embodiment, if the communication terminal is in a power saving state and the signal decibel value is greater than the preset threshold, the communication terminal is controlled to switch from the power saving state to the running state.
And if the communication terminal is in an operation state and the signal decibel value is larger than the preset threshold value, maintaining the operation state.
It should be noted that, the db value of the signal being greater than the preset threshold value indicates that there is an incoming signal, so that the signal needs to be maintained or switched to the operation state. Further, the following steps of frame synchronization, decoding and the like are performed.
In addition, the main frequency of the running state is higher than the main frequency of the power saving state, if the running state is switched to the running state from the power saving state, the main frequency of the processor is improved, and as the communication terminal is preset with a main frequency capable of keeping receiving the IQ signal and setting the main frequency required by the corresponding running state, if the condition of switching to the running state is met, the main frequency required by the running state is directly increased, so that the following steps of high operation amounts such as frame synchronization, decoding and the like can be performed after the frequency is increased, that is, the communication terminal can always work at the lower main frequency in the power saving state, and the purpose of reducing the power consumption is achieved.
The energy-saving control system provided by the application is described below, and the energy-saving control system described below and the energy-saving control method described above can be referred to correspondingly.

In a specific embodiment, the power saving state corresponds to a first main frequency, the operating state corresponds to a second main frequency, and the first main frequency is smaller than the second main frequency. In the application, different main frequencies are utilized to distinguish the power saving state and the running state, so that the power saving state works at a relatively low main frequency, the power consumption is reduced, and the standby time of the communication terminal is prolonged.

In a specific embodiment, the first preset duration is on the order of milliseconds. It should be noted that the first preset duration is in the order of milliseconds, and is generally set to 5-10 milliseconds.

In addition, it should be mentioned that 5-10 ms is a preferred duration, and the specific duration may be set according to practical situations, which is not limited by the present application.

Because if the second preset time period is too short, for example, 1 second, the communication terminal may be caused to frequently perform power saving and switching of the operation state, on one hand, the user experience is bad, and the service life of the communication terminal is not beneficial to prolonging; if the second preset time period is too long, for example, 5 minutes, it is disadvantageous to reduce the power consumption.
