Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Some embodiments of the invention are described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.
Fig. 1 is a diagram illustrating an operating environment of a power saving system according to a preferred embodiment of the invention. The power saving system 100 operates in an electronic device 200. The electronic device 200 may be, but is not limited to, a mobile phone, a tablet computer, and a Personal Digital Assistant (PDA). The electronic device 200 includes a battery 201, a processor 203, a storage unit 205, and a Radio Frequency (RF) module 207.
The battery 201 is used for providing power for various functional modules of the electronic device 200, such as the processor 203, the storage unit 205 and the RF module 207. The processor 203 may be a single chip or other micro integrated circuit. The storage unit 205 may be a Memory of the electronic apparatus 200, and may also be a Memory Card that is externally connected to the electronic apparatus 200, such as a Random-Access Memory (RAM) of a Smart Media Card (SM Card), a Secure Digital Card (SD Card), and the like. The RF module 207 is used to establish communication with a base station 300. In this embodiment, when the RF module 207 is turned off, the electronic device 200 enters a flight mode, i.e., the RF module 207 cannot receive the signal from the base station 300, and the network function of the RF module 207 is also turned off. As such, the electronic device 200 cannot access the internet and make or receive calls through the RF module 207. When the RF module 207 is turned off, the network function and the phone function of the electronic device 200 are turned off. When the network function of the RF module 207 is turned off, the electronic device 200 can make or receive a call and cannot access the network, i.e., the hardware portion of the RF module 207 can still operate and still receive the signal from the base station 300. That is, when only the network function of the RF module 207 is turned off, the network function of the electronic device 200 is turned off, but the phone function of the electronic device 200 is still turned on.
The power saving system 100 is configured to detect the signal power received by the RF module 207 from the base station 300, and process the received signal power to execute a corresponding predetermined function, thereby preventing the electronic apparatus 200 from consuming excessive power. The power saving system 100 includes one or more software modules, which are software program segments with specific functions, stored in a readable storage medium or other storage device of the electronic apparatus 200, for example, in the storage unit 205, and executed by the processor 203.
Specifically, please refer to fig. 2, which is a functional block diagram of the power saving system 100 shown in fig. 1. In this embodiment, the power saving system 100 includes a signal obtaining module 11, a comparing module 12, an electric quantity detecting module 13, an executing module 14, and a confirming module 15.
The signal acquiring module 11 is used for acquiring the signal power received by the RF module 207 from the base station 300. For example, in the embodiment, when the RF module 207 of the electronic device 200 establishes a connection with the base station 300, the signal obtaining module 11 obtains a first signal power R received by the RF module 207 from the base station 300 at a first time pointx1And acquires the second signal power R received by the RF module 207 from the base station 300 again at a second time point after a first predetermined time (e.g., 10 seconds) of the first time pointx2。
The comparing module 12 is configured to compare the signal power acquired by the signal acquiring module 11 with the first power value and the second power value pre-stored in the storage unit 205, and output a corresponding control signal according to a comparison result. Specifically, the comparing module 12 respectively compares the first signal power R obtained by the signal obtaining module 11 at a first time pointx1And at a second point in timeSecond signal power Rx2And comparing with the preset first power value. When the first signal power Rx1And a second signal power Rx2When both of the first power values are smaller than the preset first power value, the comparing module 12 sends a first control signal to the executing module 14.
When the comparing module 12 determines the first signal power Rx1And a second signal power Rx2Is not less than the preset first power value, the comparing module 12 further compares the first signal power Rx1And a second signal power Rx2And respectively comparing the power values with the preset second power values. When the first signal power Rx1And a second signal power Rx2When both of the first power value and the second power value are smaller than the preset second power value, the comparison module 12 outputs a detection signal to the electric quantity detection module 13.
The electric quantity detection module 13 is configured to receive the detection signal and obtain an electric quantity value of the battery 201 according to the detection signal. The electric quantity detecting module 13 further compares the acquired electric quantity value of the battery 201 with an electric quantity threshold (e.g. 40% of the total electric quantity of the battery 201) pre-stored in the storage unit 205, and outputs a corresponding control signal to the executing module 14 according to the comparison result. For example, when the electric quantity detection module 13 determines that the acquired electric quantity value of the battery 201 is smaller than a preset electric quantity threshold, the electric quantity detection module 13 outputs the first control signal to the execution module 14. When the electric quantity detection module 13 determines that the acquired electric quantity value of the battery 201 is not less than the preset electric quantity threshold value, a second control signal is output to the execution module 14.
The execution module 14 is configured to receive the first control signal and the second control signal, and execute a corresponding function according to the received first control signal or the received second control signal. For example, when the execution module 14 receives the first control signal, it indicates that the area where the electronic device 200 is located is poor in signal, for example, far away from the base station 300, or the battery power of the electronic device 200 is insufficient. In this way, the execution module 14 notifies the user to turn off or automatically turn off the RF module 207, so that the electronic device 200 enters the flight mode, i.e. the user cannot log on and make or receive a call through the electronic device 200. That is, the network function and the phone function of the electronic device 200 are both turned off. When the execution module 14 receives the second control signal, it indicates that the battery power of the electronic device 200 is sufficient although the received signal is unstable. At this time, the execution module 14 only notifies the user to turn off or automatically turn off the network function of the RF module 207. In this way, the hardware of the RF module 207 still operates effectively, i.e. the RF module 207 can still receive the signal from the base station 300, the user can still make or receive a call through the electronic device 200, and the telephone function of the electronic device 200 is still turned on.
It is understood that, in the present embodiment, the electronic device 200 may notify the user to turn off the RF module 207 or the network function of the RF module 207 by displaying information, sending information, vibrating, ringing, and the like.
It is understood that in other embodiments, after the network function of the RF module 207 is turned off, the RF module 207 can still receive the signal transmitted from the base station 300 because the hardware portion of the RF module 207 is still operating. Therefore, when the network function of the RF module 207 is turned off, the signal obtaining module 11 still obtains the signal power, such as the first signal power R, received by the RF module 207 from the base station 300 at regular timex1And a second signal power Rx2. The comparison module 12 compares the first signal power Rx1And a second signal power Rx2Comparing with the second power value, once the first signal power Rx1And a second signal power Rx2Are greater than the second power value, the comparing module 12 will send a third control signal to the executing module 14. When the first signal power R isx1And a second signal power Rx2When at least one of the values is not greater than the second power value, the comparing module 12 waits for a second preset time (e.g., 30 seconds), and then triggers the confirming module 15 to confirm the valueThe module 15 detects and confirms whether the user has the network function of turning on the RF module 207. When the determination module 15 determines that the user does not turn on the network function of the RF module 207, the determination module 15 sends a feedback signal to the signal acquiring module 11, so that the signal acquiring module 11 continues to acquire the signal power received by the RF module 207 from the base station 300.
It is understood that in other embodiments, after the electronic device 200 enters the flight mode, i.e. turns off the RF module 207, the execution module 14 will turn on the RF module 207 periodically (e.g. after waiting the second time) so that the RF module 207 can receive the signal transmitted from the base station 300. Thus, the signal acquiring module 11 still acquires the signal power, such as the first signal power R, received by the RF module 207 from the base station 300 at regular timex1And a second signal power Rx2. The comparing module 12 further compares the first signal power Rx1And a second signal power Rx2And comparing with the second power value. Once the first signal power Rx1And a second signal power Rx2Are greater than the second power value, the comparing module 12 will send a fourth control signal to the executing module 14. When the first signal power R isx1And a second signal power Rx2When at least one of the power values is not greater than the second power value, the executing module 14 will wait for a second predetermined time again, so that the signal obtaining module 11 continues to obtain the signal power received by the RF module 207 from the base station 300.
It is understood that, in this embodiment, when the execution module 14 receives the third control signal, the execution module 14 notifies the user to turn on or automatically turn on the network function of the RF module 207. When the execution module 14 receives the fourth control signal, the execution module 14 notifies the user to turn on or automatically turn on the RF module 207, that is, notifies the user to turn off or automatically turn off the flight mode of the electronic apparatus 200.
It is understood that, in the present embodiment, the electronic device 200 can still inform the user to turn on the network function of the RF module 207 and/or turn off the flight mode of the electronic device 200 by displaying information, sending information, vibrating, ringing, and the like.
It can be understood that, in the present embodiment, the second preset time is greater than the first preset time. The second power value is greater than the first power value.
It is understood that, in the present embodiment, the executing module 14 may collectively perform the first preset function by automatically starting or notifying the user to start the flight mode of the electronic apparatus 200, automatically turning off or notifying the user to turn off the network function of the electronic apparatus 200. The functions of automatically turning off or informing the user to turn off the flight mode of the electronic device 200, automatically turning on or informing the user to turn on the network of the electronic device 200 are collectively referred to as performing a second preset function. Thus, when the comparing module 12 determines that the first signal power R acquired by the signal acquiring module 11 at the first time point is the first signal power Rx1And a second signal power R obtained at a second time pointx2When both of the first power values are smaller than the preset first power value, the execution module 14 executes a first preset function. When the comparing module 12 determines that the first signal power R acquired by the signal acquiring module 11 at the first time point is not the same as the first signal power R acquired by the signal acquiring module 11 at the first time pointx1And a second signal power R obtained at a second time pointx2When both of the first power value and the second power value are greater than the preset first power value, the execution module 14 executes a first preset function.
Please refer to fig. 3, which is a flowchart illustrating a power saving method according to a preferred embodiment of the present invention, the method includes the following steps:
in step S31, the RF module 207 in the electronic device 200 is connected to the base station 300.
In step S32, the signal obtaining module 11 obtains a first signal power R received by the RF module 207 from the base station 300 at a first time pointx1And acquires the second signal power R received by the RF module 207 from the base station 300 again at a second time point after a first predetermined time (e.g., 10 seconds) of the first time pointx2。
In step S33, the comparing module 12 obtains the signal obtaining module 11Comparing the obtained signal power with a preset first power value to judge the first signal power Rx1And a second signal power Rx2Whether all are less than the preset first power value. If yes, go to step S34. If not, step S35 is executed.
In step S34, the comparing module 12 sends a first control signal to the executing module 14.
In step S35, the comparing module 12 continues to obtain the first signal power R obtained by the signal obtaining module 11x1And a second signal power Rx2Comparing with a preset second power value to judge the first signal power Rx1And a second signal power Rx2Whether all are less than the preset second power value. If yes, a detection signal is output to the power detection module 13, and step S36 is executed. If not, the flow ends.
In step S36, the electric quantity detection module 13 receives the detection signal and obtains the electric quantity value of the battery 201 according to the detection signal.
In step S37, the electric quantity detection module 13 further compares the acquired electric quantity value of the battery 201 with a preset electric quantity threshold (e.g., 40% of the total electric quantity of the battery 201) to determine whether the acquired electric quantity value of the battery 201 is smaller than the preset electric quantity threshold, and if so, executes step S34. If not, step S38 is executed.
In step S38, the comparing module 12 sends a second control signal to the executing module 14.
In step S39, when the executing module 14 receives the first control signal, it indicates that the area where the electronic device 200 is located is poor, for example, far away from the base station 300, or the battery power of the electronic device 200 is insufficient. In this way, the execution module 14 notifies the user to turn off or automatically turn off the RF module 207, so that the electronic device 200 enters the flight mode, i.e. the user cannot log on and make or receive a call through the electronic device 200.
In step S310, when the execution module 14 receives the second control signal, it indicates that the battery power of the electronic device 200 is sufficient although the received signal is unstable. At this time, the execution module 14 only notifies the user to turn off or automatically turn off the network function of the RF module 207. At this time, the hardware of the RF module 207 still operates effectively, i.e. the RF module 207 can still receive the signal from the base station 300, and the user can still make or receive a call through the electronic device 200.
Referring to fig. 4, when the network function of the electronic device 200 is turned off, the power saving method further includes the following steps:
in step S41, the signal obtaining module 11 obtains a first signal power R received by the RF module 207 from the base station 300 at a first time pointx1And acquires the second signal power R received by the RF module 207 from the base station 300 again at a second time point after a first predetermined time (e.g., 10 seconds) of the first time pointx2。
In step S42, the comparing module 12 compares the signal power obtained by the signal obtaining module 11 with a preset second power value to determine the first signal power Rx1And a second signal power Rx2Whether the power values are all larger than the preset second power value. If yes, go to step S43. If not, step S44 is executed.
In step S43, the comparing module 12 sends a third control signal to the executing module 14.
In step S44, after waiting for a second preset time (e.g. 30 seconds), the comparing module 12 triggers the confirming module 15, so that the confirming module 15 detects or confirms whether the user has turned on the network function of the RF module 207. If yes, the process ends. If not, the process returns to step S41, so that the signal acquiring module 11 continues to acquire the signal power received by the RF module 207 from the base station 300.
In step S45, the execution module 14 receives the third control signal and notifies the user to start or automatically start the network function of the RF module 207.
Referring to fig. 5, when the RF module 207 of the electronic device 200 is turned off, i.e. the flight mode is turned on, the power saving method further includes the following steps:
and step S51, waiting for the second preset time.
In step S52, the RF module 207 is turned on temporarily so that the RF module 207 can receive the signal from the base station 300. The signal acquiring module 11 acquires a first signal power R received by the RF module 207 from the base station 300 at a first time pointx1And acquires the second signal power R received by the RF module 207 from the base station 300 again at a second time point after a first predetermined time (e.g., 10 seconds) of the first time pointx2. The temporary turning-on refers to turning on the RF module 207 briefly, for example, when obtaining the first signal power Rx1Before turning on the RF module 207 and obtaining the second signal power Rx2Thereafter, the RF module 207 is turned off or the first signal power R is obtainedx1Before turning on the RF module 207 and obtaining the first signal power Rx1Then the RF module 207 is turned off and then the second signal power R is obtainedx2Before turning on the RF module 207 and obtaining the second signal power Rx2The RF module 207 is then turned off.
In step S53, the comparing module 12 compares the signal power obtained by the signal obtaining module 11 with a preset second power value to determine the first signal power Rx1And a second signal power Rx2Whether the power values are all larger than the preset second power value. If yes, go to step S54. If not, the process returns to step S51.
In step S54, the comparing module 12 sends a fourth control signal to the executing module 14.
In step S55, the execution module 14 receives the fourth control signal and notifies the user to turn on or automatically turn on the RF module 207 to turn on the network function and the phone function of the electronic device 200, i.e., turn off the flight mode of the electronic device 200.
The power saving system and the method respectively compare the power values of the two time points with the preset first power value and the second power value, and execute the corresponding first preset function or the second preset function according to the comparison result, so that when the electronic device 200 is in an area with poor signals or the electric quantity is insufficient, the network function of the electronic device 200 is closed or the flying mode is directly started, and the purpose of effectively saving power is achieved.
