Detailed Description
The core of the invention is to provide a method for detecting the residual electric quantity of the remote controller and sending a prompt to the remote controller when the residual electric quantity in the remote controller is insufficient so as to improve the use convenience of the remote controller.
In order that those skilled in the art will better understand the disclosure, the invention will be described in further detail with reference to the accompanying drawings and specific embodiments. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the 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.
As shown in fig. 1, fig. 1 is a schematic structural diagram of a remote controller low power reminder provided in an embodiment of the present application, where the device may include:
an SOC module 10, a low battery detection circuit 20, a power supply module 50, and an alarm module 40;
the power module 50 is configured to output a power supply voltage;
the low power detection circuit 20 is configured to detect a remaining power of the power module 50, and output an electric signal indicating that the power is insufficient when the remaining power of the power module 50 is less than a predetermined power;
the SOC module 10 is configured to control the alarm module 40 to alarm when receiving the electric signal of low power.
It should be noted that the SOC module 10 in this embodiment may be a main control chip module for the normal operation of the remote controller, and certainly, the SOC module 10 is not excluded from the application as a control chip specially configured for realizing low power reminding of the remote controller in the remote controller.
The power module 50 in this embodiment is specifically a module for supplying power to each electronic circuit device in the remote controller, and may include a detachable and replaceable battery, or a rechargeable battery capable of being charged, which is not limited in this application. Generally, the remaining capacity of the power module 50 is positively correlated with the magnitude of the voltage signal output by the output terminal thereof, and when the remaining capacity of the power module 50 is insufficient, the magnitude of the output power supply voltage is reduced, and the smaller the remaining capacity is, the smaller the output power supply voltage is. Therefore, the low power detection circuit 20 in this embodiment can detect the magnitude of the power supply voltage at the output terminal of the power module 50 based on this, so as to detect the remaining power of the power module 50. It should be understood that, in practical applications, other technical solutions that implement the detection of the remaining power of the power module 50 in a manner similar to the detection of the output current of the power module 50, or the detection of the power consumption of the power module themselves, etc., are not excluded, and this is not illustrated in this embodiment.
The alarm module 40 in this embodiment is mainly used to send an alarm prompt to a user when the remaining power of the power module 50 is insufficient, so as to prompt the user to replace the battery in the power module 50 or charge the storage battery in the power module 50 in time. Alarm module 40 in this embodiment can realize the warning suggestion through pronunciation equipment such as bee calling organ, also can arouse the purpose that the user noticed in order to reach the warning through the light scintillation of LED lamp, to this, does not do in this application in detail and give unnecessary detail.
To sum up, the low-power reminding device of remote controller in this application can carry out the residual capacity detection to the power module in the remote controller at the remote controller during operation to when detecting and confirming that power module residual capacity is not enough, send the warning suggestion to the user through alarm module, in order to remind the user in time to carry out battery replacement or charge to power module, can avoid to a certain extent because the electric quantity is not enough to lead to the unavailable problem of remote controller, promote the user and use the use of remote controller and experience.
Based on the foregoing embodiments, in an optional embodiment of the present application, the low battery detection circuit may include:
the low battery detection circuit 20 includes a first comparator and a first voltage dividing resistor;
the positive phase input end of the first comparator is connected with the reference voltage end through a first voltage dividing resistor; the inverting input end of the first comparator is connected with the output end of the power supply module; the output of the first comparator is connected to the SOC-module 10.
It should be noted that the output voltage of the reference voltage terminal should be smaller than the output voltage of the power module 50 under the condition of sufficient power. The reference voltage may be obtained by performing voltage conversion on the output voltage of the power module 50, or may be provided by another power module other than the power module 50.
According to the basic operation principle of the comparator, when the voltage signal at the non-inverting input terminal of the first comparator is greater than the voltage signal at the inverting input terminal thereof, the output terminal thereof outputs a high level signal, and the output terminal of the first comparator is equivalent to the output terminal of the low battery detection circuit 20 connected to the SOC module 10. Therefore, in the present application, the non-inverting input terminal of the first comparator is connected to the reference voltage terminal through the first voltage dividing resistor, and the input voltage to the non-inverting input terminal of the first comparator is further reduced by the voltage dividing function of the first voltage dividing resistor.
On this basis, the inverting input terminal of the first comparator is connected to the output terminal voltage of the power module 50. Obviously, when the power of the power module 50 is sufficient, the voltage at the inverting input terminal of the first comparator is greater than the voltage at the non-inverting input terminal, and the output terminal of the first comparator outputs a low level signal; when the output voltage is reduced to be less than the voltage at the non-inverting input terminal of the first comparator due to insufficient power of the power module 50, the output terminal of the first comparator outputs a high level signal, so that when the SOC module 10 receives the high level signal output by the output terminal of the first comparator, it can be determined that the remaining power of the power module 50 is insufficient, and the alarm module 40 needs to be controlled to send an alarm.
In addition, the size of the first voltage-dividing resistor between the reference voltage terminal and the non-inverting input terminal of the first comparator may be set according to a set remaining power alarm threshold of the power module 50, and when the resistance value of the first voltage-dividing resistor is larger, the voltage division is larger, and the remaining power alarm threshold of the corresponding power module 50 is smaller.
Further, it is considered that the alarm is only sent out when the remaining power of the power module 50 is very low or even unavailable, so that the time for replacing or charging the battery reserved for the user is relatively short, and the inconvenience of using the remote controller by the user is also brought.
To this end, the low battery detection circuit in another optional embodiment of the present application may further include:
the low battery detection circuit 20 further includes a second comparator and a second voltage dividing resistor;
the positive input end of the second comparator is connected with the first end of the second voltage-dividing resistor; the second end of the second voltage-dividing resistor is connected with the reference voltage end through the first voltage-dividing resistor; and the inverting input end of the second comparator is connected with the output end of the power supply module.
Similar to the operation principle of the first comparator, the inverting input terminal of the second comparator in this embodiment is connected to the output terminal of the power supply module 50. In contrast, in the present embodiment, the positive input terminal of the second comparator is connected to the reference voltage terminal through the first voltage-dividing resistor and the second voltage-dividing resistor, so that the voltage signal input from the reference voltage terminal to the positive input terminal of the second comparator is a voltage signal obtained by the common voltage-dividing action of the first voltage-dividing resistor and the second voltage-dividing resistor, that is, the voltage signal input from the positive input terminal of the second comparator is smaller than the voltage signal input from the positive input terminal of the first comparator, and when the voltage at the output terminal of the power module with the negative input terminal of the second comparator being connected is reduced to be smaller, the output terminal of the second comparator outputs a high-level signal.
Therefore, when the remaining power of the power module 50 is insufficient and the voltage at the output end is low, the first comparator can output a high level signal to the SOC module 10, the SOC module 10 can control the alarm module 40 to output a first level alarm, and when the remaining power of the power module 50 is further reduced to be seriously insufficient and the voltage signal output by the power module is smaller, the second comparator also outputs a high level signal to the SOC module 10 and the SOC module 10 controls the alarm module to output a second level alarm, so that two-level alarm under two conditions of insufficient power and serious insufficient power of the power module 50 is realized.
The alarm voltage threshold corresponding to the two-stage alarm can be determined by setting the resistance values of the first divider resistor and the second divider resistor. For example, the first voltage-dividing resistor and the second voltage-dividing resistor can be set to be in proper sizes, so that when the voltage output by the output end of the power supply module is 30% of the rated voltage of the power supply module, the output end of the first comparator outputs a high-level signal; when the output voltage of the output terminal of the power module 50 is the lowest voltage that can be output by the power module 50, both the first comparator and the second comparator output high level signals.
To further explain the structure of the low power detection circuit, referring to fig. 2, fig. 2 is a specific embodiment of the low power detection circuit of the present application.
Fig. 2 is a schematic structural diagram of a low power detection circuit according to an embodiment of the present disclosure, referring to fig. 2, in which a non-inverting input terminal of a first comparator U1 in fig. 2 is connected to a first terminal of a first voltage-dividing resistor R21, and a second terminal of the first voltage-dividing resistor R21 is connected to a reference voltage terminal Vref; the non-inverting input end of the second comparator U2 is connected to the first end of the second voltage-dividing resistor R22, and the second end of the second voltage-dividing resistor R22 is connected to the first end of the first voltage-dividing resistor R21; meanwhile, the non-inverting input terminal of the second comparator U2 is also connected to the first terminal of the third voltage-dividing resistor R23, and the second terminal of the third voltage-dividing resistor R23 is grounded. The inverting inputs of the first comparator U1 and the second comparator U2 are connected to the output VDD of the power module 50. In fig. 2, the voltages at the node V1 and the node V2 are the voltages at the non-inverting input terminal of the first comparator U1 and the non-inverting input terminal of the second comparator U2, respectively, and it is obvious that the voltage at the node V1 is higher than the voltage at the node V2, so that when the first comparator U1 and the second comparator U2 output high level signals, the output terminal of the power module 50 is required to input a lower voltage signal to the inverting input terminals of the two comparators.
The second end of the first voltage-dividing resistor R21 and the second end of the third voltage-dividing resistor R23 are also connected through a first capacitor C21, and the inverting input ends of the first comparator U1 and the second comparator U2 are both grounded through a second capacitor C22; and the non-inverting input of the first comparator U1 is grounded through a third capacitor C23, while the non-inverting input of the second comparator U2 is grounded through a fourth capacitor C24; in addition, the power input terminals of the first comparator U1 and the second comparator U2 are both connected to a dc voltage terminal VCC, and the voltage of the dc voltage terminal VCC may be obtained by performing voltage conversion on the voltage output by the power module 50, or may be determined by using other dc power supplies.
Further, the first output terminal Vout1 of the first comparator U1 is grounded through the fourth voltage-dividing resistor R24, and the second output terminal Vout2 of the second comparator U2 is grounded through the fifth voltage-dividing resistor R25.
It should be noted that, in the low power detection circuit shown in fig. 2, the first capacitor C21, the second capacitor C22, the third capacitor C23, the fourth capacitor C24, the fourth voltage-dividing resistor R24, and the fifth voltage-dividing resistor R25 are all set to ensure the stability of the operation of the whole circuit, and there is no substantial influence on how to implement the remaining power of the power module 50 and how to output the detected remaining power to the SOC module 10, so details of this embodiment are not described herein.
As mentioned above, during the normal operation of the low battery detection circuit 20, a stable dc voltage needs to be provided through the dc voltage terminal VCC and the reference voltage terminal, and for this reason, in an optional embodiment of the present application, a boost chip 30 connected to the output terminal of the power module 50 may be further included. The boost chip 30 may be an XC9140a331MR chip;
a first input end of the boost chip 30 is connected with an enable output end of the SOC module 10; the second input end of the boost chip 30 is connected with the output end of the power module 50; the output end of the boost chip 30 is a direct-current voltage end; the direct current output end of the direct current power supply is connected with the direct current output end of the direct current power supply, and the other end of the direct current power supply is used as a reference voltage end to output reference voltage.
Fig. 3 is a schematic circuit structure diagram of the boost chip according to the embodiment of the present application, and referring to fig. 3, a first input terminal, that is, a CE pin, of the boost chip 30 is connected to an enable output terminal Boot _ EN of the SOC module 10.
It should be noted that, for the remote controller, the remote controller is kept in a sleep state in an idle state (a state unused by a user), the power consumption of the remote controller in the sleep state is extremely low, and it is not necessary to detect the remaining power of the power module 50 in real time, and in the using process of the user, it is only necessary to detect the power of the power module 50 when the user starts to use the remote controller, and it is not necessary to continuously detect the power of the power module 50, so that on one hand, the uncomfortable use experience brought by frequent power alarm is avoided when the power is saved and on the other hand, the user is not required to be frequently used.
Therefore, in the present embodiment, whether the low power detection of the power module 50 is performed or not can be realized by controlling whether the boost chip 30 works or not; specifically, whether the boost chip 30 works or not can be controlled through the enable output terminal Boot _ EN of the SOC module 10 to the boost chip 30 or not; when the boost chip 30 does not operate, it is obviously impossible to output the dc voltage through the dc output terminal and output the reference voltage through the reference voltage terminal, so the low power detection circuit 20 also handles the non-operating state, thereby suspending the low power detection and alarming.
In addition, in order to ensure the stability of the boost chip 30 during operation, a first resistance element R31 may be connected to the first input terminal of the boost chip 30. Secondly, the second input terminal of the boost chip 30 is also the Vbat pin in fig. 3, and the Vbat pin is connected to the output terminal VDD of the power module 50; the LX pin of the boost chip 30 is also connected to the output terminal VDD of the power module 50 through the inductor L; in order to ensure the stability of the performance of the boost chip 30 during the operation, a fifth capacitor C31 is connected in parallel between the output terminal VDD of the power module 50 and the inductance element L; the first end of the inductance element L is connected to the LX pin of the boost chip 30; the second terminal of the inductor L is connected to the output terminal VDD of the power module 50 and the first terminal of the fifth capacitor C31, and the second terminal of the fifth capacitor C31 is grounded; the first end of the inductive element L and the Vbat pin are further connected with a sixth capacitor C32, the first end of the sixth capacitor C32 is connected with the second end of the inductive element L and the Vbat pin, and the second end of the sixth capacitor C32 is grounded. The output terminal of the boost chip 30, i.e., the pin Vout, can be used as the dc voltage terminal VCC; in order to obtain the reference voltage outputted from the reference voltage terminal Vref in the low battery level detection circuit 20, in this embodiment, a second resistor element R32 is further connected to the Vout pin of the boost chip, the first terminal of the second resistor element R32 is connected to the Vout pin, and the voltage of the second terminal of the second resistor element R32 is the reference voltage smaller than the voltage of the dc voltage terminal VCC by the voltage division function of the second resistor element R32. In order to ensure the stability of the circuit, the pin Vout is also grounded through a seventh capacitor C33; and the second terminal of the second resistive element R32 is also grounded through the third resistive element R33.
As mentioned above, the alarm module 40 in the present application may include a flashing light, or a voice alarm, etc., and in an alternative embodiment of the present application, the alarm module includes:
the circuit comprises a first resistor, a second resistor, a third resistor, a photodiode and a triode;
the first end of the first resistor is connected with the output end of the SOC module 10; the second end of the first resistor is connected with the base electrode of the triode; the first end and the second end of the second resistor are respectively connected with the base electrode and the emitting electrode of the triode; the emitting electrode of the triode is connected with the output end of the power supply module through a third resistor;
the negative electrode of the photodiode is connected with the collector of the triode; the positive pole of the photodiode is connected with the direct-current voltage end.
The SOC module 10 is configured to output a pulse signal to the first end of the first resistor when receiving the electric signal of insufficient electric quantity, so as to control the photodiode to flash.
Referring to fig. 4, the SOC module 10 is connected to the base of a transistor Q1 through a first resistor R41; the base electrode and the emitting electrode of the triode Q1 are connected through a second resistor R42; and the collector of the transistor Q1 is connected to the dc voltage terminal VCC through the third resistor R43 and the photodiode LED.
When the SOC module outputs a pulse signal to the first end of the first resistor R41, the emitter and the collector of the transistor Q1 are periodically turned on and off, and for the photodiode LED, the LED lamp is equivalent to an LED lamp, that is, the photodiode LED is periodically turned on in the forward direction and turned off in the reverse direction.
As mentioned above, the low power detection circuit 20 can implement two-stage low power detection alarm, and when the power of the power module 50 is insufficient and the power is seriously insufficient, the SOC module 10 can control the photodiodes LED to alarm according to different frequency flashes. For example, when the output terminal of the first comparator U1 outputs a high level signal and the output terminal of the second comparator U2 outputs a low level signal, the SOC module 10 may output a pulse signal of a first frequency to the first terminal of the first resistor R41 in the alarm module 40; when the output terminals of the first comparator U1 and the second comparator U2 both output high level signals, the SOC module 10 may output a pulse signal of a second frequency to the first terminal of the first resistor R41; the first frequency is smaller than the second frequency, so that when the remaining power of the power module 50 is insufficient, the photodiode LED flashes at the first frequency, and when the power of the power module 50 is seriously insufficient, the photodiode LED flashes at the second frequency, which is a higher frequency, so that a user can specifically distinguish the severity of power shortage.
In addition to controlling the flashing frequency of the photodiode LED, the PWM signal when the photodiode LED is lit can be controlled to control the brightness of the photodiode LED. As shown in fig. 5, fig. 5 is a schematic diagram of pulse signals for controlling the operation of the photodiode according to the embodiment of the present application.
The period T1 in fig. 5 corresponds to the blinking period of the photodiode LED; in a period T1, the photodiode LED is turned on by a PWM signal with a period T2 in a period T, and the photodiode LED is in an off state in a period other than the period T in the period T1, so that the light of the photodiode LED flickers; wherein, the larger the duty ratio of the PWM signal in the period T2, the higher the brightness of the photodiode LED; that is, the size of the period T1 determines the flashing frequency of the photodiode LED, and the PWM duty cycle determines the brightness of the photodiode LED.
Further, in order to ensure that the alarm module 40 can remind the user of low power, the alarm module 40 may further include a voice alarm module, and when the low power detection circuit 20 detects that the power of the power supply module is insufficient, the voice alarm module may send a voice alarm to the user.
Referring to fig. 6, fig. 6 is a schematic circuit structure diagram of a voice alarm module according to an embodiment of the present application, where the circuit structure of the voice alarm module is similar to that of the light flashing alarm module in fig. 4, except that a diode D and a buzzer BZ connected in parallel are disposed at a position corresponding to the position where the photodiode LED in fig. 4 is disposed in fig. 6. The circuit operation principle is understood by combining the circuit operation principle in fig. 4 and the common sense of circuit operation, and detailed description thereof is omitted in this application.
Certainly, in practical application, the voice alarm module is not necessarily a buzzer, and may also be a speaker for playing voice prompts like "power shortage", "power shortage seriously", and the like, and therefore, no specific limitation is made in the present application.
In addition, the present application does not exclude the embodiment in which the alarm module simultaneously performs the alarm by using the flashing of the photodiode LED and the alarm by the voice of the voice alarm module. When power module 50's residual capacity is not enough, can start light scintillation warning and audio alert simultaneously, even, adopt light scintillation warning when the electric quantity is not enough, and adopt audio alert when the electric quantity is serious not enough, perhaps all adopt light scintillation warning when detecting the electric quantity not enough in the time at every turn, and the user does not change the battery or when not charging for a long time, then starts audio alert etc. is the optional embodiment of this application, no longer enumerates one by one in this application.
Based on the above discussion, when detecting the remaining power of the power module in the remote controller, if the remaining power is insufficient, it indicates that the remaining power can support the remote controller for a short time, and in order to save power and maintain the remote controller to be able to operate for a longer time, when detecting and determining that the power of the power module is insufficient, the functions that can be turned off in the remote controller can be turned off as much as possible, and only the basic operation functions are maintained.
For example, for a remote controller capable of implementing voice instruction input, the MIC module 60, i.e. a voice pickup module, is generally configured inside the remote controller, and is used for collecting voice information of a user, when the remaining power of the power module 50 is insufficient, the SOC module 10 may turn off the function of the MIC module 60, and only allow the user to operate keys on the remote controller to implement use of the remote controller.
Similarly, for some remote controllers with a display screen, turning off the backlight of the display screen, even directly turning off the function of the display screen, or shortening the screen-on time of the display screen after receiving no control instruction from the user, and the like may also be considered.
Based on any of the above embodiments, the present application further provides a remote controller low power reminding method applied to any of the above embodiments, and referring to fig. 7, the method may include:
s11: and collecting electric quantity detection signals of a power supply module in the remote controller.
As described above, the remote controller is generally in a sleep state when the user does not use the remote controller, and the power consumption in the sleep state is very low, so that in the sleep state, real-time detection of the residual power of the power module is not necessary, and when the user does not use the remote controller, the remote controller frequently detects and alarms when the power of the remote controller is insufficient, and the remote controller can also affect the user to have a rest to a certain extent, thereby bringing a bad user experience to the user.
Therefore, in the actual use process, when a user operates a key on the remote controller or inputs a control instruction through the voice pickup module (which can be an MIC module), the remote controller is awakened and then detects the residual electric quantity of the power supply module in the remote controller to obtain an electric quantity detection signal, so that the user can be prevented from being disturbed to a certain extent to have a rest, and the problem of further energy consumption caused by the fact that the residual electric quantity of the power supply module is detected and collected can be avoided to a certain extent.
S12: when the electric quantity detection signal indicates that the residual electric quantity of the power supply module is less than the set electric quantity, an alarm instruction is output.
Based on the above embodiments, the detection alarm of the remaining power of the power module in this embodiment can be divided into two levels of alarms, and the following description will take the remaining power of the power module as an example of insufficient power and serious insufficient power. It can be understood that the power shortage and the power serious shortage can be set according to the actual working condition of the remote controller, the power shortage state can be set when the remaining power of the power module is less than 30% of the total power, the power serious shortage state can be set when the remaining power of the power module is less than 10% of the total power, and the power serious shortage state can be defined according to other modes.
In order to facilitate the user to distinguish whether the alarm sent by the alarm device corresponds to the state of insufficient power or the state of serious insufficient power, in an optional embodiment of the present application, the method may include:
when the electric quantity detection signal indicates that the residual electric quantity of the power supply module is smaller than a first set electric quantity and larger than a second set electric quantity, outputting a first alarm instruction to control the LED lamp to flicker according to first brightness;
when the electric quantity detection signal indicates that the residual electric quantity of the power supply module is smaller than a second set electric quantity, outputting a second alarm instruction to control the LED lamp to flash according to second brightness; wherein the first brightness is less than the second brightness.
It should be noted that, the alarm module in this embodiment is described by taking an LED lamp as an example of an alarm, and for the LED lamp, a signal for driving the LED lamp to operate is generally a PWM signal, where the larger the duty ratio of the PWM signal is, the higher the brightness of the LED lamp is, and conversely, the smaller the duty ratio of the PWM signal is, the lower the brightness of the LED lamp is. In order to facilitate the distinguishing of insufficient electric quantity and serious insufficient electric quantity by a user, the LED lamp can be driven to work by PWM signals with different duty ratios, and the LED lamp can be lightened according to different brightness when the electric quantity of the power supply module is insufficient and the electric quantity is seriously insufficient.
Of course, it can be understood that, in the practical application process, the LED lamp may also be caused to blink according to different frequencies according to the frequencies for controlling the LED lamp to be turned on and off, so as to distinguish the insufficient power from the serious power, and the embodiment is not limited in detail.
In addition, when the electric quantity of the remote controller is considered to be insufficient, if the user continuously gives an alarm when using the remote controller, the user can be provided with bad use experience. To this end, in an optional embodiment of the present application, the method may further include:
when the duration of the continuous alarm of the alarm module reaches the set duration, the alarm module is controlled to stop alarming.
Taking the LED lamp as an alarm module as an example, the duration of the continuous alarm can be determined according to the duration of the PWM signal for driving the LED lamp to work, and when the duration of the continuous alarm reaches the set duration, the PWM signal for driving the LED lamp to work is stopped being output, so that the control of stopping the alarm is realized. Of course, if the alarm duration does not reach the alarm duration, and the user inputs the instruction of stopping the alarm by operating the remote controller, the alarm can also be stopped immediately.
Further, as mentioned above, in the present application, the power module may be detected each time the remote controller is awakened to start up, and the alarm may be given when the electric quantity is insufficient, but it is considered that when the user uses various electrical and electronic devices, for example, when the user is watching tv, and when the user turns on the tv through remote control of the tv, the remote controller may be started up for the first time, and the alarm may be given when the electric quantity of the remote controller is insufficient; when a user finds a television program to be watched, the user can stop using the remote controller temporarily, the remote controller enters a sleep mode at the moment, when the user needs to replace the television program, the user can wake up and start the remote controller for the second time, the power supply module in the remote controller is still in a state of insufficient electric quantity at the moment, the alarm is sent out again, and the rest is done in the same way, the user needs to give an alarm once when starting the remote controller every time, and obviously, the user can be also provided with bad use experience due to frequent alarm. That is to say, the electric quantity detection and the warning when the electric quantity is not enough can all be carried out in every remote controller start-up, can lead to the user to have the frequent warning of sending out when the interrupted frequent use remote controller, causes the problem that the user experiences poorly.
To this end, in an optional embodiment of the present application, may include:
when the electric quantity detection signal indicates that the residual electric quantity of the power supply module is less than the set electric quantity and the times of receiving the remote controller starting instruction are accumulated to the preset times, the alarm instruction is output.
Taking the preset number of times as 10 times as an example, when the electric quantity of the remote controller is determined to be insufficient through first detection, the alarm is not sent out, if the remote controller is awakened and started from the next 2 nd time to the 10 th time, the measured electric quantity of the power supply module in the remote controller is insufficient every time, the alarm is sent out when the remote controller is awakened and started from the 10 th time, meanwhile, the accumulated number of times of detecting the electric quantity insufficiency is reset, and accumulated counting is carried out again when the electric quantity insufficiency is detected again next time, so that the purpose of reducing the alarm frequency is achieved, and the user experience is improved.
Certainly, the purpose of reasonably prompting the user to replace or charge the battery is obviously not achieved in consideration of the fact that the insufficient electric quantity of the power supply module in the remote controller only prompts the user to prepare to replace or charge the battery, and when the electric quantity is seriously insufficient, the battery needs to be replaced or charged; for this reason, in another alternative embodiment of the present application, different accumulation times for detection may be set for the power shortage and the power serious shortage, and the accumulation times may be set to be smaller for the power serious shortage.
In addition, in order to further reduce the electric quantity consumed for detecting the residual electric quantity of the power module, the residual electric quantity can be detected and alarmed in sequence only when the remote controller is awakened and started for preset times.
It should be noted that, to solve the problem that the user experiences poor user experience due to frequent alarm when the user intermittently uses the remote controller frequently because the remote controller is started to detect the electric quantity and alarm when the electric quantity is insufficient every time, the implementation is not limited to setting a fixed accumulated number of times. For example, it is also possible to perform the detection and alarm of the remaining amount of power only when the remote controller is activated at a fixed point of time every day; or the detection and the alarm of the residual electric quantity are carried out when the remote controller is awakened and started every two days or three days, and the like. Namely, the time interval of the residual capacity detection and the alarm is set; the setting of the interval duration can be set reasonably according to the electricity consumption speed of the remote controller, which is not described in detail in this application.

Furthermore, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include elements inherent in the list.
