Part related to the present invention is illustrate only, details are as follows：
In step sl, judge whether remote control is in initial power-on state, be, then execution step S4, no, then perform step
Rapid S2.
In step s 2, judge whether the button of remote control is pressed, be, then execution step S4, no, then perform step
S3。
In step s3, judge whether the button of remote control is not pressed within a preset time interval, be then to perform step
S4, it is no, then perform step S7.
In step s 4, according to default modulus sampling resolution sampled reference in the state of remote control does not send control signal
Voltage simultaneously generates corresponding first numerical reference magnitude of voltage, and according to default modulus sampling resolution, reference voltage and the first numeral
Reference voltage value obtains the first battery voltage value.
Wherein, in step S4 basis is preset modulus sampling resolution, reference voltage and the first numerical reference magnitude of voltage and obtained
The step of first battery voltage value is specially：
The first battery voltage value is calculated according to following formula：
Wherein, V1 is the magnitude of voltage of voltage on the basis of the first battery voltage value, V0, and X is default modulus sampling resolution（Can be with

Sample voltage value is as the second numerical reference magnitude of voltage, and according to default modulus sampling resolution, reference voltage and the second digital base
Quasi- magnitude of voltage obtains the second battery voltage value.
It should be noted that because remote control only can just send control signal when button is pressed, so in remote control
In initial power-on state or standby（It is pressed within a preset time interval without button without sending control signal）When, herein
It is actually that the control signal for making remote control work in simulation sends state that described remote control, which is in control signal and sends state,
's.
Obtained in addition, the basis in step S5 presets modulus sampling resolution, reference voltage and the second numerical reference magnitude of voltage
The step of second battery voltage value is specially：

Wherein, V2 is the magnitude of voltage of voltage on the basis of the second battery voltage value, V0, and X is default modulus sampling resolution（Can be with
For 8,10 or 12 etc.）, AD2 is the second numerical reference magnitude of voltage.
In step s 6, battery level information is obtained according to the first battery voltage value and the second battery voltage value, and driven
Battery level information described in remote controller displays.
Wherein, the step that battery level information is obtained according to the first battery voltage value and the second battery voltage value in step S6
It is rapid to be specially：
Battery is obtained in default collection voltages-electricity relation according to the first battery voltage value and the second battery voltage value
Information about power.
For example, default collection voltages-electricity relation is as shown in the table：
N lattice in upper table（N is equal to 0,1,2,3 or 4）As battery level information, after battery level information is got again
Driving remote controller displays module shows the battery level information, as shown in Fig. 2 since battery level information is 4 lattice, often reducing
1 lattice then represent battery electric quantity reduce 25%, so it is possible thereby to allow user be clear from understand battery electric quantity consumption situation.
In an alternative embodiment of the invention, being obtained according to the first battery voltage value and the second battery voltage value in step S6
The step of battery level information, may further be embodied as：
Comprehensive battery voltage value is calculated according to following formula：
V=V2·P+V1·(1-P)
Wherein, V is comprehensive battery voltage value, and P is default COMPREHENSIVE CALCULATING coefficient, and its span is [0.2,0.8],
This is preferably that 0.5, V1 is the first battery voltage value, and V2 is the second battery voltage value.
Battery level information is obtained according still further to following formula：
Wherein, V3 is the voltage of the new battery in full power state, and its theoretical voltage value is 3.0V, but due to different electricity
The battery that pond manufacturer is produced can slightly have difference, so V3 span can be chosen to be [2.9V, 3.1V], herein preferably
For 3.0V；V4 is magnitude of voltage when battery power consumption can not extremely be used, also due to the difference of cell production companies, so V4
Span can be chosen to be [1.8V, 2.4V], preferably 2.0V herein；n（N is equal to 0,1,2,3 or 4）As battery electric quantity is believed
Breath, drives remote controller displays module to show the battery level information again after battery level information is got, as shown in Fig. 2 from
Battery level information is that 4 lattice start, and often reduces by 1 lattice and then represents that battery electric quantity reduces 25%, so it is possible thereby to allowing user will be apparent that
Ground understands the consumption situation of battery electric quantity.
In the step s 7, electric power detection process is terminated.
In embodiments of the present invention, it is standby in remote control（It is pressed within a preset time interval without button without sending
Control signal）When, the operating current of remote control is typically smaller than 30 μ A, and the electric quantity consumption of battery is more slow, in order to reduce electricity
Consumption, it may not be necessary to frequently detect electricity, so can be determined by step S3 remote control in longer time whether without by
Key is pressed, if it is, determining remote control standby a very long time, and entering by performing step S7 to terminate electric power detection
Journey, so prefixed time interval is more suitable in units of hour, and prefixed time interval is greater than or equal to 10 hours, excellent
Elect as 24 hours.
The remote control detection method of quantity of electricity provided for the embodiment of the present invention is, it is necessary to which explanation, step S4 is actually
Be remote control initial power-on or it is standby when reference voltage is sampled, step S5 be then remote control in control signal send out
Send state（State is sent including true and simulation control signal）Under reference voltage is sampled, although both of which be use
What default modulus sampling resolution was sampled, but because voltage sample can be influenceed by cell voltage, so above-mentioned first
Battery voltage value and the second battery voltage value are different, thus just can combine the first battery voltage value and the second cell voltage
Value is to accurately determine battery level information, so that battery level information of the remote control shown by user is more close to electricity
The change of cell voltage, can thus avoid the occurrence of battery level information and show normal and remote control because cell voltage is relatively low and multiple
Position and make user can not understand grasp remote control battery electric quantity situation the problem of, while it also avoid user sends throwing to manufacturer
Tell.
