In step S2, judge whether the button of telepilot is pressed, be, perform step S4, no, perform step S3.
In step S3, judge whether the button of telepilot is not pressed within a preset time interval, be, perform step S4, no, perform step S7.
In step S4, under the state not transmitting control signal at telepilot, according to default modulus sampling resolution sampling reference voltage and generate corresponding the first numerical reference magnitude of voltage, and obtain the first battery voltage value according to default modulus sampling resolution, reference voltage and the first numerical reference magnitude of voltage.
Wherein, the step of obtaining the first battery voltage value according to default modulus sampling resolution, reference voltage and the first numerical reference magnitude of voltage in step S4 is specially:
According to following formula, calculate the first battery voltage value:
Wherein, V1 is the first battery voltage value, the magnitude of voltage that V0 is reference voltage, and X is default modulus sampling resolution (can be 8,10 or 12 etc.), AD1 is the first numerical reference magnitude of voltage.
In step S5, at telepilot, under control signal transmission state, according to default modulus sampling resolution, sample reference voltage to obtain a plurality of sample voltage value, and when telepilot completes control signal and sends using the minimum sample voltage value in a plurality of sample voltage value as the second numerical reference magnitude of voltage, and obtain the second battery voltage value according to default modulus sampling resolution, reference voltage and the second numerical reference magnitude of voltage.
It should be noted that, because telepilot only transmits control signal at the button Shi Caihui that is pressed, so at telepilot during in initial power-up state or standby (not transmitting control signal without button is pressed within a preset time interval), said telepilot is actually in control signal transmission state the control signal that makes telepilot work in simulation and sends state herein.
In addition, the step of obtaining the second battery voltage value according to default modulus sampling resolution, reference voltage and the second numerical reference magnitude of voltage in step S5 is specially:
According to following formula, calculate the second battery voltage value:
Wherein, V2 is the second battery voltage value, the magnitude of voltage that V0 is reference voltage, and X is default modulus sampling resolution (can be 8,10 or 12 etc.), AD2 is the second numerical reference magnitude of voltage.

Wherein, the step of obtaining battery electric quantity information according to the first battery voltage value and the second battery voltage value in step S6 is specially:
According to the first battery voltage value and the second battery voltage value, in default collection voltage-electric weight relation, obtain battery electric quantity information.
For example, default collection voltage-electric weight relation is as shown in the table:
N lattice in upper table (n equals 0,1,2,3 or 4) are battery electric quantity information, after getting battery electric quantity information, drive again remote controller displays module to show this battery electric quantity information, as shown in Figure 2, from battery electric quantity information is 4 lattice, every minimizing 1 lattice represent that battery electric quantity reduces 25%, so can allow thus user be well understood to very much the consumption situation of battery electric quantity.
In another embodiment of the present invention, the step of obtaining battery electric quantity information according to the first battery voltage value and the second battery voltage value in step S6 also can be specially:
According to following formula, calculate comprehensive battery voltage value:
