Abstract

The invention belongs to the field of electric quantity detection, and provides a remote controller electric quantity detection method and device. Reference voltage of a remote controller in a standby state and a control signal transmitting state is respectively sampled and a first digital reference voltage value and a second digital reference voltage value are generated. Then a first battery voltage value and a second battery voltage value are acquired according to preset analog-digital sampling resolution, reference voltage, the first digital reference voltage value and the second digital reference voltage value. Finally battery electric quantity information is acquired according to the first battery voltage value and the second battery voltage value and displayed so that the battery electric quantity information is further confirmed by acquiring two different battery voltage values under different working states of the remote controller, and thus accuracy of a battery electric quantity detection result of the remote controller is enhanced.

Description

technical field [0001] The invention belongs to the field of electric quantity detection, and in particular relates to a remote control electric quantity detection method and device. Background technique [0002] At present, more and more household appliances begin to use remote controllers to realize remote control, and because remote controllers are generally powered by batteries, in order to enable users to clearly know the battery power status, the existing technology generally uses two methods to detect battery power Finally, the battery power is displayed. The first method is to detect the battery voltage and estimate the power according to the voltage. If the voltage is high, the power is high, and if the voltage is low, the power is low. The second method is to estimate the power by detecting the internal resistance of the battery. The higher the internal resistance, the lower the power. [0003] However, since the operating current of the remote control is small an...
