Embodiment Construction

[0029] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0030] Firstly, the specific implementation manner of the remote controller is introduced. The remote control includes a detection device for the battery voltage of the remote control. The detection device detects the battery voltage based on the control chip stored in the remote control, and displays the power prompt information according to the detection result, so that the remote control can detect the battery voltage in real time and save the battery power. The situation is displayed to the user, and the power information can be reflected to the user without adding additional hardware circuits, which is low in cost and convenient for the user to use.

[0031] Next, a specific implementatio...

Abstract

The invention discloses a remote control and a method and a device for detecting battery voltage of the remote control. The method for detecting battery voltage of the remote control includes: subjecting stabilized voltage of a control chip of the remote control to A/D (analog/digital) sampling to obtain a sample value, and connecting a reference voltage end of an A/D sampling channel arranged in the control chip to a battery of the remote control; calculating the battery voltage of the remote control according to the sample value; and displaying a battery prompt message according to the battery voltage. The battery voltage can be detected directly through the control chip of the remote control, the battery prompt message is displayed according to detection result, and battery level of the remote control is detected without increasing detection cost, and the method is simple and low-cost.

Description

technical field [0001] The invention relates to the field of remote controllers, in particular to a remote controller and a method and device for detecting battery voltage thereof. Background technique [0002] In daily life, mobile phones, cameras, DV, etc., mostly have a battery power display function, which can be detected and displayed according to changes in battery power, which is convenient for users to query and charge in time. However, there is no detection and display of battery power on the commonly used remote controller, so that the user cannot know the situation of the battery power when using the remote controller, so that the battery cannot be replaced in time, which has a certain impact on the use of the remote controller. [0003] In addition, the current implementation of battery power detection requires an external hardware detection circuit, which is costly and complicated to implement. [0004] Aiming at the problems of high cost and complicated implem...
