Description

Remote control battery prompt system

The present invention relates to a power alert system and, more particularly, to a remote power alert system.

The invention of the remote control brings great convenience to modern human life. The earliest remote control used to control television was the wired remote control developed by Zenith, an American electrical company in the 1950s. In 1955, the company developed a wireless remote control called Flashmatic. However, this device has no way of telling if the beam is coming from the remote control and must be aligned before it can be controlled. Robert 1956. Robert Adler developed a remote control called the Zenith Space Command, the first modern wireless remote control. This remote control uses ultrasound to adjust the channel and volume so that each button emits a different frequency. However, such devices may also be interfered with by ordinary ultrasound, and some people and animals (such as dogs) can hear the sound of the remote control. In the 1980s, when semiconductor devices that transmit and receive infrared rays were developed, infrared rays gradually replaced ultrasonic control devices. Even though other wireless transmission methods (such as Bluetooth, RF radio, WiFi, etc.) have been continuously developed in recent years, infrared remote control technology has been widely used until now.

However, with the development of the remote controller, the function of the remote controller is also increasing, accompanied by the problem of accelerated power consumption. The user cannot accurately know the time when the remote controller replaces the battery or charges, so there is often a situation in which the pressing remote controller does not respond to the failure of the appliance, or there is no backup battery when the battery is replaced.

In view of this, the present invention provides a remote controller power prompting system including a remote controller equipped with a battery and an electronic device. The remote controller includes a button unit, a controller, and a power detecting module. The button unit includes a plurality of buttons. When any button is pressed, the button unit sends a button code corresponding to one of the buttons. The controller is connected to the button unit for receiving the button code and transmitting a detection message after receiving the button code. The power detection module is connected to the controller for receiving the detection message, and the battery detection module performs the battery detection after receiving the detection message, and sends a power message to the controller according to the power detection result, and then controls The device generates a button message according to the button code and the power message, and the button message is sent by the remote controller. The electronic device is connected to the remote controller for receiving the button message and generating a corresponding operation according to the button message. Wherein, when the power detecting module detects that the battery power is lower than a threshold, the power detecting module transmits a power message including a low battery key code to the controller, and then the remote controller sends the low battery key code. The button message is sent to the electronic device, and the electronic device generates a corresponding prompt message according to the received low battery button code.

In practical applications, when the battery detection module detects that the battery power is higher than the threshold, the battery detection module transmits a power message that does not include the low battery button code to the controller.

In a specific embodiment, the remote controller further includes a transmitting unit, and the remote controller uses the transmitting unit to send the button message to the electronic device.

In one embodiment, the electronic device includes a receiving module, a processor, and a display screen. The electronic device uses the receiving module to receive the button message; the processor is connected to the receiving module, and the processor is configured to generate a corresponding operation and the prompt message according to the button message. A display screen is connected to the processor for displaying a prompt message.

Compared with the prior art, the present invention provides a remote battery power prompting system, which adds a power detecting module and a set of hidden low battery key codes to the remote controller without changing the user's operation of the remote controller. . When the user presses the remote controller, the battery detection module automatically detects the battery power of the remote controller. If the battery of the remote control is too low, the battery detection module transmits the low battery key code to the electronic device along with the original operation key code, and displays the low battery key code on the display screen to remind the user to replace the battery. The power detecting module of the invention only needs to judge whether the battery power is higher or lower than the threshold, and the low battery key code is transmitted to the electronic device together with the original operating button code, so as to be the most compact The component reaches the low battery alert function.
