Description

Technical Field

[0001] The utility model relates to the technical field of circuits, in particular to a universal remote control circuit capable of updating infrared signal formats. Background Art

[0002] Infrared signals are a type of radio signal, also known as infrared light, emitted by electromagnetic energy. Their wavelength is shorter than visible light, making most infrared light invisible. Infrared signals are primarily used in wireless remote controls, entertainment, security systems, and wireless data transmission. Household appliances such as air conditioners and televisions generally support infrared remote control. Security systems use infrared signals to detect changes in external space or paths, also known as infrared vision technology, which can be used to monitor indoor and outdoor activities. Infrared signals are widely used in today's lives. As an alternative to Bluetooth or Wi-Fi, infrared signals offer advantages such as greater efficiency, security, and bandwidth.

[0003] A universal remote control is a wireless transmitter and receiver that can decode infrared signals from various remote controls, store received infrared signals, and retransmit the infrared information. It primarily consists of a microprocessor integrated chip that generates remote control signals, a crystal oscillator, an amplifying transistor, an infrared light-emitting diode, an infrared receiving diode, a keyboard matrix, and a memory. Universal remote controls have brought significant convenience to people today. However, existing universal remote controls have a drawback: they can only transmit infrared signal formats that fall within a pre-existing infrared code library. Specifically, after leaving the factory, the internally stored infrared code library of a universal remote control can match most existing home electronic devices. However, if a subsequent home electronic device adopts a new infrared signal format that is not already stored in the previously stored infrared code library, the universal remote control will be unable to control these devices, such as new curtain boxes, air conditioners, televisions, and refrigerators. This limits the lifespan of universal remote controls, and the range of home electronic devices they can control remains limited in the long run, resulting in a suboptimal user experience.
