Description

Technical Field

[0001] This invention relates to the field of infrared remote control technology, and more specifically, to a method, device, and storage medium for dynamically reconfiguring button codes of remote controls for infrared controlled devices through software architecture innovation. Background Technology

[0002] Traditional infrared-controlled devices (such as smart lights, fans, and air conditioners) rely on a static encoding mapping table embedded in the device's memory at the factory. This mapping table is fixedly associated with preset remote control button codes and device control commands. This static binding architecture results in a tight coupling between the device and a specific remote control, leading to the following inherent technical problems: losing the original remote control will cause the device's main functions to fail; users cannot use other unused remote controls; and remote controls between different devices are not interchangeable. The existing architecture lacks a flexible, hierarchical configuration triggering mechanism, failing to intelligently provide the optimal configuration entry and user experience based on the device's own hardware resources. Summary of the Invention

[0003] This invention aims to overcome the aforementioned shortcomings of existing technologies, and its core lies in proposing an innovative software architecture. In infrared controlled devices, this architecture replaces the original static mapping table with a dynamically modifiable and reconfigurable mapping table, and designs an independent remote control button configuration mode to safely and conveniently update this table.

[0004] To achieve the above objectives, the present invention provides a method for reconfiguring remote control buttons for infrared-controlled devices. The method manages a reconfigurable mapping table and switches the device between an operating mode and a configuration mode. In configuration mode, the device decodes the infrared signal from an external remote control, obtains its button code, and dynamically associates this code with a predetermined control command of the device before updating the mapping table. In operating mode, the device responds to remote control operations based on the updated mapping table.

[0005] Furthermore, this invention defines three triggering methods for entering the remote control button configuration mode: power-on triggering, external triggering (via a physical input device on the device itself), and command triggering (via a learned mode switching command). The external triggering and command triggering are bidirectional triggering mechanisms and can also be used to switch back from the configuration mode to the operating mode. In particular, whether the device has the physical input device determines its initial state strategy after power-on, thereby achieving an optimal balance between cost and user experience.

[0006] Accordingly, the present invention also provides an infrared controlled device for implementing the method, and a computer-readable storage medium storing related programs. Beneficial effects

[0007] Compared with the prior art, the present invention has the following significant advantages: Architectural innovation: It realizes a paradigm shift from "static coding mapping" to "dynamic reconfigurable mapping" at the device software level.

[0008] Intelligent status management: Provides intelligent triggering strategies based on hardware configuration, ensuring availability and convenience for various devices (from extremely low cost to high user experience).

[0009] Extremely versatile and flexible: Enables the device to learn and adapt to remote controls with any encoding format compatibility.

[0010] High cost-performance ratio: The core is implemented in software, the hardware cost is extremely low, and the storage solution can be flexibly selected according to the needs. Attached Figure Description

[0016] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. These embodiments are only used to explain the present invention and are not intended to limit it.

[0017] See Figure 1 The infrared controlled device 100 includes a processing unit 101, a memory 102, an infrared signal interface 103, and a user instruction unit 104. The memory 102 maintains a reconfigurable mapping table 105.

[0018] Combination Figure 2The method and process are as follows: S201: The device is powered on and enters the operating mode or configuration mode according to the preset strategy.

[0019] S202 / S203: Listen for signals in running mode to determine if it is a configuration trigger event (such as an external button press or receiving a specific instruction code). If so, enter configuration mode.

[0020] S204-S206: In configuration mode, guide the user to learn the external remote control button codes and update the reconfigurable mapping table 105.

[0021] S207: Exit configuration mode after the exit conditions are met (such as completion, timeout, or receipt of a switch command).

[0022] S208: In operating mode, respond to the remote control according to the reconfigurable mapping table 105.

[0023] This invention employs different strategies depending on whether the device has a physical input device (such as a dedicated button): Devices without physical input devices must employ a "power-on configuration mode entry" strategy. This is a safety design to ensure the device never becomes unusable. After configuration, the user can exit configuration mode using the learned "mode switching command" button.

[0024] For devices with physical input devices, a more optimized strategy can be adopted. For example, the device can directly enter the operating mode upon power-on, and enter the configuration mode by pressing a physical key when configuration is required. Both physical key triggering and command triggering are bidirectional, allowing for flexible switching between operating and configuration modes.

[0025] This design allows the invention to be perfectly adapted to products with different cost and experience requirements.

[0026] Smart bulb (no dedicated button): Upon first power-on, the bulb slowly flashes to enter configuration mode. Users can then learn the on / off and dimming functions using an old TV remote control before using it.

[0027] High-end fan (with dedicated button): The fan is in standby mode after power-on. Users can press and hold the "Settings" button on the unit to enter configuration mode and learn how to control fan speed and oscillation using the air conditioner remote. Afterwards, a short press of the "Settings" button or a custom "Mode" button on the remote will switch between the two modes.

[0028] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
