Description

Technical Field

[0001] This invention relates to the fields of intelligent control, touch sensing, human-computer interaction and LED lighting control technology, specifically to a multi-channel intelligent control system that realizes LED light on / off control, color switching control and tactile feedback linkage control through a touch panel. Background Technology

[0002] Existing touch lighting control solutions typically require separate touch detection circuits, main control logic circuits, LED driver circuits, and feedback execution circuits. These functional modules are relatively independent, resulting in low system integration. This leads to a complex overall circuit structure, a large number of components, difficult wiring, and hinders product miniaturization and thinner design.

[0003] In addition, existing technologies generally suffer from the following problems: 1. Insufficient linkage between touch recognition and control; In some touch control systems, there is a lack of efficient linkage between touch signal acquisition and subsequent lighting control and feedback control, which can easily lead to problems such as response delay, unstable control or false triggering.

[0004] 2. The consistency of LED multi-channel control is poor; In multi-channel LED on / off control and color control applications, problems such as inconsistent brightness and unstable color switching can easily occur between different channels due to power supply fluctuations, differences in driving capability, or insufficient control precision.

[0005] 3. Insufficient system power supply stability; For systems that integrate touch, LED driving and feedback execution units, insufficient power supply regulation can easily lead to touch reference drift, abnormal LED display and unstable operation of feedback devices, thereby affecting the overall user experience.

[0006] 4. Inconvenient debugging and expansion after function integration; If touch input, LED output, communication interface and feedback device are arranged in a centralized manner, the lack of reasonable module division and interface reservation will hinder subsequent function expansion, fault diagnosis and product series development.

[0007] Therefore, there is an urgent need for a multi-channel intelligent control system that has a clear structure, stable control, high integration, and can take into account touch input, LED on / off and color control, as well as tactile feedback output. Summary of the Invention
