Low-power bluetooth-based wireless control system for a rhythmic device

Abstract

This invention relates to the fields of wireless control and Bluetooth communication technology, specifically a wireless control system for a rhythmic device based on Bluetooth Low Energy (BLE). The system includes a remote controller and a main unit for the rhythmic device. The remote controller comprises a battery, an input module, a status detection module, a first Bluetooth communication module, a remote control master module, and a prompting module. The main unit comprises a second Bluetooth communication module, a main unit control module, an audio processing module, and a motor drive module. The input module receives start, stop, parameter adjustment, or pause commands. The status detection module detects battery level and Bluetooth signal strength. The remote control master module sets transmission permissions based on a battery threshold and sends control frames with serial numbers. The main unit control module parses the control information and switches or overlays therapeutic and music signals to generate drive signals. The prompting module updates battery level, connection status, or operating parameter display based on operating status information. This system achieves one-handed wireless control, status feedback, and command permission control under low battery and signal abnormalities.
