Smart ring and detection control method
By integrating the support bracket with the main circuit board in the smart ring and fixing the transmissive circuit board to the support bracket, the problem of angle deviation between the transmissive LED and the PD is solved, ensuring the stability and consistency of PPG performance.

AI Technical Summary
In existing smart rings, the relative positional relationship between the transmissive LED and the PD is affected by the angular deviation caused by the assembly error of the independent bracket, which affects the PPG performance, and the assembly precision requirements are high.
The support bracket and main circuit board are integrated into one structure. The transmission circuit board is fixedly connected to the support bracket. The transmission lamp group and the reflection lamp group share the same photoelectric sensor, eliminating the need for a separate bracket and ensuring the consistency of the relative position of the transmission LED and PD.
It reduces the dependence on assembly accuracy, avoids PPG signal attenuation and signal-to-noise ratio degradation, and improves detection stability and consistency.
