dual mode wearable device operating method based on a multi - fused composite sensor

摘要

The present invention relates to a method for operating a multi convergence sensor-based dual mode wearable device (100), which provides an interworking protocol interworking with a display device (200) for healthcare. The multi convergence sensor-based dual mode wearable device (100) comprises: a wearing unit (120) capable of being worn on an ankle of a user; and a body (110) combined with the wearing unit in a detachable way. The body (110) includes a power management unit, a preliminary sensor, an optical photoplethysmography (PPG) sensor, a temperature sensor, a motion sensor, a main control unit (MCU), an LED unit, a Bluetooth low energy (BLE) 4.0, a USB port, a lithium polymer battery, and a battery charger. The operating method of the multi convergence sensor-based dual mode wearable device provides an interworking protocol which interworks with a display device for healthcare. The interworking protocol analyzes an optimum communication distance and the maximum data capacity, hops frequency according to channel states, applies a routing sensor appropriate to an indoor space by fixing bugs through a repetition test, and has a remarkable effect of being convenient to carry and attach with low power.
