In modern medicine, smart wireless connected devices are gaining an increasingly important role in aiding doctors' job of monitoring patients. More and more complex systems, with a high density of sensors capable of monitoring many biological signals, are arising. Merging the data offers a great opportunity for increasing the reliability of diagnosis. However, a huge problem is constituted by synchronization. Multi-board wireless-connected monitoring systems are a typical example of distributed systems and synchronization has always been a challenging issue. In this paper, we present a distributed full synchronized system for monitoring patients' health capable of heartbeat rate, oxygen saturation, gait and posture analysis, and muscle activity measurements. The time synchronization is guaranteed thanks to the Fractional Low-power Synchronization Algorithm (FLSA).
在现代医学中，智能无线连接设备在帮助医生监测患者方面发挥着越来越重要的作用。越来越多的复杂系统涌现出来，这些系统具有高密度的传感器，能够监测许多生物信号。合并这些数据为提高诊断的可靠性提供了巨大的机会。然而，一个巨大的问题是同步。多板无线连接监测系统就是分布式系统的一个典型例子，而同步一直是一个具有挑战性的问题。在本文中，我们提出了一种用于监测患者健康的分布式全同步系统，该系统能够进行心率、血氧饱和度、步态和姿势分析以及肌肉活动测量。时间同步是通过分数低功耗同步算法（FLSA）来保证的。
