本文旨在使用几种三轴加速度传感器装置，在发生意外跌倒时对受伤的身体部位进行关节传感。该模型将分布在身体各部位的传感器反馈的信息通过无线传输设备传输到计算机进行进一步分析和判断，并采用认知调节方法来调整身体各部位在不同运动中的加速度范围。当加速度明显超过通常的加速度范围时，该模型可以确定可能发生坠落事故。此外，发生跌倒事故后，可以将冲击加速度与正常（习惯）加速度进行比较，以确定受伤程度。这项研究还实现了用于分析的传感系统。该系统将可能承受较大冲击力的身体部位标记为红色，以便为医护人员提供更多信息，做出更准确的判断。
This paper aimed to use several triaxial acceleration sensor devices for joint sensing of injured body parts, when an accidental fall occurs. The model transmitted the information fed by the sensors distributed over various body parts to the computer through wireless transmission devices for further analysis and judgment, and employed cognitive adjustment method to adjust the acceleration range of various body parts in different movements. The model can determine the possible occurrence of fall accidents, when the acceleration significantly exceeds the usual acceleration range. In addition, after a fall accident occurs, the impact acceleration and normal (habitual) acceleration can be compared to determine the level of injury. This study also implemented a sensing system for analysis. The area of the body parts that may sustain greater impact force are marked red in this system, so that more information can be provided for medical personnel for more accurate judgment.
