Abstract:
Objective:To design an alarm system for patients'tumble based on a six-axes attitude sensor so as to monitor patients'tumble during they lied in bed of hospital or they acted in ward of hospital.Methods:The internet of things (IOT) platform with six-axes attitude sensor and Zigbee module which adopted the functions of measurement and calculation based on six-axes attitude sensor were used to compose automatic alarm system for patients'tumble in ward of hospital.Arduino was adopted as the development platform of hardware to obtain the sensors data that were worn on patients through the I2C trunk method.And through implemented preprocess and numerical value filtering for data to perform posture calculation.Results:This design has realized the recognition for patient's current position and the alarm in time for sudden event of tumble.It could assist clinical workers to achieve better care for patients.Conclusion:This design basically realizes the function of monitoring and alarm for the situation of patient's tumble, but there are some problems includes sporadic misjudgment and oversize wearing hardware.It is planned to improve the practicability of the system by improving the algorithm and hardware platform.
