Smart bed notification system base on Internet of Things for fall prevention in patients with stroke

摘要

The Smart Bed Notification System is a system that alerts the movement of objects (patients with stroke) on the care mattress when patients are at risk of being dropped or falling. The notification device consists of two subsystems, namely hardware and software. In the hardware part, it consists of a camera to track patient movements, Raspberry Pi as a system controller that is equipped with a WiFi interface to transmit data wirelessly to smartphones that are equipped with Android-based applications. In the software part, however, openCV installed on Raspy is designed to picture the surveillance results of the webcam. Furthermore, the smartphone has an Android-based feature, which displays alerts of patient movement. Stroke patients may be tracked remotely over the Internet by nurses or their relatives.
