This paper proposes a ˇ§The Development of a Conceptual Assistive Device with Multi-Signals Distinguishment Capabilityˇ¨, the purpose of this device is to effectively distinguish between different types of signals when they are transmitted wirelessly at the same receiver for subsequent applications. What the device is designed to handle are three types of signals that are most likely to cause immediate danger to the elderly, namely, ECG signals related to cardiovascular diseases, tilt signals related to falls, and GPS signals to prevent being lost. Therefore, the hardware architecture of this device includes a self-designed hand-held ECG sensor using brass as the sensing material, a fall detection module using a three-axis gyroscope, and a wireless data transmission interface made up of an Arduino microcontroller and a WIFI module in combination with a Google Map and GPS positioning module. In terms of software, LabVIEW software is used as the development tool for the HMI window. Based on this, we developed the ECG display interface, fall detection interface, and GPS positioning interface. This system has been tested and proven to be feasible. In the future, the system can be transferred to various assistive devices for the elderly for more usefulness. |
