| Summary: | 碩士 === 南臺科技大學 === 電子工程系 === 107 === In recent years, most vehicle drivers suffered poor mental status due to long hours of works and lack of sleep, resulting in a rate increase in vehicle accidents. To avoid or reduce the disaster caused by fatigue driving, the drowsiness-fatigue-detection (DFD) systems have widely been researched and developed. However, it still lacks related functions such as a useful/accepted DFD system and management of recording fatigue driving. To solve the problem mentioned above, this thesis proposes a DFD system, which is based on wearable smart glasses. The proposed system consists of a pair of smart glasses, in-vehicle infotainment system (IVI system), Sigfox cloud platform, and online information platform. A band-pass infrared sensing module is mounted on the proposed smart glasses and uses infrared reflection principle to detect the state of the driver’s eyes. We implement an algorithm in microcontroller to identify whether the driver is entering fatigue state. When the driver is in a state of fatigue, thus the proposed smart glasses will transmit a fatigue event to the IVI system via Bluetooth low energy (BLE). At this time, the IVI system will immediately trigger a sound to wake up the fatiguing driver.Furthermore, the IVI system also transmits the fatigue event to the Sigfox could platform via the Sigfox low power wide area network (LPWAN). Finally, the SigFox cloud platform adopts callbacks method to send fatigue events to the online information platform. The online information can display and check the driver’s fatigue event information such as license plate number, date, time, location, etc. As a result, the proposed DFD system can be achieved the purpose of road safety.
