碩士 === 元智大學 === 機械工程學系 === 105 === The purpose of the research is to develop the smart sensing seat integrated with Bluetooth Low Energy information structure and apply internet control structure to combine electric wheel chair with current sensor and sensing seat. With internet control structure application, the wheelchair can realize that the usage data of wheel chair user will be uploaded through the internet. There are two major development priorities in this design: (1) Smart seat apply advertising function of Bluetooth Low Energy. The smart seat can achieve lower energy consumption than establishing Bluetooth connection with Bluetooth advertising function. Furthermore, Bluetooth advertising function allows the device information provides to multiple Bluetooth receivers. This research uses the smart Bluetooth receiver (WhizConnect) from SEDA G-Tech Company to collect Bluetooth advertising data of smart the sensing seat. When the WhizConnect receives the latest data from smart seat it will upload the information to the cloud server. Any other smart device can request the data from the cloud server. This scenario demonstrates the application that brings Bluetooth device into the internet of things structure. (2) This research using carbon fiber material and hub-motor to complete electric wheelchair body and integrating the network chip microprocessor with the wheelchair to be the internet control structure. With this structure, the electric wheel chair can collect sensing seat and current sensor data to upload it to the cloud server. The smart mobile device can update the latest information from the electric wheel chair. In addition to receiving sensor data, the smart mobile device are allowed to send the control command to the electric wheel chair as the wheel chair control structure of internet of things. If any other smart devices need the data, can also request it from the cloud server. This research demonstrates the sensor application with the internet of things concept as connected wheelchair.
