| Summary: | 碩士 === 國立臺北科技大學 === 電機工程系研究所 === 102 === The research and design of this thesis focus on the wireless smart controller for traditional infrared remote controlled household appliances. Aiming at developing new remote control used in a smart home, we proposed an ensemble of a smart device, central controller, IR LED and three-level communication structure between appliances.
On the first level, we designed a smartphone APP that provides the user the ease to control and manage his/her household appliances. It sends commands to a central controller via Wi-Fi communication protocol to provide the central controller calibration for corresponding IR code. The second level is the communication between the central controller and the IR LED. With ZigBee acting as the communication bridge, the control commands are sent using corresponding IR codes to the specified IR LED device. On the third level, the user can control household appliances using IR LED with IR communication protocol.
We have created two kinds of user interface in this study. One is an interface built in a smartphone, i.e. an Android APP. Considering the fact that most people bring smart phones along wherever they go, we integrates user interface with smart devices so that the user can easily control his/ her household appliances from a distance. The other user interface was inspired by understanding that it may be difficult for the elderly to use smart devices. A hand-held remote control device with RFID communication protocol was also developed along with identification tags on every household appliance, giving the assemblage its directive character. The word "directive" in this essay simply means that when the user "directs" the remote control at the designated appliance, the interface automatically switches to the corresponding control page. To demonstrate how effective the ensemble is, a mini installation was built to simulate a household setting. Using the structure proposed, traditional household appliances can be managed and controlled.
