現今的物聯網(IOT)技術在蓬勃發展,參與的廠商愈來愈多,但也造成各家廠商的感應器(Sensor)規格沒有統一的規範,互不相通。為了解決這個情況,本篇論文提出用一個公開的感應器描述語言的標準建立Sensor Ontology,搭配實驗室同學做的Code Generation,讓 IOT 閘道器 (IOT Gateway)可以存取用戶購買的不同廠商的感應器的資料。 另外我也嘗試著研究如何直接跟 Fitbit 追蹤器(Fitbit tracker)存取用戶的運動資料,讓我們的 IOT 閘道器能夠支援更多裝置。;Internet of Things (IOT) technology in the vigorous development of more and more manufacturers involved, but also caused various manufacturers of sensors (Sensor) specifications are not uniform. In order to solve this situation, this paper proposes to build a Sensor Ontology with an open sensor description language, so that the IOT Gateway can access the different vendors sensor data.In addition, I also tried to study how to access the Fitbit tracker directly to get user activity data, so that our IOT gateway can support more devices.
