本文提出一種應用於工業物聯網的藍牙mesh網路設計。分析工業需求，依照Bluetooth SIG所制定的規範，規劃一套適合工業使用的標準化IIoT網路。本文將藍牙mesh裝置中的element依功能模組化，並在各個element加入property model作為功能標籤。若管理者整合這些property資訊，能快速知道網路內所有裝置內容。其中包含裝置名稱、地點、電量、韌體版本以及支援的功能等必要資訊，進一步結構化管理。Mesh裝置能透過不同的keys、group address設定，將裝置分成不同子網路或者分成功能導向和位置導向的群組，進行群組控制。為提供裝置的可維護性，本文設計藍牙mesh的無線韌體更新方案。在不影響裝置原有網路功能的狀態下，同時更新網路內所有需要更新的裝置。

This thesis proposes a Bluetooth mesh network design applied to the Industrial Internet of Things. Analyze the needs of the industry and plan a set of standardized IIoT networks suitable for industrial use in accordance with the specifications established by the Bluetooth SIG. In this thesis the elements in the Bluetooth mesh device are modularized by function, and each element is added with a property model as a function tag. If the administrator integrates these property information, they can quickly know the content of all devices in the network, including the device name, location, power level, firmware version, and supported functions and other necessary information, and further structure management. Mesh devices can be divided into different subnets or function-oriented and location-oriented groups through different keys and group address settings for group control. In order to provide the maintainability of the device, this article designs a wireless firmware update solution for Bluetooth mesh, which updates all devices in the network that need to be updated without affecting the original network functions of the device.
