摘要

Digi International XBee是一種可透過協調器（Coordinator）、路由器（Router）及端點（Endpoint），進行從屬設備無線數據交換的網路模塊，市場上已有眾多與其相容的設備販售，使用者可以靈活地選擇進行無線系統建構。本文將介紹工研院機械所發展的無線裝置應用，透過低功耗的微控制器（MCU），經過自訂的通訊協議，並以實現雙向控制，避免封包漏失及確保重送機制，完成高強度的雙向控制遠距離節點控制器。含底層負責採擷數據的感測層端點盒（Endpoint Box），以及透過Digi-Mesh無線傳輸數據的通訊層，中層提供工業物聯網通訊標準閘道器的雙向轉換協作器（Gateway Coordinator），以及上層後台生管製造或雲端系統。

Digi International XBee is a network module that can exchange wireless data between slave devices through Coordinator, Router and Endpoint. Many compatible options are available in the market, so users can flexibly constrcut wireless system choose the wireless system construction flexibly. This article introduces a wireless device developed by the ITRI/MMSL based on a low-power MCU and a customized communication protocol to achieve two-way control which minimizes packet loss and ensures the re-delivery mechanism. A high-intensity, two-way controller based on this is also introduced. The proposed application is a four-layer architecture including an Endpoint Box as the bottom layer which is responsible for data collection, a communication layer for wireless data transmission through Digi-Mesh, a two-way conversion Gateway Coordinator as the IIoT communication standard gateway, and the upper backstage manufacturing system or cloud system.
