Analog Devices / Maxim Integrated MAXREFDES143參考設計
Maxim MAXREFDES143參考設計是一種物聯網(IoT)內嵌安全參考設計,建造用於透過授權和通知網絡伺服器來保護工業感應節點。 硬件包括一個周邊設備模組,用於體現監測過濾器操作溫度和剩餘壽命的受保護感應器節點。 該裝置還包括一個mbed遮罩,代表著負責監視一個或更多感應器節點的控制器節點。 它採用層級式設計,每一個控制器節點將來自所連接感應器節點的資料傳送給網絡伺服器,該伺服器保留集中化的日誌,並視乎需要發出通知。 mbed遮罩包含一個Wi-Fi模組、一個具有1-Wire®主函數的DS2465協處理器、一個LCD、數個LED和按鈕。 受保護的感應器節點包含一個DS28E15驗證器、一個DS7505溫度感測器和一個MAX44009光感應器。 mbed遮罩透過板上Wi-Fi模組與網絡伺服器進行通訊,並透過I
2C和1-Wire與受保護的感應器通訊。
