A study of modeling and control of proton exchange membrane fuel cell stack systems 質子交換膜燃料電池電堆系統建模與控制研究
Rack - and - stack systems can be large if the test requires many different instruments 如果測試需要很多不同的設備,堆架式系統可以做的很大。
The thesis chooses the four - layers structure as the rudiment of our protocol stack system , which includes physical layer , data link layer , network layer and application layer 本文選擇了四層結構作為協議棧體系結構的雛形,即:物理層、數據鏈路層、網絡層、應用層。
The goal of this thesis is to give a scheme on the application of wireless sensor network system indoor . first of all , we have a deep research on the ‘ telos ’ node , secondly , we build up a stack system structure of wireless sensor network to monitor the temperature of the building intellectively , design and realize the network stack including physical layer , data link layer , network layer and application layer . finally , we debug the software in order to verify the network layer and the application layer 本文以智能樓宇溫度監測應用為設計目標,以em2420射頻芯片和atme128l單片機為設計載體,在詳細研究telos節點方案基礎上,對面向設計目標的室內無線傳感器網絡節點的物理層、數據鏈路層、網絡層和應用層之間的網絡協議棧進行了實現性設計,建立了立足設計目標的無線傳感器網絡協議體系,并在avrstudio4 . 11調試環境下對網絡層和應用層設計正確性進行了調試驗證。
