針對飛行模擬器座艙數據采集的復雜性，設計了一種基于以太網分布式的數據采集控制系統，該系統是RCM5700微處理器模塊上的以太網應用。在系統的基礎上具體討論了PoE技術的應用，在傳輸數據的網線上同時提供電流，提出并實現了一種包括輔助電源在內的完整可靠的PoE供電方案。設計采用美國國家半導體的LM5073和LM5576并根據不同的負載情況，進行穩定可靠的電壓轉換，以滿足數據采集電路的要求。實驗結果表明：該設計穩定可靠，滿足低于13 W的采集節點供電要求，提高了模擬器信號采集系統的通用性和標準化程度，避免了以往數據采集節點單獨繁瑣的電源設計。
Abstract:
Aiming at the complexity of large avion simulation and controlling，the simulator cabin distribute data collecting and control system was designed. This system is the application of RCM5700 on Ethernet. Based on this system，PoE technique that makes Ethernet can also provide power were expounded with emphasis and included FAUX design the PoE resolution was realized. To achieve the requirement of this system，LM5073 and LM5576 were used to DC-DC switch. From the data of experiment，the design filled the requirement of power-need of node whose power was lower than 13W. The application of the technique can advance the degree of simulation data collections currency and standardization and avoid designing additional power system.

在網絡安全中經常會遇到rootkit，NSA安全和入侵檢測術語字典( NSA Glossary of Terms Used in Security and Intrusion Detection)對rootkit的定義如下：A hacker security tool that captures passwords and message traffic to and from a computer. A collection of tools that allows a hacker to provide a backdoor into a system, collect information on other systems on the network,mask the fact that the system is compromised, and much more. Rootkit is a classic example of Trojan Horse software. Rootkit is available for a wide range of operating systems.
