针对飞行模拟器座舱数据采集的复杂性，设计了一种基于以太网分布式的数据采集控制系统，该系统是RCM5700微处理器模块上的以太网应用。在系统的基础上具体讨论了PoE技术的应用，在传输数据的网线上同时提供电流，提出并实现了一种包括辅助电源在内的完整可靠的PoE供电方案。设计采用美国国家半导体的LM5073和LM5576并根据不同的负载情况，进行稳定可靠的电压转换，以满足数据采集电路的要求。实验结果表明：该设计稳定可靠，满足低于13 W的采集节点供电要求，提高了模拟器信号采集系统的通用性和标准化程度，避免了以往数据采集节点单独繁琐的电源设计。 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.
