針對(duì)飛行模擬器座艙數(shù)據(jù)采集的復(fù)雜性，設(shè)計(jì)了一種基于以太網(wǎng)分布式的數(shù)據(jù)采集控制系統(tǒng)，該系統(tǒng)是RCM5700微處理器模塊上的以太網(wǎng)應(yīng)用。在系統(tǒng)的基礎(chǔ)上具體討論了PoE技術(shù)的應(yīng)用，在傳輸數(shù)據(jù)的網(wǎng)線上同時(shí)提供電流，提出并實(shí)現(xiàn)了一種包括輔助電源在內(nèi)的完整可靠的PoE供電方案。設(shè)計(jì)采用美國國家半導(dǎo)體的LM5073和LM5576并根據(jù)不同的負(fù)載情況，進(jìn)行穩(wěn)定可靠的電壓轉(zhuǎn)換，以滿足數(shù)據(jù)采集電路的要求。實(shí)驗(yàn)結(jié)果表明：該設(shè)計(jì)穩(wěn)定可靠，滿足低于13 W的采集節(jié)點(diǎn)供電要求，提高了模擬器信號(hào)采集系統(tǒng)的通用性和標(biāo)準(zhǔn)化程度，避免了以往數(shù)據(jù)采集節(jié)點(diǎn)單獨(dú)繁瑣的電源設(shè)計(jì)。 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.

Abstract: This reference design provides design ideas for a cost-effective, low-power liquid-level measurement dataacquisition system (DAS) using a compensated silicon pressure sensor and a high-precision delta-sigma ADC. Thisdocument discusses how to select the compensated silicon pressure sensor, suggest system algorithms, and providenoise analyses. It also describes calibration ideas to improve system performance while also reducing complexity andcost.

Abstract: Communication with 1-Wire slave devices requires a 1-Wire master. There are numerous ways to build a 1-Wire master (see reference design 4206, "Choosing the Right 1-Wire Master for Embedded Applications"). Thisdocument describes the DS1WM, a synthesizable 1-Wire master that can be implemented in an application-specificintegrated circuit (ASIC) or field-programmable gate array (FPGA).

With the Altera Nios II embedded processor, you as the system designercan accelerate time-critical software algorithms by adding custominstructions to the Nios II processor instruction set. Using custominstructions, you can reduce a complex sequence of standard instructionsto a single instruction implemented in hardware. You can use this featurefor a variety of applications, for example, to optimize software innerloops for digital signal processing (DSP), packet header processing, andcomputation-intensive applications. The Nios II configuration wizard,part of the Quartus® II software’s SOPC Builder, provides a graphicaluser interface (GUI) used to add up to 256 custom instructions to theNios II processor

The main objective of this book is to present all the relevant informationrequired for RF and micro-wave power amplifier design includingwell-known and novel theoretical approaches and practical design techniquesas well as to suggest optimum design approaches effectively combininganalytical calculations and computer-aided design. This bookcan also be very useful for lecturing to promote the analytical way ofthinking with practical verification by making a bridge between theoryand practice of RF and microwave engineering. As it often happens, anew result is the well-forgotten old one. Therefore, the demonstrationof not only new results based on new technologies or circuit schematicsis given, but some sufficiently old ideas or approaches are also introduced,that could be very useful in modern practice or could contributeto appearance of new ideas or schematic techniques.
