Engine parameter acquisition display system is an important member of helicopter seat room display system , and is made of engine parameter acquisition unit ( epu ) and engine parameter display ( epd ) . epu is joined with engine electronic controller , fuel manage system , engine and accumulator by the wire . it acquire the parameter of engine , for example , analog signals , frequency signals and discrete signals , etc . then data processing , compare data and operation is executed 發動機參數采集器通過硬連線與發動機電子控制器、燃油管理系統、發動機及蓄電池相連,采集模擬量、頻率量及離散量信號等參數,并對采集的數據進行運算、比較與處理,最后通過標準rs ? 422a串口和發動機參數顯示器及其它設備進行通訊。

Because of the interaction of urushiol chains and cus , the transformation temperature tg of hybrid - epu / cus was higher than that of epu . heat stability and solvent resistance were also improved . the interaction and network of urushiol chains were efficiency to inhibit the dimension of cus nanoparticles 漆酚鏈段與cus之間的作用,以及漆酚交聯網絡的存在可有效阻止cus顆粒尺寸的增大,但漆酚交聯網絡產生的空間位阻也在一定程度上降低了sz ”的擴散。

In at last , on base of electropolymerization of urushiol , electropolyurushiol / cus hybrid film ( hybrid - epu / cus ) was manufactured by the method of ion exchange process . then hybrid - epu / cus was characterized by ft - ir , fluorescence , dmta xrd and tem 最后,本文在電化學聚合漆酚的基礎上,用電化學聚合漆酚銅配合物,在一定條件下與nfos作用,可獲得聚合漆酚納米clls雜化材料。

Firstly , the dissertation expatiate the develop of epu ' s software and hardware . the hardware is a data acquisition system based on the ps multiprocessor architecture 硬件是以主從式多處理器結構為核心數據采集系統,主機和從機分別采用ti公司浮點dsp芯片7ms320c31pq和定點dsp芯片tms320f240 。

Finally , the emulator software based on virtual instrument is introduced , and it is used in the system test of epu 最后,介紹了基于虛擬儀器的仿真軟件在發動機參數采集器系統測試中的應用。

At last epu communicates the data to epd and other equipment of the helicopter by thers - 422a 首先,在本論文中詳細闡述了發動機參數采集器的軟硬件的開發。
