讀取脈沖 的英文怎麼說
中文拼音 [dòuqǔmàichōng]
讀取脈沖
英文
strobe-
It can directly read data of mechanical meters immediately without counting pulse. it realizes remote valve control and extensible prepay function. its data transmission is based on international popular standard m - bus for all types of consumption meters, characterized by reliability, convenience, opening
特點:直接讀取表計的機械讀數,無需累計脈沖,僅在抄表瞬間加電工作;可實現遠程閥控;可擴展預付費功能;數據傳輸採用消費類儀?國際通行標準m - bus ,可靠、方便、開放。Once data has been written in dram, charges stored in each capacitor must maintain more than the refresh time so that the information stored in each dram cell can be read out correctly
數據一旦被寫進dram ,每個小電容上電荷的存儲時間就必須大於dram的刷新脈沖時間,如果由於漏電流致使存儲的電荷丟失,就會導致數據讀取的誤操作。Several key techniques of carving and milling machine cnc system are deeply studied they include : the transformation, data rebuild and interface design of huge volume nc program produced by cam ; the algorithm of cubic parametric spline pre _ interpolation and high speed real time interpolation in the cnc system, which. will gain a much higher surface precision and cutting speed ; methodology and algorithm of movement velocity acceleration control on a real time forecast _ and _ prejudge basis is designed. therefore, a smooth movement is insured. the shake and noise problem caused by non _ uniform pules for driving stepping or servo motor is solved by an improving algorithm to generate uniform pules
同時,本文對基於統一的pc平臺的雕銑機數控系統中的幾項關鍵技術進行了深入的研究,包括: cam生成加工程序的傳送、接收、讀取及其加工鏈表的生成和實時重構;對cam生成的離散數據進行三次參數樣條插值和基於累加弦長的三次參數樣條插補控制,保證加工工件表面的精度和光順性;設計具有「前瞻」功能的自動升降速控制方法,保證加工過程的平穩性;通過脈沖均勻化,有效地解決加工過程中因為脈沖不均勻而引起的震動問題。This system is developed based on high performance, low cost and many controllers inside of the embedded processor, and enlarged gpio for the plat of the hardware and software. this system is applied to the high - speed numerical control carving machine. show the operate interface by lcd, input the control code from the keyboard, the data is readed from the usb interface and store that in sdram
本系統應用於高速數控雕刻機,以lcd為人機可視化操作界面,以編碼鍵盤為操作控制部分,以嵌入式處理器s3c44b0x晶元為核心,文件數據經usb口讀取u盤中的雕刻數據文件暫存於sdram中,經嵌入式處理器進行相關演算法處理,得出相應參數傳送到fpga ,由fpga控制輸出脈沖和脈沖間延時,通過高速光耦隔離( 2mbit / s )后輸出,控制步進電機的運轉。分享友人
