At the moment when the hand of the massive time - piece, representing endymion asleep, pointed to nine on its golden face, and the hammer, the faithful type of mechanical thought, struck nine times, the name of the count of monte cristo resounded in its turn, and as if by an electric shock all the assembly turned towards the door
當金面大時鐘上的時針指到九點，當機械的鐘錘敲打了九下的時候，司儀報出了基督山伯爵的名字，象觸了電一樣，全場的人都把他們的視線轉向了門口。基督山伯爵穿著黑衣服，象他往常一樣的簡單樸素。Using domestic strained integrated resistor as weighing sensor, at89c52 single chip as control unit, combined with arithmetical magnification, analogtodigital conversion ( a / d ), real time clock, liquid crystal display ( lcd ), and series communication interface, a minitype automatic weighing lysimeter is developed. that made measurement of evapotranspiration become conveniently and effectively in studying on water use of crops
為了方便、有效地測定植物的蒸散，為水分利用研究提供價廉物美、簡單易用的儀器，本研究利用國產的集成電阻應變式稱重傳感器，採用at89c52單片機作為控制單元，結合運算放大、模數轉換、實時時鐘、液晶顯示、數據存儲、串列通信等外圍介面電路，研製了小型自動稱重式蒸散儀。According to the request of this subject, we have developed the system hardware and software for the slave device and the inspection software running on the pc. in this paper all of the followings is illustrated detailedly, such as the research on the principles of measurement and its realization, three means of water - level measurement that are separately based on photo electricity coder, pressure sensor and potentiometer ; selection of the microchip, we choose an advanced integrated soc ( system on chip ) microchip c8051f021 as the main controller ; realization of signal sampling, processing and its conversion in the mcu ; application of high precision 16 bits adc cmos chip - - ad7705 in our system, designing its interface with the microchip and relevant program ; using a trickle charge timekeeping chip ds1302 in the system which can provide time norm and designing of its i / o interface and program ; additionally, a 4 ~ 20ma current output channel to provide system check - up using ad421. in the system, ad421, ad7705 and the microchip compose spi bus ; to communicate with the master pc, here we use two ways which are separately rs232 and rs485 ; moreover, there are alarm unit, keyboard unit, power supply inspection unit and voltage norm providing unit in the system
針對研製任務的要求，課題期間研製了下位機系統硬體和軟體，開發了上位機監控軟體，其中所作的具體工作包括：測量原理的研究和在系統中的實現，在本次設計中用三種方法來進行水位測量，分別是旋轉編碼器法、液位壓力傳感器法和可變電阻器法；主控晶元的選擇，我們選用了高集成度的混合信號系統級晶元c8051f021 ；實現了信號的採集和處理，包括信號的轉換和在單片機內的運算；高集成度16位模數轉換晶元ad7705在系統中的應用，我們完成了它與單片機的介面設計及程序編制任務；精確時鐘晶元ds1302在系統中的應用，在此，我們實現了用單片機的i o口與ds1302的連接和在軟體中對時序的模擬，該晶元的應用給整臺儀器提供了時間基準，方便了儀器的使用；另外，針對研製任務的要求，還給系統加上了一路4 20ma模擬信號電流環的輸出電路來提供系統監測，該部分的實現是通過採用ad421晶元來完成的，本設計中完成了ad421與單片機的spi介面任務，協調了它與ad7705晶元和單片機共同構成的spi總線系統的關系，並完成了程序設計；與上位機的通信介面設計，該部分通過兩種方法實現： rs232通信方式和rs485通信方式；系統設計方面還包括報警電路設計、操作鍵盤設計、電源監控電路設計、電壓基準電路的設計。In a book written by an electronics expert who once participated in the us star wars program, the author discussed his findings in his studies on several fallen ufos unidentified flying object. according to him, ufos do not look very big from the outside, but after entering them, one might spend twenty minutes walking without reaching the opposite end due to a conversion of time and space. unlike an aircraft cockpit with dashboards and maneuvering devices, the ufos have only a few seats, surrounded by walls which themselves serve as jumbo tv monitors
他在對多種墜落的幽浮外星人飛行器考察研究時發現，從外面看幽浮並不很大，但進去后卻走二十多分鐘走不到頭時空轉換，而且裏面沒有像飛機駕駛艙內那樣眾多的儀表及操縱裝置，只有幾個坐椅，四周的墻壁就是大屏幕觀測電視，內部也沒有復雜的集成電路，只有大的晶體塊，整個飛行器完全是在外星人頭腦發出的電磁波控制下運行。Meteorological instrument recording cylinder with an internal clock revolving with it
