planimeter n.【數學】測面儀,求積儀。

planimetry

According to this idea , this paper first introduces the basic technology to design the instrument . it includes the theory of the laser , measures to survey distance with laser , the theory of the step - motor , subsection technology of the step - motor , the working theory of the single - chip , expansion of the single - chip orderly . the following are the design of the control system of the planimeter according to the principle of the context . it consists of two parts 最后根據前文介紹的知識先對單片機控制系統進行了硬件電路框圖設計,依據夠用原則對元器件、設備的選擇進行計算、說明、選定,使系統成為擁有完整的包括a d采集、數據存儲器、 8155擴展的鍵盤顯示、 p1口及8155的pa口輸出控制的單片機硬件控制系統電路。

But , the former is not so easy , especially the anomalous plane . this paper plans to design a planimeter to solute this problem 本系統設計至少要包括單片機存儲器及i o擴展,人機通道,前向通道及后向通道的的軟硬件設計。
