The paper gives the evidences for making use of auto - reclose technology in ineffectively grounded systems from its importance , feasibility and validity . to develop the single - chip microcomputer of the device , the paper does a lot of work of design hardware and software include using soft timer with task - plan solving the whole arrangement of the process 在選線裝置的實(shí)現(xiàn)方式上,本文提出了基于單片機(jī)方式的硬件電路的開發(fā)方案和軟件系統(tǒng)設(shè)計(jì)方案,嘗試了使用80c196kb的三個(gè)軟件定時(shí)器中斷結(jié)合任務(wù)型設(shè)計(jì)方法解決程序流程的問題。
On the basis of advanced electric control technology , my works are carry on analysis and design about the hardware and software of ecu . the idle speed control aim is make gasoline keep well property under the low rotation . in accordance with 465q gasoline specific conditions , we take use of fuzzy control theory on idle speed control of gasoline , and make step - motor to idling executive body . appling intel 80c196kb chip , we program idling the main order , software time implement break sub - order and delay sub - order in compilation language 怠速控制的目的則是保證在較低的轉(zhuǎn)速下保持汽油機(jī)具有良好的性能,我們?cè)诜治?65q汽油機(jī)的具體情況的基礎(chǔ)上,把模糊控制理論用在汽油機(jī)怠速控制方面,用步進(jìn)電機(jī)作為怠速執(zhí)行機(jī)構(gòu),并以intel的80c196kb單片機(jī)為主芯片設(shè)計(jì)了怠速控制系統(tǒng)的軟硬件,用intel匯編語言設(shè)計(jì)了怠速主程序,軟件定時(shí)器中斷服務(wù)程序,三相單三拍步進(jìn)電機(jī)正反轉(zhuǎn)子程序,延時(shí)子程序匯編軟件。
In the designation of software , the author adopts the modular designing method , and makes full use of the functions what the mcu offers , such as a / d function , interrupt function , pwm function , and software timer function . as a result , the following subroutines are programmed : a / d sample , read optic - electron coder signal , disposition of orientation interruption , z interruption , and software timer 在控制軟件的設(shè)計(jì)上,采用模塊化程序設(shè)計(jì)方法,充分利用單片機(jī)內(nèi)部提供的a d功能、中斷功能、 pwm功能、軟件定時(shí)器等功能,設(shè)計(jì)出了a d采樣子程序、讀編碼器信號(hào)子程序、定位中斷服務(wù)子程序、 z中斷服務(wù)子程序、軟件定時(shí)器中斷服務(wù)子程序等模塊化程序。
