【正文】 re increasingly high requirements. But because this is pure handmade, so somewhat simple, but only after personally in order to better use and control of the machine. This paper mainly expounds the chess petition timer implementations. Chess Kuaiqi extend from the main circuit and the circuit. Display decoder, contestants and the input signal to the display output, with the control circuit and the opening the alarm circuit is posed of two parts, the above subject circuit. Through the Schmidt trigger and decoding circuit to generate pulse signals in the display output to achieve timing functions, constitute the expansion of the circuit. After wiring, welding, testing and other work chess Kuaiqi electronic referee timer forming.桂林電子科技大學實訓（論文）報告用紙 第 1 頁 共 18 頁目 錄引言...................................................................................................................................21 計數(shù)器基礎(chǔ)知識............................................................................................................2 概念....................................................................................................................................................2 主要構(gòu)成：........................................................................................................................................2 工作原理............................................................................................................................................3...........................................................................................................3 設(shè)計目的............................................................................................................................................3 設(shè)計要求............................................................................................................................................3...............................................................................................4...............................................................................................................4 秒脈沖電路 .......................................................................................................................................4 計數(shù)器電路........................................................................................................................................5 譯碼顯示電路....................................................................................................................................6 報警電路............................................................................................................................................75. 焊接要領(lǐng)...........................................................................................
