逆計時數(shù)顯定時器的設計
1萬字 28頁
[摘要] 本文介紹了一種電子定時器.定時時間用數(shù)字顯示.并進行逆計數(shù).當計數(shù)器顯示為 “ 0 ” 時.控制器會自動切斷或打開用電器的電源, 定時時間范圍 1~ 990分鐘。該定時器可替代目前一些家用電器中的機械定時器。
倒計時時定時器的用途很廣泛,它可以用作定時器,控制被定時的電器,實現(xiàn)定時開或者定時關,在定時的過程中,隨時顯示剩余時間, 它還可以用作倒計時計數(shù)器。由三位數(shù)碼管直觀顯示倒計時計數(shù)狀態(tài)。
關鍵詞:電子定時器,數(shù)字顯示,倒計時
[Abstract] This article introduced one kind of electronic timer. Fixed the time is demonstrated with the digit. And carried on ploting the number. When the counter is demonstrated “0”, The controller automatic turnoff or opens with power source of electric appliance,the range of fixed time is 1~ 990 minutes.This timer may substitute some mechanical timer of domestic electric appliances in the present.
The use of the count down timer is very widespread, it can be used as the timer,which controls the electric appliance what be fixed time, realizes fixed time opened or closed, in the process of fixed time, momentarily demonstrates the surplus time, it can be also used as the countdown counter. Display the condition of the countdown immediately by three nixietube.
Key word: electronic timer ,digit demonstration,countdown
