为了研究电气开关电接点的机械抖动次数,特别是为了测量电接点的机械抖动次数,研制了基于微控制器的机械抖动次数测量系统。论述了测量系统的硬件设计和软件设计,给出了电路原理图和程序流程框图,以及关键程序源代码。对轻触按钮开关、复式按钮开关、单刀双掷开关的机械抖动次数进行了测量,测量结果表明:机械抖动次数是随机数,为0~11;对于复式按钮开关而言,前沿抖动次数一般小于后沿抖动次数;对单刀双掷开关而言,前沿抖动次数明显大于后沿抖动次数;人们在操作按钮开关时,要迅速果断且用力要恰当,这样有助于减小机械抖动次数。
為瞭研究電氣開關電接點的機械抖動次數,特彆是為瞭測量電接點的機械抖動次數,研製瞭基于微控製器的機械抖動次數測量繫統。論述瞭測量繫統的硬件設計和軟件設計,給齣瞭電路原理圖和程序流程框圖,以及關鍵程序源代碼。對輕觸按鈕開關、複式按鈕開關、單刀雙擲開關的機械抖動次數進行瞭測量,測量結果錶明:機械抖動次數是隨機數,為0~11;對于複式按鈕開關而言,前沿抖動次數一般小于後沿抖動次數;對單刀雙擲開關而言,前沿抖動次數明顯大于後沿抖動次數;人們在操作按鈕開關時,要迅速果斷且用力要恰噹,這樣有助于減小機械抖動次數。

In order to study the mechanical dithering number of electric switch contact, especial for measuring the mechanical dithering number of electric contact, a measurement system of the mechanical dithering number was de-signed based on MCU.This paper discussed the hardware design and software design of the measurement system, and provided circuit diagram and flow chart of program, as well as the key source code.For nudging button, com-pound button and SPDT switch, the mechanical dithering number was measured.The measurement results show that: the number of mechanical dither is random digit, it is 0 to 11; for compound button, front edge dithering number is usually less than back edge dithering number;for SPDT switch, front edge dithering number is obviously greater than back edge dithering number.When pressing the button switch, we need to operate it quickly and deci-sively and force it appropriately, which helps to reduce the mechanical dithering number.
