This paper presents a method of improving on frame & horizontal synchronization in laser phototypesetter, by using singal - chip computer system to detect real - time frequency deviation and adjust film transmission speed
摘要提出了一種在激光照排機電控系統中,利用單晶片微機對轉鏡掃描光柵頻率信號的暫態波動量進行檢測、提取,並以此實時校正系統輸片速度,實現場掃描對行掃描的跟蹤、補償,從而提高行、場掃描同步精度的方案。Abstract : this paper proposes an self - adaptive speed - accommodating control circuit, which can get the speed - error, and can test the change of frequency of feedback signals of the single phase ac tacho generator through self comparing and automatically corrects the speed
文摘:文章介紹了通過自比較來檢測錄音機主導軸單相永磁交流測速發電機反饋信號的頻率變化,從而獲得速度誤差,並自動校正轉速的一種自適應速度調節控制電路。Firstly, the outputs of the infrared sensors are analog signals, which can be disturbed by noise in optical path and circuit. it has a low precision and stability when using traditional signal processing method, so in this paper a novel spectrum analysis method based on the fft is discussed and some methods are taken to rectify errors from the limitation of the fft
首先,由於紅外傳感器的光電轉換在光路和電路中都會受到噪聲的影響,針對採用傳統信號處理方法帶來的測量精度低、可靠性差這一問題,本文採用快速傅立葉變換和周期圖法的經典譜分析方法對傳感器信號進行處理,並對產生的誤差進行了分析和校正。
