ZK-241电子程序快门的测光方法与曝光量控制

A Light-measuring Method and Automatic Exposure of ZK -241 Electronic Program Shutter

本文对ZK-241电子程序快门的传动机构、电路控制原理和工作时序图进行了系统的介绍,对它的瞬时测光方法及曝光量控制进行了深入的理论分析,建立了闭封控制数学模型。该程序快门控制系统,构思新颖,对于其他同类快门的设计,有一定参考价值。

This paper introduces the gear-drive mechanism, electronic circuit control and time-Programming figure for ZK-241 electronic program shutter. Detail analyses theoretically are given to the instantaneous light-measuring method and automatic exposure which lead to an establishment of a mathimatical model of closed-loop control.The design conception of the electronic program shutter control system is ingeniously conceived, which will be the reference in the shutter designs.
