新型工矿用液位自动控制系统的设计与研究

New Design and Research of Liquid Level Automatic Control System for Mining and Mining

设计一种新的液位控制系统,利用2个与非门组成逻辑鉴别电路和正反馈记忆电路,通过调节高液位开关以及低液位开关两点之间的距离,便可调节所需保持的液面的高低范围,液面的调节空间为一个有限范围,而不是一个点,并且采用音叉式液位控制开关作为液面采样,该系统适用范围极广,可以应用于众多条件极其恶劣的工作场所。

Design a new liquid level control technology, using two nor gate logic discrimination circuit and memory circuit of positive feedback, through regulating the high liquid level switch and a low liquid level switch between two points distance can be adjusted by the need to maintain the level of high or low range, level of adjustment for a limited range, and is not a point, and the tuning fork type liquid level control switch as the liquid level sampling, the system scope very wide can be used in many conditions is extremely poor in the workplace.
