水位控制器的设计

摘要

 本设计的目的是为了让水箱具有自动控制水位的能力。传感器收集到信号后由放大电路传递到编码器，产生控制电路的信号。当水位超出设定范围时能够自动调整水位使其落在规定的范围内；水位低了就控制电机工作抽水，使水箱内的水位上升，到达一定高度时电机停止抽水，从而达到不用人工专门去控制即可使水位保持在一定范围的目的。另外还要使水箱具有显示水位和超出一定范围报警的功能。
关键词：水位控制；报警；显示

Abstract
 This is designed to let water tank of water level with automatic control ability. Sensors to collect signal by amplifying circuit after passed to the encoder, produce control circuit signal. When the water beyond set range can automatically adjust the water level in its fall within the scope stipulated by; Water levels low control motor, that tank pumping water level rose when reach a certain height, the motor stops pumping, thus achieved without artificial specifically to control water can make the purpose of keeping within a certain range. Also make cistern display of water level and beyond a certain range of functions. Police
Keywords：Level control； alarm ；display
