摘要

 本設(shè)計的目的是為了讓水箱具有自動控制水位的能力。傳感器收集到信號后由放大電路傳遞到編碼器，產(chǎn)生控制電路的信號。當(dāng)水位超出設(shè)定范圍時能夠自動調(diào)整水位使其落在規(guī)定的范圍內(nèi)；水位低了就控制電機工作抽水，使水箱內(nèi)的水位上升，到達(dá)一定高度時電機停止抽水，從而達(dá)到不用人工專門去控制即可使水位保持在一定范圍的目的。另外還要使水箱具有顯示水位和超出一定范圍報警的功能。

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
