摘要
   隨著我國人民生活水平和質(zhì)量的提高，飼養(yǎng)觀賞魚的家庭日益增多。但是，大多數(shù)觀賞魚的飼養(yǎng)要求都比較高，尤其是對水的溫度，含氧量，渾濁度及光線都有特定要求，本次畢業(yè)設(shè)計是研究與制作大中型觀賞魚缸的水溫，渾濁度，含氧量，光線等相關(guān)物理量的自動控制，顯示裝置。
 該自控裝置以8位MCU89S52作為控制核心，通過溫度傳感器，溶氧傳感器，光敏傳感器分別對魚缸水的溫度，含氧量以及渾濁度進行檢測，采集的信號經(jīng)AD轉(zhuǎn)換器（ADC0809）轉(zhuǎn)換成8位數(shù)字信號，供單片機使用，為了從時間上對光線照明進行控制，選用了DS12C887時鐘芯片為系統(tǒng)提供時鐘基準。對魚缸水位的監(jiān)控采用了最簡單的浮子式液位開關(guān)，由于魚缸生態(tài)系統(tǒng)是一個大慣性系統(tǒng)，對被控量的實時性，精度要求都不高，因此以上器件以能滿足控制要求。本系統(tǒng)需要利用單片機控制220V交流電壓的各種設(shè)置，如魚缸增氧泵，過濾裝置等，為了簡化電路，單片機與功率設(shè)置之間采用固態(tài)繼電器進行隔離驅(qū)動。

The life of circulatory supervise and controls system research and creation

Abstract

   with the level quantity of our country family live,the feed to appreciate  fish is increasingly increase.But, most of appreciate fish's feeding request are too high, particularly the water temperature,the contain of the oxygen deal,muddy degree and ray all contain design of particular request, this graduate is study and create 'big and medium-sized' appreciate the fish tank's water temperature,the oxygen deal,and the ray etc.the related physics the auto that measure the control, and show the device.
   Should equip from the control core of 8 MCU89S52 conduct and actionses, pass the temperature to spread to feel the oxygen to spread , light to spread to feel the respectively to temperature of water fish tank, contain the oxygen to measure and the muddy degree of proceeds examination, the signal collecting was converted by AD( ADC0809) convert 8 arithmetic figure signal, provide the single slice the machine the usage, for illuminate to proceed the control to ray from timing, chose to use the DS12C887 clock the slice to provide the clock basis for system.Adopted to supervise and controling of fish tank water level simple of type liquid solid hour for switch, because of fish tank ecosystem system is a big and inertial system, rightly drive measuring.The accuracy requests all not high, therefore the above piece is to can satisfy the control request.This system the demand make use of the single slice the machine the control 220 V exchanges electric voltage of every kind of establish, if the fish tank increase the oxygen pump, and filter to equip the etc., for the sake of that the simplification electric circuit, machine and power of single slice establish adopt the to proceeds after the electric appliances the insulation to move.

Key phrase: oxygen deal; Water temperature control; The Solid state relay ; DS12C887; Fish tank ecosystem system
