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
