It was put forward that a kind of beer ferment tanks temperature measurement & control system of intelligent network.This system chooses AD590L (the super ratio of quality to price) as temperature detector component,and using BCD-10 encoder(CC4028) and simulation switcher (CC4051) consists the temperature measurement & control network.The network is connected to single-chip microcomputer I/O with A/D D/A. The system realized temperature point of beer ferment tanks around of measuring and controlling.
