Research and Design of Grain Drying Distributed Controlling System Based on CAN Bus
摘要
Abstract
A grain drying distributed controlling system based on CAN Bus is put forward according to the present dry controlling system .The upper computer adopted the EPCS-500 embedded engineering machine , making full use of con-figuration software to develop the upper computer interface .While for the lower computer , the P83 C591 SCM with CAN Bus is used as nodes of each intelligent controllers , detecting the grain moisture content with the use of the capacitance method and detecting the drying temperature with the use of the DS 18 B20 which is called the single bus digital tempera-ture sensor chip .It has been proved that this distributed grain drying controlling system is accuracy controlled .It can conveniently adjust the control parameters and the drying technology .With the less lines , it can be mended conveniently . It has high accuracy and is strong enough to withstand the interference .With low price it can fulfill the demanding of real-time measurement .关键词
