摘要
系统采用８９Ｃ５２单片计算机与ＤＳ１８２０一位总线数字温度传感器构成，可实现８台大型蒸汽湿热灭菌柜集中群控．系统为全数字化结构，有较高可靠性和稳定性，做到现场免调试运行．采用温度加权积分指标优化控制算法控制灭菌过程，减小了因加热蒸汽温度波动对灭菌效果的影响．
A computer control system of the steam boxes for disinfection consists of a microcomputer 89C52 and 1-wire digital thermometer DS1820,which can control 8 steam boxes.This system has high reliability and stability,and is used with simplification & convenience.The weighting function method is used to control the disinfecting process,and reduce the influence by temperature changes.
