| 摘 要： | 当智能水表受到强磁干扰时,可能会造成阀门的非正常打开或关闭。本文在脉冲电磁阀的单片机阀控脉冲输出端施加辅助比较器电路,通过控制比较器的使能端,在满足打开或关闭条件时比较器才能输出,进而大大降低了脉冲电磁阀非正常打开或关闭的概率。

| Abstract: | When the intelligent meter is subjected to strong magnetic interference,it may cause abnormal opening or closing of the valve.In this paper,an auxiliary comparator circuit is applied to the output terminal of the pulse solenoid valve controlled by a single chip computer.By controlling the enabling terminal of the comparator,the comparator can be output when the conditions of opening or closing are satisfied,thus greatly reducing the probability of abnormal opening or closing of the pulse solenoid valve. |
