基于单片机电动阀门控制系统设计研究

Design and research of electric valve control systembased on single chip microcomputer

针对传统燃气阀控制方式的不足,提出了单片机结合电动执行机构的解决方案。该方案设计了一种用于手/电控制方式切换的离合结构,解决了传统阀门只能手动控制的问题。在此基础设计了电动阀门控制系统。该系统以步进电机为执行机构,BF7615BM44为主控模块,结合L6219驱动模块,UKS58K位置检测模块,触控按键输入模块和LED显示模块,实现阀门自动复位,挡位显示,蜂鸣警示功能。大大降低了燃气灶使用过程中忘记关火造成的风险。提高了燃气阀门的安全性能。

Aiming at the shortage of traditional gas valve control mode,a solution of single chip microcomputer combined with electric actuator is proposed.A clutch structure for manual/electric control mode switching is designed to solve the problem that traditional valves can only be controlled manually.On this basis,the electric valve control system is designed.Using the stepping motor as the actuator and BF7615BM44 as the main control module,combined with L6219 drive module,UKS58K position detection module,touch key input module and LED display module,the functions of automatic valve reset,gear display and buzzer warning are realized.It greatly reduces the risk caused by forgetting to turn off the fire when using the gas stove.The safety performance of the gas valve is improved.
