| 摘 要： | 设计了一种基于STC12C5A32S2单片机的选矿给料控制系统。该系统采用PWM/DC转换技术对变频器进行频率设定(0～120Hz),进而控制选矿给料系统的给料量,并以较少的按键实现了参数设置,同时运用单片机内部自带的A/D把核子秤测量的给料量大小(4～20mA的电流信号)进行实时显示。系统具有可靠性高、易于操作等特点。

| Abstract: | Design of material feeding control system based on STC12C5A32S2 MCU is introduced in this paper.In the system,PWM technique to modulate frequency of transducer from 0 to 120Hz is utilized to control the capacity of the feeding system.Meanwhile,parameter is set by a few keys.The value of capacity of feeding system,which is measured by nucleus scale,can be displayed through the internal A/D conversion embedded in MCU.This system is characteristic of reliability and simplicity in operation. |
