摘要
近些年随着高档产品的包装大量采用转移烫金工艺,传统平压平烫金机难以满足生产的需要,因此,机加工企业开展圆压圆烫金机研制,其核心设备是加热系统。电加热器是一种在生活中常见的电力加热设备。电加热器内部存在一个温度传感器,根据其传达信来使电加热器温度自行变化,使温度均匀扩散加热表面。
如何在单片机的基础上设计烫金机的加热系统,设计中主要运用到了单片机相关知识和传感器(压力、温度、霍尔传感器等)方面的知识,而在测温过程中,使用单片机作为核心来操作,并通过数字接口的测温元件DS18B20来收索环境中的温度,且将实时温度在四位数码管上显示出来,主要设计了温度的测量系统、报警系统及转速方面,主要用到了霍尔传感器和单片机的结合及设计了软、硬件两个方面。
