摘　　要：为实现智能化控制铝合金轮毂在半固态凝固区间快速凝固,设计一款ARM+DSP控制系统,通过实时获取当前模具温度及充型速度,预判铸件温度情况,从而控制冷却系统。通过ARM设定温度及压力参数,DSP计算和处理压力和温度数据,并根据反馈的数据,控制冷却系统中水冷和风冷的开启和持续时间,实现对铸件温度的精准控制,使低压铸造的轮毂在固液相凝固温度区间快速顺序凝固,获得较好的表面质量和机械性能,从而实现对连续低压铸造铝合金轮毂生产的智能化控制。To realize intelligent control to the rapid solidification of aluminum alloy wheel hub in the solid-liquid phase solidification temperature range,an ARM+DSP control system was designed to predict the temperature of the casting by obtaining the current mold temperature and filling speed in real time,thus to control the cooling system.The temperature and pressure parameters were set by ARM in the man-machine interface,and the pressure and temperature data were calculated and processed by DSP.According to the feedback data,the opening and duration of water cooling and air cooling in the cooling system could be regulated,then the accurate control of the casting temperature could be realized.Therefore,the wheel hub of low-pressure casting could solidify rapidly and sequentially in the solid-liquid phase solidification temperature range with better surface quality and mechanical properties.Thus,the intelligent control of the production of continuous low pressure casting aluminum alloy hub is realized.
