摘要: |
从差压铸造工艺原理出发,构建了由工控机、PLC、IPC系列工控板卡组成的液面加压控制系统。基于工控板卡的DLL技术,采用增量式PID算法,在MFC平台下编制了控制程序。现场调试结果表明,本文构建的控制系统能根据设定的工艺曲线控制电磁气动阀门的开闭及调节阀的开度大小,满足差压铸造浇注过程对实时性的要求。 |

Abstract: |
Pressure loading control system is the nucleus of counter pressure casting system. According to counter pressure casting principles, this article designed a pressure loading control system, which consisted of IPC, PLC and IPC cards. Based on DLL technology, the system was built up under MFC platform. Practice debugging results showed that the system can realize real time control and satisfy production requirements. |
