CPLD/FPGA在液体混合搅拌设备中的应用

The application of CPLD/FPGA in controlling the liquid mixer

CPLD/FPGA是一种可在线编程的大规模数字器件。利用一片在线可编程器件代替PLC(可编程序控制器),完成了对液体混合搅拌设备的控制,并给出了用在线可编程器件CPLD组成的、VHDL语言实现的控制电路设计和程序。

The programmable logic controller can be replaced by a piece of online programmable element to fulfill the task of automatic control of the liquid mixer. The paper offers the design and program of the controlling circuit composed with CPLD, and realized with VHDL language.
