| 摘 要： | PLC已广泛应用于工业领域中，PLC的软件设计大多采用梯形图编程，文中设计实现了一种新的PLC编程语言——华P语言，并采用自顶向下逐句分析的方法设计了相应的华P语言到8051汇编语言的编译器。通过该编译器，可直接编译生成底层CPU需用的hex格式的机器码文件。最后通过对比梯形图指令，以实例分析得出华P语言的优势及应用的可行性。

| Abstract: | PLC is widely used in the industry domain,The PLC software design mostly uses the ladder chart programming. A kind of new PLC programming language is designed and realized in this article, using the top-down sentence by sentence analysis method to design the corresponding hua-P language for 8051 assembly language compiler. Through the compiler, it can directly generate the bi- nary file of hex format required by the bottom CPU. Finally through contrasting the ladder chart instruction, the superiority and the application feasibility of hua-P language are obtained by the example analysis. |
