摘　　要：为提高大型油库的液位测量系统中信号处理的精密性和实时性,设计了以CPLD为核心的准确、高速的四路油罐液位信号处理子系统,可同时完成四路油罐液位信号的滤波、计数和鉴相以及通信。详细描述了CPLD中各个模块的实现方法,用Verilog HDL实现各模块并在QuartusⅡ开发软件中进行仿真和分析。实验表明,该子系统能够实时高效准确的完成四路油罐液位信号的处理。Accurate high-speed four tank liquid level signal processing subsystem with CPLD as the core was designed to im-prove precision and real-time performance of the large oil level measurement signal processing subsystem, which can finish filte-ring,counting and phase detecting,and communication of four tank liquid level signal at the same time.The realization method of each module in the CPLD was described in detail by using Verilog HDL to realize each module and simulation and analysis were finished in the QuartusⅡ.The experimental results show that the subsystem can finish four tank liquid level signal processing effi-ciently and accurately.
