摘　　要：介绍了一种多参数温室灌溉智能测控系统的纯硬件实现。系统以Spartan-3A DSP FPGA为核心,对营养液混合过程中的营养液电导率和营养液酸碱度两个最重要的参数进行实时在线测量与控制,提出采用模糊逻辑控制技术来实现系统的有效控制,给出了基于Xilinx FPGA/CPLD开发平台和MATLAB/Simulink仿真环境进行DSP功能实现的方法和设计流程。实验仿真表明,系统设计紧凑、可靠,能够达到良好的控制效果。A new hardware implementation for multi -parameter measuring and controlling system used in greenhouse irrigation was introduced. Using Spartan - 3 A DSP FPGA as the kernel unit, this instrument was used for on - line measure and control of two important parameters of the nutrient admixture , which were Nutrient solution conductivity （EC）, Nutrient SoLution Ph. Fuzzy logical control technology was used to control the system. The design methods and flows of DSP core based Xilinx FPGA/CPLD development platform and MATLAB/Simulink simulation environment were also introduced. The simulation showed that this system designed in this paper has the advantage of simple system architecture, high - efficiency , and can achieve good efficiency of control.
