| 摘 要： | 针对目前在温度采集电路中的不足，结合一般温室大棚的功能需求，提出了一种基于FPGA的多点温度采集系统，本系统采用HX—EP2C8-V5型FPGA开发板作为研发平台，以DS18820作为温度传感器，利用FIR滤波器实现对采集信号的去噪处理，实现对温室大棚内多点温度采集，当测量温度超过设定范围时，可实现自动报警。文章详细分析了系统功能需求，结合QuartusⅡ给出了温度定期及按键选择采集模块、DS18820温度采集模块以及FIR滤波器的仿真结果。

| Abstract: | In view of the lack of temperature acquisition circuitry, and combined with the general functional requirements of greenhouses. This paper presents a multi-point temperature acquisition system based on FPGA.The system achieve multi-point temperature acquisition of the greenhouse and alarm automatically when the measured temperature exceeds the set range, which with HX-EP2C8-V5 FPGA development board as the platform, and DS18B20 as the temperature sensor, and FIR filter as the signal denoising. The article detailed analysis the functional requirements of the system, and show the simulation results of select the temperature acquisition module, DS 18B20 temperature acquisition module and the FIR filter with QuartusⅡ. |
