摘  要:
提出一种基于VerilogHDL语言描述,FPGA实现的智能温室测控系统的软硬件设计方法。FPGA主控芯片采用Altera公司的EP2C8Q208C8芯片,结合ADC0809芯片完成数据采集,并在LCD图形液晶上显示采集到的信息,上位机界面采用VC++进行编程实现,上位机界面显示温室环境信息的实时值及其变化曲线。在温室控制方面,使用分段式控制,并且借助于串口继电器的无线模块实现无线控制。此种基于硬件电路的设计方法时钟频率高,响应及时,能够完成对温室内温湿度的采集、显示,以及对温室的控制。

摘  要:
This article proposed a hardware/software designing method with intelligent measuring and controlling system in greenhouse based on Verilog HDL and FPGA.This system is designed by using FPGA chip EP2C8Q208C8 produced by Altera Company combining with ADC0809 module to finish the data acquisition.Meanwhile,the acquired information will be displayed on LCD.The upper computer interface will be realized by programming with VC++.The upper computer interface can not only display the real-time environment information,but also show the changing curve of the acquired data.For controlling greenhouse,we apply sectional control method,and implement wireless control by using wireless module of serial relay.Based on hardware circuit,this designing method has a high clock frequency,can response timely,and is able to complete the acquisition and display of temperature and humidity in greenhouse,and thus to controll the greenhouse.
