基于FPGA的数据采集系统设计(论文12000字)
摘要：随着电力电子技术的飞速发展，温、湿度以及光照强度相关的数据采集系统也愈发稳定高效。本设计以FPGA作为核心芯片，DS18B20温度传感器、DHT11温湿度一体式数字传感器、AP3216C三合一光环境传感器作为主要的数据采集器件，将采集到的数据经过分析整理送LCD和数码管显示，该系统亦可实现报警功能。本系统运用模块化的设计思想，先独立设计各个模块，最终将其整合为一个整体。实验结果显示该系统能够实现对室内环境数据的采集，使人们实时掌握室内的环境指数。

Design of Data Acquisition System Based on FPGA
Abstract:With the rapid development of power electronics technology, data acquisition systems related to temperature, humidity and light intensity have become more stable and efficient. This design uses FPGA as the core chip, DS18B20 temperature sensor, DHT11 temperature and humidity integrated digital sensor, AP3216C three-in-one light environment sensor as the main data acquisition device, and the collected data is analyzed and sent to the LCD and digital tube display. The system can also implement an alarm function. The system uses modular design ideas, first independently designing each module, and finally integrating it into a whole. The experimental results show that the system can collect indoor environmental data and enable people to grasp the indoor environmental index in real time. [资料来源：www.THINK58.com]
