基于FPGA的温度采集系统设计+源程序+电路图

摘要温度是我们生活中接触最多的物理量之一，与我们的生活息息相关；温度也是产品设计和生产制造的重要参数之一，对产品的质量和性能有重要影响。因此，准确地测量温度变得至关重要。
本文采用先进的EDA(电子设计自动化)技术，利用QuartusⅡ工作平台，设计了一种新型的测温系统。本系统主要包括硬件和软件两部分：硬件是在ALTERA的DE2 Development and Education Board的基础上添加18B20构成的；软件由Verilog HDL语言分模块编写而成，主要有分频模块、测温模块、显示模块等。本系统充分利用了FPGA芯片功耗低、密度大、具有嵌入式阵列块和可重复编程的结构特点，因而具有体积小、价格低、功耗低、安全可靠、升级和文护方便。20898

Title Design of a Temperature-measuring System    Based on FPGA
Abstract
Temperature is one of the physical which we mostly contact with in our daily lives, closely related to our lives; temperature is one of the important parameters of industrial design and production, determine the quality and performance of products. Therefore, accurate measurement of the temperature becomes critical.
In this paper, advanced EDA (electronic design automation) technology,Quartus Ⅱ work platforms and Verilog HDL (super-high-speed integrated circuit HDL)are used to achieve the design of a temperature-measuring system. The system includes both hardware and software components: the hardware is based on the DE2 Development and Education Board of ALTERA on to add 18B20 constituted; software written in Verilog HDL language of the module, the main partakers frequency module, the module temperature display module. As the full advantage of the FPGA chip density, low power consumption, and structural characteristics can be reprogrammed with an embedded array block, and thus the system is small, low power, low cost, safe and reliable, maintenance and upgrades easy.
