文档介绍：I 摘要本论文所设计的是一个基于 FPGA 的多功能数字温度控制器。本设计克服了传统数字温度计精度低的缺点,并且除了传统温度计的测量温度功能外还具有一定的控制功能, 能更好的对所测量的温度进行处理, 控制模块的加入让其比传统温度计具有更强的实用性。本设计采用 EDA 技术自上而下的设计思路,对系统的结构划分为温度采集模块、温度显示模块、输入数据对比模块, 输出控制模块。在 Quartus II软件下应用 VHDL 语言进行电路设计并仿真,根据仿真的结果。该方案能够较好的实现测温功能并且能对温度进行有效的控制。关键字: 温度控制; FPGA ; VHDL ; 北华航天工业学院毕业论文 II Abstract Designed by this paper isa multifunctional digital temperature controller based on FPGA. This design es the drawback of traditional digital thermometer low accuracy, and in addition to the traditional thermometer temperature function also has the certain control function, can better handle and on the measured temperature control module to join its than traditional thermometer has stronger practicability. This design adopts the top-down design EDA technology, the structure of system is divided into temperature acquisition module, display module, the input data contrast module, output control module. Under the Quartus II software circuit design and simulation using VHDL language, according to the result of simulation. The scheme can achieve a better temperature measurement function and can carry on the effective control of temperature.
