详细介绍了一种基于Altera公司Cyclone系列的EP1C3T144C8处理器和DS18B20数字温度传感器来进行温度测量与监控系统的设计,其中包括处理器与温度传感器接口电路的设计,以及温度信息采集和数据传输的软件设计,从而实现PC机和数码管同时对温度监控的目的。DS18B20是单总线器件,与FPGA组成的温度监控系统具有线路简单,体积小等特点,实际应用十分方便。
The design of a temperature measurement and monitoring system based on Altera Cyclone series EP1C3T144C8 processor and DS18B20 digital temperature sensor is introduced in detail, including the design of interface circuit between processor and temperature sensor, software of temperature information acquisition and data transmission Design, in order to achieve the purpose of temperature monitoring PC and digital control at the same time. DS18B20 is a single bus device, and FPGA temperature monitoring system with a simple line, small size and other characteristics, the practical application is very convenient.
