摘要
在日常生活中,温度是最基本的环境参数。其检测与控制,对环境控制,生物生存与生长,工业的发展以及人类的生活都具有非常重要的意义。设计了基于FPGA的智能温度采集系统,主要阐述了该智能温度采集系统的硬件组成以及相应的接口电路设计。系统采用温度传感器LM75进行温度数据采集,以XILINX FPGA做控制器来实现温度检测,显示、传输等功能。该系统具有适应性较强、可以进行远距离传输、用LCD显示,精度高等优点。具有远距离温度信息监控、响应速度快、精度高、温度检测范围-55℃~125℃,精度可达到0.125℃等特点。
Temperature is the most basic environmental parameter for our life. It’s detection and control is critical important for environmental control, biological survival and growth, industrial development and human’s life. In this paper, an intelligent temperature acquisition system based on FPGA is designed. The hardware composition of the intelligent temperature acquisition system and the corresponding interface circuit design are mainly described. The temperature sensor LM75 is used as the temperature data acquisition, and Xilinx FPGA as main controller to realize temperature detection, display and transmission functions. The system has the advantages of strong adaptability, long distance transmission, LCD display and high precision. It has the characteristics of remote temperature monitoring, fast response, high accuracy, temperature detection range of-55~125℃, accuracy up to 0.125℃ and so on.
