基于单片机的电网数据采集系统的大学本科毕业论文

摘 要家庭和实验室中各种对电压要求比较高的电器和设备，在电压产生过高或者过低的波动时会产生误差或者损坏，此时必须对电压进行实时的在线监测。本系统采纳凌阳 SPCE061A 单片机作为核心控制器件来控制的电压采集系统。利用霍尔电压传感器来对 220 伏，50 赫兹的电压信号进行数据采集。经电压调理电路的调理和滤波器的滤波得到适合单片机的直流电压信号，进行采样信号的分析和处理，并与设定的基准值相比较，对其结果用 LED 实时输出。本设计涉及语言学、计算机科学、信号处理、模/数电转换等诸多领域，在煤矿、生产制造都可广泛运用，该技术有非常宽阔的应用前景。关键词：单片机，波动，监测，数据采集，滤波AbstractThis design is based on acquisition system with microprocessor controlled voltage. Home and laboratory on the voltage requirements of various electrical appliances and equipment relatively high, too high or too low in voltage fluctuations generated when errors or damaged, it is essential for real-time monitoring of voltage. The system uses Sunplus SPCE061A MCU as the core control device, using Hall voltage sensor on 220 volts, 50 Hz voltage signal data acquisition. The conditioning circuit filter conditioning and filtering by taking into account wave devices for single chip DC voltage signal, sampled signal analysis and processing, and with the reference value set by comparing its results with real-time LED output. The design involves linguistics, computer science, signal processing, analog / digital power conversion and many other fields, in coal mines, production can be widely used, the technology has very broad application prospects.Key word: SCM , volatility , monitoring , data collection , filtering 目录1 绪论....................................................................11.1 电压数据采集的现状..................................................11.2 电压数据采集的基本原理..............................................11.3 本系统...
