基于单片机的电气量监测系统设计
摘 要
当前我国经济的快速发展对电力提出了更高的要求，但是目前我国的电力能源不足，出现用电供不应求的状况，因而，如何有效地利用电、加强电力负荷的控制，就成为当前电力运行的迫切需要。电气量监测系统的设计，对电力运行有着十分重要的意义。在电力系统中，电压、电流、功率因数、必须随时检测。目前，我国大多数变电站仍然由人工在用电高峰时间用分体式模拟仪表检测这些量。为此，我们采用单片机技术,对各种电量实行科学监测和记录，利用单片机技术, 设计的电气量监测系统对电压、电流、功率等参数进行科学监测和记录，并能够实时显示测量值并记录越限值和越限时间，本文主要介绍检测系统的采样方法、硬件设计、软件设计, 并简述了系统的特点。
本文将精度高，动态性能好，工作频带宽的霍尔电压，电流传感器，与美国模拟数字公司（Analog）推出的单片高速12位逐次比较型转换器AD574，以及RS485通讯器件等设计了一套电气量采集与监控系统。
本文研究的基于MSC51的系统单片机电气量采集与监控系统具有结构紧凑，工作稳定可靠，使用方便，可扩展性强等特点，具有较大的推广是有价值。

Microcontroller-based monitoring system for electrical quantities
Abstract
At present, China's rapid economic development on a higher power requirements, but at present China's electricity shortage, electricity shortage situation occurs, therefore, how effective use of the power to strengthen the electricity load control, running on a current power urgent need. Electrical capacity monitoring system of the power running of great significance. In power system, voltage, current, power factor, must always be detected. At present, most of the substation is still in the peak time by the artificial split analog instrumentation with these quantities. To this end, we use chip technology, the implementation of various scientific monitoring and recording of electricity consumption, using chip technology, the design of the electrical volume monitoring system voltage, current, power and other parameters for scientific monitoring and recording, and real-time display and record measurements The more time limits and more restrictions, the paper introduces the detection system of sampling methods, hardware design, software design, and outlines the characteristics of the system.
This article high accuracy, good dynamic performance, the working frequency band of the Hall voltage and current sensors, and the American Analog Digital (Analog) introduced single-chip high-speed 12-bit successive comparison converter AD574, as well as RS485 and other communication devices designed a set of electrical quantities collection and monitoring system.
In this paper, the system microcontroller-based electrical quantities MSC51 acquisition and control system with a compact, stable, reliable, easy to use, scalable and so on, with great promotion is valuable.
