基于单片机的电量检测系统设计摘 要随着电力系统电量的日益扩大和电压运行等级的不断提高，传统的电量检测系统暴露出越来越多的缺点，难以满足现代电网向自动化、数字化进展的需要。本文首先概述了 WB 系列沟通电量传感器的工作原理和各项工作技术指标，并做了硬件系统的设计，包括控制电路、模块转换部分、键盘输入部分、LED 显示部分方面的设计。然后介绍了 ADC0809 和 74HC595 中电子接口的各项特性，同时对单元的结构原理和功能划分进行了分析和讨论，选择了合适的各种数据转换软件按。通过分析和讨论，提出了软件系统方面的设计方案，最关键的问题是 A/D 转换程序的设计、主程序和子程序的流程方案关键词 A/D 转换器 LED 显示器 ADC0809 74HC595 单片机POWER DETECTIO SYSTEM BESEDON SINGLE CHIP DESIGNABSTRACTWith the growing power system capacity and the increasing level voltage operation, the traditional amount of power detection system weaknesses exposed more and more difficult to meet the modern power grid to the automation, digital development. This paper outlines the WB series AC power sensor working principle and the work of technical indicators, and made the hardware system design, including control circuits, modules conversion component, keyboard part, LED showed that some aspects of the design. Then introduced the ADC0809 and the 74HC595 in the electronic interface properties, while the structural principles and functions of cell division was analyzed and studied, the suitable range of data conversion software by. Through analysis and research, the design of software systems, the most critical issue is A / D conversion process of design, the main program and subroutine program flow.KEYWORDS A/D conversion chip 74HC595SCM ADC0809 LED display chip目 录中文摘要...............................................................................................................................................I英文摘要.....................................
