基于单片机的智能漏电报警系统设计

摘要

以漏电保护技术为主要研究对象，设计了一款基于STC12C5410AD单片机的智能漏电报警系统。系统采用伟福E6000和KEIL C语言编写程序，将现场总线技术应用于电力系统的网络管理，将I2C总线技术应用于模块化电路设计，将32位单片机配合高集成度的可编程外围接口电路构成高精度的监测单元，实现了软件部分功能设计，并在实验过程中初步形成了样品。该系统抗干扰能力强，灵敏度高，可自动控制、自动报警，成本低。%Taking electric leakage protection technology for the main research object ,a kind of intelligent electric leakage a‐larm system based on STC12C5410AD singlechip microcomputer (SCM) is designed .The system uses Weifu E6000 and KEIL C language for programming ,applies field bus technology in network management on power system and I 2C bus technology in module circuit design .It also combines 32 bites SCM and high integrated programmable peripheral interface circuit to form a high‐precision monitoring unit which finally realizes function design on software and initially forms samples in process of experiment .This system has strong anti‐interference ability and high sensitivity as well as is provided with functions of au‐tomatic control and alarm .
