Inventing Intelligence Switch
Base on Single-chip Microcomputer
Abstract
Switching power as connectivity components in power electronic
systems used very widely, Switches generally use the traditional
mechanical components to achieve the division circuit, in the course
of operating easily arc and hit Current. Intelligent Switch combines
the power electronics and computer technology as a new type of switch,
through automatic detection, Implementation Supervisory and system
protection functions.
This article introduces a high-performance 8 AVR
microcontroller Atmega8 to control the core, sensors and power
electronics components combining the intelligent switch hardware
and operating principle. And how detailed pull-AC DC maintained
through the AC voltage and current signals collection, calculated
AC voltage and current RMS, power frequency, periodicity, phase
angle, power factor, apparent power, active and reactive power of
the electricity and all other parameters. Through software
programming of the smart switch control to take corresponding flow,
undervoltage, overheating, leakage protection measures.
In this design, the sub-machine is provided by a combination which
consisting of keyboard and LCD module for debugging and setting
parameter at the scene. In addition, there is a RS-485 communication
interface ,so we can use the computer to centralized management and
monitoring the power by this system .
At last ,this text list some problem which the intelligent
application switching technology still requires further study.
