中文摘要: 以AT89C52 单片机为核心研制出功能较为完善的即热式电热水器控制系统,该控制系统除了通常的控制加
热和保护外,还具有较强的智能,包括根据用户设定的温度自动控制加热管的工作,给出恒定温度的出水以及漏电
保护、相零检测和超温保护等功能。本文重点阐述了系统的工作原理、硬件构成、各部分的主要功能以及软件的结
构和实现。
Abstract:The paper introduces the basic design procedure of forming the control system of an electric water heater
with the single chip microcomputer. The control system of the electric tankless water heater with good function is
formed with the single chip microcomputer of AT89C52. Besides normal water temperature control in the electric water
heater and security control , the control system is featured with intelligent functions including producing fixed tempera2
ture water according user’s setting and creepage protection、detection of AC2L and AC2N、ultra2temperature protection
etc. The emphasis is laid on the principle of the control system , the structure and the functions of the hardware circuit
and software design methods.
