摘  要
 在能源日趋紧张，环境保护日益受到重视的今天，脉冲燃烧技术的推广应用具有特别重要的意义，目前世界各国对脉冲燃烧的研究也越来越多。本文所设计的采用AT89S51单片机控制的脉冲燃烧热水炉，对系统的稳定运行及合理利用硬件资源带来满意的效果。
 本文主要讨论了以AT89S51单片机为核心的硬件电路设计和软件程序的设计，通过传感器对水温水位等的检测数据送至单片机，控制各个继电器的开启和关闭，并且通过LED实时显示温度。另外还有熄火检测及报警电路，从而实现热水炉的全自动管理：自动供气、自动点火、自动进水、出水温度、水箱水位控制、水温连续检测及数字显示；熄火时，能自行启动的自保护功能和水温超高、水位超限处理能力。使热水炉在无人状况下也能安全可靠的运行。

ABSTRACT
 Increasing tension in the energy, environmental protection, more and more attention today, the wide application of pulse combustion technology is of particular importance, the current world research on the pulse combustion more and more. This article is designed using AT89S51 MCU-controlled pulse combustion heater system for stable operation and the rational use of available resources, with satisfactory results.     This paper discusses the AT89S51 microcontroller core with hardware design and software design, through sensors such as temperature and water level test data sent to the microcontroller to control all relays open and close, and real-time through the LED display temperature. There are also flame detection and alarm circuits, in order to achieve fully automatic water heaters Management: Automatic gas, automatic ignition, automatic water, water temperature, water tank level control, temperature detection and continuous digital display; flame, can start their own self-protection and high water temperature, water level gauge processing. Making water heaters in the absence of conditions can be safe and reliable operation.
