摘  要
 在能源日趨緊張，環(huán)境保護(hù)日益受到重視的今天，脈沖燃燒技術(shù)的推廣應(yīng)用具有特別重要的意義，目前世界各國對脈沖燃燒的研究也越來越多。本文所設(shè)計的采用AT89S51單片機(jī)控制的脈沖燃燒熱水爐，對系統(tǒng)的穩(wěn)定運(yùn)行及合理利用硬件資源帶來滿意的效果。
 本文主要討論了以AT89S51單片機(jī)為核心的硬件電路設(shè)計和軟件程序的設(shè)計，通過傳感器對水溫水位等的檢測數(shù)據(jù)送至單片機(jī)，控制各個繼電器的開啟和關(guān)閉，并且通過LED實時顯示溫度。另外還有熄火檢測及報警電路，從而實現(xiàn)熱水爐的全自動管理：自動供氣、自動點火、自動進(jìn)水、出水溫度、水箱水位控制、水溫連續(xù)檢測及數(shù)字顯示；熄火時，能自行啟動的自保護(hù)功能和水溫超高、水位超限處理能力。使熱水爐在無人狀況下也能安全可靠的運(yùn)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.
