摘要
随着各类热水器的缺点和不足日益明显,如能耗量大、预热时间长、存在安全隐患等,很多热水器已无法满足日常使用要求,因此设计一个稳定性好、安全系数高的即热式电热水器温度控制器系统的任务非常迫切。针对这些问题,本文提出了基于单片机的即热式电热水器温度控制器系统的设计,详细描述了系统硬件的设计和系统软件设计。本设计采用美国Atmel公司生产的AT89S51单片机作为主控芯片和数据存储器单元,结合外围的温度检测、水流检测、独立键盘输入、LED数码管显示、加热控制以及工作指示和报警等,使用C语言编写系统控制程序。经仿真和实验证明,该即热式电热水器温度控制系统的设计方法合理,系统具有控制方便、操作简单和灵活性大等优点,经过反复测试,系统能够稳定运行。

ABSTRACT
With the ings and inadequacies of various water heaters getting more obvious, for example, their high consumption, long heating time and potential security, many water heaters could not satisfy our daily needs any more. Therefore, it is very urgent to design a temperature controller system of an instant water heater with good stability and high security. To solve these problems, this essay proposes the design about temperature controller system of instant water heater based on MCU and describes designs of system hardware and system software in detail. The design adopts the AT89S51 SCM as the main control chip and the Data RAM made by the American Atmel Corporate, combines with the peripheral temperature detection, water detection, independent keyboard input, LED digital display, heating control, work instructions and alarm, and uses the C language system to control these programs. The results after simulating and experimenting show that it is reasonable to design the temperature controller system of instant water heater, because it has an advantage of convenient control, simple operation and Great flexibility. After testing again and again, it proves that the system can be operated stably.
