基于单片机电热水器水温水位控制系统设计 摘 要 伴随人们生活水平提升，各种热水器使用已相当普及。与之相配套控制仪也相继问世。然而，现在市场上各种热水器控制电路还与理想要求相差甚远。所以我设计了新型热水器水温水位控制系统来满足于当今需求，该热水器智能控制系统主要由80C51 单片机控制、DS18B20 温度传感器、独立键盘、LED 数码管和报警系统组成。该系统能测量并显示水温、设置水温范围，若水温不处于所设置水温范围则报警，同时还能对水位进行设置及加水，先设置好需要加水水位段数，单片机会依照这个数进行推断是否加水。经过软硬件调试使以上所述功效都能正常实现。 此次设计是对水温水位控制系统智能化改进，实行单片机对其水温水位参数进行控制，提升了电器工作稳定性，同时引进了数字传感器对水温进行数据采集，这么也就提升了系统控制精度，以其本身控制精度高、稳定性好和成本低独特优点在今后将会由广泛有用价值，其基于单片机改进方法也具用广泛应用意义。 关键词：单片机；DS18B20；水温水位控制 Electric Water Heater Water Temperature-Level Control System Based on SCM Abstract With the improvement of people's living standard, the use of various water heater is popular. Control apparatus and the matched field. However, the current market on the var water heater control circuit and the ideal requirements differ very far.So i design a new water heater water level controlsystem to meet the semand inowdays. The design of solar water heaters intelligent control system is mainly composed of single-chip80C51,DS18B20 temperature sensor,an independent keyboard ,LED and alarm system.The system can measure and display water temperature ,set the range of water temperature,of the water temperatu not in the range of setting temperature is alarming.At the same time,you can set the wateand add water,first,need to set up the water level above the water,single-chip will determine whether add the water or not according to the number.Through hardware and software debugging,the above f...
