饮水机有两种翻译法,water dispenser 是指家庭用的饮水机,drinking fountain是指公共场所用的饮水机。 根据你的摘要,我暂且将你所指的饮水机是家庭用的饮水机。因此,我的翻译如下,希望能帮到你O(∩_∩)O~:So called Water Dispenser is a household product aimed to solve the problem of drinkingwater in our daily life. Because it can improve the quality of drinking water and our lifestyle , it is popular among the public. However, as the material living condition improves, people demands for higher performance. Along with its development, some problems of water dispenser start to come out. For example, "long boiling water" resulting from repeatedly heating might do harm to our physical health,and is also a waste of electricity. Currently, most of water dispensers sold in the market uses an entire hardware circuit, which may contain some limitations, like circuit complexity and mono-functioning. Because of inflexibleness and limitations of controlling, some water dispensers only have functions of heating and heat preservation. As a result, the author suggests that it is necessary to improve the control system of current water dispensers. The article mainly introduces the design process of using AT89C52 to make a simple and easy automatic control system of water dispensers, that is, using temperature sensor DS18B20 to measure the temperature and the liquid crystal display LCD1602 to display the Real-time temperature. Only the water temperature is below 70℃ will the water dispenser work and boil water. Under other temperature conditions, the automatic heating control system wil cut off the electricity, resulting in energy conservation. What's more, the lower limit of heating temperature can be adjusted by software. The new system uses AT89C52 as its cybernetics core, so the author focuses on the software programming method and how to use the software to achieve intelligent control of water dispensers. The new system is characterized by simple circuit structure, easy operation, less hardware requirement, lower costs, smaller power consumption and so on.Key Words : water dispenser, DS18B20, AT89C52
