家庭节水系统设计 PAGE PAGE IV PAGE I 基于STM32单片机的家庭节水系统设计 摘 要 在现在这个普遍缺水的大环境中，家庭生活中用水的循环使用，对水资源的节约有着深刻的影响。现有的解决方案中，节水系统一般都是针对工业和农业方面，专门针对家庭生活的节水系统很少，并且因为种种原因没有大规模的使用。大部分的家庭节水系统都是缺乏科技含量，通过靠人工将首次使用的洁净水储存下来，留作他用。本课题是采用单片机控制，利用传感器检测水位，由水泵驱动水流动的节水系统。 本课题的目标是根据水的循环再利用的指导思想，设计一套节水系统。遵循成本低廉，使用方便，运行安全的原则。将家庭中厨房、洗衣机等已经一次使用过的水进行检测，并且将水抽到存储水槽中进行暂时储存，可以用来对水质要求不高的一些用水环节进行水的二次利用，比如说冲洗马桶。因为厨房和洗衣机等的用水过程比较类似，所以本系统只设计一个用水环节。考虑到系统存在漏水的风险，这样就需要对存储水槽进行监测，并完成报警。因为在生活中不是全天都有人在家的，所以涉及到远距离通知的问题。本系统使用的方案是通过短信进行报警。 关键字：家庭节水；STM32单片机；二次利用 哈尔滨工程大学学士学位论文 家庭节水系统设计 PAGE PAGE III ABSTRACT In this environment now widespread shortage of water, the cycle of family life in water use, conservation of water resources has a profound impact. Existing solutions, water-saving systems are generally for industrial and agriculture, devoted to family life saving systems rarely, and for various reasons no large-scale use. Most of the families are relying on water-saving systems manpower, once used to store water down, reserved for other uses. This paper adopts MCU control, using sensors to detect water level, the water pump driving water flow water-saving systems. The goal of this paper is to use the thinking of recycled water, a water-saving system design. Lower compliance costs, the principle of easy to use. The family in the kitchen, washing machine has once used to detect water, and water is pumped to the storage tank to save, can be used for less demanding some of the water on the water quality aspects, such as flushing the toilet. Because the kitchen and washing machine water process is relatively similar, so the system is only part of the design of a water. Taking into account the risk of system leaks exist, so that the need for storage tank monitoring, and complete the alarm. Because in life there are people who are not at home all day, so it comes to the question of remote notification. Use of this system is an alarm via SMS.
