基于单片机的屋面雨水回收自动灌溉系统设计

Design of automatic irrigation system for roof rainwater collection based on single chip microcomputer

中国是一个干旱缺水严重的国家。水资源是一种有限而又不可替代的宝贵的资源,我国人均水资源量只有2300立方米,仅为世界平均水平的1/4,是全球13个人均水资源最贫乏的国家之一。目前我国的水资源分布具有时间、空间和地域分布不均衡的特征,而且多数水资源受到一定程度的环境污染与破坏,这对可国家的持续发展战略带来了严重影响。同时,大量水资源没有得到合理的利用,造成了一定程度的浪费,本屋面雨水回收自动灌溉系统利用屋面雨水收集装置过滤并收集雨水,利用单片机的可编程性,结合土壤湿度传感器、时钟模块、水位传感器、继电器等实现智能控制,从而实现自动喷灌,极大程度的利用了城市降雨,减少灌溉需要水资源和人力资源,相较于传统人力灌溉具有一定的优势。

China is a country with severe drought and water shortage. Water resources are a limited and irreplaceable valuable resource. The total amount of fresh water resources is 2 trillion and 800 billion cubic meters, less than 25% of the world average. It is one of the 13 most scarce water resources in the world. At present, the distribution of water resources in China is characterized by uneven distribution of time, space and area. Most of the water resources are polluted and destroyed by a certain extent, and there is a trend of increasing year by year. This has a serious impact on the national sustainable development strategy. At the same time, the reasonable utilization of water resources are not large, causing a certain degree of waste, roof rainwater collection device filtering and collecting rainwater using automatic irrigation system for recovery of roof rainwater, soil moisture sensor, combined with the use of single-chip clock module, water level sensor, relay to realize intelligent control, combined so as to realize the automatic sprinkler system, greatly the use of city rainfall, thereby reducing the irrigation needs of the water resources and human resources, compared with the traditional human irrigation has a great advantage.
