随着社会的发展,人们对生活的品质要求提高。由于城市楼房建设面积越来越多,却忽视了绿化带的建设,致使绿地面积越来越少,城市人们亲近自然的机会也相对减少。每天身处闹市的人们从内心深处对亲近大自然有一定浓厚的情感,人们渴望一种舒适宁静的绿色生活。种植盆栽有可以净化二氧化碳,吸收有害气体,使室内空气变得更加清新,也可以使人心情变得舒畅。近年来,盆栽智能浇水又成为人们谈论的新话题,比如说,在日常生活当中,人们总是忙于工作或者出差以及旅游,就会因此而无暇顾及盆栽的浇水工作。据调查表示,因为浇水问题致使花草生长有问题的高达80%以上。

针对无暇顾及盆栽浇水这一问题,本文设计了一种基于STM32单片机、传感器、NBIOT远程测控相结合的智能花卉灌溉系统。设计主要的内容包括硬件电路设计与软件设计。硬件设计包括底板电路的设计与制作、土壤湿度检测、光照强度检测模、雨水检测模块、智能灌溉以等部分。软件设计包括STM352引脚赋值、传感器软件设计以及参数设置等。该电路的工作原理是土壤温湿度传感器将盆栽中的湿度进行检测,光照强度检测模块检测当前环境的光照强度,雨水检测模块检测当前是否下雨,并且将采集的数据发送到单片机,单片机需要采集数据时,最后,单片机把采集到的湿度数据经过软件程序处理后送到OLED进行显示,同时也将采集的数据通过NBIOT模块传输到用户的手机,用户可以通过手机查看当前检测的数据和远程口罩遮雨棚、浇水。智能盆栽灌溉系统是通过单片机程序设计设置盆栽温湿度阈值、光照强度阈值,如果传感器检测到盆栽湿度低于阈值时,自动打开水泵对其进行灌溉,当土壤湿度超过阈值时,单片机会输出一个信号使水泵自动停止灌溉,当检测到下雨时,自动打开遮雨棚,检测到光照强度小于设置最小值,自动进行补光,当检测到光照强度大于设置的最大值,自动打开遮雨棚进行遮光。真正意义上做到“出差在外,花草无忧”。

基于STM32单片机的家庭花卉智能控制灌溉系统,目的在于提高智能浇水中的浇水质量以及节约水资源,通过对植物根部土壤湿度进行实时分析,结合系统中的各项数据指标,对浇水过程进行控制,达到精准控制。

Abstract

With the development of society, people’s requirements for the quality of life are improved. As the construction area of urban buildings is increasing, the construction of green belt is neglected, resulting in less and less green space, and the opportunities for urban people to get close to nature are also relatively reduced. Every day in the busy city people from the deep heart to close to nature has a strong emotion, people yearn for a comfortable and quiet green life. Planting potted plants can purify carbon dioxide, absorb harmful gases, make indoor air more fresh, but also make people feel comfortable.In recent years, potted intelligent watering has become a new topic that people talk about, for example, in daily life, people are always busy with work or business trips and travel, so they have no time to take into account the potted watering work. More than 80 percent of plants have trouble growing due to watering problems.

Aiming at the problem that there is no time to take potted watering into consideration, this paper designed an intelligent flower irrigation system based on STM32 single chip microcomputer, sensor and NBIOT remote measurement and control. The main content of the design includes hardware circuit design and software design. The hardware design includes the design and manufacture of the floor circuit, soil moisture detection, light intensity detection module, rain detection module, intelligent irrigation and so on. The software design includes STM352 pin assignment, sensor software design and parameter setting. The working principle of the circuit is that the soil temperature and humidity sensor detects the humidity in the pot, the light intensity detection module detects the light intensity of the current environment, the rain detection module detects whether it is raining, and sends the collected data to the microcontroller. When the microcontroller needs to collect data, finally, The microcontroller sends the collected humidity data to the OLED for display after processing the software program. At the same time, the collected data is transmitted to the user’s mobile phone through the NBIOT module, through which the user can view the current detection data and remote mask canopy and watering. Intelligent potted irrigation system is set up through the microcontroller programming potted threshold temperature and humidity, light intensity threshold, if the sensors detect the potted humidity is lower than the threshold, automatically open water pumps for irrigation, when soil moisture more than threshold, microcontroller will output a signal to the pump automatically stops irrigation, when detected when it rains, automatically open canopy, If the light intensity is less than the set minimum value, it will automatically fill the light. If the light intensity is greater than the set maximum value, it will automatically open the awning to block the light. In the real sense of “business trip out, flowers and plants without worry”.

The family flower intelligent control irrigation system based on STM32 single chip microcomputer aims to improve the quality of intelligent watering and save water resources. Through real-time analysis of the soil moisture of plant roots, combined with various data indicators in the system, the watering process is controlled to achieve accurate control.
