【摘要】：科学的控制植物生长环境在当今农业生产活动中显得尤为重要。目前国内大棚内的环境一般靠人工管理来调节农作物的生长,人工管理成本高且不能实时精准的考查大棚内环境。为了实现农作物生长的优质和生产的高效,开发出调节作物环境系统是非常有必要的。为了解决这个问题,本论文设计并实现了一种经济又实用型单点实时监测与控制大棚环境系统。该系统能够实时监测大棚内的光照强度和土壤湿度,并且能够根据监测到的情况判断当前环境是否在植物适宜生长环境内,从而作出相应决策。该系统有适宜农作物生长的光照和湿度的临界值,并且有按键检测调节临界值,能够针对不同作物的适宜环境设置临界值。本文涉及的工作主要有以下几个方面:(1)设计了监测和控制大棚环境系统整体的功能框架,选择STC89C52单片机为主控,光敏电阻和YL-69传感器采集数据传送到ADC0832处理,ADC0832将数据传送给单片机,单片机对相应负载作出开关决策,同时将数据传送到LCD1602显示。Altium designer为硬件开发工具,用于设计系统硬件电路图,实现元器件之间引脚的连接。Keil u Vision3为软件开发工具,用于编写软件程序,实现各部分的功能。(2)使用仿真工具PROTEUS为设计的硬件电路和软件进行仿真测试,验证设计系统的有效性。(3)对焊接好的电路进行断电、通电、录入程序调试。仿真验证了本系统的有效性。针对不同的作物,该系统可以快速准确的对大棚内的环境进行监测和控制,从而为作物提供适宜的生长环境。多点数据采集系统以及实现网络连接控制的上位机在进一步设计实现中。
[Abstract]:It is very important to control the environment of plant growth scientifically in the current agricultural production. At present, the domestic greenhouse environment generally depends on manual management to regulate the growth of crops, and the labor management cost is high and can not be accurately checked in real time. In order to realize the high quality of crop growth and the high efficiency of production, it is necessary to develop a crop environment regulation system. In order to solve this problem, this paper designs and implements an economical and practical single point real time monitoring and control system for greenhouse environment. The system can monitor the light intensity and soil moisture in the greenhouse in real time, and can judge whether the current environment is suitable for plant growth or not according to the monitoring conditions, and make the corresponding decision. The system has the critical value of light and humidity suitable for crop growth, and has the key to detect and adjust the critical value, which can set the critical value according to the suitable environment of different crops. The main work involved in this paper is as follows: (1) the function frame of monitoring and controlling greenhouse environment system is designed, and the STC89C52 microcontroller is selected as the main control. The data collected by photosensitive resistor and YL-69 sensor is transmitted to the ADC0832 processor ADC0832, which makes the switch decision to the corresponding load, and transmits the data to the LCD1602 display. Altium designer as the hardware development tool. It is used to design the hardware circuit diagram of the system and to realize the connection of pins between components. Keil u Vision3 is used as the software development tool to write the software program. The function of each part is realized. (2) the hardware circuit and software designed by PROTEUS are simulated and tested to verify the validity of the design system. (3) the welding circuit is cut off, electrified, input program is debugged. The effectiveness of the system is verified by simulation. For different crops, the system can monitor and control the environment in the greenhouse quickly and accurately, thus providing a suitable growth environment for crops. The multipoint data acquisition system and the upper computer which realizes the network connection control are further designed and implemented.
