基于单片机的鸡舍环境控制系统设计
摘 要
在现代农业中，鸡舍环境的控制对于鸡的健康和生产效率至关重要。然而，传统的环境控制方式常常需要人工干预，效率低下且容易出现误操作。为了解决这一问题，本论文设计了一款基于单片机STC89C52的鸡舍环境控制系统，旨在实现智能化的环境监测和控制，提升鸡舍管理效率和鸡的生产水平。
该系统具备多项功能：首先，通过DHT11温湿度传感器实时监测鸡舍的温度和湿度，当环境温度过高时自动启动通风设备，保障鸡的生活环境。其次，系统采用DS1302时钟模块同步时间，用户可以设定开灯的时间区，实现智能的照明控制。通过光敏电阻和ADC0832模块，系统能够监测光照值，当光照值低于设定的最小值且在开灯的时间区内时，系统将自动进行补光操作，确保鸡舍内的充足照明。用户可以通过按键对系统进行设置和控制，包括修正时间、设置温度上限值、设定光照最低值、调整开灯的时间区，以及手动控制通风和开灯，实现灵活的管理方式。同时，LCD1602显示屏将实时的温湿度、光照值和工作模式等信息直观地展示给用户，方便监控和操作。
综上所述，本次设计的基于单片机的鸡舍环境控制系统能够实现智能化的环境监测和控制，提升鸡舍管理的效率和鸡的生产水平。通过引入环境传感器，实现更精细化的控制策略，以及显示端实现监控和数据分析，从而更好地满足农业生产的需求。

Abstract
In modern agriculture, the control of chicken coop environment is crucial for the health and production efficiency of chickens. However, traditional methods of environmental control often require manual intervention, resulting in low efficiency and the potential for human errors. To address this issue, this paper presents a design of a chicken coop environment control system based on the STC89C52 microcontroller, aiming to achieve intelligent environmental monitoring and control, thereby enhancing the efficiency of chicken coop management and the production level of chickens.
The designed system incorporates several functionalities: Firstly, real-time monitoring of the temperature and humidity in the chicken coop is achieved through the DHT11 temperature and humidity sensor. When the environmental temperature and humidity exceed the set upper and lower limits, the system triggers audio-visual alarms. Additionally, in the case of high temperatures, the system automatically activates ventilation equipment to maintain a suitable living environment for the chickens. Secondly, the system employs the DS1302 real-time clock module to synchronize time. Users can set up a lighting time period, enabling intelligent lighting control. Thirdly, by utilizing a light-dependent resistor in conjunction with the ADC0832 module, the system can measure the light intensity. If the light intensity falls below the predefined minimum value and it is within the lighting time period, the system initiates supplementary lighting, ensuring adequate illumination inside the chicken coop.Users can interact with the system using buttons to adjust settings and control operations, including correcting time, setting temperature and humidity upper and lower limits, defining the minimum light intensity threshold, adjusting the lighting time period, as well as manually controlling ventilation and lighting, providing a flexible management approach. Simultaneously, the LCD1602 display screen presents real-time information such as temperature, humidity, light intensity, and operational modes, allowing users to monitor and manage effectively.
In conclusion, the proposed chicken coop environment control system, based on the STC89C52 microcontroller, accomplishes intelligent environmental monitoring and control, thereby enhancing chicken coop management efficiency and production quality. The integration of environmental sensors for precise control strategies, along with the display terminal for monitoring and data analysis, positions the system well to meet the evolving needs of agricultural production.
