温室环境因子智能化控制系统的设计

Intelligent Greenhouse Environmental Factors Control System Design

植物生长需要特定的环境,特别是温度和湿度因子对植物的影响;当环境温度降低至某一低温或超过某一高温时,植物将停止生长,甚至腐烂、死亡;温室智能化控制系统中采用数字温度传感器DS18B20、电容式湿度传感器HS1101和STC89C54RD+单片机技术设计,自动检测温室内植物生长环境因子,通过执行单元驱动通风机、加热器、喷淋水泵、光照调节、CO2施放机构等设备,改变了传统温室依靠人工操作的缺点,实现了对植物生长环境的智能化控制。

Plant growth requires a specific environment, particularly temperature and humidity factors on plants. When the ambient temperature down to a low or exceeds a certain temperature, the plant will stop growing, or even decay and death. Using digital temperature sensor DS18B20, capacitive humidity sensor HS1101 and microcontroller technology STC89C54RD＋ design, the greenhouse intelligent control system tests environment for greenhouse plant growth factor automated. Through the implementation of unit--driven fan, heater, spray pumps, light regulation, CO2 cast bodies and other equipment, the greenhouse intelligent control system has changed the traditional shortcomings of greenhouse such as dependency on manual operation, to achieve intelligent control of plant growth environment.
