摘　　要：本文研发的智能阳台养花系统以单片机STM32F103ZET6为核心,实时监测花卉所处环境光照强度值、土壤湿度值、风力值。通过与系统预先设定极限值对比,并对此采取相应的养护措施,从而实现自动化。由PWM调制红蓝光的脉冲宽度实现按比例补光;土壤湿度传感器获取的实时湿度值与比较器进行比较,通过继电器,触发水泵,实现自动浇水。联轴器,步进电机,升降台的螺旋杆三者相连,共同构成升降模块,小型直流有刷电机与三杯式旋转风杯组装而成的风速传感器相当于开关,自动控制升降台的高度。实验表明,该系统操作简单便捷,可实现花卉养护自动化。The intelligent balcony flower cultivation system developed in this paper takes single chip microcomputer STM32F103ZET6 as the core,and monitors the light intensity value,soil moisture value and wind value of flowers in real time.By comparing with the system preset limit value,and taking corresponding maintenance measures to achieve automation.The pulse width of PWM modulated red and blue light realizes proportional light compensation;the real-time humidity value obtained by soil moisture sensor is compared with the comparator,and the water pump is triggered by relay to realize automatic watering.Coupling,stepper motor and screw rod of lifting table are connected together to form lifting module.The wind speed sensor assembled by small DC brush motor and three cup rotating wind cup is equivalent to switch,which can automatically control the height of lifting table.The experiment shows that the system is easy to operate and can realize the automation of flower maintenance.
