智慧庭院照明系统设计与实现

针对传统照明设备在智慧庭院场景应用性差、用途单一、无法提供优越的用户体验等缺陷，将物联网技术、脉冲宽度调制（PWM）调光技术、无线通信技术、云技术与手机APP相结合，设计出一种智慧庭院照明系统。该系统通过智能传感器件，对庭院照明设备进行实时监测控制，并将检测数据发送至物联网云平台和手机APP人机交互界面。测试结果表明，该系统可根据环境自动开关、调整照明方式，根据红外遥控器指令实现近距离控制，通过手机APP调光调色及选择照明方式。

Design and Implementation of Smart Courtyard Lighting System

To overcome the obvious weakness of traditional lighting equipment in the smart courtyard scene in applicability,multipility of use and excellence in user experience,a smart courtyard lighting system is designed using the technologies of internet of things(IoT),pulse width modulation(PWM) dimming,wireless communication,cloud and mobile APP.The system functions the real time monitor and control of the courtyard lighting equipment through intelligent sensor devices,and sends the detected data to the IoT cloud platform and the human computer interaction interface of the mobile APP.The test results show that the system can automatically switch and adjust the lighting mode according to the environment,realize short distance control according to the instructions of the infrared remote control,and adjust the light and color and select the lighting mode through the mobile phone APP.
