摘 要: 针对现有智能照明系统人机界面可操作性差的问题,提出一种具备触控人机界面的智能照明控制器设计方案。智能照明控制器通过WiFi模块连接物联网云平台,可以实现手机端APP远程控制,调光调色,开关定时;同时,控制器上设计了独立的电容触控调光调色电路,可以脱离手机,现场手动触控调光调色,场景切换。文中以灯带作为照明光源,详细说明了远程控制与触控操作的驱动逻辑,实现远程智能管理和实时现场触控的有机结合。结果表明,智能照明控制器人机界面友好,显著改善了智能照明产品的实际体验。

Abstract: As the human?machine interface of the current intelligent lighting system has the problem of poor operability, a design scheme of the intelligent lighting controller with a touch?control human?machine interface is proposed. The intelligent lighting controller is connected to the cloud platform of Internet of Things (IoT) by means of the WiFi module, so as to realize remote control of the APP on the mobile phone terminal, brightness and color adjustment, and timing of switches. In the controller, an independent capacitive touch?control interface for brightness and color adjustment is designed to realize on?site finger touch control for brightness and color adjustment and scene switching without using a mobile phone. With the light strip taken as the illuminating light source, the drive logics of remote control and touch?control operation are described in detail, so as to realize organic combination of intelligent remote management and real?time on?site touch control. The results show that the intelligent lighting controller has a friendly human?machine interface, and can significantly improve the actual experience of the intelligent lighting product.

作为智能家居的一个子系统,智能照明技术将是未来强化家居中节能与健康管理等绿色功能的重要技术手段[1]。而LED固态照明非常方便实现智能控制[2],也是目前照明技术的主流。传统的基于DMX[3]总线及DALI[4]总线等有线控制技术,基于WiFi[5]、ZigBee[6]、蓝牙[7],RF?433MHz[8]等无线控制技术,以及基于有线总线协议的无线控制系统[9],在智能照明系统都有不同程度的应用研究。近几年快速发展的物联网技术,与智能照明应用结合迅速[10?11],并进一步融合语音控制技术[12],开始在云端应用人工智能识别语音[13],实现灯光情景控制。
现有的很多无线智能照明控制器设计功能单一,APP操作繁琐,协议兼容性差,在用户的实际生活中没有让用户体验到真正的方便快捷。……
