| Summary: | 碩士 === 國立中央大學 === 資訊工程學系碩士在職專班 === 100 === Due to the high reliability and standardization of Modbus protocol in industrial automation, this paper implant the Modbus protocol onto the 2.4G RF wireless communication and TCP/IP communication, and propose a three-tier wireless smart lighting network system. The bottom layer of this system is the wireless sensor/lighting network (WSLN) which can monitor the ambient’s temperature, humidity, and brightness and control the lighting. The mobile devices such as the smart phone or the tablet PC are situated at the upper layer, which are connected via TCP/IP for remote lighting control and monitoring. In the middle layer, we implement a Grafcet virtual machine (GVM) as the kernel of gateway, which provide an ubiquitous computing framework. The user can easily develop and update the event-driven smart lighting function from remote mobile devices. Finally, the experiments demonstrate the ambient monitoring and LED lamp lighting control by using the proposed smart lighting network, the results reveal that our system is applicable for rapid development of IoT(Internet of Things) based smart lighting in the digital home or industrial automation.
