Design of a Smart Green Energy Management System Based on DMX512 Protocol

摘要

In this paper, a smart green energy management system based on DMX512 protocol that is established by United States Institute for Theatre Technology (USITT) is proposed. The end user can monitor and control the LED lamps and electric powers according to the information received from the sensors by means of the channels of DMX512. In addition, the different color lights including red, green, and blue lights can be achieved by means of the color-mixing methods of red, green, and blue LEDs based on photometry theory. As a matter of fact, there have been attracted much attention on the mobile devices in recent years. In the study, a mobile device with an Android platform is used to control the electric power and LED lamps according to the information received from the ZigBee module immediately. However, the smart green energy management system based on DMX512 protocol has some merits, such as in real-time control, easy operation, low cost, etc.
