摘要
随着网络技术的成熟和普及,现代舞台控制技术逐渐向网络化方向发展,要求调光控制台可以接入以太网,以适应灯光网络的设计。在从数字调光系统到网络调光控制系统的过渡阶段,需要一种灯光控制系统既可以兼容DMX512协议又可以接入以太网来构建灯光控制网络。因此,本文采用Art-Net协议作为灯光网络通讯协议,同时使用STM32F407处理器搭建硬件平台,对实时操作系统μC/OS-Ⅲ进行研究并移植到Cortex-4平台,将嵌入式TCP/IP协议栈LwIP移植到μC/OS-Ⅲ,研究并设计了基于Art-Net协议的舞台灯光控制系统。实验结果表明该系统功能齐全、性能可靠、操作便捷,可以满足大型舞台灯光网络控制的需要。
With the maturity and popularization of network technique,the modern stage control system is developing towards network,so dimming control equipment should be connected to Ethernet to adapt to the design of stage lighting network. In the transition from digital dimming to network dimming control system,alighting control system needto be compatible with DMX512 and connected to Ethernet to construct stage lighting control network. In order to solve the problem,this paper uses Art-Net as the dimming data transmission protocol. The hardware platform was builtbased on the microprocessor STM32 F407. In the software designing,the real-time operating system μC/OS-Ⅲ wasanalyzed and transplanted.And the embedded TCP/IP stack LwIP was migrated to μC/OS-Ⅲ. Finally,the stage lighting control system based on Art-Net protocol was studied and designed. The experimental results show that the system has complete function,reliable performance and convenient operation. It can meet the needs of large-scale stage lighting network control.
