摘　　要：针对大多数舞台布光控制系统存在的缺点,结合目前国内外舞台布光控制的技术,设计了一种接线简单、可靠性与稳定性较强,便于维护的新型舞台布光控制系统.该设计采用西门子S7-300系列PLC架构出分布式I/O控制系统,利用Profibus总线组建通讯网络,既简化了系统的控制线路,又提高了系统的数据传输速率,有效保障了系统的稳定性与可靠性.Aiming at shortcomings of most stage light control systems, combined with the current status quo of light control technology at home and abroad, a new system is devised. This system has predominance of simple wiring, high reliability and stability, easy to maintenance. The new system schemes distributed I/O control system utilizing Siemens PLC S7-300 series, and the communication network is built on Profibus bus. This does not simplify control circuit of the system, but also improves the data transmission rate, and guarantees effectively stability and reliability of the system.
