3D Dynamic Cinema Automatic Control System Design

摘要:

结合北京天文馆3D动感影院自动控制系统项目,设计并实现了一套3D动感影院自动控制系统,此系统由主控柜、OCC操作面板及控制箱组成；通过急停连锁及运动许可的双重保护实现了系统的安全模块；系统使用以太网,RS-232,RS-485实现控制设备之间的相互通信；实验证明,硬件布局合理,分布式PLC架构至iFix工控组态软件间的信号传输延迟在50 ms以下,本地数据库更新周期为0.5 s,保证了系统按步骤对3D影院中的的各类设备进行实时控制；在两周以内的72场放映中,系统正确率达100%。

Abstract:

According to Beijing planetarium 3D Motion Theater Automatic Control Systems project designed and implemented a 3D dynamic cinema automatic control system.This system consists of main cabinet, OCC operator panel and control box.Through emergency stop chain and sport license chain together to achieve the system security module.System also achieve mutual communication between control devices using the Ethernet, RS-232,RS485. Experiments show that the layout of the hardware is reasonable,The signal delay between distributed PLC architecture and iFix control configuration software in 50ms or less and the update cycle of local database is 0.5s so that able to achieve real-time control of various types of equipment in the 3D cinema.The 72 screenings within two weeks show that the correct rate of system up to 100%.
