舞台自动控制系统设计及冗余技术研究

Design on Automatic Control System of Stage and Study on Redundant Technology

研究和开发冗余技术是提高控制系统可靠性的一条重要途经。为了执行某项特殊表演任务,确保整个表演过程中决不会因为任何意外停顿,首创使用两种相对独立的控制机制,即PLC和PCC机制,进行控制,克服传统部分冗余带来的弊病,从而实现各个方面真正的冗余,确保任何时候的任务可靠性。

It is an important way to improve the reliability of control system by developing redundant technology. In order to implement a performance task to ensure that the performance will not be stalled during the period of performance at all events. It was the first time to adopt two kinds relatively independent control mechanism ： the PLC and the PCC control in the world, which overcome the traditional shortcomings of some redundancy and realized ture redundancy, thus ensured a task reliability at any time.
