Article Preview

Conventionally, partial redundancy is applied at frail or crucial parts in most control system. As for the significant occasion of the Olympics Opening and Closing Ceremony, any fault of the control system may result in immeasurable losses. In this paper, we focus on redundancy policies and introduce the realizing of two different redundancy systems: the basic whole redundancy system, and the Hetero-type whole redundancy system, viz. two different control kernels (the PLC and its corresponding software and network) used in the same system. These two redundancy control systems are implemented at examination place and the National Stadium individually. These control systems set a successful example of the redundancy system implemented in mechanical control system at important occasions. By analyzing and comparing the reliability of the two redundancy systems, we get the results that the Hetero-type whole redundancy system has higher reliability than the basic whole redundancy system.
