| Abstract: | redundancy control has important meanings for reliability in the automated industry control system based on PLC (Programmable Logic Controller). from the redundancy collocate of cold standby, hot standby, vote system, the resolve method is offered for some working condition of high reliability in the text, a parallel redundancy's design which is used widely is analyzed and a effective redundancy's design is putted forward. |
