基于ARM9现场控制器的冗余设计

Redundancy Design for the Field Controller Based on the ARM9 Technology

化工、能源等工业现场对数据采集、分析和控制的稳定性和实时性有很高的要求。介绍了以AT91RM9200控制芯片为平台,并结合Linux操作系统,采用硬件冗余设计具有很好实时性和稳定性的数据采集、分析、控制的系统,并说明了系统的组成、硬件设计原理以及软件设计方法。

For the need of the safety, the stability and real-time are very important for the data acquisition, analysis and control system which is widely used in the field of chemical, energy etc. The data acquisition, analysis and control system which is based on the ATglRM9200, Linux OS platform and hardware redundancy design is presented, and the structure of the system, hardware schematic and the method of the software design are introduced.
