摘　　要：GIS(Gas Insulated Switchgear)的运行环境复杂,容易产生各种电气故障,因此必须有一种可靠性高、抗干扰性强且具有防误操作的设备对其进行保护。根据这一要求给出了一种基于高性能的32位双CPU结构的新型GIS综合监控装置的研制方案与实现方式。装置的数字信号处理模块采用的是TMS320VC33高速处理器,控制与通信模块采用的是Sumsung公司的基于ARM7TMI的S3C44BOX,内嵌μCLinux操作系统,外带以太网控制器,能可靠地完成各项保护和控制功能,实现装置与装置、装置与计算机间的复杂逻辑联锁等逻辑功能。GIS （Gas Insulated Switchgear） runs in a complicated environment and it is so easy to be troubled. So something with high reliability and anti-jamming must be applied to protect it. A scheme of a new kind of GIS protection unit with double 32-bits CPU is of high performance is presented. One CPU is for digital signal process applies TMS320VC33 processor, the other CPU is for control and communication applies S3C44BOX of Sumsung which is based on ARM7TMI, and μ Clinux OS is embedded in it, a Ethernet controller is outside of it. The unit can achieve the fuction of protection, controlling and logic interlock between unit and ufiit or between unit and computer.
