【摘要】 开发了一种基于嵌入式Linux的高压开关室SF₆气体在线监测系统;在该系统中,数据采集单元可动态加载与卸载;为了更准确的判断SF6气体及其分解物泄漏情况,提出了一种新的积分检测法。文中详细介绍了系统的总体结构与工作原理,阐述了各部分的具体设计方法。现场运行结果表明了嵌入式工控机加嵌入式Linux系统设计模式的有效性和实用性。更多还原

【Abstract】 A SF6 online monitoring system for circuit breaker,based on embedded Linux,embedded computer and PIC Microprogrammed Control Unit (MCU);is developed in dais paper.In the system,the Data Acquisition Units (DAU) can be mounted and unmounted online.A mote reliable strategy to detect the leakage of the SF6 gas and its decompositions is proposed.The overall structure of the system and the its working principle are given,and the detailed design for each part of the system is introduced.The Advantage of the embedded Linux is testified by field running results.更多还原
