中文摘要：
矿用开关数据采集及保护回路大多由单片机实现。由于采样间隔对数据存储和处理能力有限，对开关的灵敏度造成影响，降低系统的可靠性和继电保护的速动性。文章介绍了S3C2440 ARM9为核心的装置在矿用动力智能开关保护中的应用，设计并研制含有保护、测量、控制、通讯等功能的矿用动力智能开关装置，并给出了相应的软硬件实现方案。
英文摘要：
Mine switch data acquisition and circuits＇ protection were conducted by MCU. The limitation of sampling interval of the data storage and processing power would reduce the sensitivity of the switch impact, then reduce the reliability of the system and relay protection speed. This paper introduced the application of design of Intelligent Protection and Measurement Equipment. With respect to mine switch - disconnector based on S3C24d-0ARM9 and many other func- tions such as protection, measurement, control and communication covered, it also introduced the realization of the project in software and hardware.
