煤矿井下监控系统在线检测技术利用ARM9系列处理器,采用三星公司的S3C2440为主控制器,设计嵌入式的数据采集系统。以S3C2440为核心,以FPGA、以太网控制器DM9000、LCD触摸液晶屏、SD卡、USB总线做为辅助来实现系统硬件外设,数据采集部分利用可变增益放大器和基本放大电路通过A/D转换芯片完成。软件实现了Linux系统在开发平台上的内核移植,设计出数据采集和数据存储程序。
Mine underground monitoring system online detection technology using ARM9 series processors, using Samsung’s S3C2440-based controller, the design of embedded data acquisition system. S3C2440 as the core, FPGA, Ethernet controller DM9000, LCD touch LCD, SD card, USB bus as an auxiliary system hardware peripherals, data acquisition part of the variable gain amplifier and the basic amplification circuit through the A / D Conversion chip to complete. The software implements the Linux kernel transplantation on the development platform and designs data acquisition and data storage procedures.
