摘　　要：针对在传统检测领域应用很广的8位单片机系统由于其性能和资源的局限性,只能完成仪器仪表的基本功能,设计开发基于32位的ARM处理器和嵌入式Linux操作系统的电磁流量计。该设计采用TFT彩色液晶屏显示,通过JFFS2文件系统采用的方式进行数据存储,以TCP/IP协议为基础的工业以太网通讯方式,使得电磁流量计更具智能化、人性化和网络化。该设计所搭建的嵌入式系统开发平台也可推广应用到其他检测仪表的设计中,加速检测仪表的系统开发。8 b microcontroller systems used in the traditional test field,only can complete basic functions of the instrumentation due to its performance and resource limitations,an electromagnetic flowmeter of 32 b ARM-based processor and embedded Linux operating system is designed and developed.This design uses a TFT color LCD screen display,and adopts JFFS2 file system for data storage,makes electromagnetic flowmeter is more intelligent,humane and networking through TCP / IP protocol-based Ethernet communication.The design structure of the embedded system development platform can be applied to other instrumentation in the design of instrumentation to accelerate system development.
