摘要
介绍了一种用于称重配料系统数据记录与处理的仪表。记录仪以内含ARM7处理器的M in iARM工控板为硬件核心,控制系统的运行。以称重传感器和A/D芯片ADS7805采集称重数据,液晶模块实时显示数据和控制信息,RS-232或RS-485电路实现与上位机的通信。采用F lash存储器和USB通信模块实现随时记录数据的功能。在详细介绍了记录仪的整体解决方案和硬件模块后,阐述了系统软件设计,软件以μC/OS-II操作系统为平台,设计了友好的人机界面,便于人工操作。该记录仪已经得到实现,应用结果表明:实用性强,功能可靠,可满足不同方面的需求。
This paper presented a new embedded system recorder for weighing control system gased on industrial control board, MiniARM. It took M2005-NU11 and μC/OS-Ⅱ as the hardware and software platform. The recorder has many functions, such as friendly GUI, abundant communication interfaces, data collecting and processing, display result on real-time, output of intelligent control, USB data storage. It provides a practical and reliable solution for proportioning weighing process control.
