摘　　要：通过对当前衡器产品的调研,并以现代衡器行业发展的需求为依据,提出了一种智能衡器的整体设计方案.以ARMll S3C6410为核心处理器,Linux嵌入式系统为智能衡器提供控制系统,使用Linux Qt完成了控制程序及人机界面.采用WIFI通信技术达到系统远程通信及数据采集的目的,通过STM32芯片设计了USB键盘,并采用热敏打印机来打印交易记录.在传统衡器的基础上,加入了网络和数据库技术,使得衡器更具智能化.测试结果表明,系统稳定可靠、易于操作,达到了设计目标.Through the investigation on the current weighing products,with the demand on development of modern weighing industry as the basis,this paper proposed a novel design of smart weighing apparatus. It takes ARM11S3C6410 as the MCU and embedded Linux as control system,and uses Linux and Qt to complete the control procedures and man-machine interface. It aloe uses WIFI communication technology to complete the remote communication and data acquisition. We use the STM32 chip to design the USB keyboard and use thermal printer to print transaction records. The approach based on the traditional weighing apparatus Joined with the network and data-base technology, makes the weighing apparatus more intelligent. Test results show that the system is stable, reliable and easy to operate.
