摘　　要：为了提高高速条件下仪表重量数据传输的稳定与可靠性,文章提出了运用新塘Cortex-M0芯片NUC200与北京鼎实嵌入式总线桥模块相配合的方式,设计了一款从站称重仪表C9G,以便接入DP网络,与主站实现信息交互;仪表采用NUC200作为CPU控制器通过I/O口实现对总线桥模块读写、初始化等信号的控制,通过串口实现和总线桥之间Profibus数据的发送和接收;采用嵌入式接口板提供Profibus-DP/V0从站通信接口。In order to improve the stability and reliability of theinstrument weight data under the condition of high-speed transmission,this paper proposed that Cortex-M0 chip NUC200 ofXintangand Beijing Dingshi embedded bus bridge module can be used to design a slave weighing instrument C9G, which can access DP network, and interaction with master.The instrument adopts NUC200 as CPU controller through the I/O port to control the signal of initialization,reading and writing of the bus bridge module, and through the serial port to sending and receiving datawith theProfibus bus bridge. The instrument adoptsthe embedded interface board to provide the Profibus-DP/VO communication interface.
