摘要
提出以32位内嵌ARM核的LPC2210为微控制器的仪表总线转换的设计思路,设计了RS232、RS485、CAN、USB等总线与以太网的接口硬件电路以及基于μC/OS-Ⅱ的实时多任务软件流程。该总线转换装置解决了仪器仪表与以太网的数据传输,可实现对仪器仪表的远程控制和访问。
The design idea of bus conversion technology of instruments has been proposed, which is based on embedded micro-controller with a 32-bit ARM core （LPC2210）. In this paper it makes a detailed briefing on the RS233, RS485, CAN, USB and Ethernet interface hardware circuit design and real-time multi-task software process based on μC/OS - Ⅱ. The bus conversion technology of instruments solved data transmission between the instrumentation and Ethernet through existing computer networks. It also could achieve the remote control and visit for instrument.
