摘　　要：为克服基于RS-485通信方式的监控系统受到节点数即工作站数目和通信距离限制,以及节点间不能彼此通信,且主从式的工作方式给安全生产监控的发展受到局限性等,提出CAN总线工作站的设想,分析以CAN总线工作站取代原有工作站的可行性,并详细说明工作站的软件实现原理。结果表明,基于CAN总线的工作站的设想是可行的。For conquering the problem that RS-485 workstation＇s node number and transport distance are restricted, as well as communicating among nodes is unable, what is the most important, the mode of principal and subordinate communicating bring about trouble for its developing on the watching and controlling of the safety work. Puts forward the idea of CAN bus workstation and analyzes the feasibility of changing the RS-485 workstation to CAN bus workstation, and shows the way of software in details. The result shows that the idea of workstation basied on CAN bus is feasible.
