摘　　要：为满足管道空间位置与焊接参数相匹配的智能全位置焊接系统的工艺要求,构建了以焊接电源通信模块为从站节点的主从式CAN(Controller Area Network)总线网络控制焊接系统.提出基于PC控制的服务数据对象(ADS)通信方式访问焊接电源对象词典,采用过程同步数据对象传输保证了数据传输实时性,同时使用基于视窗技术的组态软件可实现焊接过程的监视和数据的传输,实现了焊接电源CAN-open总线控制在管道全位置焊接系统的计算机集成.实验表明,该系统数据传输快速、稳定,可满足管道全位置焊接工艺要求.Digital welding equipment with network communication interface using bus-control is a prerequisite to realize intelligent,networked welding system.In older to satisfy the requirements of all-position welding process that the welding system could weld with mated welding parameters at any position,a master-slave CAN-bus network control welding system was constructed,consisting of a CAN-bus master and a welding power source based on CAN-open communication.By means of automation device specification based on PC control to deploy equipmental Objects Dictionary,the real-time and fast transmission of process data objects was ensured by using synchronous object transmission.Using configuration software based on window technology,welding process monitoring and data transmission were realized.Welding power source based on CAN-open was integrated in all-position pipeline welding system.The test result shows that the system runs stably, data transmission is reliable,meeting the requirements of all-position pipe welding.
