基于网络的管线全位置焊接控制系统
摘要：
一种基于网络的管线全位置焊接控制系统，设有主控单元(4)，主控单元(4)通过控制网络输出各个空间特征点的焊接参数，并通过控制网络与焊车系统(1)实现位置、速度和转矩等数据传输；同时，在两者之间传递配置参数、状态信息等非周期性数据；所有运动控制系统过程参数通过控制网络传递至主控单元(4)；焊车行走控制单元(11)插值计算出当前空间位置的焊接参数；焊接电源(3)计算出匹配的送丝速度并以该位置的焊接参数起弧焊接，以实现焊接工艺参数的连续变化。本发明结构简单，运行可靠；其实现了管线焊接过程的计算机集成控制；且通过控制网络实现了各子系统的协同控制，提高了焊接质量和焊接速度。
摘要（英）：

The invention discloses a network-based pipeline all-position welding control system, comprising a master control unit (4), wherein the master control unit (4) is used for outputting welding parameters of each spatial feature points by a control network, transmitting data, such as positions, speed, torque and the like by the control network and a welding tractor system, and simultaneously transmitting aperiodic data, such as, configuring parameters, state information and the like between the control network and the welding tractor system; all procedure parameters of a motion control system are transmitted to the master control unit (4) through the control network; a welding tractor traveling control unit (11) is used for performing interpolation calculation to obtain a welding parameter of a current spatial position; and a welding power supply (3) is used for calculating matched wire feeding speed and performing arc welding by using the welding parameter of the position so as to realize the continuous variation of the welding process parameters. The network-based pipeline all-position welding control system disclosed by the invention is simple in structure and reliable in operation, and can be used for realizing the computer-based integrated control over a pipeline welding process and realizing the cooperative control over all subsystems through the control network, and thus, the welding quality and the welding speed are increased.
