According to the characteristics of remote welding, including multiple parameters, real-time, and communication reliability of long wire transmitting, a distributing computer control scheme is adopted. A serial communication network between the master and the slavery computers is constructed. A synchro-control network among slavery computers is designed.Uniform message format and communication protocols are made. Considering intensive high-frequency noises at the welding zone, a quadruple check mode, including data sum check, parameter type check, welding parameters check and Exclusive OR ( XOR ) check, is adopted to assure the reliability of communication among multiple computers. Based on disturbing circuit,common circuit and sensitive circuit, the measures are brought forward to ensure the stabilization of communication network of remote arc welding by analyzing the wiring principle of anti-high-frequency interference of system bus, signal wires and shielding twisted-pair(STP) wires. The results provide the theoretical and practical references for the manufacture of remote welding robot and the quality of remote welding.
