根据管道全位置焊需要控制的参量多和实时性强的特点，选择分布式计算机控制系统作为整体控制方案，设计出主从机之间的串行通讯网络和各从机间的同步控制网络，并制定了统一的信息格式和通讯协议。考虑焊接现场干扰强的情况，采用数据个数、参数类别和异或数三重校验方式，确保多机通讯可靠，完全满足控制要求
According to the characteristics of pipeline full position welding, which need more control parameters and real-time performance, the distributed computer control system is selected as the overall control scheme, the serial communication network between master and slave and the synchronous control network between slave machines are designed, And developed a unified information format and communication protocol. Consider the case of strong welding site interference, using the number of data, parameter types and XOR triple counting method to ensure reliable multi-machine communication, fully meet the control requirements
