【Abstract】 In this paper, the hardware platform of welding robot network communication were built, welding robot network communication model topology, network communication protocol and video transmission model were designed. The whole communication system was realized at VC++ 6.0 platform. What’s more, some tests to the system were done. In the end, wielding robot wide-area network communication preliminary study was done.First of all, welding robot network communication platform was built. Network conception was introduced to the traditional welding robot system in this paper. First, welding robot network communication model topology was designed, the hardware platform was realized. Then, the platform designed was access to the campus network.In the second place, welding robot communication protocol WRNCP in LAN and video real-time transmission model BPM in LAN based on UDP protocol was designed. In chapter three of this paper, firstly, C/S communication model, socket communication technology, multi-channel idea and multithreaded programming technology were introduced. Next, vide transmission method and video transmission control strategies were designed. Finally, the welding robot communication platform software interface was realized at VC++6.0 development platform with related technologies.In the third place, some tests to the welding robot communication system are done. The tests focus on the communication system delay, video transmission speed and protocol reliability. First, statistical analysis to the delay of TCP protocol, UDP protocol and WRNCP protocol is done. It can be found that data transmission delay of TCP protocol, UDP protocol and WRNCP protocol in LAN with zero load and in campus network, all hardly consistent with the normal law. Secondly, test and analysis to video process speed and transmission spend of the hole system were done, and propose that real-time is the most important indicator parameters in welding robot network communication system. In the end, the reliability tests of system have been done, and have given the analysis explanation to packet splicing of TCP protocol.Eventually, preliminary study and discuss on welding robot communication method in WAN were done. First, network address translation (NAT) technology, network maximum transmission unit (MTU) and so on is introduced, and the factors causing frame lost in WAN were analyzed. Next, the welding robot WAN communication protocol, video real time transmission method and video transmission control strategy are designed. Lastly, the welding robot WAN communication system software platform was realized at VC++6.0 development platform, and some tests to video transmission spend of the system in campus have been done.更多还原
