The open service capability of 5G has changed the industrial internet data service process. When migrating industrial businesses to 5G network, the coordination of cloud-based data processes and the conflict avoidance of networked services should be considered. Taking power industry for example, to ensure data reachability and availability, a data service model based on Petri Net is proposed for unified modeling and analysis of business temporal logic and network functions. Then, based on reachability graph, VIKOR orchestration scheme is adopted to ensure the deterministic process and execution time of multiple data from space-time dimension. Simulation results show that it can avoid data conflicts after migration and improve deployment efficiency. Field test of power 5G experimental network verifies that this method can guarantee transmission delay of 12. 03~ 18. 35 ms and delay jitter of 2. 75~ 5. 62 ms of the bearer layer, the completion time of 5. 96~ 6. 68 s for power remote control business, and the data quality has been improved to meet the operational performance requirements of the power telecommunication network.
