AI Technical Summary

Problems solved by technology

[0004] The overall structure of the integrated energy system is complex, and the daily management, control, operation and maintenance of the integrated energy service terminal is still generally at a relatively primary stage, mainly for troubleshooting, equipment maintenance, equipment inspection, parameter setting, terminal self-test and self-recovery, and operating program update In these aspects, there is little research on how to reduce costs, improve energy efficiency, and reduce carbon emissions during operation.

With the rapid development of integrated energy services, the traditional operation and maintenance model has low efficiency, high cost, and high carbon emissions, and it is difficult to meet the needs of integrated energy operation and maintenance management and control.
