Forest fire fighting intelligent decision and command system and method based on unmanned aerial vehicle cluster and digital twinning

By generating a closed-loop mechanism for event identifiers and sequence numbers, the problem of duplicate and out-of-order forest fire event alarm messages under weak NB-IoT networks was solved, thus achieving the stability and consistency of the forest fire fighting command system and reducing the occurrence of duplicate and conflicting commands.

AI Technical Summary

Technical Problem

Under weak NB-IoT network conditions, the repeated and disordered forest fire alarm messages cause command and dispatch oscillations. Existing technologies lack effective closed-loop confirmation of state changes and constraint boundaries, resulting in frequent occurrences of repeated or conflicting commands.

Method used

By using an event identifier and sequence number closed-loop mechanism, the consistency of forest fire event alarm transmission is ensured. Event identifiers are generated using detection type codes, location grid codes, and local timestamps. Out-of-order convergence and idempotent task distribution are implemented on the platform side to ensure consistency in the status progression and command and dispatch of the same forest fire event.

Benefits of technology

In a weak network environment, it effectively suppresses duplicate and conflicting commands, reduces the probability of the same fire point being repeatedly judged as a new event, ensures the consistency between alarm transmission and command issuance, and reduces dispatch fluctuations.

Abstract

The application discloses a forest fire extinguishing intelligent decision and command system and method based on a UAV cluster and digital twinning, and particularly relates to the field of fire alarm and emergency command and dispatch, and comprises the following steps: reading a detection type code, a detection value digest, a location grid code and a local timestamp by a fire alarm terminal; calculating an event identifier by byte splicing of the detection type code, the location grid code and the local timestamp; and outputting an uplink message containing the event identifier and the detection value digest and used for UAV cluster task association; reading a local confirmation sequence number by the fire alarm terminal based on the event identifier, adding one to obtain a message sequence number, and writing the message sequence number into the uplink message and then sending the uplink message through NB-IoT. The state promotion boundary of the same fire point is written back and solidified through the closed loop of the event identifier and the message sequence number, and the platform side repeated elimination and out-of-order convergence are combined, so that the alarm uploading and the command issuing are relatively inhibited from causing dispatch shock caused by repeated and conflict commands under weak network out-of-order retransmission.
