Distributed fiber optic acoustic sensing signals are affected by environmental noise interference, fiber optic transmission limitations, and multitasking processing requirements in practical applications. To solve this problem, an adaptive task scheduling method based on full waveform inversion is proposed, aiming to improve the signal-to-noise ratio, optimize multi task scheduling processing, and thus enhance the overall performance of the sensing system. Using a full waveform inversion method based on an improved adjoint state source equation, direct full waveform inversion is performed on distributed fiber optic acoustic sensing signals. Using a constructed neural network to learn variable relationships. Based on the variable relationship, provide the remaining number of solutions for each subtask of the selected main task in the current migration stage, update the probability of selecting the migration task, adaptively and dynamically select the migration task, and achieve multi task scheduling. The performance of multi task scheduling was tested on the benchmark test function, and the development trend of fitness and dispersion evaluation results was relatively positive, with fitness exceeding 8 and dispersion below 0.3. It can be seen that this method can effectively handle the problem of low signal-to-noise ratio of sensing signals, improve the quality of multi task scheduling in distributed fiber optic acoustic sensing systems, and have a strong assisting effect on multi task scheduling in systems with low signal-to-noise ratio signals.
