Fault analysis method, device and equipment of instrument control system and storage medium

The invention discloses a fault analysis method, device and equipment of an instrument control system and a storage medium, and belongs to the field of instrument control systems.Under the condition that the instrument control system is unstable, to-be-reconstructed sensing data causing the unstable state is cyclically reconstructed, and the fault analysis efficiency is improved. And analyzing that the simulation system of the instrument control system can recover the steady state based on the reconstructed sensing data, if the steady state is recovered within a certain cycle index, indicating that the unstable state is caused by the error of the sensing data, i.e., the sensing signal is invalid, and if the steady state cannot be recovered within a certain cycle index, indicating that the unstable state is caused by the error of the sensing data. If the instrument control system breaks down, correct sensing data cannot enable the instrument control system to recover the steady state, the reason for causing th
