Optimization of Measuring Points of Fire Suppression and Suppression Circuit Board Based on Global Sensitivity Analysis

Aiming at the problem of module-level and board-level fault diagnosis point selection for a certain type of fire suppression and explosion suppression system board, this paper uses the incentive and measurement point optimization method based on global sensitivity analysis to optimize the excitation and measuring points. The method uses Pspice software for simulation analysis, omitting the topology analysis and cumbersome calculation process of the sub-module circuit in the circuit board, and improving the selection efficiency of the measuring point. Considering the effects of component tolerance and parameter variation, the concept of global sensitivity is redefined, and the sensitivity of each measurement point under different excitation conditions is compared by global sensitivity analysis method, and the optimization of excitation and measurement points is completed. Point selection based on global sensitivity analysis is preferred.
