Abstract： Based on LabVIEW platform, a distributed dynamic storage testing system is designed for measuring transient high-temperature signals of explosion field. Using a high-power semiconductor laser as heat source, a traceable dynamic calibration system is established to perform dynamic calibration of thermocouples. With quantum-behaved particle swam optimization (QPSO) algorithm on MATLAB platform, a model of dynamic compensation filter is established. It is used by LabVIEW that calls MATLAB Script nodes or COM components to accomplish the mixed programming of LabVIEW and MATLAB, further to compensate the temperature values of the thermocouples dynamically. The experimental results show that the technique that combines temperature measurement system with LabVIEW platform is applied well in testing the explosion temperature of thermobaric weaponry and makes the compensation values closer to the actual signals.
