Abstract

The invention discloses a discharge current recording device with trigger enabling and a fault recognition method, which are used for collecting pulse current of a pulse xenon lamp power supply and judging faults, and relates to the technical field of pulse power. The device comprises n paths of synchronous collection modules, a data processing module and a trigger communication module. Firstly, before a pulse xenon lamp power supply discharges, a trigger enable signal and experimental parameters are transmitted to a data processing module through a communication module, set current characteristics are calculated, and the trigger enable signal is relieved; then, the external trigger signal is sent to a pulse xenon lamp power supply to start discharging, Meanwhile, the external trigger signal starts data collection through a trigger communication module; and finally, the data processing module performs fault judgment on the acquired discharge data according to set current characteristics, and sends a result to an upper computer. According to the invention, the risk of false triggering caused by electromagnetic interference can be avoided, the discharge current is automatically interpreted based on the discharge current calculation and feature extraction of the nonlinear characteristics of the xenon lamp, and the efficiency of discharge current fault recognition can be greatly improved.
