Multimodal Signal Acquisition and Synchronization System Utilizing Arc Faults Ignition

Currently, electrical malfunctions remain one of the primary concealed hazards associated with fire. A multimodal signal acquisition and synchronization system utilizing arc fault ignition was developed due to the challenges associated with simulating arc fault ignition and the relative scarcity of research in this field both domestically and internationally. The system adheres to the specifications of Arc Fault Detection Device GB/T31143–2014, establishes a arc faults simulation platform, utilizes cotton, wood chips, and paper scraps as ignition materials, and arranges diverse electrical load types to perform experiments under varying environmental conditions, thereby simulating actual low-voltage residential electricity scenarios.; The multimodal sensor collaborative acquisition solution and the multimodal signal time synchronization processing program enable the simultaneous acquisition and feature extraction of arc voltage, current, and multi-dimensional images, thereby enhancing the automation and precision of data processing significantly. The system offers dependable experimental data to facilitate comprehensive research on the dynamic evolution laws and the physical and chemical causes of arc fault ignition fires, thereby establishing a platform for the development of early arc fault ignition fire prevention technology.
