A wearable, integrated vehicular temperature and vibration testing system has been devised to streamline equipment setup processes during vehicle testing, thereby bolstering testing efficiency. The system′s testing nodes, governed primarily by STM32 microcontrollers, are affixed using magnetic suction mechanisms. Leveraging a multifunctional adapter developed for the purpose, synchronization and concurrent configuration of diverse testing nodes are achievable, ensuring operation within a unified temporal framework. Data interchange with the host computer is facilitated through USB flash drive connectivity, facilitating seamless retrieval of test data. Furthermore, the multifunctional adapter offers ancillary functionalities such as charging, parameter configuration, data retrieval, and storage, augmenting the overall efficacy of the equipment. Extensive experimentation encompassing laboratory validation and real-world vehicular trials attests to the system′s convenient and dependable installation modality, markedly curtailing equipment setup durations. The testing system exhibits vibration acquisition accuracy within a relative error margin of 1%, while temperature acquisition errors are confined within ±0.1 ℃. Synchronization time discrepancies among multiple devices are constrained to the microsecond level. This system adeptly captures and archives temperature and vibration data pertinent to vehicular operations, effectively catering to the exigencies of operational state parameter acquisition for vehicles.
