This test system simulates an OTA cloud server to create software upgrade tasks, performing functions such as software package detection, verification and distribution. It uses a signal shield to simulate various network conditions, including strong signal, weak signal and disconnection. In compliance with ISO 24089 and GB 44496 standards, the system invokes the HMI interface to graphically display the OTA workflow. It conducts comprehensive testing, including precondition checks for OTA upgrades, software flashing process testing, performance testing, stress testing, stability testing and failure mode testing.
