Problems solved by technology

At present, the main method of TBOX power management testing is through manual testing. Since the entry and exit conditions and maintenance time of each power mode of TBOX are different, it takes a long time to switch between modes. It is difficult to quickly cover all use cases through manual testing. Complete all TBOX power management use cases
In addition, manual testing cannot accurately count the power consumption of TBOX in each mode, the switching time of each mode, and the duration of each mode
Therefore, manual testing of TBOX power management has the following disadvantages: complex test bench, extremely low efficiency, incomplete scene coverage, low test pressure, and insufficient test conclusion data

Description

technical field [0001] The invention belongs to the technical field of automatic testing of power management, and more specifically relates to a TBOX power management automatic testing equipment, system and method. Background technique [0002] TBOX is the basic terminal of vehicle communication. In addition to providing network for vehicles, it also needs to communicate with the background server of the car factory to realize functions such as remote vehicle control and vehicle condition query. In order to improve the response speed of remote vehicle control and vehicle condition inquiry, the power management of TBOX has several levels of power modes, such as: working mode, long connection mode, sleep mode, and shutdown. The power consumption of each mode of TBOX is different. In order to ensure that TBOX will not cause the vehicle to feed power, it is necessary to switch between the various power modes of TBOX according to the design. At present, the main method of TBOX p...
