The invention discloses a vehicle sensing information processing method and device and electronic equipment. The method relates to the field of automatic driving, and comprises the following steps: acquiring perception information acquired by an automatic driving vehicle; dividing a preset space corresponding to the sensing information according to a preset direction to obtain a plurality of first grids, the plurality of first grids being non-uniformly distributed in the preset space; and on the basis of the sub-perception information corresponding to the plurality of first grids, obstacle identification is carried out on the perception information to obtain an identification result, and the identification result is used for representing at least one of whether an obstacle exists in the preset space, the semantic category of the existing obstacle and the position of the existing obstacle. According to the method and the device, the technical problem of relatively high computing resource consumption caused by performing high-precision processing on the sensing information in related technologies is solved.

The application relates to a defrosting system and a refrigerator, the defrosting system comprising a heating module, a heat exchange module, a detection module and a control module; the heat exchange module comprises a heat exchange pipeline and a damper, the heat exchange pipeline comprises a first air vent and a second air vent, the first air vent is arranged in an evaporator chamber, the second air vent is arranged in a compressor chamber, and the damper is arranged in the heat exchange pipeline; the heating module comprises a passive heating device, the passive heating device is arranged on the evaporator; the detection module is used for detecting the frost thickness of the evaporator; the control module is configured to control the refrigerator to enter a defrosting mode when the frost thickness of the evaporator is greater than or equal to a frost thickness threshold value; in the defrosting mode, the damper is opened, the compressor chamber is communicated with the evaporator chamber, and the evaporator is heated by the heat stored by the passive heating device and the heat in the compressor chamber. Through the application, the problem of large energy consumption of the traditional defrosting mode is solved.
