The invention relates to an energy management framework and method for rail transit energy storage, which relates to the energy management field of rail transit energy storage. The energy management framework comprises central-level controller, several station-level controllers, and several device-level controllers; among them, the central-level controller is wirelessly connected to all station-level controllers; a station-level controller is connected to a device-level controller by wired communication. The invention realizes the energy management of rail transit energy storage based on the above three-level energy management framework (center level, station level and device level structure).

Disclosed in the disclosure are a video playing detection method and apparatus. The video playing detection method includes: obtaining a playing count of a video at a detection pending moment; obtaining a quitting moment of the video, wherein the quitting moment is a video playing completion moment; judging whether the playing count of the video at the detection pending moment is zero; if the playing count of the video at the detection pending moment is zero, judging whether the detection pending moment is before the quitting moment; and if the detection pending moment is before the quitting moment, determining that video playing is not completed at the detection pending moment. The disclosure solves the problem in the related art where a video playing behavior cannot be accurately analyzed.
