The embodiment of the invention discloses a law enforcement officer post abnormal behavior monitoring method and device and a medium, belongs to the technical field of video data monitoring, and solves the problem that the post supervision accuracy of law enforcement officers is low in the prior art. Comprising the following steps: analyzing monitoring video data corresponding to a law enforcement place, and identifying a target law enforcement object in a video frame; in the monitoring video data, extracting a structured semantic element corresponding to the target law enforcement object; according to a preset law enforcement place type rule base, scene adaptation packaging is carried out on the structured semantic elements, and supervision semantic data frames are generated; and based on the continuously generated supervision semantic data frames, constructing an encrypted supervision semantic stream, and transmitting the encrypted supervision semantic stream to a cloud supervision analysis platform, so that the cloud supervision analysis platform matches the supervision semantic data frames with a preset reference law enforcement knowledge graph, and outputs a post monitoring result corresponding to the target law enforcement object according to a matching result.
