Security monitoring method, device, robot and storage medium

The invention discloses a security monitoring method, device, a robot and a storage medium. The security monitoring method comprises the steps of: collecting sound signals by the robot; extracting sound characteristic parameters, and performing event category first judgment through using a pre-trained sound recognition model; when the first judgment result is a first abnormal event, acquiring theorientation of a sound source relative to the robot and position information of the sound source in a preset map, and sending out a first alarm signal; acquiring a video of the positioning position; analyzing the content of the video, and carrying out event type second judgment through using a pre-trained video recognition model; and when a second judgment result is a second abnormal event, sending out a second alarm signal, and storing the information of the second abnormal event into an event list, wherein the sound recognition model and the video recognition model can be deployed in a blockchain.
