Data transmission method and device, electronic equipment and storage medium

Embodiments of the invention provide a data transmission method and device, electronic equipment and a storage medium. The method comprises the steps of obtaining an analysis result of a to-be-reported event and an identifier of a target image of the to-be-reported event; generating report information containing the analysis result and the identifier of the target image of the to-be-reported event; and sending the report information to a subscription end. According to the data transmission method provided by the embodiments of the invention, the identifier of the target image is used for replacing the target image, so that the data volume of report information can be greatly reduced, network congestion can be alleviated, and network time delays are reduced. In a data transmission process,such as alarming and data retrieval, picture data is changed into picture identifiers, and a subscription end can acquire pictures at any time through a network according to the identifiers. Through use of the identifiers, th
