Firmware upgrading method, device, system and equipment and storage medium

The invention discloses a firmware upgrading method, device, system and equipment and a storage medium, and the method comprises the steps: receiving target version information of preset firmware sent by a server based on message middleware, the target version information being version information of the preset firmware newly pushed in the message middleware; determining whether the preset firmware needs to be upgraded or not according to the target version information and the current version information of the preset firmware; when it is determined that the preset firmware needs to be upgraded, obtaining target firmware sent by the server based on the message middleware; and performing firmware upgrading based on the target firmware. According to the technical scheme, the server side can pre-store the target version information and the target firmware in the message middleware, when the terminal is connected with the server side based on a network, firmware upgrading can be conducted on the terminal based on
