The invention discloses a virtual machine room visualization monitoring management system based on B/S architecture and a realization method. The virtual machine room visualization monitoring management system comprises a user service layer, a service logic layer, and an information data layer. The user service layer is constituted by a machine room scene display function module, a scene visualization roaming function module, a scene information query function module, a device state monitoring function module, and a scene warning positioning function module. An intermediate service layer is constituted by a Web application server, a user request processing module, and a scene information data interface module. The information data layer is constituted by an information database module, a database driving module, a machine room scene model file, an attribute data module, and a data information acquisition processing module. A visualization display function, a roaming function, a scene information query function, a device operation state monitoring function, and a scene warning positioning function of a machine room and a device of a Web terminal, and therefore the real-time monitoring of the state of the machine room and the state of the device is realized, and scene warning positioning function evaluation is realized.
