The invention provides a machine room remote panoramic monitoring method based on a virtual reality technology, and the method comprises the steps: building a panoramic image of a machine room throughemploying the panoramic image technology, carrying out the simulation of a machine room environment and all equipment in the machine room, and building a three-dimensional virtual machine room simulation model; respectively installing a plurality of panoramic cameras at a plurality of positions in the actual machine room, shooting the environment in the machine room by using the panoramic cameras, and splicing and fusing to generate a machine room panoramic image; according to the generated panoramic image of the machine room, remotely monitoring the environment of the machine room and the working state of each device in the machine room in a visual mode; and in the three-dimensional virtual machine room simulation model, providing visual display and visual management for display contentsof ports, connecting cables and panels of equipment so as to carry out IT operation and maintenance panoramic monitoring. The visual 3D machine room monitoring system provided by the invention provides friendly and efficient user experience for data display and information interaction, facilitates omnibearing management and operation, and improves the machine room management efficiency.
