The invention provides an information integration method and a information integration system for industrial production equipment. An equipment category is firstly established, the equipment category comprises a plurality of equipment classes, the equipment category is associated with an equipment body through equipment specification and model, on the basis of equipment classes, a plurality of classes of equipment category information adaptive to the classes are established for each class of equipment category, the equipment category information is associated with the equipment category through an equipment category number, in the meanwhile, the equipment body information is associated with the equipment body through an equipment number, and the equipment category information and the equipment body recording information are retrieved through the equipment body, so that the equipment information is effectively integrated, and the equipment, production and energy are uniformly managed, analysed and optimized; the equipment body information and the equipment category information are taken as the equipment information to be provided for the users with authority to view and use; in the meanwhile, the users with authority can update the equipment data at any moment and finally form a perfect and rich equipment information base meeting the requirements of the production enterprise.
