In order to reduce operating costs and fulfill social responsibilities, enterprises and researchers in the field of rail transit need to study more efficient energy-saving technologies. Patent is one of the important ways to obtain information and knowledge related to technological innovation, but most of the existing patent analysis systems are statistical analysis of external patent information, and the results are not intuitive enough, which is not conducive to more in-depth mining of patent information. This paper introduces knowledge mapping related technologies to deconstruct and organize patent information to support scalable patent query and analysis requirements.
