轨道交通装备（地铁技术）产业导航全球专利数据集

本数据通过制定总分检索策略从全球专利数据库中筛选轨道交通装备（地铁技术）产业专利数据数据，用过降噪清洗、数据合并、分类排序形成地铁用材料、地铁固定建筑物、地铁车辆本身结构、地铁供电系统、地铁通信信号系统、综合运营管理系统及车站设备、施工/造修设备7大技术分支、28个细分技术领域的方便查询检索的专利数据集。
地铁技术主要包地铁用材料、地铁固定建筑物、地铁车辆本身结构、地铁供电系统、地铁通信信号系统、综合运营管理系统及车站设备、施工/造修设备。经检索并合并申请号，同时排除不涉及具体技术方案的外观设计专利后，得到地铁技术的总数据共计11453条，其中中国2529件，海外8924件。

This dataset is constructed by screening patent data of the rail transit equipment (metro technology) industry from the global patent database via a well-formulated hierarchical retrieval strategy. Following denoising and cleaning, data merging, classification and sorting, the dataset is categorized into 7 major technical branches and 28 sub-technical fields, covering metro materials, metro fixed buildings, the structure of metro vehicles themselves, metro power supply systems, metro communication and signaling systems, integrated operation and management systems and station equipment, as well as construction and maintenance equipment, thus forming a readily queryable and retrievable patent dataset.

The scope of metro technology covers the aforementioned 7 major technical branches. After conducting retrieval, consolidating application numbers, and excluding design patents that do not involve specific technical solutions, the total valid patent dataset for metro technology amounts to 11,453 entries, including 2,529 from China and 8,924 from overseas.
