摘要： 为解决机床资源共享中资源表述、存储及与加工任务匹配等关键问题, 提出基于本体的机床资源共享机制。 采用本体对机床资源进行语义化表述,增强其人机可读性。采用分布式数据库HBase对机床本体信息进行存储,以高效存取为目的设计HBase表格,实现对机床本体信息的存储及高效查询。提出基于加工任务的机床资源查询策略,实现加工任务与共享资源的有效匹配。在存储大量机床实例至数据库的条件下,以车削加工任务为例进行验证,通过提交该任务至该资源共享平台,获得适合该任务的车床列表。结果表明,建立的机床本体模型及提出的资源信息存储方案和资源查询策略能够满足资源共享的需求,验证共享机制的可行性和有效性。

Abstract: In order to solve the key problem which existed in resource expression, storage and processing task matching aspects of machine tool resource sharing, a sharing mechanism of machine tool resource based on ontology was given. Ontology was used to express machine tool in semantic, which increased the readability by both human and machine. Distributed database HBase was applied to store machine tool ontology, tables were well designed for the purpose of efficient access. A machine tool resource query mechanism based on machining task was proposed to realize effective matching between machining tasks and sharing resources. After storing mass machine tool instances in the data base, a case study was researched through submitting a turning task to the resourcing sharing platform and finally a list of suitable lathes were retrieved. The result shows that the machine tool resource storage and query mechanism based on ontology can meet the needs of resource sharing,and the feasibility and availability of sharing mechanism were also verified.

Key words: machine tool equipment, sharing, ontology model, distributed storage, query
