【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 problems in machine tool resource sharing, such as resource representation, storage and matching with machining task, a mechanism of machine tool resource sharing based on ontology is proposed. The ontology is used to describe machine tool resources semantically to enhance its human-machine readability. The distributed database HBase is used to store the machine tool ontology information, and the HBase table is designed for the purpose of efficient access. The storage and efficient query of the machine tool ontology information are realized. A machine tool resource query strategy based on machining task is proposed to realize the effective matching between machining task and shared resource. Under the condition of storing a large number of machine tool instances to database, the lathe list suitable for this task is obtained by submitting the task to the resource sharing platform. The results show that the machine tool ontology model, the resource information storage scheme and the resource query strategy can meet the requirements of resource sharing, and verify the feasibility and effectiveness of the sharing mechanism.
