摘要
施工现场数据量庞大,当前安全监控系统无法有效实现信息共享与重用,不能及时发现安全风险,整体性能较差。因此,设计了一种引入知识本体的施工现场安全监控系统,给出系统总体结构,其主要包括RFID无源标签、智能节点、网关、本体知识库和远程监控模块,介绍了系统运行过程。给出智能节点、网关的设计过程。依据ontology建模方法、施工现场安全风险相关本体、背景等建立施工现场安全风险本体知识库。对构建的本体知识库进行客观评价和主观评价,结果表明构建的本体知识库能够有效满足主观评价与客观评价的需求。将云架构系统和粗糙集系统作为对比进行性能测试,发现所设计系统平均上传速率很快,性能强。
The huge amount of data in the construction site,the current security monitoring system can not effectively achieve information sharing and reuse,can not find the security risk,the overall performance is poor. Therefore,the design of a knowledge ontology construction site safety monitoring system,the overall structure of the system are given,including the RFID passive tag,intelligent node,gateway,ontology knowledge base and remote monitoring module,introduces the running process of the system.The design process of intelligent node and gateway is given. According to the ontology modeling method,the construction site safety risk ontology,the background of the construction site safety risk ontology knowledge base. The objective evaluation and subjective evaluation are carried out for the constructed ontology knowledge base. The results show that the constructed ontology knowledge base can effectively meet the needs of subjective evaluation and objective evaluation. The performance of the cloud architecture system and rough set system is compared,and it is found that the average upload speed of the designed system is fast and the performance is strong.
