The system adopts the real-time database and relationaldatabase to collect the scattered structured data, such as evidence information of offshoreoil and gas production facilities personnel, on-site hidden danger information andincident investigation report. Then a unified secure data center platform is established forevery operating area and production site, and the critical safety data of production sitescan be centrally managed. This system has the functions of lawful real-time supervisionof personnel qualification, online supervision and trend analysis of hidden dangers, andcentralized management and sharing of incident investigation report. By applying theMES system in security management, the process of safety service becomes standardizedand modularized, the management process becomes normalized, and the efficiency andeffect of overall management is improved.展开更多
在快速更迭、趋势驱动的鞋服产业链中,供需结构正从传统的大批量规模化制造向柔性化、小单快返与定制化服务形态加速演变。以往依赖人工扫码、纸质流转卡和经验管理的生产调度方式,已难以在更短交付周期、更高库存周转率与更强质量追溯...在快速更迭、趋势驱动的鞋服产业链中,供需结构正从传统的大批量规模化制造向柔性化、小单快返与定制化服务形态加速演变。以往依赖人工扫码、纸质流转卡和经验管理的生产调度方式,已难以在更短交付周期、更高库存周转率与更强质量追溯要求的多重压力下维系稳定运转。对此,以射频识别(radio frequency identification,RFID)技术与生产执行系统(manufacturing execution system,MES)的深度协同为核心,构建一套贯穿仓储入库、工序采集、物料流转与成品出库的智能仓储与生产追溯体系,从编码体系设计、感知网络部署、工序事件建模、跨系统协同与追溯链路集成等方面展开论证,并验证该体系在识别精度、事件延迟、数据净化与系统同步等关键技术指标上的显著提升。展开更多
