背景技术
智慧楼宇(Intelligent Building)也称智能建筑、智能楼宇,是将建筑、通信、计算机和控制等各方面的先进科技相互融合,合理集成为最优化的整体,形成能够适应信息化社会发展需求的现代化新型建筑。
智慧楼宇主要满足楼内三个层次客户的需求:业主、楼内租户、楼内个人。业主的需要通过数字化技术改造楼宇基础设施,实现更智能的自动控制、安全监控、节能减排、人员管理等,降本增效。楼内租户希望楼宇能提供更多数字化服务,更便捷、更低成本地获得通信和信息技术,快速构建数字化转型所需要的能力。楼内个人需要能解决移动网络覆盖,通信随时随地高速畅通。
在目前的楼宇智能化建设实践中,形成了三张网,即基础通信网、自动控制网和企业信息网。通信网由电信运营商建设和运营,包括4G/5G的楼内覆盖、光纤到楼/到户,为楼内客户提供基础通信、宽带接入服务。自控网由楼宇业主委托建设和运营,实现对楼内水路、电路、空调、电梯、安防、停车场、物业等关键基础设施的自控控制功能,保障楼宇公共服务。企业信息网由楼内商企租户建设和维护,实现商企自身需要的办公信息化、管理数字化等需求。
目前楼宇中的三张网是相互独立的物理网络,由不同的主体负责建设,各自为战,存在下列缺点:三张网之间无法形成协同效应,例如,自动控制网和企业信息网的业务需求,不能用于知道基础通信网动态调整优化,降低了三张网的效能。三张网有部分设施重复建设,很大程度 上增加了企业成本负担。三张网内需要部署计算资源,或者使用物理服务器,这样运行维护复杂度会很高;或者租用公有云主机,这样会需要公网访问,要满足性能和安全性的要求需要较高成本。此外,目前楼宇中的三张网不利于节能环保。
