基于物联网的既有建筑全生命周期安全运维服务系统关键技术研究

RESEARCH ON KEY TECHNIQUES OF SAFETY OPERATION AND MAINTENANCE SERVICE FOR EXISTING BUILDINGS IN THE WHOLE LIFE CYCLE BASED ON INTERNET OF THINGS

针对不同年代、不同类型的建筑物进行不同种类的实时监测和定期"体检",有助于发现安全隐患,避免事故,达到提前预警,及时维护的目的,有助于提高建筑物的耐久性,有利于绿色发展和保护人民生命财产安全。提出了房屋全生命周期管理模式,探讨了基于物联网的建筑安全运维服务系统架构、运行模式、服务内容等,明确了基于物联网的建筑安全运维服务系统的各项子系统及其相应的功能,研发了微信服务号"建筑安全卫士"、基于物联网的大数据采集监测平台、建筑安全评估系统以及安全预警及辅助决策系统,简要介绍了贝叶斯网络、深度神经网络等多种先进算法在建筑安全评估中的应用以及基于物联网的自动化健康监测平台的关键技术,使得该系统能为各类用户提供各种实时服务和专业服务,完成建筑安全运维服务的目标,推动建立建筑物安全保障管理体系,助力智慧城镇建设,以有效的监测评估和安全运维管理形成城市发展的全周期闭环。

Different kinds of real-time monitoring and regular “physical examination” for buildings of different ages and types can help to find hidden safety hazards, avoid accidents, achieve the purpose of early warning and timely maintenance, improve the durability of buildings, facilitate green development, and protect the safety of people’s lives and property. This paper put forward the whole life cycle management mode of the house, discussed the frame, operation mode and service content of the building safety operation and maintenance service system based on the Internet of Things, defined the subsystems and corresponding functions of the building safety operation and maintenance service system based on the Internet of Things, and developed the WeChat service account “Building Safety Guard”, the big data acquisition and monitoring platform based on the Internet of Things, building safety assessment system/safety early warning and auxiliary decision-making system, this paper briefly introduced the application of Bayesian network, deep neural network and other advanced algorithms in building safety assessment, as well as the key techniques of automatic health monitoring platform based on Internet of Things, so that the system could provide all kinds of real-time services and professional services for all kinds of users to complete the goal of construction safety operation and maintenance services, to promote the establishment of building security management system, to help the construction of smart towns, and to form a full cycle closed loop of urban development based on effective monitoring and evaluation and safety maintenance management.
