1城市地下综合管廊实施的布局
1. Layout of urban underground utility tunnel
按照收容管线的不一样,地下综合管廊分为干线、缆线、3151/3051在线式密度计_城市地下综合管廊管理集成优点
支线这三种综合管廊。
According to the different receiving pipelines, the underground utility tunnel is divided into three types: trunk line, cable and branch line.
2地下综合管廊智能化管理系统
Intelligent management system for underground utility tunnel
地下综合管廊既要实现系统的安全、稳定运行,又要实现对供电、消防、照明、通风、排水等系统的集中管理
The underground utility tunnel should not only realize the safe and stable operation of the system, but also realize the centralized management of power supply, fire protection, lighting, ventilation, drainage and other systems
(1)感知层:通过传感器、摄像头采集整个管廊气体;通过温湿度、水位、电力、通信数据实现对整个管廊运行状态的感知;通过风机、水泵、配电、照明、消防实现整个管廊的安全运行。(2)接入层:提供统一的设备接入服务,提供多种通信终端产品及接入方案,采用统一的数据采集及控制接口模型,支持各种工业通信协议,可轻松实现在各类环境中传感器、通风设备、配电设备、燃气设备以及排水设备的快速接入。
(1) Perception layer: collect the gas of the whole pipe gallery through sensors and cameras; realize the perception of the operation state of the whole pipe gallery through the temperature and humidity, water level, power and communication data; realize the safe operation of the whole pipe gallery through fans, pumps, power distribution, lighting and fire protection. (2) Access layer: it provides unified equipment access services, provides a variety of communication terminal products and access schemes, adopts a unified data acquisition and control interface model, supports various industrial communication protocols, and can easily realize the rapid access of sensors, ventilation equipment, power distribution equipment, gas equipment and drainage equipment in various environments.
(3)传输层:采用有线及无线通信网络,分布式消息中间,实现安全可靠的双向数据交互,确保各类感知数据的实时采集以及远程控制命令实时到达和执行,无缝连接大数据服务中心。
(3) Transmission layer: adopt wired and wireless communication network and distributed message center to realize safe and reliable two-way data interaction, ensure the real-time collection of all kinds of sensing data and the real-time arrival and execution of remote control commands, and seamless connection with big data service center.
(4)数据层:由消息中间件、数据缓存服务、数据分析服务、实时数据流服务、NoSQL数据库平台,依托先进的数据库集群技术、云计算技术以及大数据处理技术,构建智慧管廊大数据处理系统。提供从终端到头端,从设备到业务,从数据到运营决策的全业务、全数据、全覆盖的整体解决方案。从而打造以统一管理为基础,以业务数据为中心,以提高用户满意度和粘度为落脚点的全新解决方案。
(4) Data layer: the smart pipe gallery big data processing system is constructed by message middleware, data cache service, data analysis service, real-time data flow service and NoSQL database platform, relying on advanced database cluster technology, cloud computing technology and big data processing technology. It provides an overall solution of full service, full data and full coverage from terminal to head end, from equipment to business, and from data to operation decision. In order to create a unified management as the basis, business data as the center, to improve customer satisfaction and viscosity as the foothold of the new solution.
