1. System overview
Through the construction of the urban smart drainage pipe network monitoring system, the collection of data such as the state of the manhole cover on the pipe network, the liquid level of the pipe network, the flow rate of the pipe network, the harmful gas of the pipe network, and the water quality of the pipe network can be realized, and the operation status of the pipe network can be grasped in real time. Provide effective data support for the operation scheduling, maintenance management, and rapid response of the drainage pipe network, so that managers can grasp the actual situation in the pipe and correctly deploy emergency measures in emergency situations, and continuously improve the operation and management level of the drainage pipe network. The system is widely used in comprehensive monitoring and early warning projects such as smart cities, smart parks, smart ports, smart urban management, smart pipe networks, urban lifelines, smart security, and safe cities.
2. System architecture
1. Infrastructure layer
With the Internet of Things as the core of infrastructure construction, pipeline data, monitoring data, etc. are collected through various sensors and other equipment, and data is transmitted remotely.
2. Service support layer
It is mainly to establish various public services and information services on the infrastructure layer, including map services, statistical analysis services, etc.; and to provide interfaces and services for various business systems in the business application layer.
3. Business application layer
It is the entrance of the whole system for end users, the main entrance and interactive interface for all kinds of users to obtain the required services, and realizes various user interactive operations, information extraction, information processing, etc.
4. Specification and operation and maintenance guarantee
The system fully refers to various national technical specifications and industry standards, provides standardization basis in technology and management, and gradually forms information standards. At the same time, an operation and maintenance guarantee system must be established during construction to ensure the safe, stable and reliable operation of the system.
3. System functions
1. Collection of basic pipeline information
Realize the collection of information such as the location, height, and attributes of the pipe network pipeline; collect data on the operation of sewage plants and pump stations, collect regional water use conditions, and standardize management of pipe network information.
2. Pipe network perception data collection
Realize the monitoring data collection of manhole covers in the pipe network, realize the collection of pipe network liquid level, flow, water quality (conductivity, COD, ammonia nitrogen, total phosphorus, total nitrogen, PH) and other parameters, realize the collection and monitoring of operating parameters of pipe network pumping stations, and build a whole Intellisense for drainage networks.
3. GIS “one map” monitoring
Use GIS technology to build underground drainage network pipeline planning and analysis system, static sand table, etc., to achieve multi-dimensional visual display of drainage system; draw a three-dimensional underground drainage network dynamic “one map”, a global perspective of urban underground pipe network, comprehensive, Multi-angle and diversified dynamic display of geographic information spatial distribution.
4. Realize big data analysis
Through the drainage pipe network monitoring platform, the overall water quality, liquid level, flow and other monitoring and alarms can be realized, and the overflow alarm can be realized; the alarm and positioning can be carried out for pipeline silting, rain and sewage confluence, low-lying liquid level and waterlogging; the operation status and environment of the pumping station can be monitored. Participate in monitoring and realize unattended pumping stations.
4. System Features
1. Professional sensory equipment
Most of the equipment adopts explosion-proof, waterproof, dust-proof and other designs, and professional installation scheme design is carried out in combination with the actual situation of the pipe network. Most of the equipment adopts micro-power consumption design, which can be powered by both built-in battery and external power supply, with long service life, simple installation and maintenance. convenient.
2. Precise layout plan
Carry out targeted and professional layout scheme design from the “factory station network”, deploy and control corresponding equipment at key nodes such as branch pipes, main pipes, and main passages, comprehensively monitor the operation status of the entire drainage system, and realize full-link perspective.
3. Perfect monitoring platform
Based on a sound data system, a supporting platform for data sharing, dispatching and commanding, intelligent decision-making, information release, and intelligent collaboration has been built to ensure the effective operation of the intelligent pipe network monitoring platform, and truly realize the reporting of every change, the positioning of the report, and the positioning traceable.
4. Global full link monitoring
Utilize the Internet of Things, big data, cloud computing, and micro-service technologies to realize all-round monitoring from the source, access, and results of the drainage system, and realize refined management, business processes, intelligent inspections, assessment indicators, and intelligent decision-making.
