Hefei City lifeline project

Safe urban development is an important prerequisite for people to live a better life, and urban infrastructure such as Bridges, gas, water supply, drainage and elevators in a city is the lifeline of a city, which is responsible for the functions of information transmission, energy transmission, flood drainage and disaster reduction。Hefei attaches great importance to the safety of the city's lifeline，2016年起，Hefei takes the lead in developing and implementing the safe operation monitoring system of urban lifeline engineering in China，We will build a comprehensive support platform for the safe operation of urban lifeline public infrastructure，Jointly weave a comprehensive, three-dimensional urban operation safety net，Build a new business model of "smart and safe city"。

Hefei City lifeline engineering safety operation monitoring system project includes bridge safety, gas pipe network, water supply pipe network, drainage pipe network and heat pipe network，In accordance with the overall construction principles of overall planning, top-level design, resource sharing and intensive construction，The combination of "point, line and surface" is applied to expand the results，Build a comprehensive support platform for safe operation of public infrastructure of Hefei Urban Lifeline Project，Innovate the urban management model，3 "unities"（Unified standards, unified supervision and unified services），4 "comprehensive"（Comprehensive awareness, comprehensive access, comprehensive monitoring, comprehensive early warning），5 "landing"（Risk visualization, standardized supervision, transparent operation, refined management, and proactive protection) construction goals。

Drainage network safety monitoring system contracted by Changtai Technology，By installing a series of monitoring equipment and sensors (flow/level/silt thickness/water level/water quality/combustible/toxic gas monitors, pumping station operation monitoring equipment) at key locations of the drainage network in urban areas.，Through 4G/5G/NB-IOT/GPRS and other transmission methods to converge to the data processing platform，Aggregated, processed, analyzed and shared by the data platform，Provide comprehensive real-time monitoring data for business systems，And provide powerful data support for real-time decision-making。Compared with before operation, the accident rate of the city's underground drainage pipe network has been greatly reduced, and the risk investigation efficiency has been significantly improved, which has effectively improved the urban safety risk prevention and control capacity of Hefei City。

The system integrates public safety technology with modern information technologies such as the Internet of Things, cloud computing, and data to realize timely detection of security risks and rapid response to emergencies。It has realized the timely discovery of risks and hidden dangers of underground pipe networks in the old urban areas, high-risk areas, and underground pipe networks with livelihood protection projects and sensitive areas, greatly improved the safe operation management level and service level of urban lifeline projects, improved the active security guarantee ability of Hefei City, and effectively improved the happy life index of urban residents。
