Smart water construction is the trend of the times. On August 5th, 2013, the Ministry of Housing and Urban-Rural Development issued a notice to confirm that 103 cities (districts, counties, and towns), including Beijing's economic and technological development, will be the pilots of the 2013 National Smart City, and they will do a good job. The pilot work put forward specific requirements, and at the same time, it is clear that smart water is the nine major construction contents of smart city construction. Nowadays, smart new forms such as smart transportation, smart medical care, smart society, and smart water services are becoming part of us. It can be seen that with the development of information technology, smart water construction will be the trend of the times.
What is wisdom water? Smart water is an important component of a smart city. Its core concept is to use next-generation information technology such as the Internet of Things, cloud computing, big data, and mobile Internet to sense water status in real time through smart devices and collect water information. On this basis, Apply a unified public management platform to analyze and process massive information in a timely manner, so that the whole process of water source, water supply, water use, water saving, drainage, and flood prevention can be controlled in a more accurate and dynamic manner. Urban water managers provide support for decision-making, innovate water operations, management, and service models to promote the healthy and orderly development of smart cities.
Shijingshan District Water Supply Company combines many years of practical experience with the next-generation information technology such as “Internet of Things, cloud computing, big data, and mobile applications†to integrate the existing water supply automation system, MAPGIS management system, and water sales management system. The water supply dispatching platform and the DMA leakage control platform form a dispatch management and control model that integrates data collection, data analysis, comprehensive dispatch, and scientific decision-making to further improve water supply management and service levels. In this way, water supply automation and management collaboration are realized, providing a solid technical guarantee for achieving high quality, stable pressure, and safe water supply.
Independent to integration to improve management and service levels “In the past, our systems were distributed and independent. When problems occurred, we could only view the data of each platform separately and conduct analysis and resolution. Now we integrate these systems through data integration. Together, we have realized the unified management and analysis of production, revenue, pipeline network, and user data, and through big data analysis, the company's management personnel can grasp the operational status of the company in real time, and can find problems in real time through comprehensive analysis of key data indicators. , find and solve problems in a timely manner. For example, when we are doing water supply network maintenance, we can fully consider the surrounding pressure conditions and call data from a unified platform to determine the corresponding implementation plan." reporter.
The district water company also established a special DMA partition leakage management team to manage the network leakage control. According to the current status of water supply in the pipeline network, the group successively conducted DMA partition leakage control management in ten communities in Shijingshan District. According to Wang Hao, one of the pilots in the middle of the Bajiaozhongli Community experienced serious aging of the pipe network. The leakage rate was relatively high. It was difficult to locate leaks, which was time consuming and inefficient. Now through DMA management analysis helps us find the missing points in the pipe network. We first use the pipe network information provided by the GIS to determine the scope and boundary of the DMA community, and through a zero-pressure test, determine the integrity of its boundary valves. Then, according to the changes in the minimum flow at night, a divisional test plan was developed. Through the test, it was found that there was a significant leak in the pipe section. In Zhongli Zhongli Community, we quickly detected and located three pipe network leakage points, took timely measures to repair the pipe network, and replaced some of the old pipe network, so that the drop rate of the residential area was reduced by 24% before the renovation. To 6%, the loss level was significantly reduced. The next phase will also continue to monitor the water consumption in the community in real time, and timely identify leaks and timely maintenance on the basis of summarizing the laws of residential water use.
Through the successful implementation of pilot district DMA partition leakage control management, it is beneficial for water companies to sum up experience, effectively and rationally design DMA management plans, and effectively, continuously and stably control leakage. Through the effective replication and promotion of successful cases, Shijingshan District will gradually form a new model for monitoring, early warning and control of water pipe network leakage based on DMA. The economic and social benefits of water supply companies will also be greatly improved.
“Intelligent water construction is a long-term systematic project. Our long-term goal is to establish a comprehensive dispatching platform for intelligent management. In the future, we may be able to realize sitting in the office and we can find and solve problems in a timely manner through system data analysis. "Wang Xi said.

Beijing Promotes Smart Water Construction and Improves Management Level
[China Instrument Network Instrumentation Industry] A new round of scientific and technological revolutions and industrial changes are gestating around the world. Nowadays, at the national level, we are also very concerned about the continuous development and deep application of information technology, and the continuous transformation of the industrial management model. How to effectively integrate information technology with urban infrastructure and management systems is a new challenge for people. With the advent of the DT era, the use of big data to provide decision support for urban water services, and innovative water operations, management, and service models have become new topics in water management today. Today, the selection and use of digital, lean operations based on big data in water management have become the focus of various water supply companies. In 2015, Shijingshan District Water Affairs Bureau and the district water company launched smart water construction work. The district water company integrated the water supply automatic control system, the pipe network management system and the water supply marketing system, and also implemented the DMA partition management mode for the entire district's water supply network. Through the establishment of a management information platform, a multi-institution multi-level water supply information sharing was formed, data communication between Yangzhuang Water Plant and Wulijing Water Plant was realized, and a safe and reliable water supply management system and information security system were established.
