Wise Water Wraps Up the Top Ten 2016 Hot Words Can You Really Know?

[China Instrument Network Science and Technology] If you let Xiaobian summarize the top ten hot words in the water industry at the end of the year, the term “Wisdom Water Service” is definitely on the list. It is vague to remember that after the concept of IBM's "Smart Earth" was put forward, wisdom water service emerged as the times require. In a few years, the watch factory was renamed, and various types of wisdom water forums blossomed. Even the micro-letter group of Xiaobian had more and more groups under the name of smart water, and the GIS and SCAD departments were no longer strangers. The upsurge in the water industry. What is the smart water service in the end, and what is its implementation path?

At present, the application of “intelligent solutions” based on information technology in China’s Water Division mainly includes the following: SCADA system, including data on water volume, water pressure, water quality, and water level. The business charge system includes data such as user, water type, and water fee payment. The GIS system (geographical information system) includes asset space data such as pipelines, valves, and flow meters. Maintenance and maintenance system, including pipeline inspection, on-site maintenance, leak repair, pipeline replacement, work order distribution and other information. Customer service hotline system, including customer complaints, repairs, leaking water reports and other data.

Although the application of informatization technology in China's water division has become increasingly widespread, there are still some problems:

First, the planning is not in place. There is a lack of strategic, holistic and forward-looking IT planning. The phenomenon of “headaches and treatment” is more prominent.

Second, heavy hardware and software, severe information island problems. In practice, the water department hardware equipment is much more installed, the software application is less, and for the software project, the custom development is much more flexible, and the scalability is poor, resulting in two adverse consequences: First, the data between the systems Without exchange, an island of information is formed one by one. The final part of the project is turned into an informatization burden. Second, the information and data are complex and difficult to make effective use of management and decision-making.

Third, there are barriers to service communication. On the one hand, passive services lack the sense of dignity and respect brought by high-level services. On the other hand, customer service and communication channels are relatively simple.

Smart Water Construction and Its Implementation Path

Principles for the construction of smart water services In order to solve many problems in the application of information technology in water divisions at present, the following principles should be followed in the construction of smart water services:

Standardization, based on mainstream technologies and standards, establish and improve various technical specifications and systems.

· Process, based on workflow to achieve business processes.

· Integration, data integration and information integration between multiple systems.

· Simplification, simple user operation and experience.

Advanced nature, long-term planning for the development of technology and applications, both compatible with the current conventional architecture and support for future big data and cloud computing environments.

System Architecture of Smart Water Services The system architecture of smart water services follows the traditional four-level principle of the Internet of Things. Specifically, the most basic "perceptual layer" includes monitoring or data collection equipment for information such as water quantity, water pressure, water level, water quality, and leakage. These data are entered into the "storage layer" of data through the "transport layer" formed by mobile communication, Internet, Bluetooth, etc., and through the mining of these data, the "application layer" is represented by various functional modules or platforms. Comes out, assists the management decision-making behavior and helps the operating layer execute behavior.

Implementation path For most of the current domestic water divisions, the starting point for smart water construction is not a blank sheet. Instead, it needs to be based on the strategy and development objectives of the Water Division, integrate the status quo and conduct overall planning, and formulate plans for distribution and implementation. In the implementation process, in order to solve the problem of “information isolated islands” and make the data generated by each business system be used effectively, it is necessary to integrate and upgrade the existing business systems and build an integrated management platform that can integrate data of various business systems. Based on the need to provide managers with intelligent decision support, develop different functional modules. One of the key points is the integration of data from different business systems. In theory, data from different systems is massive, and mining and analysis of them can produce different functional modules. In order to make smart water construction easier to land, it is necessary to find a breakthrough that meets the development requirements of the Water Department, and then gradually expand the functional modules of the integrated management platform under the premise of continuous improvement of data and continuous improvement of management level.

Production and sales difference management

Poor management of production and sales is the most easily breached ground. The reasons are as follows:

• The difference between production and sales is a problem that all water companies have started or will pay close attention to in the future. Its significance to the Water Department is reflected in: in the case of scarce water resources, it can make more efficient use of resources; at the relatively low levels of water prices controlled by the government, it reduces chemical pollution and energy consumption; and it slows the infrastructure construction of water supply systems. Reduce investment; an important indicator of the technical and management level of water supply companies.

• The production and sales difference is a comprehensive issue involving the integration of existing business system data and the responsibilities of various departments in the management of production and sales difference.

· Poor management of production and sales can make it easier to find business models. Take Shanghai City Water Investment Group as an example, the average water supply scale is 6 million tons/day, the current residents' water price is 1.92 yuan/ton, and the economic benefit saved by reducing 1% of production and sales difference is about 42 million yuan; If the level of % is reduced to 15%, the accumulated savings will be 550 million yuan.

Scientifically construct water supply dispatching decision system

Taking the application of hydraulic model as the core, the first step is to realize the integration of source water supply and dispatch, and to create a network dispatch system from the source to the tap. At present, there are three problems in China's Water Division's water supply dispatch system:

• Limited monitoring tools and data cannot fully reflect the hydraulic status of the pipeline network.

· Based on the artificial experience of the scheduling, its comprehensiveness, consistency, stability, and passability are relatively poor.

• The traditional methods of issuing instructions are poorly traceable, making it difficult to perform effective statistics and analysis, and thus optimize scheduling.

The water supply dispatching system takes the hydraulic and water quality model as the core and integrates data from GIS systems, SCADA systems, new and existing dimensional systems, pump station energy efficiency assessment systems, crisis and plan management systems, and large valve management systems, and outputs online monitoring and alarms. Model prediction, crisis and plan management, charts and reports, and other auxiliary decision analysis, online scheduling and instruction management, emergency response event management and other information, to achieve real-time monitoring, auxiliary decision-making and scientific scheduling instructions issued functions. This kind of scientific dispatch system based on the application of hydraulic model can implement reasonable dispatching measures according to water demand, optimize the operation of the pipeline network, and reduce the operation and maintenance costs of the pipeline network on the basis of ensuring the safety of water supply.

Build an energy management system

Starting from the major sources of energy consumption in the Water Division, starting with energy-saving renovation and monitoring of electricity consumption in pumping stations, building an energy monitoring and management platform, and carrying out integrated measures such as energy consumption monitoring, data integration analysis, optimized scheduling, pump efficiency testing, transformation and transformation of power distribution systems, etc. The establishment of an integrated energy management platform can provide information and aid decision-making for the energy conservation and consumption reduction of the Water Division, helping the Water Division to reduce costs and increase efficiency. Establish integrated energy management platform in the whole process of water service business, including electricity, water, gas, heat, etc., as well as pumps (including various types of pumps, all types of fans, motors, etc.), power distribution equipment (transformers, etc.), and lighting (Including offices, buildings, factory workshops, etc.), heating (boilers, steam, etc.) and other energy-consuming applications of integrated management to optimize the management of energy use.

Specifically, by using energy-consuming data collection and energy monitoring of energy-using equipment, energy consumption can be effectively managed and controlled, energy-saving transformation of necessary equipment and systems can be carried out, and an energy-saving information management platform can be built to achieve cost reduction and efficiency increase. In the raw water and water supply sectors, the power consumption of water plants and transmission and distribution network pump stations accounts for as high as 90%. Among them, water pump units and power transformers are the most important sources of energy consumption. Energy efficiency analysis and transformation of pump stations can be carried out as well. The implementation of energy monitoring methods to implement energy-saving emission reduction and efficiency. In the sewage and drainage sectors, water pumps, blowers, sludge dewatering units, and power distribution transformers are the main sources of energy consumption. They can transform backward technologies and power distribution equipment, conduct power monitoring of energy-consuming equipment, and pump stations for power plants. The implementation of energy-saving, emission reduction, and efficiency enhancement is implemented in such ways as the transformation of green lighting.

Conclusion

The construction of smart water service has very good social and economic benefits. It can not only make more rational use of water resources, ensure water quantity, water quality, water pressure and water supply safety, but also provide users with a higher level of water supply services and reduce leakage due to pipe network leakage. Or the impact of explosion pipes on pavement construction, urban transportation and users' production and living can also improve the operation and maintenance level of the water company and maintain a reasonable operation and maintenance cost, thereby alleviating the pressure of rising water supply costs on water prices. In the construction of smart water services, the water divisions should closely integrate the advanced Internet of Things technology and water management according to the actual situation and in accordance with the principle of overall planning and implementation of divisions, start from the most easily settled projects, and gradually improve wisdom. Water construction.
