At present, Industrial Internet of Things has become a new weapon for all walks of life to achieve transformation and upgrading. In practice, it can not only solve the efficiency and energy efficiency problems in the manufacturing industry, but also bring about intelligent changes to some infrastructure industries that affect the national economy and the people's livelihood.
For example, today in the domestic promotion of "Smart City", the wisdom upgrading of the water and heat supply industry has also become an inevitable trend. How to make use of Industrial Internet of Things technology to transform these industries?
It is not hard to see that many water and heating enterprises in many cities are in a period of seeking wisdom and change. There is a very strong driving force behind this demand. On the one hand, the trend of urbanization in our country makes the demand for public services such as water and heat supply in cities continuously expand, and residents' demands on the quality of these public services are also on the rise. Whether it is the traditional hardware and software infrastructure or the management and operation mode, Social and security needs have been facing enormous challenges.
On the other hand, the challenges come directly from the economic benefits of water and heat supply enterprises. Under the traditional model, a series of management factors and technical limitations make inefficient, lagged and wasteful phenomena visible in every aspect of energy, assets and manpower, seriously affecting the "hard indicators" of the profitability of enterprises. Only a smart transformation can make more water and heat supply enterprises get out of the bottleneck.
"It does not pass the pain," the extensive operation of water heating to form a chronic illness
So what practical pain points do they have at the operational and technical levels, respectively, for the industry practice of water and heat supply enterprises?
In the water industry, business operations cover all aspects from water sources, water pumping stations, waterworks, pipelines, end users, sewer networks, pumping stations to sewerage plants. In such a full life cycle, water companies face many challenges. For enterprises, the aging equipment, extensive management mode, making the enterprise in many cases can only rely on human experience to operate, the lack of very standard rules and norms. In addition, due to the limitations of automation and information technology, the overall return on investment of the entire enterprise is staying at a relatively low level. However, due to the lack of operation and continuity of operating experience, new employees find it difficult to quickly master the skills and solve the problems immediately when the experienced staff members leave or retire.
For the heating industry, there are similar challenges. For example, extensive and old management mode, production and management of multiple system switching, cumbersome operation, balance of water and heat imbalance, multi-heat source networking complex. Another problem is over-reliance on manpower. Because there is no uniform and effective strategy for the lag of heat network, load forecasting depends entirely on manpower. Heat exchange stations rely on manual maintenance and operation basically relies on labor, and basic data must be collected manually, Difficult to achieve efficient response, decision-making and optimization.
In fact, the most fundamental thing that runs through these enterprises is the common "chronic illness," which sums it up as "it does not matter but it hurts." In other words, due to the lack of transparency in data and systems, it is difficult to make real-time and accurate optimization decisions in all aspects of control, management and operation from the bottom to the top. Ultimately, these strategies can only rely on manual extensive management and adjustment. Wisdom I can not talk about it.
Innovation IoT architecture become the industry wisdom "weapon"
In this regard, the current architecture and tools based on IoT technologies are increasingly becoming a tool to improve the status quo. For example, Schneider Electric's new IoT-based EcoStruxureTM architecture can be a tool to help companies get the data and systems together and converge IT and OT.
EcoStruxurePlant has a three-tier framework of interoperable products, edge control, application / analytics and services to create an open, interoperable and interoperable ecosystem that essentially transforms data into intelligence and decision-making. The analysis of EcoStruxure's three-tier architecture, the underlying interoperability of the device includes all kinds of instruments, sensors, inverters and other intelligent components products; edge control layer includes DCS decentralized control, PLC process control, SIS safety control; the top is mainly Applications and analysis of software and tools, including energy management, production scheduling and supporting analysis, such as pipe network optimization, telemetry, operational control and management systems, as well as asset management and equipment operational status analysis, which Are some of the software and solutions that can be used by the company's analytical and decision-making staff.
Relying on this architecture, enterprises can connect their smart devices to technology and conduct real-time, extensive data collection to transfer critical data from sensors to the cloud. After that, the data is analyzed and transformed into valuable and meaningful analysis results, leading the final decision-making. Relying on this process, making equipment, personnel, management, operation of each change have been timely communication and feedback, the formation of closed-loop.
Open up the closed loop, to achieve smart water and heating applications landing
So, based on EcoStruxure this set of networking technology architecture solution platform, specifically how the water and heating industry applications?
EcoStruxure in the wisdom of water applications, first of all reflected in the water smart scheduling and optimization control. From the production of water to the supply of water, and then to the end of the client, it is all within the scope of dispatch management. A series of measures such as production, energy consumption, water leakage, water quality and hydraulic model prediction are needed. The entire water life cycle optimization scheduling.
In the meantime, this framework has essentially become the basic platform for the entire preventive operation and maintenance system. The production data can be transmitted to the asset management center through the CM (ConditionManager) component. The equipment model can be used to determine the status of the equipment and achieve forward-looking maintain.
Another typical problem in the water sector is water supply loss management. In this regard, combined with Schneider Electric GIS system and on-line hydraulic model, can effectively ensure the authenticity of the entire system. Relying on the business fees, customer service, remote data meter, SCADA real-time data and pipe network inspection system and other subsystems organic combination can help enterprises to better do leakage management, the formation of large data loss management system.
In the heating industry, EcoStruxure can also solve the challenge of smart heating through the organic integration of various layers of architecture. At the ground floor, equipment such as pressure sensors, transmitters, human-machine interface, HMI, PLC, frequency converter and so on can be provided for the heat exchanger station. In the control layer, data is collected and managed through the network of the VPN or through the cloud. Under the SCADA system through real-time with each heat exchange station to interact; up is the establishment of the application, analysis and service layer, constitute the data into the most important layer of value.
At this level, companies can rely on simulation and decision tools such as Termis and EMS for load forecasting, multi-heat source scheduling and energy optimization. Taking Termis production scheduling simulation system as an example, this system can realize the functions of temperature optimization, pressure optimization and multi-heat source production plan optimization through the establishment of a heat net model, which is an all-around hotline scheduling and management Expert system. At the same time, it is also an integrated system, it will SCADA
