With the in-depth integration of Tianjin’s cutting-edge artificial intelligence technology with all walks of life, the high-tech that sinks into our daily lives has unknowingly changed our lives. Every winter, every household cannot do without heating, and there are also many smart “black technologies” hidden here. Recently, the reporter came to the heating dispatching command center of Tianjin Energy Group to learn about the construction and operation of Tianjin’s smart heating system.
Here is the first domestic networked peak shaving “one network” heating system integrating heat and power, clean and high-efficiency pulverized coal boilers, gas boilers, geothermal, air sources and other heat sources, realizing 100% clean heating and multiple heat sources Complementary protection. In this large network that maintains the “temperature” of the city, smart technology has been applied to all aspects of the system.
“In the traditional heating system, the boiler in the heating station can only supply the water to the limited area around it. Under the’one network’ system, the heating stations are effectively connected in series, and a station appears. The failure will be immediately repaired by other sites. If the traditional heating system is a single cycle of human blood, then’one network’ can realize the mutual blood transfusion between people.” During the interview, Tianjin Energy Group Heating Dispatching Liu Huanzhi, deputy director of the customer service center, told reporters that with the rapid development of smart technologies such as big data and the Internet, technologies in the heating field are also changing with each passing day. An intelligent heating network not only connects the warmth of thousands of households, but also allows the entire industry to enter the fast lane in the process of transformation and upgrading.
Liu Huanzhi introduced that the intelligent brains of “One Net” are connected at multiple levels. There are 7 sub-centers under the first-level dispatching command center, with more than 2500 heat exchange stations connected in series, covering a heating area of 150 million square meters to serve the city. 1.1 million users have played a role in dealing with rare extreme cold and cooling weather, solving a series of difficult problems such as the failure of power plant units, the increase of heating room temperature standards, and the limited heating output of major power plants on the grid, the shutdown of units, and the shortage of upstream gas sources. Played a vital role.
In the heating season, the heat exchange station is not only the main body of the user’s heat supply, but also the center of regional regulation. It plays a key role in the process of intelligence and can be called the “heart” of heating. Since 1996, the construction of unattended remote monitoring and automatic control of heat exchange stations has been started. Through continuous optimization of the control platform, Tianjin Energy Group has realized remote monitoring and fully automatic and refined operation of all heat exchange stations, which has greatly improved the heat exchange. The operation control level of the station and the ability to coordinate with the heating network have realized energy saving and consumption reduction. At the same time, the use of the Internet of Things and infrared thermal imaging, video surveillance, flooding, noise and other full-element monitoring and automatic response technologies in the heat exchange station have effectively improved the level of safe operation in the station.
With a strong heart, there must be healthy blood vessels. In the inspection of the heating pipe network, the “drone + dual-light thermal imaging” intelligent inspection system developed by the group made the “running drip” hidden under the ground invisible, filling the domestic industry blank. Liu Huanzhi introduced that when the heating pipeline is buried underground, it is difficult to find and locate it in time through manual inspection. This is likely to cause heat outages in the pipe network and affect the heating of residents in winter. Through the drone equipped with infrared thermal imaging equipment, hot water leakage can be found at any time from high-altitude inspections. Compared with the traditional heating pipeline leakage detection method, it not only greatly reduces the workload of breaking the road and shortening the search time It saves the cost of repairing broken roads, and can also provide data basis for formulating scientific emergency repair plans, which greatly improves the efficiency of emergency repairs of the heating pipe network.
In addition to hardware intelligence, on the user side, intelligent technology also provides assistance for the improvement of the “soft power” of heating service levels. The precision heating project based on AI technology collects data in real time and performs big data analysis and dynamic and precise adjustment to ensure that the user’s room temperature is more comfortable and avoid overheating or overcooling; the customer service system adopts manual + AI intelligent voice, and residents apply for repairs online with one click It can effectively reduce the waiting time for repairs; Tianjin’s first 24-hour visual self-service heating service hall has been opened, and people can handle heating services by themselves around the clock; comprehensive online and offline integrated convenience service platforms have been built to achieve all 23 heating services. Going home online, “no need to run once”… These smart application scenarios make things more convenient for the people, and the services they harvest are more efficient and accurate.

“In the future, we will continue to improve the intelligent and precise service level of the system, make the heating system safer, more stable and efficient, and make the people warmer and more comfortable in the winter.” In May this year, the Fifth World Intelligence Conference will be held in Tianjin. Liu Huanzhi revealed that this year the group will bring one-key automatic start-stop smart heat exchanger units, smart manhole covers and other product projects to the conference. At that time, visitors will have the opportunity to experience how the smart heating system works through VR technology on site, and get to know Tianjin Smart “gold content” in the field of heating.
