Abstract: With the process of industrialization and the rise of industrial parks, the demand for central heating is increasing year by year. At present, most of the enterprises in the park are not centralized, and the steam is mostly transported by long-distance pipelines However, due to geographical, traffic, construction and other factors, the design and installation of steam pipe network in the park has buried, overhead, river and other sections, pipeline laying path complex, unfavourable operation of hillside slope and Canal section, routine inspection and maintenance work of maintenance personnel. With the help of digitalization, the real-time temperature monitoring system can effectively improve the economy and reliability of heat network operation.
