At present, central heating is widely used for heating in northern China during winter. The boiler room sends hot water to the heat exchange stations in various residential areas and enterprises through urban high-temperature heating pipelines. At the heat exchange station, the hot water in the high-temperature pipeline (hereinafter referred to as the primary network) exchanges heat with the hot water in the indoor radiator (hereinafter referred to as the secondary network) through a heat exchanger. After heat exchange, the hot water in the secondary network flows into each living room. Below, we will introduce the solution of Xinrongquan video surveillance software for heating systems:

In the above process, the heating dispatch department needs to centrally and real-time monitor parameters such as temperature, pressure, flow rate, and liquid level in heat exchange stations scattered in different geographical locations, and control the operation of various equipment in the heat exchange stations. At the same time, based on the operating parameters of each heat exchange station monitored on site, adjust the operating conditions of the thermal power plant to ensure the stable operation of the entire heating system in winter.

The current operation and management of thermal power stations in China is still in the manual operation stage, which affects the full play of the advantages of centralized heating. Mainly reflected in the lack of comprehensive parameter measurement methods, which makes it impossible to systematically analyze and judge the operating conditions; The system's operating conditions are difficult to eliminate, resulting in uneven heating and cooling for users; The heating parameters did not operate at the optimal conditions, resulting in a mismatch between the heating amount and the required heat; Incomplete operational data makes it difficult to achieve quantitative management.

To do a good job in urban centralized heating projects, it is necessary to comprehensively improve the level of heating technology. Therefore, establishing a foundation based onGPRSThe monitoring system of wireless network can achieve the collection of on-site parameters of each heat exchange station, real-time communication and control of data between the dispatch room and each heat exchange station, which can effectively solve the above shortcomings, improve the automation control level of the heating system, and greatly enhance the management level of the heating industry. Automatic control in heating engineering plays a crucial role in ensuring high-quality heating, safe operation, economic and energy-saving, and environmental protection of the heating system.

In the Xinrongquan video surveillance software system solution, the entire remote monitoring system for the heating network consists of three parts: the on-site heat exchange station control partGPRSData transmission section, dispatch room data center.
