Description

technical field [0001] The invention belongs to the field of heating, ventilation and air conditioning, and in particular relates to a method for realizing transparent heating and a system for realizing the method. Background technique [0002] With the rapid development of the city, the central heating system, as the basic security facility of the city, is getting larger and larger, the system is becoming more and more complex, and the impact of failure on the society is increasing, so the reliability requirements are also increasing. higher. However, the failure of the system is inevitable, but when and what kind of failure occurs is accidental. In view of the contingency in this inevitable situation, it is difficult to find it in time by relying on the traditional manual inspection method, and the lag is too large to meet the current requirements.

However, the failure of the system is inevitable, but when and what kind of failure occurs is accidental. In view of the contingency in this inevitable situation, it is difficult to find it in time by relying on the traditional manual inspection method, and the lag is too large to meet the current requirements. The reliability requirements of infrastructure, only by developing a system that can realize automatic fault diagnosis, can it be possible to respond quickly and timely, and can it be possible to meet the development needs of smart cities. Yes: By installing a small number of sensors, try to speculate on the current state of the system through potential physical laws (such as energy conservation, mass conservation, momentum conservation, etc.) and various assumptions, and make system fault judgments based on the speculated state and operational management,

Obviously, with a small amount of sensor data, it is very difficult and unrealistic to rely on an advanced strategy or algorithm to achieve timely, accurate, reliable fault self-diagnosis and efficient operation.

In the current system mode, even if the heating system is installed with an automatic control system, it is still mainly "monitoring", it is difficult to "manage" and "control", and it is even more difficult to control it well. Evenly” and some of the time the overall “overheating” is still serious, the energy consumption is still high, and there are even many cases where operators abandon the installed automatic control system
