Problems solved by technology

As a result, this work needs to be repeated, and in the middle of the heating period, due to the cooler weather, the balance will be broken again, and the overall leveling work needs to be done again, with a huge workload
This leads to a contradiction, if no leveling is done, it will lead to waste of heat supply or insufficient heat supply leading to complaints
When doing leveling, the labor cost is rising, and the balance is still not guaranteed. The waste situation is only to alleviate a part of the design of the chief technical engineer, which cannot be fully realized. The general labor union of each heating company designs a complete set of heating standards according to its local conditions.
However, due to the lack of effective control means, there are often reasons such as the technical level of the workers and the adjustment time caused by the geographical location, which cannot be realized.

Embodiment

[0026] like figure 1 As shown, a flow chart of the intelligent pipe network control method of the present invention is shown, and the intelligent pipe network control method includes the following steps:

[0027] Real-time collection of outdoor temperature T 外 , according to the historical outdoor temperature T 外 The mapping relationship with the theoretical water supply temperature T2 of the secondary network determines the current theoretical water supply temperature T2 of the secondary network;

[0028] Collect the current water supply temperature T1 and valve opening data of the secondary network, and adjust the valve opening according to the size of T2 and T1; T2 is the range value or point value; among them, the mapping relationship can be a temperature curve, such as Figure 14 As shown, two temperature curves are shown, and one or two of them can be selected according to the specific situation, or different temperature curves can be collected at different time period...

Abstract

The invention provides an intelligent pipe network control method, the intelligent pipe network control method includes the following steps: collecting the outdoor temperature T in real time 外 , according to the historical outdoor temperature T 外 The mapping relationship between the theoretical water supply temperature T2 of the secondary network determines the current theoretical water supply temperature T2 of the secondary network; The beneficial effects of the present invention are as follows: 1. Reduce the initial workload of heating; 2. Reduce the workload of on-site technicians; 3. Reduce the front-end oversupply and save energy; 4. Reduce the oversupply in the heating season and save energy ; 5. Alleviate the problem of unbalanced temperature at the front and back ends of the building and insufficient heating at the end; 6. Save electricity, control smooth and stable.

Description

technical field [0001] The invention belongs to the technical field of heating valve control, and particularly relates to an intelligent pipe network control method and system. Background technique [0002] The existing heating method usually heats the secondary network water after the boiler effluent enters the plate heat exchanger of the heat exchange station, and the secondary network water is circulated through the circulating pump and enters the heating area for heating. The balance adjustment method between heat exchange stations, the traditional adjustment method is manual valve, set a fixed water supply for each heat exchange station primary network based on experience, and then almost no adjustment is made throughout the heating season, resulting in uneven heat in each heat exchange station. The heat exchange station that the primary network water supply arrives first is oversupplied, and the user has opened the window to dissipate heat due to the high room temperat...
