Intelligent pipe network control method and system

Abstract

The invention provides an intelligent pipe network control method. The intelligent pipe network control method comprises the following steps of acquiring an outdoor temperature T < outside > in real time, and determining a current theoretical water supply temperature T2 of a secondary network according to a mapping relation between the historical outdoor temperature T < outside > and the theoretical water supply temperature T2 of the secondary network; and collecting the current water supply temperature T1 and valve opening data of the secondary network, and adjusting the opening of a valve according to the T2 and the T1. The intelligent pipe network control method has the beneficial effects that 1, an initial workload of heating is reduced; 2, the workload of field technicians is reduced;3, front-end oversupply is reduced, and energy is saved; 4, oversupply in the heating season is reduced, and the energy is saved; 5, the problems of unbalanced temperature of the front and rear endsof a building and insufficient heat supply of the tail end are relieved; and 6, electric power is saved, and control is smooth and stable.

Description

technical field [0001] The invention belongs to the technical field of heating valve control, in particular 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 outlet water enters the plate heat exchanger of the heat exchange station, and the secondary network water circulates through the circulating pump and enters the heating area for heating. This heating method lacks various The balance adjustment method between heat exchange stations, the traditional adjustment method is a manual valve, based on experience, a fixed water supply for each heat exchange station is set for each network, and there is almost no adjustment for the entire heating season, resulting in uneven heat in each heat exchange station. The heat exchange station where the water supply from the primary network arrives first has oversupplied heat, and the user has already opened the win...

AI Technical Summary

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.
