Cold region water supply and drainage pipe anti-freezing monitoring method and system

Abstract

The invention relates to a cold region water supply and drainage pipe anti-freezing monitoring method and system, and belongs to the technical field of water supply and drainage pipe anti-freezing. The method comprises the steps of collecting environment temperature information of a current to-be-detected water supply and drainage pipe, and processing the environment temperature information to obtain a freezing flow speed value; collecting a water flow rate value of the water supply and drainage pipe exposed on the ground, comparing the water flow rate value with the freezing flow rate value,and emptying or accelerating water in the water supply and drainage pipe exposed on the ground if the water flow rate value is smaller than or equal to the freezing flow rate value; collecting the temperature of the environment where the water supply and drainage pipe is located in real time, and enabling the freezing flow rate value to be easier to obtain according to a corresponding relation between the environment temperature information and the freezing flow rate value; and comparing the collected water flow rate value with the obtained freezing flow rate value, treating the water in the water supply and drainage pipe automatically and accurately and ensuring that the water supply and drainage pipe is not frozen, so that waste of water resources is reduced.

Description

technical field [0001] The present application relates to the technical field of antifreeze for water supply and drainage pipes, in particular to a monitoring method and system for antifreeze of water supply and drainage pipes in cold regions. Background technique [0002] In modern buildings, especially high-rise buildings, the design and installation of water supply and drainage pipes is an essential work. In winter in cold regions, the temperature can reach below minus ten degrees Celsius. If there is residual water in the water supply and drainage pipes at this time, it will freeze and freeze, which will damage the water supply and drainage pipes and affect the normal water intake of houses in the building. [0003] At present, when it is expected that the temperature may reach freezing temperature in cold winter, the staff often discharge the residual water in the water supply and drainage pipes into the main well by opening the water discharge valve after the water pum...

AI Technical Summary

Problems solved by technology

However, in order to prevent the water supply and drainage pipes from being damaged by freezing, the staff may drain the residual water from the water supply and drainage pipes exposed on the ground when antifreeze is not needed, resulting in a waste of water resources.
