Pipeline closing or blocking monitoring method and system for fire water supply system

Abstract

The invention discloses a pipeline closing or blocking monitoring method and system for a fire water supply system. The method comprises the steps that a standard pressure ratio is determined, a real-time pressure ratio is acquired, and the real-time pressure ratio is compared with the standard pressure ratio to judge whether a pipeline between detection points is blocked or a valve is located in a closed state, or judge whether a pipeline of a fire water tank leading to a fire pipe network is blocked or the pressure of a fire water tank is low. According to the method, the states of the fire pipe network itself and the fire water tank are determined by adopting the method of comparing the real-time pressure ratio between the detection points with the standard pressure ratio; the method is simple and accurate, whether the condition that the fire pipeline network is blocked or the valve is closed and the state that the water pressure of the fire water tank is reduced to a threshold value exist in the fire pipe network can be detected in real time, therefore, it is guaranteed that the whole fire pipe network ( including an automatic sprinkler system and a fire hydrant system) can be quickly used, and the loss caused by a fire disaster is reduced.

Description

technical field [0001] The invention relates to the monitoring field of a fire-fighting pipe network based on pressure detection, and particularly relates to a method and system for monitoring the closure or blockage of a fire-fighting water supply system pipe. Background technique [0002] With the rapid development of my country's economy, urban rail transit, high-rise buildings, hotels, guesthouses, office buildings and other buildings are increasing. Once a fire occurs in these buildings with complex functions, it will bring serious losses to the lives and property safety of the people, and it will also cause serious damage to the country. and social units bring great negative impact and economic burden. In actual production and life, the lack of fire-fighting water resources, unsound water supply facilities, and inadequate daily maintenance and management are the main reasons why small fires lead to large fires. [0003] In view of the above-mentioned problems, the auto...

Problems solved by technology

However, in actual fire safety supervision, in order to save the loss of fire water caused by leakage, the fire valve will be closed artificially. Once a fire occurs, it will not be able to respond quickly, causing great losses; The water is used for other purposes without being replenished, and the fire water supply is not timely when a fire breaks out, causing greater losses

[0004] In order to avoid the above problems, the prior art has a linkage system for automatic detection and automatic replenishment of the water level in the fire water tank, but this system does not have monitoring data, and linkage cannot be formed after a failure. Disabled to monitor
