Problems solved by technology

However, the indirect detection method cannot determine the cause of changes in pipeline pressure, flow, and temperature. Is it because the user is using the gas appliance normally, or the gas is not turned off, or is the pipeline leaking? In addition, the indirect detection method is only applicable to the detection of pipeline gas, not applicable to the situation where users use canned gas
[0010] To sum up, due to the unreliable gas detection method, the detection sensor's sensitivity is not high, or the work is not normal, accidents are frequent in homes or business places where gas leakage alarm systems are installed.

Embodiment Construction

[0032] like figure 1 As shown, the steps of the gas leakage monitoring method based on gas metering in this embodiment include:

[0033] 1) The target area to be detected is installed with a control terminal for judging whether gas leakage occurs, and the gas appliances in the target area to be detected are divided into two types: continuous gas consumption and non-continuous gas consumption. The first gas meter is installed on the main gas delivery pipe of the appliance, and the second gas meter is independently installed on the gas delivery pipe of each continuous gas appliance, so that the continuous gas appliance and the second gas meter are the same One-to-one correspondence, and connect the control terminal to the first gas meter and the second gas meter respectively, such as figure 2 shown; when the user needs to use gas, jump to the next step;

[0034] 2) The control terminal provides multiple gas usage options for the user to choose. The user selects at least one g...

Abstract

The invention discloses a gas leakage monitoring method and system based on gas metering. The method comprises the following steps: a control terminal, a first gas meter and second gas meters are installed at a detected target area, the control terminal provides a plurality of gas usage mode options to a user to choose, the user chooses at least one gas usage mode option through the control terminal, each gas usage mode option corresponds one modifiable default gas consumed volume or default minimum gas consumed volume, and whether gas leakage occurs is determined according to gas metering values of the first and second gas meters and the default gas consumed volume or the default minimum gas consumed volume. The system comprises the control terminal, the first gas meter and the second gas meters, and the control terminal is connected with the first gas meter and the second gas meters. User's normal usage and the gas leakage can be accurately discriminated, leakage monitoring accuracy is high, a fault is convenient to timely handle by a user, occurrence of a vicious accident brought by the gas leakage is prevented, and a comprehensive disposal with a traditional gas leakage method is convenient.

Description

technical field [0001] The invention relates to gas safety technology, in particular to a gas leakage monitoring method and system based on gas metering. Background technique [0002] At present, gas stoves, gas water heaters and other equipment have become necessities of life and have increasingly entered thousands of households. However, with the popularization of gas appliances, vicious accidents caused by gas leakage occur frequently every year. [0003] How to prevent gas leakage accidents and ensure the safety of gas appliance users is a hot topic for many researchers today. At present, related products sold internationally and domestically, as well as related scientific research achievements, mainly detect gas leakage and make various alarm systems to inform users of gas leakage, thereby avoiding the occurrence of vicious accidents. For example, the Chinese patent document with application number 201510549693.4 discloses a gas alarm system, which includes a single-ch...
