Embodiment Construction

[0041] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0042] refer to figure 1 , the present embodiment discloses a gas leakage alarm method, which includes the following steps:

[0043] S1. Obtain the sum of the rated heat loads of the gas equipment owned by the user.

[0044] The types and quantities of gas appliances in different users' homes may be different, and these gas appliances include gas water heaters, gas stoves, gas dryers, gas boilers, and the like. Taking the gas stove as an example, the gas stove may have two burners or four burners. The number of burners is different, and the rated heat load is also different. Taking a water heater as an example again, its rated heat load may vary depending on its water supply flow and energy efficiency. Therefore, in order to realize the alarm more accurately, this embodiment obtains the sum of the rated heat loads of the gas equipment owned ...

Abstract

The invention discloses a gas leakage alarm method and system. The method comprises the following steps: acquiring the sum of rated thermal loads of all gas equipment of a user; setting a large flow threshold value according to the sum of rated thermal loads of all gas equipment of the user; acquiring the minimum operating thermal load of the gas equipment of the user; setting a small flow threshold value according to the minimum operating thermal load; acquiring the flow of a meter of the user; and triggering an alarm and / or cutting off the air supply of the user according to the flow of themeter of the user, the small flow threshold value and the large flow threshold value. According to the gas leakage alarm method and system, the large flow threshold value is set according to the sum of the rated thermal loads of the gas equipment actually used by the user, and the small flow threshold value is set according to the minimum operating thermal load of the gas equipment, so that the method and the system better conform to the use rule of each user, the alarm is more accurate and effective, and the situation of false alarm is reduced. The gas leakage alarm method and system can be widely applied to the technical field of gas safety.

Description

technical field [0001] The invention relates to the technical field of gas safety, in particular to a gas leakage alarm method and system. Background technique [0002] At present, with the popularization of gas engineering, piped gas has entered thousands of households. At present, most buildings in major cities have laid gas pipelines. While piped gas brings convenience to your life, it also has potential safety hazards. Therefore, it is particularly important to beware of gas safety accidents. [0003] The current gas metering monitoring system usually only sets the flow threshold based on empirical values, and generates an alarm when the relationship between the actual flow and the flow threshold meets the set conditions. However, the gas flow rate is different for each household, so misjudgments often occur in the prior art, and it is impossible to accurately and effectively determine whether the user's gas is abnormal. Contents of the invention [0004] In order t...
