Embodiment 1
[0052] Such as figure 1 Shown, a kind of resident indoor gas explosion risk assessment method, described method comprises:
[0053] First, according to the formula S=S 1 +S 2 +S 3 +S 4 Calculate the risk value S of indoor gas system defects, where S 1 is the preset risk value of Class A hidden dangers, S 2 is the preset risk value of Class B level 1 major hidden danger, S 3 is the preset risk value of Class B level 2 major hidden dangers, S 4 It is the preset risk value of Class B Level 3 hidden dangers.
[0054] The risk value of Class A hidden dangers can be obtained through Table 1. The staff will input the indicators in Table 1 into the computer system, and the computer system will directly calculate the final risk value of Class A hidden dangers. Class A hazards are very serious safety hazards, which may cause leakage of indoor gas facilities that endanger the lives and property of users and surrounding neighbors, as well as cause poisoning, fire, explosion and ot...
Embodiment 2
[0113] Corresponding to Embodiment 1 of the present invention, Embodiment 2 of the present invention provides a device for assessing the risk of gas explosion in residential buildings, the device comprising:
[0114] The risk value acquisition module is used to obtain the risk value S of the defect of the indoor gas system;
[0115] The impact value acquisition module is used to acquire the impact value E of personnel safety awareness;
[0116] The analysis value acquisition module is used to obtain the analysis value B of the vulnerability of the disaster-affected body;
[0117] The control force coefficient acquisition module is used to obtain the control force coefficient K;
[0118] The compensation factor acquisition module is used to acquire the emergency rescue compensation factor γ;
[0119] A hidden danger correction factor acquisition module is used to obtain the cumulative hidden danger correction factor τ;
[0120] The quarterly correction factor acquisition mod...

Abstract
The invention discloses a residential indoor gas explosion risk assessment method and a device. The method comprises the steps of obtaining a risk value S of an indoor gas system defect; obtaining a personnel safety consciousness influence value E; obtaining a vulnerability analysis value B of the disaster-affected body; obtaining a control force coefficient K; acquiring an emergency rescue compensation factor gamma; acquiring an accumulated hidden danger correction factor tau; obtaining a quarter correction factor mu; establishing a residential indoor gas explosion risk calculation model, andcalculating a residential indoor gas explosion risk value by using the residential indoor gas explosion risk calculation model; risk grading is carried out through a formula, Rmax is the maximum value of the gas explosion risk value in the resident house, and Rmin is the minimum value of the gas explosion risk value in the resident house; the method has the advantages that the method is simple and effective, and can be quickly applied to gas explosion risk assessment in residential households.
Description
technical field [0001] The invention relates to the field of indoor safety, and more specifically relates to a method and device for assessing the risk of gas explosions in residential buildings. Background technique [0002] With the acceleration of urbanization, natural gas has become one of the main energy sources for urban residents in my country. The rapid development of the natural gas industry is also facing severe challenges. Once a gas explosion occurs indoors, it may cause minor losses, or cause large-scale casualties and property losses, seriously threatening the lives and property safety of the people. According to statistics, from January 1 to January 31, 2019, a total of 51 gas safety accidents occurred across the country, resulting in 10 deaths and at least 43 injuries. Among them, there were 39 cases of indoor gas explosion and deflagration, and 12 cases of outdoor pipeline leakage and explosion. It is not difficult to see that residential gas users have b...
