[0041] Figure 1 It is a flow chart of a method for detecting the safety of combustibles provided in one embodiment of the present invention.

[0042] Figure 2 It is a structural schematic diagram of a device for detecting the safety of combustibles provided by one embodiment of the present invention. DETAILED DESCRIPTION

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] like Figure 1 FIG. 1 is a flow chart of a method for detecting the safety of combustibles provided by an embodiment of the present invention.

[0045] An embodiment of the present invention provides a method for detecting the safety of combustibles, comprising:

[0046] Step S1: obtaining the current concentration value and the current ambient temperature value corresponding to the combustible to be tested;

[0047] Step S2: Calculate and obtain the target combustion time corresponding to the current concentration value of the combustible to be tested at the current ambient temperature value;

[0048] Step S3: Determine whether the target combustion time value is less than a preset time threshold. If the target combustion time value is less than the preset time threshold, determine that the safety of the combustible to be tested is unqualified; if the target combustion time value is greater than or equal to the preset time threshold, calculate the target concentration expected value when the combustion reaction occurs under the current ambient temperature value. When the target concentration expected value is less than the preset concentration expected value, determine that the safety of the combustible to be tested is qualified. When the target concentration expected value is greater than or equal to the preset concentration expected value, determine that the safety of the combustible to be tested is unqualified.

[0049] For step S1, in a preferred embodiment, the current concentration value and the current ambient temperature value corresponding to the combustible to be tested are obtained. Specifically, in order to determine whether there is a fire hazard in the environment, it is necessary to determine the safety of the combustible, that is, it is necessary to obtain the current concentration value and the current ambient temperature value of the combustible to be tested to determine the safety of the combustible to be tested;

[0050] For step S2, in a preferred embodiment, the calculating and obtaining the target combustion time corresponding to the current concentration value of the combustible to be measured at the current ambient temperature value specifically includes:

[0051] The target burning time is calculated according to the following formula:

[0052]

[0053] Among them, SST is the target combustion time, c is the concentration value, m is the temperature value, P c It is the ignition point of the combustible material to be tested.

[0054] It should be noted that, according to the above formula, the combustion time corresponding to each concentration value of the combustible to be tested at the current ambient temperature or at other temperature values ​​can be calculated, so as to predict whether the combustible is safe in the current temperature environment according to the obtained time;

[0055] For step S3, in a preferred embodiment, it is determined whether the target combustion time value is less than a preset time threshold. If the target combustion time value is less than the preset time threshold, it is determined that the safety of the combustible to be tested is unqualified; specifically, because when the target combustion time value is less than the preset time threshold, it means that the current concentration value of the combustible may produce combustion within the preset time, it can be determined that the safety of the combustible to be tested is unqualified;

[0056] If the target combustion time value is greater than or equal to the preset time threshold, further evaluation is performed on each concentration value causing the combustion reaction at the current temperature to further determine whether the combustible to be tested is safe at the current temperature, and the target concentration expected value when the combustion reaction occurs at the current ambient temperature is calculated. When the target concentration expected value is less than the preset concentration expected value, it is determined that the safety of the combustible to be tested is qualified, indicating that the combustible to be tested does not pose a threat to environmental safety at the current temperature, and the safety of the combustible to be tested is determined to be qualified;

[0057] When the target concentration expected value is greater than or equal to the preset concentration expected value, it is determined that the safety of the combustible material to be tested is unqualified; specifically, when the target concentration expected value is greater than or equal to the preset concentration expected value, it means that the combustible material to be tested may pose a threat to environmental safety at the current temperature, that is, the safety of the combustible material to be tested is determined to be unqualified.

[0058] The present invention takes into account the current concentration of the combustible material and the current temperature of the combustible material when judging the safety of the combustible material to be tested, and calculates the combustion time and the expected value of the target concentration. The safety of the combustible material to be tested is then judged by judging whether the combustion time and the expected value of the target concentration exceed preset values, thereby improving the accuracy of judging the safety of the combustible material and effectively reducing the false alarm rate of the early warning.

[0059] In a preferred embodiment, calculating the target concentration expected value when a combustion reaction occurs at the current ambient temperature value specifically includes:

[0060] Obtaining a number of target concentration values ​​corresponding to when the combustible to be tested produces a combustion reaction at the current ambient temperature value, and calculating the target concentration expected value according to the number of target concentration values;

[0061] The target concentration expected value is calculated based on several target concentration values, specifically including:

[0062] Determine the weight corresponding to each target concentration value according to the judgment matrix method; wherein the judgment matrix method is a judgment matrix method based on the hierarchical analysis method, which uses a quantitative scaling method of pairwise comparison to determine the weights of the relative importance of different factors;

[0063] According to the weight corresponding to each target concentration value, the expected value of the target concentration is calculated by the following formula:

[0064]

[0065] Wherein, n is a target concentration value, and p is a weight corresponding to each target concentration value.

[0066] In a preferred embodiment, a safety assessment model for the combustion reaction between combustibles and oxidants is constructed, including: using a multi-factor analysis method to detect different combustible concentrations at different ambient temperatures to establish a safety assessment model for the time required for a combustible to burn.

[0067] Furthermore, the safety assessment model of the combustion reaction between combustibles and oxidants is constructed according to the following formula:

[0068]

[0069] Among them, n i Indicates the concentration of combustible matter, m i Indicates temperature, P c Indicates the ignition point of a combustible material. SST indicates the time required for the combustible material to be marked as burning in its natural state.

[0070] By constructing the above safety assessment model, the time required for a combustible to burn can be obtained based on the concentration of the combustible and the ambient temperature. If the time tends to be infinitely small, the environment of the combustible is 100% unsafe. If the time does not tend to be infinitely small, the ambient temperature can be used to further judge whether the environment of the combustible is safe.

[0074] The combustion time calculation module is used to calculate and obtain the target combustion time corresponding to the current concentration value of the combustible to be tested under the current ambient temperature value;

[0075] The safety determination module is used to determine whether the target combustion time value is less than a preset time threshold. If the target combustion time value is less than the preset time threshold, the safety of the combustible to be tested is determined to be unqualified; if the target combustion time value is greater than or equal to the preset time threshold, the target concentration expected value when the combustion reaction occurs under the current ambient temperature value is calculated. When the target concentration expected value is less than the preset concentration expected value, the safety of the combustible to be tested is determined to be qualified; when the target concentration expected value is greater than or equal to the preset concentration expected value, the safety of the combustible to be tested is determined to be unqualified.
