[0058] Figure 2 It is a flowchart of the steps of the Analytic Hierarchy Process (AHP). DETAILED DESCRIPTION

[0059] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in combination with the embodiments of the present invention. Obviously, the described embodiments are 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.

[0060] Embodiment 1:

[0061] Construct a combustible gas monitor inspection experimental platform system, collect data measured by the combustible gas monitor under complex conditions, propose key performance indicators of the combustible gas monitor under complex conditions, use the hierarchical analysis method to analyze and determine the weights of the evaluation index system, and use the value function method to judge the characteristics of the combustible gas monitor.

[0062] (1) Build an experimental platform system

[0063] The combustible gas monitor experimental platform system includes a standard gas concentration calibration module, a temperature and humidity environment control module, and a data transmission and analysis module.

[0064] Standard gas concentration calibration module: consists of a standard methane gas cylinder and a gas storage device, used to provide methane gas of standard concentration.

[0065] Environmental control module: It is composed of a climate chamber and a cabinet controller, and is used to generate different temperature and humidity environments. It is the control unit of the environment in which the gas monitoring equipment is located. The environmental chamber can realize the following environments: high and low temperature environments, with a temperature range of -40℃ to 80℃, using glacier refrigerant as the refrigerant for low temperatures, and electric radiation heating plates for high temperatures; rainy environments, with a rainfall range of 0 to 40 mm / h, and the rainfall is automatically adjustable, with an effective area of ​​2.5 m×2.5 m; ice and snowy environments, where water mist is sprayed at low temperatures to form an ice-covered environment, with an ice thickness of 10 mm / h and a snow thickness of 10 mm / h, and an effective area of ​​2.5 m×2.5 m; strong wind environments, using axial flow fans to generate a wind speed of 0 to 15 m / s. It can also generate coupled environments such as high temperature rain, wind and rain or wind and snow, and low temperature strong winds.

[0066] Data transmission and analysis module: It consists of an electronic computer and a data analysis platform. It receives the gas concentration data collected by the gas monitoring equipment in a wired or wireless manner, and compares and analyzes it with the standard gas concentration.

[0067] (2) Establishing an indicator system

[0068] like Figure 1As shown in the figure, based on the detection indicators of combustible gas detectors in relevant standards and combined with a large number of combustible gas monitor composite environmental adaptability test results, the parameters that are more seriously affected by the composite environment are screened out and classified. Completeness, functionality and security are used as the three major paths (i.e., criterion layers) of the evaluation index system of combustible gas monitors. For each criterion layer, its core indicators are selected, and finally an evaluation index system for the composite environmental adaptability of combustible gas monitors is formed.

[0069] (3) Determine indicator weights

[0070] The target weights of completeness, functionality and security are set as α, β, γ, and determined by hierarchical analysis. The weight vectors of each factor in the factor layer are:

[0071] (4) Calibration of factor layer indicators

[0072] In the factor layer indicator system, there are both qualitative indicators (such as appearance, assembly, self-test function, alarm action function, data display / transmission, waterproof performance, explosion-proof performance) and quantitative indicators (such as range indication deviation, response time, alarm repeatability, concentration detection, power supply stability). These indicators have different value ranges and units. To this end, the qualitative indicators must be quantified first, and then the quantitative indicators must be standardized.

[0073] Assume that after the qualitative indicators are quantified and the quantitative indicators are standardized, for example, the appearance and assembly indicators are x 1 ,x 2 ; Self-check function, alarm action function, range indication deviation, response time, alarm repeatability, data display / transmission, concentration detection 1 ,y 2 ,y 3 ,y 4 ,y 5 ,y 6 ,y 7 ; Waterproof performance, explosion-proof performance, power supply stability 1 ,z 2 ,z 3 .

[0074] a) Quantification of qualitative indicators

[0075] For qualitative indicators, the value 0 to 1 is divided into four intervals, namely [0, 0.4], [0.4, 0.6], [0.6, 0.8], and [0.8, 1], which correspond to four levels = poor, medium, good, and excellent.

[0076] The appearance, assembly, self-test function, alarm action function, data display / transmission, waterproof performance, and explosion-proof performance are graded. As shown in Table 1

[0077] Table 1 Quantitative grading comparison table

[0078]

[0079]

[0080] Note: The middle values ​​of the two levels are 0.9, 0.7, and 0.5 respectively.

[0081] b) Standardization of quantitative indicators

[0082] The standardization of quantitative indicators can be determined by linear interpolation method. The specific steps are as follows:

[0083] 1) Standardize the ideal value of quantitative indicators to 1.00;

[0084] 2) standardize the extremely unsatisfactory values ​​of quantitative indicators to 0.00;

[0085] 3) Use the linear interpolation method to determine the standardized values ​​of the quantitative indicators of this plan.

[0086] The idealized value of each quantitative index can be determined according to the actual situation. Taking the range indication deviation index as an example, it can be considered that when its actual value l is 1% or less, its standard value is 1, and when its actual value is above 5%, its standard value is 0, so that its actual value and standardized value y can be obtained. 3 The piecewise linear function between is:

[0087]

[0088] For the response time indicator, it can be considered that when its actual value l is 10s or less, its standard value is 1, and when its actual value is more than 30s, its standard value is 0, so that its actual value and standardized value y 4 The piecewise linear function between is:

[0089]

[0090] For the alarm repeatability index, it can be considered that when its actual value l is 0.4% or less, its standard value is 1, and when its actual value is above 2%, its standard value is 0, so that its actual value and standardized value y 5 The piecewise linear function between is:

[0091]

[0092] For the concentration detection index, it can be considered that when its actual value l is 1.2% or less, its standard value is 1, and when its actual value is above 5%, its standard value is 0, so that its actual value and standardized value y can be obtained.7 The piecewise linear function between is:

[0093]

[0094] For the power supply stability index, it can be considered that when its actual value l is 2.5% or less, its standard value is 1, and when its actual value is above 5%, its standard value is 0, so that its actual value and standardized value z can be obtained. 3 The piecewise linear function between is:

[0095] Specific implementation method:

[0097] 1) Weight calculation based on AHP method

[0098] like Figure 2 As shown in Table 2, the Analytic Hierarchy Process (AHP) is a hierarchical method for multi-objective combination problems. This method first divides the target problem into multiple levels to form a subordinate structure dominated by superiors and subordinates. An expert group is established to find the maximum eigenvalue and consistency test of each judgment matrix according to the calculation steps and formulas, and finally the evaluation index weights of the combustible gas monitor are obtained as shown in Table 2.

[0099] Table 2 Evaluation index weights of combustible gas monitors

[0100]

[0101]

[0102] 2) Comprehensive evaluation based on value function method

[0103] The value function method is based on the weight of each single evaluation index and the value of the system under the action of the single index, and obtains a comprehensive index by weighting. This method is easy to operate and simple to calculate, and determining the weight is the key point of this method. In order to verify the rationality of this evaluation system, the combustible gas intelligent monitor independently developed by Hefei Zezhong City Intelligent Technology Co., Ltd. was selected for testing, and the environmental adaptability of the gas monitor was evaluated based on the test data. Assuming that the environmental adaptability evaluation index of the gas monitor is F, then:

[0104]

[0105] According to the environmental adaptability evaluation index F of the gas monitor, the evaluation results are divided into four levels, namely excellent, good, general, and poor. The specific classification is shown in Table 3.

[0106] Table 3 Classification standard of environmental adaptability evaluation results of gas monitors

[0107]

[0108]

[0109] Finally, the environmental adaptability evaluation of the gas monitor is shown in Table 4.

[0110] Table 4 Evaluation of environmental adaptability of gas monitor

[0111]

[0112] The results show that the environmental adaptability evaluation score of this type of combustible gas monitor is 0.91 points, which is an "excellent" level, which is consistent with the conclusion of the environmental adaptability test of the combustible gas monitor, proving that the constructed evaluation indicators and comprehensive evaluation method of the combustible gas monitor are reasonable.

[0113] In summary, the present invention innovatively proposes an environmental adaptability evaluation method for combustible gas monitors under complex environments, constructs a combustible gas monitor inspection experimental platform, and uses the AHP-value function method to evaluate and analyze its environmental adaptability, providing a more accurate and comprehensive basis for improving the performance of combustible gas monitors, providing a more powerful guarantee for preventing the occurrence of gas leakage accidents, and providing an important idea and reference for emergency equipment, military equipment and other civilian equipment that require environmental adaptability evaluation and reliability testing, solving the technical problems existing in the prior art that combustible gas monitors cannot be comprehensively evaluated and traditional technologies are not suitable for complex disaster environmental conditions.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents.
