[0002] Gas detectors play an important role in industrial safety, environmental monitoring and other fields, but their detection accuracy is often affected by complex environmental factors (such as temperature and humidity fluctuations). The existing technology has the following shortcomings: Traditional gas detectors mostly use linear compensation models (such as fixed coefficient compensation), which makes it difficult to accurately characterize the nonlinear characteristics of temperature and humidity coupling. For example, in high temperature and high humidity environments, the cross-sensitivity effect of sensors is significant, resulting in increased compensation errors and higher false alarm rates.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Example 1

[0025] Reference Figure 1 , which is the first embodiment of the present invention, provides a method for optimizing the environmental adaptability of an intelligent gas detector, comprising the following steps: S1. Obtain the gas concentration signal, temperature signal and humidity signal in the monitored environment in real time through the intelligent gas detector.

[0026] In an optional embodiment, in a chlorine storage tank area of ​​a chemical plant, the environmental parameter range is: Temperature: -20℃ to 50℃ (extreme temperatures from winter to summer); Humidity: 20%RH to 90%RH (dry environment to steam environment); Target gas: chlorine (Cl2), safety threshold 1ppm (OSHA standard).

[0027] S2. Perform temperature-humidity coupling compensation on the gas concentration signal to obtain a calibrated gas concentration value.

[0028] Gas concentration values ​​can be obtained by: A temperature range interval and a humidity range interval are established respectively through the temperature signal and the humidity signal, and the temperature range interval and the humidity range interval are divided into a plurality of small areas respectively; For example, the two-dimensional space of temperature and humidity is divided into N small areas, each of which is represented as: , where R represents a set of small regions, i represents the i-th small region, and Represent the temperature signal and humidity signal of the i-th small area respectively.

[0029] Each small area corresponds to a dynamic domain compensation formula, which is expressed as: ; In the formula, and and are expressed as polynomial compensation coefficients in the i-th region, which are used to fit the linear and nonlinear effects of temperature and humidity on gas concentration; It is expressed as the amplitude coefficient of the exponential term, which controls the intensity of the temperature and humidity coupling effect; It is expressed as an exponential decay coefficient, which determines the influence range of the temperature and humidity product term (for example, the larger the λ, the faster the coupling effect decays with changes in temperature and humidity); and Respectively represent the calibration reference temperature and humidity; It is expressed as the calibrated gas concentration value in the i-th area; Expressed as raw concentration signal.

[0030] The environmental status is monitored in real time, the membership of different small areas is calculated, and the top three small areas with the highest membership are selected for compensation result fusion to finally obtain the calibrated gas concentration value.

[0031] Real-time detection of environmental status , calculate its membership to each region: ; In the formula, is the degree of membership of region i, is the centroid coordinate of region i, and All are shape factors; Select the top three regions of membership to fuse the compensation results: ; In the formula, is the calibrated gas concentration value.

[0032] In this embodiment, a situation experiment can be selected. First of all, it is necessary to know that the temperature range is -40℃ to 85℃, and the gradient test points include -40℃, -20℃, 0℃, 25℃ (benchmark), 50℃, 70℃, and 85℃; the humidity range is 10%RH to 90%RH, and the gradient test points include 10%, 30%, 50% (benchmark), 70%, and 90%RH. Therefore, there are 35 temperature and humidity combinations (7 temperature points × 5 humidity points).

[0033] The temperature and humidity space is divided into 9 areas (3×3 grid): the temperature zones are -40℃~15℃, 15℃~50℃, and 50℃~85℃; the humidity zones are 10%~40%RH, 40%~70%RH, and 70%~90%RH.

[0034] Taking the high temperature and high humidity area (50℃~85℃, 70%~90%RH) as an example, the compensation parameters after calibration are: =0.0023, =-0.00015, =1.2*10 -6 ; =0.0018, =-0.00008; =0.05; =0.012; =25℃, =50%RH.

[0035] Later, during the test, the detector was calibrated to output 100ppm (error ±0.5ppm) in a standard environment of 25°C and 50%RH; For the first scene of low temperature and dryness (-40℃, 10%RH), the original signal = 132.4ppm (significantly affected by low temperature), the matching area is the low temperature and low humidity area (membership 0.85) and the adjacent area (membership 0.12, 0.03), and the result after compensation is 100.8ppm, with an error of +0.8%FS.

[0036] For the second scenario of high temperature and high humidity (85°C, 90%RH), the original signal = 78.6ppm (high temperature and high humidity cause the sensor sensitivity to decrease), the matching area is the high temperature and high humidity area (membership 0.92) and the adjacent area (membership 0.06, 0.02). After compensation, the result is 99.2ppm, with an error of -0.8%FS.

[0037] For the sudden change of temperature and humidity in the third scenario (temperature rises suddenly from 25℃ to 70℃, and humidity drops from 50%RH to 20%RH), the original signal fluctuates between 85~115ppm. After dynamic fusion of membership and compensation, it stabilizes at 98~102ppm, with a maximum instantaneous error of ±2%FS.

[0038] Table 1: Experimental diagram of different test conditions

[0039] It can be seen from Table 1 that within the range of -40℃~85℃, the maximum error of this embodiment is ±2.4%FS, which is significantly better than the ±8.7%FS of the traditional linear model, and the error is reduced by 72.4%. In the extreme high temperature and high humidity scenario (85℃, 90%RH), the compensation error is only -0.8%FS, which is 94.7% higher than the traditional model (-15.2%FS).

[0040] The compensation parameters of each area are calibrated offline through the quantum particle swarm algorithm (QPSO), and the training data covers the full temperature and humidity range.

[0041] S3. Calculate the correlation weights of the temperature signal, humidity signal and gas concentration value to generate an environmental factor impact matrix.

[0042] The steps to obtain the environmental factor impact matrix include: Define the time window length as L seconds, and generate a continuous historical data sequence stored in the window; Among them, the continuous historical data sequence stored in the window includes , and , where T is the temperature sequence, H is the humidity sequence, and C is the gas concentration sequence; Obtain temperature correlation calculation formula and humidity correlation calculation formula; The temperature correlation calculation formula is expressed as: ; The humidity correlation calculation formula is expressed as: ; in, and They are respectively represented as temperature correlation and humidity correlation, and L represents the length of the defined time window. , and The average values ​​of temperature, humidity and concentration in the window are represented respectively; Then the temperature correlation calculation formula and the humidity correlation calculation formula are processed, and finally the environmental factor influence matrix is ​​output.

[0043] The temperature correlation calculation formula and humidity correlation calculation formula are processed and expressed as: ; ; In the formula, and They are respectively expressed as the weight of temperature influence and the weight of humidity influence; The output environmental factor impact matrix is ​​expressed as: ; Where M is represented as a 1×2 matrix.

[0044] S4. Determine whether the change in gas concentration value is caused by non-environmental factors through the environmental factor impact matrix.

[0045] When judging whether the change in gas concentration value is caused by non-environmental factors, the following steps are included: Preset multi-level concentration thresholds, compare the gas concentration value with the multi-level concentration thresholds, and generate an early warning signal based on the comparison results; The warning signal is matched with the corresponding control strategy and the operation is executed through the intelligent gas detector.

[0046] When the change in gas concentration value is caused by non-environmental factors, an early warning signal is generated by comparing the results; Among them, the warning signals include level one warning, level two warning and level three warning; The judgment condition for the first-level warning is that the change gradient of the gas concentration value is within the first-level interval; The judgment condition for the second-level warning is that the change gradient of the gas concentration value is within the second-level interval; The judgment condition for the third-level warning is that the change gradient of the gas concentration value is within the third-level interval.

[0047] The setting methods of the first-level interval, the second-level interval and the third-level interval include: Preset standard concentration value Q; The adjacent intervals of the standard concentration values ​​are output as the first-level intervals, that is, the first-level intervals are expressed as: (Q-α, Q+α); The adjacent intervals of the first-level interval are output as the second-level intervals, that is, the second-level intervals are represented as: (Q-α-β, Q-α] and [Q+α, Q+α+β); The adjacent intervals of the second-level interval are output as the third-level intervals, that is, the third-level intervals are expressed as: [Q-α-β-γ, Q-α-β] and [Q+α+β, Q+α+β+γ].

[0048] In this embodiment, for example, the preset standard concentration value Q is 1ppm, and α=0.2ppm, β=0.3ppm, and γ=0.5ppm are set for the gas. Therefore, the first-level interval output by setting is expressed as: (0.8, 1.2), the second-level interval is expressed as: (0.5, 0.8] and [1.2, 1.5), and the third-level interval is expressed as: [0, 0.5] and [1.5, 2]; Then, tiny pipeline leakage (slow diffusion) and valve rupture (sudden leakage) were simulated, and the detector was configured with a sampling frequency of 1 time / second and an early warning response delay of ≤0.5 seconds.

[0049] In one scenario, a slow leak (level 1 warning), i.e., a leakage rate of 0.05ppm / s, a concentration change of t=8s: 1.4ppm, enters the upper limit of the level 1 interval of 1.2ppm, triggering a level 1 warning, activating the local sound and light alarm, and displaying a yellow warning sign in the central control room.

[0050] In another scenario, a moderate leak (secondary warning), that is, the leakage rate is 0.25ppm / s, the concentration change t=3s: 1.75ppm, entering the upper limit of the secondary interval of 1.5ppm, triggers the secondary warning, activates the ventilation system (air volume increased to 80%), and sends a text message to the security administrator.

[0051] In the third scenario, a sudden leak (level three warning), that is, the leakage rate is 0.8ppm / s, the concentration change t=1.25s: 2ppm, entering the upper limit of the level three interval 2ppm, triggering the level three warning, emergency shut-off of the upstream valve (response time 0.3 seconds), starting the spray suppression system, and uploading the alarm information to the emergency management platform.

[0052] In summary, the temperature and humidity space is divided into multiple areas to accurately capture the synergistic effect of temperature and humidity. Experiments show that within a wide temperature range of -40°C to 85°C, the compensation error is ≤±3%FS, which is 40% higher than the traditional linear model. Through fuzzy calculation, the adjacent areas are matched in real time to eliminate the mutation error caused by hard boundaries, and the error is reduced by 32% in the humidity mutation (ΔH>20%RH / min) scenario.

[0053] The influence of non-environmental factors is comprehensively determined by combining time domain residual statistics, frequency domain principal component analysis and environmental weight matrix. For example, when the frequency domain amplitude ratio is >5:2:1, the high-frequency characteristics of sudden leakage can be specifically identified, and the false alarm rate is reduced from 25% to 8%. The threshold is calculated based on real-time data and adaptively adapts to environmental baseline drift to avoid false alarms during the day and night caused by fixed thresholds.
