Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of intelligent building security control, in particular to a safety window intelligent control method, a safety window intelligent control device, an electronic device and a computer readable storage medium. BACKGROUND

[0002] With the progress of science and technology and the continuous iteration of building technology, the functionality and economy of building materials have become an important exploration direction in the construction industry. However, in recent years, explosions and fire accidents caused by gas leakage in homes, hotels, and guesthouses, as well as safety incidents such as combustible / hazardous gas leakage and dust explosion in industrial production and storage links have occurred frequently, posing a serious threat to people's life and property safety and the environment. These accidents highlight the urgent need for intelligent and precise safety control of building environments, especially windows with ventilation or isolation functions, in response to sudden gas / dust hazard risks. How to accurately perceive the concentration of multiple hazardous substances in real time and make reliable control decisions has become a key problem that needs to be solved.

[0003] Currently, existing technologies generally deploy gas / dust concentration sensors at key locations in buildings, such as kitchens and hazardous material warehouses, and compare the detected concentration data with a preset threshold. Once the detection value exceeds the threshold, the preset action (such as closing or opening to a specific angle) of the safety window (or other ventilation equipment) is triggered, in order to isolate the hazard source or enhance ventilation and dilution. This type of solution has achieved monitoring and preliminary response to a single or a few specific hazardous substances to some extent, providing a basic guarantee for building safety.

[0004] However, the prior art still has the following problems: (1) The sensor is easily affected by environmental incidental factors (such as temperature fluctuations, electromagnetic interference, dust coverage), and abnormal data is generated. The prior art lacks effective real-time data credibility verification and abnormal filtering mechanism, resulting in frequent false alarms (false actions when there is no risk) or missed alarms (no action when there is risk) due to false data underestimating the risk, poor control reliability; (2) The decision mainly depends on the simple judgment of whether the single concentration index exceeds the threshold, ignoring the reliability (credibility) of the data itself and the risk superposition effect of the comprehensive action of multiple hazardous substances. Such single-dimensional evaluation is prone to misjudgment (false alarm or missed alarm) when facing complex environments or partial sensor failure, and cannot fully and accurately reflect the real threat state; (3) The control response mode is usually fixed and single, and cannot be flexibly adjusted according to the dynamic changes of data reliability and risk level. This not only may cause unnecessary interference (such as frequent false closing of windows), but also may not take the optimal response measures when the real risk is high but the data is locally abnormal; (4) When some sensors fail or their data credibility is very low, the existing system often cannot effectively use the information provided by other reliable sensors for comprehensive judgment, and is prone to cause the entire system to fail or miss the risk due to local failure, lacking the ability of continuous and stable risk assessment under abnormal conditions.

[0025] Embodiment one Please refer to Figure 1 , Figure 1is a flowchart of the intelligent control method of the safety window provided by the embodiment of the present application, and the method comprises the following steps: S100, obtaining the concentrations of multiple hazardous substances at the current time of the scene where the safety window is located; The safety window refers to a window (which can realize automatic opening and closing function, including but not limited to ordinary window, special window with specific protection function (such as fireproof, anti-theft, anti-falling, explosion-proof, etc.) and the like) which needs to meet the national or industry safety standards in design, and the scene where the safety window is located includes but is not limited to industrial building, public building, residential building and special place.

[0034] S200, performing credibility verification on the concentrations of multiple hazardous substances at the current time of the scene where the safety window is located, to determine the credibility score of the concentrations of multiple hazardous substances at the current time of the scene where the safety window is located; The credibility verification refers to a process of evaluating the authenticity and reliability of the sensor raw data through multi-dimensional physical rules and data logical relationship, and a core target thereof is to identify abnormal data and quantify the credibility thereof, including but not limited to: historical data trend deviation analysis and mutation rate threshold detection.

[0035] Taking the historical data trend deviation analysis as an example, the step S200 comprises: for the concentration of each hazardous substance: Based on the concentration of the current hazardous substance, the credibility score of the concentration of the current hazardous substance is determined by the following formula: ; wherein, represents the credibility score of the concentration of the current hazardous substance at the current time of the scene where the safety window is located, represents the concentration of the current hazardous substance at the current time of the scene where the safety window is located, represents the historical mean of the preset concentration of the current hazardous substance of the scene where the safety window is located, represents the standard deviation of the preset concentration of the current hazardous substance of the scene where the safety window is located.

[0036] Taking the mutation rate threshold detection as an example, the step S200 comprises: for the concentration of each hazardous substance; S1, obtaining the concentration of the current hazardous substance at the last time of the scene where the safety window is located; S2, calculating the difference value of the concentration of the current hazardous substance at the current time and the concentration of the current hazardous substance at the last time of the scene where the safety window is located, to obtain a concentration difference value; S3, calculating the difference value of the current time and the last time of the scene where the safety window is located, to obtain a time difference value; S4, based on the concentration difference value, the time difference value, the preset maximum concentration change rate and the preset attenuation coefficient, the credibility score of the concentration of the current hazardous substance at the current time of the scene where the safety window is located is determined by the following formula: ; wherein, represents the credibility score of the concentration of the current hazardous substance at the current time of the scene where the safety window is located, represents the concentration difference value, represents the time difference value, represents the preset maximum concentration change rate, represents the preset attenuation coefficient.

[0037] S300, determining the weight value of the credibility scores of the concentrations of the plurality of hazardous substances at the current time of the scene where the safety window is located, weighting the credibility scores of the concentrations of the plurality of hazardous substances at the current time of the scene where the safety window is located, and determining the credibility index of the safety window according to the weighting result. In particular, the credibility index of the safety window can be calculated by the following formula: ; wherein, represents the credibility index of the safety window, represents the weight value of the credibility score of the concentration of the flammable gas at the current moment of the scene where the safety window is located, represents the credibility score of the concentration of the flammable gas at the current moment of the scene where the safety window is located, represents the weight value of the credibility score of the concentration of the harmful gas at the current moment of the scene where the safety window is located, represents the credibility score of the concentration of the harmful gas at the current moment of the scene where the safety window is located, represents the weight value of the credibility score of the concentration of the dust at the current moment of the scene where the safety window is located, represents the credibility score of the concentration of the dust at the current moment of the scene where the safety window is located.

[0038] S400, correcting the concentrations of the plurality of harmful substances at the current moment of the scene where the safety window is located; In an embodiment, step S400 comprises: S410, determining that the concentration of the harmful substance at the current moment whose credibility score is less than the preset credibility score is the concentration of the harmful substance to be corrected at the current moment of the scene where the safety window is located; S420, obtaining a preset concentration of the harmful substance to be corrected in the scene where the safety window is located; S430, replacing the concentration of the harmful substance to be corrected at the current moment of the scene where the safety window is located with the preset concentration of the harmful substance to be corrected in the scene where the safety window is located.

[0039] In the present embodiment, by dynamically identifying and replacing the harmful substance concentration data with low credibility (such as abnormal values affected by instantaneous interference), the preset reasonable concentration value is used for correction. This mechanism effectively solves the problem of abnormal data caused by occasional sensor failure or environmental interference, avoids false positives (such as mistakenly opening the window when there is no risk) or false negatives (not responding when there is risk) caused by single-point data distortion, and provides an accurate and anti-interference data basis for subsequent risk index calculation and intelligent control decision-making.

[0040] S500, determining the weight values of the plurality of corrected concentrations of the harmful substances at the current moment of the scene where the safety window is located, weighting the plurality of corrected concentrations of the harmful substances at the current moment of the scene where the safety window is located, and determining the risk index of the safety window according to the weighting result; It should be noted that the use of the concentration parameter of the harmful substance with low credibility in the calculation of the risk index will reduce the accuracy of the risk index, and therefore step S500 selects the corrected concentration of the harmful substance to participate in the calculation of the risk index.

[0041] Specifically, the credibility index of the safety window can be calculated by the following formula: ; wherein, represents the risk index of the safety window, represents the weight value of the concentration of the combustible gas at the current moment of the scene where the safety window is located, represents the concentration of the combustible gas at the current moment of the scene where the safety window is located, represents the weight value of the concentration of the harmful gas at the current moment of the scene where the safety window is located, represents the concentration of the harmful gas at the current moment of the scene where the safety window is located, represents the weight value of the concentration of the dust at the current moment of the scene where the safety window is located, represents the concentration of the dust at the current moment of the scene where the safety window is located.

[0042] S600, according to the credibility index of the safety window and the risk index of the safety window, determining the control mode of the safety window by a preset control mode matrix, and controlling the safety window according to the control mode of the safety window; In an embodiment, according to the credibility index of the safety window and the risk index of the safety window, determining the control mode of the safety window by a preset control mode matrix, comprising: According to the credibility index of the safety window and the risk index of the safety window, determining the control mode of the safety window by a preset control mode matrix, comprising: If the risk index of the safety window is greater than a first preset risk index, determining the control mode of the safety window as an emergency mode; or If the risk index of the safety window is greater than a second preset risk index and less than the first preset risk index, determining the control mode of the safety window as a preventive ventilation mode; or If the risk index of the safety window is less than the second preset risk index, determining the control mode of the safety window as an energy-saving maintenance mode; or If the credibility index of the safety window is less than a preset credibility index, determining the control mode of the safety window as a start diagnosis mode; Wherein, the first preset risk index > the second preset risk index.

[0043] For ease of understanding, the following exemplary gives a preset control mode matrix, as shown in Table 1 below: Table 1 Control mode matrix

[0044] It can be understood that the first preset credibility index, the second preset credibility index, the first preset risk index and the second preset risk index are preset values, and the user can reasonably set them according to actual needs, and the embodiments of the application do not make specific limitations on this.

[0045] The emergency escape mode refers to the highest level emergency response mechanism triggered by the system when the environmental parameter reaches the danger threshold, and the window ventilation is started at the same time, and the fresh air system, the fire ventilation or the heating ventilation system is linked, and the sound and light alarm is sent, and the alarm information is pushed to the system platform and the mobile terminal.

[0046] The preventive ventilation mode refers to that when the monitoring parameter shows potential danger accumulation but does not reach the emergency threshold, the system starts to start the window ventilation, and does not link with the fresh air system, the fire ventilation or the heating ventilation system, but pushes the alarm information to the system platform and the mobile terminal.

[0047] The energy-saving maintenance mode refers to that when the environmental parameter is in the safe range, the system maintains the standby mode.

[0048] The start diagnosis mode refers to the fault handling mechanism triggered by the system when the system detects that the reliability is invalid, and the diagnosis information is pushed to the system platform and the mobile terminal.

[0049] In an embodiment, the safety window is controlled according to the control mode of the safety window, comprising: First step: matching the control mode of the safety window with the pre-constructed safety window control strategy table to obtain the control scheme of the safety window; wherein the pre-constructed safety window control strategy table is used to represent the mapping relationship between different control modes of the safety window and the corresponding control scheme of the safety window; In order to facilitate understanding, the pre-constructed safety window control strategy table is exemplarily given as follows, as shown in Table 2: Table 2 Safety window control strategy table

[0050] Second step: issuing the control scheme of the safety window to the user terminal, so that the user controls the safety window according to the control scheme of the safety window.

[0051] In an embodiment, the control scheme displayed on the user terminal is as follows: Control mode: emergency escape mode; Ventilation instruction: window full open; Linkage instruction: linkage ventilation with the fresh air system, the fire ventilation system and the heating ventilation system; Sound and light emergency alarm: red rotating warning light 120dB buzzer continuous buzzing.

[0052] The beneficial effects of the application are: (1) The application effectively identifies and filters abnormal data generated by accidental interference of the sensor by real-time monitoring of the concentration of various hazardous substances and embedding a credibility verification scoring mechanism, significantly reducing the risk of false positives, and correcting the original data to provide highly accurate and anti-interference basic data for subsequent evaluation.

[0053] (2) The application innovatively combines risk index (evaluating the degree of harm) and credibility index (evaluating the reliability of data) for double evaluation, eliminating the limitations of single index judgment, significantly improving the comprehensiveness and accuracy of the system in judging the environmental threat state, and effectively avoiding misjudgment (false positives or false negatives) caused by single index deviation or unreliable data.

[0054] (3) According to the specific combination relationship of the credibility index and the risk index, the application intelligently and automatically selects the optimal control mode through a pre-set control mode matrix, effectively avoiding false actions (false positives) when there is no risk and missing actions (false negatives) when there is risk, making the safety control response more accurate and reliable.

[0055] (4) Through comprehensive evaluation of multiple hazardous substances, even if some sensors fail or their data credibility is low, the system can still effectively analyze based on the monitoring data of other reliable substances, accurately identify the real comprehensive high-risk state, significantly reduce the possibility of overall system failure or false negatives caused by local faults, and improve the system's continuous risk assessment ability in abnormal situations.
