Description
Technical Field
[0001] The present invention relates to the technical field of microbial transmission risk early warning, and particularly relates to a real-time early warning system and method for indoor microbial transmission risk. Background Art
[0002] Infectious diseases are transmitted through ways such as air and contact. The indoor environment has become a high-risk area for transmission. The air quality of the indoor environment is affected by various factors, including poor air fluidity, poor ventilation, and pollution sources. Microorganisms such as molds and bacteria can rapidly reproduce and spread in these environments, affecting people's health. With the development of the Internet of Things technology, potential microbial transmission risks can be predicted through means such as sensors and data acquisition devices. Therefore, the research on a real-time early warning system for indoor microbial transmission risk is necessary.
[0003] In the prior art, real-time early warning of indoor microbial transmission risk can meet certain requirements, but there are also some potential risks. Specifically: on the one hand, the utilization of monitoring data for each time period within each historical monitoring cycle is insufficient, ignoring the different monitoring requirements for each time period behind the data, using the same data monitoring frequency, resulting in a large amount of redundant monitoring data, increasing the workload of the early warning system and wasting work resources, and reducing the stability of the early warning system. On the other hand, the prior art ignores the analysis of the potential impact of air environment data and personnel activity data on microbial transmission risk, making it difficult to effectively analyze the impact of air environment and personnel activities on the living space of microorganisms, resulting in insufficient early warning of microbial transmission risk and difficulty in meeting the actual monitoring and early warning requirements.

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0042] Embodiment 1:
[0043] Refer to Figure 1As shown in the figure, the first aspect of the present invention provides a real-time warning system for indoor microbial transmission risk. The system includes: a monitoring and preprocessing module, which is used to extract the indoor microbial transmission risk index within each time period during the historical monitoring period from the database, divide the monitoring requirement levels of each time period, and set the data collection frequency corresponding to each monitoring requirement level time period.
[0044] In a specific embodiment of the present invention, for dividing the monitoring requirement levels of each time period and setting the data collection frequency corresponding to each monitoring requirement level time period, the specific analysis method is as follows:
[0045] The indoor microbial transmission risk indexes within each time period during each historical monitoring period are respectively subjected to mean processing to obtain the average indoor microbial transmission risk index αi within each historical time period, where i = 1, 2,..., n, i represents the number of each time period, and n represents the total number of time periods within the monitoring period.
[0046] It should be noted that in a specific embodiment, the calculation method of the average indoor microbial transmission risk index within each historical time period is specifically: based on the indoor microbial transmission risk indexes within each time period during each historical monitoring period where c = 1, 2,..., y, c represents the number of each historical monitoring period, and y represents the total number within the historical monitoring period. Through the formula: The average indoor microbial transmission risk index αi within each historical time period is calculated.
[0047] It should be noted that in a specific embodiment, each monitoring period is, for example, one day, and each time period is composed of different monitoring time intervals within one day.
[0048] Through the formula: The monitoring requirement level judgment value κi of each time period is obtained, where α′ represents the judgment threshold of the indoor microbial transmission risk index extracted from the database.
[0049] If κi = 1, it is determined that the monitoring requirement level of the i-th time period is a high requirement, and the collection frequencies of the air environment data, personnel activity data, and microbial data in the i-th time period are set to the first collection frequency extracted from the database.
[0050] If κi = 0, it is determined that the monitoring requirement level of the i-th time period is a low requirement, and the collection frequencies of the air environment data, personnel activity data, and microbial data in the i-th time period are set to the second collection frequency extracted from the database.
[0051] It should be noted that in specific embodiments, the first data collection frequency and the second data collection frequency are manually set by technicians considering different monitoring requirement levels comprehensively. For example, when the monitoring requirement level in the i-th time period is high, the data collection frequency F in the i-th time period is set to 2H; when the monitoring requirement level in the i-th time period is low, the data collection frequency F in the i-th time period is set to H.
[0052] The present invention divides the monitoring requirement levels of each time period and sets the data collection frequencies corresponding to the time periods of each monitoring requirement level, effectively avoiding the redundancy of a large amount of monitoring data, saving the working resources of the indoor microbial transmission risk real-time warning system, improving the working efficiency of the indoor microbial transmission risk real-time warning system, and ensuring the working stability of the indoor microbial transmission risk real-time warning system.
[0053] The air environment data collection and analysis module is used to collect various data of the indoor air environment in the target time period and calculate the indoor air environment influence coefficient in the target time period.

[0055] In a specific embodiment of the present invention, for the calculation of the indoor air environment influence coefficient in the target time period, the specific analysis method is as follows: based on the ambient temperature, ambient humidity, and carbon dioxide concentration at each collection point in the target time period, an air environment data set Djk at each collection point in the target time period is formed, where j = 1, 2,..., m, j represents the number of each parameter of the air environment data set, m represents the total number of parameters of the air environment data set, k = 1, 2,..., q, k represents the number of each collection point, and q represents the total number of collection points.

[0057] It should be noted that in a specific embodiment, the calculation method of the abnormal judgment value of each parameter of the air environment data set at each collection point within the target time period is determined by combining whether each parameter of the air environment data set at each collection point within the target time period is within the standard interval of each parameter of the air environment data set. If it is within the standard interval of each parameter of the air environment data set, the abnormal judgment value of each parameter of the air environment data set is set to 0. If it is not within the standard interval of each parameter of the air environment data set, the abnormal judgment value of each parameter of the air environment data set is set to 1.
[0058] Through the formula: The indoor air environment influence coefficient λ within the target time period is calculated.

[0061] It should be noted that in a specific embodiment, the indoor pedestrian flow within the target time period refers to the number of people who have entered and exited the indoor space within the target time period by performing image recognition through a camera device. The average stay duration of personnel within the target time period is obtained by statistically analyzing the stay duration ts of each person who has entered and exited the indoor space through image recognition technology, where s = 1, 2,..., w, s represents the number of each person who has entered and exited the indoor space, and w represents the total number of people who have entered and exited the indoor space. Through the formula: The average stay duration t of personnel within the target time period is calculated.
[0062] The number of high-density areas of personnel within the target time period is calculated through a camera device and image recognition. The U area region is extracted from the database as the judgment region space. If the number of people in the U area region is greater than the number E, it is determined as a high-density area of personnel, where E represents the personnel quantity judgment threshold of the crowded area extracted from the database.
[0063] In a specific embodiment of the present invention, the specific analysis method for calculating the indoor personnel activity influence coefficient within the target time period is as follows: Combine the indoor pedestrian flow, the average personnel stay duration, and the number of high-density personnel areas within the target time period to form a personnel activity data set Ra within the target time period, where a = 1, 2, …, x, a represents the numbering of each parameter of the personnel activity data set, and x represents the total number of parameters of the personnel activity data set. Through the formula: Calculate the indoor personnel activity influence coefficient ρ within the target time period, where σa represents the unit influence factor of each parameter of the personnel activity data set extracted from the database.
[0064] It should be noted that in a specific embodiment, the specific calculation method for the indoor personnel activity influence coefficient within the target time period is obtained by considering the influence factor of the indoor pedestrian flow and the unit indoor pedestrian flow, the influence factor of the average personnel stay duration and the unit average personnel stay duration, and the influence factor of the number of high-density personnel areas and the number of high-density personnel areas for analysis.
