The air quality monitoring equipment comprises various gas type wireless detection sensors, air detectors and the like.
As shown in fig. 3, in the method, further, the real-time air data information of each monitoring area is obtained through a digital twin monitoring network, and the real-time air data information of the monitoring area is evaluated to obtain a monitoring area with pathogenic infection risk and a normal area, which specifically includes:

It should be noted that, the local outlier detection algorithm is a local outlier factor algorithm, abbreviated as LOF algorithm, and when the outlier is not greater than the preset outlier, it is indicated that similar data does not exist between the first graph nodes, so that the first graph nodes can be prevented from being repeated, the calculation amount of the model is prevented from being increased, and the calculation complexity of the pathogen type recognition model is optimized. In fact, the environment in which different pathogen types are suitable is inconsistent, and thus inconsistent gas types or gas concentration data may be generated, by which the monitored areas at risk of pathogenic infection as well as normal areas can be more accurately identified. Wherein the air data includes a gas type, a gas concentration corresponding to the gas type, and the like.

It should be noted that, by the method, the propagation priori probability value of each pathogenic type infection occurring in the monitored area with the pathogenic infection risk under the current identification result can be obtained. Since pathogen transmission may be transmitted through a certain transmission medium, such as micro-animals including mosquitoes, flies, worms, etc., the pathogen transmission risk in the monitored area is great when the characteristic data information of the variation in the quantity of the pathogen transmission organism is greater than the characteristic threshold value of the variation in the quantity of the pathogen transmission organism within a preset time. And calculating the transmission priori probability value of each pathogenic infection in the monitoring area with pathogenic infection risk under each identification result through a Markov chain, so as to predict the transmission priori probability value of each pathogenic infection in each monitoring area.
