s100: acquiring first airport monitoring information according to the first airport security management platform;
specifically, the first airport security management platform refers to a platform which is built based on modern information technology, big data and intellectualization and guarantees security and management work in an airport area; the first airport monitoring information refers to information which is acquired by monitoring information acquisition devices distributed at various positions of an airport and is provided for the first airport security management platform to process, and the monitoring information acquisition devices of the monitoring information preferably adopt high-definition intelligent cameras. The first step of building the monitoring system is to call the historical first airport monitoring information and the real-time first airport monitoring information from the first airport security management platform, so as to facilitate subsequent information feedback processing.

S300: obtaining first video information of the first partition;
specifically, the first partition refers to a certain partition after the security management area is partitioned; the first video information refers to real-time monitoring information acquired by a monitoring information acquisition device in the first partition after the partition. The first video information is only real-time monitoring information in the first partition, and is not interfered by monitoring information of other partitions, so that the redundancy of information and data loss in the communication process are reduced, and the accuracy of information acquisition is enhanced.
S400: inputting the first video information into an abnormal behavior analysis model, and acquiring first abnormal behavior information according to the abnormal behavior analysis model;
specifically, the first abnormal behavior information is a screening result of the abnormal behavior of the video information obtained by inputting the first video information into the abnormal behavior analysis model for intelligent analysis, the abnormal behavior analysis model is established on the basis of a neural network model and has the characteristics of the neural network model, wherein the artificial neural network is an abstract mathematical model which is proposed and developed on the basis of modern neuroscience and aims at reflecting the structure and the function of the human brain, the neural network is an operation model and is formed by connecting a large number of nodes (or called neurons) with each other, each node represents a specific output function called an excitation function, the connection between every two nodes represents a weighted value for a signal passing through the connection, called a weighted value, which is equivalent to the memory of the artificial neural network, and the output of the network is in accordance with the connection mode of the network, the abnormal behavior analysis model established based on the neural network model can output accurate first abnormal behavior information, so that the method has strong analysis and calculation capacity and achieves the technical effects of accuracy and high efficiency.
S500: carrying out position marking on an abnormal place according to the first abnormal behavior information to obtain first positioning information;
specifically, the first positioning information refers to that after the first abnormal behavior information concludes that the first video information in the first partition has an abnormal behavior, the position of the abnormal behavior in the first video is defined immediately, and then a specific position determination method is not limited herein according to the position of the first partition corresponding to the position of the abnormal behavior in the first video, because a mature technology exists already. The source of the first abnormal behavior information can be rapidly controlled by acquiring the first positioning information.
S600: performing abnormal video freezing on the first video information through a first video freezing device to obtain a first frozen image;
specifically, the first video freezing device refers to a device that freezes a video clip into a high-definition picture when a high-definition anomaly is extracted from the first video information, and the first video freezing device is, by way of non-limiting example: the convolution can be used as a feature extractor in machine learning, so that extracted feature information has centralization and representativeness, and convolution features of abnormal information of the first video information are further obtained. Further, the first frozen image refers to a result of freezing the abnormal information of the first video information based on the first video freezing device.
S700: judging whether first abnormal information has a first crowd according to the first frozen image;
s800: if the first abnormal information exists in a first aggregation crowd, obtaining a first aggregation scale;
s900: generating a first emergency plan according to the first positioning information and the first aggregation scale;
s1000: and sending the first emergency plan to the first airport safety management platform for emergency treatment.
Specifically, the first crowd refers to a crowd gathering condition at a position where an abnormal condition occurs, which is obtained according to the first abnormal information and the first positioning information after the first frozen image is uploaded; further, the first aggregation scale refers to a basic condition of the first aggregation population obtained by clustering according to the number of people, density, gender, age, and the like of the first aggregation population without any limitation.
Further, different first emergency plans may be screened according to the first aggregation size and the category of the first abnormal information. By way of example and not limitation: if the first abnormal information is the occurrence of fire, the first emergency plan can be used for evacuating people according to the first positioning information, sounding an alarm, alarming, cutting off a propagation source and mobilizing security personnel in an airport to extinguish a fire. And judging whether the number of the dispatched workers is the decision of an evacuation scheme according to the first aggregation scale. The first emergency protocol is optional: in the early stage, a cloud database formed by experience schemes for emergency treatment of various conditions is used, and the first emergency plan is obtained by screening in the cloud database according to the category of the first abnormal information and the first aggregation scale; and in the later period, on the basis that the data volume reaches the trainable intelligent model, a supervised training neural network model is provided, and when the neural network model reaches a convergence state, the first emergency plan with higher individuation degree can be obtained.
Furthermore, because the first abnormal information is determined and the first emergency plan is also finished in the first partition decision, the airport resources can be coordinated and emergency treatment can be carried out only by uploading the first emergency plan to the first airport security management platform. Because the first airport security management platform only needs to coordinate resources to execute the first emergency plan, and other work is completed in the first partition, compared with the prior art, the information transmission process is reduced, each partition makes a decision independently, the redundancy of decision data volume is reduced, and the decision efficiency is improved.
Further, based on the abnormal video freezing of the first video information by the first video freezing device, a first frozen image is obtained, as shown in fig. 2, the method further includes step S1100:
s1110: obtaining a first screening image by screening the first frozen image, wherein the first screening image is an image containing facial features of an abnormal user;
s1120: acquiring first abnormal user information by constructing data of all images in the first screened image;
s1130: acquiring first user identity information according to the first abnormal user information;
s1140: obtaining first historical disease information according to the first user identity information;
s1150: and generating a second emergency plan according to the first historical disease information and the first emergency plan.
Specifically, the first selected image is selected from the first frozen image information to obtain relatively representative image information. Here, the first abnormal information is taken as the indication of the sudden discomfort condition of a person in the first partition, and the first filtered image filtered from the first frozen image includes the image of the facial feature of the abnormal user. Further, the first abnormal user information refers to that based on the facial feature information of the abnormal user, screening can be performed in a large database to obtain basic information of the abnormal user, including but not limited to: age, sex, name, contact information, past disease history, especially heart disease, asthma, etc. The identity information of the first user refers to the information such as the age, the sex, the name, the contact information of relatives and the like; the first history disease information refers to past disease history, especially heart disease, asthma and the like. Furthermore, the first emergency plan is corrected based on the first historical disease information, and the second emergency plan is obtained. The first frozen image is screened to obtain individual information with strong representativeness, and further, the first emergency plan is corrected according to the individual information, and the obtained second emergency plan can comprehensively process abnormal conditions caused by the first abnormal information, for example, priority can be obtained and processed for individuals with special conditions. The technical effect of improving the individualized formulation of the emergency plan is achieved.
Further, based on the obtaining of the first aggregation size if the first abnormal information exists in the first aggregation group, the method step S800 further includes:
s810: according to the first video freezing device, obtaining a second frozen image, wherein the second frozen image is an image of people gathering from a first time node and a second time node;
s820: obtaining a first aggregated population quantity for the first time node;
s830: obtaining a second aggregated population quantity for the second time node;
s840: obtaining a first aggregation index by performing data analysis on the first population of aggregations and the second population of aggregations;
s850: obtaining the first aggregation size based on the first aggregation index.
