Further, an index early warning threshold value is preset, monitoring data are analyzed, whether the index early warning threshold value is reached or not is judged, and if the index early warning threshold value is not reached, the step S300 is returned to continue to carry out real-time monitoring; and if the index early warning threshold value is reached, responding to the analysis result of the emergency, generating an early warning signal and releasing the early warning signal to public.
Furthermore, the early warning signal is issued to the public mainly by sending the early warning signal to an emergency department or an emergency command mechanism in the local part of the target city, and the emergency department or the emergency command mechanism performs early warning of the emergency within the whole city range of the target city, so that personnel in the target city can know that the emergency occurs in time.
Further, event characteristic information of the emergency event is obtained from the dynamic monitoring data, background judgment of the emergency event suffered by the target city and analysis of a threat environment are carried out, corresponding emergency plans are matched in the emergency plan text database and started based on the event characteristic information, and the event characteristic information comprises the type, the occurrence reason, the related range and the like of the emergency event.
Further, the types of emergency events include four categories of natural disasters, accident disasters, public health events, and social security events. Wherein, the natural disasters mainly comprise flood and drought disasters, meteorological disasters, earthquake disasters, geological disasters, marine disasters, biological disasters, forest and grassland fires and the like; the accident disaster mainly comprises various safety accidents of enterprises such as industrial, mining, commerce and trade, traffic accidents, public facilities and equipment accidents, environmental pollution, ecological destruction events and the like; public health events mainly comprise epidemic situations of infectious diseases, diseases with unknown population causes, food safety and occupational hazards, animal epidemic situations and other events which seriously affect public health and life safety; the social security events mainly comprise terrorist attack events, economic security events, external-related emergencies and the like.

Furthermore, the nearby scheduling of the emergency resources adopts a Geographic Information System (GIS) technology to obtain traffic network information and real-time change conditions in a target area, and then a shortest path algorithm is used to obtain the shortest path between an emergency exit point and a disaster point, so that the nearby scheduling of the emergency resources is realized.
Furthermore, the evacuation scheme is to make an effective population evacuation plan and allocate urban people to refuge based on the information such as the number and spatial distribution of urban residents in the target urban information base, and meanwhile, the evacuation scheme also comprises emergency self-rescue mutual-rescue knowledge, emergency notification, emergency progress, dynamic rescue and the like. The evacuation scheme is mainly used for evacuation guidance of people in three stages of early evacuation, temporary evacuation and emergency evacuation, wherein the early evacuation specifically comprises evacuation guidance of non-primary producers such as old, weak, women and children in cities before or in early stages of emergency occurrence; the temporary evacuation specifically comprises evacuation guidance of emergency commanders who stay in the city when an emergency occurs, rescue professional team personnel and residents who stay in the city and do not have other residential facilities except the city; the emergency evacuation specifically comprises evacuation guidance of people around an emergency occurrence area when the emergency occurs or after the emergency causes large-scale influence.
Furthermore, when the early evacuation stage is in, the evacuation objects in the early evacuation stage are intelligently matched, and an evacuation scheme is sent to the target population, wherein the evacuation scheme provides options of autonomous returning to the country or making close to friends, evacuating towns and towns around the urban area and leaving the city. The resident who selects the option of returning to the country or making close friends submits a specific destination address so as to judge whether the destination belongs to a safe area; the evacuation points matched intelligently according to the principle of near-to-near are provided according to the target city information base in the evacuation scheme adopted by residents who select the option of the evacuation villages and towns around the urban area, the provided evacuation points are only suggestions, and the residents can also independently select from the optional evacuation villages and towns around the urban area under special conditions. And the residents submit the selected evacuation scheme, the evacuation scheme is dynamically adjusted according to the real-time volume of the evacuated people in the surrounding evacuation towns and the number of the accommodated evacuated people in the monitoring data, and once the number of the accommodated evacuated people reaches the capacity limit of an evacuation point, the evacuation point stops receiving the evacuated people and distributes the evacuated people to other evacuation towns according to the principle of proximity.
Furthermore, in the temporary evacuation stage, scientific and reasonable evacuation guidance is conducted on the people staying in the city according to the personnel attributes, the geographic position, the functional types and the capacities of the peripheral civil air defense spaces and the capacity limit-multipath evacuation distribution model. Wherein the capacity limit-multipath dispersion allocation model comprises:

Furthermore, in the emergency evacuation stage, the military or emergency commander carries out evacuation command on the target people according to the real-time monitoring data.
