example 1

[0045] In this example, a deep learning model is constructed in advance based on a large amount of experimental data. The input of the deep learning model is the secondary and derived levels, the initial state data and the initial hazard factor, and the output is the post-action state data.

example 2

[0047] In this example, calculate the initial hazard factor and initial state data according to the preset second algorithm, obtain the current state data of the first level of each hazard-affected body, and judge whether the secondary and derived levels are equal to the level of the current state data , if not equal, then determine the hazard factor of the next level corresponding to the initial hazard factor. Wherein, the preset second algorithm may be the calculation formula mentioned in this example.

[0048] Wherein, in this example, the next-level disaster-causing factors and corresponding probabilities corresponding to each initial disaster-causing factor can be determined, and the next-level disaster-causing factors are generated according to all the disaster-causing factors and corresponding probabilities.

[0049] Furthermore, according to the preset second algorithm, the next-level hazard factor and the current state data are calculated to obtain the next-level deri...

example 3

[0071] In this example, the preset third algorithm is directly constructed, and the formula of the preset third algorithm is shown in the following formula (11), wherein, in the formula (11), Indicates the number of hazards of the next level produced under the current secondary and derivative levels, Indicates the post-action state data of each hazard-bearing body at the next level generated under the current secondary and derived levels, Indicates the probability of hazard-causing factors acting on each hazard-affected body under the current secondary and derivative levels, L and K are ellipsis, A is the action matrix, S i Indicates the state data of the i-th hazard-affected body, a is the secondary and derived level, is the state data after the action of each hazard-bearing body, where, n1 for the first n1 a first-level secondary derivative event, is the total number of secondary derivative events of the first level, for the first n1 The probability of the n2th s...

Abstract

The present invention proposes a method and device for sending early warning information, wherein the method includes: dividing the early warning area into multiple early warning zones, wherein each early warning zone in the multiple early warning zones includes multiple disaster bearing bodies; The initial state data of each hazard-bearing body in the disaster body; obtain the current early warning information, and determine the initial hazard-causing factors corresponding to the early warning information; determine the secondary and derivative levels of disasters corresponding to the current early warning information; according to the preset algorithm and The secondary and derivative levels calculate the initial state data and initial hazard-causing factors to obtain the post-action state data of each hazard-bearing body; determine the early-warning order of multiple early-warning zones according to the post-action state data, and send multiple early-warning Zoning sends current warning information. As a result, the early warning message can be sent to the early warning area most likely to be affected by the disaster in time, the timeliness of sending the early warning information is improved, and the disaster loss is reduced.

Description

technical field [0001] The invention relates to the technical field of information processing, in particular to a method and device for sending early warning information. Background technique [0002] As we all know, timely and effective release of early warning information will buy more preparation time for disasters, and can effectively reduce the impact and loss of disasters. Various early warning information release methods connected to the early warning information release system include: SMS, radio, TV, electronic Display screens, mobile applications, village-level loudspeakers, new media, websites, telephones, Weibo, WeChat, cell broadcasting, faxes, emails, chat software, smart terminals, etc. However, because various information release methods are limited by the performance of the system itself, the information release process needs to last for a certain period of time to complete the full range of information release, and the release of early warning information i...
