Description

Technical Field

[0001] The present invention relates to an early warning service platform, in particular to a village / community-level targeted early warning service platform. Background Art

[0002] In the existing meteorological warning information release system, the release of warning information is usually based on larger administrative units, such as provinces, cities, counties, towns and streets. Although this release method can cover a wide range of audiences, in some special cases, such as extreme weather warnings in local areas, it is difficult for the existing system to accurately release, especially in administrative units at the village level and below, the efficiency and accuracy of warning information dissemination are even more insufficient. In addition, in the existing system, after the warning information is released, it is often communicated to the public through radio, television or mobile phone text messages, lacking accurate notification methods for specific areas and specific groups of people.

[0003] The existing meteorological warning information release system has deficiencies in the following aspects:

[0004] 1. The release scope is not precise enough: The existing system’s warning information release scope is usually limited to county-level or township-level units, and cannot be accurate to the administrative areas at the village level and below. This extensive warning information release method may result in some remote or small-scale residents being unable to receive warning information in a timely manner, especially for managers at the village / community level. It is difficult to quickly obtain effective information for emergency response.

[0005] 2. Lack of targeted notification capabilities: The current warning information release system is mostly widely disseminated, and cannot achieve targeted notification for a specific small range or specific managers. For example, in the face of sudden weather events, the system cannot quickly and accurately notify the relevant managers at the village level, but instead notifies all grassroots flood prevention responsible persons in the form of mass notification. This kind of flood-covering notification form has many empty reports, which is not conducive to precise prevention and can easily reduce the credibility of the meteorological department's warning signals.

[0006] 3. Low efficiency of information transmission: Since early warning information often needs to be transmitted through multiple levels before it reaches the grassroots management personnel, the efficiency of information transmission is low and there is a problem of information delay, which may affect the emergency response speed of the village / community level. In addition, when editing the early warning information service, the forecaster must carefully check the affected area on the map and check and write it one by one. If there are many towns and streets affected, it will further affect the timeliness of the release. Summary of the invention

[0007] The technical problem to be solved by the present invention is to provide a village / community-level targeted early warning service platform that can transmit early warning information in a timely and accurate manner and accurately notify managers of administrative areas at the village / community level, thereby increasing the efficiency of emergency response.

[0008] The technical solution adopted by the present invention to solve the above technical problems is: a village / community-level targeted early warning service platform, including a GIS data preparation and encoding module, a management personnel information integration module, a region selection module and an early warning information sending module.

[0009] The GIS data preparation and encoding module is used to generate a GIS geographic data map and uniquely encode all administrative regions in the GIS geographic data map down to the village / community level, so that each administrative region in the GIS geographic data map has a unique code;

[0010] The management personnel information integration module is used to store the communication information of the management personnel corresponding to each administrative area, and associate the communication information of the management personnel with the code of the corresponding administrative area to form a regional management information lookup table;

[0011] The area selection module is used to select the warning area on the GIS geographic data map. The area selection module is preset with an area selection box with adjustable shape. When the user selects the warning area on the GIS geographic data map through the area selection box, the area selection module performs spatial analysis on the GIS geographic data map based on the shape of the area selection box, identifies the administrative area within the coverage of the warning area and obtains the corresponding code, and then sends the obtained code to the warning information sending module;

[0012] The warning information sending module is used to read the communication information of the management personnel associated with the code of the administrative area within the coverage of the warning area from the regional management information lookup table, and send the warning information to the communication terminal of the associated management personnel.

[0013] Compared with the prior art, the advantage of the present invention is that in the targeted early warning service platform, a GIS geographic data map is generated by using the existing GIS map drawing tool and all administrative regions in the GIS geographic data map down to the village / community level are uniquely coded, laying the foundation for the subsequent correlation between the communication information and the coding of the management personnel, and then the communication information of the management personnel is correlated with the coding of the corresponding administrative region to form a regional management information lookup table, so as to prepare for the subsequent sending of early warning information within the early warning region; the user selects the early warning region on the GIS geographic data map through the region selection box with adjustable shape in the region selection module, the region selection module identifies the administrative region within the coverage of the early warning region and sends the corresponding coding to the early warning information sending module, and finally the early warning information sending module sends the early warning information to the communication terminal of the associated management personnel;

[0014] By encoding the administrative areas, the present invention realizes the efficient correspondence and call of the communication information of the managers and the administrative areas to which they belong. When the user selects the early warning area, the system can automatically list the communication information of the administrative areas such as districts, counties, towns, streets and villages / communities and their managers within the early warning area, and the retrieval is more efficient and convenient; the targeted early warning service platform can send the early warning information to the communication terminals of the managers in the selected early warning area in real time, ensuring the timeliness and accuracy of information transmission, improving the efficiency of emergency response, and the managers of village / community-level units can quickly obtain effective early warning information to carry out emergency handling and carry out precise prevention; the communication terminals include but are not limited to conventional communication equipment such as mobile phones and computers, and the early warning information is common communication information such as text messages, telephone messages, broadcasts, and information in communication software.

[0015] Specifically, the data of each administrative region in the GIS geographic data map corresponds to the administrative division data disclosed in the National Geographic Information Public Service Platform, and the administrative division data includes district and county level vector data, township and street level vector data, and village / community level vector data.

[0016] Specifically, the GIS data preparation and coding module adopts a hierarchical coding method to uniquely code administrative regions, and sets a unique code for each administrative region during the unique coding process, so as to facilitate and accurately notify administrative regions at all levels and corresponding managers.

[0017] Specifically, the regional management information search table is provided with a manager name information column, a unit message column, a contact information column, and a jurisdiction area information column, wherein the jurisdiction area information column stores the code of the administrative area associated with each manager. In this way, the manager is associated with the code of the administrative area and uniformly stored in the database, supporting fast retrieval and call.

[0018] Specifically, the region selection module performs spatial analysis on the GIS geographic data map based on the shape of the region selection box, and identifies the administrative regions within the coverage of the warning region in the following specific process:

[0019] Step (1): Define the polygon formed by the boundaries of each administrative region on the GIS geographic data map as a boundary polygon. The region selection module obtains the minimum enveloping quadrilateral of the region selection box and the minimum enveloping quadrilateral of the boundary polygon. Then, the minimum enveloping quadrilateral of the region selection box and the minimum enveloping quadrilateral of the boundary polygon are subjected to collision detection. The boundary polygon whose minimum enveloping quadrilateral collides with the minimum enveloping quadrilateral of the region selection box is taken as the initial screening result.

[0020] Step (2): Obtain the coordinates and range of each vertex of the area selection box, and add the boundary polygons in the primary screening results that contain any vertex of the area selection box to the secondary screening results; extract the boundary point coordinates of the remaining boundary polygons in the primary screening results, and continue to add the boundary polygons whose boundary point coordinates are within the range of the area selection box to the secondary screening results;

[0021] Step (3): perform collision detection on each edge of the remaining boundary polygon in the primary screening result and each edge of the region selection box to determine whether the edge of the boundary polygon intersects with the edge of the region selection box, and add any boundary polygon whose edge intersects with any edge of the region selection box to the secondary screening result;

[0022] Step (4): The administrative area corresponding to the boundary polygon in the final secondary screening result is used as the administrative area within the coverage of this warning area. Allowing users to independently select warning areas through circles, rectangles or irregular polygons, and finally obtain accurate administrative area selection results through secondary screening, achieving accurate coverage of the village / community level, and preventing the warning information from being too wide or insufficient in coverage.

[0023] Specifically, the shape of the area selection frame includes a circle, a rectangle and an irregular polygon.

[0024] Specifically, the warning information sending module includes a short message template prefabrication module, a warning information generation module and a real-time information sending module.

[0025] The SMS template prefabrication module prefabricates corresponding warning SMS texts according to different disaster levels and different disaster weather types and stores them in the warning SMS text prefabrication set, and then uses the disaster weather type and disaster level as keywords to establish a retrieval index for the warning SMS text prefabrication set; the SMS template prefabrication module provides a variety of modifiable warning information templates, allowing users to flexibly set warning information according to specific needs, significantly improving practicality and warning efficiency;

[0026] The warning information generation module retrieves the corresponding warning text from the prefabricated warning text set according to the disaster weather type and disaster level input by the user according to the search index and automatically generates a matching warning text;

[0027] The real-time information sending module sends the warning SMS to the communication terminal of the associated manager in real time through the SMS gateway and monitors the sending status, ensuring that the information arrives in time and feeding back the sending result. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Figure 1 It is a structural principle block diagram of the present invention. DETAILED DESCRIPTION

[0029] The present invention is further described in detail below with reference to the accompanying drawings.

[0030] like Figure 1 As shown in FIG. 1 , a village / community-level targeted early warning service platform includes a GIS data preparation and coding module, a management personnel information integration module, a region selection module, and an early warning information sending module.

[0031] The GIS data preparation and coding module is used to generate a GIS geographic data map and uniquely code all administrative regions in the GIS geographic data map down to the village / community level, so that each administrative region in the GIS geographic data map has a unique code. The data of each administrative region in the GIS geographic data map corresponds to the administrative division data disclosed in the National Geographic Information Public Service Platform. The administrative division data includes district and county level vector data, township and street level vector data, and village / community level vector data. The GIS data preparation and coding module uses a hierarchical coding method to uniquely code administrative regions. In the process of unique coding, a unique code is set for each administrative region. For example, the code of a village is "1010203", where the first digit "1" represents the city-level code to which the village belongs, the second and third digits "01" are the district and county code to which the village belongs, the fourth and fifth digits "02" represent the township and street code to which the village belongs, and the sixth and seventh digits "03" are the identification code of the village.

[0032] The manager information integration module is used to store the communication information of managers corresponding to each administrative region, and associate the communication information of managers with the codes of the corresponding administrative regions to form a regional management information search table; the regional management information search table is provided with a manager name information column, a unit message column, a contact information column, and a jurisdiction area information column, wherein the jurisdiction area information column stores the code of the administrative region associated with each manager. In this way, the manager and the administrative region code are associated and uniformly stored in the database, supporting fast retrieval and call.

[0033] The area selection module is used to select the warning area on the GIS geographic data map. The area selection module is preset with an adjustable area selection box. The shapes of the area selection box include circle, rectangle and irregular polygon. When the user selects the warning area on the GIS geographic data map through the area selection box, the area selection module performs spatial analysis on the GIS geographic data map based on the shape of the area selection box, identifies the administrative areas within the coverage of the warning area and obtains the corresponding codes, and then sends the obtained codes to the warning information sending module; the user selects the circular, rectangular or irregular polygon area selection box with the mouse and adjusts it to delineate the warning area. The area selection module automatically lists the administrative areas within the range, including districts, counties, towns, streets and villages / communities, and identifies the codes of all administrative areas included in the warning area.

[0034] Specifically, the region selection module performs spatial analysis on the GIS geographic data map based on the selected shape, and identifies the administrative regions within the coverage of the warning area. The specific process is as follows:

[0035] Step (1): Define the polygon formed by the boundaries of each administrative region on the GIS geographic data map as a boundary polygon. The region selection module obtains the minimum enveloping quadrilateral of the region selection box and the minimum enveloping quadrilateral of the boundary polygon. Then, the minimum enveloping quadrilateral of the region selection box and the minimum enveloping quadrilateral of the boundary polygon are subjected to collision detection. The boundary polygon whose minimum enveloping quadrilateral collides with the minimum enveloping quadrilateral of the region selection box is taken as the initial screening result.

[0036] Step (2): Obtain the coordinates and range of each vertex of the area selection box, and add the boundary polygons in the primary screening results that contain any vertex of the area selection box to the secondary screening results; extract the boundary point coordinates of the remaining boundary polygons in the primary screening results, and continue to add the boundary polygons whose boundary point coordinates are within the range of the area selection box to the secondary screening results;

[0037] Step (3): perform collision detection on each edge of the remaining boundary polygon in the primary screening result and each edge of the region selection box to determine whether the edge of the boundary polygon intersects with the edge of the region selection box, and add any boundary polygon whose edge intersects with any edge of the region selection box to the secondary screening result;

[0038] Step (4): The administrative area corresponding to the boundary polygon in the final secondary screening result is used as the administrative area within the coverage of the identified warning area. Since the shapes of village / community-level administrative areas on the GIS geographic data map are relatively diverse, and the boundaries between them are mostly irregular curves, polylines, etc., if conventional rectangular or circular area selection boxes are used, it is often easy to cause missed selections or multiple selections, resulting in inaccurate notifications; using the above secondary screening results greatly improves the accuracy of the selected village / community-level administrative areas, ensuring that the warning message can be accurately delivered to the relevant management personnel.

[0039] The warning information sending module is used to read the communication information of the management personnel associated with the code of the administrative area within the coverage of the warning area from the regional management information lookup table, and send the warning information to the communication terminal of the associated management personnel; specifically, the warning information sending module includes a short message template prefabrication module, a warning information generation module and a real-time information sending module;

[0040] The SMS template prefabrication module prefabricates the corresponding warning SMS texts according to different disaster levels and different disaster weather types and stores them in the warning SMS text prefabrication set. The SMS template prefabrication module provides customized settings for warning SMS to ensure that SMS can be sent quickly and accurately. Disaster weather types include heavy rain, lightning, strong winds, etc., and disaster levels include yellow warning, orange warning, and red warning, etc. Then, the disaster weather type and disaster level are used as keywords to establish a retrieval index for the warning SMS text prefabrication set to ensure the rapid acquisition of warning information. The keywords are: "short-term heavy precipitation yellow", "strong lightning red warning", "lightning activity yellow warning", etc.

[0041] When the keyword is "yellow warning for lightning activity", the corresponding complete warning SMS text is as follows:

[0042] "Thunder and lightning warning: Affected by strong convective clouds, lightning activity is expected to occur in "a certain area" within 30 minutes. The Meteorological Observatory has issued a yellow warning for thunderstorms. Please pay attention to prevent the adverse effects of strong convective weather on transportation, agriculture, etc. Issued by the "such and such" Meteorological Observatory at 16:51 on October 16." Among them, "a certain area" and "such and such" Meteorological Observatory can be filled in according to actual conditions.

[0043] The warning information generation module retrieves the corresponding warning SMS text from the warning SMS text prefabricated set according to the disaster weather type and disaster level input by the user based on the search index and automatically generates a matching warning SMS; this module ensures that the warning information can accurately reflect the specific meteorological conditions and prepares the content for the subsequent sending link.

[0044] The real-time information sending module sends the warning SMS to the communication terminal of the associated manager in real time through the SMS gateway and monitors the sending status to ensure that the information arrives in time and feedback the sending results.

[0045] When establishing a village / community-level targeted early warning service platform for the target area, three parts need to be improved: 1) geographic information data that can be used for user selection, that is, the administrative area data of the target area, and unique coding to ensure the uniqueness of the code of each administrative area; 2) personnel data, mainly involving the contact information of the managers who receive the early warning information, and storing the code of the administrative area associated with each manager in the information column of the area under the jurisdiction of each manager; 3) pre-production of early warning SMS texts, that is, according to different disaster levels and disaster weather types, set the corresponding early warning SMS texts to form a pre-made set of early warning SMS texts.
