[0040] The following is a detailed description of the embodiments of the technical strategy of the present invention in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical strategy of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.

[0041] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by those skilled in the art to which the invention belongs.

[0042] Example 1

[0043] like Figure 1 As shown, an embodiment of the present invention provides an emergency resource scheduling and management system based on fusion communication visualization technology, the system comprising:

[0044] The data acquisition module is used to determine the place where the emergency event occurs as the destination for emergency resource dispatch and display the destination on an electronic map, obtain the distribution of dispatch points around the destination, and display the distribution on an electronic map, wherein the distribution includes the location of the dispatch point and the types and quantities of dispatchable emergency resources.

[0045] A strategy determination module is used to combine the scheduling points according to the types and quantities of the dispatchable emergency resources to obtain a scheduling area; enumerate all possible paths with the number of scheduling points as the first constraint and the value of the emergency resources as the second constraint; calculate the comprehensive cost of the possible paths, determine the optimal path and generate an emergency scheduling strategy;

[0046] The visual dispatch module is used to execute the emergency dispatch strategy and display the execution status of the emergency dispatch strategy on an electronic map.

[0047] In the present invention, the data acquisition module includes: an initialization unit, used to predict the types and quantities of initial schedulable resources based on the historical events in the scheduling area; a correction unit, used to determine the propagation efficiency of the emergency event according to the event type, and determine the emergency resource penalty value according to the scheduling time constraint, propagation efficiency and the distance between the scheduling point and the destination; the types and quantities are corrected according to the emergency resource penalty value to obtain the types and quantities of schedulable resources.

[0048] The work of the initialization unit is to predict the types and quantities of initial dispatchable resources based on the historical events in the dispatch area. This involves in-depth analysis of historical data to identify common emergency types, their frequency of occurrence, and the types and quantities of resources required. By applying techniques such as statistical analysis and machine learning, the initialization unit can predict emergency events that may occur within a certain period of time, and accordingly predict the initial dispatchable resource requirements.

[0049] The correction unit further determines the propagation efficiency according to the type of emergency event. Different event types have different propagation speeds and impact ranges, which directly determine the dispatchable amount of the dispatch point. The time it takes for the event to propagate to the dispatch point can be calculated based on the distance and propagation speed, and the emergency resource penalty value is determined based on the ratio of this time to the rated time.

[0050] Of course, in some preferred embodiments, the emergency resource penalty value may also be optimized according to the propagation of events at adjacent scheduling points.

[0051] Based on the emergency resource penalty value, the correction unit corrects the types and quantities of resources predicted by the initialization unit. If the penalty value is high, it means that the scheduling urgency is high or the risk is high. The correction unit will increase the types and quantities of schedulable resources accordingly to ensure that the needs of emergency events can be met. On the contrary, if the penalty value is low, the correction unit may appropriately reduce the number of resources to avoid wasting resources.

[0052] This embodiment can more accurately calculate the dispatchable amount of each dispatch point and help balance the relationship between dispatch efficiency and dispatch value, thereby ensuring that emergency events can be responded to in a timely and effective manner and avoiding the problems of increased costs and decreased emergency response capabilities caused by excessive resource calls.

[0053] In an embodiment of the present invention, the strategy determination module includes: a scanning unit, which is used to adopt a circular scanning mode, perform a circumferential scan with the destination as the center, and use the scanned scheduling point with the shortest distance to the destination as the reference point to obtain a reference set; a filtering unit, which is used to remove the reference points whose adjacent reference points are less than the first distance threshold from the reference point set to obtain a reference point set; a combining unit, which is used to use a greedy algorithm to combine other scheduling points with any reference point in the reference point set to obtain a scheduling area; wherein the distance between the two farthest scheduling points in the scheduling area is less than the second distance threshold.

[0054] Among them, the greedy algorithm includes Prim's algorithm and Kruskal's algorithm, Dijkstra's algorithm, knapsack problem, Huffman coding problem, etc. The embodiment of the present invention adopts Dijkstra's algorithm, which solves the shortest path problem, that is, finding the shortest path from one specific vertex to another specific vertex in a directed or undirected weighted graph. The algorithm selects the vertex closest to the starting point in the current state at each step, and updates the shortest distances of other vertices.

[0055] By adopting the circular scanning mode, the dispatch point with the shortest distance to the destination can be quickly determined, which helps to reduce the response time in the dispatch process and improve the emergency response speed. The role of the filtering unit is to eliminate the dispatch points that are too close to the adjacent benchmark points, which can avoid excessive concentration or overlap of dispatch resources and ensure the reasonable allocation and utilization of resources. The combination unit uses a greedy algorithm to combine other dispatch points with the benchmark points to form a dispatch area. This ensures that the dispatch points in the dispatch area are reasonably distributed and the entire area is coherent and complete in dispatch.

[0056] In an embodiment of the present invention, the policy determination module also includes: a first value calculation unit, used to calculate a first matching degree between the types and quantities of dispatchable emergency resources and the highest-level emergency resource requirements, and determine a first value based on the matching degree; wherein the highest-level emergency resource requirements are determined based on the event type; a second value calculation unit, used to calculate a second matching degree between the types and quantities of dispatchable emergency resources, and determine a second value based on the second matching degree; and a third value calculation unit, used to calculate the value of emergency resources based on the first value and the second value.

[0057] Specifically, the main task of the first value calculation unit is to accurately calculate the degree of match between the types and quantities of dispatchable emergency resources and the highest level of emergency resource requirements. This degree of match is called the first degree of match, which can provide a clear basis for determining the first value of emergency resources. It is particularly worth mentioning that the determination of the highest level of emergency resource requirements is not arbitrary, but is closely related to the analysis of event types to ensure that resource scheduling can closely match actual emergency needs. The second value calculation unit focuses on evaluating the intrinsic match between the types and quantities of dispatchable emergency resources, which is called the second degree of match.

[0058] This embodiment deeply analyzes the correlation and complementarity between resource types and quantities, thereby providing a basis for judging the second value. This process not only helps us understand the actual situation of resources more comprehensively, but also provides strong data support for subsequent decision-making.

[0059] In an embodiment of the present invention, the comprehensive cost includes path cost and time cost. The path cost includes basic path cost and combined path cost. The time cost includes path time cost and loading time cost. Specifically, if the possible path is ABCDA (D), the basic path cost is the transportation cost from scheduling point A to scheduling point B in the scheduling area, the transportation cost from scheduling point B to scheduling point C, and the transportation cost from scheduling point C to destination D. The transportation cost of destination B returning to scheduling point A or scheduling point D is the basic path cost of the path after excluding any scheduling points multiplied by the emergency resource scheduling weight excluding the scheduling points.

[0060] This embodiment particularly considers the combined path cost, provides an evaluation index for combining with other possible paths after there are no dispatchable emergency resources at the dispatch point, and provides an evaluation index for changing the starting point of the possible dispatch path.
