[0050] The following uses specific specific examples to illustrate the embodiments of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that, without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0051] Please refer to Figure 1 , Figure 1 is a flowchart of a target management method according to an embodiment of the present invention. Specifically, as shown in Figure 1 , the target management method at least includes steps S110 - step S140:

[0052] Step S110, establish a three-dimensional virtual model of the management area based on digital twins and a target model of the management objectives in the management area, and associate the three-dimensional virtual model with the target model;

[0053] Build a 1:1 three-dimensional virtual model of the management area in the Unreal Engine (UE). The three-dimensional virtual model includes management targets (the management targets are targets with changing positions within the management area), materials, and containers. Collect on-site equipment parameters through the Internet of Things system, build and configure a Kafka cluster, and set corresponding topics for the transmission of on-site data. At the same time, by adding physical properties and constraint conditions in UE, use on-site data to simulate and restore the movement and interaction behaviors of on-site equipment in the real world, and achieve 3D (Three Dimensions) visual real-time display of the on-site production process and production information. Kafka is an open-source stream processing platform developed by the Apache Software Foundation and is written in Scala and Java. Kafka is a high-throughput distributed publish-subscribe messaging system that can handle all action stream data of consumers on websites.

[0054] Through an interface request, obtain the information of the management target in real time from the target management system (a system used to manage the management target, and the target management system includes information about the management target, and the information about the management target can specifically include the number, position coordinates, movement direction, status, fault duration, and task information of the management target, etc.) at a fixed frequency. Use on-site data to simulate and restore the movement and interaction behaviors of the management target in the real management area, and achieve 3D visual real-time display of the production process and production information of the management target, so as to obtain the correlation relationship between the virtual model and the target model.

[0055] In one embodiment, the management target is set in the management area, the management area is the final assembly workshop, and the management target can be an AGV (Automated Guided Vehicle) in the management area. When the management target is an AGV, the information of the management target can also include: trolley battery power, battery temperature.

[0056] Step S120, obtain the floor plan of the management area based on the three-dimensional virtual model;

[0057] For the three-dimensional virtual model of the management area, select the top-down direction of UE to take a screenshot of the entire management area to obtain the floor plan of the management area.

[0058] Step S130, obtain the position data of the management target, and obtain the distribution density of the management target based on the position data of the management target;

[0059] Please refer to Figure 2 , Figure 2 which is the flowchart of the distribution density calculation method according to an embodiment of the present invention. In Figure 2Among them, obtaining the distribution density of management objects based on the location data of management objects includes:

[0060] Step S210, obtaining the location coordinates of each management object;

[0061] Step S220, calculating the first distance between each management object and other management objects;

[0062] Step S230, comparing the first distance with a first preset distance to determine the number of management objects whose first distance is less than the first preset distance, so as to obtain the distribution density of management objects.

[0063] As an example, first, the database of the target management system is scanned regularly, and the location coordinates (x, y, z) of each obtained management object are stored as a vector in a newly created three-dimensional vector structure array, which is used as the input of the distribution density function. In the function, a for loop is used to traverse this three-dimensional vector structure array. The number of loops is the length of the array, the loop variable is of integer type and is given an initial value of 0. In each loop, the first distance between the i-th vector and each of the remaining vectors in the three-dimensional vector structure array is calculated using the distance function distance. When the first distance is less than the first preset distance, the variable NumOfLocationInRange representing the distribution density (with an initial value of 0) is incremented by 1. In this way, the distribution density NumOfLocationInRange of the i-th management object within the preset distance range is calculated. The x, y coordinate values and the distribution density of the i-th management object are combined into a new three-dimensional vector structure array (x, y, NumOfLocationInRange). Therefore, after the loop is completed, a new three-dimensional vector structure array is returned. If there are m management objects in total, the distances between the first management object and the remaining 2nd, 3rd,..., m - 1, m-th management objects are calculated and recorded as the first distance. Then, a total of m - 1 first distances can be obtained. The sizes of the m - 1 first distances are respectively compared with the first preset distance, and the number of trolleys whose first distance is less than the first preset distance is determined and recorded as the distribution density of the management object. For example, with the first management object as the center, within the first preset distance from the center, there are n trolleys with a distance less than the first preset distance, then the distribution density of the first management object is n, where n and m are integers greater than 0.

[0064] Step S140, mapping the distribution density onto a planar graph according to the location data of management objects to generate a heat map of management objects;

[0065] The received location data of management objects, that is, the spatial coordinate information, is mapped to a specific point on the planar graph, and all points on the planar graph are plotted according to the distribution density of management objects, thereby generating a heat map of management objects.

[0066] As an example, the heat map is developed using the control blueprint UMG (Unreal Motion Graphics, a powerful user interface creation tool for creating various user interface elements) of the UE. The component canvas panel Canvas Panel of it is used as the root component and the canvas size is set here. The floor plan is placed at the bottom layer as the background. On the floor plan, the Render Targe of the rendering module is used to draw the points of the management targets. Each time when drawing, it is necessary to call the distribution density function to calculate the number of all management targets within a fixed distance range of each management target, that is, the distribution density of the management target, and map the received spatial coordinate information to a specific point on the floor plan through the numerical mapping function map range clamped, so as to generate the execution map.

[0067] In one embodiment, the target management method further includes: determining the level of the distribution density according to the size of the distribution density; generating the distribution density of each management target on the floor plan according to the level of the distribution density.

[0068] As an example, when generating the distribution density, by calling different material balls, the distribution density of each management target is drawn on the floor plan according to the level of the distribution density.

[0069] Specifically, when generating the distribution density, the level of the distribution density is determined according to the size of the distribution density. The larger the distribution density, the higher the level of the distribution density, or the level of the distribution density is directly represented by the distribution density. When drawing the distribution density, different colors are used to represent it within different ranges according to different levels of the distribution density (generally, the highest level of the distribution density uses red, and then orange, yellow, etc. can be used in turn). When generating the distribution density, the spatial coordinate information of the management target is mapped to a specific point on the floor plan through the numerical mapping function map range clamped, and the material ball is drawn at the corresponding point using the Draw Material function of the drawing material. The color of the material ball is determined by the level of the distribution density. In this way, finally, all the points on the floor plan are drawn by calling different materials according to the level of the distribution density of the management target.

[0070] In one embodiment, when generating the distribution density of each management target, it is generated in ascending order according to the level of the distribution density.

[0071] After obtaining a new array of three-dimensional vector structures (each array element contains information about the x and y coordinate values and the distribution density of each management target, which is composed of (x, y, NumOfLocationInRange)), the sort function is used on this array and sorted in ascending order according to the distribution density. Finally, an array of three-dimensional vector structures sorted in ascending order according to the distribution density is returned (each array element contains information about the x and y coordinate values and the distribution density of each management target, which is composed of (x, y, NumOfLocationInRange)).

[0072] Step S150, manage the management target based on the heat map.

[0073] In one embodiment, the target management method includes:

[0074] Receive a first trigger operation to display the heat map of the management target through the first trigger operation; receive a second trigger operation to display the traffic of the management target through the second trigger operation; receive a third trigger operation, obtain the three-dimensional spatial information of the touch point corresponding to the third trigger operation, and feedback the three-dimensional spatial information to the three-dimensional virtual general assembly workshop model.

[0075] In the digital twin system, construct a heat map interface button and a data display button. Clicking the heat map interface button can open the heat map interface, that is, perform a first trigger operation on the display module, and then display the heat map interface; clicking the data display button, that is, perform a second trigger operation on the display module, and then display the traffic of the management target.

[0076] On the heat map interface, double-click a specific point on the heat map, that is, perform a third trigger operation on the display module. Map the point on the heat map according to the proportional relationship and feedback it to the three-dimensional virtual workshop model, and the digital twin workshop will switch to the corresponding position.

[0077] Please refer to Figure 3 , Figure 3 which is the flowchart of the calculation method for the traffic of the management target in an embodiment of the present invention. The calculation method for the traffic of the management target includes:

[0078] Step S310, determine the key points in the three-dimensional virtual model of the management area;

[0079] Step S320, determine the second distance between the management target and the key points according to the position data of the management target;

[0080] Step S330, compare the second distance with a second preset distance to determine the number of trolleys whose second distance is less than the second preset distance, and obtain the traffic of the management target corresponding to the key points.

[0081] As an example, key points (hot spots or intersections) are set in the three-dimensional virtual model of the management area. After receiving the position data of the management targets each time, the position data of all management targets and the position data of the key points are traversed, and the position data of the key points is compared with the position data of the management targets, so as to count the number of management targets passing through the key points per unit time.

[0082] By setting key points in the three-dimensional virtual model of the management area, the coordinate positions of the key points are obtained; the coordinate positions of each management target can be obtained through the target management system, and then the distance between the key points and each management target is calculated, which is recorded as the second distance. Compare the size of the second distance with the second preset distance, determine the management targets whose second distance is less than the second preset distance, so as to determine the corresponding number of management targets, and finally the traffic flow of the management targets per unit time can be obtained.

[0083] At the same time, the key points can be marked on the heat map, and the traffic flow of the management targets at the key points is mapped to the heat map to display the traffic flow in the data display area of the heat map interface.

[0084] In one embodiment, the target management method further includes: judging the congestion situation of the management targets based on the distribution density and traffic flow of the management targets; if the distribution density of the management targets is greater than the first preset threshold or the traffic flow is greater than the second preset threshold, it is determined that the management targets are congested.

[0085] Compare the distribution density of the management targets with the first preset threshold. When the distribution density of the management targets is greater than the first preset threshold, it is considered that congestion has occurred; at the same time, compare the traffic flow of the management targets with the second preset threshold. When the traffic flow of the management targets is greater than the second preset threshold, it is considered that congestion has occurred. It should be noted that the distribution density can be used to determine whether the passage of the car is congested, and this position is uncertain; while the traffic flow of the management targets is generally used to determine whether congestion occurs at the key points of the car, such as whether congestion occurs at the designated intersection.

[0086] Of course, in addition to using the distribution density and traffic flow to judge whether congestion occurs separately, the two can also be combined to judge congestion. For example, when the distribution density is greater than the first preset threshold and the traffic flow of the management targets is greater than the second preset threshold, it is considered that congestion has occurred.

[0087] It should be understood that the magnitudes of the sequence numbers of the steps in the above embodiments do not mean the order of execution. The execution order of each process should be determined according to its function and internal logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.

[0088] Through the heat map interface of the present invention, the distribution of all management objectives can be known at a glance, and the hot spots in the current operation process of the management objectives can be intuitively and quickly identified according to the heat map color; combined with the key point flow value, accurate prediction of whether congestion occurs can be carried out. Double-clicking on any point in the heat map interface can switch the management area to this point. When a problem point or a hot spot is found in the heat map, this method can be used to quickly view the detailed operation process of this point in the management area. Therefore, the combined application of the heat map and the three-dimensional virtual management area can improve the management efficiency. By creating a three-dimensional virtual model of the management area and a target model of the management objectives, the operation status of the management objectives in the management area can be reflected in real time. Managers can monitor the operation of the management objectives throughout the process at any time and place, including the operation status and fault information of the management objectives, so as to achieve efficient management of the management objectives. When simulating and verifying the operation plan of the management objectives or improving the production beat, through the heat Figure 1 map, bottleneck points and specific flow data can be quickly found, avoiding discovering problems only when on-site operations are carried out or not fully solving problems due to insufficient observation, and reducing the on-site commissioning cycle and cost.
