DETAILED DESCRIPTION

[0016] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0017] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices. Example

[0018] This embodiment provides a natural resource survey task assignment method, which achieves workload balance by grouping each suspicious image spot and calculating the estimated task amount corresponding to each field task service party, ensuring that the task amount of each field task service party is basically equivalent, unifying the work progress, and ensuring the overall work progress. In addition, the natural resource survey task assignment method of this embodiment can realize automatic task allocation in the system, reduce the manual assignment workload of personnel, and improve efficiency.

[0019] See also Figure 1 As shown, the natural resource survey task assignment method of this embodiment includes but is not limited to the following steps: S101, obtaining information of multiple suspicious spots; Suspicious spots are geographical spots that currently require field evidence. The information obtained about suspicious spots includes but is not limited to the geographical location and resource type of the suspicious spots.

[0020] S102, determining a plurality of available field task service providers; The field task service provider is the party that actually performs the field investigation task, which can be an investigation and planning institute or other company with relevant professional capabilities. For example, multiple field task service providers can be entered into the system, and the field task service provider that performs field investigation on the batch of suspicious spots is selected from them, that is, the available field task service provider.

[0021] S103, dividing each suspicious image spot into multiple task packages according to the location range and basic task amount; Each task package includes at least one suspicious spot. In this step S103, a preliminary task division can be achieved for the suspicious spots. Among them, suspicious spots with similar distances are divided into the same task group, and the positions of the suspicious spots in the same task group will be made to be in the same area as much as possible, thereby reducing the scope of action of the field task service provider during the field investigation. In addition, for the preliminary divided task packages, the task volume in each task package can be preliminarily balanced according to the area and difficulty of the suspicious spots.

[0022] S104, allocating the nearest task package to each field task service provider; The location of the field task service provider can be set to its company address or other location, and can be input based on actual conditions in actual applications. In actual applications, the location of the field task service provider can be directly set to the location of the municipal district where it is located, without collecting specific location information. If multiple field task service providers are in the same municipal district, the closer task packages can be arbitrarily assigned to these field task service providers. In this embodiment, the nearest task package is assigned to each field task service provider, which can reduce the distance traveled by the field task service provider during the investigation process to reduce its working time.

[0023] S105, calculating the estimated task volume of each field task service provider to process its corresponding task package according to the information of the suspicious image spot and the location of the field task service provider; In step S105, based on the aforementioned preliminary assigned tasks, further task volume evaluation is performed on the field task service provider, so as to determine whether the tasks roughly assigned in the aforementioned step are reasonable.

[0024] S106, according to the estimated task volume, the suspicious image spots in the task package are deployed to balance the estimated task volume of each field task service provider when processing its corresponding task package; That is, for task packages with a higher estimated task volume, some of the suspicious spots will be allocated to other task packages to balance the task volume among different field task service providers.

[0025] S107, sending the final task package to the corresponding field task service provider; The system can automatically send relevant information or emails to the field mission service provider, or export the corresponding field mission resource package and distribute it manually.

[0026] The natural resource survey task dispatching method of this embodiment preliminarily divides the task packages, calculates the task volume based on the preliminarily divided task packages, and then allocates the suspicious map spots in the task packages based on the estimated task volume. This can quickly balance the task volume among different field task service parties and automatically complete the task dispatch, so that the overall work progress of different field task service parties is basically unified, thereby ensuring overall efficiency.

[0027] In some embodiments, Figure 2 , the steps of dividing each suspicious image spot into multiple task packages according to the location range and basic task volume include: S201, determining the number of field task service providers to be adopted; S202, according to the number of field task service providers, multiple suspicious spots are divided into a corresponding number of task packages, each task package includes at least one suspicious spot; the suspicious spots in each task package are adjacent in geographical location, and the task volume is balanced between the task packages according to the basic task volume; For example, when three field task service providers are used, the multiple suspicious spots that need to be investigated will be divided into three task packages. In this application, suspicious spots within the same range will be divided into one task package, and suspicious spots within the same range will not be divided into different task packages. Adjacent in this application means that the distance is within the set range, and there are no other suspicious spots between the two suspicious spots; there will not be a situation where two suspicious spots within the same range are divided into the same task package, and a suspicious spot between the two suspicious spots is divided into another task package. Ensure that the suspicious spots in each task package are concentrated in one area.

[0028] In some embodiments, the basic task volume is determined according to the area of ​​the suspicious spot and the difficulty of the investigation of the suspicious spot itself. Exemplarily, the basic task volume can be represented by the investigation time, and the investigation time is matched according to the area of ​​the suspicious spot. Different area ranges can correspond to different investigation times. It is understandable that the larger the area, the longer the investigation time. For example, the investigation time of suspicious spots with an area of ​​less than 500 square meters is set to 1 hour; the investigation time of suspicious spots with an area of ​​500 square meters to 1000 square meters is 2 hours. In practical applications, the investigation time required for suspicious spots of different areas can be set according to experience. In addition, the factors that affect the difficulty of the investigation of the suspicious spots themselves include but are not limited to the complexity of the shape of the spots and the geographical type of the spots. The final investigation difficulty can be obtained by adding the influence coefficient of each factor to the basic investigation difficulty. The investigation difficulty can be used as a coefficient and multiplied by the aforementioned determined investigation time, and the obtained time is used as the basic task volume. In practical applications, the shape of suspicious spots can be roughly identified. For suspicious spots that are similar to simple regular shapes (such as quadrilaterals, triangles, etc.), their impact coefficient on the difficulty of investigation can be configured to 0; for irregular shapes, the impact coefficient of these shapes on the difficulty of investigation can be configured between 0.1 and 0.5. The impact coefficients of various geographical types on the difficulty of investigation can also be pre-configured in the system. After adding the impact coefficients of each influencing factor, plus the basic difficulty coefficient of 1, the final investigation difficulty is obtained.

[0029] Through the above steps, a simple estimate can be made of the workload of suspicious spots during the investigation process, so that the workload of each task package is relatively balanced. However, in actual field investigation work, the work of field investigators does not start from the time they arrive at the location of the suspicious spots to provide evidence. In fact, it takes a lot of time and energy for field investigators to rush to the location of the suspicious spots. Therefore, this embodiment also calculates the estimated workload of each field task service provider to handle its corresponding task package through the information of the suspicious spots and the location of the field task service provider, which can reflect the working time required by the field task service provider during the entire field investigation process, and balance the workload based on the actual time that may be consumed, which can more accurately ensure that the work progress of different field task service providers is basically unified, and ensure the work efficiency of the overall investigation process.

[0030] In some embodiments, Figure 3 The step of calculating the estimated task volume of each field task service provider to process its corresponding task package according to the information of the suspicious image spot and the location of the field task service provider includes: S301, planning a path for the field survey based on the location of the field mission service provider and the location of each suspicious image spot in the corresponding mission package; As an example, assume that the field task service provider A1 is closest to the range of task package B1. Then task package B1 will be initially determined to be assigned to the field task service provider A1. If task package B1 includes multiple suspicious spots, the traversal path from the location of the field task service provider to all suspicious spots in task package B1 is planned, that is, to ensure that the path can cover all suspicious spots and the distance is the shortest. Of course, during the planning process, it is executed according to the set working hours of the day. If the time required to traverse all suspicious spots in task package B1 exceeds the set working hours of the day, it needs to be planned as a multi-day trip.

[0031] In practical applications, path planning can be performed using various existing path planning algorithms or deep learning models. This application does not limit the specific path planning method, and only performs subsequent deployment based on the results obtained by path planning.

[0032] S302, calculating the estimated task volume of the task package for the field task service provider according to the path planned by the path planning; After completing the path planning, based on the path conditions, the time required for the field task service provider to reach all the suspicious spots in the task package for which it is responsible can be calculated. Adding the time required to investigate each suspicious spot, an estimated total working time can be obtained, which is the estimated task volume.

[0033] In some embodiments, Figure 4, according to the path planned by the path planning, the steps of calculating the estimated task volume of the task package for the field task service provider include: S401, obtaining road information along the planned route, and identifying vehicle-passable paths and non-vehicle-passable paths; Among them, the vehicle-accessible path refers to the road that allows vehicles to pass. Based on the data in the geographic system, the location and information of various lanes can be determined. The non-vehicle-accessible path is the part that vehicles cannot pass. If there is no relevant information about the lane at the corresponding location in the geographic system, it can be considered as a non-vehicle-accessible path.

[0034] S402, determining a basic travel time according to the length of the vehicle travel path; In actual applications, data from relevant navigation software can be accessed or relevant services can be used to accurately determine the time required for the vehicle to travel along the route, which is also the basic travel time.

[0035] S403, determining the additional travel time according to the length and difficulty of each non-vehicle travel path; S404, obtaining an estimated task volume according to the basic travel time, the additional travel time and the basic task volume; Add up the time spent on each route and the time spent in the investigation process to get the estimated total time, which is the estimated task volume. It can be understood that in this application, time is used as the statistical unit for estimating the task volume; in actual applications, workload evaluation methods other than time can also be introduced as a representation of the estimated task volume.

[0036] In some embodiments, Figure 5 , the additional travel time is determined based on the length and difficulty of each non-vehicle path, including: S501, identifying the difficulty coefficient and path length of the non-vehicle path according to the road information along the way; For example, the travel time can be obtained by dividing the path length by the set travel speed. For routes that are difficult to pass, the travel time is multiplied by the corresponding difficulty influence coefficient to obtain the additional travel time. The road information along the way may include information such as the geographical type, environment, and height difference of the location or surrounding of the non-vehicle pass path. It is understandable that the more complex the environment around the non-vehicle pass path reflected by the road information along the way, the greater the height difference, and the higher the pass difficulty coefficient.

[0037] S502, determining the additional travel time according to the length and difficulty coefficient of the non-vehicle travel path; Exemplarily, the reference travel time may be obtained by dividing the length by a preset travel speed, and then multiplied by the difficulty coefficient to obtain the above-mentioned additional travel time.

[0038] In some embodiments, Figure 6 The step of identifying the difficulty coefficient of the non-vehicle passage path according to the road information along the way includes: S601, determining a first difficulty coefficient for an identifiable non-vehicle passage according to road conditions; In this embodiment, the identifiable non-vehicle paths refer to paths with obvious road features, such as sidewalks, country roads, etc. The pre-set model can be used to identify the planned path and its surroundings to determine whether there are paths with obvious road features. For non-vehicle paths with good road conditions, a lower first difficulty coefficient will be set; and for non-vehicle paths with poor road conditions, a higher first difficulty coefficient can be set.

[0039] S602: For a path that cannot be directly identified as a road, a second difficulty coefficient is determined according to the geographical type, and the second difficulty coefficient is not less than the first difficulty coefficient; Paths that cannot be directly identified as roads mean that some paths do not have obvious road features, and are neither roads that vehicles can pass through nor roads that are obvious for people to walk on; for example, they require climbing mountains or crossing forests.

[0040] This embodiment can perform simple classification based on road conditions and determine the difficulty of travel based on whether there are obvious road features on the path.

[0041] The value range of the second difficulty coefficient is not less than the first difficulty coefficient, that is, at least equal to the maximum value of the first difficulty coefficient. For example, if the path that cannot be directly identified as a road is of grass type, its second difficulty coefficient can be the same as the maximum value of the first difficulty coefficient; if the path that cannot be directly identified as a road needs to pass through woodland or mountains, the determined second difficulty coefficient will be higher than the maximum value of the first difficulty coefficient.

[0042] In some embodiments, Figure 7 The step of identifying the path length of the non-vehicle passing path according to the road information along the way includes: S701, calculating the length of the identifiable non-vehicle path according to the actual road path; S702: For a path that cannot be directly identified as a road, determine the length of the path according to the straight-line distance between the starting and ending points; The starting point can be the end of the previous road path, and the end point can be the location of the next identifiable road or the location of the suspicious patch at the end point. Connecting the starting and ending points as a path for calculation simplifies the calculation process.

[0043] In this embodiment, the step of allocating suspicious spots in the task package according to the estimated task volume includes: allocating suspicious spots in the task package between geographically adjacent task packages according to the estimated task volume, and recalculating the estimated task volume when each field task service provider processes its corresponding task package until the task volume balance requirement is reached. Adjacent task packages refer to two task packages whose distance is within a set range and there is no other task package between them.

[0044] Adjacent task packages refer to the task packages that are closest in all directions. For example, the suspicious image spots closest to another task package can be preferentially deployed to another task package to minimize the increase in workload caused by task deployment to another field task service provider.

[0045] As a specific example, Figure 8 As shown, the square graphic represents the suspicious spot 1, the circle represents the location of the field task service provider, and the dotted line represents the division of the task package. Assume that the estimated task volume of task package B1 processed by field task service provider A1 is C1; the estimated task volume of task package B2 processed by field task service provider A2 is C2; the estimated task volume of task package B3 processed by field task service provider A3 is C3; and the estimated task volume of task package B4 processed by field task service provider A4 is C4. Task package B1, task package B2, task package B3 and task package B4 each include at least one suspicious spot 1. To simplify the example, it is assumed in the example that each task package includes three suspicious spots 1, and their specific shapes are ignored. Among them, task package B3 is adjacent to task package B1, task package B2 and task package B4; task package B2 is adjacent to task package B1 and task package B3, and is separated from task package B4 by task package B3, so the two are not adjacent.

[0046] Assuming that the estimated task volume C1 is significantly higher than the other estimated task volumes C2, C3, and C4, at least one suspicious spot 1 in task package B1 can be deployed to at least one of its adjacent task packages B2, B3, and B4. Among them, the suspicious spot 1 in task package B1 close to task package B2 is preferentially deployed to task package B2, and / or, the suspicious spot 1 in task package B1 close to task package B3 is preferentially deployed to task package B3, and / or, the suspicious spot 1 in task package B1 close to task package B4 is preferentially deployed to task package B4.

[0047] like Fig. 9 As shown, assuming that the above example deploys a suspicious spot 1 in task package B1 that is closest to task package B2 to its adjacent task package B2, a suspicious spot 1 will be added to the new task package B2. In actual applications, more than one suspicious spot 1 can be deployed each time, and multiple deployment attempts can be made to seek a better task assignment solution.

[0048] Of course, before deployment, the path planning is re-performed and the corresponding estimated task volume is calculated to determine whether deployment is still needed. If the difference between the estimated task volumes is within an acceptable range, or the difference between the estimated task volumes cannot be further reduced, it can be considered that the task volume balance requirement has been achieved. At this time, the suspicious spots contained in each task package are the final results, and the investigation tasks will be issued to the field task service provider based on the allocation situation at this time.

[0049] This embodiment also provides a natural resource survey task assignment system 100, see Fig.10 As shown, including: The information acquisition module 101 is used to acquire information of multiple suspicious spots.

[0050] The service provider screening module 102 is used to determine a plurality of available field task service providers.

[0051] The task pre-assignment module 103 is used to divide each suspicious map spot into multiple task packages according to the location range and the basic task volume; assign the nearest field task service provider to each task package; and calculate the estimated task volume of each field task service provider to process its corresponding task package based on the information of the suspicious map spot and the location of the field task service provider.

[0052] The task allocation module 104 is used to allocate suspicious image spots in the task package according to the estimated task volume, so as to balance the estimated task volume of each field task service provider when processing its corresponding task package.

[0053] The task sending module 105 is used to send the final task package to the corresponding field task service provider.
