Description

Technical Field

[0001] Embodiments of the present invention relate to the field of information technology, and more specifically, embodiments of the present invention relate to a method, system, medium and computing device for acquiring a cargo container storage location. Background Art

[0002] This section is intended to provide a background or context to embodiments of the invention that are recited in the claims. No description herein is admitted to be prior art by inclusion in this section.

[0003] With the development of the transportation industry, the cargo container throughput of various transportation hubs has increased dramatically, resulting in urgent problems such as hazardous cargo container yard management, hazardous cargo container placement, and hazardous cargo isolation. Among them, hazardous cargo container yard management is mainly to determine the storage location for hazardous cargo containers that are about to enter the yard, which is one of the important issues in cargo container management.

[0004] At present, the yard management plan for cargo containers is mostly to manually arrange the storage locations of various types of goods based on operating procedures and formulate corresponding cargo storage plans. Due to the large number of isolation rules for dangerous goods and the uncertainty of the time of goods entering the yard, for example, a large number of goods may need to be stored in the yard in the same time period, so the technical requirements for yard management personnel are high, and the workload of yard management personnel may be too heavy, which easily makes the manually formulated cargo storage plan have a high risk factor and low formulation efficiency. Once omissions or negligence occur in the cargo storage plan, the consequences are often irreversible, such as port explosions. In addition, it is difficult to optimize the utilization of storage space for manually formulated cargo storage plans, resulting in waste of yard space, which in turn affects the efficiency of cargo container entry.

[0005] In summary, the current container storage scheme has the problems of high technical requirements for yard management personnel, high risk coefficient of manually formulated cargo storage plan, low formulation efficiency, and easy waste of yard space. Therefore, it is urgent to design an improved container storage scheme to solve the above problems of the current container storage scheme. Summary of the invention

[0050] In this article, it is important to understand that the concepts involved have the following meanings:

[0053] Group: Multiple containers of the same category and adjacent locations in each container area are considered a group.

[0054] In addition, any number of elements in the drawings is for illustration and not limitation, and any naming is only for distinction and does not have any limiting meaning.

[0055] The principle and spirit of the present invention are explained in detail below with reference to several representative embodiments of the present invention. SUMMARY OF THE INVENTION

[0057] The inventors have discovered that current container storage plans have high technical requirements for yard management personnel, and manually formulated container storage plans have high risk factors, low formulation efficiency, and waste of yard space.

[0058] In order to overcome the existing technical problems, the present invention proposes a method, device, system, medium and computing device for obtaining the storage position of cargo boxes. The method includes: obtaining the attribute information of the cargo boxes to be admitted; simulating the admission based on the attribute information of the cargo boxes to be admitted to obtain the simulated admission result, wherein the simulated admission result includes the simulated storage position of the cargo boxes to be admitted and the storage position evaluation result, and the storage position evaluation result is obtained by the cargo box risk degree and / or the yard space utilization rate; if the storage position evaluation result does not meet the preset conditions, it triggers the merging and storage of multiple cargo boxes in the yard and re-obtains the simulated admission result; if the storage position evaluation result meets the preset conditions, the simulated storage position is used as the entry storage position of the cargo boxes to be admitted.

It can be understood that the principles and methods of the device, system, medium and computing equipment are similar and will not be repeated here.

[0060] After introducing the basic principles of the present invention, various non-limiting embodiments of the present invention are described in detail below.

[0061] Application Scenario Overview

[0062] The embodiments of the present invention can be applied to cargo box position adjustment scenarios, especially dangerous goods container (i.e., hazardous goods container) warehousing scenarios. For example, cargo box position adjustment scenarios can be port cargo box storage scenarios, or procurement cargo box warehousing scenarios of large factories or large enterprises, or cargo entry scenarios of logistics hubs, or other cargo box position adjustment scenarios. The embodiments of the present invention do not limit the cargo box type, nor the number or category of items in the cargo box.

[0063] Exemplary Methods

[0064] The following describes a method for container storage according to an exemplary embodiment of the present invention in combination with application scenarios and with reference to the accompanying drawings. It should be noted that the above application scenarios are only shown to facilitate understanding of the spirit and principle of the present invention, and the embodiments of the present invention are not limited in this regard. On the contrary, the embodiments of the present invention can be applied to any applicable scenario.

[0065] Figure 1A is a flow chart of an embodiment of a method for obtaining a cargo box storage position according to the first aspect of an implementation manner of the present invention, Figure 1B It is a flow chart of an embodiment of another method for obtaining the storage position of a cargo box according to the first aspect of an embodiment of the present invention. Although the present invention provides method operation steps or device structures as shown in the following embodiments or drawings, more or fewer operation steps or module units may be included in the method or device based on routine or no creative labor. In the steps or structures where there is no necessary causal relationship logically, the execution order of these steps or the module structure of the device is not limited to the execution order or module structure shown in the embodiments or drawings of the present invention. When the method or module structure is applied in an actual device, server or terminal product, it can be executed sequentially or in parallel according to the method or module structure shown in the embodiments or drawings (for example, a parallel processor or multi-threaded processing environment, or even a distributed processing, server cluster implementation environment).

[0066] A specific implementation example is Figure 1B As shown, in one embodiment of a method for obtaining a cargo box storage position provided by the present invention, the method may include:

[0067] S101, obtaining attribute information of the cargo box to be admitted;

[0068] In this embodiment, before S101, S1001 is executed to load the yard storage status data, and then S101 is executed again to obtain the attribute information of the container to be admitted from the yard storage status data. A possible implementation method is to load the system configuration data and the yard storage status data before S101. The attribute information of the container to be admitted includes but is not limited to one or a combination of the yard map information, the container information in the yard, the container information to be admitted, and the container risk parameters. The above information is explained in detail below with examples:

[0069] The yard map information is used to store the positional relationship between each container position (such as the neighborhood relationship) so as to calculate the target function of the container later. A possible implementation method is, for example, Figure 2The yard map shown includes the location information of the container slots and the information of the cargo containers stored in the container slots, such as the cargo container types and the number of cargo container layers in the container slots. Figure 2 The stacking yard map shown is composed of several rows and several columns. The cells marked with numbers represent the locations where containers can be stacked, and the numbers in the cells represent the container area types. Further, the container area types can be the container area type table shown in Table 1.

[0070] Table 1 Box area type table

[0071]

[0072] The cargo container information in the yard, that is, the cargo container information already in stock in the yard, can be used to store multiple information of the cargo containers that have entered the yard, including but not limited to the cargo container identification that has entered the yard, the cargo container category that has entered the yard, the batch number to which the cargo container belongs, the designated container area, the cargo container status information, and the cargo container location information, such as the cargo container information table already in stock in the yard shown in Table 2.

[0073] Table 2 Information on containers stored in the yard

[0074]

[0075] The batch cargo box information to be entered may be, for example, the cargo box information table to be entered as shown in Table 3. The batch cargo box information to be entered includes but is not limited to an operation identification (ID), a batch number, a category, a quantity, a cargo description, and a designated container area.

[0076] Table 3 Information of cargo boxes waiting to enter the site

[0077]

[0078] Similarly, the sequence information of cargo boxes to be admitted is generated from the batch information of cargo boxes to be admitted; the sequence information of cargo boxes to be admitted includes but is not limited to the identification of the cargo boxes that have been admitted, the category of the cargo boxes that have been admitted, the batch number to which the cargo boxes belong, the designated container area, the cargo box status information, the cargo box location information, and the cargo box safety risk value, such as the sequence list of cargo boxes to be admitted shown in Table 4.

[0079] Table 4: List of cargo boxes to be admitted

[0080]

[0081] The container risk parameters include but are not limited to the minimum spacing risk parameter table, the maximum spacing risk parameter table, the spacing impact risk parameter table, and the layer height risk parameter table. The actual data in the above tables can be pre-entered based on experience. The risk parameter table is used to calculate the objective function of each container. For example, the layer height risk parameter table shown in Table 5, the minimum spacing risk parameter table shown in Table 6, the maximum spacing risk parameter table shown in Table 7, and the spacing impact risk parameter table shown in Table 8.

[0082] Table 5 Layer height risk parameter table (H)

[0083]

[0089]

[0090] Table 8 Interval impact risk parameters

[0091] (The risk is reduced after the 8th and 9th category cargo boxes are separated)

[0092]

[0093] After loading the system configuration data and the yard storage status data, a specific implementation step of S101 includes: obtaining the attribute information of the container to be entered, generating the container area status information based on the container information in the yard and the attribute information of the container to be entered, so as to realize the location search based on the container area status information when the container to be entered is simulated to enter the yard.

[0094] After the attribute information of the cargo box to be admitted is obtained, S102 is executed to perform a simulated admission based on the attribute information of the cargo box to be admitted to obtain a simulated admission result.

[0095] In a specific implementation of this step, based on the category information of the cargo box to be admitted and the pre-loaded box area information, the idle neighboring positions adjacent to the cargo boxes of the same category as the cargo box to be admitted are obtained; the idle neighboring positions are used as simulated storage positions to simulate and obtain the storage position evaluation results corresponding to the idle neighboring positions.

[0096] In this embodiment, the simulated entry results include but are not limited to the simulated storage location and storage location evaluation results of the cargo boxes to be entered, and the storage location evaluation results are obtained by the cargo box risk and / or the yard space utilization rate. Specifically, based on the cargo box risk and the yard space utilization rate, an objective function is set to calculate the storage location of each cargo box to be entered, such as the box area, box position (row, column, layer), that is, the objective function is F(p) = a1F1(p)+a2F2(p);

[0097] Among them, a1 and a2 are weights. If space utilization does not need to be considered, a1 can be set to 0 and a2 can be set to 1. F1(p) is the utilization rate of the yard space, that is, the proportion of space utilization allocated to the yard for cargo containers waiting to enter, which is used to evaluate the ability of the port management system to optimize storage space; for example , where n is the number of containers in the neighborhood of position p. Further, the risk function of position p and container C that has entered the site is defined as: ; where x is the map distance from p to C, is the highest risk distance for categories p and C, is the minimum risk distance between p and C, and c is the layer height risk parameter of p, which are obtained from Tables 5, 7, and 8 above. F2(p) is the risk of the container, which is the sum of the distance between multiple containers to be admitted and the risk of different types of dangerous goods. For example, the risk assessment function is , where C is the stored boxes, p is the candidate entry position, and N is the number of stored boxes.

[0098] The constraint condition of the objective function is that different types of dangerous goods must meet different minimum spacing requirements. For example, the dangerous goods category is the classification data table of cargo boxes to be admitted as shown in Table 9, and the minimum spacing requirement is the dangerous goods isolation table shown in Table 10. When the constraint conditions are met, the objective functions corresponding to different container positions are calculated by searching for free positions in the yard to select the storage position of the cargo boxes to be admitted with the smallest objective function.

[0099]

[0100] Table 10 Dangerous Goods Segregation Table

[0101]

[0102] The minimum spacing requirements vary according to different scenarios. For example, when Table 10 shows the isolation of dangerous goods in a warehouse, "1" means that the corresponding goods need to be separated by a preset distance, such as 3 meters, "2" means that the corresponding goods need to be stored in separate warehouses, "3" means that the corresponding goods need to be separated by a warehouse, and "4" means that the corresponding goods need to be separated by a preset number of warehouses. For another example, when Table 10 shows the isolation of dangerous goods in a site, "1" means that the corresponding goods need to be separated by 3 meters, "2" means that the corresponding goods need to be separated by 10 meters, "3" means that the corresponding goods need to be separated by 30 meters, and "4" means that the corresponding goods need to be separated by 30 meters. "×" means no spacing requirement.

[0103] After S102, execute S1002 to determine whether the storage location evaluation result meets the preset conditions. In this embodiment, the preset conditions are not limited to multiple. Different preset conditions can be set according to different storage scenarios of cargo boxes to be entered to confirm that the simulated storage location meets the risk storage requirements. In one possible implementation, the preset condition is that the storage location evaluation result corresponding to the idle neighborhood position is less than the set evaluation threshold.

[0104] If the stacking location evaluation result does not meet the preset conditions, it means that the simulated stacking location does not meet the safety storage requirements. In this case, S103 is executed. If the stacking location evaluation result does not meet the preset conditions, it triggers the merging of multiple cargo boxes in the yard and re-obtaining the simulated entry result. Specifically, S103 can be divided into the following sub-steps:

[0105] S1003, adjust the storage positions of multiple in-yard cargo boxes to merge and store the multiple in-yard cargo boxes, and execute S1004, simulate entry based on the storage status information of the multiple in-yard cargo boxes after the merged storage and the attribute information of the cargo boxes to be entered, so as to obtain the simulated entry result again. Among them, multiple cargo boxes of the same category and adjacent positions are divided into a group, and the yard area storing at least one group is divided into a box area. Optionally, the merged storage includes group merging and / or box area merging; specifically, group merging is to merge and store multiple groups of the same category, and box area merging is to merge groups of different box areas and store them in one of the multiple box areas.

[0106] Specifically, in S1003, a specific implementation method of adjusting the storage positions of multiple cargo boxes in the field to merge and store the multiple cargo boxes in the field is: based on the storage status information of multiple groups of the same category in a box area, determine whether the movement cost evaluation information after the multiple groups are merged is lower than the first displacement cost threshold. If the movement cost evaluation information after the multiple groups are merged is lower than the first displacement cost threshold, it means that the cost paid by the movement method during the merging of multiple groups is within an acceptable range, that is, in this case, triggering the group merger to move multiple groups of the same category in the box area to adjacent positions, which helps to reduce the box area. If the movement cost evaluation information after the multiple groups are merged is not lower than the first displacement cost threshold, it means that the cost paid by the movement method during the merging of multiple groups is not within an acceptable range, that is, in this case, based on the storage status information of multiple groups of the same category in multiple box areas. Further, determine whether the movement cost evaluation information after the multiple groups in the multiple box areas are merged is lower than the second displacement cost threshold. If the movement cost evaluation information after the multiple groups in the multiple bins are merged is lower than the second displacement cost threshold, it means that the cost of the movement method in the process of merging the multiple groups in the multiple bins is within an acceptable range, that is, in this case, the bin merger is triggered to move the multiple groups of the same category in the multiple bins to one of the multiple bins. It should be noted that the first displacement cost threshold and the second displacement cost threshold can be set to the same value or different values.

[0107] After S102, or after multiple containers in the yard are combined and stacked in S1004 and the simulated entry result is obtained again, it is determined whether the stacking position evaluation result meets the preset conditions; if the stacking position evaluation result meets the preset conditions, S104 is executed, and specifically the simulated stacking position is used as the entry stacking position of the containers to be entered, thereby realizing dynamic control of the entry stacking position of the containers.

[0108] The preset condition is that the evaluation result of the storage location corresponding to the idle neighboring location is less than the set evaluation threshold. A specific implementation of this step is to use the idle neighboring location as the entry storage location for the container to be entered, where the evaluation result of the storage location corresponding to the idle neighboring location is the weighted sum of the container risk and the yard space utilization rate. In a possible implementation, the evaluation threshold fm is set to an acceptable objective function value, such as 0.5.

[0109] In a possible implementation of this step, if the evaluation result of the storage position corresponding to the idle neighborhood position is not less than the set evaluation threshold, then the idle position in the preset container area is obtained, and the idle position is used as the simulated storage position to simulate and obtain the evaluation result of the storage position corresponding to the idle position. Optionally, the preset condition also includes that the evaluation result of the storage position corresponding to the idle position is less than the set evaluation threshold, then the specific implementation scheme of using the simulated storage position as the entry storage position of the container to be entered in S104 further includes: using the idle position as the entry storage position of the container to be entered, wherein the evaluation result of the storage position corresponding to the idle position is the weighted sum of the container risk and the yard space utilization rate.

[0110] After S104, S1006 is executed to update the storage status information of the yard containers, wherein the storage status information of the yard containers includes the storage location of the incoming containers and the yard map information, and the yard map information includes the storage location of all the fire lines in the yard. Figure 3 The updated yard map shown shows all the containers that have entered the yard and the containers that are to be entered. Specifically, the entry storage position T and the optimized position information P of the container that is to be entered are obtained, the entry storage position T of the container that is to be entered is loaded into the position data list of the containers that have entered the yard, and the entry storage position information of the container that is to be entered is updated. Furthermore, the updated yard map is displayed for the containers that are to be entered to perform subsequent steps.

[0111] pass Figure 1A The method for obtaining the storage position of the cargo box shown is to simulate the entry based on the acquired attribute information of the cargo box to be entered to obtain the simulated storage position and storage position evaluation result of the cargo box to be entered. When the storage position evaluation result of the simulated storage position does not meet the preset conditions, it triggers the merging and storage of multiple cargo boxes in the yard and re-obtains the simulated entry result, and uses the simulated storage position whose storage position evaluation result meets the preset conditions as the entry storage position of the cargo box to be entered, thereby realizing dynamic control and adjustment of the entry storage position of the cargo box, which helps to reduce the yard safety risk of dangerous goods containers and helps to achieve efficient storage of dangerous goods container yards. At the same time, the above technical solution is also conducive to avoiding overload operation and overstorage of the yard by setting corresponding preset conditions, preventing various safety accidents caused by illegal mixed storage and over-high stacking, and providing protection for the safety of the surrounding areas of the yard.
