Attached Figure Description

[0013] Figure 1 This is a flowchart of an automated handling and management method for a mobile loading and unloading platform according to an embodiment of the present invention. Figure 2 This is a block diagram of the automated handling management system for mobile loading and unloading platforms according to an embodiment of the present invention. Detailed Implementation

[0014] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0015] Figure 1 This is a flowchart of an automated handling and management method for a mobile loading and unloading platform according to an embodiment of the present invention.

[0016] The mobile loading and unloading platform may include K loading and unloading platforms, where K is greater than or equal to 2 and can be set according to actual conditions, for example, it can be 3.

[0017] like Figure 1 As shown, the automated handling and management method for the mobile loading and unloading platform according to an embodiment of the present invention may include the following steps: S1, after receiving the material request instruction, selects the target AGV from multiple idle AGVs within the first preset range of the material shelf.

[0018] It should be noted that when there is a shortage of material on N loading and unloading platforms, a material request command is issued, where N is greater than or equal to 1 and less than K.

[0019] In one embodiment of the present invention, selecting a target AGV from a plurality of idle AGVs within a first preset range of the material shelf specifically includes the following steps: S11, obtain the sustainable travel distance of each idle AGV within the first preset range.

[0020] In one embodiment of the present invention, obtaining the sustainable driving distance of an idle AGV vehicle specifically includes: firstly, obtaining the current power reserve of the idle AGV vehicle, and then obtaining the power consumed by the idle AGV vehicle per unit distance traveled in previous transport tasks to obtain the unit power consumption; and then obtaining the sustainable driving distance of the idle AGV vehicle based on the current power reserve and the unit power consumption.

[0021] S12, obtain the total trajectory length of the first preset trajectory and the second preset trajectory.

[0022] S13, extract from each idle AGV that has a sustainable travel distance greater than or equal to the total trajectory length as candidate AGVs.

[0023] S14: Extract the AGV closest to the material shelf from the candidate AGVs and select it as the target AGV.

[0024] Specifically, firstly, based on the sustainable travel distance and total trajectory length of each idle AGV, idle AGVs with a sustainable travel distance greater than or equal to the total trajectory length are selected from the idle AGVs within a first preset range as candidate AGVs. In other words, idle AGVs capable of traveling the total trajectory length are first selected as candidate AGVs. Then, from the candidate AGVs, the AGV closest to the material rack is selected as the target AGV. This ensures that the selected target AGV can reach the target loading area, avoiding situations where the target AGV's current power reserve is insufficient to support its journey to the target loading area, thus preventing normal loading.

[0025] S2, control the target AGV to move to the material shelf along the first preset trajectory.

[0026] S3: After the target AGV receives the target quantity of materials from the material rack, control the target AGV to move towards the target loading area along the second preset trajectory. During the movement of the target AGV, the loading and unloading platform continues to operate.

[0027] It is understood that each loading / unloading platform can hold a quantity of material of 1. Upon receiving a material request instruction, the target quantity of material required by the loading / unloading platform can be calculated in advance.

[0028] Specifically, in one embodiment of the present invention, the automated handling and management method for mobile loading and unloading platforms further includes: S31, after receiving the material request instruction, predict the time required for the target AGV to move to the target loading area according to the first preset trajectory and the second preset trajectory to obtain the first predicted time, and predict the time required for the remaining material on the loading and unloading platform currently in working state to be consumed to obtain the second predicted time.

[0029] S32, determine whether the first prediction time is less than the second prediction time.

[0030] S33, if the first prediction time is less than the second prediction time, the target quantity is the number of loading and unloading platforms that are currently in a material shortage state.

[0031] S34, if the first prediction time is greater than or equal to the second prediction time, the target quantity is the number of loading and unloading platforms currently in a material shortage state plus one.

[0032] Specifically, since the loading and unloading platforms are continuously working as the target AGV moves to the target loading area along the first and second preset trajectories, the number of loading and unloading platforms in a material shortage state when the target AGV moves to the target loading area can be determined based on the first and second prediction times. If the first prediction time is less than the second prediction time, the number of loading and unloading platforms in a material shortage state when the target AGV moves to the target loading area is the same as the number of loading and unloading platforms in a material shortage state when the target AGV starts moving, i.e., the current number of loading and unloading platforms in a material shortage state. Correspondingly, the target number is the current number of loading and unloading platforms in a material shortage state. If the first prediction time is greater than or equal to the second prediction time, the number of loading and unloading platforms in a material shortage state when the target AGV moves to the target loading area is the same as the number of loading and unloading platforms in a material shortage state when the target AGV starts moving plus one, i.e., the current number of loading and unloading platforms in a material shortage state plus one. Correspondingly, the target number is the current number of loading and unloading platforms in a material shortage state plus one.

[0033] This allows for the accurate delivery of materials to the loading and unloading platforms, thereby further ensuring the production efficiency of the equipment.

[0034] S4. When the target AGV trolley moves to the target loading area, control the loading and unloading platform to stop working, and control the target AGV trolley to load materials onto the empty platform.

[0035] Therefore, when receiving a material request and controlling the target AGV to transport materials to the target loading area, the loading and unloading platform is controlled to work continuously. When the target AGV is in the target loading area, the loading and unloading platform is controlled to stop working, thereby ensuring the production efficiency of the production equipment.

[0036] In summary, the automated handling management method for mobile loading and unloading platforms according to embodiments of the present invention, upon receiving a material request instruction, selects a target AGV from multiple idle AGVs within a first preset range of the material rack, and controls the target AGV to move to the material rack along a first preset trajectory. After the target AGV receives the target quantity of materials from the material rack, it is controlled to move towards the target loading area along a second preset trajectory. During the movement of the target AGV, the loading and unloading platform continues to operate, and after the target AGV reaches the target loading area, the platform stops operating, and the target AGV loads materials onto an empty platform. Therefore, by continuously operating the loading and unloading platform while receiving a material request and controlling the target AGV to transport materials to the target loading area, and stopping the platform only when the target AGV is in the target loading area, the production efficiency of the production equipment can be ensured.

[0037] Corresponding to the automated handling management method for mobile loading and unloading platforms in the above embodiments, the present invention also proposes an automated handling management system for mobile loading and unloading platforms.

[0038] The mobile loading and unloading platform may include K loading and unloading platforms, where K is greater than or equal to 2 and can be set according to actual conditions, for example, it can be 3.

[0039] like Figure 2 As shown, the mobile loading and unloading platform automated transport management system of this invention may include: a selection module 100, a first control module 200, a second control module 300, and a third control module 400.

[0040] The selection module 100 is used to select a target AGV from multiple idle AGVs within a first preset range of the material shelf after receiving a material request instruction; the first control module 200 is used to control the target AGV to move to the material shelf along a first preset trajectory; the second control module 300 is used to control the target AGV to move to the target loading area along a second preset trajectory after receiving the target quantity of materials from the material shelf; wherein, during the movement of the target AGV, the loading and unloading platform is controlled to continue working; the third control module 400 is used to control the loading and unloading platform to stop working after the target AGV moves to the target loading area, and to control the target AGV to load materials onto the empty loading platform.

[0041] In one embodiment of the present invention, the first control module 200 is further configured to: after receiving a material request instruction, predict the time required for the target AGV trolley to move to the target loading area according to a first preset trajectory and a second preset trajectory to obtain a first predicted time, and predict the time required for the remaining material on the loading and unloading platform currently in working state to be consumed to obtain a second predicted time; determine whether the first predicted time is less than the second predicted time; if the first predicted time is less than the second predicted time, the target quantity is the number of loading and unloading platforms currently in a material shortage state; if the first predicted time is greater than or equal to the second predicted time, the target quantity is the number of loading and unloading platforms currently in a material shortage state plus one.

[0042] In one embodiment of the present invention, the selection module 100 is specifically used to: obtain the sustainable driving distance of each idle AGV within a first preset range; obtain the total trajectory length of the first preset trajectory and the second preset trajectory; extract from each idle AGV the idle AGVs the idle AGVs whose sustainable driving distance is greater than or equal to the total trajectory length as candidate AGVs; and extract from the candidate AGVs the AGV closest to the material shelf as the target AGV.

[0043] In one embodiment of the present invention, the selection module 100 is specifically used to: obtain the current power reserve of the idle AGV; obtain the power consumed by the idle AGV for each unit distance traveled in previous handling tasks, so as to obtain the unit power consumption; and obtain the sustainable travel distance of the idle AGV based on the current power reserve and the unit power consumption.

[0044] It should be noted that for details not disclosed in the mobile loading and unloading platform automated transport management system of this invention embodiment, please refer to the details disclosed in the above-described mobile loading and unloading platform automated transport management method, which will not be elaborated here.

[0045] According to an embodiment of the present invention, the automated handling management system for mobile loading and unloading platforms, upon receiving a material request instruction, selects a target AGV from multiple idle AGVs within a first preset range on the material shelf via a selection module. A first control module controls the target AGV to move along a first preset trajectory to the material shelf. A second control module, after receiving the target quantity of materials from the material shelf, controls the target AGV to move along a second preset trajectory to the target loading area. During the movement of the target AGV, the loading and unloading platform continues to operate. A third control module, upon the target AGV reaching the target loading area, stops the loading and unloading platform and controls the target AGV to load materials onto an empty platform. Thus, by continuously operating the loading and unloading platform while receiving a material request and controlling the target AGV to transport materials to the target loading area, and stopping the platform only when the target AGV is in the target loading area, the production efficiency of the production equipment can be ensured.
