Description

Technical Field

[0001] This application relates to the field of express delivery sorting technology, and in particular to a control method for express delivery sorting. Background Technology

[0002] During the delivery process, express parcels need to be transferred in transit centers. Transit centers generally have express parcel sorting systems. The express parcel sorting system has transport carts on the loop, and storage boxes are placed near the loop. The express parcel sorting carts pick up express parcels at the inlet on the loop and transport the express parcels to the storage boxes according to the delivery destination, so that express parcels with the same delivery destination are sorted together, thus realizing the sorting and organization of express parcels.

[0003] In a parcel sorting system, sorting and transport trolleys are arranged along a single loop, with terminal collection boxes evenly distributed along the loop. The existing control center controls the trolleys to distribute parcels to multiple collection boxes along the loop. The control center only controls the trolleys to transfer the parcels to the collection boxes when it detects that the trolley has reached the location corresponding to the parcel being transported on the loop. This control method has low sorting efficiency when sorting a large number of parcels.

[0004] Therefore, how to improve the sorting efficiency of express parcels has become an urgent technical problem to be solved. Summary of the Invention

[0008] Preferably, before obtaining the loop information of the target express parcel on the target main line trolley, the express sorting control method further includes: dividing the delivery addresses of multiple express parcels into a first type of delivery address and a second type of delivery address according to the sorting frequency of multiple express parcels in the express sorting system, wherein the sorting frequency corresponding to the first type of delivery address is higher than that of the second type of delivery address; obtaining the target address of the target express parcel; determining whether the target address belongs to the first type of delivery address; if the target address belongs to the first type of delivery address, then determining the main loop as the loop information of the target express parcel; if the target address belongs to the second type of delivery address, then determining one of the branch loops as the loop information of the target express parcel.

[0009] Preferably, before determining whether the target address information belongs to the first type of receiving address, the express sorting control method further includes: acquiring the transport distance data corresponding to multiple storage boxes; determining whether the sorting frequency corresponding to the target address is lower than a preset sorting frequency threshold; if lower, determining one of the branch loops as the target transport branch loop; determining the target transport branch loop as the loop information of the target express package; and determining the storage box among the multiple storage boxes of the target transport branch loop whose transport distance data is greater than the preset distance threshold as the target storage box.

[0010] Preferably, if the loop information corresponds to one of the multiple branch loops, and the branch loop corresponding to the loop information is determined as the target branch loop, the express sorting control method further includes: determining the first alignment point of the target mainline trolley on the target mainline junction section and the second alignment point of the target branch trolley on the target branch line junction section, wherein the distance between the first alignment point and the second alignment point is less than a preset distance threshold; adjusting the travel speed of the target branch trolley according to the travel speed of the target mainline trolley, and controlling the target mainline trolley and the target branch trolley to arrive at the first alignment point and the second alignment point simultaneously; if the real-time position of the target mainline trolley is located at the target mainline junction section, controlling the target mainline trolley to transfer the target express package to the target branch trolley, further including: if the real-time position of the target mainline trolley is located at the first alignment point, controlling the target mainline trolley to transfer the target express package to the target branch trolley.

[0011] Preferably, the express sorting control method further includes: controlling the travel speed of the target main line trolley at the first alignment point to be consistent with the travel speed of the target branch line trolley at the second alignment point.

[0012] Preferably, before the target mainline trolley is transferred to the target branch line trolley when its real-time position is at the first alignment point, the express sorting control method further includes: acquiring the weight data of the target express package and the first speed data of the target mainline trolley; if the weight data of the target express package is greater than a preset weight threshold, when the real-time position of the target mainline trolley is a preset distance from the first alignment point, controlling the target mainline trolley to travel to the first alignment point at a speed of the second speed data, where the second speed data is less than the first speed data.

[0015] Preferably, the control center is used to generate control signals; guide rails are formed on both the main loop and the branch loop, and multiple conductive grooves are provided on the outer side of the guide rails along the length direction of the guide rails. The conductive grooves are used to transmit control signals; the bottom of the main line trolley and the branch line trolley are also provided with conductive wheels for embedding in the conductive grooves. The conductive wheels form a sliding connection and an electrical connection with the conductive grooves, and are used to receive control signals on the conductive grooves.

[0016] This embodiment of the application uses multiple mainline trolleys on the main loop line, allowing the control center to control the mainline trolleys to sort express parcels on the main loop line. The single loop line is divided into a main loop line and multiple branch loop lines. Each branch loop line is located close to the main loop line and has a branch line junction section close to the main loop line. This junction section can be used as the inlet for that branch loop line. After determining that the loop information of the target express parcel corresponds to one of the multiple branch loop lines, the control center can control the target branch line trolley to move to the target branch line junction section of the target branch loop line, control the target mainline trolley to move to the target mainline junction section of the main loop line, and control the target mainline trolley to transfer the target express parcel to the target branch line trolley located at the target branch line junction section. This achieves the transfer of express parcels from the main loop line to the branch loop line, allowing the control center to sort express parcels in parallel based on the main loop line and multiple branch loop lines, thereby improving the sorting efficiency of express parcels.

[0030] The control center provided in this embodiment is used to control the express delivery sorting system, such as... Figure 1 and Figure 2 As shown, the express sorting system 1 includes: a main loop line 10, on which multiple main line trolleys 12 are provided for transporting express parcels; multiple branch loop lines 20, each branch loop line 20 is set close to the main loop line 10 and has a branch line junction section 21 close to the main loop line 10, and at least one branch line trolley 22 is on each branch loop line 20; the branch line junction sections 21 on the main loop line 10 corresponding to the multiple branch loop lines 20 have multiple main line junction sections 11; multiple storage boxes 30 are respectively provided at the main loop line 10 and the branch loop lines 20.

[0031] Preferably, the outer side of the main loop line 10 is adjacent to the branch loop line 20, forming 9 sets of loop lines; storage boxes 30 are arranged inside the main loop line 10, and storage boxes 30 are arranged inside and outside the branch loop line 20.

[0032] There are 40 transport vehicle sets on the main loop line 10, with 3 mainline trolleys per set, totaling 120 trolleys; there are 8 transport vehicle sets on each branch loop line 20, with 2 branchline trolleys per set, totaling 16 trolleys. The transport trolleys circulate along their respective loop lines, and their transport routes can be found by referring to... Figure 2 The solid arrows in the diagram illustrate the handover process of express parcels on the main loop 10 and the branch loop 20. Figure 2 The dashed arrows in the diagram indicate that the main loop 10 and the eight branch loops 20 form nine internal circulation routes that work together to greatly improve sorting efficiency.

[0033] like Figure 3 As shown, a conveyor belt is arranged on the trolley of the main loop line 10 or the branch loop line 20, and the transfer of express parcels is carried out by the belt driven by the motor. Specifically, the main line trolley 12 and the branch line trolley 22 form a structure as shown in the figure. Figure 3 The solid arrow in the middle indicates a counter-clockwise transmission direction, to form as... Figure 3 The direction of the transfer of express parcels is indicated by the dashed arrow, thus completing the transfer of express parcels. The main line trolley 12 can also form a clockwise transmission direction to transfer express parcels to, for example, Figures 1-2The storage box 30, arranged inside the main loop 10, is shown. The branch trolley 22 can form a counter-clockwise transmission direction to transfer express packages to, for example,... Figures 1-2 The storage box 30, arranged inside the branch loop 20, can also form a clockwise transmission direction for transferring express parcels to, for example, Figures 1-2 The storage box 30 shown is located outside the branch loop 20.

[0034] The control center establishes communication connections with the main line trolley 12 and the branch line trolley 22 respectively, to obtain the real-time positions of the main line trolley 12 and the branch line trolley 22. The control center can also individually control multiple transport trolleys in the express sorting system 1, specifically: Figure 4 The diagram illustrates the interaction structure between the branch line trolley 22 and the loop line. The interaction structure between the main line trolley 12 and the main loop line 10 can be referenced. Figure 4 Configure settings, such as Figure 4 As shown, the control center is used to generate control signals; the main loop line 10 and the branch loop line 20 are both equipped with guide rails 40, and multiple conductive grooves 41 are provided on the outer side of the guide rails 40 along the length direction of the guide rails 40. The conductive grooves 41 are used to transmit control signals; the bottom of the main line trolley 12 and the branch line trolley 22 are also equipped with conductive wheels 42 for embedding into the conductive grooves 41. The conductive wheels 42 form a sliding connection and an electrical connection with the conductive grooves 41, and are used to receive control signals on the conductive grooves 41.

[0035] like Figure 5 In the traditional single-loop logistics sorting line shown, all carts run on a single track, connected in series by mechanical links, and densely distributed like links in a chain. They cannot be controlled individually, resulting in a large number of carts, high cost, and unstable connection issues due to the control center's wireless connection. In contrast, each cart is equipped with a power supply and communication module, receiving power and control signals through a conductive groove 41. In this embodiment, the control center can achieve relatively stable individual control of each cart based on the wired rail connection between the conductive groove 41 and the conductive wheel 42.

[0036] The main loop line 10 has four evenly spaced inlets 45 to improve the efficiency of receiving and sorting packages. When a transport trolley passes through an inlet 45, it receives express parcels. The express sorting system 1 is designed to have a receiving capacity of 10,800 parcels per hour.

[0037] Each inlet 45 is equipped with a barcode scanner. The scanner scans the barcode (either a one-dimensional or two-dimensional code) on the target parcel. The control center reads the barcode and identifies information such as the tracking number, recipient address, and parcel weight. The tracking number is then used as the parcel's identification information. After the parcel is scanned at inlet 45, the control center assigns a target mainline cart from among several idle mainline carts 12 on the main loop line 10. The target mainline cart receives the parcel at inlet 45 and transports it. The control center also associates the parcel's identification information with the pre-stored target mainline cart's identification information.

[0038] After reading the tracking code of the target parcel, the control center also needs to assign a storage box 30 to the target parcel and associate the information of the assigned storage box, the loop information of the loop where the storage box is located, and the identification information of the target parcel so that the control center can control the transportation process of the target mainline vehicle based on the real-time location of the target mainline vehicle.

[0039] Further, please refer to Figure 6 , Figure 6 This application illustrates a control method for express delivery sorting provided in an embodiment. This method is applied to a control center, which can be a main control computer system of a logistics center. Specifically, the express delivery sorting control method includes the following steps:

[0040] S110, obtain the loop information of the target express package on the target main line car, wherein the loop information is the information of the loop where the target storage box corresponding to the target express package is located.

[0041] The control center can query the loop information of the target storage box associated with the target parcel based on the identification information of the target parcel. Alternatively, the control center can query the identification information of the target parcel associated with the identification information of the target main line vehicle based on the identification information of the target main line vehicle, and then query the loop information of the target storage box associated with the identification information of the target parcel based on the identification information of the target parcel.

[0042] S120: Determine if the loop information corresponds to the main loop. If the loop information corresponds to the main loop, jump to S121 and execute the steps of S121; if the loop information corresponds to one of the multiple branch loops, jump to S130 and execute the steps of S130~S180.

[0043] If the target storage box is located on the main loop line, the loop line information corresponds to the main loop line; if the target storage box is located on the branch loop line, the loop line information corresponds to the branch loop line.

[0044] S121, control the target main line trolley to transport the target express package to the target storage box on the main loop line.

[0045] The control center controls the rotation direction of the motor of the target main line trolley to transfer the target express package on the conveyor belt to the target storage box.

[0046] S130, the branch loops corresponding to the loop information of multiple branch loops are determined as target branch loops.

[0047] S140, determine the target mainline junction segment corresponding to the target branch ring line from multiple mainline junction segments.

[0048] The information of multiple main line junctions and multiple branch line junctions are stored in the control center in pairs. Therefore, the information of the main line junctions corresponding to the target branch line can be determined based on the information of the target branch line.

[0049] S150, determine the target branch line car from the branch line cars that are in an idle state on the target branch line.

[0050] Specifically, steps S110-S120 and S130-S150 can be executed by the control center after reading the express code and before the target mainline vehicle receives the target express package from the inlet 45, or they can be executed by the control center within a short period of time after the target mainline vehicle receives the target express package from the inlet 45. In this embodiment, there is no strict limitation on the execution time of the above steps. Furthermore, the control center can execute S140 before S150, or S140 can execute S150, or S140 and S150 can be executed simultaneously. In this embodiment, there is no specific limitation on the execution order of S140 and S150.

[0051] S160, control the target branch line trolley to run to the target branch line junction section of the target branch loop.

[0052] S170, if the real-time position of the target main line vehicle is located at the junction of the target main line, then control the target main line vehicle to transfer the target express package to the target branch line vehicle.

[0053] The control center reads the position of the target mainline vehicle in real time and determines whether the read position is within the range of the target mainline junction section. If the real-time position is within the range of the target mainline junction section, it means that the target mainline vehicle has moved to the target mainline junction section; if the real-time position is not within the range of the target mainline junction section, the control center continues to read the position of the target mainline vehicle until the target mainline vehicle has moved to the target mainline junction section.

[0054] The control center continuously reads the real-time positions of the target branch line trolley and the target main line trolley. After determining that the two trolleys have met at the junction based on their real-time positions, the control center controls the conveyor belts of the two trolleys to form a... Figure 3 The direction of the transfer of the express package is indicated by the dashed arrow, thus completing the transfer of the target express package; furthermore, the transmission speed of the two trolleys can be controlled to be kept consistent to ensure the stability of the target express package during the transfer.

[0055] S180 controls the target branch line trolley to transport the target express package to the target storage box.

[0056] If the target storage box is located inside the target branch line, the control center controls the target branch line trolley 22 to form a counterclockwise transmission direction near the target storage box on the target branch line, so as to transfer the target express package into the target storage box; if the target storage box is located outside the target branch line, the control center controls the target branch line trolley 22 to form a clockwise transmission direction near the target storage box on the target branch line, so as to transfer the target express package into the target storage box, thereby completing the sorting of the target package.

[0057] This embodiment of the application provides multiple mainline trolleys 12 on the main loop line 10, enabling the control center to control the mainline trolleys 12 to sort express parcels on the main loop line. The single loop line is divided into a main loop line 10 and multiple branch loop lines 20. Each branch loop line 20 is located close to the main loop line 10 and has a branch junction section 21 close to the main loop line 10. This branch junction section 21 can be used as the inlet for the branch loop line 20. The control center determines the loop information of the target express parcel and the multiple branch loop lines. Once one of the lines is matched, the target branch line trolley can be controlled to run to the target branch line junction section of the target branch loop, and the target main line trolley can be controlled to run to the target main line junction section of the main loop. The target main line trolley can then transfer the target express parcel to the target branch line trolley located at the target branch line junction section, thereby realizing the transfer of express parcels from the main loop line 10 to the branch loop line 20. This allows the control center to sort express parcels in parallel based on the main loop line and multiple branch loop lines, thereby improving the sorting efficiency of express parcels.

[0058] To further improve the sorting efficiency of express parcels, it is advisable to categorize them into high-frequency and general parcels based on logistics conditions. Parcels with a higher frequency of occurrence at the sender's destination (i.e., the recipient's address) are classified as high-frequency parcels. Each sender's destination corresponds to one storage box 30, and the control center records the location of all storage boxes 30. For details, please refer to... Figure 7 Prior to S110, the control method for express parcel sorting also included the following steps S101~S108 to determine the target storage box for the target express parcel:

[0059] S101, based on the sorting frequency of multiple express parcels in the express sorting system, divide the delivery addresses of multiple express parcels into a first type of delivery address and a second type of delivery address. The sorting frequency of the first type of delivery address is higher than that of the second type of delivery address.

[0060] In other words, the first type of receiving address is used to characterize the destination of high-frequency sending, and the second type of receiving address is used to characterize the destination of general-frequency sending.

[0061] S102, Obtain the target address of the target express package.

[0062] S103, acquire the transport distance data corresponding to multiple storage boxes.

[0063] The starting point for calculating the transport distance data of the storage box is the inlet 45, and the ending point for calculating the transport distance data is the transfer point on the loop line closest to the storage box.

[0064] If there are multiple inlets 45, the storage box in the pre-stored data of the control center corresponds to multiple transport distance data. After obtaining the inlet of the target express package, the transport distance data corresponding to the inlet of the target express package can be used as the transport distance data corresponding to the multiple storage boxes in S103.

[0065] S104, determine whether the sorting frequency corresponding to the target address is lower than the preset sorting frequency threshold. If the sorting frequency is lower than the preset sorting frequency threshold, jump to S105a and execute steps S105a~S105c; if the sorting frequency is higher than or equal to the preset sorting frequency threshold, jump to S106.

[0066] The preset sorting frequency threshold can be set according to actual usage, for example, set to 10%.

[0067] If the sorting frequency is lower than the preset sorting frequency threshold, it indicates that the express parcel corresponding to the target address is a low-frequency parcel. Therefore, the sorting frequency of the second type of receiving address is also higher than the preset sorting frequency threshold.

[0068] S105a, one of the branch loops is identified as the target conveying branch loop.

[0069] The target delivery branch loop information is stored in the control center as the loop information of the target storage box.

[0070] S105b, the target delivery branch loop is determined as the loop information of the target express parcel.

[0071] S105c, the storage box whose transport distance data is greater than the preset distance threshold among the multiple storage boxes of the target transport branch loop is identified as the target storage box.

[0072] S106, determine whether the destination address belongs to the first type of receiving address. If the destination address belongs to the first type of receiving address, proceed to S107; if the destination address belongs to the second type of receiving address, proceed to S108.

[0073] S107, the main loop line is identified as the loop line information for the target express parcel.

[0074] Then, the target storage box for the target express parcel is allocated from the storage box at the main loop.

[0075] S108, identify one of the branch loops as the loop information for the target express parcel.

[0076] Then, the target storage box for the target express package is assigned from the storage box at the branch loop corresponding to the loop information of the target express package.

[0077] By placing high-frequency parcel collection boxes inside the main loop line, parcels are transported to the corresponding collection box positions by mainline trolleys for direct sorting. The main loop line is only 66.4 meters long, with 120 transport trolleys, and their dense arrangement allows for extremely fast sorting of high-frequency parcels.

[0078] Collection boxes for regular and low-frequency parcels are located on each branch loop line. Mainline trolleys transport parcels to their corresponding mainline junctions, where they are then transferred to target branch loop trolleys. From there, the target branch loop trolleys transport the parcels to their designated collection boxes for sorting. Each branch loop line has 16 trolleys, totaling 128, thus the overall transport capacity of the branch loop lines is higher than that of the main loop lines. Furthermore, since high-frequency parcels are already sorted on the main loop lines, the branch loop lines have significant capacity redundancy, preventing congestion on the main loop lines.

[0079] Furthermore, based on the transport distance data, the storage boxes on the branch loops with longer transport distances can be identified as target storage boxes for low-frequency express parcels, in order to further avoid congestion on the branch loops and thus improve the sorting capacity of the express parcel sorting system.

[0080] Furthermore, the control center also monitors the operational status of the target mainline trolley and the target branchline trolley in real time to improve the docking efficiency of target express parcels at the junction. Specifically, after S130, the express sorting control method also includes the following steps:

[0081] S131, determine the first alignment point of the target main line vehicle on the target main line junction section, and the second alignment point of the target branch line vehicle on the target branch line junction section, wherein the distance between the first alignment point and the second alignment point is less than a preset distance threshold.

[0082] The control center determines a first alignment point and a second alignment point, and the distance between the first alignment point and the second alignment point is less than a preset distance threshold, which ensures the stability of the target express package during transport. The preset distance threshold can be set according to usage needs, for example, 4cm.

[0083] S132, adjust the speed of the target branch line car according to the speed of the target main line car, and control the target main line car and the target branch line car to reach the first alignment point and the second alignment point simultaneously.

[0084] Specifically, the control center can achieve precise control of the trolley's speed and position through the interaction between the gears on the trolley and the rack on the other side of the guide rail.

[0085] S170 further includes the following sub-step: S173, if the real-time position of the target main line vehicle is located at the first alignment point, then control the target main line vehicle to transfer the target express package to the target branch line vehicle.

[0086] The control center controls the target mainline trolley and the target branchline trolley to simultaneously reach the first alignment point and the second alignment point, respectively. When the real-time position of the target mainline trolley is at the first alignment point, the control center controls the target mainline trolley to transfer the target express package to the target branchline trolley, which can improve the transfer efficiency of the target express package from the target mainline trolley to the target branchline trolley.

[0087] If the target mainline vehicle has not yet reached the first alignment point, the control center will continue to acquire the real-time position of the target mainline vehicle until the target mainline vehicle reaches the first alignment point, at which point S173 will be executed.

[0088] Furthermore, the control center can also execute S133 to improve the stability and efficiency of the transfer of target express parcels from the target main line vehicle to the target branch line vehicle.

[0089] S133 controls the speed of the target main line trolley at the first alignment point to be the same as the speed of the target branch line trolley at the second alignment point.

[0090] Furthermore, if the package is heavy and the trolley is moving on the track during the transfer process, extra attention needs to be paid to the stability of the transfer from the target main line trolley to the target branch line trolley. Therefore, before S173, the control method for express sorting also includes steps S171~S172:

[0091] S171, obtain the weight data of the target express package and the first speed data of the target main line vehicle.

[0092] When the control center reads the express delivery code, it stores the information such as the express delivery number, the recipient address and the package weight into the memory. When executing S171, the control center reads the weight data of the target express package. If the weight data of the target express package is greater than the preset weight threshold, for example, 10kg, the target express package is determined to be an overweight express package. For overweight express packages, the travel speed of the target main line trolley needs to be controlled during the transfer.

[0093] S172, if the weight data of the target express package is greater than the preset weight threshold, when the real-time position of the target main line vehicle is at a preset distance from the first alignment point, control the target main line vehicle to travel to the first alignment point at a speed of the second speed data, where the second speed data is less than the first speed data.

[0094] When reducing the speed of the target mainline car, the speed of the target branchline car needs to be reduced simultaneously so that the speed of the target mainline car at the first alignment point and the speed of the target branchline car at the second alignment point are consistent.

[0095] By reducing the speed of the main line vehicle, the main line vehicle can smoothly transfer the target parcel to the branch line vehicle when transferring it at the first alignment point. If the speed of the main line vehicle is not reduced, the target parcel is prone to slipping during the transfer, causing it to fall off the loop and potentially be lost.

[0096] Preferably, if the real-time position of the target mainline vehicle is located at the junction of the target mainline, then after S173, the express sorting control method further includes: S179, controlling the driving speed of the target mainline vehicle to the first speed data.

[0097] After completing the transfer of the target express package, in order to avoid further impacting other mainline vehicles on the main loop, the speed of the target mainline vehicle needs to be restored to its normal first speed.

[0098] Considering the impact of the target mainline trolley slowing down on the trolleys running behind it, preferably, the express sorting control method further includes sub-steps S174~S176:

[0099] S174 controls the driving speed of multiple mainline cars to be the first speed data.

[0100] The control center maintains the speed of the main line vehicles on the main loop at a first speed, for example, 0.8 m / s, so that collisions do not occur between multiple main line vehicles.

[0101] S175: Based on the real-time positions of the target mainline vehicle and the next mainline vehicle, determine whether the distance between the target mainline vehicle and the next mainline vehicle is less than a preset safe distance. If the distance between the target mainline vehicle and the next mainline vehicle is less than the preset safe distance, proceed to S176.

[0102] The preset safety distance can be set according to actual usage, for example, 20cm. It is necessary to judge in real time whether the target main line car and the next main line car of the target main line car are kept at a safe distance to ensure the normal operation of multiple transport cars on the main loop.

[0103] S176, control the following main line car to reduce its speed so that the distance between the following main line car and the target main line car is greater than the preset safe distance.

[0104] If the distance between the target mainline car and the next mainline car is less than the preset safe distance, the speed of the next mainline car needs to be reduced appropriately to ensure that the two cars do not collide. For example, the speed of the next mainline car can be reduced from the first speed of 0.8m / s to the second speed of 0.6m / s.

[0105] If the distance between the target mainline vehicle and the next mainline vehicle is greater than or equal to the preset safe distance, the position data between the target mainline vehicle and the next mainline vehicle will be continuously acquired in real time, and it will be determined whether the distance between the two is maintained outside the preset safe distance. Until the distance between the target mainline vehicle and the next mainline vehicle is less than the preset safe distance, the control center will execute S176 to ensure the normal operation of multiple vehicles on the main loop.
