[0021] The control center provided in the embodiment of the present application is used to control the express sorting system, such as Figure 1 and Figure 2 As shown, the express sorting system 1 includes: a main loop line 10, on which a plurality of main line trolleys 12 are arranged, and the main line trolleys 12 are used to transport express parcels; a plurality of branch loop lines 20, each of which is arranged close to the main loop line 10 and has a branch line bordering section 21 close to the main loop line 10, and there is at least one branch line trolley 22 on the branch loop line 20; the main loop line 10 has a plurality of main line bordering sections 11 corresponding to the branch line bordering sections 21 of the plurality of branch loop lines 20; and a plurality of storage boxes 30 are respectively arranged at the main loop line 10 and the branch loop lines 20.

[0022] Preferably, the outer side of the main loop line 10 is adjacent to the branch loop line 20 to form 9 sets of loop lines; the storage box 30 is arranged on the inner side of the main loop line 10, and the storage boxes 30 are arranged on the inner and outer sides of the branch loop line 20.

[0023] There are 40 transport vehicle groups on the main loop line 10, each with 3 main line trolleys 12, a total of 120 trolleys; there are 8 transport vehicle groups on each branch loop line 20, each with 2 branch line trolleys 22, a total of 16 trolleys. The transport trolleys are transported along their respective loop lines in a cycle, and their transport routes can be referred to Figure 2 The solid arrows in the figure show the handover process of express parcels on the main loop line 10 and the branch loop line 20. Figure 2 The main loop line 10 and the eight sets of branch loop lines 20 form nine sets of inner circulation routes, which work together to greatly improve the sorting efficiency.

[0024] like Figure 3 As shown, a transmission belt is arranged on the trolley of the main loop line 10 or the branch loop line 20, and the belt is driven by a motor to transfer the express parcels. Specifically, the main line trolley 12 and the branch line trolley 22 form a transmission belt. Figure 3 The solid arrow in the middle shows the counterclockwise transmission direction to form a Figure 3 The transfer direction of the express parcel shown in the direction of the dotted arrow in the middle is used to complete the transfer of the express parcel. The main line trolley 12 can also form a clockwise transmission direction to transfer the express parcel to Figure 1~Figure 2 As shown in the storage box 30 arranged inside the main loop line 10, the branch line trolley 22 can form a counterclockwise transmission direction for transferring express parcels to Figure 1~Figure 2 The storage box 30 arranged inside the branch line 20 can also form a clockwise transmission direction for transferring express parcels to Figure 1~Figure 2 As shown, it is arranged in a storage box 30 outside the branch loop line 20.

[0025] The control center establishes communication connections with the main line trolley 12 and the branch line trolley 22 respectively, so as to obtain the real-time positions of the main line trolley 12 and the branch line trolley 22. The control center can also realize individual control of multiple transport trolleys in the express sorting system 1, specifically: Figure 4 The structure of the cooperation between the trolley and the loop line is illustrated by taking the branch line trolley 22 as an example. The structure of the cooperation between the main line trolley 12 and the main loop line 10 can be referred to Figure 4 Make 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 formed with guide rails 40, and a plurality of conductive grooves 41 are provided on the outer side of the guide rails 40 along the length direction of the guide rails 40, and 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 provided with conductive wheels 42 for embedding in the conductive grooves 41, and the conductive wheels 42 form a sliding connection and an electrical connection with the conductive grooves 41 for receiving control signals on the conductive grooves 41.

[0026] like Figure 5 All the carts on the traditional single-loop logistics sorting line shown run on a single track, are connected in series through mechanical connections, and are densely distributed and arranged like chain links. They cannot be controlled individually. There are many carts and the cost is high. In addition, the control center controls the carts based on wireless connections, which has the problem of unstable connection. The cart is provided with a power supply and communication module, which is connected to electricity and receives control signals through a conductive slot 41. In the embodiment of the present application, the control center can achieve relatively stable individual control of each cart based on the wired electric track connection between the conductive slot 41 and the conductive wheel 42.

[0027] The main loop 10 is evenly arranged with four inlets 45 to improve the efficiency of inlet and sorting. The transport vehicle receives express parcels when passing through the inlet 45. The receiving capacity of the express sorting system 1 can reach 10,800 pieces / hour.

[0028] Each entry port 45 is equipped with a code scanning device, which scans the express code in the form of a one-dimensional or two-dimensional code on the target express package. The control center reads the express code, identifies the express order number, the receiving address, the package weight and other information of the express code, and uses the read express order number as the identification information of the target express package. After the target express package is scanned from the entry port 45, the control center allocates a target main line trolley from a plurality of idle main line trolleys 12 on the main loop line 10 to the target express package, and the target main line trolley receives the target express package at the entry port 45 for transportation. The control center also associates the identification information of the target express package with the identification information of the pre-stored target main line trolley.

[0029] After reading the express code of the target express parcel, the control center also needs to allocate a storage box 30 for the target express parcel, and associate the allocated target storage box information, the loop line information of the loop line where the target storage box is located, and the identification information of the target express parcel, so that the control center can control the transportation process of the target main line trolley based on the real-time position of the target main line trolley.

[0030] For further information, please refer to Figure 6 , Figure 6 The control method of express sorting provided in the embodiment of the present application is shown, and the control method of express sorting is applied to a control center, wherein the control center can be a computer system of a main control type of a logistics center. Specifically, the control method of express sorting includes the following steps: S110, obtaining loop line information of a target express package on a target main line vehicle, wherein the loop line information is information of a loop line where a target storage box corresponding to the target express package is located.

[0031] The control center queries the loop line information of the target storage box associated with the identification information based on the identification information of the target express package. The control center may also query the identification information of the target express package associated with the identification information of the target mainline trolley based on the identification information of the target mainline trolley, and then query the loop line information of the target storage box associated with the identification information based on the identification information of the target express package.

[0032] S120, determine whether the loop information corresponds to the main loop. If the loop information corresponds to the main loop, jump to S121 and execute the step of S121; if the loop information corresponds to one of the multiple branch loops, jump to S130 and execute the steps of S130 to S180.

[0033] If the target storage box is located at the main loop line, the loop line information corresponds to the main loop line, and if the target storage box is located at the branch loop line, the loop line information corresponds to the branch loop line.

[0034] S121, controlling the target main line trolley to transport the target express package to the target storage box on the main loop line.

[0035] The control center controls the rotation direction of the motor of the target main line trolley to transfer the target express package on the transmission belt to the target storage box.

[0036] S130, determining a branch loop line corresponding to the loop line information among the plurality of branch loop lines as a target branch loop line.

[0037] S140, determining a target main line bordering section corresponding to the target branch loop line from the plurality of main line bordering sections.

[0038] The information of the plurality of main line bordering sections and the information of the plurality of branch line bordering sections are stored in the control center in association with each other. Therefore, the information of the main line bordering section corresponding to the target branch line can be determined according to the information of the target branch line.

[0039] S150, determining a target branch line trolley from the branch line trolleys in an idle state on the target branch line.

[0040] Among them, steps S110~S120 and steps S130~S150 can be executed by the control center after reading the express code and before the target main line cart receives the target express package from the feed port 45, or can be executed by the control center within a short period of time after the target main line cart receives the target express package from the feed port 45. The execution time of the above steps is not strictly restricted in the embodiments of the present application; and the control center can execute S140 before S150, or execute S150 after S140, or execute S140 and S150 at the same time. The execution order of S140 and S150 is not specifically limited in the embodiments of the present application.

[0041] S160, controlling the target branch line trolley to run to the target branch line bordering section of the target branch loop line.

[0042] S170, if the real-time position of the target main line trolley is located at the target main line bordering section, the target main line trolley is controlled to transfer the target express parcel to the target branch line trolley.

[0043] The control center reads the position of the target mainline trolley in real time and determines whether the real-time position read is within the position range of the target mainline bordering section. If the real-time position is within the position range of the target mainline bordering section, it means that the target mainline trolley has moved to the target mainline bordering section; if the real-time position is not within the position range of the target mainline bordering section, the control center continues to read the position of the target mainline trolley until the target mainline trolley has moved to the target mainline bordering section.

[0044] The control center continuously reads the real-time position of the target branch line trolley and the real-time position of the target main line trolley. After determining that the two trolleys meet at the border through the real-time position of the target branch line trolley and the real-time position of the target main line trolley, the control center controls the transmission belts of the two trolleys to form the following Figure 3 The transfer direction of the express package is shown in the direction of the dotted arrow, thereby completing the transfer of the target express package; further, the transmission speed of the transmission belts of the two carts can be controlled to remain consistent to ensure the stability of the target express package during transfer.

[0045] S180, controlling the target branch line vehicle to transport the target express package to the target storage box.

[0046] If the target storage box is located on the inner side of the target branch loop line, the control center controls the target branch line trolley 22 to form a counterclockwise transmission direction on the target branch loop line close to the target storage box to transfer the target express parcel to the target storage box; if the target storage box is located on the outer side of the target branch loop line, the control center controls the target branch line trolley 22 to form a clockwise transmission direction on the target branch loop line close to the target storage box to transfer the target express parcel to the target storage box, thereby completing the sorting of the target parcel.

[0047] In the embodiment of the present application, a plurality of main line trolleys 12 are arranged on the main loop line 10, so that the control center can control the main line trolleys 12 to complete the sorting of express parcels on the main loop line; the single loop line is divided into the main loop line 10 and a plurality of branch loop lines 20, each of which is arranged close to the main loop line 10 and has a branch line bordering section 21 close to the main loop line 10, so that the branch line bordering section 21 on the branch loop line 20 can be used as the entry port of the branch loop line 20, and the control center judges the loop line information of the target express parcel and the plurality of branch loop lines. After one of the lines corresponds, the target branch line trolley can be controlled to run to the target branch line bordering section of the target branch loop line, the target main line trolley can be controlled to run to the target main line bordering section of the main loop line, and the target main line trolley can be controlled to transfer the target express parcel to the target branch line trolley located at the target branch line bordering section at the target main line bordering section, so as to realize the handover of the express parcel from the main loop line 10 to the branch loop line 20, so that the control center can sort the express parcels based on the main loop line and multiple branch loop lines in parallel, thereby improving the sorting efficiency of the express parcels.

[0048] In order to further improve the sorting efficiency of express parcels, it is possible to consider dividing express parcels into two categories: high-frequency and general according to the logistics situation. Express parcels with a high frequency of sending destinations (i.e., receiving addresses) are high-frequency parcels. Each sending destination corresponds to a storage box 30, and the control center records the positions of all storage boxes 30. For details, please refer to Figure 7 Before S110, the express sorting control method further includes the following steps S101 to S108 to determine the target storage box for the target express package: S101, according to the sorting frequencies of the multiple express parcels in the express sorting system, divide the recipient addresses of the multiple express parcels into first-category recipient addresses and second-category recipient addresses, the sorting frequency corresponding to the first-category recipient addresses being higher than that of the second-category recipient addresses.

[0049] That is, the first type of recipient address is used to represent high-frequency sending destinations, and the second type of recipient address is used to represent general frequency sending destinations.

[0050] S102, obtaining the target delivery address of the target express package.

[0051] S103, obtaining the transport distance data corresponding to the plurality of storage boxes.

[0052] The starting point for calculating the transport distance data of the storage box is the entry port 45, and the end point for calculating the transport distance data is the transfer point on the loop line close to the storage box.

[0053] If there are multiple feeding ports 45, the control center's pre-stored data will correspond to multiple transport distance data for the storage box. After obtaining the feeding port of the target express package, the transport distance data corresponding to the feeding port of the target express package can be used as the transport distance data corresponding to the multiple storage boxes in S103.

[0054] 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 to S105c; if the sorting frequency is higher than or equal to the preset sorting frequency threshold, jump to S106.

[0055] The preset sorting frequency threshold may be set according to actual usage, for example, to 10%.

[0056] 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 recipient address is also higher than the preset sorting frequency threshold.

[0057] S105a, determining one of the branch loops as the target transmission branch loop.

[0058] The target conveying branch loop line information is stored in the control center as loop line information of the loop line where the target storage box is located.

[0059] S105b, determining the target delivery branch loop line as the loop line information of the target express package.

[0060] S105c: Determine, among the multiple storage boxes on the target transport branch line, a storage box whose transport distance data is greater than a preset distance threshold as a target storage box.

[0061] S106, judging whether the target address belongs to the first category of receiving addresses. If the target address belongs to the first category of receiving addresses, jumping to S107; if the target address belongs to the second category of receiving addresses, jumping to S108.

[0062] S107, determining the main loop line as the loop line information of the target express package.

[0063] Then, the target storage box for the target express package is allocated from the storage box at the main loop line.

[0064] S108, determining one of the branch loops as the loop information of the target express package.

[0065] Then, the target storage box of the target express package is allocated from the storage box at the branch loop corresponding to the loop line information of the target express package.

[0066] By placing the high-frequency parcel storage boxes inside the main loop, the main line trolleys transport them to the corresponding storage box positions for direct sorting. The main loop is only 66.4 meters long, with 120 transport trolleys. The dense arrangement enables high-frequency parcels to be sorted very quickly.

[0067] The storage boxes for general frequency and low frequency packages are arranged on each branch line. The main line trolley transports express parcels to the corresponding main line bordering section, and ferries the express parcels to the target branch line trolley of the corresponding branch line at the main line bordering section, and then the target branch line trolley transports them to the corresponding target storage box for sorting. Each set of branch line transport trolleys has 16 units, totaling 128 units, so the overall transportation capacity of the branch line is higher than that of the main line. In addition, high frequency packages have been sorted on the main line, and the transportation capacity of the branch line is relatively redundant, so there will be no congestion on the main line.

[0068] Furthermore, storage boxes on branch loop lines with longer transportation distances can be determined as target storage boxes for low-frequency express parcels based on the transportation distance data, so as to further avoid congestion on the branch loop lines, thereby improving the sorting capacity of the express sorting system.

[0069] Furthermore, the control center also performs real-time control on the running status of the target main line trolley and the target branch line trolley to improve the docking efficiency of the target express parcel at the junction. Specifically, after S130, the control method for express sorting further includes the following steps: S131, determining a first alignment point of a target mainline vehicle on a target mainline bordering section, and a second alignment point of a target branchline vehicle on a target branch line bordering section, wherein a distance between the first alignment point and the second alignment point is less than a preset distance threshold.

[0070] The control center determines the first alignment point and the second alignment point, and the distance between the first alignment point and the second alignment point is less than the preset distance threshold, which can ensure the stability of the target express package during ferrying. The preset distance threshold can be set according to usage needs, for example, 4 cm.

[0071] S132, adjusting the travel speed of the target branch line trolley according to the travel speed of the target main line trolley, and controlling the target main line trolley and the target branch line trolley to reach the first alignment point and the second alignment point respectively at the same time.

[0072] Specifically, the control center can achieve precise control of the running speed and position of the trolley through the cooperation between the gear on the trolley and the rack on the other outer side of the guide rail.

[0073] S170, further includes a sub-step: S173, if the real-time position of the target main line trolley is located at the first alignment point, the target main line trolley is controlled to transfer the target express package to the target branch line trolley.

[0074] The control center controls the target mainline trolley and the target branch line trolley to reach the first alignment point and the second alignment point respectively at the same time, and when the real-time position of the target mainline trolley is at the first alignment point, controls the target mainline trolley to transfer the target express package to the target branch line trolley, thereby improving the transfer efficiency of the target express package from the target mainline trolley to the target branch line trolley.

[0075] If the target mainline trolley has not yet reached the first alignment point, the control center continues to obtain the real-time position of the target mainline trolley until the target mainline trolley reaches the first alignment point, and then executes S173.

[0076] Furthermore, the control center may also execute S133 to improve the stability and transfer efficiency of the target express parcel from the target main line vehicle to the target branch line vehicle.

[0077] Among them, S133 controls the driving speed of the target main line trolley at the first alignment point to be consistent with the driving speed of the target branch line trolley at the second alignment point.

[0078] Furthermore, if the weight of the express parcel is heavy and the trolley is in motion on the track during the docking process, it is necessary to pay extra attention to the stability of the transfer of the target express parcel 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: S171, obtaining the weight data of the target express package and the first speed data of the target main line vehicle.

[0079] When reading the express code, the control center stores the express number, delivery address, package weight and other information of the identified express code 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 the overweight express package, it is necessary to control the driving speed of the target main line vehicle during the transfer.

[0080] S172, if the weight data of the target express package is greater than the preset weight threshold, then when the real-time position of the target mainline vehicle is at a preset distance from the first alignment point, the target mainline vehicle is controlled to travel to the first alignment point at a speed of the second speed data, and the second speed data is less than the first speed data.

[0081] When reducing the travel speed of the target mainline trolley, it is necessary to simultaneously reduce the travel speed of the target branch line trolley so that the travel speed of the target mainline trolley at the first alignment point and the travel speed of the target branch line trolley at the second alignment point are consistent.

[0082] By reducing the driving speed of the target mainline trolley, the target express parcel can be ferried to the target branch line trolley more smoothly when the target mainline trolley transfers the target express parcel at the first alignment point; if the driving speed of the target mainline trolley is not reduced, the target express parcel is prone to slipping during ferrying, causing the target express parcel to fall off the loop line, and then causing the target express parcel to be lost.

[0083] Preferably, if the real-time position of the target main line trolley is located at the target main line bordering section, then after S173, the express sorting control method further includes: S179, controlling the travel speed of the target main line trolley to be the first speed data.

[0084] After completing the ferrying of the target express package, in order not to cause further impact on other main line vehicles on the entire main loop line, the speed of the target main line vehicle needs to be restored to the normal first speed.

[0085] Considering the impact of the target main line trolley's speed reduction on the trolleys running behind, preferably, the express sorting control method further includes sub-steps S174 to S176: S174, controlling the running speeds of multiple main line vehicles to be the first speed data.

[0086] The control center maintains the travel speed of the main line trolleys on the main loop line at the first speed, for example, 0.8m / s, so that there will be no collision between multiple main line trolleys.

[0087] S175, according to the real-time positions of the target mainline trolley and the mainline trolley behind the target mainline trolley, determine whether the distance between the target mainline trolley and the mainline trolley behind is less than the preset safety distance. If the distance between the target mainline trolley and the mainline trolley behind is less than the preset safety distance, jump to S176.

[0088] Among them, 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 mainline trolley and the next mainline trolley after the target mainline trolley maintain a safe distance to ensure the normal operation of multiple transport trolleys on the main loop line.

[0089] S176, controlling the following mainline trolley to reduce the running speed so that the distance between the following mainline trolley and the target mainline trolley is greater than the preset safety distance.

[0090] If the distance between the target mainline car and the following mainline car is less than the preset safety distance, the speed of the following mainline car needs to be reasonably reduced to ensure that the two cars do not collide. For example, the speed of the following mainline car can be reduced from the first speed of 0.8m / s to the second speed of 0.6m / s.

[0091] If the distance between the target mainline trolley and the next mainline trolley is greater than or equal to the preset safety distance, the position data between the target mainline trolley and the next mainline trolley is continuously acquired in real time, and it is determined whether the distance between the two is maintained outside the preset safety distance, until the distance between the target mainline trolley and the next mainline trolley is less than the preset safety distance, then the control center executes S176 to ensure the normal operation of multiple trolleys on the main loop line.
