[0055] Figure 3 This is a specific flow chart of step S1 of a control method for preventing express delivery bounce and misclassification proposed in an embodiment of the present invention. DETAILED DESCRIPTION

[0056] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation methods in conjunction with the accompanying drawings.

[0057] like Figure 1 As shown, a control method for preventing express delivery from bouncing and missorting proposed in an embodiment of the present invention includes: first, when obtaining information that the destination grid of the goods to be sorted on multiple consecutive carts is consistent, find a cart among the multiple consecutive carts that carries goods to be sorted with a weight greater than a first weight, and use it as a target cart; second, judge whether the weight of the goods to be sorted on the N carts after the target cart is less than a second weight; further, if the weight of the goods to be sorted on the N carts after the target cart is not less than the second weight, control the goods to be sorted on the N carts after the target cart to be placed in the destination grid in sequence; finally, if the weight of the N carts after the target cart is less than the second weight, control the goods to be sorted on the target cart or the goods to be sorted on the N carts after the target cart to be placed in the destination grid.

[0058] The present invention focuses on the situation where a target cart carries more than a first weight of goods to be sorted, while the N carts following the target cart carry less than a second weight of goods to be sorted, which is prone to congestion and collision at the same grid. The present invention adopts two solutions: the goods to be sorted on the target cart are lowered to the grid, while the goods to be sorted on the subsequent N carts are not lowered to the destination grid at this time, and are lowered when they arrive at the destination grid again; or, the goods to be sorted on the N carts following the target cart are controlled to be lowered to the destination grid, while the goods to be sorted on the target cart are not lowered to the destination grid at this time, and are lowered when they arrive at the destination grid again. As a result, the present invention can effectively avoid the problem of incorrect sorting caused by congestion and collision of goods at the same grid without significantly increasing costs, significantly improving sorting accuracy and transportation timeliness, and avoiding economic losses.

[0059] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0060] Specifically, the present invention provides a control method for preventing express delivery from bouncing back and being misclassified, which includes:

[0061] S1. When information is obtained that the destination slots of the goods to be sorted on multiple consecutive trolleys are consistent, a trolley carrying goods to be sorted with a weight greater than a first weight is found among the multiple consecutive trolleys to be selected as a target trolley.

[0062] Further, if Figure 2 As shown, before step S1, the following steps are also included:

[0063] F11. The weight information and identification information of each item to be sorted are collected through sensors, and the destination slot of each item to be sorted is obtained based on the identification information.

[0064] F12. By controlling the pre-set conveying speed of the cargo conveyor belt, the cargo to be sorted is delivered to different carts.

[0065] The identification information includes: QR code, barcode and RFID tag.

[0066] Further, if Figure 3 As shown, step S1 includes:

[0067] S11. Determine whether the destination slots of the goods to be sorted on multiple consecutive carts are consistent.

[0068] S12a: If the destination slots of the goods to be sorted on the multiple consecutive trolleys are inconsistent, control the goods to be sorted on the multiple consecutive trolleys to be placed to the corresponding destination slots.

[0069] S12b. If the destination bins of the goods to be sorted on the multiple consecutive carts are consistent, determine whether the weight of the goods to be sorted on each of the multiple consecutive carts exceeds the first weight.

[0070] S13a: If the weight of the goods to be sorted on each of the plurality of consecutive trolleys does not exceed the first weight, the goods to be sorted on the plurality of consecutive trolleys are controlled to be sequentially placed in the same destination slot.

[0071] S13b. If the weight of the goods to be sorted on the multiple consecutive carts exceeds the first weight, find a cart among the multiple consecutive carts that carries the goods to be sorted with a weight greater than the first weight and use it as a target cart.

[0072] S2. Determine whether the weight of the goods to be sorted on the N carts following the target cart is less than a second weight.

[0073] Before step S2, the method further includes: determining the vehicle range affected by the target vehicle, that is, the N vehicles following the target vehicle, based on the time difference of the unloading of the goods to be sorted on the adjacent vehicles. The value range of N is a positive integer of 1 to 10.

[0074] Taking into account the time difference of the goods to be sorted on adjacent carts being lowered to the grid is too small, the goods on the car behind the target cart will still bounce back and be missorted. Therefore, according to the time difference of the goods to be sorted on adjacent carts being lowered to the grid, it is set to judge N carts, N>1, and the X car and the X+1...X+N cars are judged separately. The goods to be sorted on the carts that meet the corresponding weight conditions will not be placed at the destination grid at this time and will be placed when they arrive at the destination grid again.

[0075] S3a: If the weight of the goods to be sorted on the N trolleys following the target trolley is not less than the second weight, the goods to be sorted on the N trolleys following the target trolley are controlled to be placed in the destination compartments in sequence.

[0076] S3b. If the weight of the N carts following the target cart is less than the second weight, control the goods to be sorted on the target cart or the goods to be sorted on the N carts following the target cart to be placed at the destination compartment.

[0077] Preferably, the first weight is greater than the second weight, the first weight is 1000 grams, and the second weight is 200 grams.

[0078] In a specific embodiment, considering the case where N is 1, when information is obtained that the destination slots of the goods to be sorted on the adjacent trolleys are consistent, it is determined whether the weight of the goods to be sorted on the previous trolley is greater than the first weight; if the weight of the goods to be sorted on the previous trolley is not greater than the first weight, the two goods to be sorted on the adjacent trolleys are controlled to be placed down to the destination slots in sequence; if the weight of the goods to be sorted carried by the previous trolley is greater than the first weight, the previous trolley is regarded as the target trolley, and at the same time, it is determined whether the weight of the goods to be sorted on the next trolley is less than the set first weight. Second weight; if the weight of the goods to be sorted on the rear trolley is not less than the second weight, the goods to be sorted on the adjacent trolleys are controlled to be placed at the destination grid in sequence; if the weight of the goods to be sorted on the rear trolley is less than the second weight, the goods to be sorted on the target trolley are controlled to be placed at the destination grid, and the goods to be sorted on the rear trolley are not placed at the destination grid at this time and are placed at the destination grid again; or the goods to be sorted on the rear trolley are controlled to be placed at the destination grid, and the goods to be sorted on the target trolley are not placed at the destination grid at this time and are placed at the destination grid again.

[0079] Considering that when N is 2, the target carts, i.e., carts X+1 and X+2 following cart X, will enter the anti-missorting judgment logic. After comparing the weights of the cargo on carts X, X+1, and X+2, the cargo on cart X will be moved to the destination slot. The cargo on carts X+1 and X+2 that meet the requirements will not be moved to the destination slot at this time, but will be moved to the destination slot when they arrive again. Alternatively, the cargo on cart X will not be moved to the destination slot at this time, but will be moved to the destination slot when they arrive again. The cargo on carts X+1 and X+2 will be moved to the destination slot. This ensures that light items are not missorted, while minimizing the loss of sorting efficiency.

[0080] Therefore, based on the average value of the time difference between the unloading grids of the goods to be sorted on adjacent carts, and considering that setting the N value too large will have a certain impact on the sorting efficiency, a comprehensive consideration of setting the N value to 3 is the best solution to take into account the sorting efficiency while preventing rebound and missorting.

[0081] On the other hand, the present invention also provides a control system for preventing express delivery from bouncing back and being misclassified, comprising:

[0082] The cargo conveyor belt delivers the cargo to be sorted in the sorting area to different carts according to the received speed control instructions.

[0083] The sorting track is configured as a closed track with a starting point and an end point that overlap. Preferably, the sorting track is a single-line track or a double-line track.

[0084] The trolleys move along the circular sorting track, equipped with a conveyor belt that moves perpendicular to the direction of travel and unloads goods. The number of trolleys can be adjusted according to the sorting volume. The trolleys can be autonomous robots with cargo unloading devices, such as automated guided vehicles (AGVs), or controlled robots with only cargo unloading devices. Under the control of the main control platform, they can complete functions such as traveling a predetermined distance along the sorting track and pausing.

[0092] Furthermore, the anti-misclassification judgment unit includes:

[0096] The second delivery determination subunit based on the second weight is used to control the goods to be sorted on the target cart or the goods to be sorted on the N carts after the target cart to be dropped to the destination grid if the weight on the N carts after the target cart is less than the second weight.

[0097] Furthermore, the target vehicle determination subunit includes:

[0098] The slot judgment module is used to judge whether the destination slots of the goods to be sorted on multiple consecutive carts are consistent.

[0099] The initial delivery determination module is used to control the goods to be sorted on multiple consecutive trolleys to be delivered to the corresponding destination slots if the destination slots of the goods to be sorted on multiple consecutive trolleys are inconsistent.

[0100] The judgment module based on the first weight is used to judge whether the weight of the goods to be sorted on each of the plurality of consecutive trolleys exceeds the first weight if the destination slots of the goods to be sorted on the plurality of consecutive trolleys are consistent.

[0101] The first weight-based delivery determination module is used to control the goods to be sorted on the multiple consecutive trolleys to be dropped to the same destination slot in sequence if the weight of the goods to be sorted on each trolley does not exceed the first weight.

[0102] The target trolley determination module is used to find a trolley among the continuous plurality of trolleys that carries a weight of goods to be sorted greater than the first weight if the weight of the goods to be sorted on the trolley exceeds a first weight, and use it as the target trolley.

[0103] Furthermore, the anti-misclassification judgment unit includes: a subunit for determining the vehicle range affected by the target car, which is used to determine the vehicle range affected by the target car, that is, the N cars behind the target car, based on the time difference of the unloading of the goods to be sorted on the adjacent cars.

A control system for preventing express delivery from bouncing back and misclassifying, characterized in that: The system applies the control method for preventing express delivery bounce and misclassification according to any one of claims 1 to 5, and the system includes: The cargo conveyor belt delivers the cargo to be sorted in the sorting area to different carts according to the received speed control instructions; The sorting track is configured as a closed track with the starting point and the end point coincident; The trolley moves along the circular sorting track, and is equipped with a conveyor belt that moves vertically with the direction of travel and can deliver goods to the grid; A sorting channel is configured to be parallel to at least a portion of the sorting track, and along the conveying direction of the sorting track, the sorting channel is provided with a plurality of grids for docking with the goods to be sorted; and The main control platform is connected to the cargo conveyor tracks and the trolley respectively; The main control platform includes: An information receiving unit, used to collect weight information and identification information of each item to be sorted through sensors; A target slot determining unit is used to obtain the target slot for the goods to be sorted according to the identification information; A crawler speed control unit is used to control the conveying speed of the cargo conveyor crawler to deliver the cargo to be sorted in the sorting area to different carts; The anti-missorting judgment unit is used to determine the target trolley based on the weight information of the goods to be sorted on the trolleys when the destination slots of the goods to be sorted on multiple consecutive trolleys are the same, and to execute the anti-missorting judgment logic on the subsequent trolleys of the target trolley based on the target trolley to avoid the goods to be sorted on the subsequent trolleys being mistakenly sorted to other slots.

7. The control system for preventing express delivery from rebounding and mis-sorting as claimed in claim 6, characterized in that: The anti-misclassification judgment unit includes: The target trolley determination subunit is configured to, upon obtaining information that the destination slots of the goods to be sorted on multiple consecutive trolleys are consistent, find a trolley among the multiple consecutive trolleys carrying goods to be sorted with a weight greater than a first weight, and use it as the target trolley; A judgment subunit based on the second weight is used to judge whether the weight of the goods to be sorted on the N trolleys following the target trolley is less than the second weight; The first delivery determination subunit based on the second weight is configured to control the goods to be sorted on the N trolleys following the target trolley to be sequentially delivered to the destination slots if the weight of the goods to be sorted on the N trolleys following the target trolley is not less than the second weight; The second delivery determination subunit based on the second weight is used to control the goods to be sorted on the target cart or the goods to be sorted on the N carts after the target cart to be dropped to the destination grid if the weight on the N carts after the target cart is less than the second weight.

8. The control system for preventing express delivery from rebounding and mis-sorting as claimed in claim 7, characterized in that: The target vehicle determination subunit includes: The slot judgment module is used to judge whether the destination slots of the goods to be sorted on multiple consecutive carts are consistent; The initial delivery judgment module is used to control the delivery of the goods to be sorted on multiple consecutive trolleys to the corresponding destination slots if the destination slots of the goods to be sorted on multiple consecutive trolleys are inconsistent; A judgment module based on the first weight is used to judge whether the weight of the goods to be sorted on each of the plurality of consecutive trolleys exceeds the first weight if the destination slots of the goods to be sorted on the plurality of consecutive trolleys are consistent; A first weight-based delivery determination module is configured to control the goods to be sorted on the plurality of consecutive trolleys to be sequentially delivered to the same destination slot if the weight of the goods to be sorted on each of the plurality of consecutive trolleys does not exceed the first weight; The target trolley determination module is used to find a trolley among the consecutive trolleys whose weight of the goods to be sorted is greater than the first weight if the weight of the goods to be sorted on the trolley exceeds the first weight, and use it as the target trolley.

9. The control system for preventing express delivery from rebounding and mis-sorting as claimed in claim 7, characterized in that: The anti-misclassification judgment unit includes: The target car's impact vehicle range determination subunit is used to determine the target car's impact vehicle range, that is, the N cars behind the target car, based on the time difference between the unloading of the goods to be sorted on the adjacent cars. The value of N is a positive integer ranging from 1 to 10.

10. The control system for preventing express delivery from bouncing back and being missorted according to any one of claims 6 to 9, characterized in that: include: Weighing sensors and identification devices are set in the area to be sorted, and the identification device includes one or more of an RFID reader, a tag scanning device and an image sensor.
