Detailed Description
Exemplary embodiments of the present invention are described below with reference to the accompanying drawings, in which various details of embodiments of the invention are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.
The embodiment of the invention provides a method for determining a scheduling mode of sorting equipment, which can be used for a scene of scheduling the sorting equipment. For example, in a warehouse, a plurality of work stations are usually provided, and the sorting equipment needs to sort the articles of each work station into each container of the warehouse, so how to determine the scheduling manner of each sorting equipment, and making the balanced scheduling of each sorting equipment become an important issue.
An embodiment of the present invention provides a method for determining a scheduling manner of a sorting device, where the method may be performed by a scheduling center in a sorting system, as shown in fig. 1, and the method includes the following steps.
S101: and dividing the target area into at least two work station groups according to the position information of the work stations in the target area.
The target area may be a work station that needs to dispatch the sorting equipment to sort the articles and an area that can be reached by the sorting equipment, such as a warehouse or the like. The sorting equipment loads the articles from the workstations and automatically transports the articles in the workstations to the destination of the articles for the purpose of sorting the articles in the workstations. In order to balance the dispatching sorting equipment, the work stations in the target area are grouped, namely the target area is divided into at least two work station groups according to the position information of the work stations in the target area. The distribution of the workstations can be determined according to the position information of the workstations in the target area, and the manner of dividing the workstation groups in the embodiment of the present invention is not limited. Specifically, the workstations at a short distance may be divided into a group.
In an implementation manner of the embodiment of the present invention, the scheduling of the sorting device is usually used in a scene of sorting the articles in the warehouse, and the work stations are usually arranged on two opposite sides of the warehouse in the warehouse, that is, the work stations arranged in the warehouse are symmetrical with respect to a certain line in the warehouse, so that the work stations may be divided into two work station groups based on the symmetrical line in the embodiment of the present invention. The method specifically comprises the following steps: determining a symmetry line according to the position information of the workstations in the target area, and dividing the workstations in the target area into a first workstation group and a second workstation group based on the symmetry line; the first work station group and the second work station group are symmetrical relative to a symmetrical line.
Since the workstations in the target area are distributed with respect to the line of symmetry, i.e. the workstations in the target area can be divided into two parts based on the line of symmetry, the workstations can be divided into two groups of workstations, a first group of workstations and a second group of workstations, based on the line of symmetry.
It should be noted that, in the embodiment of the present invention, the manner in which the first station group and the second station group are symmetric with respect to the symmetry line may include multiple manners, for example, the partial stations in the first station group are symmetric with respect to the symmetry line of the partial stations in the second station group, or the stations in the first station group are symmetric with respect to the symmetry line of the partial stations in the second station group within an allowable error range, or a line to which the positions of the partial stations in the first station group belong and a line to which the positions of the stations in the second station group belong are symmetric with respect to each other, or a combination of the above symmetric manners. The line of symmetry can be determined based on the various symmetry modes described above.
S102: and determining the division ratio of the sorting equipment corresponding to each work station group based on the number of the work stations in each work station group.
After the workstation groups are divided in step S102, the division ratio of the sorting equipment corresponding to each workstation group may be determined according to the number of workstations included in each workstation group. The division ratio is the ratio of dividing the whole sorting equipment into each work station group to serve the sorting equipment, so that the sorting equipment serving each work station group is distributed according to the number of the work stations in the work station group, and the problem that the dispatching of the sorting equipment is unbalanced due to the fact that a plurality of sorting equipment are concentrated and are connected with one or more work stations is solved.
S103: and determining the position information of each sorting device in the target area under the working state.
In this case, the sorting devices in the target area transport the articles to the destination, so the positions of the sorting devices are not necessarily fixed, and therefore, the position information of each sorting device needs to be determined. Moreover, the sorting devices in the target area are not in real time working status, some sorting devices may need to go to charge or go off-line, and the sorting devices do not continue to sort the articles subsequently, so the sorting devices which are not in working status are not in the scheduling range, and therefore the position information of each sorting device in working status is determined in the step.
Because the sorting equipment needs to transport the articles to the destination before returning to the workstation to work after loading the articles, the sorting equipment in the transportation process is dispatched according to the current position of the sorting equipment, so that the distance between the destination transported by the sorting equipment and the workstation for determining subsequent service is sometimes far, the moving distance of the sorting equipment is increased, and the sorting time is increased. Therefore, in an implementation manner of the embodiment of the present invention, when the sorting device is in a state of transporting articles, the step may be specifically performed as: and taking the destination information of the articles transported by the sorting equipment as the position information of the sorting equipment.
Because the sorting equipment in the state of transporting the articles can determine the next service workstation after the transported articles reach the destination, in order to avoid increasing the moving distance of the sorting equipment and increasing the sorting time, the destination information of the transported articles of the sorting equipment can be used as the position information of the sorting equipment.
S104: and determining the work station groups respectively served by the sorting equipment based on the position information and the division ratio of the sorting equipment.
After the position information of each sorting device is determined, the distribution of the sorting devices can be known, and then the sorting devices are divided according to the dividing proportion, so that the work station groups respectively served by the sorting devices are determined. Generally, to reduce the moving distance of the sorting equipment, the sorting equipment close to each workstation group can be allocated to serve the workstation group according to the principle of proximity, and then the workstation group respectively served by each sorting equipment is determined by dividing the ratio.
Specifically, the position information includes coordinates with respect to the line of symmetry. In the embodiment of the present invention, in step S101, the first station group and the second station group may be divided by determining a symmetry line, and then in this step, based on the symmetry line, a dividing line parallel to the symmetry line is determined according to a dividing ratio according to coordinates of each sorting device, and a first area including the first station group and a second area including the second station group are divided by using the dividing line as a boundary, so that it is determined that the sorting device in the first area serves the first station group and the sorting device in the first area serves the first station group based on a principle of proximity.
In an implementation manner of the embodiment of the present invention, determining a dividing line parallel to a symmetric line based on coordinates and a dividing ratio of sorting equipment may be performed as: arranging the coordinates of all sorting equipment according to the size sequence; determining the coordinates of the dividing lines relative to the symmetrical lines based on the sequence and the dividing proportion; and determining the dividing line based on the symmetrical line and the coordinates of the dividing line relative to the symmetrical line.
After the symmetry line is determined, the coordinates of each sorting device in the direction perpendicular to the symmetry line, that is, the coordinate information of each sorting device relative to the symmetry line, can be determined by taking the symmetry line as a 0-point reference. The sorting equipment can be used for sorting according to the size of the coordinates after the coordinates of the sorting equipment are determined, and because the sorting equipment is divided according to the dividing proportion, the coordinates of the dividing line in the direction perpendicular to the symmetrical line can be determined according to the sorted coordinates and the dividing proportion, namely the coordinates of the dividing line relative to the symmetrical line, and then the dividing line parallel to the symmetrical line can be determined along the coordinates of the dividing line relative to the symmetrical line.
It should be noted that, the method for determining the scheduling manner of the sorting equipment in the embodiment of the present invention may be periodically executed, so as to implement the adjustment of the scheduling manner of the sorting equipment according to the states of the workstations and the sorting equipment in the target area. A typical cycle time may be set to the time for the sorting equipment to sort an item once, such as 30 seconds or 50 seconds. After determining the sorting equipment serving each station group, for the stations in each station group, the sorting equipment may be allocated according to the most recent queue bit strategy to finally determine which sorting equipment ultimately serves which station. After the working station group served by each sorting device is determined in each period, when the request information of the sorting device is received in the period to request the next queuing working station, the scheduling center can determine the working station to be queued by the sorting device based on the result determined by the embodiment of the invention and by combining the strategies such as the most recent queuing position and the like.
In the embodiment of the invention, the work station groups are divided according to the position information of the work stations, and then the sorting equipment serving each work station group is determined according to the number of the work stations of each work station group and the position information of the sorting equipment. The sorting equipment is distributed according to the number of the middle work stations of each work station group, the fact that the sorting equipment is concentrated on some work stations is avoided, the sorting equipment is distributed according to the position information of the sorting equipment, the position of the sorting equipment can be fully considered, the moving distance of the sorting equipment is reduced, sorting time is saved, and balanced scheduling of the sorting equipment is guaranteed.
The embodiment of the present invention may be used in the scenario shown in fig. 2, as shown in fig. 2, the target area is a warehouse as an example, and if 5 workstations are arranged in the warehouse, respectively arranged on opposite sides of the warehouse, and the workstation 1 and the workstation 2 are arranged on the left side, and the workstation 3, the workstation 4 and the workstation 5 are arranged on the right side, the symmetry line shown in fig. 2 may be determined based on the position information of the workstations.
The following specifically describes the method for determining the scheduling manner of the sorting equipment in the embodiment of the present invention with reference to the embodiment shown in fig. 1 and the scene schematic diagram shown in fig. 2. An embodiment of the present invention provides a method for determining a scheduling manner of sorting equipment, as shown in fig. 3, the method includes the following steps.
S301: the line of symmetry is determined from the position information of the workstations in the warehouse.
The distribution of the workstations in the warehouse is determined according to the position information of the workstations, and then the symmetry line can be determined. As can be seen from fig. 2, the workstations are located on opposite sides of the warehouse, and the symmetry line can be determined as shown in fig. 2.
S302: the workstations are divided into a first group of workstations and a second group of workstations based on a symmetry line.
The two working stations are divided into two groups based on the symmetry line, that is, the two working station groups located at the two sides of the symmetry line are respectively a first working station group and a second working station group.
S303: and determining the division ratio according to the number of the workstations respectively included in the first workstation group and the second workstation group.
After the work stations are divided into the work station groups, the sorting equipment serving each work station group is determined by taking the work station group as a unit. In order to avoid the sorting equipment from being concentrated on one or more work stations, the sorting equipment is divided according to the number of the work stations in the work station group, so that the dispatching balance of the sorting equipment is ensured. In the scenario shown in fig. 2, where the first station group includes 2 stations and the second station group includes 3 stations, the division ratio may be the ratio of the number of stations included in the first station group to the number of stations included in the first station group, i.e. the division ratio is equal to 2: 3.
It should be noted that, in some scenarios, a warehouse may be provided with a plurality of workstations, but not all workstations are in an on state, that is, some workstations are off and do not work for a period of time, for a workstation that does not work, there is no need to consider article sorting and sorting equipment allocation, and all workstations involved in the embodiments of the present invention are all workstations that are in an on state and need sorting equipment to sort articles.
S304: and determining the coordinates of the sorting equipment in the warehouse in the working state based on the symmetry line.
In this step, the coordinates of the sorting devices in operation are determined in order to determine the distribution of the sorting devices in operation, and then the sorting devices are assigned. Since the work stations are divided from the symmetry line, the distribution of the sorting equipment in working state can be determined by taking the symmetry line as a reference, so that the coordinates of the sorting equipment in working state in the warehouse are determined based on the symmetry line in the step.
Specifically, after the symmetry line is determined, the symmetry line can be taken as an X axis in the step, and then the direction perpendicular to the symmetry line is taken as a Y axis, so that after the coordinate axis is determined, the coordinate of each sorting device in the working state is determined by taking the coordinate axis as a reference. The sorting devices can be divided on the basis of the determined coordinates of the sorting devices in each operating state.
The sorting equipment in the working state may include sorting equipment in a transportation state, sorting equipment in a ranking state, sorting equipment in a return-to-work state, and the like, that is, sorting equipment which removes an offline, a charging, and the like and does not sort articles any more may be used as the sorting equipment in the working state.
S305: the dividing line is determined based on the coordinates and the division ratio.
The step of determining the parting line is to determine the parting line, the parting line is used for dividing the sorting equipment in the working state in the warehouse, and the determination mode of the parting line is not limited. In the embodiment of the invention, in order to simplify the determination mode of the dividing line, the dividing line is arranged to be parallel to the symmetrical line, so that the coordinate of the dividing line in the direction vertical to the symmetrical line is only required to be determined.
In the embodiment of the invention, the dividing line only needs to determine the coordinate of the dividing line in the direction of the vertical symmetry line, and can be determined based on the coordinate and the division ratio of the sorting equipment in a working state in the direction of the vertical symmetry line.
In the embodiment of the present invention, in step S305, the coordinates of the sorting apparatus in the working state may be determined by taking the symmetry line as the X axis, and further taking the direction perpendicular to the symmetry line as the Y axis. In this step, the coordinates of the sorting devices in the working state on the Y axis can be determined based on the coordinates of the sorting devices in the working state to obtain a coordinate set, then the coordinates in the coordinate set are sorted from small to large, and the coordinates of the dividing line in the direction perpendicular to the symmetry line are determined based on the division ratio, so that the dividing line can be determined.
For example, in the embodiment of the present invention, it is assumed that there are 5 sorting apparatuses in the transportation state, the coordinates of the Y axis of the destination are (1005, 1009, 1018, 1010, 1021), there are 10 sorting apparatuses in the queuing state including 4 sorting apparatuses on the left side and 6 sorting apparatuses on the right side, and the coordinates of the Y axis of the 10 sorting apparatuses are (1002, 1002, 1002, 1002, 1100, 1100, 1100, 1100) (the coordinate values of the sorting apparatuses queued at each station are the same). Then, a total of 15 sorting apparatuses in operation in the warehouse at this time result in a set of coordinates of the sorted Y-axis (1002, 1002, 1002, 1002, 1005, 1009, 1010, 1018, 1021, 1100, 1100, 1100, 1100). Because the sorting equipment with small coordinate values is close to the first workstation group, the sorting equipment with large coordinate values is close to the second workstation group, and the division ratio is 2:3, namely the ratio of the number of the sorting equipment serving the first workstation group to the number of the sorting equipment serving the second workstation group is 2:3, the sorting equipment with small coordinate values can be distributed to serve the first workstation group, and the sorting equipment with large coordinate values can be distributed to serve the second workstation group, therefore, the sorting equipment with small coordinate values can be divided according to the sorted coordinate set according to the ratio of 2:3, so that the ratio of the number with small coordinate values to the number with large coordinate values is 2:3, and the dividing point is the 6 th coordinate value, namely 1009, and at this time, the coordinate of the dividing line in the vertical symmetry line direction can be determined to be 1009.
In the above example, when the coordinates of the dividing line in the direction perpendicular to the symmetry line are determined according to the division ratio and are not exactly the coordinates in the set, the closest coordinates in the set may be determined as the boundary point. In addition, the dividing line is determined by taking the coordinate in the direction perpendicular to the symmetry line as 1009, and sorting equipment exists on the dividing line obtained in the way, so that in order to avoid the situation, after the coordinate in the direction perpendicular to the symmetry line of the dividing line is determined, the left side can be adjusted, for example, the determined coordinate is increased or decreased by a preset value, and the size of the preset value can be 1, or can be set by the user. In order to ensure that the sorting equipment is distributed according to the division ratio, the adjustment mode that the division ratio of the sorting equipment is closest to the division ratio determined in the step S303 after the division line is determined based on the adjustment of the direction coordinate of the vertical symmetry line of the division line may be used as the adjustment mode of the direction coordinate of the vertical symmetry line of the final division line.
It should be noted that, for sorting equipment in a queue or returned to a queue, the coordinates are determined according to the position of the queued station, so as to avoid that the sorting equipment is determined to serve other stations and further needs to be moved.
S306: the warehouse is divided into a first area and a second area according to a dividing line.
After the parting line is determined, the warehouse can be divided into two areas based on the parting line, each area comprises a work group, the area comprising the first work station group can be determined as the first area, and the area comprising the second work station group can be determined as the second area.
S307: it is determined that a sorting device in the first zone serves a first group of sorting devices and a sorting device in the second zone serves a second group of sorting devices.
Since the dividing line is determined based on the coordinates of the sorting devices and the dividing ratio, the dividing line divides the sorting devices in the warehouse into two parts while determining the first area and the second area, namely, the sorting device located in the first area and the sorting device located in the second sorting area, it can be determined that the sorting device located in the first area serves the first sorting device group, and the sorting device located in the second area serves the second sorting device group.
It should be noted that, the method for determining the scheduling manner of the sorting equipment in the embodiment of the present invention may be periodically executed, so as to implement the adjustment of the scheduling manner of the sorting equipment according to the states of the workstations and the sorting equipment in the target area. A typical cycle time may be set to the time for the sorting equipment to sort an item once, such as 30 seconds or 50 seconds. After determining the sorting equipment serving each station group, the sorting equipment may be assigned with the most recent queue bit strategy for the stations in each station group to ultimately determine which sorting equipment ultimately serves which station. After the working station group served by each sorting device is determined in each period, when the request information of the sorting device is received in the period to request the next queuing working station, the scheduling center can determine the working station to be queued by the sorting device based on the result determined by the embodiment of the invention and by combining the strategies such as the most recent queuing position and the like.
