In the cross-floor scheduling task, in order to improve the logistics efficiency, the elevator unit can be a double-door elevator; however, it can be understood that the double-door elevator has the characteristic of opening doors toward two opposite sides and forming a passage, and at this time, when the elevator unit is not in a certain floor, the intelligent mobile robot in the floor risks falling from the notch of the elevator unit when the same floor scheduling task is executed.
Based on the above situation, an embodiment of the present application provides a scheduling method for an intelligent mobile robot, where the scheduling method is applied to a robot control system, and please refer to fig. 2 to 4, the scheduling method for an intelligent mobile robot includes:
s1, when a same-layer scheduling task is executed, determining a current coordinate 11 of a target intelligent mobile robot 1 and a task coordinate 12 of the same-layer scheduling task; the target intelligent mobile robot 1 is an intelligent mobile robot that is selected at a layer where the same-layer scheduling task is located and executes the same-layer scheduling task.
As can be understood from fig. 3, the same-level scheduling task may be a scheduling task at a certain level of the stereoscopic shelving, for example, moving goods from a certain storage location at the M level to another storage location at the M level.
Alternatively, it can be understood that, in combination with the above-mentioned timing diagram of the cross-layer scheduling task in fig. 1 and fig. 4, the cross-layer scheduling task may also be divided into two scheduling sub-tasks of different layers, for example, the above-mentioned cargo cross-layer scheduling task may be divided into a scheduling sub-task of M layers (which is moved from the first storage location to the waiting point of the hoist unit first and then from the waiting point to a specific point in the hoist unit) and a scheduling sub-task of N layers (which is moved from the specific point in the hoist unit to the resource release point of the hoist unit first and then from the resource release point to the second storage location), so that, according to actual needs, the scheduling task of the same layer in this embodiment may also be a scheduling sub-task of a different layer of the cross-layer scheduling task.
The layer where the same-layer scheduling task is located can be provided with a plurality of intelligent mobile robots, and the target intelligent mobile robot is an intelligent mobile robot which is selected from the plurality of intelligent mobile robots and is used for executing the same-layer scheduling task; the selection criterion placed on the target intelligent mobile robot may be selected by an algorithm according to a task balancing principle or a distance nearest principle, for example, which is not limited in this embodiment.
S2, planning an avoidance path 4 from the current coordinate 11 to the task coordinate 12 and avoiding the avoidance area 3 according to pre-stored map information; the map information comprises avoidance coordinates 13 of an elevator unit on a layer where the same layer scheduling task is located, the avoidance coordinates 13 form an avoidance area 3, and the elevator unit comprises a double-door elevator.
The map information is pre-stored in the robot control system, the map information comprises avoidance coordinates of a hoisting machine unit on a layer where the same-layer scheduling task is located, and the avoidance coordinates form an avoidance area, namely the avoidance area represents a position area of the hoisting machine unit on the layer; the avoidance path is a path from the current coordinate to the task coordinate, and the path avoids an avoidance area of the hoisting machine unit; in other words, the evasive path avoids double-door elevator units.
S3, driving the target intelligent mobile robot 1 to move from the current coordinate 11 to the task coordinate 12 according to the avoidance path 4, so as to prevent the target intelligent mobile robot from falling from a lifting notch corresponding to the avoidance area; the lifting gap is used for lifting the lifting machine unit between different floors.
Wherein, can understand, target intelligent mobile robot can avoid two lifting machine units that open the door when moving along this route of evading to avoid dropping.
S4, receiving a scheduling instruction comprising the crossing path, or planning the crossing path under the condition that the evasive path cannot be obtained; the crossing path is a path from the current coordinate to the task coordinate, the crossing path crosses the avoidance area where the elevator unit is located along the direction of double doors of the elevator unit, and the planned crossing path aims at the minimum number of the avoidance areas where the elevator unit is located.
As shown in fig. 5 and fig. 6, one or more paths are inevitably formed from the current coordinates to the task coordinates, and the one or more paths cannot avoid the avoidance area 3, that is, the double-door elevator unit 2; then, a traversing path from the current coordinate to the task coordinate is planned, specifically referring to fig. 6, the traversing path traverses the avoidance areas of the elevator units along the direction of double doors of the elevator units, and when there are a plurality of selectable paths, the traversing path should select one of the avoidance areas traversing the elevator units with the least number.
That is, in order to drive the target intelligent mobile robot to move from the current coordinate to the task coordinate to complete the scheduling task at the same layer, if the evasive path cannot be obtained, the traversing path that traverses the elevator units with the least number may be selected, and in order to ensure that the elevator units are traversed, the traversing path should traverse the elevator units in the direction of double doors of the elevator units.
Of course, the traversing path may also be a designated path included in a scheduling instruction issued by an upper layer; that is, the traversing path may also be a designated path that must traverse the twin door elevator unit.
Therefore, the map information also includes the orientation information of the double doors of the elevator unit on the layer where the scheduling information of the same layer is located.
S5, sending an elevator application instruction to the task management system, so that the task management system sends an elevator occupation instruction to the equipment control system according to the elevator application instruction, and the equipment control system dispatches all elevator units related to the elevator occupation instruction to a layer where a same-layer dispatching task is located; the elevator application instruction and the elevator occupation instruction comprise all the elevator units corresponding to the avoidance area crossed by the crossing path.
And S6, under the condition that a confirmation instruction that all the elevator units 2 corresponding to the avoidance area 3 crossed by the crossing path 5 reach the layer where the same-layer scheduling task is located is obtained, driving the target intelligent mobile robot 1 to move from the current coordinate 11 to the task coordinate 12 according to the crossing path 5.
After the traversing path is planned or obtained, the robot control system firstly sends identification information of one or more hoisting machine units traversed by the traversing path to the task management system, and then the task management system occupies and dispatches one or more hoisting machine units to a layer where a same-layer dispatching task is located through the equipment control system; and the robot control system drives the target intelligent mobile robot to move according to the crossing path under the condition of obtaining a confirmation instruction that the one or more hoisting machine units all reach the layer where the same-layer scheduling task is located.
That is to say, when a crossing path is inevitably planned or obtained, the hoist units crossing the crossing path can be dispatched to the same layer, so that the double-door hoist units are taken as the path, and the target intelligent mobile robot is ensured to move from the current coordinate to the task coordinate to complete the task of dispatching the same layer; the same-layer scheduling task may include, for example, a shelf transportation task of the same layer, or the same-layer scheduling task may include a subtask of a cross-layer scheduling task, or the same-layer scheduling task may further include, for example, a charging task initiated by the intelligent mobile robot by itself.
And S7, under the condition that the driving target intelligent mobile robot 1 finishes traversing the path 5, traversing completion information is sent to the task management system, so that the task management system sends a hoist occupation removing instruction to the equipment control system according to the traversing completion information, wherein the hoist occupation removing instruction comprises all hoist units corresponding to an avoidance area traversed by the traversing path.
After the target intelligent mobile robot finishes traversing paths, the robot control system sends traversing completion information to the task management system, and after receiving the traversing completion information, the task management system sends a hoist occupation removing instruction to the equipment control system so as to remove occupation of one or more hoist units traversed by the traversing paths and schedule the one or more hoist units to other layers for operation.
Regarding the acquisition of the map information, the scheduling method further includes:
s01, sending a map information acquisition request to a task management system;
and S02, receiving and storing the map information sent by the task management system.
That is, for example, after the robot control system is started, the robot control system transmits a request for acquiring map information to the task management system, the task management system transmits the map information to the robot control system after assembling the map information, and the robot control system receives and stores the map information.
In one possible embodiment, the task coordinates include at least a first task coordinate 121 and a second task coordinate 122 arranged in a time sequence.
It should be understood that the two task coordinates are arranged in time sequence, that is, the target intelligent mobile robot reaches the first task coordinate from the current coordinate first, and then reaches the second task coordinate from the first task coordinate.
As described above with reference to fig. 7, the same-level scheduling task is, for example, a scheduling task of a certain level of the three-dimensional shelf, such as moving goods from the M1 storage location of the M level to the M2 storage location of the M level, then the first task coordinate is understood as the coordinate of the M1 storage location, and the second task coordinate is understood as the coordinate of the M2 storage location; or the same-floor scheduling task is a subtask of a cross-floor scheduling task, such as moving goods from an M1 storage position of M floors to an N2 storage position of N floors, the first task coordinate is understood to be the coordinate of the M1 storage position, and the second task coordinate is understood to be the coordinate of a waiting point of the elevator unit.
Then, referring now to fig. 7, step S2 may include:
s201, planning a multi-node avoidance path 41 that passes through the first task coordinate 121 and the second task coordinate 122 in order with the current coordinate 11 as a starting point and avoids the avoidance area 3, based on the map information.
The multi-node evasion path takes the current coordinate as a starting point and sequentially passes through the first task coordinate and the second task coordinate, wherein the node path between the current coordinate and the first task coordinate and the node path between the first task coordinate and the second task coordinate avoid the evasion area of the elevator unit.
Step S3 may include:
s301, according to the multi-node avoidance path 41, the driving target intelligent mobile robot 1 sequentially moves from the current coordinate 11 to the first task coordinate 121 and the second task coordinate 122 arranged in time series.
That is, the target intelligent mobile robot first moves from the current position to the position of the first task coordinate, acquires the goods shelf, then moves from the position of the first task coordinate to the position of the second task coordinate, and places the goods shelf or waits for the elevator unit.
Step S4 may include:
s401, receiving a scheduling instruction comprising a multi-node traversing path 51, or planning the multi-node traversing path under the condition that the multi-node evasion path 41 cannot be obtained; the multi-node crossing path is a path which takes the current coordinate 11 as a starting point and sequentially passes through the first task coordinate 121 and the second task coordinate 122, and the multi-node crossing path crosses the avoidance area 3 where the elevator unit is located along the direction of double doors of the elevator unit.
Similarly, with reference to fig. 8, for example, when at least one of the two node paths cannot avoid the hoist unit, a multi-node crossing path is obtained; or, the multi-node traversing path is a designated path included in a scheduling instruction issued by an upper layer.
Step S5 may include:
s501, under the condition that a confirmation instruction that all the elevator units corresponding to the avoidance area crossed by the multi-node crossing path reach the layer where the same-layer scheduling task is located is obtained, the target intelligent mobile robot is driven to sequentially move to a first task coordinate and a second task coordinate which are arranged according to a time sequence from the current coordinate according to the multi-node crossing path.
In a possible implementation manner, when the peer scheduling task is a subtask of the cross-peer scheduling task, that is, the task coordinate includes a specified waiting point coordinate of a specified hoisting machine unit of the peer scheduling task; the specified hoisting machine unit is a hoisting machine unit for executing the cross-floor scheduling task, and the specified waiting point coordinate is a coordinate of a waiting point beside the hoisting machine unit.
Furthermore, it should be understood that during the process that the target intelligent mobile robot moves from the current coordinates to the coordinates of the designated waiting point, the designated elevator unit may be set to be in a frozen state due to a fault, and at this time, the cross-floor scheduling task needs to be switched, namely, the elevator unit is replaced.
Then, referring to fig. 9 and 10, step S3 may include:
s31, receiving an updated coordinate 15 of the coordinate of the appointed waiting point sent by the task management system under the condition that the target intelligent mobile robot 1 does not arrive or arrives at the coordinate of the appointed waiting point;
when the target intelligent mobile robot does not reach the task coordinate (namely the designated waiting point coordinate) or reaches the task coordinate, the task management system receives the freezing information of the designated hoisting machine unit sent by the equipment control system, the task management system can select a new hoisting machine unit as an updated hoisting machine unit according to some preset ladder selection rules, correspondingly, the task coordinate in the scheduling task of the same layer is changed into the updated coordinate and sent to the robot control system, and the robot control system receives the updated coordinate sent by the task management system.
S32, acquiring a temporary coordinate 16 of the position of the target intelligent mobile robot 1;
it should be understood that the target intelligent mobile robot has moved at least a distance from the current coordinates and the robot control system should acquire temporary coordinates of the location where the target intelligent mobile robot is now located.
S33, planning an updated avoidance path 42 from the temporary coordinates 16 to the updated coordinates 15 and avoiding the avoidance area 3 according to the map information;
similarly, an updated avoidance path from the temporary coordinates to the updated coordinates is planned based on the map information acquired in advance, and the updated avoidance path also avoids the avoidance area of the elevator unit.
And S34, continuing to drive the target intelligent mobile robot 1 to move from the temporary coordinate 16 to the updated coordinate 15 according to the updated avoidance path 42.
And then according to the re-planned updated evaded path, the robot control system continuously drives the target intelligent mobile robot to move from the temporary coordinate to the updated coordinate.
Similarly, the re-planned path may be specified to traverse the hoist unit, or in the case that an updated avoidance path cannot be obtained when planning the path from the temporary coordinates to the updated coordinates, the step S3 may further include:
s35, receiving a scheduling instruction including an updating traversing path, or planning the updating traversing path under the condition that the updating avoiding path cannot be obtained; the updating traversing path is a path from the temporary coordinates to the updating coordinates, the updating traversing path traverses the avoidance areas where the elevator units are located along the double-door direction of the elevator units, and the planned updating traversing path aims at traversing the minimum number of the avoidance areas where the elevator units are located;
s36, sending a hoist application instruction to the task management system, so that the task management system sends a hoist occupation instruction to the equipment control system according to the hoist application instruction, and the equipment control system schedules all hoist units related to the hoist occupation instruction to a layer where a same-layer scheduling task is located; the method comprises the steps that an elevator application instruction and an elevator occupation instruction comprise all elevator units corresponding to an avoidance area through which a traversing path passes;
and S37, under the condition that a confirmation instruction that all the elevator units corresponding to the avoidance area crossed by the updated crossing path reach the layer where the same-layer scheduling task is located is obtained, driving the target intelligent mobile robot to move from the temporary coordinates to the updated coordinates according to the updated crossing path.
That is, the re-planned path is designated to traverse the hoist unit, or, in the case that the updated evasive path cannot be obtained, the robot control system needs to plan an updated traversing path from the temporary coordinates to the updated coordinates; and then, the robot control system continues to drive the target intelligent mobile robot to move from the temporary coordinate to the updated coordinate according to the updated traversing path.
It should be understood that the above-described updated avoidance path and updated traversal path may be acquired in a case where the target smart mobile robot has started from the current coordinates.
When the target intelligent mobile robot starts from the current coordinate, the task management system receives the freezing information of the appointed hoister unit, the task management system directly sends the updated scheduling task of the same layer to the robot control system, and the robot control system directly plans a path according to the updated scheduling task of the same layer.
In addition, when the specified hoisting machine unit is frozen, the elevator selection rule for reselecting the hoisting machine unit by the task management system can be determined according to actual needs, for example, the elevator selection rule can be combined with a special elevator rule or a task balancing rule, the special elevator rule is that a specific hoisting machine unit is selected according to different goods, and the task balancing rule is that each hoisting machine unit is sequentially selected according to a certain sequence of the hoisting machine units.
In the one possible implementation mode, the two lifting machine units that open the door still can hold in the palm two lifting machines more, promptly, be equipped with a plurality of positions of carrying cargo in the lifting machine unit, can promote a plurality of goods shelves simultaneously, this moment, this lifting machine unit should have a plurality of waiting points, also a plurality of waiting points correspond a plurality of positions of carrying cargo respectively, and like this, intelligent movement robot can get into the lifting machine unit from a plurality of different waiting points, and the goods shelves can be followed a plurality of positions of carrying cargo in the lifting machine unit and moved to a plurality of waiting points respectively, and logistics efficiency is improved.

s8, driving the target intelligent mobile robot to move to a cargo carrying position close to the unoccupied waiting point in the appointed elevator unit from the unoccupied waiting point; the designated elevator unit is provided with a plurality of loading positions, and the plurality of loading positions correspond to the plurality of waiting points respectively.
That is, after the target intelligent mobile robot is driven to move to the unoccupied waiting point of the designated elevator unit, the robot control system drives the target intelligent mobile robot to move into the designated elevator unit to be placed on a shelf or directly lifted by the designated elevator unit.
It will be appreciated that to ensure efficiency, the target intelligent mobile robot should move into the loading position of the designated elevator unit close to the unoccupied waiting point.
