Detailed Description
In order that the above objects, features and advantages of the present disclosure may be more clearly understood, aspects of the present disclosure will be further described below. It should be noted that the embodiments and features of the embodiments of the present disclosure may be combined with each other without conflict.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may be practiced in other ways than those described herein; it is to be understood that the embodiments disclosed in the specification are only a few embodiments of the present disclosure, and not all embodiments.
In the prior art, when the problem of deadlock of robot traffic control is solved, a method for replanning a path for a robot with deadlock is generally adopted, but under some extreme conditions, such as a special road, the replanning of the path still cannot solve the deadlock, or the replanning of the path may cause the robot to slow down the task execution rate. In order to solve the above problem, an embodiment of the present disclosure provides a scheduling method for a robot.
Fig. 1 is a flowchart illustrating a scheduling method for a robot according to an embodiment of the present disclosure, where the method may be performed by a scheduling apparatus for a robot, where the apparatus may be implemented by software and/or hardware, and may be generally integrated in an electronic device. As shown in fig. 1, the method includes:
and 101, acquiring robot operation data.
The robot may be a mobile robot capable of operating based on a planned path to complete a certain task, and the specific type of the robot is not limited in the embodiment of the present disclosure. The robot operation data refers to data related to the robot in an operation state, and in the embodiment of the disclosure, the robot operation data includes an occupied state of a station to be operated of each operation robot in the operation state, where the occupied state includes an occupied state and an unoccupied state, and the number of the operation robots is at least two. The station to be operated refers to the station to be next in the planned path of the operation robot. The occupied state may represent attribution of an occupation right to the path, the occupied state represents that a station in the path is already occupied by the robot, and the unoccupied state represents that a station in the path is not occupied by the robot.
In the embodiment of the present disclosure, path planning and scheduling control of a robot may be implemented by a robot scheduling system, for example, fig. 2 is a schematic structural diagram of the robot scheduling system provided in the embodiment of the present disclosure, where the robot scheduling system may include a path planning module and a traffic control module, the path planning module is configured to plan a walking path of the robot based on a task issued to obtain a planned path of the robot, and the traffic control module is configured to track and adjust the walking path of the robot and an occupation state of the path in real time according to the planned path, so as to achieve a purpose of orderly scheduling work of the robot.
And 102, if the deadlock state is determined to occur based on the robot operation data, determining target robots in the deadlock state, wherein the number of the target robots is at least two.
Deadlock is understood to be a phenomenon that when two or more robots are running, because of mutual contention of resources, a loop is generated or because of a blocking phenomenon caused by mutual communication, and if no external force acts, the robots cannot advance, and at this time, the system is called deadlock or the system is deadlock, and the processes which are always waiting for each other are called deadlock processes. That is, when two or more robots wait for each other to release path resources and cannot move continuously in the operation process, it is determined that a deadlock state occurs.
In the embodiment of the present disclosure, determining the occurrence of the deadlock state based on the robot operation data may include: and if the occupation states of the sites to be operated of the at least two robots are occupied states and the sites to be operated of the other side are occupied mutually, determining that a deadlock state occurs. If the to-be-operated stations of two or more than two operating robots are occupied and the to-be-operated stations of the two or more operating robots are mutually occupied to form a closed loop, the situation that no robot can move is indicated, and the deadlock state is determined to occur. For example, when the operation robot comprises A, B and C, if A occupies the station to be operated of B, B occupies the station to be operated of C, and C occupies the station to be operated of A, an occupation closed loop is formed, a deadlock state is determined to occur, and A, B and C are target robots in the deadlock state. For another example, when the operating robots are robots D and E which operate in opposite directions, if D occupies the station to be operated of E and E occupies the station to be operated of D, it is determined that a deadlock state occurs, and D and E are target robots in the deadlock state.
And 103, controlling the target robot to execute an avoidance operation to remove the deadlock state when the avoidance condition is met based on the standby planning path of the target robot and the preset deadlock path length.
The standby planned path refers to another different planned path which can reach the terminal point except the planned path value of the robot which is currently running, one robot can be provided with a plurality of standby planned paths, and the specific number is not limited. The deadlock path length may be a preset path length that does not affect the passing efficiency of the robot, that is, a limited deadlock recalculation path length, and when the planned path of the robot is greater than the deadlock path length, the passing efficiency of the robot may be affected, and an avoidance station needs to be determined again for avoidance. The specific value of the deadlock path length is not limited in the embodiment of the disclosure, and can be set according to the actual situation. Optionally, the deadlock path length may be determined based on a total aging requirement of a current map where the robot is located to execute a task, or may be determined based on an interactive resource limit consumed by the robot in operation.
In the embodiment of the present disclosure, determining that an avoidance condition is satisfied based on a standby planned path of a target robot and a preset deadlock path length may include: and if the target robots do not have the standby planning paths or if at least one target robot has the standby planning paths and the standby planning paths are all larger than the deadlock path length, determining that an avoidance condition is met. The avoidance condition is a condition that when the user is in a deadlock state and does not have a proper standby planning path for unlocking, unlocking is carried out through avoidance. When all the target robots do not have the standby planning paths, the avoidance condition can be determined to be met, or when the target robots have the standby planning paths which are all larger than the predetermined deadlock path length, the avoidance condition can also be determined to be met.
In the embodiment of the present disclosure, controlling the target robot to execute the avoidance operation to remove the deadlock state may include: determining an avoidance robot and a target avoidance station, wherein the avoidance robot is one of the target robots; and controlling the avoidance robot to run to the target avoidance station so as to remove the deadlock state. Specifically, any one target robot in a deadlock state is determined as an avoidance robot, and based on the current position, the target position, the current planned path of the avoidance robot and the planned paths of other target robots in the deadlock state except the avoidance robot, path resources waiting for each other are bypassed, a corresponding target avoidance station is determined, the avoidance robot is controlled to operate to the target avoidance station, and when other robots in the deadlock state can pass, the deadlock state is removed. The setting factors of the avoidance station can include at least one of the following factors: avoiding the current planned path of the avoidance robot, the approach principle, occupying less resources and the like, wherein when the station comprises an automatic door or an elevator, the occupied resources are more.
Optionally, determining an avoidance robot and a target avoidance station of the avoidance robot includes: determining an initial avoidance station of each target robot; and determining the target robot with the shortest path between the initial avoidance station and the current station as the avoidance robot, and determining the initial avoidance station of the avoidance robot as the target avoidance station. The initial avoidance station can be understood as an avoidance station preset for each target robot. In the embodiment of the disclosure, an initial avoidance site of each target robot can be obtained first, an avoidance path between the current site of each target robot and the corresponding initial avoidance site is determined, the target robot with the shortest avoidance path is determined as the avoidance robot, and the initial avoidance site of the avoidance robot is determined as the target avoidance site.
In the embodiment of the present disclosure, if it is determined that a deadlock state occurs based on the robot operation data, after determining the target robot in the deadlock state, the method may further include: and if at least one target robot has a target planning path, determining that the target robot does not meet an avoidance condition, and controlling the corresponding target robot to operate on the basis of the target planning path so as to remove the deadlock state, wherein the target planning path is a standby planning path which is less than or equal to the length of the deadlock path. Wherein the number of the target planning paths may be at least one. If at least one target robot has a standby planning path which is less than or equal to the length of the deadlock path, namely a target planning path, determining that an avoidance condition is not met, and controlling the corresponding target robot to operate based on the target planning path so as to relieve the deadlock state.
According to the scheduling scheme of the robot, the robot operation data are obtained; determining target robots in a deadlock state if it is determined that the deadlock state occurs based on the robot operation data, wherein the number of the target robots is at least two; and when the standby planning path based on the target robot and the preset deadlock path length are determined to meet the avoidance condition, controlling the target robot to execute avoidance operation to remove the deadlock state. By adopting the technical scheme, when a deadlock state inevitably occurs and the robot in the deadlock state determines that no appropriate standby planning path exists based on the length of the deadlock path in the process of dispatching the robot, an avoidance mechanism can be adopted to remove deadlock, so that the problem of time waste caused by continuous waiting in the prior art is avoided, and the efficiency of deadlock unlocking is improved.
