Footpath planning subsystem: many AGV trolley path planning refers in a static state or dynamic, simple or complicated running space, the mobile route from incipient state to dbjective state of how to work as robot searches one, and ensure robot in moving process can safely, without walking around all obstacles with touching.Due to the variety of mobile work robot environment, complexity and uncertainty, path planning problem is caused to have the features such as complexity, randomness, multiple constraint, multiple goal.Gordian technique under dynamic environment needed for AGVs path planning comprises environmental modeling, planing method, prediction collision prevention strategy and coordination strategy etc.
The path planning of AGV system more than one, exactly when system has new task to trigger, selects suitable AGV to finish the work with the shortest time; When multiple AGV runs simultaneously, to each AGV optimum path search, and the conflict adopting cooperation control mechanism anticipation system potential, thus reduce or avoid obstruction or the collision of system to greatest extent; And while the overall operation efficiency ensureing many AGV system, the conflict wait time of minimizing system, realizes overall system time of run optimization as far as possible.
When task is assigned, when determine according to the state of AGV, what place, by which dolly through any paths to be finished the work.Many AGVs path planning is dynamic.Carry out path planning and must consider other robot and global context.First can plan alone for each AGV the path that a nothing is touched, then avoid the path conflict between each robot by various coordination strategy.
For AGV dolly distributes the most rational running route.Such as: when the state of the AGV selected by task is load, if so have other idle and very near and lucky section, the place being engaged in arriving of leaving one's post is unobstructed again time, with regard to that AGV of prioritizing selection.The optimal route found now is optimal route this moment, and in dolly driving process, the traffic behavior in some section changes, and will adjust queue sequence in time, changes running route.For the situation having many routes to select, optimal route is not often optimum that in theory, but will be determined have vehicle to stop loading for a long time in such as route and then will avoid as far as possible, replace with other sections by actual road conditions.
For the traffic problems scheduling in driving process.Dispatching to comprise to the traffic problems occurred in AGV driving process and get rid of obstacle in driving process and fault, there is the situation (multiple stage AGV waits for mutually) of deadlock and provides the release method occurring deadlock in monitoring AGV.
(1) scheduling conflict.
AGV fault.Can artificial treatment.
Path of navigation lost efficacy.Can according to the change corrigendum system parameter of system AGV, path of navigation.
AGV conflict etc.In dolly driving process, the path conflict that main existence three kinds is dissimilar:
(2) node conflict.Two AGV arrive a certain node simultaneously, and travel direction is different separately, at the vehicle collision that this node occurs.Can take waiting strategy, the AGV making priority high takes the lead in passing through.
(3) conflict is pursued and attacked.Two AGV travel in the same way, but due to speed difference, continue to keep this state, a rear AGV will be caused at a time to collide with last AGV, and this type of conflict is pursues and attacks conflict.Can take waiting strategy, the AGV making priority high takes the lead in passing through.
(4) conflict in opposite directions.Two AGV travel in opposite directions, and because every paths only allows the AGV that passes through simultaneously, therefore two AGV can not pass through simultaneously, occur to conflict in opposite directions.Time window or unidirectional figure can be utilized to solve.
Resource scheduling system: resource scheduling system is the resource such as multiple task matching AGV dollies, shelf, execution time of task subsystem by communication system, needs the many-sided factor such as quantity, route, task priority will considering AGV.
(1) task scheduling
According to the demand that the task subsystem received sends, generate task, give task certain priority according to the urgent of task and significance level simultaneously.
First task priority is determined.Sudden real-time task has the highest priority, the priority of task arrangement that priority is high.The task of same priority, according to time priority principle, to the priority of task arrangement of preferential one-tenth.
By task type simple classification:
1. point-to-point portage.Priority is low.
2. AGV charging.Priority is lower than the priority of failure problems, and higher than common point-to-point carrying, AGV charges not in time and cannot normally run, and can affect the operating efficiency of whole system.During priority is.
3. task reallocation etc. during AGV fault.Priority the highest (this task is natively far away from other unappropriated tasks on the one hand, and process can affect the normal operation of other tasks not in time on the other hand).Priority is high.
When the order that need perform too much does not have idle AGV, these tasks temporarily should be stored in memory device by upper computer, then progressively complete in certain sequence, and the order that grade is high will preferentially perform.The position optimization vehicle of upper computer residing for the task of required execution and current AGV distributes or scheduling.
Vehicle and shelf scheduling:
Vehicle and shelf-space allocation be exactly carry out task, shelf mate with AGV three's.The AGV dolly suitable according to the condition selecting of vehicle and shelf and shelf are executed the task.Chosen AGV or the shelf performing certain task, state becomes task and arranges, and comprises performing and task that is that will perform.
The status information of AGV dolly has: 1. normal.Can receive an assignment.2. fault is had.Need first to solve fault.3. load is had.Need first to complete current task to go again to perform other new tasks.4. charging is needed.First charge, temporarily can not accept new task.5. charge etc.
Before task really starts to perform (AGV dolly also do not arrive task initial point before), AGV dolly can accept other subsystem feedacks and adjust.The matching relationship of task and AGV is once change, and the instruction that the instruction of tasks carrying and task are cancelled also will according to circumstances be assigned again.
