Specific embodiment
The invention will be further described below.Following embodiment is only used for clearly illustrating technical side of the invention
Case, and not intended to limit the protection scope of the present invention.
The store management scheduling system of electric-power metering production of the invention is as shown in Figure 1, as can be seen from the figure storehouse pipe
Reason task management, storehouse scheduling and equipment control three levels composition, and task management is responsible for receiving that upper-level system issues goes out
Inbound task classifies inbound task out, refine to certain one kind and enters and leaves library operation flow；Storehouse scheduling enters and leaves according to specific
Library operation flow carries out dynamic setting to scheduling strategy, by dispatching algorithm, carries out the distribution of storehouse task and transmission line distribution；
Unified management storehouse hardware device is responsible in equipment control, and passes through interface and software systems interaction data.Specific implementation process is such as
Under:
1) task management
The purpose of store management scheduling is exactly to instruct assets to go out to be put in storage according to inbound task out, so the first step seeks to connect
The inbound task out that upper-level system issues is received, assets are gone out into inbound task and are specifically classified by business, including library proparea enters and leaves
Storage and seal storage out are examined and determine out in library, after receiving the inbound task out that upper-level system issues, are based on flowsheet simulation machine
System, will receive out inbound task according to specific business and further refine, and library proparea is such as gone out storage and is subdivided into FCL arrival
Equipment storage, empty van arrival storage and equipment dispatching delivery outbound, will examine and determine out storage be subdivided into calibration equipment return library, calibrating set
Standby outbound and calibrating empty van outbound, seal are gone out to be put in storage to be subdivided into seal equipment and return library, the outbound of seal equipment and seal empty van go out
Library, and the mission bit stream after refinement is saved in database, it dispatches and uses for storehouse.It can also be according to oneself production status
Inbound task is carried out out further to segment, by being decomposed to inbound task out, for storehouse scheduling calculate provide science according to
According to.
2) storehouse is dispatched
The core of store management scheduling is that flow scheduling calculates, real because store management storage is driving method in kind
During object flows on the transmission line, automatically controlled information can be reported automatically by reaching special platform, storage request slip be generated, so entering
The transport operation that library generates, can guarantee to be put in storage orderly progress, not will cause congestion, without being scheduled.Store management outbound
Transport operation needs timing to generate, if without scheduling, it will causes chaotic task execution, the congestion of storehouse transmission line or transmission
Line is vacant, these three situations all can cause production efficiency low, so it is scheduled control for storehouse outbound operation flow, it is fixed
Shi Shengcheng outbound transport operation just becomes very necessary.
Outbound transport operation timing create-rule use flow scheduling calculation method, including task allocation algorithm and
Two aspect of transmission line allocation algorithm.The factor of influence task distribution includes task priority and parallel outbound task number, is appointed
Business priority reflects the urgency level of task, and priority is high to be first carried out.By taking parallel task number is 2 as an example, if two are appointed
Priority of being engaged in is different, and priority is high to be first carried out；If two task priorities are identical, at this time two tasks will be in order
It executes, task allocation algorithm is as shown in Figure 2.
Figure it is seen that task allocation algorithm includes priority algorithm and task piece round-robin.For preferential
The different task of grade guarantees that the high outbound task of priority first carries out generation outbound transport operation using priority algorithm, if
Task priority is identical, using task piece round-robin, task is divided into operation segment, each task rotation, which executes, generates outbound
Transport operation.Three or three or more task allocation schedules and so on, it is preferential that user can set according to production needs task
Grade and parallel outbound task number carry out task dynamic allocation, flexibly control storehouse outbound.
Outbound transport operation is not unconfined generation, it is also necessary to be carried in conjunction with the control outbound of transmission line allocation algorithm
Operation generates rhythm, and the factor for influencing transmission line distribution includes: transmission line rate flow, transmission line maximum capacity, operation coefficient
With execution operation spacing frequency, operating room is executed every frequency calculation method are as follows:
R=μ ÷ V
Wherein, R is to execute operation spacing frequency, and μ is the operation coefficient for guaranteeing transmission line use ratio highest and operating normally,
V is transmission line rate flow,
Wherein, operation coefficient μ is fixed, if improve transmission line rate flow, need to reduce execute operating room every
Frequency R.Such as the operation coefficient μ of the transmission line of equipment dispatching delivery outbound is 10, transmission line rate flow is 1m/s, then calculates
Operation spacing frequency R=μ ÷ V=10 ÷ 1=10s is executed out, and will execute operation spacing frequency and be set as 10s will be optimal scheduling side
Case.
Assuming that transmission line maximum capacity is Qmax, it is currently executing operation number Qc, difference Qt, it may be assumed that
Qt=Qmax-Qc
If Qt=0, illustrate that transmission line is carrying out operation number Qc and has reached transmission line maximum capacity Qmax, at this time
Storehouse scheduling just stops generation outbound transport operation and is judged again, directly after the waiting time (executing operation spacing frequency R)
To Qt > 0, operation number is carrying out less than transmission line maximum capacity, outbound transport operation is just regenerated, could only in this way protect
Card transmission line use ratio maximizes.
After outbound transport operation generates, storehouse dispatch layer is assigned by web Service interface mode to equipment control layer
Instruction is carried, storehouse dispatch layer only need to assign transport operation to equipment control layer, it is not necessary to directly interact with hardware device itself, letter
Store management workload is changed.
Carry out task allocation schedule calculates and the calculating of transmission line allocation schedule needs to be scheduled tactful configuration in advance.It is in office
Storehouse outbound task of the management level of being engaged in after refining include equipment dispatching delivery outbound, calibration equipment outbound, calibrating empty van outbound,
The outbound of seal equipment and seal empty van outbound are scheduled tactful configuration for each outbound task, including setting task is preferential
Grade, executes operation spacing frequency, transmission line rate flow and transmission line maximum capacity six at parallel outbound task number, operation coefficient
A parameter, and be saved in database, according to metering condition of production configuration parameter default value.
By taking outbound process is delivered in dispatching as an example, it is as follows to generate transport operation process: dispensing delivery firstly the need of setting equipment
The scheduling strategy configuration item of outbound, including setting task priority, parallel outbound task number, operation coefficient, execute operating room every
Frequency, transmission line rate flow and transmission line maximum capacity；Next needs opening timing to dispense library button of delivering out, guarantees that timing is appointed
Business executes；Finally, executing dispatching delivery outbound strategy, outbound task is delivered according to task priority in dispatching in execution
Carry out descending sort, take priority it is maximum that, if there is a plurality of, then (N=goes out N item dispatching outbound task parallel before taking
Library number of tasks), and execute dispatching delivery outbound transport operation when reaching and (executing operation spacing frequency) and generate.When in execution
Transport operation number be more than or equal to transmission line maximum capacity when, immediately stop outbound transport operation generate, wait (execute operating room every
Frequency) after the time, restart.To the dispatching outbound task for meeting execution condition, plan when having applied for that assets number is more than or equal to
When assets number, the dispatching outbound task will be skipped and carry out next task dispatching Delivery.Outbound transport operation content includes: to remove
Fortune the time started, carry the end time, need to carry outbound pile bar code, carry source address (when outbound source address be storehouse storage space compile
Number), carry destination address, the affiliated receipt lot number of assets etc..
Other outbound process transport operation generating process are similar with dispatching outbound.
3) equipment controls
Metering production storehouse hardware device includes that piler, elevator, shuttle, radio frequency door, control panel and conveying are set
It is standby, in store management scheduling, hardware device is uniformly controlled by equipment control layer, storehouse dispatch layer only need to be to equipment
Control layer assigns transport operation, it is not necessary to directly interact with hardware device ontology, simplify store management workload.Guarantee library simultaneously
When real estate management manages system reform upgrading, without carrying out hardware debugging again, debug time is saved, ensure that software systems and hardware
The independence of equipment.
The present invention is isolated storehouse dispatch layer and hardware device by web Service interface mode.Storehouse scheduling
Interface between layer and equipment control layer uses semiduplex mode, and storehouse dispatch layer receives the automatically controlled letter that equipment control layer reports
It after breath, is replied in time, new thread is then individually enabled and carries out flow scheduling calculating, generates transport operation, then again
Calling interface will generate result notice equipment control layer, and equipment control layer receives the transport operation that storehouse dispatch layer issues, in time
It is replied, and issues carrying command to each hardware device, process flow is as shown in Figure 3.
This semiduplex mode can reduce the equipment control layer waiting time, and equipment control layer receives management level reply and connects
After receiving successful information, it can continue to go to next node, it is not necessary to wait management level processing result, in addition this interface processing side
Formula can also reduce the probability that interface calls error, quickly improve the running efficiency of storehouse.
4) scheduling preview
Scheduling preview example referring to fig. 4, in order to further correct the scheduling strategy configuration parameter of storehouse dispatch layer, guarantees ginseng
Number in a reasonable interval, the present invention in joined scheduling preview function, scheduling preview include flow path match, scheduling calculating and
Three steps of job execution, wherein flow path match refers to be obtained according to specific business after refinement is decomposed from task management layer
Task, matching task process；Matching task process refer in the task according to acquisition go out storage type field, judge belonging to
It is put in storage type out, being put in storage type out is to carry out type definition to the task after decomposition, if belonging to equipment dispatching delivery outbound, inspection
Locking equipment outbound, calibrating empty van outbound, the outbound of seal equipment or seal empty van outbound process, then need that dispatching algorithm is called to generate
Outbound transport operation.
Scheduling, which calculates, refers to that storehouse dispatch layer carries out the calculating of task allocation schedule and transmission line allocation schedule calculates, most throughout one's life
At outbound transport operation；Job execution namely executes carrying according to outbound transport operation.By analyzing preview result,
Scheduling policy configuration parameter is adjusted based on the analysis results.
By taking outbound is delivered in dispatching as an example, because dispatching in execution delivery outbound task can be dropped according to task priority
Sequence sequence, take priority it is maximum that, in scheduling preview, if we think control, to be performed simultaneously the same comparison urgent
Outbound task A, in strategy configuration, A task priority is adjusted to maximum by us, and parallel outbound task number is set as 1, transmission
Line maximum capacity is set as 10 piles, and the spacing frequency R for executing operation is set as 9 seconds, and the transmission line rate flow V that is averaged is set as
0.2 meter per second, according to formulaThe value that operation coefficient μ can be extrapolated is R*V=9*0.2=1.8, if at this time
Analysis is not as a result, it has been found that transmission line use ratio is also high, we can set smaller value for the spacing frequency R for executing operation, directly
Reach maximum throughput to storehouse, the value of the μ at this time extrapolated can be used as guaranteeing transmission line use ratio highest and normal fortune
Capable operation coefficient.
By taking seal equipment outbound as an example, task priority is equal, and parallel outbound task number is set as 3, a plurality of if it exists
The identical seal equipment outbound task of priority then executes first 3, and transmission line maximum capacity is set as 8 piles, executes between operation
It is set as 7 seconds every frequency R, the transmission line rate flow V that is averaged is set as 0.2 meter per second, according to formulaIt can calculate
The value of operation coefficient μ is R*V=7*0.2=1.4 out, if analysis at this time as a result, it has been found that transmission line the case where there are congestions, I
Can set bigger value for the spacing frequency R for executing operation, until storehouse seal outbound route congestion releases, operation is flat
Surely, the value of the μ at this time extrapolated can be used as the operation coefficient for guaranteeing transmission line use ratio highest and operating normally.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvement and deformations can also be made, these improvement and deformations
Also it should be regarded as protection scope of the present invention.
