Description
Technical field
The present invention relates to power information acquisition technique field more particularly to a kind of communication tasks for supporting dynamic flow to control
Adaptive optimization dispatching method.
Background technique
As State Grid Corporation of China's power information acquisition system acquires the propulsion of construction object entirely, field erected acquisition is eventually
End quantity is gradually increased.Up to now, the total number of terminals that single provincial Utilities Electric Co. is accessed is already close to 3,000,000.Terminal
It is responsible for collecting information from intelligent electric energy meter and summarizing information uploading to main website, has in power information acquisition system very heavy
The effect wanted.
However, may cause the acquisition of scene operation due to upgrading excessively high frequency, equipment quality or management absence etc.
The parameter configuration of terminal has differences with the parameter that main website sidelights are recorded.It is abnormal and then possible that the difference of parameter may cause metering
Therefore the economic dispute in terms of the electricity charge, influences normal supply order and social equity.
To solve the problems, such as the parameter difference opposite sex, main website is needed to synchronize terminal parameter immediately, to avoid terminal parameter
Difference bring risk.But most of the intelligent electric energy meter quantity accessed in view of current each provincial company all alreadys exceed
10000000, data acquisition session is very heavy, and terminal parameter synchronizes communication resource contention is necessarily caused to be further exacerbated by, if
It is not controlled and dredges, it is equally possible to influence normal data acquisition order, reduce system running quality.
Summary of the invention
To overcome the above deficiencies, the invention provides one kind under the premise of not influencing terminal normal work,
Support the adaptive optimization adjustment of terminal parameter synchronous task, synchronous process is recorded, managed to terminal parameter, to mention
The communication task adaptive optimization dispatching method of the support dynamic flow control of the reliability of high terminal operating.
The present invention overcomes the technical solution used by its technical problem to be:
A kind of communication task adaptive optimization dispatching method for supporting dynamic flow to control, includes the following steps:
A) by server construction communication center agency service, it is responsible for receiving all terminal communication task requests；
B) communication requirement and currently believe that communication center agency service is constituted according to task type and task definition
All terminal communication tasks are divided into high priority and low priority by road resource provisioning situation；It is specific:
B-1 it) bears control instruction generic task and is divided into high-priority task, electric energy indicating value task is divided into low priority task；
B-2) nonelectrical energy indicating value generic task is divided into low priority task；
If it is determined that c) high-priority task, goes to and execute step h), spat and be determined as low priority task, and went to and hold
Row step d)；
D) communication center agency service periodically supervise in real time to the operating status of controllable priority query
It surveys, Testing index specifically includes that mission failure rate p1, mission requirements total amount p2, obstruction queue length change rate p3, level-one refers to
Mark weight vector p=(p1+p2+p3), two-level index weight vector index is q=(q in i-th first class indexi1+qi2,...,qim),
M is the number of the two-level index weight vector in first class index in formula；
E) pass through formulaIt calculates low priority task and executes control intensity
YACT, wherein piFor i-th of first class index weight, qijFor the weight of j-th of two-level index of i-th of first class index, xijFor qij
Assessed value；
F) pass through formula
Calculation basis task initial priority and service request
Arrival time dynamic evaluation task execution priority YDP, wherein YpFor task initial priority, TmaxWhen being executed for greatest requirements
Between, TAvgFor low priority task average performance times, Δ tiFor service request arrival time；
G) work as YDPWhen executing threshold value λ more than or equal to high priority, the low priority task waited for a long time is upgraded to high preferential
Grade；
H) task is executed using high-priority queue.
The beneficial effects of the present invention are: the communication task adaptive optimization dispatching method controlled by this support dynamic flow
Under the premise of not influencing terminal normal work, the adaptive optimization adjustment of the remote synchronization of terminal parameter can be realized.Due to
Dynamic flow control during task, can realize the synchronous high real-time of power information acquisition system data parameters and
Under the premise of high reliability, it is effectively reduced the pressure of power information capturing service application system communication channel operation.By " cutting
The mode of peak load ", dynamic adjust persistence strategy, guarantee communication channel safety and stability in pressure spikes phase control communication flows
Operation increases the complete and high efficiency of transmission that communication flows guarantees parameter in pressure trough period.By to task execution hierarchical policy,
High-priority task is effectively guaranteed real-time, highly reliable to be performed using the height of the limited communication resource.It realizes to task
Priority level and service request arrival time carry out jointed dispatch, effectively avoid continuous cross of low priority task for a long time can not
The problem of obtaining channel.
Specific embodiment
The present invention will be further described below.
A kind of communication task adaptive optimization dispatching method for supporting dynamic flow to control, includes the following steps:
A) by server construction communication center agency service, it is responsible for receiving all terminal communication task requests；
B) communication requirement and currently believe that communication center agency service is constituted according to task type and task definition
All terminal communication tasks are divided into high priority and low priority by road resource provisioning situation；It is specific:
B-1 it) bears control instruction generic task and is divided into high-priority task, electric energy indicating value task is divided into low priority task；
B-2) nonelectrical energy indicating value generic task is divided into low priority task；
If it is determined that c) high-priority task, go to and execute step h), if it is decided that is low priority task, goes to and hold
Row step d)；
D) communication center agency service periodically supervise in real time to the operating status of controllable priority query
It surveys, Testing index specifically includes that mission failure rate p1, mission requirements total amount p2, obstruction queue length change rate p3, level-one refers to
