[ detailed description ] A
For better understanding of the technical solutions of the present invention, the following detailed descriptions of the embodiments of the present invention are provided with reference to the accompanying drawings.
Fig. 1 shows a flow chart of a power distribution data reverse transmission method according to an embodiment of the present invention.
As shown in fig. 1, a flow of a power distribution data reverse transmission method according to an embodiment of the present invention includes:
and 102, acquiring power distribution service data in the management information area.
And 104, selecting a target data scheduling strategy from a plurality of data scheduling strategies according to the scheduling strategy selection information, wherein the plurality of data scheduling strategies comprise a data priority transmission strategy, a data traffic monitoring transmission strategy and a data packaging transmission strategy.
For a large amount of power distribution service data in the management information area, any one of a data priority transmission strategy, a data flow monitoring transmission strategy and a data packing transmission strategy can be selected for storage position allocation and further ordered transmission, wherein the transmission refers to that the power distribution service data is distributed to a corresponding storage position and then sent to a production control area.
And 106, distributing the power distribution service data to storage positions corresponding to the data types.
Wherein the data types include: a first data type and a second data type, wherein the first data type comprises: a change of state real-time class and a real-time request/response class; the second data type includes: non-real-time request/response class, periodic profile class, and aperiodic temporal class.
And 108, determining the transmission priority of the power distribution service data of each storage position according to the target data scheduling strategy.
The data priority transmission strategy refers to the transmission of the power distribution service data from high priority to low priority of the power distribution service data, so that the data with higher priority, namely the data with stronger importance can be transmitted preferentially, and the service quality of the power distribution service is improved. The data flow monitoring transmission strategy refers to the preset type of data with the data volume reaching a preset value in a priority mode, so that the important preset type of data can be transmitted in a priority mode once the important preset type of data reaches the high data volume, and the high transmission efficiency of the important data is guaranteed. The data packaging transmission strategy refers to that data of a preset type are combined into a combined file for preferential transmission, and due to the fact that a large amount of remote signaling changes can occur in the abnormal operation mode of the power distribution network, the data messages are small, the number of frames is large, the retrieval file lock can be triggered ceaselessly in the reverse transmission process, and the triggering process can cause delay of data transmission, so that the data are combined into the combined file, the size of the data is increased, the triggering times of the retrieval file lock are greatly reduced, and the efficiency of data transmission is improved.
Since the power distribution service data of the first data type is real-time data, and the power distribution service data of the second data type is non-real-time data, the data of the predetermined type in the data traffic monitoring transmission policy and the data packing transmission policy is generally referred to as the power distribution service data of the first data type.
And step 110, sending the power distribution service data of each storage position to a production control area through a reverse isolation device according to the sequence from high transmission priority to low transmission priority.
The method specifically comprises the following steps: and selecting a target reverse isolation device for the power distribution service data of each storage position in the plurality of reverse isolation devices according to the number and the size of the files in each storage position and the working states and data transmission flow of the plurality of reverse isolation devices.
That is to say, not only can the transmission priority of the power distribution service data to be transmitted be controlled, but also the corresponding priority can be set according to the difference between the working state and the data transmission flow of the plurality of reverse isolation devices for transmitting the power distribution service data, so that for the reverse isolation devices in the normal working state, the lower the current data transmission flow is, the more idle the reverse isolation devices are, the stronger the capability of transmitting data is, and the higher the corresponding priority is, that is to say, the reverse isolation devices with the higher priority can be preferentially selected to transmit the power distribution service data with the higher transmission priority. Therefore, bidirectional selection of data transmission is realized, and the efficiency of data transmission is further improved.
Through above technical scheme, the promptness and the reliability that distribution service data carries out reverse transmission in management information district to production control district have been promoted, can take different data scheduling strategies to the condition of difference for distribution data transmission's flexibility strengthens greatly, simultaneously, reduces the number of times that triggers of retrieval file lock, has improved distribution data transmission's efficiency, and generally speaking makes distribution service's whole service level show the improvement, helps promoting user experience.
Fig. 2 shows a flow chart of a power distribution data reverse transmission method according to another embodiment of the present invention.
As shown in fig. 2, in the case that the target data scheduling policy is a data priority transmission policy, the process of the power distribution data reverse transmission method includes:
And step 206, distributing the power distribution service data to a storage position corresponding to the data type.
And 208, determining a corresponding transmission priority according to the data type of the power distribution service data.
And step 210, sending the power distribution service data of each storage position to a production control area through a reverse isolation device according to the sequence from high transmission priority to low transmission priority.
In any of the above and below embodiments, the five basic data types, i.e., the change-of-state real-time type, the real-time request/response type, the non-real-time request/response type, the periodic section type, and the non-periodic temporary type, are classified according to the real-time performance and reliability of data transmission from the management information area to the production control area by the distribution automation master station.
The state-to-real-time data mainly refers to data which are received by the management information area and affect the change of the running state of the power distribution network or real-time data defined according to service requirements, the data are required to be transmitted to the production management area in real time, the real-time performance is high, and the real-time response time of industrial specifications needs to be met.
The real-time request/response data mainly comprises a response result of the distribution automation service of the management information area after the management information area sends a request or the production control area sends a request, the real-time performance is high, and the real-time response time of the industry standard needs to be met.
The non-real-time request/response data mainly comprises the response result of the distribution automation service of the management information area after the request is sent by the management information area or the request is sent by the production control area, but the data transmission can have delay or failure allowance, and after the failure or delay, prompt information can be provided or re-or continuous transmission can be adopted
The fixed-period section data mainly comprises fixed-period telemetering section data, and the data transmission can be delayed or not transmitted when the data flow exceeds a preset value, namely, the data transmission can be carried out only in idle time so as not to influence the transmission performance of the variable-real-time data and the real-time request/response data.
The transmission of the aperiodic temporary-like data is generally triggered by the initiation of a predetermined service or by the satisfaction of a predetermined condition by the predetermined service, which may be delayed or not transmitted when the data traffic exceeds a predetermined value.
Therefore, the priority of the variable-state real-time class, the real-time request/response class, the non-real-time request/response class, the fixed-period section class and the non-periodic temporary class can be set to be reduced in sequence, namely under the same condition, the data priority transmission strategy can be written into the corresponding storage positions in sequence from front to back according to the variable-state real-time class, the real-time request/response class, the non-real-time request/response class, the fixed-period section class and the non-periodic temporary class, and can also be sequentially sent to the production control area at the corresponding storage positions according to the sequence. Therefore, the real-time data can be transmitted preferentially, and the timeliness and the reliability of the transmission of the important data are ensured.
Fig. 3 shows a flow chart of a power distribution data reverse transmission method according to still another embodiment of the present invention.
As shown in fig. 3, in the case that the target data scheduling policy is a data traffic monitoring transmission policy, the process of the power distribution data reverse transmission method includes:
and step 302, acquiring power distribution service data in the management information area.
And step 304, selecting a data traffic monitoring transmission strategy from a plurality of data scheduling strategies according to the scheduling strategy selection information.
And step 306, distributing the power distribution service data to a storage position corresponding to the data type.
And 308, judging whether the data type of the power distribution service data is a first data type, if so, entering a step 310, otherwise, ending the process.
And 310, judging whether the data volume of the power distribution service data reaches a first preset value, if so, entering a step 312, and otherwise, ending the process.
In step 312, the data transmission speed in the second data type is reduced to a predetermined speed.
And step 314, preferentially transmitting the power distribution service data under the first data type.
That is, the data amount of the real-time class data of the first data type, i.e. the variable real-time class and the real-time request/response class, is considered preferentially, and if the data amount reaches the first predetermined value, it indicates that the data of the real-time class is overstocked and is easy to occur, so that the transmission speed of the data of the second data type of the non-real-time classes, such as the non-real-time request/response class, the periodic cross-section class and the non-periodic temporary class, can be reduced to ensure the transmission efficiency of the real-time class data. The transmission speed of the data of the second data type can be reduced to a preset speed, and the preset speed is greater than or equal to zero and is less than the transmission speed of the real-time data of the first data type.
Fig. 4 shows a flow chart of a power distribution data reverse transmission method according to another embodiment of the present invention.
As shown in fig. 4, in the case that the target data scheduling policy is a data packet transmission policy, the flow of the power distribution data reverse transmission method includes:
In step 410, it is determined whether the data size of the second combined file reaches a second predetermined value, and if yes, the process proceeds to step 412, and if no, the process proceeds to step 414.
