Referring to fig. 1, in an embodiment, a database synchronization method based on power data is applied to a network isolation device, the method including:
101. when receiving database synchronization instructions for a plurality of power plant terminals, acquiring communication load capacity of a network isolation device;
in this embodiment, a plurality of power plants are provided in an external network (wide area network), each of which is provided with a corresponding power plant terminal, and the power plant may be at least one of a hydraulic power plant, a thermal power plant, a wind power plant, and a photovoltaic power plant. The intranet (local area network) is provided with a power plant production control large area, the production control large area refers to a safety area formed by a power monitoring system which has data acquisition and control functions and is longitudinally connected with a special network or a special channel, the power plant production control large area is provided with a power database, the power plant database is used for storing power data of each power plant, and the power data can comprise running state data, generating capacity data and the like of power equipment in each power plant. The network isolation device is a unidirectional isolation device, namely, each power plant terminal in the external network synchronizes power data to a power plant production control area in the internal network through the network isolation device so as to realize safe communication between the internal network and the external network.
In this embodiment, the database synchronization instruction for the plurality of power plant terminals may be actively initiated by a production control terminal in a power plant production control area in the intranet, or may be triggered at a fixed time, which is not limited herein.
In this embodiment, the communication load of the network isolation device refers to the communication data processing capability value that the network isolation device has used currently, and may also refer to the ratio of the communication data processing capability value that the network isolation device has used currently to the communication data processing maximum capability value of the network isolation device. For example, the communication load of the network isolation device may be at least one of a CPU occupancy rate, a memory occupancy rate, and a network bandwidth utilization rate of the network isolation device, and the communication load of the network isolation device may be further calculated from at least one of the CPU occupancy rate, the memory occupancy rate, and the network bandwidth utilization rate of the network isolation device, which is not limited herein.
102. When the communication load capacity is larger than the preset load capacity, acquiring the electric power data quantity to be synchronized in each power plant terminal and the power plant grade of the power plant where each power plant terminal is located;
in this embodiment, when the communication load capacity is greater than the preset load capacity, it is determined that the communication load of the network isolation device is greater, and data blocking may occur at the network isolation device, so that the electric power data amount to be synchronized in each power plant terminal and the power plant class of the power plant where each power plant terminal is located are obtained, so as to control the electric power data synchronization of the plurality of power plant terminals. And the power plant terminals are provided with corresponding electric power data to be synchronized. The refinement step of obtaining the amount of power data to be synchronized in the power plant terminal is detailed in the embodiment shown in fig. 3. The refinement step of obtaining the plant level of the plant where the plant terminal is located is detailed in the embodiment shown in fig. 4.
103. Determining a synchronization priority of each power plant terminal based on the power data amount and the power plant level;
in this embodiment, the synchronization priority of the power plant terminals, that is, the synchronization order of the power plant terminals, is positively correlated with the power data amount and the power plant level.
104. And the control network isolation device sequentially synchronizes the electric power data to be synchronized in each power plant terminal to an electric power database in a power plant production control large area according to the synchronization priority.
In this embodiment, the control network isolation device sequentially acquires power data to be synchronized from each power plant terminal according to the synchronization priority, and synchronizes to the power database in the power plant production control area, so as to avoid data blockage caused by simultaneous database synchronization of multiple power plants. The higher the synchronization priority is, the more the power plant terminals are synchronized with the power data.
In the technical scheme disclosed by the embodiment, when the communication load capacity of the network isolation device is large, the synchronization priority of each power plant terminal is determined based on the power data amount to be synchronized and the power plant grade, and the power data to be synchronized in each power plant terminal is synchronized according to the synchronization priority, so that the data blockage at the network isolation device is avoided, and the synchronization efficiency of the power data is improved.
In another embodiment, as shown in fig. 2, on the basis of the embodiment shown in fig. 1, 103 includes:
201. determining a first score corresponding to the amount of power data;
in some embodiments, determining a first score corresponding to the amount of power data may include: acquiring a plurality of historical power data volumes of the network isolation device in historical synchronization and the historical synchronization time consumption corresponding to each historical power data volume; determining a change relationship between the data amount and the synchronization time consumption based on the plurality of historical power data amounts and the historical synchronization time consumption corresponding to each historical power data amount; determining an expected synchronization time for the amount of power data based on a changing relationship between the amount of data and the synchronization time; the synchronization time consumption will be expected as the first score corresponding to the amount of power data. Wherein the first score is generally positively correlated with the amount of power data. The historical power data volume is the historical power data volume when the network isolation device synchronizes the power data of one power plant terminal in the historical period, and the historical power data volume when the power data of different power plant terminals in different historical periods are synchronized is recorded, so that the historical power data volumes can be obtained.
Because each power plant terminal in the external network and the power plant production control area in the internal network cannot be directly communicated, the network isolation device needs to adopt a freemaker technology, and the FTL template is utilized to generate corresponding data files for the power data to be synchronized, and then the data files are sent to the power plant production control area in the internal network, so that the synchronization of the power data is realized. The amount of the electric power data to be synchronized in the power plant terminal is generally large, the electric power data to be synchronized in the power plant terminal generally comprises a plurality of electric power data tables, and different electric power data tables have different table structures, main keys, table field attributes and other information, so that the time required for generating corresponding data files is different, namely the synchronization time consumption of different electric power data is also different, and therefore the expected synchronization time consumption of the electric power data amount can be predicted based on the change relation between the data amount and the synchronization time consumption. Wherein, freemaker is a template engine: i.e., a generic tool based on templates and data to be changed and used to generate output text (HTML web pages, email, configuration files, source code, etc.).
In some embodiments, determining a change relationship between the amount of data and the synchronization elapsed time based on the plurality of historical power data amounts and the historical synchronization elapsed time corresponding to each historical power data amount may include: taking each historical electric power data quantity as an abscissa, taking the historical synchronization time consumption corresponding to each historical electric power data quantity as an ordinate, and obtaining a plurality of coordinate points in a plane rectangular coordinate system; fitting a plurality of coordinate points in a plane rectangular coordinate system to obtain a change curve between the data volume and the synchronization time consumption, wherein the change curve records the change relation between the data volume and the synchronization time consumption. At present, a machine learning mode can also be adopted, taking a neural network model as an example, and a preset neural network model can be trained based on a plurality of historical electric power data amounts and historical synchronization time consumption corresponding to each historical electric power data amount as training samples, so that a model for predicting the synchronization time consumption is obtained, and the model for predicting the synchronization time consumption comprises a change relation between the data amount and the synchronization time consumption.
In some embodiments, determining an expected synchronization time for the amount of power data based on a changing relationship between the amount of data and the synchronization time may include: taking the electric power data quantity as an abscissa, and taking the numerical value of the electric power data quantity corresponding to the ordinate in the change curve as the expected synchronization time consumption of the electric power data quantity. Alternatively, determining the expected synchronization time for the amount of power data based on the changing relationship between the amount of data and the synchronization time may include: and inputting the electric power data quantity into the model for predicting the synchronization time consumption, and obtaining the expected synchronization time consumption output by the model for predicting the synchronization time consumption.
202. Determining a second score corresponding to the power plant level;
in this embodiment, the plant ranks may be generally categorized into primary, secondary, tertiary, etc., with different plant ranks corresponding to different second scores. In general, the second score is positively correlated to the plant class.
203. Taking the sum of the first score and the second score as the comprehensive score of the power plant terminal;
in this embodiment, each power plant terminal corresponds to a first score, a second score, and a composite score.
204. Sequencing the plurality of power plant terminals according to the comprehensive scores to obtain the ranks of the plurality of power plant terminals;
in this embodiment, among the ranks of the plurality of power plant endpoints, the higher the composite score, the higher the rank of the power plant endpoint.
205. Based on the ranking of the plurality of power plant endpoints, a synchronization priority for each power plant endpoint is determined.
In this embodiment, the higher the synchronization priority of the top ranked power plant terminals is, in general.
In some embodiments, at least two power plant terminals of the same synchronization priority may be present simultaneously among the plurality of power plant terminals. The control network isolation device sequentially synchronizes the power data to be synchronized in each power plant terminal to the power database in the power plant production control area according to the synchronization priority, and may include: and simultaneously synchronizing the power data to be synchronized of at least two power plant terminals with the same synchronization priority, so as to improve the synchronization efficiency of the power data to be synchronized in the plurality of power plant terminals. It can be understood that the synchronization of the power data may be limited not only by the data processing capability of the network isolation device, but also by the network bandwidth of each power plant terminal, so that the synchronization of the power data may be performed by at least two power plant terminals to be synchronized at the same time, so as to improve the synchronization efficiency of the power data, for example, when the network bandwidths of at least two power plant terminals with the same synchronization priority are smaller than the preset bandwidth, the synchronization of the power data to be synchronized by at least two power plant terminals with the same synchronization priority is performed at the same time.
In some embodiments, determining a synchronization priority for each power plant endpoint based on the ranks of the plurality of power plant endpoints may include: determining a remaining communication capacity of the network isolation device based on the communication capacity of the network isolation device; determining a target number of power plant terminals which can be synchronized simultaneously based on the remaining communication load, the target number being positively correlated with the remaining communication load; based on the target number, determining the synchronization priority of each power plant terminal in the ranking of the plurality of power plant terminals, wherein the total number of the plurality of power plant terminals with the same synchronization priority is the target number. Taking the target number as 2 as an example, determining the synchronization priority of each power plant terminal in the ranking of the plurality of power plant terminals based on the target number may include: the synchronization priority of both the first and second ranked power plant endpoints is set to the first level priority.
In the technical scheme disclosed by the embodiment, a first score corresponding to the electric power data amount is determined, a second score corresponding to the power plant grade is determined, the sum of the first score and the second score is used as the comprehensive score of the power plant terminals, and the plurality of power plant terminals are ranked according to the comprehensive score, so that more proper synchronous priorities of the plurality of power plant terminals are determined.
In yet another embodiment, as shown in fig. 3, based on the embodiment shown in any one of fig. 1 to 2, the obtaining, in step 102, the amount of power data to be synchronized in each power plant terminal includes:
301. acquiring the occupied storage capacity of the power data to be synchronized in each power plant terminal, and acquiring the number of power data tables included in the power data to be synchronized in each power plant terminal;
in this embodiment, by sending a query instruction of the power data to each power plant terminal, the occupied storage capacity of the power data to be synchronized and the number of the power data tables included in the power data to be synchronized, which are fed back by each power plant terminal, may be obtained. The power data to be synchronized is generally stored in a table form, that is, the power data to be synchronized includes a plurality of power data tables, and different power data tables may have different table structures, primary keys, table field attributes, and other information.
302. Determining a first score corresponding to the occupied storage capacity;
303. determining a second score corresponding to the number of the power data tables;
in this embodiment, the first score is inversely related to the occupied storage capacity and the second score is inversely related to the number of power data tables.
