Description

Technical Field

[0001] The present invention belongs to the field of automation communication technology in the field of electric power system, and in particular relates to a real-time data segment processing encoding and decoding method for a phasor concentrator and electronic equipment. Background Art

[0002] With the development of PMU technology, it has become the norm to collect phasor data at important plants and send it to the main station through the phasor concentrator. In recent years, the scale of data points that the phasor concentrator needs to process and forward has gradually expanded, especially after the phasor concentrator is compatible with the broadband measurement data forwarding function, the data scale has increased more significantly, which makes the computational load of the phasor concentrator increasingly heavy.

[0003] At present, the processing of real-time data by the phasor concentrator is generally divided into two steps: 1) After receiving the real-time data frame from the collector, the real-time data frame is thoroughly decoded according to the data measurement point according to the configuration frame, and then saved to the data cache; 2) When forwarding real-time data to the master station, the corresponding measurement point data is read from the data cache according to the configuration frame sent by the master station, and then encoded into a real-time data frame and sent to the master station. At present, the frame rate of the phasor concentrator receiving and sending real-time data is generally 100 frames per second. When the data measurement points and master stations of the collector increase, this processing method requires complete decoding and encoding, which will significantly increase the computing load of the phasor concentrator. Summary of the invention

[0004] In order to improve the processing efficiency of real-time data encoding and decoding of a phasor concentrator, the present invention provides a segmented encoding and decoding method suitable for real-time data processing of a phasor concentrator.

[0005] In order to achieve the above object, according to one aspect of the present invention, a phasor concentrator real-time data segment processing encoding and decoding method is provided, comprising the following steps:

[0006] When the phasor concentrator communicates with the collector, it determines the state field decoding information and data block decoding information in the real-time data frame of the corresponding collector according to the configuration frame 1 of the collector;

[0007] When the phasor concentrator receives the real-time data frame transmitted by the collector, it decodes the status field data according to the status field decoding information and saves it to the real-time data buffer area, and copies the data block according to the data block decoding information and saves it to the real-time data buffer area;

[0008] When the phasor concentrator communicates with the master station, the validity of the configuration frame 2 sent by the master station is checked, and a data segment mapping information table is formed according to the check result;

[0009] After starting to transmit real-time data to the master station, the status field data and data blocks are obtained from the real-time data buffer area for processing to form a complete real-time data frame for uploading.

[0010] According to some embodiments, the status field decoding information in the real-time data frame includes the position offset and length information of the status field defined in the real-time data frame.

[0011] According to some embodiments, the data block in the real-time data frame includes a data block of any one or more fields of PHASORS, FREQ, DFREQ, ANALOG and DIGITAL defined in the real-time data frame format.

[0012] According to some embodiments, the data block decoding information in the real-time data frame includes position offset and length information of the data block in the real-time data frame.

[0013] According to some embodiments, the validity of the configuration frame 2 issued by the main station is verified, and a data segment mapping information table is formed according to the verification result, specifically: verifying whether the collector customized in the configuration frame 2 issued by the main station is valid, and if it is valid, a real-time data collector table is formed; according to the real-time data collector table, verifying one by one according to the collector whether the measurement point data customized in the configuration frame 2 issued by the main station is valid, and if it is valid, a data segment mapping information table is formed.

[0014] According to some embodiments, it further includes: dividing the data block in the corresponding collector real-time data frame into one or more data segments according to the configuration frame 2 sent by the master station.

[0015] According to some embodiments, the copying of the data block and saving it to the real-time data cache area according to the data block decoding information is specifically as follows: obtaining the data block cache of the corresponding collector real-time data frame according to the position offset and length information of the data block in the real-time data frame in the data block decoding information, and saving the copy of the data block to the real-time data cache area.

[0016] According to some embodiments, the checking whether the collector customized in the configuration frame 2 sent by the master station is valid is specifically: checking whether the collector customized in the configuration frame 2 exists in the configuration frame 1 of the phasor concentrator.

[0017] According to some embodiments, the collector-by-collector verification of whether the customized measurement point data in the configuration frame 2 sent from the master station is valid is specifically: the collector-by-collector verification of whether the measurement point data in the configuration frame 2 exists in the corresponding collector in the configuration frame 1 of the phasor concentrator.

[0018] According to some embodiments, the data segment mapping information table includes position offset and length information of data blocks in the real-time data frame of the corresponding collector.

[0019] According to some embodiments, after the real-time data transmission to the main station is initiated, the status field and data block are obtained from the real-time data cache area for processing, specifically: the status field obtained from the real-time data cache area is corrected and encoded, and the data block obtained from the real-time data cache area is segmented and copied according to the data segment mapping information table.

[0020] According to some embodiments, according to the configuration frame 2 information sent by the master station, the data block in the corresponding collector real-time data frame is divided into one or more data segments, specifically: whether the collector measurement point data customized in the configuration frame 2 sent by the master station is determined to be continuous, if it is determined to be continuous, the data block is divided into one data segment; if it is determined to be discontinuous, the data block is divided into multiple data segments.

[0021] According to another aspect of the present invention, the present invention provides an electronic device, comprising a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein when the processor executes the computer program, the phasor concentrator real-time data segmentation processing and decoding method as described above is implemented.

[0022] The beneficial effects achieved by the present invention are as follows: after adopting the technical solution of the present invention, the phasor concentrator only needs to perform a small amount of decoding to complete the caching processing of the real-time data after receiving the real-time data from the collector, thus avoiding the complete decoding of the real-time data frame; and when transmitting and sending the real-time data to the main station, it only needs to copy the memory according to the data block, thus avoiding the search and encoding process according to the data measurement point, and effectively improving the parsing and encoding and decoding efficiency of the real-time data processing of the phasor concentrator.
