DETAILED DESCRIPTION

[0074] As shown in Figure 2 , a structure schematic diagram of a concentrator provided by the embodiment one of the present application is provided.

[0075] The concentrator 2 includes but is not limited to a man-machine interaction device 21, a local communication device 22, a remote communication device 23, a terminal block device 24, and a debugging and maintenance device 25. It should be understood that the control mainboard device, as a control circuit mainboard arranged inside the concentrator 2, realizes the functions of control, monitoring, data processing, and communication of the device by integrating various electronic components and programs, and is not shown in the Figure 2 .

[0076] The man-machine interaction device 21 includes but is not limited to a liquid crystal screen 211 for displaying data information such as the running state information, meter reading data, control state, and communication information of the concentrator 2, and a button 212 for cooperating with the liquid crystal screen 211. The information display of the concentrator 2 through the liquid crystal screen 211 cooperates with the button 212 for inputting corresponding instructions to the concentrator 2, thereby realizing the man-machine interaction operation function.

Figure 2

[0079]

[0080]

[0081] In an optional embodiment, the concentrator 2 further includes a debugging and maintenance device 25 for debugging and system maintenance. In the embodiment of the present application, the debugging and maintenance device 25 includes, but is not limited to, an RS232 communication interface 252 for debugging and maintaining the concentrator 2, and a USB interface 251 for importing and exporting data files and having the function of upgrading the program of the concentrator 2.

[0082] It should be understood that the concentrator mainly uses real-time acquisition and timing automatic acquisition to acquire power data. In the real-time acquisition process, the concentrator directly acquires corresponding data of the target device, or acquires various types of power data, parameters, and event data stored by the collector. In the timing automatic acquisition process, the concentrator automatically acquires data of the collector or the power meter according to the meter reading scheme set by the master station (for example, periodic acquisition with a preset 1-minute meter reading interval). The data acquired by the concentrator includes, but is not limited to, voltage, current, and power.

[0083] ​The power data acquisition process of the concentrator in the embodiment of the present application will be described below in the form of automatic acquisition at a fixed time.

[0084] As shown in the flowchart of the power data acquisition process provided by the first embodiment of the present application. Figure 3 The power data acquisition process provided by the first embodiment of the present application comprises the following steps.

[0085] In step S31, the power data of the target device is acquired in real time.

[0086] The concentrator acquires the load and power data of the target device by collecting the digital electric meter, and calculates the related power data information. The power data includes but is not limited to active power, reactive power, power factor, active power, total reactive power, and power consumption monitoring state signal.

[0087] In step S32, it is judged whether the power data is complete according to the preset data monitoring mode.

[0088] The concentrator of the present application extracts the corresponding verification parameter from the mapping table between the preset data and the verification parameter according to the received power data. And according to the preset cyclic redundancy check verification algorithm, the verification parameter and the power data are subjected to in division operation, so as to obtain the first check value. At the same time, the concentrator obtains the second check value stored in the power data by decompressing the power data. By comparing the first check value with the second check value, the received power data is judged to be abnormal.

[0089] When the first check value matches the second check value, the power data is not tampered with or damaged in the transmission or storage process, so the data is complete; when the first check value does not match the second check value, the power data has a problem in the transmission or storage process, the data is incomplete or has been tampered with.

[0090] In step S33, when the power data is incomplete, the preset data type corresponding to the power data is determined according to the classification label of the power data.

[0091] Among them, the data type is divided into key data and non-key data according to the importance of the collected power data. Correspondingly, the target device identifies and labels the classification label of the received power data according to the preset data classification standard. Through the corresponding relationship between the classification label and the data type, the concentrator can judge the importance of the power data, so as to avoid the waste of resources for supplementing the non-key data.

[0092] In step S34, when the data type is the preset key data, the supplement strategy corresponding to the power data is determined according to the timeliness label of the power data.

[0093] The supplement strategy includes a real-time supplement strategy and a timing supplement strategy. The real-time supplement strategy is usually used to ensure the accuracy of the real-time operation data of the power system, so as to respond to system changes or fault alarms in time. The timing supplement strategy is usually used to supplement the historical data or statistical data which have no high time requirement, so as to reduce the burden of the system and improve the efficiency of data supplement. The time effectiveness label includes a strong time effectiveness label and a weak time effectiveness label. The target device marks the power data according to the time sensitivity of the power data after receiving the power data. The time sensitivity of the power data used for historical record and statistical analysis of the operation of the power system is low, and is marked with a weak time effectiveness label. The time sensitivity of the power data related to the real-time operation state of the power system (for example, real-time load data, fault alarm data) is high, and is marked with a strong time effectiveness label.

[0094] The concentrator matches the supplement strategy according to the time effectiveness label marked by the key power data. When the time effectiveness label of the power data is a strong time effectiveness label, the concentrator immediately triggers the real-time supplement strategy, and quickly executes step S35 to obtain the missing or incorrect data. When the time effectiveness label of the power data is a weak time effectiveness label, the concentrator adopts the timing supplement strategy to supplement the data within a predetermined time window. The time window is usually set according to the actual demand of the data and the performance of the system.

[0095] By implementing the supplement matching strategy, the concentrator can more efficiently process the data supplement requirements of different time effectiveness, improve the accuracy and efficiency of data supplement, and provide strong support for the stable operation of the power system.

[0096] In step S35, data supplement is performed according to the supplement strategy and the address information.

[0097] The power data includes the address information. After matching the supplement strategy for the missing data, the concentrator performs line searching according to the supplement strategy and the address information, and repeatedly obtains the power data of the corresponding time period.

[0098] After the supplement is completed, the system processes the supplement result, including data verification, storage and update, etc. At the same time, the system also feeds back and adjusts the supplement strategy according to the supplement result, so as to optimize the future supplement operation.

[0099] In an optional embodiment, after the data supplement, the method further includes:

[0100] According to the data monitoring mode, it is judged whether the supplemented power data is complete or not;

[0101] When the copied power data is complete, first power data and second power data before and after the time stamp of the power data are respectively acquired according to the time stamp of the power data;

[0102] Linear fitting is performed on the first power data and the second power data to acquire standard change trend data;

[0103] First change trend data and second change trend data are respectively acquired according to the copied power data and the first power data and the copied power data and the second power data;

[0104] The standard change trend data, the first change trend data and the second change trend data are compared;

[0105] When the standard change trend data, the first change trend data and the second change trend data match, the copied power data is stored according to a preset data storage mode;

[0106] When the standard change trend data, the first change trend data and the second change trend data do not match, data copying is performed according to the copying strategy and address information.

[0107] It should be understood that the power data collected by the target device is linear data when the power equipment is in a stable working state. The concentrator can collect real-time data and frozen data of the target device according to the configured collection task. Linear fitting is performed on the data of adjacent collection periods to form a historical curve and save it. According to the historical curve, the power consumption condition of the power equipment can be analyzed, and troubleshooting can be performed. Therefore, the change trend information between the data can be acquired through data fitting to verify whether the power data obtained by copying is correct.

[0108] When the power data after the re-reading is complete, the first power data (i.e., data before the timestamp) and the second power data (i.e., data after the timestamp) before and after the timestamp marked by the power data are obtained respectively, and the first power data and the second power data are processed using a linear fitting method to obtain standard change trend data. At the same time, the first change trend data is calculated according to the re-read power data and the first power data, and the second change trend data is calculated according to the re-read power data and the second power data. Finally, the standard change trend data is compared with the first and second change trend data. When the standard change trend data, the first change trend data and the second change trend data match, it means that the re-read power data follows the expected change trend, and the re-read power data is correct, and the re-read power data is stored according to the preset data storage mode; when the standard change trend data, the first change trend data and the second change trend data do not match, it means that the re-read power data does not follow the expected change trend, and the re-read power data may be abnormal or incorrect, and data re-reading needs to be performed according to the re-reading strategy and the address information.

[0109] In an optional embodiment, when the re-read power data is incomplete or the standard change trend data, the first change trend data and the second change trend data do not match, the method further comprises:

[0110] Recording the number of re-reading execution of the power data;

[0111] Re-reading data according to the re-reading strategy and the address information;

[0112] When the number of re-reading execution reaches a preset number threshold, an alarm is given according to a preset alarm mode.

[0113] For example, the concentrator fails to obtain the data of the smart meter all the time, and the number of failures recorded in the concentrator for the smart meter is increased by one each time the failure occurs. At the same time, the concentrator re-executes data re-reading according to the above-mentioned method. When the number of failures reaches 6, the concentrator generates an alarm information according to a preset information format, and sends the alarm information to the contact device reserved by the inspector to notify the inspector to perform manual re-reading and fault troubleshooting, wherein the alarm information includes the device number of the smart meter, the address information of the smart meter and the failed data information.

[0114] The application is applied to the technical field of power data acquisition, and power data of a target device is acquired in real time through a data acquisition device, so that the acquired power data is subjected to integrity checking according to a preset data monitoring mode, when incomplete power data is found, the data type is determined according to a classification label of the data to determine whether the data is preset key data, for the key data, the emergency degree of the data is determined according to a time effectiveness label, and according to the time effectiveness and importance degree of the key data, a corresponding re-copy strategy is formulated, and according to the re-copy strategy and address information, an automatic re-copy operation of the data is performed. The application can reasonably perform automatic re-copy allocation by differentiating different types and key degrees of data, thereby improving the processing efficiency of data anomalies and ensuring the timeliness and continuity of power data.
