[0023] Furthermore, in step D, the data cleaning improves the quality of the collected data according to the steps of data review, missing value processing, outlier processing, data consistency check, and data verification; the data storage is to store the cleaned data into a database in the storage module.

[0024] Further,

[0025] The machine learning diagnostic steps in step E include:

[0026] EA. Determine the measuring point data to be diagnosed through the LCD display settings, and mark the associated measuring point data that affects the numerical value of the measuring point data to be diagnosed;

The edge computing module reads the database data in the storage module to obtain the historical data of the measurement point A to be diagnosed and the associated measurement points B and C, and determines the reference value of the measurement point A to be diagnosed under the corresponding numerical conditions of each associated measurement point.

[0059] Example 2

[0060] like Figure 2 As shown, the automatic adaptation and fusion method of power plant data specifications based on machine learning includes the following steps:

[0061] A. Use the LCD display to configure information functions, respectively configure the network attribute parameters of the fusion device and the external data source device, the network attribute parameters include: IP address, subnet mask, gateway and DNS server address, etc.;

[0062] B. The fusion device and the external data source device automatically perform a network communication test by sending a network connection program command, and the network connection program command includes an ICMP Echo request message command;

[0063] C. If the network communication is normal, the parameter information of the measurement point configuration file is automatically parsed, and the data protocol communication parameters are called from the parameter configuration database for automatic adaptation; if the network communication is abnormal, return to step A;

[0064] D. Clean and store the collected data;

[0065] E. Perform machine learning diagnosis on the selected data and forward the result data after diagnosis.

[0066] In step D, the data cleaning improves the quality of the collected data according to the steps of data review, missing value processing, outlier processing, data consistency check, and data verification; the data storage is to store the cleaned data into a database in the storage module.

[0067] The machine learning diagnostic steps in step E include:

[0068] EA. Determine the measuring point data to be diagnosed through the LCD display settings, and mark the associated measuring point data that affects the numerical value of the measuring point data to be diagnosed;

[0069] EB. Read the database data in the storage module to obtain the historical data of the measurement point to be diagnosed and the associated measurement points, and determine the reference value of the data of the measurement point to be diagnosed under the corresponding numerical conditions of each associated measurement point;

[0070] EC. Compare the current value of the data at the measurement point to be diagnosed with the reference value under the current working condition, determine whether the data value of the measurement point to be diagnosed is abnormal, and forward the diagnosis result data.

[0071] Step E is specifically as follows:

[0072] Perform machine learning diagnosis on the measurement point A to be diagnosed. The associated data B and the associated data C are the associated data of the measurement point A to be diagnosed. The values ​​of the associated data B and the associated data C will affect the value of the measurement point A to be diagnosed. The data value (A, B, C) at this moment is regarded as a working condition.

[0073] The measurement point A to be diagnosed is determined by the LCD display setting, and the associated data B and associated data C associated with the measurement point A to be diagnosed are selected. The edge computing module reads the database data in the storage module to obtain the historical data of the measurement point A to be diagnosed and the associated measurement points B and C, and determines the reference value of the measurement point A to be diagnosed under the corresponding numerical conditions of each associated measurement point. The steps for determining the reference value are as follows:

[0074] Set the threshold ε, the values ​​of the diagnostic point A under three typical working conditions are A1, A2, and A3, and the corresponding values ​​of the associated data B and associated data C are (B1, C1), (B2, C2), and (B3, C3).

Take 100 times, and we have (A1 1 , A1 2 , A1 3 , ..., A1 99 , A1 100 ), (A2 1 , A2 2 , A2 3 , ..., A2 99 , A2 100 ), (A3 1 , A3 2 , A3 3 , ..., A3 99 , A3 100 ), then its average The following are the benchmark values ​​of the test point A to be diagnosed under three typical working conditions:

[0075] ;

[0076] Compare the current value of the data at the point to be diagnosed with the reference value under the current working condition and set the threshold , that is, when the current associated data B and associated data C values ​​are within the range of (B1-ε≤B≤B1+ε, C1-ε≤C≤C1+ε), (B2-ε≤B≤B2+ε, C2-ε≤C≤C2+ε), (B3-ε≤B≤B3+ε, C3-ε≤C≤C3+ε), if the current value of the measurement point A to be diagnosed exceeds , , range, it means that under the three typical working conditions, the A value of the measurement point to be diagnosed is abnormal, and the current A value of the measurement point to be diagnosed and the abnormal alarm identification value of the diagnosis result data are forwarded.

[0077] Automatically parsing the measuring point configuration file can eliminate the need to configure parameters on a liquid crystal display or on a Web page accessed through the debugging interface. The automatically parsing measuring point configuration file in step C includes measuring point name, measuring point type, measuring point coefficient, function code, register address, word length and offset parameters. The above parameters are automatically configured, and the configuration parameters of different data protocols may be different.

[0078] The calling data protocol communication parameters in step C specifically automatically configure parameters such as port, baud rate, data bit, check mode, stop bit, interval time, byte stream mode, transmission delay, timeout, packet length, byte order and public address. The communication parameters of different data protocols are different.

[0079] The data protocol for this method is simple to adapt, has low implementation cost, short debugging time, and low professional requirements. It significantly reduces the risk of inaccurate data caused by manual input requirements and human errors, saves a lot of human resource costs, and at the same time enhances data processing capabilities, improves data collection quality, integrates machine learning diagnostic functions, and quickly analyzes, processes, diagnoses and makes decisions on key data, helping to discover and solve problems in a timely manner and avoid potential risks. This application can be targeted at thermal power stations, hydropower stations, nuclear power stations, geothermal power stations, wind power stations, solar power stations, garbage power stations, ocean power stations, etc. And the data protocols applicable to this application include national standard protocols, power protocols, Internet of Things protocols, industrial protocols and other protocols.

[0082] The power module is connected to the external power supply, and the power button on the power module is pressed to turn on the power module. The power indicator in the indicator group lights up; the RJ45 interface in the data interface group is directly connected to the external data source device through a network cable or indirectly connected to the external data source device through a networking device (such as a switch, firewall, etc.). The network IP address of the external data source device is configured through the LCD display. The edge computing module first performs a network communication test. If the network communication is normal, the multiple data protocols are automatically adapted, the key parameter information of the measurement point configuration file is automatically parsed, and the data protocol communication parameters are called from the parameter configuration database. For example, if it is a ModbusTCP data protocol, the data bit, check mode, stop bit, interval time, byte stream mode, transmission delay, timeout, packet length, and byte order parameters are automatically set. If it is an IEC104 data protocol, the time calibration mode, total call mode, cumulative collection mode, communication public address and other parameters are automatically set. Configure the data forwarding function parameters through the LCD display, automatically generate a forwarding data point table according to actual needs, and forward data to the external data receiving device according to the set forwarding protocol.

[0083] If a machine learning diagnosis is performed on a certain measurement point A to be diagnosed, the associated data B and the associated data C are the associated data of the measurement point A to be diagnosed, and the values ​​of the associated data B and the associated data C will affect the value of the measurement point A to be diagnosed, then the data value (A, B, C) at this moment is regarded as a working condition;

[0084] The measurement point A to be diagnosed is determined by the LCD display setting, and the associated data B and associated data C associated with the measurement point A to be diagnosed are selected. The edge computing module reads the database data in the storage module to obtain the historical data of the measurement point A to be diagnosed and the associated measurement points B and C, and determines the reference value of the measurement point A to be diagnosed under the corresponding numerical conditions of each associated measurement point. The steps for determining the reference value are as follows:

[0085] Set the threshold ε, the values ​​of the diagnostic point A under three typical working conditions are A1, A2, and A3, and the corresponding values ​​of the associated data B and associated data C are (B1, C1), (B2, C2), and (B3, C3). Search the historical database for the values ​​of the diagnostic point A under the working conditions of the associated data B and associated data C in the range of (B1-ε≤B≤B1+ε, C1-ε≤C≤C1+ε), (B2-ε≤B≤B2+ε, C2-ε≤C≤C2+ε), and (B3-ε≤B≤B3+ε, C3-ε≤C≤C3+ε). Take 100 times, and we have (A1 1 , A1 2 , A1 3 , ..., A1 99 , A1 100 ), (A2 1 , A22 , A2 3 , ..., A2 99 , A2 100 ), (A3 1 , A3 2 , A3 3 , ..., A3 99 , A3 100 ), then its average The following are the benchmark values ​​of the test point A to be diagnosed under three typical working conditions:

[0086] ;

[0087] Compare the current value of the data at the point to be diagnosed with the reference value under the current working condition and set the threshold , that is, when the current associated data B and associated data C values ​​are within the range of (B1-ε≤B≤B1+ε, C1-ε≤C≤C1+ε), (B2-ε≤B≤B2+ε, C2-ε≤C≤C2+ε), (B3-ε≤B≤B3+ε, C3-ε≤C≤C3+ε), if the current value of the measurement point A to be diagnosed exceeds , , range, it means that under the three typical working conditions, the A value of the measurement point to be diagnosed is abnormal, and the current A value of the measurement point to be diagnosed and the abnormal alarm identification value of the diagnosis result data are forwarded.
