[0050] The data acquisition unit is used to collect the electrical state parameters, mechanical state parameters and safety protection state parameters of the target pulse rectifier, and send them to the electrical state detection unit, the mechanical state detection unit and the safety protection analysis unit respectively.

[0051] The cloud database is used to store the electrical operation status classification table of the target pulse rectifier, the mechanical operation status classification table of the target pulse rectifier, and the safety protection status classification table of the target pulse rectifier.

[0052] The electrical state detection unit is used to monitor the electrical state parameters corresponding to the target pulse rectifier at the current time point. The specific monitoring process is as follows:

[0053] The unit time is equally divided into i time points, i = 1, 2, 3 ... N, and the output voltage of the target pulse rectifier under normal conditions in the unit time is monitored, with time as the horizontal coordinate and the output voltage as the vertical coordinate. Based on this, the output voltage coordinate system of the target pulse rectifier is established, and the linear shape of the output voltage changing with time in the unit time is named the output voltage waveform line, and the change state of each upper peak value and each lower peak value in the output voltage waveform line is analyzed, specifically:

[0054] An upper peak value comparison interval is set, and each upper peak value in the output voltage waveform line is substituted into the preset upper peak value comparison interval for comparative analysis. When the corresponding upper peak value is within the preset upper peak value comparison interval, the corresponding upper peak value is calibrated as a fixed upper peak value. Conversely, when the corresponding upper peak value is outside the preset upper peak value comparison interval, the corresponding upper peak value is calibrated as a variable upper peak value.

[0055] A lower peak value comparison interval is set, and each lower peak value in the output voltage waveform line is substituted into the preset lower peak value comparison interval for comparative analysis. When the corresponding lower peak value is within the preset lower peak value comparison interval, the corresponding lower peak value is calibrated as a fixed lower peak value. Conversely, when the corresponding lower peak value is outside the preset lower peak value comparison interval, the corresponding lower peak value is calibrated as a variable upper peak value.

[0056] Calculate the proportions of the fixed upper peak and the fixed lower peak respectively, and mark them as rv1 and rv2 respectively, and perform calculation and analysis on them, and obtain the waveform coefficient rv* of the output voltage of the target pulse rectifier according to the formula rv*=ρ1×rv1+ρ2×rv2, wherein ρ1 and ρ1 are normalization factors of the proportion of the fixed upper peak and the proportion of the fixed lower peak respectively, and ρ1 and ρ1 are natural numbers greater than 0, and the normalization factor is used to represent the coefficient for converting the data of the proportion of the fixed upper peak and the proportion of the fixed lower peak into a dimensionless form;

[0057] Thus, the waveform factor rv* of the output voltage of the target pulse rectifier is obtained.

[0058] Apply a load condition to the target pulse rectifier in the same unit time, thereby monitoring the amplitude of the output voltage of the target pulse rectifier under the load state and calculating its standard deviation. According to the formula Get the standard deviation of the output voltage amplitude of the target pulse rectifier, where fz i represents the i-th time data point, fz * is the average value of all data, that is, the average value of the amplitude of the output voltage per unit time, and N is the size of all data sets;

When the power load value of the target circuit is greater than the pre-set power load threshold, the power load state of the corresponding target circuit is determined to be power overload. Conversely, when the power load value of the target circuit is less than or equal to the pre-set power load threshold, the power load state of the corresponding target circuit is determined to be normal. According to the generated power overload, an overload tripping protection operation is triggered, and the ratio of the number of actual overload tripping protection operations to the number of rated overload tripping protection operations per unit time is counted, thereby obtaining a first protection parameter; Monitor the current value flowing through each target electronic component of the pulse rectifier in real time, compare and analyze the current value flowing through each target electronic component with a preset current threshold value, when the current value flowing through the target electronic component is greater than the preset current threshold value, the current state of the corresponding target electronic component is determined to be an overcurrent state, when the current value flowing through the target electronic component is equal to the preset current threshold value, the current state of the corresponding target electronic component is determined to be a normal state, when the current value flowing through the target electronic component is less than the preset current threshold value, the current state of the corresponding target electronic component is determined to be a short-circuit state; According to the generated overcurrent state or short circuit state, a short circuit tripping protection operation is triggered, and the ratio of the number of actual short circuit tripping protection operations to the number of rated short circuit tripping protection operations per unit time is counted, thereby obtaining a second protection parameter; Integrate and analyze the first protection parameter and the second protection parameter of the target pulse rectifier, thereby obtaining a safety protection factor of the target pulse rectifier; The safety protection factor corresponding to the target pulse rectifier at the current time point is compared and matched with the safety protection status classification table stored in the cloud database, thereby obtaining the safety protection status level corresponding to the target pulse rectifier, wherein each safety protection factor of the target pulse rectifier has a corresponding safety protection status level; The state feedback management unit is used to perform corresponding feedback analysis and control operations based on the electrical operation state, mechanical operation state, and safety protection operation state of the target pulse rectifier at the current time point. The specific analysis steps are as follows: the received electrical health level and electrical abnormality level, normal working state level, safety protection level, and medium safety protection level are displayed and explained through the display terminal; According to the generated electrical maintenance level, abnormal working state level, and low safety protection level, the target pulse rectifier is shut down for maintenance, and the electrical components, mechanical components, and protection components of the target pulse rectifier are repaired in turn; The cloud database is used to store the electrical operation status classification table of the target pulse rectifier, the mechanical operation status classification table of the target pulse rectifier, and the safety protection status classification table of the target pulse rectifier.
