[0083] In this embodiment, the connection standards between different components (such as communication protocols and interface types) are unified to avoid rule conflicts in manual design.

[0084] The connection relationship is accurately described by numerical parameters, interval parameters and / or enumerated parameters to provide quantitative basis for subsequent steps.

[0092] Step 111: Obtain electrical data corresponding to at least one of the following systems: the rocket's power system, control system, propulsion system, telemetry system, and safety system.

[0093] The electrical data includes electrical component data and connection relationship data.

[0094] In this embodiment, the focus is on the electrical requirements of a specific system (such as a propulsion system) to ensure that the generated schematic diagram conforms to the actual application scenario.

[0095] Simultaneously obtain component parameters and connection relationships to avoid deviations in schematic design due to missing data.

[0100] Step 1212: Normalize the first parameter data to obtain the second parameter data;

[0101] Step 1213, according to V=[p1, p2, ..., p n ], thus constructing the first feature vector;

[0102] Step 122: Based on the modular data of electrical components or modular data of component connection relationships in the preset electrical module library, determine the feature vector group U=[U1, U2, ..., U...]. m ];

[0103] Where U is the feature vector set, U j U is the second feature vector corresponding to the modular data of each electrical component or the modular data of component connection relationships, j=1,2,...,m, where m is the total number of modular data of each electrical component or the modular data of component connection relationships. j =[q1, q2, ..., q n ], q i This includes the parameter data corresponding to the modular data of each electrical component or the modular data of component connection relationships; specifically, it may include:

[0104] Step 1221: Normalize the modular data of electrical components or modular data of component connection relationships in the preset electrical module library to obtain the third parameter data;

[0105] Step 1222, according to U=[U1, U2, ..., U m ], thus constructing the first feature vector group;

[0106] Step 123, according to ,

[0107] Determine the similarity between the first feature vector and each of the second feature vectors;

[0108] Among them, Sim j w represents the similarity between the first feature vector and each of the second feature vectors. i Here, each parameter represents a weighting coefficient, and `match` is the parameter matching function; specifically, it can include:

[0109] For numerical parameters, ;

[0110] Where α is the attenuation coefficient;

[0111] For interval parameters, ;

[0112] For enumerated parameters, ;

[0113] Where β is the compatibility matching score;

[0114] Step 124: The electrical component modular data or component connection relationship modular data with the highest similarity between the first feature vector and each of the second feature vectors is determined as the required electrical component data.

[0115] In this embodiment, different dimensional parameters (such as voltage 28V, current 10A) are converted into dimensionless values in the interval 0-1 (such as voltage 0.5, current 0.4), avoiding matching deviation caused by different dimensions.

[0116] The component / connection relationship data in the preset electrical module library is normalized to generate a feature vector group, ensuring that the input data vector and the vector in the library are compared in the same dimensional space, avoiding matching errors caused by data preprocessing differences.

[0117] The deviation is quantified by a decay function, and the decay coefficient can be adjusted according to engineering requirements, making the matching more consistent with the actual design priority.

[0118] The compatibility is measured by the intersection ratio, which directly reflects the interval overlap and avoids misjudgment caused by interval boundary differences.

[0119] The compatibility score is used to determine the matching degree of enumeration values such as protocols and interfaces, supporting fuzzy matching and improving design flexibility.

[0120] The weight coefficient can be adjusted according to the importance of the parameter, making the matching result more consistent with the engineering safety requirements.

[0121] The highest similarity module is automatically selected to avoid subjective bias when manually checking historical data.

[0122] In an optional embodiment of the present application, in step 13, a first electrical schematic diagram is automatically generated based on the required module data, including:

[0123] In step 131, the electrical component modularization data in the required module data is used to perform module layout to obtain a first schematic diagram.

[0124] In step 132, the component connection relationship modularization data in the required module data is used to perform line connection on the first schematic diagram to obtain a second schematic diagram.

[0125] In step 133, the second schematic diagram is run to obtain a first electrical schematic diagram.

[0126] Specifically, based on the determined electrical component modularization data, the determined electrical component modularization data is classified according to the function type, the relative positions of the components in the schematic diagram are determined based on the system structure of the launch vehicle and the physical position relationship of the electrical components, the standardized graphic symbol of each component is generated, and its key parameters are labeled:

[0127] Based on the determined component connection relationship modularization data, line connection is automatically performed: the interface definition and connection relationship parameters of each component are analyzed, the connection lines to be established are determined: the key parameters of each connection line are labeled.

[0131] According to the simulation results, necessary adjustments are made to the schematic diagram, including: optimizing the layout of the line to reduce interference, adjusting the component parameters to meet the performance requirements, and correcting the connection relationship to ensure normal signal transmission.

[0132] In this embodiment, the components are arranged according to the function type and physical location, the standardized graphic symbols are generated, and the readability and maintainability of the schematic diagram are improved.

[0133] Through the simulation model (such as power output voltage, cable resistance), the signal integrity, power distribution, etc. are verified, the design defects are found in advance, and the hardware debugging cost is reduced.

[0134] In an optional embodiment of the present application, in step 14, the first electrical schematic diagram is verified for indicators to obtain a second electrical schematic diagram, including:

[0140] Wherein, P is the actual working power, I is the actual working current, R is the resistance, and U is the actual working voltage;

[0141] Check whether the actual working power of the component exceeds the rated power of the component. If it exceeds, replace the appropriate component.

For example, by normalizing parameters (operating voltage, transmission rate, etc.), a feature vector is constructed, and the similarity with the vector group in the module library is calculated to quickly locate the required module, avoiding the tedious process of manually checking historical data.

[0183] Automatically laying out modules and connection lines (steps 131-132), combined with simulation verification (step 133), realizes the closed-loop automation from data matching to schematic diagram generation.

[0184] Match functions are designed for numerical, interval, and enumerated parameters (e.g., step 123): numerical parameters calculate deviations through decay coefficients (e.g., the matching degree of 25V working voltage and 28V in the module library); interval parameters judge compatibility through the proportion of intersection (e.g., the overlapping degree of temperature range [-10℃, +40℃] and [-10℃, +50℃] in the module library); enumerated parameters verify protocol consistency through compatibility scores (e.g., the matching of communication protocol CAN).

[0185] Wire current-carrying capacity troubleshooting (step 14) calculates a safety threshold, such as a cable length of 2m and a wire with a cross-sectional area. If the actual current exceeds the safety threshold, replace the thicker wire or optimize the layout to avoid overheating.

[0186] Component power verification (step 14) verifies the actual power. If the resistance working power exceeds the rated value, replace the high-power device to ensure circuit safety.

[0187] Simulation verification (step 133) covers signal integrity, power distribution, and communication delay dimensions. For example, input simulation models with parameters such as power module output voltage and cable resistance to detect problems such as voltage drop and electromagnetic interference in advance, reducing the risk of electrical failure after rocket launch.

[0188] Split the component parameters of historical schematics into numerical, interval, and enumerated types (e.g., step 1021), such as the working voltage of the power module defined as a numerical parameter of 28V and the temperature range defined as an interval of [-10℃, +50℃], forming a unified data structure for design reuse and collaborative development across different projects.

[0189] Establishing a connection relationship base class (e.g., step 1031) unifies the connection rules of control unit-telemetry transmitters and other interfaces, ensuring the standardization of line labeling (cable length, signal delay, etc.) in the schematic.

[0190] When laying out modules (step 131), generate standardized graphical symbols based on component functions and physical locations, and label key parameters (such as power voltage and control module signal characteristics), avoiding the problem of non-uniform symbols drawn by hand, improving the readability and maintainability of the schematic.

[0191] When the launch vehicle system is upgraded (e.g., replacing a new engine controller), only the corresponding component data in the module library needs to be updated (step 101), and a new schematic can be generated through feature vector matching, without the need to redesign the entire circuit, shortening the iteration cycle.

[0192] Simulation results can guide design optimization (e.g., step 133), such as adjusting the layout to reduce electromagnetic interference or modifying component parameters to meet voltage drop requirements, achieving continuous improvement of the design.
