Therefore, higher technical requirements are imposed on communication interfaces, that is, not only need to support the interoperability between multiple avionics protocols, but also need to have good electrical compatibility and dynamic adaptation capabilities to cope with changing communication environments and device states.
[0003] The current mainstream solution is a multi-protocol communication architecture based on the combination of a predefined protocol mapping table and a fixed impedance matching module. This solution realizes the static semantic mapping between mainstream avionics protocols by constructing a standardized protocol conversion rule library; combined with an adjustable impedance circuit module at the hardware level, it completes the physical layer adaptation between different communication interfaces to a certain extent. Existing solutions have some inherent defects, including that the dynamic changes in the semantic relationships between protocols cannot be effectively captured, resulting in the difficulty of the preset mapping rules to adapt to new protocols or non-standard data formats; the fixed impedance adjustment mechanism lacks the real-time perception ability of the on-site interface state and cannot make fine adjustments according to environmental changes; the two processes of protocol conversion and physical layer matching are independent of each other and lack a collaborative optimization mechanism, which limits the improvement of the overall communication performance.

[0023] Figure 1 It is a flowchart of the processing method for the multi-protocol data communication interface of civil aviation measuring instruments provided by the embodiments of the present invention. As Figure 1 shown, the method includes: Aiming at the core problems faced by the multi-protocol communication interfaces of civil aviation measuring instruments in complex electromagnetic environments, such as the difficulty in adapting to protocol heterogeneity and the dynamic mismatch of interface impedance, traditional solutions have defects such as the collaborative failure caused by the separate optimization of protocol conversion and physical layer impedance matching, the inability of static parameter configuration to adapt to the real-time changes of interface states, and the insufficient guarantee of semantic-level data consistency. In view of these problems, the research and development idea of the present invention is: by constructing a compatibility map that integrates protocol semantic mapping and impedance parameter constraints, to achieve the dynamic association between protocol rules and interface electrical characteristics; combining the real-time tuning of the adaptive impedance matching network and the adaptive optimization of data frame conversion rules to form a closed-loop feedback mechanism between the physical layer and the protocol layer, so as to solve the problems of protocol syntax conflicts, interface impedance drift and loss of key data semantics when connecting multi-vendor devices, and significantly improve the communication reliability and environmental adaptability of the multi-protocol interfaces of civil aviation measuring instruments under complex working conditions. Based on this, the present invention provides a processing method for the multi-protocol data communication interfaces of civil aviation measuring instruments, such as Figure 1 , including: Step 101: Based on the multi-protocol database of civil aviation measuring instruments and the database of communication interface electrical characteristics, construct a protocol compatibility map, where the protocol compatibility map defines the semantic mapping relationship between the first avionics protocol and the second avionics protocol, and the impedance parameter constraint conditions of the communication interface.
[0024] In this step, the multi-protocol database refers to a structured database that stores the syntax rules, field definitions and semantic descriptions of different avionics protocols; the communication interface electrical characteristics database refers to a measured data set that records the electrical parameters such as equivalent inductance and equivalent capacitance of the physical interface of civil aviation measuring instruments; the protocol compatibility map refers to a hierarchical data structure that defines the semantic mapping relationship between protocols and interface impedance constraint conditions; the first avionics protocol refers to the source protocol to be converted, such as ARINC 429; the second avionics protocol refers to the target protocol, which adopts a virtual link identifier and a binary data frame structure; the semantic mapping relationship refers to the semantic equivalence correspondence relationship between the source protocol field and the target protocol field; the impedance parameter constraint conditions refer to the allowable fluctuation range of the interface equivalent inductance and capacitance, which is set based on the statistical distribution of historical data.
[0025] In an embodiment of the present invention, first, a set of syntax structure fields of a first avionics protocol and a second avionics protocol is extracted from a multi-protocol database of civil aviation measuring instruments, and a two-way mapping relationship is established for fields with the same semantics to generate an initial semantic mapping relationship table; subsequently, a set of historical equivalent inductance measurement values and a set of equivalent capacitance measurement values of each data communication interface are obtained, and an equivalent inductance probability distribution interval and an equivalent capacitance probability distribution interval of each interface are calculated; then, each field mapping relationship in the initial semantic mapping relationship table is associated with the impedance probability distribution interval of the corresponding interface to generate a triple relationship node including an interface identifier, a field mapping weight, and an impedance constraint interval; finally, clustering analysis is performed on the nodes, similar nodes are merged to form a protocol conversion group, and priorities are determined, and finally a protocol compatibility map is constructed.
[0026] Step 102: Configure an adaptive impedance matching network, and adjust the equivalent inductance value and the equivalent capacitance value of the adaptive impedance matching network according to the impedance parameter constraint conditions to generate a set of impedance configuration parameters.
[0027] In this step, the adaptive impedance matching network refers to a circuit composed of programmable inductance and capacitance elements; the equivalent inductance value and the equivalent capacitance value refer to the equivalent circuit parameters exhibited by the matching network at a specific frequency; the set of impedance configuration parameters refers to a set of optimized combinations of inductance and capacitance values.
[0028] In an embodiment of the present invention, first, based on the impedance parameter constraint conditions in the protocol compatibility map, the adjustment ranges of the equivalent inductance value and the equivalent capacitance value of the adaptive impedance matching network are determined; subsequently, the equivalent inductance value and the equivalent capacitance value of the matching network are adjusted in real time through programmable elements such as digital potentiometers or varactor diodes to approximate the impedance characteristics of the target interface. During the adjustment process, an impedance matching degree calculation formula is used to evaluate the matching effect, and iterative optimization is performed until a preset threshold is met; finally, the optimized combination of the equivalent inductance value and the equivalent capacitance value is generated into a set of impedance configuration parameters for subsequent interface state adaptation.
[0029] Step 103: Based on the semantic mapping relationship, convert the original data frame of the first avionics protocol into a target data frame conforming to the second avionics protocol.
[0030] In this step, the original data frame refers to the original data unit that has not been converted by the first protocol; the target data frame refers to the data unit conforming to the second protocol format, which is generated through syntax reconstruction and semantic mapping.
[0031] In an embodiment of the present invention, first, according to the semantic mapping relationship in the protocol compatibility map, the syntax structure of the first avionics protocol original data frame is parsed to identify the source field tags and data content; subsequently, the source field tags are mapped to the target field tags of the second avionics protocol, and the data frame structure is reconstructed according to the syntax rules of the target protocol. During the conversion process, data range constraint parameters are used to truncate or scale the over-limit values to ensure that the generated target data frame complies with the format specifications of the second protocol.
[0032] Step 104: Obtain the impedance measurement values of each data communication interface of the civil aviation measuring instrument, so as to match the candidate impedance configuration parameters adapted to the data communication interface of the abnormal protocol conversion group from the impedance configuration parameter set, and generate a dynamic impedance strategy based on the candidate impedance configuration parameters.
[0033] In this step, the impedance measurement value refers to the interface equivalent impedance parameter obtained in real time by a vector network analyzer; the abnormal protocol conversion group refers to the protocol conversion group with continuously over-limit impedance deviation; the candidate impedance configuration parameter refers to the potential adaptation parameter screened from the configuration parameter set, which needs to be used after conflict resolution; the dynamic impedance strategy refers to the impedance adjustment scheme including the main and standby parameter combinations and switching conditions to ensure the stability of the interface.
[0034] In an embodiment of the present invention, first, the physical connection signal strength of each data communication interface is monitored in parallel, and the analyzer obtains the real-time impedance measurement value; secondly, the measurement value is compared with the impedance constraint interval of the corresponding protocol conversion group in the protocol compatibility map to calculate the impedance deviation. When the impedance deviation of a certain protocol conversion group continuously exceeds the preset exclusive threshold, it is marked as an abnormal protocol conversion group, and the time-frequency domain reflection characteristics of its interface are collected; subsequently, in combination with the impedance sensitivity index, the impedance constraint interval of this group is dynamically expanded, and the adapted candidate parameters are screened from the impedance configuration parameter set; finally, the candidate parameters are resolved and fused according to the priority order to generate a dynamic impedance strategy.
[0035] Step 105: According to the semantic consistency verification result of the target data frame, adjust the association parameters of the semantic mapping relationship and the preset data frame conversion rule to generate an adaptive protocol conversion rule set.
[0036] In this step, the semantic consistency verification result refers to the quantitative evaluation result of the semantic consistency between the target data frame and the source data, including field missing and over-limit identification; the association parameter refers to the priority weight and data range constraint bound to the semantic mapping in the protocol conversion rule; the adaptive protocol conversion rule set refers to the dynamically optimized field mapping order and constraint rule set to improve the conversion reliability.
[0037] In the embodiment of the present invention, first, the semantic consistency check result of the target data frame is parsed, and the field missing identifier and the data range overrun identifier are extracted; secondly, the missing times and overrun deviation amounts of each field mapping relationship are counted, and the mapping priority parameter is de-weighted, and at the same time, the data range constraint parameter is extended according to the overrun deviation direction; then, the adjusted priority parameter and the extended constraint parameter are bound to the original semantic mapping relationship to generate a bound mapping relationship set; then, according to the adjusted priority parameter, the field order of the data frame conversion rule is reorganized, and the conflicting rules are removed to generate a preliminary protocol conversion rule set; finally, an adaptive protocol conversion rule set is generated through the filtering rules of the integrity threshold and the consistency threshold.
[0038] Step 106: Co-optimize the dynamic impedance strategy and the adaptive protocol conversion rule set to generate communication interface adaptive parameters to achieve adaptive processing of the multi-protocol data communication interface of the civil aviation measuring instrument.
[0039] In this step, the co-optimization operation refers to the decision-making process of jointly optimizing the impedance matching parameter and the protocol conversion rule to solve the cross-layer conflict; the communication interface adaptive parameter refers to the finally generated joint control parameter of the physical layer and the protocol layer to guide the real-time adaptation of the interface.
[0040] In the embodiment of the present invention, first, the impedance matching parameter in the dynamic impedance strategy and the protocol conversion parameter in the adaptive protocol conversion rule set are extracted; secondly, the impedance matching degree and the protocol conversion success rate are balanced; then, the feasibility of the optimization result is verified, and the parameter combinations that cause the impedance sensitivity index to drop by more than 5% are removed; finally, communication interface adaptive parameters including the primary and backup parameter combinations and the switching conditions are generated, and the primary parameter is preferentially used, and the backup parameter is switched according to the priority when the interface state changes.
[0041] For example, first, based on the multi-protocol database, the field sets of the ARINC 429 and AFDX protocols are extracted, and the mapping relationship table of keyword fields such as fuel flow and cabin pressure is generated through semantic matching. Secondly, the equivalent inductance historical data (mean 50 nH, standard deviation 2 nH) of the fuel flowmeter interface is obtained from the interface electrical characteristic library, and a constraint interval of 50 nH ± 5% is fitted and bound to the field mapping relationship as a triple node; then, it is detected that the impedance value of a certain fuel flowmeter interface exceeds the limit to 55 nH three times continuously, which is marked as an abnormal protocol conversion group, and its constraint interval is extended to 55 nH ± 5%, and candidate parameters (such as 53 nH / 200 pF) are screened from the configuration parameter set; then, according to the priority, the candidate parameters are allocated, and a dynamic impedance strategy is generated by fusion; at the same time, semantic verification finds that the fuel flow field is missing, its mapping priority is de-weighted and the data range is extended, and an adaptive protocol conversion rule set is reorganized; finally, the impedance strategy and the protocol rule are co-optimized to generate interface adaptive parameters to achieve stable communication of the interface.
[0042] In the embodiment of the present invention, the semantic mapping and impedance constraint are dynamically associated through a protocol compatibility map, solving the problem of collaborative failure caused by the separation of protocol conversion and physical layer adaptation in the traditional solution; the adaptive impedance matching network and dynamic policy generation mechanism improve the real-time response ability to interface impedance drift; the rule optimization driven by semantic consistency ensures the integrity of key data; finally, through cross-layer collaborative optimization, the stability and reliability of multi-protocol interfaces in complex electromagnetic environments are significantly improved.
[0043] To solve the problems of inaccurate semantic mapping and lack of interface impedance matching constraints between different avionics protocols, this step constructs a protocol compatibility map to define semantic mapping relationships and impedance parameter constraint conditions. The present invention provides a specific embodiment. Step 101: Based on the multi-protocol database of civil aviation measuring instruments and the electrical characteristic database of communication interfaces, construct a protocol compatibility map, where the protocol compatibility map defines the semantic mapping relationship between the first avionics protocol and the second avionics protocol, and the impedance parameter constraint conditions of the communication interface, specifically including the following steps: Step 111: Based on the multi-protocol database of civil aviation measuring instruments, obtain the syntax structure field sets of the first avionics protocol and the second avionics protocol, and perform bidirectional mapping on the syntax structure fields with the same semantics in the syntax structure field sets to generate an initial semantic mapping relationship table.

[0045] In the embodiment of the present invention, first, extract the syntax structure field sets of the first avionics protocol and the second avionics protocol from the multi-protocol database of civil aviation measuring instruments; secondly, perform bidirectional mapping on the syntax structure fields with the same semantics through a semantic similarity matching algorithm; then assign initial weights to the mapping relationships to generate an initial semantic mapping relationship table including field pairs, weights, and mapping directions.
[0046] Step 112: Obtain the equivalent inductance measurement value set and equivalent capacitance measurement value set of each data communication interface of the civil aviation measuring instrument from the electrical characteristic database of the communication interface, and respectively fit the equivalent inductance measurement value set and equivalent capacitance measurement value set of each data communication interface to generate the equivalent inductance probability distribution interval and equivalent capacitance probability distribution interval of each data communication interface.

[0048] In an embodiment of the present invention, first, the historical equivalent inductance measurement value set and equivalent capacitance measurement value set of each data communication interface are obtained from the communication interface electrical characteristic database. Subsequently, the Gaussian distribution fitting algorithm is used to calculate the equivalent inductance mean and standard deviation of each interface respectively, generate the equivalent inductance probability distribution interval, and the equivalent capacitance probability distribution interval. During the fitting process, outliers are removed to ensure that the distribution interval covers the measured data, thereby improving the reliability of the interval.
[0049] Step 113: Based on the equivalent inductance probability distribution interval and the equivalent capacitance probability distribution interval, associate each field mapping relationship in the initial semantic mapping relationship table with the corresponding data communication interface to generate a triple relationship node, where the triple relationship node includes a data communication interface identifier, a field mapping relationship weight, and an impedance constraint interval.

[0051] In an embodiment of the present invention, first, each field mapping relationship in the initial semantic mapping relationship table is associated with the equivalent inductance probability distribution interval and the equivalent capacitance probability distribution interval of the corresponding data communication interface; subsequently, a field mapping relationship weight is assigned to each field mapping relationship, and combined with the interface identifier and the impedance constraint interval, to generate a triple relationship node.
[0052] Step 114: According to the overlap degree of the impedance constraint intervals, perform clustering analysis on the triple relationship nodes, and merge the nodes that meet the preset conditions into the same protocol conversion group to generate multiple protocol conversion groups with common impedance characteristics.
[0053] In this step, the clustering analysis operation refers to a data analysis method for grouping similar nodes, such as hierarchical clustering based on the overlap degree; the common impedance feature refers to the impedance constraint interval feature shared by the interfaces within the same protocol conversion group; the protocol conversion group refers to a set of field mapping relationships with similar impedance constraint features.

[0074] Embodiments of the present invention solve the problems of lag in interface impedance drift detection and failure of static interval adaptation in traditional solutions through real-time monitoring and dynamic expansion mechanisms; an expansion strategy based on time-frequency domain reflection characteristics and sensitivity indices improves the adaptation accuracy of abnormal interfaces; conflict resolution and fusion processing ensure multi-parameter collaborative optimization, significantly enhancing the stability and anti-interference ability of the interfaces of civil aviation measuring instruments under complex working conditions.
[0075] To solve the problem of matching failure caused by conflicts between candidate impedance configuration parameters, this step generates a dynamic impedance strategy through conflict feature recognition and parameter fusion. The present invention provides a specific embodiment. In step 405, conflict resolution and fusion processing are performed on the set of candidate impedance configuration parameters to generate a dynamic impedance strategy, which specifically includes the following steps: Step 451: Calculate the absolute values of the differences between the equivalent inductance value and the equivalent capacitance value of each candidate impedance configuration parameter in the set of candidate impedance configuration parameters and the boundary values of the extended impedance constraint interval to generate an inductance deviation amount and a capacitance deviation amount.

[0082] In this step, the target candidate impedance configuration parameter refers to the candidate parameter that meets the extended constraint conditions and has the smallest sum of deviations; the selected parameter refers to the optimal candidate parameter determined through conflict screening.
[0083] In the embodiment of the present invention, first, screen out the candidate parameters within the conflict feature range where both the equivalent inductance and capacitance values are within the extended impedance constraint interval; subsequently, calculate the sum of the inductance deviation and the capacitance deviation for each parameter, and select the parameter with the smallest sum as the selected parameter.
[0084] Step 454: Remove the candidate impedance configuration parameters in the candidate impedance configuration parameter set that have an overlapping conflict feature range with the equivalent inductance value and the equivalent capacitance value of the selected parameter to obtain an intermediate impedance configuration parameter set.

[0086] In the embodiment of the present invention, first, identify the parameters in the candidate impedance configuration parameter set that have an overlapping conflict feature range with the equivalent inductance value and the equivalent capacitance value of the selected parameter; subsequently, remove the parameters with the overlapping conflict feature range from the set to form an intermediate impedance configuration parameter set.
[0087] Step 455: Calculate the weighted result of the deviation of each intermediate candidate impedance configuration parameter in the intermediate candidate impedance configuration parameter set, and use the intermediate candidate impedance configuration parameter with the lowest weighted result of the deviation as the reference parameter.
[0088] In this step, the weighted result of the deviation refers to the comprehensive score calculated by the inductance and capacitance deviations according to the preset weights, and the weights reflect the physical layer adaptation priorities; the reference parameter refers to the parameter with the best comprehensive score in the intermediate set and serves as the fusion reference.
[0089] In the embodiment of the present invention, first, calculate the weighted result of the deviation for each parameter in the intermediate impedance configuration parameter set, and the weighted result is the product of the inductance deviation and the preset inductance weight plus the product of the capacitance deviation and the preset capacitance weight; subsequently, select the parameter with the lowest weighted result as the reference parameter.
[0090] Step 456: Superimpose the equivalent inductance value and equivalent capacitance value of the intermediate candidate impedance configuration parameters whose weighted result difference of all deviation amounts is within the preset tolerance range, and the reference parameter to generate a fusion parameter.

[0094] In this step, the combining operation refers to the process of integrating the preferred parameter and the fusion parameter to form a final strategy.
[0095] In the embodiment of the present invention, first, the selected parameter and the fusion parameter are combined into a candidate solution set. If the equivalent inductance value or equivalent capacitance value exceeds the original impedance constraint interval due to parameter superposition, truncation processing is performed according to the interval boundary value; subsequently, it is verified whether the candidate solution satisfies the extended constraint conditions of all abnormal protocol conversion groups; finally, after eliminating the conflict items, a dynamic impedance strategy including the primary and backup parameter combinations is generated.
[0096] The embodiment of the present invention solves the interface mismatch problem caused by multi-parameter adaptation conflicts through precise quantification of candidate parameter deviation to identify the conflict range and multi-dimensional fusion optimization; based on the weighted scoring and conflict resolution mechanism, a primary and backup strategy is generated to improve the stability and anti-interference ability of the civil aviation measuring instrument interface under complex working conditions.
[0097] To solve the protocol conversion error caused by the missing semantic mapping field and the data range exceeding the limit, in this step, an adaptive protocol conversion rule set is generated by adjusting the priority parameter and the extended constraint range. The present invention provides a specific embodiment, step 105, according to the semantic consistency verification result of the target data frame, adjust the association parameter between the semantic mapping relationship and the preset data frame conversion rule to generate an adaptive protocol conversion rule set, which specifically includes the following steps: Step 501: Analyze the field missing identifier and data range exceeding limit identifier in the semantic consistency verification result of the target data frame, and according to the field missing identifier and data range exceeding limit identifier, count the field missing times and the exceeding limit deviation amount corresponding to the semantic mapping relationship.

[0100] Step 502: According to the field missing times, the priority parameter of the semantic mapping relationship is de-weighted to obtain the adjusted priority parameter.
[0101] In this step, the priority parameter refers to the weight value reflecting the importance of the field mapping relationship, and the initial value is set based on the semantic criticality of the field; the de-weighting operation refers to the adjustment process of reducing the priority parameter proportionally according to the field missing times; the adjusted priority parameter refers to the de-weighted field mapping weight value and is used to guide the rule reorganization.
[0102] In the embodiment of the present invention, first, the original priority parameter is multiplied by a preset de-weighting coefficient to generate the adjusted priority parameter; then, the de-weighting coefficient is dynamically adjusted according to the sensitivity of the protocol conversion group, and the de-weighting amplitude of the key field is lower than that of the non-key field.
[0103] Step 503: Based on the overlimit deviation amount, the constraint range of the associated parameter of the preset data frame conversion rule is extended and adjusted to generate the updated associated parameter.
[0104] In this step, the preset data frame conversion rule refers to the predefined protocol field mapping order and data constraint rule set; the extension and adjustment operation refers to the operation of dynamically expanding or contracting the data constraint range according to the overlimit deviation amount; the updated associated parameter refers to the set of adaptation parameters including the extended data constraint range and the adjusted priority.
[0105] In the embodiment of the present invention, first, the associated parameter in the preset data frame conversion rule is extended and adjusted based on the overlimit deviation amount. For positive overlimit, the upper limit of the constraint range is extended according to the proportion of the overlimit deviation amount, and for negative overlimit, the lower limit of the constraint range is contracted according to the proportion of the deviation amount; then, the extended constraint range is merged with the original parameter to generate the updated associated parameter.
[0106] Step 504: Bind the adjusted priority parameter and the updated association parameter to the semantic mapping relationship to generate a set of bound mapping relationships.

The binding process includes attaching the adjusted priority parameter and the extended constraint scope to each field mapping relationship; subsequently, a set of bound mapping relationships containing complete adaptation information is formed.
[0109] Step 505: Reorganize the field mapping order of the preset data frame conversion rule according to the adjusted priority parameter to generate a preliminary protocol conversion rule set.

[0112] Step 506: Extract the target protocol conversion rules in the preliminary protocol conversion rule set that meet the preset integrity threshold and consistency threshold to generate an adaptive protocol conversion rule set.
[0113] In this step, the preset integrity threshold refers to the minimum proportion of key fields that the protocol conversion rule must cover; the consistency threshold refers to the requirement that the mapping directions of the same field in all rules are completely consistent; the target protocol conversion rule refers to a set of highly reliable conversion rules filtered by the threshold.
[0114] In the embodiment of the present invention, first, the rules that meet the preset integrity threshold and consistency threshold are extracted from the preliminary protocol conversion rule set. The integrity threshold requires that the rule must cover the mapping relationships of all key fields, and the consistency threshold requires that the mapping directions of the same field in all rules are consistent; subsequently, the conflicting or incomplete rules are filtered out by the threshold to generate the final adaptive protocol conversion rule set.
[0115] The embodiment of the present invention solves the problems of field missing and data overlimit caused by the solidification of protocol conversion rules in traditional solutions through dynamic demotion and constraint extension mechanisms; based on priority-driven rule reorganization and threshold filtering, the reliability of key field conversion and data consistency are improved, and the semantic integrity and adaptability of the multi-protocol interface of civil aviation metering instruments in complex data scenarios are significantly enhanced.
[0116] In order to solve the protocol conversion compliance problem caused by insufficient directional constraints of over-limit deviation, this step generates updated associated parameters by directional expansion of the constraint range and conflict detection. The present invention provides a specific embodiment, step 503, based on the over-limit deviation, the constraint range of the associated parameters of the preset data frame conversion rule is expanded and adjusted to generate updated associated parameters, specifically including the following steps: Step 531: Identify whether the over-limit direction of the target field in the semantic mapping relationship is a positive over-limit or a negative over-limit, so as to extract the over-limit amplitude value corresponding to the target field.
[0117] In this step, the over-limit direction refers to the direction in which the target field value exceeds the preset constraint range, which is divided into positive over-limit and negative over-limit; positive over-limit refers to the state in which the actual value of the target field exceeds the upper limit value of the preset constraint range, and the upper limit needs to be expanded to adapt to data fluctuations; negative over-limit refers to the state in which the actual value of the target field is lower than the lower limit value of the preset constraint range, and the lower limit needs to be expanded to avoid data loss; the over-limit amplitude value refers to the absolute difference between the actual value of the target field and the constraint boundary value, which is used to quantify the amplitude of the expansion adjustment.
[0118] In an embodiment of the present invention, the out-of-limit direction of the target field in the semantic mapping relationship is first identified, that is, the direction in which the target field value exceeds the preset constraint range is determined to be a positive over-limit or a negative over-limit; then the corresponding over-limit amplitude value is extracted, that is, the absolute difference between the actual value of the target field and the constraint boundary value.
[0119] Step 532: Expand the boundary constraint range of the associated parameters of the preset data frame conversion rule according to the exceeding direction to generate a preliminary extended constraint range, wherein when the exceeding direction is a positive exceeding direction, the upper limit value of the preliminary extended constraint range is expanded according to the exceeding amplitude value, and when the exceeding direction is a negative exceeding direction, the lower limit value of the preliminary extended constraint range is expanded according to the exceeding amplitude value.

[0121] In an embodiment of the present invention, the overrun direction performs an expansion operation on the boundary constraint range of the associated parameter of the preset data frame conversion rule. If it is a positive overrun, the upper limit value of the constraint range is expanded according to the proportion of the overrun amplitude value. If it is a negative overrun, the lower limit value of the constraint range is expanded according to the proportion of the overrun amplitude value. Secondly, the expansion ratio is dynamically adjusted based on the sensitivity index of the protocol conversion group. The higher the sensitivity, the smaller the expansion ratio.
[0122] Step 533: Perform conflict detection on the preliminary expanded constraint range to generate a compliant expanded constraint range, so that the upper limit value of the preliminary expanded constraint range for positive overrun is truncated to the upper limit value of the impedance constraint interval, and the lower limit value of the preliminary expanded constraint range for negative overrun is raised to the lower limit value of the impedance constraint interval.
[0123] In this step, the conflict detection operation refers to the process of checking whether the expanded constraint range conflicts with the constraint ranges of other fields and correcting the conflict interval.
[0124] In an embodiment of the present invention, first perform a conflict detection operation on the preliminary expanded constraint range to detect whether the expanded upper limit value exceeds the upper limit of the original impedance constraint interval of the corresponding protocol conversion group. If it exceeds, truncate the upper limit value to the upper limit of the original impedance constraint interval to generate a positive compliant expansion range. Subsequently, detect whether the expanded lower limit value is lower than the lower limit of the original impedance constraint interval. If it is lower, raise the lower limit value to the lower limit of the original impedance constraint interval. Finally, generate a negative compliant expansion range.
[0125] Step 534: Perform directional fusion of the compliant expanded constraint range and the associated parameter of the preset data frame conversion rule to generate an updated associated parameter.
[0126] In this step, the compliant expanded constraint range refers to the constraint range corrected by conflict detection, ensuring no overlap with other constraint conditions and conforming to global restrictions. The directional fusion operation refers to the process of integrating the compliant expanded constraint range with the original constraint parameters, retaining the effective constraints and replacing the overrun part.
[0127] In an embodiment of the present invention, first perform a directional fusion operation on the compliant expanded constraint range and the associated parameter of the preset data frame conversion rule, retaining the range of the non-overrun fields in the original constraint parameters. Subsequently, replace the constraint range of the overrun fields with the compliant expanded constraint range. Finally, generate an updated associated parameter containing the dynamically adjusted constraint conditions.
[0128] In the embodiments of the present invention, by dynamically identifying the overrun direction and amplitude, the precise expansion of the constraint range is realized, solving the problem of frequent data overruns caused by the static range in the traditional solution; the conflict detection and compliance correction mechanism ensures the global compatibility of the expanded constraint range, avoiding multi-field constraint conflicts; the directional fusion ensures the integrity of key data, significantly improving the reliability and environmental adaptability of protocol conversion.
