The present invention realizes the acquisition of plume data of an on-orbit engine in a real high vacuum environment. The invention has the following problems:

[0004] The invention does not consider the problem of how to know if the engine has undergone abnormal operation that is not officially recognized and how to obtain accurate engine data. Summary of the invention

[0005] To this end, the present invention provides a data acquisition method and system based on identification resolution to overcome the problem in the prior art of not knowing whether the engine has undergone abnormal operations that have not been officially recognized and whether the obtained engine data is authentic.

[0017] If the number of alarms is greater than the preset number, it is determined that the disassembly characterization state of the engine is abnormal disassembly.

[0018] Further, the content of the second parsed plaintext is determined according to the parsing level and the disassembly representation state, including:

[0019] If the parsing level and the disassembly representation state satisfy a comprehensive parsing condition, determining that the content of the second parsed plaintext includes the first parsed plaintext and the disassembly representation state;

[0020] If the parsing level and the disassembly representation state do not satisfy the comprehensive parsing condition, determining that the second parsed plaintext only includes the first parsed plaintext;

[0021] The comprehensive analysis condition is that the analysis level is greater than a preset level and the disassembly characterization state is that abnormal disassembly exists.

[0022] Further, according to the determination result of whether there is a marking record within the single exposure time, it is determined to send an alarm signal to the engine production terminal and update the historical alarm log, including:

[0023] If there is no marking record within the single exposure time, it is determined to send an alarm signal to the engine production terminal and update the historical alarm log.

[0024] On the other hand, the present invention also provides a data acquisition system based on identity resolution, comprising:

[0025] An exposure identification module, used to determine whether the identifier has been exposed and record historical exposure information, wherein the historical exposure information includes the number of exposures and the exposure start time and exposure end time of each exposure;

[0031] Furthermore, the identification scanning module includes:

[0032] An identification scanning unit for scanning the identifier inside the engine;

[0033] a marking execution unit, which is disposed inside the identification scanning module and connected to the identification scanning unit, and is used to mark the identifier inside the engine;

[0034] A marking recording unit is arranged inside the identification scanning module and connected to the marking execution unit. The marking recording unit records the marking information of each marking and updates the historical marking information according to the marking information.

[0035] Furthermore, the exposure identification module includes:

[0036] A light sensor for determining light data of the position of the identifier;

[0037] A controller connected to the light sensor, configured to determine whether the identifier is exposed according to the light data and control the start and end of the timer;

[0038] A timer is connected to the controller and is used to record the exposure start time and the exposure end time.

[0039] Furthermore, the controller controls the start and end of the timer according to the change value of the light data, wherein:

[0040] If the change value of the light data is greater than the absolute value of the preset threshold, the timer is controlled to start timing;

[0041] If the change value of the light data is less than a preset threshold, the timer is controlled to end timing;

[0042] The change value of the light data is the difference between the light data at the current moment and the light data at the adjacent previous moment, and the preset threshold is a negative value.

[0043] Furthermore, the exposure start time and the exposure end time are respectively the times corresponding to the start and end of timing of the timer controlled by the controller.

[0044] Compared with the prior art, the beneficial effect of the present invention is that the data acquisition method based on identification resolution provided by the present invention is combined with the identity information verification of the sending and receiving modules and the subsequent resolution level determination, which can ensure the accuracy and security of the data acquisition process and effectively prevent the data from being accessed or tampered with without authorization; the disassembly characterization state of the engine is determined by the historical alarm log, and it can comprehensively evaluate whether the engine has illegal modification / operation / failure, which helps to timely discover potential problems and provide strong support for subsequent maintenance decisions; the operation after each disassembly of the engine is recorded in detail in the historical disassembly log, which helps to track the maintenance history of the engine and optimize the maintenance process. At the same time, the complete maintenance record also provides an important basis for subsequent quality tracing and performance analysis; the entire data acquisition method integrates advanced technologies such as the Internet of Things, identification resolution, and big data analysis, and realizes the digitization and intelligence of engine maintenance management. This not only improves work efficiency, but also reduces the risk of human error, and provides strong support for the transformation of enterprises to intelligent manufacturing.

[0045] Furthermore, by introducing the scanning end identity level library and the resolution identity level library and determining the resolution level accordingly, refined control of the identifier resolution process is achieved: the hierarchy and security of data access are ensured, that is, different identity levels correspond to first resolution plaintexts of different degrees of detail, which effectively prevents the leakage of sensitive information; at the same time, the two level libraries are uniformly managed and updated by the engine manufacturer, ensuring the authority and consistency of identity levels and resolution permissions; in addition, the resolution level is flexibly determined according to the actual identities of the scanning end and the resolution end, which not only ensures full data sharing, but also avoids unnecessary abuse of permissions; finally, the resolution plaintext content at each level formulated by the manufacturer ensures the accuracy and pertinence of the information, and provides strong support for subsequent maintenance decisions; this method of determining the first resolution plaintext content by determining the resolution level improves the efficiency, security and flexibility of data acquisition and processing.

[0046] Furthermore, by setting a strict preset number of times as a benchmark for judging the engine disassembly status, the illegal or private disassembly of the engine can be effectively avoided. Since the engine is the core power source, the stability of its performance and status is crucial to the operation of the entire mechanical equipment. Any unauthorized disassembly may cause irreversible damage to the engine, thereby affecting the operating efficiency and safety of the entire equipment. Therefore, this method obtains and analyzes historical alarm logs. Once any alarm record is found, it is determined that the engine is in an abnormal disassembly state.

[0047] Furthermore, by comparing the light data change value with the preset threshold, the subtle changes in the light environment during the engine disassembly process can be accurately captured, thereby achieving precise start and stop control of the timer, that is, achieving accurate judgment on whether the engine is disassembled; this high-precision time control provides a solid foundation for subsequent engine status analysis, abnormality detection and alarm mechanism, ensuring the efficiency and accuracy of engine maintenance management.

[0056] See also Figure 1 and Figure 2 As shown, they are respectively a step diagram of a data acquisition method based on identity resolution according to an embodiment of the present invention and a flow chart of a data acquisition method based on identity resolution according to an embodiment of the present invention. An embodiment of the present invention provides a data acquisition method based on identity resolution, comprising:

[0057] Step S1, disassembling the engine and scanning the identifier inside it;

[0058] Step S2, the resolution sending module sends the identification resolution request and the scanning end identity information, and the resolution receiving module inputs the resolution identity information;

[0059] Step S3, in response to the identification resolution request, the identification resolution module determines a resolution level according to the scanning end identity information and the resolution identity information to resolve the identifier to obtain a corresponding first resolution plaintext;

[0060] Step S4, the identification resolution module obtains the historical alarm log in the identification alarm module and determines the disassembly characterization state of the engine according to the number of alarms;

[0061] Step S5, the identification resolution module determines and outputs the content of the second resolution plaintext to the resolution receiving module according to the resolution level and the disassembly representation state;

[0062] Step S6, writing the operations performed on the engine after the current disassembly of the engine into the historical disassembly log, marking the identifier and updating the historical marking information, wherein the historical marking information includes the marking time of each marking and the historical disassembly log of the engine corresponding to each marking;

[0063] Step S7, assembling the engine, the identification alarm module obtains historical exposure information and historical marking information, and determines to send an alarm signal to the engine production terminal and update the historical alarm log according to the determination result of whether there is a marking record within a single exposure time.

[0064] It is understandable that the data acquisition method based on identification resolution provided by the present invention, combined with the identity information verification of the sending and receiving modules and the subsequent resolution level determination, can ensure the accuracy and security of the data acquisition process and effectively prevent the data from being accessed or tampered with without authorization; the disassembly characterization status of the engine is determined by the historical alarm log, and it can comprehensively evaluate whether the engine has illegal modification / operation / failure, which helps to timely discover potential problems and provide strong support for subsequent maintenance decisions; the operation after each disassembly of the engine is recorded in detail in the historical disassembly log, which helps to track the maintenance history of the engine and optimize the maintenance process. At the same time, the complete maintenance record also provides an important basis for subsequent quality tracing and performance analysis; the entire data acquisition method integrates advanced technologies such as the Internet of Things, identification resolution, and big data analysis, and realizes the digitization and intelligence of engine maintenance management. This not only improves work efficiency, but also reduces the risk of human error, and provides strong support for the transformation of enterprises to intelligent manufacturing.

[0065] Specifically, in step S3, the scanning end identity information and the parsing identity information respectively determine the corresponding scanning end identity level and parsing identity level according to the scanning end identity level library and the parsing identity level library, and determine the parsing level according to the scanning end identity level and the parsing identity level to parse the identifier to obtain the corresponding first parsed plaintext;

[0066] The parsing level is positively correlated with the detail of the corresponding first parsed plaintext, that is, the higher the parsing level, the more detailed the content of the first parsed plaintext.

[0067] It can be understood that the level technology in the scanning end identity level library and the level number in the parsing identity level library are equal to the level of the parsing level. The higher the level number, the higher the corresponding identity level.

[0068] In implementation, both the scanner identity level library and the resolution identity level library are pre-stored in the identification resolution module and are only updated by the engine manufacturer;

[0069] In the implementation, in the scanner identity level library: the scanner identity level of repair shops without official authorization is 1, the scanner identity level of officially authorized repair points is usually 2 (a small number of specially authorized repair points are 3), and the scanner identity level of the official directly-operated 4S shop after-sales service is 3;

[0070] In practice, in the resolution identity level database, the resolution identity level of maintenance personnel without official authorization is 1, the resolution identity level of maintenance personnel authorized by the government is usually 2 (some maintenance personnel with special authorization are 3), and the resolution identity level of official maintenance personnel on duty is 3;

[0071] In implementation, the resolution level is the lower one between the scanning end identity level and the resolution identity level, that is, if the scanning end identity level is less than the resolution identity level, the resolution level is the scanning end identity level; if the scanning end identity level is greater than the resolution identity level, the resolution level is the resolution identity level.

[0072] In implementation, the content of the first parsed plaintext corresponding to each level in the parsing level is determined by the manufacturer.

[0073] It can be understood that by introducing the scanning end identity level library and the resolution identity level library, and determining the resolution level accordingly, refined control of the identifier resolution process is achieved: the hierarchy and security of data access are ensured, that is, different identity levels correspond to first-resolution plaintexts of different degrees of detail, which effectively prevents the leakage of sensitive information; at the same time, the two level libraries are uniformly managed and updated by the engine manufacturer, ensuring the authority and consistency of identity levels and resolution permissions; in addition, the resolution level is flexibly determined according to the actual identity of the scanning end and the resolution end, which not only ensures full data sharing, but also avoids unnecessary abuse of permissions; finally, the resolution plaintext content at each level formulated by the manufacturer ensures the accuracy and pertinence of the information, and provides strong support for subsequent maintenance decisions; this method of determining the first-resolution plaintext content by determining the resolution level improves the efficiency, security and flexibility of data acquisition and processing.

[0074] Specifically, in step S4, the historical alarm log is obtained and the disassembly characterization state of the engine is determined according to the number of alarms, including:

[0075] If the number of alarms is greater than the preset number, it is determined that the disassembly representation state of the engine is abnormal disassembly;

[0076] If the number of alarms is less than or equal to the preset number, it is determined that the disassembly characterization state of the engine is no abnormal disassembly.

[0077] It is understandable that the engine is the core power source of many mechanical equipment (such as automobiles, airplanes, ships, generators, etc.). It generates power by burning fuel or other forms of energy to drive the operation of the equipment. As a power source, the performance and status of the engine directly affect the operating efficiency and stability of the entire equipment; it is one of the most complex and technologically advanced components in mechanical equipment, and it is also the part with high manufacturing and maintenance costs. Therefore, the engine should not be disassembled illegally / disassembled privately, so in implementation, the preset number is 0, that is, if the number of alarms is greater than 0, it means that the engine may be disassembled privately, and the performance and stability of the engine cannot be guaranteed.

[0078] It is understandable that by setting a strict preset number of times as a benchmark for judging the engine disassembly status, illegal or private disassembly of the engine can be effectively avoided. Since the engine is the core power source, the stability of its performance and status is crucial to the operation of the entire mechanical equipment. Any unauthorized disassembly may cause irreversible damage to the engine, thereby affecting the operating efficiency and safety of the entire equipment. Therefore, this method obtains and analyzes historical alarm logs, and once any alarm record is found, it is determined that the engine is in an abnormal disassembly state.

[0079] Specifically, in step S5, the content of the second parsed plaintext is determined according to the parsing level and the disassembly representation state, including:

[0080] If the parsing level and the disassembly representation state satisfy a comprehensive parsing condition, determining that the content of the second parsed plaintext includes the first parsed plaintext and the disassembly representation state;

[0081] If the parsing level and the disassembly representation state do not satisfy the comprehensive parsing condition, determining that the second parsed plaintext only includes the first parsed plaintext;

[0082] The comprehensive analysis condition is that the analysis level is greater than a preset level and the disassembly characterization state is that abnormal disassembly exists.

[0083] In implementation, the preset level is Level 1, that is, it is necessary to have both the officially authorized scanning end identity level and the parsing identity level; it is understandable that when the disassembly representation state is no abnormal disassembly, it is not necessary to add the disassembly representation state to the second parsing plaintext under any circumstances; and when the disassembly representation state is abnormal disassembly, it is necessary to have both the officially authorized scanning end identity level and the parsing identity level to display the disassembly representation state to it, so as to improve the security of the data and avoid the risk of data modification, especially to avoid tampering with the data after irregular modification of the engine.

[0084] It can be understood that by comprehensively considering the parsing level and the disassembly representation status to determine the content of the second parsed plaintext, the data security and information transparency are effectively balanced; when the disassembly representation status is normal, the second parsed plaintext does not contain the content of the disassembly representation status, avoiding unnecessary information disclosure and reducing data redundancy; and when abnormal disassembly is found, the disassembly representation status is only displayed when the parsing level meets the official authorization conditions, which not only enhances the confidentiality of the data, but also prevents the risks of illegal modification and data tampering, ensuring the authenticity and credibility of the data; this flexible and rigorous data processing mechanism is of great significance for maintaining the integrity and safety of the engine and its mechanical equipment.

[0085] Specifically, in step S7, according to the determination result of whether there is a marking record within the single exposure time, it is determined whether to send an alarm signal to the engine production terminal and update the historical alarm log, including:

[0086] If there is a marking record within the single exposure time, it is determined that no alarm signal will be sent to the engine production terminal and the historical alarm log will not be updated;

[0087] If there is no marking record within the single exposure time, it is determined to send an alarm signal to the engine production terminal and update the historical alarm log.

[0088] It can be understood that after the engine is disassembled, the exposure identification module controls the start and end of the timer, and the timer sets the start time and the end time as the exposure start time and the exposure end time of the current exposure, respectively, and determines the exposure duration period of the current exposure by the exposure start time and the exposure end time; when scanning the identifier, it will be marked and recorded in the historical marking information, and the historical marking information includes the marking time of each marking and the engine historical disassembly log corresponding to each marking; therefore, by determining whether the last marking time is within the exposure duration period of the current exposure, it can be determined whether there is a marking record within the single exposure duration.

[0089] It is understandable that if a marking record is detected during a single exposure period, it indicates that the engine status has been officially recognized or maintained normally, thus avoiding unnecessary alarm signal sending and log updates, reducing false alarms and redundant processing. On the contrary, if there is no marking record during the exposure period, it may be normal maintenance that is not officially recognized or the engine is not closed tightly (loose) and a fault occurs, then the alarm mechanism is automatically triggered and a signal is sent to the engine production terminal, and the historical alarm log is updated, ensuring that the manufacturer can respond and handle abnormal situations quickly; while optimizing the monitoring process, it also improves the efficiency and safety of engine maintenance management.

[0090] See also Figure 3As shown, it is a connection diagram of a data acquisition system based on identity resolution according to an embodiment of the present invention. An embodiment of the present invention also provides a data acquisition system based on identity resolution, including:

[0091] An exposure identification module, used to determine whether the identifier has been exposed and record historical exposure information, wherein the historical exposure information includes the number of exposures and the exposure start time and exposure end time of each exposure, and is connected to the identifier in implementation;

[0092] An identification scanning module, used to scan the identifier inside the engine, mark the identifier once and update the historical marking information, wherein the historical marking information includes the marking time of each marking and the historical engine disassembly log corresponding to each marking;

[0093] A resolution sending module, which is connected to the identification scanning module and is used to send an identification resolution request and scanning end identity information to the identification resolution module after scanning the identifier;

[0094] An identification alarm module, which is connected to the exposure recognition module and the identification scanning module respectively, and is used to obtain historical alarm logs and historical marking information, and determine whether to send an alarm signal to the engine production terminal and update the historical alarm log according to the result of the determination whether there is a marking record within a single exposure time. The historical alarm log includes the number of alarms and the historical alarm time;

[0095] an identification resolution module, which is respectively connected to the resolution sending module, the identification warning module and the resolution receiving module, and is used to obtain the identification resolution request and the scanning end identity information, determine the resolution level according to the scanning end identity information and the resolution identity information, resolve the identifier according to the resolution level to obtain the corresponding first resolution plaintext, determine the disassembly representation state of the engine according to the number of warnings, and determine the content of the second resolution plaintext according to the resolution level and the disassembly representation state;

[0096] A parsing receiving module is connected to the identification parsing module and is used to input parsing identity information and obtain a second parsed plain text.

[0097] Specifically, the identification scanning module includes:

[0098] The identification scanning unit is used to scan the identifier inside the engine; it can be understood that the scanner for scanning the trademark identifier / identification code and its structure are both existing technologies, so they will not be described in detail;

[0099] a marking execution unit, which is disposed inside the identification scanning module and connected to the identification scanning unit, and is used to mark the identifier inside the engine;

[0100] A marking recording unit is arranged inside the identification scanning module and connected to the marking execution unit. The marking recording unit records the marking information of each marking and updates the historical marking information according to the marking information.

[0101] It is understood that the marking methods in the prior art include: (1) laser marking, which uses a laser beam to remove material from the surface of the identifier to form a permanent mark; (2) CNC engraving, which uses computer numerical control machinery to engrave and form a durable and wear-resistant mark; (3) silk screen printing, which uses screen printing technology to form patterns or text on the surface of parts; (4) inkjet marking, which uses an inkjet print head to mark directly on the part, but may not be a permanent mark; (5) electrochemical marking, which uses an electrochemical reaction to form a high-contrast black mark on the metal part.

[0102] In implementation, a simple and permanent marking method should be selected, usually laser marking, so the corresponding marking execution unit is a laser beam emitter.

[0103] Specifically, the identification alarm module determines whether there is a marking record within a single exposure time and satisfies the alarm condition to send an alarm signal to the engine production terminal and update the historical alarm log;

[0104] When the result of determining whether there is a marking record within the single exposure time does not meet the alarm condition, the marking alarm module does not send an alarm signal to the engine production terminal and does not update the historical alarm log;

[0105] The alarm condition is that there is no single marking record within the single exposure time.

[0106] See also Figure 4 As shown, it is a flowchart of the exposure recognition module of an embodiment of the present invention. Specifically, the exposure recognition module includes:

[0107] A light sensor, used to determine light data (in implementation, the light data is mostly light intensity) at the location of the identifier; it is understood that the light sensor is a digital light intensity sensor integrated circuit that can directly output a numerical value of ambient light intensity (in the range of 0lx to 65535lx), which is very suitable for measuring light intensity;

[0108] A controller connected to the light sensor, configured to determine whether the identifier is exposed according to the light data and control the start and end of the timer;

[0109] A timer is connected to the controller and is used to record the exposure start time (i.e., the timing start time) and the exposure end time (i.e., the timing end time).

[0110] Specifically, the controller controls the start and end of the timer according to the change value of the light data, wherein:

[0111] If the change value of the light data is greater than the absolute value of the preset threshold, the timer is controlled to start timing;

[0112] If the change value of the light data is less than a preset threshold, the timer is controlled to end timing;

[0113] The change value of the light data is the difference between the light data at the current moment and the light data at the adjacent previous moment, and the preset threshold is a negative value.

[0114] In practice, the engine is a key component, and the closer the preset threshold is to 0, the more precise the judgment of exposure is. Therefore, the preset threshold is usually -10lx to 0lx, preferably -5lx, where lx is the unit of light intensity, lux.

[0115] It can be understood that by comparing the change value of light data with the preset threshold, the subtle changes in the light environment during the engine disassembly process can be accurately captured, thereby realizing precise start and stop control of the timer, that is, realizing accurate judgment on whether the engine is disassembled; this high-precision time control provides a solid foundation for subsequent engine status analysis, abnormality detection and alarm mechanism, ensuring the efficiency and accuracy of engine maintenance management.

[0116] Specifically, the exposure start time and the exposure end time are respectively the times corresponding to the start and end of timing of the timer controlled by the controller.

[0117] It is understandable that the light sensor, controller and timer in the present invention are all in the prior art, so they are not described in detail.
