Description

Technical Field

[0001] This invention relates to the field of health management technology for wheeled special vehicles, and more specifically to an information interaction and health management system for wheeled special vehicles. Background Technology

[0002] As a crucial vehicle for realizing health management technology for wheeled special vehicles, the deployment and application of health management systems significantly improve the accuracy of fault diagnosis, scientifically provide triggering criteria for maintenance and support work, rationally determine the content of maintenance and support work, and effectively support management personnel's decisions on the deployment of special vehicles. Considering these combined effects, the application value of health management systems is not only reflected in the field of maintenance and support but also in assisting operational decision-making. Therefore, health management systems for wheeled special vehicles have become an important tool for achieving intelligent operation and maintenance goals in wheeled special vehicle equipment systems, and are gradually becoming an objective necessity for wheeled special vehicles to achieve condition-based maintenance and support.

[0003] To achieve these goals, the new generation of wheeled special vehicles not only equips each key subsystem and component with basic fault diagnosis and in-machine self-test modules, but also designs a health management system at the vehicle level that includes functions such as fault diagnosis and condition assessment. Due to a lack of unified design planning, these health management systems or modules suffer from significant functional redundancy, resulting in a serious waste of computing resources for wheeled special vehicles. Furthermore, the execution logic at the functional level has not been effectively integrated, leading to self-contradictory and repetitive analytical conclusions from these health management systems or modules. This hinders the effective integration of health management technology with maintenance and support work, thus severely diminishing the application value of the health management system.

[0004] Therefore, proposing a functionally integrated module with health management function in various subsystems and components, as well as a vehicle-level health management system, is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, the present invention provides an information interaction and health management system for wheeled special vehicles, which effectively integrates modules with health management functions in various subsystems and components and a vehicle-level health management system at the functional level, significantly reducing the computational burden of applying health management technology to wheeled special vehicles.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] This invention provides an information interaction and health management system for wheeled special vehicles, including multiple information interaction modules and a vehicle-level health management system;

[0008] The health management system includes a data communication module, a status assessment module, a fault diagnosis module, and a maintenance suggestion push module;

[0009] Multiple of the aforementioned information interaction modules are deployed in the corresponding structures of wheeled special vehicles;

[0010] The status assessment module, fault diagnosis module, and maintenance suggestion push module are all connected to multiple information interaction modules and are also connected to the data communication module; the data communication module is used to receive external user operation commands.

[0011] The status assessment module, fault diagnosis module, and / or maintenance suggestion push module query the corresponding information interaction module according to the operation instructions and return the query results; the query results include the status assessment, fault diagnosis, and maintenance suggestions of the corresponding vehicle structure.

[0012] Furthermore, the status assessment module, fault diagnosis module, and maintenance suggestion push module are all composed of three parts: a query submodule, a knowledge engine, and a reasoning submodule.

[0013] The data communication module sends a service query request to the query submodule of the status assessment module, fault diagnosis module, or maintenance suggestion push module according to the type of operation service corresponding to the operation instruction.

[0014] Furthermore, the business query request includes a query object code and a query information type code;

[0015] The query object code is used to identify the constituent objects of the wheeled special vehicle targeted by the query operation;

[0016] The query information type code is used to determine the business type corresponding to the query request.

[0017] Furthermore, the knowledge engine is composed of different mapping relationships, and each mapping relationship consists of three parts: mapping relationship encoding, domain, and value range.

[0018] The mapping relationship encoding consists of two encoding segments: the first segment is the query object encoding, and the second segment is the mapping relationship sequence number.

[0019] The domain is an information-encoded tuple containing one or more information codes;

[0020] The value range consists of an information encoding tuple containing one information encoding.

[0021] After receiving the query object code forwarded by the query submodule, the knowledge engine will filter all mapping relationships whose front-end code is the same as the query object code, and send all the filtered mapping relationships to the reasoning submodule.

[0022] Furthermore, the information encoding consists of four parts: information encoding type, attribution, sequence number, and value;

[0023] The information coding type is used to distinguish the type of the target information coding, including health status information coding, fault information coding, abnormal phenomenon information coding and maintenance suggestion information coding;

[0024] The attribution is used to indicate the constituent objects of the wheeled special vehicles to which the target information encoding belongs;

[0025] The serial number is used to distinguish target information codes of the same type and belonging to the same category, and is determined sequentially.

[0026] The value is used to describe the conclusion content of the target information encoding.

[0027] Furthermore, the reasoning submodule is used to extract all the domains of the obtained mapping relationship after obtaining the mapping relationship sent by the knowledge engine, perform a union operation on the extracted domains, and perform a deduplication operation to finally form a set composed of different information codes, and then set the value of each information code in the new set to null.

[0028] Finally, each piece of information in the new set is encoded, and the information encoding is distributed to the corresponding information interaction module according to the query object encoding in the information encoding.

[0029] Furthermore, the reasoning submodule is also used to activate the information encoding type, attribution, sequence number and value of the mapping relationship definition domain received by the reasoning submodule after receiving the new information encoding returned by the information interaction module;

[0030] If the information encoding type, attribution, sequence number, and value in the defined domain are all active, the value domain of the mapping relationship is sent to the data communication module; otherwise, the inactive information encoding is sent to the data communication module to generate a new business query request.

[0031] Furthermore, after receiving the information code sent by the reasoning submodule, the information interaction module will execute the corresponding query function according to the type of the information code, assign the query result to the value content of the information code, and finally return the assigned new information code to the corresponding reasoning submodule.

[0032] As can be seen from the above technical solution, compared with the prior art, the present invention discloses an information interaction and health management system for wheeled special vehicles. Through the question-and-answer information interaction mechanism between the whole vehicle-level health management system and the health management module built into the vehicle components, the collection of health management business conclusion evidence is completed, and the effective integration of the execution logic of the whole vehicle-level health management system and the subsystem health management module at the functional level is realized.

[0033] Meanwhile, the heavy data analysis and calculation are distributed to the health management module of vehicle components, realizing the unification of computing resources and computing data, and reducing the communication burden caused by sending computing data to the whole vehicle-level health management system. Attached Figure Description

[0034] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on the provided drawings without creative effort.

[0035] Figure 1 This is an architecture diagram of an information interaction and health management system for wheeled special vehicles provided in an embodiment of the present invention. Detailed Implementation

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] This invention discloses an information interaction and health management system for wheeled special vehicles, referring to... Figure 1 As shown, it includes multiple information interaction modules and a vehicle-level health management system;

[0038] The health management system includes a data communication module, a status assessment module, a fault diagnosis module, and a maintenance suggestion push module;

[0039] Multiple of the aforementioned information interaction modules are deployed in the corresponding structures of wheeled special vehicles;

[0040] The status assessment module, fault diagnosis module, and maintenance suggestion push module are all connected to multiple information interaction modules and are also connected to the data communication module; the data communication module is used to receive external user operation commands.

[0041] The status assessment module, fault diagnosis module, and / or maintenance suggestion push module query the corresponding information interaction module according to the operation instructions and return the query results; the query results include the status assessment, fault diagnosis, and maintenance suggestions of the corresponding vehicle structure.

[0042] The information interaction module is deployed in the control system or control box of the key component subsystem or part of the wheeled special vehicle. It works in the form of a software module and has data communication function, status assessment query function, anomaly detection query function and fault diagnosis query function.

[0043] The vehicle-level health management system's status assessment module, fault diagnosis module, and maintenance suggestion push module are all composed of three parts: a query submodule, a knowledge engine, and an inference submodule.

[0044] In this embodiment, after the system user issues an operation command, the data communication module of the vehicle-level health management system will send a service query request to the status assessment module, fault diagnosis module, or maintenance suggestion push module of the vehicle-level health management system according to the type of operation service received.

[0045] The business query request in this embodiment consists of two parts: the query object code and the query information type code. The codes and their corresponding code contents are shown in Table 1 below:

[0046] Table 1

[0047]

[0048] The query object code is used to identify the constituent objects of the wheeled special vehicle targeted by the query operation; that is, 001 corresponds to the power system, 002 corresponds to the transmission system, 003 corresponds to the control system, etc.; the query information type code is used to determine the business type corresponding to the query request; that is, 01 corresponds to status assessment query information, 02 corresponds to fault diagnosis query information, and 03 corresponds to maintenance suggestion query information.

[0049] The query submodule directly breaks down the business query requests sent by the data communication module, encodes the query objects, and forwards them to the knowledge engine. This submodule plays a crucial role in the vehicle-level health management system, primarily responsible for parsing and processing business query requests from the data communication module and passing necessary information to the knowledge engine. The query submodule not only improves the system's response speed and efficiency but also enhances the relevance and accuracy of the conclusions, contributing to more scientific and rational health management decisions.

[0050] The knowledge engine of the vehicle-level health management system's status assessment module, fault diagnosis module, and maintenance suggestion push module consists of different mapping relationships. Each mapping relationship is composed of three parts: mapping relationship code, domain, and value domain.

[0051] The mapping relationship between the knowledge engines of each module is shown in Table 2 below:

[0052] Table 2

[0053]

[0054] The mapping relationship encoding consists of two segments: the first segment is the query object encoding, with the same content as the query object encoding; the second segment is the mapping relationship sequence number, with content increasing sequentially from 0001. Both the domain and the range are information encoding tuples, the difference being that the domain information encoding tuple contains one or more information codes, while the range information encoding tuple contains only one information code.

[0055] As a core component of the vehicle-level health management system, the knowledge engine not only manages and applies mapping relationships but also supports the system's efficient operation through precise logical deduction. It ensures that the system can make scientific and reasonable health management decisions based on the latest data, thereby improving the operational efficiency and reliability of wheeled special vehicles.

[0056] After receiving the query object code from the query submodule, the knowledge engine will filter out all mapping relationships whose front-end code is the same as the query object code, and send all the filtered mapping relationships to the inference submodule.

[0057] In the vehicle-level health management system, the reasoning submodule acts as a bridge connecting the knowledge engine and the information interaction modules of various subsystems. It is responsible for executing the specific logical deduction process and ensuring that the mapping relationship can be correctly activated based on the actual data.

[0058] In this embodiment, each information code consists of four parts: information code type, attribution, sequence number, and value. For example, in the health status information code "s0012-1-0", "s" represents the information code type, "0012" is the attribution part, "1" is the sequence number, and "0" is the value.

[0059] Information coding types can be divided into four main categories: health status information coding, fault information coding, abnormal phenomenon information coding, and maintenance suggestion information coding. The information coding type is used to distinguish the type of the target information coding, where "s" represents health status information coding, "ft" represents fault information coding, "ab" represents abnormal phenomenon information coding, and "ms" represents maintenance suggestion information coding; the attribution indicates the constituent objects of the wheeled special vehicles to which this information coding belongs, and its content is the same as the query object coding; the sequence number is used to distinguish information codings of the same type and attribution, and they can be determined sequentially; the value describes the conclusion of this information coding. In this embodiment, the value of the health status information coding can be "0", "1", or "2", representing normal, general abnormality, or serious abnormality, respectively; the value of the fault information coding can be "0" or "1", representing no fault or occurrence, respectively; the value of the abnormal phenomenon information coding can be "0" or "1", representing no abnormal phenomenon or occurrence, respectively; and the value of the maintenance suggestion information coding can be "0" or "1", representing push or no push, respectively.

[0060] In this embodiment, the reasoning submodules of the vehicle-level health management system's functional modules—namely, the status assessment module, fault diagnosis module, and maintenance suggestion push module—after obtaining the mapping relationship sent by the corresponding knowledge engine, extract all the domains of the obtained mapping relationship. They then perform a union operation on all extracted domains, along with deduplication, ultimately forming a set composed of different information codes. Next, they set the value of each information code in the new set to null. For example, if the original information code was "ab003-002-0", after setting it to null, the new information code will become "ab003-002-Null". Finally, each information code in the new set is distributed to the information interaction module of the corresponding subsystem or component based on the query object code it belongs to.

[0061] After receiving the information code sent by the inference submodule, the information interaction module of a subsystem or component will execute the corresponding query function according to the information code type. For example, "ab003-002-Null" will trigger the information interaction module deployed in the operating system to call the anomaly detection query function, thereby obtaining the query result returned by the operating system control unit. The query result will be assigned to the value of the information code. For example, if the query result shows that the anomaly exists, the information code will become "ab003-002-1"; otherwise, it will be "ab003-002-0". Finally, the newly assigned information code will be returned to the inference submodule of the corresponding functional module.

[0062] In this embodiment, after receiving a new information code from the information interaction module of a subsystem or component, the inference submodule activates the same information code in the mapping relationship definition domain previously received by the inference submodule. If all component information codes in the definition domain are activated, the value domain of the mapping relationship is sent to the data communication module of the vehicle-level health management system. The data communication module will use the information code dictionary to parse the mapping result and feed back the parsing result to the system user. The information code dictionary is shown in Table 3 below:

[0063] Table 3

[0064]

[0065] As a key logic processing unit in the vehicle-level health management system, the inference submodule not only promotes close collaboration between the knowledge engine and various subsystems, but also ensures that the system can make accurate status assessments, fault diagnoses, and maintenance recommendations based on the latest real-world data. Through precise logical derivation and continuous data verification, the inference submodule significantly improves the decision-making capabilities and response efficiency of the health management system, providing a solid guarantee for the intelligent operation and maintenance of wheeled special vehicles.

[0066] This system achieves effective coordination between the vehicle-level health management system and the information interaction modules of subsystems or components through a question-and-answer interactive mechanism, avoiding functional redundancy and improving the utilization of computing resources.

[0067] It provides accurate condition assessment and fault diagnosis information, which helps to take the right maintenance measures in a timely manner, reduces unplanned downtime, and improves vehicle availability.

[0068] This distributed data analysis tasks, reduced the workload of the vehicle-level health management system, lowered communication load, and enhanced system response speed.

[0069] It not only supports routine maintenance activities, but also provides a scientific basis for vehicle usage decisions in special missions, ensuring the reliability of vehicles at critical moments.
