Description

Technical Field

[0001] This invention relates to the field of filter technology, and in particular to a dual-marking dust filter for mining and its tracking system and method. Background Technology

[0002] Miners work in high-dust-concentration environments with long work cycles, requiring them to periodically replace dust filters to ensure effective respiratory protection. To improve filter traceability, current technologies typically involve attaching electronic tags or visual identification codes to the filters for identification and information recording.

[0003] However, in practical applications, relying solely on a single identifier or a simple dual identifier can achieve the basic identification function of the filter cartridge, but risks such as management disorder, data distortion, and identity replacement still exist in the entire life cycle management process.

[0004] Especially in scenarios where multiple stages such as distribution, use, recycling, and testing are carried out simultaneously, the lack of a unified identity consistency verification mechanism, state sequence control mechanism, and anomaly locking mechanism can easily lead to: replacement of filter cartridge identity, cross-person binding of filter cartridges, distribution of new filter cartridges before recycling, misalignment of testing data with actual users, and logical conflicts in the life cycle time sequence.

[0005] The aforementioned issues will directly affect the authenticity and continuity of individual miner exposure data, thereby affecting the accuracy of dust exposure risk assessment.

[0006] Therefore, how to build a tracking system with dual identity logical consistency verification, life cycle state sequence control and automatic anomaly locking capabilities without changing the basic physical structure of the filter element, so as to ensure that the filter element's identity cannot be tampered with, skipped, or mismatched throughout its entire service life, has become an urgent technical problem to be solved. Summary of the Invention

[0007] Given the lack of identity consistency in the aforementioned or existing technologies: existing technologies typically only read the identifier during the distribution stage, lacking further consistency verification during the recycling and testing stages, leading to the risk of single identifier replacement; uncontrollable lifecycle sequence: filter cartridges often rely solely on manual recording between distribution, recycling, and testing stages, lacking mandatory status sequence control, easily resulting in logical conflicts such as distribution before recycling or case closure before testing; inability to technically prevent abnormal behavior: for abnormal situations such as duplicate scanning, cross-person binding, or identifier conflicts, existing systems mostly handle them with prompts rather than establishing an automatic locking mechanism; lack of continuity guarantee for multi-cycle data: in the exposure assessment process, most are based only on single-cycle load data, without considering the issues of lifecycle integrity and continuous cycle trend changes, this invention is proposed.

[0008] Therefore, the purpose of this invention is to provide a dual-marking dust filter element for mining and its tracking system and method.

[0009] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0010] A dual-marking dust filter element for mining, comprising:

[0011] A filter element includes a filter element body and a protective edge disposed on the outer periphery of the filter element body;

[0012] The identification components include a visual identification mark disposed on the filter element body and an electronic identification unit disposed on the filter element body;

[0013] The visual identification mark is associated with the information stored in the electronic identification unit, and the two together constitute the unique identity mark of the filter body, which is used to identify and track the filter body.

[0014] As a preferred embodiment of the dual-marking dustproof filter element for mining of the present invention, the filter element further includes a support frame disposed between the edge of the filter element body and the inner circumferential surface of the protective edge, wherein the end surface of the protective edge protrudes from the surface of the filter element body.

[0015] As a preferred embodiment of the dual-marking dustproof filter element for mining of the present invention, the marking element further includes a second microporous membrane disposed on the surface of the filter element body and a first microporous membrane covering the electronic marking unit and the visual identification mark, wherein the outer edge of the first microporous membrane is located on the inner circumferential surface of the protective edge.

[0016] A dual-identification tracking system for mining dust filters includes:

[0017] The identification acquisition module is used to read information from the visual identification identifier and the electronic identification unit;

[0018] The consistency verification module is used to verify the consistency between the visual identification mark and the identity information stored in the electronic identification unit, and generate a unique tracking identity when the verification is successful.

[0019] The identity binding module is used to associate the unique tracking identity with the user's identity information and the distribution time of the filter element;

[0020] The lifecycle status management module is used to record and control the status transitions of the filter element during the distribution, use, recycling, and testing stages;

[0021] The anomaly detection module is used to identify repeated scanning, cross-person binding, identifier conflict, or lifecycle jump behavior, and triggers a technical blocking mechanism after identification;

[0022] The data storage module is used to store the operation records and timestamp information of each stage mentioned above, and to perform time sequence verification through the operation timestamps of each stage of the filter element to prevent logical conflicts such as the recycling time being earlier than the release time or the detection time being earlier than the recycling time.

[0023] As a preferred embodiment of the dual-identification mining dust filter tracking system of the present invention, the life cycle status management module presets multiple status nodes, including inventory status, bound status, in use status, recycled and awaiting inspection status, inspection completed status, and abnormal lock status, and only allows status transitions in a preset order.

[0024] As a preferred embodiment of the dual-identification mining dust filter tracking system of the present invention, the consistency verification module performs dual-identification consistency verification in both the filter element initialization stage and the recycling stage. When the verification fails, the filter element is marked as abnormally locked and its entry into the detection process is blocked.

[0025] A method for tracking dual-identified dust filter cartridges used in mining includes the following steps:

[0026] I. Initialization of filter element identity consistency:

[0027] Before the filter element enters the management process, the visual identification mark and electronic identification unit on it are read simultaneously, and the consistency of the two is verified. Only when the verification is consistent is a unique tracking identity generated and confirmed.

[0028] II. Tracking Identity Binding:

[0029] The unique tracking identity of the confirmed filter element is bound to the user's identity information and the distribution time, and recorded in the data storage module;

[0030] III. Lifecycle Status Marking:

[0031] During the distribution, use, recycling and testing of the filter element, the status of the filter element is marked in stages to form a complete life cycle record of the filter element;

[0032] IV. Filter Cartridge Recycling:

[0033] During the filter element recycling stage, the visual identification tag and electronic identification unit are read again and their consistency is verified with the tracking identity confirmed in step one.

[0034] When verification fails, it is marked as an abnormal state and subsequent detection-related processes are blocked;

[0035] Data entry and association operations are only permitted after the consistency check passes.

[0036] V. Data Recording:

[0037] Record the timestamps of each stage and store them in the data storage module.

[0038] As a preferred embodiment of the dual-identification mining dust filter tracking method of the present invention, when inconsistency in identification or abnormal behavior is detected at any stage, the status of the filter element is set to an abnormal lock state, and subsequent detection and distribution processes are blocked.

[0039] As a preferred embodiment of the dual-identification mining dust filter tracking method of the present invention, a dust exposure change trend model of the user is constructed based on the detection data and life cycle data of the filter element corresponding to the same user in multiple usage cycles, which is used to reflect the user's long-term exposure status.

[0040] As a preferred embodiment of the dual-identification mining dust filter tracking method of the present invention, the result of the dust exposure change trend model is used as the distribution control condition, and a new filter tracking identity is only allowed to be generated for the corresponding user when the preset requirements of complete recycling and data continuity are met.

[0041] The beneficial effects of the dual-identification mining dust filter element and its tracking system and method of the present invention are as follows: The present invention establishes a dual-identification consistency verification mechanism, a life cycle state machine control mechanism and an abnormal automatic locking mechanism, thereby constructing a filter element full life cycle tracking system based on logic control, which fundamentally improves the authenticity, continuity and controllability of filter element identity management;

[0042] Enhanced identity consistency security: By performing dual identifier consistency verification during both the initialization and recycling phases, the information of the visual identification identifier and the electronic identification unit is always consistent, effectively preventing the replacement or forgery of a single identifier;

[0043] Implement mandatory control over the lifecycle sequence: By pre-setting inventory status, bound status, in use status, recycled and awaiting inspection status, inspection completed status, and abnormal lock status, and only allowing transitions in the preset order, process jumps and human intervention are avoided;

[0044] Establish an automatic blocking mechanism for abnormalities: When duplicate scanning, cross-person binding, or identifier conflict is detected, the system automatically sets the filter cartridge status to an abnormal lock state, blocking subsequent testing and distribution processes, and enhancing the system's anti-cheating capabilities.

[0045] By taking lifecycle integrity as a prerequisite for the validity of the trend model, and only incorporating complete lifecycle data into dust exposure trend analysis, the accuracy of long-term exposure assessment is improved. The exposure trend model results and data integrity conditions are used as prerequisites for the release of new lifecycle filter cartridges, thus achieving true closed-loop control.

[0046] By establishing a dual-identification consistency control and lifecycle logic constraint system, the problems of filter element identity loss and data distortion are solved from the management logic level, significantly improving the reliability and technical security of tracking and management of mining dust filter elements.

Visual identification mark; 23. Electronic identification unit; 24. Second microporous membrane. Detailed Implementation

[0051] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0052] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0053] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0054] Example 1

[0055] Reference Figures 1 to 2 This is the first embodiment of the present invention, which provides a dual-identification dust filter element for mining, which can establish a unique, reliable and tamper-proof tracking identity, thereby laying the foundation for subsequent full life cycle tracking and control.

[0056] Specifically, the filter element 1 includes a filter element body 11 and a protective edge 13 disposed on the outer periphery of the filter element body 11. The filter element body 11 is a conventional structure mining dustproof filter element.

[0057] The identification component 2 includes a visual identification mark 22 disposed on the filter element body 11 and an electronic identification unit 23 disposed on the filter element body 11; wherein, the information stored in the visual identification mark 22 and the electronic identification unit 23 are interconnected, and the two together constitute a unique identification mark of the filter element body 11, which is used to identify and track the filter element body 11. Before the filter element 1 enters the use process, the uniqueness and authenticity of the filter element 1 are ensured by the consistency verification of the dual identification marks.

[0058] The filter element 1 also includes a support frame 12 disposed between the edge of the filter element body 11 and the inner circumferential surface of the protective edge 13. The end surface of the protective edge 13 protrudes from the surface of the filter element body 11. The marking element 2 also includes a second microporous membrane 24 disposed on the surface of the filter element body 11 and a first microporous membrane 21 covering the electronic marking unit 23 and the visual identification mark 22. The outer edge of the first microporous membrane 21 is located on the inner circumferential surface of the protective edge 13.

[0059] The protective edge 13 is made of highly elastic medical-grade silicone material, and its end surface is 1.0 mm higher than the surface of the filter body 11, so as to form a natural pressing area when installed on the filter body 11, preventing dust from leaking from the edge; the support frame 12 is a ring-shaped rigid frame, which is embedded in the edge area of ​​the filter body 11 to provide structural support, prevent the filter body 11 from collapsing during wear, and form a protective inner cavity.

[0060] Before each filter element 1 enters the warehousing or distribution management process, it is configured with two related but different forms of identification. One is a visual identification mark 22, such as a QR code, and the other is an electronic identification unit 23, such as a passive RFID tag or a passive NFC tag.

[0061] During the identity initialization stage of filter element 1, the information of visual identification mark 22 and electronic identification unit 23 are read simultaneously. Unlike the existing technology of "reading and recording separately", in this embodiment, a consistency verification process is first executed, that is, the core identity fields contained in the two marks are compared and judged. This consistency verification is not a simple numerical comparison, but can include a variety of verification methods, such as check code comparison, hash value comparison or preset mapping rule comparison.

[0062] Only when the system determines that the two identification information are logically completely consistent will it allow the generation of a unique tracking identifier for the filter element 1 and mark it as "initialization completed".

[0063] If inconsistencies are found between the two identification information during the initialization phase, the filter element will be marked as having an abnormal initialization state and will be prohibited from entering the subsequent distribution and binding process. At the same time, the cause of the abnormality, the time point, and the operation record will be recorded for subsequent management or auditing purposes.

[0064] After the consistency verification is passed, the filter element 1 identity binding stage begins. In this stage, the unique tracking identity of filter element 1 is bound to the identity information of the specific user and the distribution time, forming an unmodifiable binding record. The binding record remains valid throughout the entire filter element lifecycle, and any subsequent operations must be based on this binding relationship.

[0065] This embodiment can complete the identity trust control before the filter element 1 is put into use, thus technically avoiding the problems of filter element replacement, mixing or repeated binding.

[0066] Example 2

[0067] Reference Figures 1 to 2 This is the second embodiment of the present invention, which provides a dual-identification tracking system for mine dust filter cartridges, specifically including:

[0068] The identification acquisition module is used to read information from the visual identification tag 22 and the electronic identification unit 23;

[0069] The consistency verification module is used to verify the consistency between the visual identification tag 22 and the identity information stored in the electronic identification unit 23, and generate a unique tracking identity when the verification is successful.

[0070] The identity binding module is used to associate the unique tracking identity with the user's identity information and the distribution time of filter element 1;

[0071] The lifecycle status management module is used to record and control the status transitions of filter element 1 during the distribution, use, recycling, and testing stages;

[0072] The anomaly detection module is used to identify repeated scanning, cross-person binding, identifier conflict, or lifecycle jump behavior, and triggers a technical blocking mechanism after identification;

[0073] The data storage module is used to store the operation records and timestamp information of each stage mentioned above, and to perform time sequence verification through the operation timestamps of each stage of the filter element 1 to prevent logical conflicts such as the recycling time being earlier than the issuance time or the detection time being earlier than the recycling time.

[0074] The lifecycle status management module has multiple preset status nodes, including inventory status, bound status, in use status, recycled and awaiting inspection status, inspection completed status, and abnormal lock status, and only allows status transitions in a preset order.

[0075] The consistency verification module performs dual-identification consistency verification during both the initialization and recycling phases of filter element 1. When the verification fails, filter element 1 is marked as an abnormal locked state and its entry into the testing process is blocked.

[0076] When filter element 1 enters the system, the following process is executed:

[0077] I. Initialization Phase

[0078] Simultaneously read the visual identification tag 22 and the electronic identification unit 23. If the information of the two is inconsistent, it is directly marked as an abnormal lock state. If they are consistent, a unique tracking identity is generated.

[0079] II. State Definition

[0080] This embodiment predefines six state nodes and state transition rules, such as:

[0081] The inventory status is changed to the bound status, which requires performing double consistency verification;

[0082] The status has been changed from "bound" to "in use," and the start time of use must be recorded.

[0083] The process involves transitioning from the "in use" state to the "recycled and awaiting inspection" state, during which a recycling verification must be performed.

[0084] The status has been changed from pending detection to detection completed, during which detection data needs to be entered.

[0085] An abnormal state is detected at any stage, leading to an abnormal lockout state.

[0086] Among the requirements: skipping transformations is not allowed; reverse transformations are not allowed; and a timestamp must be included.

[0087] If you attempt to skip "Recycled and awaiting detection" and proceed directly to "Detection complete", the system will refuse.

[0088] III. Timestamp Logic Verification

[0089] The system simultaneously records: issuance time T1, usage start time T2, retrieval time T3, and detection time T4. The system automatically performs time sequence verification.

[0090] If T3 < T1, then an exception is triggered;

[0091] If T4 < T3, then the detection process is blocked.

[0092] IV. Anomaly Detection

[0093] This embodiment sets the following anomaly types: duplicate scanning, cross-person binding, state jump, and identity conflict. Once an anomaly is identified, the state immediately enters an anomaly lock state.

[0094] The advantage of this embodiment is that it replaces manual management with technical logic constraints to build an "unavoidable state machine control"; the technical effects are: to prevent manual pre-entry of test data, to prevent the direct distribution of new filter elements without recycling, and to prevent cross-cycle cheating.

[0095] The anomaly detection module includes: a duplicate scan detection submodule, a cross-person binding detection submodule, an identifier conflict detection submodule, and a state jump detection submodule. For example:

[0096] If the same tracking identity is bound to different miner accounts, a cross-person binding exception is triggered.

[0097] If multiple scan records are retrieved within the same time period, a duplicate scan exception is triggered.

[0098] Once an exception is triggered: the system immediately executes the following: the status changes to an exception lock state; subsequent detection associations are frozen; the operation device number is recorded; the operator account is recorded; and the exception type is recorded.

[0099] Abnormal data is compiled into an abnormal file.

[0100] The system supports anomaly classification: Level 1 anomaly (operational error), Level 2 anomaly (repeated anomaly), and Level 3 anomaly (suspected human substitution).

[0101] When a miner experiences two or more Level 2 anomalies within three cycles:

[0102] The system automatically marks it as a high-risk object, establishes a technical responsibility traceability chain, prevents filter replacement, prevents recycling on behalf of others, and forms an auditable data chain.

[0103] Example 3

[0104] Reference Figures 1 to 2 This is the third embodiment of the present invention, which provides a dual-identification mining dust filter tracking method, specifically including the following steps:

[0105] Filter element identity consistency initialization: Before filter element 1 enters the management process, the visual identification mark 22 and electronic identification unit 23 on it are read at the same time, and the consistency of the two is verified. Only when the verification is consistent, a unique tracking identity is generated and confirmed.

[0106] Tracking Identity Binding: The unique tracking identity of the confirmed filter element 1 is bound to the user's identity information and the distribution time, and recorded in the data storage module;

[0107] Lifecycle status marking: During the distribution, use, recycling and testing of filter element 1, the status of filter element 1 is marked in stages to form a complete lifecycle record of filter element 1;

[0108] Filter cartridge recycling: During the filter cartridge 1 recycling stage, the visual identification mark 22 and electronic identification unit 23 are read again and their consistency is verified with the tracking identity confirmed in step S1.

[0109] When verification fails, it is marked as an abnormal state and subsequent detection-related processes are blocked;

[0110] Data entry and association operations are only permitted after the consistency check passes.

[0111] Data recording: Records the timestamps of each stage and stores them in the data storage module.

[0112] If any inconsistent identification or abnormal behavior is detected at any stage, the status of filter element 1 will be set to abnormal lock state, and subsequent testing and distribution processes will be blocked.

[0113] Based on the detection data and life cycle data of the filter element 1 for the same user in multiple usage cycles, a dust exposure change trend model for the user is constructed to reflect their long-term exposure status.

[0114] Building a trend model:

[0115] Let the exposure value for the nth period be En: En = dust load ÷ usage time.

[0116] Introducing the data integrity coefficient K:

[0117] If the cycle integrity is satisfied: normal recovery, no abnormal locking, and valid time sequence.

[0118] If so, K=1; otherwise, K=0.

[0119] The trend model is: T(n) = Σ(En × K) ÷ number of effective periods.

[0120] The system performs trend analysis on T(n):

[0121] If the price rises for three consecutive cycles, the risk is considered to have increased.

[0122] If the situation remains stable, the existing protection level will be maintained.

[0123] If the temperature drops, it indicates that the protective measures are effective.

[0124] This trend result serves as the basis for determining the authority to grant permissions.

[0125] It reflects the risk of chronic exposure and prevents the randomness of single-period data from affecting the judgment.

[0126] The results of the dust exposure trend model are used as the distribution control condition. Only when the preset requirements for complete recycling and data continuity are met will it be allowed to generate a new filter tracking identity for the corresponding user.

[0127] Before the data is distributed, the system automatically determines whether the previous period's status is "detection completed," whether it is under anomaly lock, whether the data continuity requirements are met, and whether the trend model exceeds the preset threshold.

[0128] If any condition is not met, the system refuses to generate a new unique tracking identity.

[0129] Forced closed-loop system to prevent new items from being taken before they are recycled, and to prevent skipping the detection process.

[0130] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
