Description

Technical Field

[0001] This invention relates to the field of material quality sampling, sealing, and sample delivery management technology, specifically to a material quality sampling, sealing, and sample delivery management system. Background Technology

[0002] Material quality sampling and sealing management is a means to ensure the impartiality, authenticity and traceability of the quality inspection of purchased materials (such as power grid equipment). It covers the entire chain from sampling selection, on-site sealing, safe delivery of samples to laboratory sample receipt.

[0003] Physical sample identification tags often employ both QR codes and RFID (Radio Frequency Identification) electronic tags. Current technology uses self-adhesive "fragile paper" as the sealing material, partially obscuring sensitive information such as QR codes. However, this "fragile paper" sealing material is easy to forge and can be easily damaged and re-attached. Furthermore, current technology lacks devices to shield RFID electronic tags, making it susceptible to information leakage.

[0004] Therefore, how to prevent sample sealing from being forged and RFID electronic tag information from being leaked to a certain extent has become an urgent technical problem to be solved. Summary of the Invention

[0005] In view of this, in order to solve the above-mentioned technical problems, the present invention provides a material quality sampling and sealing management system.

[0006] The present invention adopts the following technical solution:

[0007] A material quality sampling and sealing management system includes: a cloud management platform, a mobile terminal, and a sealing device; The cloud management platform is used to create and send material management tasks to the mobile terminal, receive task execution result data uploaded by the mobile terminal, and generate abnormal alarm information. The mobile terminal is used to obtain the material management task from the cloud management platform, execute the material management task, and upload the task execution result data to the cloud management platform; The sealing device includes an RFID shielding tag and an equipment nameplate sealing box. The RFID shielding tag, through a multi-layer composite shielding structure, dynamic frequency filtering, and protocol-level collaborative design, covers the physical ID tag of the sample while shielding its original RFID tag information. The equipment nameplate sealing box is internally equipped with a first control module, a touch switch, and a first communication module. When the sealing cover of the equipment nameplate sealing box is manually removed or abnormally detached, the touch switch is activated and sends a touch signal to the first control module. The first control module generates a first alarm request based on the touch signal and sends the first alarm request to the cloud management platform through the first communication module. The cloud management platform generates an abnormal warning message for the equipment nameplate sealing box based on the first alarm request. The sealing cover is used to cover the nameplate of the sample.

[0008] Optionally, the multi-layer composite shielding structure includes an outer shielding structure and an inner shielding structure; The outer shielding structure is made of an iron-nickel alloy; The inner shielding structure is made of nano-carbon-based microwave absorbing material.

[0009] Optionally, the first communication module is a 4G LTE Cat1 communication module.

[0010] Optionally, the device nameplate sample box is further provided with a first storage device inside; The first control module is also used to generate and encrypt abnormal situation data of the device nameplate seal box when receiving the touch signal, and to store the encrypted abnormal situation data of the device nameplate seal box in the first storage device.

[0011] Optionally, this system may also include: a multi-state sensing sample in-transit monitoring device; The multi-state sensing sample in-transit monitoring device includes a second control module, a second communication module, an environmental sensing module, a positioning module, and an image acquisition module; The environmental sensing module collects environmental data during sample transportation at a first preset frequency and sends the environmental data to the second control module. When the second control module determines that the environmental data does not meet the preset environmental data requirements, it wakes up the image acquisition module, receives the first video data collected by the image acquisition module, analyzes the first video data, and obtains the first video data analysis result. When the first video data analysis result shows that there is an environmental anomaly, the second control module wakes up the second communication module and sends a second alarm request to the cloud management platform through the second communication module. The cloud management platform generates an environmental anomaly warning message for the in-transit monitoring device based on the second alarm request. The positioning module collects location data during sample transportation at a second preset frequency and sends the location data to the second control module. When the second control module determines that the location data does not meet the preset location data requirements, it wakes up the second communication module and sends a third alarm request to the cloud management platform through the second communication module. The cloud management platform generates an abnormal location warning message for the on-the-go monitoring device based on the third alarm request.

[0012] Optionally, the multi-state sensing sample in-transit monitoring device further includes: a human body detection sensor; When the human detection sensor detects a living entity activity signal within its monitoring area, it sends a hardware interrupt signal to the second control module. Upon receiving the hardware interrupt signal, the second control module wakes up the image acquisition module, receives the third video data acquired by the image acquisition module, and analyzes the third video data to determine whether there are any abnormal personnel within the monitoring area. If there are abnormal personnel within the monitoring area, the second control module wakes up the second communication module, which sends a fourth alarm request to the cloud management platform. The cloud management platform generates an abnormal personnel intrusion warning message for the on-transit monitoring device based on the fourth alarm request.

[0013] Optionally, the multi-state sensing sample in-transit monitoring device further includes: a second storage device; The second control module is also used to encrypt and store the relevant data of the abnormal environment to the second storage device when it is determined that there is an abnormal environment. The second control module is also used to encrypt and store the location data and related data to the second storage device when it is determined that the location data does not meet the preset location data requirements; The second control module is also used to encrypt and store the relevant data of the abnormal personnel in the second storage device when it is determined that there are abnormal personnel in the monitoring area.

[0014] Optionally, the positioning module includes a GPS positioning unit and a BeiDou positioning unit.

[0015] Optionally, this system may also include: a sampling device; The sampling device scans the sampling area by transmitting radio frequency signals through its radio frequency antenna array, receives response signals from the target sample, analyzes the response signals using an RSSI-based signal attenuation model, obtains the positioning result of the target sample, and dynamically adjusts the transmission power of the radio frequency antenna array according to the positioning result to achieve gradient scanning from the far field to the near field until the position of the target sample is determined.

[0016] Optionally, the expression for the signal attenuation model is as follows:

[0017] in, To be at a distance of the radio frequency antenna array Measured RSSI at the location To ensure that the distance to the radio frequency antenna array is a preset reference distance. The RSSI calibration at the location.

[0018] This invention employs the above technical solution to provide a material quality sampling and sealing management system, comprising: a cloud management platform, a mobile terminal, and a sealing device; the cloud management platform is used to create and send material management tasks to the mobile terminal, receive task execution result data uploaded by the mobile terminal, and generate abnormal alarm information; the mobile terminal is used to obtain material management tasks from the cloud management platform, execute the material management tasks, and upload task execution result data to the cloud management platform; the sealing device includes an RFID shielding tag and an equipment nameplate sealing box; the RFID shielding tag utilizes a multi-layer composite shielding structure, dynamic frequency filtering, and... The protocol-level collaborative design enables the physical ID tag of the sample to be covered while shielding its original RFID tag information. The equipment nameplate sealing box is internally equipped with a first control module, a touch switch, and a first communication module. When the sealing cover of the equipment nameplate sealing box is manually removed or abnormally detached, the touch switch is activated and sends a touch signal to the first control module. The first control module generates a first alarm request based on the touch signal and sends the first alarm request to the cloud management platform through the first communication module. The cloud management platform generates an abnormal warning message for the equipment nameplate sealing box based on the first alarm request. The sealing cover is used to cover the nameplate of the sample.

[0019] Based on this, since the RFID shielding tag adopts a multi-layer composite shielding structure, dynamic frequency filtering and protocol-level collaborative design to cover the physical ID tag of the sample and shield its original RFID tag information, this triple protection enables the present invention to effectively prevent the leakage of RFID electronic tag information. In addition, since the equipment nameplate sealing box is equipped with a first control module, a touch switch and a first communication module, a remote alarm is triggered when the sealing cover of the equipment nameplate sealing box is removed by human intervention or abnormally falls off, realizing real-time early warning of abnormal damage to the sample sealing. This enables the present invention to effectively prevent the sample sealing from being forged. Attached Figure Description

[0020] 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 some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0021] Figure 1 This is a schematic diagram of the structure of a material quality sampling and sealing management system provided in an embodiment of the present invention. Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0023] Figure 1 This is a schematic diagram of the structure of a material quality sampling and sealing management system provided in an embodiment of the present invention. Figure 1 As shown, this system includes: a cloud management platform 11, a mobile terminal 12, and a sealing device 13.

[0024] The cloud management platform 11 is used to create and send material management tasks to the mobile terminal 12, receive task execution result data uploaded by the mobile terminal 12, and generate abnormal alarm information. Material management tasks can be sealing tasks or testing tasks, etc.

[0025] The mobile terminal 12 is used to obtain material management tasks from the cloud management platform 11, execute the material management tasks, and upload the task execution result data to the cloud management platform 11.

[0026] The sample sealing device 13 includes an RFID shielding tag and a sample sealing box with an equipment nameplate. The RFID shielding tag supports the ISO 18000-6C standard, covering a frequency band of 800 to 1000 MHz, enabling compatibility with UHF RFID readers and systems. Through a multi-layered composite shielding structure, dynamic frequency filtering, and protocol-level collaborative design, the RFID shielding tag covers the physical ID tag of the sample and shields its original RFID tag information while ensuring standard compatibility. The RFID shielding tag features high shielding performance, wear resistance, vandal resistance, and reusability. It supports large-capacity information storage; the information can be stored on a local chip or remotely in the cloud. The RFID shielding tag can aggregate testing information such as sample sampling plan numbers, technical specifications, drawings, and testing items.

[0027] The multi-layer composite shielding structure includes an outer shielding layer and an inner shielding layer. The outer shielding layer is made of an iron-nickel alloy with high magnetic permeability, allowing it to directly reflect external radio frequency signals and prevent signal penetration. The inner shielding layer is made of nano-carbon-based absorbing material, enabling it to absorb residual electromagnetic waves not fully reflected by the outer layer. This dual mechanism of "reflection followed by absorption" achieves an extremely high shielding effectiveness of ≥55 dB @ 920MHz (20 dB higher than the ISO 18000-6C recommendation), far exceeding the protection level of ordinary commercial tags.

[0028] Dynamic frequency filtering refers to the ability of RFID shielding tags to dynamically adjust their filtering characteristics according to the operating frequency of the external RFID reader, in order to adapt to the RFID signal shielding requirements of different frequency bands (such as the UHF band 800 to 1000 MHz). Its specific implementation method is as follows: (1) Set up a tunable filter circuit: This circuit is used to shield the tunable LC filter or SAW filter integrated inside the tag, and automatically adjust the filter center frequency according to the detected external signal frequency.

[0029] (2) Use broadband absorbing materials combined with FSS (Frequency Selective Surface): Use composite materials with frequency selectivity to achieve efficient reflection or absorption in specific frequency bands (such as 920 MHz), while being transparent or having low loss in other frequency bands.

[0030] (3) Set up an adaptive impedance matching network: By dynamically adjusting the antenna impedance matching, the shielding tag can exhibit high reflection or absorption characteristics in a specific frequency band.

[0031] Protocol-level collaborative design refers to RFID shielding tags not only shielding physical signals but also interfering with or disguising the communication protocol, making it impossible for external readers to correctly identify or read the original RFID tag information of the physical ID tag. Its specific implementation is as follows: (1) Using protocol interference or spoofing responses: When an RFID shielded tag detects a query command from an external reader, it simulates an RFID tag response by sending interference data or error messages, preventing the reader from decoding it correctly.

[0032] Alternatively, a "silent" command (such as the Kill Command in ISO 18000-6C) can be sent directly to put the original RFID tag of the physical ID tag into a dormant state.

[0033] (2) Use encrypted or disguised IDs: RFID shielding tags can store a virtual ID, which is returned when the tag is read, instead of the original tag's real ID, thus achieving information hiding.

[0034] (3) Protocol layer collaborative shielding: The RFID shielding tag establishes a "pseudo-session" with the reader, occupying the communication channel and preventing the reader from establishing effective communication with the original tag.

[0035] The equipment nameplate sealing box internally houses a first control module, a push-to-open / release-to-close touch switch, and a first communication module. The touch switch is embedded within the sealing cover of the equipment nameplate sealing box and is mechanically linked to the sealing cover. When the sealing cover is properly installed, it presses against the touch switch, keeping the switch closed. When the sealing cover is manually removed or abnormally detached, the pressure is released, and the touch switch opens. Therefore, when the sealing cover is manually removed or abnormally detached, the touch switch is activated and sends a trigger signal to the first control module. The first control module generates a first alarm request based on the trigger signal and sends it to the cloud management platform 11 via the first communication module. The cloud management platform 11 then generates an abnormal warning message for the equipment nameplate sealing box based on the first alarm request. The sealing cover is used to cover the nameplate of the sample. Thus, the present invention can remotely alarm when the equipment nameplate seal box is deliberately damaged, thereby effectively preventing the equipment nameplate seal box from being counterfeited and improving the security of the nameplate.

[0036] In this embodiment of the invention, the first communication module can be a 4G LTE (Long Term Evolution) Cat1 (Category 1) communication module, which enables the invention to adapt to the low-speed, low-power transmission requirements of the Internet of Things.

[0037] In this embodiment of the invention, a first storage device is also provided inside the device nameplate sealing box. The first storage device can be a TF card.

[0038] The first control module is also used to generate and encrypt abnormal situation data of the equipment nameplate seal box when a trigger signal is received, and to store the encrypted abnormal situation data of the equipment nameplate seal box in the first storage device. In this way, encrypting the abnormal situation data of the equipment nameplate seal box can prevent the data from being tampered with or stolen. Secondly, by storing the data redundantly, data loss can be avoided in the event of network interruption.

[0039] In this embodiment of the invention, the material quality sampling and sealing management system may further include: a multi-state sensing sample in-transit monitoring device.

[0040] The multi-state sensing sample in-transit monitoring device includes a second control module, a second communication module, an environmental sensing module, a positioning module, and an image acquisition module. The second communication module can also be a 4G LTE Cat1 communication module.

[0041] The environmental sensing module may include a temperature sensor, a light sensor, and an acceleration sensor. The light sensor is located inside the multi-state sensing sample in-transit monitoring device and is used to detect changes in light intensity inside the device to determine whether the device has been turned on. The environmental sensing module collects environmental data during sample transportation at a first preset frequency. The duration of each data collection session can be the first preset duration, and the environmental data may include temperature, light intensity, and acceleration.

[0042] The environmental perception module sends environmental data to the second control module. The second control module determines whether the temperature, light intensity, and acceleration meet preset requirements. If any of these three conditions are not met, the second control module determines that the environmental data does not meet the preset environmental data requirements, and at this time, the second control module activates the image acquisition module.

[0043] After the image acquisition module is activated, it begins recording video and sends the first video data to the second control module. The second control module analyzes the first video data and obtains the analysis results. When the analysis results indicate an abnormal environmental situation (such as personnel tampering with the device), the second control module activates the second communication module and sends a second alarm request to the cloud management platform 11 through the second communication module. The cloud management platform 11 generates an environmental anomaly warning message for the on-the-go monitoring device based on the second alarm request.

[0044] The positioning module may include a GPS positioning unit and a Beidou positioning unit. The positioning module collects location data during sample transportation at a second preset frequency, with each data collection session lasting a second duration. The positioning module sends the location data to a second control module. The second control module generates a transportation trajectory for the sample based on all location data during this transportation process. It then determines whether the transportation trajectory conforms to a preset transportation trajectory. If not, the second control module determines that the location data does not meet the preset location data requirements. At this point, the second control module wakes up a second communication module, which sends a third alarm request to the cloud management platform 11. The cloud management platform 11 generates an abnormal location warning message for the on-the-go monitoring device based on the third alarm request.

[0045] In this embodiment of the invention, the multi-state sensing sample in-transit monitoring device may further include: a human body detection sensor. The human body detection sensor may be a passive infrared sensor.

[0046] When the human detection sensor detects a living entity activity signal within its monitoring area, it sends a hardware interrupt signal to the second control module. Upon receiving the hardware interrupt signal, the second control module wakes up the image acquisition module, receives the third video data acquired by the image acquisition module, and analyzes the human behavior in the third video data to determine whether there are any abnormal personnel within the monitoring area. In a specific example, if a person merely approaches the monitoring area and leaves without attempting to open the multi-mode sensing sample in-transit monitoring device, the person can be identified as a passerby. Conversely, if a person attempts to open the multi-mode sensing sample in-transit monitoring device, the person is identified as an abnormal personnel. When an abnormal personnel is detected within the monitoring area, the second control module wakes up the second communication module, which sends a fourth alarm request to the cloud management platform 11. The cloud management platform 11 generates an abnormal personnel intrusion warning message for the in-transit monitoring device based on the fourth alarm request.

[0047] In summary, by collecting relevant parameters through the environmental perception module, positioning module, image acquisition module, and human detection sensor, and analyzing these parameters through the second control module, this invention can promptly detect environmental anomalies, transportation route anomalies, and unauthorized personnel intrusions, and issue remote alarms, thus improving the on-the-go safety of this invention. Furthermore, by keeping the second communication module, positioning module, and image acquisition module in a low-power state during normal operation, only waking them up in case of anomalies, this invention saves energy, with a standby power consumption of 0.1W.

[0048] In this embodiment of the invention, the multi-state sensing sample in-transit monitoring device may further include a second storage device. The second storage device may be a TF card.

[0049] The second control module is also used to encrypt and store the relevant data of the environmental anomaly to the second storage device when it is determined that there is an environmental anomaly.

[0050] The second control module is also used to encrypt and store the location data and related data to the second storage device when it is determined that the location data does not meet the preset location data requirements.

[0051] The second control module is also used to encrypt and store the relevant data of abnormal personnel in the second storage device when it is determined that there are abnormal personnel in the monitoring area.

[0052] In this embodiment of the invention, the material quality sampling and sealing management system may further include a sampling device.

[0053] The sampling device scans the sampling area using radio frequency signals emitted by its radio frequency antenna array, receives response signals from the target sample, and analyzes the response signals using a signal attenuation model based on RSSI (Received Signal Strength Indicator) to obtain the location result of the target sample. Based on the location result, the transmission power of the radio frequency antenna array is dynamically adjusted to achieve gradient scanning from the far field to the near field until the position of the target sample is determined. This allows the invention to improve sampling efficiency and reduce manual workload.

[0054] In this embodiment of the invention, the expression for the signal attenuation model can be as follows:

[0055] in, To be at a distance of from the radio frequency antenna array Measured RSSI at the location To ensure the distance to the RF antenna array is a preset reference distance. The RSSI calibration at the location.

[0056] In addition, the sampling device may also include a card slot adapted to the mobile terminal 12, in which the mobile terminal 12 can be fixed, thus allowing the user to hold both the sampling device and the mobile terminal 12 at the same time.
