[0031] Example 1

[0032] Figure 1 This is a structural diagram of a power material sampling inspection system provided in the first embodiment of the present invention. The system can be applied to ensure the safety of the samples being inspected during the process of spot-checking power materials.

[0033] like Figure 1 As shown, a power material sampling inspection system provided by the first embodiment of the present invention includes:

[0034] The monitoring platform 100 is used to create a random inspection task for power materials and send the random inspection task to the corresponding random inspection terminal 200, wherein the random inspection task includes a specified sample to be inspected;

[0035] The sampling inspection terminal 200 is used to obtain the encrypted device identification of the anti-tampering monitoring device based on the sampling inspection stage and sampling inspection task of the sample being inspected, and send the device identification to the monitoring platform 100; the anti-tampering monitoring device is set on the sample being inspected;

[0036] The monitoring platform 100 is also used to verify the security of the anti-dismantling monitoring device based on the device identification and the sampling inspection task, obtain a verification result, and send the verification result to the sampling inspection terminal 200 so that the sampling inspection terminal 200 processes the sample to be inspected based on the verification result.

[0037] Among them, the monitoring platform 100 can be a platform system that can manage the random inspection of electric power materials. For example, the monitoring platform 100 can include functions such as random inspection task management, random inspection task status monitoring, real-time monitoring data display of anti-dismantling monitoring devices, real-time alarm display of anti-dismantling monitoring devices, real-time position and trajectory display of anti-dismantling monitoring devices, and random inspection process recording. The random inspection task can be a task generated based on the electric power materials that need to be inspected. The random inspection task can include designated samples to be inspected, and can also include the number of the inspected samples. The inspected samples can be selected electric power materials. The random inspection terminal 200 can be a terminal that includes random inspection application software (Application, APP). The anti-dismantling monitoring device can be a device that can be attached to the inspected sample and can monitor whether the inspected sample has safety hazards. The device identifier can be a unique identifier of the anti-dismantling monitoring device.

[0038] In this embodiment, when it is necessary to conduct random inspections on power materials, the monitoring platform 100 can create a random inspection task and send the random inspection task to the corresponding random inspection terminal 200; after receiving the random inspection task, the random inspection terminal 200 needs to complete the corresponding operation, specifically, based on the random inspection stage and random inspection task of the sample being inspected, the encrypted device identification of the corresponding anti-dismantling monitoring device can be obtained. For example, if the random inspection task includes the number of the corresponding sample being inspected, the corresponding sample can be found according to the number, and the encrypted device identification of the anti-dismantling monitoring device on the corresponding sample can be obtained. The random inspection terminal 200 can send the device identification to the monitoring platform 100, and the monitoring platform 100 can verify whether the device identification is correct based on the information contained in the random inspection task, obtain the verification result, and send the verification result to the random inspection terminal 200.

[0039] In the existing methods, whether paper labels or electronic labels are used, physical labels need to be affixed to samples during random inspections, and the random inspection task information, blind sample information, and label information need to be associated and bound to form a complete data chain. The use of explicit device numbers or QR codes can easily leak sample information from the sample sealing link to the inspection link. Electronic tags using RFID or (Near Field Communication, NFC) technology have unique identifications (Identity, ID) and can be identified by mobile phones or card readers. There is also a risk of illegally obtaining the label ID and tracing the sample, thereby leaking sample information. The device identification of the anti-dismantling monitoring device obtained in this embodiment is an encrypted device identification. The real information of the anti-dismantling monitoring device and the sample information will not be obtained by the user, thereby preventing the leakage of information of the anti-dismantling monitoring device and the sample being inspected.

[0040] A first embodiment of the present invention provides a system for spot-checking electric power materials, a monitoring platform for creating spot-checking tasks for electric power materials, and sending the spot-checking tasks to corresponding spot-checking terminals, wherein the spot-checking tasks include designated samples to be spot-checked; the spot-checking terminals are used to obtain an encrypted device identification of an anti-disassembly monitoring device based on the spot-checking stage and spot-checking tasks of the sample to be spot-checked, and send the device identification to the monitoring platform; the anti-disassembly monitoring device is provided on the sample to be spot-checked; the monitoring platform is also used to verify the security of the anti-disassembly monitoring device based on the device identification and the spot-checking tasks, obtain a verification result, and send the verification result to the spot-checking terminal so that the spot-checking terminal processes the sample to be spot-checked based on the verification result. The system assigns tasks through the monitoring platform, verifies the encrypted device identification obtained by the spot-checking terminal, and processes the sample to be spot-checked according to the verification result, thereby ensuring the safety of the sample when it is spot-checked, and solving the problem of security risks of the sample to be spot-checked in the prior art.

[0041] Based on the above embodiment, a modified embodiment of the above embodiment is proposed. It should be noted that, in order to simplify the description, only the differences from the above embodiment are described in the modified embodiment.

[0042] In one embodiment, the sampling inspection terminal 200 is specifically configured to send the virtual identifier of the anti-tampering monitoring device to the monitoring platform 100 after reading the virtual identifier;

[0043] The monitoring platform 100 is configured to send the encrypted public key to the sampling inspection terminal 200 when the virtual identifier is the same as the preset identifier, so that the sampling inspection terminal 200 reads the encrypted device identification in the anti-tampering monitoring device based on the encrypted public key.

[0044] The virtual identifier may be an identifier written into the anti-tampering monitoring device when it leaves the factory. The virtual identifiers of all anti-tampering monitoring devices may be the same.

[0045] In this embodiment, the encrypted device identifier stored in the tamper-evident monitoring device requires an encrypted public key to read. Therefore, after reading the virtual identifier on the tamper-evident monitoring device, the sampling inspection terminal 200 sends the virtual identifier to the monitoring platform 100. The monitoring platform 100 compares the virtual identifier with a preset identifier. If the virtual identifier matches the preset identifier, the corresponding encrypted public key can be sent to the sampling inspection terminal 200, which can then read the encrypted device identifier based on the encrypted public key. If the virtual identifier differs from the preset identifier, it indicates that the virtual identifier of the tamper-evident monitoring device may have been tampered with, or the tamper-evident monitoring device may have been replaced, in which case an alarm message can be issued.

[0046] In this embodiment, the sampling inspection terminal 200 needs to encrypt the public key to obtain the device identification of the anti-dismantling monitoring device, and the obtained device identification of the anti-dismantling monitoring device is also encrypted. By anonymizing the device identification in the monitoring device and building a dual authentication identification tag mechanism, the problem of sample information leakage during the sampling inspection process can be solved.

[0047] In one embodiment, the monitoring platform 100 is specifically configured to decrypt the device identification based on the encryption private key to obtain the decrypted device identification, and perform security verification on the decrypted device identification based on the sampling inspection task to obtain a verification result.

[0048] In this embodiment, after the monitoring platform 100 obtains the encrypted device identification, it will decrypt the device identification using the encryption private key to obtain the decrypted device identification. Based on the information stored in the sampling task (such as the device identification), it can determine whether the decrypted device identification corresponds to the sampling task and generate a verification result. The verification result may include verification success, verification failure, or verification error.

[0049] For example, a MIFARE Classic IC tag can be used inside the anti-tampering monitoring device. Sector 0 of the tag is readable and writable, and the same virtual identifier is rewritten to all tags when the device leaves the factory to achieve normalization of the tag surface ID. The device can use the microcontroller unit (MCU) hardware encoding as the real ID of the device, and write it to the sector 0 data block after encryption using an asymmetric encryption algorithm (Rivest-Shamir-Adleman, RSA). At the same time, the tag storage control block uses an encryption public key (such as KeyA and KeyB) to encrypt and authenticate the reading and writing of the sector 0 data area. KeyA, KeyB and RSA private keys are all stored on the monitoring platform, and the sampling terminal APP and the monitoring platform can communicate through the intranet security platform. After the APP reads the specified virtual identifier in the device, it can request KeyA and KeyB from the monitoring platform to read the encrypted data of sector 0, and then hand it over to the monitoring platform for RSA decryption. App users are required to bind the sampling task to the real ID on the device tag during the sample sealing process, match the sampling task with the real ID on the device tag during the sampling process, and verify the sampling task and the real ID on the device tag during the sample receiving process. During this process, all data is securely exchanged only between the tag, the app, and the monitoring platform. By anonymizing the device tag's virtual ID and dual-authenticating the real ID, combined with a uniform, undifferentiated device design, the risk of private information leaks caused by suspects attempting to trace the sample's origin by identifying the tag's unique ID can be effectively avoided.

[0050] In one embodiment, the sampling inspection terminal 200 is further configured to: when the verification result is a verification failure, stop the sampling inspection task for the sample being inspected, and notify a staff member to inspect the sample being inspected.

[0051] In this embodiment, if the verification result is verification failure, the sample being inspected may have a safety risk. At this time, the inspection terminal 200 can stop the inspection task of the sample being inspected, notify the corresponding staff to inspect the sample being inspected, and check for possible risks.

[0052] In one embodiment, the sampling terminal 200 includes: a sampling terminal, wherein the sampling stage includes a waiting sampling stage;

[0053] The sampling terminal is used to obtain the encrypted device identification of the anti-dismantling monitoring device when receiving the sampling task and the sampling stage of the sample being sampled is the waiting stage, bind the sampling task and the device identification, obtain an updated sampling task, and send the updated sampling task to the monitoring platform 100 so that the monitoring platform 100 updates the sampling task.

[0054] The sampling terminal may include a sampling terminal, which can be used to collect samples. The sampling stage may refer to the stage where the samples are packaged and removed by staff. Different sampling terminals can provide operational process guidance, process records, and data communication for different staff members (such as sample collectors, sample delivery personnel, and sample receivers).

[0055] In this embodiment, when the sampling terminal receives the sampling task, if the sampling stage of the sample being sampled is the waiting sampling stage, the encrypted device identification of the anti-dismantling monitoring device can be obtained, and the device identification can be bound to the sampling task to obtain an updated sampling task. The updated sampling task can include the device identification, and then the updated sampling task can be sent to the monitoring platform 100 so that the monitoring platform 100 can update the sampling task.

[0056] In one embodiment, the sampling inspection terminal 200 includes: a sample delivery terminal and a sample receiving terminal, and the sampling inspection stage includes a sample delivery stage and a sample receiving stage;

[0057] The sample delivery terminal is used to obtain the encrypted device identification of the anti-tampering monitoring device when receiving the sampling inspection task sent by the monitoring platform and the sampling stage of the sample to be inspected is the sample delivery stage, and send the device identification to the monitoring platform 100;

[0058] The sample receiving terminal is used to obtain the encrypted device identification of the anti-dismantling monitoring device and send the device identification to the monitoring platform 100 when receiving the sampling inspection task sent by the monitoring platform and the sampling stage of the sample being inspected is the sampling stage.

[0059] The sample delivery terminal may be a terminal used when delivering samples to be inspected, and the sample receiving terminal may be a terminal used when receiving the samples to be inspected.

[0060] In this embodiment, when the sample delivery terminal and the sample receiving terminal receive the sampling task, they can execute the corresponding sampling task according to the sampling stage of the sample being sampled. However, when executing the task, they both need to obtain the encrypted device identification of the anti-dismantling monitoring device and send the device identification to the monitoring platform 100 so that the monitoring platform 100 can verify the device identification.

[0061] In one embodiment, the system further includes an anti-tampering monitoring device, which is connected to the monitoring platform 100 and the sampling inspection terminal 200 respectively;

[0062] The anti-dismantling monitoring device is used to obtain the sampling inspection task sent by the monitoring platform 100, monitor the sampled samples in real time based on the sampling inspection task, and send an alarm message to the monitoring platform 100 and the sampling inspection terminal 200 when it is detected that the sampled samples have safety hazards.

[0063] In this embodiment, the tamper-evident monitoring device can be connected to the monitoring platform 100 and the sampling inspection terminal 200, respectively. After receiving the sampling inspection task sent by the monitoring platform 100, the tamper-evident monitoring device can monitor the status of the sample being inspected in real time based on the sampling inspection task when the sampling inspection task is valid. When the sample being inspected is detected to have a safety hazard, an alarm information is sent to the monitoring platform 100 and the sampling inspection terminal 200. The tamper-evident monitoring device can also send the real-time monitored information of the sample being inspected (such as the pressed switch status, resistance value, vibration amplitude, and positioning information) to the monitoring platform.

[0064] In one embodiment, the anti-tampering monitoring device includes a microcontroller unit configured to:

[0065] When one or more of the following conditions are detected in the anti-dismantling monitoring device, an alarm message is sent: the push switch of the anti-dismantling monitoring device is in the pop-up state, the resistance of the photoresistor is less than the resistance threshold, the vibration amplitude detected by the acceleration sensor is greater than the vibration threshold, or the transportation trajectory obtained by the positioning module deviates from the preset transportation trajectory.

[0066] In this embodiment, the anti-dismantling monitoring device may include a microcontroller unit, which can process information sent by a push switch, a photoresistor, an acceleration sensor, and a positioning module, and send an alarm message when it is detected that the push switch of the anti-dismantling monitoring device is in a pop-up state, the resistance of the photoresistor is less than the resistance threshold, the vibration amplitude detected by the acceleration sensor is greater than the vibration threshold, or the transportation trajectory obtained by the positioning module deviates from the preset transportation trajectory.

[0067] For example, after the anti-dismantling monitoring device is bound to the sample being inspected, the push switch XKB5858 should be in the pressed state and the resistance of the photoresistor GL5506 should be greater than the set resistance threshold. When the push switch pops up or the resistance of the photoresistor is less than the resistance threshold, it can be determined that the anti-dismantling monitoring device is being removed from the sample being inspected, and there is a risk of illegal sample replacement. Then, an interrupt can be triggered to wake up the processor STM32L151 or the microcontroller to generate a corresponding alarm message and send it to the monitoring platform via 4G. At the same time, the vibration amplitude of any axis of the anti-dismantling monitoring device can be detected by the three-axis acceleration sensor ADXL345. If the vibration amplitude of any axis exceeds the set vibration threshold, it is determined that the anti-dismantling monitoring device and the sample being inspected are at risk of being illegally moved or driven illegally (for example, when driving illegally, the shaking amplitude of the sample being inspected is large). The processor generates a corresponding alarm message and sends it to the monitoring platform via 4G.

[0068] This embodiment monitors the sample binding status and vibration changes by detecting multiple technical principles such as key switch status, light intensity and three-axis impact. When a suspected person illegally destroys the sample seal and one of the technical means fails, the device can still alarm in time, solving the problem of random sample replacement.

[0069] In this embodiment, the global satellite positioning module can also be used to obtain real-time location information of samples bound for inspection during delivery and upload it to the monitoring platform. By setting a preset transportation route for the inspection task, inspection management and supervision personnel can control the trajectory deviation alarms and overtime alarms of the inspected samples during transportation, promptly preventing or blocking suspected illegal attempts to destroy the inspected samples. The anti-tampering monitoring device can track the location of the inspected samples on the monitoring platform through satellite positioning and intranet mobile communications, solving the problem of route trajectory control after sample sealing and during the delivery process.

[0070] The monitoring platform of this embodiment can automatically transfer information to the APP of the staff who take, seal, deliver and receive samples according to the sampling process. The staff follows the steps prompted by the APP and records them on the monitoring platform, which can solve the problem of information overlap in various links in the sampling inspection and the inability to trace the process.

[0071] The embodiments of the present invention provide several specific implementation methods based on the technical solutions of the above embodiments.

[0072] As a specific implementation method of this embodiment, Figure 2 A schematic diagram of a power material sampling process provided by an embodiment of the present invention is shown in FIG. Figure 2 As shown in the figure, the random inspection process of power materials includes sampling, sealing, sending and receiving of samples. The details are as follows:

[0073] 1. The sampling inspection manager creates a sampling inspection task on the monitoring platform and selects the sampling inspection warehouse, samples and testing units;

[0074] 2. The monitoring platform assigns the sampling task to the terminal of the sample taker. The sample taker carries the anti-tampering monitoring device to the designated warehouse and takes out the sample according to the sample number;

[0075] 3. The sample sealer seals the sample, uses the terminal APP to read the label information of the anti-tampering monitoring device, binds the sampling task, the sample to be sampled and the anti-tampering monitoring device, sticks the anti-tampering monitoring device on the sample to be sampled, and the anti-tampering monitoring device starts real-time positioning and anti-tampering alarm.

[0076] 4. The monitoring platform assigns sampling tasks to sample delivery personnel. Sample delivery personnel read the label information of the anti-tampering monitoring device in the sealed sample area of ​​the designated warehouse through the terminal APP, match the sampling tasks and samples, and deliver them to the designated testing unit.

[0077] 5. The monitoring platform assigns the sampling task to the sample receiver, and the anti-tampering monitoring device starts real-time positioning and anti-tampering alarms. The sample receiver's terminal app reads the anti-tampering monitoring device's tag information, verifies the sampling task, sample, and anti-tampering monitoring device information are consistent, and then accepts or returns it.

[0078] 6. When the anti-tampering monitoring device is not in a task state, it can regularly send heartbeat information to the monitoring platform.

[0079] The administrator can monitor the information sent by the anti-tampering monitoring device on the monitoring platform, control the sampling process, and when the anti-tampering monitoring device is returned to the user unit, it can be recharged and wait for reuse.

[0080] In this embodiment, a secure communication link is established between the monitoring platform and the sampling terminal and the anti-dismantling monitoring device. The monitoring platform automatically transfers task information to the sampling terminals of the sample collector, sample delivery personnel and sample receiver. Through multi-level access control and the principle of least privilege, zero-trust information isolation is established between personnel in different links to avoid cross-link data association risks. At the same time, different sampling terminals can isolate privacy information between roles to avoid information leakage. All operations leave traces in the system, and the entire sampling task can be traced. The APP in the sampling terminal guides personnel operations according to the standard sampling process. The monitoring platform can record personnel behavior word by word and leave traces step by step, realizing the event tracing and data management analysis of the sampling task process by sampling management and supervision personnel.

[0081] Figure 3 A schematic diagram of the structure of a power material sampling inspection system provided by an embodiment of the present invention is shown as follows: Figure 3 As shown, the monitoring platform may include a Web front-end, a business back-end, a database and a communication module; the sampling inspection terminal (such as a mobile phone APP) may include an NFC module, a mobile communication module and a business module; the anti-disassembly detection device may include an M1 tag, a hard encryption module, a mobile communication module, a storage module, a microcontroller unit, a power management unit, a positioning module, a push switch, a photoresistor and an acceleration sensor.

[0082] Example 2

[0083] Figure 4 This is a schematic diagram of the structure of a disassembly monitoring device provided in the second embodiment of the present invention, which can be used to ensure the safety of the sample being inspected during the random inspection of power materials. The disassembly monitoring device can be installed on the sample being inspected.

[0084] like Figure 4 As shown, the tamper-evident monitoring device includes a communication tag 300 , and the communication tag 300 is used to store a virtual identifier and an encrypted device identification.

[0085] The communication tag 300 may be an M1 tag.

[0086] In this embodiment, the tamper-evident monitoring device may include a communication tag 300, which may store a virtual identifier and an encrypted device identification. For example, the device identification may be RSA-encrypted and written to the sector 0 data block of the communication tag. Simultaneously, encryption public keys (e.g., KeyA and KeyB) are used to encrypt and authenticate reads and writes to the sector 0 data block of the tag storage control block.

[0087] This embodiment provides a tamper-evident monitoring device, which is installed on a sample being inspected. The device includes a communication tag that stores a virtual identifier and an encrypted device identifier. The tamper-evident monitoring device can monitor the status of the sample being inspected. By setting the virtual identifier and encrypted device identifier, information leakage of the device and the sample can be prevented.

[0088] In one embodiment, the anti-tampering monitoring device further comprises: a microcontroller unit, a push switch, a photoresistor, an acceleration sensor, and a positioning module, wherein the microcontroller unit is connected to the push switch, the photoresistor, the acceleration sensor, and the positioning module respectively;

[0089] The push switch is used to send the switch status to the micro control unit;

[0090] The photoresistor is used to send the resistance value to the micro control unit;

[0091] The acceleration sensor is used to send the detected vibration amplitude to the micro control unit;

[0092] The positioning module is used to send the detected transport track to the micro control unit;

[0093] The micro control unit determines whether to send an alarm message to the monitoring platform in the electric power material sampling inspection system as described in any embodiment of the present invention based on the received switch state, the resistance value, the vibration amplitude and the transportation trajectory.

[0094] In this embodiment, the anti-dismantling monitoring device may include a microcontroller unit, which can process information sent by a push switch, a photoresistor, an acceleration sensor, and a positioning module, and send an alarm message when it is detected that the push switch of the anti-dismantling monitoring device is in a pop-up state, the resistance of the photoresistor is less than the resistance threshold, the vibration amplitude detected by the acceleration sensor is greater than the vibration threshold, or the transportation trajectory obtained by the positioning module deviates from the preset transportation trajectory.
