Description

Technical Field

[0001] The present invention belongs to the technical field of quality of metallurgical raw materials, fuels and auxiliary materials, and specifically relates to a method for multiple encryption of the whole process of quality inspection of incoming raw materials. Background Art

[0002] The ferrous metal smelting industry requires the procurement of a wide variety of industrial raw materials, such as coal, coke, iron-containing materials, solvents, and alloys. Most metal smelting companies purchase large quantities of raw materials, fuels, and auxiliary materials from numerous suppliers, and the quality of these raw materials has a profound impact on production, cost, and quality control. Currently, the common method for domestic raw material encryption is the construction of automatic samplers. However, these machines are subject to high construction and maintenance costs, as well as limitations in adaptability to all materials and regions. Therefore, manual sampling remains widely used in the metallurgical industry. However, manual sampling carries the risk of sensitive information leakage, potentially harming corporate interests. Summary of the Invention

[0003] The purpose of the present invention is to provide a method for multiple encryption of the whole process control of raw material incoming quality inspection, aiming to solve the problem that there is a risk of sensitive information leakage in the manual sampling process in the existing technology, which may cause damage to corporate interests.

[0004] To achieve the above object, the present invention provides the following technical solutions: A method for controlling the entire quality inspection process of incoming raw materials with multiple encryption, comprising the following steps: S1. Establish an encryption information management system to store and manage encryption information in all links; S2. The sampling personnel use a handheld device equipped with an encryption program to input the basic information of the raw materials. The encryption program encrypts the basic information of the raw materials to generate encrypted raw material information. The handheld device prints a label containing the encrypted information. The sampling personnel affixes the label to the sample container and uploads the encrypted information to the encryption information management system. S3. The sample preparation device reads the encryption label on the sample container, interacts with the encryption information management system to obtain the encryption information of the sampling process, encrypts the sample preparation process information using the sample preparation-related dynamic encryption factor combined with the encryption information of the sampling process, and stores the encrypted sample preparation information in the sample preparation process database; S4. The testing equipment tests the sample to obtain the test results. The encrypted information management system calls the encrypted information of the sampling and sample preparation process, uses blockchain encryption technology to generate a blockchain data block containing all the information, generates a unique blockchain hash value for the test result, and stores it in the blockchain node. At the same time, the system judges the test result according to the preset standards, and triggers the early warning mechanism if there is any abnormality; S5. Preset batching rules in the encrypted information management system and set barreling rules based on raw material-related information. When samples are delivered to the barreling area, the system automatically identifies the sample information and barrels them according to the batching rules. The system monitors the status of the sample barrels and automatically sends a barrel-clearing reminder to the operator when the barrel is full.

[0005] As a preferred solution of the present invention, the basic information of raw materials in S2 includes supplier name, raw material batch number, and raw material origin information, wherein the encryption program encrypts the basic information of raw materials and includes the following steps: Step 1: Preset the supplier name according to the letters A to Z, and use the alphanumeric conversion rules to convert each letter into the corresponding two-digit number; Step 2: Insert three random digits at the beginning and end of the raw material batch number and shuffle them. Take the pinyin initials of the raw material origin information and convert them into hexadecimal code to generate encrypted raw material information. Step 3: The handheld device prints a label containing the encrypted information. The sampling personnel stick the label on the sample container and upload the encrypted information to the encrypted information management system in real time via the wireless network.

[0006] As a preferred solution of the present invention, in S3, the sample preparation start time, the sample preparation equipment number, and the current operating parameters of the sample preparation equipment are used as dynamic encryption factors, and the sample preparation personnel number, sample preparation steps, and sample preparation process information are encrypted based on a hash function combined with the sampling link encryption information. The encrypted sample preparation information is stored in a sample preparation process database, and the database is synchronized and updated in real time with the encryption information management system.

[0007] As a preferred solution of the present invention, the testing equipment in S4 detects the sample to obtain the test results, and the test results include chemical composition content and physical performance indicators. The encrypted information management system calls the encrypted information of the sampling and sample preparation links, uses blockchain encryption technology to generate a blockchain data block containing all the information, generates a unique blockchain hash value for the test result, and stores it in association with the blockchain node.

[0008] As a preferred solution of the present invention, the encrypted information management system presets standards for different types of raw materials, and then determines the test results based on the preset standards. If there is any abnormality, an early warning mechanism is triggered.

[0009] As a preferred solution of the present invention, the notification method of the early warning mechanism includes text messages and system pop-up windows. The text message content contains abnormal result details, sample number and timestamp, and the system pop-up window content displays abnormal result data and impact analysis.

[0010] As a preferred solution of the present invention, a batching rule is preset in the encryption information management system, specifically comprising the following steps: Step 1: Set barreling rules based on raw material type, supplier, and batch information. When samples are delivered to the barreling area, the system automatically identifies the sample information and barrels according to the batching rules. The barrels are labeled and a full barrel threshold is preset. Step 2: The system monitors the status of the sample barrel. When the number of samples in the barrel reaches the preset full barrel threshold, it automatically sends a reminder to the operator to clear the barrel.

[0011] As a preferred solution of the present invention, the barrel clearing reminder method includes displaying a striking reminder message on the operation terminal, issuing a voice alarm, and sending a reminder text message to the operator's mobile phone.

[0012] As a preferred solution of the present invention, in the encryption rules of the basic information of raw materials, the digital code converted from the supplier name, the scrambled reorganization method of the raw material batch number and the coding conversion method of the raw material origin information ensure the uniqueness and confidentiality of the information.

[0013] As a preferred solution of the present invention, the acquisition and conversion method of the sample preparation-related dynamic encryption factor ensures the dynamism and security of encryption, and the encryption algorithm based on the hash function produces a unique encryption result each time encryption is performed.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention establishes an encrypted information management system as the storage and management core of encrypted information in the entire quality inspection process, providing a basic platform for the interaction and storage of encrypted information in each link, ensuring the orderly flow and secure storage of information, and realizing centralized management of information throughout the entire process of raw material entry quality inspection. Its data storage function ensures that encrypted information in each link is completely preserved, the information interaction function promotes the accurate transmission of encrypted information between different processes, and the encryption processing function ensures the security of information from the source. This lays a solid foundation for subsequent encryption operations, effectively prevents the risk of information leakage caused by chaotic information management, improves the standardization and security of information management in the entire quality inspection process, and helps enterprises to effectively trace and control raw material quality inspection data.

[0015] 2. In the present invention, sampling personnel use handheld devices equipped with encryption programs to perform complex encryption operations on supplier names, raw material batch numbers, and raw material origin information. The supplier name is converted into a specific digital code, the raw material batch number is shuffled and reorganized, and the raw material origin information is encoded and converted, greatly increasing the difficulty of information decryption. The handheld device prints the encrypted label and uploads the information in real time, achieving encryption protection from the source of information acquisition. This not only effectively prevents information leakage during the sampling process, making it difficult for others to obtain sensitive information such as the true raw material source even if the sample container is accidentally exposed, but also provides accurate and confidential basic data for subsequent sample preparation and testing, ensuring the integrity and confidentiality of the information chain throughout the quality inspection process. This helps companies control raw material quality risks at the source of procurement and avoid supplier credibility issues or raw material quality disputes caused by information leakage.

[0016] 3. In the present invention, after the sample preparation equipment reads the encrypted tag to obtain sampling information, it uses the sample preparation start time, equipment number, and operating parameters as dynamic encryption factors. A hash function is then combined with the sample encryption information to encrypt the sample preparation personnel number and steps. This approach further enhances information confidentiality, closely linking sample preparation process information with the sampling process and storing them in encrypted form. Even if there is a risk of information leakage during the sample preparation process, the dynamic and complex nature of the encryption factors makes it difficult to decipher the entire process information.

[0017] 4. In the present invention, after the test equipment is tested, the encrypted information management system calls the encrypted information in the previous link, and generates a blockchain data block and hash value containing all the information through blockchain technology. The tamper-proof feature of the blockchain ensures the authenticity and integrity of the test results and the entire quality inspection process data, effectively preventing information leakage or result tampering, and providing a highly reliable basis for enterprise quality control and decision-making. The system automatically determines the test results according to preset standards, and notifies relevant personnel in time through text messages and pop-up windows in case of abnormalities, thereby improving the timeliness of abnormal result processing.

[0018] 5. This invention uses pre-set batching rules within the encrypted information management system to automatically bucket materials based on information such as raw material type, supplier, and batch number, reducing the risk of errors and information leakage during manual intervention. The system monitors the status of buckets and alerts operators through various means when a bucket is full, ensuring that operators can clear the buckets promptly for sample preparation. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The accompanying drawings are used to provide a further understanding of the present invention and constitute a part of the specification. Together with the embodiments of the present invention, they are used to explain the present invention and do not constitute a limitation of the present invention. In the accompanying drawings: Figure 1 This is a flowchart of a method for full-process control and multiple encryption of incoming raw material quality inspection in the present invention. DETAILED DESCRIPTION

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example 1 See also Figure 1 The present invention provides the following technical solution: a method for controlling the whole process of quality inspection of incoming raw materials with multiple encryption, comprising the following steps: S1. Establish an encryption information management system to store and manage encryption information in all links; S2. The sampling personnel use a handheld device equipped with an encryption program to input the basic information of the raw materials. The encryption program encrypts the basic information of the raw materials to generate encrypted raw material information. The handheld device prints a label containing the encrypted information. The sampling personnel affixes the label to the sample container and uploads the encrypted information to the encryption information management system. S3. The sample preparation device reads the encryption label on the sample container, interacts with the encryption information management system to obtain the encryption information of the sampling process, encrypts the sample preparation process information using the sample preparation-related dynamic encryption factor combined with the encryption information of the sampling process, and stores the encrypted sample preparation information in the sample preparation process database; S4. The testing equipment tests the sample to obtain the test results. The encrypted information management system calls the encrypted information of the sampling and sample preparation process, uses blockchain encryption technology to generate a blockchain data block containing all the information, generates a unique blockchain hash value for the test result, and stores it in the blockchain node. At the same time, the system judges the test result according to the preset standards, and triggers the early warning mechanism if there is any abnormality; S5. Preset batching rules in the encrypted information management system and set barreling rules based on raw material information. When samples are delivered to the barreling area, the system automatically identifies the sample information and barrels according to the batching rules. The system monitors the status of sample barrels and automatically issues a reminder to the operator to clear the barrel when it is full.

[0022] In a specific embodiment of the present invention, the first encryption (sampling stage) uses a unique coding system to encrypt basic information such as raw material batches and suppliers. For example, the supplier name is converted into a specific digital code, and the raw material batch number is scrambled and reorganized. The operation process includes the following: when collecting raw material samples, the sampling personnel use a handheld device to input the basic information of the raw materials. The device has a built-in encryption program that automatically encrypts the input information and generates an encrypted label. The label is then affixed to the sample container, and the encrypted information is uploaded to the encryption information management system. This has the advantage of encrypting the raw material information at the source, preventing information leakage during the sampling stage. Even if the sample container is accidentally exposed, it is difficult for others to obtain sensitive information such as the true source of the raw materials. The second encryption (sample preparation stage) is based on the encryption information of the sampling stage, introduces a dynamic encryption algorithm, uses variables such as sample preparation time and sample preparation equipment number as encryption factors, and encrypts the intermediate information of the sample in the sample preparation process (such as sample preparation steps, sample preparation personnel number, etc.); in the operation process, when the sample enters the sample preparation stage, the sample preparation equipment reads the encryption label on the sample container, and obtains the encryption information of the sampling stage by interacting with the encryption information management system. Then, according to the dynamic encryption algorithm, combined with the relevant variables of the current sample preparation, the sample preparation process information is encrypted and recorded in the sample preparation process database, which is connected to the encryption information management system; its advantage is that it further increases the confidentiality of information, so that the information of the sample preparation stage is closely related to the sampling stage and encrypted and stored. Even if there is a risk of information leakage in the sample preparation stage, it is difficult to crack the entire process information; the third encryption (chemical In the testing link), the encryption method uses blockchain encryption technology to integrate and encrypt the test results with the previous sampling and sample preparation encryption information, generate a unique blockchain hash value for each test result, and store it in association with the relevant encrypted information in the blockchain node; in the operation process, after the test equipment tests the sample, the test result is transmitted to the encrypted information management system. The system uses blockchain encryption technology and combines the encrypted information of the previous link to generate an encrypted data block containing the test result and add it to the blockchain. At the same time, the system automatically makes a preliminary judgment on the test result according to preset rules (such as the quality standard range). If the result is abnormal, the early warning mechanism is triggered; its advantage is that the tamper-proof nature of the blockchain ensures the authenticity and integrity of the test results. At the same time, multiple encryptions ensure the high security of the information of the entire quality inspection process, effectively preventing corporate interests from being damaged by information leakage or result tampering; Automatic bucketing and reminders: Bucketing rules: Based on preset batching rules such as raw material type and batch, the system automatically allocates samples to corresponding sample buckets. For example, raw material samples from the same supplier and the same batch are allocated to the same bucket. Reminder operation: When the sample barrel is full according to the batching rules, the system automatically sends a reminder to the operator to clear the barrel, such as by flashing the display, sending SMS or pushing system messages. After receiving the reminder, the operator takes the sample out of the barrel and performs sample preparation operations; Advantages: Reduce manual intervention in the bucketing process, reduce the risk of human error and information leakage, and improve the accuracy and efficiency of the process; Through triple encryption and unique encryption technology application, sensitive information in the sampling, sample preparation and testing links is completely isolated, effectively preventing information leakage and protecting corporate trade secrets. The application of blockchain encryption technology ensures that the test results and the entire quality inspection process data cannot be tampered with, ensuring the integrity and authenticity of the data, providing a reliable basis for corporate quality control and decision-making, reducing manual participation in sensitive links, and reducing information leakage and quality risks caused by human factors. It helps companies stabilize production and control costs, thereby protecting corporate interests from loss. The automatic bucketing and reminder functions improve the degree of automation in sample processing, reduce manual operation errors, and improve the efficiency of the entire quality inspection process.

[0023] Specifically, a method for controlling the entire process of incoming raw material quality inspection with multiple encryption includes the following steps: S1. Establish an encrypted information management system with data storage, information exchange and encryption processing functions for storing and managing encrypted information at all stages; S2. The sampling personnel use a handheld device equipped with an encryption program to input basic raw material information, including supplier name, raw material batch number, and raw material origin information. The encryption program converts each letter of the supplier name into a corresponding two-digit number according to a preset letter-to-digit conversion rule (where A corresponds to 01, B corresponds to 02, and so on). The raw material batch number is inserted with three random digits at the beginning and end, and then scrambled and reorganized. The raw material origin information is converted into a hexadecimal code by combining the first letters of its pinyin. This generates encrypted raw material information. The handheld device prints a label containing the encrypted information. The sampling personnel affix the label to the sample container and upload the encrypted information to the encryption information management system in real time via the wireless network. S3. The sample preparation device reads the encrypted label on the sample container and interacts with the encryption information management system to obtain the encrypted information of the sampling process. The sample preparation start time (accurate to milliseconds, the time is counted from the start of the sample preparation device and is based on the system time), the sample preparation device number (a unique identification code set when the device leaves the factory, a ten-digit number and a combination of letters), and the current operating parameters of the sample preparation device (including the device temperature, accurate to 0.1 degrees Celsius and converted to a three-digit code; the device pressure, accurate to 0.01 MPa and converted to a four-digit code; the device speed, accurate to 1 revolution per minute and converted to a five-digit code) are used as dynamic encryption factors. A hash function (such as the SHA-256 algorithm) is used in combination with the encrypted information of the sampling process to encrypt the sample preparation personnel number (an eight-digit employee number) and the sample preparation steps (including the crushing time of the crushing operation, accurate to seconds; the sieving mesh size of the sieving operation, an integer; and the grinding time of the grinding operation, accurate to minutes). The encrypted sample preparation information is then stored in the sample preparation process database, which is synchronized and updated in real time with the encryption information management system. S4. The testing equipment detects the samples and obtains the test results. The test results include chemical composition content (such as the calorific value of coal is accurate to 0.1 kcal / kg, the ash content is accurate to 0.01%, and the sulfur content is accurate to 0.001%; the iron content of iron-containing materials is accurate to 0.01%, the impurity element content is accurate to 0.001%; the alloy element content of alloys is accurate to 0.01%), physical performance indicators (such as the density of raw materials is accurate to 0.001 g / cubic centimeter, and the hardness is accurate to 0.1 Rockwell hardness). The encrypted information management system calls the encrypted information of the sampling and sample preparation links, uses blockchain encryption technology to generate a blockchain data block containing all the information, generates a unique blockchain hash value for the test results and stores it in the blockchain node. At the same time, the system calculates the hash value based on the preset standards ( For example, the standard range for the calorific value of coal is [X1, X2] kcal / kg, the standard range for ash content is [Y1, Y2]%, the standard range for sulfur content is [Z1, Z2]%; the standard range for the iron content of iron-containing materials is [A1, A2]%, the standard range for impurity element content is [B1, B2]%; the standard range for the content of each alloying element of an alloy is [C1, C2]%, etc., where X1, X2, Y1, Y2, Z1, Z2, A1, A2, B1, B2, C1, and C2 are exact values set according to product quality requirements. The test results are judged and an early warning mechanism is triggered if an abnormality occurs. The notification methods of the early warning mechanism include SMS (the SMS content contains the abnormal result details, sample number, and timestamp) and system pop-up window (the pop-up window displays the abnormal result data and possible impact analysis); S5. Preset batching rules in the encrypted information management system. Set barreling rules based on raw material type (such as coal, coke, iron-containing materials, solvents, alloys, etc.), supplier (distinguished by supplier encryption code), and batch (distinguished by batch encryption number). When samples are delivered to the barreling area, the system automatically identifies the sample information and barrels according to the batching rules. The system monitors the status of the sample barrels. When the number of samples in the barrel reaches the preset full barrel number (set according to the barrel capacity and sample specifications, such as a 50-liter barrel, for coal samples with smaller particle size, the full barrel number is set to 1), the system will automatically identify the sample information and barrel according to the batching rules. 00 kg; for block-shaped iron-containing materials, the full barrel quantity is set to 50 pieces, etc.), the operator is automatically reminded to clear the barrel. The barrel clearing reminder method includes displaying a striking prompt message on the operation terminal (the prompt message includes the barrel number, full barrel time, and sample type), issuing a voice alarm (the voice content is "Barrel [X] is full, please clear the barrel in time", X is the barrel number), and sending a reminder text message to the operator's mobile phone (the text message content is "The [sample type] sample barrel [X] you are responsible for is full, please clear the barrel as soon as possible, the full barrel time is [specific time]"); In the encryption rules for basic raw material information, the digital code after the supplier name is converted, the scrambled reorganization method of the raw material batch number, and the coding conversion method of the raw material origin information ensure the uniqueness and confidentiality of the information. The acquisition and conversion method of the dynamic encryption factor related to sample preparation ensures the dynamic and security of encryption. The encryption algorithm based on the hash function produces a unique encryption result each time encryption is performed. The encryption of the sample preparation process information covers the key operating parameters and personnel information in the sample preparation process, ensuring the information security of the sample preparation link. The various indicators of the test results are accurately measured to provide an accurate basis for product quality assessment. Blockchain encryption technology ensures that the test results cannot be tampered with. The triggering conditions of the early warning mechanism are based on preset precise quality standards. The scope and notification method ensure that relevant personnel can obtain abnormal information in time. The batching rules and barreling rules are precisely set according to the characteristics of the raw materials and management needs, which improves the efficiency and accuracy of sample management. The barrel cleaning reminder methods are diverse and contain detailed information, which is convenient for operators to respond in time. The real-time synchronization update of the sample preparation process database and the encrypted information management system ensures the timeliness and consistency of information. Enterprises can share part of the encrypted quality inspection data with suppliers based on the encrypted information recorded in the blockchain while ensuring information security. The shared data undergoes specific encryption conversion and only contains relevant information that can be viewed by suppliers (such as supplier product quality data, and does not contain other supplier information and sensitive information such as the company's internal production process).

[0024] Example 2 This embodiment also provides a method for controlling the entire process of quality inspection of incoming coal raw materials with multiple encryption. The specific operation steps are as follows: Step S1, sampling: Step S101: Establish an encrypted information management system, which has data storage, information exchange and encryption processing functions, and uses a high-strength encryption algorithm to ensure data security; Step S102: The sampling personnel use a handheld device equipped with an encryption program at the coal yard; for a batch of coal, the supplier name is "ABC Coal Company". According to the alphanumeric conversion rules, A is converted to 01, B is converted to 02, and C is converted to 03, resulting in the supplier name encryption code of "010203"; the raw material batch number is "20230510", and three random digits (such as 321 and 456) are inserted at the beginning and end respectively to become "32120230510456", which is then scrambled and reorganized (such as becoming "51045632120230"); the raw material origin is "Shanxi Datong", and the pinyin initials "SDDT" are taken and converted into hexadecimal code "53444454"; the handheld device generates a label containing this encrypted information, and the sampling personnel affix the label to the sealed bag containing the coal sample and upload the encrypted information to the encryption information management system in real time via the wireless network; Step S2, sample preparation: Step S201: The sample preparation device reads the encrypted label on the sealed bag and interacts with the encryption information management system to obtain encrypted information about the sampling process; the sample preparation start time is 10:30:20:123 milliseconds on June 15, 2023, which is converted to the digital code "20230615103020123" with an accuracy of milliseconds; the sample preparation device number is "SD-001" (a combination of ten digits and letters); the current operating parameters of the sample preparation device are: the device temperature is 30.5 degrees Celsius, which is converted to the three-digit code "0305" with an accuracy of 0.1 degrees Celsius; the device pressure is 0.55 MPa, which is converted to the four-digit code "0550" with an accuracy of 0.01 MPa; the device speed is 120 rpm, which is converted to the five-digit code "00120" with an accuracy of 1 rpm; Step S202: The sample preparation personnel number is "00010234" (eight digits). The sample preparation steps include a crushing operation with a crushing time of 120 seconds, a screening operation with a sieving mesh size of 100, and a grinding operation with a grinding time of 30 minutes. The sample preparation process information is encrypted using a SHA-256 hash function combined with the sampling step encryption information. The encrypted sample preparation information is stored in a sample preparation process database, which is synchronized and updated in real time with the encryption information management system. Step S3: Testing Step S301: The testing equipment tests the coal sample and obtains the test results. The coal has a calorific value of 5500.5 kcal / kg (accurate to 0.1 kcal / kg), an ash content of 15.25% (accurate to 0.01%), and a sulfur content of 0.850% (accurate to 0.001%). The encrypted information management system retrieves the encrypted information from the sampling and sample preparation steps, uses blockchain encryption technology to generate a blockchain data block containing all the information, generates a unique blockchain hash value for the test results, and stores it in the blockchain node. Step S302: The encrypted information management system sets preset standards for the coal raw materials: the calorific value standard range is [5000, 6000] kcal / kg, the ash content standard range is [10, 20]%, and the sulfur content standard range is [0.5, 1.5]%. The calorific value and ash content of this batch of coal samples are within the standard range, and the sulfur content is slightly higher than the standard upper limit. The system triggers an early warning mechanism and notifies the relevant quality management personnel via a text message (the text message content is "Sample number

[001] coal sample sulfur content is abnormal, the result is 0.850%, which is outside the standard range [0.5, 1.5]%, detection time 20230615110000 (timestamp)") and a system pop-up window (the pop-up window displays the abnormal sulfur content data of 0.850%, and the analysis may affect the increase of pollution emissions after combustion). Step S4: Automatic bucketing and reminder: Step S401: Preset batch grouping rules in the encrypted information management system. Bucketing rules are set based on the coal raw material type, the supplier encryption code "010203," and the batch encryption number "51045632120230." Coal samples from the same supplier and the same batch are assigned to the same bucket. When samples are delivered to the bucketing area, the system automatically identifies the sample information and buckets them according to the batch grouping rules. The buckets are labeled "005" and the full bucket threshold is preset to 100 kilograms (based on the bucket capacity and coal sample specifications). Step S402: When the amount of coal samples in the barrel reaches 100 kg, the system automatically issues a barrel-clearing reminder to the operator; a striking prompt message "Barrel 005 is full, please clear the barrel in time, coal sample information [supplier: 010203, batch: 51045632120230]" is displayed on the operation terminal, and a voice alarm "Barrel 005 is full, please clear the barrel in time" is issued, and a reminder text message is sent to the operator's mobile phone "The coal sample barrel 005 you are responsible for is full, please clear the barrel as soon as possible, the full barrel time is 20230615120000".

[0025] Example 3 This embodiment also provides a method for controlling and multi-encrypting the entire process of the incoming quality inspection of iron-containing materials. The specific operation steps are as follows: Step S1, sampling: Utilizing an established encrypted information management system; for iron-containing materials, the supplier name is "XYZ Mining Company," and the converted encryption code is "242526" (X corresponds to 24, Y corresponds to 25, and Z corresponds to 26); the raw material batch number "20230605" is converted to "78920230605123" after inserting random numbers and scrambling them; the raw material origin is "Hebei Tangshan," and the pinyin initials "HBTS" are converted to the hexadecimal code "48425453"; the handheld device generates a label and uploads the encrypted information; Step S2, sample preparation: The sample preparation equipment reads the label to obtain the encrypted sampling information; the sample preparation start time is 14:15:30:567 milliseconds on June 20, 2023, which is converted to "20230620141530567"; the sample preparation equipment number is "TJ-002"; the equipment temperature is 35.2 degrees Celsius (code "0352"), the pressure is 0.60 MPa (code "0600"), and the speed is 150 rpm (code "00150"); the sample preparation personnel number is "00020345", and the crushing time in the sample preparation step is 90 seconds, the screening mesh size is 80 mesh, and the grinding time is 45 minutes; the information is stored after being encrypted using a hash function; Step S3, testing step: Test results: Iron content is 65.30% (accurate to 0.01%), impurity element content (e.g. silicon content is 0.500%, accurate to 0.001%); generate blockchain data blocks and hash values; preset iron content standard range is [60,70]%, impurity element standard range is [0.3,1.0]%; the iron content of this batch is normal, silicon content is close to the upper limit, the system triggers an alert, the text message content is "Sample number

[002] Iron-containing material silicon content is close to the upper limit, the result is 0.500%, standard range [0.3,1.0]%, detection time 20230620150000", and a pop-up window displays silicon content data and impact analysis; Step S4: Automatic bucketing and reminder: Preset batching rules divide ferrous materials into barrels according to their type, supplier, and batch information. The barrel is labeled "006" and the full barrel threshold is 50 pieces (based on material specifications). When the barrel is full, the operating terminal prompts "Barrel 006 is full, ferrous material information [supplier: 242526, batch: 78920230605123]", and a voice alarm and mobile phone text message remind the operator to clear the barrel.

[0026] Example 4 This embodiment also provides a method for controlling and multi-encrypting the entire process of quality inspection of alloy raw materials entering the site. The specific operation steps are as follows: Step S1, sampling: The encrypted information management system is running; the name of the alloy raw material supplier, "DEF Alloy Factory", is encrypted to "040506"; the batch number, "20230701", becomes "45620230701789" after processing; the place of production, "Shenyang, Liaoning", is coded as "4C4E5359"; the handheld device is used to upload the information as before; Step S2, sample preparation: The sample preparation equipment reads information: the sample preparation start time is 9:20:10:234 milliseconds on July 5, 2023 ("20230705092010234"), the equipment number is "LN-003", the equipment temperature is 32.0 degrees Celsius ("0320"), the pressure is 0.45 MPa ("0450"), and the speed is 100 rpm ("00100"); the sample preparation personnel number is "00030456", the sample preparation steps include crushing time of 150 seconds, screening mesh size of 120 mesh, and grinding time of 60 minutes; the encrypted storage information; Step S3, testing step: Test results: content of a certain alloying element (e.g., nickel content of 15.05%, accurate to 0.01%), etc.; generate blockchain-related information; the preset nickel content standard range is [10, 20]%, and the nickel content of this batch is normal; if other abnormal element contents trigger an alert, the notification method is the same as before; Step S4: Automatic bucketing and reminder: The barrels are divided into barrels according to the rules, and the barrels are marked with "007". The full barrel threshold is set according to the specifications of the alloy raw materials (such as 80 kg); when the barrel is full, the operator is reminded, and the prompt information includes the barrel number, raw material information and the time when the barrel is full.

[0027] The data of the manual sampling without encryption or simple encryption in the prior art are compared. Taking the coal raw material in Example 1 as an example, the comparison results of the data of the present invention and the prior art are shown in Table 1 below: Table 1 From the data comparison, it can be seen that the present invention is obviously superior to the existing technology in terms of information confidentiality, data authenticity, quality inspection efficiency, timeliness of exception handling and enterprise cost control, and has significant innovation and advantages.

[0028] The present invention completely isolates sensitive information in the sampling, sample preparation and testing links through triple encryption and unique encryption technology application, effectively preventing information leakage and protecting corporate trade secrets.
