Abstract

The present invention discloses a digital interaction method and system for metering detection data, and relates to the technical field of metering interaction. After acquiring metering acquisition data of target power equipment, the present invention first constructs a reference conversion sequence for conversion, and performs conversion processing on the real-time metering acquisition data according to the reference conversion sequence.

Whenever a new reference conversion sequence is obtained, it is subjected to an AND operation with the mapping sequence to obtain a corresponding transformation sequence, thereby ensuring the dynamics and complexity of each group of mapping sequences, so that the reference conversion sequence subjected to the AND operation with each group of mapping sequences is in dynamic change, and further ensuring the security of the metering detection data during transmission.

Description

Technical Field

[0001] The present invention relates to the field of metrology interaction technology, and in particular to a metrology detection data digital interaction method and system. Background Art

[0002] With the rapid development of intelligent and digital power systems, the measurement and testing data of power equipment plays a vital role in the operation, management, and maintenance of power systems. These measurement and testing data contain key parameter information such as voltage, current, and power of power equipment, which is indispensable for evaluating the operating status of power equipment, achieving accurate power allocation, and fault diagnosis.

[0003] In the current field of power technology, in order to achieve more efficient management and monitoring of power equipment, it is often necessary to transmit metering and detection data to the cloud for storage and analysis. However, the data transmission process from power equipment to the cloud faces many security risks.

[0004] Currently, a common way to ensure the security of measurement and testing data transmission is to use key technology. By using a key to encrypt the measurement and testing data, only the recipient (cloud server, etc.) with the correct key can decrypt and read the data. This method can prevent data from being obtained and tampered with by unauthorized third parties to a certain extent.

[0005] However, relying solely on keys to ensure the security of power equipment metering and detection data transmission has obvious limitations. On the one hand, the key itself is at risk of being stolen or cracked. With the continuous development of computer technology, hacker attack methods are becoming increasingly sophisticated. Once the key is leaked, the entire data transmission security line will collapse instantly. Malicious attackers can easily decrypt and obtain sensitive metering and detection data of power equipment, which may lead to the leakage of power system operation information, posing a serious threat to the stable operation of the power system.

[0006] On the other hand, fixed key mechanisms lack flexibility and dynamic adaptability. If the same key is used over a long period of data transmission, attackers have more time and opportunities to analyze and crack the key. Once the key of a device is cracked, the data security of the entire system may be affected.

[0007] In order to solve the above problems, the present invention proposes a solution. Summary of the Invention

[0008] The purpose of the present invention is to provide a digital interactive method and system for measurement and detection data, in order to solve the problems raised in the above background technology;

[0009] The purpose of the present invention can be achieved through the following technical solutions:

[0010] A digital interactive method for measurement and detection data includes the following steps:

[0011] Step 1: After receiving the metering data of the target power equipment at the current moment, the metering interaction module constructs the current benchmark conversion sequence according to the preset construction rules;

[0012] Step 2: converting the metering data of the target power equipment at the current moment according to the preset conversion generation rules based on the current reference conversion sequence to generate the current metering conversion sequence, and transmitting the metering conversion sequence to the remote receiving module;

[0013] Step 3: After receiving the transmitted metering conversion sequence, the remote receiving module restores it to obtain metering acquisition data of the target power equipment at the current moment, and stores the metering acquisition data.

[0014] Furthermore, the construction rules of the current benchmark conversion sequence are as follows:

[0015] S11: Label each character of the four-digit binary number 0000 that constitutes the digital character 0 as A1, A2, A3, and A4 in order from left to right;

[0016] S12: In the order of characters A1, A2, A3, and A4, concatenate A1 and A2, A2 and A3, and A3 and A4 to obtain three feature combinations, then perform a deduplication operation on the obtained three feature combinations, and recalibrate the remaining feature combinations after deduplication as standard combinations of character 0;

[0017] S13: Obtain all standard combinations of characters 1, 2, ..., 15 in sequence according to S11 to S12;

[0018] S14: Generate the first interaction list C1, the second interaction list C2 and the third interaction list C3 at the current moment according to the preset generation steps:

[0019] S15: Extract all elements of the first interaction list C1 in ascending order of index, and concatenate all extracted elements in the order of element extraction to obtain the element sequence of the first interaction list C1. Similarly, obtain the element sequences of the second interaction lists C2 and C3 in sequence.

[0020] S16: Concatenate the element sequences of the first interaction lists C1, C2, and C3 in the order of C1, C2, and C3 to obtain a reference conversion sequence at the current moment.

[0021] Furthermore, in S14, the steps for generating the first interaction list C1, the second interaction list C2, and the third interaction list C3 at the current moment are as follows:

[0022] S141: creating a first interaction list B1, a second interaction list B2, and a third interaction list B3 at the current moment;

[0023] S142: If the number of standard combinations of character 0 obtained after deduplication in S12 is 1, add the standard combination of character 0 to the first interaction list B1;

[0024] If the number of standard combinations of character 0 obtained after deduplication in S12 is 2, then all standard combinations of character 0 are added to the second interactive list B2, wherein all standard combinations of character 0 are added to the second interactive list B2 in the order in which each standard combination is concatenated;

[0025] If the number of standard combinations of character 0 obtained after deduplication in S12 is 3, then all standard combinations of character 0 are added to the third interactive list B3. When adding all standard combinations of character 0 to the third interactive list B3, they are added to the third interactive list B3 in the order in which each standard combination is concatenated.

[0026] S143: According to S142, determine whether the number of standard combinations of characters 1, 2, ..., 15 obtained after deduplication is 1, 2, or 3, and add all standard combinations of corresponding characters to the corresponding interaction lists according to the determination results. After all standard combinations of character 15 are added, the final first interaction list, second interaction list, and third interaction list are obtained, which are re-marked as C1, C2, and C3 respectively.

[0027] Furthermore, the metering interaction module transmits the metering conversion sequence at the current moment to the remote receiving module, and deletes the reference conversion sequence at the current moment after the transmission is completed.

[0028] A digital interactive system for measurement and detection data, comprising:

[0029] The metering acquisition module is used to collect the detection data of several metering parameters of the target power equipment in real time;

[0030] The metering interaction module is used to construct a real-time reference conversion sequence after receiving the real-time metering data collected by the target power equipment, and convert the real-time metering data collected by the target power equipment according to the constructed real-time reference conversion sequence and preset conversion rules to generate a real-time metering conversion sequence;

[0031] The remote receiving module is used to receive, restore and store the real-time measurement conversion sequence.

[0032] Beneficial effects of the present invention:

[0033] After acquiring the metering data collected by the target power equipment, the present invention first constructs a reference conversion sequence for conversion, and then performs conversion processing on the real-time metering data according to the reference conversion sequence. The construction of the reference conversion sequence is based on the character composition type of the four-bit binary numbers of the digital characters 0 to 15. In the conversion processing stage, the character type to be eliminated from the reference conversion sequence is determined according to the frequency of different two-bit binary numbers in each mapping sequence, thereby obtaining a new reference conversion sequence. Each time a new reference conversion sequence is obtained, it is subjected to an AND operation with the mapping sequence to obtain a corresponding transformation sequence. Through this approach, the dynamics and complexity of each group of mapping sequences are guaranteed, so that the reference conversion sequence subjected to the AND operation with each group of mapping sequences is in dynamic change, further ensuring the security of the metering detection data during transmission.

[0034] After completing the measurement detection data transmission, the measurement interaction module of the present invention will delete the real-time reference conversion sequence to ensure the security of the measurement detection data transmission. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] 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 any creative efforts shall fall within the scope of protection of the present invention.

[0038] like Figure 1 As shown, a digital interaction method and system for measurement detection data includes a measurement acquisition module, a measurement interaction module and a remote receiving module;

[0039] The metering acquisition module is used to collect detection data of several metering parameters of the target power equipment in real time, where the metering parameters include voltage, current, resistance, power, load loss and no-load loss. In this application, the target power equipment is a transformer;

[0040] The metering acquisition module collects the detection data of several metering parameters of the target power equipment in real time and generates real-time metering acquisition data of the target power equipment based on the detection data, and transmits the metering acquisition data to the metering interaction module;

[0041] The metering interaction module is configured to construct a real-time reference conversion sequence after receiving the metering data collected by the real-time target power equipment, and convert the metering data collected by the real-time target power equipment according to the constructed real-time reference conversion sequence and preset conversion rules to generate a real-time metering conversion sequence;

[0042] Taking the metering data of the target power equipment at the current moment received by the metering interaction module as an example, after receiving the metering data of the target power equipment transmitted at the current moment, the metering interaction module first constructs the reference conversion sequence at the current moment according to the preset construction rules. The construction rules are as follows:

[0043] S11: Label each character of the four-digit binary number 0000 that constitutes the digital character 0 as A1, A2, A3, and A4 in order from left to right;

[0044] S12: In the order of characters A1, A2, A3, and A4, concatenate A1 and A2, A2 and A3, and A3 and A4 to obtain three feature combinations, then perform a deduplication operation on the obtained three feature combinations, and recalibrate the remaining feature combinations after deduplication as standard combinations of character 0;

[0045] S13: Obtain all standard combinations of characters 1, 2, ..., 15 in sequence according to S11 to S12;

[0046] S14: Generate the first interaction list C1, the second interaction list C2, and the third interaction list C3 at the current moment according to the preset generation steps. The generation steps are as follows:

[0047] S141: creating a first interaction list B1, a second interaction list B2, and a third interaction list B3 at the current moment;

[0048] S142: If the number of standard combinations of character 0 obtained after deduplication in S12 is 1, add the standard combination of character 0 to the first interaction list B1;

[0049] If the number of standard combinations of character 0 obtained after deduplication in S12 is 2, then all standard combinations of character 0 are added to the second interactive list B2, wherein all standard combinations of character 0 are added to the second interactive list B2 in the order in which each standard combination is concatenated;

[0050] If the number of standard combinations of character 0 obtained after deduplication in S12 is 3, then all standard combinations of character 0 are added to the third interactive list B3. When adding all standard combinations of character 0 to the third interactive list B3, they are added to the third interactive list B3 in the order in which each standard combination is concatenated.

[0051] S143: According to S142, the number of standard combinations of characters 1, 2, ..., 15 obtained after deduplication is determined to be 1, 2, or 3, and all standard combinations of the corresponding characters are added to the corresponding interaction lists according to the determination results. After all standard combinations of character 15 are added, the final first interaction list, second interaction list, and third interaction list are obtained and re-labeled as C1, C2, and C3 respectively.

[0052] S15: Extract all elements of the first interaction list C1 in ascending order of index, and concatenate all extracted elements in the order of element extraction to obtain the element sequence of the first interaction list C1. Similarly, obtain the element sequences of the second interaction lists C2 and C3 in sequence.

[0053] S16: splicing the element sequences of the first interaction lists C1, C2 and C3 in the order of C1, C2, C3 to obtain the reference conversion sequence at the current moment;

[0054] Then, the metering interaction module performs a security conversion on the metering data of the target power equipment received at the current moment according to the preset conversion rules based on the current benchmark conversion sequence. The conversion rules are as follows:

[0055] S21: performing binary conversion on the metering data collected by the target power equipment received at the current moment, and marking the converted data as data to be converted;

[0056] S22: Specify a cutting step size of 4 and cut the data to be converted from left to right. During the cutting process, each four characters are used as a group of mapping arrays to obtain a number of mapping arrays. According to the position of each group of mapping arrays in the data to be converted before cutting, all the obtained group mapping arrays are marked as D1, D2, ..., Dd from left to right, where d ≥ 1.

[0057] S23: Extract all mapping arrays with subscripts less than or equal to P1 from the mapping arrays D1, D2, ..., Dd, and concatenate all the extracted mapping arrays in ascending order of subscripts to obtain a mapping sequence E1, where P1 is a preset extraction standard quantity group;

[0060] S251: taking every two characters in the mapping sequence E1 as a group of updated reference arrays from left to right to obtain a plurality of groups of updated reference arrays;

[0061] S252: Count the number of update reference arrays consistent with the two-digit binary number 00 in all the group update reference arrays obtained in S251, and mark it as the frequency value F1 of the two-digit binary number 00;

[0062] S253; according to S252, the frequency quantities F2, F3 and F4 of the two binary numbers 01, 10 and 11 are obtained in sequence;

[0063] S254: Select the two binary digits corresponding to the frequency quantity with the largest value from the frequency quantities F1, F2, F3, and F4 as the updated binary array of the mapping sequence E1;

[0064] S26: According to a preset elimination update rule, two characters are eliminated from the current reference conversion sequence to obtain a new reference conversion sequence at the current moment. The elimination update rule is as follows:

[0065] S261: Mark the two characters constituting the updated binary array of the mapping sequence E1 as H1 and H2 respectively from left to right;

[0066] S262: From left to right, remove the first character that is consistent with characters H1 and H2 from all characters in the current reference conversion sequence, and then use the conversion sequence after the removal as the new reference conversion sequence for the current moment. It should be noted that if the total number of characters in the new reference conversion sequence for the current moment is less than or equal to 2, the current reference conversion sequence obtained in S16 is used as the new reference conversion sequence for the current moment.

[0067] S27: According to steps S23 to S25, all group mapping arrays with subscripts less than or equal to 2P1 are extracted from all group mapping arrays remaining after extraction in S23, thereby obtaining a mapping sequence E2;

[0068] Perform an AND operation on the mapping sequence E2 and the new reference conversion sequence at the current moment to obtain a transformation sequence of the mapping sequence E2;

[0069] S28: According to S23 to S26, a plurality of mapping sequences are obtained based on all the remaining group mapping arrays after extraction. All the mapping sequences are labeled E3, E4, ..., Ee in the order in which each mapping sequence is obtained, where e ≥ 1. According to S27, after each mapping sequence is obtained, a new reference conversion sequence at the current moment is obtained according to S26, and a reference conversion sequence of the corresponding mapping sequence is also obtained.

[0070] It should be noted here that the generation of each mapping sequence is based on all the remaining group mapping arrays after the generation of the previous mapping sequence. For example, the generation of mapping sequence E3 is to extract mapping arrays with subscripts less than or equal to 3P1 from all the remaining group mapping arrays after the generation of mapping sequence E2;

[0071] It should be noted here that, in the process of extracting P1 mapping arrays from the mapping arrays D1, D2, ..., Dd, if the number of remaining mapping arrays is less than P1, a group of mapping sequences is also obtained based on all the remaining group mapping arrays;

[0072] S29: In the order of mapping sequences E1, E2, ..., Ee, the reference conversion sequences of mapping sequences E1, E2, ..., Ee are concatenated to obtain the metrology conversion sequence at the current moment;

[0073] The metering interaction module transmits the metering conversion sequence at the current moment to the remote receiving module, and deletes the reference conversion sequence at the current moment after the transmission is completed;

[0074] The remote receiving module is used to securely store the detection data of several metering parameters of the target power equipment at the remote end. After receiving the transmitted metering conversion sequence at the current moment, the remote receiving module first constructs the reference conversion sequence at the current moment according to the same construction rules, and then restores the received metering conversion sequence at the current moment according to the reference conversion sequence at the current moment to obtain the metering collection data of the target power equipment at the current moment, and stores the metering collection data.
