Description

Technical Field

[0001] The present invention relates to the field of secure information transmission, and in particular to a method for secure transmission of power field fault information. Background Art

[0002] Grid dispatching and operation is an important department for the safe and stable operation and management of the grid. The original telephone ordering and permission work mode can no longer adapt to the high-intensity and high-pressure work status of modern grid dispatching. At present, when grid operation and maintenance personnel are working on site, they need to perform standardized operations and troubleshoot according to the contents of the operation ticket. They dial the virtual seat through the intercom terminal. The virtual seat generates a time-handling operation ticket according to the on-site conditions and issues task execution instructions to the operation and maintenance personnel through the dispatching platform. During the on-site maintenance process, the operation and maintenance personnel perform routine operation and maintenance operations according to the operation ticket instructions.

[0003] Since the same dispatching system needs to correspond to communications and dispatching in multiple areas, when there are multiple lines of operation and maintenance operations at the same time, the virtual dispatching desk needs to divert on-site tasks to prevent information congestion; the existing virtual dispatching desk cannot divert and handle according to the request information from the on-site end, and the image data sent back from the on-site is not securely and confidentially operated, resulting in the possibility of information being tampered with and stolen, posing a hidden danger to power operation and maintenance. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that the existing virtual dispatching desk cannot divert and process the on-site information and the security of the on-site feedback information cannot be guaranteed. A method for secure transmission of power on-site fault information is proposed. By establishing an exclusive channel between the on-site business terminal and the virtual dispatching desk, it can be ensured that each communication line is relatively independent and does not interfere with each other, thereby preventing information congestion; at the same time, an encryption password is used to encrypt the collected information at the business terminal, thereby ensuring the security of information transmission.

[0005] In order to achieve the above technical objectives, the present invention provides a technical solution, which is a method for securely transmitting power field fault information, comprising the following steps:

[0006] S1. After biometric identification, the business terminal opens a dedicated channel and establishes communication with the virtual dispatching station;

[0007] S2. The business terminal obtains the on-site fault picture, annotates and extracts the features of the picture, packages it into the first encryption block with the encryption password, and sends it to the virtual dispatching console through a dedicated channel;

[0008] S3. After the virtual dispatching station decrypts the first encrypted block, it restores the image information of the first encrypted block to obtain an on-site fault image, analyzes the on-site fault image to determine the fault level, and implements a corresponding response strategy according to the fault level.

[0009] In this solution, when the business terminal establishes contact with the virtual dispatching desk through the State Grid's general channel for the first time, the virtual dispatching desk identifies the identity information of the on-site operation and maintenance personnel and allocates the corresponding exclusive channel according to the identity information. After that, the information transmission between the business terminal and the dispatching platform is carried out in the exclusive channel, which prevents information congestion. The business terminal collects the fault pictures of the on-site equipment and sends them to the virtual dispatching desk for fault judgment after encryption, which ensures the security of information transmission. According to the fault judgment results, the corresponding fault handling strategy is generated. For example, transformer fire, oil leakage, etc. Transformer fire is a first-level response, and a safety alarm needs to be issued in time to remind on-site personnel to evacuate and notify upstream and downstream circuit departments to perform power-off operations. Transformer oil leakage is a second-level response and requires power outage for maintenance.

[0010] Preferably, in S1, the service terminal opens an exclusive channel after biometric identification, which includes the following steps: extracting biometric information through the biometric identifier of the service terminal, sending the biometric information to the virtual dispatching desk through the State Grid's general channel, the virtual dispatching desk opens an exclusive channel according to the authority level of the biometric information, and sends the exclusive channel code and splicing rules to the service terminal, and the service terminal performs channel conversion according to the exclusive channel code.

[0011] In this solution, different identity levels correspond to different exclusive channels; the business terminal establishes contact with the virtual dispatching console according to different exclusive channels, and the business terminal uses corresponding splicing rules to encrypt information.

[0012] Preferably, S2 comprises the following steps:

[0013] The service terminal obtains image information of the faulty device through a camera module, obtains a high-definition target sub-image by manually gridding, selecting and marking the faulty area of ​​the image, extracts features from the high-definition target sub-image of the marked area and digitizes it to obtain first label information;

[0014] Performing an artificial voice description on the first tag information, extracting voiceprint information and text information of the artificial voice description; and using the voiceprint information as an encrypted password;

[0015] The first label information and the text information are respectively transcoded into a binary number L1 and a binary number L2, and the binary codes are spliced ​​into a binary chain block D using a splicing rule;

[0016] The binary chain block D is encrypted using an encryption password to obtain a first encrypted block.

[0017] In this scheme, firstly, the on-site equipment image is obtained, and then the fault area is manually marked. After the fault area is cut in a gridding manner, a high-definition target sub-image is obtained, which greatly reduces the amount of data. The high-definition target sub-image contains its position information in the corresponding equipment image, and the high-definition target sub-image is transcoded into a binary number L1 for easy encryption and transmission; the on-site personnel need to give a voice description of the faulty equipment information, extract the voiceprint information of the voice description, and generate text information according to the voice description, and transcode the text information into a binary number L2, and use the voiceprint information as the encryption password, so that the encryption password is uniquely determined; the binary number L1 and the binary number L2 are spliced ​​into a binary chain block D using the splicing rule obtained for the first time, which is equivalent to an internal encryption, and then the binary chain block D is encrypted using the encryption password to obtain the first encrypted block, and the first encrypted block is sent to the virtual dispatching console. In the process of information transmission, if there is information interception or theft, since the first encrypted block has been encrypted twice, its encryption method and rules are independent and private, which greatly increases the difficulty of password cracking and further guarantees the security of information transmission.

[0018] Preferably, S3 comprises the following steps:

[0019] After the virtual dispatching station obtains the first encrypted block, it uses the corresponding biometric information to decrypt the first encrypted block to obtain a binary chain block D;

[0020] The splicing rule is called to split and restore the binary chain block D to obtain two independent binary numbers L1 and L2; the binary numbers L1 and L2 are decoded respectively to obtain the first label information and the text information;

[0021] The image template corresponding to the faulty device is retrieved, and the faulty area and the high-definition target sub-image are located and restored on the image template according to the first label information.

[0022] In this solution, the first encrypted block is decrypted by the identity information of the corresponding on-site personnel in the virtual dispatch console to obtain the binary chain block D, and then the corresponding splicing rule is used to restore the binary chain block D to obtain the first label information and text information. The first label information is transcoded to obtain a high-definition target sub-image, and the image template of the corresponding faulty equipment is retrieved. The faulty area is located and displayed according to the position information of the high-definition sub-image relative to the image of the faulty equipment.

[0023] Preferably, the splicing rule is:

[0024] The longest sequence length of binary number L1 and binary number L2 is taken as the reference sequence length, and 0 is added bit by bit to make the sequence size of the short binary number equal to the reference sequence length, and then the binary chain block D is obtained by bit cross-combination.

[0025] Preferably, the biometric information includes fingerprint information or voiceprint information, or:

[0026] Fingerprint information or a combination of fingerprint and voiceprint information.

[0027] Beneficial effects of the present invention: The present invention designs a method for secure transmission of power field fault information. By establishing an exclusive channel between the field business terminal and the virtual dispatching console, it can ensure that each communication line is relatively independent and does not interfere with each other, thereby preventing information congestion; at the same time, encryption passwords and splicing rules are used to double encrypt the collected information at the business terminal, thereby ensuring the security of information transmission.
