From historical experience, these two tasks have exceeded the regular duties of the team, but because they are directly related to the success of the guarantee mission, the team needs to invest a lot of extra manpower to organize materials and information, which not only increases the workload, but also affects the efficiency of on-site operation and maintenance, posing a hidden danger to the safety of the power grid.

[0003] Currently, in terms of personnel management, forms are usually used to collect information. There is a lack of data interaction between multiple related systems, which leads to repeated entry and maintenance of power supply guarantee personnel information, which in turn leads to data silos and affects the accuracy and timeliness of information.

[0090] In this embodiment, the specific functions of the intelligent management badge are as follows:

[0091] First, as Figure 2 As shown in the figure, the smart management badge uses NFC power supply and NFC communication technology; the smart management badge has a built-in NFC chip, which serves as both a power receiving end (NFC power receiving module) and a data communication module (NFC communication module). When the badge is close to a mobile terminal equipped with NFC function, the NFC chip obtains power from the mobile terminal or charging device through the principle of electromagnetic induction, and provides working power for other circuits in the badge. At the same time, the NFC chip is also responsible for wireless transmission of data, sending the information in the badge (such as personnel identity, authority, etc.) to the mobile terminal and further sending it to the service platform as needed to achieve real-time update and synchronization of data.

[0092] This embodiment provides a working principle of intelligent management of work badges for power supply guarantee personnel, which is as follows:

[0093] (1) Power supply process

[0094] Proximity induction: When the smart management badge is close to a mobile terminal or dedicated charging device equipped with NFC function, the NFC chip enters the electromagnetic induction range.

[0095] Energy acquisition: Through the principle of electromagnetic induction, the NFC chip obtains electrical energy from the electromagnetic field emitted by the mobile terminal or charging device. This process does not require physical contact and relies on the short-range wireless communication characteristics of NFC technology.

[0096] Power management: The power management system inside the badge detects and converts the received electrical energy into voltage and current suitable for the operation of other circuits to ensure stable power supply.

[0097] Power supply confirmation: The power management system monitors the power input. Once it is confirmed that the power is stable and sufficient to support the normal operation of the ID card, it is considered that the power supply is normal and is ready to enter the data transmission stage.

[0098] Confirm the normal power supply algorithm:

[0099] Threshold judgment: Set the minimum threshold of power input. The power management system continuously monitors the power input. When the input power exceeds this threshold and lasts for a certain period of time (such as a few seconds), it is judged as normal power supply.

[0100] Stability detection: After initially judging that the power supply is normal, continue to monitor the power fluctuation to ensure that the power supply is stable without abnormal jitter, and further confirm the power supply status.

[0101] (2) Communication process

[0102] Establishing a connection: After confirming that the power supply is normal, the NFC chip initializes the communication link with the mobile terminal or service platform and prepares for data transmission.

[0103] Identity verification: To ensure data security, the ID card first sends an identity verification request to the mobile terminal or service platform, including encrypted identity information and possible dynamic verification code to verify the authenticity of the ID card.

[0104] Data transmission: After identity authentication is passed, the NFC chip starts to send the information stored in the work badge, such as personnel identity, authority data, etc. This data may be encrypted to ensure security during transmission.

[0105] Data reception and confirmation: After the mobile terminal or service platform receives the data, it decrypts it (if necessary) and verifies the integrity and correctness of the data, and then sends a reception confirmation signal to the work badge.

[0106] Data synchronization and update: Based on the received data, the service platform or mobile terminal synchronizes or updates the data to ensure the timeliness and accuracy of the information.

[0107] (3) Data transmission and integrity and security assurance algorithms

[0108] Encryption algorithm: Use encryption algorithms such as AES and RSA to encrypt the transmitted data to ensure that the data is not illegally intercepted and tampered with during the transmission process.

[0109] Data verification: Use a hash algorithm (such as SHA-256) to generate a hash value for the data and include this hash value when transmitting. After receiving the data, the receiver recalculates the hash value and compares it with the transmitted hash value to verify the integrity of the data.

[0110] Error retransmission mechanism: If an error or loss occurs during data transmission, the error is detected through a defined protocol and the sender is asked to retransmit until the data is received correctly.

[0111] Security authentication: Perform two-way identity authentication before data transmission, using digital certificates or pre-shared keys to ensure the legitimacy of the identities of both parties in communication and prevent man-in-the-middle attacks.

[0112] The specific algorithm is as follows:

[0113] SecureDataTransfer(Data,Key_AES,Key_RSA,HashFunc,Cert,Protocol)->EncryptedData,Hash,Ack

[0114] in:

[0115] Data: The original data to be transmitted.

[0116] Key_AES: key of AES encryption algorithm.

[0117] Key_RSA: key pair (public key / private key) of RSA encryption algorithm.

[0118] HashFunc: Hash function, such as SHA-256.

[0119] Cert: digital certificate or pre-shared key, used for identity authentication.

[0120] Protocol: A protocol that defines error detection, retransmission mechanisms, and data transmission processes.

[0121] EncryptedData: encrypted data.

[0122] Hash: Hash value of data.

[0123] Ack: Receive confirmation signal.

[0124] (4) Algorithm steps and parameter tuning

[0125] Data encryption: Use Key_AES to symmetric encrypt Data and generate EncryptedData.

[0126] Parameter tuning: Select the appropriate AES key length (such as 128 bits, 192 bits, or 256 bits) and encryption mode (such as CBC, GCM, etc.), and make trade-offs based on data sensitivity and performance requirements.

[0127] Data Hashing: Apply HashFunc to calculate the hash value Hash on Data.

[0128] Parameter tuning: Choose a suitable hash function, such as SHA-256 or the more secure SHA-3 series, based on data integrity and performance requirements

[0129] Authentication: Use Cert for two-way authentication to ensure the legitimacy of the identities of both communicating parties.

[0130] Parameter tuning: Select an appropriate authentication method based on security requirements, such as the TLS / SSL protocol based on digital certificates or a pre-shared key authentication mechanism.

[0131] Data transmission: Send the EncryptedData and Hash together to the receiver.

[0132] Parameter tuning: Optimize the transmission protocol, including packet size, transmission rate, error detection and retransmission mechanism, to improve transmission efficiency and reliability.

[0133] Acknowledgment & Error Handling: After receiving the data, the receiver recalculates the hash value of EncryptedData and compares it with the sent Hash to verify the data integrity. If the data is correct, an Ack confirmation signal is sent; if the data is wrong or lost, the sender is required to retransmit according to the mechanism defined by the Protocol.

[0134] Parameter tuning: Adjust the retransmission strategy (such as the number of retransmissions, retransmission interval, etc.) and the sensitivity of the error detection mechanism to balance transmission efficiency and reliability.

[0135] Second, as Figure 3 As shown in the figure, the intelligent management badge integrates the ink screen technology. This badge uses a low-power ink screen as the information display interface; the ink screen is composed of countless tiny black and white capsules, each of which contains black and white particles. The movement of the particles is controlled by the electric field to display different colors. When data is written to the ink screen, the electric field changes the distribution of the particles in the capsule, thereby displaying the corresponding information. Since the ink screen consumes almost no power when displaying static images, the badge can keep the content displayed for a long time after the data is written, without the need for additional power supply.

[0136] It can be seen that the intelligent management badge for power supply guarantee personnel provided by the present invention has the following advantages over the existing personnel management methods:

[0137] First, NFC power supply + NFC communication integration technology

[0138] The smart management badge innovatively uses NFC (near field communication) power and communication technology. Through NFC technology, the badge can obtain power from a mobile terminal equipped with NFC function and transmit data at the same time, without the need for a built-in battery, thus greatly reducing the size and weight of the badge and improving portability and management efficiency.

[0139] It not only solves the problem of regular battery replacement for most similar work badges, but also enables fast and secure data transmission through NFC communication, avoiding the inconvenience of traditional wired connections.

[0140] Second, integrated ink screen technology

[0141] The smart management badge integrates power-free ink screen technology. Once the data is written into the ink screen, the screen can keep displaying the content for a long time without additional power supply, which greatly extends the service life of the badge and reduces energy consumption, and reduces the trouble of frequently changing the content of traditional badges.

[0142] Ink screen technology not only provides a clear display effect, but also significantly reduces the power consumption of the ID card, allowing the ID card to display necessary information stably and persistently in a variety of environments.

[0143] Third, wireless power supply and data transmission of mobile terminals

[0144] Wireless power supply and wireless data transmission can be realized through the equipped mobile terminal (such as smart phone or dedicated PDA). The user only needs to bring the badge close to the mobile terminal to automatically complete the power supply and data exchange.

[0145] This wireless interaction method not only simplifies the operation process, but also improves the efficiency and security of data transmission. At the same time, the mobile terminal can also read the work badge data in real time, and compare and synchronize it with the data on the service platform to ensure the accuracy and consistency of the data.

[0146] Example 4

[0147] The present embodiment provides an intelligent management system for power supply support personnel, including any one of the intelligent management badges for power supply support personnel in the above embodiments; specifically, it also includes: a mobile terminal and a service platform; wherein, data can be transmitted between the intelligent management badge, the mobile terminal and the service platform, so as to realize synchronization and update of power supply support personnel information; wherein, the mobile terminal can also wirelessly charge the intelligent management badge through NFC technology.

[0148] like Figure 4 As shown in the figure, this management system is composed of a service platform, a mobile APP and an intelligent management badge; they jointly realize the comprehensive management of the intelligent management badge, specifically combined with Figure 5 As shown, the specific implementation includes:

[0149] First, the service platform is built based on cloud computing and big data technology. It is responsible for storing, processing and analyzing all data uploaded by smart management badges. The service platform protects data security through secure encryption technology to ensure that information is not leaked. Managers can view badge information, personnel location, task status, etc. through the service platform to achieve comprehensive monitoring and management of security personnel. The core technology of the system is data security management. Regarding data security, the implementation measures are as follows:

[0150] (1) Hardware-level encryption and identity authentication

[0151] Smart management badges have built-in security chips: Each smart management badge has a built-in high-performance security chip, which is not only responsible for NFC communication, but also integrates a hardware encryption module. This means that the data is encrypted before leaving the badge, and even if the badge is lost or illegally obtained, the sensitive information in it cannot be directly read.

[0152] Public Key Infrastructure (PKI): Using the PKI system, each badge is assigned a unique public and private key pair. The public key is used to encrypt data, and the private key is securely stored in the security chip of the badge for decryption and signing to ensure the authenticity and integrity of the data.

[0153] (2) End-to-end encrypted communication

[0154] TLS / SSL protocol: The communication between the service platform and the smart management badge is encrypted using the TLS / SSL protocol to ensure that data is not eavesdropped or tampered with during transmission. Even if the network is attacked by hackers, the data can be transmitted securely.

[0155] VPN tunnel: For particularly sensitive data transmission, a VPN tunnel can be established to further enhance the security of communications and ensure that data is as secure when transmitted over a public network as it is in a private network.

[0156] (3) Data encryption storage

[0157] Database encryption: The database on the service platform uses transparent data encryption technology. Even if the database is illegally accessed, the stored data cannot be directly read. At the same time, additional field-level encryption is performed on sensitive fields (such as name, ID number, etc.).

[0158] Key management: Establish a strict key management system and use hardware security modules (HSM) or key management services (KMS) to generate, store and manage encryption keys to ensure the security and non-tamperability of the keys.

[0159] (4) Access Control and Auditing

[0160] Fine-grained permission management: Set different access permissions based on the roles and responsibilities of managers to ensure that only authorized personnel can access specific data.

[0161] Operation log audit: Record all access and operation behaviors to data, including access time, visitor identity, operation type, etc., so as to facilitate tracing and investigation when security incidents occur.

[0162] (5) Data desensitization and anonymization

[0163] Data desensitization: Data that needs to be shared or made public is desensitized, such as through replacement, blurring or generalization, to protect personal privacy and sensitive information.

[0164] Anonymization processing: During the data analysis process, anonymization processing technologies such as differential privacy and k-anonymity are used to ensure that specific individuals cannot be identified from the data without affecting the data analysis results.

[0165] (6) Real-time security monitoring and response

[0166] Intrusion detection and prevention system: Deploy intrusion detection (IDS) and intrusion prevention (IPS) systems to monitor network traffic and abnormal behavior in real time, and promptly detect and prevent potential security threats.

[0167] Emergency response mechanism: Establish a comprehensive emergency response mechanism, including security incident reporting process, emergency plans and recovery plans, to ensure rapid response and restoration of normal system operation when a security incident occurs.

[0168] Based on the combined application of the above innovative measures, a simplified algorithm framework is constructed, which combines national secret algorithms (such as SM2, SM3, SM4, etc.) to ensure the data security of the intelligent management badge system. In this way, the service platform not only realizes the comprehensive protection of the intelligent management badge data, but also ensures the legal use and effective management of the data. These measures together constitute a multi-level, three-dimensional data security protection system, which provides a solid guarantee for the safe and stable operation of the intelligent management badge system.

[0169] In this embodiment, the specific algorithm is summarized as follows:

[0170] This algorithm example aims to demonstrate how to combine the national secret algorithm to achieve data security for the intelligent management badge system, including data encryption, hash verification, digital signature and key management. The specific steps are as follows:

[0171] Data encryption: Use the SM4 symmetric encryption algorithm to encrypt sensitive data.

[0172] Hash verification: Use the SM3 hash algorithm to perform hash calculation on the data to verify the integrity of the data.

[0173] Digital Signature: Use the SM2 elliptic curve digital signature algorithm to sign the hash value of the data to ensure the authenticity and integrity of the data.

[0174] Key management: Use a hardware security module (HSM) or key management service (KMS) to generate, store, and manage SM4 encryption keys and SM2 signing key pairs.

[0175] In this embodiment, the specific algorithm steps are as follows:

[0176] Key generation and management:

[0177] Use HSM or KMS to generate SM4 encryption key (Key_SM4) and SM2 signature key pair (PubKey_SM2, PrivKey_SM2).

[0178] Store Key_SM4 and PrivKey_SM2 securely in an HSM or KMS, and PubKey_SM2 is used to publicly verify the signature.

[0179] Data Encryption:

[0180] Before sending data, the smart management badge uses Key_SM4 to encrypt sensitive data (Data) and generate EncryptedData.

[0181] EncryptedData=SM4_Encrypt(Data,Key_SM4)

[0182] Hash check:

[0183] Calculate the SM3 hash value (Hash) for Data.

[0184] Hash=SM3_Hash(Data)

[0185] Digital Signature:

[0186] Use PrivKey_SM2 to digitally sign the Hash and generate a Signature.

[0187] Signature=SM2_Sign(Hash,PrivKey_SM2)

[0188] Data transmission:

[0189] Send the EncryptedData, Hash and Signature together to the service platform.

[0190] Data reception and verification:

[0191] After receiving the data, the service platform first uses PubKey_SM2 to verify the validity of the Signature.

[0192] SM2_Verify(Hash,Signature,PubKey_SM2)->True / False

[0193] If the signature verification passes, continue; otherwise, discard the data and report the security incident.

[0194] Recalculate the hash value of EncryptedData using the SM3 algorithm and compare it with the received Hash to verify the integrity of the data.

[0195] If the hash values ​​match, Key_SM4 is used to decrypt EncryptedData and restore the original data Data.

[0196] Data=SM4_Decrypt(EncryptedData,Key_SM4)

[0197] Data processing and storage:

[0198] Perform necessary processing on the decrypted Data, such as storing it in an encrypted database.

[0199] Sensitive data in the database is also stored using SM4 encryption to ensure that even if the database is illegally accessed, sensitive information cannot be directly read.

[0200] Secondly, the mobile terminal has a built-in mobile AAP, as shown in the following example: Figure 5 As shown in the figure, the main interface for users to interact with the smart management badge and the management system; users can view badge information, send instructions, receive notifications, etc. through the mobile APP. The mobile APP supports the NFC function and can wirelessly interact with the smart management badge to read, write and update data. At the same time, the mobile APP can also communicate with the service platform to upload the badge data to the service platform or receive data and instructions sent by the service platform.

[0201] In summary, the present invention provides an intelligent management badge, system and method for power supply guarantee personnel. Based on the mobile Internet of Things, the intelligent management badge has the advantages of small size, strong portability, low power consumption, and strong real-time data update, providing an efficient and convenient personnel management method for power supply guarantee work.

[0202] The above embodiment is only one of the implementation methods that can realize the technical solution of the present invention. The scope of protection claimed by the present invention is not limited only to this embodiment, but also includes changes, replacements and other implementation methods that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed by the present invention.
