[0096] The shared gas and liquefied gas password table system includes:

[0097] Smart gas meter module: responsible for gas metering and data collection, supporting multi-user sharing.

[0098] Authentication module: responsible for generating and managing user access passwords to ensure the legitimacy of user identities.

[0099] Data transmission module: responsible for transmitting the data collected by the smart gas meter to the background server, supporting multiple communication methods (such as WiFi, NBIoT, etc.).

[0100] Backend server module: responsible for data storage and processing, supporting functions such as user authentication, rights management and billing.

[0101] User interface module: provides a user operation interface, supporting users to view usage records, pay fees, and perform other operations.

[0102] Furthermore, the data processing flow of the shared gas and liquefied gas password table system is as follows:

[0103] Data collection: The smart gas meter module collects gas usage data in real time.

[0104] Data encryption: The collected data is encrypted and sent to the backend server through the data transmission module.

[0105] Data storage: The backend server module receives and stores encrypted data.

[0106] Data decryption and processing: The backend server decrypts and processes the received data to generate user usage records.

[0107] Billing and Notification: Billing is performed based on usage records and users are notified through the user interface module.

[0108] Furthermore, the user authentication and authority management process of the shared gas and liquefied gas password table system is as follows:

[0109] User registration: Users register through the user interface module, submit basic information and set an access password.

[0110] Password generation: The authentication module generates a unique access password for the user and binds it to the user information.

[0111] User login: The user logs in by entering the access password, and the authentication module verifies the legitimacy of the password.

[0112] Authority allocation: Assign corresponding gas usage authority based on user identity and authority level.

[0113] Usage monitoring: The smart gas meter module monitors user usage in real time based on permission settings.

[0114] Furthermore, advanced encryption algorithms and rights management algorithms are used to ensure data security and user privacy. These mainly include:

[0115] 1. Data encryption algorithm:

[0116] Using AES symmetric encryption algorithm, the encryption formula is as follows:

[0117] C=AES encrypt (K, P);

[0118] Among them, C is the encrypted ciphertext, K is the encryption key, and P is the plaintext data.

[0119] 2. Password generation algorithm:

[0120] Use the SHA256 hash algorithm to generate a unique access password. The formula is as follows:

[0121] Password = SHA256 (U info + Salt); where U info is the user's basic information, and Salt is a random salt value.

[0122] 3. Rights Management Algorithm (Continued)

[0123] In the role-based access control (RBAC) model, the specific implementation of permission allocation depends on the mapping relationship between roles and resources. The system defines multiple roles (for example: primary user, secondary user, temporary user, etc.), each with different permission levels. The permission allocation formula is as follows:

[0124]

[0125] Among them, AllowedRole(Resource) represents the set of roles that are allowed to access the resource. The system uses this algorithm to ensure that only users with appropriate permissions can access and use the corresponding gas resources.

[0126] Specifically, the smart gas meter module is used to collect the user's gas usage data in real time. It includes:

[0127] Data acquisition unit: measures gas usage through high-precision sensors and records usage time.

[0128] Gas meter data storage unit: Caches collected data locally to ensure data is not lost when communication is interrupted.

[0129] Data transmission unit: transmits the collected data to the background server through encrypted communication.

[0130] Furthermore, the authentication module is responsible for generating and managing user access passwords to ensure the legitimacy of user identities. This includes:

[0131] Password generation unit: Generates a unique access password based on user information and random salt value.

[0132] Password verification unit: Verifies whether the password entered by the user is legal.

[0133] Password reset unit: When a user forgets their password, they can reset it through a secure verification method;

[0134] Smart gas meter ID module (this module is integrated into the smart gas meter module) is used to identify the smart gas meter that the user will use;

[0135] User ID module (this module is integrated into the backend server) is used to store user identity information, match the gas meter requested by the user with the user identity and verify whether the smart gas meter is allowed to be used;

[0136] Specifically, the meter's identity information is collected through a mobile app and then transmitted to a server. The server then reviews the user information and transmits it to the smart meter. The smart meter then manages and controls the user's balance. The server can also send real-time instructions to the meter to manage user behavior. This includes meters with keyboard-based password input as well as those without keyboard-based input, such as the app's QR code scanning mode.

[0137] Furthermore, the data transmission module is responsible for transmitting the data collected by the smart gas meter to the background server, supporting multiple communication methods such as WiFi, NBIoT, etc. Including:

[0138] Data encryption unit: encrypts data before transmission to ensure data security.

[0139] Transport protocol unit: supports multiple transport protocols, such as MQTT, HTTP, etc.

[0140] Exception handling unit: performs exception handling and retransmission when communication is interrupted or data transmission fails.

[0141] Furthermore, the backend server module is responsible for data storage and processing, and supports functions such as user authentication, rights management, and billing. It includes:

[0142] Server data storage: stores the received encrypted data in the database.

[0143] Data decryption unit: decrypts and processes the received data.

[0144] User Management Unit: Manage user information and access rights.

[0145] Billing system unit: bills based on usage records and generates invoices.

[0146] Furthermore, the user interface module provides a user operation interface, supporting users to view usage records, pay fees, etc. It includes:

[0147] User login unit: The user logs in by entering the access password.

[0148] Usage record unit: Users can view their gas usage records.

[0149] Fee payment unit: Users can pay gas fees through online payment methods.

[0150] Notification system unit: The system notifies users of bills, abnormal situations and other information through messages.

[0151] In one specific embodiment, multiple users share a single gas meter in a shared housing scenario. Through the system of the present invention, each user can obtain a unique access password and use gas within their authorized range. The system then bills each user based on their usage and generates a bill at the end of the month to notify the user of the payment.

[0152] In a specific embodiment, the power supply is disposed inside or outside the housing.

[0153] In a specific embodiment, the authentication modes include manual password input; a mobile phone app scans the QR code on the meter to connect to the Bluetooth inside the meter; after the mobile phone app scans the QR code on the meter, the data is transmitted to the server, the server matches the user with the meter and sends the user's account balance to the meter, and after the user completes the use, the account balance, gas usage and other related information are sent to the server; there are three methods in total.

[0154] Specifically, the following is a detailed technical implementation plan for three authentication modes (manual password entry, mobile app code scanning - Bluetooth direct connection, and mobile app code scanning - cloud interaction) based on the intelligent management scenario of gas meters, covering the interaction process, data security, and exception handling mechanism:

[0155] 1. Manual password input authentication mode

[0156] The technical architecture includes:

[0157] Hardware layer: The gas meter has a built-in password input module with physical buttons (supports 0-9 numeric keys + confirm / cancel keys), the keyboard is IP67 waterproof and has an anti-static interference capability of 8kV;

[0158] Software layer:

[0159] Use AES-256 encryption algorithm to perform local hash operation on user passwords (SHA-3-512 + dynamic salt value);

[0160] Password error counter (5 consecutive errors trigger a 15-minute account freeze);

[0161] Encrypted storage of operation logs (recording timestamps, key sequences, and authentication results);

[0162] Implementation process:

[0163] User Action:

[0164] Wake up the meter (press the power button for 3 seconds) → Enter a 6-digit password (can be deleted with the * key) → Press the confirm button to submit

[0165] Local verification:

[0166] The meter-side MCU decrypts the pre-stored password library (stored in the TEE security zone)

[0167] If the comparison result matches, the solenoid valve is triggered to open (response time ≤ 200ms)

[0168] Exception handling:

[0169] When the password is incorrect, the buzzer will beep three times (frequency 1kHz)

[0170] During the account freeze period, the red "LOCK" icon will flash on the meter display.

[0171] Technical advantages include:

[0172] No network support required, suitable for basements with no signal or remote mountainous areas

[0173] Localized authentication reduces the cloud attack surface (avoiding the risk of man-in-the-middle hijacking)

[0174] 2. Mobile App Scan Code - Bluetooth Direct Connection Authentication Mode

[0175] Technical architecture:

[0176] Communication layer:

[0177] The meter integrates a BLE 5.3 dual-mode chip (supports broadcast mode + GATT protocol)

[0178] The mobile app scans the meter's UUID (0x180A Device Information Service) through the Android Beacon library / iOS CoreLocation framework

[0179] Security layer:

[0180] Bluetooth key negotiation based on elliptic curve cryptography (ECC-P256)

[0181] Dynamic token mechanism (authentication token is refreshed every 30 seconds, generated based on HMAC-SHA256)

[0182] Implementation process:

[0183] User Action:

[0184] Open the gas company app → select "Scan code to bind meter" → scan the dynamic QR code on the meter (including meter ID, device public key, and timestamp)

[0185] Bluetooth pairing:

[0186] The mobile app parses the QR code to obtain the meter's MAC address → initiates a Bluetooth connection request (Service UUID: 0xFFE0)

[0187] The meter displays a 6-digit random verification code, which the user needs to enter on the App to complete two-way authentication.

[0188] Data interaction:

[0189] After authentication is passed, the App writes the prepaid amount to the meter (using Protobuf binary encoding to compress the transmission amount)

[0190] The table returns the encrypted key version number, initial remaining amount, and last synchronization timestamp.

[0191] Technical advantages:

[0192] Strong anti-interference performance for near-field communication (Bluetooth penetration through brick walls attenuation ≤ 15dBm)

[0193] Support offline recharge (data is temporarily stored locally and automatically re-transmitted after network recovery)

[0194] 3. Mobile App Scan Code - Cloud Interactive Authentication Mode

[0195] Technical architecture:

[0196] System layer:

[0197] Table end: MQTT over TLS1.3 communication module (supports breakpoint resuming and heartbeat packet keepalive)

[0198] Cloud: Microservice architecture (including user center, device management, billing engine, and risk control module)

[0199] Security layer:

[0200] Three-party encryption system:

[0201] Table-side private key (ECC-SECP256R1)

[0202] Platform CA certificate (RSA-4096 signature)

[0203] National secret SM4 algorithm (used for transport layer data encryption)

[0204] Implementation process:

[0205] User Action:

[0206] Scan the QR code on the meter → App parses and obtains meter SN, gas company ID, and signature data

[0207] Cloud interaction:

[0208] Step 1: The App initiates an authentication request to the user center (with the meter SN, user token, and geographic location)

[0209] Step 2: Verify the validity of the token in the user center → Call the device management service to query the meter status

[0210] Step 3: The billing engine calculates the account balance (taking into account tiered gas prices and discounts) → generates an operation instruction package (including instruction ID, action type, and encryption parameters)

[0211] Table-side execution:

[0212] The meter verifies the digital signature of the instruction package → decrypts the operation parameters (the key rotation cycle is 7 days)

[0213] Execute valve opening / recharging operations and update local storage simultaneously (EEPROM partition erase and write life ≥ 100,000 times)

[0214] Results feedback:

[0215] The meter encrypts and transmits the operation results (success / failure code, execution time, remaining amount) back to the cloud. The cloud pushes a notification to the user's app (including electronic voucher and usage analysis chart).

[0216] Technical advantages include:

[0217] Support multi-dimensional risk control (abnormal large-amount recharge triggers facial recognition verification)

[0218] Remote firmware upgrade (FOTA differential package ≤ 50KB, network disconnection success rate ≥ 99.2%)

[0219] 4. Security Enhancement Mechanism

[0220] Anti-replay attack:

[0221] All communication packets carry a timestamp (error tolerance ±30 seconds) + a random number Nonce (128 bits)

[0222] The cloud automatically discards duplicate instruction packets (based on Redis Bloom filter);

[0223] Key rotation strategy:

[0224] The meter key is automatically updated at 3:00 am every day (based on a hardware true random number generator);

[0225] When cloud keys are leaked, batch revocation is supported (through the blockchain evidence key version chain);

[0226] Abnormal behavior detection:

[0227] Establish a user behavior baseline (e.g., average daily gas usage, recharge frequency);

[0228] Trigger the rule engine (for example, if the recharge exceeds 3 times in a single day and the amount is greater than 500 yuan, facial verification is mandatory)

[0229] 5. Compliance Design

[0230] Data Privacy:

[0231] Table-side storage data encryption (compliant with GDPR Article 32 "Confidentiality, Integrity, and Availability" requirements)

[0232] Desensitization of user geographic location information (retaining only district and county-level accuracy);

[0233] Metrology regulations:

[0234] Cloud data is used as a reference value, and metering disputes are subject to local records at the meter end.

[0235] This solution uses a three-level certification system of local-edge-cloud, taking into account security, ease of use and compliance, and can support gas companies in achieving the intelligent transformation goals of full-scene coverage, full-link control, and full life cycle management.

[0236] In a specific embodiment, in a temporary rental scenario, the landlord can use the system to generate a temporary access password for the tenant and set usage permissions and time limits. The tenant can use gas during the rental period, and the system will bill based on usage. After the rental period ends, the system automatically revokes the tenant's access rights.
