2results about How to "Improve accounting efficiency" patented technology

This invention discloses a privacy-preserving method and apparatus for revenue sharing based on a Trusted Execution Environment (TEE), belonging to the field of privacy computing technology. The method includes: collecting traffic and revenue settlement data from multiple business systems, encrypting the data after standardized preprocessing, and transmitting it through a secure channel to a secure enclave within a Trusted Execution Environment (TEE); loading revenue sharing rules and generating a smart contract within the enclave, determining the accounting logic and constraints, performing isolated calculations on the encrypted data, obtaining the revenue sharing amount for each partner, and completing consistency verification; extracting key information to generate data fingerprints for on-chain storage, distributing the encrypted calculation results to authorized nodes, and completing closed-loop settlement. This invention utilizes a TEE to achieve encrypted closed-loop calculation, solving the privacy and trust issues in multi-party revenue accounting. Combining smart contracts and blockchain storage improves the efficiency, accuracy, and traceability of calculating billions of traffic data points.

This invention relates to the field of petrochemical safety production management technology, specifically to an intelligent on-site safety management platform for petrochemical plants. The platform comprises a perception layer, a transmission layer, a data layer, an application layer, and a display layer. These layers work together to achieve full-process coverage of on-site safety management in petrochemical plants. The perception layer is equipped with positioning terminals, health monitoring equipment, behavior recognition equipment, and environmental monitoring equipment to collect personnel location, health data, work behavior, and environmental parameters. The transmission layer utilizes a 5G private network, a WIFI local area network, and a ZigBeePlus wireless communication module to achieve high-speed and stable data transmission between the perception layer and the data layer. This invention, through ZigBeePlus three-dimensional positioning technology, achieves personnel positioning accuracy down to the meter level, accurately pinpointing the specific location of personnel in plant areas and confined spaces. Vital signs are linked in real-time with location data; when personnel exhibit health abnormalities or are in dangerous areas, the system can quickly trigger an early warning and lock their location, reducing rescue response time by more than 50% and significantly reducing the risk of personnel injury or death.
