This utility model discloses a data processing board for trackside equipment, belonging to the technical field of subway trackside equipment. It includes a data processing module, a soft-start output module, a power-down voltage monitoring module, an RTC real-time clock module with a first energy storage capacitor, a power supply module with a second energy storage capacitor, and a data interface module. The data processing module is electrically connected to the other modules. The power supply module provides the operating voltage to the board, and its second energy storage capacitor temporarily supplies power to the data processing module during brief external power outages to record the voltage status data at the moment of power failure. The first energy storage capacitor of the RTC real-time clock module maintains clock operation for a preset duration after power failure. This utility model solves the problems of easy data loss and clock failure during power failures in traditional boards. It features high structural integration, stable operation, and accurate recording of power-down fault conditions, meeting the data continuity requirements of subway trackside equipment.

The present invention discloses an Internet of Things information management method and system based on blockchain, the method includes: identity verification and business execution process in the Internet of Things business process, including: interacting the packaged Internet of Things control information with the identity review contract on the chain, and the smart contract is used to record the packaged Internet of Things control information; the auditor extracts the information package submitted by the business initiator from the identity review contract, completes the verification of the identity of the business initiator, and manually reviews the rationality of the operation; the auditor calls the identity review contract to complete the call of the business processing contract; the Internet of Things logistics information authentication code generation and chain process includes: splicing the Internet of Things information DNA string; using the private key to generate a digital signature; the node miner packages the transaction into the block; the network node confirms the transaction in the block. The present invention can improve the efficiency and reliability of logistics management.

The invention provides an interconnection device and method of an fnirs host, the host, an interconnection assembly of the host, an upper computer and an imaging system. The interconnection device comprises a first interconnection interface and at least one second interconnection interface, the first interconnection interface and the second interconnection interface have different dominant physical attributes, an fnIRs host plugged by the first interconnection interface is used as a master device, and an fnIRs host plugged by the second interconnection interface is used as a slave device; the main processor is configured to sample the received marking trigger signal based on a second sampling rate greater than the first sampling rate of the fnrs host, and send marking time sequence data obtained after sampling to the outside; and the processing circuit is configured to receive the acquisition synchronization time sequence signal sent by the master device through the first interconnection interface, and send the acquisition synchronization time sequence signal to each slave device through the second interconnection interface. According to the scheme, interconnection of a plurality of low-channel fnirs hosts can be conveniently realized, and a near-infrared equipment combination scheme which is compact in structure, concise in connection line and adaptive to various modal collaborative combination scenes is constructed.

The invention discloses a high-speed rail data storage and traceability method based on alliance chain and attribute-based encryption, and belongs to the technical field of traffic flow traceability analysis, and the method comprises the following steps: S1, employing a distributed key generation and management scheme based on Shamir threshold sharing, and generating and storing a key for a user; s2, adopting a data encryption scheme based on attribute-based encryption to encrypt data which is uploaded by a user and needs to be encrypted; and S3, supervising a data uploading and sharing process by adopting a traceability process supervision scheme to form a high-speed rail data storage and sharing solution based on the block chain. Compared with a traditional high-speed rail data management mode which usually depends on a centralized storage and access control scheme, the method has the advantages that the security and the restorability of a private key are remarkably improved, the flexibility and the privacy of data sharing are greatly enhanced, the system performance is optimized, and the behavior supervision transparency is improved.

The invention relates to the technical field of automobile fault data processing, in particular to an automobile fault and maintenance information management platform based on data processing, which is provided with a plurality of information collection terminals, a cloud server and a plurality of index terminals. The response category of the fault database is judged through a preprocessing unit in the cloud server, the mode of updating the fault database and the position database is selected through an information updating unit in the cloud server, an information index database is loaded through a plurality of index terminals, a target index terminal is selected according to the loading rate, and then the fault database and the position database are updated. According to the invention, analysis is carried out according to the specific data condition of the vehicle fault, the data indexing quantity for indexing the platform is adaptively adjusted, and the operation efficiency of the vehicle fault maintenance information management platform is improved.
