An asynchronous and concurrent transaction processing method with high-performance oriented to a permissioned blockchain belongs to the field of blockchain technologies. The method designs two processing schemes for abort transactions, namely, additional submission of unnecessary abort transactions that are serializable and delayed centralized processing of long-conflict-chain transaction aggregation. In order to avoid the instability of system transaction processing performance caused by single point failure, the method designs a multi-node round robin consensus strategy. In addition, an inter-node auxiliary concurrency acceleration scheme is designed, which can improve the transaction performance of the whole of the system only by upgrading some of node devices in the system.

Disclosed is a method for identifying and parsing an industrial control protocol based on an industrial gateway. The industrial gateway captures, through a serial port and a network port, messages sent from a host computer and a lower computer to the industrial gateway, extracts features representing different protocol types and protocol fields from the messages, and identifies and parses the messages based on protocol character features.

Disclosed are a drinking under influence (DUI) detection system and a DUI detection method based on an MQ3 sensor and an ultra wide band (UWB) radar. The system includes an alcohol detection module, a respiratory detection module, a signal matching module and a drunk driving alarm module, and each module cooperates to complete a detection. The MQ3 sensor-based alcohol detection module is used for alcohol signal capture, alcohol sequence processing and DUI threshold detection; the UWB radar-based respiratory detection module is used for respiratory signal capture, respiratory signal processing and passenger separation and positioning; the signal matching module is used for periodic signal alignment, sequence feature matching and drinker identity confirmation; and the DUI alarm module is used for a system alarm prompt, a data visualization interface and a DUI information uploading.
