The invention relates to the field of blend oil production, in particular to a blend oil production process DCS (Distributed Control System) decentralized control system, which comprises a blend oil production process module used for executing production and processing of blend oil; the DCS control system module is used for performing decentralized control on each blend oil production process module; the DCS control system module comprises a central control module and a plurality of sub-control modules, the sub-control modules are used for independently controlling all the blend oil production process modules, and the central control module directly completes configuration with all the sub-control modules based on stored structured HAZOP deviation analysis records and LOPA grading results. The DCS control system adopts a distributed structure, a plurality of system components are distributed on an open redundant communication network, and the system components are provided with independent function processors, have maintenance and self-diagnosis functions, and can perform early warning to ensure the safe work of the blend oil production process.

This invention provides an intelligent fire extinguishing system for a shaft boring machine (TBM), comprising a fire detection and sensing unit, a TBM equipment status sensing unit, an intelligent fire control center, a fire extinguishing execution unit, a remote data transmission unit, a lighting and alarm unit, and a power management unit. The fire detection and sensing unit and the TBM equipment status sensing unit are electrically connected to the remote data transmission unit, which is electrically connected to the intelligent fire control center. The intelligent fire control center is electrically connected to the fire extinguishing execution unit and the lighting and alarm unit. The power management unit supplies power to the entire system. This invention aims to solve the problems of slow response speed, poor fire extinguishing effect, lack of intelligence, and insufficient safety in existing shaft boring machine fire protection systems, in order to meet the safety requirements of pumped storage power station tunnel projects.
