Exploration on Communication Technologies for Automatic Fire Alarm Systems in the Petrochemical Industry

Currently, the automatic fire alarm systems installed and used in the petrochemical industry adopt the same bus communication technology as those in civil buildings. However, due to the higher requirements for communication reliability and more severe electromagnetic interference in petrochemical sites, problems such as data transmission errors, communication interruptions, false alarms, and system crashes frequently occur during bus communication. This paper analyzes the communication problems existing in the automatic fire alarm systems applied in the petrochemical industry and proposes solutions from a standardization perspective.
