Multi-criterion synergistic fire detection and alarm system for urban underground comprehensive pipe gallery electric power cabin

Abstract

The invention relates to a multi-criterion synergistic fire detection alarm system for an urban underground comprehensive pipe gallery electric power cabin, which is characterized by comprising an optical fiber type temperature sensing detector, a combined fire sensor, a suction type combustible gas detector, a comprehensive data analysis host and an alarm device, and is characterized in that a temperature sensing optical fiber of the optical fiber type temperature sensing detector is laid on a pipe gallery cable; and the combined fire sensor and the suction type combustible gas detector are installed on the top of the pipe gallery, the optical fiber type thermal detector host, the combined fire sensor and the suction type combustible gas detector are respectively connected with the comprehensive data analysis host, and the comprehensive data analysis host is connected with the alarm device. The system has the advantages that the optical fiber type temperature sensing detector, the air suction type smoke detector and the suction type combustible gas detector are synergistically designed and combined according to composite and multi-criterion concepts, the defects of fire detection and prevention of a comprehensive pipe gallery power cabin in China can be effectively overcome, and the basic requirements of an underground comprehensive pipe gallery complex environment are met.

Description

technical field

[0001] The invention relates to a multi-criteria synergistic fire detection and alarm system for an electric cabin of an urban underground comprehensive utility gallery, which belongs to the technical field of fire safety technology. Background technique

[0002] As an important form of cable channels such as communication, high-voltage power and intelligent weak current system signal transmission, the power cabin of the comprehensive pipe gallery belongs to the carrier of auxiliary facilities along the line laying path. Insufficient inspection methods and low operating status control have become important constraints for the improvement of the intrinsic safety of urban cable networks. The power cabin of the integrated pipe gallery is different from ordinary cable channels. The cabin body is buried deeper and the operating environment is more complicated. Problems such as fire, external damage, water accumulation, settlement, air turbidity, and lighting diffi...
