Urban switching station fire protection and fire extinguishment system

Abstract

The invention provides an urban switching station fire protection and fire extinguishment system comprising a fire automatic alarming subsystem and an automatic fire extinguishment subsystem. The fireautomatic alarming subsystem and the automatic fire extinguishment subsystem are both connected with a fire protection control main machine. The fire automatic alarming subsystem comprises a fire alarming controller. The fire alarming controller is connected with fire detectors, an input module, an output module, a hand-operated start button, a sound-light alarm and the fire protection control main machine. The fire detectors include the first suction type detectors and the second suction type detectors. Each first suction type detector and each second suction type detector are each connectedwith the fire alarming controller through two buses. The second suction type detectors cooperate with a machine cabinet, an air return pipeline and an air return grating through sampling pipelines correspondingly. According to the urban switching station fire protection and fire extinguishment system, by means of the suction type smoke detectors, fire can be detected very early, measures can be taken in time, and safe operation of a switching station is ensured; and secondly, unnecessary start of the fire extinguishment subsystem is reduced, and maintenance workloads are reduced.

Description

technical field [0001] The invention relates to the technical field of fire alarms for urban opening and closing stations, in particular to a fire extinguishing system for urban opening and closing stations. Background technique [0002] Compared with the general meaning of fire prevention in urban switching stations, the computer room has its own characteristics, which are mainly reflected in the following points: 1. There are many kinds of flammable materials, and there are a large number of complete functions and expensive instruments and equipment in the modern electronic communication computer room. Wires and cables and various storage media, among them, the components inside the equipment and the cable insulation jacket are mostly made of flammable materials such as carbolic acid fiber and polyvinyl chloride, which are extremely easy to burn and cause disastrous consequences. 2. There are many fire induction mechanisms, and the resulting hazards are also diverse. Fires...

Problems solved by technology

[0004] In view of the fact that the traditional fire alarm equipment in the opening and closing station is difficult to detect the early fire, and the traditional point fire detectors are passive detection, the installation position is at the top, the detection range and detection accuracy are difficult to meet the fire prevention in the existing opening and closing station The technical problem of demand, the present invention proposes a kind of city switch station fire extinguishing system
