Description

Fire fighting system self-checking system based on Internet of things and use method thereof

Technical Field

The invention relates to the field of fire fighting, in particular to a fire fighting system self-checking system based on the Internet of things and a using method thereof.

Background

Fire-fighting linkage control means that after a fire detector detects a fire signal, a relevant air conditioner in an alarm area can be automatically cut off, a fire valve on a pipeline is closed, a relevant air exchange fan is stopped, a smoke exhaust valve of the relevant pipeline is opened, an electric fire door and a fire-proof rolling door at relevant positions are automatically closed, a non-fire-fighting power supply is sequentially cut off, an accident lighting and evacuation marker lamp is switched on, all elevators except a fire elevator are shut down, and a fire extinguishing system is immediately started through a controller of a control center to automatically extinguish fire. The linkage can be generally divided into two forms of centralized control, decentralized control and centralized control, and the control modes include linkage (automatic) control, non-linkage (manual) control and linkage and non-linkage combination.

A fire hydrant, called fire hydrant formally, is a fixed fire-fighting equipment, and mainly has the functions of controlling combustible substances, isolating combustion-supporting substances and eliminating ignition sources. It is divided into indoor fire hydrant and outdoor fire hydrant. The fire extinguishing system comprises an outdoor fire hydrant system, an indoor fire hydrant system and a fire extinguisher system, and some fire extinguishing systems also comprise an automatic spraying system, a water cannon system, a gas fire extinguishing system, a fire detection system, a water mist system and the like. The fire hydrant is mainly used for the fire fighting truck to take water from a municipal water supply network or an outdoor fire fighting water supply network to put out a fire, and can also be directly connected with a water hose and a water gun to discharge water to put out a fire. Therefore, indoor and outdoor fire hydrant systems are also one of the important fire fighting devices for fighting fires.

The centralized control system is a system which carries out centralized control, display and unified management on all fire-fighting facilities in the system through a fire-fighting control room. The system is suitable for a system with a bus system, a digital control implementation mode and a communication mode, and is particularly suitable for a building automation management system controlled by a computer; when the number of control points is small and the control points are scattered, a multi-wire system is also commonly used. When the number of control points is extremely large and dispersed, in order to make the control system simple and reduce the position display of control signals and the number of control lines, a system combining dispersion and concentration can be adopted, and usually a fire pump, a blower, a smoke prevention and exhaust fan, a part of fire-proof rolling doors, an automatic fire extinguishing control device and the like are subjected to centralized control and unified management in a fire control room; the field decentralized control can be adopted for large and decentralized control systems such as smoke prevention and exhaust fans, fire door releasers and the like. It should be emphasized that regardless of the control system, the operation signal of the controlled object actuator is sent to the fire control room for centralized display. Controlled objects (such as elevators, non-fire-fighting power supplies and the like) which are easy to cause disorder and bring serious consequences in high-rise buildings are managed in a centralized way by a fire control room.

Generally speaking, because the fire control shower nozzle exposes outside, when not using for a long time, the condition that takes place this dust of delivery port and block up easily takes place, when the condition of a fire appears, influences the spray regime that conflagration water goes out water, is unfavorable for the efficiency and the effect of fire control, and causes the condition of a fire and can't in time cover out, has great potential safety hazard.
