For achieving the above object, the technical solution used in the present invention is: fire-fighting automatic alarm control system for subway, it is characterized in that: comprise the multiple cameras for gathering image in subway station, for gathering multiple smoke transducers of smoke signal in subway station, the multiple local alarm controllers that join with camera and smoke transducer and the concentrated alarm controller joining with multiple local alarm controllers, also be included as the power module of native system power unit power supply, the output terminal of described concentrated alarm controller is connected to the voice cue module for reminding passenger to evacuate, for sending the audible-visual annunciator of warning to passenger, for opening the solenoid valve one of automatic shower nozzle fire extinguishing, for opening the solenoid valve two of hose saddle water spray, thereby thereby for making relay one that the power-off of down escalator drive motor prevents that passenger from entering the station and for making fire resisting shutter drive motor obtain the relay two of electric unlatching fire resisting shutter, described solenoid valve one is arranged in the water supply line of automatic shower nozzle, described solenoid valve two is arranged in the water supply line of hose saddle, described relay one is serially connected in the current supply circuit of down escalator drive motor, described relay two is serially connected in the current supply circuit of fire resisting shutter drive motor, the output terminal of described concentrated alarm controller is also connected to display.
Fire-fighting automatic alarm control system for above-mentioned subway, is characterized in that: the input end of described concentrated alarm controller is connected to and is used to system that the clock circuit of time reference is provided and for making the reset circuit of system reset.
The present invention compared with prior art has the following advantages:
1, of the present invention simple in structure, rationally novel in design, be easy to install.
2, when the present invention uses, by smoke transducer, smog is gathered, and in the time finding smokescope, report to the police by audible-visual annunciator, carry out voice broadcast by voice cue module, in the time that smokescope reaches setting concentration, thereby control solenoid valve one unlatching automatic shower nozzle and start fire extinguishing, control solenoid valve two is opened hose saddle and is put out a fire, and by pilot relay one, thereby make the power-off of down escalator drive motor prevent that passenger from entering the station, in order to prevent fire spreading, can pass through pilot relay two, make the work of fire resisting shutter drive motor, pull on fire resisting shutter, its effect is rapid, can effectively control the intensity of a fire.
4, of the present invention to realize cost low, and result of use is good, is convenient to promote the use of.
In sum, the present invention is simple in structure, and rationally novel in design, functional reliability is high, long service life, and fast response time, can find the condition of a fire and report to the police and corresponding counter-measure, its result of use is good in time.
Below by drawings and Examples, technical scheme of the present invention is described in further detail.
