Description
Technical field
The invention belongs to technical field of fire safety, more particularly to a kind of fire fighting monitoring early warning system suitable for laboratory
System.
Background technology
Laboratory can occur security incident often, all be all the time Key Unit of Fire Safety, the generation of security incident
3 reasons nothing more than：The unsafe condition of thing, Unsafe behavior and management defect, just for 3 points of the above：Laboratory
Store a large amount of inflammable and explosive hazardous materials and all kinds of high-power electrical equipments and instrument；Lab assistant mobility is big, behaviour
Make lack of standardization, awareness of safety degree differs；Most of the time is experimenter's autonomic nerve way, and experiment management personnel can not possibly the moment
Supervision, notably some experimental periods are more long, there is unmanned experiment, situations such as night is unattended.For laboratory problem above,
It is necessary to design a kind of fire fighting monitoring early warning system suitable for laboratory, in advance strangles in cradle potential safety hazard,
Prevent security incident or accident to find to cause accident to spread not in time, cause bigger casualties and property loss
Situation.
The content of the invention：

Controller is also connected with non fire fighting power supply break-make relay control coil wire.
Manual alarm switch is connected with controller wire.
Reset switch is connected with controller wire.
On-off transducer is arranged on various experiment electrical equipments, opening or stopping state and carry out to various experiment electrical equipments
Monitoring.
Display panel is arranged on laboratory outdoors；Display panel shows the monitoring number of each sensor in time and laboratory in real time
According to.
It also includes fire-fighting power supply, and the fire-fighting power supply provides power supply for monitoring early-warning system.
Beneficial effects of the present invention：
The present invention devises a kind of fire fighting monitoring early warning system in laboratory, and it mainly includes fire-fighting power supply, controller, all kinds of prisons
Survey sensor, display panel, information generator, audible-visual annunciator, non fire fighting power supply break-make relay, smoke exhaust fire damper and report manually
Alarm device etc., by each electrical equipment start-stop state in real-time monitoring laboratory, smog, temperature, pernicious gas situation of change, together
When be displayed on outdoor display disk, facilitate teaching building administrative staff to patrol building；Experiment is sent by the settable timing of information generator
The data message of each sensor of room facilitates laboratory room managing personnel remotely to monitor to predetermined telephone；Whole system is realized and carried
The effect of preceding early warning, information generator, audible-visual annunciator, non fire fighting power supply circuit breaker, smoke exhaust fire damper are realized according to controller
Automatic, or manual alarm, before accident occurs or expands warning, every cigarette back-fire relief, cut off the electricity supply, alarm, allow
Experiment management personnel and fire fighter take corresponding measure the very first time, prevent from causing bigger causality loss.The invention is solved
Existing laboratory is unable to the problems such as monitor in real time, alarm time delay, accident be uncontrollable, is the management and monitoring in laboratory are taken
It is convenient, there is provided safety experiment environment higher.
Brief description of the drawings：
Fig. 1 is schematic structural view of the invention.
Specific embodiment：
A kind of laboratory fire fighting monitoring early warning system（See Fig. 1）, it includes controller, and controller is controlled using single-chip microcomputer or PLC
Device；On-off transducer, Smoke Sensor, temperature sensor and gas sensor are connected with the input wire of controller；Control
The output end of device is connected with display panel, information generator, acoustic-optic alarm wire.
Information generator sends to presetting number of cell phone the monitor state information in laboratory in real time, facilitates laboratory to manage
Reason personnel know correlation circumstance in laboratory in real time.
Acoustic-optic alarm can remind the personnel around laboratory to take emergency measures.
The digital output end of controller is also connected with the control coil wire of smoke exhaust fire damper；Smoke evacuation system is controlled
System, realizes automatic smoke exhausting control.
The digital output end of controller is also connected with non fire fighting power supply break-make relay control coil wire；In fire hair
When raw, the control coil of the exportable signal control relay of controller cuts off whole power supply；Control accident spreads.
Manual alarm switch is connected with controller input wire;Switched by setting manual alarm, in case of emergency,
Manually alarm switch can directly be alarmed.
Reset switch is connected with controller input wire；After Failure elimination, resetted by reset switch.
On-off transducer is arranged on various experiment electrical equipments, opening or stopping state and carry out to various experiment electrical equipments
Monitoring.
Display panel is arranged on laboratory outdoors；Display panel shows the monitoring number of each sensor in time and laboratory in real time
According to.
It also includes fire-fighting power supply, and the fire-fighting power supply provides power supply for monitoring early-warning system.
Laboratory safety state is divided into three-level by preset data interval of the present invention：Normally（Ⅰ）, it is slight（Ⅱ）, it is serious（Ⅲ）,
By the Monitoring Data of each sensor, according to different safe coefficients, controller sends different action commands to controller.
Controller is connected with acoustic-optic alarm, and acoustic-optic alarm is also disposed at laboratory outdoors, works as Laboratory Monitoring
Safe condition is slight（Ⅱ）Or it is serious（Ⅲ）When, audible-visual annunciator will send sound and light signal, remind the personnel around laboratory
Take emergency measures.
Controller is connected with the break-make relay of non fire fighting power supply, when Laboratory Monitoring safe condition is serious（Ⅲ）When,
The power supply of all electrical equipments of non fire fighting power supply circuit breaker Automatic Start Interrupt, control accident spreads.
Smoke exhaust fire damper is connected with controller, and smoke exhaust fire damper can be automatically controlled by controller, also manually controllable, and
It is installed on the pipeline of mechanical smoke extraction system, usually in normally off and meets inleakage requirement；When laboratory smokescope and
When concentration of toxic gases reaches preset value, control device will automatically turn on smoke exhaust fire damper, or need manual unlocking according to experiment
And closing, play smoke evacuation；Temperature sensor is provided with smoke discharging pipe, is closed when flue-gas temperature reaches 280 DEG C, and certain
Time interior energy meets leakage smoke and fire integrity demands, serves every cigarette back-fire relief.
