It is directly displayed on item, when detected region somewhere portion temperature increases extremely, in automatic mode, system can be in conjunction with outside
Cigarette sense alarm signal issues pre-alarm or alarm signal by preset threshold value and arithmetic logic, can also directly command and go out
Fiery device action fire extinguishing.40 DEG C of a certain search coverage temperature can specifically be set as alarm first threshold point, 60 DEG C are Shi Wei
2 alarm threshold value points, 90 DEG C are third alarm threshold value point, cause to report by mistake to avoid light from opening caused transient temperature rise, together
When the region where lamps and lanterns is set as lamps and lanterns mode, i.e., temperature change threshold value be set as change dramatically in 30 milliseconds be more than 10 DEG C and
It in the case that the area and temperature are no more than 70 °, does not respond, is positioned as normally, not issuing any pre-alarm and alert data.When
When the detected a certain grid temperature anomaly in region is increased to 40 DEG C, if cigarette sense does not issue alarm signal, corresponding regional network
Lattice box color becomes pale red and is simultaneously emitted by the pre-alarm buzzer sound, points out observation, if external cigarette sense at this time
Interface also receives alarm signal simultaneously, and corresponding cigarette sense alarm indication item will flash on screen, and system will issue formal at this time
The fire alarm sound can interrupt alarm signal after observation video excludes emergency under artificial mode.If outside system
Portion's cigarette sense interface is to alarm signal, and regional temperature is within 40 DEG C, and corresponding cigarette sense alarm indication item will dodge on screen
Sparkling and issuing buzzer sound sound reminds monitoring personnel to pay attention to observing actual displayed temperature variations and real time video image, if
It was found that fire hazard can issue alarm signal manually, examination and repair system equipment can be notified when excluding fire hazard.When
When the detected a certain grid temperature anomaly in region is increased to 60 DEG C, corresponding area grid box color becomes red, even if
Cigarette sense does not issue alarm signal, and system will also start the formal fire alarm sound of external warning device sending, artificial mode at this time
It is lower to interrupt alarm signal after observation video excludes emergency, if external cigarette sense interface also receives alarm at this time
Signal, system will issue formal fire alarm under artificial mode, in automatic mode other than issuing formal fire alarm, system
Extinguishing action signal will be issued and start self-extinguishing program to fire extinguishing system.When detected region, a certain grid temperature anomaly is increased
When to 90 DEG C, even if cigarette sense does not issue alarm signal, system will also issue the formal fire alarm sound at this time, in automatic mode
Other than issuing formal fire alarm, system will issue extinguishing action signal and start self-extinguishing program to fire extinguishing system.
Monitoring personnel can check related real time data at any time under any circumstance, click grid or external fire alarm
It shows item, its historical data table or change curve can also be exported, in conjunction with real-time video situation, monitoring personnel can take sending
Alarm signal, notice such as check on the spot, take fire suppression measures at the movement, so not only can be to avoid having reported by mistake and failed to report but also can be in fire
The hidden danger of generation or early stage take fire suppression measures at the first time.
