Supplementary explanation.
When classroom catches fire, the smoke detector 3 detects that smog, the smoke detector 3 are controlled by the PLC
Device 2 sends alarm signal to the monitoring computer 1, and concurrently the alarm signal triggers the light coupling relay 5 and is connected, and makes institute
4 work once electrified of camera is stated, by the PLC controller 2, the camera 4 and the monitoring computer 1 form data transmission and close
System, in a few minutes clock time in incipient fire stage, the camera 4 can largely use, valuable using this
At initial stage a few minutes best rescue time, in actually rescuing, one side rescue personnel oneself fast searching rescue, on the other hand,
Monitoring work personnel check that the shooting image of the camera 4, monitoring work personnel can be with rescues using the monitoring computer 1
Personnel utilize communication device real-time contacts, to instruct rescue personnel to go to the classroom of someone to rescue at the first time, are searched as auxiliary
Means realization is rescued quick and precisely to rescue.
Under normal conditions, because the smoke detector 3 will not trigger alarm, the light coupling relay 5 will not be triggered conducting,
What is formed again by the light coupling relay 5 and the camera 4 is series circuit, which is hardware connection, and is tactile
Hair control, thus the camera 4 will not obtain electric under normality, the monitoring computer 1 can not control the camera 4
System, thus the individual privacy that classroom middle school student live can not only have been ensured by the utility model, but also can realize in incipient fire
Stage, it is contemplated that student faces the agenda ability of fire disaster escaping, is realized using camera 4 as auxiliary search and rescue means quick
Accurate rescue.
It should be pointed out that the utility model in, the camera 4 it is electric after pass through the PLC controller 2 and the prison
The relationship that computer 1 forms data transmission is controlled, the software section being related to, such as transport protocol, what is be all made of is prior art camera 4
