Staff in the tunnel and outside the tunnel hears the cable tunnel that speeds away behind the chimes of doom, and relevant fire fighter will arrive in condition of a fire generation scene rapidly and take the measure of putting out a fire accordingly.
When fire alarm, described fire-fighting hub-interface unit sends to the fire-fighting center with the fire alarm early warning signal through network.If the condition of a fire not quite disposes very soon, relevant treatment personnel see fire district safety just press the reset key in the display apparatus without any danger, remove and report to the police.At this moment, the circuit of electromagnetic lock is connected, and fireproof door opens wide, and all alarms stop to report to the police, and extinguishing device also stops fire extinguishing, and all reply normal condition.
Above-mentioned operational example can demonstrate in the centralized displaying on ground simultaneously as pressing reset key.Centralized displaying alarm in the control room, ground all demonstrates the feedback information of CPU, so that inform the situation that staff's condition of a fire on ground is handled.
Here explanation a bit, if master controller and alarm, when the circuit of fireproof door control and extinguishing device breaks down, manual operation in the flow chart of steps of the method for fire protection of cable tunnel as shown in Figure 2, personnel in the tunnel find can also take manually to control alarm equipment alarm after the condition of a fire, control manually that fireproof door is closed and manual control fire extinguishing lamp fire prevention measure.
Embodiment two
If the condition of a fire appears in No. two fire districts and No. five fire districts, above operating process most of existing with, an existing simple declaration is difference once, identical operations is not just repeating.
For example smoke sensing T2y at first sends alarm signal to master controller A1, master controller T5w sends alarm signal to master controller A2 then, according to going out to judge that the generation area of the condition of a fire is second fire district and the 5th fire district, the fireproof door of being controlled by A1 is 01 respectively for master controller A1 and A2
#, 02
#, 03
#, the fireproof door of A2 control is 03
#, 04
#, 05
#, 06
#, because fireproof door 03
#Be the public fireproof door that A1 and A2 control simultaneously, so at A1 control fireproof door 03
#After closing, A2 is not just controlling it.The situation that in the centralized displaying warning device, shows the fireproofing installation in two fire districts.Other operation is identical with embodiment one, no longer repeats here.
