Embodiment one
Now the condition of a fire occurring with an area of fire protection is example, and the working condition to fire prevention system of the present invention is explained as follows in detail.
Because scattering and disappearing of the heat of buried cable tunnel inner cable own makes that the temperature in the whole tunnel is higher, typical temperature is the normal temperature value at 58 ℃.When the temperature in area of fire protection was higher than 58 ℃, temperature inductor T1w sent an early warning signal to master controller A1.Here, if the smokescope that smoke sensing device T1y senses during greater than normal smokescope, it also can send an alarm signal to master controller A1.One judging unit of described master controller judges that according to the alarm signal that receives and initialization in advance the information in the described controller of being stored in the area of fire protection that the condition of a fire appears in place that this signal sends is a fire district.This initialization canned data is all fire equipments such as the sensor in the area of fire protection of controlling about described controller, fireproof door, and the table of comparisons of information such as alarm and area of fire protection, this table has reflected the fire equipment that is had in each fire district in detail.Then, the processing unit of described master controller is at once to an area of fire protection that the condition of a fire the occurs control operation of preventing fires, and the signal of the condition of a fire of simultaneously a described fire district being in danger sends to the master controller A2 that links to each other.
Its concrete fire prevention operation is as follows, and described processing unit one learns that the place that the condition of a fire occurs is behind fire district, just according to rapidly to the fireproof door 01 of an area of fire protection
#The gate light alarm W61 and the voice guard W62 of top send early warning signal, after described gate light alarm is received described early warning signal, the gate light flicker is reported to the police, after described voice guard is received described early warning signal, the prompt tone that sends ear-piercing alarm sound immediately or instruct people to evacuate, " for example a fire district is reported to the police, and please speed away ".And gate light alarm W61 and voice guard W62 are after starting warning, to a feedback signal is issued described processing unit.
The processing unit of described master controller A1 is after learning that the place that the condition of a fire occurs is fire district, simultaneously send control signal to fireproof door action actuating mechanism C1, described fireproof door action actuating mechanism according to received control signal after, at once to fireproof door 01
#Carry out closed procedure.Here, the fireproof door action actuating mechanism is an electromagnetic lock and door closer, described processing unit cuts off the circuit of electromagnetic lock, make it lose magnetism, because fireproof door is not when being cut off circuit, under the magnetic action of electromagnetic lock, be in opening-wide state always, after the magnetic action that loses electromagnetic lock, under the pulling force effect of the door closer on the fireproof door, make the fireproof door closure.
The processing unit one of described master controller A1 receives the fire district signal of definite appearance condition of a fire, it sends control signal to secondary master controller A1-1, then, sub-control A11 sends enabling signal to the extinguishing device F1 of an area of fire protection rapidly, extinguishing device F1 spraying fire-extinguishing agent is because the particular surroundings of cable tunnel can not use the water that can conduct electricity as extinguishing chemical, can only use nonconducting material such as dry ice powder, can avoid cable conduction that the bigger condition of a fire takes place like this.After extinguishing device F1 started, secondary master controller A11 issued described processing unit with a feedback signal immediately.
At this moment, shown in the panel display as shown in Figure 4, the area in the panel display of master controller outside: 1 signal lamp is bright, promptly represents area of fire protection No. one, the door number: 1 signal lamp is bright, promptly represents fireproof door 01
#Door is closed.
Centralized displaying warning device in the control room outside the cable tunnel also shows above-mentioned information simultaneously.As shown in Figure 5, described display unit shows that also in the master controller position: the A1 lamp is bright, and secondary master controller A11 lamp is bright, represents that promptly master controller A1 and secondary master controller A11 are in control; Alarm: voice guard W11 and fire prevention gate light alarm W12 lamp are bright, and promptly these two alarms are being reported to the police, and extinguishing device: the F1 lamp is bright, and promptly extinguishing device F1 is starting fire extinguishing.At this moment, the alarm of centralized displaying device also sends alarm signal, has the condition of a fire to occur in the prompting subterranean tunnel.This alarm is installed in the centralized displaying device, and the alarm in any fire district starts, and this alarm also starts warning, and the staff of tip ground has the condition of a fire to occur.
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, 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 operation is pressed reset key and can be demonstrated simultaneously in the centralized displaying on ground.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.
Above embodiment is used for clearer explanation the present invention to be used for limiting the present invention, and every any conversion and modification of making under spirit of the present invention all belongs to the scope of protection of the invention.
