The humanity already entered for the 21st century, along with our country national economy development and comprehensive national strength enhancement, people's quality of life obtained the very big enhancement, the housing conditions and the environment also has the very big improvement. Along with the science and technology, the control technology and the communication technology high speed development and the application, the automatic control technology, 传感 the technology gradually widely are applied in the industry and the civil construction, enable the building also to have the certain intelligence. But take the network technology as core information technology rapid permeating, enormously has developed the architectural complex development space, has completed the group after group intellectualization residential district in the nation. According to the intelligent construction development demand, the country promulgates "Intelligence Architectural design Standard" to July 3, 2000, the fire auto-alarm system takes content.
Because the urban population inflates, the city land resource is deficient, in the residential district completes the large-scale comprehensive high level architectural complex, namely take the skirt room as 连体, many high level housing constructs in the skirt room, the skirt room is equipped with the market and so on the public building. Looks Beijing some plot take the Beijing northeast as the example, the total floor space approximately more than 700,000 square meters, the building underground is equipped with the garage, the skirt room is equipped with the supermarket, the commercial city, the dining, the entertainment, the bank and so on, high level partially is composed by several housing and the office. In the building the population increase, the coal gas, the domestic electric appliances equipment and in the public electric appliance equipment use the safety factor and so on, does not have the fire hidden danger, poses the very big threat to the plot inhabitant's life and the property. Therefore, the people more and more urgently request the plot property use the effective measure in the facility and the management, satisfies the safe guard request which grows day by day.
In order to effectively guaranteed inhabitant's life and the property security, introduced the intellectualized method in the comprehensive housing and in the residential district to carry on the safe guard management. The intelligent housing safe guard system mainly is (fire auto-alarm and coordinated control system) is composed by the security system and the fire protection system. Specially the high-rise construction once has the fire, creates the personnel casualty and the economic loss are extremely serious. Therefore the high-rise construction fire prevention measure especially reveals importantly.
Usually for the convenience management, the plot fire prevention center should construct in the estate management center, each group of high-rises building supposes the fire duty officers observation room, in the plot various fire duty officers observation room fire auto-alarm controller (region machine either lower position machine) (is centralized machine or on position with the fire center control main engine machine), forms a whole through the plot network company, the overall system should consider uses the disperser control, the centralized management structural configuration. Below through the engineering design, the fire auto-alarm system may achieve the function:

First, building fire-alarm system function:
According to the fire standard, supposes the feeling warm detector, the manual alarm apparatus and the fire-alarm urgent broadcast in the underground garage; In the skirt room market, the bank, the recreation area and so on place suppose the feeling smoke detector, the manual alarm apparatus, and the establishment speaker uses in usually the background music, when the fire urgent broadcast. Are partial in the high level housing, in front of the elevator public place arrangement feeling smoke detector, the manual alarm apparatus, the urgent broadcast installment and so on room, public corridor, supposes in each stair hall gate reports to the police dodges the lamp (or acousto-optics reports to the police), in the high-quality housing bedroom, the studio and the living room and so on place supposes the feeling smoke detector. 消火�?in the box is equipped with in all public places 消火�?urgently opens pumps the button.
The fire auto-alarm system linkage control (control relations sees fire prevention control logic relations table) below, it mainly has the content:
After the control system panalarm type is controlled the equipment and the equipment movement the result position and showing
The water fire prevention system 消火�?button starts 消火�?pumps the pump house
Reports to the police the valve pressure switch to start sprays pumps the pump house
The fluent display (reports to the police, determines 火层) the water 支管
The overhaul signal valve (reports to the police, reminder attention) water 支管
The fire basin water level or the water pipe pressure start, stops the steady press pump and so on
The pre- function system this region detector or the manual button start the pre- function to report to the police the valve to be filled with water this region (闭式 nozzle)
The pressure switch starts sprays pumps the pump house
The water spray system warm feeling, the smoke feeling simultaneously report to the police or the urgent button starts the rain to drench the valve to start sprays pumps (automatic time delay for 30 seconds) this region (to operate type nozzle)
Air-conditioning system smoke feeling detector or manual button closure related system air conditioner, new atmosphere machine, ordinary air feeder
Closes this electrically controlled fire protection valve
The fire protection valve 70 �?warm controls shutting down to close this system air conditioner or the new atmosphere machine, the air feeder

In the dual purpose wind tube, closes the normal platoon gusty area, 开�� smoke mouth
Discharges fume nearby the air blower to protect from fire valve 280 �?warm to control related closes the closure to discharge fume the air blower 屋面
The flammable gas reports to the police turns on a related room row of air blower, the closure gas piping valve kitchen, the gas meter room, the underground fuel gas boiler room and so on
Nearby the fire protection volume curtain gate fire protection volume curtain gate smoke feeling detector this volume curtain or this group of volumes curtain gate drops one half
Nearby the fire protection volume curtain gate warm feeling detector this volume curtain or this group of volumes curtain turn over to the bottom
The volume curtain has when the water curtain protects, the start water curtain solenoid valve and the rain drench pumps
The electric control often operates nearby the fire door the smoke feeling or the warm feeling release magnet, closes this fire door
The electric control keeps off the smoke to hang nearby the wall the smoke feeling or the warm feeling release magnet, should keep off the smoke to hang the wall or this group keeps off the smoke to hang the wall sagging
The manual primarily system manual/is automatic, manual primarily shuts off 火层 the non- fire power source 火层, about each
Manual/is automatic, manual primarily starts 火层 the alarm bell or the acousto-optics alarm device 火层, about each
Manual/is automatic, manual for instigates the elevator to turn over to the head, the fire elevator to put into the fire use
Manual carries on to the domain of dependence urgently is broadcasting 火层, about each
The fire telephone reports to the police as necessary, the contact, the direction fire fighting
1. water fire fighting system:
When 消火�?button movement, the system may be automatic manually/opens, stops 消火�?pumps, and monitors its running status. The water sprays does on the tube the pressure switch movement, the system may automatically start sprays pumps, and monitors its running status.
Supposes the water atomization fire fighting system in the underground fuel gas boiler room, the water spray uses the type nozzle, in the room supposes several groups of feelings smoke, the feeling warm detector composition. When feels the smoke, the feeling warm detector simultaneously reports to the police, the system passable has been automatic, manual and the emergency operation three ways, opens the rain to drench the solenoid valve. After the pressure switch movement the system initiation sprays pumps, and monitors its running status.
Supposes the water in the underground garage to spray the pre- function system, the water spray uses 闭式 the nozzle, in the water pipe fills the air, when feels the warm detector reports to the police, the system is automatic/manually opens on the water pipe the solenoid valve to be filled with water, after the nozzle broken water pipe deflates, does the pipe pressure switch movement, the signal returns to the fire duty officers observation room automatic/manual start to spray pumps, and monitors its running status.
2. guards against discharges fume the system:
After the system confirmed has the fire, is opening 火层 and its on, the lower level positive pressure blow valve immediately (mouth), simultaneously automatically opens the top layer correspondingly to pressurize the air blower, causes in front of the staircase the room channel is a positive pressure, prevented the haze invasion, guaranteed the personnel scattered escapes the time environment security. In each corridor, the basement and the non- window room suppose the persevering to shut the fire protection to discharge fume the valve (mouth), when fire, but is automatic or manual opens the fire region the fire protection to discharge fume the valve (mouth), simultaneously the linkage corresponding discharges fume the air blower to start, when the top layer discharges fume in front of the air blower fire protection to discharge fume the mouth temperature to achieve when 280 �? the valve shuts down, a linkage row of air blower also also shuts down.
3. fires accidents broadcast system:
After the system confirmed has the fire, the system may the automatic turnoff background music broadcast, or on the fire duty officers observation room control cabinet the hand control, is putting through 火层 and its on, the lower level speaker carries on the urgent broadcast, in the instruction building the personnel disperses.
4. elevators forced landings system:
After confirmed has the fire, the system immediately forced landing all elevators to first, and the automatic turnoff guest, the goods elevator power source, only retain the fire elevator to use for the fire fighter.
5. volumes curtains gate control:
When on the fire protection channel volume curtain gate two side feeling smoke detector reports to the police, the systems control volume curtain gate drops to is apart from ground 1.8m place, keeps off the smoke and lets the personnel disperse. When the volume curtain gate two side feeling warm detector reports to the police, then the systems control volume curtain gate drops the ground, completes the fire warden the separation. The volume curtain gate nearby two also is equipped with the volume curtain gate control fluctuation the button, after and is equipped with the maintenance time delay (1-30 second to be possible to adjust) the function which the volume curtain gate automatically lays down.
6. other linkages controls:
After confirmed has the fire, the system will meet manual/is automatic 火层 and its on, the lower level reports to the police dodges the lamp or the acousto-optic alarm apparatus starts, in the reminder building the personnel promptly will disperse, and manual will be shutting off 火层 and its on, the lower level non- fire power source by the fire duty officers observation room.

Second, plot fire-alarm system network function nf
The plot fire-alarm system network goal, is causes the management information and the control information integration adapts this plot fire-alarm system disperser control, the centralized management demand. The fire center is equipped with the large-scale community fire prevention simulation plate, demonstrated various buildings detector reports to the police the situation, various fire facility running status, as well as the execution reports to the police the control work.
The fire-alarm network system, uses in each construction fire prevention duty officers observation room supposes the substation (fire to report to the police controller), visible for network region machine (lower position machine), the fire-alarm controller except has receives this construction fire alarm, the manual/automatic output control procedure, starts various fire facility outside the lindage, but also must have the performance outstanding networking function, even if (is centralized machine or on position with the central station machine) loses the relation, also can independently complete completely works, because various buildings fire-alarm controller uses the advanced multichannel CPU microcomputer processor technology, according to respectively constructs each own characteristic, composes own reports to the police, controls the subsystem.
The central station is located in the plot fire prevention center, can demonstrate in the entire system various fire detector, the association control the installment and various substations active status.
Central station main function as follows:
A. may visit in the system each substation 监控�?
B. may complete reports to the police and reports to the police processing;
C. may monitor the on-line all equipment running status;
D. completes the linkage control according to the hypothesis procedure;
E. time and date automatic transformation;
F. reports to the police the event to analyze and to process the record;
G. document and report form;
H. fire-alarm building graphical display operation;
I. also has the security to patrol the function.
The central station is equipped with with various substations data/pronunciation network correspondence connection, the network develops the plain structure to be possible to use the star (or ring net), has two the central station to the substation to pass the fuse, is the data communication line; Is the pronunciation communication lines.

In brief, along with modern control technology, computer and network technology rapid development, the people housing conditions enhancement, in the intelligent plot many weak electricity systems, the fire auto-alarm system is essential, intelligent fire protection alarm system in plot application more and more universal, causes the intellectualized plot weak electricity system integration more perfect, the resources fully is used, function more complete, peacefully guards against the system strongly to be highly effective, thus realizes in the true significance intellectualized plot.
