Description

Remote controlled safety door centralized control system
Technical field
The utility model relates to a kind of security protection and fire plant, relate to the integrated automatic centralized control system of a kind of safety door particularly, solve the multiple different mode control and management of safety door demand, and further related to a kind of multi-functional, diversification automatic control system based on local area network technology.
Background technology
In recent years, the generation of fire failure is hindered at the dead group of the particularly serious fire of prevention especially group by country, and how effectively to control the condition of a disaster, reduces the bigger harm that brings because of fire spreading, and the protection person and property safety have been formulated a series of standard and article system.Activities such as workshop, warehouse, employee dormitory " three-in-one " factory building, refuelling station and the security against fire special administration of public gathering place have successively been carried out in China, a large amount of disaster hidden-troubles have been eliminated, obtained certain effect, but the dead group of some especially big groups hinders fire failure and still happens occasionally, and various disaster hidden-troubles are still many.One of them distinct issues is, some crowded place safety doors (fire-proof doors such as fire exit, emergency evacuation door, emergency exits, passageway for fire apparatus door) or blocked or locked or closed by the gate inhibition, in case breaking out of fire, evacuation is obstructed, and very easily causes the dead group of group to hinder serious consequence; Be exactly that each floor safety door should be able to be closed after breaking out of fire automatically in addition, stop the invasion and attack of dense smoke raging fire effectively, but reality allows of no optimist, because people generally are ignorant of fire-fighting general knowledge, do not know the effect of fire-proof door yet, ignored the threat of the raging fire that produces thick smoke after the breaking out of fire, naturally and understandably formed a kind of " habitual error behavior ", or the safety door that will often open (hold-open door) is done into normally closed type, the frequent switch of people causes fire-proof door and accessory life-span to subtract greatly, deformed damaged, What is more, simply uses timber wedge, the mop rod, objects such as fragment of brick are fire-proof door even at the cost of one's life, and making it run into fire can't close automatically, can not play due effect, fire-proof door has been become genuine deaf person's ear---ornaments.
Safety door is divided into open in usual and normally closed type according to opening, and the fire-proof door on the fire escape is generally open in usual, and the evacuation that has the safety precaution requirement to need the control personnel to come in and go out at ordinary times is generally normally closed type with door.
Regulation according to national relevant specification, the daily opening that should be of safety door open in usual, the door body has automatic closing function when meeting fire, and bivalve door should have the function of closing in order, and shutdown signal should be fed back to fire protection control room, play the effect every cigarette back-fire relief control the condition of a disaster.Need not use any instrument such as key to be easy to internally open when the normally closed type safety door should guarantee fire, and should sign is set and use prompting in remarkable position, accomplish that emergency evacuation is unblocked.
NFA department has proposed strict requirement to the automatic control of evacuating with fire-proof door, and with its automatically control be made as a part indispensable in the fire-fighting system, but because the limitation of conventional control devices, domestic existing structure is open in usual carries out the very few of standard with normally closed type safety door part in control and management, the fire-proof door shutdown signal is fed back to this function of fire protection control room to be rarely had and accomplishes that the national regulation clause almost performs practically no function.The emphasis of existing technical research all is the single control of open in usual or normally closed type safety door, for example patent 201210285331.5 discloses a kind of temperature-sensitive magnetic force fire-proof door release, after environment temperature rises to the customization temperature under fire condition, the mutual magnetic force of magnetic source assembly and releasing unit disappears, and fire-proof door is driven by door closer elastic force and closes; Patent 02276519.0 discloses a kind of normally closed type egress door release, and by solenoid control, the constraint that makes egress door break away from release is freely opened; Patent 200820112227.5 discloses a kind of slide rail type fire-proof door automatic opener, patent 200920136327.6 discloses a kind of fire-proof door and has closed a release automatically, patent 201120019868.8 discloses a kind of hold-open door and has closed a release automatically, patent 200720169594.4 discloses a kind of multifunction electromagnetic release, all be difficult to satisfy the control requirement different with the normally closed type safety door open in usual, and the solution of one is open in usual and the physics contradiction of normally closed type safety door on fire-fighting and safeguard management.
At the problems referred to above and safety door (exit door, emergency evacuation door) new period management characteristic, according to country " Code for fire protection design of high rise buildings GB50045-95 ", " Code for fire protection design of buildings GB50016-2006 ", " Code for design of automatic fire alarm systems GB50116-98 ", the regulation of " crowded place management of fire safety GA654-2006 " and " gateway control system technical requirement GA/T394-2002 ", develop complete " the safe door control management system " of a cover, use gate inhibition's control technology, the video monitoring technology, the intrusion alarm technology, fire-fighting link technology and network communications technology etc., make the management of safety door accomplish organic combination in fire-fighting and security protection, the integrated multiple different control and management demands of building safety door that solved become the task of top priority.
