This system product is applicable to residence 、 School 、 The hospital 、 Exhibition Hall 、 Hotels and other places .

【 key word 】： Fire door monitoring system ; Normally open fire door ; Normally closed fire door ; residential  

0 . Preface

With the economy 、 The rapid development of science and technology , The density of people in cities is increasing , In case of fire , Quickly isolate the fire source , Reasonably control the scope of fire , It can create good conditions for fire fighting and personnel evacuation . therefore , Fireproof partitions such as fireproof doors are widely used in the fire protection design of construction projects , But its design is unreasonable 、 Improper model selection 、 Inadequate monitoring and other reasons , So that the fireproof door can not give full play to its isolation function . Therefore, real-time monitoring and control of the working state of the fire door , It is an important measure to prevent the spread of fire and smoke , Therefore, the fire door monitoring system came into being .

Fire door monitoring system is a new product in the field of fire safety , It integrates industrial computer technology 、 Communications 、 Anti electromagnetic interference 、 Digital sensor technology and industrial fieldbus control technology in one of the intelligent system , The working state of the fire door can be 24 Hour real-time automatic patrol inspection , Give alarm prompt to the fire door in abnormal state . In case of fire , The monitoring system automatically closes the fire door , Win valuable time for fire rescue and personnel evacuation .

1. Project introduction

The project is a residential project , from A2-1 Land and A3-1 The composition of the plot , See Table 1 for the distribution of buildings .

among ,A2-1 The upper part of the plot is 5 A first-class high-rise residence （1-1# floor 23 layer 、1-2# floor 25 layer 、1-3# floor 25 layer 、1-4# floor 26 layer 、1-5# floor 26 layer ） and 2 A multi-storey public building （1-S1# The building is 3 Layer business ,1-S2# The building is 2 Transformation and distribution room on the first floor ）; The basement 1 layer , Pump room is set locally 、 Cable TV room and other equipment rooms , The rest serve as garages , Small motor vehicles can be parked 565 car , Non-Motor Vehicle 838 car , Belong to Ⅰ Automobile like garage . The underground construction area is about 12782.63m2 , The ground floor area is about 51909.74m2, Gross floor area 64692.37m2, The total height of the building is as high as 76.05m, It belongs to class II residential land .

A3-1 The upper part of the plot is 5 A first-class high-rise residence （2-1# floor 21 layer 、2-2# floor 22 layer 、2-3# floor 22 layer 、2-4# floor 23 layer 、2-5# floor 26 layer ） and 1 A multi-storey public building （2-S1# The building is 1 Layer business 、2 Transformation and distribution room on the first floor ）; The basement 1 layer , Pump room is set locally 、 Cable TV room and other equipment rooms , The rest serve as garages ( Peace and war ), Small motor vehicles can be parked 509 car , Non-Motor Vehicle 710 car , Belong to Ⅰ Automobile like garage . The underground construction area is about 12486.82m2 , The ground floor area is about 46739.78m2, Gross floor area 59226.6m2, The total height of the building is about 76.05m, It belongs to class II residential land .

2.  Site requirements and product solutions

2.1  Fire door monitoring module requirements

2.1.1 Fire door monitoring module site requirements

According to the needs of customers , In the front room of the elevator where people often pass , Normally open fire doors shall be provided ; Normally closed fire doors are generally set at the stair entrances ;

2.1.2 Fire door monitoring module product scheme

Product application matching scheme ; See the table below 3.

surface 3： List of fire door monitoring module selection

2.2.1 On site host and extension requirements 2.2  Fire door monitoring host and extension requirements and solutions

According to the table 1 And graph 1 The needs of , We need to be in A2-1 Land and A3-1 A set of fire door monitoring host is set in each plot , Then set up a set of regional extensions in each building for networking .

2.2.2 Host and extension scheme

  

Fire door monitoring host

Area extension

See the following table for parameters of fire door monitor and area unit 4 And table 5

surface 5： Parameters of the area extension

2.3  System requirements and solutions

2.3.1 System requirements and solutions

Precautions for system networking  

① Communications ： host - extension ：CAN Bus ,500 rice , Each circuit ≤32 platform

host - modular ： Two bus ,  500 rice , Each circuit ≤64 platform

② Bus condition ：CAN Bus ：NH-RVSP2*1.5mm²

         Two bus ：NH-RVSP2*2.5mm²

③ Wiring way ：CAN Bus ： Hand in hand

             Two bus ： Hand in hand 、 Star type 、 Tree shape   Equal connection method

2.3.2 software interface

contain “ land ” Button 、“ Interface title ”、“ Function list ”、“ System status bar ” Four-part composition , You can quickly query the current monitoring status , It can also be used for staff login .

User login interface

      After entering the correct user name and password , The system status bar will directly jump to the current user's operation interface , It can display the list of currently logged in users and functions .

Permission management interface

This interface has three operation levels , New users of lower level can be added to those with higher operation permission level .

Condition monitoring interface

This interface intuitively displays the fire door icon in a graphical way , The system will display the details of the fire door .

4. Conclusion

With the development of China's economy and society , The security problem has attracted more and more attention , People gradually realize that the fire door monitoring system plays a very important role in the occurrence of fire . therefore , This system has a broad market prospect , And is becoming a sunrise industry in the field of fire protection , Ankerui electric focuses on building products of various fire security systems , On the premise of meeting the requirements of national industrial standards , Provide intelligent services for all kinds of buildings 、 reasonable 、 Energy saving 、 Cheap fire-fighting solutions and products , For fire prevention and disaster reduction 、 Make a contribution to ensuring the safety of people's lives and property ！
