0 . Preface

With the economy 、 The rapid development of science and technology , People began to pursue the humanization of architectural facilities 、 Rationalization , A large number of high-rise super large buildings , And the emergence of underground buildings has led to longer building passages 、 More complicated . With the improvement of people's safety awareness , Based on people-oriented 、 The idea of putting life safety first , For people intensive 、 Long evacuation distance 、 There are many evacuation routes 、 Many turns 、 Buildings with complex environment , The traditional evacuation mode cannot be used for timely maintenance of lamps , When the fire broke out , There is no reasonable guidance for personnel evacuation and escape , Therefore, implement a rapid and reasonable safety evacuation system , Guiding personnel to escape in time is an important measure to avoid causing mass casualties , In this way, centralized emergency lighting and evacuation indication system came into being .

The centralized emergency lighting and evacuation indication system can accurately realize the real-time monitoring and control of all emergency lamps 、 daily 24 Hourly management and maintenance , Ensure the normal operation of the system , Safety in case of fire 、 accuracy 、 Quickly guide personnel to the safe area , Reduce casualties .

1. Industry Introduction

1.1 Industry background

The medical industry is an industry closely related to the life and health of residents , Modern hospital buildings tend to be high-rise 、 Large scale and complexity , It is the complex functions used in all buildings 、 One of the buildings with high safety requirements . Hospitals belong to social public service places , Vulnerable groups of patients are concentrated 、 There's a lot of traffic , The connection of passages in the building is complex , Bedding 、 paper 、 There are many inflammables such as chemicals . There are many kinds of medical equipment in the hospital, and the power load is large , Social medical institutions are developing rapidly , Help people get out sick , However, many potential safety hazards cannot be ignored , In case of fire , It will cause huge property losses and casualties .

1.2 Industry standard

1.3 Regional division and regional characteristics

According to the demand of different areas in the hospital building for emergency lighting and evacuation instructions, it can be divided into three areas , For example, the architectural division of a hospital ：

1.  Conventional areas ： Such as the office building in the hospital 、 Living quarters 、 Inpatient building, etc , There is no special need for emergency evacuation lamps in the area .

2.  Personnel flow area ： This area is generally registered 、 Payment hall , There is a large flow of people in the area , The place is empty , Personnel are unfamiliar with the building structure , High dependence on evacuation indication system during evacuation .

3.  Clean area ： There is a certain cleaning demand for the equipment in this area , Such as the clean passage in the operation Department . 

 

2.  Project introduction

2.1 Project brief introduction

This project is a hospital project , With internal medicine 、 Surgery 、 Orthopedics and traumatology 、 Anorectal 、 Department of gynaecology 、 Pediatrics and other departments , It is divided into emergency building 、 Outpatient building, inpatient building and other buildings . Our company is responsible for the inpatient building of emergency medicine in the second phase project of the hospital , Including its underground buildings , Most of them are conventional areas and personnel flow areas . Fire emergency evacuation indication system is required for emergency evacuation signs in all places , When a fire or emergency occurs , The specific fire location can be detected through the smoke detector of the fire monitoring system , And transmit the command to the fire host of the system by means of communication , Point to... With the arrow of the evacuation sign in the control place , Ensure that personnel escape and evacuate in the right direction .

2.2 Project difficulties 、 Special point

Ø  The building density in the hospital building area is high 、 Many divisions , There are many internal fire compartments , The circuit of lamps is complex , How to arrange the fire emergency lighting and evacuation indication system

Ø  In case of an emergency, the evacuation speed of patients in the inpatient building is slower than that in other places , Some patients with special conditions also need a stretcher or help to leave slowly , For evacuation lighting in this area , Determination of emergency time

3. Introduction to system scheme

3.1 Scheme topology

 

Combined with the inpatient building project of our hospital , The inpatient building includes conventional area and personnel flow area , Usually the first floor is the registration and toll area , The flow of people is large , The requirements for evacuation signs are mostly in case of emergency , It can be clearly seen in the chaos of the scene . Other floors are inpatient wards of different departments , The staff are mostly medical staff 、 disease 、 Caregivers , Consider the patient's ability to move , Appropriately extend the emergency time of lamps . There are staircases and less open areas in the inpatient building , Consider the need for energy conservation , Properly install induction lamps .

3.2 System software operation interface and function

Main interface of system operation

 

Contains toolbars 、 Graphic display 、 Layer list 、 status bar , You can intuitively view the operation status of the monitoring equipment , And switch directly to the specific fault bit according to the actual content of the status bar .

Lamp configuration interface

 

You can view the status and quantity of all lamps

Event recording interface

 

You can view historical operations 、 Fault information , You can query by date

 

3.3 Regional product use demand

3.4 System composition  

The fire emergency lighting and evacuation indication system is controlled by the controller （ host ）、 Centralized power supply / Distribution box and lamps （ Evacuation indicating lamps 、 Emergency lighting fixtures ） Wait for several parts to make up .

 

The controller is the host of the fire emergency lighting and evacuation indication system . The controller monitors each terminal in real time through the bus network , It can report the fault of each equipment and lamp in real time . In case of danger , Automatically issue information instructions to each terminal , The terminal starts working after receiving the instruction , Such as stroboscopic 、 open 、 Turn off the lights, etc , Real time indication of safe evacuation routes .

Centralized power supply is a standby centralized emergency power supply device installed in the building . When a building fires 、 In case of accident or other emergency , The emergency power supply can be the fire sign lamp 、 Emergency power supply shall be provided for lighting lamps , Ensure the normal operation of fire emergency lighting and evacuation instructions .

The distribution box is a power supply device installed in the building . When a building fires 、 In case of accident or other emergency , The distribution box can be a fire sign lamp 、 Lighting power supply , Ensure the normal operation of fire emergency lighting and evacuation indication system .

Emergency lighting fixtures provide lighting for personnel evacuation . The installation method is wall mounted 、 Ceiling type 、 Embedded type .

The evacuation indicator lamp guides the direction of personnel evacuation , To the left 、 Right and two-way sign lamps are generally used to indicate the direction of evacuation , Directional sign lamps are generally used to indicate emergency exits 、 Floors and shelters . The installation method is wall mounted 、 Hanging type 、 Buried .
