Application of fire emergency lighting and evacuation indication system in a pharmaceutical plant project

【Abstract】:Fire emergency lighting and evacuation indication system consists of several parts,
such as controller, centralized power supply/distribution box and lamps (evacuation indicator lamps, emergency lighting fixtures).

The system adopts Windonws7 system, which can support linkage alarm, system monitoring, fault alarm, self-test, power backup, record storage and query, light guide stream, authority control and other functions, with centralized control, high flexibility and strong reliability
.

With a variety of installation methods, a variety of protection levels of signs and lights, can be applied to the building area of the internal fire protection partition, lighting circuit long plant projects
.

With the rapid development of economy and technology, people began to pursue the humanization and modernization of building facilities, and the emergence of a large number of large buildings and underground buildings led to longer and more complex
building passages.

With the improvement of people's safety awareness, in line with the idea of people-oriented, life safety as the most important, for the densely populated, long evacuation distance, many evacuation channels, many turns, and complex environmental buildings, the traditional evacuation indication method can not find the failure of the lamp in time, and timely maintenance and management
of the lamp.

In order to ensure that the equipment is in a normal state when the fire occurs, can work normally, the implementation of rapid and reasonable emergency evacuation system, centralized control type emergency lighting and evacuation indication system came into being, can accurately realize the real-time monitoring and control of each emergency lamp, daily 24-hour management and maintenance, to ensure that the system operates normally, in the event of a fire accurately and quickly guide personnel to the safe area

Project Introduction 1.
1 Project Introduction This project is a medical plant and engineering building project, the project includes two workshops and two engineering buildings, and the company is responsible for the emergency lighting and evacuation indication system
of the second phase of the workshop and engineering building.

Among them, there are areas where Class A and B hazardous substances are used in the workshop plant, and the equipment in the area should meet the relevant provisions
of GB50058 "Design Code for Electric Power Devices in Explosion Hazardous Environments" on the division of explosion hazard areas.

When a fire accident occurs, the specific fire location can be detected through the equipment of the fire monitoring alarm system, and the instructions are transmitted to the evacuation controller of the system to control the arrow of the evacuation sign in the place to ensure that the personnel escape and evacuate
in the right direction.

2 The special point project of the project is divided into explosion-proof areas, and the fire is easy to cause large-scale combustion, forming a flowing fire, and it is difficult to extinguish the
fire.

For lamps and lanterns in this area, it is required to have explosion-proof functions; The project fire automatic alarm system requires the linkage of switching divisions, and the multi-channel switching signal needs to be converted into an RS485 signal and uploaded to the emergency evacuation controller

System scheme introduction 2.
1 Scheme topology For the above industry characteristics, the system design generally considers the design of centralized control type system
.

The controller is set up in the fire control room; Then according to whether there is a distribution room, a strong power well, a cable shaft and other areas in the field area, select a centralized power supply or distribution box
.

Different areas of the project have different requirements for emergency luminaires and switch partitions when the controller host needs to convert the module, and the system topology thus composed of it is shown in Figure 1: Figure 1 scheme topology figure 2.

3 The event recording interface can view the historical operation and fault information under this page, and can be queried by date, as shown in
Figure 4 below.

Figure 4 Event recording interface 2.
4 The system consists of several parts, such as fire emergency lighting and evacuation indication system, such as controller (host), centralized power supply/distribution box and lamps (evacuation indicator lamps, emergency lighting fixtures
).

The controller is the system host
of fire emergency lighting and evacuation indication systems.

The controller monitors each terminal in real time through the bus network, and can report the fault
of each device and luminaire in real time.

In the event of a dangerous situation, the information instructions are automatically issued to each terminal, and the terminal begins to work after receiving the instructions, such as strobosis, on, lights out, etc.
, and indicates the safe evacuation route
in real time.

A centralized power supply is a standby centralized emergency power supply unit
installed in a building.

When a fire, accident or other emergency occurs in a building, the centralized power supply can provide emergency power supply for fire signs and lights to ensure the normal operation of
fire emergency lighting and evacuation instructions.

A distribution box is a device installed in a building to provide power for fire emergency lamps
.

The distribution box can provide main electricity and battery charging for the fire emergency with battery sign lights and lighting lamps to ensure the normal operation of
the fire emergency lighting and evacuation indication system.

Fire emergency lighting fixtures provide evacuation lighting for evacuation and
escape.

Its installation methods are generally wall-mounted, ceiling-mounted, and
in-mounted.

Fire emergency indicator lamps for personnel evacuation escape direction, direction signs and lamps are generally used to indicate the direction of evacuation, such as: left, right and two-way
.

Directionless signage luminaires are generally used to indicate safety exits, floors and shelters
.

Its installation methods are wall-mounted, hanging and buried
.

Conclusion With the rapid development of China's economy and the continuous progress of science and technology, the importance of building intelligence and building fire protection has also increased, this paper briefly introduces the company's system scheme for fire emergency lighting and evacuation instructions in the pharmaceutical industry, and analyzes the application of the program in practical projects in combination with the completed projects, showing the advantages
of simplicity, flexibility, stability and low cost in the networking of such projects.

Through this system, it can solve the problems of traditional fire emergency evacuation indication system without centralized control, fixed indication direction, evacuation line can not be changed, indication effect is not ideal, low safety performance and so on
.

Ankerui Electric strives to create all kinds of fire security system products, under the premise of meeting the requirements of national industry standards, to provide intelligent, energy-saving, cheap fire protection solutions and fire protection products for all kinds of buildings, and to make a contribution to fire prevention and disaster reduction, and to ensure the safety of people's lives and property!
