Application of Intelligent Fire Fighting System in Intelligent Building?

With the development of economy and the progress of science and technology, there are more and more intelligent buildings around the world. At the same time, in order to ensure the safety of people and property in intelligent buildings, the intelligent fire protection system is reliable. Therefore, this paper mainly discusses the application of intelligent fire protection system in intelligent buildings.

I. Introduction

The use of intelligent fire fighting system can automatically detect the danger before the building appears, so it can effectively suppress the danger. Intelligent fire protection system can improve the safety factor of intelligent buildings, and its application scope is wider and wider, so it is necessary to further study.

Second, an overview of intelligent fire protection system in intelligent building

The general intelligent fire control system can be divided into two parts: fire control and automatic alarm system. The automatic fire alarm system is mainly used to find and solve hidden dangers in time before they appear, so it can effectively maintain the safety of people and property in buildings. After the danger is discovered, the automatic fire alarm system can send a signal to the automatic control system in time, and then the specific fire fighting work is still commanded by the school control system, and the alarm system and the fire fighting system do not interfere with each other. With the research and application of intelligent fire protection system in China, the disadvantages of this design method are gradually discovered, especially the independent existence of fire protection system leads to its certain rigor, which will limit the fire protection system to some extent and hinder its connection with other systems. The problems in this design will directly affect China's social and economic development. In the current intelligent building design, it is necessary to further study the application of intelligent fire protection system in order to further protect personal and property safety [1].

Third, the organizational structure of intelligent fire protection system

The general intelligent fire fighting system consists of fire detection equipment, fire alarm equipment and other equipment. 1. Fire detection equipment is in a key position in the control system. The main function of this equipment is to monitor whether there will be a fire in the building. If a fire is detected, the detection equipment can directly convert physical signals such as temperature and light intensity into electronic signals, and then directly transmit these signals to the control system. 2. Fire alarm equipment The fire alarm equipment is also a very important equipment in the whole fire protection system, especially it can analyze the signals from the detection equipment, and after the analysis, it can be linked with related equipment.

Fourth, the control mode of linkage system

Generally speaking, there are three control modes of linkage system, and fire alarm equipment should be considered in the process of selecting linkage mode. 1. General branch linkage control system The general branch linkage control system is generally a bus connected by the control center and various devices, so the connection between the devices is a chalk line. The system is mainly suitable for the environment with large height but small area. 2. All bus control systems are buses, which means that this system will be equipped with corresponding control modules, so its overall structure is relatively simple, and the production cost is higher than that of the total control system [2]. 3. The number of buses in the hybrid control system is relatively small, the control function is relatively complex, the system debugging or maintenance is difficult, and the use frequency is low.

The Design of Main Function Modules of verb (abbreviation of verb) System

1. fire alarm controller module

The fire alarm controller module used is mainly GST-200 linkage fire alarm controller. The main function of this controller is dual-core computing, and it has strong processing ability, which can support up to 242 control areas and can also form a digital control network. Manual startup disk and bus devices on its related controller panel can complete manual control of bus devices. In addition, it should be noted that the controller can automatically control the peripheral devices by changing the linkage formula of the controller.

2. Fire detector and manual alarm module

Combined with the basic characteristics of fire, the detector and alarm module include several basic components, such as temperature difference detector, photoelectric smoke detector and manual alarm button. Usually, fire detection is based on the infrared scattering principle of smoke detectors. If a certain concentration of smoke is detected, it will call the police directly. The temperature difference detector is based on the principle of thermistor sensor. If the internal control chip detects a fire, it will send an alarm message to the controller, and the fire alarm indicator will light up.

3. Input/output driver module

There are a pair of normally open and normally closed contacts in this module, so it can output 24V DC voltage and form passive or active output with the contacts of relay. The module also has the function of switching signal input, so it can achieve the goal of connecting with field devices, so as to check and confirm whether the field devices are acting at any time. Among them, the input and output modules can also be used to drive executive devices, such as shutter doors and fire dampers. In the process of connecting with the control bus, closed-loop control can be formed [3].

Six, the main reasons for the problems of intelligent fire protection system

1. Problems in fire protection design

General fire protection design is a complicated process, especially through preliminary design and design modification, until the final design is completed. Fire protection design is generally completed by many people or units, so there are often some problems in the design process. For example, in the process of preliminary design, it will depend on the basic structure of the building, so it will be combined with the architectural design drawings for fire protection design, but sometimes the control problem of linkage equipment will be ignored. In addition, in the process of installing fire protection system equipment, there will also be problems of not reading carefully, which will affect the design effect. If every link of the design is not done well, it will affect the final design effect, so in the process of fire protection design, the details can not be ignored.

2. Construction quality problems

After the intelligent fire protection design, we need to consider the construction problem. If there is no reasonable construction, it will directly affect the building. Some construction workers do not have professional quality, and the materials used will be unqualified, which will directly affect the construction quality. For example, some cable connectors are not installed according to the standard, which will leave some security risks. In addition, in the process of selecting intelligent fire protection design system, the installation regulations should be strictly implemented. For example, in the process of connecting multi-core software, knowledge uses ordinary BV single hard wire, which will eventually lead to short circuit and greater building safety risk. In addition, this kind of wiring is also difficult, which easily leads to the phenomenon of virtual connection, thus causing obstacles in the process of troubleshooting.

Seven, intelligent fire control system failure related countermeasures.

In the process of using intelligent fire protection system, we often encounter various problems, such as system design, equipment, materials, etc., which often lead to some mistakes and ultimately affect the use of fire protection system. Faced with these problems, we need to take some measures.

1. Improve the design of intelligent fire fighting system

In the process of designing intelligent fire protection system, many factors need to be considered, especially drainage, wiring, heating and ventilation. Before design, the design unit will design the fire protection system according to the design power of attorney provided by the owner. The design of intelligent fire fighting system is generally completed by one or more units. The design of this system mainly belongs to a specialty of weak current, so it involves many devices in the linkage system. In the process of designing intelligent fire protection system, it is necessary to consider the intelligent fire protection system as a whole. If you need to change the design, you need to pay attention to every detail change. In the process of system design, the design unit should not only have professional technical knowledge, but also have a full understanding of fire protection knowledge, and at the same time, it should also make clear the specific construction specifications and fire protection design specifications.

2. Choose good mechanical equipment materials.

In the installation process of intelligent fire protection system, it is necessary to have enough knowledge about the equipment and materials of intelligent fire protection system, including the production and use of various mechanical equipment and materials and the performance of the equipment before use, so as to make better use of it on the basis of understanding. In addition, we must be fully familiar with the actual characteristics of building fire protection, and then choose appropriate equipment and materials, and ensure the economic rationality in the design process of intelligent fire protection system. The selected equipment should have good performance, ensure its stable operation and signal transmission quality, and pay attention to close cooperation with other systems.

Eight. conclusion

In order to ensure the reasonable design and use of intelligent fire protection system in intelligent building, all details need to be considered, especially to ensure the safety and reliability of the system, and pay attention to strengthening the design and debugging of intelligent fire protection system to ensure that the intelligent fire protection system can play its greatest role.
