Structure and function of intelligent fire supervision system for cultural relics and ancient buildings;

1, system architecture

The overall architecture of the intelligent fire protection system includes the sensing layer composed of hardware detectors and sensors of the Internet of Things, the transport layer of network transmission modes such as NB, lora, gateway, 4G and 5G, and the service layer and application layer.

First, the perception layer

The sensing layer is a comprehensive application of RFID radio frequency technology, temperature sensing, smoke sensing, power parameter monitoring and other wireless sensing technologies. , get the basic big data of fire protection, and realize the basic perception in fire protection work, such as the collision damage of fire hydrants and the need to replace fire extinguishers when they expire, which can be found in time by using sensing technology.

The perception layer automatically collects all kinds of data information in the fire protection system through the perception and recognition technology, which is the most unique difference between the integrated security Internet of Things and other networks. The perception layer of fire-fighting Internet of Things is mainly composed of various sensor networks such as fire alarm, video monitoring system and wireless detector. The fire alarm system collects data through the data interface of the equipment, interacts with the data center through wireless or wired mode, and extracts the state information such as detector alarm, equipment failure, equipment action and shielding sent by the controller in real time. For the fire water system, various pressure, water level, current, voltage and temperature and humidity sensors can be installed to monitor the operation parameters of key equipment.

B, transport layer

The transport layer uses mobile information technology to realize data transmission. The development of mobile information technology has greatly promoted the application of Internet of Things technology in various industries. The most obvious performance in fire fighting work is power consumption monitoring. The changes of temperature rise, leakage, current, voltage and other parameters can be obtained in real time through information technology.

The transport layer transmits the information obtained by the perception layer to the service layer. As an important infrastructure of the Internet of Things, the transport layer includes all wireless and wired, long/short distance communication systems. The transport layer solves the transmission problem of data obtained by the perception layer. These data can be networked separately or mixed through mobile communication network, TCP/IP private network, public broadband network and public telephone network.

C, application layer

The application layer processes the obtained big data of fire basic perception to realize specific applications, such as the monitoring and management of fire water system, the analysis of video monitoring, the summary, analysis, judgment and application of fire data such as fire alarm information. Provide information support for fire control work. As the deep integration of the Internet of Things technology and the professional technology of the fire protection industry, the application layer realizes the intelligence of the fire protection industry in combination with the needs of the industry. The application layer of consumer Internet of Things provides users with rich specific services by analyzing and processing the perceived data.

? D, service layer

The service layer processes the data information transmitted by the transport layer, and provides application services to external users. Combined with new technologies such as big data and cloud computing, it provides users with more efficient and convenient services.

In order to realize the modernization of the operation and supervision of fire facilities, it is necessary to build an effective intelligent fire monitoring Internet of Things system, adopt all kinds of sensing devices and video acquisition devices in the automatic fire alarm system, transmit a large amount of field information collected by sensors to the fire command center through the Internet of Things, and transform the closed and single-function fire alarm system into a grid and intelligent cross-regional fire alarm integrated management platform.

Wisdom fire control of ancient cultural relics

2. System introduction

The intelligent fire protection system for cultural relics consists of intelligent fire safety hidden danger inspection system, intelligent fire power hidden danger monitoring system, intelligent fire water monitoring system, independent smoke alarm, intelligent fire visual networking alarm system, intelligent combustible gas detection alarm and intelligent fire online training platform.

Intelligent fire safety hidden danger inspection system

Intelligent monitoring system for hidden dangers of fire-fighting electricity: an integrated management system that can realize controllable daily spot inspection, fault inspection and location of passive fire-fighting equipment (such as fire extinguishers, fire hydrants, fire doors, etc.). ) with the help of civil air defense and NFC passive identity ID. System functions: patrol inspection, equipment positioning management, fixed assets management, life cycle and spot check.

Intelligent fire water monitoring system: independent wireless acquisition equipment is used to monitor the fire water system, monitor the pressure of fire hydrant pipeline, the open and close state of fire pipe network valves, the open and close state of fire pumps, etc. The platform management mode is adopted to centrally manage a large number of offline devices, and the functions of early warning, positioning and maintenance of devices for multi-role users are realized on a unified platform. Support PC and mobile terminal, dynamically monitor and present the safety status of fire water system in three dimensions.

Independent smoke alarm: the intelligent smoke detector is connected with the intelligent fire fighting system through various network transmission modes. When a smoke alarm occurs, in addition to the acousto-optic alarm itself, the smoke alarm information will be sent to the intelligent fire-fighting cloud platform to realize the second-level response of the alarm information. Fire control room personnel and regional administrators will receive smoke alarm information through computer screen or mobile phone APP or mobile phone short message. They will also send it to 168 if it is not handled within the set time.

Intelligent visual networked fire alarm system: advanced technologies such as digital video compression technology are adopted to monitor the operation of fire exits and evacuation exits, fire duty control room, mini fire station, etc. It also uses image pattern recognition technology to analyze and alarm fire and burning smoke, and supports access to the existing video monitoring system, so that managers can quickly understand the dynamic video information of monitoring points at the first time.

Flammable gas monitoring and alarm system of fire-fighting Internet of Things: designed according to the gas characteristics of the application site, generally taking methane as the standard. With the application of Internet of Things module and wireless transmission technology, combustible gas detector can realize wireless connection with intelligent fire-fighting cloud platform, and all real-time data of gas can be obtained through fire-fighting Internet of Things system. When there are abnormal situations such as leakage and rising gas concentration, the system will automatically give an alarm, and notify relevant personnel through telephone, SMS, system pop-up window and other forms, and quickly arrive at the alarm site for disposal.
