Description

Technical Field

[0001] This invention relates to an automatic fire isolation device for underground parking spaces, and more particularly to an intelligent fire isolation system based on temperature sensing, precise positioning, rapid release, and platform-based management. Background Technology

[0002] As an important component of modern buildings, underground parking garages are facing increasingly prominent fire safety issues. Traditional underground parking garage fire protection systems mainly rely on smoke detectors, heat detectors, and automatic sprinkler systems, but these systems have the following technical shortcomings: (1) Response delay: Traditional smoke detectors and sprinkler systems are installed on the ceiling. The smoke and heat generated in the early stages of a fire take a long time to reach the top, resulting in alarm delay. (2) Inaccurate positioning: The fire station cannot be accurately located, which affects the fire extinguishing efficiency, and the fire is sprayed everywhere when there is a fire; (3) Poor isolation effect: The sprinkler system can only control the spread of fire, but cannot form an effective physical isolation, which can easily cause "fire to spread to other camps"; (4) Lack of intelligent management: It is impossible to achieve remote monitoring, fault diagnosis and linkage control.

[0003] The invention disclosed in application number 202311732196.9 is a temperature-sensitive explosion-proof device for new energy vehicle charging stations. It includes a fireproof cover installed on one side of the charging space, connected to a mobile device. The fireproof cover is used to cover the vehicle. A monitoring sensor and a fire extinguishing system are located at the charging space. The monitoring sensor is connected to a control system, which in turn is connected to the fire extinguishing system and the mobile device of the fireproof cover. This invention can isolate the new energy vehicle from its surrounding environment in the event of spontaneous combustion or fire, thus preventing injury to surrounding vehicles and personnel. However, this device is suitable for fixed parking spaces and requires a one-vehicle-per-station design, making it unsuitable for fire isolation and protection in parking lots.

[0004] For automatic fire isolation systems in underground parking spaces, key preventative measures and flexible handling are required. High demands are placed on the adaptability, flexibility, and rapid response capabilities of the isolation devices. Therefore, an intelligent fire isolation system based on temperature sensing, capable of precise positioning, rapid release, and platform-based management, can automatically isolate vehicles on fire. This would greatly benefit the fire safety of parking systems and effectively protect the property of the public. Summary of the Invention

[0005] This invention addresses the shortcomings of existing technologies by proposing an automatic fire isolation device and intelligent fire isolation system for underground parking garages. The device / system monitors the parking space temperature in real time using ground RFID temperature tags.
