Description

Technical Field

[0001] This utility model relates to the field of fire protection facilities technology, specifically to an intelligent fire detection and fire-fighting linkage system. Background Technology

[0002] A fire detection and fire suppression system is an automated system used to detect fires at an early stage and take corresponding fire-fighting measures. It monitors fire characteristic parameters in the environment in real time using various detectors. Once a fire is detected, the system quickly issues an alarm and automatically or manually activates a series of fire-fighting devices to control and extinguish the fire, minimizing the losses caused by the fire.

[0003] In large buildings or complex locations, multiple fire detection and fire suppression systems of different brands and models may be installed simultaneously. Due to differences in communication protocols and interface standards among these devices, compatibility and integration between systems are often poor. Effective information sharing and collaborative operation between different devices may be impossible, impacting the overall performance of the entire fire detection and fire suppression system.

[0004] Existing fire detection and fire suppression systems typically feature intelligent devices equipped with advanced automated control and monitoring functions, often with complex user interfaces. Remote control and adjustment of some intelligent fire suppression devices require specific procedures, which, in the tense atmosphere of a fire, may prevent personnel from quickly completing these operations, potentially causing them to miss the optimal firefighting opportunity.

[0005] Smart devices generate a large amount of fire information during operation, such as fire location, fire size, and smoke concentration. However, the transmission of this information may be untimely, inaccurate, or incomplete. The normal operation of smart devices relies on complex electronic circuits and software systems; in the event of a malfunction, timely manual firefighting is still necessary.

[0006] Therefore, a more intelligent and compatible fire detection and fire-fighting linkage system is needed to solve the compatibility and integration issues of various brands and models of fire-fighting equipment, as well as the compatibility issues between automated and manual fire extinguishing. Utility Model Content

[0007] The problem this utility model aims to solve is to overcome the defects of the existing technology and provide an intelligent fire detection and fire-fighting linkage system. Through the design and layout of the system, it achieves compatibility with various fire-fighting facility models, various signal detection modes, various equipment communication modes, and various fire-fighting intervention modes, thus greatly improving its applicability.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] An intelligent fire detection and fire-fighting linkage system comprises a linkage control cabinet and several field control boxes, fire detectors, and fire extinguishing devices. The linkage control cabinet connects to multiple field control boxes, and each field control box connects to at least one fire detector and one fire extinguishing device. Each field control box is also connected to a manual control panel. The linkage control cabinet is equipped with a multi-channel signal module and a device parameter setting module. The field control boxes are equipped with a signal acquisition module, a device control module, and a remote control fire extinguishing module. The fire detectors are equipped with a communication interface module, and the fire extinguishing devices are equipped with a fire extinguishing device communication module.

[0010] The linkage control cabinet includes a central processing module, which is connected to the multi-channel signal module and the equipment parameter setting module, and is also connected to a power supply module and a storage module.

[0014] The fire extinguishing device includes an MCU module, and is equipped with a power supply module, a fire extinguishing device communication module, a motor drive module, a valve drive module, and a status detection module, which are respectively connected to the MCU module; the motor drive module is connected to a horizontal motor and a vertical motor, the valve drive module is connected to a water spray valve, and the status detection module is connected to a water flow indicator, a signal valve, and an automatic control valve.

[0015] Preferably, the fire extinguishing device is an automatic tracking and positioning fire extinguishing device, which is equipped with an infrared sensor connected in sequence to a signal amplifier, an ADC acquisition module and then to the MCU module, and an ultraviolet sensor connected to a photoelectric module and then to the MCU module.

[0016] The manual control panel includes a display screen and a button area, which includes directional control keys, a water spray mode key, and an alarm control key.

[0017] The working principle of this utility model is as follows:

[0018] The communication interface module of the fire detector connects to the signal acquisition module of the field control box, transmitting the detected signals and image processing information to the field control box. The communication module of the fire extinguishing device connects to the signal acquisition module of the field control box, transmitting information collected by the infrared and ultraviolet sensors of the fire extinguishing device, the positioning information of the horizontal and vertical motors, the status information of the sprinkler valves, the water flow indicator, the signal valve, and the automatic control valve to the field control box. The linkage communication module of multiple field control boxes connects to the multi-channel signal module of the linkage control cabinet, transmitting information from the fire detectors and fire extinguishing devices to the central processing module of the linkage control cabinet. The central processing module works in conjunction with the storage module and the equipment parameter setting module to record the status information of the fire detectors and fire extinguishing devices, and to perform parameter setting operations such as start-up and reset. The field control box can be switched to manual control mode, transmitting data to the field control box via the manual control panel buttons, thereby controlling the action of the fire extinguishing device and achieving manual fire extinguishing on-site.

At the same time, the display screen of the manual control panel displays the image signal of the fire extinguishing device. The fourth is the remote manual fire extinguishing mode. Through the remote operation of the linkage control cabinet, the on-duty staff can manually intervene to operate the fire extinguishing device to extinguish the fire based on the real-time video image of the scene.

[0038] The linkage control cabinet serves as the main control facility. It connects to multiple field control boxes via an RS485 bus. Each field control box acts as an area execution facility, managing fire detectors and fire extinguishing devices in a specific zone. The linkage control cabinet also connects to a manual control panel for emergency intervention.

[0039] The communication interface module of the fire detector connects to the signal acquisition module of the field control box, transmitting the detected signals and image processing information to the field control box. The communication module of the fire extinguishing device connects to the signal acquisition module of the field control box, transmitting information collected by the infrared and ultraviolet sensors of the fire extinguishing device, the positioning information of the horizontal and vertical motors, the status information of the sprinkler valves, and the numerical information of the water flow indicator to the field control box.

At the same time, the linkage control cabinet obtains information collected by the infrared and ultraviolet sensors of the fire extinguishing device, the positioning information of the horizontal and vertical motors, the status information of the sprinkler valves and the numerical information of the water flow indicator through the field control box. The central processing module of the linkage control cabinet performs intelligent calculation and judgment, and gives appropriate relevant parameters and operation instructions for the fire extinguishing device, and mobilizes the fire extinguishing device in the corresponding area to extinguish the fire according to the instructions.
