Description

Technical Field

[0001] This utility model belongs to the field of automatic fire extinguishing technology and relates to an automatic fire extinguishing system. Background Technology

[0002] In recent years, with the acceleration of urbanization and the expansion of building scale, fire safety hazards have become increasingly prominent. Traditional fire extinguishing systems have certain limitations in terms of fire monitoring, response speed, and extinguishing efficiency. Existing automatic fire extinguishing systems typically rely on a single type of detector (such as smoke detectors or heat detectors) for fire detection, which is prone to false alarms or missed alarms due to environmental interference (such as electromagnetic interference), affecting the reliability of the system. In addition, some systems lack real-time image monitoring capabilities, failing to provide firefighters with intuitive information about the fire scene and delaying fire extinguishing decisions.

[0003] Currently, some fire suppression systems employ simple linkage control methods, relying solely on detectors to trigger alarms or activate fire suppression devices. However, they fail to adequately consider the differentiated fire suppression needs of various fire types (such as electrical fires and liquid fires), resulting in ineffective fire suppression. Furthermore, in the event of power outages or extreme weather conditions (such as lightning strikes), the system's continuous operational capability is insufficient, potentially causing critical functions to fail.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings:

[0027] This utility model provides an automatic fire extinguishing system, such as Figure 1 As shown, the system includes a sensing module, an alarm device, a control center, and a fire extinguishing device. Both the sensing module and the fire extinguishing device are located within the monitoring area. The sensing module includes a camera and at least two detectors of different types. All detectors are connected to the alarm device. A manual fire triggering device is also installed within the monitoring area, and this device is connected to the alarm device. Both the alarm device and the camera are connected to the control center. The control center is connected to the fire extinguishing device.

[0028] This invention integrates a camera and various types of detectors into a sensing module, enabling multi-dimensional real-time monitoring of fire signals. This significantly improves the accuracy and reliability of fire identification and effectively reduces false alarm rates. Secondly, the system employs a linkage mechanism between the alarm device and the control center. When at least two detectors trigger signals (reaching a preset fire detection threshold) or when one detector triggers a signal plus a manual fire trigger, an audible and visual alarm is simultaneously activated, and the alarm signal is transmitted to the control center. This ensures rapid response from on-site personnel and facilitates precise decision-making by the command center. Furthermore, by comprehensively analyzing detector data and camera footage, the control center can intelligently assess the fire situation and automatically activate fire extinguishing devices, achieving rapid and precise fire suppression and minimizing fire losses. This invention features a rational system structure, combining the advantages of automation and manual intervention, significantly improving the efficiency and safety of fire prevention and control.

[0029] This invention optimizes fire detection and extinguishing strategies for the special environment of power plants (such as high-frequency electromagnetic interference, dust accumulation, and humidity). In terms of detection, by combining smoke detectors, heat detectors, flame detectors, or gas detectors (at least two of the same or different types), it overcomes the limitations of single sensors under complex operating conditions and improves the anti-interference capability and environmental adaptability of fire identification, ensuring accurate early detection of fires. The number and location of detectors in each monitoring area must not only meet the requirements of the "Code for Design of Automatic Fire Alarm Systems" (GB50116) but also protect all areas within the monitoring area, leaving no dead zones. In terms of extinguishing, water mist extinguishers, dry powder extinguishers, or gas extinguishers (single or mixed) are flexibly configured according to on-site needs. This not only matches the extinguishing requirements of different areas of the power plant (such as electrical equipment and oil storage areas) but also avoids secondary damage caused by inappropriate media. Through the collaborative design of "multi-dimensional detection + customized extinguishing," the system improves the safety level of the power plant while also considering reliability, economy, and environmental friendliness.

[0030] Secondly, the distance between adjacent detectors does not exceed 10m, ensuring that a fire in any location can be detected simultaneously by at least two detectors. This achieves dual verification to avoid false alarms and precise location of the fire source through multi-point positioning. In key areas such as cable trenches and transformers, this density configuration ensures reliable detection before the flame height reaches 30cm, buying crucial time for early fire suppression.

[0031] Furthermore, this invention further enhances the efficiency and safety of fire emergency response by linking the alarm device with a broadcasting system. When the alarm device detects a fire, it not only triggers an audible and visual alarm but also automatically broadcasts fire information through the broadcasting system, ensuring that on-site personnel (especially those in noisy environments) clearly receive alarm instructions. Simultaneously, the broadcasting system can release real-time evacuation guidance, fire extinguishing prompts, and other voice information, preventing panic and significantly improving the orderliness of personnel evacuation. In addition, it supports remote control centers to conduct manual command via broadcast, forming a multi-level early warning system of "automatic alarm + intelligent broadcasting + manual intervention," which is particularly suitable for collaborative emergency management in large and complex locations such as power plants.

[0032] For example, this invention significantly improves the system's response speed and reliability by adding a controller that directly links the detectors and fire extinguishing devices. When the detector's monitored data (such as smoke concentration, temperature, or flame signals) reaches the fire detection threshold (a single sensor continuously triggering a signal for more than 15 seconds or at least three sensors triggering signals), the controller can bypass the intermediate links of the traditional control center and directly trigger the fire extinguishing device, achieving millisecond-level rapid fire suppression. This is particularly suitable for locations such as power plants where initial fire control requirements are stringent. It avoids response delays caused by network transmission latency or central server failures and forms a "first line of defense" before remote commands from the control center arrive, effectively suppressing the spread of fire.

[0033] The sensing module, alarm device, control center, and controller are all connected to an uninterruptible power supply (UPS). In the event of a sudden power outage or power fluctuation at the power plant, the UPS ensures the continuous and stable operation of critical components such as fire monitoring, alarm, decision-making, and firefighting execution, completely avoiding system paralysis caused by power interruptions. It is particularly suitable for power plant environments with high electromagnetic interference; the UPS's filtering function can also effectively suppress grid noise interference with precision detection equipment. Even in extreme situations, the system can maintain complete fire prevention and control functions, buying valuable time for personnel evacuation and firefighting, truly achieving 24 / 7 uninterrupted safety protection.

[0034] The monitoring area includes indoor and outdoor areas. For outdoor areas, the detectors are equipped with lightning protection devices, which effectively solves the problem of lightning interference in open-air environments and ensures stable and reliable detection signals. For indoor areas, a smoke exhaust device linked to the control center is added. The smoke exhaust device can be started manually or through the control center. It can quickly exhaust dense smoke in the early stages of a fire, which not only improves visibility to facilitate personnel evacuation, but also reduces the interference of smoke on the detectors.

[0035] A lighting component is installed next to the camera to ensure that the camera can still acquire clear images of the fire at night or in low-visibility environments with smoke, thereby improving the environmental adaptability and image recognition accuracy of the fire monitoring system.

[0036] This utility model adopts a "multi-source sensing + intelligent decision-making + hierarchical response" architecture, integrating cameras and multiple types of detectors (smoke, heat, flame, and gas) to form a redundant monitoring network. A dual verification mechanism (dual detector triggering or single detector + manual triggering) reduces the false alarm rate. Combined with image recognition and data analysis, it achieves accurate fire situation determination. A broadcast system enables coordinated audible and visual alarms and voice guidance. Combined with environmentally adaptable designs such as lightning protection, smoke extraction devices, and low-light cameras, it forms an all-weather protection system covering both indoor and outdoor scenarios. Specifically designed for complex operating conditions in power plants, such as high-frequency electromagnetic interference and dusty, humid environments, it achieves accurate fire source detection through detector density optimization, redundant monitoring of key areas, and anti-interference power supply design. This balances early fire suppression timeliness with secondary disaster prevention, achieving a unity of reliable safety protection, economy, and environmental friendliness.

[0037] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
