Description

Technical Field

[0001] This utility model relates to the field of fire extinguishing control, and in particular to a zoned intelligent fire extinguishing control system for ships and the ship itself. Background Technology

[0002] Existing ship fire suppression technologies all employ a single, integrated fire suppression system. Upon detecting a fire within the vessel, this system directly controls the entire ship into fire suppression mode, even activating fire suppression devices in different locations. However, due to the large size of ships and the varying properties of their different areas, when one area catches fire, other areas may not necessarily require fire suppression preparations. Furthermore, if a fire starts at the bow, the fire suppression devices at the stern may not need to be activated or controlled. Existing fire suppression systems with automatic sprinkler systems cannot achieve centralized control; while distributed control systems cannot accurately and reliably control fire suppression in different areas across the ship's overall structure. This lack of reliable control over the ship leaves safety hazards remaining in terms of fire suppression control.

[0003] Existing fire control methods generally employ fire extinguishing devices deployed at different locations on the ship. Common fire extinguishing devices include carbon dioxide fire extinguishing devices and fine water mist fire extinguishing devices. For example, patent application number 202022781580.6 discloses a backpack-type fine water mist fire extinguishing device for ships, relating to the field of ship fire extinguishing technology. It discloses a device including a water storage bottle, a gas storage bottle, a spray gun, a backpack frame, and a mounting frame. The backpack frame includes an arc-shaped skeleton, with a mounting plate fixed to the rear bottom of the arc-shaped skeleton. A first positioning sleeve and a second positioning sleeve are fixed between the arc-shaped skeleton and the mounting plate via a connecting frame. Both the first and second positioning sleeves have fixing caps fixed to their top ends.

[0004] Existing fire extinguishing devices installed on ships are not specifically designed for this purpose and do not take into account independent control or coordinated control of different zones within the ship, thus failing to achieve accurate and reliable fire extinguishing. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a shipboard zoned intelligent fire suppression control system and ship. Through zoned control, it can achieve effective and accurate zoned fire suppression and coordinated fire suppression. It can effectively and accurately control fire suppression and achieve coordinated control to prevent the spread of fire.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a shipboard zoned intelligent fire extinguishing control system, which divides the ship into multiple zones, and each zone is equipped with a fire extinguishing device, a monitoring sensor, and a slave control unit; within each fire extinguishing zone: the monitoring sensor is connected to the slave control unit, and the output of the slave control unit is connected to the fire extinguishing device; the slave control unit is connected to the main control unit via wired or wireless means, and the output of the main control unit is connected to an alarm display unit.

[0007] The control units in adjacent areas are connected via wired or wireless means.

[0008] The control system also includes an interlocking unit, through which the slave control unit in the current area is connected to the fire extinguishing device in the adjacent area. When the fire extinguishing device in the current area is triggered, the interlocking unit interlocks and triggers the fire extinguishing device in the adjacent area.

[0009] The interlocking unit includes an interlocking contact switch, the control terminal of which is set in the control circuit between the slave control unit and the fire extinguishing device in the current area; the interlocking contact switch is set in the control enable circuit of the fire extinguishing device in the adjacent area.

[0010] The fire extinguishing device includes a carbon dioxide fire extinguishing device and a fine water mist fire extinguishing device. The output terminal of the control unit is connected to the control terminal of the carbon dioxide fire extinguishing device and the fine water mist fire extinguishing device respectively to drive them to work.

[0011] A human detection sensor is installed in each designated area. The human detection sensor is used to detect human signals in its area. Its output is connected to the slave control unit of the area. The slave control unit controls the working status of the carbon dioxide fire extinguishing device based on the human signals.

[0012] Each area has a control unit connected to an alarm, which is used to issue a fire alarm signal.

[0013] Each area's control unit is connected to a timer. After detecting a human signal, the timer delays the signal. Once the delay reaches a set time threshold, the control unit outputs a control enable signal to the carbon dioxide fire extinguishing device in the area.

[0014] A vessel comprising the aforementioned fire suppression control system.

[0015] The advantages of this invention are: it achieves effective and accurate zoned fire suppression and coordinated fire suppression through zoned control, which can effectively and accurately control fire suppression and achieve coordinated control to prevent the spread of fire. Attached Figure Description

[0016] The following is a brief explanation of the contents of each of the accompanying drawings and the markings in the drawings:

[0017] Figure 1 This is a schematic diagram of the control system of a fire extinguishing zone in the fire extinguishing system of this utility model. Detailed Implementation

[0018] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and the description of the preferred embodiments.

[0019] This embodiment provides a zoned intelligent automated fire suppression system to meet the fire safety requirements of ships. It achieves intelligent fire control while minimizing the spread of fire and reducing the workload of fire suppression equipment. The specific solution is as follows:

[0020] like Figure 1 As shown, a shipboard zoned intelligent fire suppression control system divides the ship into multiple fire suppression zones. The division can be made according to the actual ship conditions, and different fire suppression devices can be set up according to the zone. For example, the fire suppression devices include two types: carbon dioxide fire suppression devices and fine water mist fire suppression devices. In areas where fire is likely to occur and safety is not critical, both types of fire suppression devices can be set up, while in areas where fire is unlikely to occur, only one type can be set up. Of course, when setting up one type, the choice between carbon dioxide fire suppression devices and fine water mist fire suppression devices can be made according to the number of people in the area. If there are many people or frequent traffic, fine water mist fire suppression devices should be set up; otherwise, carbon dioxide fire suppression devices can be set up.

[0021] After dividing the ship into multiple firefighting zones, each zone is equipped with fire extinguishing devices, monitoring sensors, and a slave control unit. The monitoring sensors, including smoke sensors and flame sensors, are used to monitor and identify fires in their respective zones. The fire extinguishing devices, such as carbon dioxide extinguishing devices and fine water mist extinguishing devices, are controlled by the slave control unit and operate based on its control signals. The slave control unit is the core of the control system and is implemented using a microcontroller with data processing and control capabilities. Considering cost, a lower-cost 51 series or STM32 series microcontroller is used.

[0022] In each fire suppression zone: monitoring sensors are connected to the control unit, and the output of the control unit is connected to the fire suppression device to monitor the fire and control the operation of the fire suppression device.

[0023] The ship's monitoring room houses a main control unit and an alarm display unit. The main control unit interacts with each slave control unit and can be implemented using a microcontroller. It can reuse the same hardware chips as the slave control units or utilize controllers within the monitoring room, such as the monitoring room server or the ship's main controller, to save costs. The alarm display unit includes an alarm and a touchscreen. The alarm sounds a fire, and the touchscreen displays fire information and allows operators in the monitoring room to input control signals. Each slave control unit in a fire suppression zone is connected to the main control unit via wired or wireless means. The output of the main control unit is connected to the alarm display unit. The main control unit uses received fire signals to control the alarm display unit to issue alarm information for monitoring purposes. Monitoring personnel can also actively control the activation and deactivation of fire suppression devices via the touchscreen of the alarm display unit, and can manually activate the fire suppression devices in case of sensor malfunctions or missed detections.

[0024] The working principle of the aforementioned fire suppression system is as follows: Each fire suppression zone is independent, and each zone independently monitors the fire situation within its own area. Monitoring sensors within each zone monitor the fire situation and send the data to a slave control unit. The slave control unit processes the data and uploads it to the main control unit via wired or wireless means for alarm activation. The main control unit then triggers an alarm signal from the alarm display unit in the monitoring room based on the uploaded signal. Simultaneously, slave controllers within each fire suppression zone can activate the fire suppression devices in their respective zones based on the monitored fire situation, thereby facilitating fire suppression.

[0025] In a preferred embodiment, the slave control units in adjacent fire suppression zones are connected by wired or wireless means, so that when communication with the main control unit is interrupted, fire information can be reported to the monitoring room through the slave control units in adjacent fire suppression zones.

[0026] In another preferred embodiment of this application, the fire extinguishing system is equipped with several interlocking units to control the current area and adjacent areas. The control unit in the current area is connected to the fire extinguishing device in the adjacent area via the interlocking unit. When the fire extinguishing device in the current area is triggered, the interlocking unit interlocks the triggering of the fire extinguishing device in the adjacent area. This ensures that after a fire occurs in the current area, the activation of the fire extinguishing device can be interlocked with the activation of adjacent fire extinguishing devices, thereby preventing the spread and expansion of the fire and enabling more effective and reliable fire suppression. Furthermore, to meet cost-saving requirements, interlocking units are not installed in all areas of the ship; they can be installed according to needs. For example, if there is a high probability of fire spread between two adjacent areas, then an interlocking unit is required; otherwise, it is not necessary. The interlocking system is designed to mitigate the risk of rapid fire spread in certain areas of the ship.

[0027] The interlocking unit includes an interlocking contact switch. The control terminal of the interlocking contact switch is located in the control circuit between the slave control unit and the fire extinguishing device in the current area; the interlocking contact switch is located in the control enable circuit of the fire extinguishing device in the adjacent area. Interlocking can be mechanical or electrical. This solution uses electrical interlocking because the slave control unit outputs a control signal to control the fire extinguishing device in its area. This control signal can be used for interlocking. For example, a relay can be used. The output control signal from the slave control unit in this area is routed to the relay's line weight to control its operation. The normally open or normally closed contact of the relay is located at the enable terminal of the fire extinguishing device in the adjacent area. This enables the relay to connect to a trigger signal source, allowing the relay to control the operation of the fire extinguishing device in this area while simultaneously interlocking the fire extinguishing devices in the adjacent area, preventing further fire spread.

[0028] In this embodiment, the fire extinguishing device includes a carbon dioxide fire extinguishing device and a fine water mist fire extinguishing device, which can be selected according to actual needs or both. The output terminal of the control unit is connected to the control terminal of the carbon dioxide fire extinguishing device and the fine water mist fire extinguishing device respectively to drive their operation.

[0029] In areas equipped with carbon dioxide and water mist fire extinguishing systems, a human detection sensor is installed. This sensor detects human signals in the area, and its output connects to the corresponding slave control unit. The slave control unit then controls the operation of the carbon dioxide fire extinguishing system based on the human signals. Each slave control unit is also connected to an alarm system, which issues a fire alert signal.

[0030] Each area's control unit is connected to a timer. After detecting a human signal, the timer delays the signal. Once the delay reaches a set time threshold, the control unit outputs a control enable signal to the carbon dioxide fire extinguishing device in the area.

[0031] Upon detecting a fire signal, the system activates the fine water mist extinguishing device. Simultaneously, it checks for the presence of people in the area. If no one is present, the carbon dioxide extinguishing device is activated directly. If someone is present, an alarm is sounded with a delay before the carbon dioxide extinguishing device is activated. This prevents excessive carbon dioxide from hindering the escape of people in the area. In short, after a fire breaks out, water mist is used to control the fire. If no one is nearby, the carbon dioxide extinguishing device is activated. If someone is present, an alarm is sounded to alert them to leave, and then the carbon dioxide extinguishing device is activated after a delay of several seconds. This ensures the rapid control and extinguishing of the fire while prioritizing the escape of people.

[0032] This embodiment also provides a ship that includes the fire extinguishing control system described above, possessing all the advantages of the fire extinguishing control system described above.

[0033] This invention provides a novel shipboard zoned intelligent fire suppression system. The system integrates advanced zoned fire suppression design, intelligent detection and alarm mechanisms, and efficient operation control mechanisms, aiming to improve the ship's ability to respond to fires and its fire suppression efficiency, thereby ensuring ship safety.

[0034] The components include:

[0035] The control unit is responsible for receiving and processing signals from each detection unit, and controlling the activation and deactivation of each fire extinguishing device. It employs a high-performance microprocessor, possessing powerful data processing and real-time control capabilities.

[0036] Monitoring and sensing units: Distributed in key areas of the ship, these units are responsible for detecting fire signals. They include smoke detectors and temperature sensors, and are capable of detecting fire signals in real time and transmitting them to the central control unit.

[0037] Alarm display unit: Located in the ship's bridge, chief engineer's office, and central control room, it is used to display alarm information. It features a high-brightness LED display screen and audible alarm function, capable of clearly displaying fire information and issuing an alarm.

[0038] Fire extinguishing equipment includes carbon dioxide extinguishing systems and fine water mist extinguishing systems, which are flexibly deployed according to the characteristics of the ship's areas. Carbon dioxide extinguishing systems are used in non-densely populated areas, while fine water mist extinguishing systems are used in densely populated areas to ensure fire extinguishing effectiveness and personnel safety.

[0039] The system divides the ship into multiple fire suppression zones, each equipped with independent fire suppression devices and control units. When a fire occurs in a zone, the central control unit determines the fire location based on signals from the detection units and activates the corresponding zone's fire suppression devices. This zoned fire suppression design significantly improves fire suppression efficiency and reduces the impact on other zones. The system utilizes real-time analysis of data from the detection units to accurately assess the fire situation. Upon detecting a fire signal, the system immediately activates the alarm display unit, issuing audible and visual alarms and displaying the fire location information. Simultaneously, the main control unit sends fire alarm information to relevant personnel so they can take swift action.

[0040] The system includes a manual control module in its monitoring setup. In automatic control mode, the control unit in each area automatically activates and deactivates the fire extinguishing devices based on signals from the detection unit. In manual control mode, operators can manually activate and deactivate the fire extinguishing devices via the control console.

[0041] This novel shipboard zoned intelligent fire suppression system has been practically applied on multiple vessels, achieving significant results. In numerous fire simulation tests, the system was able to quickly and accurately detect fire signals and activate fire suppression devices. Simultaneously, the system exhibits excellent stability and reliability, capable of operating normally in harsh environments. The novel shipboard zoned intelligent fire suppression system provided by this invention possesses significant advantages such as zoned fire suppression, intelligent detection and alarm, and efficient operation control, significantly improving the ship's fire response capabilities and fire suppression efficiency. With the continuous development of the shipbuilding industry and the increasing demands for safety performance, this fire suppression system has broad application prospects and market potential. In the future, we will continue to optimize and improve the system's performance to provide more reliable protection for ship safety.

[0042] Obviously, the specific implementation of this invention is not limited to the above-described methods. Any non-substantial improvements made using the inventive concept and technical solution of this invention are within the protection scope of this invention.
