Description

Technical Field

[0001] This invention relates to the field of fire alarm display controller technology for ship fire protection systems, and more specifically, to a fire alarm display controller-linked fire extinguishing safety control system. Background Technology

[0002] In shipboard firefighting systems, the unique environment, function, and mission of ships lead to fires that differ from those on land. Shipboard firefighting systems are characterized by complex structures, dense spaces, strong heat conduction, and a large amount of combustible materials. Traditional shipboard firefighting systems often have low levels of intelligence in their fire alarm display controllers and weak fire suppression linkage control capabilities. While fire detection remains the first line of defense against fire hazards, fire suppression is also considered a crucial line of defense for protecting property and assets. It is well known that fire suppression is a double-edged sword: water spray systems can potentially damage critical mission computer systems and electronic equipment; gaseous extinguishing agents (such as carbon dioxide, Halon 1301, FM-200, etc.) can harm personnel and equipment safety; and even the release of the most inert extinguishing agents can cause varying degrees of damage to equipment. The primary objective of any fire suppression system is to prevent the release of extinguishing agents unless absolutely necessary; there is no room for error in the release of extinguishing agents. Therefore, it is necessary to design a powerful linkage fire extinguishing safety control system for the fire alarm display controller. When it is absolutely necessary to activate the fire extinguishing system, it should ensure the safe and reliable activation of the sprinkler system or release of the extinguishing agent. In other cases, it should eliminate any unnecessary release of the extinguishing agent. This can greatly improve the safety and reliability of the linkage fire extinguishing control of the fire alarm display controller.

[0043] Figure 3 A schematic diagram of the extinguishing agent release control module is shown. Detailed Implementation

[0044] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0045] Example 1

[0046] The present invention provides a fire alarm display controller-linked fire extinguishing safety control system, which can be used to control an automatic sprinkler system, including a pre-action sprinkler system, a deluge sprinkler system, and a fine water mist system. It can also be used to control an automatic gas extinguishing system, which includes the release of gaseous extinguishing agents such as carbon dioxide and halon. The aim is to improve the safety and reliability of the fire alarm display controller-linked fire extinguishing control, eliminate any unnecessary release of extinguishing agents, and ensure the safety and reliability of any necessary releases.

[0047] The fire alarm display controller is linked to the fire extinguishing safety control system, including: a loop communication control module, a CPU module, a fire extinguishing agent release sequence module, and a fire extinguishing agent release control module.

[0048] The loop communication control module enables the scanning and diagnosis of loop devices in the fire protection system, and is used to coordinate, process, and interpret information received from and sent to loop devices; wherein, loop devices include: intelligent detectors, intelligent modules, manual alarm buttons, etc.

[0049] The CPU module is used to implement the linkage control logic processing of fire alarms. It communicates with the loop communication control module and the extinguishing agent release sequence module via the EtherCat fieldbus. It is used to process fire alarm information, fault information, monitoring information, etc. reported by the loop communication control module to the fire protection system loop, perform linkage extinguishing logic processing according to the protected area where the fire alarm occurs, send linkage control commands to the loop communication control module, and send an automatic release signal to the extinguishing agent release sequence module to start the sprinkler system or release the gas extinguishing agent.

[0050] The extinguishing agent release sequence module is used to configure the extinguishing agent release sequence and has multiple safety measures to ensure safe and reliable extinguishing agent release while preventing unnecessary extinguishing agent release.

[0051] The extinguishing agent release sequence module incorporates a series of timers to determine the duration of the abort and release sequences. These timers are highly accurate and flexibly configurable. Three release sequences are provided: automatic release sequence (configurable delay time), manual release sequence (configurable delay time), and abort release sequence. All release sequences are constrained by the configurable timers. The extinguishing agent release sequence module is an addressable module that can communicate directly with the loop communication control module via a loop-2 bus, or with the CPU module via Ethernet. Upon receiving a fire alarm message from the fire alarm loop or from the CPU module, the automatic release sequence can be initiated. This module can be installed on the fire alarm display controller, or it can be installed in the field at low cost via loop bus communication and transmit its installation location relative to other loop devices to the fire alarm display controller.

[0052] The extinguishing agent release sequence module supports two independent release circuits. The release circuits are used to provide automatic release control and manual release control to the extinguishing agent release module. One of the two release circuits can be configured as the release control of the gaseous extinguishing agent, and the other can be configured as the release control of the water sprinkler system.

[0053] The extinguishing agent release sequence module can be used to control automatic sprinkler systems (pre-action sprinkler systems, deluge sprinkler systems, and fine water mist systems), and can also be used in automatic gas extinguishing systems (releasing gaseous extinguishing agents such as carbon dioxide and halon).

[0054] The extinguishing agent release control module is used to ensure the safe release of the extinguishing agent. The module incorporates multiple safety measures, including an open-circuit and short-circuit fault detection circuit for the extinguishing agent release control line. When an open-circuit or short-circuit fault is detected in the extinguishing agent release line, a local fault alarm will be triggered, and the fault information will be sent to the fire alarm display controller for alarm activation. The module also includes an extinguishing agent release control voltage detection circuit. If the control voltage is insufficient, the extinguishing agent may fail to release successfully; in this case, the module will trigger a local fault alarm and send the fault information to the fire alarm display controller for alarm activation.

[0055] After receiving the automatic release control signal, the fire extinguishing agent release control module interprets the signal and determines the combination of fire extinguishing agent cylinders to be released (the required fire extinguishing agent volume is determined according to the size of the space of different fire protection zones, thereby determining the combination of fire extinguishing agent cylinders to be controlled). In order to improve the safety of fire extinguishing agent release, the module adopts a dual-processor (MCU) symmetrical circuit to achieve safety and redundancy control.

[0056] The extinguishing agent release control module processes the manual release control signal through a two-stage bistable circuit and a drive circuit, and then outputs the extinguishing agent release control signal to achieve safe and stable extinguishing agent release control.

[0057] The extinguishing agent release control module is equipped with a status holding circuit to maintain the extinguishing agent release status; it is also equipped with a status refresh circuit, which allows the extinguishing agent release status to be manually refreshed on the fire alarm display controller control panel or locally on the module, ensuring that the actual status of the current extinguishing agent cylinder being empty or full is displayed in real time.

[0058] Example 2

[0059] Example 2 is a preferred example of Example 1.

[0060] like Figure 1 As shown in the figure, this embodiment provides a fire alarm display controller linked to fire extinguishing safety control system, including: a loop communication control module, a CPU module, a fire extinguishing agent release sequence module, a fire extinguishing agent release control module, and a fire alarm display controller control panel.

[0061] The loop communication control module enables the scanning and diagnosis of loop devices (intelligent detectors, intelligent modules, manual alarm buttons, etc.) in the fire protection system, and is used to coordinate, process, and interpret information received from and sent to the loop devices.

[0062] The CPU module is used to process fire alarm information reported by the loop communication control module to the fire protection system loop, perform linkage fire extinguishing logic processing according to the protected area where the fire alarm occurred, send linkage control commands to the loop communication control module, and send an automatic release signal to the fire extinguishing agent release sequence module to start the release of the sprinkler system or gaseous fire extinguishing agent.

[0063] The extinguishing agent release sequence module is used to configure the extinguishing agent release sequence and has multiple safety measures to ensure safe and reliable extinguishing agent release while preventing unnecessary extinguishing agent release.

[0064] like Figure 2 As shown, the extinguishing agent release sequence module provided in this embodiment includes: an Ethernet communication circuit for Ethernet communication with the CPU module; an MCU circuit for configuring the release sequence; a timer circuit for providing a high-precision, flexibly configurable timer to determine the duration of the abort sequence and the release sequence; a pre-release circuit for activating audible and visual alarms at the start of the release sequence to remind personnel to prepare and evacuate; a release circuit for providing automatic and manual release control to the extinguishing agent release module, supporting two independent release circuits; and a loop bus communication line for implementing loop bus communication.

[0065] The extinguishing agent release sequence module incorporates a series of timers to determine the duration of the abort and release sequences. These timers are highly accurate and flexibly configurable. Three release sequences are provided: automatic release sequence (configurable delay time), manual release sequence (configurable delay time), and abort release sequence. All release sequences are constrained by configurable timers, which provide the opportunity for manual abort of release. If no abort signal is received before the timer expires, a definitive extinguishing agent release signal is sent to the extinguishing agent release control module, ensuring safe and reliable extinguishing agent release while preventing unnecessary releases.

[0066] like Figure 3 As shown, the fire extinguishing agent release control module provided in this embodiment includes: an Ethernet communication circuit and a dual-processor symmetrical circuit; the first MCU circuit and the third MCU circuit of the dual-processor symmetrical circuit serve as one automatic fire extinguishing agent release control, and the second MCU circuit and the fourth MCU circuit serve as another automatic fire extinguishing agent release control, with the two circuits serving as backups for each other; that is, when the third MCU circuit and / or the first MCU circuit fails, the second MCU circuit and the fourth MCU circuit are used; when the fire extinguishing agent release sequence module successfully outputs an automatic release control signal, the fire extinguishing agent release control module receives the automatic release control signal, interprets the signal, and determines the combination of fire extinguishing agent cylinders to be released. The extinguishing agent can only be successfully released when processors MCU1 and MCU3 (or MCU2 and MCU4) simultaneously output release control signals. The extinguishing agent release control module also includes an open-circuit fault diagnosis circuit to detect open and short circuit faults in the extinguishing agent release line in real time, and to issue local fault alarms and report them to the fire alarm display controller. The module also includes a status holding circuit to maintain the extinguishing agent release status. Furthermore, it includes a status refresh circuit, which allows manual refreshing of the extinguishing agent release status on the fire alarm display controller control panel or locally within the module, ensuring real-time display of the actual empty / full status of the extinguishing agent cylinder. The module also includes a control voltage detection circuit; if the control voltage is insufficient, the extinguishing agent will fail to release successfully, and the module will issue a local fault alarm and send the fault information to the fire alarm display controller. Finally, the module includes a two-stage bistable drive circuit, employing a bistable circuit with a stable output state. This circuit can remain stable under specific input conditions, is not easily disturbed, and can achieve safe and stable extinguishing agent release control.

[0067] In a preferred embodiment of the present invention, it is illustrated that the present invention can realize three extinguishing agent release sequences of the fire alarm display controller, with multiple safety measures to ensure safe and reliable extinguishing agent release while preventing unnecessary extinguishing agent release. For example... Figure 1 As shown, the loop communication control card, CPU module, and extinguishing agent release sequence control module are mounted on a rail inside the fire alarm display controller. The modules communicate with each other via an EtherCat fieldbus. The loop communication control module communicates with the loop devices installed in each protected area via a loop-two bus, sending fire alarm information from the protected area to the CPU module. The CPU module performs linkage extinguishing logic processing based on the protected area where the fire alarm occurred and sends an automatic release signal to the extinguishing agent release sequence module. Upon receiving the automatic release signal, the extinguishing agent release sequence module initiates its automatic release sequence. A manual release button and a stop release button are provided on the fire alarm display controller panel. Pressing the manual release button initiates the manual release sequence. If the stop release button is pressed before the delay timer expires during the execution of the automatic or manual release sequences, the extinguishing agent release sequence module initiates the stop release sequence. The third type of release sequence is described below:

[0068] a) Normal operating status:

[0069] 1) Under normal operating conditions, the extinguishing agent release sequence module monitors the open circuit and short circuit faults of the release circuit and pre-release circuit. If any circuit is open or short-circuited, the module will issue a fault indication and report the fault information to the fire alarm display controller for fault alarm and display, and to the extinguishing agent release control module.

[0070] 2) The extinguishing agent release control module detects open circuit and short circuit faults in the extinguishing agent release line in real time, and issues local fault alarms and reports them to the fire alarm display controller. When the control voltage is insufficient, the extinguishing agent will fail to be released successfully. The module will issue a local fault alarm for this fault and send the fault information to the fire alarm display controller.

[0071] b) Manually release the sequence:

[0072] 1) Manually release the sequence delay timer and set it to 25 seconds;

[0073] 2) Press the manual release button on the fire alarm display controller;

[0074] 3) After receiving a manual release signal, the extinguishing agent release sequence module will disable the automatic release sequence and the abort release sequence, and start the manual release sequence;

[0075] 4) Activate the manual delay timer and activate the audible alarm (it sounds at a certain pulse frequency, which can be configured);

[0076] 5) The light alarm will be activated 2 seconds after the delay timer starts;

[0077] 6) Ten seconds before the delay timer expires, the audible alarm will change to a steady ringing sound;

[0078] 7) After the delay timer expires, the release circuit is activated and sends a manual release control signal to the extinguishing agent release control module;

[0079] 8) After receiving the manual release signal, the extinguishing agent release control module processes the signal through a two-stage bistable drive circuit and outputs a stable extinguishing agent release control signal.

[0080] c) Manually release the sequence:

[0081] 1) Set the automatic release sequence delay timer to 25 seconds;

[0082] 2) Activate a detector on the fire protection system circuit. After receiving the fire alarm, the circuit communication control module reports it to the CPU module.

[0083] 3) The CPU module determines the protected area where the fire occurred based on the received fire alarm information and sends the corresponding valve opening control command to the loop communication control module.

[0084] 4) After the valve opens, the CPU module sends an automatic release signal to the extinguishing agent release sequence module.

[0085] 5) After receiving the automatic release signal, the extinguishing agent release sequence module starts the automatic release sequence;

[0086] 6) Activate the audible alarm (sounds at a specific pulse frequency, which is configurable);

[0087] 7) Activate the manual delay timer;

[0088] 8) The light alarm will be activated 2 seconds after the delay timer starts;

[0089] 9) Ten seconds before the delay timer expires, the audible alarm will change to a steady ringing sound;

[0090] 10) After the delay timer expires, the release circuit is activated and sends the automatic release control signal to the extinguishing agent release control module;

[0091] 11) After receiving the automatic release signal, the extinguishing agent release control module outputs a stable extinguishing agent release control signal through a dual-processor symmetrical circuit.

[0092] d) Abort the release sequence:

[0093] During the automatic release sequence, if the release stop button is pressed on the fire alarm display controller, the extinguishing agent release sequence module will start the stop sequence, which can be configured as one of the following four stop modes;

[0094] 1) The release of the extinguishing agent will be stopped before the automatic delay timer expires. The automatic delay timer continues to run, and when the stop button is released, an automatic release control signal will be issued to release the extinguishing agent after the automatic delay timer expires or when the stop button is released.

[0095] 2) The release of the extinguishing agent will be stopped before the automatic delay timer expires. The automatic delay timer stops running, and after the stop button is released, the automatic delay timer will resume running from the stop point, and will release the extinguishing agent upon the automatic delay timer expiring by issuing an automatic release control signal.

[0096] 3) The release of the extinguishing agent will be stopped before the automatic delay timer expires. The automatic delay timer stops running, and after the stop button is released, the automatic delay timer resets and restarts timing. When the automatic delay timer expires, an automatic release control signal is sent to release the extinguishing agent.

[0097] 4) The release of extinguishing agent will be stopped before the automatic delay timer expires. The automatic delay timer will stop running, and will reset and stop running after the stop button is released.
