Description

Technical Field

[0001] The invention relates to the technical field of fire alarm display controllers for ship fire fighting systems, and in particular to a fire alarm display controller linkage fire extinguishing safety control system. Background Art

[0002] In ship fire fighting systems, due to the particularity of the ship's environment, functions and tasks, ship fires are different from land buildings. Ship fire fighting systems have the characteristics of complex structure, dense space, strong heat conduction performance, and many combustible materials. In traditional ship fire fighting systems, the fire alarm display controller has a low degree of intelligence and weak fire extinguishing linkage control capabilities. Although fire detection is still the first line of defense to prevent fire from harming humans, fire fighting is also regarded as an important line of defense to protect property and assets. As we all know, fire fighting is a double-edged sword: water spray fire fighting systems are likely to cause damage to mission-critical computer systems and electronic equipment, gas fire extinguishing agents (such as carbon dioxide, Halon 1301, FM-200, etc.) may cause damage to personnel lives and equipment safety, and even the release of the most inert fire extinguishing agents will cause varying degrees of damage to equipment. The main goal of any fire fighting system is to prevent the release of fire extinguishing agents unless absolutely necessary, and there is no room for error in the release of fire 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 start the fire extinguishing system, it can ensure that the water spray system can be started or the fire extinguishing agent can be released safely and reliably. In other cases, any unnecessary release of fire extinguishing agent needs to be eliminated, which can greatly improve the safety and reliability of the fire alarm display controller's linkage fire extinguishing control.

[0044] The present invention is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the present invention, but are not intended to limit the present invention in any form. It should be noted that, for those of ordinary skill in the art, several changes and improvements can also be made without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0045] Example 1

[0046] A fire alarm display controller linked fire extinguishing safety control system provided according to the present invention can be used to control an automatic water sprinkler fire extinguishing system, the automatic water sprinkler fire extinguishing system includes: a pre-action water sprinkler fire extinguishing system, a rain sprinkler fire extinguishing system and a fine water mist fire extinguishing system, and can also be used to control an automatic gas fire extinguishing system, the automatic gas fire extinguishing system includes: releasing carbon dioxide, halons and other gaseous fire extinguishing agents; it is intended to improve the safety and reliability of the fire alarm display controller linked fire extinguishing control, eliminate any unnecessary release of fire extinguishing agents, and ensure the safety and reliability of necessary releases.

[0047] The fire alarm display controller linkage fire extinguishing safety control system comprises: 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 realizes the scanning and diagnosis of the loop equipment of the fire protection system, and is used to coordinate, process and interpret the information received from and sent to the loop equipment; wherein the loop equipment includes: intelligent detectors, intelligent modules, manual alarm buttons, etc.;

[0049] The CPU module is used to realize the linkage control logic processing of the fire alarm, and communicates with the loop communication control module and the fire extinguishing agent release sequence module using the field bus EtherCat bus, and is used to realize the processing of the fire alarm information, fault information, monitoring information, etc. reported by the loop communication control module to the fire protection system loop, and performs linkage fire extinguishing logic processing according to the protection area where the fire alarm occurs, and sends linkage control instructions to the loop communication control module, and sends an automatic release signal to the fire extinguishing agent release sequence module to start the release of the water spray system or the gas fire extinguishing agent;

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

[0051] The fire extinguishing agent release sequence module has a series of built-in timers for determining the duration of the suspension sequence and the release sequence. The timers are highly accurate and flexibly configurable. Three release sequences are provided, namely, automatic release sequence (configurable delay time), manual release sequence (configurable delay time) and suspension release sequence. All release sequences are subject to the constraints of the configurable timer, which can be configured to communicate directly with the loop communication control module using the loop bus, or with the CPU module using Ethernet. When a fire alarm message is received on the fire alarm loop or a fire alarm message sent by the CPU module, the automatic release sequence can be started. The module can be installed on a fire alarm display controller, or it can be installed on site at low cost through loop bus communication and transmit the installation position of the module relative to other loop devices to the fire alarm display controller.

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

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

The module has multiple built-in safety measures and is equipped with an open circuit and short circuit fault detection circuit for the fire extinguishing agent release control circuit. When an open circuit or short circuit fault is detected in the fire extinguishing agent release circuit, a local fault alarm will be issued and the fault information will be sent to the fire alarm display controller for alarm. The module is also equipped with a fire extinguishing agent release control voltage detection circuit. When the control voltage is insufficient and the fire extinguishing agent cannot be successfully released, the module will issue a local fault alarm for the fault and send the fault information to the fire alarm display controller for alarm.

[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 space size of different fire extinguishing protection areas, 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 redundant control.

[0056] The fire extinguishing agent release control module outputs a fire extinguishing agent release control signal after processing the manual release control signal through the secondary bistable circuit and the drive circuit, thereby realizing safe and stable fire extinguishing agent release control.

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

The 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 subject to configurable timers, which provide the opportunity to manually abort the release. If the abort signal is not received before the timer expires, a determined fire extinguishing agent release signal will be sent to the fire extinguishing agent release control module, which can ensure safe and reliable fire extinguishing agent release while preventing unnecessary fire extinguishing agent release.

[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 way of automatic release control of fire extinguishing agent, and the second MCU circuit and the fourth MCU circuit serve as another way of automatic release control of fire extinguishing agent, and the two ways serve as backup 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 the automatic release control signal, the fire extinguishing agent release control module interprets the signal after receiving the automatic release control signal, and determines the combination of fire extinguishing agent cylinders to be released. The fire extinguishing agent can be successfully released only when the processor MCU1 and the processor MCU3 (or the processor MCU2 and the processor MCU4) output the release control signal at the same time; the fire extinguishing agent release control module also includes an open circuit fault diagnosis circuit, which detects the open circuit and short circuit faults of the fire extinguishing agent release circuit in real time, and performs local fault alarm and reports to the fire alarm display controller for alarm; the fire extinguishing agent release control module also includes a state holding circuit, which can maintain the fire extinguishing agent release state; the fire extinguishing agent release control module also includes a state refresh circuit, which can manually refresh the fire extinguishing agent release state on the fire alarm display controller control panel or the module locally, to ensure that the actual state of the current fire extinguishing agent cylinder empty or full is displayed in real time; the fire extinguishing agent release control module also includes a control voltage detection circuit.

[0067] In a preferred embodiment of the present invention, it is explained that the present invention can realize three fire extinguishing agent release sequences of the fire alarm display controller, with multiple safety measures to ensure safe and reliable fire extinguishing agent release and prevent unnecessary fire extinguishing agent release. Figure 1 As shown, the loop communication control card, CPU module, fire extinguishing agent release sequence control module, and fire extinguishing agent release control module are installed in the fire alarm display controller in a track-type manner, and the modules communicate with each other using the field bus EtherCat bus.

The CPU module performs linkage fire extinguishing logic processing according to the protection zone where the fire occurs, and sends the automatic release signal to the fire extinguishing agent release sequence module. After receiving the automatic release signal, the fire extinguishing agent release sequence will start the fire extinguishing agent automatic release sequence. A manual release button and an abort release button are set on the fire alarm display controller panel. When the manual release button is pressed, the fire extinguishing agent release sequence module will start the manual release sequence; during the execution of the automatic release sequence and the manual release sequence, before the delay timer expires, if the abort release button is pressed, the fire extinguishing agent release sequence module will start the abort release sequence.

[0079] 8) After receiving the manual release signal, the fire extinguishing agent release control module outputs a stable fire extinguishing agent release control signal after processing through the secondary bistable drive circuit.

[0082] 2) Activate a detector on the fire protection system loop, and the loop communication control module receives the fire alarm and reports it to the CPU module;

[0083] 3) The CPU module determines the protection zone where the fire occurs based on the received fire alarm information, and sends the valve opening control command of the corresponding protection zone to the loop communication control module;

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

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

[0086] 6) Activate the acoustic alarm (sounds at a certain pulse frequency, the frequency is configurable);

[0087] 7) Activate the manual delay timer;

[0094] 1) Before the automatic delay timer expires, the release of the fire extinguishing agent will be stopped. The automatic delay timer continues to run, and when the stop button pops up, it will send an automatic release control signal to release the fire extinguishing agent after the automatic delay timer expires or when the stop button pops up;
