Description

Technical Field

[0001] This utility model relates to the field of fire protection communication technology, and in particular to an outdoor cabinet electrical fire protection linkage system. Background Technology

[0002] To meet practical application needs, outdoor cabinets are often set up in some scenarios and corresponding electrical equipment is installed. For example, to meet power demand, energy storage cabinets are set up in outdoor scenarios and battery packs and other related energy storage equipment are installed in the energy storage cabinets. The safety of outdoor cabinets is usually ensured through outdoor cabinet electrical fire protection linkage technology.

[0003] Currently, the most common outdoor cabinet electrical fire alarm linkage technology mainly relies on communication between the fire alarm control panel and the main control center (such as the battery management system (BMS) corresponding to the battery pack) to transmit fire alarm signals (such as abnormal or alarm signals). Practice has shown that the existing communication methods of outdoor cabinet electrical fire alarm linkage technology are relatively simple. If the communication line between the fire alarm control panel and the main control center fails, it will result in the inability to transmit fire alarm signals in a timely manner, thus hindering the timely handling of any abnormalities in the outdoor cabinet.

[0031] Compared with the prior art, the embodiments of this utility model have the following beneficial effects:

[0032] In this utility model, the outdoor cabinet electrical fire-fighting linkage system includes a fire control panel and a relay, wherein: the first signal transmission terminal of the fire control panel is electrically connected to the first terminal of the relay; the second signal transmission terminal of the fire control panel is electrically connected to the main control center; and the third terminal of the fire control panel is electrically connected to the power supply.

Furthermore, since the relay is independent of the communication protocol and relies only on the action of physical contacts, the relay can still trigger signal transmission by closing / opening contacts when the fire control panel software fails or the communication protocol is incorrect, achieving hardware-level redundancy. By enhancing the fault isolation of signal transmission, the reliability and stability of information transmission of the fire control panel are further improved. Attached Figure Description

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0039] It should be noted that, unless otherwise expressly specified and limited, the term "electrical connection" in the specification, claims, and accompanying drawings of this utility model should be interpreted broadly. For example, it can be a fixed electrical connection, a detachable electrical connection, or an integral electrical connection; it can be a mechanical electrical connection, an electrical-electrical connection, or a connection that allows for communication; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two elements or an interaction between two elements. Furthermore, the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish different objects, not to describe a specific order. The terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0040] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0041] This utility model discloses an outdoor cabinet electrical fire alarm linkage system. It can transmit fire alarm signals to the main control center simultaneously via a second signal transmission terminal and a first signal transmission terminal (relay) using both a fire alarm control panel and a relay. Even if the direct signal transmission path between the fire alarm control panel and the main control center fails, the relay can still transmit the fire alarm signal to the main control center via hardware contacts. The main control center and the fire alarm control panel can achieve interconnection through multiple paths, avoiding signal loss due to a single communication failure and improving the reliability of information transmission from the fire alarm control panel. Furthermore, since the relay is independent of the communication protocol and relies solely on physical contact action, even if the fire alarm control panel software fails or the communication protocol is incorrect, the relay can still trigger signal transmission by closing / opening its contacts, achieving hardware-level redundancy. By enhancing the fault isolation of signal transmission, the reliability and stability of information transmission from the fire alarm control panel are further improved. Detailed descriptions follow.

[0042] Example 1

[0043] Please see Figure 1 , Figure 1 This is a structural schematic diagram of an outdoor cabinet electrical fire alarm linkage system disclosed in an embodiment of this utility model. Wherein, Figure 1 The described outdoor cabinet electrical fire protection linkage system can be applied to outdoor cabinet fire control panels, fire extinguishing controllers, and other equipment. It can also be used in associated equipment such as battery devices, cloud devices, edge computing devices, smart home devices, sensing devices, relay devices, base station devices, and smart network devices. This utility model embodiment does not limit the scope of the application. Figure 1 As shown, the outdoor cabinet electrical fire alarm linkage system includes a fire alarm control panel 10 and a relay 20, wherein:

[0044] The first signal transmission terminal of the fire alarm control panel 10 is electrically connected to the first terminal of the relay 20; the second signal transmission terminal of the fire alarm control panel 10 is used to electrically connect to the main control center 100; and the third terminal of the fire alarm control panel 10 is used to electrically connect to the power supply 200. The second terminal of the relay 20 is used to electrically connect to the main control center 100 and / or other electrical fire management equipment 300.

[0045] The fire alarm control panel 10 is used to communicate with the main control center 100 through the second signal transmission terminal to transmit the fire alarm signal to be transmitted to the main control center 100; and / or, to communicate with the relay 20 through the first signal transmission terminal to transmit the fire alarm signal to be transmitted to the relay 20.

[0046] Relay 20 is used to communicate with the main control center 100 and / or other electrical fire management equipment 300 to transmit received fire signals to the main control center 100 and / or other electrical fire management equipment 300.

[0047] It should be noted that for each end described in this utility model embodiment, it is not limited to having only one lead wire per end; it may include multiple leads wires, as long as the descriptions are consistent and the logic is not conflicting.

[0048] In this embodiment of the present invention, optionally, the communication method of the second signal transmission terminal can be CAN / RS485 communication, the main control center 100 can be specifically a battery management system (BMS), and other electrical fire protection management equipment 300 includes at least an equipment management system (EMS).

[0049] While sending the fire signal to be transmitted to the BMS (main communication path) through the second signal transmission terminal (CAN / RS485), the fire signal to be transmitted can be sent to the relay simultaneously through the first signal transmission terminal (relay control terminal).

[0050] Alternatively, the relay can act as a redundant signal distributor to ensure multi-path signal transmission. After receiving the fire signal from the fire control panel, it can simultaneously send signals to the BMS and EMS through its contacts (normally open / normally closed).

[0051] Normally open contacts (5 & 9) are used as DI inputs (hardware direct connection paths) of the BMS.

[0052] Normally closed contacts (1 & 9) serve as the DI input (alternate path) for EMS.

[0053] System advantages:

[0054] Triple signal protection: When the main communication (CAN / RS485) fails, the DI input can still transmit signals; when the BMS fails, the EMS can take over the alarm.

[0055] As can be seen, implementing this utility model embodiment enables the fire control panel and relays to simultaneously transmit the fire signal to the main control center via the second signal transmission terminal and the first signal transmission terminal (relay). When the path for direct signal transmission between the fire control panel and the main control center fails, the relay can still transmit the fire signal to the main control center via hardware contacts. The main control center and the fire control panel can achieve interconnection through multiple paths, avoiding signal loss caused by a single communication failure and improving the reliability of information transmission of the fire control panel. Furthermore, since the relay is independent of the communication protocol and relies only on the action of physical contacts, the relay can still trigger signal transmission by closing / opening contacts when the fire control panel software fails or the communication protocol is incorrect, achieving hardware-level redundancy. By enhancing the fault isolation of signal transmission, the reliability and stability of information transmission of the fire control panel are further improved.

[0056] In this embodiment of the utility model, as an optional implementation method, such as Figure 2 As shown, the aforementioned outdoor cabinet electrical fire alarm linkage system also includes a signal converter 30, wherein:

[0057] The first end of the signal converter 30 is electrically connected to the second signal transmission end of the fire control panel 10, and the second end of the signal converter 30 is used to electrically connect to the main control center 100.

[0058] The signal converter 30 is used to communicate with the fire control panel 10 and the main control center 100, so that the signal converter 30 can convert the fire signal provided by the second signal transmission terminal and transmit the converted signal to the main control center 100.

[0059] In this embodiment of the present invention, optionally, the above-mentioned signal converter is a protocol converter, specifically a 232 / 485 converter, connected to the main control center fire protection 485;

[0060] As can be seen, implementing this optional embodiment can convert the fire signal output by the fire control panel into a receiving signal that is compatible with the main control center protocol through a signal converter. In addition to improving the reliability of information transmission between the fire control panel and the main control center, it also provides an interface for accessing a third access point, so as to facilitate the expansion and upgrading of the system and improve the application scenarios of the outdoor cabinet electrical fire linkage system.

[0061] In this embodiment of the present invention, as another optional implementation, the relay 20 mentioned above includes at least a first type of contact for electrically connecting to the main control center 100 and / or a second type of contact for electrically connecting to other electrical fire management equipment 300.

[0062] In this embodiment of the present invention, optionally, the first type of contact described above can be a normally open contact:

[0063] For example, the BMS is connected (it is disconnected by default, and the trigger signal is closed in case of a fire alarm).

[0064] The second type of contact can be a normally closed contact:

[0065] For example, connect to EMS (default closed, disconnected to trigger signal in case of fire).

[0066] To achieve a complementary design, when the normally open contact fails, the normally closed contact can still send a signal to the EMS through a state change (opening); this ensures that if one contact fails, the other contact can still transmit an alarm.

[0067] As can be seen, implementing this optional embodiment can achieve complementary signal protection through the first type of contact (such as normally open): closing during a fire alarm to send a signal to the BMS / station-level fire control panel; and the second type of contact (such as normally closed): opening during a fire alarm to send a signal to the EMS. This ensures that even if the normally open contact fails due to adhesion, the normally closed contact can still trigger an alarm through a state change, providing double protection. At the same time, it can flexibly adapt to devices with different input types (such as high-level / low-level triggering) to optimize device compatibility.

[0068] In this embodiment of the utility model, as another optional implementation method, such as Figure 3 As shown, the aforementioned outdoor cabinet electrical fire alarm linkage system also includes a first communication module 40, wherein:

[0069] The third terminal of relay 20 is electrically connected to the first terminal of the first communication module 40, and the second terminal of the first communication module 40 is electrically connected to the station-level fire alarm control panel 400.

[0070] In this embodiment of the present invention, the first communication module can optionally expand the station-level signal transmission channel and be compatible with station-level fire control panels from different manufacturers. If the fire control panel used in the outdoor cabinet and the station-level fire control panel are from different manufacturers, there may be a communication problem. Therefore, the first communication module is needed to unify the communication method. If the outdoor cabinet and the fire station use the same fire control panel, the first communication module is not needed and the station-level fire control panel can be directly connected to achieve triple communication protection.

[0071] The relay contacts (8 & 12) output signals to the first communication module. The relay contacts (8 & 12) can be normally open contacts. The first communication module converts the signals into a format supported by the station-level fire control panel and transmits them to the station-level fire control panel via wired / wireless transmission. If the station-level control panel is far away, the first communication module can also transmit signals via Ethernet / 4G.

[0072] Alternatively, the first communication module can be embedded in the station-level fire control panel to reduce the space occupancy of the fire control panel. Or, both the fire control panel and the station-level fire control panel may include the first communication module to improve communication efficiency and the accuracy of information transmission. The specific configuration can be determined according to the actual application scenario.

[0073] As can be seen, implementing this optional embodiment can convert relay signals into receiving signals compatible with the station-level fire alarm control panel protocol through the first communication module, solving the problem of incompatibility between protocols of equipment from different manufacturers, eliminating information silos, and allowing the station-level fire alarm control panel to directly receive alarm signals without modifying the existing system. It also helps to solve the signal attenuation problem caused by the long distance between the outdoor cabinet and the station-level control panel, avoids the increase of fault points due to complex wiring, and improves the reliability of long-distance signal transmission.

[0074] In an optional embodiment, such as Figure 4 As shown, the aforementioned outdoor cabinet electrical fire alarm linkage system also includes a multi-dimensional sensing module 50, wherein:

[0075] The multi-dimensional sensing module 50 is electrically connected to the fourth terminal of the fire alarm control panel 10;

[0076] The multi-dimensional sensing module 50 is used to communicate with the fire control panel 10 to provide the sensed environmental signals to the fire control panel 10.

[0077] The fire alarm control panel 10 is also used to generate an environmental anomaly signal as a fire alarm signal to be transmitted when there is an anomaly in the environment monitored by the multi-dimensional sensing module 50.

[0078] In this embodiment of the present invention, the optional multi-dimensional sensing module may include, but is not limited to, temperature sensors (battery compartment / electrical compartment), smoke sensors, etc.

[0079] Execution logic:

[0080] If the temperature / smoke exceeds the standard, the fire alarm control panel will trigger an audible and visual alarm plus a fire alarm signal.

[0081] If the concentration of combustible gas exceeds the standard, the fire alarm control panel will immediately activate the ventilation system (intake / exhaust fans).

[0082] An abnormal environmental signal is generated as a fire alarm signal, which is synchronously transmitted to the BMS / EMS / station-level fire control panel via relays to intervene in flammable gas leaks at an early stage and prevent the risk of explosion.

[0083] As can be seen, implementing this optional embodiment can achieve real-time monitoring of fire anomalies through multi-dimensional sensing modules. For example, real-time monitoring by combustible gas detectors and immediate activation of the ventilation system when the concentration exceeds the standard can expel combustible gases in the early stages of battery cell thermal runaway, preventing the risk of explosion from escalating. Temperature / smoke sensors are linked to cover the entire life cycle of fire monitoring. At the same time, multi-dimensional real-time monitoring based on multi-dimensional sensing modules can also help reduce false alarm rates, improve the comprehensiveness of environmental monitoring, the accuracy of fire anomaly response, and the comprehensiveness of analysis of the outdoor cabinet electrical fire linkage system, reduce the occurrence of situations where fire suppression is triggered only due to temperature rise, and improve the accuracy of fire resource utilization.

[0084] In another alternative embodiment, such as Figure 4 As shown, the aforementioned outdoor cabinet electrical fire alarm linkage system also includes a second communication module 60, wherein:

[0085] The first end of the second communication module 60 is electrically connected to the fourth end of the fire control panel 10, and the second end of the second communication module 60 is used to electrically connect to the first type of fire-fighting equipment 500.

[0086] The second communication module 60 is used to communicate with the fire control panel 10 and with the first type of fire equipment 500 to detect the operating status signal of the first type of fire equipment 500 and transmit the operating status signal to the fire control panel 10.

[0087] The fire control panel 10 is also used to generate an equipment fault signal as a fire signal to be transmitted when the operating status signal indicates that the first type of fire equipment 500 has a fault.

[0088] In this embodiment of the present invention, optionally, the monitoring object of the second communication module can be a combustible gas detector or an intake and exhaust fan (a type of fire-fighting equipment).

[0089] Execution logic:

[0090] Real-time acquisition of equipment status (such as fan current and detector readings).

[0091] Abnormal status (such as fan stoppage, detector failure) → Fire alarm control panel generates equipment fault signal.

[0092] Fault signal transmission path:

[0093] CAN / RS485 → BMS;

[0094] Normally open contacts → EMS, to provide early warning of equipment failure and prevent the fire protection function from being paralyzed.

[0095] As can be seen, implementing this optional embodiment can monitor the status of fire-fighting equipment (such as fan stoppage or detector failure) in real time through the second communication module, synchronously report the fault signal to EMS / BMS, trigger timely maintenance, avoid fire-fighting system paralysis, and reduce the risk of secondary accidents caused by equipment failure, which is conducive to further improving the reliability and stability of information transmission of the fire control panel.

[0096] In this optional embodiment, as an optional implementation method, such as Figure 4 As shown, the aforementioned outdoor cabinet electrical fire alarm linkage system also includes an alarm 70 and / or an emergency start / stop button 80, wherein:

[0097] The alarm 70 is electrically connected to the fourth terminal of the fire alarm control panel 10;

[0098] The emergency start / stop button 80 is electrically connected to the fourth terminal of the fire alarm control panel 10.

[0099] In this embodiment of the present invention, optionally, the alarm device includes an audible and visual alarm device, which is triggered by the fire alarm control panel in case of fire; the emergency start / stop button is used to intervene in the fire extinguishing process (such as emergency stop of ventilation / start of aerosol), and the button signal is directly connected to the fire alarm control panel, covering the automatic logic.

[0100] As can be seen, implementing this optional embodiment can override the automatic logic through the emergency start / stop button, forcibly start or stop the ventilation or fire extinguishing device, so that personnel can quickly intervene according to the on-site situation, prevent the automatic system from malfunctioning, and the audible and visual alarm provides on-site warnings, assists personnel evacuation, and improves the safety of human-machine collaboration.

[0101] In an optional embodiment, such as Figure 4 As shown, the aforementioned outdoor cabinet electrical fire alarm linkage system also includes a second type of fire-fighting equipment 90, wherein:

[0102] The second-class fire-fighting equipment 90 is electrically connected to the fifth terminal of the fire-fighting control panel 10;

[0103] The fire alarm control panel 10 is also used to communicate with the second-class fire-fighting equipment 90 to monitor the operating status signals of the second-class fire-fighting equipment 90 as fire signals to be transmitted; and / or,

[0104] The second type of fire-fighting equipment 90 is used to automatically start and perform abnormal handling operations when an abnormal environment is detected.

[0105] In this embodiment of the present invention, optionally, the second type of fire-fighting equipment mentioned above may include an aerosol fire extinguishing device, whose self-starting logic is that when the temperature sensor detects an ultra-high temperature, the aerosol is automatically released (independent of the fire control panel).

[0106] Its linkage logic is that the fire control panel monitors the aerosol status (such as spraying signals) and reports it to the BMS / EMS through relays. In the event of a complete communication failure, the temperature triggering mechanism ensures the final fire extinguishing guarantee.

[0107] As can be seen, implementing this optional embodiment enables the automatic release of aerosols—a type of fire-fighting equipment—when the temperature exceeds a threshold, independent of the fire control panel, to provide a backup guarantee in extreme situations. This ensures that fire suppression can still be triggered even when all communication fails, preventing the spread of fire, and that the fire control panel can simultaneously monitor the aerosol status to ensure that the actions are traceable.

[0108] In another alternative embodiment, such as Figure 4 As shown, the aforementioned first-class fire-fighting equipment 500 includes a first-class sub-fire-fighting equipment 501 and a second-class sub-fire-fighting equipment 502 that is linked to the first-class sub-fire-fighting equipment 501, wherein:

[0109] The signal terminals of the first type of sub-fire equipment 501 and the second type of sub-fire equipment 502 are electrically connected to the second terminal of the second communication module 60, respectively, and the linkage terminal of the first type of sub-fire equipment 501 is electrically connected to the linkage terminal of the second type of sub-fire equipment 502.

[0110] In this embodiment of the present invention, optionally, the first type of sub-fire protection equipment is a combustible gas detector, and the second type of sub-fire protection equipment is a ventilation system (intake / exhaust fan).

[0111] Linkage logic:

[0112] If the detector detects that the gas concentration exceeds the standard, it will report to the fire control panel through the second communication module. The fire control panel will immediately start the exhaust fan and send a start signal to the EMS through the relay to quickly reduce the concentration of combustible gas and prevent an explosion.

[0113] As can be seen, implementing this optional embodiment can provide a rapid risk suppression mechanism. If the combustible gas exceeds the standard, the exhaust fan will be started immediately (without delayed judgment), which can shorten the response time from the gas concentration exceeding the standard to the execution, and suppress the formation of explosion conditions.
