Description

Technical Field

[0001] This invention relates to the field of fire emergency lights, and in particular to a voice intercom fire emergency light system. Background Technology

[0002] Fire emergency lights are an important component of a building's fire evacuation system. In emergencies such as fires, when the mains power supply may be interrupted, the fire emergency light system operates independently through its built-in backup power supply to provide necessary lighting and evacuation guidance for people inside the building, ensuring that people can quickly and safely evacuate to a safe area.

[0003] In existing technologies, fire emergency lights primarily guide personnel evacuation through directional indication. Specifically, emergency lights located at key points such as evacuation routes, stairwells, and safety exits are equipped with directional indicator lights or displays, which use arrows, text, or flashing signals to indicate the preset evacuation direction to personnel.

[0004] However, in actual fire evacuation, the fire situation is often in a state of flux—the direction of smoke spread may change, new ignition points may appear, and some evacuation routes may become impassable. In such situations, those already on a certain route can immediately detect the danger ahead, but they cannot transmit this crucial real-time information to those behind who have not yet reached that route. Lacking immediate awareness of the changing fire situation, those behind can only continue following the directional signs, potentially being led into areas that have become dangerous, seriously threatening their lives.

[0005] To address these issues, we propose a voice-intercom-based fire emergency lighting system. Summary of the Invention

[0006] The purpose of this invention is to provide a voice intercom fire emergency lighting system to solve the problem mentioned in the background art that when a fire occurs, the personnel at the front cannot transmit real-time information to the personnel at the rear in a timely manner.

[0007] To achieve the above objectives, the present invention provides the following technical solution: A voice intercom fire emergency light system includes an emergency indicator light, equipped with a controller and a detection unit; an emergency module communicatively connected to the controller; a mobile intercom module detachably connected to the emergency indicator light, enabling voice communication between the mobile intercom module and the emergency module; and a separation component disposed on the emergency indicator light for separating the emergency indicator light and the mobile intercom module. When the detection unit detects a fire, the controller controls the emergency indicator light to indicate the escape direction and controls the emergency module to emit a first audio prompt. When an escaping person responds to the first audio prompt and triggers the emergency module, the controller detects the triggering operation, controls the separation component to separate the mobile intercom module from the emergency indicator light, and simultaneously controls the emergency module to emit a second audio prompt. When the mobile intercom module is removed, the second audio prompt stops.

[0008] In a further embodiment, the mobile intercom module and the emergency indicator light are connected magnetically.

[0009] In a further embodiment, the emergency indicator light contains a main battery, and the intercom module contains a secondary battery; when the intercom module is connected to the emergency indicator light, the main battery charges the secondary battery.

[0010] In a further embodiment, the separation component includes a mounting base and a telescopic drive component, the telescopic drive component being disposed on the mounting base and having a telescopic shaft; when the controller controls the telescopic shaft of the telescopic drive component to retract, the mobile intercom module and the emergency indicator light are connected; when the controller controls the telescopic shaft of the telescopic drive component to extend, the telescopic shaft pushes the mobile intercom module, thereby separating the mobile intercom module and the emergency indicator light.

[0011] In a further embodiment, a flexible connector is also included, one end of which is connected to the emergency indicator light and the other end of which is connected to the mobile intercom module; the emergency indicator light is provided with a groove for accommodating the mobile intercom module, and the flexible connector is accommodated in the groove when the mobile intercom module is connected to the emergency indicator light.

[0012] In a further embodiment, after the separation component performs the separation action, the mobile intercom module is suspended above the emergency module via the flexible connector.

[0013] In a further embodiment, a tension sensor is also included, which is used to detect the tension applied to the flexible connector; when the tension sensor detects a tension signal, the controller controls the second audio prompt to stop.

[0014] In a further embodiment, the emergency module includes a housing, a trigger button disposed within the housing, and a protective cover covering the trigger button, the protective cover being detachably connected to the housing.

[0015] In a further embodiment, the mobile intercom module is provided with a first button and a second button; when the first button is triggered, the mobile intercom module sends a forward signal to the controller through the emergency module, and the controller controls the emergency indicator light to maintain the indicated direction; when the second button is triggered, the mobile intercom module sends a danger signal to the controller through the emergency module, and the controller controls the emergency indicator light to display a no-passage indication.

[0016] In a further embodiment, the emergency module is also equipped with a laser emitter, which, when the controller receives the danger signal, controls the laser emitter to emit a visible beam of light on the road.

[0017] Compared with existing technologies, the beneficial effects of this invention are as follows: When the detection unit detects a fire, it sends a fire signal to the controller. Upon receiving the fire signal, the controller controls the emergency indicator light to indicate the escape direction and simultaneously controls the emergency module to issue a first audio prompt. The first audio prompt conveys the message "A voice communication device is available" to the evacuees. When the evacuees respond to the first audio prompt and trigger the emergency module, the controller immediately controls the separation component to separate the mobile intercom module from the emergency indicator light, and simultaneously controls the emergency module to issue a second audio prompt. The second audio prompt guides the evacuees to retrieve the separated mobile intercom module. Once the evacuees retrieve the mobile intercom module, the second audio prompt stops. The evacuees who retrieve the mobile intercom module are the advance personnel. The advance personnel carry the mobile intercom module with them during the evacuation process, and can use the mobile intercom module to communicate with the emergency module via voice.

[0018] At this point, those escaping from the section of road where the emergency indicator light is located will be able to hear the voices of those who went ahead through the speaker on the emergency module when they reach the light. After the advance personnel inform them of the dangers ahead, those behind will adjust their evacuation direction accordingly to avoid the danger zone. Attached Figure Description

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figures 1-3 This application discloses an embodiment of a voice intercom fire emergency light system, which includes an emergency indicator light 1, an emergency module 2, a mobile intercom module 3, and a separation component 4. The emergency indicator light 1 is used to indicate the escape direction in the event of a fire. The emergency module 2 is communicatively connected to the controller 11. The mobile intercom module 3 is detachably connected to the emergency indicator light 1. The separation component 4 is disposed on the emergency indicator light 1 to separate the mobile intercom module 3 from the emergency indicator light 1.

[0025] Specifically, refer to Figure 3 The emergency indicator light 1 is equipped with a controller 11 and a detection unit 12. The detection unit 12 is used to detect the occurrence of a fire and send a fire signal to the controller 11. The controller 11, as the control core of the system, receives the signal from the detection unit 12, controls the indication status of the emergency indicator light 1, and coordinates the actions of the emergency module 2 and the separation component 4. In some embodiments, the controller 11 can be a microcontroller, an ARM processor, or a PLC programmable controller. The emergency indicator light 1 adopts a fire emergency sign light fixture, and its surface is provided with markings indicating the escape direction.

[0026] Emergency module 2 is used for voice interaction with escaping personnel. Emergency module 2 is communicatively connected to emergency indicator light 1, and the two exchange data via wired or wireless means. In some embodiments, emergency module 2 is communicatively connected to the controller 11 of emergency indicator light 1 via an RS485 bus; in other embodiments, emergency module 2 can also communicate with controller 11 via Bluetooth. Emergency module 2 is equipped with a speaker and a microphone; the speaker is used to play audio prompts, and the microphone is used to collect the voice of escaping personnel.

[0027] The mobile intercom module 3 is detachably connected to the emergency indicator light 1. Under normal conditions, the mobile intercom module 3 is mounted on the emergency indicator light 1; in the event of a fire, the mobile intercom module 3 can be detached from the emergency indicator light 1 for evacuees to take. The mobile intercom module 3 is equipped with a wireless communication unit, enabling voice communication with the emergency module 2. In some embodiments, the wireless communication unit is a DECT module or a Wi-Fi module. The mobile intercom module 3 is equipped with a speaker and a microphone, allowing evacuees to conduct two-way voice communication with the emergency module 2 after taking the mobile intercom module 3.

[0028] The separation component 4 is located on the emergency indicator light 1 and is used to separate the mobile intercom module 3 from the emergency indicator light 1 under the control of the controller 11. The separation component 4 receives the instruction from the controller 11 and performs the separation action, causing the mobile intercom module 3 to detach from the emergency indicator light 1, so that it can be used by the escaped personnel.

[0029] The following describes the workflow of this system in the event of a fire.

[0030] When the detection unit 12 detects a fire, it sends a fire signal to the controller 11. Upon receiving the fire signal, the controller 11 controls the emergency indicator light 1 to indicate the escape direction and simultaneously controls the emergency module 2 to issue a first audio prompt. The first audio prompt conveys the message that "a voice communication device is available" to the escaping personnel, for example, by playing a voice message such as "Please press the button to access the intercom device." The purpose of the first audio prompt is to guide the escaping personnel to actively trigger the system and initiate the separation process between the mobile intercom module 3 and the emergency indicator light 1.

[0031] When an evacuee responds to the first audio prompt and triggers the emergency module 2—for example, by pressing the trigger button 22 on the emergency module 2—the controller 11 detects the triggering operation. The controller 11 then controls the separation component 4 to perform a separation action, separating the mobile intercom module 3 from the emergency indicator light 1, and simultaneously controls the emergency module 2 to emit a second audio prompt. The second audio prompt guides the evacuee to retrieve the separated mobile intercom module 3, for example, by playing a voice message saying "Please retrieve the intercom device."

[0032] The second audio prompt stops after the evacuee removes the mobile intercom module 3. The evacuee who removes the mobile intercom module 3 is considered the advance evacuee. The advance evacuee carries the mobile intercom module 3 with them during the evacuation. If the advance evacuee discovers a hazard ahead—such as a change in the direction of smoke spread, the appearance of a new fire source, or a blocked passage—the advance evacuee can communicate with the emergency module 2 via the mobile intercom module 3. The advance evacuee's voice is collected by the mobile intercom module 3, transmitted to the emergency module 2 via the wireless communication unit, and played back by the speaker of the emergency module 2.

[0033] At this time, those escaping from the section of road where emergency indicator light 1 is located, upon reaching it, will be able to hear the voices of those who went ahead through the speaker of emergency module 2. After the first group informs them of the dangers ahead, those behind will adjust their evacuation direction accordingly, avoiding the danger zone.

[0034] In addition to the above, in this embodiment, the separation and removal of the mobile intercom module 3 and the cessation of the audio prompt form a coherent action chain. During the entire process, the escaped personnel only need to complete two actions: "pressing the button and removing the module". No additional confirmation or waiting steps are required, which greatly reduces the difficulty of operation for escaped personnel in the fire scene.

[0035] In some implementations, the mobile intercom module 3 and the emergency indicator light 1 are connected magnetically. Specifically, refer to... Figure 1 , Figure 4 An iron plate 13 is installed on the emergency indicator light 1, and a permanent magnet is installed at the corresponding position of the iron plate 13 on the mobile intercom module 3. Under normal conditions, the mobile intercom module 3 is magnetically attracted to the emergency indicator light 1. When separation is required, the controller 11 controls the separation component 4 to overcome the magnetic attraction and push the mobile intercom module 3 apart. By employing a magnetic connection, the mobile intercom module 3 can be securely held on the emergency indicator light 1 under normal use and will not fall off due to building vibration or accidental contact. When separation is required, the magnetic connection eliminates the need for mechanical latches; the separation component 4 can directly overcome the magnetic attraction to complete the separation, resulting in a faster response.

[0036] As an alternative to magnetic connection, in some embodiments, the intercom module 3 and the emergency indicator light 1 can also be connected by a snap-fit ​​connection or a flexible clamp connection. In a snap-fit ​​connection, the snap-fit ​​is disengaged by the separation component 4; in a flexible clamp connection, the intercom module 3 is clamped by the deformation of an elastic element, and when disengaged, the intercom module 3 is pushed by the separation component 4 to overcome the elastic force and detach from the clamp.

[0037] In some implementations, the emergency indicator light 1 houses a main battery, and the intercom module 3 houses a secondary battery. Both the main and secondary batteries are rechargeable batteries, such as lithium-ion or nickel-metal hydride batteries. When the intercom module 3 is connected to the emergency indicator light 1, the main battery charges the secondary battery. Specifically, refer to... Figure 1 , Figure 4 The emergency indicator light 1 is equipped with a conductive sheet 14, and the mobile intercom module 3 has a charging contact 31 at the corresponding position of the conductive sheet 14. When the mobile intercom module 3 is connected to the emergency indicator light 1, the charging contact 31 on the mobile intercom module 3 contacts the conductive sheet 14, and the main battery charges the auxiliary battery through the charging circuit. With this configuration, the mobile intercom module 3 is always fully charged by the main battery in normal standby mode. In the event of a fire, after the mobile intercom module 3 is removed, it relies on the auxiliary battery for power, ensuring that the mobile intercom module 3 can continue to conduct voice communication even after being disconnected from the emergency indicator light 1. At the same time, after the mains power is cut off in the event of a fire, the main battery is powered by the fire emergency power supply, eliminating the need for a separate charging line for the mobile intercom module 3 and simplifying the building's fire protection electrical design.

[0038] In some implementations, refer to Figure 1 , Figure 4 The separation component 4 includes a mounting base 41 and a telescopic drive component 42. The mounting base 41 is fixedly disposed inside or on the surface of the emergency indicator light 1, and the telescopic drive component 42 is disposed on the mounting base 41. The telescopic drive component 42 has a telescopic shaft. When the controller 11 controls the telescopic shaft of the telescopic drive component 42 to retract, the end of the telescopic shaft does not push against the mobile intercom module 3, and the mobile intercom module 3 and the emergency indicator light 1 remain connected. When the controller 11 controls the telescopic shaft of the telescopic drive component 42 to extend, the end of the telescopic shaft pushes against the mobile intercom module 3, overcoming magnetic attraction or locking force, and separating the mobile intercom module 3 and the emergency indicator light 1.

[0039] Regarding the specific form of the telescopic drive component 42, in a preferred embodiment, the telescopic drive component 42 is an electromagnetic push rod. The electromagnetic push rod contains an electromagnetic coil and a moving iron core. When energized, the electromagnetic coil generates a magnetic field that pushes the moving iron core outward; when de-energized, a spring resets, causing the moving iron core to retract. The electromagnetic push rod has a fast response speed, typically completing the extension action within tens of milliseconds, suitable for the time-sensitive requirements in fire scenarios. In other embodiments, the telescopic drive component 42 can also be a motor-driven screw mechanism. The motor drives the screw to rotate via gears or couplings, and the nut on the screw moves axially, connecting to the telescopic shaft to achieve extension and retraction. The thrust of the motor-driven screw mechanism is greater than that of the electromagnetic push rod, suitable for scenarios with strong magnetic attraction or tight clamping. In still other embodiments, the telescopic drive component 42 can also be a pneumatic push rod, using compressed gas to push a piston to extend the telescopic shaft, suitable for scenarios where there is already a compressed air pipeline network within the building.

[0040] When the telescopic shaft extends and pushes the mobile intercom module 3, the direction of the pushing force is consistent with the separation direction of the mobile intercom module 3, which reduces the lateral torque during the separation process, making the separation action smoother and preventing the mobile intercom module 3 from getting stuck during separation.

[0041] Normally, the emergency indicator light 1 is hung on the wall. When the intercom module 3 and the emergency indicator light 1 separate, without any measures, the intercom module 3 will fall directly downwards under gravity, possibly hitting the ground and causing damage. Therefore, refer to... Figure 1 , Figure 5The system also includes a flexible connector 5, one end of which is connected to the emergency indicator light 1, and the other end to the mobile intercom module 3. The emergency indicator light 1 has a groove for accommodating the mobile intercom module 3, and the flexible connector 5 is housed within this groove when the mobile intercom module 3 is connected to the emergency indicator light 1. This design ensures that the mobile intercom module 3 is completely embedded in the groove during normal standby mode, with the flexible connector 5 hidden inside and not exposed to the outside of the emergency indicator light 1. This maintains the clean appearance of the emergency indicator light 1 and prevents the flexible connector 5 from being accidentally pulled or hooked during normal operation. When the mobile intercom module 3 is separated from the emergency indicator light 1, the connection provided by the flexible connector 5 prevents the mobile intercom module 3 from falling directly to the ground, thus providing effective protection for the mobile intercom module 3.

[0042] Regarding the specific form of the flexible connector 5, in a preferred embodiment, the flexible connector 5 is a thin wire. When the mobile intercom module 3 detaches from the emergency indicator light 1 and descends to its lowest point, the thin wire can pull on the mobile intercom module 3, preventing it from falling to the ground. When escapees need to remove the mobile intercom module 3, they pull on it; the thin wire is not strong enough to withstand the pulling force and thus breaks, allowing the escapees to remove the mobile intercom module 3. In other embodiments, the flexible connector 5 can also be in other forms, as long as it can achieve the same function as the thin wire.

[0043] After the separation component 4 performs the separation action, the mobile intercom module 3 is suspended above the emergency module 2 via the flexible connector 5. Specifically, the connection point of the flexible connector 5 is located in the upper area of ​​the emergency indicator light 1. When the mobile intercom module 3 is pushed apart, it naturally hangs down under gravity, suspended below the emergency indicator light 1. Since the emergency module 2 is installed below the emergency indicator light 1, for example, on the wall below the emergency indicator light 1, the suspended mobile intercom module 3 is positioned directly above the emergency module 2, within easy reach of escapees. This design prevents the mobile intercom module 3 from falling to the ground after separation, avoiding the problem of escapees having difficulty finding it in dense smoke environments. Simultaneously, being suspended above the emergency module 2 places the mobile intercom module 3 in a conspicuous position between the emergency indicator light 1 and the emergency module 2, allowing escapees to directly see and retrieve the mobile intercom module 3 after operating the emergency module 2, reducing search time.

[0044] In some implementations, refer to Figure 3The system also includes a tension sensor 6, which detects the pulling force on the flexible connector 5. The tension sensor 6 can be installed inside the emergency indicator light 1 near the fixed end of the flexible connector 5. When an escapee removes the mobile intercom module 3, it will inevitably pull on the flexible connector 5. After detecting this pulling signal, the sensor sends a signal to the controller 11, which then stops the second audio prompt. It should be noted that the tension sensor 6 requires a certain threshold to trigger. After the mobile intercom module 3 separates from the emergency indicator light 1, when the mobile intercom module 3 falls to its lowest point, it will also exert a pulling force on the thin wire, but this force is insufficient to trigger the tension sensor 6.

[0045] In some implementations, refer to Figure 1 , Figure 6 Emergency module 2 includes a housing 21, a trigger button 22 housed within the housing 21, and a protective cover 23 covering the trigger button 22. The protective cover 23 is detachably connected to the housing 21. Under normal conditions, the protective cover 23 covers the trigger button 22 to prevent accidental activation. In the event of a fire, evacuees must remove the protective cover 23 before pressing the trigger button 22. This design ensures that people in the building, such as cleaning staff and children, will not accidentally trigger the system even if they touch emergency module 2, thus avoiding false alarms and wasting system resources. Furthermore, the act of removing the protective cover 23 itself constitutes a conscious confirmation action—evacuees clearly know they are activating the fire intercom system, rather than touching it unintentionally.

[0046] Regarding the detachable connection method of the protective cover 23, for example, the protective cover 23 is connected to the housing 21 by a fragile plastic connection, and the escapee can disconnect the connection between the protective cover 23 and the housing 21 by forcefully pulling it. Alternatively, the protective cover 23 is connected to the housing 21 by a hinge, and the escapee can flip the protective cover 23 outward to expose the trigger button 22.

[0047] In some embodiments, the mobile intercom module 3 is equipped with a first button 32 and a second button 33. The first button 32 and the second button 33 are used to send different signals. When the first button 32 is triggered, the mobile intercom module 3 sends a forward signal to the controller 11, and the controller 11 controls the emergency indicator light 1 to maintain the indicated direction. When the second button 33 is triggered, the mobile intercom module 3 sends a danger signal to the controller 11, and the controller 11 controls the emergency indicator light 1 to display a "no passage" indication. The "no passage" indication may be, for example, a red "×" sign, or the forward direction indicator may be turned off. In some embodiments, the first button 32 may be equipped with a "√" sign, and the second button 33 may be equipped with an "×" sign, making it easier for the person moving forward to perform the correct operation.

[0048] With this setup, during evacuation using the mobile intercom module 3, if evacuees find the passage ahead safe, they can press the first button 32. The system will maintain the current direction of instruction, allowing subsequent evacuees to continue evacuating in that direction. If they find the passage ahead dangerous, such as excessive smoke, a blocked passage, or a spreading fire, they can press the second button 33. The system will immediately mark the passage as impassable. Subsequent evacuees, seeing the impassable sign displayed on the emergency indicator light 1, will change their evacuation direction to avoid accidentally entering a dangerous area. In this way, the first evacuees can use the two buttons on the mobile intercom module 3 to report the actual situation of the passage ahead to the system. The system then dynamically adjusts the escape guidance accordingly, forming an information transmission chain from "evacuees to the system and then to subsequent evacuees," thus improving overall evacuation efficiency.

[0049] It should be noted that the communication path for the mobile intercom module 3 to send signals to the controller 11 varies. In one embodiment, the mobile intercom module 3 communicates directly with the emergency module 2 through its built-in wireless communication unit, and the emergency module 2 then transmits the signal to the controller 11. In another embodiment, the mobile intercom module 3 communicates directly with the controller 11 through its built-in wireless communication unit, without going through the emergency module 2.

[0050] In some implementations, the emergency module 2 is also equipped with a laser emitter. The laser emitter is electrically or communicatively connected to the controller 11. When the controller 11 receives a danger signal, i.e., the signal that the second button 33 is triggered, the controller 11 controls the laser emitter to emit a visible beam of light in the passageway. The visible beam forms a visible light path in the smoke, stretching across the passageway, providing a strong visual warning to those escaping.

[0051] Regarding the specific form of the laser emitter, in a preferred embodiment, the laser emitter is a green laser diode. Green laser has good scattering characteristics in smoke, high visibility, and green has high sensitivity in human vision. In other embodiments, the laser emitter may also be a red laser diode. Red is usually associated with the meaning of "danger" and "stop," making it easier for escaping personnel to understand its warning meaning.

[0052] The laser emitter emits a visible beam laterally, creating a horizontal line of light in the passageway, positioned near the eye level of the escaping personnel. As escaping personnel move along the passageway, if the passageway ahead is marked as dangerous, the visible beam emitted by the laser emitter will form a clear horizontal line in the smoke. Upon seeing this, escaping personnel can immediately determine that the path ahead is impassable without needing to approach to see the markings on Emergency Indicator 1, making it particularly effective in dense smoke environments.

[0053] It should also be noted that the laser emitter emitting a visible beam and the controller 11 controlling the emergency indicator light 1 to display an "impassable" indication can occur simultaneously. Both provide multiple perspectives of "impassable" warning from different locations: the emergency module 2 and the emergency indicator light 1. The emergency indicator light 1 provides visual indication through its own changing markings, while the laser emitter provides supplementary warning through its beam. In situations with high smoke concentrations and where the emergency indicator light 1 is difficult to see, the scattering of the laser beam in the smoke makes the warning information more easily perceived by those escaping.

[0054] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0055] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
