Description

TECHNICAL FIELD

[0002] The fire emergency lighting controller is a key device in the building fire safety system, and is widely used in the double-run stairway, evacuation passage, safety exit and other areas of residential buildings, commercial buildings, public venues and the like. The core function thereof is to provide necessary light support for personnel evacuation in the event of power interruption, fire and the like, to ensure the visibility of the evacuation path, and to reduce the safety risks such as stampede and getting lost.

[0003] In the prior art, the structure of the fire emergency lighting controller usually comprises a box body (or carrier) mounted on the wall, the box body being integrated with a main control module, a power monitoring module, a fire signal receiving module and a backup power supply (such as a storage battery), and the box body being externally provided with a lighting assembly. The lighting assembly is usually 1-2 LED lighting lamps, which are usually fixedly installed on the top of the box body and are distributed side by side or symmetrically.

[0004] However, in the actual application of the double-run stairway, the platform of the double-run stairway is usually connected with the uplink channel and the downlink channel which are distributed at 90° (the uplink channel steps are gradually raised, and the downlink channel steps are gradually lowered), and the controller is usually fixedly installed on the platform wall at a distance of 1.5-2 meters from the ground, and the position and angle of the lighting assembly are always fixed (such as pointing to the center of the platform side by side).

[0005] When a fire occurs, smoke (especially high-temperature smoke) will form a diffuse air layer in the stairway, which will strongly scatter light; and the light of the fixed lighting can only cover a local area of the platform, and cannot extend to the uplink and downlink channels, resulting in the existence of lighting blind areas in the uplink and downlink channels, which seriously hinders the visual judgment of the steps when personnel escape.

DETAILED DESCRIPTION

[0038] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described, obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all the other embodiments obtained by a person of ordinary skill in the art without creative work belong to the protection scope of the present application.

[0039] Please refer to Figures 1 to 8 An intelligent fire emergency lighting controller comprises a carrier 1 installed on the wall surface of a double-run stair platform, a main control module, a mains monitoring module and a fire signal receiving module are integrated in the carrier 1, and the mains monitoring module and the fire signal receiving module are electrically connected with the main control module. The main control module takes a microprocessor (MCU) as a core, is responsible for receiving external trigger signals (fire alarm signals, mains interruption signals), executing preset control logic (judging emergency starting conditions), sending control instructions (turning on and off lamps, switching modes) and the like; the mains monitoring module monitors the power supply state through a voltage / current sensor, and triggers an emergency mode when the mains is abnormal; the fire signal receiving module receives fire linkage signals through dry contacts or an RS485 interface, and serves as a core trigger condition for starting fire lighting.

[0040] In order to solve the problem that the position of the lighting assembly is fixed in the prior art, resulting in insufficient coverage of the uplink and downlink channels of the double-run stair, the following design is made:

[0041] Symmetrical mounting grooves 5 are arranged on both sides of the carrier 1 and used for assembling core components. The upper end of each mounting groove 5 is in an open state, providing space for the rotation of internal components. A rotating shaft 6 is rotatably connected in each mounting groove 5, and each rotating shaft 6 extends along the thickness direction of the carrier 1. A support column 7 is fixed on each rotating shaft 6, and the axis of each support column 7 is perpendicular to the axis of the rotating shaft 6. A rotating mechanism 8 is arranged in each mounting groove 5 to enable the support column 7 to rotate along the rotating shaft 6, so that the support column 7 can be switched between a vertical state (extending along the height direction of the carrier 1) and a horizontal state (extending along the length direction of the carrier 1) to adapt to different scene requirements.

[0042] A fixed frame 9 is fixed on the end of each support column 7 away from the rotating shaft 6, a turnover shaft 2 is rotatably connected on each fixed frame 9, and each turnover shaft 2 is coaxially arranged with the corresponding support column 7. A lighting lamp 11 is fixed on each turnover shaft 2, and a tilting mechanism 10 is arranged on each fixed frame 9 to enable the lighting lamp 11 to rotate along the turnover shaft 2, and is used for adjusting the irradiation angle of the lighting lamp 11.

[0043] In a daily state, each support column 7 extends vertically along the height direction of the carrier 1, and the two lighting lamps 11 are located at the top of the carrier 1, thereby meeting the basic lighting requirements in daily life and when the mains is interrupted.

[0044] In the fire state, each support column 7 extends horizontally along the length direction of the carrier 1, and two illuminating lamps 11 are respectively located on both sides of the carrier 1 and correspond to the uplink channel and downlink channel of the double-run staircase one by one, and the illuminating lamp 11 opposite to the uplink channel is inclined upward, and the illuminating lamp 11 opposite to the downlink channel is inclined downward.

[0045] With the above design, the working process and effect of the controller are as follows:

[0046] When the mains monitoring module detects power interruption or abnormality through the voltage / current sensor, a trigger signal is immediately transmitted to the main control module; after receiving the signal, the main control module quickly starts the emergency lighting mode. At this time, the two illuminating lamps 11 are located at the top of the carrier 1, accurately covering the staircase platform area, meeting the basic lighting needs of temporary stay or short-distance movement of personnel.

[0047] When the fire signal receiving module receives the fire linkage signal of the fire alarm system through the dry contact or RS485 interface, the signal is synchronously fed back to the main control module; the main control module immediately triggers the fire emergency mode, and synchronously starts the rotating mechanism 8 and the tilting mechanism 12: the rotating mechanism 8 drives the support column 7 to rotate 90° around the rotating shaft 6, switching from the vertical state to the horizontal state, so that the two illuminating lamps 11 are respectively rotated out to both sides of the carrier 1, accurately aligning the uplink channel and downlink channel of the double-run staircase; at the same time, the tilting mechanism 12 drives the corresponding illuminating lamp 11 to tilt according to the channel direction, and the illuminating lamp 11 opposite to the uplink channel is inclined upward to match the steps that are gradually raised; the illuminating lamp 11 opposite to the downlink channel is inclined downward to match the steps that are gradually lowered, forming a directional light beam that is completely adapted to the channel direction.

[0048] The design realizes the dual adjustment of "position switching (from the top of the platform to both sides of the channel) + angle adaptation (precise inclination along the step direction)", so that the lighting range extends from a single platform to both sides of the channel, completely eliminating the lighting blind area in the deep channel. Moreover, through directional inclination, the light is focused on the step surface, reducing the invalid scattering to the wall surface and ground. In a smoke environment, the light penetration is improved by more than 60%, significantly shortening the judgment time of the evacuation path of personnel, and effectively reducing the risk of tripping, stepping and other escape risks.

[0049] The rotating mechanism 8 is introduced as follows:

[0050] The rotating mechanism 8 includes torsion springs 801 sleeved on both ends of the rotating shaft 6, one torsion arm of each torsion spring 801 is connected with the support column 7, and the other torsion arm of each torsion spring 801 is connected with the carrier 1; in the natural state, the torsion spring 801 extends the support column 7 horizontally along the length direction of the carrier 1.

[0051] The rotating mechanism 8 further comprises a permanent magnet 802 fixed to the side wall of the support column 7, and an electromagnet 803 fixed in the mounting groove 5 and matched with the permanent magnet 802, and the electromagnet 803 is electrically connected with the main control module to form an electromagnetic driving loop.

[0052] When the electromagnet 803 is powered (daily state or power interruption state), the magnetic attraction between the electromagnet 803 and the permanent magnet 802 overcomes the elastic force of the torsion spring 801, so that the support column 7 extends vertically along the height direction of the carrier 1, and the two illuminating lamps 11 are close to the top of the carrier 1 to realize the basic illumination of the platform area.

[0053] When the fire signal is triggered, the main control module immediately cuts off the power supply of the electromagnet 803, the magnetic attraction force disappears, and the elastic force of the torsion spring 801 is quickly reset to drive the support column 7 to rotate to the horizontal state quickly, ensuring that the illuminating lamps 11 complete the position switching from the top of the platform to the two sides of the passage within 1 second, which saves valuable time for fire emergency lighting.

[0054] The rotating mechanism 8 adopts a collaborative design of "elastic reset + electromagnetic control", without complex transmission components, which can ensure the reliable positioning of the support column 7 in two states, and can realize millisecond state switching in emergency situations such as fire, which meets the core needs of the fire-fighting equipment "fast response and high reliability".

[0055] Further, the permanent magnet 802 is embedded in the side wall of the support column 7, and the electromagnet 803 is embedded in the mounting groove 5, avoiding the occupation of the internal space of the mounting groove 5 by the protruding components, so that there is no structural interference when the support column 7 rotates, and the horizontal / vertical state switching is smooth.

[0056] In the embodiment, it is necessary to supplement that the rotating shaft 6 is hollow inside, and the support column 7 is hollow inside and communicates with the rotating shaft 6, which not only provides space for the installation of components of the tilting mechanism 10, but also facilitates the wiring (connecting the illuminating lamps 11 and the main control module), making the overall structure more compact.

[0057] The tilting mechanism 10 will be introduced as follows:

[0058] The tilting mechanism 10 comprises a first bevel gear 101 fixed to the end of the rotating shaft 2 and located in the support column 7. A fixed shaft 102 is fixed in the mounting groove 5 and located in the rotating shaft 6 and coaxially arranged with the rotating shaft 6. A second bevel gear 103 is fixed on the fixed shaft 102 and located in the support column 7 and engaged with the first bevel gear 101.

[0059] Specifically, the tooth number ratio of the first bevel gear 101 to the second bevel gear 103 is 3:1-4.5:1. When the support column 7 rotates 90° around the rotation shaft 6 from the vertical state (daily position) to the horizontal state (fire position), the first bevel gear 101 revolves 90° synchronously with the support column 7, and due to the meshing with the fixed second bevel gear 103, a corresponding rotation motion is generated. According to the bevel gear transmission relationship:

[0060] The first bevel gear rotation angle θ1= (the second bevel gear tooth number Z2 / the first bevel gear tooth number Z1) x revolution angle θ2 (90°);

[0061] When the tooth number ratio is 3:1 (Z1:Z2=3:1), θ1= (1 / 3) x 90°=30°;

[0062] When the tooth number ratio is 4.5:1 (Z1:Z2=4.5:1), θ1= (1 / 4.5) x 90°=20°.

[0063] Therefore, the turning angle of the lighting lamp 11 with the turning shaft 10 is 20°-30°, which is exactly suitable for the step inclination requirement of the up-and-down passage of the double-running stairs: the lighting lamp of the up passage is turned up 20°-30°, which can cover the steps that are raised step by step; the lighting lamp of the down passage is turned down 20°-30°, which can focus on the steps that are lowered step by step, avoiding direct or scattered light.

[0064] With the above design, when the fire signal triggers the rotation mechanism 8 to act, the support column 7 rotates (revolves 90°) around the rotation shaft 6 from the vertical state to the horizontal state:

[0065] In this process, the support column 7 drives the first bevel gear 101 to revolve synchronously around the second bevel gear 103 on the fixed shaft 102; since the second bevel gear 103 is fixed, the meshing of the two forces the first bevel gear 101 to rotate (rotation angle 20°-30°); the rotation of the first bevel gear 101 is transmitted to the lighting lamp 11 through the turning shaft 10, so that the lighting lamp 11 completes the angle turning synchronously with the horizontal rotation of the support column 7. Finally, the lighting lamps 11 located on both sides of the carrier 1 are respectively inclined up / down 20°-30°, which accurately matches the step trend of the up-and-down passage.

[0066] This design uses the revolving kinetic energy of the support column 7 to synchronously drive the angle adjustment of the lighting lamp 11, without the need for additional motors or driving components, which not only simplifies the structure, but also ensures the linkage of position switching and angle adjustment (response time ≤1 second), so that the lighting mode switching can be quickly completed in the case of fire emergency, thereby improving the evacuation safety.

[0067] In addition, it is necessary to supplement that in the double stairway scene, the two support columns 7 are symmetrically distributed on both sides of the carrier 1 (corresponding to the uplink and downlink channels), when the fire signal triggers the rotating mechanism 8, the left support column 7 needs to be rotated out to the left horizontal direction (away from the center of the carrier 1), and the vertical state is converted to horizontal extension, and is aligned with the left uplink channel. The right support column 7 needs to be rotated out to the right horizontal direction (also away from the center of the carrier 1), and the vertical state is converted to horizontal extension, and is aligned with the right downlink channel.

[0068] If the meshing positions of the two second bevel gears 103 relative to the first bevel gear 101 are completely the same (such as being located on the same side of the first bevel gear), the rotation directions of the first bevel gear 101 will be completely consistent, resulting in the same flipping direction of the two illuminating lamps 11 (either both upward or both downward), which cannot adapt to the differentiated needs of the uplink and downlink channels.

[0069] Therefore, the reverse flipping needs to be realized through the position differentiation design of the second bevel gear 103 (such as shown in the figure): Figures 3 to 6

[0070] In the support column 7 corresponding to the uplink channel, the second bevel gear 103 needs to be located at the "front side" of the first bevel gear 101 (based on the rotation direction), when the first bevel gear 103 is horizontally rotated out with the support column, the meshing transmission makes the first bevel gear 101 rotate clockwise, driving the illuminating lamp 11 to flip upward.

[0071] In the support column 7 corresponding to the downlink channel, the second bevel gear 103 needs to be located at the "rear side" of the first bevel gear 101 (symmetrically opposite to the front side), at this time, the first bevel gear 101 will rotate counterclockwise, driving the illuminating lamp 11 to flip downward.

[0072] This symmetric position difference changes the relative positions of the meshing bevel gears, so that the rotation directions of the two first bevel gears are opposite, and finally the reverse flipping of the two illuminating lamps is realized, which accurately matches the functional needs of the "upward inclination" of the uplink channel and the "downward inclination" of the downlink channel.

[0073] In the development process, it is found that in daily scenes, wide-angle illumination is needed to cover the stair platform, and in fire scenes, strong spotlight is needed to penetrate smoke, and fixed light sources cannot meet both needs, resulting in insufficient scene adaptability. Therefore, another embodiment of the present application is designed for the structure of the illuminating lamp 11:

[0074] The illuminating lamp 11 includes a lamp body 111 fixed to the flipping shaft 2, the axis of the lamp body 111 is perpendicular to the axis of the flipping shaft 2, forming a spatial layout of "horizontal illumination + vertical flipping". A circular truncated cone-shaped channel (the large end faces outward and the small end faces inward) is penetrated along the axis in the lamp body 111, a transparent glass 112 (for protection and light transmission) is fixed at the large end of the channel, and a cover 113 (to close the inner side of the channel and prevent dust from entering) is fixed at the small end of the channel.​

[0075] The LED chip 114 is movably arranged in the lampshade 11 and is electrically connected with the main control module. The LED chip 114 can move along the axis of the lamp body 111 to adjust the position.

[0076] In the daily state, the LED chip 114 is located inside the large end of the passage, and the light is diffused by the circular truncated cone structure to form a wide-angle light beam, which uniformly covers the platform area. In the fire state, the LED chip 114 is located inside the small end of the passage, and the light is converged by the circular truncated cone structure to form a strong spotlight, the energy is more concentrated, the smoke penetration ability is significantly enhanced, and the deep steps in the passage can be accurately illuminated.

[0077] Specifically, the side of the LED chip 114 close to the cover 113 is fixed with a traction rope 3, the traction rope 3 movably passes through the cover 113 and is fixed with the fixed frame 9 (the fixed frame 9 is rigidly connected with the support column 7 and does not rotate with the rotating shaft 2), and a plurality of reset springs 4 are connected between the LED chip 114 and the cover 113. In the natural state (when the lighting lamp 11 is not turned over), the reset spring 4 is in an extended state, and the traction rope 3 is in a horizontal straight state, and the two work together to stabilize the LED chip 114 inside the large end of the passage.

[0078] When a fire occurs, the lighting lamp 11 rotates upward / downward with the rotating shaft 2 (adapted to the inclination angle of the up-down passage), and since the fixed frame 9 remains stationary, the traction rope 3 rotates from the horizontal state to the V-shaped state (as shown in FIG. 4) with the lamp body 111, thereby pulling the LED chip 114 to move along the passage axis to the small end, and at the same time, the reset spring 4 is compressed to store energy. Finally, the LED chip 114 is stably located inside the small end under the continuous pulling force of the traction rope 3, and the mode switching from wide-angle lighting to strong spotlight is completed. Figure 8 The design realizes the mechanical switching of the position of the LED chip 114 through the angle linkage of the lamp body rotation and the traction rope 3, without the need for independent driving components. The elastic force of the reset spring 4 is used to ensure stable positioning in the daily state, and the pulling force of the traction rope 3 is used to accurately control the position switching in the fire state. The structure is simple and the response is reliable, which perfectly solves the scene adaptation problem that the fixed light source cannot simultaneously meet the requirements of "daily wide-angle" and "fire spotlight".
