Description

Technical Field

[0001] This invention belongs to the field of fire-fighting lighting equipment technology, specifically relating to an emergency lighting centralized power supply detection device that automatically identifies communication interfaces. Background Technology

[0002] Centralized emergency lighting power supplies are a common type of fire protection equipment in fire emergency lighting and evacuation guidance systems, used to centrally power centralized emergency lighting fixtures. Under normal mains power conditions, it operates in mains power mode, directly outputting mains power or outputting it after voltage conversion. In the event of mains power abnormalities, disconnections, or emergency system control, it switches to emergency mode, outputting its own battery voltage after inversion or stabilization to continuously power the emergency lighting fixtures. To ensure its reliability, its various performance parameters need to be tested, especially the power supply for the emergency lighting fixtures, to obtain parameters such as charging / discharging time, emergency operating time, and charging / discharging performance. This information is then synchronized to the entire fire protection system via the internet for real-time monitoring, allowing access to the testing information of emergency lighting fixtures in every location throughout the building, facilitating subsequent fire management.

[0003] Because emergency lighting fixtures vary in specifications and models, and considering cost and communication performance, different fixtures in different locations use different communication interfaces. Therefore, during the testing process, we need to automatically identify different communication interfaces and then adaptively match them to facilitate subsequent information transmission. Existing communication interfaces are roughly divided into different types such as RS232, RS485, RS422, and USB. Current emergency lighting centralized power supply testing usually involves manual testing and registration, using power testing instruments to test the power supplies of emergency lighting, etc. This testing method is relatively traditional, labor-intensive, and results in scattered data, which is inconvenient for the overall supervision of the fire protection system. Therefore, it is necessary to design an emergency lighting centralized power supply testing device that can automatically identify communication interfaces to solve the above technical problems. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides an emergency lighting centralized power supply detection device that automatically identifies communication interfaces, thereby solving the problems of existing power supply detection devices typically relying on manual detection, resulting in low detection efficiency and wasted manpower.

[0005] An emergency lighting centralized power supply detection device for automatically identifying communication interfaces includes: an emergency lighting lamp body, wherein the right end of the emergency lighting lamp is provided with a first communication interface connected to its internal battery; characterized in that it further includes a rectangular tube with open ends on both sides and disposed outside the first communication interface, wherein the end of the rectangular tube facing the first communication interface is provided with a positioning device to ensure that the center of the rectangular tube is kept consistent with the center of the first communication interface.

[0006] The upper and lower ends of the rectangular tube are respectively connected to fixed blocks placed on the right side of the positioning device. The fixed block has a receiving groove at one end facing the center of the rectangular tube. A trapezoidal slider is slidably connected in the vertical direction inside the receiving groove. The inclined surface of the trapezoidal slider is set towards the left opening direction. A first spring is connected between the tail end of the trapezoidal slider and the bottom surface of the receiving groove. A telescopic conductive contact is connected to the right end face of the tail of the trapezoidal slider. The right end of the telescopic conductive contact extends out of the outer wall of the receiving groove. Fixed columns placed on the right side of the receiving groove are respectively vertically installed on the upper and lower ends of the rectangular tube. Multiple sets of resistance coils are wound around the fixed columns. The resistance coils are in contact with the telescopic conductive contacts on the corresponding sides. The resistance coils and telescopic conductive contacts are respectively connected to the power supply.

[0007] The rectangular tube external connection and fixing device satisfies the requirement of reliably connecting the rectangular tube to the emergency lighting fixture. The right end of the rectangular tube is connected to a circular tube. The circular tube is longitudinally rotatably connected to a rotating shaft. Multiple sets of radially arranged electric telescopic rods are installed outside the rotating shaft. The ends of the electric telescopic rods are equipped with second communication interfaces that cooperate with the first communication interface. The specifications and models of the multiple sets of second communication interfaces are different. The circular tube extends from the end of the rotating shaft and is coaxially connected to the output shaft of the drive motor installed outside the circular tube at the end.

[0008] The cylindrical tube has a built-in power detection system, and the resistance coil is connected to an ammeter. The ammeter, power detection system, drive motor, and electric telescopic rod are all electrically connected to a controller installed inside the cylindrical tube.

[0009] Preferably, the positioning device includes a first L-shaped plate installed on the front and rear end faces of the rectangular tube and a second L-shaped plate installed on the upper and lower end faces. The L-shaped plate is rotatably connected to a sleeve in the direction perpendicular to its direction. The sleeve is internally threaded to a lead screw. A limit structure is provided between the lead screw and the sleeve to restrict the lead screw to move only along the axial direction of the sleeve. An arc-shaped rod is installed at the end of the lead screw facing the center of the rectangular tube. A spur gear is coaxially installed on the outside of the sleeve. The right sides of the two sets of spur gears on the front and rear sides are meshed with a first gear ring rotatably connected to the outside of the sleeve. The right sides of the two sets of spur gears on the upper and lower sides are meshed with a second gear ring rotatably connected to the outside of the sleeve. The radius of the first gear ring is smaller than that of the second gear ring, and the first gear ring and the second gear ring are coaxially arranged. A first drive handle is installed on the outside of the first gear ring, and a second drive handle is installed on the outside of the second gear ring, located to the left of the first drive handle.

[0010] Preferably, the lead screw has a rectangular groove along the axial direction, and the end of the rectangular cylinder is connected to a limiting rod that slides with the rectangular groove. The limiting rod and the rectangular groove form a limiting structure.

[0011] Preferably, the inner sidewalls of the first and second gear rings have circumferentially arranged groove structures with rectangular cross-sections. The rectangular cylinders are respectively equipped with locking rods that slide circumferentially with the groove structures of the first and second gear rings, thereby forming a rotating connection structure between the first and second gear rings.

[0012] Preferably, the telescopic conductive contact includes a circular fixed cylinder installed at the tail of the trapezoidal slider. The right end of the fixed cylinder is slidably connected to a conductive head that contacts and engages with the resistance coil on the corresponding side. A second spring is connected between the conductive head and the inner bottom surface of the fixed cylinder. The conductive head and the resistance coil on the corresponding side form a sliding rheostat structure.

[0013] Preferably, the fixing device includes extension plates installed at two corners outside the rectangular tube, with a transversely damped sliding connection light rod inside the extension plate, one end of the light rod being connected to a suction cup and the other end being connected to a drive disk.

[0014] Preferably, when the second communication interface and the first communication interface are in the same horizontal direction, their centers are aligned.

[0015] The beneficial effects of this invention are:

[0016] This invention proposes an emergency lighting centralized power supply detection device for automatic identification of communication interfaces. A rectangular cylinder is installed around different types of communication interfaces. Inside the rectangular cylinder, a screw structure adjusts the position of arc-shaped rods in four directions, clamping and positioning the first communication interface in all four directions, ensuring the first communication interface is aligned with the center of the rectangular cylinder. Receiving grooves are provided on the top and bottom of the rectangular cylinder, each containing a trapezoidal slider. The movement of the trapezoidal slider causes relative displacement between its telescopic conductive contact and a resistance coil outside the rectangular cylinder. This resistance-current change determines the height of the first communication interface, thus identifying it. A circular cylinder at the right end of the rectangular cylinder, controlled by a controller, matches the corresponding second communication interface with the first, completing the insertion and installation. This facilitates subsequent testing. This invention is easy and simple to operate, automatically identifies and inserts different types of communication interfaces, saves manpower, has a high degree of automation, is widely applicable, and highly practical, making it suitable for widespread use.

Detailed Implementation

[0029] The foregoing and other technical contents, features and effects of the present invention are described in conjunction with the appendix below. Figures 1 to 11 The detailed description of the embodiments will clearly demonstrate this. All structural details mentioned in the following embodiments are based on the accompanying drawings.

[0030] In the description of this invention, it should be understood that the terms "front", "rear", "left", "right", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0031] Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings.

[0032] Example 1: As Figures 1-11 As shown, an emergency lighting centralized power supply detection device for automatically identifying communication interfaces includes an emergency lighting lamp 1 body. The right end of the emergency lighting lamp 1 is provided with a first communication interface 2 connected to its internal battery. The first communication interface 2 can transmit power data information to the outside through the communication interface, thereby completing data storage and recording. However, the model and specifications of the first communication interface 2 are selected according to the functions to be performed, and cost must also be considered. Therefore, the models of communication interfaces from different manufacturers will be different according to their application scenarios. However, in the prior art, manual operation is often used to connect different models of communication interfaces, which is inefficient. Therefore, the present invention improves the existing structure and can automatically identify different types of communication interfaces. The device also includes a rectangular tube 3 with openings at both ends and located outside the first communication interface 2. The size of the rectangular tube 3 is larger than the size of the first communication interface 2. A positioning device is provided at the end of the rectangular tube 3 facing the first communication interface 2 to ensure that the center of the rectangular tube 3 is consistent with the center of the first communication interface 2. The positioning device is to keep the center of the rectangular tube 3 consistent with the center of the first communication interface 2, so as to facilitate the subsequent identification of the model of the first communication interface 2 and the positioning of the subsequent connection of the second communication interface 14, and to avoid the problem of not being able to connect.

[0033] The upper and lower ends of the rectangular tube 3 are respectively connected to a fixing block 4 placed on the right side of the positioning device. A receiving groove 5 is opened at the end of the fixing block 4 facing the center of the rectangular tube 3. A trapezoidal slider 6, placed inside the rectangular tube 3, is slidably connected vertically within the receiving groove 5. The inclined surface of the trapezoidal slider 6 faces the left opening direction. Contact and engagement between the inclined surface and the first communication interface 2 will push the trapezoidal slider 6 into the receiving groove 5. A first spring 7 is connected between the tail end of the trapezoidal slider 6 and the bottom surface of the receiving groove 5. The first spring 7 serves to reset the trapezoidal slider 6. A telescopic conductive contact 8 is connected to the right end face of the tail of the trapezoidal slider 6. The right end extends outward from the outer wall of the receiving groove 5. The end of the receiving groove 5 is outside the rectangular tube 3. A sliding hole is opened on the right end face at this position. The telescopic conductive contact 8 includes a circular fixed tube 29 installed at the tail of the trapezoidal slider 6. The fixed tube 29 slides vertically in the sliding hole. The right end of the fixed tube 29 is slidably connected to a conductive head 30 that contacts and cooperates with the resistance coil 10 on the corresponding side. A second spring 31 is connected between the conductive head 30 and the inner bottom surface of the fixed tube 29. The conductive head 30 and the resistance coil 10 on the corresponding side form a sliding rheostat structure. One end of the resistance coil 10 is connected to an ammeter, and the other end is connected to a power supply. The ammeter is connected to a controller. The controller collects current parameters to form a current meter. Figure 11The judgment circuit shown.

[0034] The upper and lower end faces of the rectangular tube 3 are vertically mounted with fixed posts 9 placed on the right side of the receiving groove 5. Multiple sets of resistance coils 10 are wound around the fixed posts 9. The resistance coils 10 contact and cooperate with the telescopic conductive contacts 8 on the corresponding sides. The resistance coils 10 and the telescopic conductive contacts 8 form a judgment circuit. The resistance coils 10 and the conductive heads 30 form a sliding rheostat structure. When the first communication interface 2 is connected to the second communication interface 14, the resistance formed by the contact between the resistance coils 10 and the conductive heads 30 is different due to the different widths of different types of communication interfaces. As a result, the current formed in the circuit is different. By accurately judging the position of the communication interface in the vertical direction, the corresponding port information can be identified. The judgment circuit will change the resistance according to the value of the communication interface at different heights, thereby forming different currents in the judgment circuit, thus identifying the information of the communication port. The change of resistance-current can provide feedback on small changes in stroke, thereby accurately identifying the port height information and preparing to judge the port information of the communication port. The circuit principle here is to connect the conductive head 30 and the resistance coil 10 in the circuit with wires, and then connect an ammeter in the circuit. The controller collects the ammeter value to judge the port with different widths, thus forming a judgment circuit. The controller collects current data, and the judgment circuit collects different current magnitudes to feed back the different widths of the communication port, thereby making an adaptive selection for subsequent port selection.

[0035] The external fixing device of the rectangular tube 3 is designed to reliably connect the rectangular tube 3 to the emergency lighting fixture 1. The fixing device is used to fix the device to the lighting fixture after adjustment, preventing the interface from loosening and changing position. Specifically, the fixing device includes extension plates 32 installed on the two corners of the rectangular tube 3. The extension plates 32 are laterally damped and slidably connected to the light rod 33. One end of the light rod 33 is connected to the suction cup 34, and the other end is connected to the drive disk 35. The damping fit between the light rod 33 and the extension plate 32 can be prevented from sliding easily by setting a damping rubber ring inside the mating hole of the extension plate 32. The suction cup 34 is made of a suction cup structure with good adsorption force to the lamp housing. The drive disk 35 facilitates the movement of the suction cup 34.

[0036] The right end of the rectangular tube 3 is connected to the circular tube 11. The circular tube 11 is longitudinally rotatably connected to the rotating shaft 12. Multiple sets of radially arranged electric telescopic rods 13 are installed outside the rotating shaft 12. The ends of the electric telescopic rods 13 are equipped with second communication interfaces 14 that cooperate with the first communication interface 2. The operation of the electric telescopic rods 13 can insert the second communication interface 14 into the first communication interface 2. The multiple sets of second communication interfaces 14 have different specifications and models. When the second communication interface 14 and the first communication interface 2 are in the same horizontal direction, their centers are consistent, thereby avoiding the situation where the two cannot be connected. The end of the rotating shaft 12 extends into the circular tube 11 and is coaxially connected to the output shaft of the drive motor 15 installed outside the circular tube 11. The drive motor 15 adopts a standard servo motor, which can accurately control the rotation angle of the output shaft.

[0037] The cylindrical tube 11 houses a power detection system. An ammeter is connected to the resistance coil. The ammeter, power detection system, drive motor 15, and electric telescopic rod 13 are all electrically connected to a controller installed inside the cylindrical tube 11. The power detection system can connect to the fire protection system's internet via wireless or wired connection, transmitting data to the fire management system in real time. The controller is made using an integrated circuit, employing a microcontroller such as STC89C51RC or C8051F331 / 330. The microcontroller is used for data acquisition and control. The selection of the working state of each device is easily implemented by those skilled in the art and will not be elaborated here. In this embodiment, during use, the rectangular cylinder 3 is first moved to the position of the first communication interface 2. The center position of the rectangular cylinder 3 is aligned with the center position of the first communication interface 2 by rotating the positioning device. After adjustment, the rectangular cylinder 3 is moved to the left. The right end of the first communication interface 2 will contact the inclined surface of the trapezoidal slider 6, pushing the trapezoidal slider 6 into the receiving groove 5 and compressing the first spring 7. During the movement, the conductive head 30 on the trapezoidal slider 6 changes its resistance value in conjunction with the resistance coil 10. This changes the current magnitude in the judgment circuit. After the current data stabilizes, the controller collects and judges the current data, and then drives the drive motor 15 to work. The second communication interface 14, which matches the first communication interface 2, is rotated to the same horizontal direction as the first communication interface 2. Then, the corresponding electric telescopic rod 13 is controlled to work, inserting the second communication interface 14 into the first communication interface 2 to achieve connection. Then, the detection button of the emergency lighting fixture is turned on. At the same time, the tester pushes the drive plate 35 to reliably attach the suction cup 34 to the outside of the lighting fixture housing, so that it will not easily shift or... Once the device is loosened, the power detection system is activated via the controller to test the power performance of the lighting fixtures. Simultaneously, the data is synchronized via the internet. After the test is complete, the power is turned off. The suction cup 34 is then detached from the lighting fixture, and the entire device is pulled out of the first communication interface 2. The positioning device is then returned to its initial position. This embodiment is convenient and simple to operate, automatically identifying and connecting different communication interfaces, saving manpower. Power performance data for each lighting fixture is collected centrally and updated in real time. Compared to subsequent fire protection system management, it has a high degree of automation, wide applicability, and strong practicality, making it suitable for widespread use.

[0038] In Embodiment Two, based on Embodiment One, the positioning device includes a first L-shaped plate 16 installed on the front and rear end faces of the rectangular tube 3, and a second L-shaped plate 17 installed on the upper and lower end faces. The L-shaped plates are rotatably connected to sleeves 18 in a direction perpendicular to their respective directions. Each L-shaped plate in each direction has a sleeve 18 rotatably positioned in a direction perpendicular to the L-shaped plate. The positions of the two sets of sleeves 18 in the same direction must be consistent. A lead screw 19 is internally threaded onto each sleeve 18. A limit structure is provided between the lead screw 19 and the sleeve 18 to restrict the lead screw 19 to move only along the axial direction of the sleeve 18. The structure is used to limit the relative rotation between the lead screw 19 and the sleeve 18, so that the lead screw 19 can be fed along the axial direction of the sleeve 18 during rotation. Specifically, the lead screw 19 has a rectangular groove 26 along the axial direction. The end of the rectangular cylinder 3 is connected to a limiting rod 27 that slides with the rectangular groove 26. The limiting rod 27 and the rectangular groove 26 form a limiting structure, which together are used to limit the rotation of the lead screw 19. An arc-shaped rod 20 is installed at the end of the lead screw 19 facing the center of the rectangular cylinder 3. The end of the arc-shaped rod 20 is used to contact the outer wall of the first communication interface 2, thereby adjusting the position of the rectangular cylinder 3. The center between the two sets of arc-shaped rods 20 is aligned with the center of the first communication interface 2. Aligning the centers in both directions ensures that the center position is consistent with the center of the rectangular cylinder 3. A spur gear 21 is coaxially mounted on the outside of the sleeve 18. The right sides of the two sets of spur gears 21 on the front and rear sides are meshed with a first gear ring 22 rotatably connected to the outside of the sleeve 18. The right sides of the two sets of spur gears 21 on the upper and lower sides are meshed with a second gear ring 23 rotatably connected to the outside of the sleeve 18. The inner walls of the first gear ring 22 and the second gear ring 23 have circumferentially arranged grooves with rectangular cross-sections. The rectangular cylinder 3 is respectively equipped with grooves that mesh with the first gear ring 22 and the second gear ring 23. The groove structure of the two-tooth ring 23 is circumferentially slidingly fitted with the locking rod 28, thereby forming a rotating connection structure between the first tooth ring 22 and the second tooth ring 23. This allows the first tooth ring 22 and the second tooth ring 23 to be rotatably connected to the outside of the rectangular tube 3 and to rotate relative to the rectangular tube 3. The radius of the first tooth ring 22 is smaller than that of the second tooth ring 23, and the first tooth ring 22 and the second tooth ring 23 are coaxially arranged. A first drive handle 24 is installed on the outside of the first tooth ring 22, and a second drive handle 25 is installed on the outside of the second tooth ring 23, located to the left of the first drive handle 24. The spatial misalignment of the first tooth ring 22 and the second tooth ring 23 facilitates adjustment.

[0039] In this embodiment, when the rectangular cylinder 3 is placed at the position of the first communication port, the first gear ring 22 is rotated to drive the two sets of spur gears 21 in the vertical direction to rotate, which in turn drives the sleeve 18 to rotate, thereby driving the two sets of lead screws 19 in the vertical direction to move and clamp the first communication interface 2 in the vertical direction. It is not advisable to clamp too tightly here, otherwise subsequent vertical movement will be difficult. Then, the second gear ring 23 is rotated to drive the two sets of spur gears 21 in the vertical direction to rotate, which in turn drives the sleeve 18 to rotate, thereby driving the two sets of lead screws 19 in the vertical direction to move and clamp the first communication interface 2 in the vertical direction, thus completing the positioning between the rectangular cylinder 3 and the first communication interface 2.

[0040] In use, the rectangular cylinder 3 is first moved to the position of the first communication interface 2. By rotating the first gear ring 22, the two sets of spur gears 21 in the driving longitudinal direction are rotated, driving the sleeve 18 to rotate, which in turn drives the two sets of lead screws 19 in the driving longitudinal direction to move, clamping the first communication interface 2 in the longitudinal direction. Then, the second gear ring 23 is rotated, driving the two sets of spur gears 21 in the driving vertical direction to rotate, driving the sleeve 18 to rotate, which in turn drives the two sets of lead screws 19 in the driving vertical direction to move, clamping the first communication interface 2 in the vertical direction. This completes the positioning between the rectangular cylinder 3 and the first communication interface 2. After adjustment, the rectangular cylinder 3 is moved to the left, and the right end of the first communication interface 2 contacts the inclined surface of the trapezoidal slider 6, pushing the trapezoidal slider 6 into the receiving groove 5 while compressing the first spring 7. During the movement, the conductive head 30 on the trapezoidal slider 6 changes its resistance value in conjunction with the resistor coil 10, thereby changing the circuit size in the judgment circuit. After the circuit data stabilizes, the current data is collected by the controller. The system performs a data collection and judgment process, then drives the drive motor 15 via the controller to rotate the second communication interface 14, which matches the first communication interface 2, to the same horizontal direction as the first communication interface 2. Then, it controls the corresponding electric telescopic rod 13 to insert the second communication interface 14 into the first communication interface 2, establishing a connection. Simultaneously, the testing personnel push the drive disc 35 to reliably attach the suction cup 34 to the outside of the lighting fixture's housing, preventing easy displacement or loosening. The controller then activates the power detection system to test the power performance and synchronizes the data via the internet. After the test, the power is turned off, the suction cup 34 is detached from the lighting fixture, and the entire device is pulled out of the first communication interface 2. The positioning device is then returned to its initial position. This invention is convenient and simple to operate, automatically identifies and connects different types of communication interfaces, saving manpower. The power performance data of each lighting fixture is collected centrally and updated in real time. Compared to subsequent fire protection system management, it has a high degree of automation, wide applicability, and strong practicality, making it suitable for widespread use.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
