Description

Technical Field

[0001] This utility model relates to the field of fire protection and security equipment technology, specifically a multi-functional intelligent gateway. Background Technology

[0002] Current fire alarm systems mostly adopt a discrete product architecture based on international standards such as EN54 and CCC, with various functional devices deployed independently. For example, manual alarm buttons, audible and visual sirens, wireless sensor terminals, and network transmission modules all exist in independent forms. Although this design meets the requirements of traditional fire protection systems for functional reliability and standard compliance, it has revealed significant limitations in practical applications.

[0003] Existing fire protection IoT systems suffer from low integration. Different devices with different functions require independent power supply and wiring, resulting in high costs and long lead times, which severely restricts the efficiency of fire safety upgrades. Secondly, they lack compatibility. Different functional devices typically use heterogeneous communication protocols, making it difficult to achieve unified networking. This leads to poor system scalability and an inability to meet the needs of multi-terminal collaborative early warning systems such as smoke detectors and door sensors in the IoT era. Finally, they lack intelligence. Traditional audible and visual alarm devices have fixed functions and cannot dynamically adjust alarm modes through remote programming. They also lack 4G / 5G and other wide area network access capabilities, making it difficult to integrate into a smart fire protection cloud platform and creating information silos. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a highly integrated, multi-protocol fusion and wireless IoT-enabled new gateway device, a multi-functional smart gateway, to solve the technical problems of dispersed hardware architecture and communication mode layout, low integration, and poor intelligence in existing fire alarm systems.

[0005] This utility model discloses a multifunctional smart gateway, comprising: a protective housing, the protective housing forming a sealed cavity with a front opening, the side of the sealed cavity away from the opening being a mounting base; a core functional module, the core functional module being integrated on the mounting base, the core functional module including: a manual alarm trigger module, the manual alarm trigger module including a glass-breaking switch protruding from the front surface of the protective housing; a multi-mode communication unit, the multi-mode communication unit including a heterogeneous integrated architecture of a dual baseband chip and a LoRa communication chip, the dual baseband chip being configured with redundant radio frequency link interfaces; an audible and visual alarm module, the audible and visual alarm module including a buzzer with a directional amplification structure and a ring-shaped LED light group; and a smart power supply system, the smart power supply system including a main power interface disposed on one side of the mounting base and an embedded backup battery, the main power interface being connected to external mains power through a wiring compartment.

[0008] As a further improvement of this utility model, the operation panel of the glass breakage switch is provided with a luminous indicator, the shape and size of the glass breakage switch are adapted to the shape and size of the opening, and a slot that fits the mounting bracket is provided on the back of the glass breakage switch.

[0009] As a further improvement of this utility model, the outer surface of the protective housing has a ring array of sound-amplifying holes, which are connected to the inner cavity of the protective housing. The buzzer is mounted on the mounting base and corresponds to the position of the sound-amplifying holes.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention systematically solves the problems of dispersion, low compatibility, and insufficient intelligence in traditional fire alarm systems through deep integration of hardware architecture and fusion reconstruction of communication technology. By physically integrating the cavity enclosure and the mounting base plate, core units such as the manual alarm trigger module, audible and visual alarm module, communication chipset, and power supply module are arranged in a compact manner.

However, it should be understood that these physical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these physical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and components will be shown in a simple schematic manner in the illustrations.

[0026] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0027] In the description of this technology, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this technology based on the specific circumstances.

[0028] Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0029] Please see Figure 1-8This utility model discloses a multifunctional smart gateway, comprising: a protective housing 1, which forms a sealed cavity with a front opening 13, and a mounting base 11 on the side of the sealed cavity away from the opening 13; a core functional module, which is integrated on the mounting base 11 and includes: a manual alarm trigger module 2, which includes a glass-breaking switch 21 protruding from the front surface of the protective housing 1; a multimode communication unit 4, which includes a heterogeneous integrated architecture of a dual baseband chip 44 and a LoRa communication chip 43, and the dual baseband chip 44 is configured with redundant radio frequency link interfaces; an audible and visual alarm module 3, which includes a buzzer 31 with a directional amplification structure and a ring-shaped LED light group 33; and a smart power supply system 5, which includes a main power interface 52 and an embedded backup battery 51 disposed on one side of the mounting base 11, and the main power interface 52 is connected to the external mains power through a wiring compartment.

[0030] The dual baseband chip 44 integrates dual SIM card slots 41, which support 4G / 5G dual-mode communication and form a dual-channel redundant transmission link for cellular network and LPWAN with the LoRa communication chip 43.

[0031] In this embodiment, "dual baseband chip 44" refers to a chipset that integrates two different baseband processing functions, such as a processor chip combination compatible with 4G and 5G protocols; "redundant RF link interface" refers to a backup RF channel interface component that is automatically activated when the main communication link fails, enabling physical dual-channel switching; "directional amplification structure" specifically refers to a buzzer 31 amplification component with a sound wave guiding cavity design, which contains a conical reflector and a sound wave concentrator; "cable bay" refers to a cable entry channel with a waterproof sealing ring set on the side wall of the protective housing 1.

[0032] Regarding the connection relationship, when the "main power interface 52" is connected to the external mains power through the wiring compartment, a circular wire hole with a diameter of 8-12mm can be opened on the side wall of the protective housing 1. A rubber sealing ring is installed in the hole. After the power cord passes through the sealing ring, it is crimped to the terminal of the main power interface 52. As for the "core function module" integrated on the mounting base plate 11, in actual installation, each function module can be soldered onto the PCB circuit board first, and then the PCB board can be fixed onto the aluminum alloy mounting base plate 11 with screws. The modules are electrically connected through PCB traces. The glass break switch 21 is pre-pressed and installed on the mounting base plate 11. Its bottom contacts are made in contact with the conductive pads on the base plate through elastic probes.

[0033] It should be noted that the arrangement of the "ring-shaped LED light group 33" does not mean that the light group itself is in a ring structure, but rather that multiple LED beads are arranged at equal intervals along the circumference of the protective shell to form a ring warning strip; the heterogeneous integrated architecture should be understood as the dual baseband chip 44 and the LoRa communication chip 43 adopting a physically separate but logically coordinated working mode. The dual baseband chip 44 handles cellular network communication, and the LoRa communication chip 43 is responsible for low-power wide area network communication. The two interact with each other through the SPI bus.

[0034] By integrating manual alarm, multi-mode communication, audible and visual alarms, and intelligent power supply system, the technical problems of weak emergency response capability and poor communication reliability of traditional gateways are solved. In particular, the redundant RF link design ensures system availability in the event of a single communication module failure; the directional amplification structure enhances the propagation of alarm sound waves in a specific direction, improving alarm recognition rate; and the cable management compartment structure balances the convenience of cable introduction with the airtightness of the housing, improving the product's environmental adaptability.

[0035] Please see Figure 3 and Figure 4 In this embodiment, the glass-breaking switch 21 is fixed on the mounting substrate 11 by the mounting bracket 22. A docking terminal 42 is installed on the mounting substrate 11 at the position between the dual baseband chips 44. The glass-breaking switch 21 is electrically connected to the docking terminal 42. This design makes;

[0036] The operation panel of the glass break switch 21 is equipped with a night light indicator. The shape and size of the glass break switch 21 are adapted to the shape and size of the opening 13. The back of the glass break switch 21 has a slot that fits into the mounting bracket 22.

[0037] The glass-breaking switch 21 is fixed to the mounting base 11 by a 1.2mm thick 304 stainless steel stamped mounting bracket 22, which is fixed by three-point welding. A gold-plated copper alloy mating terminal 42 is positioned at the center of the dual baseband chips 44 with a spacing of 15mm on the surface of the mounting base 11. The bottom of the terminal is soldered to the pins of the glass-breaking switch 21 via a 0.8mm diameter tin-plated copper wire. A 3.2mm deep T-shaped groove is provided on the back of the switch, forming an interference fit with the 5mm wide protrusion at the top of the mounting bracket 22.

[0038] Please see Figure 1 and Figure 3 Furthermore, the outer surface of the protective housing 1 has a ring array of sound-amplifying holes 32, which are connected to the inner cavity of the protective housing 1. A buzzer 31 is mounted on the mounting base plate 11 and corresponds to the position of the sound-amplifying holes 32. An LED light group 33 is mounted on the outer peripheral wall of the protective housing 1 at the position located on the side of the sound-amplifying holes 32.

[0039] The protective housing 1 employs an 8-part annular array layout for the sound-amplifying holes 32. Each group contains 8 circular holes with a diameter of 3mm. The axis of the holes forms a 45° angle with the normal to the housing surface, resulting in an effective sound wave diffusion angle ≥120°. The buzzer 31 uses an SMD-3528 surface-mount piezoelectric element. Its sound-emitting surface maintains a 2mm gap with the sound-guiding cavity on the back of the sound-amplifying hole 32. The cavity volume is designed to be 850±50mm³ to optimize low-frequency response. The LED light group 33 consists of 6 OSRAM 2835 surface-mount LEDs, arranged circumferentially around the housing at intervals of 5mm to the right of the sound-amplifying hole 32, with a spacing of 22mm between the LEDs. The surface is covered with an IP67-rated waterproof and light-transmitting silicone cover, enabling 360° visible light warning.

[0040] Please see Figure 2 and Figure 4 It should be noted that the backup battery 51 is mounted on the mounting base plate 11. The horizontal height of the backup battery 51 after mounting is higher than the horizontal height of the LoRa communication chip 43, and it is arranged in an n-shape above the LoRa communication chip 43.

[0041] A relay 53 is installed on the mounting base plate 11 near one end of the backup battery 51. The relay 53 is used to control the backup battery 51 to provide emergency power after the mains power is cut off.

[0042] The backup battery 51 uses two parallel sets of 18650 lithium-ion cells, mounted on a height-adjustable n-type aluminum alloy bracket. The bracket column height is 32mm, ensuring a 28mm clearance between the bottom of the battery and the reference surface of the mounting substrate 11, and 15mm above the LoRa communication chip 43 module. The relay 53 is an Omron G5RL-1A-E type dual-contact relay, installed 10mm from the edge of the battery bracket. Its control circuit and mains power monitoring circuit form a closed-loop detection system. When a mains power interruption is detected, it can complete the backup power switching within 0.5 seconds, with a voltage drop of ≤0.2V during the switching process.

[0043] Please see Figure 5 and Figure 7 Specifically, the protective housing 1 has a fixing back plate 6 on the back for fixing to the wall, the fixing back plate 6 has multiple fixing holes 61, and the protective housing 1 has a hanging hole 12 on the back for hanging with the fixing back plate 6.

[0044] The fixed back plate 6 is made of 2mm thick anodized aluminum alloy plate, with 4 sets of rectangularly distributed M4 threaded mounting holes (hole spacing 120×80mm) on the back. The front is stamped with a dovetail groove hook structure with a depth of 5mm. The hook hole 12 on the back of the protective shell 1 is an L-shaped opening 13 groove design, with a groove width of 8.2mm and a depth of 12mm. The opening 13 end is chamfered with 3mm for easy assembly. An EPDM rubber buffer pad (Shore hardness 60±5) is placed between the shell and the back plate. After hooking, the overall structure can withstand a torsional load of 50Nm without displacement.
