Description

Technical Field

[0001] This utility model relates to the technical field of hot backup devices for industrial switches, specifically to a hot backup device for industrial switches with AC+DC+DC three-way power redundancy. Background Technology

[0002] In critical industrial scenarios such as intelligent manufacturing, rail transportation, and smart grids, the continuous operation of network equipment directly determines production safety and operational efficiency. As core nodes for data transmission, industrial-grade switches face two main risks: power outages caused by complex power supply environments and equipment malfunctions.

[0003] In the prior art, the solutions most similar to the technical field and solution approach of this patent can be divided into two categories: dual-power redundant power supply solutions and software protocol-based hot backup solutions. Their technical features and limitations are as follows: Dual power supply redundancy solutions only support two power inputs of the same type or two categories, which cannot be adapted to industrial scenarios where there is both AC mains power and two DC power supplies. An additional AC / DC converter is required, which increases the cost and size. Switching is achieved by relying on relays or simple voltage comparators, and the response time is usually >50ms. In extreme cases, the device may restart due to the switching gap. Software protocol-based hot backup solutions use software protocols to synchronize and switch the status of primary and backup devices. However, the synchronization latency is relatively large, typically >8ms, which may lead to instruction loss and accidents in low-latency scenarios such as rail transit dispatching. The synchronization logic runs on the main CPU, and if the chip is overloaded or subject to electromagnetic interference, it may cause switching failure. In cold backup mode, configuration needs to be manually imported, which can easily lead to secondary business failures due to operational errors. Utility Model Content

[0004] To address the issues of poor power supply reliability, service continuity, and overall reliability in the existing technologies, as well as the inconvenience of installation, this invention provides a hot backup device for industrial switches with AC+DC+DC three-way power supply redundancy. This invention is achieved through the following technical solution.

[0005] A hot backup device for an industrial switch with AC+DC+DC three-way power redundancy includes a device body, mounting components and mounting base. The device body includes a main enclosure and a PoE 60W port on one side of the main enclosure.

[0007] As a preferred embodiment of this utility model, the fixing member includes a fixing screw and a limiting ring fixedly connected to the fixing screw, and one end of the fixing screw is provided with a locking head.

[0008] In a preferred embodiment of this utility model, the fixing screw moves up and down inside the fixing seat, and the fixing screw and the fixing seat are connected by a thread; The engaging head is engaged and fixed with the fixing hole.

[0009] This utility model has the following beneficial effects: 1.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example 1

[0016] Reference Figures 1-5 As shown, this is the first embodiment of the present invention, which provides an industrial switch hot backup device with AC+DC+DC three-way power redundancy. The device includes a main body 10, a mounting assembly 20, and a mounting base 30. The main body 10 includes a main housing 11 and a PoE 60W port 12 disposed on one side of the main housing 11. An AC connection port 13 and a DC connection port 14 are respectively disposed on the upper end of the main housing 11, and the AC connection port 13 and the DC connection port 14 are arranged side by side. A corrugated shell 15 is fixedly connected to both sides of the main housing 11. The corrugated shell 15 is fixedly connected to both sides of the main housing 11 by bolts, which facilitates the installation and removal of the corrugated shell 15.

[0017] The mounting assembly 20 includes a slider 21 and mounting plates 22 connected to both sides of the slider 21. A mounting groove 23 is provided inside the slider 21. Both ends of the slider 21 are fixedly connected to a fixing seat 24, and a fixing member 25 is provided inside the fixing seat 24. The sliding parts 21 are symmetrically arranged on both sides of the bottom of the main housing 11, and the mounting plate 22 is fixedly connected to both sides of the sliding parts 21, while the fixing seat 24 is fixedly connected to the front and rear ends of the sliding parts 21; furthermore, the sliding parts 21, the mounting plate 22 and the fixing seat 24 can be processed by integral molding. Furthermore, by bolting the mounting plate 22 onto the main housing 11, the mounting assembly 20 can be disassembled and installed.

[0018] The mounting base 30 includes a mounting base 31 and a mounting slide rail 32 connected to the mounting base 31, and fixing holes 33 are evenly provided on the upper side of the mounting slide rail 32. The mounting slide rails 32 are symmetrically arranged on the mounting base plate 31, so that the mounting slide rails 32 and the mounting slide grooves 23 can be slidably connected. At the same time, the fixing holes 33 are evenly arranged on the mounting slide rails 32 to facilitate engagement with the fixing parts 25 and complete the adjustment of the installation position.

[0019] Furthermore, the cross-sectional shape of the mounting groove 23 is an equilateral trapezoid, and the short side of the mounting groove 23 is set to face outward; the cross-sectional shape of the mounting rail 32 is the same as that of the mounting groove 23, and the two are fitted together to facilitate connection and prevent easy slippage.

[0020] The fastener 25 includes a fixing screw 251 and a limiting ring 252 fixedly connected to the fixing screw 251, and a locking head 253 is provided at one end of the fixing screw 251; The fixing screw 251 moves up and down inside the fixing base 24, and the fixing screw 251 and the fixing base 24 are threaded together; the engaging head 253 is engaged and fixed with the fixing hole 33; the engaging head 253 is designed to facilitate engagement with the fixing hole 33. Furthermore, the limiting ring 252 moves within the fixed base 24 to limit movement and prevent the fixing member 25 from detaching from the fixed base 24; furthermore, the outer side of the engaging head 253 is provided with an inclined surface, and the shape of the fixing hole 33 is the same as that of the engaging head 253, so as to facilitate the cooperation between the two.

[0021] First, place the main body 10 of the device above the mounting component 20 at the corresponding position. Then, use bolts to fix the main body 10 of the device to the mounting component 20. Next, align the mounting groove 23 of the mounting component 20 with the mounting rail 32 on the mounting base 30. Utilizing the fact that the two have the same cross-sectional shape, the mounting groove 23 and the mounting rail 32 are slidably connected. Then, rotate the fixing screw 251 so that the engaging head 253 at one end of the fixing screw 251 is aligned with the fixing hole 33 on the upper side of the mounting rail 32, so that the engaging head 253 engages into the fixing hole 33. This completes the initial installation and positioning of the mounting component 20 on the mounting base 30. At the same time, the threaded connection between the fixing screw 251 and the fixing base 24 fixes the position of the fixing screw 251, thus securing the installation. When disassembly is required, simply follow the reverse order. First, release the engagement between the locking head 253 and the fixing hole 33, slide the device out of the mounting groove 23 along the mounting slide rail 32, and then remove the bolts connecting the main body 10 and the mounting assembly 20. This allows for easy separation of the components, facilitating maintenance or component replacement. This not only simplifies the assembly process but also improves the flexibility and operability of the entire device during on-site deployment.

[0022] The AC+DC+DC three-way power supply redundancy subsystem enables seamless switching between AC mains power and two DC power supplies, wide-range adaptability, and anti-interference protection. Industrial power supply environments are complex, and a single power supply interruption can easily cause switch shutdown, leading to the paralysis of the entire industrial network. Three-way power supply redundancy improves power supply reliability from the source through multi-path, multi-type power supply backup, covering all industrial power supply scenarios. It is highly adaptable, with the three AC+DC+DC power supplies capable of simultaneously connecting to two types of power supply without the need for additional power converters. It can directly adapt to over 99% of industrial power supply environments, reducing the complexity of on-site deployment.

[0023] To avoid single-point power supply failures and maximize power supply reliability, under normal circumstances, the three power supplies can share the load and switch between primary and backup power supplies to avoid overload of a single power supply. If the AC mains power is interrupted, the two DC power supplies will immediately take over the power supply without any switching gap. If one of the DC power supplies fails, the other DC power supply can still provide power independently, and the AC power supply can also serve as a backup. In extreme cases, even if the AC and one DC power supply fail simultaneously, the switch can still operate normally with only one DC power supply remaining.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
