Description

Technical Field

[0001] The present invention relates to the field of routers, and particularly to a modular access router for information system integration services. Background Art

[0002] As the core network device of modern information systems, modular access routers support multi-protocol access and heterogeneous network integration through pluggable hardware modules (such as 5G modules, industrial protocol conversion cards), and are widely used in scenarios such as smart cities and industrial Internet of Things. Traditional solutions adopt a hierarchical architecture design, integrating functions such as routing and forwarding, security encryption, and edge computing, and relying on standard interfaces to achieve service expansion. However, their dynamic environment adaptability and long-term operation stability still have limitations.

[0003] At present, the degree of router operation and maintenance automation is low, lacking the ability of accurate fault prediction. When there is a memory leak or protocol anomaly, manual on-site restart is required, and the restart process causes the loss of key data. The environmental adaptability is poor, and protocol switching depends on manual configuration, which cannot meet the stringent requirements of intelligent manufacturing for real-time performance. In addition, due to the small size and light weight of the router, and its wiring terminals often need to be connected to various cables during use, traditional routers only set ordinary plastic pads at the bottom for anti-slip, and the anti-slip effect is poor, and it only has a certain anti-slip effect in the horizontal direction. When stressed in other directions, or when the cable is pulled, it is very easy to displace, and the device displaces, causing the interface to loosen or even fall off, thus affecting the use.

[0004] Therefore, it is necessary to propose a modular access router for information system integration services to solve the above problems. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the defects existing in the prior art. The present invention proposes a modular access router for information system integration services, which solves the problems of low degree of router operation and maintenance automation and poor stability in the prior art in the background art.

[0006] To achieve the above object, the technical solution adopted by the present invention is as follows:

[0007] A modular access router for information system integration services, including a router housing and a circuit board disposed inside the router housing. The circuit board is integrated with:

[0008] A main control module, which is used for system core scheduling and protocol processing;

[0009] A multi-protocol PHY module, which is used for physical layer signal conversion and protocol adaptation;

[0010] An extended communication module, which is used for wireless and cellular network access;

[0011] A security encryption module, which is used for data encryption and trusted verification;

[0012] An edge computing module, which is used for local data processing and intelligent decision-making;

[0013] A self-restart module, which is used for self-healing of device anomalies;

[0014] The self-restart module includes a status monitoring sub-module, a threshold judgment sub-module, and a progressive restart sub-module. The status monitoring sub-module is used to collect the memory leak rate, TCP retransmission rate, and CPU soft error index in real time, and upload data to the main control module at intervals through the SPI bus. The threshold judgment sub-module analyzes the monitoring data based on a multi-parameter fusion model. When the comprehensive index of the memory leak rate, network retransmission rate, and CPU soft error exceeds the preset threshold, it triggers a restart decision. The progressive restart sub-module is used to perform differential snapshot saving, phased service shutdown, and hardware reset, and finally restore the session table from the NOR Flash.

[0015] Preferably, when the progressive restart sub-module performs phased service shutdown and hardware reset, it terminates non-core services in order of priority, namely QoS, protocol conversion, and edge computing. It resets the wireless module, switch chip, and main control in sequence through the MAX6374 hardware watchdog, reads the session table from the NOR Flash, and reconstructs the NAT mapping relationship.

[0016] Preferably, when the progressive restart sub-module performs differential snapshot saving, it only backs up the changed NAT session table, generates incremental data using the CRC32 checksum algorithm, and stores it in the NOR Flash.

[0017] Preferably, the memory leak rate continuously collected by the status monitoring sub-module is where ΔMem is the memory change amount within 5 minutes, and Δt = 300s;

[0018] The TCP retransmission rate is where N retrans is the number of retransmitted packets, and N total is the total number of packets sent;

[0019] The CPU soft error count is E soft ;

[0020] The data sampling interval is 100ms.

[0021] Preferably, the multi-parameter fusion fault prediction model is:

[0022] where 0.1, 0.3, and 0.6 are weight coefficients. When three consecutive monitoring periods satisfy F > 1.5, it is determined that the system is abnormal and a restart decision is triggered.

[0023] Preferably, suction cups are symmetrically arranged at the four corners of the bottom of the router housing.

[0024] Preferably, a pressing and desorbing assembly corresponding to the suction cups is arranged at the four corners of the bottom of the router housing. The pressing and desorbing assembly includes cylinders penetrating through the four corners of the bottom of the router housing. An elevating cylinder is vertically and movably arranged inside the cylinder. The suction cup is communicated and arranged at the bottom of the elevating cylinder. A ventilation pipe corresponding to the elevating cylinder is vertically fixed inside the router housing. The elevating cylinder is movably sleeved outside the ventilation pipe. A sealing plug for sealing the bottom of the elevating cylinder is vertically and movably arranged at the bottom of the elevating cylinder. Ventilation grooves are arranged on the side walls at the upper and lower ends of the ventilation pipe. A first elastic member is arranged between the top of the elevating cylinder and the inner wall of the router housing. A second elastic member is arranged between the bottom of the sealing plug and the inner wall of the suction cup.

[0025] Preferably, a clamping assembly is arranged at the upper end of the elevating cylinder. The clamping assembly includes elastic arms arranged at the upper end of the elevating cylinder. A clamping block is arranged inside the upper end of the elastic arm. The upper end of the clamping block is beveled and the bottom is flat. A locking ring is fixedly arranged on the outer wall of the upper end of the ventilation pipe. The locking ring is in an inverted cone shape. The clamping block is used for clamping and cooperating with the top of the locking ring.

[0026] Preferably, an unlocking assembly is arranged at the upper end of the ventilation pipe. The unlocking assembly includes an unlocking ring movably sleeved on the upper end of the ventilation pipe. The unlocking ring is conical and located above the locking ring. The outer diameter of the unlocking ring is not less than the outer diameter of the locking ring. A groove corresponding to the unlocking ring is arranged on the side wall of the upper end of the ventilation pipe. A protrusion slidingly matched with the groove is arranged on the inner wall of the unlocking ring. A third elastic member is arranged between the bottom of the protrusion and the inner bottom of the groove.

[0027] Preferably, a limiting slide bar parallel to the axis of the ventilation pipe is arranged on the side wall of the ventilation pipe. A limiting slideway corresponding to the limiting slide bar is arranged on the inner wall of the elevating cylinder. The limiting slide bar and the limiting slideway are in sliding and guiding cooperation.

[0028] Compared with the prior art, the beneficial effects of the present invention include:

[0029] 1. For the modular access router of the information system integration service, the self-restart module realizes fault early warning by intelligently integrating multi-dimensional operation parameters, accurately locates abnormal components and triggers a differential hot restart mechanism, and only performs directional recovery on the faulty unit, effectively avoiding the complete interruption of services caused by traditional whole-machine restart. The progressive recovery process combines high-speed storage technology to complete the preservation of key data and the reconstruction of the state in an extremely short time, compressing the service interruption duration to a negligible range and achieving the telecommunication-level high availability standard.

[0030] 2. The modular access router of this information system integration service can increase the stability of the router housing during use through the suction cups provided, avoiding displacement caused by external forces such as cable pulling. It cooperates with the pressing and detaching component, the clamping component, and the unlocking component, and can achieve adsorption and release of adsorption by pressing. The structure is compact and easy to use. At the same time, there is a large gap between the bottom of the router housing and the horizontal plane, which is also convenient for heat dissipation.

Detailed implementation manners

[0042] It is easy to understand that according to the technical solution of the present invention, without changing the essence of the present invention, those of ordinary skill in the art can propose various structural ways and implementation ways that can be mutually replaced. Therefore, the following detailed implementation manners and the accompanying drawings are only exemplary descriptions of the technical solution of the present invention, and should not be regarded as all of the present invention or regarded as a limitation or restriction on the technical solution of the present invention.

[0043] According to an embodiment of the present invention in combination with Figures 1-9 Shown as

[0044] As Figures 1-3 As shown, a modular access router for information system integration services includes a router housing 1 and a circuit board 2 disposed inside the router housing 1. The circuit board 2 is integrated with: a main control module 5, a multi-protocol PHY module 6, a security encryption module 7, an edge computing module 8, a dynamic power module 9, a self-restart module 10, and an extended communication module 19. Among them, the main control module 5 is used for system core scheduling and protocol processing, based on the Rockchip RK3568 quad-core processor with a main frequency of 2.0 GHz, running the OpenWRT system, built-in dynamic protocol adaptation engine, and using the signature weighted matching algorithm to identify the traffic type in real time;

[0045] The multi-protocol PHY module 6 is used for physical layer signal conversion and protocol adaptation, integrating the Marvell88E6390X chipset and the ADuM4160 isolator, automatically matching multiple industrial device interfaces through an impedance detection circuit. When detecting the 120Ω impedance of the RS485 interface, enable the ±15kV ESD protection circuit to ensure stable transmission under the 2500Vrms isolation withstand voltage in the industrial field;

[0046] The extended communication module 19 is used for wireless and cellular network access, supporting hot-swappable MiniPCIe interfaces;

[0047] The security encryption module 7 is used for data encryption and trusted verification. It is equipped with a GD32E508 national encryption chip and adopts a dynamic key generation mechanism. Each data packet has an independent encryption key. Combined with the SM4-CTR mode, it achieves an encryption throughput of 2.47 Gbps.

[0048] The edge computing module 8 is used for local data processing and intelligent decision-making. It is equipped with a Kendryte K510 AI processor. By expanding the RVV instruction set to add WASM-specific instructions, the inference speed of the MobileNetV2 model is improved. At the same time, 4 groups of 32KB VIPT Cache are used to optimize memory access, and the computing energy efficiency ratio is improved.

[0049] The dynamic power module 9 is used for intelligent energy consumption management. Based on the TI TPS652190 chip, it implements a three-stage energy-saving strategy:

[0050] When the load is less than 20%, the PCIe expansion slot is turned off and the DDR4 sleep mode is enabled. When the load is between 20% and 60%, the CPU voltage and frequency are dynamically adjusted. When the load is greater than 60%, the over-temperature protection circuit is activated. Combined with the PID control algorithm, the energy consumption fluctuation of the whole machine is reduced.

[0051] The self-restart module 10 is used for device self-healing in case of anomalies. The self-restart module 10 includes a status monitoring sub-module 11, a threshold judgment sub-module 12, and a progressive restart sub-module 13. The status monitoring sub-module 11 runs independently using the APM32F103 MCU and continuously collects the memory leak rate (ΔMem is the memory change amount within 5 minutes, unit: MB, Δt = 300 s), TCP retransmission rate (N retrans is the number of retransmitted packets, N total is the total number of sent packets), CPU soft error count is E soft and other multiple indicators. The data sampling interval is 100 ms, and it is uploaded to the main control module 5 in real time through the SPI bus. The threshold judgment sub-module 12 analyzes the monitoring data based on a multi-parameter fusion model. The model is: where 0.1, 0.3, and 0.6 are weight coefficients, determined by Monte Carlo simulation optimization. When F > 1.5 is satisfied for 3 consecutive monitoring cycles, the system is determined to be abnormal and a restart decision is triggered. Each cycle is 5 minutes. When the comprehensive indicators of memory leak rate, network retransmission rate, and CPU soft errors exceed the preset threshold, a restart decision is triggered. The progressive restart sub-module 13 is used to only back up the changed NAT session table, generates incremental data using the CRC32 checksum algorithm, stores it in the NOR Flash. The model of the NOR Flash is Winbond W25Q256JV, and the writing speed is 80 MB / s. Then it is reset in stages. The specific stages are:

[0052] Service layer shutdown: Terminate non-core services in order of priority, in the order of QoS → protocol conversion → edge computing;

[0053] Driver layer reset: Reset the wireless module, switch chip, and main control in sequence through the MAX6374 hardware watchdog. The reset interval is 50ms each time. The wireless module belongs to the extended communication module 19. Resetting the wireless module is used to reset the wireless communication unit to solve problems such as signal packet loss and channel congestion. The switch chip belongs to the multi-protocol PHY module 6. Resetting the switch chip is used to restore the network switching function and clear abnormalities such as MAC address table disorder. The main control belongs to the main control module 5. Soft resetting the main control is used to restart the key services of the Linux system and retain the memory data;

[0054] Status recovery: Read the session table from the NOR Flash and reconstruct the NAT mapping relationship.

[0055] As Figures 1-2 、 Figures 4-6 、 Figure 8 As shown, suction cups 3 are symmetrically arranged at the four corners of the bottom of the router housing 1, and heat dissipation grooves 4 are arranged on the side wall of the router housing 1. To facilitate releasing the adsorption effect of the suction cups 3, cylinders 16 corresponding to the suction cups 3 are penetrated and arranged at the four corners of the bottom of the router housing 1. A lifting cylinder 14 is vertically movably arranged inside the cylinder 16. The suction cup 3 is communicated and arranged at the bottom of the lifting cylinder 14. A ventilation pipe 18 corresponding to the lifting cylinder 14 is vertically fixed inside the router housing 1. The lifting cylinder 14 is movably sleeved outside the ventilation pipe 18. A sealing plug 21 for blocking the bottom of the lifting cylinder 14 is vertically movably arranged at the bottom of the lifting cylinder 14. Ventilation grooves 15 are arranged on the side walls at the upper and lower ends of the ventilation pipe 18. A first elastic member 20 is arranged between the top of the lifting cylinder 14 and the inner wall of the router housing 1. The first elastic member 20 is preferably a spring, and the upper and lower ends of the first elastic member 20 are respectively fixed on the inner wall of the router housing 1 and the top wall of the lifting cylinder 14. A second elastic member 22 is arranged between the bottom of the sealing plug 21 and the inner wall of the suction cup 3. The second elastic member 22 is preferably a spring. To increase the stability of the lifting cylinder 14, a limiting slide bar 25 parallel to the axis of the ventilation pipe 18 is arranged on the side wall of the ventilation pipe 18, and a limiting slideway 23 corresponding to the limiting slide bar 25 is arranged on the inner wall of the lifting cylinder 14. The limiting slide bar 25 and the limiting slideway 23 are in sliding and guiding cooperation.

[0056] As Figures 5-9 As shown, in order to prevent the lifting cylinder 14 from resetting after pressing down the router housing 1, elastic arms 17 are arranged around the upper end of the lifting cylinder 14. A clamping block 24 is arranged inside the upper end of the elastic arm 17. The upper end of the clamping block 24 is a slope and the bottom is a plane. A locking ring 27 is fixedly arranged on the outer wall of the upper end of the ventilation pipe 18. The locking ring 27 is in an inverted cone shape. The clamping block 24 is used for clamping and cooperating with the top of the locking ring 27;

[0057] Further, as Figure 9 shown, in order to facilitate the re - adsorption of the suction cup 3, an unlocking ring 26 is movably sleeved on the upper end of the air vent pipe 18. The unlocking ring 26 is conical and located above the locking ring 27, and the outer diameter of the unlocking ring 26 is not less than the outer diameter of the locking ring 27. A groove 30 corresponding to the unlocking ring 26 is provided on the side wall of the upper end of the air vent pipe 18. A protrusion 28 that is slidably matched with the groove 30 is provided on the inner wall of the unlocking ring 26. A third elastic member 29 is provided between the bottom of the protrusion 28 and the inner bottom of the groove 30. The third elastic member 29 is preferably a spring, and the third elastic member 29 is vertically arranged.

[0058] During use, the dynamic power module 9 first completes the power - on timing control to provide stable power supply for each module. Then the main control module 5 is started, loads the customized OpenWRT system and initializes the dynamic protocol adaptation engine, identifies the traffic type through the signature weighting algorithm. The multi - protocol PHY module 6 synchronously detects the physical interface impedance. When the RJ45 detects a 100Ω impedance, the gigabit Ethernet mode is activated. The RS485 interface enables ±15kV ESD protection. The extended communication module 19 initializes the Wi - Fi / 5G wireless connection and interacts with the main control through the PCIe interface. The security encryption module 7 generates dynamic keys for each packet of the transmitted data. The encryption throughput of the SM4 - CTR mode reaches 2.47Gbps. The edge computing module 8 receives the pre - processed data, accelerates the WASM instructions through the RISC - V NPU, and the result is routed and forwarded by the main control module 5. The dynamic power module 9 monitors the load in real - time. If the self - restart module 10 detects a fault, it resets the wireless module, the switching chip and the main control service in sequence, restores the NAT session with the differential snapshot, and forms a closed - loop self - healing system.

[0059] The usage principles of the suction cup 3, the pressing and desorbing component, the clamping component and the unlocking component are as follows:

[0060] Initially, the suction cup 3 adsorbs on the horizontal plane, and the sealing plug 21 plugs the bottom of the lifting cylinder 14. Both the first elastic member 20 and the second elastic member 22 are in the reset state or slightly contracted state. At this time, the router housing 1 can maintain stability and resist a certain degree of external force pulling. When it is necessary to separate the router housing 1 from the horizontal plane, press the router housing 1 downward. Then, the router housing 1 drives the ventilation pipe 18 to move downward. The ventilation pipe 18 moves downward inside the lifting cylinder 14, and the first elastic member 20 contracts. As it moves downward, the lower end of the ventilation pipe 18 contacts the top of the sealing plug 21, and then presses down the sealing plug 21. The second elastic member 22 contracts, and the sealing plug 21 separates from the bottom of the lifting cylinder 14. The ventilation slot 15 at the lower end of the ventilation pipe 18 is immediately communicated with the suction cup 3. Since the upper end of the ventilation pipe 18 is also provided with a ventilation slot 15, the suction cup 3 can be communicated with the outside through the ventilation slot 15 on the ventilation pipe 18 and the heat dissipation slot 4 on the side wall of the router housing 1. Then, the suction cup 3 can be easily separated from the horizontal plane. To prevent the first elastic member 20 and the second elastic member 22 from resetting when picking up the router housing 1, when pressing, until the block 24 at the upper end of the elastic arm 17 passes through the locking ring 27, when passing through, the elastic arm 17 is squeezed by the locking ring 27 and undergoes a bending deformation. When the block 24 reaches the top of the locking ring 27, the elastic arm 17 resets, and the block 24 is stuck at the top of the locking ring 27. At this time, stop pressing further after hearing a click sound. At this time, when picking up the router housing 1, the first elastic member 20 and the second elastic member 22 will not reset. When it is necessary to adsorb the suction cup 3 on the horizontal plane again, attach the suction cup 3 to the horizontal plane and continue to press the router housing 1 downward. The ventilation pipe 18 continues to move downward until the unlocking ring 26 passes through the upper end of the elastic arm 17, and the block 24 comes to the upper end of the unlocking ring 26. Then, loosen the router housing 1, and the first elastic member 20 and the second elastic member 22 gradually reset. The block 24 drives the unlocking ring 26 to move downward, and the protrusion 28 compresses the third elastic member 29. When the unlocking ring 26 and the locking ring 27 are combined, the block 24 gradually separates from the unlocking ring 26. Since the unlocking ring 26 is conical and the locking ring 27 is inverted conical, under the guidance of the inclined surface at the upper end of the unlocking ring 26, the block 24 can be separated from the whole of the locking ring 27 and the unlocking ring 26 to achieve unlocking. Then, the third elastic member 29 drives the unlocking ring 26 to reset through the protrusion 28. The lower end of the ventilation pipe 18 disengages from the inner side of the upper end of the suction cup 3, and the sealing plug 21 plugs the bottom of the lifting cylinder 14 again until the first elastic member 20 resets. At this time, the suction cup 3 can adsorb on the horizontal plane. If the adsorption is unstable, the router housing 1 can be appropriately pressed downward again to make the suction cup 3 adsorb firmly, and this time when pressing down, the ventilation pipe 18 does not contact the sealing plug 21.

[0061] The technical scope of the present invention is not limited to the content described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical idea of the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
