Description

Technical Field

[0001] This invention relates to the field of gateway technology, and more particularly to a rapidly assembled integrated gateway. Background Technology

[0002] A gateway is a device that performs protocol conversion between different networks. This primarily refers to protocol conversion above the transport layer. It's used for interconnecting different networks. Different networks may use different protocols, requiring protocol conversion for them to communicate with each other.

[0003] Current IoT gateways generally possess certain network security protection capabilities, such as firewalls and intrusion detection, to prevent control and intrusion from the network. However, their physical security layer has significant shortcomings. To facilitate research and development, testing, and production debugging, gateway motherboards typically have physical debugging interfaces such as USB, UART, and JTAG. These interfaces often lack effective physical protection mechanisms in mass-produced devices. When the device is maliciously physically accessed, attackers can easily connect to the device's core using these exposed debugging interfaces.

[0004] This can lead to two serious security risks: First, directly extracting device firmware to analyze and steal sensitive information such as core algorithms and encryption keys; second, tampering with and flashing malicious firmware to implant backdoor programs, thereby gaining complete control over the gateway and its connected IoT devices. This "physical contact attack" can bypass most complex network security protection measures, leading to data leaks, device malfunctions, and even larger-scale network attacks, constituting a hidden and high-risk security vulnerability in the IoT system. Based on this, a rapidly assembled integrated gateway is proposed. Summary of the Invention

[0005] The purpose of this invention is to solve the problems in the prior art by proposing a rapidly assembled integrated gateway.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A rapid-assembly integrated gateway includes an assembly box and a packaging cover. A control motherboard is mounted on the inner end face of the assembly box. A power interface, a network interface, and multiple test interfaces are mounted on the side wall of the assembly box. The network interface and multiple test interfaces are all connected to conversion guide plates. The conversion guide plates are electrically connected to the control motherboard through electrical components. A through slot is opened at the bottom of each test interface. A blocking component for blocking external access is installed in the through slot. Multiple storage slots are opened on the side wall of the assembly box below the multiple test interfaces. A monitoring power supply is fixedly installed in the storage slots. The monitoring power supply is connected to two adjustment electromagnetic plates for adjusting the insertable state of the test interface. A monitoring component for monitoring the test interface for external physical attacks is arranged between the two adjustment electromagnetic plates. The electrical component includes a strip line, a flip shaft is provided on the outer side of the strip line, an electric push rod is provided on the side of the flip shaft for adjusting the deflection of the flip shaft, and a chain break assembly for protecting the gateway is connected to the end of the flip shaft.

[0007] Preferably, the assembly box is fixedly assembled with the packaging cover plate by multiple long screws, and the power interface is electrically connected to the power controller inside the assembly box.

[0008] Preferably, the electrical component includes a combination plug fixed to the end of the strip line, a combination slot fixed on the control board, and a plurality of plug interfaces adapted to the combination plug in the combination slot, and the strip line is electrically connected to the conversion guide plate.

[0009] Preferably, the blocking assembly includes a pin rotatably disposed in the through groove of the test interface, with torsion springs sleeved on the outer walls of both ends of the pin, and a blocking plate for blocking external intrusion is fixedly connected to the pin.

[0010] Preferably, the bottom of the baffle plate is fixedly connected to two symmetrically arranged adjusting magnetic columns, and a trigger head fixedly connected to the baffle plate is provided between the two adjusting magnetic columns. The positions of the adjusting magnetic columns correspond to those of the adjusting electromagnetic plate.

[0011] Preferably, the monitoring component includes a storage telescopic column fixed to the inner end face of the assembly box storage slot, the monitoring power supply is electrically connected to two adjustment electromagnetic plates, the monitoring power supply is electrically connected to the storage telescopic column, and a pressure sensor is fixedly connected to the top of the storage telescopic column.

[0012] Preferably, the inner end face of the assembly box is rotatably connected to the flipping shaft via a fixing plate, and an adjustment knob is fixedly connected to the outer wall of the end of the flipping shaft. The adjustment knob is set in an inclined state, and the piston rod end of the electric push rod is opposite to the inclined surface of the adjustment knob.

[0013] Preferably, the chain breaking assembly includes a flipping frame plate fixedly connected to the flipping shaft, and two flipping frame plates located on both sides of the strip line are fixedly connected by two chain breaking rollers. The two chain breaking rollers are located below and above the strip line, respectively, and two adjacent flipping frame plates are fixedly connected by a crossbar coaxial with the flipping shaft.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This solution, through the setting of blocking components, can actively detect any physical behavior attempting to insert into the test interface using movable blocking plates and pressure sensors, thus deterring intruders. At the same time, once an intrusion is detected, the system will immediately send an alarm to the user's mobile device. This allows users to grasp the physical security status of the IoT gateway in real time, even if they are thousands of miles away, achieving 24 / 7 remote monitoring.

[0015] 2. This solution, by adjusting the settings of the electromagnetic plate, can create a physical obstacle using the barrier to deal with intruders and trigger an alarm. For authorized users, it can be controlled remotely via a mobile app to grant temporary access to the test interface. The system will remove the protection by adjusting the electromagnetic plate to attract the barrier and retract the pressure sensor, ensuring that normal maintenance work is not affected and avoiding the impact of safety measures on ease of use.

[0016] 3. This solution, through the setting of the chain disconnect component, can automatically activate the mechanism to disconnect the external connection after detecting an intrusion. Through the electric push rod and the chain disconnect roller mechanism, the circuit connection between the internal control motherboard of the gateway and the external interface is physically pulled apart, fundamentally preventing attackers from extracting firmware or implanting backdoors through the interface, thus constructing a "monitoring-alarm-blocking" defense-in-depth closed loop.

[0022] Example, refer to Figures 1 to 9 A rapid-assembly integrated gateway includes an assembly box 1 and an encapsulation cover 2. A control motherboard 4 is mounted on the inner end face of the assembly box 1. A power interface 5, a network interface 7, and multiple test interfaces 6 are mounted on the side wall of the assembly box 1. The network interface 7 and multiple test interfaces 6 are all connected to a conversion guide plate 9. The conversion guide plate 9 is electrically connected to the control motherboard 4 through electrical components. A through slot is opened at the bottom of the test interface 6, and a blocking component for blocking external access is provided in the through slot. Furthermore, the assembly box 1 is fixedly assembled with the encapsulation cover plate 2 by multiple long screws 3, the power interface 5 is electrically connected to the power controller inside the assembly box 1, the electrical components include a combination plug 11 fixed on the end of the strip line 10, a combination slot 8 fixed on the control main board 4, the combination slot 8 is provided with multiple plug interfaces adapted to the combination plug 11, the strip line 10 is electrically connected to the conversion guide plate 9, the blocking component includes a pin 12 rotatably set in the through groove of the test interface 6, torsion springs 13 are sleeved on the outer walls of both ends of the pin 12, the pin 12 is fixedly connected to a blocking plate 14 for blocking external intrusion insertion, the bottom of the blocking plate 14 is fixedly connected to two symmetrically arranged adjusting magnetic pillars 15, a trigger head 16 fixedly connected to the blocking plate 14 is provided between the two adjusting magnetic pillars 15, and the position of the adjusting magnetic pillars 15 corresponds to that of the adjusting electromagnetic plate 18; It should be noted that when assembling and wiring the IoT gateway with the electrical equipment that needs to be connected to the network, during the use of the IoT gateway, both the network interface 7 and the test interface 6 are electrically connected to the strip line 10 through the conversion guide plate 9, and then electrically connected to the combination slot 8 on the control motherboard 4 through the combination plug 11 on the strip line 10, so as to realize the electrical connection between the various plugs on the outside of the gateway and the control motherboard 4 inside. This connection state will not be described in detail later. Under the normal use state of the IoT gateway, the pin 12 on the blocking plate 14 will drive the blocking plate 14 to maintain the initial state of upward tilt under the action of the torsion springs 13 at both ends. The upward tilting blocking plate 14 will block the insertion path of the test interface 6, so that external physical intrusion is blocked when inserting. The benefits mentioned above are: it facilitates the monitoring of the status changes of the blocking plate 14 in real time, and enables the IoT gateway to be monitored for external physical intrusion. This adds offline physical protection to the traditional network protection of the IoT gateway, ensuring the safe use of the IoT gateway and electrical equipment. Multiple storage slots are provided on the side wall of the assembly box 1 located below multiple test interfaces 6. A monitoring power supply 17 is fixedly installed in the storage slots. The monitoring power supply 17 is connected to two adjustment electromagnetic plates 18 for adjusting the insertable state of the test interface 6. A monitoring component for monitoring the test interface 6 under external physical attack is provided between the two adjustment electromagnetic plates 18. Furthermore, the monitoring component includes a storage telescopic column 20 fixed to the inner end face of the storage slot of the assembly box 1, a monitoring power supply 17 electrically connected to two adjusting electromagnetic plates 18, a monitoring power supply 17 electrically connected to the storage telescopic column 20, and a pressure sensor 19 fixedly connected to the top of the storage telescopic column 20. It should be noted that when the test plug 6 is subjected to external intrusion, the upwardly tilted blocking plate 14 will be pressed and deflected downward. The blocking plate 14 will then drive the trigger head 16 to deflect downward as well, causing the trigger head 16 to press against the pressure sensor 19 below. After sensing the pressure, the pressure sensor 19 will promptly feed back to the control system and issue an alarm. At the same time, the IoT gateway will also feed back this intrusion status to the user's mobile device, so that the user can be informed of the intrusion even when not near the IoT gateway and electrical equipment. If the user conducts the test and uses the test interface by himself, he can use the mobile device to control the monitoring power supply 17 to synchronously energize the adjusting electromagnetic plate 18 and the storage telescopic column 20. When the adjusting electromagnetic plate 18 is energized, it becomes magnetic and generates a magnetic attraction force on the two adjusting magnetic columns 15 at the bottom of the blocking plate 14, causing the blocking plate 14 to deflect downward on its own. At the same time, the storage telescopic column 20 will retract on its own after being energized, causing the pressure sensor 19 to move downward, so that the trigger head 16 does not come into contact with the pressure sensor 19 when it deflects downward, thus ensuring the autonomy and safety of the user's own use. The electrical components include a strip line 10, a flip shaft 21 is provided on the outer side of the strip line 10, an electric push rod 25 for adjusting the deflection of the flip shaft 21 is provided on the side of the flip shaft 21, and a chain break assembly for protecting the gateway is connected to the end of the flip shaft 21. Furthermore, the inner end face of the assembly box 1 is rotatably connected to the flip shaft 21 through a fixed plate. An adjustment knob 24 is fixedly connected to the outer wall of the end of the flip shaft 21. The adjustment knob 24 is set in an inclined state. The piston rod end of the electric push rod 25 is opposite to the inclined surface of the adjustment knob 24. The chain breaking assembly includes a flip frame plate 22 fixedly connected to the flip shaft 21. Two flip frame plates 22 located on both sides of the strip line 10 are fixedly connected through two chain breaking rollers 23. The two chain breaking rollers 23 are located below and above the strip line 10, respectively. Two adjacent flip frame plates 22 are fixedly connected through a crossbar coaxial with the flip shaft 21. It should be noted that after the pressure sensor 19 senses the pressure and provides feedback, the electric push rod 25 inside the assembly box 1 will be pushed forward under control. The electric push rod 25 will then push the downward tilting adjustment knob 24, causing the adjustment knob 24 to continuously deflect downward, which in turn drives the flip shaft 21 to deflect downward synchronously. After the flip shaft 21 deflects downward, it will drive the flip frame plate 22 and the broken chain roller 23 to deflect downward together. Under the control of the flip frame plate 22, the two broken chain rollers 23 deflect downward as a whole. The broken chain roller 23 located on the upper surface of the strip line 10 will press the strip line 10 downward, while the broken chain roller 23 located on the lower surface of the strip line 10 will flip upward when the flip frame plate 22 deflects downward as a whole. This will cause the broken chain roller 23 to push and pull the lower surface of the strip line 10 upward, causing the strip line 10 to be pulled and causing the combination plug 11 to disengage from the combination slot 8. The above benefits are as follows: it physically isolates the connection between the external power signal and the control motherboard 4, preventing intruders from directly extracting firmware and implanting backdoors through the interface, thus avoiding security issues in the use of IoT devices. In use, the present invention involves assembling and wiring the IoT gateway with the electrical equipment that needs to be connected to the network. During the use of the IoT gateway, both the network interface 7 and the test interface 6 are electrically connected to the strip line 10 through the conversion guide plate 9, and then electrically connected to the combination slot 8 on the control motherboard 4 through the combination plug 11 on the strip line 10. This realizes the electrical connection between the various plugs on the outside of the gateway and the control motherboard 4 inside. This connection state will not be described in detail later. Under normal use, the pin 12 on the blocking plate 14, under the action of the torsion springs 13 at both ends, will drive the blocking plate 14 to maintain the initial upward tilt. The upward tilting blocking plate 14 will block the insertion path of the test interface 6, thus preventing external physical intrusion during insertion. It also facilitates the real-time monitoring of the state changes of the blocking plate 14 to see if the IoT gateway has been subjected to external physical intrusion. This adds offline physical protection to the traditional network protection of the IoT gateway, ensuring the safety of the IoT gateway and electrical equipment. When the test plug 6 is subjected to external intrusion, the upwardly tilted blocking plate 14 will be pressed and deflected downward. The blocking plate 14 will then drive the trigger head 16 to deflect downward as well, causing the trigger head 16 to press against the pressure sensor 19 below. After sensing the pressure, the pressure sensor 19 will promptly feed back to the control system and issue an alarm. At the same time, the IoT gateway will also feed back this intrusion status to the user's mobile device, so that the user can be informed of the intrusion even when not near the IoT gateway and electrical equipment. If the user conducts the test and uses the test interface by himself, he can use the mobile device to control the monitoring power supply 17 to synchronously energize the adjusting electromagnetic plate 18 and the storage telescopic column 20. When the adjusting electromagnetic plate 18 is energized, it becomes magnetic and generates a magnetic attraction force on the two adjusting magnetic columns 15 at the bottom of the blocking plate 14, causing the blocking plate 14 to deflect downward on its own. At the same time, the storage telescopic column 20 will retract on its own after being energized, causing the pressure sensor 19 to move downward, so that the trigger head 16 does not come into contact with the pressure sensor 19 when it deflects downward, ensuring the autonomy and safety of the user's own use. After the pressure sensor 19 senses the pressure and provides feedback, the electric push rod 25 inside the assembly box 1 will be pushed forward under control. The electric push rod 25 will then push the downward tilting adjustment knob 24, causing the adjustment knob 24 to continuously deflect downwards. This, in turn, will drive the flip shaft 21 to deflect downwards synchronously. After the flip shaft 21 deflects downwards, it will drive the flip frame plate 22 and the chain break roller 23 to deflect downwards together. Under the control of the flip frame plate 22, the two chain break rollers 23 deflect downwards as a whole. The chain break roller 23 located on the upper surface of the strip line 10 below... The strip line 10 is pressed downwards, while the chain break roller 23 located on the lower surface of the strip line 10 flips upwards when the flip frame plate 22 is tilted downwards. This causes the chain break roller 23 to push and pull the lower surface of the strip line 10 upwards, causing the strip line 10 to be pulled and causing the combination plug 11 to separate from the combination slot 8. This physically isolates the connection between the external power signal and the control motherboard 4, preventing intruders from directly extracting firmware and implanting backdoors through the interface, thus avoiding security issues in the use of IoT devices.
