Description

Technical Field

[0001] This utility model relates to the field of gateway detection equipment, and more specifically, to a detection circuit used in a gateway anti-tampering device. Background Technology

[0002] In existing gateways, the detection circuitry used to detect unauthorized disassembly includes a microprocessor, a distance transmitter, a communication module, a data bus, and wires. Because gateways are often attached to the top surface of the device with strong adhesive, the sensors won't trigger the microcontroller if no light is detected after installation. Therefore, light and distance sensors are used to detect whether the device has been removed. However, if someone maliciously inserts a card under the gateway beforehand to block the sensors and then removes the device, the disassembly may go undetected, rendering the monitoring meaningless and creating security risks.

[0003] There are currently no solutions on the market to address the aforementioned technical issues. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a detection circuit for a gateway anti-tampering device, which overcomes the shortcomings of the prior art. To achieve the above technical objective, the technical solution of this utility model is as follows:

[0005] A detection circuit used in a gateway anti-tampering device includes a microprocessor, a triaxial sensor, a distance transmitter, a communication module, and a data bus.

[0006] The triaxial sensor, distance transmitter, and communication module are bidirectionally connected to the microprocessor. The microprocessor communicates with the device controller via a data bus, and the communication module communicates with the server.

[0007] Preferably, the distance transmitter is a light distance sensor.

[0008] Preferably, the communication module is a 4G communication module, a 5G communication module, or a 4G / 5G shared communication module.

[0009] Preferably, the triaxial sensor, distance transmitter, and communication module are bidirectionally connected to the microprocessor via wires.

[0010] In one embodiment, the triaxial sensor, distance transmitter, and communication module are wirelessly connected to the microprocessor for bidirectional communication.

[0011] Preferably, the microprocessor output is connected to the data bus input, and the data bus output is connected to the device controller.

[0012] Preferably, the triaxial sensor is set to detect removal and trigger an alarm mechanism when the angle in any direction of the gateway exceeds 4°. Setting the angle of the triaxial sensor to trigger the alarm can be achieved using existing technology.

[0013] Preferably, the distance transmitter is a light distance sensor.

[0014] Preferably, the triaxial sensor is a LIS2DW12TR chip, and the microprocessor is a CH582F chip.

[0015] Preferably, pins 11 (INT1) and 12 (INT2) of the triaxial sensor are connected to pins 27 and 28 of the microprocessor 1, respectively. For specific implementation, please refer to the chip user manual.

[0016] The beneficial effects of this product are as follows: This product has a simple structure and is easy to operate. It develops a new detection mechanism that, in addition to detecting the current light source, can also detect removal actions; it can even detect and alarm when maliciously using a card to block the light and remove the gateway. Based on existing products, this product adds a three-axis sensor to achieve gateway angle detection. The three-axis sensor monitors the gateway's installation status in real time. When the gateway's angle in any direction exceeds 4°, it is judged as removal, triggering the alarm mechanism. This product can achieve an accuracy rate of over 95% in detecting malicious gateway removal. Attached Figure Description

[0019] Figure 2 This is a schematic diagram of the structure of the LIS2DW12TR chip.

[0020] Figure 3 This is a schematic diagram of the CH582F chip. Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] like Figure 1-3 As shown, in order to facilitate understanding of the above technical solution of this utility model, the above technical solution of this utility model will be described in detail below through specific usage methods.

[0023] The detection circuit for preventing gateway tampering includes a microprocessor 1, a triaxial sensor 2, a distance transmitter 3, a communication module 4, and a data bus 5.

[0024] The triaxial sensor 2, distance transmitter 3, and communication module 4 are bidirectionally connected to the microprocessor 1. The microprocessor 1 communicates with the device controller via the data bus 5, and the communication module 4 communicates with the server.

[0025] In one embodiment, the distance transmitter 3 is preferably a light distance sensor.

[0026] In one embodiment, the communication module 4 is preferably a 4G communication module, or a 5G communication module, or a 4G / 5G shared communication module.

[0027] In one embodiment, the triaxial sensor 2, the distance transmitter 3, and the communication module 4 are bidirectionally connected to the microprocessor 1 via wires 6.

[0028] In one embodiment, the triaxial sensor 2, the distance transmitter 3, and the communication module 4 are connected to the microprocessor 1 via wireless bidirectional communication.

[0029] In one embodiment, the output of microprocessor 1 is connected to the input of data bus 5, and the output of data bus 5 is connected to the device controller.

[0030] In one embodiment, the triaxial sensor 2 is configured to detect a removal attempt and trigger an alarm mechanism when the angle in any direction of the gateway exceeds 4°. Setting the angle of the triaxial sensor 2 to trigger the alarm can be achieved using existing technology.

[0031] In one embodiment, the distance transmitter 3 is preferably a light distance sensor.

[0032] In one embodiment, the triaxial sensor 2 is preferably a LIS2DW12TR chip, and the microprocessor 1 is preferably a CH582F chip.

[0033] In one embodiment, pins 11 (INT1) and 12 (INT2) of the triaxial sensor 2 are preferably connected to pins 27 and 28 of the microprocessor 1, respectively. For specific implementation, please refer to the chip user manual.

[0034] Working Principle: Microcontroller 1 – Controls and acquires sensor data, collects device data, and transmits data to the Internet via mobile network. Triaxial Sensor 2 – Senses the three-axis acceleration components in its own Cartesian coordinate system and converts them into data. Distance Sensor 3 – Detects whether the current line intensity exceeds a set threshold; if so, it sends a signal and measures the distance between the sensor and the object in front. Communication Module 4 – Provides data communication capabilities via the operator's wireless network, enabling the microcontroller to send and receive data. Communication Bus 5 – The microcontroller acquires internal data from the installed device controller.

[0035] The existing product (including microprocessor 1, distance transmitter 3, communication module 4, and data bus 5) is only equipped with distance sensor 3 (usually a light distance sensor). The gateway is attached to the top surface of the device with strong adhesive, so after installation, distance sensor 3 cannot detect light and will not trigger microcontroller 1. If a thin card is maliciously inserted before distance sensor 3, and the device is then disassembled, the removal behavior cannot be detected. Therefore, this product adds a triaxial sensor 2 to the existing product. Even if the light distance sensor 3 is blocked and no light enters, as long as the angle formed when the gateway is removed reaches 4° or more, the removal behavior will be detected, and a removal alarm information will be reported to the server through communication module 4.

[0036] In summary, this product employs the aforementioned unique design, featuring a simple structure and convenient operation. It utilizes a novel detection mechanism that, in addition to detecting current light intensity, can also detect removal actions; it can even detect and trigger alarms when maliciously blocking light with a card to remove the gateway. Building upon existing products, this product adds a three-axis sensor to detect the gateway's angle. The three-axis sensor monitors the gateway's installation status in real time; when the gateway's angle in any direction exceeds 4°, it is considered removed, triggering an alarm. This product achieves an accuracy rate of over 95% in detecting malicious gateway removal.
