[0032] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0033] To ensure good anti-interference performance and better communication quality stability during use, such as Figure 1-6 As shown, the communication device based on the Internet of Things according to this utility model includes a housing 1, which has an isolation chamber 13 inside;

[0034] The main control module 15 is located in the center of the isolation chamber 13;

[0035] The communication module 17 and the power supply module 18 are symmetrically distributed on both sides of the main control module 15;

[0036] The anti-interference module includes an electromagnetic shielding layer 12 covering the isolation chamber 13, a signal filtering circuit 16 connected to the communication module 17, and a grounding terminal 8 in contact with the inner wall of the housing 1.

[0037] The main control module 15 is connected to the communication module 17 and the power module 18 via shielded wires;

[0038] The inner wall of the isolation chamber 13 is coated with a wave-absorbing material layer 14, and the electromagnetic shielding layer 12 and the wave-absorbing material layer 14 form a double-layer anti-interference structure.

[0039] In use, the electromagnetic shielding layer 12 and the wave-absorbing material layer 14 form a composite protection structure that combines physical isolation and energy absorption. This not only blocks the intrusion of external electromagnetic radiation but also absorbs stray electromagnetic waves generated by the internal modules, significantly improving the equipment's anti-electromagnetic interference capability.

[0040] For example, such as Figure 2 As shown, the present invention also includes an electromagnetic shielding layer 12 made of aluminum foil and a wave-absorbing material layer 14 made of polyurethane.

[0041] In use, the use of aluminum foil and polyurethane materials can effectively improve the electromagnetic shielding effect and electromagnetic wave absorption performance of the isolation chamber 13.

[0042] For example, such as Figure 5 As shown, the present invention also includes a signal filtering circuit 16 comprising a common-mode inductor 19 connected in series and a ceramic capacitor 20 connected in parallel to ground, wherein the input terminal of the common-mode inductor 19 is connected to the communication module 17.

[0043] When in use, the common-mode inductor 19 and the ceramic capacitor 20 form an LC composite filter network, which can effectively improve the filtering effect on the communication module 17.

[0044] For example, such as Figure 5 As shown, the present invention also includes a TVS diode array 21 connected in parallel with the common-mode inductor 19, which consists of 4-6 bidirectional transient suppression diodes.

[0045] When in use, the TVS diode array 21 forms a redundant protection structure through the parallel design of 4-6 bidirectional diodes, which can absorb surge power of up to several kilowatts.

[0046] For example, such as Figure 1 and 6 As shown, the present invention also includes a side cover 2 fastened to one side of the outer shell 1, and the inner surface of the side cover 2 is provided with ribs 22 spaced 8-15mm apart.

[0047] In use, the rib plate 22 can effectively improve the strength of the side cover 2, and the side cover 2 can be used to close one side of the outer shell 1 as needed.

[0048] For example, such as Figure 2As shown, the present invention also includes at least three sets of contact points 9, each of which is connected to the inner wall of the outer casing 1 by a conductive spring 10.

[0049] During use, the multi-point elastic contact structure ensures a continuous low-impedance connection between the grounding terminal and the inner wall of the housing, effectively compensating for contact degradation caused by housing deformation or vibration, and significantly improving electromagnetic interference discharge efficiency and long-term operational reliability of the equipment.

[0050] For example, such as Figure 2-3 As shown, the present invention also includes a bottom connection between the bottom of the isolation chamber 13 and the bottom of the outer shell 1 via a support column B11, and a support column A3 is provided at the bottom of the outer shell 1 near the corner.

[0051] In use, the isolation chamber 13 can be easily fixed to the bottom of the outer shell 1 using the support column B11, and the bottom of the outer shell 1 can be easily raised and protected using the support column A3.

[0052] For example, such as Figure 1-3 As shown, the present invention also includes a power supply cable routing groove A6 that runs through one end of the bottom of the outer shell 1, heat dissipation grooves 5 that run through both ends of the isolation chamber 13 and the outer shell 1, a power supply cable routing groove B7 that runs through the outer wall of the isolation chamber 13 near the bottom, and signal cable routing grooves 4 that run through the outer shell 1 and the isolation chamber 13 at the corresponding positions of the communication module 17.

[0053] During use, the power supply cable trays A6 and B7 facilitate the routing of external power supply lines to power the electrical structure within the isolation chamber 13. The heat dissipation tray 5 effectively improves the heat dissipation of the device, and the signal cable tray 4 facilitates the routing of signal transmission lines for the communication module 17.

[0054] In use, the external power supply line passes through power supply cable trays A6 and B7 to supply power to the electrical structure within the isolation chamber 13. The heat dissipation slot 5 effectively improves the heat dissipation of the device, and the signal cable tray 4 facilitates the routing of signal transmission lines for the communication module 17.

[0055] The electromagnetic shielding layer 12 and the absorbing material layer 14 form a composite protective structure that provides both physical isolation and energy absorption. This structure not only blocks external electromagnetic radiation but also absorbs stray electromagnetic waves generated by the internal modules, significantly improving the equipment's resistance to electromagnetic interference. Furthermore, the centrally located main control module 15 creates a symmetrical electromagnetic field distribution. Combined with the symmetrical layout of the communication module 17 and the power supply module 18, this effectively balances the internal electromagnetic field distribution, reduces cross-interference between modules, and further enhances the system's operational stability.

[0056] The filter circuit is directly connected to the output terminal of the communication module 17. It forms an LC composite filter network with the common mode inductor 19 and the ceramic capacitor 20, which can effectively improve the filtering effect of the communication module 17, thereby improving the anti-interference effect. This communication device has a good anti-interference effect and better communication quality stability during use.
