[0020] In order to make the objectives, technical solutions and advantages of the present disclosure more clearly understood, the present disclosure is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0022] Multi-protocol IoT gateways generally include communication protocols such as Bluetooth, ZigBee, LoRa, and Ethernet. With the popularization of 5G networks, gateway devices can introduce 5G technology to increase the number of access devices. How to ensure that each wireless protocol can still work normally after the introduction of 5G communication technology, and each IoT antenna does not interfere with each other, it is crucial to reasonably layout the antenna solution.

[0023] In view of this, the embodiment of the present disclosure provides an Internet of Things gateway, including: a main body, used to support the components of the Internet of Things gateway; a main control board, located inside the main body; and an antenna assembly, located inside the main body, and including a short-range communication antenna, a 5G antenna assembly and a Wi-Fi antenna assembly, wherein the short-range communication antenna, the 5G antenna assembly and the Wi-Fi antenna assembly are respectively electrically coupled to the terminals of the corresponding communication modules on the main control board; wherein the short-range communication antenna, the main control board and the Wi-Fi antenna assembly are sequentially arranged inside the main body along the first direction of the main body; the length direction of the main control board is parallel to the first direction of the main body; and the 5G antenna assembly includes at least one pair of two antennas arranged on both sides or on the same side of the main control board. . The Internet of Things gateway provided by the embodiment of the present disclosure is suitable for multi-protocol Internet of Things gateway devices, and the mutual interference problem between multiple antennas of the multi-protocol Internet of Things gateway is avoided by reasonably arranging each antenna.

[0024] Figure 1A A schematic diagram of the structure of an exemplary Internet of Things gateway provided by an embodiment of the present disclosure is shown.

[0025] like Figure 1A As shown, the Internet of Things gateway 100 may include a main body 102, a main control board 104 and an antenna assembly. The main body 102 may be used to support the components of the Internet of Things gateway 100. In some embodiments, the main body 102 may further include a housing and a bracket, the bracket is arranged inside the housing, the bracket is used to realize the installation of the components of the gateway 100, and the housing is set outside the bracket and covers the components inside it. In some embodiments, the material of the main body 102 may be, for example, insulating ABS plastic, PLA plastic. In some embodiments, the Internet of Things gateway 100 may also include an infrared module 116, which is electrically coupled to the main control board 104 for infrared communication. In some embodiments, the Internet of Things gateway 100 may also include an Ethernet interface 118, which is electrically coupled to the main control board 104. The Ethernet interface 118 is used as a backup solution for the wireless module to deal with the situation where the wireless network is accidentally deteriorated and cannot access the Internet. In addition, in some embodiments, the Internet of Things gateway 100 may also include other types of interfaces, such as an RS232 interface (not shown), to adapt to other types of communication protocols.

[0026] The main control board 104 and the antenna assembly can be disposed inside the main body 102 (for example, can be disposed inside the housing of the main body 102). The main control board 104 can include a CPU and a memory. The main control board 104 coordinates the working process of each module and reasonably allocates CPU resources to ensure that each module works in an orderly manner. In addition, the main control board 104 can also be provided with communication modules corresponding to each antenna and terminals electrically coupled to each antenna.

[0027] like Figure 1A As shown, the antenna assembly may further include a short-range communication antenna and a long-range communication antenna. For example, the antenna assembly may include a LoRa antenna 106, a Wi-Fi antenna assembly 108, a Bluetooth (BT) antenna 110, a 5G antenna assembly 112, and a ZigBee antenna 114, etc. Among them, the LoRa antenna 106 and the ZigBee antenna 114 are short-range communication antennas, but it can be understood that the short-range communication antenna is not limited to the LoRa antenna 106 and the ZigBee antenna 114. For example, the short-range communication antenna may also be an Ultra Wide Band (UWB) antenna, a Narrow Band Internet of Things (NB-IoT) antenna, etc. Among them, the 5G antenna assembly 112 and the Wi-Fi antenna assembly 108 may correspond to the application scenario of high-frequency communication; the LoRa antenna 106, the ZigBee antenna 114, the infrared module 116, and the Bluetooth antenna 110 may correspond to the application scenario of low-frequency communication.

[0028] In some embodiments, a communication module corresponding to each antenna may be provided in the IoT gateway 100. For example, the communication modules of the LoRa antenna 106 and the 5G antenna assembly 112 may be provided on the main control board 104. The communication module may further include a chip and a peripheral circuit corresponding to the antenna, for example, the communication module of the LoRa antenna 106 may include a Semtech 1278 chip and a peripheral circuit.

[0029] Figure 1B FIG. 1 shows a schematic diagram of the circuit structure of an exemplary Internet of Things gateway provided by an embodiment of the present disclosure. Figure 1B As shown, each antenna in the antenna assembly can be electrically coupled to the main control board 104, so as to achieve electrical signal transmission with the main control board 104. In some embodiments, each antenna and infrared module in the antenna assembly can be in the form of a circuit module, and accordingly, an interface electrically coupled to each module can be reserved on the main control board 104.

[0030] like Figure 1AAs shown, along the first direction of the main body 102, the LoRa antenna 106, the main control board 104 and the Wi-Fi antenna assembly 108 can be sequentially arranged inside the main body 102. Assuming that the main body 102 of the Internet of Things gateway 100 is a cylinder, the first direction can be the height direction of the main body 102. Assuming that the main body 102 of the Internet of Things gateway 100 is a cuboid, the first direction can be the length direction of the main body 102.

[0031] Generally, the communication frequency of the LoRa antenna 106 is low frequency, which occupies a large space and has a strong anti-interference ability. Therefore, in some embodiments, the LoRa antenna 106 can be arranged at the end of the main body 102 along the first direction, such as Figure 1A As shown, taking the first direction as the vertical direction as an example, the LoRa antenna 106 can be set at the bottom of the main body 102. Since the LoRa antenna 106 has a strong anti-interference ability, being set at the bottom of the main body 102 has a weaker effect on its signal. In some embodiments, the ground wire of the LoRa antenna 106 can be grounded through the metal shell of the main body 102, thereby improving the antenna efficiency of the LoRa antenna 106. At the same time, since the LoRa antenna 106 is set at the bottom of the main body 102, the LoRa antenna 106 is more convenient to ground.

[0032] Generally, the main control board 104 is relatively large in size. Therefore, in order to achieve a reasonable layout, Figure 1A As shown, the main control board 104 can be arranged in the center of the main body 102, so that the space around the main control board 104 can be used to arrange various antennas and other modules.

[0033] In some embodiments, Figure 1A and Figure 2A As shown, the length direction of the main control board 104 may be parallel to the first direction of the main body 102 , and the thickness direction of the main control board 104 may be parallel to the second direction of the main body 102 .

[0034] In some embodiments, Figure 1A As shown, taking the first direction as the vertical direction as an example, the Wi-Fi antenna assembly 108 can be arranged on the upper part of the main body 102 and above the main control board 104. Generally, the communication frequency of the Wi-Fi antenna assembly 108 is relatively high, so its anti-interference ability is relatively weak, and it is necessary to prevent other objects from blocking its signal. In this embodiment, the Wi-Fi antenna assembly 108 is arranged above the main control board 104 to prevent the main control board 104 from blocking its signal. In some embodiments, the Wi-Fi antenna assembly 108 may include a Wi-Fi antenna module and a Wi-Fi antenna. The Wi-Fi antenna is attached to the Wi-Fi antenna module, and the attachment position can be selected according to actual needs.

[0035] In some embodiments, Figure 1A As shown, inside the main body 102, along the first direction, the LoRa antenna 106, the 5G antenna assembly 112 and the Wi-Fi antenna assembly 108 are sequentially arranged, wherein the position of the Wi-Fi antenna needs to be higher than the 5G antenna assembly 112. Therefore, when attaching the Wi-Fi antenna to the Wi-Fi antenna module, the position of the Wi-Fi antenna needs to be considered, so that its attachment position is higher than the 5G antenna assembly 112, for example, near the top of the Wi-Fi antenna assembly 108. In some embodiments, the orthographic projections of the LoRa antenna 106, the 5G antenna and the Wi-Fi antenna in the first direction may overlap or partially overlap, which is conducive to improving the structural compactness of the Internet of Things gateway 100.

[0036] In some embodiments, the number of Wi-Fi antennas in the Wi-Fi antenna assembly 108 may be more than one, for example, two. In this way, the two Wi-Fi antennas may be symmetrically arranged on both sides of the Wi-Fi antenna assembly 108. By providing two Wi-Fi antennas, it is helpful to improve signal strength, increase signal transmission direction, and expand transmission range.

[0037] In some embodiments, Figure 1A As shown, the 5G antenna assembly 112 may include at least one pair of two 5G antennas (e.g., 5G main antennas) disposed on both sides or on the same side of the main control board 104. When the two 5G antennas are disposed on the same side of the main control board 104, in order to improve the compactness of the structure, the two 5G antennas may be rotationally symmetrically distributed. When the two 5G antennas are disposed on both sides of the main control board 104, in order to improve the compactness of the structure, for example, the two 5G antennas may be symmetrically disposed on both sides of the main control board 104, and the two 5G antennas may be arranged along the thickness direction of the main control board 104 (e.g., Figure 2A The 5G antennas are arranged as shown in the figure, that is, a group of 5G antennas are respectively arranged on the outside of the two largest surfaces of the main control board 104. Because the 5G antenna occupies a large volume as a whole, and the space outside the two largest surfaces of the main control board 104 is also large, the 5G antenna is arranged on the outside of the two largest surfaces of the main control board 104, which can save the internal layout space of the Internet of Things gateway 100. In some embodiments, heat dissipation materials can be arranged on the side of the main control board 104, so that the heat generated by the 5G antenna can be dissipated as soon as possible.

[0038] In some embodiments, the 5G antenna assembly 112 is not directly disposed on the main control board 104, but is disposed on a bracket of the main body 102. For example, the main control board 104 is disposed inside the bracket, and the 5G antenna assembly 112 is disposed outside the bracket, thereby preventing the heat emitted by the 5G antenna from affecting the operation of the main control board 104, and also facilitating the improvement of the stability of the 5G antenna.

[0039] In some embodiments, Figure 1A As shown, the 5G antenna assembly 112 may further include two pairs of four antennas located on both sides or the same side of the main control board 104. By setting up paired 5G antennas, it is beneficial to improve signal strength, increase signal transmission direction, and expand transmission range.

[0040] For example, the 5G antenna assembly 112 may include a 5G main antenna assembly and a 5G auxiliary antenna assembly. The 5G main antenna assembly may include two 5G main antennas 1122 located on brackets on both sides or on the same side of the main control board 104, and the 5G auxiliary antenna assembly may include two 5G auxiliary antennas 1124 located on brackets on both sides or on the same side of the main control board 104. Figure 1A As shown, the 5G main antenna assembly and the 5G auxiliary antenna assembly can be arranged in sequence along the first direction of the main body 102. Among them, the communication frequency range of the 5G main antenna 1122 can be 700MHz~3GHz, and the communication frequency range of the 5G auxiliary antenna 1124 can be 3GHz~6GHz. It can be seen that the communication frequency of the 5G main antenna 1122 is low, while the communication frequency of the 5G auxiliary antenna 1124 is high. Correspondingly, the anti-interference energy of the 5G main antenna 1122 is strong, and the anti-interference energy of the 5G auxiliary antenna 1124 is weak. Correspondingly, the 5G main antenna 1122 is large in size, and the 5G auxiliary antenna 1124 is small in size.

[0041] In some embodiments, two 5G main antennas 1122 may be symmetrically arranged on both sides of the main control board 104. In this way, since the 5G main antenna 1122 is relatively large, the outer space of the two largest surfaces of the main control board 104 can be well utilized. At the same time, since the 5G main antenna 1122 has a strong anti-interference ability, it is arranged on both sides of the main control board 104, and the main control board 104 has less obstruction to its signal. For example, the signal emitted by the 5G main antenna 1122 can bypass the main control board 104 and be emitted outward.

[0042] Since the 5G auxiliary antenna 1124 has a weak anti-interference capability, in order to ensure that its signal is not blocked by the main control board 104, such as Figure 2B As shown, two 5G auxiliary antennas 1124 can be symmetrically arranged on both sides of the virtual extension portion 1042 of the main control board 104, and the virtual extension portion 1042 is an extension portion that can be formed by assuming that the main control board 104 extends along its length direction. Figure 1A As shown, the Wi-Fi antenna assembly 108 can be set between the two 5G auxiliary antennas 1124.

[0043] In some embodiments, Figure 1AAs shown, in order to improve compactness, the Bluetooth antenna 110 and the Wi-Fi antenna assembly 108 can be integrated into one, for example, the Bluetooth antenna 110 can be attached to the Wi-Fi antenna module. In some embodiments, the module of the ZigBee antenna 114 and the infrared module 116 can also be integrated into one.

[0044] In some embodiments, the ZigBee antenna 114 and the infrared module 116 may be arranged on a side of the Wi-Fi antenna assembly 108 away from the main control board 104. For example, taking the first direction as the vertical direction, the ZigBee antenna 114 and the infrared module 116 may be arranged on the top of the main body 102. In some embodiments, the length direction of the ZigBee antenna 114 and the infrared module 116 may be parallel to the second direction of the main body 102. In this way, the larger ZigBee antenna 114 and the infrared module 116 are arranged horizontally on the top of the main body 102, which can reduce the obstruction of the ZigBee antenna 114 and the infrared module 116 to other antenna layouts.

[0045] In some embodiments, the antenna types of adjacent antennas may be different, thereby reducing signal interference between adjacent antennas.

[0046] For example, Figure 2C As shown, the antenna form of the LoRa antenna 106 can be a loop antenna form, which includes a radiator 1062 and a ground wire 1064.

[0047] For example, Figure 2D As shown, the antenna form of the Wi-Fi antenna of the Wi-Fi antenna assembly 108 can be a dipole antenna form. It includes a first radiator 1082, a second radiator 1084 and a ground line 1086. The first radiator 1082 is a 2.4 GHz frequency band antenna, and the second radiator 1084 is a 5 GHz frequency band antenna. Similarly, the Bluetooth antenna 110 can also be a dipole antenna form.

[0048] For example, Figure 2E As shown, the antenna form of the 5G main antenna 1122 can be a dipole antenna form, which includes a radiator 11222 and a ground line 11224. Figure 2F As shown, the antenna form of the 5G main antenna 1122 can also be a planar inverted F antenna (PIFA). In some embodiments, the antenna form of the 5G auxiliary antenna 1124 can be a loop antenna.

[0049] For example, Figure 2G A schematic diagram of a top view of an exemplary ZigBee antenna according to an embodiment of the present disclosure is shown (with Figure 1AThe ZigBee antenna 114 may be a planar inverted F antenna (PIFA), which includes an L-shaped radiator 1142 and a ground line 1144 .

[0050] It can be understood that the antenna forms adopted by the above-mentioned antennas are only exemplary. On the premise of meeting the inventive concept of this embodiment, the antenna form of each antenna can be changed and is not limited to the antenna form given in the above-mentioned embodiment.

[0051] In some embodiments, in order to reduce signal interference between antennas, the antennas may meet certain distance requirements.

[0052] For example, along the first direction, the edge-to-edge distance range between the 5G auxiliary antenna 1124 and the 5G main antenna 1122 can be 30 to 50 mm, the edge-to-edge distance range between the 5G main antenna 1122 and the LoRa antenna 106 can be greater than 70 mm, and the edge-to-edge distance range between the Wi-Fi antenna of the Wi-Fi antenna assembly 108 and the 5G auxiliary antenna 1124 can be 15 to 30 mm.

[0053] For example, along the thickness direction of the main control board 104 (the second direction of the main body 102), the edge-to-edge distance range between the Wi-Fi antenna of the Wi-Fi antenna assembly 108 and the 5G auxiliary antenna 1124 can be 15 to 30 mm, and the edge-to-edge distance range between the 5G main antenna 1122 and the main control board 104 can be greater than 30 mm.

[0054] For another example, along the first direction, the edge-to-edge distance between the infrared module 116 and the Wi-Fi antenna of the Wi-Fi antenna assembly 108 may be in the range of 30 to 50 mm.

[0055] It should be noted that the edge-to-edge distance may refer to the shortest distance between the edges of two modules closest to each other. It is understandable that the distance ranges between the above modules are only exemplary, and the distance ranges between the modules may be changed on the premise of meeting the inventive concept of this embodiment, and are not limited to the ranges given in the above embodiments.

Based on the concept of the present disclosure, the technical features in the above embodiments or different embodiments may be combined, the steps may be implemented in any order, and there are many other variations of the different aspects of the present disclosure as described above, which are not provided in detail for the sake of simplicity.

[0057] In addition, to simplify the description and discussion, and in order not to obscure the present disclosure, known power / ground connections to integrated circuit (IC) chips and other components may or may not be shown in the provided figures. In addition, the devices may be shown in the form of block diagrams to avoid obscuring the present disclosure, and this also takes into account the fact that the details of the implementation of these block diagram devices are highly dependent on the platform on which the present disclosure will be implemented (i.e., these details should be fully within the scope of understanding of those skilled in the art).

Therefore, these descriptions should be considered illustrative rather than restrictive.

[0058] Although the present disclosure has been described in conjunction with specific embodiments of the present disclosure, many replacements, modifications and variations of these embodiments will be apparent to those skilled in the art from the foregoing description.
