DETAILED DESCRIPTION

[0025] The following will be combined with the attached Figures 1 to 4 The technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] It should be noted that if the directions involved in the embodiments of the present invention are based on those shown in the drawings, if a certain posture changes, the directional indication will also change accordingly.

[0027] Ethernet is a computer local area network technology. Ethernet has been widely used in local area networks, including enterprise networks, home networks, data centers, etc. Therefore, most of the existing terminal devices can support Ethernet network technology for connection.

[0028] Although Ethernet is excellent, there are still some problems, such as the need for different devices to transmit in close distances, high power consumption, and relatively high requirements for connected devices and poor compatibility.

[0029] To this end, with the introduction of Wi-Fi HaLow network technology, Wi-Fi HaLow is the latest protocol based on IEEE 802.11MAC / PHY (media access control / physical layer) certified by the Wi-Fi Alliance. Wi-Fi HaLow combines IEEE802.11ah to achieve low-power connections required by various applications, including cameras, sensor networks and wearable devices.

[0030] Wi-Fi HaLow can provide all the Wi-Fi expectations of today's consumers, including multi-vendor interoperability, simple setup without interrupting existing Wi-Fi networks, and the latest Wi-Fi security of WPA3TM. Wi-Fi HaLow can enhance other Wi-Fi technologies, provide long-distance, low-power, high-performance and secure Wi-Fi, and has strong compatibility, which is welcomed by consumers. However, since most existing terminal devices can only support Ethernet network technology, Wi-Fi HaLow network technology has been slow to gain popularity.

[0031] In this regard, the inventors provide a network converter, the purpose of which is to convert one network protocol into another network protocol so that devices with different protocols can communicate with each other. In actual use, it is only necessary to connect the terminal device to the network converter to convert the Ethernet network used by the terminal device into a Wi-Fi HaLow network, so that the terminal device can communicate and transmit with different devices in the Wi-Fi HaLow network.

[0032] like Figure 1 As shown, a network converter of the present technical solution includes a housing 1 and an antenna 2, wherein the antenna 2 is detachably connected to the housing 1. Specifically, as Figure 2 As shown, one side of the housing 1 has an access portion 11, and the position where the antenna 2 matches the access portion 11 has an insertion portion 21, the access portion 11 is matched and assembled with the insertion portion 21, and the insertion portion 21 of the antenna 2 is inserted into the access portion 11, so that the antenna 2 and the housing 1 are detachably connected. Of course, this kind of detachable connection also includes a spiral connection, etc. In some other practical use scenarios, the antenna 2 and the housing 1 can also be fixedly connected.

[0033] It should also be noted that, whether the detachable connection or the fixed connection, both are electrical connections. Figure 3 As shown, the housing 1 has a circuit board A inside, and the antenna 2 is electrically connected to the circuit board A.

[0034] The housing 1 has an automatic conversion unit 12 inside, and the automatic conversion unit 12 is arranged in the circuit board A. Specifically, the automatic conversion unit 12 includes a Halow module 121, a conversion module 122 and an RJ45123 interface; it should be noted that the Halow module 121 and the conversion module 122 are respectively located in different areas on the circuit board A, the RJ45 is a network connection port for inserting an external terminal device, and the Halow module 121 forms a bidirectional transmission signal with the RJ45123 interface through the conversion module 122.

[0035] It should be understood that when in use, after the external terminal device is inserted into the RJ45123, it is electrically connected to the Halow module 121 and the conversion module 122.

[0036] In this embodiment, the RJ45 123 interface is rectangular, generally about 1 cm wide and 2 cm long, and has 8 metal contact pins arranged neatly inside the interface. The interface is usually used to connect Ethernet devices, such as computers, switches, etc., to realize the transmission, reception and processing of Ethernet signals. These are all existing technologies and will not be described in detail here.

[0037] The RJ45 123 interface is electrically connected to the conversion module 122, and the conversion module 122 is a W5500 chip, which is a cost-effective Ethernet chip. It has the following characteristics: it supports TCP, UDP, ICMP, IPv4, ARP, IGMP, PPPoE and other protocols, and the hardware protocol stack is not subject to network attacks, safe and stable; it provides a simple Internet connection solution for embedded systems, so that users can use a single chip to expand network connections in their applications. Its application areas include but are not limited to home network devices, serial to Ethernet devices, parallel to Ethernet devices, USB to Ethernet devices (such as storage devices, network printers, etc.), security systems (such as digital video recorders, network cameras, information kiosks, etc.) and factory and building automation control systems, medical monitoring equipment, embedded servers, etc. These are all existing technologies and will not be repeated here.

[0038] The conversion module 122 is electrically connected to the Halow module, and the Halow module 121 uses a HalowModule chip, which is connected to the conversion module 122, that is, connected to the W5500 chip. In actual use, the HalowModule chip has the function of protocol conversion or data conversion, so that the device using W5500 can communicate or work with other devices in the Wi-Fi HaLow network.

[0039] That is, it can be understood that when an external terminal device using Ethernet is inserted into the network converter through the RJ45123 interface, the conversion module 122 recognizes that the network protocol of the external terminal device is Ethernet, and transmits the network information to the Halow module. The Halow module receives the Ethernet and converts it into a HaLow protocol suitable for Wi-Fi HaLow, and sends the data information of the external terminal device from the antenna 2 to the next receiving device. It should be understood that the antenna 2 is connected to the Halow module 121, and the antenna 2 is used to receive or send Halow network data.

[0040] In another usage scenario, the Halow module 121 can also convert the data information sent by the device using Wi-Fi HaLow received by the antenna 2 into data information that can be recognized by the Ethernet device, and then convert it into qualified Ethernet data through the conversion module 122 and send it to the connected device through the RJ45123 interface.

[0041] In summary, a network converter of the present technical solution supports bidirectional transmission of information data between Ethernet network devices and Wi-Fi HaLow network devices.

[0042] Further, such as Figure 3 As shown, the housing 1 further includes a control unit 13, which is connected to the Halow module 121 and independently controls the opening or closing of the Halow module 121. The control unit 13 is embodied as a button on the outside of the housing 1, and the user can press the button to enable the Halow module 121 to turn on the Halow protocol conversion.

[0043] That is, it should be understood that when it is necessary to convert an Ethernet network device into a Wi-Fi HaLow network device, the button can be pressed to start the Halow module 121 to start the Halow protocol conversion; otherwise, it is not turned on, and the data information sent by the Ethernet network device will also be sent from the antenna 2 in a manner that can be recognized by the Ethernet network.

[0044] Furthermore, Figure 3 As shown, the housing 1 further includes a display unit 14 , which is connected to the Halow module 121 and is used to display the working status of the Halow module 121 .

[0045] It should be noted that the display unit 14 is an LED lamp or a light emitting diode. The display unit 14 is arranged on the connection lines of different modules, and the display unit 14 is partially exposed on the outer surface of the shell 1. In other usage scenarios, the display unit 14 is arranged inside the shell 1, but the light of the display unit 14 can be displayed through the shell 1 to facilitate the user to observe the working status of different modules.

[0046] Furthermore, Figure 3 As shown, the housing 1 further includes a reset unit 15, and the reset unit 15 is used to restore the network converter to an initial state.

[0047] Specifically, the reset unit 15 is partially exposed as a button on the surface of the housing 1, so that the user can press the button to restore the network converter to an initial state.

[0048] It should be noted that the reset unit 15 is provided on the connection line between the conversion module 122 and the Halow module 121 .

[0049] It should be understood that when, for example, the conversion between the Ethernet network and the Wi-Fi HaLow network is unsuccessful during use, the reset unit 15 can be pressed to restore the original network protocol of different devices.

[0050] Furthermore, Figure 3 As shown, the housing 1 further includes a power supply unit 16, which is used to connect an external power supply device to supply power to the network converter, so that different modules in the network converter can work normally.

[0051] In addition, if Figure 4 As shown, a network system is also proposed, including a mobile terminal device 100 and a network converter 200 as described above; the network converter 200 is used to connect to the mobile terminal device 100 to convert an Ethernet network into a Wi-Fi HaLow network.

[0052] Specifically, in this embodiment, for example, the mobile terminal device 100 is a laptop computer. When the network converter 200 is plugged into the laptop computer, the network converter 200 automatically converts the laptop computer using the Ethernet network into a laptop computer applicable to the Wi-Fi HaLow network. The laptop computer applicable to the Wi-Fi HaLow network is put into the Wi-Fi HaLow local area network for use, so that data interaction can be achieved with another device at a long distance.

[0053] According to the disclosure and teaching of the above description, the technical personnel in the field to which the utility model belongs can also change and modify the above implementation. Therefore, the utility model is not limited to the specific implementation methods disclosed and described above, and some modifications and changes to the utility model should also fall within the scope of protection of the claims of the utility model. In addition, although some specific terms are used in this specification, these terms are only for the convenience of description and do not constitute any limitation to the utility model.
