[0029] In order to make the above objectives, features and advantages of the present application more apparent, more comprehensible and more understandable, the embodiment of the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments. Referring to Figure 1A The figure is a schematic diagram of an inverter provided by the embodiment of the present application.

[0030] The inverter provided by the embodiment of the present application comprises a controller 101, a communication interface 105 and a communication module 102.

[0031] The controller 101 is connected to the communication module 102 through a first serial bus, the communication module 102 is connected to the communication interface 105, and the communication interface 105 is used to connect a communication antenna 21. It should be understood that the communication interface 105 of the inverter 100 can be installed with the communication antenna 21, or can not be installed with the communication antenna 21.

[0032] The embodiment of the present application does not specifically limit the type of the communication module 102, for example, it can be a wireless communication module, such as connecting WiFi; or a mobile communication module, such as connecting 4G or 5G, etc.

[0033] The embodiment of the present application does not specifically limit the type of the first serial bus, which depends on the interface type and communication protocol between the communication module 102 and the controller 101, for example, the first serial bus can use a Universal Asynchronous Receiver / Transmitter (UART) bus.

[0034] The controller 101 is connected to the communication interface 105 through a second serial bus, and the communication interface 105 is used to connect a communication stick 22.

[0035] The embodiment of the present application does not specifically limit the type of the second serial bus, which depends on the interface type and communication protocol between the communication interface 105 and the controller 101, for example, the second serial bus can use an RS485 or RS232 bus.

[0036] The embodiment of the present application does not specifically limit the type of the communication stick, which can be connected to any type of communication stick, for example, the communication stick connected through the second interface is any one of the following types: 4G, 5G, WiFi or WiNet.

[0037] The inverter provided by the embodiment of the present application is provided with a communication interface and a communication module, and thus the inverter can select a communication interface to communicate through a communication antenna or select to communicate through a communication rod. In actual use, the inverter can be installed with an antenna, a communication rod or both, and the optional mode is flexible.

[0038] For example, when the inverter is applied to a household scenario, the antenna can be selected to be installed to save the cost of the communication rod. When the inverter is applied to a remote field, the antenna can not provide good signal quality, and thus the communication rod can be selected to improve the quality of the communication signal.

[0039] Referring to Figure 1B FIG. 4 is a schematic diagram of another inverter provided by the embodiment of the present application.

[0040] The inverter provided by the embodiment of the present application comprises a controller 101, a first interface 20, a second interface 10 and a communication module 102.

[0041] The controller 101 is connected to the communication module 102 through a first serial bus, the communication module 102 is connected to the first interface 20, and the first interface 20 is used to connect a communication antenna 21. It should be understood that the first interface 20 of the inverter 100 can be installed with the communication antenna 21 or can not be installed with the communication antenna 21.

[0042] The controller 101 is connected to the second interface 10 through a second serial bus, and the second interface 10 is used to connect a communication rod 22.

[0043] The embodiment of the present application does not specifically limit the type of the second serial bus, which depends on the type of the interface between the second interface 10 and the controller 101 and the communication protocol. For example, the second serial bus can use an RS485 or RS232 bus.

[0044] It should be understood that the second interface 10 of the inverter 100 can be connected to the communication rod 22 or can not be connected to the communication rod 22 in actual work. For example, when the second interface 10 is not connected to the communication rod 22, the inverter 100 can communicate through the communication antenna 21. For example, when the inverter 100 is installed with the communication rod 22 and the inverter 100 is not installed with the communication antenna 21, the inverter 100 can communicate through the communication rod 22.

[0045] Referring to Figure 2 FIG. 5 is a schematic diagram of still another inverter provided by the embodiment of the present application.

[0046] The inverter provided by the embodiment of the present application uses a wireless communication module, and a possible implementation manner is introduced by taking a WiFi module as an example, in which the communication antenna 21 is a WiFi antenna. The WiFi antenna is connected to the first interface 20.

[0047] like Figure 2 As shown, the inverter 100 can connect to a WiFi antenna via a WiFi module, thereby connecting to a remote cloud server. Furthermore, the inverter 100 can connect to a nearby terminal device via WiFi through the WiFi module, allowing data exchange between the terminal device and the inverter 100 through a client software APP.

[0048] This application does not specifically limit the type of controller. The following describes one implementation of the controller with reference to the accompanying drawings.

[0049] See Figure 3 This figure is a schematic diagram of another inverter provided in an embodiment of this application.

[0050] The inverter provided in this application embodiment includes a controller comprising a digital signal processor (DSP) and a communication unit. This application embodiment does not specifically limit the type of communication unit; for example, it can be an ARM communication unit. It should be understood that... Figure 3 The controller in this example consists of two parts, but they can also be combined into one, with the processor and communication unit integrated into the same chip.

[0051] The DSP is connected to the ARM communication unit via the Controller Area Network (CAN) bus. The ARM communication unit is connected to the WiFi module via the first serial bus UART. The ARM communication unit is connected to the second interface 10 via the second serial bus RS485.

[0052] The ARM communication unit can determine the communication mode between the inverter 100 and the outside world by detecting whether the second interface 10 is connected to the communication rod 22 and whether the first interface 20 is connected to the communication antenna 21. When the second interface 10 is connected to the communication rod 22, the communication rod 22 can be used first to achieve communication in order to improve the communication quality.

[0053] One specific implementation involves a controller that disconnects the communication module when the communication stick is connected to the second interface. For example, the ARM communication unit can disconnect from the WiFi module when it detects that the communication stick 22 is connected to the second interface 10. This application does not specifically limit the method by which the ARM communication unit disconnects from the WiFi module; for example, it can be disconnected by hardware or by signal enabling, i.e., blocking signal transmission between the ARM communication unit and the WiFi module.

[0054] Figure 3 Other parts and Figure 2 Same, see also Figure 2The description of the foregoing embodiments is not repeated here.

[0055] Referring to Figure 4 , the figure is another schematic diagram of the inverter provided by the embodiment of the application.

[0056] The inverter provided by the embodiment of the application, the communication antenna 21 is a cellular antenna. The cellular antenna is connected to the first interface 20, and the communication module is a mobile communication module. It should be understood that when the communication module is a mobile communication module, the communication module further includes a Bluetooth module, and the mobile communication module is used to communicate through a mobile network. The type of the mobile network is not specifically limited by the application, for example, the mobile network can be 4G or 5G to realize remote communication, and the Bluetooth module can realize near-end communication, for example, the terminal device can interact with the inverter 100 through the client software APP on the terminal device.

[0057] Figure 4 The difference between Figure 3 is that the type of the communication module built-in in the inverter 100 is different, and the other parts are the same. For the description of Figure 3 , it is not repeated here.

[0058] Referring to Figure 5 , the figure is a side view of the inverter provided by the embodiment of the application.

[0059] The cabinet body of the inverter provided by the embodiment of the application can be seen to include two interfaces, the first interface 20 and the second interface 10. The first interface 20 is used to connect the communication antenna. The second interface 10 is used to connect the communication rod.

[0060] Referring to Figure 6 , the figure is a front view of the inverter provided by the embodiment of the application.

[0061] The inverter provided by the embodiment of the application further includes a display screen 103. The display screen can be located on the inverter cabinet shell.

[0062] The display screen 103 is connected to a controller (not shown in the figure), and the controller is located in the cabinet of the inverter. When the second interface is connected to the communication rod, the controller displays the first information on the display screen, and when the first interface is connected to the communication antenna, the controller displays the second information on the display screen.

[0063] It should be understood that since the controller is connected to the first interface and the controller is connected to the second interface, the controller will push the communication mode of the inverter 100 to the display screen 103 for display. The embodiments of the present application do not specifically limit the specific display mode. For example, the display screen includes indicator lights, which can be used to display. When communicating through the communication stick, the first indicator light flashes. When the inverter communicates through the communication antenna, the second indicator light flashes. In addition, the display screen can also not display information through the indicator light, but directly display information, and indicate the communication mode through the information, so as to facilitate the user to know the communication mode.

[0064] It should be noted that the various embodiments described in the specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the embodiments can be mutually referred to.

[0065] The above description of the disclosed embodiments enables a person skilled in the art to implement or use the present application. Various modifications to the embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
