Accordingly, the devices provided in the embodiments of the present application may also realize these features or functions accordingly, which will not be elaborated here.

[0041] In this application, unless otherwise specified, the same or similar parts between the various embodiments can refer to each other. In the various embodiments in this application, and the various implementation methods in each embodiment, if there is no special description and logical conflict, the terms and / or descriptions between different embodiments and the various implementation methods in each embodiment are consistent and can be referenced to each other.

[0042] At present, with the rapid development of the photovoltaic field, the types of accessible devices supporting photovoltaic systems are increasing. Accessible devices can be connected to the photovoltaic system through an inverter to achieve data interaction and energy transmission. In related technologies, after the device is connected to the photovoltaic system, the operation and maintenance personnel need to set it up before the corresponding functions can be realized, which is time-consuming and labor-intensive.

[0043] To solve the above problems, the present application proposes a device management method, apparatus, device and storage medium. The device management method is applied to an inverter. The method includes: when the inverter detects that a device is connected to a port, the inverter identifies the device type of the connected device, and when the device type of the connected device is successfully identified, establishes a communication connection with the connected device. Furthermore, the inverter starts a function corresponding to the device type of the connected device.

[0044] In this way, when the inverter detects that there is a device connected to the port, it can automatically identify the connected device and establish a communication connection with the access device if the match is successful, so that the inverter and the access device form an integrated system. The inverter can transmit information to the access device and automatically start the function corresponding to the device type of the access device, thereby realizing plug-and-play of the access device.

[0045] Figure 1 A device management system is shown. The device management method provided in the embodiment of the present application can be applied to Figure 1 The device management system shown is used to realize plug-and-play of devices connected to the inverter, which is convenient for user operation. Figure 1 As shown, the device management system 10 includes an inverter 11 and an access device 12 .

[0046] Among them, the inverter 11 and the access device 12 are hardware-connected through a connecting line. The inverter 11 includes multiple ports for accessing other devices. The access device 12 can be exemplified by a cloud communication box, a battery pack, a smart junction box, a light-emitting diode (LED) display light, a liquid crystal display (LCD), a smart meter, etc.

[0047] It should be noted that the embodiment of the present application does not specifically limit the connection form of the hardware connection between the inverter 11 and the access device 12, such as the port type, port number, port communication number and port form of the inverter.

[0048] exist Figure 1 In the device management system 10 shown, the inverter 11 can determine whether a device is connected or removed by detecting the ports included therein.

[0049] The inverter 11 may also identify the access device 12 through the port to determine the device type of the access device.

[0050] Furthermore, the inverter 11 can also establish a communication connection with the access device 12 through a port to form an integrated system with the access device 12 .

[0051] The inverter 11 may also start a function corresponding to the device type of the access device 12 to achieve plug-and-play of the access device 12 .

[0052] In some embodiments, Figure 2 As shown, the device management method provided in the present application can be applied to an embedded operating system using an inverter as a hardware computing platform, and can work in coordination with a communication system (CMS), an energy management system (EMS), etc. in the device system.

[0053] Figure 3 is a flow chart of a device management method according to some exemplary embodiments. In some embodiments, the device management method can be applied to Figure 1 The inverter 11 in the device management system 10 is shown. In the following, the device management method is described by taking the application of the device management method to the inverter 11 as an example.

[0054] like Figure 3 As shown, the device management method provided in the embodiment of the present application includes the following S301-S303.

[0055] S301: When the inverter detects that a device is connected to a port, it identifies the type of the connected device.

[0056] As a possible implementation, the inverter detects multiple ports in real time and determines whether there is a device connected through port power supply and / or port contacts. Further, when it is detected that a device is connected to the port, the inverter identifies the device type of the connected device through the port.

[0057] In some embodiments, the inverter determines whether a device is connected by supplying power to the port. For example, the inverter determines whether a device is connected by detecting whether there is a voltage output change or a voltage input change at each port.

[0058] The inverter determines whether a device is connected through the port contacts. For example, the inverter determines whether a device is connected based on the voltage and current changes of the port contacts.

[0059] When it is detected that a device is connected to the port, the inverter identifies the device type of the connected device through the port. For example, the inverter sends multiple test signals to the connected device.

[0060] The multiple test signals include test signals corresponding to different device types.

[0061] It should be noted that different types of devices are configured with test signals for response. The multiple test signals sent by the inverter to the access device can be set by the operation and maintenance personnel of the device management system according to the type of device that can be connected to the inverter. For example, Figure 4 The types of devices that can be connected to the inverter are shown to include cloud communication boxes, battery packs / BMS, alarms, smart meters, digital chips, smart junction boxes, LED display lights, and DC arc detection AFCI / component-level shutdown RSD switches, which are not specifically limited in the embodiments of the present application.

[0062] After receiving the test message corresponding to the device type of the access device, the access device returns a response message to the inverter.

[0063] Correspondingly, the inverter receives the response message sent by the access device, and determines the device type of the access device according to the test signal corresponding to the response message.

[0064] Exemplarily, taking the access devices that can be connected to the inverter as cloud communication boxes, battery packs, smart junction boxes, LED display lights, LCD displays, smart meters, etc. as an example, the test signals corresponding to each device are shown in Table 1 below.

[0065] Table 1: Mapping relationship between device type and test signal

[0066] Device Type Test signal Cloud communication box Signal 1 Battery Pack Signal 2 Smart Junction Box Signal 3 LED display light Signal 4 LCD Display Signal 5 Smart Meter Signal 6

[0067] Based on the mapping relationship table shown in Table 1 above, the inverter sends signals 1-6 to the access device through the port at intervals of preset duration. If a response message returned by the access device is received within the preset duration after the inverter sends signal 1, the sending of signals 2-6 is stopped, and the device type of the access device is determined to be a cloud communication box; if a response message returned by the access device is received within the preset duration after the inverter sends signal 2, the sending of signals 3-6 is stopped, and the type of the access device is determined to be a battery pack; and so on, if a response message returned by the access device is received within the preset duration after the inverter sends signal 6, the access device is determined to be a smart meter.

[0068] In some embodiments, if no response message is received within a preset time after the inverter sends multiple test signals, the inverter determines that the current access device cannot be identified, generates and issues an exception report, wherein the exception report includes the port to which the access device is connected.

[0069] It should be noted that the inverter can display the abnormal report through the connected display to send the abnormal report to the user, or send the abnormal report to the user's terminal through the connected communication module. The embodiments of the present application do not specifically limit this.

[0070] In some embodiments, when a device is detected to be connected to a port, the inverter identifies the device type of the connected device through the port. Exemplarily, the inverter may also send a type request message to the connected device and receive the device type returned by the connected device in response to the type request message.

[0071] It should be noted that if the device type returned by the access device in response to the type request message received by the inverter is an unrecognizable garbled code, the access device is identified, and an abnormality report is generated and issued.

[0072] S302: When the device type of the access device is successfully identified, the inverter establishes a communication connection with the access device.

[0073] As a possible implementation, the inverter determines whether the identification is successful based on the device type identification of the access device in step S301. Further, if the device type of the access device is successfully identified, the inverter establishes a communication connection with the access device so that the access device and the inverter form an integrated system.

[0074] In some embodiments, after the inverter establishes a communication connection with the access device, the operating data and / or control instructions issued by the access device can be forwarded by the inverter to other devices; the operating data and / or control instructions sent by other devices to the access device can also be forwarded by the inverter to the access device, and each device is integrated through the inverter.

[0075] It should be noted that after the inverter establishes a communication connection with the access device, the inverter can send the device operation information related to the access device and the system function to different systems or read it from different systems through the port. For example, data that requires energy control is sent to the EMS energy management system, and data such as battery SOC that requires data is read from the BMS battery management system.

[0076] In some embodiments, the inverter is respectively connected to a first device and a second device, the inverter receives a target message sent by the first device, and forwards the target message to the second device, where the target message includes operating data and / or control instructions.

[0077] During the data interaction between the inverter and the access device, the real-time operation data can be packaged and sent together with the control instructions to avoid delays in the data fields of the same device. For example, the charging pile needs to obtain the current voltage and the power limit instruction given by the inverter. The integrated package transmission ensures that the data of these two data types are obtained at the same time, and there will be no problem of only receiving the power limit instruction but not obtaining the voltage. If there is a delay in the acquisition of voltage, the output power requires voltage to determine the current, which may cause serious safety problems or even system failures.

[0078] In some embodiments, messages between the inverter and the access device are encrypted based on a global digital encryption algorithm to ensure data security between the inverter and other access devices.

[0079] S303: The inverter starts a function corresponding to the device type of the connected device.

[0080] As a possible implementation method, after establishing a communication connection with the access device, the inverter controls the function code domain corresponding to the device type to open according to the device type of the access device, so as to realize the function of automatically starting the access device after the access device is connected to the inverter.

[0081] It can be understood that in the device management method provided in the present application, when the inverter detects that there is a device connected to the port, it can automatically identify the access device and establish a communication connection with the access device if the match is successful, so that the inverter and the access device form an integrated system, which can transmit information to the access device through the inverter and automatically start the function corresponding to the device type of the access device, thereby realizing plug-and-play of the access device.

[0082] In one design, when a device connected to the inverter is removed, in order to ensure the normal operation of the system, the device management method provided by the present application is as follows: Figure 5 As shown, it also includes S501-S503.

[0083] S501: When the inverter detects that a device is removed from a port, it determines to remove the device.

[0084] As a possible implementation, the inverter detects multiple ports in real time and determines whether a device has been removed through port power supply and / or port contacts. Further, when it is detected that a device has been removed from a port, the inverter determines to remove the device based on the historical access status of the port.

[0085] In some embodiments, after an access device is connected to the inverter through a port, the inverter establishes and stores a mapping relationship between the port and the access device. After detecting that a device is removed from the port, the inverter determines to remove the device based on the stored mapping relationship.

[0086] Exemplarily, the mapping relationship table between ports and access devices is shown in Table 2 below.

[0087] Table 2: Mapping relationship between device type and test signal

[0088] port Access device Port 1 LED display light Port 2 / Port 3 / Port 4 LCD Display Port 5 Smart Junction Box Port 6 /

[0089] For example, if the inverter detects that a device at port 5 is removed, based on the mapping relationship shown in Table 2 above, it is determined that the removed device is a smart junction box.

[0090] S502: The inverter disconnects the communication connection with the removed device.

[0091] S503: The inverter shuts down and removes functions corresponding to the device.

[0092] As a possible implementation method, the inverter closes the function code domain corresponding to the removed device and stops calling the functions of the removed device to avoid abnormalities caused by other devices still calling corresponding functions after the removed device is removed.

[0093] It should be noted that the embodiment of the present application does not specifically limit the execution order of the above-mentioned step S502 and step S503. Step S502 can be executed first, or step S503 can be executed first, or steps S502 and S503 can be performed simultaneously.

[0094] In one design, Figure 6 A flow chart of a device management method is shown. First, the inverter performs port detection to determine whether a device is removed or connected.

[0095] Furthermore, if the inverter determines that a device is removed, the inverter disconnects the communication connection with the removed device and turns off the function of removing the device.

[0096] If the inverter determines that a device is connected, the inverter identifies the device type of the connected device through the port. If the identification is successful, a communication connection is established with the connected device and the function of the connected device is enabled; if the identification fails, an abnormality report is generated and sent.

[0097] In some examples, the inverter includes 1, 2, 3 to N ports, wherein the number of ports, the appearance, the pins, the number of connecting lines, the communication method, and the communication protocol are not limited.

[0098] For example, when the LED display light originally connected to port 1 of the inverter is removed, the inverter recognizes the removed device, disconnects the communication connection with the LED display light, and turns off the function of the LED display light; when the LCD display screen is connected to port N of the inverter, the inverter automatically recognizes that the port N is connected to a new device, and starts to identify whether the connected device matches. When it is correctly identified as an LCD display screen, the display function of the LCD display screen is automatically turned on, achieving the effect of seamless removal of options and seamless plug-and-play.

[0099] For another example, the cloud data stick originally connected to port 1 of the inverter is removed and replaced with a smart junction box on the same interface. The system automatically recognizes that the cloud data stick is disconnected, turns off the communication function of the data stick, identifies the smart junction box, reads the parameter data of the smart junction box, and sends control instructions to the smart junction box according to user settings.

[0100] In one design, the present application proposes a device management apparatus for executing the above device management method, the device management apparatus is integrated with the inverter, such as Figure 7 As shown, the equipment management device includes a port identification module, a digital integration module and a functional module.

[0101] Among them, the port identification module is used to detect the status of the port and determine whether there is a device connected or removed. The port identification module is also used to identify the device type of the access device; the digital integration module is used to establish a communication connection between the access device and the inverter, and in the process of data interaction with the access device, the real-time operation data and control instructions are packaged and sent in an integrated manner; the function module is used to control the opening or closing of the function code domain corresponding to the device, so as to realize the opening of the corresponding function when the device is connected, and the closing of the corresponding function when the device is removed.

[0102] The above mainly introduces the solution provided by the embodiment of the present application from the perspective of the method. In order to realize the above functions, it includes hardware structures and / or software modules corresponding to the execution of each function. Those skilled in the art should easily realize that, in combination with the units and algorithm steps of each example described in the embodiment disclosed herein, the embodiment of the present application can be implemented in the form of hardware or a combination of hardware and computer software. Whether a function is executed in the form of hardware or computer software driving hardware depends on the specific application and design constraints of the technical solution. Professional and technical personnel can use different methods to implement the described functions for each specific application, but such implementation should not be considered to exceed the scope of the present application.

For example, each functional module can be divided according to each function, or two or more functions can be integrated into one processing module. The above integrated module can be implemented in the form of hardware or in the form of software functional modules. Optionally, the division of modules in the embodiment of the present application is schematic and is only a logical function division. There may be other division methods in actual implementation.
