[0035] Currently, with the rapid development of the photovoltaic field, the types of devices that can be connected to the photovoltaic system are also increasing. The devices can be connected to the photovoltaic system through the inverter to realize data interaction and energy transmission. In the related technology, after the device is connected to the photovoltaic system, the operation and maintenance personnel need to set it up before the corresponding function can be realized, which is time-consuming and laborious.

[0036] To solve the above problems, the present application provides a device management method, device, and storage medium. The device management method is applied to an inverter, and the method comprises: the inverter detects that a port has a device connected, identifies the device type of the connected device, and establishes a communication connection with the connected device if the identification of the device type of the connected device is successful. Further, the inverter starts the function corresponding to the device type of the connected device.

[0037] 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 connected device if the matching is successful. The inverter and the connected device form an integrated system, which can transmit information to the connected device through the inverter and automatically start the function corresponding to the device type of the connected device, realizing plug-and-play of the connected device.

[0038] FIG. 1 shows a device management system. The device management method provided by the present application can be applied to the device management system shown in FIG. 1 to realize plug-and-play of the device connected to the inverter and facilitate user operation. As shown in FIG. 1, the device management system 10 comprises an inverter 11 and a connected device 12.

[0039] Among them, the inverter 11 and the connected device 12 are connected through a connection line, the inverter 11 comprises a plurality of ports for connecting other devices, and the connected device 12 exemplarily comprises a cloud communication box, a battery pack, a smart junction box, a light-emitting diode (LED) display lamp, a liquid crystal display (LCD), a smart meter, etc.

[0040] It should be noted that the present application does not make specific limitations on the connection form of the hardware connection between the inverter 11 and the connected device 12, such as the port type, port quantity, port communication quantity, and port form of the inverter, etc.

[0041] In the device management system 10 shown in FIG. 1, the inverter 11 can determine whether a device is connected or removed by detecting the ports included therein.

[0042] The inverter 11 can also identify the connected device 12 through the port to determine the device type of the connected device.

[0043] Further, the inverter 11 can also establish a communication connection with the access device 12 through the port to form an integrated system with the access device 12.

[0044] The inverter 11 can also start a function corresponding to the device type of the access device 12 to realize plug and play of the access device 12.

[0045] In some embodiments, as shown in FIG. 2, the device management method provided by the present application can be applied to an embedded operating system taking the inverter as a hardware computing platform, and can work with a communication system (CMS), an energy management system (EMS), etc. in a device system.

[0046] FIG. 3 is a flow diagram of a device management method according to some example embodiments. In some embodiments, the above-mentioned device management method can be applied to the inverter 11 in the device management system 10 as shown in FIG. 1. Hereinafter, the device management method is described by taking the application of the device management method to the inverter 11 as an example.

[0047] As shown in FIG. 3, the device management method provided by the present application includes the following S301-S303.

[0048] S301, the inverter identifies the device type of the access device when detecting that the port has a device access.

[0049] As a possible implementation, the inverter detects multiple ports in real time to determine whether there is a device access through the port power supply and / or the port contact. Further, when detecting that the port has a device access, the inverter identifies the device type of the access device through the port.

[0050] In some embodiments, the inverter determines whether there is a device access through the port power supply, which can be exemplified by the inverter determining whether there is a device access by detecting whether there is a voltage output change or a voltage input change in each port.

[0051] The inverter determines whether there is a device access through the port contact, which can be exemplified by the inverter determining whether there is a device access according to the voltage and current changes of the port contact.

[0052] When detecting that the port has a device access, the inverter identifies the device type of the access device through the port, which can be exemplified by the inverter sending multiple test signals to the access device.

[0053] The multiple test signals include test signals corresponding to different device types.

[0054] It should be noted that the devices of different device types are configured with test signals for response, and the multiple test signals sent by the inverter to the access device can be set in the inverter by an operation and maintenance personnel of the device management system according to the device types that can access the inverter. For example, as shown in FIG. 4, the device types that can access the inverter include a cloud communication box, a battery pack / BMS, an alarm, a smart meter, a digital chip, a smart junction box, an LED display lamp, and a direct-current arc detection AFCI / component-level shutdown RSD switch, which are not limited in the embodiments of the present application.

[0055] After receiving the test message corresponding to the device type of the access device, the access device returns a response message to the inverter.

[0056] 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.

[0057] For example, the access devices that can access the inverter are the cloud communication box, the battery pack, the smart junction box, the LED display lamp, the LCD display, the smart meter, and the like, and the test signals corresponding to each device are shown in Table 1.

[0058] Table 1: Mapping relationship table of device type and test signal

[0059]

[0060] Based on the mapping relationship table shown in Table 1, the inverter sends signals 1-6 to the access device through the port at an interval of a preset time length. If the response message returned by the access device is received within the preset time length after the inverter sends signal 1, the inverter stops sending signals 2-6, and determines that the device type of the access device is the cloud communication box. If the response message returned by the access device is received within the preset time length after the inverter sends signal 2, the inverter stops sending signals 3-6, and determines that the device type of the access device is the battery pack. Similarly, if the response message returned by the access device is received within the preset time length after the inverter sends signal 6, the inverter determines that the access device is the smart meter.

[0061] In some embodiments, if no response message is received within the preset time length after the inverter sends the 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 accessed by the access device.

[0062] It should be noted that the inverter can display the abnormality report through the connected display to realize sending the abnormality report to the user, or send the abnormality report to the terminal of the user through the connected communication module, and the embodiments of the present application do not make specific limitation.

[0063] In some embodiments, in the case that the port is detected to have the device access, the inverter identifies the device type of the access device through the port, and the inverter can further send a type request message to the access device and receive the device type returned by the access device in response to the type request message.

[0064] 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 random code, it is determined that the access device is identified, and an abnormality report is generated and sent.

[0065] S302, in the case that the device type identification of the access device is successful, the inverter establishes a communication connection between the inverter and the access device.

[0066] As a possible implementation manner, the inverter determines whether the identification is successful based on the device type identification of the access device in the above step S301. Further, the inverter establishes a communication connection between the inverter and the access device in the case that the device type identification of the access device is successful, so that the access device and the inverter form an integrated system.

[0067] In some embodiments, after the inverter establishes the communication connection with the access device, the operation data and / or control instruction sent by the access device can be forwarded by the inverter to other devices, and the operation data and / or control instruction 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.

[0068] It should be noted that after the inverter establishes the 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 from different systems through the port. For example, the data required for energy control is sent to the EMS energy management system, and the data required for the battery SOC is read from the BMS battery management system.

[0069] In some embodiments, the inverter is connected with a first device and a second device respectively, the inverter receives a target message sent by the first device, and forwards the target message to the second device, and the target message includes operation data and / or control instruction.

[0070] In the data interaction process between the inverter and the access device, the real-time running data can be packaged and sent together with the control instruction, so as to avoid the delay of the data field of the same device. For example, the charging pile needs to obtain the current voltage and needs to obtain the power limit instruction given by the inverter. The integrated packaging ensures that the data of the two data types are obtained at the same time, and the problem that only the power limit instruction is received but the voltage cannot be obtained does not occur. If the acquisition of the voltage is delayed, the output power needs the voltage to determine the current, which may cause serious safety problems or even system failure.

[0071] In some embodiments, the messages between the inverter and the access device are encrypted based on a global digital encryption algorithm, so as to ensure the data security between the inverter and other access devices.

[0072] S303, the inverter starts the function corresponding to the device type of the access device.

[0073] As a possible implementation manner, after the inverter establishes the communication connection with the access device, the inverter controls the function code field corresponding to the device type of the access device to be opened, so as to automatically start the function of the access device after the access device accesses the inverter.

[0074] It can be understood that in the device management method provided in the present application, when the inverter detects that there is a device accessing the port, the access device can be automatically identified, and in the case of successful matching, the communication connection between the inverter and the access device is established, so that the inverter and the access device form an integrated system, the information can be transmitted to the access device through the inverter, and the function corresponding to the device type of the access device is automatically started, so as to realize the plug and play of the access device.

[0075] In one design, when the device accessing the inverter is removed, in order to ensure the normal operation of the system, the device management method provided in the present application, as shown in FIG. 5, further includes S501-S503.

[0076] S501, the inverter determines the removed device when detecting that there is a device removed from the port.

[0077] As a possible implementation manner, the inverter detects the multiple ports in real time, and determines whether there is a device removed through the port power supply and / or the port contact. Further, when detecting that there is a device removed from the port, the inverter determines the removed device according to the historical access situation of the port.

[0078] In some embodiments, after the access device accesses the inverter through the port, the inverter establishes the mapping relationship between the port and the access device and stores it, and after detecting that there is a device removed from the port, the inverter determines the removed device according to the stored mapping relationship.

[0079] For example, the mapping relationship table between the ports and the access devices is shown in Table 2.

[0080] Table 2: Mapping relationship table between the device types and the test signals

[0081]

[0082] For example, if the inverter detects that the device of port 5 is removed, it is determined that the removed device is the smart patch panel based on the mapping relationship shown in Table 2.

[0083] S502, the inverter disconnects the communication connection between the inverter and the removed device.

[0084] S503, the inverter closes the function corresponding to the removed device.

[0085] As a possible implementation, the inverter closes the function code field corresponding to the removed device, and stops the function call to the removed device, so as to avoid the abnormality caused by the function call of other devices to the corresponding function after the removed device is removed.

[0086] It should be noted that the execution order of the above steps S502 and S503 is not limited, and the step S502 can be executed first, or the step S503 can be executed first, or the steps S502 and S503 can be executed simultaneously.

[0087] In one design, FIG. 6 shows a flowchart of a device management method. First, the inverter performs port detection to determine whether a device is removed or a device is accessed.

[0088] Further, if the inverter determines that a device is removed, the inverter disconnects the communication connection between the inverter and the removed device, and closes the function of the removed device.

[0089] If the inverter determines that a device is accessed, the inverter identifies the device type of the accessed device through the port. In the case of successful identification, the communication connection between the inverter and the accessed device is established, and the function of the accessed device is opened. In the case of failed identification, an exception report is generated and sent.

[0090] In some examples, the inverter includes 1, 2, 3 to N ports, wherein the number of ports is not limited, the appearance is not limited, the Pin pin is not limited, the number of connection lines is not limited, the communication mode is not limited, and the communication protocol is not limited.

[0091] For example, the LED display lamp originally connected to port 1 of the inverter is removed, the inverter recognizes the removal of the device, disconnects the communication connection between the LED display lamp, and closes the function of the LED display lamp; when the LCD display screen is connected to port N of the inverter, the inverter automatically recognizes that port N is connected to a new device, and starts to identify whether the connected device matches, and when correctly identifying that it is an LCD display screen, automatically opens the display function of the LCD display screen, realizing the effect of inductive removal and inductive plug-and-play of the optional component.

[0092] For another example, the cloud data stick originally connected to port 1 of the inverter is removed, and the intelligent junction box is replaced to the same interface, the system automatically recognizes the disconnection of the cloud data stick, closes the communication function of the data stick, recognizes the intelligent junction box, reads the parameter data of the intelligent junction box, and sends a control instruction to the intelligent junction box according to the user setting.

[0093] In one design, the present application provides a device management apparatus for executing the above-mentioned device management method, and the device management apparatus is integrated on the inverter, as shown in FIG. 7, the device management apparatus includes a port recognition module, a digital integration module, and a function module.

[0094] The port recognition module is used to detect the state of the port, determine whether there is a device access or device removal, and the port recognition module is also used to identify the device type of the connected device; the digital integration module is used to establish the communication connection between the connected device and the inverter, and integrally package and send the real-time running data and the control instruction in the data interaction process between the connected device; the function module is used to control the opening or closing of the function code field 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.

[0095] The above mainly introduces the scheme provided by the embodiments of the present application from the perspective of the method. In order to realize the above functions, it contains the hardware structure and / or software module corresponding to the execution of each function. Those skilled in the art should easily realize that the units and algorithm steps of each example described in combination with the embodiments disclosed in the present text can be realized in the form of hardware or the combination of hardware and computer software. Whether a certain function is executed by hardware or computer software driven hardware depends on the specific application and design constraints of the technical scheme. Professional technicians can use different methods to realize the described functions for each specific application, but such implementation should not be considered beyond the scope of the present application.

[0096] The embodiments of the present application can divide the function modules of the user equipment according to the above method examples. For example, each function module can be divided according to each function, or two or more functions can be integrated in one processing module. The integrated module can be realized in the form of hardware or in the form of a software function module. Optionally, the division of the modules in the embodiments of the present application is illustrative, and is only a logical function division. In actual implementation, another division manner can be used.
