[0039] See also Figure 1 As shown, it is a flow chart of a practical training method for a power supply device provided in some embodiments of the present application. The practical training method provided in some embodiments of the present application is applied to Figure 2 The training console 1 shown below. Figure 1 and Figure 2The practical training method of the power supply device provided in some embodiments of the present application is described in detail, wherein the power supply device here can be but is not limited to a locomotive power supply device, such as a DC600V power supply device applied to a train. Specifically, the practical training method provided in some embodiments of the present application includes S02, S04 and S06, and the description of each step is as follows.

[0040] S02: Based on the category of the operation selected by the user, a training control interface of the corresponding category is displayed. The training control interface has an operating status display area for displaying the current operating status of the power supply model, an input area for inputting the operating parameter setting values ​​of the power supply model, and a training guidance information display area for displaying the current operating status of the power supply model.

[0041] The training console 1 includes a controller 11 and a display 12. The controller 11 obtains the user's selected operation based on the display interface of the display 12. When the user needs to perform training operations on the power supply device, he can select the training system corresponding to the category of the power supply model based on the display interface of the display 12 to enter, so as to display the corresponding training control interface for the user to operate and display the operating status information of the power supply model and the corresponding training operation guidance information. Specifically, the schematic diagram of the training control interface 123 corresponding to the power supply model currently requiring training is shown in FIG. Figure 3 As shown, the training control interface 123 displayed by the display 12 includes an operation status display area 1231, an input area 1232, and a training guidance information display area 1233. The operation status display area 1231 is used to display the operation status information of the power model, the input area is used to set the operation parameters of the power model, and the training guidance information display area 1233 is used to display the training guidance information corresponding to the current operation status of the power model.

[0042] The power supply model refers to a simulation model of a power supply device that needs to be trained. Specifically, it can be a physical simulation model. Taking the DC600V power supply device of a locomotive as an example, it includes an inverter cabinet, a charging cabinet, and further includes a battery cabinet for charging based on the charging cabinet. Then the power supply model in the present application includes an inverter cabinet model and a charging cabinet model. Among them, the inverter cabinet model is a simulation model of the inverter cabinet, and the charging cabinet model is a simulation model of the charging cabinet. In some embodiments, the inverter cabinet model and the charging cabinet model can both be physical simulation models, so that users can perform training operations based on the real object, which can effectively improve the user's practical ability to repair the power supply device. Different categories of power supply models can include, but are limited to, inverter cabinet models and charging cabinet models. The power supply model will be further described in detail later when describing the training system for the power supply device provided in the embodiment of the present application.

[0043] When the user needs to perform training operations on a certain category of power supply models, he first selects the corresponding training control content based on the display interface of the display 12 to display the training control interface 123 corresponding to the category of the power supply model that currently needs to be trained, so that the operating parameters of the power supply model that currently needs to be trained can be set based on the input area 1232, and the current operating status information of the power supply model can be intuitively obtained from the operating status display area 1231 to understand the current operating status of the power supply model, and according to the training guidance information displayed in the training guidance information display area 1233, the power supply model is subjected to corresponding actions, so as to achieve a more comprehensive and systematic understanding of the working principle, operating environment and maintenance knowledge of the power supply device based on the actual operation of the power supply model.

[0044] S04: According to the user's operation on the input area, the operating parameter setting values ​​are sent to the power supply model, and when the currently displayed training control interface is the power supply fault situation training control interface, according to the set fault simulation strategy, the corresponding category of fault signal is sent to the power supply model to control the corresponding PLC contact action in the main circuit of the power supply model, so that the power supply model enters a fault operation state corresponding to the category of the fault signal.

[0045] The operating parameters of the power model include but are not limited to the input parameters and output parameters of the power model. The input parameters may be input voltage and / or input current, and the output parameters may be output voltage and / or output current. When the power model is an inverter cabinet model, the operating parameters of the power model may also include the alarm temperature of the heat sink in the inverter. When the heat sink temperature of the inverter reaches the alarm temperature, a high temperature alarm prompt will be issued.

[0046] The controller 11 obtains the operating parameter setting value of the power model based on the user's input operation on the input area 1232, and sends the operating parameter setting value of the power model to the control module in the power model, so that the control module controls the operation of the power model according to the setting value of the operating parameter. When the category of the training control interface 123 is the normal training control interface under the normal operation of the power model, the controller 11 only sends the setting value of the operating parameter to the control module of the power model, and the power model is in a normal operating state. The user can understand the operating state of the power model under normal conditions based on the input information and display information in the training control interface 123, and perform training operations on the power model under normal operation according to the training guidance information.

[0047] When the category of the training control interface 123 is the fault situation training control interface under the fault operation condition of the power supply model, in addition to sending the set values ​​of the operating parameters to the control module of the power supply model, the controller 11 also sends the corresponding category of fault signals to the control module in the power supply model based on the fault simulation program. The control module triggers the corresponding PLC contact action in the power supply model based on the fault signal to put the power supply model into a fault operation state, so that the user can perform maintenance training on the power supply device under fault conditions.

[0048] PLC contacts refer to switches set in the main circuit of the power supply model. PLC contacts at different positions trigger actions based on different types of fault signals. When the controller 11 does not send a fault signal to the power supply model, these PLC contacts are not triggered and are in the state of normal operation of the power supply model.

[0049] S06: Acquire the operation status information of the power supply model, and determine the display content of the operation status display area according to the operation status information.

[0050] The operation status information of the power supply model includes, but is not limited to, the detection point status information of the power supply model, the control point status information of the power supply model and the operation parameter detection information of the power supply model.

[0051] The detection point refers to the detection point in the power supply model that needs to be monitored. For example, if the power supply device takes the DC600V power supply device of the locomotive as an example, if the power supply model that needs to be trained is the inverter cabinet model corresponding to the inverter cabinet in the DC600V power supply device, then its corresponding detection points include the DC600V fault detection point for whether the DC600V power supply is faulty, the DC110V fault detection point for whether the DC110V power supply is faulty, the inverter operation detection point for whether the inverter in the inverter cabinet model is running, and / or the inverter fault detection point for whether the inverter is faulty. When the power supply model is the charging cabinet model of the charging cabinet in the DC600V power supply device, its corresponding detection points include the DC600V fault detection point for whether the DC600V power supply is faulty and the DC110V fault detection point for whether the DC110V power supply is faulty.

[0052] The control point status information refers to the opening and closing status information of the PLC contacts in the power model. One PLC contact corresponds to one control point. The opening and closing status information of the PLC contacts in the power model is displayed accordingly in the operation status display area 1231 in the training control interface 123. If the opening and closing status of the PLC contacts in the power model changes, the operation status of the corresponding control point in the operation status display area 1231 will also change accordingly. The PLC contacts of the power model can be opened and closed based on the control module in the power model, or based on manual operation by the user. After the user manually controls the opening and closing status of the PLC contacts to change, the control module in the power model can detect it and send the change result of the opening and closing status of the PLC contacts to the controller 11, and the controller 11 updates the opening and closing status of the corresponding control point in the operation status display area 1231.

[0053] According to the training method provided in the embodiment of the present application, the user can perform corresponding operations on the simulation model of the power supply device, that is, the power supply model, based on the operation of the training control interface, and display the operating status of the power supply model and the corresponding training guidance information, and send a fault signal to the power supply model based on the user operation to simulate the faulty operating environment of the power supply device, so that the user can perform training operations on the power supply model under different operating states such as normal and faulty according to different operating status information and corresponding training guidance information, which helps the user to perform training operations on the installation, debugging, maintenance and troubleshooting of the power supply device, and effectively improves the user's practical operation skills. In addition, the training method provided in the embodiment of the present application performs human-computer interaction with the user based on the training control interface, which is convenient for the user to observe and analyze, and effectively improves the user's learning, research and development efficiency of the power supply device.

[0054] See also Figure 4 As shown, it is a flow chart of displaying a corresponding category of training control interface in the training method provided in an embodiment of the present application. In some embodiments, the step of displaying a corresponding category of training control interface according to the user's selected operation category in the above S02 further includes S022, S024 and S026, and each step is described as follows.

[0055] S022: Based on the practical training system login interface, obtain the user's identity information, and display the practical training content selection interface according to the user's identity information.

[0056] The power supply device takes a DC600V power supply device as an example, and the corresponding schematic diagram of the training system login interface 121 is as follows: Figure 5As shown, the training system login interface 121 has a user identity information login area, wherein the user identity information includes the user's account information and password information. Based on the identity information entered by the user in the training system login interface 121, it is determined whether the user has the authority to log in to the training system. If so, the training system is entered to display the following information: Figure 6 The training content selection interface 122 is shown.

[0057] S024: According to the user's selection operation on the training content selection interface, enter the training operation main interface corresponding to the category of the power model currently requiring training, and the training operation main interface is provided with a training control category selection key for training and controlling the power model.

[0058] The training content selection interface 122 displays training systems corresponding to different categories of power supply models, such as an inverter cabinet training system and a charging cabinet training system. Different types of training systems are used to train corresponding categories of power supply models. For example, if the current user needs to perform training operations on the inverter cabinet in the power supply device, the user can click on the inverter cabinet training system in the training content selection interface 122, and the controller 11 controls the display 12 to display the inverter cabinet training control interface corresponding to the inverter cabinet model based on the user's selected operation; if the current user needs to perform training operations on the charging cabinet in the power supply device, the user can click on the charging cabinet training system in the training content selection interface 122, and the controller 11 controls the display 12 to display the charging cabinet training control interface corresponding to the charging cabinet model based on the user's selected operation.

[0059] S026: Based on the selection operation of the practical training control category selection key, a practical training control interface of the corresponding category is displayed.

[0060] Different types of training control main interfaces are respectively provided with training control category selection keys. Based on the user's selection operation on the training control category selection key, the controller 11 displays the training control interface corresponding to the training content, so that the user can perform training operations of the corresponding content.

[0061] The categories of training control interfaces include, but are not limited to, normal situation training control interface, fault situation training control interface and hardware setting control interface. Among them, the normal situation training control interface refers to the first training control interface when the power supply model of the corresponding category is in normal operating state, and the fault situation training control interface refers to the first training control interface when the power supply model of the corresponding category is in faulty operating state. The normal situation training control interface is used to perform training control on the power supply device in normal operating state, and the fault situation training control interface is used to perform training control on the power supply device in faulty operating state. The hardware setting control interface refers to an interface for users to set the hardware parameters of the power supply model that currently needs to be trained.

[0062] If the power supply device currently to be trained is the inverter cabinet in the DC600V power supply device, the power supply model is the inverter cabinet model, and the main interface of the training control is as follows: Figure 7 The main interface of different types of practical training and control can be an interface that displays the practical training and control category selection keys separately, or it can be a normal practical training and control interface of the corresponding type. Figure 7 The training control category selection keys in the normal situation training control interface shown are the selection keys marked with "normal situation", "fault situation" and "hardware setting" in the first row. When the user selects one of the training control category selection keys, the controller 11 controls the display 12 to display the corresponding training control interface based on the user's selection action.

[0063] The status display area of ​​the inverter cabinet normal training control interface is used to display the operating status information of the inverter cabinet model. Figure 7 As shown, the status display area of ​​the normal training control interface of the inverter cabinet includes a detection point display area, a control point display area and a detection display area.

[0064] The detection point display area of ​​the inverter cabinet training control display interface is used to display the status of each detection point of the inverter cabinet model, such as the DC600V fault detection point, DC110V detection point, inverter operation detection point and inverter fault detection point. If the indicator light of the DC600V fault detection point is on, it means that the DC600V power supply of the inverter cabinet model has a fault. If the indicator light of the DC600V fault detection point is off, it means that the DC600V power supply of the inverter cabinet model is normal. If the indicator light of the DC110V fault detection point is on, it means that the DC110V power supply of the inverter cabinet model has a fault. If the indicator light of the DC110V fault detection point is off, it means that the DC110V power supply of the inverter cabinet model is normal. If the indicator light of the inverter operation detection point is on, it means that the inverter of the inverter cabinet model is in operation. If the indicator light of the inverter operation detection point is off, it means that the inverter of the inverter cabinet model is not in operation. If the indicator light of the inverter fault detection point is on, it means that the inverter of the inverter cabinet model has a fault. If the indicator light of the inverter fault detection point is off, it means that the inverter of the inverter cabinet model is normal.

[0065] The control point display area of ​​the inverter cabinet training control display interface is used to display the opening and closing status of different PLC contacts in the inverter cabinet model. The PLC contacts include the main contactor, pre-charging contactor, discharge contactor and output contactor at the input end of the first inverter cabinet NBQA and the second inverter cabinet NBQB, including a total of 8 PLC contacts, i.e. 8 control points.

[0067] The input area of ​​the inverter cabinet normal training control model is used to input the DC600V set value, DC110V set value, and the radiator temperature alarm set value in the inverter cabinet model (corresponding to Figure 7 The temperature setting in the inverter model), the output voltage adjustment setting value and the output circuit adjustment setting value.

[0068] The training guidance information display area of ​​the normal training control interface of the inverter cabinet includes the training operation guidance display area of ​​the inverter cabinet model under normal operation and the schematic diagram display area of ​​the inverter cabinet model. Figure 7 As shown, the content displayed in the training operation guidance display area of ​​the normal training control interface of the inverter cabinet includes the training operation steps (process steps) and the training operation guidance content corresponding to each training operation step (for details of the process steps). The schematic display area is used to display the schematic diagram of the inverter cabinet model.

[0069] Furthermore, the normal training control interface of the inverter cabinet is also provided with a training operation step selection area, and the controller 11 selects the corresponding training operation step based on the user's selection operation of the training operation step selection area. Specifically, the training operation step selection area is provided with a previous unselected key and a next selected key.

[0070] Furthermore, the normal training operation interface of the inverter cabinet is also provided with a schematic diagram type selection area, and the controller 11 displays the corresponding type of schematic diagram in the schematic diagram display area based on the user's selection operation on the schematic diagram type selection area. For the inverter cabinet model, the corresponding schematic diagram types include the inverter cabinet principle main diagram (including the principle schematic diagram of the first inverter cabinet NBQA and the second inverter cabinet NBQB), the inverter cabinet NBQA schematic diagram and the inverter cabinet NBQB schematic diagram. The schematic diagram type selection area is provided with an inverter cabinet principle main diagram selection key, an inverter cabinet NBQA schematic diagram selection key and an inverter cabinet NBQB schematic diagram selection key. The controller 11 controls the display of the corresponding schematic diagram in the schematic diagram display area based on the currently selected schematic diagram selection key. In addition, the controller 11 also updates the status of the corresponding PLC contacts or switches in the schematic diagram displayed in the schematic diagram display area according to the status changes of each PLC contact or switch in the inverter cabinet model.

[0071] See also Figure 8As shown, it is a schematic diagram of the inverter cabinet fault situation training control interface. In addition to the difference between the content displayed in the training guidance information display area of ​​the inverter cabinet fault situation training control interface and the inverter cabinet normal situation training control interface, it can further include a fault component display area. The training guidance information display area in the inverter cabinet fault situation training control interface is used to display the fault list information of the inverter cabinet model and the fault solution information corresponding to each type of fault in the fault list information. Among them, the fault list information displays fault category information, that is, fault code, and fault details information corresponding to each fault category. The fault component display area is used to display the image of the component that is currently faulty in the inverter cabinet model, so as to guide the user to find the corresponding fault component in the inverter cabinet model.

[0072] See also Fig. 9 As shown, it is a schematic diagram of the inverter cabinet hardware setting control interface. Based on the user's selection operation of the "Hardware Setting" selection key in the inverter cabinet training control interface, the controller 11 controls the display 12 to display the inverter cabinet hardware setting control interface. The user can set the hardware parameters of the inverter cabinet model accordingly based on the inverter cabinet hardware setting control interface, and send them to the inverter cabinet model after being identified and processed by the controller 11.

[0073] If the power supply device currently to be trained is a charging cabinet in a DC600V power supply device, the power supply model is the charging cabinet model, and the main interface of the training control is as follows: Fig.10 The interface shown is the normal training control interface of the charging cabinet. The training control category selection keys in the normal training control interface of the charger are the selection keys marked with "normal situation", "fault situation" and "hardware setting" in the first row. When the user selects one of the training control category selection keys, the controller 11 controls the display 12 to display the corresponding training control interface based on the user's selection action.

[0074] The status display area of ​​the normal operation training interface of the charging cabinet is used to display the operating status information of the charging cabinet model. Fig.10 As shown, the status display area of ​​the normal training control interface of the charging cabinet also includes a detection point display area, a control point display area and a detection display area.

[0075] The detection point display area of ​​the charging cabinet training control interface is used to display the status of each detection point of the charging cabinet model, such as the DC600V fault detection point and the DC110V detection point. If the indicator light of the DC600V fault detection point is on, it means that the DC600V power supply of the charging cabinet model has a fault. If the indicator light of the DC600V fault detection point is off, it means that the DC600V power supply of the charging cabinet model is normal. If the indicator light of the DC110V fault detection point is on, it means that the DC110V power supply of the charging cabinet model has a fault. If the indicator light of the DC110V fault detection point is off, it means that the DC110V power supply of the charging cabinet model is normal.

[0076] The control point display area of ​​the charging cabinet training control interface is used to display the opening and closing status of different PLC contacts in the charging cabinet model. Each PLC contact includes the main contactor and pre-charging contactor of the charger and unidirectional inverter in the charging cabinet model.
