[0030] It should be noted that the term "comprising" will be used in the embodiments of this application to indicate the presence of the features declared thereafter, but does not exclude the addition of other features.
[0031] During the electrical engineering training on the train, it is necessary to conduct various disassembly and assembly exercises on the actual integrated control cabinet, charger, inverter, and various equipment in the carriage. Therefore, it is necessary to provide integrated control cabinets, inverters, and chargers with the same logic as those in the train carriage for training purposes. However, integrated control cabinets, inverters, and chargers need to be integrated with other mechanisms of the train to operate normally. Individual integrated control cabinets, inverters, and chargers lack the signals required for operation and are difficult to demonstrate the operating effects of some train equipment, so they can only be used for partial functional training.
[0032] Based on this, this application provides an electrical condition cabinet and a comprehensive train electrical training system. The electrical condition cabinet includes a cabinet body, a panel, multiple electrical modules, a voltage regulation module, and multiple condition indicator devices. The multiple electrical modules and the voltage regulation module are disposed inside the cabinet body. The output terminals of the multiple electrical modules are connected to the corresponding first train equipment in the comprehensive electrical control cabinet of the train car. The output terminal of the voltage regulation module is connected to the inverter and charger of the train car. The multiple condition indicator devices are disposed on the panel, and the input terminals of the condition indicator devices are connected to the output terminals of the corresponding second train equipment in the comprehensive electrical control cabinet. The multiple electrical modules generate the target signals required by the comprehensive electrical control cabinet of the train car. The voltage regulation module generates the voltage signals required by the inverter and charger of the train car. The condition indicator devices receive the condition signals output by the second train equipment to display the condition of the second train equipment, thereby enabling the linkage operation training between the comprehensive control cabinet, the charger, and the inverter, as well as displaying the condition of multiple train equipment, intuitively understanding the role and principle of each part of the train equipment in the entire train car, and efficiently carrying out various operation exercises.
[0033] Please refer to Figure 1 , Figure 1 A schematic diagram of the electrical condition cabinet described in an embodiment of this application is shown; as follows: Figure 1 As shown, the electrical condition cabinet includes a cabinet 100, a panel 101, various electrical modules, a voltage regulation module, and various condition indication devices;
[0034] The various electrical modules and voltage regulation modules are installed inside the cabinet 100; the output terminals of the various electrical modules are connected to the corresponding first train equipment in the electrical integrated control cabinet of the train car; the output terminal of the voltage regulation module is connected to the inverter and charger of the train car; the various operating condition indication devices are installed on the panel 101, and the input terminal of the operating condition indication devices is connected to the output terminal of the corresponding second train equipment in the electrical integrated control cabinet.
[0035] The electrical integrated control cabinet, inverter, and charger mentioned are not the same electrical integrated control cabinet, inverter, and charger installed in the actual train car. Rather, they refer to electrical integrated control cabinets, inverters, and chargers with the same logic as those in a real train car, used for vehicle electrical engineering training. Their specific structure can be adapted to meet the training needs.
[0036] In the electrical control cabinet, the various electrical modules are used to generate the target signals required by the integrated electrical control cabinet of the train carriage;
[0037] The voltage regulation module is used to generate the voltage signals required by the inverter and charger of the train carriage;
[0038] The operating condition indication device is used to receive the operating condition signal output by the second train equipment in order to display the operating condition of the second train equipment.
[0039] The operation of the electrical integrated control cabinet, charger, and inverter requires signals from other external devices to ensure the system's integrity. These missing target signals are all provided by the operating condition cabinet simulation.
[0040] In this embodiment of the application, it is particularly important to note that the voltage regulation module provides the voltage signals required by the inverter and charger of the train car.
[0041] Specifically, the charger and inverter require DC600V to operate. The required voltage is relatively high and the power is relatively large. To operate normally, a separate DC600V power supply cabinet is needed. Otherwise, it will only be used for visual inspection and disassembly for learning purposes, and no power-on test will be performed.
[0042] Based on this, in this embodiment of the application, a voltage regulation module is designed in the operating cabinet, and a DC600V voltage signal is obtained by modulation through the voltage regulation module and connected to the charger and inverter. The normal operation of the charger and inverter can be achieved without the need for a separate DC600V power supply cabinet.
[0043] Specifically, the operation of a charger and an inverter requires signals such as input voltage, intermediate voltage, and output voltage. The electrical condition cabinet described in this application uses a voltage regulation module to simulate the input voltage, intermediate voltage, and output voltage of the charger and inverter.
[0044] Furthermore, the voltage regulation module can also simulate undervoltage and overvoltage faults in the input, intermediate, and output voltages of chargers and inverters.
[0045] For example, the charger and inverter receive the DC600V input voltage signal output by the electrical condition cabinet, and respond to the training operation (start operation, etc.) after being powered on.
[0046] The various electrical modules provide the target signals required by the integrated electrical control cabinet of the train carriage; specifically, one of the various electrical modules includes a temperature sensor and a potentiometer to simulate and generate a temperature signal.
[0047] The temperature signals refer to various temperature signals from the electrical integrated control cabinet, including, for example, the interior and exterior temperatures of the vehicle, the air conditioning temperature, and the axle temperature. For example, the electrical integrated control cabinet receives a temperature signal simulated by the electrical operating condition cabinet and disconnects based on the temperature signal.
[0048] In addition to the models required for the electrical integrated control cabinet, inverter, and charger of the simulated train carriage, the operating condition cabinet can also collect signals from the integrated control cabinet, charger, and inverter; it can also collect signals output from components such as circuit breakers, knobs, relays, and contactors inside the integrated control cabinet, charger, and inverter through wiring, process them through the PLC, and then transmit them to the terminal equipment for processing and storage.
[0049] The operating condition indicator device is used to display the operating conditions of various train equipment, specifically the operating conditions of passenger compartment lighting equipment, electric heating equipment, sockets and doors, as well as the operating conditions of various electrical equipment and the operating conditions of air conditioning units.
[0050] In this embodiment of the application, the panel 101 of the electrical condition cabinet includes a first region 1011, a second region 1012, and a third region 1013; please refer to... Figures 2-4 , Figure 2 A schematic diagram of the first region 1011 of the panel 101 is shown; Figure 3 A schematic diagram of the second region 1012 of the panel 101 is shown; Figure 4 A schematic diagram of the third region 1013 of the panel 101 is shown.
[0051] like Figures 2-4 As shown, the operating condition indicator device includes a plurality of first indicator lights disposed in a first area 1011, a plurality of second indicator lights disposed in a second area 1012, a first motor and a first grid terminal, and a third indicator light disposed in a third area 1013, a second motor and a third grid terminal.
[0052] The first indicator lights in the first area 1011 are respectively connected to the operating status signal output terminals of the passenger compartment lighting equipment, electric heating equipment, sockets and doors in the electrical integrated control cabinet;
[0053] The second indicator lights in the second area 1012 are respectively connected to the operating status signal output terminals of multiple electrical devices in the electrical integrated control cabinet; the power supply terminal of the first motor is respectively connected to the power supply terminals of multiple electrical devices; and the first grid terminal is respectively connected to the voltage output terminals of multiple electrical devices.
[0054] The third indicator light in the third area 1013 is connected to the air conditioning unit in the air conditioning unit in the electrical integrated control cabinet; the power supply terminal of the second motor is connected to the power supply terminals of multiple air conditioning units respectively; the second grille terminal is connected to the voltage output terminal of the air conditioning unit.
[0055] The first indicator light in the first area 1011 is used to respond to the operating condition signals corresponding to the passenger compartment lighting equipment, electric heating equipment, sockets and doors, and to simulate and display the operating conditions of the passenger compartment lighting equipment, electric heating equipment, sockets and doors.
[0056] The second indicator light and the first motor in the second area 1012 are used to respond to the second target signal corresponding to various electrical devices, simulating and displaying the operating conditions of various electrical devices; the first grid terminal is used to measure the voltage value output by the various electrical devices. The first motor is connected to the power supply terminals of multiple electrical devices, which can display the phase sequence of the AC power supply to the electrical devices and show whether the wiring is correct.
[0057] Please refer to Figure 3 The various electrical devices include a water heater, an electric boiler, a toilet, a first heat tracing device, a second heat tracing device, and a waste exhaust fan.
[0058] The third indicator light and the second motor in the third area 1013 are used to respond to the operating condition signals corresponding to the air conditioning components in the air conditioning unit, and to simulate and display the operating conditions of various air conditioning components in the air conditioning unit; the second grille terminal is used to measure the second target signal corresponding to the air conditioning unit; the second motor is connected to the power supply terminals of multiple air conditioning components, and can display the phase sequence of the AC power supply to the air conditioning components, and show whether the wiring is correct.
[0059] Please refer to Figure 4 The air conditioning components in the air conditioning unit include a compressor, a fan, an electric heater, a condenser fan, etc.
[0060] The electrical control cabinet described in this application embodiment includes a panel 101 comprising three door panels, which correspond to the first region 1011, the second region 1012, and the third region 1013, respectively.
[0061] Specifically, the panel 101 is divided into a first region 1011, a second region 1012 and a third region 1013. The panel 101 includes an upper door panel corresponding to the first region 1011, a middle door panel corresponding to the second region 1012 and a lower door panel corresponding to the third region 1013.
[0062] The panel 101 is divided into three door panels, which facilitates segmented maintenance and replacement. For example, when the air conditioning unit malfunctions, only the door panels need to be removed, without removing the entire panel 101. With continuous technological advancements and product upgrades, some components of the control cabinet may need to be upgraded or replaced. The segmented design of the door panels allows operators to easily complete component replacement by simply removing the corresponding door panels.
[0063] Please refer to Figure 2 In the aforementioned electrical control cabinet, the first area 1011 is marked with a top view and a cross-sectional view of the train carriage; multiple first indicator lights in the first area 1011 are arranged on the top view and cross-sectional view according to the layout of passenger compartment lighting equipment, electric heating equipment, sockets and doors in the train carriage.
[0064] Specifically, the cabinet door panels mainly simulate the status of passenger compartment lighting, electric heating, sockets, and doors. They use a top view and cross-sectional view of a carriage and different models of first indicator lights to show the location and working status of each device.
[0065] The PLC in the control cabinet collects the action data of the components in the integrated control cabinet and the output voltage data of the integrated control cabinet. According to the actual control logic, the PLC program is written to control the on / off state of the door panel indicators, thereby displaying the operating status of each lighting, socket, and electric heating device.
[0066] The working condition panel 101 uses a top view and cross-sectional view of the carriage, along with indicator lights, to display the working conditions of lighting, sockets, electric heating, etc., so as to intuitively understand the role of each part in the whole carriage.
[0067] Please refer to Figure 3 The middle door panel of panel 101 mainly simulates the working conditions of various electrical devices on the vehicle through the second indicator light and the first motor, and can measure the device voltage through the lower black grille terminal.
[0068] The first motor is a 24V motor. The operation results of the first motor can verify the wiring training results of the three-phase AC power of the electrical integrated control cabinet 200. The forward and reverse rotation of the first motor can provide feedback on whether the phase sequence of the AC voltage output by the electrical integrated control cabinet 200 is correct.
[0069] For the second indicator light and the first motor, the PLC in the electrical control cabinet 100 collects the corresponding circuit breaker signals and outputs control signals to the second indicator light and the first motor, so that the second indicator light and the first motor operate under the control of the control signals. The grid terminal connects the output voltage of the electrical equipment directly from the interface of the integrated control cabinet, facilitating voltage measurement. A multimeter can be used for specific measurements.
[0070] Please refer to Figure 4 In the electrical control cabinet, the third area 1013 is marked with the internal schematic diagram of the air conditioning unit; the third indicator light, the second motor, and the second grille terminal are arranged at the positions corresponding to the air conditioning components in the internal schematic diagram.
[0071] The lower panel of the electrical condition cabinet 101 simulates the working condition of the air conditioning unit. Using the internal schematic diagram of the air conditioning unit as a background, the second motor and the third indicator light are used to simulate the internal working condition of the unit. The voltage can be measured through the grid terminals. The forward and reverse rotation of the second motor can provide feedback on whether the phase sequence of the AC voltage output by the integrated control cabinet is correct.
[0072] The operating panel 101 uses the air conditioning unit schematic diagram along with the motor and grille terminals to display the entire air conditioning unit. By operating the air conditioner under different conditions, and by combining the motor rotation with the unit schematic diagram, the air conditioning principle can be understood more intuitively.
[0073] The third indicator light and the second motor are also controlled by the PLC by collecting the corresponding circuit breaker signals and outputting control signals. Similarly, the grille terminals connect the air conditioning unit's output power directly from the interface of the electrical control cabinet for convenient voltage measurement.
[0074] In summary, the control panel 101 of the embodiment of this application is provided with a top view and cross-sectional view of the carriage and a schematic diagram of the air conditioning unit. The relevant components are arranged on the panel 101 in a corresponding layout, which makes it easier for trainees to understand the corresponding functions and principles more intuitively.
[0075] In some embodiments, the electrical condition cabinet further includes a circuit fault setting module;
[0076] The circuit fault setting module is used to trigger faults in the electrical integrated control cabinet, charger, and inverter.
[0077] Specifically, the circuit fault setting module includes multiple relay circuits; the multiple relay circuits are connected in series in the circuits of the electrical integrated control cabinet, the charger, and the inverter, respectively, and the relay contacts in the relay circuits open or close to trigger a fault.
[0078] Common faults in various components of the electrical integrated control cabinet, charger, and inverter are incorporated into the circuits of the integrated control cabinet, charger, and inverter. The normally open or normally closed contacts of the relays are triggered by the PLC, thereby setting faults in the circuits of the integrated control cabinet, charger, and inverter through the operating condition cabinet, to conduct common fault diagnosis and maintenance training.
[0079] Based on the same inventive concept, this application also provides a train electrical engineering integrated training system corresponding to the electrical condition cabinet. Since the principle of solving the problem in the train electrical engineering integrated training system in this application is similar to that of the electrical condition cabinet in this application, the implementation of the train electrical engineering integrated training system can refer to the implementation of the electrical condition cabinet, and the repeated parts will not be described again.
