Generally, a motor train unit with 8 groups is equipped with 1 driver; a 16 consist would be equipped with 2 on-board machinists.

The structures of the vehicle cab, the end vehicle body, the vehicle body and the like, and the solid mechanical structures in the modules are manufactured in a simulation mode with the corresponding structure 1:1 of the real motor train unit or directly adopt real vehicle original parts, so that the associated mechanical structures in the modules have the same mechanical linkage capacity as the real motor train unit.
In the actual layout, the vehicle cab, the end vehicle body and the vehicle body respectively provided with the equipment module in the roof equipment module can be arranged independently and dispersedly (as shown in fig. 3); or according to a real vehicle layout (as shown in fig. 4 and 5). However, the real object equipment unit is provided with a set of electrification control system with the same control logic as the real motor train unit, and part of control components in the train end equipment module, the train roof equipment module and the in-train equipment module are in electrical communication connection with part of control components in the simulated driving module, so that the simulated driving module has the highest priority control right in the real object equipment unit.

Example 2
The embodiment of the application provides a method for multi-worker linkage training by adopting the motor train unit linkage simulation training system provided by the embodiment 1.
In this embodiment, the instructor selects, by the teaching management unit, a pantograph foreign matter hanging course in the abnormal driving handling course classification. The lesson involves the coordination of multiple work classes in multiple work stations, such as trainee drivers, trainers, train conductors, motor train dispatchers (station attendants), and the like. Since the train conductor and the motor train dispatcher (station attendant) have less operation content in the course, the work of the work is simulated and replaced by the AI module in the virtual simulation unit.
The teaching management unit transmits the related data information to the core control unit through communication connection, the core control unit processes the related data information to form a control instruction of the state of the corresponding control component/virtual operation component in the physical equipment unit and the virtual simulation unit, and the teaching management unit executes the action corresponding to the instruction at the corresponding control component/virtual operation component through communication connection to change the state of the control component/virtual operation component. The state change of the relevant control component/virtual operating component is converted into data information by the prior art means and transmitted to the core control unit through the communication connection. The core control unit compares the data information with the corresponding data information transmitted by the teaching management unit to judge whether the relevant control component/virtual operation component meets the initial state required by the course.
In the course, a scene module in the virtual simulation unit is controlled by the core control unit, generates and displays corresponding views, lines, vehicles and positions through the environment simulation component, and generates and displays the initialization state of each device in the vehicle through the device simulation component. In the implementation, the environment simulation component outputs a state that a motor train unit is parked in a station and waits for the motor train unit to come out of the station, and the motor train unit is in a static state; the equipment simulation assembly outputs an equipment state for displaying that the parking brake is applied and each equipment in the vehicle is not powered, and meanwhile, the corresponding virtual operation component in the operation module is controlled by the core control unit and presents a working state consistent with the display state of the equipment simulation assembly; the text output component outputs a presentation of text associated with a lesson scene awaiting entry by a trainee mechanic using the virtual reality device. At the moment, a student mechanic can enter the virtual simulation unit, and can realize the perception of the scene module and the AI module and the operation of the operation module by wearing VR glasses and necessary body sensing equipment.
Meanwhile, the simulated driving module in the physical equipment unit is controlled by the core control unit to generate the initial state of the physical equipment matched with the state of each virtual operating component in the upper operating module. The vehicle-end equipment module, the vehicle roof equipment module and the vehicle interior equipment module are controlled by the core control unit, and the core control unit or the physical equipment unit or the PLC logic control device in each module drives the corresponding physical equipment to move so as to achieve a course initialization state. In the implementation, the forward visual view of the driving simulation module displays that the motor train unit is parked in a station and waits for the motor train unit to come out of the station, the motor train unit is in a static state, all buttons and pull keys on a driving control console are in initial positions, and equipment is not powered; an automatic coupler in the car end equipment module is in a telescopic position, and a front end cover is in a locking position; the main circuit breaker of the roof equipment module is at a breaking position, and the pantograph is in a non-pantograph-rising state; the in-vehicle electrical device of the in-vehicle device module is in an unpowered state. The trainee driver can enter the vehicle cab to prepare for operation of the various operating components of the analog driver module.
Thus, the preparation work before the course is started is automatically finished.
After the course begins, a student driver closes a key at the driving simulation module, a direction knob switch selects forward movement, a storage battery knob is pulled to open position, a main circuit breaker pull knob is arranged at the closed position, a pantograph pull knob is arranged at the pantograph lifting position to relieve and stop braking, a traction handle is pushed after air inflation, the motor train unit begins to advance, and the front view changes correspondingly along with the change of the position of the motor train. And in the process that a student driver operates the control component, the state data change information of the control component is sent to the virtual simulation unit by the core control unit through a real-time data transmission protocol. And the virtual simulation unit receives the data and drives the virtual operation part corresponding to the control part to reach the same action state as the physical equipment unit by a self-defined data analysis method.
And the state change data of the control component operated by the student driver at the driving simulation module is sent to other modules except the driving simulation module in the material object equipment unit through the core control unit. The partial data is converted into corresponding high and low level signals through a PLC logic control unit, the signals drive an automatic coupler in a car end equipment module to be in a recovery position, and a front end cover is in a locking position; closing a main breaker of the roof equipment module, and lifting a pantograph; the vehicle-mounted electrical equipment of the vehicle-mounted equipment module is powered on and is attracted by the related relay.
And the student driver continues driving operation until the student driver reaches a fault trigger site set by the teaching management unit for the course, at the moment, the event module in the core control unit judges that the motor train unit reaches a fault trigger place, sends fault data preset in the course to a forward visual scene of the simulation driving module through a command transmission protocol, and displays foreign matters on a contact network. Meanwhile, the instruction data is also sent to the virtual simulation unit so as to realize that the output content of the environment simulation assembly of the virtual simulation unit conforms to the forward view of the driving simulation module.
The student driver operates the relevant control component at the driving simulation module according to the operation flow, so that the pantograph of the roof module is lowered, and the forward vision and environment simulation component of the driving simulation module displays the parking state. The state change data of the control component caused by the operation of the trainee driver is sent to the virtual simulation unit by the core control unit through a real-time data transmission protocol. The virtual simulation unit receives the data and drives the corresponding virtual operation component to reach the same action state as the physical equipment unit through a self-defined data analysis method. That is, the virtual roof device lowering pantograph is shown at the device simulation component of the virtual simulation unit. The control component is positioned in the simulated driving module, and the change of the state of the control component is controlled by the mechanical and electrification in the physical equipment unit, so that the pantograph of the roof equipment module and the vehicle-mounted equipment module is lowered, and the main circuit breaker is disconnected with the relay related to the vehicle-mounted electrical equipment, so that the vehicle-mounted electrical equipment is disconnected and loses power.
Then, the trainee driver reports and informs the driver of the vehicle-mounted mechanic to the motor car dispatcher (station attendant) through the vehicle-mounted telephone in the simulation driving module. The report content is converted into corresponding characters through a voice recognition technology and displayed at a scene module of the virtual simulation unit. At this time, the student mechanic can see the corresponding characters through the VR glasses worn by the student mechanic. The state change data is sent to the core control unit through a real-time data transmission protocol, and after being processed by the core control unit, a lesson student mechanic training lesson content data instruction is triggered. After a period of time, the AI module simulates a motor train dispatcher (station attendant), sends a dispatching command that the overhead line system has power failure and permits the on-line operation and a verbal instruction that the dispatching command below the speed limit of the adjacent line train is issued, and responds to the content reported by the trainee drivers. Subsequently, the trainee mechanic applies for the driver to get off the vehicle through the sound pickup device worn by the trainee mechanic. The voice information is converted into characters through a voice recognition technology, and the characters are processed, transmitted and sent to a forward view of the driving simulation module by the core control unit.
After receiving the response and the application, the student driver operates a button on the driving simulation module to cut off the pantograph hung with the foreign matters and then raises another good pantograph, and the vehicle screen of the driving simulation module confirms that no network voltage exists and carries out discharging. The student mechanic walks at the virtual simulation unit, the student mechanic is displayed to go to a mechanic room or a driver room through the scene module through data transmission of the somatosensory device and the operation module and a self-defined data analysis method in the virtual simulation unit, and no network voltage is confirmed through a vehicle screen at the device simulation assembly. The student driver informs the student mechanic to get off the bus through the interphone in the simulation driving module, the voice information is converted into character information, and the character information is displayed to the student mechanic through the character output assembly. And the state change data of each control component and each virtual operation component is sent to the core control unit through a real-time data transmission protocol, and after the state change data is processed by the core control unit, a subsequent content data instruction in the course is triggered. The practical expression is that scene module department show scene takes place to switch, and student's mechanologist makes scene module department show through the walking and walks to door department for student's mechanologist, through the cooperation of virtual operation part among its body sensing equipment of wearing and the operating module, opens by environment simulation subassembly show operation door, by non-adjacent line side get off. The opening state of a virtual operation component, namely the door, in the operation module is sent to the simulated driving module through the core control unit, and the state of the corresponding door is displayed as an opening position on a vehicle screen at the simulated driving module.
In order to improve the implementation ability of the student mechanic, when the environment simulation assembly shows that the operation vehicle door is opened and the student mechanic gets off from a non-adjacent line, the state data is transmitted to the core control unit through real-time data to trigger a subsequent content data instruction in the course. In practice, the text output component displays text and prompts a student mechanic to transfer to the roof equipment unit for operation. After receiving the text prompt, the student mechanic takes down the VR glasses and the body sensing devices, walks to a roof operation platform beside a carriage where the roof equipment unit is located, wears safety helmets, insulating gloves and insulating shoes, erects the grounding rod, confirms that a contact network has a power failure and a motor train unit has finished discharging by using an electricity testing rod, and removes pantograph foreign matters on the non-meeting side by using an order rod (insulating rod). The operation of the student mechanic is to take multi-angle pictures through a plurality of cameras at the operation positions, and the existing action recognition technology is used for comparing and analyzing with standard operation action data prestored in the teaching management unit, so that automatic evaluation is performed.
After the student mechanic removes the pantograph foreign matter, the insulating device is recovered, the student returns to the virtual simulation unit, clicks the completion/incompletion of the step, and triggers the subsequent content data instruction in the course after the core control unit receives the data. The practical expression is that after the mechanical teacher clicks the next step, the mechanical teacher informs the mechanical teacher to cut off the failed pantograph by the interphone, and the mechanical teacher can normally operate with the good pantograph. Meanwhile, the trainee mechanic reports the information that the fault is processed to the local motor car dispatcher (station attendant) at the place where the fault is located. The state change data is sent to the core control unit through a real-time data transmission protocol, and after being processed by the core control unit, a lesson student mechanic training lesson content data instruction is triggered. The practical expression is that after a period of time, an AI module simulates a motor car dispatcher (station attendant), issues information that the motor car dispatcher and a power supply dispatcher handle the power transmission procedure of a contact network, informs a train in the power failure and power supply arm to lift a pantograph, cancels adjacent line speed limit and restores normal driving. The release content is text information and is displayed in a forward view of the driving simulation module. After seeing the message, the trainee driver raises the bow again, closes the main breaker and continues to operate the vehicle normally. The corresponding control component in the physical equipment unit acts to the correct position along with the physical equipment unit, and the corresponding virtual operation component in the virtual simulation unit is regulated and controlled by the core control unit to be in state synchronization. By this point, the entire course ends.
The teaching management unit evaluates the control process of a trainee driver and a trainee mechanic through real-time data feedback of the core control unit and by combining preset evaluation data information. The specific evaluation may be expressed as: if the fact that the foreign matter of the pantograph is removed when a mechanical teacher of a student does not wear insulating equipment is recognized in the image shot by the camera, a failure item is triggered, and the teaching management unit displays the view of the student for the exercise or the examination, wherein the view is unqualified; and if the non-lattice-losing item is not judged to be correct according to the corresponding flow step, evaluating and giving a detailed evaluation report.
The course selected by the embodiment of the application is a whole vehicle scene training course. The instructor can select only the participating modules needed in the linked physical equipment units at the teaching management unit. And after the selection is completed, the core control unit receives the course data issued by the teaching management unit and controls and monitors the components in the corresponding modules. The control component in the physical equipment unit which is not involved can not be controlled by personnel except the mechanical and electrical control association relation with the simulation driving module; the virtual operation component in the corresponding virtual simulation unit is controlled by the core control unit to obtain the operation authority. Therefore, even though the instructor does not select all the physical equipment to participate in linkage or is limited by the field and other factors and does not attach the physical equipment of the whole motor train unit, the physical equipment of the whole motor train unit can be supplemented by the virtual simulation unit, so that the finished whole motor train unit is formed, and training of related courses is realized.
