step S2, based on the operation of a user on the virtual electric key, the virtual electric key is in an activated state, and then a plurality of virtual operation keys are in an operable state;
and step S3, a virtual instruction is sent based on the operation of the plurality of virtual operation keys by a user, so that the cab-free power vehicle executes corresponding actions.
In some embodiments, the cab-less power vehicle may be determined to be in a non-consist state based on a number of vehicle nodes of the train communication network being 1. It may be determined whether the current powered vehicle is a cab-less powered vehicle based on the hard-wire code. In an embodiment of the present invention, "in an operable state" may mean that the virtual electric key may be activated in response to an operation thereof by a user, or the virtual operation button may transmit a virtual instruction in response to an operation thereof by a user. The plurality of virtual operating buttons are in an operable state only after the virtual electric key is activated. In contrast, the "in an inoperable state" means that the virtual electric key is not activated even if the user operates the virtual electric key, or the virtual operation button does not transmit a virtual instruction even if the user operates the virtual operation button.
In some embodiments, the action performed by the dripless power vehicle includes one or more of: the power mode of the non-driver power vehicle is switched, the running direction of the non-driver power vehicle is controlled, and the maintenance test of the non-driver power vehicle is performed. Therefore, in the non-marshalling state, the virtual control interface and the virtual control part are arranged in the power vehicle without the cab, so that the problem that a single power vehicle cannot be independently tested and controlled in running is solved.
Fig. 2 is a schematic diagram of a virtual operation interface according to an embodiment of the present invention, as shown in fig. 2, the virtual operation interface may be a display screen, on which a virtual electric key and a plurality of virtual operation keys are disposed, where the virtual operation keys may include, for example: a start key associated with starting the engine, a put key and an isolate key associated with controlling the engine, an internal combustion mode key and an electric power mode key associated with the power mode, a forward key associated with the direction, a neutral key and a reverse key, and an indication key associated with the handle level. The user can operate the virtual electric key and the plurality of virtual operation keys by touching, clicking, or the like.
In some embodiments, the method further comprises: based on the fact that the cab-free power vehicle is in a non-grouping state, the node where the cab-free power vehicle is located serves as a main node of a train communication network, and therefore the cab-free power vehicle can have the capability of controlling functions of the cab-free power vehicle in the non-grouping state.
In some embodiments, the method further comprises: and switching the node where the cab-free power vehicle is located from a master node to a slave node based on the fact that the cab-free power vehicle is switched from a state where no other power vehicles occupy the group to a state where the rest power vehicles occupy the group. Therefore, under the grouping state, the cooperative control of the cab-free power vehicle at the head and tail ends is realized by reducing the grouping master control authority of the cab-free power vehicle.
In some embodiments, the method further comprises:
based on the cab-less power vehicle being in a marshalling state and all cabs of the motor train unit being in a non-occupied state, the virtual electric key is in an operable state;
based on the operation of the user on the virtual electric key, the virtual electric key is in an activated state, and then a plurality of virtual operation keys are in an operable state;

It may be determined that all cabs are in a non-occupied state based on that keys of all cabs are not inserted. The virtual electric key can be in an activated state, so that the node where the cab-less power vehicle is located is used as a master node of a train communication network. Therefore, the motor train unit can be controlled by taking the cab-free power vehicle as the main control end of the whole motor train unit under the condition that the cab-free power vehicle is in a marshalling state and all cabs of the motor train unit are in a non-occupation state, the control range of the cab-free power vehicle is further expanded, and the control mode of the motor train unit is more various and flexible.

In some embodiments, the cab-less power vehicle includes a central control unit, the method further comprising:
the central control unit judges the type of the self-powered vehicle;
based on the fact that the power vehicle is a cab-free power vehicle, the central control unit receives the virtual instruction and sends the virtual instruction to the motor train unit.
Therefore, the virtual command can be sent to the motor train unit after being sent from the cab-free power vehicle, and the influence of interference signals is avoided.
In some embodiments, the method further comprises: and based on the fact that the cab-free power vehicle is in a marshalling state and the cabs of the motor train unit are in an occupied state, the virtual electric key and the virtual operation keys are in an inoperable state. When the cab-less power vehicle is in a marshalling state and the cabs of the motor train unit are in an occupied state, the cab-less power vehicle should serve as a slave control end, and the virtual electric key and the virtual operation key are set to be in an inoperable state, so that control signals which collide with the master control signals are avoided.
Fig. 3 shows a signal communication flow chart according to an embodiment of the present invention, as shown in fig. 3, a microcomputer display screen of a cab-less power vehicle may collect corresponding signals and transmit the signals to a central control unit through a communication means such as ETH (ethernet) +mvb (multi-function vehicle bus). The central control unit is responsible for receiving the virtual instruction signal and checking the validity of the signal. And then, the cab-free power vehicle is controlled through the command signal, and the command is transmitted to the whole train unit through WTB (wire train bus) communication.
The microcomputer display screen is responsible for signal acquisition, for example, when the whole train of motor cars has other power cars in a cab occupied state, the virtual electric key is forbidden to be activated, and all other virtual command operation signals are in a forbidden enabling state. Such as keyless occupancy of the entire train, allows activation of the virtual electric key signal via the display. When the virtual electric key signal is activated, the virtual command operation signal is enabled. The virtual starting signals are pulse signals, and the virtual electric key, the virtual machine control switch, the virtual power mode switch, the virtual direction and the virtual handle level are level signals.
After receiving the virtual operation instruction, the microcomputer display screen transmits the instruction to the central control unit in an ETH+MVB mode. When the virtual key is activated, the virtual machine control switch closing position, the internal combustion power position of the virtual power mode switch, the virtual direction neutral position and the virtual handle level position 0 are automatically transmitted by default. Meanwhile, when each virtual instruction is sent, the valid bit of the corresponding instruction is sent, so that signal transmission accuracy is ensured, and false sending of virtual signals caused by communication interference is prevented.
The central control unit is responsible for receiving virtual instruction signals from the microcomputer display screen. The central control unit judges the type of the power vehicle, and if the power vehicle is the power vehicle with the cab, the virtual instruction signal of the display screen is not adopted. If the vehicle is a power vehicle without a cab, receiving a virtual instruction signal of a microcomputer display screen. Meanwhile, the power vehicle is operated through logic processing to realize the functions of self-loading, switching of the electric modes in the whole train motor train unit, power test and the like.
The existing dripless power vehicle usually adopts a hard line through connection mode in the process of grouping, a microcomputer meets the operation function of the whole locomotive row through a hard line instruction, and if a single locomotive is not grouped, the function verification of the locomotive cannot be completed. In the embodiment of the invention, the train-level network control function of the motor train unit is finished by adopting a communication mode of the WTB network, and when the motor vehicles without cabs are matched in a grouping way, the type, the power source and the grouping address of the motor vehicles are identified by designing a penetrating connector and configuring a combined coding rule of a WTB network communication line and a hard line.
The specific rules are as follows:
and setting a WTB network communication gateway and a double-path redundant WTB train pass-through line, and carrying out network initial operation configuration through an UIC protocol to dynamically identify the grouping address and master-slave control nodes of each section of power vehicle. The cab-free judgment is realized through the hard wire combination coding, and the type identification of the internal combustion power and the electric power is realized.
When the motor train unit is not connected, the single-section power vehicle without the cab is identified by combining the vehicle number setting through hard wire configuration, and meanwhile, comprehensive judgment is carried out by combining the number of vehicle nodes after the WTB is operated initially as 1, so that the current power vehicle is determined to be a single section. After the conditions are met, the cab-free power vehicle can be virtually activated to serve as a limited main control node, and the limited main control node can realize the functions of power mode switching, direction change, maintenance test and the like of a single-section power vehicle.
If the cab-free power vehicle is in the restricted main control node, the remaining cab occupation of the train changes, the microcomputer can automatically control the vehicle of the section to withdraw from the key occupation, all functions are restored to the default state, and after the main control occupation of the key node is completed again by the train, the main control node at the occupation end is listened to perform test and operation.
When the key node occupation of the power car with the cab is effective after the motor train unit is hung, the power car without the cab cannot activate the virtual key operation, so that the whole train is ensured not to influence the operation due to master control competition caused by key conflict.
Fig. 4 is a schematic diagram of a WTB node address sequence of an internal electric dual-source power centralized motor train unit in an embodiment, in a train consist, after each power-up of a microcomputer, the motor train unit should complete a TCN (train communication network) initial operation process, and a microcomputer central control unit can identify whether the motor train unit is a WTB master device, is in the same direction as or opposite to the direction of the master device, and includes a node address, a node number, and a bottom node address.
And each time the TCN initial operation is completed, the microcomputer central control unit is based on the TCN initial operation result and identifies other operation instructions, so that node index, node identification, master control vehicle identification and train direction identification are realized. Wherein only one cab electric key signal is activated, and the activated power vehicle is a master control vehicle. The other power vehicles are slave vehicles in the marshalling, receive the control instruction of the master vehicle, and feed back state information and the like. The cab electric key signal activation condition is that the electric key signal is triggered by a rising edge and is held high. In fig. 4, the microcomputer central control unit can dynamically control the cab-free fuel-powered vehicle to be a master control vehicle in real time through a microcomputer display screen virtual key occupation signal.
Fig. 5 shows a software flow chart for setting the host vehicle as a cab-less power vehicle in the main control program of the microcomputer central control unit. As shown in fig. 5, it may be determined that the host vehicle is permitted to be set as a cab-less power vehicle through the display screen based on the following conditions: the CCU (central control unit) is a main device (but not a redundant auxiliary device), the hard-wire signal indicates that the current state of the power vehicle without the cab and the diesel engine is a stop state, the state of the pantograph in the whole row is a descending state, and the locomotive speed is zero. That is, in the case where it is determined that the host vehicle is a cab-less power vehicle, no power is generated (no diesel engine is started, no power is supplied), and the locomotive speed is zero, the host vehicle is allowed to be set as a cab-less power vehicle. Unsafe setup during locomotive operation is avoided.
When the microcomputer central control unit successfully sets the model of the power vehicle according to the method in fig. 5, the state of the model of the power vehicle is automatically stored in the ferroelectric area, and the model of the power vehicle can be directly read after the microcomputer is electrified again each time. Meanwhile, if the microcomputer judges that the ferroelectric stored power vehicle type number state is inconsistent with the power vehicle type hard line signal, a microcomputer display screen can automatically prompt a driver of 'wrong setting of the CCU power vehicle identification of the vehicle'. If the microcomputer judges that the model states of the power vehicles stored in the ferroelectric memory of the master CCU and the slave CCU are inconsistent, a microcomputer display screen can automatically prompt a driver that the marks of the power vehicles of the CCU of the host vehicle are inconsistent.
Fig. 6 shows a schematic view of a virtual manipulator 10 of a cab-less power vehicle according to an embodiment of the present invention, and as shown in fig. 6, the virtual manipulator 10 includes:
a virtual operation interface 12 on which a virtual electric key and a plurality of virtual operation keys are provided;

and sending a virtual instruction based on the operation of the plurality of virtual operation keys by a user, so that the cab-free power vehicle executes corresponding actions.

The motor train unit adopts an internal electric split design structure, the whole train consists of an electric power vehicle, a trailer and an internal combustion power vehicle, and the electric power vehicle and the internal combustion power vehicle are respectively arranged at two ends of the motor train unit. In any cab, a crewmember can select an internal combustion mode or an electric mode to respectively activate a corresponding internal combustion power vehicle or an electric power vehicle to exert traction power, so that internal power and electric power double-source mutual control is realized. Meanwhile, the whole train of motor train units has the characteristics of multi-network fusion and data communication, and state data of any section of whole train of motor train units can be monitored on an internal combustion motor vehicle, a trailer and an electric motor vehicle in real time. The internal electric double-source power centralized motor train unit is suitable for a high altitude operation environment in a plateau region, and can solve the problem that when a single power mode is adopted, the power of a single-section internal combustion motor vehicle or an electric motor vehicle cannot meet the climbing capacity of a high altitude large ramp. Of course, in other embodiments, other forms of motor train units may be employed.
