Description

Technical Field

[0001] The present invention relates to the technical field of rail train control, and in particular to a switching control method, device and system based on the separability of a chassis and a carriage. Background Art

[0002] At present, for multi-unit trains, mixed passenger and freight transportation can be achieved regardless of whether variable unitization or separation of passenger and freight cars is adopted. Among them, the method of using variable unitization to achieve mixed passenger and freight transportation is actually to use some cars in the same unit for passengers and some cars for freight. In the daytime operation environment, the operation mode of mixed passenger and freight transportation requires the design of a separate loading and unloading work section on the platform, and the current station needs to be redesigned, which makes it difficult to take into account both passenger safety and freight transportation efficiency. In addition, the form of separating passenger and freight cars is just to use the original passenger car for loading. Even if the original train control scheme of the corresponding car is continued in different operation scenarios, it is difficult to achieve the special control requirements of specific equipment, resulting in poor flexibility of train control. It can be seen that both of the above two train control methods have the problem of poor flexibility, which invisibly increases the operating cost of railway resources. Summary of the invention

[0069] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below with reference to the accompanying drawings in the present invention. Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present invention without making creative efforts shall fall within the protection scope of the present invention.

It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order different from those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of the same type and do not limit the number of objects. For example, the first object can be one or multiple.

[0071] It should be understood that the terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. As used in the present invention, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include the plural forms.

[0072] The terms "include" and "comprise" indicate the presence of the described features, wholes, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, wholes, steps, operations, elements, components and / or their combinations.

[0073] Figure 1 It is the first schematic flowchart of the switching control method based on the detachable chassis and carriage provided by the present invention. As Figure 1As shown in the figure, the switching control method based on the detachable chassis and carriage provided by the embodiment of the present invention includes: Step 101, when it is determined that the first carriage communication link is in a connected state, receive the first operation mode identification information sent by the second control terminal.

[0074] Wherein, the first carriage communication link is established by the corresponding first control terminal and second control terminal for communication connection after the target carriage and the first target chassis are mechanically combined. The target carriage is one or more train carriages in the train formation, and the first target chassis is one or more train chassis in the detachable chassis corresponding to the train formation. The first operation mode identification information is determined by the second control terminal according to the operation mode corresponding to the current position of the mechanical pointer in the first mode switcher, and the first mode switcher is arranged on the first target chassis.

[0075] It should be noted that the execution subject of the switching control method based on the detachable chassis and carriage provided by the embodiment of the present invention is a switching control device based on the detachable chassis and carriage. The switching control device based on the detachable chassis and carriage can be set in the first control terminal arranged in the carriage, or the switching control device based on the detachable chassis and carriage is the first control terminal arranged in the carriage.

[0076] The application scenario of the collaborative control based on the switched operation mode is that when the rail train switches to the corresponding operation mode in different service scenarios, the internal operation environment of the carriage is also changed accordingly to adapt to the switched operation mode.

[0077] Among them, the service scenarios include but are not limited to the switching between the passenger and freight transport modes of the formation train, the switching between the corresponding passenger transport modes of the formation train under different policies, and the switching between the corresponding freight transport modes of the formation train under different carrying capacities. The embodiment of the present invention does not make specific limitations on this.

[0078] Exemplarily, the service scenario corresponding to the switching control method based on the detachable chassis and carriage can be the switching between the passenger and freight transport modes of the formation train. The corresponding operation modes include the freight transport mode and the passenger transport mode. For each carriage in the formation train, a detachable chassis is mechanically connected to the lower surface. The switching process of any train carriage (i.e., the target carriage) that needs to switch the operation mode between the two modes is essentially the replacement process of the carriage (i.e., the target carriage) of the single-formation train with a detachable chassis:

[0079] If the target carriage changes from the passenger transport mode to the freight transport mode, first separate the passenger carriage from the chassis that is currently mechanically connected. After replacing the passenger carriage with the freight carriage, mechanically connect the freight carriage to the chassis. Conversely, if the target carriage changes from the freight transport mode to the passenger transport mode, first separate the freight carriage from the chassis that is currently mechanically connected. After replacing the freight carriage with the passenger carriage, mechanically connect the passenger carriage to the chassis. The actual replacement process is more complex than the principle description and will not be elaborated here.

[0080] It should be noted that before step 101, that is, after switching the operation mode by changing the combination of the carriage and the chassis, establish a communication connection between the first control terminal on the replaced target carriage and the second control terminal on the first target chassis before replacement through the Controller Area Network (CAN) to form the first carriage communication link.

[0081] Specifically, in step 101, when the switching control device based on the detachable chassis and carriage set in the first control terminal determines that the first carriage communication link is in a connected state according to the connection feedback message interacted between the two parties, receive the first operation mode identification information sent by the second control terminal through the first carriage communication link.

[0082] Among them, the first operation mode identification information refers to the second control terminal identifying the operation mode pointed to by the mechanical pointer in the first mode switch on the first target chassis, and outputting the obtained operation mode characterization information as the first operation mode identification information to the first control terminal.

[0083] It can be understood that the memory addresses corresponding to the data collected from the carriage or chassis in different operation modes can be pre-correspondingly allocated to different gears in the first mode switch. So that in the application process, by setting the position of the mechanical pointer of the first mode switch, the relevant operation data in the corresponding operation mode can be read according to the memory address corresponding to the gear at the current position. The embodiments of the present invention do not make specific limitations on this.

[0084] Step 102: Obtain the current operation mode of the target carriage based on the first operation mode identification information and the second operation mode identification information.

[0085] Among them, the second operation mode identification information is determined by the first control terminal according to the operation mode corresponding to the current position of the mechanical pointer in the second mode switch, and the second mode switch is arranged in the target carriage.

[0086] It should be noted that before step 102, after determining that the communication link of the first carriage is in a connected state, the first control terminal simultaneously identifies the operation mode pointed to by the mechanical pointer in the second mode switch provided on the target carriage, reads the relevant operation data in the corresponding operation mode according to the memory address corresponding to the gear position of the current location, and outputs the obtained operation mode characterization information as the second operation mode identification information.

[0087] Among them, the memory address of the chassis operation data is different from the memory address of the carriage operation data.

[0088] Specifically, in step 102, the switching control device based on the detachable chassis and carriage provided in the first control terminal integrates and analyzes according to the first operation mode identification information corresponding to the chassis and the second operation mode identification information corresponding to the carriage to determine the current operation mode after the recombination of the target carriage and the first target chassis.

[0089] Step 103: When it is determined that the current operation mode is the target operation mode, generate a control instruction based on the carriage operation information.

[0090] It should be noted that before step 103, the switched operation mode needs to be recorded in the target operation mode in advance for the operation modes that can be switched set for the service scenario.

[0091] It should be noted that the carriage operation information refers to the operation information related to power consumption in the carriage except for the braking system.

[0092] The carriage operation information can be collected by sensors arranged in the carriage or determined by the response information of components that consume the power of the carriage.

[0093] Specifically, in step 103, the switching control device based on the detachable chassis and carriage provided in the first control terminal compares the currently identified operation mode in step 102 with the target operation mode set after the operation mode switch:

[0094] If the current operation mode is the same as the target operation mode, monitor the operating environment of the target carriage in the original working mode, perform control analysis using the collected carriage operation information, and obtain a control instruction for adapting the operating environment to the current operation mode.

[0095] If the current operation mode is different from the target operation mode, feedback the information of the identified abnormality to the user for corresponding processing.

[0096] Step 104: Send the control instruction to the target component module so that the target component module adjusts the operating state of the target carriage to the target operating state according to the control instruction.

[0097] Among them, the target operating state matches the target operation mode. The target component module includes the facility components in the target carriage.

[0098] It should be noted that the target component module is mainly used to control the internal scene environment of the carriage. The target component module includes, but is not limited to, the lighting system, broadcasting system, air conditioning system, etc. of the carriage.

[0099] Specifically, in step 104, the switching control device based on the separation of the chassis and the carriage set in the first control terminal sequentially sends the control signal obtained in step 103 to the target component module in the carriage.

[0100] Each component in the target component module receives and responds to the control signal, adjusts the control parameter corresponding to the component from the original value to the target value indicated by the control signal, until all the components in the target component module are adjusted. At this time, the target carriage is adjusted from the operating state of the operation and maintenance environment of the target component module to the target operating state.

[0101] Exemplarily, for the service scenario of switching between passenger and freight transport modes of a formation train, the operation list may include switching from the passenger transport mode to the freight transport mode, and setting the gear positions corresponding to these two modes in the second mode switch. Taking the carriage switching from the passenger transport mode to the freight transport mode as an example:

[0102] Before the train runs, set the mechanical pointer of the second mode switch at the position corresponding to the freight transport mode, and set the freight transport mode as the target operation mode to complete the mode switching, but the internal environment of the carriage still operates in the manner corresponding to the original passenger transport mode.

[0103] During the train operation, after the first control terminal identifies that the current operation mode is the freight transport mode and is consistent with the freight transport mode indicated by the target operation mode, it collects the carriage operation information of the target component module in the target carriage under the operating environment corresponding to the original operation mode, generates a control instruction, and adjusts the operation of the target component module in the target carriage to be adapted to the current freight transport mode through the control instruction.

[0104] In the embodiment of the present invention, when the communication between the carriage and the chassis is good, by receiving and responding to the first operation mode identification information reported by the control end of the chassis, and combining the second operation mode identification information to determine the current operation mode. When the current operation mode is the target operation mode after mode switching, it is decided to generate corresponding control instructions through the carriage operation information to control the target component module to adjust the operation situation of the carriage environment to be adapted to the target operation mode. It can automatically switch the control logic in different operation scenarios, make adaptive modifications to the carriage operation environment through personalized and differentiated collaborative control for different carriages, improve the operation flexibility and adaptability of the train, and reduce the train operation cost.

[0105] Based on the above any embodiment, obtaining the current operation mode of the target carriage based on the first operation mode identification information and the second operation mode identification information includes: when it is determined that the first operation mode identification information and the second operation mode identification information are different, obtaining the current operation mode of the target carriage based on the second operation mode identification information.

[0106] Specifically, in step 102, the switching control device based on the detachable chassis and carriage set in the first control terminal compares the first operation mode identification information corresponding to the chassis with the second operation mode identification information corresponding to the carriage:

[0107] If the first operation mode identification information and the second operation mode identification information are different and both are valid, that is, it can be determined that the chassis operates normally in the operation mode after switching through the first operation mode identification information at the correct memory address, and it can also be determined that the carriage operates according to the operation mode after switching through the second operation mode identification information corresponding to the target operation mode. Then, directly use the corresponding relationship between the first operation mode identification information and the operation mode to determine the current operation mode of the target carriage.

[0108] If the first operation mode identification information and the second operation mode identification information are different, but at least one of the identification information is invalid, that is, it indicates that the current situation may be that the chassis fails to operate normally, or the carriage fails to successfully switch the operation mode, then an abnormal situation needs to be fed back to the first control terminal.

[0109] If the first operation mode identification information and the second operation mode identification information are the same, that is, it indicates that the wrong memory address is configured for the first mode switch on the chassis and the second mode switch in the carriage, then an abnormal situation needs to be fed back to the first control terminal.

[0110] When it is determined in the embodiment of the present invention that the first operation mode identification information is different from the second operation mode identification information, it is decided to use the second operation mode identification information to determine the current operation mode of the target carriage. When the current operation mode is the target operation mode after mode switching, it is decided to generate a corresponding control instruction through the carriage operation information to control the target component module to adjust the operation condition of the carriage environment to be adapted to the target operation mode. It can automatically switch the control logic in different operation scenarios, monitor the response degree of the chassis and the carriage to the operation mode switching, ensure the execution of correct cooperative control, improve the train operation flexibility and adaptability, and at the same time ensure the control accuracy, and avoid wasting the train operation cost.

[0111] Based on any of the above embodiments, generating a control instruction based on the carriage operation information includes: using the carriage operation information to perform a target service logic operation to obtain a control quantity of the target component module.

[0112] Wherein, the target service logic operation corresponds to the target operation mode.

[0113] Specifically, in step 103, the switching control device based on the detachable chassis and carriage set in the first control terminal substitutes the carriage operation information into the target service logic operation corresponding to the target operation mode to obtain the control quantities of the components in the target component module.

[0114] Package the control quantity of the target component module into the control instruction.

[0115] Specifically, the switching control device based on the detachable chassis and carriage set in the first control terminal packages the control quantities of the components in the target component module under the fields of the corresponding components to form a control instruction.

[0116] The embodiment of the present invention does not make specific limitations on the formation process of the control instruction.

[0117] Exemplarily, taking the switching between the passenger transport mode and the freight transport mode of the carriage and the coordinated control of the change of the lighting environment in the carriage as an example:

[0118] When the vehicle is running, all variable values are updated periodically. The variable Chassis_Num is the first operation mode identification information of the chassis, and the gear 0 in the first mode switch is pre-assigned as its memory address so that Chassis_Num is 0. The variable Carriage_Num is the second operation mode identification information of the carriage, and is set according to the two switchable operation modes:

[0119] If the switched operation mode is the freight mode, the gear 1 in the second mode switch is pre-assigned as the memory address for it, and Carriage_Num is set to 1, then the program corresponding to the freight mode is activated, and the business logic operation corresponding to the freight mode is executed. An AND operation is performed on the parking brake variable (boolean type) and the door open variable (boolean type) in the carriage operation information to obtain the control signal (boolean type) corresponding to the main lighting of the freight vehicle.

[0120] The component module corresponding to the lighting system will respond to the control signal corresponding to the main lighting of the freight vehicle and activate the lighting scheme corresponding to the freight carriage for lighting only when the train is in the parking brake and the doors are open.

[0121] If the switched operation mode is the passenger mode, the gear 2 in the second mode switch is pre-assigned as the memory address for it, and Carriage_Num is set to 2, then the program corresponding to the passenger mode is activated, and the business logic operation corresponding to the passenger mode is executed. An OR operation is performed on the inverted emergency lighting variable (boolean type) and the fire alarm variable (boolean type) in the carriage operation information, and then an AND operation is performed with the train operation variable (boolean type) to obtain the control signal (boolean type) corresponding to the main lighting of the passenger vehicle.

[0122] The component module corresponding to the lighting system will respond to the control signal corresponding to the main lighting of the passenger vehicle and activate the lighting scheme corresponding to the passenger carriage for lighting when the train is in the running state and neither the emergency lighting nor the fire alarm is triggered.

[0123] After activating the control program corresponding to the target operation mode in the embodiment of the present invention, the carriage operation information is substituted into the target business logic operation, and the control quantity of the target component module obtained is encapsulated into a control instruction to control the target component module to adjust the running condition of the carriage environment to be adapted to the target operation mode.

On the basis of any of the above embodiments, as Figure 5 shown, the system includes a first control terminal 510 arranged in each carriage, and a second control terminal 520 arranged on the chassis mechanically connected to the carriage. The first control terminal 510 is used to execute the switching control method based on the detachable chassis and carriage as described above. The second control terminal 520 is used to execute the switching control method based on the detachable chassis and carriage as described above.

[0199] The first control terminal 510 and the second control terminal 520 are communicatively connected.

[0200] The first control terminal 510 includes a first controller 511 and a second mode switch 512. The second control terminal 520 includes a second controller 521 and a first mode switch 522.

[0201] The second mode switch 512 is used to indicate the operation mode corresponding to the carriage according to the current position of the first mechanical pointer.

[0202] The first controller 511 is used to determine the second operation mode identification information according to the current position of the first mechanical pointer.

[0203] The first mode switch 521 is used to indicate the operation mode corresponding to the chassis according to the current position of the second mechanical pointer.

[0204] The second controller 522 is used to determine the first operation mode identification information according to the current position of the second mechanical pointer.

[0205] Wherein, the first mechanical pointer is arranged on the second mode switch. The second mechanical pointer is arranged on the first mode switch.

[0206] Specifically, before the train runs, set the mechanical pointer of the second mode switch 512 at the position corresponding to the target operation mode, and set the mechanical pointer of the first mode switch 522 at a position different from the indicated position of the second mode switch 512 to complete the mode switch. However, the internal environment of the carriage still operates in a manner corresponding to the original passenger transport mode.

[0207] During the train operation, when the first controller 511 in the first control terminal 510 identifies the pointer position of the second mode switch 512 to obtain the second operation mode identification information, it also receives the first operation mode identification information obtained by the second controller 521 in the second control terminal 520 identifying the pointer position of the first mode switch 522. Finally, after the first controller 511 confirms the current operation mode according to the first operation mode identification information and the second operation mode identification information, if the current operation mode is consistent with the target operation mode, then collect the carriage operation information of the target component module in the target carriage under the operation environment corresponding to the original operation mode, generate a control instruction, and adjust the operation condition of the target component module in the target carriage to be adapted to the current freight transport mode through the control instruction.

[0208] The embodiments of the present invention do not specifically limit the specific implementation manners of the switching control system based on the detachable chassis and carriage.

As Figure 6 shown, take the composition architecture of the train carriage 610, chassis 620, on-vehicle electrical cabinet 630, the first Logic Control Unit (LCU) as the first control terminal 640, off-vehicle electrical cabinet 650, and the second Logic Control Unit (LCU) as the second control terminal 660 as an example:

[0210] The LCU component is mainly composed of a power supply board, a main control board, a communication board, an IO board, a wiring board, and a backplane. Among them:

[0211] The power supply board is used to connect to the vehicle power supply, convert it into an appropriate voltage, and then supply power to other boards through the backplane.

[0212] The main control board is the main control unit and is responsible for logical processing.

[0213] The communication board is responsible for communicating with the vehicle and other LCUs.

[0214] The IO board is used to monitor the status of IO points.

[0215] The wiring board is used to connect the input and output signal hard wires.

[0216] The backplane is responsible for communication and power delivery between boards. Since the backplane cannot be directly observed at the rear of the chassis, it is not shown in the figure.

[0217] The rotary DIP switch set in the communication board of the second control terminal 660 is enlarged and shown in the figure as the first mode switch 670. If its mechanical pointer is placed at the "0" position, it indicates that the second control terminal 660 is operating normally. After the train car body 610 and the chassis 620 are reorganized and communicate, according to the "0" position where the mechanical pointer is placed, the first operation mode identification information is assigned the value of 0 to indicate the successful reorganization of the train car body 610 and the chassis 620.

If its mechanical pointer is placed at the "1" position, the freight mode can be assigned to it. After the train car body 610 and the chassis 620 are reorganized and communicate, according to the "1" position where the mechanical pointer is placed, the second operation mode identification information is assigned the value of 1 to indicate the activation of the program corresponding to the freight mode.

[0219] The rotary DIP switch set in the communication board of the second control terminal 660 is enlarged and shown in the figure as the second mode switch 680. If its mechanical pointer is placed at the "2" position, the passenger mode can be assigned to it. After the train car body 610 and the chassis 620 are reorganized and communicate, according to the "2" position where the mechanical pointer is placed, the second operation mode identification information is assigned the value of 2 to indicate the activation of the program corresponding to the passenger mode.

[0220] The CANs of the two LCUs are connected through the electrical plug connector 690 to achieve data sharing between the LCUs.

[0221] Among them, when the actual vehicle is running, the LCU writes data into the corresponding memory address according to the position of the rotary DIP switch. Therefore, the rotary DIP switches of the first mode switch 670 and the second mode switch 680 cannot be placed in the same position.

It can automatically switch the control logic in different operation scenarios, make adaptive modifications to the car body operation environment through personalized and differentiated collaborative control for different car bodies, improve the train operation flexibility and adaptability, and reduce the train operation cost.
