[0047] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] Figure 1 FIG. 1 is a flow chart of a method for controlling the operation of a train with detachable carriages and chassis provided by the present invention. Figure 1 As shown, the method includes:

[0049] Step 100: When it is determined that the locking device between the carriage and the chassis of the train is separated, determine the device action sequence in the process of separating or combining the carriage and the chassis according to the received control command;

[0050] Step 200: Control the separation or combination of the carriage and the chassis according to the equipment action sequence.

[0051] It should be noted that the execution subject of the above method may be a computer device.

[0052] Optionally, the method for controlling the operation of a train with detachable carriages and chassis provided by the present invention may be applicable to: Figure 2 and Figure 3 The train with detachable carriages and chassis shown. By modularizing the chassis, the carriages can be customized, such as passenger carriages and freight carriages, to be compatible with multiple operating modes. Passenger carriages are used during peak hours, and some vehicles can be replaced with freight carriages during non-peak hours, which means that passenger capacity is maintained while the line is used for freight functions to increase revenue.

[0053] The train includes a carriage, a chassis detachable from the carriage, and an automatic train driving system (not shown in the figure) located in the carriage, wherein the carriage and the chassis are connected by an electrical plug, a locking device, and a telescopic device.

[0054] In one embodiment, the electrical plug and the locking device are respectively disposed on the vehicle body and the chassis.

[0055] In one embodiment, the telescopic device may specifically be a telescopic device made of a front-end glass fiber reinforced plastic (GRP) material (hereinafter referred to as a GRP telescopic device).

[0056] See also Figure 2 When the car body is combined with the chassis, the electrical plugs and locking devices on the car body and the chassis are connected together, and the telescopic device is retracted at the same time.

[0057] When the car body is separated from the chassis, the electrical plugs and all locking devices on the car body and chassis are disconnected (the normally open contacts of the locking devices are disconnected, and the normally closed contacts of the locking devices are closed), and the GRP telescopic device is extended at the same time. Figure 3 shown.

[0058] In one embodiment, the status of the carriage and chassis is collected through the safety input of the train signal system to determine whether the train is operating safely; through the safety input and output of the train safety network, combined with the train hard-wired circuit, the equipment action timing during the separation / combination of the carriage and chassis is controlled and the status is detected to ensure that the separation / combination process of the carriage and chassis is safe and reliable.

[0059] In one embodiment, the carriage and chassis are combined through four locking devices. To ensure driving safety, it is necessary to ensure that the status of the locking devices is monitored in real time during driving, and if separation occurs, the emergency brake or parking brake is immediately applied. Each locking device has a normally open contact and a normally closed contact. The train signal safety acquisition system collects the status of each normally open contact and each normally closed contact, meeting the requirements of the safety integrity input level (SIL4 level). If any locking device is separated during the train driving (i.e., the normally open contact of the locking device is disconnected, and the normally closed contact of the locking device is closed), it is considered that the carriage and chassis need to be separated or combined, and the emergency brake or parking brake should be applied immediately.

[0060] When it is determined that the locking device between the carriage and the chassis of the train is separated, the equipment action timing during the separation or combination of the carriage and the chassis is determined according to the control command received.

[0061] In one embodiment, step 100 may specifically include:

[0062] Step 1001: If the received control command is a separation command, determine the device action sequence according to the preset car body and chassis separation action sequence;

[0063] Step 1002: If the received control command is a combination command, determine the equipment action sequence according to the preset car body and chassis combination action sequence.

[0064] Optionally, when the control instruction received by the train is a separation command (used to instruct the separation of the car and chassis), the equipment action timing during the separation of the car and chassis is determined according to the preset car and chassis separation action timing, and the safe separation of the car and chassis is controlled according to the equipment action timing.

[0065] When the control instruction received by the train is a combination command (used to instruct the combination of the carriage and the chassis), the equipment action timing in the process of combining the carriage and the chassis is determined according to the preset carriage and chassis combination action timing, and the safe combination of the carriage and the chassis is controlled according to the equipment action timing.

[0066] The method for controlling the operation of a train with detachable carriages and chassis provided by the present invention can solve the problems of safe train operation and safe separation / combination of carriages and chassis in a mode in which carriages and chassis are detachable / combinable. The separation / combination of carriages and chassis is controlled according to the equipment action sequence during the separation / combination process of carriages and chassis. By sharing the chassis, the chassis can be used for both passenger and cargo transportation, thereby effectively avoiding waste of resources.

[0067] Furthermore, in one embodiment, step 200 may specifically include:

[0068] Step 2000: When it is determined that the train has applied parking brake or emergency brake, control the carriage to be powered off;

[0069] Step 2001: When it is determined that the power-off duration of the carriage reaches a first preset threshold, control the telescopic device to extend;

[0070] Step 2002: when it is determined that the extension time of the telescopic device reaches a second preset threshold, if it is determined that the telescopic device is fully extended, the electrical plug is controlled to be separated;

[0071] Step 2003: when it is determined that the duration of the electrical plug separation action reaches a third preset threshold, if it is determined that the electrical plug is completely separated, controlling the locking device to separate;

[0072] Step 2004: when it is determined that the duration of the locking device separation action reaches a fourth preset threshold, if it is determined that the locking device is completely separated, the carriage is raised by controlling the carriage lifting machine;

[0073] Step 2005: When it is determined that the duration of the car body lifting action reaches a fifth preset threshold, the telescopic device is controlled to retract again to complete the separation of the car body from the chassis.

[0074] Wherein, the carriage and the chassis are connected via the telescopic device, the electrical plug and a plurality of locking devices.

[0075] Optionally, when it is determined that the train has applied parking brakes or emergency brakes, it can be confirmed that the locking device is disengaged and the locking device can be disconnected. Figure 4 The carriage and chassis separation action sequence shown is used as the equipment action sequence during the carriage and chassis separation process to control the safe separation of the carriage and chassis.

[0076] After receiving the separation command, if the train has applied the parking brake or emergency brake and confirmed (the train speed is 0km / h at this time), ensure that the train cannot move during the separation process.

[0077] At this point, the train safety network requires the carriage to be powered off.

[0078] In one embodiment, the power supply contactor is controlled to be disconnected to cut off the power supply to the carriage (to prevent arcing and short circuit and ensure the safety of the carriage equipment).

[0079] When the power outage duration of the car reaches a first preset threshold, the GRP telescopic device at the front end is extended through the train safety network to prevent damage to the GRP telescopic device during the separation of the car and the chassis, and the extension duration of the GRP telescopic device is within a second preset threshold.

[0080] It should be noted that the first preset threshold value may be set according to actual scenarios, and the present invention does not specifically limit this. For example, in one embodiment, the first preset threshold value may specifically be 2s.

[0081] If it is determined that the extension duration of the GRP telescopic device is within the second preset threshold and the GRP telescopic device is fully extended (i.e., the extension of the GRP telescopic device is completed), the electrical plug is controlled to start separation (to prevent damage to the electrical plug during the separation of the car body and the chassis), and the separation duration of the electrical plug is the third preset threshold.

[0082] It should be noted that the second preset threshold can be set according to the actual scenario, and the present invention does not make any specific limitation to this. For example, in one embodiment, the second preset threshold can be specifically 5s.

[0083] When it is determined that the duration of the electrical plug separation action reaches the third preset threshold, if the electrical plug is judged to be completely separated (that is, the electrical plug separation action is completed), the locking device is controlled to start separation (at this time, the car body and the chassis begin to separate), and the duration of the locking device separation action is the fourth preset threshold.

[0084] It should be noted that the third preset threshold value may be set according to actual scenarios, and the present invention does not specifically limit this. For example, in one embodiment, the third preset threshold value may specifically be 10s.

[0085] When it is determined that the duration of the locking device separation action reaches the fourth preset threshold, if the locking device is judged to be completely separated (that is, the locking device separation action is completed), the car body is raised by controlling the car lifting machine, and the car lifting machine starts the car body lifting action, and the duration of the car body lifting action is the fifth preset threshold.

[0086] In one embodiment, whether the locking device is completely and reliably disengaged can be determined through the train safety network.

[0087] It should be noted that the fourth preset threshold can be set according to actual scenarios, and the present invention does not make any specific limitation to this. For example, in one embodiment, the fourth preset threshold can be specifically 10s.

[0088] When it is determined that the duration of the car body lifting action reaches the fifth preset threshold, it is determined that the car lifting machine action is completed, and the GRP telescopic device is controlled to retract again. At this point, the separation process of the car body and the chassis is completed.

[0089] It should be noted that the fifth preset threshold can be set according to actual scenarios, and the present invention does not make any specific limitation to this. For example, in one embodiment, the first preset threshold can be specifically 90s.

[0090] The present invention provides a method for controlling the operation of a train with detachable carriages and chassis, which realizes reliable separation of the carriages and chassis of a rail vehicle through the equipment action sequence during the separation process of the carriages and chassis, thereby ensuring driving safety and the safety of structural components during the separation process.

[0091] Furthermore, in one embodiment, step 200 may further specifically include:

[0092] Step 2006: If it is determined that the parking brake or emergency brake has been applied to the train, control the train to stop;

[0093] Step 2007: When it is determined that the train stop time reaches a sixth preset threshold, controlling the telescopic device to extend;

[0094] Step 2008: When it is determined that the time duration of the extension of the telescopic device reaches a seventh preset threshold, the carriage is controlled to fall by the carriage lifting machine;

[0095] Step 2009: when it is determined that the duration of the carriage falling action reaches an eighth preset threshold, if it is determined that the carriage has completely fallen, the locking device is controlled to lock;

[0096] Step 20010: When it is determined that the locking action duration of the locking device reaches a ninth preset threshold, the electrical plug is controlled to retract;

[0097] Step 20011: When it is determined that the retraction time of the electrical plug reaches the tenth preset value, the telescopic device is controlled to retract to complete the combination of the car body and the chassis.

[0098] Optionally, when it is determined that the train has applied parking brakes or emergency brakes, it can be confirmed that the locking device is disengaged and the locking device can be disconnected. Figure 5 The car body and chassis separation action sequence shown is used as the equipment action sequence during the car body and chassis combination process to control the safe combination of the car body and chassis.

[0099] After receiving the coupling command, if the train has applied the parking brake or emergency brake and confirmed (the train speed is 0km / h at this time), ensure that the train cannot move during the coupling process.

[0100] When it is determined that the train stop time reaches the sixth preset threshold, the GRP telescopic device at the front end is extended through the train safety network (to prevent damage to the GRP telescopic device during the combination of the car and the chassis), and the extension time of the GRP telescopic device is within the seventh preset threshold.

[0101] It should be noted that the sixth preset threshold can be set according to actual scenarios, and the present invention does not specifically limit this. For example, in one embodiment, the sixth preset threshold can be specifically 2s.

[0102] If it is determined that the extension duration of the GRP telescopic device is within the seventh preset threshold, the GRP telescopic device is fully extended (i.e., the extension action of the GRP telescopic device is completed), the car body is controlled to fall through the car lifting machine, and the car lifting machine starts to initiate the car body falling action, and the car body falling action duration is the eighth preset threshold.

[0103] It should be noted that the seventh preset threshold can be set according to actual scenarios, and the present invention does not make any specific limitation to this. For example, in one embodiment, the seventh preset threshold can be specifically 5s.

[0104] When it is determined that the duration of the car body falling action reaches the eighth preset threshold, the car lifting machine action is determined to be completed. After the car lifting machine action is completed, the locking device starts to lock the car body and chassis structure to ensure complete and reliable contact. The locking action duration of the locking device is the ninth preset threshold.

[0105] It should be noted that the eighth preset threshold can be set according to actual scenarios, and the present invention does not specifically limit this. For example, in one embodiment, the eighth preset threshold can be specifically 90s.

[0106] After the train safety network detects that the locking action of the locking device is completed (that is, the locking action duration of the locking device reaches the ninth preset threshold), the electrical plug on the chassis begins to retract and connects to the carriage end. The retraction time of the electrical plug is the tenth preset threshold.

[0107] It should be noted that the ninth preset threshold can be set according to actual scenarios, and the present invention does not make any specific limitation to this. For example, in one embodiment, the ninth preset threshold can be specifically 10s.

[0108] When it is determined that the retraction time of the electrical plug reaches the tenth preset threshold, the retraction action of the electrical plug is completed, and the GRP telescopic device is controlled to retract. The retraction action of the GRP telescopic device can be set to 5s. When the GRP telescopic device is fully retracted, the combination process of the car body and the chassis is completed.

[0109] It should be noted that the tenth preset threshold value may be set according to actual scenarios, and the present invention does not specifically limit this. For example, in one embodiment, the tenth preset threshold value may specifically be 10s.

[0110] The present invention provides a method for controlling the operation of a train with a detachable carriage and chassis, which realizes reliable combination of the carriage and chassis of a rail vehicle through the equipment action sequence during the combination of the carriage and chassis, thereby ensuring driving safety and the safety of structural components during the combination process.

[0111] Furthermore, in one embodiment, before step 100, the method may further specifically include:

[0112] Whether the locking device is separated is determined based on the monitored states of the normally open contact and the normally closed contact in the locking device.

[0113] Furthermore, in one embodiment, the method may further specifically include:

[0114] If it is determined that the locking device is disengaged, determining whether the train is in a stationary state;

[0115] If so, parking brake or emergency brake is applied to the train;

[0116] If not, emergency braking is applied to the train.

[0117] Optionally, take the example of the carriage and chassis being combined through four locking devices. To ensure driving safety, it is necessary to ensure that the status of each locking device is monitored in real time during driving, and if separation occurs, the emergency brake or parking brake is applied immediately. Each locking device has a normally open contact and a normally closed contact. The train signal safety acquisition system collects the status of the normally open contact and the normally closed contact through the safety integrity level (SIL4). If any locking device is separated during the train driving, it is considered that the carriage and chassis need to be separated or combined, and the emergency brake or parking brake is applied immediately.

[0118] In one embodiment, when it is determined that the locking device is disengaged, if the train is determined to be in a stationary state (i.e., the train speed is zero), parking brakes or emergency brakes should be applied to the train; when the train is determined to be in a running state (the train speed is non-zero), emergency brakes should be applied to the train.

[0119] In one embodiment, the judgment logic of whether the locking device is in a disengaged state during the train running is as follows: Figure 6 As shown:

[0120] 1. The normally open contacts and normally closed contacts of all locking devices under the vehicle are connected to input points that meet the SIL4 requirements. According to the status of the normally open contacts and normally closed contacts of each locking device monitored by the input points, it is determined whether the locking device is separated.

[0121] It should be noted that the initial states of the normally open contacts and normally closed contacts of the locking device are: the normally open contacts are disconnected and the normally closed contacts are closed. To ensure the safe operation of the train, the normally open contacts of the locking device should be closed and the normally closed contacts should be disconnected. When during the operation of the train, if the train signal safety acquisition system detects that the normally open contacts of the locking device are disconnected and the normally closed contacts are closed, it means that the locking device is separated. At this time, the safety loop contacts connected to the train signal safety acquisition system are disconnected, and the emergency braking logic judgment is triggered to determine the locking device that has been separated. To ensure the safe operation of the train, the parking brake or emergency brake should be applied immediately. After the train stops, according to the received combination command, the normally open contacts of the separated locking device are closed and the normally closed contacts are disconnected according to the equipment action timing when the car and chassis are combined.

[0122] When the carriage needs to be replaced, after the train stops, according to the received separation command, the normally open contacts of the locking device are controlled to open and the normally closed contacts are controlled to close according to the equipment action sequence when the carriage is separated from the chassis.

[0123] 2. If the train is stationary or moving, such as when the train speed is greater than the preset minimum speed threshold (0.5 km / h) and separation occurs, the train applies emergency braking or parking braking.

[0124] At the same time, since the train positioning accuracy and the separation equipment (car lifting machine) accuracy cannot currently meet the requirements for car separation / combination, in order to avoid damage to the locking device, electrical plug, GRP telescopic device and the risk of electrical overvoltage, short circuit, etc. during the separation and combination process, the above-mentioned equipment action timing control is designed during the separation and combination process. Through the safety input and output control of the train safety network (in compliance with SIL2 level requirements), the safety of equipment action during the separation / combination of the chassis and the car can be fully guaranteed.

[0125] The method for controlling the operation of a train with detachable carriages and chassis provided by the present invention solves the problems of safe operation and safe separation / combination of trains in a mode in which the carriages and chassis are detachable / combinable, controls and detects the separation / combination of the carriages and chassis, and fully automates the process, thereby reducing human intervention, thereby improving safety and effectively reducing costs.

[0126] The following is a description of the train operation control system with detachable carriage and chassis provided by the present invention.
