Example IV

Based on the commercial car provided in the above embodiment, the present application further provides a rail vehicle 1, where the rail vehicle 1 includes any one of the commercial cars in the above embodiment, and since the rail vehicle 1 employs the commercial car in the above embodiment, the beneficial effects of the rail vehicle 1 are referred to the above embodiment.

With technological and social advances, rail transit users will put higher demands on mobile conferences. For example, in a large important meeting, a large number of meeting participants need to or temporarily need to start the meeting by the meeting participants who are riding on different rail vehicles, and at this time, each rail vehicle needs to establish communication and operate in a flexible grouping form so as to ensure the running distance and synchronism among the vehicles. The meeting participants can enter the meeting carriage in the railway vehicle to synchronously start the meeting. At this time, each railway vehicle is flexibly grouped and operated by adopting the following flexible grouping operation control method.

As shown in fig. 15, the present embodiment provides a flexible grouping operation control method flow of a rail vehicle, and the method is applied to a first train.

The first train is any group of railway vehicles which are independently grouped or independently grouped and run, the railway vehicles comprise commercial carriages in the embodiment, namely a conventional riding area 101 and a commercial conference area 102, the train establishes flexible grouping with other trains (such as a second train, which is any other railway vehicle which is independently grouped or independently grouped and run, and the railway vehicles can also comprise commercial carriages in the embodiment) and performs interval control on the flexible grouping.

The first train is a group of rail vehicles that have been individually grouped or operated individually, and the "first" in the first train is merely for identification purposes and does not have any other meaning in order to distinguish between other trains. Likewise, the second train is also a group of rail vehicles that have been independently grouped or operated independently grouped, and the "second" in the second train is merely for identification purposes and does not have any other meaning in order to distinguish between other trains. Of course, the second train may be a rail vehicle having the same structure and arrangement as the first train.

The flexible grouping operation control method is realized as follows:

and step 101, acquiring a train information list sent by the data interaction center.

Wherein the train information list is sent by the data interaction center.

Before executing step 101, each train (including the first train, where the first train is any group of trains in all trains) sends running information to the ground control center in real time, after receiving the running information sent by each train, the ground control center sends the running information to the data interaction center, and the data interaction center determines a train information list according to the running information and sends the train information list to the trains. For example, the data interaction center obtains location information. And identifying trains running in the same direction on the same track from the position information and the running information. And determining a train information list according to the identified train. And transmitting the train information list to the train.

And 102, monitoring the distance between the second train and the first train in real time.

Specifically, the distance between the first train and the second train is monitored in real time through the flexible marshalling control unit.

And when the distance between the flexible marshalling control unit and the second train is monitored to be smaller than the minimum distance, the real-time monitoring through the flexible marshalling control unit is changed into the real-time monitoring through the interval control unit.

Wherein the minimum distance is a preset value, such as 200 meters.

Step 103, establishing flexible grouping with the second train according to the train information list and the distance between the second train and the second train.

In particular, the method comprises the steps of,

and 103-1, analyzing the train information list to obtain the number of trains.

103-2, if the number of trains is greater than 1 and the distance between the second train and the second train meets the critical communication distance, communicating with the second train.

Wherein the second train is any group of trains other than the first train, which is also to be set up for flexible consist. The second train is two different sets of trains than the first train, and the first train and the second train establish a flexible consist, via step 103.

The critical communication distance is the distance that no collision accident occurs to two trains under any condition, the front train is set to be in a static state, and the calculated distance between the two trains is the product of the maximum service braking distance and a preset value.

Taking a preset value of 1.5 as an example, the critical communication distance=maximum service braking distance×1.5.

103-3, receiving a second topology frame transmitted by the second train based on the communication.

The "second" in the second topology frame is only used as a marking, and does not have any other meaning in order to distinguish the topology frames sent by other trains. That is, the second topology frame is a topology frame, which is a topology frame transmitted by the second train, i.e., a topology frame of the second train.

In addition, the topology frame includes a primary running flag, an IP address list, a primary running completion flag, and the like.

The primary running flag is used to describe whether the train to which it belongs is forbidden to be grouped.

The primary operation completion flag is used for describing whether the train is completed in primary operation.

In step 103-3, in addition to receiving the second topology frame transmitted by the second train based on the communication, a second information frame transmitted by the second train is also received simultaneously.

The "second" in the second information frame is only used as a flag, and does not have any other meaning in order to distinguish information frames sent by other trains. That is, the second information frame is a topology frame, and is an information frame transmitted by the second train, that is, an information frame of the second train.

103-4, establishing a flexible grouping according to the second topology frame.

In particular, the method comprises the steps of,

1. determining an operating curve

If it is determined from the second topology frame that the grouping condition is not satisfied

1.1 when a first train is located in front of a second train, autonomous driving is determined.

1.2 determining a flexible consist operating curve based on the operating information of the second train when the first train is located behind the second train.

Because the topology frame comprises the primary running mark, the primary running mark is used for describing whether the train is forbidden to be grouped, and therefore, the specific judging mode for determining that the grouping condition is not met according to the second topology frame is as follows:

If the first running flag of the second topology frame is disabled (i.e., the second train refuses to consist), then it is determined that the consist condition is not satisfied.

Or,

if the first topology frame of the first train is initially disabled (i.e., the first train refuses to consist), then it is determined that the consist condition is not satisfied.

The "first" in the first topology frame is only used as a marking, and does not have any other meaning in order to distinguish the topology frames sent by other trains. That is, the first topology frame is a topology frame, which is a topology frame of the first train.

Or,

if the initial running mark of the first topological frame is not forbidden and the initial running mark of the second topological frame is not forbidden, but the first train and the second train accord with the forbidden marshalling condition, the marshalling condition is determined not to be met.

The first train and the second train meet the forbidden grouping condition:

the front curves in the first train and the second train are decelerated. Or,

the lead train in the first train and the second train enters the speed limit section. Or,

the first train and the second train cannot operate the consist for a prescribed time at the same time.

For example, the predetermined time for the grouping is 10 minutes. That is, the precondition for two trains to establish a flexible consist is that the vehicles can run in consist for 10 minutes.

If the own train (namely, the first train) refuses to be grouped (the initial running mark in the topological frame is forbidden) or the adjacent train (namely, the second train) refuses to be grouped (the initial running mark in the topological frame is forbidden) or the two trains do not have the grouping condition (the front train is decelerated at a curve, enters a speed-limiting road section and cannot run for grouping for a set time simultaneously), the front train keeps automatic running (namely, when the first train is positioned in front of the second train, the first train is the front train, automatic driving is determined at the moment), and the rear train determines a running curve of the flexible grouping according to the running information of the front train (namely, when the first train is positioned behind the second train, the first train is a waiting train, and at the moment, the running curve of the flexible grouping is determined according to the running information of the second train).

If it is determined from the second topology frame that the grouping condition is satisfied

2.1 determining a flexible consist operating curve based on the second train operating data when the first train is located behind the second train.

Wherein the operational data includes, but is not limited to, one or more of the following: position, velocity, acceleration.

In addition, after the operation curve of the flexible consist is determined according to the operation data of the second train, whether the communication is stable or not is also confirmed, and if so, the establishment of the flexible consist is considered to be completed.

The manner of determining that the communication is stable is: the packets of n communication periods are continuously received without packet loss, where n is a preset positive integer, for example, n=10, i.e. the packets of 10 communication periods are continuously received without packet loss.

Since the second topology frame sent by the second train is received based on the communication in step 103-3, packets of n communication periods are continuously received without packet loss, i.e. packets of the second topology frame of n communication periods are continuously received without packet loss. If the second topology frame sent by the second train is received based on the communication in step 103-3, and the second topology frame sent by the second train is also received, packets of n communication periods are continuously received without packet loss, that is, packets of the second topology frame of n communication periods are continuously received without packet loss, or packets of the second information frame of n communication periods are continuously received without packet loss.

In addition, after communicating with the second train according to the train information list, the method further comprises: in addition, after step 103-2 is performed, the first topology frame and the first information frame are also transmitted to the second train.

The "first" in the first information frame is only used as a flag, and does not have any other meaning in order to distinguish information frames sent by other trains. That is, the first information frame is an information frame, and is an information frame of the first train.

The step of the first train sending the first topology frame and the first information frame to the second train may have various relationships with step 103-3, for example, the first train sends the first topology frame and the first information frame to the second train before performing step 103-3. For another example, the first train first performs step 103-3 and then transmits the first topology frame and the first information frame to the second train. Also for example, the first train simultaneously transmits both the first topology frame and the first information frame to the second train and performs step 103-3.

Since there are two adjacent trains (i.e., the preceding train and the following train of the first train) for one train, the second train is one adjacent train for the first train, and then the first train also has another adjacent train, which is named as the third train for the sake of clearly distinguishing between the two different adjacent trains. I.e. the third train is a neighbouring train of the first train and the third train is different from the second train.

The "third" in the third train is only a logo, and does not have any other meaning to distinguish other trains. That is, the third train is a group of trains that is another group of adjacent trains that is the first train in addition to the second train.

The first train also receives a third topology frame transmitted by a third train in the process of transmitting the first topology frame and receiving the second topology frame.

Wherein the third topology frame. The "third" in (a) is only a logo, and does not have any other meaning in order to distinguish topological frames of other trains. That is, the third topology frame is a topology frame that is transmitted by the third train, i.e., the topology frame of the third train.

If the third topology frame does not include the first IP address of the first train

1. And updating a first IP address list of the first train according to the position relation between the third train and the first train.

In particular, the method comprises the steps of,

if the third train is located before the first train (i.e., the third train is the lead of the first train), then

1) And acquiring a second IP address list in the second topological frame.

2) After the second IP address list is put into the first IP address in the first IP address list, an updated first IP address list is formed.

If the third train is located behind the first train (i.e., the third train is the rear of the first train), then

1) And acquiring a second IP address list in the second topological frame.

2) And before the second IP address list is put into the first IP address in the first IP address list, forming an updated first IP address list.

2. And forming a new first topology frame according to the updated first IP address list.

That is, the first train and the second train calculate new topology frames simultaneously in the process of mutually sending topology frames, if the topology frames received by the front train (such as the third train) do not contain the IP address of the own train (i.e. the first train), the topology frame IP address list of the rear train (i.e. the second train) is placed behind the own IP address (i.e. the first train) to form a new IP address list to form a topology frame, if the topology frames received by the rear train (such as the third train) do not contain the IP address of the own train (i.e. the first train), the IP address list of the front train (i.e. the second train) is placed in front of the own IP address (i.e. the first train) to form a new IP address list to form a topology frame, if the topology frames received by the trains are consistent with the topology frames of the own train, the first running is judged to be successful, the new topology frame is sent after the first running completion mark is set, the flexible grouping completion is determined when the first running completion mark of all the topology frames received and sent by all trains are consistent, and the train reference direction is set.

In addition, after the flexible grouping is established according to the second topology frame, the front vehicle can also acquire the control right of the rear vehicle.

For example, the number of the cells to be processed,

if the first train is located before the second train (i.e. the first train is the lead train)

And sending a control right acquisition request to the second train, wherein the control right acquisition request is used for indicating the second train to feed back a control right transfer response.

And after receiving the control right transfer response fed back by the second train, sending a control instruction to the second train, wherein the control instruction is used for indicating the second train to stop automatic driving.

If the first train is located behind the second train (i.e. the first train is a rear train), then

And receiving a second train sending control right acquisition request.

And feeding back a control right transfer response to the second train.

And receiving a control instruction sent by the second train.

And stopping automatic driving according to the control instruction.

For example, if the first train is the preceding train, the first train sends a control command to the following train (i.e. the second train) to request for obtaining control when the first train judges that the grouping completion flag is 1, and sends a control right transfer response to the preceding train (i.e. the first train) after the following train (i.e. the second train) judges that the grouping completion flag is 1 and receives the control command of the preceding train (i.e. the first train); the front vehicle (i.e. the first train) receives the response frame of the rear vehicle (i.e. the second train) and then sends a specific control command to the rear vehicle (i.e. the second train), and the rear vehicle (i.e. the second train) receives the rear-execution front vehicle (i.e. the first train) control command and does not drive automatically any more.

For another example, if the first train is a rear train, after receiving that the front train (i.e. the second train) requires to acquire the control right, sending a control right transfer response to the front train (i.e. the second train) after the broken grouping completion mark is 1; the front vehicle (i.e. the second train) receives the response frame of the rear vehicle (i.e. the first train) and then sends a specific control command to the rear vehicle (i.e. the first train), and the rear vehicle (i.e. the first train) receives the rear-execution front vehicle (i.e. the second train) control command and does not drive automatically any more.

It should be noted that, if the distance between the trains (e.g., the first train and the second train, the first train and the third train, etc.) is more than 200 meters, LTE-R or 5G may be used for communication, and if the distance is less than 200 meters, WIFI or radar may be used for communication.

Step 104, interval control is performed on the flexible grouping.

After step 103, a flexible consist has been established between the first train and the second train, and control is provided for the flexible consist at step 104. When in control, the front vehicle performs interval control on the flexible grouping, which is characterized in that: the front vehicle determines the traction/braking force at each moment according to the traction/braking force information of the rear vehicle and transmits the determined traction/braking force to the rear vehicle. The interval control of the rear truck on the flexible marshalling is realized in the following steps: the traction/braking force information of the front vehicle is sent to the front vehicle, and the traction/braking force determined by the front vehicle is executed. If the first train is located before the second train, the first train is a front train, and if the first train is located after the second train, the first train is a rear train.

How the first train performs interval control on the flexible consist is described below for the case that the first train is located before the second train and the case that the first train is located after the second train, respectively.

First case: the first train is located before the second train, and at this time, the first train is a front train and the second train is a rear train. The first train needs to determine the traction/braking force at each moment according to the traction/braking force information of the rear vehicle and send the determined traction/braking force to the rear vehicle. The second train needs to send its own traction/braking force information to the first train and perform the traction/braking force determined by the first train.

Specifically, the first train will

A.1 determines the current run phase of the flexible consist.

And A.2, performing interval control on the flexible grouping according to the current operation stage.

If the current operation phase is not a stop phase, then

And calculating the traction force/braking force at the next moment, and performing interval control according to the traction force/braking force at the next moment.

If the current operation phase is a stop phase, then

And when the distance between the train and the second train is not smaller than the parking interval, decelerating and parking based on the running curve of the single train, calculating the traction force/braking force at the next moment, and performing interval control according to the traction force/braking force at the next moment.

When the distance between the second train and the second train is smaller than the parking interval, after the braking condition is determined to be met, the braking distance is calculated according to the current speed. Every time the ground position information is acquired, the current braking rate is calculated based on the braking distance and the acquired ground position information, the deceleration braking is performed according to the current braking force, the traction force/braking force at the next moment is calculated, and the interval control is performed according to the traction force/braking force at the next moment.

No matter what the current running stage is, the traction/braking force at the next moment is calculated, and the calculation method is as follows: and acquiring traction/braking force information of the second train, and calculating traction/braking force at the next moment according to the traction/braking force information.

Wherein, according to the traction force/braking force information, the process of calculating the traction force/braking force at the next moment is as follows:

and a.1, calculating the speed deviation according to a pre-obtained speed-interval distance curve, the distance between the speed-interval distance curve and the second train and the current speed.

a.2 determining the gap control minimum distance.

Specifically, the interval control minimum distance is calculated by the following formula:

S _min ＝T _sum *V _back +ΔS+d。

wherein,

S _min to control the minimum distance.

T _sum For delay time, T _sum ＝t _c +t _p +t _b ，t _c For communication interruption time, t _p For algorithm execution time, t _b To the brake application time for a brake command.

V _back Is the second train operating speed.

Δs is the emergency braking distance difference between the first train and the second train.

d is a safety margin, e.g. d is 2 meters.

and a.3, calculating the traction force/braking force at the next moment according to the speed deviation, the train speed limit, the limited acceleration, the limited jerk value and the traction force/braking force information on the premise of meeting the minimum distance of interval control.

In addition, no matter what the current running stage is, the interval control is carried out according to the traction force/braking force at the next moment, and the control process is as follows:

the next time traction/braking force is transmitted to the flexible consist control unit of the second train by the flexible consist control unit. So that the second train forwards the next moment of traction/braking force to the CCU (Central Control Unit ) of the second train through the flexible consist control unit, and the next moment of traction/braking force is applied through the CCU of the second train in order to control the speed of the second train.

Second case: the first train is located behind the second train, at this time the second train is the front train, and the first train is the rear train. The second train needs to determine the traction/braking force at each moment according to the traction/braking force information of the rear vehicle and send the determined traction/braking force to the rear vehicle. The first train needs to send its own traction/braking force information to the second train and perform the traction/braking force determination by the second train.

Specifically, the first train sends traction/braking force information to the second train, so that the second train calculates traction/braking force at the next moment according to the traction/braking force information, and performs interval control according to the traction/braking force at the next moment.

In addition, the flexible marshalling control unit receives the traction force/braking force of the next moment sent by the second train. The next time traction/braking force is forwarded to the CCU of the second train by the flexible consist control unit. The next time traction/braking force is applied by the CCU to control the speed of the first train.

Through the process of interval control of the flexible marshalling in step 104, the marshalling operation control of the head car can be unified by taking the train in the marshalling as a whole on the basis of wireless marshalling and automatic operation among multiple trains. After the train is grouped, an interval control curve is calculated to control the train to keep the driving interval in the flexible grouping advancing process.

For example, the front train controls the running speed of the train in the marshalling according to real-time state signals such as the position of the train, the real-time speed, the braking distance, the working condition of the braking system and the like, combines the braking distance of the train, keeps the distance between the trains in the flexible marshalling, ensures that the train can be braked safely under the special working condition, and avoids rear-end collision.
