Example four

Based on the conference car 102 provided in the above embodiment, the present application also provides a rail vehicle 1, where the rail vehicle 1 includes the conference car 102, and as the rail vehicle 1 employs the conference car 102 in the above embodiment, please refer to the above embodiment for the beneficial effects of the rail vehicle 1.

With the technological and social progress, rail transit users will put higher demands on mobile conferences. For example, in a large important meeting, there are many participants, and the participants who need to ride on different rail vehicles need to start the meeting or need to start the meeting temporarily, and at this time, the rail vehicles need to establish communication and operate in a flexible grouping mode, so as to ensure the operating distance and synchronism among the vehicles. The participants can enter the conference carriage in the rail vehicle to start the conference synchronously. At the moment, each rail vehicle adopts the following flexible marshalling operation control method to flexibly marshalling and operating.

As shown in fig. 15, a flexible grouping operation control method flow for the rail vehicle provided in this embodiment is applied to the first train.

The first train is any group of independently marshalled or independently marshalled rail vehicles, which includes the conference cars 102 in the foregoing embodiment, and the train establishes a flexible marshalling with other trains (such as the second train, which is any other rail vehicle that is independently marshalled or independently marshalled and operates, and which may also include the conference cars 102 in the foregoing embodiment) by using the method provided in this embodiment, and performs interval control on the flexible marshalling.

The first train is a group of rail vehicles that have been independently marshalled or operated independently, and the "first" in the first train is used for identification purposes only and has no other meaning in order to distinguish other trains. Similarly, the second train is also a group of rail vehicles that have been independently marshalled or operated independently, and the "second" in the second train is used for identification purposes only and has no other meaning in order to distinguish other trains. Of course, the second train may be a rail vehicle having the same configuration and arrangement as the first train.

The flexible grouping operation control method is realized by the following steps:

101, obtaining a train information list sent by a data interaction center.

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

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

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

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

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

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

And 103, establishing a flexible marshalling with the second train according to the train information list and the distance between the second train and the flexible marshalling.

In particular, the method comprises the following steps of,

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

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

The second train is any train group except the first train, and the flexible grouping establishment of the train is also to be carried out. The second train is two different sets of trains from the first train, and the first train and the second train establish a flexible consist through step 103.

The critical communication distance is the distance between two trains without collision accidents under any condition, the front train is in a static state, and the distance between the two trains calculated under the condition is the farthest distance which is the product of the maximum service braking distance and a preset value.

Taking the preset value as 1.5 as an example, the critical communication distance is the maximum service braking distance 1.5.

103-3, receiving a second topological frame sent by a second train based on the communication.

The second topological frame is only used for identification, and does not have any other meaning in order to distinguish the topological frames sent by other trains. That is, the second topology frame is a topology frame, and is a topology frame transmitted by the second train, that is, a topology frame of the second train.

In addition, the topology frame includes an initial operation flag, an IP address list, an initial operation completion flag, and the like.

The initial operation mark is used for describing whether the train is forbidden to form a train or not.

The initial operation completion mark is used for describing whether the train completes initial 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 information frame is only used for identification, 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 flexible grouping according to the second topological frame.

In particular, the method comprises the following steps of,

1. determining an operating curve

If it is determined from the second topological frame that the grouping condition is not satisfied, then

1.1 when the first train is in front of the second train, determining automatic driving.

1.2 when the first train is behind the second train, determining the flexible marshalling operation curve according to the operation information of the second train.

Because the topology frame includes the initial operation flag, which is used to describe whether the train to which the topology frame belongs is forbidden to form a train, the specific judgment method for determining that the train does not meet the formation condition according to the second topology frame is as follows:

and if the initial operation flag of the second topology frame is forbidden (such as the second train refuses to form the group), determining that the group condition is not met.

Or,

if the initial operation flag of the first topology frame of the first train is disabled (e.g., the first train rejects the consist), it is determined that the consist condition is not satisfied.

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

Or,

and if the initial operation mark of the first topological frame is not forbidden and the initial operation mark of the second topological frame is not forbidden but the first train and the second train meet the forbidden marshalling condition, determining that the marshalling condition is not met.

The first train and the second train meet the forbidden marshalling condition as follows:

the lead curve in the first and second trains decelerates. Or,

and the front train in the first train and the second train enters the speed-limiting section. Or,

the first train and the second train cannot run the consist simultaneously for the set time.

For example, the time specified for the grouping is 10 minutes. That is, a premise for establishing a flexible consist for two trains is that the vehicles can be operated in the consist for 10 minutes.

If the train (i.e. the first train) rejects the marshalling (the initial operation mark in the topological frame is forbidden) or the adjacent train (i.e. the second train) rejects the marshalling (the initial operation mark in the topological frame is forbidden) or the two trains do not have marshalling conditions (the curve of the front train is decelerated, the front train enters the speed-limited road section and can not simultaneously operate the marshalling for a specified time), the front train keeps automatically operating (i.e. 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 the flexible marshalling operation curve according to the operation information of the front train (i.e. when the first train is positioned behind the second train, the first train is the waiting train, and the flexible marshalling operation curve is determined according to the operation information of the second train at the moment).

If it is determined from the second topological frame that the grouping condition is satisfied, then

2.1 determining an operating curve for the flexible consist from the operating data of the second train when the first train is 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 determining the operation curve of the flexible consist from the operation data of the second train, it is also confirmed whether the communication is stable, and if so, the flexible consist setup is considered to be completed.

The mode for determining the communication stability is as follows: the messages received continuously in n communication cycles do not lose packets, where n is a preset positive integer, for example, n is 10, that is, the messages in 10 communication cycles do not lose packets.

Since the second topology frame sent by the second train is received based on the communication in step 103-3, the packets continuously received in the n communication periods do not lose packets, that is, the packets continuously received in the n communication periods do not lose packets. If the second topology frame sent by the second train is received and the second topology frame sent by the second train is also received based on the communication in step 103-3, then the packets continuously received in n communication cycles do not lose packets, that is, the packets continuously received in n communication cycles do not lose packets, or the packets continuously received in n communication cycles do not lose packets.

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

The first information frame is only used for identification, 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 relation between the step of the first train sending the first topological frame and the first information frame to the second train and the step 103-3 may be various, for example, the first train sends the first topological frame and the first information frame to the second train first, and then the step 103-3 is executed. For another example, the first train first performs step 103-3, and then sends the first topology frame and the first information frame to the second train. Also for example, the first train simultaneously both sends the first topology frame and the first information frame to the second train and performs step 103-3.

Since there are two sets of adjacent trains (i.e., the first train's front train and the next train) for one train, the second train is one set of adjacent trains for the first train, and the first train has another set of adjacent trains, the other set of adjacent trains is named as the third train for the purpose of clearly distinguishing the two sets of different adjacent trains. That is, the third train is an adjacent train of the first train, and the third train is different from the second train.

The third train is just for identification, and does not have any other meaning for distinguishing other trains. That is, the third train is a set of trains that is another set of neighbors of the first train than the second train.

During the process of sending the first topological frame and receiving the second topological frame, the first train also receives a third topological frame sent by a third train.

Wherein the third topology frame. The third one in (1) is just for identification, and does not have any other meaning in order to distinguish topological frames of other trains. That is, the third topological frame is a topological frame that is transmitted by the third train, i.e., the third train.

If the third topological frame does not include the first IP address of the first train, the third topological frame is divided into a first topological frame and a second topological frame

1. And updating the 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 following steps of,

if the third train is located in front of the first train (i.e. the third train is a front train of the first train), then

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

2) And 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 train of the first train), then

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

2) And forming an updated first IP address list before the second IP address list is put into the first IP address in the 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 simultaneously calculate new topology frames in the process of mutually sending topology frames, if the topology frame received by the front train (such as the third train) does not contain the IP address of the self-vehicle (i.e. the first train), the topology frame IP address list of the rear train (i.e. the second train) is placed behind the IP address of the self-vehicle (i.e. the first train) to form a new IP address list to form a topology frame, if the topology frame received by the rear train (such as the third train) does not contain the IP address of the self-vehicle (i.e. the first train), the IP address list of the front train (i.e. the second train) is placed in front of the IP address of the self-vehicle (i.e. the first train) to form a new IP address list to form a topology frame, if the topology frame received by the train is consistent with the topology frame of the self-train, the initial operation is judged to be successful, the new topology frame is sent after the initial operation completion mark is set, when the initial operation completion marks of all the received and sent topology frames are consistent, it is determined that the flexible consist is established to be complete and the consist complete flag is set, and the train reference direction is set.

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

For example,

if the first train is located in front of the second train (i.e. the first train is the front train), then

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

And receiving a control right acquisition request sent by the second train.

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 front train, when the first train determines that the formation completion flag is 1, the control command is sent to the rear train (i.e., the second train) to request to acquire the control right, and when the rear train (i.e., the second train) determines that the formation completion flag is 1 and receives the control command of the front train (i.e., the first train), the control right transfer response is sent to the front train (i.e., the first train); the front train (namely the first train) sends a specific control command to the rear train (namely the second train) after receiving the response frame of the rear train (namely the second train), and the rear train (namely the second train) executes the control command of the front train (namely the first train) after receiving the control command and does not automatically drive any more.

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

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

And 104, performing interval control on the flexible grouping.

After step 103 has been performed, a flexible consist has been established between the first train and the second train, which is controlled in step 104. During control, the interval control of the front vehicle on the flexible grouping is embodied as follows: the front vehicle determines 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 flexible marshalling by the rear vehicle is embodied in that: the traction/braking force information of the vehicle itself is transmitted to the preceding vehicle, and the traction/braking force determined by the preceding vehicle is executed. If the first train is positioned in front of the second train, the first train is a front train, and if the first train is positioned behind the second train, the first train is a rear train.

In the following, how the first train performs interval control on the flexible grouping is described with respect to two situations, namely, the situation where the first train is located in front of the second train and the situation where the first train is located behind the second train.

In the first case: the first train is positioned in front of the second train, and the first train is a front train and the second train is a rear train at the moment. The first train needs to determine the traction/braking force at each moment according to the traction/braking force information of the following train and transmit the determined traction/braking force to the following train. The second train needs to transmit its own traction/braking force information to the first train and perform the traction/braking force determined by the first train.

In particular, the first train party

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

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

If the current operating phase is not the shutdown phase, then

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

If the current operating phase is a parking phase, then

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

And when the distance between the train and the second train is smaller than the parking interval, calculating the braking distance according to the current speed after the braking condition is determined to be met. And when the ground position information is acquired, calculating the current braking rate based on the braking distance and the acquired ground position information, carrying out deceleration braking according to the current braking force, calculating the traction/braking force at the next moment, and carrying out interval control according to the traction/braking force at the next moment.

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

Wherein, according to the traction/braking force information, the process of calculating the traction/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 second train and the current speed.

and a.2, determining the minimum distance of the interval control.

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

S_min＝T_sum*V_back+ΔS+d。

wherein,

S_minthe minimum distance is controlled for the separation.

T_sumFor time delay, T_sum＝t_c+t_p+t_b，t_cFor communication interruption time, t_pFor algorithm execution time, t_bIs the brake command issue to brake application time.

V_backIs the second train operating speed.

And delta S is the difference between the emergency braking distances of the first train and the second train.

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

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

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

the tractive effort/braking effort at the next moment is sent to the flexible consist control unit of the second train by the flexible consist control unit. So that the second train forwards the traction/braking force at the next moment to a CCU (Central Control Unit) of the second train through the flexible consist Control Unit, and applies the traction/braking force at the next moment through the CCU of the second train so as to Control the speed of the second train.

In the second case: the first train is located behind the second train, and at the moment, the second train is a front train and the first train is a 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 train and send the determined traction/braking force to the rear train. The first train needs to send its own tractive effort/braking effort information to the second train and perform the tractive effort/braking effort determined by the second train.

Specifically, the first train sends traction/braking force information to the second train, so that the second train calculates the 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 next time tractive effort/braking effort sent by the second train is also received by the flexible consist control unit. The tractive effort/braking effort at the next moment is forwarded to the CCU of the second train by the flexible consist control unit. The next moment 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 the step 104, the marshalling of the train in the marshalling as a whole can be controlled by the marshalling operation of the head train on the basis of wireless marshalling and automatic operation among a plurality of trains. The method mainly comprises the steps of calculating an interval control curve after the train is marshalled, and controlling the train to keep a running interval in the flexible marshalling advancing process.

For example, the front train controls the advancing speed of the train in the marshalling according to real-time state signals of the position, the real-time speed, the braking distance, the working condition of a braking system and the like of the train and the braking distance of the train, so that the running distance of the flexibly marshalled train is kept, the train can be safely braked under special working conditions, and rear-end collision is avoided.
