With the advancement of technology and society, rail transit users will put forward higher requirements for mobile conferences. For example, in a large-scale important meeting, there are many participants, and participants who need or temporarily need to ride on different rail vehicles to start the meeting. At this time, it is necessary for each rail vehicle to establish communication and operate in a flexible formation to ensure inter-vehicle communication. Running distance and synchronicity. Participants can enter the conference compartment in the rail vehicle to start the conference synchronously. At this time, each rail vehicle adopts the following flexible formation operation control method for flexible formation and operation.

As shown in FIG. 15 , the flow of a method for controlling flexible formation operation of rail vehicles provided by this embodiment is applied to the first train.

Wherein, the first train is any group of rail vehicles that have been formed independently or operated independently. The method provided establishes a flexible formation with other trains (such as the second train, any other rail vehicle that has been formed independently or operated independently, and the railway vehicle can also include the business car in the aforementioned embodiment) and the flexible formation is carried out at intervals control.

The first train is a group of rail vehicles that have been organized or operated independently. The "first" in the first train is only for identification purposes. In order to distinguish other trains, it does not have any other meaning. Similarly, the second train is also a group of rail vehicles that have been organized or run independently, and the "second" in the second train is only for identification purposes, and does not have any other meanings in order to distinguish other trains. Of course, the second train can also be a rail vehicle with the same structure and configuration as the first train.

The implementation process of the flexible marshalling operation control method is as follows:

Step 101, obtain the train information list sent by the data exchange center.

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

Before executing step 101, each train (including the first train, which is any group of trains in all trains) will send operation information to the ground control center in real time, and after the ground control center receives the operation information sent by each train , the operation information will be sent to the data interaction center, and the data interaction center will determine the train information list according to the operation information and send it to the train. For example, the data interaction center obtains location information. Identify the trains on the same track and in the same direction from the position information and running information. A train information list is determined according to the identified trains. Send train information list to train.

Step 102, monitor the distance to the second train in real time.

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

After monitoring and the distance between the second train is less than the minimum distance, the real-time monitoring by the flexible formation control unit will be changed to real-time monitoring by the interval control unit and the distance between the second train.

Wherein, the minimum distance is a preset value, for example, the minimum distance is 200 meters.

Step 103, according to the train information list and the distance to the second train, establish a flexible formation with the second train.

specific,

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

103-2. If the number of trains is greater than 1 and the distance to the second train satisfies the critical communication distance, communicate with the second train.

Wherein, the second train is any group of trains except the first train, and this train is also to be established in flexible formation. The second train and the first train are two groups of different trains, and the first train and the second train establish a flexible formation through step 103 .

Among them, the critical communication distance is the distance at which the two trains will not collide under any circumstances. Assuming that the vehicle in front is in a static state, the calculated distance between the two vehicles in this case is the farthest, which is the maximum common braking distance and the preset value product.

Taking the default value of 1.5 as an example, the critical communication distance = maximum normal braking distance * 1.5.

103-3. Based on the communication, receive the second topology frame sent by the second train.

Wherein, the "second" in the second topology frame is only used for identification, and does not have any other meaning in order to distinguish topology frames sent by other trains. That is to say, the second topology frame is a topology frame, which is a topology frame sent 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 run flag is used to describe whether the train to which it belongs is prohibited from forming.

The initial run completion flag is used to describe whether the train to which it belongs has completed the initial run.

In step 103-3, in addition to receiving the second topology frame sent by the second train based on communication, the second information frame sent by the second train will also be received at the same time.

Wherein, the "second" in the second information frame is only used for identification, and does not have any other meaning in order to distinguish the information frames sent by other trains. That is to say, the second information frame is a topology frame, which is an information frame sent by the second train, that is, an information frame of the second train.

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

specific,

1. Determine the operating curve

●If it is determined according to the second topology frame that the grouping condition is not met, then

1.1 When the first train is in front of the second train, determine automatic driving.

1.2 When the first train is behind the second train, determine the operating curve of the flexible formation according to the operating information of the second train.

Since the topology frame includes the initial operation flag, which is used to describe whether the train to which it belongs is forbidden to be marshalled, the specific judgment method for determining that the marshalling condition is not met according to the second topology frame is as follows:

If the initial running flag of the second topology frame is prohibited (for example, the second train refuses to be formed), it is determined that the formation condition is not met.

or,

If the initial running flag of the first topology frame of the first train is forbidden (for example, the first train refuses to be formed), it is determined that the formation condition is not met.

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

or,

If the initial running flag of the first topological frame is not forbidden, and the initial running flag of the second topological frame is not forbidden, but the first train and the second train meet the prohibition of marshalling, then it is determined that the marshalling condition is not met.

Among them, the first train and the second train meet the prohibition of marshalling:

The front car curve decelerates in the first train and the second train. or,

The preceding vehicle in the first train and the second train enters the speed limit road section. or,

The first train and the second train cannot run at the same time for the specified time.

For example, the time stipulated by the marshalling is 10 minutes. That is to say, the premise of establishing a flexible formation of two trains is that the trains can run in formation for 10 minutes.

If this train (i.e. the first train) refuses to be formed (in the topological frame, the initial operation sign is prohibited) or the adjacent train (i.e. the second train) refuses to be formed (in the topological frame, the initial operation sign is prohibited) or the two trains do not possess the formation conditions ( The vehicle in front slows down on a curve, the vehicle in front enters the speed-limited road section, and cannot run at the same time for the time specified by the marshalling), then the vehicle in front keeps running automatically (that is, when the first train is in front of the second train, the first train is the vehicle in front, and at this time it is determined to automatically run. driving), the rear car determines the operation curve of the flexible formation according to the operation information of the front vehicle (that is, when the first train is behind the second train, the first train is waiting, at this time, the operation of the flexible formation is determined according to the operation information of the second train curve).

●If it is determined according to the second topology frame that the grouping condition is met, then

2.1 When the first train is behind the second train, the operating curve of the flexible formation is determined according to the operating data of the second train.

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

In addition, after the operation curve of the flexible formation is determined according to the operation data of the second train, it is also confirmed whether the communication is stable, and if it is stable, it is considered that the establishment of the flexible formation is completed.

The way to determine the stability of the communication is: receiving n consecutive communication cycles without packet loss, where n is a preset positive integer, for example, n=10, that is, no packet loss for 10 consecutive communication cycles.

Since the second topology frame sent by the second train will be received based on communication in step 103-3, then the packets of n communication cycles received continuously will not be lost, that is, the second topology frame of n communication cycles will be received continuously Frame packets are not lost. If in step 103-3, based on the communication, the second topology frame sent by the second train is received, and at the same time, the second topology frame sent by the second train is also received, then the messages received continuously for n communication cycles are not lost packets, that is, the second topology frame message received for n communication cycles continuously does not lose the packet, or the second information frame message received for n communication cycles continuously does not lose the packet.

In addition, after communicating with the second train according to the train information list, further includes: In addition, after performing step 103-2, sending the first topology frame and the first information frame to the second train.

Wherein, the "first" in the first information frame is only used for identification, and does not have any other meaning in order to distinguish the information frames sent by other trains. That is to say, the first information frame is an information frame, which 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 can have various relationships with step 103-3, for example, the first train first sends the first topology frame and the second information frame to the second train. An information frame, and then execute step 103-3. For another example, the first train first executes 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 sends the first topology frame and the first information frame to the second train, and then performs step 103-3.

Since there are two groups of adjacent cars in one group of trains (i.e., the previous train and the next train of the first train), for the first train, the second train is a group of adjacent cars, so the first train will have another A group of neighboring cars, in order to clearly distinguish two groups of different neighboring cars, another group of neighboring cars is named the third train. That is, the third train is an adjacent train of the first train, and the third train is different from the second train.

Among them, the "third" in the third train is only used for identification, in order to distinguish other trains, it does not have any other meaning. That is to say, the third train is a group of trains, which is another group of adjacent cars for the first train except the second train.

During the process of sending the first topology frame and receiving the second topology frame, the first train will also receive the third topology frame sent by the third train.

Among them, the third topology frame. The "third" in is only used for identification, in order to distinguish the topological frames of other trains, it does not have any other meaning. That is to say, the third topology frame is a topology frame sent by the third train, that is, the topology frame of the third train.

If the first IP address of the first train is not included in the third topology frame, then

1. Update the first IP address list of the first train according to the positional relationship between the third train and the first train.

specific,

●If the third train is in front of the first train (that is, the third train is the front car of the first train), then

1) Obtain the second IP address list in the second topology frame.

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

●If the third train is behind the first train (that is, the third train is the rear car of the first train), then

1) Obtain the second IP address list in the second topology frame.

2) Putting the second IP address list before the first IP address in the first IP address list to form an updated first IP address list.

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

That is to say, the first train and the second train calculate a new topology frame at the same time during the process of exchanging topology frames. Then put the topological frame IP address list of the rear car (i.e. the second train) behind its own (i.e. the first train) IP address to form a new IP address list to form a topological frame, if the rear car (i.e. the third train) If the received topology frame does not contain the IP address of the car (i.e. the first train), the IP address list of the previous car (i.e. the second train) is placed in front of its own (i.e. the first train) IP address to form a new IP address list Form a topology frame. If the topology frame received by the train is consistent with the topology frame of this train, it is judged that the initial operation is successful. After setting the initial operation completion flag, a new topology frame is sent. When the initial operation of the topology frames received and sent by all trains is completed If the signs are all consistent, then it is determined that the establishment of the flexible formation is completed, and then the mark of formation is completed, and the reference direction of the train is set.

In addition, after the flexible formation is established according to the second topology frame, the vehicle in front will also obtain the control right of the vehicle behind.

For example,

●If the first train is in front of the second train (that is, the first train is the front car), then

A control right acquisition request is sent to the second train, where the control right acquisition request is used to instruct the second train to feed back a control right transfer response.

After receiving the control right transfer response fed back by the second train, a control instruction is sent to the second train, and the control instruction is used to instruct the second train to stop automatic driving.

●If the first train is behind the second train (that is, the first train is the rear car), then

Receive the second train to send the control right acquisition request.

A control transfer response is fed back to the second train.

Receive the control command sent by the second train.

Stop the automatic driving according to the control instruction.

For example, if the first train is the preceding train, when the first train judges that the marshalling completion flag is 1, it sends a control command to the following train (i.e. the second train) to request control. When the following train (i.e. the second train) judges the formation The completion flag is 1 and after receiving the control command from the preceding vehicle (i.e. the first train), send the control transfer response to the preceding vehicle (i.e. the first train); the preceding vehicle (i.e. the first train) receives the following vehicle (i.e. the second Train) sends specific control commands to the rear car (i.e. the second train) after the response frame, and the rear car (i.e. the second train) executes the control order of the front vehicle (i.e. the first train) after receiving it and no longer drives automatically.

For another example, if the first train is the following train, after receiving the preceding train (i.e. the second train) requesting to obtain the control right, the group completion flag is 1 and sends a control transfer response to the preceding train (i.e. the second train); The front car (that is, the second train) sends specific control commands to the rear car (that is, the first train) after receiving the response frame from the rear car (that is, the first train), and the rear car (that is, the first train) executes the front car after receiving the response frame. (i.e. the second train) control commands and no longer autopilot.

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, it can be used WIFI or radar for communication.

Step 104, perform interval control on flexible grouping.

After step 103 is executed, a flexible formation has been established between the first train and the second train, and in step 104 the flexible formation will be controlled. During control, the interval control of the front vehicle on the flexible formation is reflected in: the front vehicle will determine the traction force/braking force at each moment according to the traction force/braking force information of the rear vehicle, and send the determined traction force/braking force to the rear vehicle. The interval control of the flexible formation by the trailing vehicle is reflected in: sending its own traction force/braking force information to the preceding vehicle, and executing the traction force/braking force determined by the preceding vehicle. If the first train is ahead of the second train, the first train is the leading train, and if the first train is behind the second train, the first train is the following train.

The following describes how the first train performs interval control on the flexible formation for the two situations in which the first train is located in front of the second train and the first train is located behind the second train.

The first case: the first train is located in front of the second train, and now the first train is the front car, and the second train is the rear car. The first train needs to determine the traction force/braking force at each moment according to the traction force/braking force information of the following vehicle, and send the determined traction force/braking force to the following vehicle. The second train needs to send its own traction/braking force information to the first train, and implement the traction/braking force determined by the first train.

Specifically, the first train will

A.1 Determine the current operational phase of the flexible marshalling.

A.2 Perform interval control on flexible marshalling according to the current operating phase.

●If the current running phase is not the parking phase, then

Calculate the traction force/braking force at the next moment, and perform interval control according to the traction force/braking force at the next moment.

●If the current running phase is the parking phase, then

When the distance to the second train is not less than the stop interval, decelerate and stop based on the single-vehicle running curve, and calculate the traction/braking force at the next moment, and perform interval control according to the traction/braking force at the next moment.

When the distance to the second train is less than the stop interval, after it is determined that the braking condition is met, the braking distance is calculated according to the current speed. Whenever the ground position information is obtained, the current braking rate is calculated based on the braking distance and the obtained ground position information, deceleration braking is performed according to the current braking force, and the traction force/braking force at the next moment is calculated, according to the traction force at the next moment /Braking force for interval control.

Regardless of the stage of the current operation, as long as the traction/braking force at the next moment is calculated, the calculation method is as follows: obtain the traction/braking force information of the second train, and calculate the traction/braking force at the next moment according to the traction/braking force information .

Among them, according to the traction force/braking force information, the process of calculating the traction force/braking force at the next moment is:

a.1 Calculate the speed deviation according to the speed-distance curve obtained in advance, the distance to the second train and the current speed.

a.2 Determine the minimum distance for interval control.

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

S _min =T _sum *V _back +ΔS+d.

in,

S _min is the minimum distance for interval control.

T _sum is the delay time, T _sum =t _c +t _p +t _b , t _c is the communication interruption time, t _p is the algorithm execution time, t _b is the time from when the brake command is issued to when the brake is applied.

V _back is the running speed of the second train.

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

d is the safety margin, for example, d is 2 meters.

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

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

The traction/braking force at the next moment is sent to the flexible formation control unit of the second train through the flexible formation control unit. To make the second train transmit the traction force/braking force at the next moment to the CCU (Central Control Unit, central control unit) of the second train through the flexible formation control unit, apply the traction force/braking force at the next moment by the CCU of the second train, In order to control the speed of the second train.

The second situation: the first train is behind the second train, and now the second train is the front car, and the first train is the rear car. The second train needs to determine the traction force/braking force at each moment according to the traction force/braking force information of the following vehicle, and send the determined traction force/braking force to the following vehicle. The first train needs to send its own traction/braking force information to the second train, and implement the traction/braking force determined by the second train.

Specifically, the first train will send the traction force/braking force information to the second train, so that the second train can calculate the traction force/braking force at the next moment according to the traction force/braking force information, and perform interval control according to the traction force/braking force at the next moment .

In addition, the traction/braking force at the next moment sent by the second train will also be received through the flexible formation control unit. The traction/braking force at the next moment is forwarded to the CCU of the second train through the flexible formation control unit. The traction/braking force of the next moment is applied by the CCU in order to control the speed of the first train.

Through the process of step 104 for interval control of the flexible formation, on the basis of wireless formation and automatic operation among multiple trains, it is possible to realize that the trains in the formation are taken as a whole and uniformly controlled by the leading train formation. Mainly after the trains are organized, the interval control curve is calculated, and the trains are controlled to maintain the running interval during the flexible formation process.

For example, according to real-time status signals such as vehicle position, real-time speed, braking distance, and braking system working conditions, the vehicle in front controls the speed of trains in the formation in combination with the braking distance of the train, maintains the distance between trains in a flexible formation, and ensures that the It can brake safely and avoid rear-end collision.
