The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.

A train formation method, a formation controller, and a train according to an embodiment of the present invention will be described below with reference to the drawings.

Fig. 1 is a schematic flow chart of a train formation method according to an embodiment of the present invention. As shown in fig. 1, the train formation method includes the steps of:

s101, when a regrouping instruction is received, sequentially transmitting a self-detection communication message to the grouping controllers of all the carriages through the grouping controllers of the adjacent carriages by the grouping controller on the train leading carriage so that the grouping controller of each carriage sends the number of the carriage to the grouping controller of the adjacent carriage, and judging whether the number of the carriage is wrong according to the received number of the adjacent carriage; the leading carriage is a head carriage or a tail carriage which is provided with a GPS positioner and an acceleration sensor on the train.

The execution main body of the train marshalling method provided by the invention is a marshalling controller, and the marshalling controller can be specifically a hardware device arranged on each carriage of the train or a hardware device arranged in a gateway of each carriage of the train. If the group controllers are not integrated into the gateways of the associated cars, the group controllers of adjacent cars may be interconnected in pairs in a network. As shown in fig. 2, a schematic diagram of a train when the consist controller is not integrated into the gateway of the car to which it belongs. In fig. 2, the train includes three cars, a head car, a middle car and a tail car. A plurality of devices, such as node 1, node 2, node 3, node N, etc., are connected in the vehicle network of each car.

If the group controller is integrated into the gateway of the car, the gateways of adjacent cars can be interconnected in pairs in a network, that is, when a certain car needs to communicate with non-adjacent cars, the data needs to be sequentially transmitted to the non-adjacent cars through the adjacent gateways. As shown in fig. 3, a schematic diagram of a train is shown when the consist controller is integrated into the gateway of the car.

In this embodiment, the train originally includes a head carriage, a first middle carriage, and a tail carriage, and after a second middle carriage is added, the train includes a head carriage, a first middle carriage, a second middle carriage, and a tail carriage. Wherein, a GPS positioner and an acceleration sensor are arranged on the head carriage and the tail carriage. The head carriage is used as a leading carriage. After newly adding carriages, when receiving a regrouping command, the marshalling controller on the head carriage can transmit the self-checking communication message to the first middle carriage, transmit the self-checking communication message to the second middle carriage through the first middle carriage, and transmit the self-checking communication message to the tail carriage through the first middle carriage and the second middle carriage; and the grouping controllers of the four carriages send the serial numbers of the carriages to the grouping controllers of the adjacent carriages according to the self-checking communication message, and judge whether the serial numbers of the carriages are wrong or not according to the received serial numbers of the adjacent carriages.

Specifically, in this embodiment, when receiving the self-checking communication packet, the group controller of the first middle carriage sends the number of the first middle carriage to the head carriage and the second middle carriage, and receives the number of the head carriage and the number of the second middle carriage, where the number of the head carriage is 1, the number of the second middle carriage is X, the number of the first middle carriage is 2, and the number of the first middle carriage is determined to be correct according to the number of the head carriage and the number of the second middle carriage. When receiving the self-checking communication message, the grouping controller of the second middle carriage sends the serial number of the second middle carriage to the first middle carriage and the tail carriage, receives the serial number of the first middle carriage and the serial number of the tail carriage, the serial number of the first middle carriage is 2, the serial number of the second middle carriage is X, the serial number of the tail carriage is 3, and the serial number of the second middle carriage is determined to be wrong according to the serial number of the first middle carriage and the serial number of the tail carriage. And reporting the judgment result to a grouping controller of the head compartment when the error occurs.

In addition, in the present embodiment, only the leading car or the trailing car provided with the GPS locator and the acceleration sensor may be used as the leading car. For example, if the tail car is not provided with a GPS locator and an acceleration sensor, the tail car may not be used as a lead car.

In addition, it should be noted that the regrouping command may be in the form of a command, or in the form of a hard-wire trigger switch signal, and may be set according to actual needs. When the re-consist command is in the form of a hard-wire trigger switch signal, it is also necessary to provide a hard-wire trigger switch circuit in the lead car or the tail car of the train.

S102, judging whether a judgment result sent by the grouping controller of each compartment on the train is received or not, wherein the judgment result is sent when the number of the compartment to which the grouping controller of each compartment on the train belongs is wrong.

And S103, if the judgment result is received, the grouping controller on the leading carriage determines that the train has the conditions of increasing or decreasing carriages and/or replacing carriages, and sends an adjustment communication message to the grouping controller of the carriage to be numbered and adjusted according to the judgment result, so that the grouping controller of the carriage to be numbered and adjusted adjusts the number of the carriage according to the number of the adjacent carriage, and the numbers of the carriages of the train are sequentially increased.

In this embodiment, the train originally includes a head carriage, a first middle carriage, and a tail carriage, and after a second middle carriage is added, the train includes a head carriage, a first middle carriage, a second middle carriage, and a tail carriage. Wherein, the head carriage is used as a leading carriage. And the marshalling controller on the head carriage determines the carriages to be numbered and adjusted to be a second middle carriage and a tail carriage according to the judgment result, so that adjusting communication messages are sent to the marshalling controller of the second middle carriage and the marshalling controller of the tail carriage, so that the marshalling controller of the second middle carriage and the marshalling controller of the tail carriage adjust the numbers of the carriages according to the numbers of the adjacent carriages, and the numbers of the carriages of the train are sequentially increased.

Specifically, the process of adjusting the serial numbers of the carriages to which the group controller of the second middle carriage belongs according to the serial numbers of the adjacent carriages may specifically be that whether the serial number of the first middle carriage is smaller than the serial number of the tail carriage is judged, and since 2 is smaller than 3, the serial number of the second middle carriage is set to 3 according to the serial number of the first middle carriage, and then the serial number of the tail carriage is set to 4 according to the serial number of the second middle carriage.

Further, on the basis of the foregoing embodiment, after step 103, the method may further include: judging whether the current running direction of the train changes or not; and if the current running direction of the train is changed and the current running direction of the train is opposite to the positive direction of the leading carriage, sending a re-marshalling command to the marshalling controller of the carriage at the other end corresponding to the leading carriage on the train.

In this embodiment, if the current running direction of the train changes and the current running direction of the train is opposite to the positive direction of the lead car, it can be determined that the train is in a reverse running state.

Further, on the basis of the foregoing embodiment, after step 103, the method may further include: the method comprises the following steps that a grouping controller on a train leading carriage periodically obtains the serial numbers of all carriages on a train; and reporting the serial numbers of all the carriages to a master controller of the train so that the master controller can judge whether the serial numbers of all the carriages on the train change or not, and sending a regrouping instruction to a marshalling controller on a leading carriage when the serial numbers of all the carriages on the train change.

Therefore, in this embodiment, when the grouping controller on the leading car of the train receives a re-grouping instruction, it needs to determine whether the re-grouping instruction originates from the grouping controller of the car at the other end corresponding to the leading car on the train or from the master controller, according to the determination result provided by the grouping controller of each car; if the re-marshalling command is determined to be from the marshalling controller of the carriage at the other end corresponding to the leading carriage on the train, the situation that the train increases or decreases the carriage or replaces the carriage is indicated; if the re-marshalling command is determined to be from the master controller, the situation that the running direction of the train is changed is shown.

Fig. 4 is a schematic flow chart of another train formation method according to an embodiment of the present invention, as shown in fig. 4, based on the embodiment shown in fig. 1, the method further includes:

and S104, if the judgment result is not received, the grouping controller on the leading carriage of the train determines that the train has the condition of changing the running direction, resets the number of the leading carriage to a zero value, and sequentially transmits the reset communication message to the grouping controllers of all the carriages through the grouping controllers of the adjacent carriages, so that the grouping controllers of all the carriages reset the numbers of the carriages to the zero value according to the reset communication message.

In this embodiment, if the determination result is not received, the group controller on the lead car of the train may determine that the train does not have the situation of increasing or decreasing the cars or replacing a certain section or part of the cars, but the train running direction changes, that is, the train runs in the opposite direction.

S105, setting the number of the leading carriage to be N, sending the N value to a gateway controller of the leading carriage, sending a grouping communication message carrying the N value to a grouping controller of the next carriage, so that the grouping controller of the next carriage sets the number of the carriage to be N +1, sends the value of N +1 to the gateway controller of the carriage, and sends the grouping communication message carrying the value of N +1 to the grouping controller of the next carriage until the numbers of all the carriages of the train are completely set; wherein N is an integer.

In this embodiment, specifically, the train includes four cars, which are a head car, a first middle car, a second middle car, and a tail car respectively. The head carriage is used as a leading carriage, when the current running direction of the train is the same as the positive direction of the head carriage, the numbering controller of the head carriage sets the number of the head carriage to be N, N is 1, and the N value is sent to the gateway controller of the head carriage, so that the gateway controller carries the number of the head carriage when transmitting data; the marshalling controller of the head carriage sends the marshalling communication message carrying the N value to the marshalling controller of the first middle carriage; the marshalling controller of the first middle carriage sets the serial number of the first middle carriage to be N + 1-2, sends the value of N +1 to the gateway controller of the first middle carriage, and sends the marshalling communication message carrying the value of N +1 to the marshalling controller of the second middle carriage; the marshalling controller of the second middle carriage sets the serial number of the second middle carriage to be N + 2-3, sends the value of N +2 to the gateway controller of the second middle carriage, and sends the marshalling communication message carrying the value of N +2 to the tail carriage; the marshalling controller of the tail carriage sets the number of the tail carriage to be N + 3-4, and sends the value of N +3 to the gateway controller of the tail carriage.

In this embodiment, when the train has a changed traveling direction, it is necessary to ensure that the lead car that has received the re-formation command is the current lead car first, that is, it is necessary to determine whether the positive direction of the lead car is the same as the current traveling direction of the train first, and therefore, step 105 may further include: acquiring the current running direction of the train; and judging whether the current driving direction is the same as the positive direction of the leading carriage. Correspondingly, in step 105, if the current driving direction is the same as the positive direction of the leading car, setting the number of the leading car to be N, sending the value of N to the gateway controller of the leading car, and sending the grouping communication message carrying the value of N to the grouping controller of the next car, so that the grouping controller of the next car sets the number of the car to be N +1, sends the value of N +1 to the gateway controller of the car to be N, and sends the grouping communication message carrying the value of N +1 to the grouping controller of the next car until the numbers of all cars of the train are completely set; wherein N is an integer.

In this embodiment, the GPS locator may be configured to collect position information of the lead car and send the position information to the grouping controller connected to the GPS locator. The acceleration sensor can be used for collecting the acceleration information of the leading carriage and sending the acceleration information to the grouping controller connected with the acceleration sensor. The grouping controller can acquire the current driving direction of the train by combining the position information and the acceleration information of the leading carriage.

In this embodiment, the position information and the acceleration information of the lead car of the train may be acquired when the train starts to operate from a stationary state, that is, within a period of time when the train starts to operate. The marshalling controller can detect the position of the train in real time through the GPS positioner, and when the position of the train begins to change and the acceleration is a non-zero value, the position information and the acceleration information of the leading carriage of the train are acquired.

In this embodiment, the positive directions of the head compartment and the tail compartment may be set in advance. For example, the head car takes the train running direction as the positive direction; the tail carriage takes the train running reverse direction as the positive direction.

In addition, when the current traveling direction of the train is opposite to the forward direction of the lead car, a re-formation command is transmitted to the formation controller of the other car corresponding to the lead car on the train.

Further, after step 105, if the current traveling direction of the train changes and the current traveling direction of the train is opposite to the positive direction of the lead car, the consist controller of the lead car may send a re-consist command to the consist controller of another car corresponding to the lead car on the train, so that the car of the other end can be used as the lead car and the car of the other end can continue to execute the content of step 101.

In this embodiment, in a scenario where both the head car and the tail car can be used as the lead car, if the lead car of the train is the head car, the car at the other end corresponding to the lead car is the tail car; if the leading car of the train is the tail car, the car at the other end corresponding to the leading car is the head car. In a scenario where the head car may be the lead car and the tail car may not be the lead car, the train does not travel in the opposite direction, and therefore there is no concern about sending a re-consist command to the consist controller of the car at the other end of the train corresponding to the lead car.

According to the train marshalling method provided by the embodiment of the invention, when a re-marshalling instruction is received, the marshalling controller on the train leading carriage sequentially transmits the self-detection communication message to the marshalling controllers of all carriages through the marshalling controllers of the adjacent carriages, and judges whether the number of the carriage is wrong according to the received number of the adjacent carriage; when no error occurs, the marshalling controller on the leading carriage of the train determines that the train has the condition of changing the running direction, resets the serial number of the leading carriage to a zero value, and sequentially transmits the reset communication message to the marshalling controllers of all carriages through the marshalling controllers of the adjacent carriages; when the current driving direction is the same as the positive direction of the leading carriage, the number of the leading carriage is set to be N, the value of N is sent to a gateway controller of the leading carriage, and a grouping communication message carrying the value of N is sent to a grouping controller of the next carriage, so that the grouping controller of the next carriage sets the number of the carriage to be N +1, the value of N +1 is sent to the gateway controller of the carriage to be N +1, and the grouping communication message carrying the value of N +1 is sent to the grouping controller of the next carriage until the numbers of all the carriages of the train are completely set; n is an integer, so that when the grouping controller on the train lead carriage receives a regrouping instruction, the lead carriage and other carriages of the train are controlled to automatically group, the automatic grouping of the train is realized, the efficiency and the accuracy of carriage number configuration are improved, and the running efficiency of the train is improved.
