Description

Train sequencing method and system and locomotive controller

Technical Field

The application relates to the technical field of vehicle control, in particular to a train sequencing method and system and a locomotive controller.

Background

Along with the development of social economy, the contradiction between the railway transportation energy and the transportation volume is more and more prominent, if the potential synergy is further dug, the transportation energy is released, the condition of the shortage of bulk material transportation is relieved, and the running of a large and heavy-load freight train is a necessary choice for railway departments. However, when a long and heavy-duty train brakes, the wave velocity of air braking can only reach about 200m/s, and the train with the length exceeding kilometers is controlled by a locomotive, the front and rear braking is necessarily asynchronous, the braking distance is lengthened, brake shoes, wheels, traction rods, car couplers and the like are excessively worn, the maintenance and application cost is increased, more importantly, huge car coupler force and severe longitudinal impulse are generated, the train is difficult to operate by a driver, and the accidents of train hook breakage and derailment are easy to occur. In addition, when the heavy-duty train runs on a long descending ramp, the vehicle brake has no stage relieving function, the inflation time is too long, the train is easy to lose control, and the safety is threatened.

In order to deal with the situation, an Electronically Controlled Pneumatic brake (ECP) is proposed, which is divided into two schemes, namely a wired scheme and a wireless scheme, and the two schemes are different in information transmission mode, wherein the wired ECP has a wide application range and a mature technology. Wired ECP is where a double power line is placed across the locomotive and vehicle on the entire train. With the power line, power from the locomotive can be transmitted to the vehicle, while bidirectional data exchange is performed between the locomotive and the vehicle with the power line. Before data exchange, the marshalling condition and the marshalling sequence of the train need to be known, and the position and the direction of the train need to be accurately positioned, so that the returned information can be correctly displayed. And the knowledge of the train marshalling condition and the marshalling sequence is also one of the preconditions for fault diagnosis, and is an important step for ensuring the safe and stable operation of the long and large marshalling heavy-duty train.

The current ECP train sequencing system mainly comprises a sequencing circuit, a switch load and a current sensor. After the sequencing has begun, the switchable load is activated to produce current pulses, and the position and sequence of the vehicle is determined based on the difference in the pulses received by each module. The sequencing method not only needs to add a special hardware circuit, but also needs to be provided with a special sequencing power supply. In addition, it is most critical that the current sorting method is long in use and the success rate is to be improved, and when the train consist is long, the train sorting operation based on the method makes the preparation work before the ECP is used become more tedious and complicated.

The following examples are intended to illustrate the details.

In order to improve the efficiency and accuracy of train sequencing and further improve the reliability of data exchange in a train, the present embodiment provides a train sequencing method in which an execution subject is a locomotive controller, where the locomotive controller includes but is not limited to a server, as shown in fig. 1, the method specifically includes the following steps:

step 100: and acquiring respective average position coordinates of the locomotive and the plurality of groups of vehicles in the target train.

Specifically, the locomotive controller may send a sequencing start instruction to at least one vehicle controller corresponding to each group of vehicle groups in the target train; the vehicle controller acquires the position coordinates of the two ends of the vehicle group acquired by the satellite positioner corresponding to the vehicle controller according to the sequencing starting instruction, wherein the position coordinates of the two ends of the vehicle group are the front position coordinates and the rear position coordinates of the vehicle group; the vehicle controller determines the average position coordinates of the vehicle group according to the position coordinates of the two ends of the vehicle group and returns the average position coordinates to the locomotive controller; each vehicle group corresponds to one or more vehicles.

Step 200: and determining the sequencing result of each group of vehicles in the target train according to the respective average position coordinates of the locomotive and each group of vehicles.

Specifically, the order of the vehicle groups in the target train may be determined based on the respective average position coordinates of the locomotive and the vehicle groups.

Step 300: and judging whether each group of vehicle groups contains the only vehicle, if so, sequencing the vehicles in the target train according to the sequencing result of the vehicle groups.

Specifically, if the vehicle groups and the vehicles are in one-to-one correspondence, the vehicles in the target train may be sorted according to the order of each vehicle group in the target train, that is, the order of each vehicle group in the target train may be used as the order of each vehicle. Furthermore, the position information can be transmitted by directly sending the short message to the locomotive controller through the vehicle satellite positioner based on the short message function in the Beidou system without depending on a power line, so that the limitation of the bandwidth and the transmission speed of the power line can be broken, train sequencing can be completed more quickly, and the sequencing speed is increased by multiple times. Further, if each group of vehicles comprises a unique vehicle, whether the distance between the vehicles is proper or not can be judged, and if yes, the vehicles in the target train are sequenced according to the sequencing result of the vehicle groups.

In order to achieve the determination of the end of the train group close to the locomotive based on the efficiency of train sequencing, and further improve the accuracy of train data exchange, referring to fig. 2, in an embodiment of the present application, after step 200, the method further includes:

step 400: the method includes the steps of obtaining front end position coordinates and rear end position coordinates of a preset number of vehicle groups.

Specifically, the preset number may be set according to actual needs, and the application is not limited thereto. The front end position coordinates and the rear end position coordinates of each group of vehicle groups can be acquired while the average position coordinates of each group of vehicle groups are acquired, and the front end position coordinates and the rear end position coordinates of the front N groups of vehicle groups are selected.

Step 500: and determining the distances from the front end and the rear end of each group of the preset number of vehicle groups to the locomotive respectively according to the average position coordinate of the locomotive, and the front end position coordinate and the rear end position coordinate of each group of the preset number of vehicle groups.

Specifically, the distances from the front end and the rear end of each of the preset number of vehicle groups to the locomotive may include: the distance from the front end of each of the predetermined number of vehicle groups to the locomotive and the distance from the rear end of the group of vehicles to the locomotive.

Step 600: determining one end of each vehicle group close to the locomotive according to the number of the first vehicle groups and the number of the second vehicle groups; the first vehicle group is a vehicle group of which the distance from the front end to the locomotive is greater than the distance from the rear end to the locomotive in the preset number of vehicle groups, and the second vehicle group is a vehicle group of which the distance from the front end to the locomotive is less than the distance from the rear end to the locomotive in the preset number of vehicle groups.

Specifically, if the number of the first vehicle groups is greater than the number of the second vehicle groups, it may be determined that each vehicle group is the rear-end-approaching locomotive, and if the number of the first vehicle groups is less than the number of the second vehicle groups, it may be determined that each vehicle group is the front-end-approaching locomotive. For a train, each vehicle is identical at the end near the locomotive; the front end of each vehicle group is close to the locomotive, namely the front end of each vehicle in the vehicle group is close to the locomotive, and the rear end of each vehicle group is close to the locomotive, namely the rear end of each vehicle in the vehicle group is close to the locomotive.

To further improve the efficiency of train sequencing, referring to fig. 2, in an embodiment of the present application, after determining whether each vehicle group includes a unique vehicle in step 200, the method further includes:

step 700: and if each group of vehicles comprises a plurality of vehicles, determining the sequencing result of each vehicle in the target train according to the sequencing result of the vehicle group and one end of each group of vehicles close to the locomotive.

Specifically, for a vehicle group including a plurality of vehicles, the position information of the vehicles in the group is known, for example, xx01, xx02, xx03 and the like are predetermined in the order from the front end to the rear end in the vehicle group, and the ID and the position information of the vehicles in each group of vehicle groups may be stored in advance in the locomotive controller; the method comprises the steps that the average position coordinates of a plurality of groups of vehicle groups are obtained, meanwhile, the ID of each group of vehicle groups can be obtained, and if each group of vehicle groups comprises a unique vehicle, the ID of each vehicle group can be the vehicle ID; if each group of vehicles comprises a plurality of vehicles, the ID and the position information of the vehicles of the group of vehicles can be obtained from the locomotive controller according to the ID of the group of vehicles; thus, after determining that each group of vehicles is near one end of the locomotive, the order of the vehicles within the group of vehicles may be determined based on pre-stored location information for the vehicles in each group of vehicles; the order of the individual vehicles in the target train may be determined based on the order of the vehicles within the vehicle group and the results of the ranking of the vehicle groups.

For example, the vehicle group ranking result of the target train is: vehicle group No. 1 and vehicle group No. 2; the position information of the vehicles in the vehicle group No. 1 is as follows: the vehicle IDs from the front end to the rear end of vehicle group No. 1 are xx01, xx02, and xx03 in this order, and the position information of the vehicles in vehicle group No. 2 is: the vehicle IDs from the front end to the rear end of the vehicle group 2 are xx04, xx05 and xx06 in sequence, and if each vehicle group is a front-end-approaching locomotive, the vehicle sequencing result can be determined as follows: vehicles xx01 through xx06 are in sequence vehicle nos. 1 through 6; if each group of vehicles is the rear end close to the locomotive, the vehicle sequencing result can be determined as follows: vehicles xx03, xx02, xx01, xx06, xx05 and xx04 are vehicle nos. 1 to 6 in this order.

In order to avoid the influence of errors in coordinates of the collected positions on the sorting result and improve the reliability of the sorting result, in an embodiment of the present application, step 300 includes:

step 301: and judging whether each group of vehicle groups contains the only vehicle, if so, judging whether the target train has a vehicle group to be confirmed, wherein the distance between the target train and the previous vehicle group is less than or equal to a distance threshold value.

Specifically, the vehicle group to be confirmed is a vehicle group in which the distance between the vehicle group immediately before the vehicle group in each vehicle group is equal to or less than a distance threshold value.

Step 302: if the vehicle group to be confirmed exists, the average position coordinates of the vehicle group to be confirmed are obtained again until the distance between the vehicle group to be confirmed and the vehicle group before the vehicle group to be confirmed is larger than the distance threshold value.

Specifically, the grouping satellite positioner of the vehicle group to be confirmed can acquire the position coordinates of the front end and the rear end of the vehicle group again, and after the average position coordinates are obtained by at least one vehicle controller in the vehicle group according to the acquired position coordinates of the front end and the rear end, the average position coordinates are sent to the locomotive controller.

Step 303: and re-sequencing the vehicle groups according to the obtained average position coordinates of the vehicle groups to be confirmed.

Specifically, after replacing the original average position coordinates of the vehicle group to be confirmed with the average position coordinates of the vehicle group to be confirmed acquired again, the vehicle groups may be reordered according to the respective average position coordinates of the locomotive and each vehicle group.

Step 304: and sequencing the vehicles in the target train according to the result of the reordering of the vehicle group.

It can be understood that if each vehicle group includes a unique vehicle, and there is no vehicle group to be confirmed in the target train whose distance from the vehicle group immediately before the unique vehicle is less than or equal to the distance threshold, the vehicles in the target train may be sorted according to the sorting result of the vehicle groups.

To further improve the reliability of train sequencing, in one embodiment of the present application, the step 200 comprises:

step 201: according to the respective average position coordinates of the locomotive and each group of vehicle groups, taking the vehicle group closest to the locomotive as a head vehicle group, taking the head vehicle group as a target vehicle group, and executing a sequencing step, wherein the sequencing step comprises the following steps: and according to the average position coordinates of the target vehicle group and the unordered vehicle groups, taking the vehicle group which is closest to the target vehicle group and is unordered as the next vehicle group.

Step 202: and if the unsorted vehicle group exists currently, taking the next vehicle group as a target vehicle group, and executing the sorting step again.

It is to be understood that after the next vehicle group is determined in step 201, the next vehicle group is changed from the unsorted vehicle group to the sorted vehicle group; and if the unsorted vehicle group does not exist currently, stopping the current operation to obtain the sorting result of the vehicles in the target train.

For example, the average position coordinates are calculated from the backward direction of the locomotive, the vehicle group closest to the locomotive is the No. 1 vehicle group, the vehicle group closest to the No. 1 vehicle group is the No. 2 vehicle group, and the like, and a primary sequencing result is determined; if each group of vehicles comprises a unique vehicle, the vehicle contained in the vehicle group No. 1 is the vehicle No. 1, the vehicle No. 2 of the vehicle contained in the vehicle group No. 2, and so on.

In order to further improve the accuracy of train sequencing, the application example of the train sequencing method is provided, and a plurality of insurance mechanisms are considered, in the application example, a satellite positioner is respectively arranged in front of and behind each locomotive and each vehicle group, the position coordinates of the front end and the rear end of each vehicle group are collected, and the middle value of the two is used as the average position coordinate for sequencing so as to reduce errors; a controller is mounted on the locomotive and each vehicle separately. After the train set is completed, the sequencing process is started, as described in detail below with reference to fig. 3:

step S1: broadcasting a starting sequencing instruction by the locomotive; step S2: collecting coordinate information by the vehicle; step S3: the vehicle returns coordinates; step S4: the locomotive carries out vehicle group processing; step S5: judging whether secondary confirmation is needed, if so, executing the step S6, otherwise, executing the step S7; step S6: performing secondary confirmation; step S7: a grouping is determined.

Specifically, a sequencing start command is broadcast by the locomotive controller over the power line to all vehicle controllers. If each vehicle group contains the only vehicle, the vehicle controller returns the ID, the front position coordinate, the rear position coordinate and the average position coordinate after receiving the sequencing starting command. After receiving and confirming the vehicle message, the locomotive controller starts to calculate from the rear direction of the locomotive by using the average position coordinate, the nearest vehicle is the No. 1 vehicle, then the vehicle closest to the No. 1 vehicle is the No. 2 vehicle, and so on, and determines a sequencing result. And comparing the front position coordinates and the rear position coordinates of the front N vehicles with the average position coordinates of the locomotive respectively, and determining whether the front position coordinates of the vehicles are closer to the locomotive or the rear position coordinates of the vehicles are closer to the locomotive according to statistical data. Assuming that there are more vehicles with front position coordinates close to the locomotive, it is said that the front is toward the locomotive when the vehicles are grouped (because the direction of the vehicles is consistent). And secondly, performing secondary confirmation on the marshalling result, and acquiring the coordinate position of the vehicle with the distance less than 5 meters again until the distance between the two vehicles is more than 5 meters, and updating the sorting result if the distance is different from the primary sorting.

If each vehicle group comprises two vehicles or three vehicles, such as a C80B open vehicle, the vehicles are fixed marshalling, the vehicles can be a node according to one vehicle group, and any vehicle controller in each vehicle group returns the ID, the front end position coordinate, the rear end position coordinate and the average position coordinate of the vehicle group; after receiving and confirming the vehicle message, the locomotive controller starts to calculate from the backward direction of the locomotive by using the average position coordinate, the nearest is the No. 1 vehicle group, then the nearest to the No. 1 vehicle group is the No. 2 vehicle group, and so on, and determines a sequencing result. And then, respectively comparing the front position coordinates and the rear position coordinates of the front N groups of vehicle groups with the average position coordinates of the locomotive, and determining whether the front position coordinates or the rear position coordinates of the vehicle groups are closer to the locomotive or closer to the locomotive according to statistical data. If the position coordinates of the front end are close to a plurality of vehicle groups of the locomotive, the front end faces the locomotive when the vehicle groups are shown; the order of the individual vehicles can be confirmed according to the vehicle group order and the vehicle group direction; for the condition that the vehicle group comprises a plurality of vehicles, the position distance between two adjacent vehicles is almost certainly larger than 5 meters, so that only one-time vehicle group and vehicle group direction confirmation according to the group is needed to be completed, then the vehicle group sequencing is expanded, the condition of secondary confirmation is not needed to be triggered, and the sequencing speed can be greatly improved.
