Description

Technical Field

[0001] The present invention relates to the technical field of railway shunting, and in particular to a railway shunting anti-collision warning method and system. Background Art

[0002] Railway shunting is an important operation link in railway transportation production, involving complex links such as dispatching commanders, outdoor shunting personnel, train inspection, cargo inspection, shunting locomotives, and vehicles. In order to ensure the standardization of shunting operations, the National Railway Administration has promulgated railway industry standards such as TB / T2834-2016, TB / T 3505-2018, and TB / T 3441-2016. China State Railway Group Co., Ltd. has issued many standards and documents such as "Management Measures for Preventing Locomotives and Vehicles from Running Away" TG / CW204-2006, "Management, Use and Maintenance Methods of Wireless Shunting Lighting and Display Equipment" TG / CW218-2012, "Vehicle-Machine Joint Control Operation" TG / CW223-2009 and "Vehicle Safety Management Rules" (China Railway General Transport

[2016] No. 159).

[0003] When the locomotive is running to the station, the shunting in the freight yard will disassemble the incoming carriages according to the tasks on the plan sheet based on the locomotive's train number, cargo type, and track number, and transfer the disassembled carriages to the designated track of the freight yard through shunting according to the contents of the plan sheet. In actual work, shunting needs to push some carriages to the designated track for parking. Since the shunting is located behind the moving direction of the carriages to be parked, the distance between the frontmost carriage and the original carriages on the track cannot be effectively observed when the shunting pushes the carriages to be parked, so there is a risk of carriage collision. At present, shunting operations are usually carried out by the team members on-site to direct the shunting driver, which will lead to increased labor costs. At the same time, since the spacing needs to be judged manually, there is a large degree of subjectivity, and the arrangement of the carriages on the track cannot be accurately planned, which reduces the safety of shunting operations and reduces the execution efficiency of shunting operations.

[0053] Example 1

[0054] refer to Figure 1 This embodiment provides a railway shunting anti-collision warning method, comprising the following steps:

[0055] S1. Obtaining information on shunting on the same track, information on carriages to be parked, and information on existing carriages;

[0056] Among them, the shunting information includes the real-time position of the shunting; the information of the carriages to be parked includes the length of the carriages to be parked, the change length of the carriages to be parked and the number of carriages to be parked; the information of the existing carriages includes the position of the signal on the same track, the position of the existing carriages and the total length L3 of the existing carriages.

[0057] Specifically, the real-time position of the shunting train is the real-time position of the end of the shunting train facing the signal on the corresponding track. The real-time position of the shunting train can be represented by taking the track entry end as the 0 point coordinate and representing the real-time position of the shunting train according to the distance the shunting train travels on the track, so that the real-time position of the shunting train is more intuitive and reliable.

[0058] The information of the carriages to be parked coupled with the shunting train is usually obtained when the main locomotive enters the station. The length of a single carriage to be parked and its change length are obtained. The number of carriages to be coupled with the shunting train can be obtained through the issued task order.

[0059] refer to Figure 2 , the existing carriage belongs to the carriage to be parked that is transferred to the track during the first shunting operation. Since there is no carriage in front of the track during the first shunting operation, there is no need to pay attention to the risk of collision between carriages. Therefore, the present invention is aimed at the situation where there is an existing carriage on the track during the shunting operation; the information of the existing carriage includes the position of the signal on the track. Since the position of the signal is relatively fixed, it can be used as a reference standard for distance calculation; the position of the existing carriage refers to the position of the side close to the end of the signal on the track. Since the existing carriage is used as the carriage to be parked during the above-mentioned first shunting operation, its carriage The number of cars, the length of cars and the length change of cars can all be obtained from the issued plan sheet, so the distance L6 between the shunting car and the signal is determined according to the position of shunting car A and the position between the signal during the first shunting operation, and then the total length L7 of the first car to be parked is calculated according to the product of the length of the car to be parked during the first shunting operation, the number of cars to be parked and the length change of the car to be parked, so that after completing the first shunting operation, the car to be parked is the existing car, and the distance L8 between the existing car and the signal is L8=L6-L7, and then the position of the existing car is obtained according to the position of the signal.

[0060] Since the shunting operation needs to be completed more than once or twice to complete the contents of the plan, after completing each shunting operation of the carriage to be parked, the carriage to be parked is used as the existing carriage on the track. The position of the existing carriage at this time is the end position close to the signal, and the length of the existing carriage is the sum of the lengths of all the existing carriages on the track; since the shunting operation also includes transporting the existing carriages on the track, at this time, since shunting A is coupled with the carriages close to the entry or exit port of the track and is shunted out of the freight yard in turn, the shunting driver can normally judge the distance from the existing carriage when coupling the existing carriage, so this situation still does not belong to the scenario applicable to the present invention.

[0061] S2. Calculate the carriage spacing between the carriage to be parked and the existing carriage on the same track based on the shunting information, the information of the carriage to be parked and the information of the existing carriage, and determine whether the carriage spacing meets the warning distance;

[0062] Specifically, step S2 includes the following steps:

[0063] S21, calculating the total length L4 of the carriages to be parked according to the number of carriages to be parked and the length of the carriages to be parked;

[0064] Among them, reference Figure 3 Since the track is one-way, shunting A needs to return after completing the shunting operation, so the car to be parked is located between shunting A and the existing car. In order to avoid collision between the car to be parked and the existing car, the total length L4 of the car to be parked needs to be calculated. According to the change length l of the car to be parked and the length a of the car to be parked, and the number n of the cars to be parked in this shunting operation is provided through the plan, the total length L4 of the car to be parked is calculated according to L4=a*n*l.

[0065] S22, determining the distance L2 between the existing carriage and the signal according to the position of the existing carriage and the position of the signal closest to the existing carriage;

[0066] Among them, after multiple shunting operations, there are existing carriages on the track. At this time, it is necessary to calculate the distance L2 between the existing carriages on the track and the corresponding signal.

[0067] S23, determining the distance L1 between the shunting train and the signal according to the real-time position of the shunting train and the position of the signal closest to the existing carriage;

[0068] Among them, after obtaining the real-time position of shunting train A and the position of the signal machine, the distance L1 between the signal machine X and shunting train A can be calculated, and the distance L1 will change in real time with the operation of the shunting train.

[0069] S24, calculating the distance between carriages L5 according to L5=L1-L4-L3-L2;

[0070] Among them, since the position of the existing car is close to one end of the signal, the end of the existing car away from the signal is the position where there is a risk of collision with the car to be parked. It is necessary to determine the position of the end of the existing car close to the car to be parked based on the total length L3 of the existing car, and then the car spacing L5 between the end of the existing car close to the car to be parked and the end of the car to be parked close to the existing car can be calculated. The car spacing L5 is calculated by L5=L1-L4-L3-L2, and the calculation is convenient and simple.

[0071] S25, determine whether L5 meets the warning distance, if not, execute step S23 and step S24, if yes, execute step S3 and determine whether the difference between the two compartment distances L5 obtained in step S24 is 0, if yes, end, if not, execute step S23 and step S24;

[0072] Step S25 is specifically as follows:

[0073] Determine whether L5 satisfies L5>La. If so, L5 does not meet the warning distance, and execute steps S23 and S24; otherwise, L5 meets the warning distance, and execute step S3, determine whether the difference between the two compartment distances L5 obtained in step S24 is 0, if so, end, otherwise execute steps S23 and S24;

[0074] Wherein, La is the warning distance, La = 10 * the length of the carriage to be parked * the change length of the carriage to be parked;

[0075] Among them, after calculating the distance L5 between the car to be parked and the existing car, it is necessary to determine whether L5 meets the warning distance. When the warning distance is not met, there is no need for anti-collision warning. Then execute steps S23 and S24 to continue calculating L5 and re-judge. Since the shunting operation is gradually approaching the existing car, L5 gradually decreases until L5 meets the warning distance. It means that the distance between the car to be parked and the existing car is close, and an anti-collision warning is needed to remind the shunting driver to pay attention to collision avoidance. The reminder method can be through sound, light, text and other methods.

[0076] When L5 meets the warning distance, since the shunting car continues to move forward, the distance between the car to be parked and the existing car is still changing, so it is necessary to execute steps S23 and S24 in real time when performing anti-collision warning. After recalculating L5 in step S24, it is determined whether L5 meets the warning distance. Since L5 has always met the warning distance after the shunting car parks the car to be parked at the corresponding position, and there is no need for a warning at this time, when the size of L5 before and after the calculation and judgment is no change, it is considered that the car to be parked has stopped steadily, and the anti-collision warning is ended at this time. Thereafter, when L5 increases, the anti-collision warning will not be started or continued.

[0077] The warning distance can be selected as La, that is, when L5≤La, it means that L5 meets the anti-collision distance.

[0078] S3: When the distance between cars meets the warning distance, an anti-collision warning is performed, specifically:

[0079] S31, determine whether L5 satisfies Lb<L5≤La, if yes, perform a ten-vehicle collision warning, if no, execute step S32;

[0080] S32, determine whether L5 satisfies Lc<L5≤Lb, if yes, perform five-vehicle collision avoidance warning, if no, execute step S33;

[0081] S33, perform three-vehicle collision warning;

[0082] The anti-collision warning includes a ten-car anti-collision warning, a five-car anti-collision warning and a three-car anti-collision warning, and the warning distance includes a ten-car warning distance, a five-car warning distance and a three-car warning distance;

[0083] La is the warning distance for ten cars, Lb is the warning distance for five cars, Lb=5*length of the car to be parked*change length of the car to be parked, Lc is the warning distance for three cars, Lc=3*length of the car to be parked*change length of the car to be parked;

[0084] Among them, when L5 meets the warning distance, it is first determined whether L5 satisfies Lb<L5≤La. If so, it means that the distance between the to-be-parked carriage and the existing carriage is greater than the five-car distance but not greater than the ten-car distance. At this time, a ten-car anti-collision warning is performed until L5 satisfies L5≤Lb. At this time, step S32 is executed, that is, the current L5 does not meet the conditions of the ten-car anti-collision warning and the ten-car anti-collision warning is not executed; when executing step S32, it is also necessary to determine whether L5 satisfies Lc<L5≤Lb. If so, a five-car anti-collision warning is performed. Otherwise, it means L5≤Lc. At this time, step S33 needs to be executed. When executing step S33, a three-car anti-collision warning is directly executed. At this time, the shunting driver stops after receiving the three-car anti-collision warning reminder to avoid collision and complete the shunting operation safely; the subsequently calculated L5 size remains unchanged. At this time, the step S25 is executed and the anti-collision warning is ended, and the anti-collision warning reminder in the shunting operation is completed.
