Description

Automatic generation method for passenger locomotive LKJ data reloading plan

Technical Field

The invention relates to the field of LKJ data reloading management, in particular to a method for automatically generating a reloading plan when a passenger locomotive reloads LKJ data.

Background

The locomotive is a self-propelled vehicle which pulls or pushes a railway vehicle to run and does not load business load per se, and is commonly called a locomotive. A passenger locomotive is a locomotive in which a passenger mission is being undertaken. The running time of the passenger locomotive is complicated to calculate. And (3) calculating the specific reloading place and reloading time of each LKJ vehicle-mounted data according to the time of each passenger locomotive leaving the garage and the time of reaching the construction place by combining the turning back condition of the locomotive. The working efficiency is low, the problems of mistaken replacement and missed replacement are easy to occur, and the liability accidents of the passenger locomotive and the motor train unit are caused. The electric staff is difficult to change the equipment and control in the foreign warehouse. The passenger transport reloading is more, the passenger transport locomotive cannot be reloaded according to the unified time, the reloading progress is difficult to track, and the driving safety is seriously threatened.

When the LKJ data needs to be reloaded, the reloading management personnel need to search the train number passing through the changing point according to the changing point of the data, and if the train number is found to be turned back by other train numbers, the train number before turning back needs to be found, and the train number is calculated out of the warehouse in sequence; and then according to the effective time of the change point data, judging whether new data is needed when the change point is passed for the first time, namely whether reloading is needed before ex-warehouse so as to carry out reloading arrangement. The manual calculation needs to be performed for each train number, and the flow executed by each train number is shown in fig. 1.

In the above duplication calculation process, all the train numbers need to be searched, and nearly 200 passenger train numbers are owned by the railway bureau of the least call and the most extreme according to the survey; and the turning back condition of each vehicle is also required to be considered, so that the manual workload is large, errors are very easy to occur, the driving safety is influenced, and the life and property safety of passengers is caused.

Therefore, a method for automatically generating a reloading plan needs to be researched. The working efficiency of basic line data reloading personnel is improved, the labor cost is reduced, and accidents are reduced.

Detailed Description

The present invention will be described in detail with reference to specific embodiments. The following examples will assist the person skilled in the art in further understanding the present implementation but are not intended to limit the invention in any way. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present solution, which falls within the scope of protection of the present solution.

The general terms and their definitions in the field of monitoring the operation of a plurality of trains referred to in the solution of the invention are given in the following glossary.

Glossary

The reloading plan provided by the invention mainly ensures that the line data description is changed when the railway line construction is carried out, and when LKJ is loaded with line data and passes through a construction site (namely, a data change point), the LKJ cannot be loaded with old data and pass through a construction site which is effective already, and cannot be loaded with new data and pass through a change point which is not effective yet. That is, it is ensured that the line data loaded on the LKJ matches the current (data valid) situation when the LKJ passes through the data change point.

The data change point referred to in the present invention means: the location where the description of the route data changes due to the route construction or the like. For example, the speed limit of the section after the station A is out of the station is 80Km/h, and the speed limit of the section after the station A is out of the station needs to be adjusted to 40Km/h for construction reasons. Then the "outbound zone of a" is the data change point.

The data effective time mentioned in the present invention refers to: the point in time at which the data at the data change point becomes effective. For example, if the section after the a station is out of the station starts construction at 30 am 6 am on 1 st in 2019, month 9, the data effective time is "30 am 6 am on 1 st in 2019. That is, the segment speed limit after the outbound A before the data validation time is 80Km/h, and the segment speed limit after the outbound A after the data validation time is 40 Km/h.

The ex-warehouse time mentioned in the invention refers to: the time the locomotive comes out of the garage. For example, when locomotive HXD3D-5002 is in the marshal yard and needs to be taken out of the marshal at 20 am on 1 st day on 9 months in 2019 to perform a trailer mission, then locomotive HXD3D-5002 is taken out of the marshal yard at 20 am on 1 st day on 9 months in 2019.

Fig. 2 is a flowchart of an automatic generation method of a reloading plan according to the present invention, and the following specifically describes main steps of the automatic generation method of an LKJ data reloading plan according to the present invention:

1) determining data change points and times

And finding a data change point on the railway line according to the notification of the reloading task, and determining the effective time of the good data. And arranging the station information of each route according to the route.

2) Arrangement of train number and turn-back

The form in the form of train number table is arranged according to the running condition of the passenger locomotive (namely, the route passed by each train number arranged by the transportation department, the station information of each line is arranged according to the line name) and the information such as whether the locomotive (namely, the locomotive) in charge needs to be replaced by each train number.

① if a locomotive is changed during operation, the current train is changed into two trains, for example, T56 from Xian to Beijing via Zheng requires changing the locomotive at Zheng state station, then the original T56 is changed into two trains, namely T56-1 and T56-2, ② if there are two trains, the two trains are not put in storage after the first train arrives, but directly turned back into other trains, then the two trains need to be connected in series, for example, K217 is directly turned back into K218 without putting in storage at the head of the train, and then K217 and K218 are treated as one train, namely K217-K218.

3) Calculation process of reloading plan (determining reloading opportunity according to warehouse-out time and data effective time)

①, for the locomotive which comes out of the warehouse after the data is valid, namely the valid time of the data is after the warehouse-out time (for example, the valid time of the data is 30 minutes at 6 am on 1 st in 2019, 9.1.a.2019, and the warehouse-out time is 30 minutes at 10 am on 1 st in 2019), when the locomotive passes through the change point, the data is necessarily valid, the locomotive should be controlled by adopting new data, and the data is reloaded at the warehouse-out time, so the data is reloaded before the warehouse-out is regulated.

② for the locomotives whose data is valid after leaving warehouse, the train numbers which do not pass through the change point are divided into two types according to whether the train numbers are passed through the change point, theoretically, the train numbers which do not pass through the change point are not affected by the data change, but considering the convenient management (the data versions on all the locomotives are consistent after the completion of one reloading task, namely all the locomotives are reloaded), the locomotives of this type can be reloaded before leaving warehouse.

③ for the train passing the data change point, the locomotive acting as the train needs to be divided into the passage before the data is effective and the passage after the data is effective again according to the data effective time passing the data change point.

④, for the number of cars passing after the data becomes valid, the locomotive in charge can be reloaded before the car is delivered.

⑤, for the train number passing before the data is effective, the locomotive in charge (the reloading is not allowed when the train is delivered out of the warehouse this time) until the train is delivered in the warehouse and does not pass the reloading point again, and the steps are repeated until the reloading is available.

⑥ for the train number passing before the data becomes effective, the locomotive in charge passes the changing point again (or multiple times) before entering the garage again, if the time of passing the changing point for the second time (and later times) is the time of the data becoming effective, then the locomotive does not have the condition of changing the device in the garage (if the data is changed before the garage is taken out, the data loaded when the locomotive passes the data changing point for the first time is not consistent with the line condition, if the data is not changed before the garage is taken out, the vehicle-mounted data when the locomotive passes the data changing point for the second time is not consistent with the line condition), and the locomotive needs to be prompted to be changed on line or be processed in emergency.

When the road bureau determines to change the loading, the version of the new data, the change point in the new data and the effective time of the change point are only needed to be input into the computer system, and the loading change plan can be automatically generated according to the method.

Example one

Next, a method of generating an LKJ data reloading plan according to the present invention will be described by taking Z317 times from beijing to a header as an example.

1) Arranging station information

The station information of each line is arranged according to the line (line name), and the arranged format is 'station information table'. The core content of the station information table is shown in fig. 3.

2) Arranging time of train number and turn-back information

The 'train number table' and the 'return information table' are arranged according to information such as a train operation chart and whether a locomotive serving as the train number is changed.

Wherein, the 'train number table' collects all train numbers under the road bureau, a table is created for each train number, and the table content is a time point plate when the train number passes through all stations. The "train order table" is shown in FIG. 4.

The 'turning back information table' is arranged and sorted out according to the running chart of the road bureau to describe the continuing situation of each train number. The format of the "foldback information table" is shown in FIG. 5.

For example, if the locomotive is sent to the head of a car from Beijing for Z317 times, the locomotive is exchanged in a calling and garage and then sent to the head of the car when the route is called very often, ① is sent out of the garage to the calling and warehousing from the Beijing, ② is sent out of the garage to the head of the car from the calling and warehousing, and if the locomotive is not warehoused after Z183 times of calling and warehousing out of the garage reaches the river station and is sent to the head of the car from the river for 0Z6542 times, ① Z183 times of folding to 0Z542 from the calling and warehousing to the river station, and ② 0Z542 times of sending to the head of the car from the river.

3) Reloading flow algorithm

①, the train numbers are connected in series according to the warehouse entry and the warehouse exit, namely, the train numbers are arranged into one train from the warehouse exit to the warehouse entry, for example, Z183 times are directly turned back to 0Z6542 without warehousing in a river, and the system treats Z183 and 0Z6542 as one train, namely Z183-0Z 6542.

Meanwhile, the train number of multi-warehousing is divided into a plurality of train processes, for example, Z317 times sent to the packet header by Beijing, and when the train is called and warehoused (namely, the locomotive is replaced), the system divides Z317 into Z317(1) and Z17(2), wherein Z317(1) represents that the train is called and is honored from Beijing, and Z317(2) represents that the train is called and is honored from the packet header.

② for the passenger car whose data is valid after leaving the warehouse, the sorted cars are divided into two types of passing before and after the data is valid according to the valid time of the change point data.

③, for the data passing after the data is effective, calculating backwards whether the data passes through the data change point before entering the warehouse, if the data passes through the prompt, urgent reloading (on-line reloading) or special treatment is needed, if the data does not pass through the data change point, the data is not processed.

④ for passing before effective, it is calculated to see if the data change point passes before delivery, if it is indicated that urgent reloading (on-line reloading) or special treatment is needed, if it does not pass, then reloading is carried out before delivery.

⑤, for the passenger car with the data valid before the passenger car is delivered, arranging to change the data of the passenger car before the passenger car is delivered.

The scheme of the invention has the following technical advantages:

① according to the invention, the manual arrangement of the reloading plan is converted into the automatic arrangement of the reloading plan by a computer, thereby reducing the error probability in the complicated calculation process and improving the working efficiency.

② the method of the invention has the advantages of computer operation, reduced work intensity, and no manpower.

③ the invention has the advantages of effectively reducing the probability of data mischange and neglected data change, effectively ensuring the safety of LKJ data and improving the efficiency of reloading plan arrangement after a large amount of verification.

The above description is only a preferred embodiment of the present novel scheme, and is not intended to limit the scope of the present novel scheme. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the new scheme shall be included in the protection scope of the new scheme.
