The information receiving work performed by the interface layer of the first layer comprises reading stage plan information from the stage plan, reading dictionary data such as train information, a station yard logic topological graph and a line code table from the dictionary data, reading current vehicle distribution information from a current vehicle system, acquiring historical operation information from historical data of operation, and completing the stage plan by supplementing the dictionary data, the current vehicle system and the historical data of the operation.

Wherein the train condition of the phase planning reaction yard within 3-5 hours in the future is shown in table 1, for example:

the phase plan reflects 18: 09-23: 25 future 5-hour 16-minute plans of 21119 trains in the station yard and 5-hour 23-minute plans of 21112 trains in the future 19: 24-00: 47, and specifically comprises the following steps:

The planning station representation service receives the stage planning information, dictionary data, current vehicle system information and historical data information, and generates the state change of each device represented by the station by calculation. The calculation operation of the planned station yard representation service is mainly to generate the states of various devices according to the delay amount of signal devices and the movement positions of locomotives, for example, 21119 times a train arrives at an departure station at 18:09 minutes, the train should be sent out from an adjacent station at 18:00, the system selects a short path with small interference according to the adjacent station of the train and 3 tracks of a receiving station track of the station (routing is one of the calculation of a computer), and the devices required by the path are locked (route handling) at about 18:00 minutes, the signal machine is opened, and the 21119 train is waited for entering the station. When the train arrives at the station and begins to occupy the equipment of the station, the corresponding equipment is occupied, cleared, unlocked and changed in state, which is about 18:05 minutes.

Fig. 3 shows an operational workflow diagram of a planned yard representation service, whereby the planned yard representation service includes decomposing a work unit, calculating resources required for a work, estimating start and end times of the work, calculating a locomotive start-up speed, an operation speed and an end speed and a locomotive displacement, deducing equipment status changes during the work, collating the existing train changes, synthesizing data change packages.

The calculation process of the planned station yard representation service comprises the following steps:

(1) disassembling operation unit

After the slave phase plan is supplemented according to station resources, the motion characteristics decompose the phase plan according to the busy characteristics of different operations in the phase plan, and the phase plan is decomposed into a plurality of operation units. The line occupation characteristic is the occupation position information of the current track of the train, and the movement characteristic comprises the following steps: an acceleration mode, a uniform velocity mode, and a deceleration mode. For example, operations at a marshalling station include operation operations, locomotive operations, and vehicle operations; the operation work can be divided into a train arrival work, a train disassembly work, a train formation work and a train departure work according to the busy characteristic and the motion characteristic of the operation work. And the train disassembly operation can be decomposed into a hump operation unit and a sliding operation unit again, specifically, the hump operation unit comprises a pushing part and a peak position, the sliding part of the sliding operation unit is arranged behind the peak position, the pushing part comprises an arrival field and a pushing wire, the train is pushed to a capping through the pushing wire, the train is disassembled at the capping, the sliding wire of the inflow part is arranged after the disassembly, and the train enters a shunting yard of the sliding part through the sliding wire. The original goods train firstly enters an arrival yard, after train inspection and air-blowing operation are completed, the shunting car receives an instruction and then drives the goods train to the hump direction in a backward pushing mode at the tail part of the goods train, at the moment, a hump annunciator is a green light, a hump worker starts to unhook the goods train according to the unhooking section number displayed on an LED display screen, the train is pushed to the peak top position to be unhooked, the unhooking truck chassis downwards accelerates to be fed with a slide-releasing line by inertia, and the goods train enters a grouping yard after being released by the slide-releasing line. The train enters a marshalling station to carry out train marshalling operation.

The train formation is divided into two operation units of vehicle connection and vehicle carrying running. Specifically, the bottom of the truck after being unhooked is accelerated downwards by inertia to enter a marshalling yard, a braking system is arranged on a track of the marshalling yard, and a dispatcher operates the braking system to enable the bottom of the truck sliding to the marshalling yard to move forwards at a certain speed and hang the truck on a vehicle stopped on the marshalling yard. When the train bottom of one of the trains is marshalled, i.e. a new train of goods is formed as required, the shunting machine can transport the train to the departure place. After the train is hung on the lead locomotive, the train drives to the destination station according to the signal of the station signal machine.

(2) Computing resources required for a job

And calculating the occupied resources required by the train number in the phase plan aiming at different operation units. The method specifically comprises the steps of occupying positions and occupied time of the station tracks of train numbers arriving at the station, occupying conditions of trains on push lines, occupying conditions of capping resources of humps, occupying conditions of trains on sliding lines and occupying information of the station tracks of the shunting yard in the phase plan. For example, it is calculated that 21119 times of train arrival operation of a train needs one track of an arrival yard, 21119 times of train disassembly operation needs one push line and one slide line, 21119 times of train marshalling operation needs two marshalling tracks, 21119 times of train departure operation needs one track, and 21119 times of train needs a track with a length of 100m on the marshalling yard for marshalling departure.

(3) Estimating start and end times of jobs

The start and end times of each unit of the job are estimated based on the history data. For example, the time of 21119 train inspection and wind pulling operations is estimated according to historical data, wherein the time of the operation reaching the train inspection is 30 minutes, and the wind pulling operation needs 10 minutes, namely 21119 trains reach and access to the departure yard No. 3 line at 18:09 and are stably stopped, and the train inspection work is completed at 18: 40; 21119 wind power of the train is taken as 10 minutes; 21119 trains enter the push line of the push part at 19:10, and start hump disassembly work when 21119 train heads pass through the crest at 19:30, the train heads are completely disassembled from the first carriage at 20:00, and enter a pay-off line; 21119 times of train shunting return at 21:40, and 21119 times of train marshalling and coupling at 22: 00; at time 21119, the train consist is completed and pulled out; the train is started 21119 times at 22: 40-23: 10, and the train is started 21119 times at 23: 35.

(4) Calculating the starting speed, running speed and stopping speed of the locomotive and the displacement of the locomotive

The starting speed, running speed and stopping speed of the train and the locomotive displacement are obtained by searching historical data provided in dictionary data according to the current traction force of the train and the self weight of the train, specifically, according to the number of carriages of the train, each sectionThe method comprises the steps of obtaining the dead weight of a current whole train through statistical calculation according to the actual load capacity of a carriage, obtaining the traction force of the train according to the model configuration of the train, obtaining the motion resistance and the static resistance of the train under different operations through historical data, obtaining the acceleration curve of a locomotive through real-time calculation, and measuring the train position of the train at each instant time point in real time according to the operation distance and the operation time of the train. For example, the weight of the head of a 21119-time train is calculated to be 120 tons, the weight of each carriage is 20 tons, the load is 60 tons, and 50 carriages are calculated, the self weight of the 21119-time train is calculated to be 120+ (20+60) × 50-4120 tons, wherein the 21119-time train is a rolling shaft bearing truck, and the train resistance formula of the national railway department to freight trains is as follows: 0.92+0.0048v +0.000125v²In units of newtons/kilonewtons (N/kN), where v is the velocity in units of kilometers/hour. The first of these three sets of numbers, "0.92", is a calculated constant of resistance for the rolling axle load-bearing truck, the second set of constants, "0.0048", is a calculated constant related to the mechanical resistance of the vehicle, and the third set of constants, "0.000125", is a calculated constant related to the aerodynamic (air) resistance of the vehicle. And calculating a train acceleration curve according to the traction force and the dead weight of the train and the movement resistance and the static resistance obtained by historical data to obtain the position of the locomotive on the station yard in each time period after the locomotive moves.

It should be noted that the locomotive has a speed limit required by railway technical regulations at each operating speed, for example, the running speed of the locomotive in the station does not exceed 40KM/h, and at this time, the calculated operating speed usually takes an upper limit of 40 KM/h. The starting speed is calculated from the tractive force of the locomotive, the resistance force, the curvature radius of the equipment, the gradient and the like, but in practice there is a limit value in view of the stability and safety of the cargo, i.e. the acceleration cannot exceed a limit value. Wherein the terminated acceleration and the initiated acceleration are similar.

Just because there is the maximum acceleration limit, the system can obtain its locomotive in every position probably acceleration from actual historical data, further improves calculated result and actual laminating degree.

(5) Deducing equipment state changes during operation

And calculating the equipment state change on the station yard according to the position of the locomotive, the length of the train and the length of the station track for running the train. And (4) determining the change of the equipment in the working process according to the estimated starting time and the ending time of the train in each working process in the step (3) and the position change information of the train after each working process is started, which is calculated in the step (4). For example, according to the estimation in the step (3), 21119 times of complete train uncoupling at 18:40 are known, and the train enters the humping line, according to the calculation in the step (4), 21119 times of constant-speed train humping on the humping line are known, and the real-time position information of the train on the humping line 21119 times can be calculated.

(6) Changes of finishing vehicle

And calculating the current train change on the station yard according to the operation plan and the train length. Illustratively, 3 vehicles stay in the No. 3 strand track of the current departure yard, 5 vehicles stay in the No. 4 strand track of the departure yard, if a single plan is made, the vehicles in the No. 3 strand track of the departure yard are sent to the No. 4 strand track of the departure yard, and the vehicles in the No. 4 strand track of the departure yard are 8 vehicles through calculation; if a single plan is made, 7 vehicles arriving at the No. 4 line track of the departure yard are sent to the track. Through the present vehicle deduction, the stop vehicle on each track can be accurately obtained, and then the system can accurately obtain whether the station track equipment is occupied or not.

(7) Synthesizing data change packets

And (5) combining the information of the two steps (5) and (6) into a data packet which changes along with time.

After the planned battlefield representation service of the second layer is executed, the result of the planned battlefield representation of the second layer is displayed through the display layer of the third layer, and whether the result of the phase planning is reasonable or not can be visually displayed.

For example, at 18:09 a train arrives and connects to departure 3 line 21119 times, and at 23:35 a train departs 21119 times. The 21119 trains adopt C62 series open wagons, the number of the wagons is 50, the length of a train compartment of the C62 series train is 12.5m, and the total length of the 21119 trains is 637.5 m. According to calculation, 21119 times of trains need to arrive at one station track of a yard within the time period of 18: 09-23: 35, 21119 times of train disassembly operation needs one push line and one slide release line, 21119 times of train marshalling operation needs two marshalling station tracks, and 21119 times of train departure operation needs one station track. The specific display results for 21119 trains are as follows:
