Description

Enterprise railway plane shunting intelligent tracking system and its working method

technical field

The invention belongs to the technical field of railway intelligent shunting.

Background technique

As the main artery of the national economy, the country's important infrastructure and popular means of transportation, the railway plays an important role in the transportation of goods for coal mining enterprises. However, before the train departs, a certain marshalling must be carried out at the station, and vehicles with the same cargo, the same direction, and other relevant special requirements should be marshaled into a train. The failure of the trains to be sorted out in time has brought about many problems such as train marshalling errors, chaotic management of existing trains, etc., resulting in the status quo of too many people, low efficiency, and unsafety.

At present, the national railways mainly use "plane shunting" and "hump shunting" in terms of train formation. "Plane shunting" refers to all purposeful movement of locomotives and vehicles on a relatively horizontal station; "hump shunting" means pushing the entire train to the top of the peak, and using the slope to make the trains slip one by one to different lanes to connect The clerk is responsible for following the car, picking up the car, lifting the hook, and completing the task of marshalling. Among them, "plane shunting" means that station attendants and shunting personnel (including locomotive drivers and shunting personnel) confirm the progress of shunting operations through paper shunting plan worksheets, track circuits, and wireless plane shunting equipment. , and arrange the next hook-tuning car approach. Since the station attendants, drivers, and shunters only communicate with each other through wireless intercom equipment, there is a lack of effective mutual safety control among them. There are often problems such as hanging the wrong car, wrong arrangement of routes, and even escalating traffic signals. , crowded turnouts and other safety accidents.

Enterprise railways have industry characteristics such as no separation of shunting operations and a large amount of shunting operations, and generally adopt the plane shunting operation method. The application systems such as microcomputer interlocking, centralized dispatching, and locomotive signals are scattered and isolated, and the data sharing ability is poor. However, the safety prevention of shunting operations is still at the stage of human control, which makes the intrinsic safety guarantee level of enterprise railways still at a low level.

Figure 4 is a schematic diagram of the application of the above-mentioned system at the railway transportation site in the Jibei mining area of Zibo Mining. There are three station freight yards on the site for unified command and dispatch. According to Figure 4, the implementation of a certain batch of shunting operation plans on the site is described as follows:

If the following batch of shunting operations are to be carried out at Dongzhuang Station, the plan is:

The first tick: locomotive 2 shareholders out;

The second tick: 4 shares + 15 (vehicle);

The third hook: 3 shares - 3 (vehicles);

The fourth hook: 4 shares - 6 (vehicles);

The fifth tick: 8 shares - 2 (vehicles);

Sixth hook: 4 shares - 1 (vehicle);

The seventh hook: 3 shares - 2 (vehicles);

The eighth hook: 4 shares - 1 (vehicle);

The ninth tick: 2 shares of locomotives are on standby.

Specific work method:

The first step: preparation work; the station attendant prepares the above-mentioned shunting plan work sheet for the trains that need to be organized according to the dispatching plan, and calls the locomotive through the wireless interphone;

The second step: the locomotive starts. After the driver hears the call from the station attendant, he starts the engine in time, and the on-board equipment automatically transmits the GPS coordinates, speed, handle position, and rotational speed of the locomotive to the server of the ground machine wirelessly in real time;

Step 3: Transmit the shunting operation plan; the station attendant sends the above shunting operation plan to the on-board equipment of the locomotive by using the operation platform and radio station of the ground machine;

Step 4: Confirm the work plan. After seeing the shunting operation plan displayed on the on-board terminal, the driver repeats the operation content to the station attendant through the wireless intercom. After both parties confirm that it is correct, the driver starts to move the car;

Step 5: Confirm the forward path of the motor vehicle; the locomotive transmits the industrial and mining data of GPS coordinates, speed, speed, and handle position to the ground machine. After confirmation, the server of the ground machine will receive the current operation plan, track occupancy, and signal opening Information such as the status, distance from the locomotive to the signal machine, etc. are redisplayed to the on-board terminal of the locomotive. At this time, the driver sees that the on-board terminal shows that everything is normal, and "the first tick in the shunting operation form: locomotive 2 shareholders exit" turns into a green light strip, and the current 2-share road east signal where the locomotive stays is repeated as the ground signal. White shunting signal", indicating that the shunting plan, route conditions, and system operation are all normal, and the locomotive can go out from the 2nd shareholder. At the same time, the "4 units + 15 (vehicles)" on the terminal of the station attendant and the vehicle terminal turned into a yellow light band, indicating the next operation plan.

Step 6: Locomotive running; during the running of the locomotive, the server of the ground machine confirms the section and milepost where the locomotive is located through differential GPS coordinates and track voltage, and feeds back this information to the display terminal of the station attendant and the on-board terminal in real time; When the driver hears "danger of overspeeding or danger of crossing the signal" from the on-board terminal during the operation of the locomotive, it means that the speed of the locomotive is too high or the ground signal is not open. The driver should slow down or stop immediately, otherwise, the locomotive will stop automatically.

Step 7: The first hook operation is completed, that is, after the locomotive comes out from the 2nd stock and stops, the shunting operation plan sheet "locomotive 2 stock" on the terminal on duty at the station and the vehicle terminal turns into a red light belt, "4 stock + 15 (vehicle)" turns into a yellow band.

Step 8: Start the "No. 2 hook operation". After the above-mentioned first hook operation is completed, the on-duty officer arranges the second hook operation route according to the information prompted by the shunting operation plan sheet and the light belt, and the on-board terminal displays the shunting signal entering the 4 strands in real time;

Step 9: The driver enters the 4 trailers according to the shunting signal displayed on the vehicle terminal and the completion progress of the plan sheet. At this time, the shunting operation plan sheet of the terminal on duty at the station and the vehicle-mounted terminal "locomotive 2 shareholders out" turns into a red light belt, "4 shares + 15 (vehicles)" turns into a green light belt, "3 shares - 3 (vehicles) )" turns into a yellow light band, indicating that the first hook operation has been completed, the second hook operation is being executed, and the next hook preparation operation is the third tick;

Step 10: Pull out the locomotive trailer. When the driver takes 4 strands of 15 vehicles out according to the command of the on-site shunting personnel, he repeats the above-mentioned "step 5" to "step 9" to confirm the plan sheet, signal, route, etc., and then completes the second step. Tick the job content. What is different in the operation process of the seventh step here is the change of the current vehicle at the station attendant terminal and the system prompt of the on-board terminal: one is the station attendant terminal, when the locomotive leaves with 15 cars from 4 shares The terminal of the station attendant shows that 4 strands have decreased by 15 vehicles, and the station attendant is reminded in real time that the number of locomotives is consistent with the plan. Otherwise, the station attendant should contact the on-site shunter in time to confirm the number of locomotives; The second is the vehicle-mounted terminal. When the locomotive takes 15 vehicles out of the 4th section, if the vehicle-mounted system issues an alarm prompt of "the number of vehicles is wrong", it means that the number of vehicles brought is inconsistent with the plan, and the driver should contact the station in time. There is no alarm prompt, indicating that the number of vehicles is correct.

Step 11: Start the 3rd hook operation. Follow the "eighth step", "ninth step" and "tenth step" procedures in order to carry out the third hook operation. What is different at this time is the existing car sorting part of the terminal on duty at the station. When the locomotive brought 15 cars into the 3rd stock, the 3rd stock immediately increased by 15 cars. )" After the hook operation, the number of existing trains increased from 15 to 3 for the 3 shares, indicating that the on-site operation is consistent with the shunting plan;

After the rest of this batch of shunting operations are completed in accordance with the procedures of "step five", ..., and "step eleven", first, the shunting operation plan sheets of the station attendants and vehicle terminals all turn into red bands , indicating that the shunting operation has been completed; second, the station attendant can confirm in time whether the distribution of existing trains in the entire station is consistent with the plan issued by the dispatcher, which provides a detailed basis for the marshalling of the next train.

With reference to the operation program judgment flow chart shown in Fig. 3, the detailed working method of the above-mentioned railway level shunting intelligent tracking system will be described again.
