Description

Technical Field

[0001] The invention relates to the technical field of railway operation monitoring, and in particular to a railway dedicated line shunting operation monitoring system. Background Art

[0002] A dedicated line refers to a railway line that is connected to the national railway and managed by an off-site enterprise or institution. It is an important facility to solve the "first kilometer" and "last kilometer" of railway transportation. The dedicated line, which is led by the station (assistant) dispatcher of the marshalling yard and is responsible for shunting operations by the national railway station shunting team, includes not only dedicated lines directly connected to the marshalling yard, but also dedicated lines connected to intermediate stations under the jurisdiction of the marshalling yard. Compared with shunting operations within the station, there are many problems with dedicated line shunting operations:

[0003] (1) There are many hidden dangers in shunting. The dedicated line is usually more than 1 km away from the station, with long sections, many curves, complex sections and poor observation conditions. Most shunting is done by push shunting, which requires checking whether the level crossing is closed, whether the enterprise gate is open, and whether there are people or foreign objects intruding on the operating line. However, the shoulders are generally narrow, which is not convenient for the shunting team to walk, and the walking inspection time is long. There are many return shunting routes, and the switches are frequently turned. The direction of the switch opening and whether the point rail is close to each other must be manually checked by the shunting team, and squeezed switches and derailment occur from time to time.

[0004] (2) The shunting equipment is in poor condition. Without information equipment, changes to the shunting operation plan can only be made by voice notification on the horizontal shunting handheld device, which is easy to forget; without centralized interlocking equipment, the switch indication and switch close-fitting can only be done by sight and handwriting; iron shoes and manual brakes are used to prevent slipping, and the anti-slip indication can only be done by handwriting; the lighting conditions at night are poor, and it is difficult to confirm the status of gates, crossings, lines, and vehicles, and it is difficult to lead the vehicle and look out when advancing shunting; the shunting team has no means of reporting shunting points, and can only notify the shunting district chief by voice after a batch of operations are completed, and the shunting district chief manually enters the system, which results in reporting errors.

[0005] (3) Shunting management is difficult. The station video surveillance system cannot be deployed to the dedicated line that belongs to the assets of off-road enterprises. Station dispatchers, freight dispatchers, and shunting district chiefs cannot dynamically grasp the equipment and operation status of the dedicated line. The crossing indication, gate indication, line intrusion, turnout indication, anti-slip indication, and line storage status of the dedicated line can only be marked on the line occupancy board after the shunting team returns to the station; the joint control process such as simple testing, test pulling, and entry and exit can only be completed through voice intercom. Problem analysis can only be done by playing back the call recording and reviewing the video of the operation recorder, making it difficult to obtain evidence.

[0006] Although shunting operations on special lines are not the mainstream of shunting operations in marshalling yards, they are in the blind spot of operation monitoring, and the cost of daily safety management is very high; and shunting on special lines takes a long time for shunting, which has a great impact on whether the stop time index of the marshalling yard can be fulfilled. Not only marshalling yards have the need to realize the monitoring of shunting operations on special lines, but also section stations and train depots have the need to realize the monitoring of shunting operations on special lines. In the past three years, many railway bureaus and group companies have been carrying out relevant scientific research projects, and more than ten companies inside and outside the railway have participated in it. The future market prospects of products are very broad.

[0007] In order to solve the above-mentioned dedicated line shunting problem, there are currently two technical routes in China:

[0008] The first is a technical route based on solving problems with electrical equipment. By installing computer interlocking systems, wireless shunting locomotive signals and monitoring systems on the dedicated line, the problems of turnout, route control and shunting operation safety protection are solved; by adding vehicle number recognition equipment, wheel sensors, transponders and other ground sensors, an electronic bus board for the dedicated line is developed, and the gates, crossings, line storage and anti-slip marks of the dedicated line are included in the integrated automation system of the marshalling yard for management. The advantage of this technical route is that it is based on mature electrical systems and equipment, the technical research and development is not difficult, and it is easy to implement the project; the disadvantage is that the test pulling, simple test, access line joint control and other operation projects of the outdoor shunting group cannot be included in the electrical system function from the perspective of professional management, and the needs of dedicated line shunting are not fully met. At the same time, the equipment procurement and project investment are large, and the electrical department is not willing to manage the dedicated line equipment. Up to now, the solution based on this technical route is still in the research stage and has not been actually applied in the marshalling yard.

[0009] The second is a technical route to solve the problem based on vehicle equipment. By equipping the shunting group with a new handheld terminal, which has the functions of video recording, indoor and outdoor voice calls, and file transfer, the shunting operation notice and shunting operation report can be checked manually on the handheld terminal; by adding ground equipment such as cameras and laser radars, image recognition technology is used to detect gates, crossings, hand-operated turnouts, line intrusion, anti-slip and withdrawal status, and equipment status display terminals are added for station dispatchers, freight dispatchers, and shunting district chiefs. The advantage of this technical route is that special equipment has been developed for the operation scenario of dedicated line shunting, which can cover the main pain points of dedicated line shunting and has moderate investment; the disadvantage is that it is not combined with the flat shunting light display system, and there is no protection for the shunting motor wheel. Checking and reporting shunting related information requires adding a set of handheld terminals to the shunting group, which increases the complexity of operation. Up to now, the solution based on this technical route has only been tried in a small number of intermediate stations with a small amount of dedicated line shunting operations, and has not been actually applied and promoted in marshalling yards.

[0010] In view of this, the present invention is proposed. Summary of the invention

[0033] In order to more clearly demonstrate the technical solution and technical effects provided by the present invention, the system provided by the embodiment of the present invention is described in detail with reference to a specific embodiment below.

[0034] 1. Overall introduction of the system.

[0035] like Figure 2 The figure shows the overall structure of the system, which includes: flat shunting light display subsystem, non-centralized area shunting monitoring subsystem, shunting operation auxiliary subsystem, and connected to the marshalling yard integrated automation system at the station. Among them, the flat shunting light display subsystem and shunting operation auxiliary subsystem are mobile business systems, which can be used in both centralized and non-centralized areas. The following introduces each subsystem separately.

[0036] 1. Flat adjustment of car light display subsystem.

[0037] like Figure 2 As shown, the flat adjustment vehicle light display subsystem includes: a flat adjustment zone manager station, a flat adjustment machine controller, a flat adjustment handheld device, a communication server and two communication interface machines; the flat adjustment machine controller, the flat adjustment handheld device, the first communication interface machine and the second communication interface machine communicate with each other using 400M radio; the second communication interface machine and the communication server, as well as the communication server and the flat adjustment zone manager station communicate through serial ports.

[0038] (1) Communication interface machine 1 (the first communication interface machine) is located in the enterprise monitoring room (within the dedicated line) and interfaces with the non-centralized area shunting monitoring subsystem to transmit the received relevant plan status information (for example, train entry and exit reporting points), relevant equipment status information (gate opening and closing conditions, etc.) and line status information (number of stored vehicles, vehicle numbers, vehicle types, etc.) to the communication server via the second communication interface machine (i.e., communication interface machine 2).

[0039] (2) The communication interface machine 2 is installed in the station machine room, and is connected to the communication server through the serial port, and is connected to the on-board host interface of the shunting operation auxiliary subsystem through the 400M radio method. The relevant equipment status information and shunting status information (target distance measurement, foreign object intrusion limit, train wind pressure value, simple test reporting point, test pulling reporting point, etc.) provided by the shunting operation auxiliary subsystem are fed back to the marshalling yard integrated automation system through the communication server, and the shunting operation notification form of the marshalling yard integrated automation system is fed back to the shunting operation auxiliary subsystem.

[0040] (3) The communication server is set up in the station machine room and is connected to the shunting area long table, shunting machine controller, shunting handheld device and the second communication interface device respectively; it is used to receive the shunting operation notification form issued by the integrated automation system of the marshaling yard and transmit it to the shunting machine controller and the shunting handheld device, feedback the manual reporting point (hook cancellation) of the shunting group to the integrated automation system of the marshaling yard, and forward the relevant plan status information, relevant equipment status information and line status information provided by the non-centralized area shunting monitoring subsystem and the relevant equipment status information and shunting machine status information provided by the shunting operation auxiliary subsystem.

[0041] (4) The horizontal shunting machine controller is installed on the shunting machine and connected to the LKJ. It is used to provide shunting voice intercom, single-screen display of shunting operation notification and horizontal shunting light display functions; according to the horizontal shunting signal sent by the shunting operation auxiliary subsystem, the shunting machine adopts corresponding control measures (for example, controlling the LKJ to take deceleration, unloading, conventional braking, emergency braking, etc.); and according to whether the entry permission and exit permission of the marshaling yard integrated automation system are received, the horizontal shunting start and propulsion signal are controlled and restricted.

[0042] (5) The horizontal shunting handheld device is a standard configuration for shunting team operators (for example, one for each person). It is used for shunting voice intercom and issuing horizontal shunting signals. It can also display shunting operation notices on the screen, as well as report points for anti-skidding and hook plan cancellation.

[0043] (6) The station of the horizontal dispatch area is located at the assistant dispatcher (assistant dispatcher) and the assistant duty officer, and is connected to the communication server for voice calls and responses on the ground and in the vehicle, monitoring and recording horizontal dispatch voice intercom information, and monitoring and recording horizontal dispatch signaling.

[0044] 2. Non-centralized area shunting monitoring subsystem.

[0045] like Figure 2 As shown, the non-centralized area shunting monitoring subsystem includes: enterprise terminals, enterprise servers, crossing guardrail sensors, gate door sensors, hand-operated switch sensors, vehicle number recognition equipment and wheel sensors; the enterprise server communicates with each sensor and vehicle number recognition equipment using LoRa; the enterprise terminal and the enterprise server communicate via Ethernet LAN.

[0046] (1) Enterprise terminals are used to provide enterprise freight specialists with a human-machine interface for line status, track storage, and manual marking of operations. Each enterprise has one set, which is installed in the enterprise monitoring room and can be equipped with an enterprise mobile terminal according to the needs of the enterprise.

[0047] (2) The enterprise server interfaces with the flat shunting light display subsystem to comprehensively process the perception information reported by each sensor and the car number recognition device, and automatically generates the shunting car entry and exit enterprise reporting points and track reporting points for shunting cars in combination with the shunting operation reporting points and the shunting car position information, and automatically updates the track storage car information, and finally obtains the relevant plan status information (for example, the train entry and exit line reporting points), relevant equipment status information (gate opening and closing status, etc.) and line status information (the number of stored cars, car number, car type, etc.). One enterprise server is set for each enterprise, which is set in the enterprise monitoring room (or the computer room provided by the enterprise).

[0048] (3) Crossing guardrail sensor, used to sense whether the section crossing guardrail is closed; one set is provided for each guardrail and can be battery-powered.

[0049] (4) Gate door sensor: used to sense whether the enterprise gate is open and whether the wind hook is locked. One set is set for each door leaf and can be powered by batteries.

[0050] (5) Manual switch sensor, used to sense whether the handle of the manual switch is in the fixed or reverse position, and whether the fixed or reverse point rail is tightly attached. One set can be provided for each set of manual switch, and can be powered by batteries.

[0051] (6) Vehicle number recognition equipment, used to scan the vehicle numbers of trucks entering and leaving the enterprise and record the time they have passed; one set can be installed for each enterprise, inside the enterprise gate, and the vehicle number recognition sensor can be powered by single-phase 220V 50Hz AC.

[0052] (7) Wheel sensors are installed in front of each turnout and at the entrance of each track to sense the number of axles passing through the turnout and entering and exiting the track and record the time it takes. For dead-end tracks, they are installed at one end of the train entering and exiting. For through tracks, wheel sensors are installed at both ends of the track. The wheel sensors can also be powered by batteries.

[0053] Preferably, the non-centralized area shunting monitoring subsystem may also reserve cargo space intrusion monitoring sensors, water level monitoring sensors, anti-slip monitoring sensors, protective sign monitoring sensors and mobile derailer monitoring sensors that are respectively communicated with the enterprise server.

[0054] Cargo space intrusion monitoring sensors are installed one set on each track with loading and unloading operations to detect whether there are piles of objects and equipment intruding on the track.

[0055] One water level monitoring sensor is installed in areas that are often flooded to detect whether there are flooded lines on rainy days.

[0056] Anti-slip monitoring sensors, one set is installed on each storage track, used to detect whether iron shoes, wheel stoppers or anti-slip sleepers are placed on the track, and whether the manual brake is tightened;

[0057] Guard sign monitoring sensor: one set is installed in each parking track with guard signs, which is used to detect whether the guard sign is erected or down;

[0058] Mobile derailer monitoring sensor, one set is installed on each storage track, to detect whether a mobile derailer is placed on the track.

[0059] 3. Shunting operation auxiliary subsystem.

[0060] like Figure 2 As shown, the shunting operation auxiliary subsystem includes: a car leader, a wind pressure device (not shown in the figure), a vehicle-mounted host, a vehicle-mounted terminal and a reflector. The car leader, the wind pressure device and the vehicle-mounted host communicate with each other using a 2.4GHz or 5.8GHz wireless frequency, and a 5G interface is reserved. The reflector is a passive device.

[0061] (1) The train leader provides positioning and perception during shunting operation. Specifically, each shunting group is equipped with two sets of train leaders, one set for the downstream end of the train and the other set for the upstream end of the train. When the shunting locomotive is operating alone, the two sets of train leaders are placed in front of and behind the shunting locomotive for forward and rearward perception. When the shunting locomotive is pushing a train, the train leader on one side of the train is placed outside the head truck of the train for forward perception, forward ranging and test pulling perception. When the shunting locomotive is pulling a train, the train leader on one side of the train is placed outside the rear truck of the train for rearward perception and rearward ranging.

[0062] (2) The air pressure sensor is used to sense the air pressure value. Each shunting group is equipped with one set. When the shunting train needs to connect the air duct, the air pressure sensor is installed at the air duct joint of the last freight car connected to the connection to sense the air pressure value.

[0063] (3) The vehicle-mounted host is used to centrally process the information sent back by the leader and the wind pressure sensor (forward vision perception, rear vision perception, distance measurement and positioning, test pull perception, and wind pressure perception information), send automatic horizontal shunting signals (including ten cars, five cars, three cars, one car, deceleration, connection, stop, emergency stop, and unlocking) to the horizontal shunting machine controller in the horizontal shunting light display subsystem, automatically generate relevant equipment status information (for example, line limit infringement), shunting machine status information (wind pressure value, simple test, test pull reporting point information, etc.), and report to the integrated automation system of the marshalling yard through the horizontal shunting machine controller.

[0064] (4) On-board terminal: Each shunting machine is equipped with one set, which is used to display real-time video of the front and rear of the train to the shunting master and driver, indicate the location and distance of intruding foreign objects, display the distance between the front end of the train and the target parking point, and provide a human-machine interface for simple testing, test pulling and anti-skidding reporting points.

[0065] (5) Reflectors: There are two types: fixed and mobile. Fixed reflectors are installed at wheel sensors or dead-end earth barriers, and are used by the train leader to sense the distance between the front end of the train and the wheel sensor or the dead-end earth barrier. The reflector installed at the wheel sensor is used to sense the distance from the wheel sensor after the train has stopped. The purpose is to provide the distance between the track-stopped vehicle and the wheel sensor for the next time the train is shunted into the line, and determine the "ten-car" position. When the distance between the track-stopped vehicle and the wheel sensor is less than "ten-car", the "ten-car" position should be moved forward to the corresponding switch reflector). Mobile reflectors are deployed at parking spots that need to be aligned with the cargo position, and are used by the train leader to sense the position of the aligned parking spots.

[0066] Based on the above introduction, the internal network of each subsystem is as follows:

[0067] (1) The flat shunting light display subsystem still uses the existing 400M radio channel for networking, and provides an additional independent 400M frequency point for data relay and forwarding between the non-centralized line monitoring subsystem, shunting operation auxiliary subsystem, and marshalling yard integrated automation system.

[0068] (2) The non-centralized area line monitoring subsystem uses LoRa independent networking.

[0069] (3) The shunting operation auxiliary subsystem uses 2.4GHz or 5.8GHz wireless frequency for communication (with a 5G interface reserved), with the shunting machine as the center, covering the front and rear ends of the train. Before accessing the 5G public network or 5G-R, visual information is only processed and displayed on the shunting machine and is not transmitted back to the room.

[0070] 2. The system's operating procedures.

[0071] In an embodiment of the present invention, the operation process of the above-mentioned system includes: shunting operation preparation, incoming shunting route contact and confirmation, incoming shunting operation signaling control and recording, parking car operation card control and recording, outgoing shunting route contact and confirmation, outgoing shunting operation signaling control and recording, and other shunting operation control and recording.

[0072] 1. Shunting operation preparation: The relevant information of the shunting operation monitoring system based on the railway dedicated line is summarized into the integrated automation system of the marshalling yard, and displayed on the station terminal of the integrated automation system of the marshalling yard; the information summarized in this part includes: equipment status information, line status information, shunting status information and plan status information; such as Figure 3As shown, the main information content of the summary and the source of each information are listed, specifically:

[0073] (1) Figure 3 As shown, the station terminal displays in real time the position of the hand-operated turnouts in the non-centralized area, the opening and closing of the gate leaves, the opening and closing of the crossing railings, the intrusion of the operating line, and the number of stored cars on each operating line (wheel sensors are installed at the entrance and exit of the storage line. When the locomotive enters and exits the line, the wheel sensors can sense the number of wheels passing through and the direction of the wheels passing. By calculating the number of wheels entering and exiting the storage line, the number of stored cars in the storage line can be known), the number and type of stored cars, the storage time, and the anti-slip situation. If there is a shunting machine operating in the non-centralized area, the current line position of the shunting machine and the shunting hook in operation are also displayed at the same time. Specifically: wheel sensors are installed on the non-centralized running lines, storage lines, and turnouts. When the train passes the wheel sensors, the current position of the train can be sensed. The shunting operation notice marks the operating line (storage line) of each shunting hook. The shunting hook in operation can be determined by the storage line where the train is currently located.

[0074] (2) After the station terminal compiles and issues the shunting operation notification form, the system automatically pushes it to the horizontal shunting handheld console and machine controller and gives prompts. The shunting team and the driver can view and listen to the voice broadcast on the display screens of the handheld console and machine controller.

[0075] (3) All shunting signaling and voice call records during the operation are saved as different voice files according to the shunting hooks.

[0076] 2. On-line shunting route contact and confirmation: On-line shunting means that the shunting machine sends the operating vehicle to the operating track to disconnect or connect the vehicle to the operating track; in this process, the shunting team needs to enter the dedicated line section to contact the route and confirm safety. The shunting team's work includes opening the direction of the dedicated line hand switch, confirming the status of the crossing guardrail, confirming the opening status of the gate, and confirming the line limit violation. Based on the line and equipment conditions of each dedicated line, the system provides the function of route contact and safety confirmation through the combination of sensor layout and horizontal adjustment. Specifically:

[0077] (1) After the shunting machine enters the sensor deployment area of ​​the non-centralized area, the system automatically tracks the progress of the shunting operation according to the hook sequence of the shunting operation notice, and conducts safety control over the entire non-centralized shunting process. The shunting team and the driver can view the number of stored vehicles, the number and type of stored vehicles, and the anti-skid status of each operation line on the display screen of the horizontal shunting handheld console and the machine controller.

[0078] (2) After the coupler pulls the hand switch, the horizontal handheld console and the machine controller automatically announce the direction of the hand switch opening, and the station terminal synchronously updates the position of the hand switch. According to the shunting hook plan, the system automatically determines the route and switch status that the shunting locomotive needs to pass through to reach the destination track. When all the switches on the route are in place, the horizontal handheld console and the machine controller simultaneously announce that the shunting route is ready.

[0079] (3) The shunting master can check the status of the crossings, gates, switches and line intrusions on the planned routes of the two hooks at any time on the horizontal shunting handheld console. Before the shunting locomotive enters the line, the shunting master operates the "line entry check" on the horizontal shunting handheld console, and the system automatically broadcasts the crossings, gates, switches and line intrusions on the corresponding route of the current shunting hook. If the crossing guards are not lowered, the gates are not opened and locked, the switches are not in the required position and close to each other, and there are intrusions on the line, the horizontal shunting is prohibited from sending the "start" and "push" signals, and the reasons are prompted; after the system detects that the influencing reasons have been eliminated, it automatically cancels the restrictions on the "start" and "push" signals and gives a prompt; under special circumstances, the shunting master can ignore the system check by "unlocking" the horizontal shunting handheld console to lift the restrictions on the "start" and "push" signals.

[0080] 3. Signaling control and recording of on-line shunting operations.

[0081] (1) After the shunting machine enters the dedicated line enterprise, the vehicle number and sequence of the vehicle carried by the shunting machine are automatically checked (obtained through the vehicle number recognition device). If the vehicle number and sequence of the vehicle connected in the concentration area on the shunting operation notice do not match, a prompt will be given.

[0082] (2) When operating within the enterprise, after the shunting locomotive is started, it automatically tracks the position of the front end of the shunting train (determined by the first wheel passing by the wheel sensor), and automatically sends signals ("ten cars", "five cars", "three cars", "one car") to control the cars based on the automatically detected position of the parked cars (when the line is empty, it is the parking position manually set by the station terminal or the enterprise terminal). In addition, the automatically sent signals can be disabled and replaced with manual signals through the horizontal shunting handheld device in the horizontal shunting light display subsystem; at the same time, all signals are automatically recorded, and the station terminal can check the records according to the shunting hook.

[0083] (3) According to the shunting operation notice, after detecting that all vehicles involved in the current uncoupling have entered the operation line and collecting the "stop" signal, an entry record is automatically generated and prompted on the station terminal and enterprise terminal; if the current hook is a trailer, no entry record is generated. When the entry record is generated, the system checks the number of hooked vehicles on the shunting operation notice and the number of vehicles entering the line. If there is a mismatch in the number of vehicles, a prompt will be given.

[0084] 4. Card control and record of parking vehicle operation: When the parking vehicle is taken away from the non-centralized area operation track, anti-skid inspection, train test inspection, and train simple test inspection are carried out, and card control and record are carried out. Specifically:

[0085] (1) The anti-skid status can be checked and marked on the horizontal handheld console. When checking, the display shows "the parking car sequence number before coupling + car number + anti-skid method + anti-skid equipment number (only equipment with numbers)"; when marking, press "the sequence number of the distance adjustment machine + installation and withdrawal mark + anti-skid method + anti-skid equipment number". After marking, the "sequence number of the distance adjustment machine" is automatically converted into "the parking car sequence number + car number". The sequence number is marked with 2 digits. If there is only 1 digit, the tens digit is filled with 0; the installation and withdrawal mark is marked with 1 digit, including: 0-remove anti-skid, 1-install anti-skid. The anti-skid method is marked with 1 digit, including: 1-anti-skid iron shoe, 2-manual brake, 3-manual brake fastener, 4-wheel stopper, 5-anti-skid sleeper, 6-other. The anti-skid equipment number is marked with 2 digits. If there is only 1 digit, the tens digit is filled with 0. After the anti-skid mark changes, the station terminal and the enterprise terminal will display it synchronously.

[0086] (2) When a test pull is required, the horizontal adjustment handheld console can send out "request for test pull" or "test pull completed" information, which will be automatically displayed and broadcast by the horizontal adjustment machine controller and automatically recorded in the background for reference by the station terminal.

[0087] (3) When a simplified test is required, the horizontal dispatch handheld station can mark the number of vehicles for the simplified test and feedback the message "Simplified test completed". The horizontal dispatch machine controller automatically displays and broadcasts, and the background automatically records, which can be viewed by the auxiliary dispatch, cargo dispatch, and security command center monitoring terminals. The number of vehicles for the simplified test is marked with 2 digits. If there is only 1 digit, the tens digit is filled with 0.

[0088] 5. Outbound shunting route contact and confirmation: Outbound shunting means that the shunting machine leaves the non-centralized area after picking up or hooking up the car. In this process, the shunting team needs to make route contact and safety confirmation in the non-centralized area. The shunting team's work includes opening the direction of the dedicated line hand switch, confirming the status of the crossing guardrail, confirming the opening status of the gate leaf, and confirming the line intrusion. Based on the line and equipment conditions of each dedicated line, the system provides the function of route contact and safety confirmation through the combination of sensor layout and horizontal adjustment. Specifically:

[0089] (1) Before the train leaves the line, the shunter operator operates the "line check" on the horizontal shunting handheld console. In addition to automatically checking the crossings, gates, switches, and line intrusions on the current shunting hook corresponding to the approach route, the system also checks the removal of anti-slipping measures. If the anti-slipping measures of the shunting locomotive have not been removed, the horizontal shunting is prohibited from issuing the "start" and "push" signals, and the reason is prompted. The shunter operator can ignore the system check by "unlocking" the horizontal shunting handheld console to remove the restrictions on the "start" and "push" signals.

[0090] (2) If the train returns to the centralized area in the station after leaving the line, after the horizontal adjustment handheld console issues the "line leaving check" message, the station terminal and the enterprise terminal will simultaneously issue a prompt to return to the centralized area.

[0091] 6. Signaling control and recording of outgoing shunting operations.

[0092] (1) After the shunting machine is started, it automatically tracks the position of the shunting train until it completely leaves the sensor layout area (this area can be found in the previous introduction).

[0093] (2) After the shunting train is detected to have completely left the line, the number of vehicles taken out will be automatically checked, and a record of the vehicles leaving the line will be automatically generated. The number and sequence of vehicles stored on the line will be updated, and data will be updated at the station terminal and the enterprise terminal. If the number of vehicles taken out by the system is inconsistent with the number of vehicles taken out by the hook plan, a prompt will be given.

[0094] (3) If the shunting locomotive returns to the concentration area, before entering the concentration area, the vehicle number and sequence of the shunting locomotive will be automatically checked. If they do not match the last check mark (when picking up the vehicle) on the shunting operation notice, a prompt will be given.

[0095] 7. Control and record of other shunting operations. When the shunting machine performs additional operations on the shunting operation notice in the non-centralized area, the shunting operation is controlled and recorded according to the operation and confirmation of the shunting team or indoor personnel; including: control and record of operation delays and additional operations, and record of voice signaling and voice communication according to the hook plan; and provide manual modification function of equipment, track and parking car information; specifically:

[0096] (1) Operation delay.

[0097] When the shunting team is performing shunting operations, the team learns in advance that the planned completion time of this order will be later than the original plan of the shunting operation notification. The shunting master presses the button on the horizontal shunting platform to notify, the indoor section chief or assistant shunter approves and replies, and the indoor personnel record the reasons for the delay in the operation on the system for subsequent analysis.

[0098] (1) Additional homework.

[0099] When the shunting group encounters an emergency during the shunting operation and needs to perform temporary hooking or adjust the cargo position, the shunting master sends a notification to the indoor shunting section chief or assistant through the horizontal shunting platform. The indoor section chief or assistant approves the receipt and the indoor personnel make changes on the system. For example, for temporary hooking, the indoor personnel will modify the number of cars stored in the dedicated track on the system; for temporary adjustment of the cargo position, the indoor personnel will modify the number of cars stored in the cargo position on the system. When the indoor personnel complete the modification on the system, the track information of the shunting group's horizontal shunting end will be automatically updated.

[0100] (1) Record voice signaling and voice communication according to the hook plan.

[0101] When the shunting master reports the hooking plan during horizontal shunting, the system automatically records the voice signals and voice communication records before and after the hooking plan start and end reports. The system saves them according to the reports and voice content for later playback analysis. In particular, when the shunting machine is ready to enter or leave the line, the shunting master clicks the "entry check" button, and the system records the start time of this hooking; when the shunting master clicks the "exit check" button, the system records the end time of this hooking.

[0102] (4) System manual modification function.

[0103] When the on-site equipment fails and the status confirmation and track number change cannot be automatically performed, the system provides the function of manually modifying the equipment, track and parked car information. The indoor personnel can manually change the equipment, track and parked car number on the system, and the system will record it. When the indoor personnel complete the modification on the system, the system information of the shunting group horizontal shunting end is automatically updated.
