[0017] (1) The access control is closed, the switch signal lights up red, the vehicle stops at the track section in front of the switch signal, and the train waits in front of the switch signal to enter the loading and unloading operation area;

[0018] (2) The station interlocking system notifies the yard bridge safety system that a railway locomotive needs to enter the target railway loading and unloading line. The yard bridge safety system receives the information that a railway locomotive needs to enter the target railway loading and unloading line, and controls the automated yard bridge to stop the operation according to the operation progress, and locks the automated yard bridge in the loading and unloading operation area in a safe position;

[0019] (3) After the automated yard bridge is locked to a safe position, the yard bridge safety system controls the door access at the entrance of the target railway loading and unloading line to be opened. The yard bridge safety system also transmits the information of the door access being opened and the yard bridge being locked to a safe position to the station interlocking system.

After receiving the status, the yard bridge safety system locks the door access at the entrance of the target railway loading and unloading line in an open state, ensuring the safety of the door access for locomotives and vehicles entering and leaving the locomotives;

[0028] (4) The turnout signal lights up white, and the shunting locomotive enters the loading and unloading operation area. The station interlocking system detects the track section status and route unlocking information, proving that the shunting locomotive has crossed the transition section and entered the railway loading and unloading line. The turnout signal automatically turns off and lights up red, and transmits the information to the yard bridge safety system. After the yard bridge safety system receives the information that the shunting locomotive has entered the railway loading and unloading line, it controls the access control at the entrance of the target railway loading and unloading line to automatically close;

[0029] (5) The shunting locomotive continues to move forward. The station interlocking system detects that the locomotive vehicle has entered the target railway loading and unloading line. The shunting locomotive stops at the locomotive stop sign and connects the shunting locomotive with the railway container vehicle to prepare for the vehicle pickup operation. The yard bridge safety system determines that the shunting locomotive is in place based on the locomotive stop information sent by the shunting locomotive personnel and is ready to start the vehicle pickup operation;

[0030] (6) After the shunting locomotive is coupled with the railway container vehicle, it starts to move backward and prepares to exit the railway loading and unloading line. The station interlocking system detects the direction, number of axles, and track section occupancy status of the shunting locomotive, automatically determines that the shunting locomotive has started to pick up the vehicle, and notifies the yard bridge safety system that the locomotive vehicle needs to exit the target railway loading and unloading line, and requests the system to open the access control at the entrance of the target railway loading and unloading line. The yard bridge safety system receives the information and opens the access control, and transmits the information to the station interlocking system. The station interlocking system checks the transition section status, railway turnout status, and access control status, and then handles the entry and opens the access control signal to light the white light. The station interlocking system transmits the entry lock and access control signal open status to the yard bridge safety system. After receiving the status, the yard bridge safety system locks the access control in the open state to ensure the safety of the locomotive vehicle entering and exiting the access control. The shunting locomotive vehicle drives according to the access control signal display, exits the railway loading and unloading line, and crosses the access control to enter the transition section;

[0031] (7) When a shunting locomotive enters the transition section and continues to exit, the station interlocking system detects the track section clearing information and the approach unlocking information, controls the access control signal to close and lights up the red light, and transmits the shunting locomotive approach unlocking and section clearing information to the yard bridge safety system. The yard bridge safety system receives the information and controls the access control to close, and at the same time controls the yard bridge locking device to release, so that automated loading and unloading operations can be carried out in the loading and unloading operation area.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] In order to make the purpose, technical solution and advantages of the implementation of the present invention clearer, the technical solution in the embodiment of the present invention will be described in more detail below with reference to the accompanying drawings in the embodiment of the present invention.

[0042] like Figure 1 to Figure 2 As shown, this embodiment discloses a semi-automatic container railway loading and unloading line safety system, which is used for the safe operation protection of the railway loading and unloading line of the port automated container terminal. The shunting locomotive pushes the railway vehicle to the railway loading and unloading line in the port automated container terminal, and cooperates with the automated yard crane to complete the automated loading and unloading operation mode of the port railway loading and unloading line. The automated yard crane and the railway vehicle can realize safe operation. The safety system includes a yard crane safety system and a station interlocking system.

[0043] The yard crane safety system includes an access control subsystem and a yard crane operation subsystem. The access control subsystem is used to control the opening and closing of the railway access control. The yard crane operation subsystem is used to control the lifting operation of the automated yard crane in the loading and unloading operation area. The yard crane operation subsystem is also used to control the automated yard crane to stop the loading and unloading operation in the loading and unloading operation area and lock it to a safe position.

[0044] The station interlocking system is used for railway turnout control, signal opening and closing control, and also for monitoring the track section status, railway locomotive and vehicle position and running direction;

[0045] The yard crane safety system and the station interlocking system exchange information, send each other equipment working status, send each other operation requests, and lock each other. The yard crane operation track is locked during shunting operations, and the shunting operation approach and related tracks are blocked during yard crane loading and unloading operations.

[0046] Preferably, the access control subsystem includes an access control and an access control opening and closing control device. The access control is an automatic control access control, which is convenient for controlling opening and closing. By installing an automatic control access control at the railway entrance and exit of the loading and unloading operation area protection net, the automated terminal railway loading and unloading operation area and the terminal external railway operation area can be well isolated.

[0047] Preferably, the yard bridge operation subsystem includes an automated yard bridge and a yard bridge locking device. The automated yard bridge includes a yard bridge trolley, a transverse trolley and a hoist. The yard bridge operation subsystem is used for the longitudinal operation control of the yard bridge trolley, the transverse operation control of the transverse operation control and the lifting and lowering of the hoist, thereby realizing the lifting operation. The yard bridge locking device is used to lock the transverse operation control and the lifting control to a safe position. Locking the transverse operation control and the lifting control to a safe position can protect the shunting locomotive from being hit by the automated yard bridge lifting trolley and the lifting control during the process of picking up and delivering vehicles, thereby meeting the requirements for safe coordinated operation of shunting locomotives and automated yard bridges. An automated yard bridge (automated yard bridge crane, referred to as an automated yard bridge or yard bridge) is a loading and unloading machine that moves longitudinally along the track in an automated railway loading and unloading line, directly transferring container cargo between railway vehicles and horizontal transport vehicles inside the terminal. Railway locomotives push or pull vehicles in and out of the automated terminal railway loading and unloading lines, and automated yard cranes realize automated loading and unloading operations of railway containers. This can reduce port transshipment, reduce the number of handling times, reduce transshipment time, and reduce connection costs, thereby building a highly efficient integrated transportation system for rail-water transport.

[0048] Preferably, the station interlocking system includes a switch machine, a signal machine, a track circuit device, a vehicle running direction detection device and an interlocking operation control device. The signal machine includes a switch signal machine and a access control signal machine. The switch signal machine is set at the railway switch, and the access control signal machine is set at the access control machine. The switch signal machine and the access control signal machine are used to protect the safety of the railway switch, access control and loading and unloading operation areas. The track circuit device is set to facilitate the monitoring of the track section status and the position of the railway locomotive and vehicle. The vehicle running direction detection device is set to facilitate the monitoring of the vehicle running direction.

[0049] In this embodiment, the signal D1 is a turnout signal, and the signal DM1 and DM2 are access control signals. The signal D1, DM1, and DM2 are used to protect the safety of the loading and unloading operation area, access control, and 1# turnout. The signal D1, DM1, and DM2 are controlled by the station interlocking system. When the access control is closed, the red light is on to prohibit railway vehicles from passing through. When the access control is open, the white light is on to allow railway vehicles to pass. The field bridge safety system is equipped with an access control device to control the opening and closing of the access control. The access control status information is transmitted from the field bridge safety system to the station contact system. The station interlocking system obtains the access control status information and controls the opening and closing of the signal D1, DM1, and DM2 after checking the interlocking relationship. The opening and closing of the signal D1 is controlled by the station interlocking system and the access control subsystem. The opening and closing of the DM1 and DM2 signal machines are also controlled by the station interlocking system and the access control subsystem, which can effectively protect safety. Taking signal D1 as an example, the station interlocking system can control the opening of D1 signal only after the access control is opened; after D1 is opened, the access control cannot be closed; after the D1 signal is closed, the access control can be closed. In this embodiment, D1 signal is also the protection signal of 1# turnout, and DM1 and DM2 signals are also the protection signals of 1# turnout.

[0050] The shunting locomotive and vehicle completely withdraw from the loading and unloading operation area, the station interlocking system shunting approach is unlocked, and the DM1 and DM2 signals are closed. The station interlocking system transmits the approach unlocking signal closure control information to the yard bridge safety system. The yard bridge safety system notifies the access control system to close the access control, and access control 1 and access control 2 are closed. After the access control is closed, the yard bridge safety system notifies the yard bridge operation subsystem to release the locked state of the track, and the automated yard bridge performs automatic container loading and unloading operations within the automated yard protection net of the railway loading and unloading line.

[0051] Automated yard crane loading and unloading operations are given priority. The signal equipment within the control range of the station interlocking system is controlled by the station control center, which is the external interface of this system; the access control subsystem and yard crane operation subsystem are controlled by the yard crane safety system. During the automatic operation of the automated yard crane, the access control is closed, the D1, DM1, and DM2 signal machines are closed, and the lights at the signal points are prohibited.

[0052] In this embodiment, the field bridge safety system controls the horizontal and vertical lifting operations of the field bridge hoisting trolley in the loading and unloading operation area, and the longitudinal operation of the field bridge trolley along the field bridge track. The operation is stopped according to the command of the field bridge safety system. During the railway pick-up and delivery operation, the field bridge hoisting trolley is locked to a safe position where it does not come into contact with the railway vehicles on the track; and the access control system is controlled to be opened and closed. The field bridge safety system and the station interlocking system can transmit control information to each other. The interlocking system sends a request to enter the network 1G1 or 2G1 from outside the closed network and the open or closed status of the D1 signal to the field bridge safety system, and sends a request from the closed network 1G1 or 2G1 to go out of the closed network and the open and closed status of the DM1 and DM2 signals; the field bridge safety system sends the door control and door control 2 opening or closing to the interlocking system.

[0053] Preferably, the loading and unloading operation area is provided with a protective net for isolation from the outside world, a field bridge track is provided on each side of the loading and unloading operation area, the field bridge trolley straddles the two field bridge tracks, a container yard is provided on one side between the two field bridge tracks, and a railway loading and unloading line parallel to the field bridge track is provided on the other side, and a door access control and a door access control opening and closing control device are installed at the entrance protective net of the railway loading and unloading line, a railway turnout is provided outside the protective net, and a transition section is provided between the railway turnout and the railway loading and unloading line. In this embodiment, the automated container railway loading and unloading line is fully enclosed and isolated from the outside world. When the automated loading and unloading equipment is in operation, personnel and railway locomotives are prohibited from staying and moving in the operation area. The railway vehicles use container flat cars or open cars, and automated rail-type container gantry cranes are provided for loading and unloading operations. When the automated rail-type field bridge in the railway loading and unloading area loads and unloads containers, it operates in an automated manner, and the field bridge trolley can move longitudinally on the two field bridge tracks, which can facilitate loading and unloading operations.

[0054] The following is a further explanation of the example of setting a railway turnout outside the protective net and setting two railway loading and unloading lines inside the protective net. The overall layout of the system during specific implementation can be adjusted with reference to this embodiment. In this embodiment, the railway turnout is 1# turnout, and a D1 signal is set in front of the turnout. The transition section between the first railway loading and unloading line and the railway turnout is the 1DG section, and the transition section between the second railway loading and unloading line and the railway turnout is the 1DG1 section. Furthermore, in this embodiment, access control 1 and DM1 signal are set at the entrance of the first railway loading and unloading line, access control 2 and DM2 signal are set at the entrance of the second railway loading and unloading line, and axle counting equipment JZ11 is set at the boundary between the 1G1 section and the 1G section, and axle counting equipment JZ21 is set at the boundary between the 2G1 section and the 2G section.

[0055] Preferably, locomotive stop signs are set on one side of the two railway loading and unloading lines. The locomotive stop signs are used to indicate the parking position of the shunting locomotive during vehicle picking and delivering operations, to avoid collision safety accidents caused by the shunting locomotive invading the operating area of ​​the automated yard bridge, and to coordinate the interactive operations of the shunting locomotive and the automated yard bridge within the railway loading and unloading line. The locomotive stop sign is set at the boundary of the operating area of ​​the automated yard bridge near the access control, that is, the railway loading and unloading line is provided with a locomotive stop sign at the boundary of the automated yard bridge operating area (the boundary where the yard crane can carry out railway vehicle loading and unloading operations and will not collide with the shunting locomotive). For the safety of the locomotive, the shunting locomotive enters the boundary stop sign position of the loading and unloading line and stops, and shall not cross it. However, all railway container vehicles are required to cross the locomotive stop sign position to enter the yard bridge loading and unloading operation area.

[0056] Preferably, the railway loading and unloading line includes a first section and a second section. In this embodiment, the first railway loading and unloading line includes 1G1, 1G track sections arranged on the inner side of access control 1, and 1DG section is arranged on the outer side of access control 1. The second railway loading and unloading line includes 2G1, 2G track sections arranged on the inner side of access control 2, and 1DG1 section is arranged on the outer side of access control 2. The boundary between the first section and the second section is located at the position of the shunting locomotive parking area added outside the operating boundary of the automated yard crane hoist (the shunting locomotive parking area is about 30m, the length of a locomotive), that is, the shunting locomotive parking area is between the boundary between the first section and the second section and the locomotive parking sign, which is convenient for parking shunting locomotives.

[0057] Preferably, each track section, such as the transition section, the first section and the second section, is provided with a track circuit device, which is used to monitor the track section status and the position of the railway locomotive and vehicle. The 1DG, 1G1 and 1G track sections are all controlled by the station interlocking system, and the 1DG1, 2G1 and 2G track sections are also controlled by the station interlocking system. A vehicle running direction detection device is provided at the boundary between the first section and the second section. In this embodiment, the vehicle running direction detection device adopts an axle counting device. The track section can be used to detect the position and timing of trains, shunting locomotives and trains entering and exiting the loading and unloading line station, and to judge the vehicle running direction, etc., and to judge the position and progress of railway operations. During specific implementation, the railway vehicle position monitoring device of the track section may be a track circuit device, an axle counting device, a vehicle number recognition device, a radar device, a video image recognition device, etc. In this embodiment, the railway vehicle position monitoring device is preferably a track circuit device. A track circuit device is set in each track section, and an axle counting device (i.e., an axle counting device) is set at the boundary between the first section and the second section, thereby being able to well detect the position, number and running direction of railway vehicles in a section.

[0058] The D1, DM1, DM2 signal machines, 1# turnout, 1DG, 1DG1, 1G1, 2G1, 1G, 2G track circuit devices and other equipment are all controlled by the station interlocking system. In normal conditions, the D1, DM1, DM2 signal machines light up red lights, prohibiting railway vehicles from crossing. The station interlocking system and the yard bridge safety system are adjacent control systems, with control information being transmitted and interlocked.

[0059] by Figure 2 Take the axle counting device JZ11 in the railway loading and unloading line as an example. When a railway locomotive passes through the axle counting device JZ11 from the 1G1 section and enters the 1G section, the two magnetic head sensors of the axle counting device from left to right can record the running direction of the following train from left to right and the number of vehicle wheels passing through the device from 1G1 to the adjacent section 1G. Conversely, when a railway locomotive passes through the axle counting device JZ11 from the 1G section and enters the 1G1 section, the two magnetic head sensors of the axle counting device from right to left can record the running direction of the following train from right to left and the number of vehicle wheels passing through the device from 1G to the adjacent section 1G1. The axle counting device JZ11 can detect the arrival of vehicles, calculate the number of vehicle axles, determine the vehicle running direction information, and detect the occupied or idle status of the track section 1G.

[0060] This embodiment also discloses a semi-automatic container railway loading and unloading line vehicle delivery operation method, according to the vehicle delivery operation plan (taking 1G vehicle delivery as an example), the shunting locomotive pushes the railway container vehicle through the 1# turnout to the 1G loading and unloading area, that is, the shunting locomotive pushes the railway container vehicle through the railway turnout to the target railway loading and unloading line in the loading and unloading operation area, including the following steps:

[0061] (1) Gate 1 is closed, the D1 signal turns red, the vehicle stops in the track section before the D1 signal, and the train waits in front of the D1 signal to enter the loading and unloading area;

[0062] (2) The station interlocking system notifies the yard crane safety system that a railway rolling stock needs to enter the 1G section. The yard crane safety system receives the information that a railway rolling stock needs to enter the 1G section, and according to the operation progress, controls the yard crane to stop the operation, and locks the automated yard crane in the loading and unloading operation area in a safe position (the transverse trolley and hoist leave the 1G railway system operation range and are locked).
