Description

Technical Field

[0001] The present invention relates to the technical field of rail vehicle control, and particularly to a full-automatic coupler coupling monitoring system, a decoupling control system and method. Background Art

[0002] The statements in this part only provide background technical information related to the present invention and do not necessarily constitute prior art.

[0003] The couplers on rail vehicles are divided into two parts: mechanical couplers and electrical couplers. The mechanical couplers are used to achieve the physical connection between two trains, and the electrical couplers are used to achieve the electrical connection between two trains. The processes of coupler coupling and decoupling are related to vehicle safety. There may also be risks such as loose coupling and accidental uncoupling after the coupler is coupled. Therefore, monitoring whether the coupler coupling state is normal is a very important link.

[0004] For the traditional mechanical coupler coupling state confirmation, it is checked manually whether the scale lines on the indicator above the coupler coincide, which has problems such as low efficiency and inability to monitor the coupler coupling state in real time on the vehicle. Moreover, the traditional decoupling control does not fully consider the prerequisite conditions for decoupling operations, such as the coupler being in the coupled state and the vehicle being at zero speed, which may pose a risk of vehicle decoupling caused by misoperation and affect vehicle safety. Summary of the Invention

[0005] To solve the above problems, the present invention proposes a full-automatic coupler coupling monitoring system, a decoupling control system and method. The full-automatic mechanical coupler coupling monitoring is realized by using two limit switches, the monitoring of the electrical coupler coupling state is realized by the feedback of the electrical connector, and the automatic decoupling of the coupler can be realized by pressing the decoupling button.

[0006] According to the first aspect of the embodiments of the present invention, a full-automatic coupler coupling monitoring system is provided, including: a mechanical coupler coupling monitoring system; the mechanical coupler coupling monitoring system includes: a first limit switch arranged on the main shaft of the mechanical coupler of the rail vehicle and a second limit switch arranged on the coupling rod; the normally open contacts of the first limit switch and the second limit switch are connected in series to form a series branch, and the vehicle TCMS system is connected to the series branch; a mechanical coupler coupling relay is connected to the series branch.

[0007] As a further solution, when the vehicle is in a state of waiting for coupling, the normally open contacts of the first limit switch and the second limit switch are disconnected, the series branch is not conducting; the coupling feedback signal is at a low level, the coupler coupling relay KAMHC loses power, and a signal is fed back to the TCMS.

[0008] As a further solution, after the vehicle coupling is completed, the normally open contacts of the first limit switch and the second limit switch are closed, the series branch is turned on, the coupling feedback signal is at a high level, the coupler coupling relay KAMHC is energized, and the signal is fed back to the TCMS.

[0011] After the mechanical coupler is coupled, the coupling of the electric coupler is automatically triggered, and the pushing cylinder pushes the first moving contact and the second moving contact forward so that the first moving contact contacts the second static contact and the second moving contact contacts the first static contact to realize the electrical coupling of the first vehicle and the second vehicle; at the same time, the electrical coupling signal is fed back to the TCMS.

[0012] As a further solution, after the TCMS receives the signal of mechanical coupling or electrical coupling, it displays the current coupling state and lights up the corresponding indicator light.

[0014] When the vehicle is at zero speed and the mechanical coupler is in the coupled state, the normally open contacts of the zero-speed relay and the mechanical coupler coupling relay are closed; if the decoupling button is pressed, the decoupling solenoid valve is energized and actuated, the electric coupler disengages and retracts, and the pneumatic decoupling cylinder makes the mechanical coupler coupling assembly complete decoupling.

[0015] According to the third aspect of the embodiments of the present invention, a full-automatic coupler coupling monitoring method is provided, including:

[0016] When the normally open contacts of the first limit switch arranged on the main shaft of the mechanical coupler of the rail vehicle and the second limit switch arranged on the coupling rod are both closed, the mechanical coupler coupling relay is energized and the signal is fed back to the TCMS;

[0017] Otherwise, the mechanical coupler coupling relay is not energized and the signal is fed back to the TCMS.

[0018] As a further solution, it further includes: after the mechanical coupler is coupled, the coupling of the electrical coupler is automatically triggered, and the pushing cylinder pushes the first moving contact and the second moving contact forward, so that the first moving contact contacts the second stationary contact, and the second moving contact contacts the first stationary contact, realizing the electrical coupling of the first vehicle and the second vehicle; at the same time, the electrical coupling signal is fed back to the TCMS.

[0032] In the case of no conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other.

[0033] Embodiment 1

[0034] In one or more embodiments, a full-automatic coupler connection monitoring system is disclosed, including: a mechanical coupler connection monitoring system; combined Figure 1 and Figure 2 , the mechanical coupler connection monitoring system includes: a first limit switch provided on the main shaft of the mechanical coupler of the rail vehicle and a second limit switch provided on the coupling rod. Normally open contacts are provided in both the first limit switch and the second limit switch. After the normally open contacts of the two are connected in series, one end is connected to the DC110V+ power supply, and the other end is divided into two paths. One path is connected to the TCMS, and the other path is connected to the DC110V- power supply through the mechanical coupler connection relay coil KAMHC to form a series branch, realizing the linkage monitoring of the positions of the main shaft and the coupling rod, and grounding through the coupler junction box.

[0035] When the vehicle is in the state of waiting for connection, the first limit switch S1 and the second limit switch S2 are disconnected, and their normally open contacts are all disconnected, and the series branch is not conducting; at this time, the mechanical coupler connection feedback signal is at a low level, the mechanical coupler connection relay coil KAMHC loses power, and the TCMS monitors that the vehicle is in the state of waiting for connection.

[0036] After the head car's mechanical coupler is successfully coupled, both the first limit switch S1 and the second limit switch S2 are closed, and their normally open contacts are also closed, making the series branch conductive. At this time, the mechanical coupler coupling feedback signal is at a high level, the mechanical coupler coupling relay coil KAMHC is energized, and TCMS monitors that the mechanical coupler coupling feedback signal is valid. It shows on the TCMS display screen that the current vehicle is in the coupled state, and at the same time, it drives the coupler coupling indicator light to turn on.

[0037] Furthermore, the full-automatic coupler coupling monitoring system further includes: an electrical coupler coupling monitoring system; combined with Figure 3 , the electrical coupler coupling monitoring system includes: the first static contacts B1, B2 and the first moving contacts A1, A2 arranged on the first vehicle, the second static contacts B1, B2 and the second moving contacts A1, A2 arranged on the second vehicle; and a push cylinder for pushing the moving contacts. When the mechanical coupler coupling is completed, the coupling of the electrical coupler is automatically triggered. The push cylinder pushes the first moving contact and the second moving contact forward so that the first moving contact contacts the second static contact and the second moving contact contacts the first static contact, realizing the electrical coupling between the first vehicle and the second vehicle. The vehicle's DC110V power supply feeds back a signal to TCMS through the electrical connector. When TCMS of the vehicle collects a high level, it obtains the electrical coupler coupling signal, and the TCMS display screen shows that the current electrical coupler coupling is completed.

[0038] As a further solution, based on the above full-automatic coupler coupling monitoring system, this embodiment also discloses a full-automatic coupler uncoupling control system, combined with Figure 4 , including: the normally open contacts of the zero-speed relay KAZV, the uncoupling button SBEHC, the normally open contacts of the mechanical coupler coupling relay KAMHC, and the uncoupling solenoid valve P02 connected in series in sequence;

[0039] When the vehicle is at zero speed and the mechanical coupler is in the coupled state, the normally open contacts of the zero-speed relay and the normally open contacts of the mechanical coupler coupling relay are closed. If the uncoupling button is pressed, the uncoupling solenoid valve is energized and operates, the electrical coupler disengages and retracts, and the pneumatic uncoupling cylinder causes the mechanical coupler assembly to complete uncoupling. Specifically, after operating the uncoupling button, the uncoupling solenoid valve is energized and operates, filling the uncoupling pipeline with air. The compressed air passes from the vehicle body through the uncoupling pipeline to the pneumatic uncoupling cylinder, and the pneumatic uncoupling cylinder operates to make the mechanical coupler fall off.

[0040] In this embodiment, the full-automatic mechanical coupler coupling feedback uses two limit switches to realize the position linkage between the main shaft and the coupling rod. By connecting the limit switch contacts in series, TCMS monitors the entire mechanical coupling state and drives the coupler coupling relay for uncoupling control. The electrical coupler feeds back a signal to the TCMS system for monitoring after being coupled through the electrical connector. When the vehicle needs to be uncoupled, when the coupler is coupled and the vehicle is at zero speed, the full-automatic coupler is automatically uncoupled by pressing the uncoupling button in the driver's cab.

[0041] Embodiment 2

[0042] In one or more embodiments, a full-automatic coupler coupling monitoring method is disclosed, including:

[0043] When the normally open contacts of the first limit switch S1 arranged on the main shaft of the mechanical coupler of the rail vehicle and the second limit switch S2 arranged on the coupling rod are both closed, the mechanical coupler coupling relay is energized and feeds back a signal to the TCMS; the mechanical coupler can be coupled only when the two limit switches are closed simultaneously, otherwise, the mechanical coupler coupling relay is not energized and feeds back a signal to the TCMS.

[0044] Furthermore, the full-automatic coupler coupling monitoring method of this embodiment further includes: after the mechanical coupler coupling is completed, the coupling of the electrical coupler is automatically triggered, and the pushing cylinder pushes the first moving contact and the second moving contact forward so that the first moving contact contacts the second static contact and the second moving contact contacts the first static contact, realizing the electrical coupling of the first vehicle and the second vehicle; at the same time, the electrical coupling signal is fed back to the TCMS.

[0045] Based on the full-automatic coupler uncoupling control system in Embodiment 1 and the above full-automatic coupler coupling monitoring method, this embodiment also discloses a full-automatic coupler uncoupling control method, specifically including: when the vehicle is at zero speed and the mechanical coupler is in the coupled state at the same time, the normally open contact of the zero-speed relay KAZV is closed, the uncoupling button is pressed, and the normally open contact of the mechanical coupler coupling relay KAMHC is closed. At this time, the uncoupling solenoid valve is energized and actuated, the electrical coupler disengages and retracts, and the pneumatic uncoupling cylinder causes the mechanical coupler coupling assembly to complete uncoupling.

[0048] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the above embodiments, those of ordinary skill in the art should understand that: the specific implementation manners of the present invention can still be modified or equivalently replaced, and any modification or equivalent replacement without departing from the spirit and scope of the present invention shall be covered by the protection scope of the claims of the present invention.
