Description

철도차량의 주차제동 제어시스템{Parking brake control system of train}Parking brake control system of train

본 발명은 철도차량의 주차제동 제어시스템으로서, 특히 철도차량이 주차제동 체결 상태에서 무인운전에서 유인운전으로 절환시 의도치 않게 주체제동이 완해되는 것을 방지하는 것에 관한 것이다.The present invention relates to a parking brake control system for a railway vehicle, and in particular, to prevent unintentional completion of subject braking when a railway vehicle is switched from unmanned operation to manned operation in the state of parking braking.

무인운전 철도차량에서 주차제동의 체결 또는 완해 제어는 TCMS(Train Control and Monitoring System)의 출력에 의해서 자동으로 체결 또는 완해 제어가 가능하다. 하지만 유인운전으로 모드를 절환하는 경우 TCMS 출력이 소프트웨어적으로 차단되고 더이상 활성화되지 않게 되므로 운전대에 위치하는 별도의 주차제동 체결/완해 버튼을 통해 유인운전으로 절환된 철도차량의 주차제동 체결 또는 완해 제어가 된다.Parking or braking control of unmanned driving railway vehicles can be automatically locked or controlled by the output of the TCMS (Train Control and Monitoring System). However, when the mode is switched by manned driving, the TCMS output is blocked by software and no longer activated, so the parking brake of the railroad car switched by manned operation is controlled through the separate parking brake sign/release button located on the steering wheel. Becomes

그러나, 무인운전 철도차량이 주차제동을 체결한 상태에서 유인운전으로 운전모드를 절환하는 경우, 유인운전 시 사용하는 운전대에 있는 주차제동 체결/완해 버튼이 완해 상태로 되어 있으면 운전모드 절환과 동시에 의도치 않게 주차제동이 완해되는 경우가 발생하는 문제가 있었다.However, when switching the driving mode by manned driving while the unmanned railroad vehicle is in parking braking, if the parking braking fastening/releasing button on the steering wheel used for manned driving is in the relaxed state, it is intended to change the driving mode at the same time. There was a problem in that parking braking was loosened unexpectedly.

이하, 본 발명의 바람직한 실시 예를 첨부한 도면에 의거하여 상세하게 설명하면 다음과 같다. Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 종래의 철도차량의 주차제동 제어시스템을 개략적으로 도시한 도면이다.1 is a view schematically showing a parking brake control system of a conventional railway vehicle.

도 2는 본 발명의 일 실시 예인 철도차량의 주차제동 제어시스템을 개략적으로 도시한 도면이다.2 is a view schematically showing a parking braking control system for a railway vehicle, which is an embodiment of the present invention.

도 2를 참조하면, 본 발명에 따른 철도차량의 주차제동 제어시스템은, 체결/완해 버튼(100), TCMS(200), 주차제동 계전기(300) 및 보조계전기(400)를 포함하여 구성된다.Referring to Figure 2, the parking brake control system of a railway vehicle according to the present invention, is configured to include a fastening / release button 100, TCMS 200, parking brake relay 300 and auxiliary relay 400.

상기 체결/완해 버튼(100)은 철도차량의 유인운전 모드에서 주차제동을 제어한다. The fastening/releasing button 100 controls parking braking in the manned driving mode of the railway vehicle.

상기 체결/완해 버튼(100)을 체결 또는 완해 상태로 함으로써 철도차량의 주차제동을 체결 또는 완해할 수 있다. 일반적으로 도 1과 같은 경우, 상기 체결/완해 버튼(100)을 체결 상태로 하면 주차제동 계전기(300)가 소자 상태가 되어 상기 철도차량의 주차제동이 체결된다. 또한 상기 체결/완해 버튼(100)을 완해 상태로 하면 상기 주차제동 계전기(300)가 여자 상태가 되어 상기 철도차량의 주차자동이 완해 된다.The parking/braking of the railway vehicle can be concluded or completed by setting the fastening/releasing button 100 to a fastening or releasing state. In general, in the case of FIG. 1, when the fastening/releasing button 100 is in a fastened state, the parking brake relay 300 is in an elemental state, and the parking brake of the railway vehicle is fastened. In addition, when the fastening/releasing button 100 is in a relaxed state, the parking brake relay 300 is in an excited state, and parking automatic of the railway vehicle is completed.

상기 TCMS(200)는 철도차량의 무인운전 모드에서 주차제동을 제어한다. The TCMS 200 controls parking braking in an unmanned driving mode of a railway vehicle.

상기 TCMS(200)는 주차제동 체결 또는 완해 신호를 출력하여 상기 철도차량의 주차제동을 제어한다. 일반적으로 도 1과 같은 경우, 상기 TCMS(200)에서 주차제동 체결 신호를 출력하면 상기 주차제동 계전기(300)가 소자 상태가 되어 상기 철도차량의 주차제동을 체결할 수 있다. 또한, 상기 TCMS(200)에서 주차제동 완해 신호를 출력하면 상기 주차제동 계전기(300)가 여자 상태가 되어 상기 철도차량의 주차제동을 완해할 수 있다.The TCMS 200 controls the parking braking of the railway vehicle by outputting a parking brake sign or a completion signal. In general, in the case of FIG. 1, when the parking brake signal is output from the TCMS 200, the parking brake relay 300 is in a device state, so that the parking brake of the railway vehicle can be fastened. In addition, when the parking brake completion signal is output from the TCMS 200, the parking brake relay 300 may be in an excited state to complete parking braking of the railway vehicle.

상기 보조계전기(400)는 상기 체결/완해 버튼(100), TCMS(200) 및 주차제동 계전기(300)와 연결되어 철도차량의 주차제동 체결 상태를 보조한다. 상기 보조계전기(400)는 무인운전 모드의 철도차량이 주차제동 체결 상태에 있는 경우 소자 상태가 되고, 무인운전 모드의 철도차량이 주차제동 완해 상태에 있는 경우에도 소자 상태가 된다.The auxiliary relay 400 is connected to the fastening/releasing button 100, the TCMS 200, and the parking brake relay 300 to assist the parking brake fastening state of the railway vehicle. The auxiliary relay 400 is in a device state when the railway vehicle in the unmanned driving mode is in the parking braking engagement state, and also in the device state even when the railway vehicle in the unmanned driving mode is in the parking braking completion state.

즉, 상기 보조계전기(400)는 상기 철도차량이 무인운전 모드에서 주차제동 체결 상태인 경우 유인운전 모드로 절환시 일단 소자 상태를 유지한다.That is, the auxiliary relay 400 maintains the element state once when the railway vehicle is switched to the manned driving mode when the parking brake is in the unmanned driving mode.

따라서, 상기 보조계전기(400)는 무인운전 모드의 철도차량이 주차제동 체결 상태에서 유인운전 모드로 절환 시 소자 상태를 유지하고 상기 철도차량의 주차제동 체결 상태를 유지할 수 있다.Accordingly, the auxiliary relay 400 may maintain the device state when the railway vehicle in the unmanned driving mode is switched from the parking braking fastening state to the manned driving mode and maintain the parking braking fastening state of the railway vehicle.

보다 구체적으로, 상기 무인운전 모드의 철도차량이 주차제동 체결 상태에서 유인운전 모드로 절환될 때, 상기 체결/완해 버튼(100)이 완해 상태에 있는 경우라도 상기 보조계전기(400)가 소자 상태에 있기 때문에 상기 철도차량은 주차제동 체결 상태를 유지한다. 이 상태에서, 상기 체결/완해 버튼(100)을 체결 상태로 선택해야 상기 보조계전기(400)는 여자되고 상기 보조계전기(400)가 여자 상태가 된 후 상기 체결/완해 버튼(100)을 완해 상태로 선택하여 상기 철도차량의 주차제동을 완해할 수 있다.More specifically, when the railway vehicle in the unmanned driving mode is switched from the parking braking fastening state to the manned driving mode, the auxiliary relay 400 remains in the device state even when the fastening/releasing button 100 is in the relaxed state. Because of this, the railroad vehicle maintains the parking brake. In this state, when the fastening/release button 100 is selected as the fastening state, the auxiliary relay 400 is excited, and after the auxiliary relay 400 is excited, the fastening/release button 100 is completed. You can choose to complete the parking brake of the railway vehicle.

즉, 상기 철도차량이 무인운전에서 유인운전 모드로 절환될 때 주차제동이 이미 체결되어 있는 상태라면 먼저 상기 체결/완해 버튼(100)을 눌러 체결 위치로 선택하여 아직 여자되지 않은 상기 보조계전기(400)를 먼저 여자시켜주는 단계를 거쳐야만 주차제동을 완해할 수 있다.That is, if the parking brake is already engaged when the railway vehicle is switched from unmanned operation to manned operation mode, first press the fastening/releasing button 100 to select the fastening position, and the auxiliary relay 400 that has not yet been excited ), you must go through the steps to excite the woman before you can complete the parking brake.

상기 보조계전기(400)가 철도차량의 주차제동 시스템에 포함됨으로써, 상기 무인운전 모드의 철도차량이 주차제동 체결 상태에서 유인운전 모드로 절환 될 때, 유인운전 모드에서 주차제동을 제어하는 체결/완해 버튼(100)이 완해 상태에 있더라도 상기 보조계전기(400)가 소자 상태를 유지함으로써 상기 철도차량의 주차제동이 체결 상태를 유지하여 발생할 수 있는 안전사고에 대비할 수 있다.When the auxiliary relay 400 is included in the parking braking system of the railway vehicle, when the railway vehicle in the unmanned driving mode is switched from the parking braking state to the manned driving mode, the fastening/release to control the parking brake in the manned driving mode Even when the button 100 is in the relaxed state, the auxiliary relay 400 maintains the element state, so that the parking brake of the railway vehicle can be maintained in a locked state to prepare for a safety accident that may occur.

본 발명의 권리범위는 상술한 실시 예에 한정되는 것이 아니라 첨부된 특허청구범위 내에서 다양한 형태의 실시 예로 구현될 수 있다. 특허청구범위에서 청구하는 본 발명의 요지를 벗어남이 없이 당해 발명이 속하는 기술분야에서 통상의 지식을 가진자라면 누구든지 변형 가능한 다양한 범위까지 본 발명의 청구범위 기재의 범위 내에 있는 것으로 본다. The scope of the present invention is not limited to the above-described embodiments, but may be implemented as various types of embodiments within the scope of the appended claims. Any person skilled in the art to which the present invention pertains without departing from the gist of the present invention as claimed in the claims is deemed to be within the scope of the claims of the present invention to a wide range that can be modified.
