The signal transmission process is made of a radio signal transmission according to the operation of the train driver and the radio control signal transmitted from the train side to the screen door side is characterized in that the RF signal and the infrared signal is transmitted at the same time.
상기 과정에서 열차측으로부터 송출된 무선 제어신호는 스크린도어측의 신호수신부(200)를 통해 수신되며, 수신된 스크린도어의 무선 제어신호는 중앙제어부(300)로 전달된다(S12).In the process, the radio control signal transmitted from the train side is received through the signal receiver 200 on the screen door side, and the radio control signal of the received screen door is transmitted to the central controller 300 (S12).
중앙제어부(300)는 상기에서 수신된 무선 제어신호가 스크린도어의 열림 또는 닫힘 동작중 어떤 행위를 제어하고자 하는지 판단하는 과정이 뒤따르며(S13), 상기의 무선 제어신호가 스크린도어의 열림동작을 제어하는 신호로 판단되면 각각의 개별제어부(400)를 통해 스크린도어부(500)의 도어구동모터(510)를 도어 열림방향으로 구동한다(S14). 상기에서 도어구동모터(510)의 구동은 스크린도어부(500)의 열림동작시 리미트스위치로 이루어진 도어열림감지부(521)의 동작 감지 시점까지 진행되며(S15), 상기의 도어열림감지부(521)의 동작감지로 스크린도어부(500)가 모두 오픈되었다고 판단되면 도어구동모터(510)를 정지한다(S16).The central control unit 300 is followed by a process of determining which action the wireless control signal received above is to control during the opening or closing operation of the screen door (S13), wherein the wireless control signal performs the opening operation of the screen door. If it is determined that the control signal is driven through the respective control unit 400, the door driving motor 510 of the screen door unit 500 is driven in the door opening direction (S14). The driving of the door driving motor 510 proceeds to the operation detection time of the door opening detecting unit 521 consisting of a limit switch during the opening operation of the screen door unit 500 (S15), and the door opening detecting unit (S15). When it is determined that the screen door part 500 is all open by the operation detection of 521, the door driving motor 510 is stopped (S16).
상기에서 스크린도어부(500)의 열림 동작시 열차와 스크린도어부(500) 사이에 형성된 간격을 차단하고자 게이트도어부(600)의 작동이 이루어지며 이는 게이트구동모터(610)를 게이트 닫힘 방향으로 구동하여 열차와 스크린도어부(500) 사이의 간격을 차단한다(S17). 상기에서 게이트구동모터(610)의 구동은 게이트 닫힘동작에 따라 리미트스위치로 이루어진 게이트닫힘감지부(622)의 동작 감지 시점까지 진행되며(S18), 상기의 게이트닫힘감지부(622)의 동작감지로 게이트도어부(600)가 열차와 스크린도어부(500) 사이의 간격을 모두 차단하였다고 판단되면 게이트구동모터 (610)를 정지한다(S19).The gate door 600 is operated to block the gap formed between the train and the screen door 500 during the opening operation of the screen door 500, which moves the gate driving motor 610 in the gate closing direction. Drive to block the gap between the train and the screen door 500 (S17). The driving of the gate driving motor 610 proceeds to the operation detection time of the gate closing detection unit 622 consisting of a limit switch according to the gate closing operation (S18), and the operation detection of the gate closing detection unit 622. When it is determined that the low gate door part 600 blocks all the gaps between the train and the screen door part 500, the gate driving motor 610 is stopped (S19).
또한, 상기의 스크린도어부(500)의 열림 동작시 승강장과 열차사이에 형성된 틈새를 차단하기 위하여 안전발판(700)의 작동이 이루어지며 이는 발판구동모터(710)를 안전발판(700) 닫힘 방향으로 구동하여 승강장과 열차 사이에 형성된 간격을 차단한다(S20). 상기에서 발판구동모터(710)의 구동은 안전발판(700)이 틈새를 차단하고자 안전발판의 닫힘 동작시 리미트스위치로 이루어진 발판닫힘감지부(722)의 동작 감지 시점까지 진행되며(S21), 상기의 발판닫힘감지부(722)의 동작감지로 안전발판(700)이 승강장과 열차사이에 형성된 발밑 틈새를 모두 차단하였다고 판단되면 발판구동모터(710)를 정지한다(S22).In addition, the operation of the safety footrest 700 is made in order to block the gap formed between the platform and the train during the opening operation of the screen door part 500, which is the footrest driving motor 710 to the safety footrest 700 closing direction Drives to block the gap formed between the platform and the train (S20). In the above, the driving of the scaffold driving motor 710 proceeds until the operation detection time of the foot closing detection unit 722 consisting of a limit switch during the closing operation of the safety footrest to block the gap (S21). When it is determined that the safety footrest 700 blocks all of the gaps formed between the platform and the train by the motion detection of the footrest closing unit 722, the foothold driving motor 710 is stopped (S22).
상기에서의 스크린도어부(500)와, 게이트도어부(600)와, 안전발판(700)의 동작 완료여부는 각각 도어열림감지부(521)와, 게이트닫힘감지부(622)와, 발판닫힘감지부(722)의 동작 감지여부에 따라 알 수 있으며, 상기에서 스크린도어부(500)와, 게이트도어부(600)와, 안전발판(700)의 동작이 모두 완료되었다고 판단되면 스크린도어의 열림 동작 과정을 종료하고, 만일 상기에서 스크린도어부(500)와, 게이트도어부(600)와, 안전발판(700)의 동작이 모두 완료되지 않았다고 판단되면 완료 시점까지 해당 구동모터의 작동은 계속된다.The operation of the screen door part 500, the gate door part 600, and the safety footrest 700 in the above is completed by the door open detecting part 521, the gate closing detecting part 622, and the foot closing, respectively.

상기의 무선 제어신호가 스크린도어의 닫힘 동작을 제어하는 신호로 판단되면 각각의 개별제어부(400)를 통해 스크린도어부(500)의 도어구동모터(510)를 스크린도어 닫힘 방향으로 구동한다(S31). 이때, 도어구동모터(510)가 고속으로 회전토록 전류치를 인가함으로써 스크린도어가 빠르게 닫히도록 한다.When the wireless control signal is determined to be a signal for controlling the closing operation of the screen door, the door driving motor 510 of the screen door unit 500 is driven through the respective control unit 400 in the screen door closing direction (S31). ). At this time, the door driving motor 510 to close the screen door quickly by applying a current value to rotate at high speed.
상기에서 도어구동모터(510)의 고속 회전은 스크린도어의 닫힘 동작을 빠르게 제어하나 도어의 닫힘 동작이 절반정도 이루어지면 나머지 절반의 닫힘동작은 안전상 천천히 동작토록 한다. 이러한 동작시점을 제공하는 것은 리미트스위치로 형성된 도어중간감지부(523)의 동작 감지로 이루어진다. 도어구동모터(510)의 고속 회전으로 스크린도어의 닫힘동작이 빠르게 진행되던 중 도어중간감지부(523)의 동작이 감지되면(S32), 도어구동모터(510)로 인가되는 전류치를 조절 함으로써 도어구동모터(510)를 저속 회전토록 한다(S33).The high speed rotation of the door driving motor 510 controls the closing operation of the screen door quickly, but when the closing operation of the door is made about half, the closing operation of the other half is allowed to operate slowly for safety. Providing such an operation point is made by detecting the operation of the door middle detection unit 523 formed by the limit switch. When the operation of the door middle detection unit 523 is detected while the screen door closing operation is rapidly progressed by the high speed rotation of the door driving motor 510 (S32), the door is controlled by adjusting the current value applied to the door driving motor 510. The driving motor 510 is rotated at low speed (S33).
스크린도어가 모두 닫혔는지 여부는 리미트스위치로 형성된 도어닫힘감지부(522)의 동작 감지로 판단하며, 도어닫힘감지부(522)의 동작이 감지되면(S34), 도어구동모터(510)의 구동을 정지한다(S35).Whether all the screen doors are closed is determined by the operation detection of the door closing detection unit 522 formed by the limit switch, and when the operation of the door closing detection unit 522 is detected (S34), the driving of the door driving motor 510 is performed. Stop (S35).
상기에서 스크린도어부(500)의 닫힘 동작시 열차와 스크린도어부(500) 사이를 차단하고 있던 게이트도어부(600)가 열리며 다시 원위치로 복귀하는 동작이 이루어지고, 이는 게이트구동모터(610)가 게이트도어부(600)의 열림 방향으로 구동하 며 이루어진다(S36). 상기에서 게이트구동모터(610)의 구동은 리미트스위치로 이루어진 게이트열림감지부(621)의 동작 감지 시점까지 진행되며(S37), 상기의 게이트열림감지부(621)의 동작감지로 게이트도어부(600)가 원위치로 복귀되었다고 판단되면 게이트구동모터(610)를 정지한다(S38).When the screen door 500 is closed, the gate door 600 that is blocking the train and the screen door 500 is opened and returns to its original position, which is a gate driving motor 610. ) Is made while driving in the opening direction of the gate door 600 (S36). The driving of the gate driving motor 610 proceeds until the operation detection time of the gate opening detection unit 621 formed of the limit switch (S37), and the gate door unit (S) as the operation detection of the gate opening detection unit 621. If it is determined that 600 is returned to the original position, the gate driving motor 610 is stopped (S38).
