Description
본 발명은 버스 도어의 안전 개폐방법에 관한 것으로, 보다 상세하게는 도어의 열림 상태를 제어하는 포토센서의 제어로직을 이용한 버스 도어의 안전 개폐방법에 관한 것이다.The present invention relates to a safe opening and closing method of the bus door, and more particularly to a safe opening and closing method of the bus door using the control logic of the photosensor for controlling the open state of the door.
일반적으로 버스와 같은 도어 개폐형태에는 슬라이딩 개폐형과 접이(Folding)식 개폐형 등이 있는데, 이러한 형태들의 도어에는 승객의 승하차시에 도어가 열려 있는 동안에 차량이 출발하지 못하도록 안전장치가 마련되어있다.In general, door opening and closing forms such as buses include sliding opening and closing and folding opening and closing types, and these types of doors are provided with a safety device to prevent the vehicle from starting while the door is open when the passenger gets on or off.
예를 들면, 운전석에 구비된 도어스위치의 조작에 의해 작동되는 마그네틱밸브를 매개로 오일이 실린더로 유·출입 되면서 당겨지거나 밀어져 개·폐 작동되는 접이식 도어(10)는 도 1에 도시된 바와 같이 승객이 승하차할 수 있도록 서로 단차진 제 1·2발판(12,13)이 마련된 출입구 부위(예를 들어, 상기 제 2발판(13)의 수직면)에는 물체의 존재 여부를 감지하는 포토센서(11)가 구비되어 있고 이에 따라, 승객이 승하차하는 동안 포토센서(11)에 의해 승객이 감지되면, 그 감지된 신호에 의해 가속페달이 동작되지 않도록 되어 있어 개 문 발차가 방지되도록 되어 있다.For example, the folding door 10 which is pulled or pushed as the oil flows into or out of a cylinder via a magnetic valve operated by a door switch provided in a driver's seat is opened and closed, as shown in FIG. 1. A photo sensor for detecting the presence or absence of an object in an entrance area (for example, a vertical surface of the second footrest 13) provided with the first and second footrests 12 and 13 stepped with each other to allow passengers to get on and off. 11) is provided, and if the passenger is detected by the photosensor 11 while the passenger is getting on and off, the accelerator pedal is not operated by the detected signal to prevent opening and closing.
여기서, 상기 도어(10)를 당기거나 미는 실린더에는 도어(10)의 위치를 검출하여 열림과 닫힘을 제어하는 마이크로 스위치(Micro Switch)가 구비됨은 물론이다.Here, the cylinder for pulling or pushing the door 10 is provided with a micro switch for detecting the position of the door 10 to control the opening and closing.
또한, 이와 같이 많은 승객을 태우고 운행하는 버스의 경우에는 안전 장치로서 포토센서(11)이외에도 주행중인 버스에서 승객이 비정상적으로 열린 도어(10)로 떨어져 사고가 나거나 또는 탑승중이거나 하차중인 승객이 있음에도 불구하고 닫히는 경우를 방지하기 도어(10)의 위치에 따른 상태를 감지하는 프린지스위치(Fringe Switch)가 구비되는데, 이 프린지스위치(Fringe Switch)는 도어(10)내에 구비되어 도어(10)의 흔들림 충격을 감지함은 물론 도어(10)와 차체 패널간의 기밀을 유지하는 웨더스트립이 도어(10)에 밀착되는 압력을 감지하게 된다.In addition, in the case of a bus that carries a large number of passengers in this way, as a safety device, even if there are passengers who are in an accident, boarding or getting off from the bus that is running, other than the photo sensor 11, the passenger may be abnormally opened on the door 10. In order to prevent it from closing, a fringe switch (Fringe Switch) for detecting a state according to the position of the door 10 is provided, and the fringe switch is provided in the door 10 to shake the door 10. As well as detecting the shock, the weather strip for maintaining the airtight between the door 10 and the vehicle body panel detects the pressure in close contact with the door (10).
그러나, 이와 같이 포토센서(11)는 자체적으로 물체의 존재여부를 감지함과 더불어 상기 도어스위치와 프린지스위치 및 마이크로스위치등의 조작 신호를 감지해 전반적인 도어(10)의 개·폐작동을 제어하게 되지만, 상기 포토센서(11)의 제어로직이 민감하여 만약, 도어(10)를 닫고 주행중 포토센서(11)가 물체를 감지하게 되면 제어로직의 오류로 승객의 하차중임을 인식해 도어(10)를 열고 이에 따라, 도어(10)가 열린 채로 버스가 주행되어 안전사고는 물론 자칫 인명사고를 유발할 수 있는 문제가 있게 된다.However, as described above, the photosensor 11 detects the presence of an object and detects operation signals such as the door switch, the fringe switch, and the micro switch, so as to control the opening / closing operation of the overall door 10. However, since the control logic of the photosensor 11 is sensitive, if the door 10 is closed and the photosensor 11 detects an object while driving, the controller 10 recognizes that the passenger is getting off due to an error of control logic. As a result, the bus is driven while the door 10 is opened, which may cause a safety accident as well as a human accident.
또한, 상기 포토센서(11)의 제어로직은 신호가 입력되는 스위치의 민감한 감지신호에 의한 오류로 인해 오 동작을 발생하게 되는데 즉, 상기 프린지스위치가 도어(10)가 닫히는 도중 도어(10)의 흔들림이나 충격에 민감하게 반응하거나 또는 도어 닫힘 종료시 도어(10)의 프레임과 웨더스트립의 밀착되는 압력에 민감하게 반응해 도어(10)를 여닫거나 또는 도어(10)가 닫힘 후 주행시 도로 요철에 의한 진동에 민감하게 반응하여 포토센서(11)로 신호를 보내게 되면, 상기 포토센서(11)의 제어로직에 의해 도어(10)를 여닫는 현상이 발생되어 안전사고는 물론 자칫 인명사고를 유발할 수 있는 문제가 있게 된다.In addition, the control logic of the photosensor 11 generates a malfunction due to an error due to a sensitive detection signal of the switch to which the signal is input, that is, the fringe switch of the door 10 while the door 10 is closed. Responsive to shaking or impact or when the door is closed, the door 10 is opened or closed due to the unevenness of the frame and the weather strip. When a signal is sent to the photosensor 11 in response to vibration, a phenomenon in which the door 10 is opened and closed by the control logic of the photosensor 11 may cause a safety accident as well as a human accident. There is a problem.
이와 같은 도어(10)의 비정상적인 작동은 대부분이 안전장치를 작동시키기 위한 신호를 발생하는 포토센서(11)의 제어로직이 오류를 발생하는 것으로 이에 대한 개선이 시급한 실정임은 물론이다.Such abnormal operation of the door 10 is a control logic of the photosensor 11, which generates a signal for operating the safety device in most cases is an error that is an urgent need for improvement.
이에 본 발명은 상기와 같은 점을 감안하여 발명된 것으로, 안전장치를 작동시키기 위한 신호를 발생하는 포토센서의 제어로직에 예기치 못한 상황에 대한 대응 간격과 작동의 판단이 되는 스위치들의 입력신호를 서로 비교·판단해 제어신호를 발생시켜 주행중인 버스의 도어 열림을 방지함에 그 목적이 있다.Accordingly, the present invention has been made in view of the above, and the control logic of the photosensor for generating a signal for operating the safety device has a corresponding interval for an unexpected situation and input signals of switches that are determined to be operated. The purpose is to prevent the door opening of the bus being driven by comparing and judging to generate a control signal.
상기와 같은 목적을 달성하기 위한 본 발명은, 도어를 열기위해 온된 도어스위치의 오프신호에 따라 도어를 닫기 전 포토센서를 통한 물체의 존재가 감지되면, 경고음을 발생한 후 도어를 개·폐하는 실린더를 조작하는 마이크로스위치와 실린더 작동용 마그네틱밸브를 온상태로 전환해 도어의 개방상태를 유지하고, 이후 도어스위치의 오프시간이 설정시간을 초과할 때 외부요인에 의해 마이크로스위치를 온상태로 전환되면 경고음의 발생과 함께 포토센서의 물체 감시·인식기능을 오프시킴과 더불어 실린더 작동용 마그네틱밸브의 제어 신호에 의해서만 도어를 열 수 있도록 해 상기 포토센서의 물체 감지 신호에 의한 주행중 도어의 열림을 방지하도록 되는 것을 특징으로 한다.The present invention for achieving the above object, when the presence of the object through the photosensor before closing the door according to the off signal of the door switch to open the door, the cylinder to open and close the door after generating a warning sound Turn on the micro switch to operate the cylinder and the magnetic valve for cylinder operation to keep the door open.Afterwards, when the off time of the door switch exceeds the set time, the micro switch is turned on by external factors. In addition to turning off the object monitoring and recognition function of the photo sensor along with the alarm sound, the door can be opened only by the control signal of the magnetic valve for cylinder operation to prevent the door from being opened by the object detection signal of the photo sensor. It is characterized by.

도 2는 본 발명에 따른 버스 도어의 안전 개폐방법을 나타낸 순서도를 도시한 것인바, 본 발명은 운전자가 도어스위치를 온(On)시켜 작동되는 마그네틱밸브를 통해 실린더가 도어를 완전히 열 때 도어의 위치에 따라 마이크로스위치가 온(On)되어 포토센서가 물체를 감지해 물체의 여부에 따라 도어의 개·폐상태를 제어하게 된다.Figure 2 shows a flow chart illustrating a safe opening and closing method of the bus door according to the present invention, the present invention is the driver of the door when the cylinder fully opens the door through the magnetic valve operated by turning on the door switch (On) The microswitch is turned on according to the position, and the photosensor detects the object and controls the opening / closing state of the door depending on the object.
이어, 상기 도어(10)가 열린 상태에서 도어스위치가 오프(Off)상태인지 여부를 지속적으로 체크한 후, 상기 도어스위치의 오프(Off)신호에 따라 도어(10)를 닫기 전 포토센서(11)를 통해 물체의 존재 여부를 감지하게 된다.Subsequently, after continuously checking whether the door switch is in an off state while the door 10 is open, the photosensor 11 before closing the door 10 according to the off signal of the door switch. ) Detects the presence of an object.
이어, 상기 포토센서(11)에 의해 물체가 인식되면 운전자나 승객이 알 수 있도록 경고음을 발생시킨 후, 이어 도어(10)를 개·폐하는 실린더를 조작하는 마이크로스위치의 온(On)상태를 확인해 온(On)일 때 실린더 작동용 마그네틱밸브를 온(On)상태로 전환해 도어(10)를 닫지 않고 열린 상태로 유지시켜 준다.Subsequently, when the object is recognized by the photosensor 11, a warning sound is generated so that a driver or a passenger can know, and then the on state of the microswitch for operating the cylinder for opening and closing the ear door 10 is set. When it is checked, the magnetic valve for cylinder operation is turned on to keep the door 10 open without closing it.
한편, 상기 포토센서(11)를 통해 물체의 감지 여부를 다시 확인해 물체가 감지되지 않으면 도어(10)를 닫으면서 동시에 마이크로스위치가 오프된 상태에서 상기 도어스위치의 설정된 오프시간 동안 변화여부를 체크하게 된다.On the other hand, if the object is not detected through the photosensor 11 again to check whether the object is not detected at the same time closing the door 10 while the micro switch is turned off to check whether the change during the set off time of the door switch do.
이어, 상기 도어스위치의 오프(Off)시간이 20초 이상이면서 동시에 차량 진동등과 같은 외부요인에 의해 마이크로스위치가 온(On)상태로 전환되었는지 여부를 감지한 후 만약, 상기 마이크로스위치가 온(On)상태로 전환되었다면 경고음을 발생하면서 포토센서(11)의 물체 감시·인식기능을 오프(Off)시킴과 동시에 실린더 작동용 마그네틱밸브에 의해서만 도어를 열 수 있도록 제어로직의 기능을 제한해 주게 된다.Subsequently, when the off time of the door switch is 20 seconds or more and at the same time, whether the micro switch is turned on by external factors such as a vehicle vibration lamp, the micro switch is turned on. If it is changed to On), alarm sound is generated and object monitoring and recognition function of photo sensor 11 is turned off, and the function of control logic is limited so that the door can be opened only by magnetic valve for cylinder operation. .
이때, 상기 도어스위치의 오프(Off)시간이 20초 이상이면서 동시에 마이크로스위치가 오프(Off)상태를 유지하는 경우에는 정상적인 상태임을 판단하고, 상기 도어스위치가 다시 온(On)되면 도어(10)를 열고 전술한 바와 같이 상황에 따라 포토센서(11)의 물체 인식 신호에 의해 도어를 제어하게 된다.At this time, when the off time of the door switch is 20 seconds or more and at the same time the micro switch maintains the off state, it is determined that the normal state. When the door switch is turned on again, the door 10 As described above, the door is controlled by the object recognition signal of the photosensor 11 as described above.
이상 설명한 바와 같이 본 발명에 의하면, 안전장치를 작동시키기 위한 신호를 발생하는 포토센서의 물체 감지 기능을 도어스위치의 조작조건과 상태에 따라 도어의 제어로직에서 제외시켜 주행중인 상태에서 포토센서에 의한 물체 인식 신호에 따른 도어의 열림을 차단시켜 안전사고는 물론 인명사고의 발생 자체를 완전히 방지할 수 있는 효과가 있게 된다.As described above, according to the present invention, the object detection function of the photosensor which generates a signal for operating the safety device is excluded from the control logic of the door according to the operation condition and state of the door switch. By blocking the opening of the door according to the object recognition signal it is possible to completely prevent the occurrence of safety accidents as well as the accident itself.
