또한, 상기 제어부는 상기 움직임 감지 신호에 의해 움직이는 물체가 감지되지 않을 때, 상기 이전 도로 표지병 구동 장치로부터의 상기 구동 식별 신호의 값을 이용하여 상기 구동 식별 신호가 인가되었는지를 판정하고, 상기 이전 도로 표지병 구동 장치로부터 상기 구동 식별 신호가 인가된 상태로 판정되면, 상기 램프 구동 신호의 상태를 점등 상태로 변환하여 상기 램프부를 점등시키며 상기 이전 도로 표지병 구동 장치로부터의 상기 구동 식별 신호의 상태를 판정하여, 판정된 상기 구동 식별 신호의 상태에 따라 정해진 상태의 구동 식별 신호를 다음 도로 표지병 구동 장치로 출력하고, 상기 구동 식별 신호의 상태가 초기 상태로 판정되어 상기 구동 식별 신호가 인가되지 않은 상태로 판정되면, 상기 램프부를 소등시킨다.Further, when the moving object is not detected by the motion detection signal, the controller determines whether the driving identification signal is applied using the value of the driving identification signal from the previous road marker bottle driving device, and the previous road If it is determined that the drive identification signal is applied from the marker bottle driving device, the state of the lamp driving signal is converted to a lit state to light up the lamp unit, and the state of the drive identification signal from the previous road marker bottle driving device is determined. And outputting the driving identification signal having a predetermined state to the next road marker bottle driving apparatus according to the determined state of the driving identification signal, and determining the state of the driving identification signal as the initial state so that the driving identification signal is not applied. The lamp unit is turned off.

The driving speed of the bicycle is based on a time difference between a time point at which a motion is detected by the motion detection signal and a time point at which the previous road marker bottle driving identification signal is applied and a distance between two adjacent road marker bottles each provided with the road marker bottle driving device. Can be calculated.

The state of the driving identification signal may be determined using the value of the identification signal.
상기 n개의 값 각각은 상기 구동 식별 신호의 상기 초기값과 상이한 것이 바람직하다.Each of the n values is preferably different from the initial value of the drive identification signal.

According to another aspect of the present invention, there is provided a method of driving a road sign bottle, which determines whether a moving object is detected by reading the motion detection signal, and when the moving object is detected, converts the state of the lamp driving signal into a lit state to the lamp unit.

이러한 특징에 따르면, 물체의 움직임을 감지하는 움직임 감지부가 RF 방식의 움직임 감지부이므로, 물체의 움직임 감지 동작의 신뢰성이 향상되고, 움직임 감지부의 수명이 늘어나, 도로 표지병의 신뢰성과 수명이 증가한다.According to this feature, since the motion detection unit for detecting the movement of the object is an RF type motion detection unit, the reliability of the movement detection operation of the object is improved, the lifespan of the motion detection unit is increased, and the reliability and lifespan of the road sign bottle are increased.

As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention. In the drawings, parts irrelevant to the description are omitted in order to clearly describe the present invention, and like reference numerals designate like parts throughout the specification.
그러면 첨부한 도면을 참고로 하여 본 발명의 한 실시예에 따른 도로 표지병 구동 장치 및 방법에 대하여 설명한다.Next, a road sign bottle driving apparatus and method according to an embodiment of the present invention will be described with reference to the accompanying drawings.
먼저, 도 1 내지 도 3를 참고로 하여 본 발명의 한 실시예에 따른 도로 표지병 및 그 구동 장치에 대하여 상세하게 설명한다.First, a road sign bottle and a driving device thereof according to an embodiment of the present invention will be described in detail with reference to FIGS. 1 to 3.
도 1에 도시한 것처럼, 본 발명의 한 실시예에 따른 도로 표지병(1)은 사각형 형상의 본체(100)를 갖고 있고, 본체(100)의 가운데 부분에는 위로 돌출된 돌출부(110)를 갖고 있다. 도 1에서 돌출부(110)의 평면 형상은 본체(100)의 평면 형상과 동일한 사각형 형상을 갖고 있지만, 이에 한정되지 않고 원형이나 타원형과 같은 다양한 평면 형상을 가질 수 있다. 따라서, 본체(110)의 평면 형상과 돌출부(110)의 평면 형상은 서로 상이할 수 있다. 또한, 본체(100)의 평면 형상 역시 설치 위치나 미관상의 이유 등으로 다양한 형상으로 변경 가능하다.As shown in FIG. 1, the road marking bottle 1 according to an embodiment of the present invention has a main body 100 having a rectangular shape, and has a protrusion 110 protruding upward from the center portion of the main body 100. . In FIG. 1, the planar shape of the protrusion 110 has the same rectangular shape as the planar shape of the main body 100, but is not limited thereto and may have various planar shapes such as a circle or an ellipse. Therefore, the planar shape of the main body 110 and the planar shape of the protrusion 110 may be different from each other. In addition, the planar shape of the main body 100 can also be changed into various shapes for reasons such as an installation position or aesthetic appearance.
이때, 본체(100)와 돌출부(110)의 상부면은 모두 평탄면을 갖고 있고, 돌출부(110)의 상부는 빛이 투과되는 유리나 플라스틱과 같은 투명한 재료로 이루어져 있다.In this case, both the main body 100 and the upper surface of the protrusion 110 have a flat surface, the upper portion of the protrusion 110 is made of a transparent material such as glass or plastic through which light is transmitted.
돌출부(110)의 내부에는 자동차나 자전거와 같은 물체의 움직임을 감지하는 움직임 감지부, 발광 다이오드(light emitter diode, LED)와 같은 적어도 하나의 램프 및 램프의 점등 및 소등을 제어하는 제어부 등을 구비한 도로 표지병 구동 장치가 내장되어 있어, 도로 표지병 구동 장치에서 인가되는 신호에 따라 도로 표지병의 점등 및 소등 상태가 제어된다.The protrusion 110 includes a motion detector for detecting a movement of an object such as a car or a bicycle, at least one lamp such as a light emitter diode (LED), and a controller for controlling the lighting and turning off of the lamp. One road beacon driving device is built in, so that the on and off state of the road beacon is controlled according to a signal applied from the road beacon bottle driving device.
이러한 도로 표지병(1)은 자전거 도로나 자동차 도로, 또는 터널 등에 설치되어 자전거나 차량의 주행 방향에 따라 자동으로 점등되어 운전자에게 주행 방향을 알려준다.The road marker bottle 1 is installed on a bicycle road, an automobile road, a tunnel, or the like, and automatically lights up according to the driving direction of the bicycle or the vehicle to inform the driver of the driving direction.
도로 표지병(1)이 자전거 도로에 설치된 예를 도 2에 도시하였지만, 이미 설명한 것처럼, 본 발명의 한 실시예에 따른 도로 표지병(1)은 자동차가 주행하는 도로나 터널 등에 자동차의 주행 방향을 따라 나란히 설치될 수 있다.2 shows an example in which the road marker bottle 1 is installed on a bicycle road, but as described above, the road marker bottle 1 according to an embodiment of the present invention is arranged along a driving direction of a vehicle such as a road or a tunnel on which a vehicle runs. Can be installed side by side.
이하에서, 도로 표지병(1)은 자전거 도로에 설치되어 있고, 자전거의 주행 상태에 따라 도로 표지병(1)의 점등 상태를 제어하는 도로 표지병 구동 장치에 대하여 설명한다. In the following, the road marker bottle 1 is installed on the bicycle road, and the road marker bottle driving device for controlling the lighting state of the road marker bottle 1 in accordance with the running state of the bicycle will be described.
따라서, 도로 표지병(1)은 자전거 도로의 가장 자리나 중앙 부분에 자전거 도로를 따라서 일렬로 복수 개(예를 들어, m개)가 설치되어 있고, 각 도로 표지병(1)을 구동하는 도로 표지병 구동 장치(10)는 각 도로 표지병(1)마다 설치되어 있다. 이때, 인접한 두 도로 표지병(1)은 정해진 간격으로 이격되어 있다.Therefore, the road marker bottle 1 is provided with a plurality (for example m) in a line along the bicycle road at the edge or the central portion of the bicycle road, driving the road marker bottle driving each road marker bottle 1 The apparatus 10 is provided for each road marking bottle 1. At this time, two adjacent road marker bottles 1 are spaced at predetermined intervals.
m개의 도로 표지병 구동 장치(10)는 서로 동일한 구조를 갖고 있고, 인접한 도로 표지병 구동 장치(10)는 도 3에 도시한 것처럼 서로 연결되어있다. The m road marker bottle driving apparatuses 10 have the same structure, and the adjacent road marker bottle driving apparatuses 10 are connected to each other as shown in FIG.
도 4에 참고로 하여, m번째 도로 표지병 구동 장치(10)의 구조를 설명한다.With reference to FIG. 4, the structure of the mth road marker bottle drive apparatus 10 is demonstrated.
도로 표지병 구동 장치(10)는 자전거의 움직임을 감지하여 해당 상태의 움직임 감지 신호를 출력하는 움직임 감지부(11), 움직임 감지부(11)와 바로 이전 즉 (m-1)번째에 위치한 도로 표지병 구동 장치(이하, '이전 도로 표지병 구동 장치'라 함)(10)에 연결되어 있고, 움직임 감지부(101)로부터 움직임 감지 신호와 이전 도로 표지병 구동 장치(10)에서 출력되는 구동 식별 신호(ID)를 입력 받아 해당 상태의 램프 구동 신호(LDS)와 해당 상태의 구동 식별 신호(ID)를 출력하는 제어부(12), 그리고 제어부(12)와 연결되어 있고, 제어부(12)로부터 출력되는 램프 구동 신호(LDS)의 상태에 따라 점등되거나 소등되는 램프부(13)를 구비한다.The road marker bottle driving device 10 detects the movement of the bicycle and outputs a motion detection signal of a corresponding state, and the road marker bottle immediately before the (m-1) th motion detector 11 and the motion detector 11. A drive identification signal (ID), which is connected to a driving device (hereinafter, referred to as a 'previous road sign bottle driving device') 10 and output from a motion detection unit 101 and a previous road sign bottle driving device 10. ) Is connected to the control unit 12 and the control unit 12 to output the lamp driving signal LDS of the state and the drive identification signal ID of the state, and the lamp driving output from the control unit 12. The lamp unit 13 is turned on or off in accordance with the state of the signal LDS.
본 실시예에서, 제어부(12)에서 출력되는 구동 식별 신호(ID)는 바로 이후에 즉, (m+1)번째에 위치한 도로 표지병 구동 장치(이하, '다음 도로 표지병 구동 장치'라 함)(10)로 입력된다.In the present embodiment, the drive identification signal ID output from the control unit 12 is immediately after, that is, the road marker bottle driving device (hereinafter, referred to as 'next road marker bottle driving device') located at (m + 1) th ( 10) is entered.
움직임 감지부(11)는 RF(radio frequency) 방식의 움직임 감지부로서, 본 실시예의 움직임 감지부(11)에서 사용된 분배 주파수는 약 10.525GHz이거나 약 24.15GHz일 수 있다.The motion detector 11 is a radio frequency (RF) type motion detector, and the distribution frequency used by the motion detector 11 of the present embodiment may be about 10.525 GHz or about 24.15 GHz.
이처럼, RF 방식의 움직임 감지부(11)를 사용함에 따라 주변의 온도, 습도, 먼지, 햇빛, 또는 소리 등에 관계없이 저전거와 같은 물체의 움직임이 있을 때만 작동하여, 움직임 감지부(11)는 자전거의 움직임을 정확하게 감지한다. As such, by using the RF method of the motion detection unit 11 operates only when there is movement of an object such as a low bike regardless of the surrounding temperature, humidity, dust, sunlight, or sound, the motion detection unit 11 is a bicycle To accurately detect movement.
RF 방식의 움직임 감지부(11)는 적외선을 이용한 적외선 방식의 움직임 감지부보다 약 5배가 넓은 대략 20m의 감지 거리를 갖고 있어, 적외선 방식의 움직임 감지부보다 감지 범위가 넓어 주행하는 자전거의 감지 동작이 신속하게 이루어진다.The RF type motion detection unit 11 has a sensing distance of approximately 20 m, which is about 5 times wider than the infrared type motion detection unit using infrared rays, and thus detects a bicycle operating with a wider detection range than the infrared type motion detection unit. This is done quickly.
또한, 적외선 방식의 움직임 감지부의 경우, 적외선을 발사하기 위해 움직임 감지부는 렌즈를 구비하여 움직임 감지부의 표면은 렌즈 형상을 갖고 있고, 이로 인해 적외선의 발사 방향의 범위가 정해져 있다. In addition, in the case of the infrared motion detection unit, the motion detection unit includes a lens to emit infrared light, and the surface of the motion detection unit has a lens shape, and thus the range of the infrared emission direction is determined.
하지만, 본 실시예에 따른 RF 방식의 움직임 감지부(11)는 움직임 감지부(11)를 중심으로 전 방위에 걸쳐 감지 신호가 출력되므로, 자전거의 움직임 감지 범위가 적외선 방식의 움직임 감지부보다 넓다.However, since the motion detection unit 11 of the RF method according to the present embodiment outputs a detection signal over the entire direction around the motion detection unit 11, the motion detection range of the bicycle is wider than that of the infrared type motion detection unit. .
또한, 위에 기재한 것처럼, 적외선 방식의 움직임 감지부는 렌즈를 갖고 있으므로, 자전거 도로의 표면 위로 렌즈의 표면이 돌출되어 있다. 이로 인해, 자전거나 사람 등에 의해 돌출된 렌즈가 손상되는 문제가 발생한다.In addition, as described above, since the infrared motion detecting unit has a lens, the surface of the lens protrudes above the surface of the bicycle road. For this reason, the problem that the lens which protrudes by a bicycle, a person, etc. is damaged arises.
하지만, 본 실시예에 따른 RF 방식의 움직임 감지부(11)는 렌즈를 구비할 필요가 없으므로, 자전거 도로의 표면 위로 돌출되는 부분이 감소하고 돌출부가 평탄면을 갖고 있으므로, 움직임 감지부(11)의 파손 우려가 감소하여 움직임 감지부(11)의 수명이 증가한다.However, since the motion detecting unit 11 of the RF method according to the present embodiment does not need to include a lens, since the portion protruding over the surface of the bicycle road is reduced and the protrusion has a flat surface, the motion detecting unit 11 The risk of breakage is reduced and the service life of the motion detector 11 is increased.
이러한 움직임 감지부(11)는 설치된 자전거 도로에 움직이는 자전거가 감지되면 해당 상태의 움직임 감지 신호를 제어부(12)로 출력한다.The motion detector 11 outputs a motion detection signal of a corresponding state to the controller 12 when a moving bicycle is detected on the installed bicycle road.
따라서, 제어부(12)는 움직임 감지 신호의 상태를 판정하여, 자전거가 감지되었는지의 여부를 판정하고, 움직이는 물체, 예를 들어, 움직이는 자전거의 감지 상태와 이전 도로 표지병 구동 장치(10)로부터 인가되는 구동 식별 신호(ID)에 따라 램프부(13)의 점등 동작과 다음 도로 표지병 구동 장치(10)로 출력되는 구동 식별 신호(ID)의 상태를 제어한다. 이때, 제어부(12)는 필요에 따라 이전 도로 표지병 구동 장치(10)에서 인가되는 구동 식별 신호(ID)를 저장하기 위한 메모리(memory) 등을 구비할 수 있다. Accordingly, the control unit 12 determines the state of the motion detection signal, determines whether the bicycle is detected, and is applied from the detection state of the moving object, for example, the moving bicycle, and the previous road sign bottle driving device 10. The lighting operation of the lamp unit 13 and the state of the drive identification signal ID output to the next road sign bottle driving device 10 are controlled in accordance with the drive identification signal ID. In this case, the controller 12 may include a memory for storing the driving identification signal ID applied from the previous road sign bottle driving device 10 as necessary.
본 예에서, 구동 식별 신호(ID)는 현재 도로 표지병 구동 장치(10)에서 감지된 자전거의 주행 속도에 기초하여, 자전거의 주행 방향을 따라 현재 도로 표지병 구동 장치(예를 들어, m번째의 도로 표지병 구동 장치)(10) 이후에 배치된 복수의 표지병 구동 장치(10)에 의해 각각 순차적으로 점등되는 램프부(10)의 개수를 제어하기 위한 것이다.In this example, the driving identification signal ID is based on the driving speed of the bicycle currently detected by the road marker bottle driving device 10, and the current road marker bottle driving device (eg, the m-th road) along the driving direction of the bicycle. It is for controlling the number of lamp units 10 sequentially lit by a plurality of cover bottle drive devices 10 arranged after the cover bottle drive device 10).
따라서, 본 실시예에서, 자전거의 주행 속도에 따라 자동차의 주행 방향을 알려주는 도로 표지병(1)의 점등 개수는 달라진다. 예를 들어, 자동차의 주행 속도가 증가할 경우, 점등되는 도로 표지병(1)의 점등 개수는 증가할 수 있다.Therefore, in the present embodiment, the number of lighting of the road sign bottle 1 informing the driving direction of the vehicle varies depending on the running speed of the bicycle. For example, when the running speed of the vehicle increases, the number of lights of the road sign bottle 1 that is turned on may increase.
램프부(13)는 적어도 하나의 발광 다이오드(light emitting diode)와 같은 램프(lamp)를 구비하고 있고, 제어부(12)에서 출력되는 램프 구동 신호(LDS)의 상태에 따라 적어도 하나의 발광 다이오드가 점등되거나 소등된다. 예를 들어, 램프 구동 신호(LDS)의 상태가 점등 상태[예를 들어, 램프 구동 신호(LDS)가 고레벨(high) 상태]일 때 발광 다이오드는 점등되고, 램프 구동 신호(LDS)의 상태가 소등 상태[예를 들어, 램프 구동 신호(LDS)가 저레벨(low) 상태]일 때 발광 다이오드는 소등된다. The lamp unit 13 includes a lamp such as at least one light emitting diode, and at least one light emitting diode may be provided according to a state of the lamp driving signal LDS output from the controller 12. Lights up or goes out For example, when the state of the lamp drive signal LDS is a lit state (for example, the state of the lamp drive signal LDS is a high level), the light emitting diode is turned on, and the state of the lamp drive signal LDS is The light emitting diode is turned off when the lamp is turned off (for example, the lamp driving signal LDS is at a low level).
대안적인 예에서, 램프부(13)는 발광 다이오드 이외의 다양한 램프가 사용될 수 있다.In an alternative example, the lamp unit 13 may be a variety of lamps other than light emitting diodes.
도 5a와 도 5b를 참고로 하여, 이러한 도로 표지병 구동 장치(10)의 동작을 설명한다.5A and 5B, the operation of the road sign bottle driving device 10 will be described.
이미 설명한 것처럼, 서로 연결된 복수의 도로 표지병 구동 장치(10)는 동일한 구조로 이루어져 있어, 서로 동일한 동작을 실행한다.As described above, the plurality of road marker bottle driving apparatuses 10 connected to each other have the same structure, and perform the same operation with each other.
따라서, 이전 도로 표지병 구동 장치[예를 들어, (m-1)번째 도로 표지병 구동장치](10)로부터 구동 식별 신호(ID)를 입력 받고, 다음 도로 표지병 구동 장치[예를 들어, (m+1)번째 도로 표지병 구동장치](10)로 구동 식별 신호(ID)를 출력하는 현재 도로 표지병 구동 장치(예를 들어, m번째 도로 표지병 구동장치)(10)의 동작에 대해서만 설명한다.Therefore, the drive identification signal ID is input from the previous road marker bottle driving device (for example, the (m-1) th road marker bottle driving device) 10, and the next road marker bottle driving device (for example, (m + Only the operation of the current road marker bottle driving device (for example, the m-th road marker bottle driving device) 10 that outputs the drive identification signal ID to the (1) th road marker bottle driving device] 10 will be described.
먼저, 동작에 필요한 전원이 공급되면, 도로 표지병 구동 장치(10)의 제어부(12)는 움직임 감지부(11)로부터 인가되는 움직임 감지 신호를 판독하여(S11), 자전거 도로에서 주행하거나 이동하는 자전거가 존재하는지의 여부를 판정한다(S13).First, when the power required for the operation is supplied, the control unit 12 of the road sign bottle driving device 10 reads the motion detection signal applied from the motion detection unit 11 (S11), the bicycle running or moving on the bicycle road It is determined whether or not there is (S13).
판독된 움직임 감지 신호의 상태가 움직이는 물체, 즉, 자전거가 존재하여 움직임이 감지된 상태로 판단되면, 제어부(12)는 자신과 연결된 램프부(13)를 점등하기 위해 점등 상태의 램프 구동 신호(LDS)를 램프부(13)로 출력한다(S15).When the state of the read motion detection signal is determined to be a moving object, that is, a state in which a movement is detected, the controller 12 may turn on the lamp driving signal in a lit state to turn on the lamp unit 13 connected thereto. LDS) is output to the lamp unit 13 (S15).
따라서, 램프부(13)를 제어부(12)로부터 인가되는 램프 구동 신호(LDS)에 의해 점등되어 자전거의 주행 방향을 알려주게 된다.Therefore, the lamp unit 13 is turned on by the lamp driving signal LDS applied from the control unit 12 to inform the driving direction of the bicycle.
그런 다음, 제어부(12)는 이전 도로 표지병 구동 장치(10)의 제어부로부터로부터 인가되는 구동 식별 신호(ID)를 판독하여(S17), 이전 도로 표지병 구동 장치(10)로부터 구동 식별 신호(ID)가 인가되었는지를 판단한다(S19). Then, the control unit 12 reads the driving identification signal ID applied from the control unit of the previous road sign bottle driving device 10 (S17), and the driving identification signal ID from the previous road sign bottle driving device 10. It is determined whether is authorized (S19).
본 예에서, 제어부(12)는 구동 식별 신호(ID)의 값을 이용하여 구동 식별 신호(ID)의 인가 여부를 판정할 수 있다. In this example, the controller 12 may determine whether the driving identification signal ID is applied using the value of the driving identification signal ID.
예를 들어, 판독된 이전 도로 표지병 구동 장치(10)로부터의 구동 식별 신호(ID)의 값이 초기값, 예를 들어, '000'일 때, 제어부(12)는 이전 도로 표지병 구동 장치(10)로부터의 구동 식별 신호(ID)의 상태를 초기 상태로 판정하여 이전 도로 표지병 구동 장치(10)로부터 구동 식별 신호(ID)가 인가되지 않은 상태로 판정한다.For example, when the read value of the drive identification signal ID from the previous road sign driving device 10 is an initial value, for example, '000', the controller 12 controls the previous road sign driving device 10. The state of the drive identification signal ID from) is determined as an initial state, and it is determined that the drive identification signal ID is not applied from the previous road sign bottle driving device 10.
하지만, 판독된 구동 식별 신호(ID)의 값이 초기값(000)과 다른 값, 예를 들어,'001', 010', 또는 '011'을 가질 때, 제어부(12)는 이전 도로 표지병 구동 장치(10)로부터 구동 식별 신호(ID)가 인가된 상태로 판정할 수 있다.However, when the value of the read driving identification signal ID has a value different from the initial value 000, for example, '001', 010 ', or' 011 ', the controller 12 drives the previous road marker bottle. It may be determined that the driving identification signal ID is applied from the device 10.
이처럼, 이전 도로 표지병 구동 장치(10)로부터의 구동 식별 신호(ID)를 판독하여, 판독된 구동 식별 신호(ID)의 상태가 인가 상태가 아닐 경우, 즉, 판독된 구동 식별 신호(ID)가 초기값을 가져 초기 상태일 때, 제어부(12)는 별도의 제어 동작을 행하지 않고, 단계(S11)로 넘어가 움직임 감지부(11)로부터 인가되는 움직임 감지 신호를 판독한다.In this way, when the driving identification signal ID from the previous road marker bottle driving device 10 is read, and the state of the read driving identification signal ID is not an applied state, that is, the read driving identification signal ID is read. When the initial state is obtained with the initial value, the control unit 12 proceeds to step S11 to read the motion detection signal applied from the motion detection unit 11 without performing a separate control operation.
이로 인해, 움직이는 자전거만 감지되고, 이전 도로 표지병 구동 장치(10)로부터 구동 식별 신호(ID)가 인가된 상태로 판단되지 않을 경우, 현재 도로 표지병 구동 장치(10)에 의해 자전거의 움직임이 감지되었으므로, 현재 도로 표지벼 구동 장치(10)를 구비한 현재 표지 표지병(예를 들어, m번째 도로 표지병)만이 점등되고, 그 이후에 위치한 적어도 하나의 도로 표지병은 점등되지 않는다.For this reason, when only the moving bicycle is detected and the driving identification signal ID is not determined to be applied from the previous road marker bottle driving device 10, since the movement of the bicycle is currently detected by the road marker bottle driving device 10. Only the current marker cover bottle (for example, the m-th road marker bottle) provided with the current road marker rice driving device 10 is turned on, and at least one road marker bottle placed thereafter is not lit.
하지만, 단계(S19)에서 구동 식별 신호(ID)가 인가된 상태로 판정되면, 예를 들어, 판독된 구동 식별 신호(ID)의 값이 초기값이 아닌 다른 값(예, '001', '010' 및 '011'중 하나)을 가질 때, 제어부(12)는 움직임 감지 신호에 의해 움직임이 감지된 시점과 구동 식별 신호(ID)의 인가 판정 시점간의 시간차(ΔT)를 산출한다(S21). 이때, 움직임이 감지된 시점과 구동 식별 신호(ID)의 인가 판정 시점 각각은 제어부(12)의 제어 동작에 의해 타이머(도시하지 않음)에 의해 산출되어 메모리 등에 이미 저장되어 있다. 이때, 타이머는 제어부(12) 내에 또는 외부에 위치할 수 있다.However, if it is determined in step S19 that the driving identification signal ID is applied, for example, the value of the read driving identification signal ID is different from the initial value (for example, '001', ' 010 'and one of' 011 '), the controller 12 calculates a time difference ΔT between the time when the motion is detected by the motion detection signal and the time when the driving identification signal ID is determined to be applied (S21). . At this time, each of the time when the motion is detected and the time of determining whether the driving identification signal ID is applied are calculated by a timer (not shown) by the control operation of the control unit 12 and already stored in the memory or the like. In this case, the timer may be located inside or outside the controller 12.
다음, 제어부(12)는 산출된 시간차(ΔT)를 이용하여 주행중인 자전거의 주행 속도를 산출하고(S23), 산출된 자전거의 주행 속도가 속하는 영역, 예를 들어, 저속인지, 중속인지 또는 고속인지를 판정한다(S25). Next, the control unit 12 calculates the driving speed of the bicycle being driven using the calculated time difference ΔT (S23), and the area to which the calculated driving speed belongs, for example, a low speed, a medium speed, or a high speed. It is determined whether the recognition (S25).
본 예에서, 저속은 자전거의 주행 속도가 15km/h 이하일 경우, 고속은 자전거의 주행 속도가 30km/h 이상일 때, 그리고 중속은 자전거의 주행 속도가 저속과 고속 사이의 속도, 즉 15km/h 초과 내지 30km/h 미만일 때이다.In this example, the low speed means that when the speed of the bicycle is less than 15 km / h, the high speed is when the speed of the bicycle is more than 30 km / h, and the medium speed is the speed between the low speed and the high speed of the bicycle, that is, more than 15 km / h. To less than 30 km / h.
자전거의 주행 속도는 n개의 영역으로 나눠지고, 본 예에서, n개는 3개(예, 저속, 중속 및 고속)이지만, 이는 하나의 예에 불과하고, 산출된 주행 속도가 속하는 영역의 개수는 필요에 따라 가변되며, 각 영역에 포함되는 주행 속도의 범위 역시 가변될 수 있다.The running speed of the bicycle is divided into n areas, and in this example, n pieces are three (eg, low speed, medium speed and high speed), but this is only one example, and the number of areas to which the calculated driving speed belongs is If necessary, the range of the traveling speed included in each area may also vary.
이때, 자전거의 주행 속도는 인접한 두 도로 표지병(1) 간의 거리와 시간차(ΔT)를 이용하여 산출되며, 인접한 두 도로 표지병(1) 간의 거리는 이미 제어부(12)에 저장되어 있다.At this time, the running speed of the bicycle is calculated using the distance between the two adjacent road marker bottles 1 and the time difference ΔT, and the distance between the two adjacent road marker bottles 1 is already stored in the controller 12.
다음, 판정된 자전거의 주행 속도가 저속일 경우, 제어부(12)는 다음 도로 표지병 구동 장치(10)의 제어부로 제1 상태의 구동 식별 신호(ID)를 출력하고(S27), 판정된 자전거의 주행 속도가 중속일 경우, 제어부(12)는 다음 도로 표지병 구동 장치(10)로 제2 상태의 구동 식별 신호(ID)를 출력하며(S29), 판정된 자전거의 주행 속도가 고속일 경우, 제어부(12)는 다음 도로 표지병 구동 장치(10)로 제3 상태의 구동 식별 신호(ID)를 출력한 후(S31), 단계(S11)로 넘어가 움직이는 물체가 존재하는지의 여부를 판정한다.Next, when the determined driving speed of the bicycle is a low speed, the control unit 12 outputs the driving identification signal ID of the first state to the control unit of the next road sign bottle driving device 10 (S27), When the driving speed is a medium speed, the control unit 12 outputs the driving identification signal ID of the second state to the next road sign bottle driving device 10 (S29), and when the determined driving speed of the bicycle is high speed, the control unit 12 After outputting the drive identification signal ID of a 3rd state to the next road marking bottle drive apparatus 10 (S31), it moves to step S11 and determines whether there exists a moving object.
본 예에서, 구동 식별 신호(ID)는 자전거 주행 속도의 영역의 수(n개)와 동일한 수(n개)의 상태를 갖고 있고, 각 상태를 나타내는 구동 식별 신호(ID)의 값은 서로 상이하다. 따라서, 제어부(12)는 판정된 자전거 주행 속도가 속하는 영역에 대응되는 고유의 값을 판정하고, 판정된 값을 다음 도로 표지병 구동 장치(10)의 제어부(12)로 출력되는 구동 식별 번호(ID)의 값으로 정한다.In this example, the drive identification signal ID has the same number (n) states as the number (n) of areas of the bicycle driving speed, and the values of the drive identification signals ID representing each state are different from each other. Do. Therefore, the control part 12 determines the intrinsic value corresponding to the area | region which the determined bicycle driving speed belongs, and drives the drive identification number (ID) outputted to the control part 12 of the next road marker bottle drive apparatus 10. FIG. ).
따라서, 제어부(12)는 판독된 구동 식별 신호(ID)의 값을 이용하여 구동 식별 신호의 상태를 판정하게 된다.Therefore, the control part 12 determines the state of a drive identification signal using the value of the read drive identification signal ID.
이로 인해, 구동 식별 신호(ID)는 초기값을 갖는 초기 상태와 n개의 값을 각각 갖고 있는 n개의 상태를 갖고 있고, 한 예로서, 구동 식별 신호(ID)의 초기값은 '000'일 수 있고, 구동 식별 신호(ID)는 제1 내지 제3 상태를 갖고 있을 수 있다.Thus, the driving identification signal ID has an initial state having an initial value and n states each having n values, and as an example, the initial value of the driving identification signal ID may be '000'. The driving identification signal ID may have first to third states.
한 예로서, 제1 상태의 구동 식별 신호(ID)는 '001'의 값을 갖는 구동 식별 신호(ID)이고, 제2 상태의 구동 식별 신호(ID)는 '010'의 값을 갖는 구동 식별 신호(ID)이며, 제3 상태의 구동 식별 신호(ID)는 '011'의 값을 갖는 구동 식별 신호(ID)일 수 있다.As an example, the drive identification signal ID of the first state is a drive identification signal ID having a value of '001', and the drive identification signal ID of the second state is a drive identification having a value of '010'. The driving ID signal ID of the third state, which is a signal ID, may be a driving identification signal ID having a value of '011'.
본 예에서, n개의 상태 중에서 최소값을 갖는 상태를 최소 상태로 하고 최대값을 갖는 상태를 최대 상태로 하며, 한 예로서, '001'의 값을 갖는 제1 상태가 최소 상태일 수 있고, '011'의 값을 갖는 제3 상태가 최대 상태일 수 있다.In this example, among the n states, the state having the minimum value is the minimum state and the state having the maximum value is the maximum state. As an example, the first state having the value of '001' may be the minimum state, The third state with a value of 011 'may be the maximum state.
본 예에서, 제1 상태의 구동 식별 신호(ID)는 단계(S11)에서 자전거의 움직임 판정을 위해 움직임 감지 신호를 판독한 현재 도로 표지병 구동 장치(10) 바로 이후에 위치한 한 개의 도로 표지병 구동장치(10)의 램프부(13)만을 점등하기 위한 것이고, 제2 상태의 구동 식별 신호(ID)는 현재 도로 표지병 구동 장치(10)에 연속하게 위치한 두 개의 도로 표지병 구동장치(10)의 램프부(13)를 순차적으로 점등하기 위한 것이며, 제3 상태의 구동 식별 신호(ID)는 현재 도로 표지병 구동 장치(10)에 연속하게 위치한 세 개의 도로 표지병 구동장치(10)의 램프부(13)를 순차적으로 점등하기 위한 것이다.In this example, the driving identification signal ID of the first state is one road beacon driving device located immediately after the current road beacon driving device 10 that reads the motion detection signal for determining the movement of the bicycle in step S11. The lamp unit 13 is for lighting only the lamp unit 13, and the driving identification signal ID of the second state is the lamp unit of the two road marker bottle driving apparatuses 10 continuously positioned at the road marker bottle driving apparatus 10 at present. The driving identification signal ID of the third state turns on the lamp unit 13 of the three road marker bottle driving apparatuses 10 continuously located at the current road marker bottle driving apparatus 10. It is to light up sequentially.
따라서, 움직이는 자전거의 감지에 의해 현재 도로 표지병 구동 장치(10)의 램프부(13)를 점등한 후, 현재 도로 표지병 구동 장치(10)의 제어부(12)는 자전거의 주행 속도에 따라 현재 도로 표지병 구동 장치(10) 이후에 위치한 적어도 하나의 도로 표지병 구동 장치(10)의 램프부(1)를 점등시킨다.Therefore, after the lamp unit 13 of the current road marker bottle driving device 10 is turned on by detecting the moving bicycle, the controller 12 of the current road marker bottle driving device 10 is currently driven by the road speed of the bicycle. The lamp unit 1 of the at least one road marking bottle driving device 10 located after the driving device 10 is turned on.
이로 인해, 구동 식별 신호(ID)의 상태에 따라, 현재 도로 표지병 구동 장치(10)를 구비한 현재 도로 표지병(1)뿐만 아니라 현재 도로 표지병(1) 이후에 위치한 적어도 하나의 도로 표지병(1)이 순차적으로 점등되면, 순차적으로 점등되는 도로 표지병(1)의 점등 개수는 자전거의 주행 속도에 따라 달라진다. For this reason, according to the state of the drive identification signal ID, not only the current road marking bottle 1 equipped with the current road marking bottle driving device 10 but also the at least one road marking bottle 1 located after the present road marking bottle 1. When the lights are sequentially turned on, the number of lights of the road sign bottles 1 which are turned on sequentially depends on the running speed of the bicycle.
또한, 본 예에서, 각 상태의 구동 식별 신호(ID)에 따라 순차적으로 점등되는 도로 표지병(1)의 개수는 1 내지 3이지만, 이에 한정되지 않고 각 상태에 따라 순차적으로 점등되는 도로 표지병(1)의 개수는 필요에 따라 가변될 수 있다. 추가로, 각 상태에 따른 구동 식별 신호(ID)의 값이나 신호의 비트 수 역시 필요에 따라 달라진다.In addition, in this example, the number of road marker bottles 1 which are sequentially lighted in accordance with the driving identification signal ID of each state is 1 to 3, but is not limited thereto, and the road marker bottles 1 which are sequentially lit according to each state. The number of h) may vary as needed. In addition, the value of the drive identification signal ID or the number of bits of the signal according to each state also varies as necessary.
본 예의 경우, 단계(S27, S29 또는 S31)에서 판정된 구동 식별 신호(ID)의 상태는 단계(S19)에서 인가된 이전 도로 표지병 구동 장치(10)로부터의 구동 식별 신호(ID)의 상태에 무관하게 현재 자전거의 주행 속도에 따라 재산출되어 출력된다. 따라서, 현재 도로 표지병 구동 장치(10)에 의해 판정된 자전거의 주행 상태에 따라서, 자전거의 주행 방향을 따라 순차적으로 점등되는 도로 표지병(1)의 개수가 달라지므로 자전거 운전자의 신뢰도와 자전거 주행의 안정성이 향상된다.In this example, the state of the drive identification signal ID determined in step S27, S29 or S31 is in accordance with the state of the drive identification signal ID from the previous road marker bottle driving device 10 applied in step S19. Regardless of the current bicycle speed, it is recalculated and output. Therefore, since the number of road marker bottles 1 which are sequentially lighted along the driving direction of the bicycle varies according to the driving state of the bicycle currently determined by the road marker bottle driving device 10, the reliability of the bicycle driver and the stability of the bicycle driving. This is improved.
하지만, 단계(S13)에서, 자전거 도로에서 주행하거나 이동하는 자전거가 존재하지 않은 상태로 판정되면, 제어부(12)는 이전 도로 표지병 구동 장치(10)의 제어부로부터의 구동 식별 신호(ID)를 판독하여(S33), 이전 도로 표지병 구동 장치(10)로부터 구동 식별 신호(ID)가 인가되었는지를 판정한다(S35).However, if it is determined in step S13 that there is no bicycle running or moving on the bicycle road, the controller 12 reads the drive identification signal ID from the controller of the previous road marker bottle driving device 10. (S33), it is determined whether the drive identification signal ID has been applied from the previous road sign bottle driving device 10 (S35).
단계(S35)에서, 구동 식별 신호(ID)가 인가된 상태로 판정되면 점등 상태의 램프 구동 신호(LDS)를 램프부(13)로 출력하여 램프부(13)를 점등하고, 구동 식별 신호(ID)의 상태를 판정한다(S39). In step S35, when it is determined that the driving identification signal ID is applied, the lamp driving signal LDS in the lit state is output to the lamp unit 13 to light up the lamp unit 13, and the driving identification signal ( ID) status is determined (S39).
하지만, 단계(S35)에서, 이전 도로 표지병 구동 장치(10)로부터 구동 식별 신호(ID)가 인가되지 않은 상태로 판단되면, 제어부(12)는 단계(S11)로 넘어가 자전거 도로에 주행하거나 움직이는 자전거가 존재하는지의 여부를 판단한다. However, if it is determined in step S35 that the driving identification signal ID is not applied from the previous road marker bottle driving device 10, the controller 12 proceeds to step S11 to drive or move on a bicycle road. Determine whether or not there is.
이로 인해, 움직임 감지부(11)로부터 움직이는 자전거가 감지되지 않고 이전 도로 표지병 구동 장치(10)로부터 구동 식별 신호(ID)가 인가되지 않을 경우, 제어부(12)는 램프 구동 신호(LDS)의 상태를 점등 상태로 변경하지 않고 소등 상태로 유지하므로, 램프부(12)는 소등 상태를 유지한다. 따라서, 현재 도로 표지병(1)뿐만 아니라 현재 도로 표지병(1) 이후에 위치한 적어도 하나의 도로 표지병(1)은 점등되지 않고 소등된다. Therefore, when the bicycle moving from the motion detecting unit 11 is not detected and the driving identification signal ID is not applied from the previous road sign bottle driving device 10, the controller 12 is in a state of the lamp driving signal LDS. The lamp unit 12 maintains an unlit state because it is kept unlit without changing to a lit state. Therefore, not only the current road marking bottle 1 but also the at least one road marking bottle 1 positioned after the current road marking bottle 1 is turned off without being lit.
이때, 이전 도로 표지병 구동 장치(10)로부터 구동 식별 신호(ID)가 인가되었는지의 여부는 이미 단계(19)에서 설명한 것처럼, 제어부(12)로 입력되는 구동 식별 신호(ID)의 값을 판독한 후, 판독된 구동 식별 신호(ID)의 값에 따라 구동 식별 신호(ID)의 인가 여부를 판정한다.  At this time, whether or not the drive identification signal ID has been applied from the previous road sign bottle driving device 10 has already read the value of the drive identification signal ID input to the controller 12, as described in step 19. Thereafter, it is determined whether or not the driving identification signal ID is applied in accordance with the value of the read driving identification signal ID.
이미 설명한 것처럼, 판독된 구동 식별 신호(ID)의 값이 초기값인'000'일 때 구동 식별 신호(ID)는 초기 상태이므로, 제어부(12)는 이전 도로 표지병 구동 장치(10)로부터 인가되지 않은 상태로 판정하고, 판독된 구동 식별 신호(ID)의 값이 초기값이 아니고 n개 중 하나의 상태의 나타내는 값(예, '001', '010'및 '011' 중 하나)일 때, 제어부(12)는 구동 식별 신호(ID)가 이전 도로 표지병 구동 장치(10)로부터 인가된 상태로 판정한다.As described above, since the driving identification signal ID is in an initial state when the read driving identification signal ID has an initial value of '000', the controller 12 is not applied from the previous road sign bottle driving apparatus 10. Is determined, and the value of the read driving identification signal ID is not an initial value and is a value representing one of n states (for example, one of '001', '010' and '011'). The control unit 12 determines that the driving identification signal ID has been applied from the previous road sign bottle driving device 10.
단계(S39, S41)에서 판정된 구동 식별 신호(ID)의 상태가 최소 상태인 제1 상태일 때, 제어부(12)는 다음 도로 표지병 구동 장치(10)의 제어부로 인가되는 구동 식별 신호(ID)의 값을 변경하지 않고 초기값으로 유지한다(S43).When the state of the drive identification signal ID determined in steps S39 and S41 is the first state which is the minimum state, the control unit 12 applies the drive identification signal ID applied to the control unit of the next road sign bottle driving device 10. ) Is maintained at the initial value without changing the value ().
하지만, 단계(S39, S41)에서 판정된 구동 식별 신호(ID)의 상태가 최소 상태가 아닐 경우, 제어부(12)는 판정된 구동 식별 신호(ID)의 상태의 바로 이전 상태의 값으로 다음 도로 표지병 구동 장치(10)의 제어부로 인가되는 구동 식별 신호(ID)의 값을 정하여, 다음 도로 표지병 구동 장치(10)의 제어부로 출력한다.However, when the state of the drive identification signal ID determined in the steps S39 and S41 is not the minimum state, the control unit 12 returns the next road to the value of the state immediately before the state of the determined drive identification signal ID. The value of the drive identification signal ID applied to the control unit of the beacon bottle driving device 10 is determined, and output to the control unit of the next road beacon bottle driving device 10.
따라서, 단계(S41)에서, 판정된 구동 식별 신호(ID)의 상태가 제2 상태일 때, 제어부(12)는 제1 상태의 구동 식별 신호(ID)를 다음 도로 표지병 구동 장치(10)의 제어부로 출력하고(S45), 판정된 구동 식별 신호(ID)의 상태가 최대 상태인 제3 상태일 때, 제어부(12)는 제2 상태의 구동 식별 신호(ID)를 다음 도로 표지병 구동 장치(10)의 제어부로 출력한다(S47). 그런 다음, 제어부(14)는 단계(S11)로 넘어가 움직이는 물체, 즉, 자전거가 존재하는지 감지한다.Therefore, in step S41, when the determined state of the drive identification signal ID is the second state, the control unit 12 transmits the drive identification signal ID of the first state to the next road sign bottle driving device 10. The controller 12 outputs the driving identification signal ID of the second state to the next road marker bottle driving device (S45), when the determined state of the driving identification signal ID is the third state in the maximum state. Output to the control unit of 10) (S47). Then, the controller 14 proceeds to step S11 to detect whether there is a moving object, that is, a bicycle.
따라서, 비록 현재 도로 표지병 구동 장치(10)에서 움직이거나 주행중인 자전거는 감지되지 않았지만, 이전 도로 표지병 구동 장치(10)의 제어부로부터 출력되는 구동 식별 신호(ID)에 의해 정해진 개수만큼 이후의 도로 표지병 구동 장치(10)의 램프부(13)가 순차적으로 점등된다.Therefore, although the bicycle moving or driving in the road marker bottle driving device 10 is not detected at present, the road marker bottle as determined by the drive identification signal ID output from the control unit of the previous road marker bottle driving device 10 is later. The lamp unit 13 of the drive device 10 is sequentially turned on.
이러한 본 실시예에 따라, 자전거의 주행 속도에 따라서 자전거의 주행 방향으로 정해진 간격을 두고 위치한 복수의 도로 표지병(1)의 점등 개수는 단지 한 개가 아니라 복수의 램프가 순차적으로 점등하게 된다. According to this embodiment, the number of lighting of the plurality of road marker bottles 1 positioned at predetermined intervals in the driving direction of the bicycle according to the traveling speed of the bicycle is not just one, but a plurality of lamps are sequentially turned on.
