Description
본 고안은 휠로더와 같은 중장비의 후방에 설치되어 중장비의 후진시 후방에 있는 장애물과 중장비의 후측부와의 거리를 감지하여서 운전자가 경각심을 가지도록 하는 후방 장애물 감지장치에 관한 것이다.The present invention relates to a rear obstacle detecting device installed at the rear of heavy equipment such as a wheel loader to sense the distance between the obstacle at the rear of the heavy equipment and the rear side of the heavy equipment so that the driver has an alert.
일반적으로 휠로더와 같은 건설중장비를 후진할때 중장비의 후방에 있는 장애물을 인식하기 위하여 운전자가 백밀러를 보거나 운전자가 직접 뒤를 돌아보아 장애물과 중장비와의 거리를 인식하면서 작업하여야 하는데, 백밀러를 통해서 물체와의 거리를 감지하는 것은 중장비의 후방과 장애물과의 거리를 정확히 측정하지 못하여 중장비의 후방이 장애물과 접촉하는 사고가 빈번히 발생되고, 중장비의 차고는 비교적 높으므로 어린아이와 같은 높이가 낮은 장애물이 중장비의 후방에 근접하여 위치할 경우에는 중장비의 후미에 가려서 운전자가 장애물을 인식하기 어려우므로 접촉사고를 일으키는 문제점이 있었다.In general, when reversing heavy construction equipment such as wheel loaders, the driver should look at the rear-view mirror or the driver look back to recognize the obstacle and the distance between the heavy equipment to recognize the obstacle behind the heavy equipment. Detecting the distance of the heavy equipment does not accurately measure the distance between the rear of the heavy equipment and the obstacles, frequent accidents that the rear of the heavy equipment is in contact with the obstacle, and the height of the heavy equipment is relatively high, so low obstacles such as children are If it is located close to the rear, it is difficult to recognize the obstacle by the driver because it covers the rear of the heavy equipment has a problem causing contact accidents.
본 고안은 이와같은 문제점을 해결하기 위해 안출된 것으로서, 중장비의 후미에 초음파를 발생시키는 음파 발생부와, 상기 음파 발생부로부터 발생된 초음파가 장애물로부터 반사되어 수용되어지는 음파 수용부를 다수개 설치하고, 음파 발생부로부터 발생된 초음파가 음파 수용부까지 전달되는데 걸리는 시간으로부터 컨트롤러에서 중장비의 후미로부터 장애물까지의 거리를 계산하고 이와같이 계산된 거리가 일정범위내로 근접하게 될 경우에는 경고등이 발광되고 경보음이 울리도록 하여 운전자가 경각심을 가지도록 하고 있다.The present invention was devised to solve such a problem, and installs a plurality of sound wave generators for generating ultrasonic waves at the rear of heavy equipment, and a plurality of sound wave receivers in which ultrasonic waves generated from the sound wave generators are reflected from obstacles, From the time it takes for the ultrasonic wave generated from the sound wave generator to reach the sound wave receiving unit, the controller calculates the distance from the rear of the heavy equipment to the obstacle. When the calculated distance approaches the predetermined range, a warning light is emitted and an alarm sound sounds. It's ringing so the driver is alert.
따라서 본 고안은 운전자가 중장비를 후진할시에 장애물을 정확하게 인식할 수 있게 하므로 접촉사고를 예방할 수 있도록 하는데에 목적이 있는 것이다.Therefore, the present invention aims to prevent contact accidents by allowing the driver to correctly recognize obstacles when reversing heavy equipment.

첨부도면에 의해 본 고안을 상세히 설명하면 다음과 같다.Referring to the present invention in detail by the accompanying drawings as follows.
도1은 본 고안에 따른 장치가 중장비에 설치된 상태로 도시한 사용상태도이며, 도 2는 본 고안에 따른 장치의 블록도로서, 상기 도면에서 보면, 본 고안은 휠 로더와 같은 중장비의 후미에 초음파가 후방으로 발생되도록 설치되는 음파 발생부(1)와, 상기 음파 발생부(1)로 부터 발생된 초음파가 장애물로부터 반사되어 수용되도록 중장비의 후미에 상기 음파 발생부(1)와 함께 설치되는 음파 수용부(2)와, 상기 음파 발생부(1) 및 음파 수용부(2)로 부터의 신호가 입력되고 밧데리(4)로부터 전원이 공급되도록 연결된 컨트롤러(3)와, 상기 컨트롤러(3)로 부터의 출력신호가 전달되도록 컨트롤러(3)로 부터 연결된 1차 경고등(5), 2차 경고등(6) 및 경음기(7)로 구성된다.1 is a state diagram showing a state in which the device according to the present invention is installed in the heavy equipment, Figure 2 is a block diagram of the device according to the present invention, as seen in the drawing, the present invention is the ultrasonic wave at the rear of the heavy equipment such as a wheel loader A sound wave generator 1 installed to be generated rearward, and a sound wave receiver installed together with the sound wave generator 1 at the rear of the heavy equipment so that the ultrasonic waves generated from the sound wave generator 1 is reflected from the obstacle (2), and a controller (3) connected so that the signals from the sound wave generator (1) and the sound wave receiver (2) are input and powered from the battery (4), and from the controller (3). It consists of a primary warning light (5), a secondary warning light (6) and a horn (7) connected from the controller (3) so that the output signal is transmitted.
상기 컨트롤러(3)에서는 음파 발생부(1)로 부터 발생된 초음파가 장애물로부터 반사되어 음파 수용부(2)로 복귀하는데 걸리는 시간에 의해서, 중장비 후미로부터 장애물까지의 거리를 계산하는데 그 원리는 다음과 같다.The controller 3 calculates the distance from the rear of the heavy equipment to the obstacle by the time taken for the ultrasonic wave generated from the sound wave generator 1 to be reflected from the obstacle and returned to the sound wave receiver 2. Same as
중장비 후미로부터 장애물까지의 거리(D)=C×T/2Distance from heavy equipment rear to obstacles (D) = C × T / 2
단, C = 331 +0.6t 이며Where C = 331 + 0.6t
t는 기온,t is the temperature,
C는 초음파의 전달속도,C is the delivery rate of the ultrasound,
T는 초음파 음파 발생부를 떠나서 음파 수용부로 복귀는데 거리는 시간T is the time taken to leave the ultrasonic wave generator and return to the acoustic wave receiver.
이와같은 원리에 의해 계산되어진 D값에 의하여 컨트롤러(3)에서는 제3도에 도시된 바와 같이 1차 경고등(5), 2차 경고등(6) 및 경음기(7)가 작동되도록 하여서 운전자로 하여금 경각심을 가지도록 하고 있다.The D value calculated by this principle causes the driver 3 to operate the primary warning light 5, the secondary warning light 6 and the horn 7 as shown in FIG. To have.
중장비가 후진을 하다가 D값(중장비 후미로부터 장애물까지의 거리)이 1차 경계거리 이내로 진입하게 되면 상기 컨트롤러(3)에서의 1차 경고등(5)을 ON하는 신호를 출력하며, 중장비가 계속 후진하여 2차 경계거리안까지 진입하게 되면 상기 컨트롤러(3)에서 2차 경고등(6) 및 경음기(7)를 ON하는 신호를 출력하며, 운전자가 중장비를 1차 경계거리 밖으로 이동시키면 상기 컨트롤러(3)에서 1차 경고등(5), 2차 경고등(6) 및 경음기(7)를 OFF하는 신호를 출력하게 된다.When the heavy equipment reverses and the D value (distance from the heavy equipment tail to the obstacle) enters within the primary boundary distance, the controller outputs a signal to turn on the primary warning light (5) in the controller (3), and the heavy equipment continues to reverse. When the vehicle enters the secondary boundary distance, the controller 3 outputs a signal for turning on the secondary warning light 6 and the horn 7, and when the driver moves the heavy equipment out of the primary boundary distance, the controller 3. Outputs a signal to turn off the primary warning light (5), secondary warning light (6) and horn (7).
따라서 운전자는 중장비 후진시에 장애물에 대해 중장비가 접근한는 것을 단계적으로 인식할 수 있을 뿐만 아니라, 2차 경계거리 안까지 진입할 경우에는 경음기(7)까지 ON되므로 후진시 발생될 수 있는 충동사고를 완전히 예방할 수 있는 것이다.Therefore, the driver can not only recognize step by step heavy equipment approaching obstacles when reversing heavy machinery, but also turn on the horn 7 when entering into the second boundary distance, so that the driver can completely avoid impulse accidents that may occur when reversing. It can be prevented.
이와같이 본 고안은 중장비의 후미에 초음파를 발생시키는 음파 발생부와, 상기 음파 발생부로부터 발생된 초음파가 장애물로부터 반사되어 수용되어지는 음파 수용부를 다수개 설치하고, 음파 발생부로부터 발생된 초음파가 음파 수용부까지 전달되는데 걸리는 시간으로부터 컨트롤러에서 중장비의 후미로부터 장애물까지의 거리를 계산하고 이와같이 계산된 거리가 일정범위내로 근접하게 될 경우에는 경고등이 발광되고 경보음이 울리도록 하여 운전자가 경각심을 가지도록 하는 효과가 있으며, 이에따라 운전자가 장애물을 정확하게 인식할 수 있게 하므로 접촉사고를 예방할 수 있도록하는 효과가 있는 것이다.As such, the present invention provides a sound wave generator for generating ultrasonic waves at the rear of heavy equipment, and a plurality of sound wave receivers in which ultrasonic waves generated from the sound wave generator are reflected from obstacles, and the ultrasonic waves generated from the sound wave generator receive sound waves. The controller calculates the distance from the rear of the heavy equipment to the obstacle from the time it takes to reach the unit and if the calculated distance is close to a certain range, the warning light is emitted and the alarm sounds so that the driver is alert. There is an effect, and accordingly, the driver can recognize the obstacle accurately, so that it is possible to prevent contact accidents.
