[종래의 문제점에 대한 기술적과제][Technical Challenges on Conventional Problems]
기존에는 차량주행중에 차량용속도계의 속도성능과 내구성시험을 테스트하기 위한 속도계시험장치를 구비하고 있지 못해 차량주행중에 모터의 속도를 정확히 제어하지 못하므로써 차량속도계의 속도성능 및 내구성시험을 정확히 테스트하지 못하는 등 문제점이 야기되었던 것이다.In the past, it was not equipped with a speedometer test device for testing the speed performance and durability test of the vehicle speedometer while driving the vehicle. Therefore, the speed performance and durability test of the vehicle speedometer cannot be accurately tested because the speed of the motor cannot be accurately controlled during the vehicle driving. Back problems were caused.

본 고안은 자동차용 속도계 시험장치에 관한 것으로, 특히 차량주행중에 차량용 속도계의 속도성능 및 내구성시험을 정확히 테스트할 수 있도록 하는 자동차용 속도계 시험장치에 관한 것이다.The present invention relates to a vehicle speedometer test apparatus, and more particularly to a vehicle speedometer test apparatus that can accurately test the speed performance and durability test of the vehicle speedometer while driving.
기존에는 본 고안과 같이 차량주행중에 차량용속도계의 속도성능과 내구성시험을 테스트하기위한 속도계시험장치를 구비하고 있지못해 차량주행중에 모터의 속도를 정확히 제어하지 못하므로써 차량속도계의 속도성능 및 내구성시험을 정확히 테스트하지 못하는등 문제점이 발생되었던 것이다.As the present invention does not have a speedometer test device for testing the speed performance and durability test of a vehicle speedometer while driving a vehicle, the speed performance and durability test of a vehicle speedometer can not be controlled by accurately controlling the speed of a motor while driving a vehicle. Problems occurred, such as incorrect testing.
본 고안은 상기와 같은 종래의 문제점을 해결하고자 이루어진 것으로서, 그 목적은 차량주행중에 차량용속도계의 속도성능 및 내구성시험을 정확히 테스트 할 수 있도록 하는데 있다. 좀 더 상세하게는 가변저항기의 조절에 의하여 모터의 회전수량이 변화되면 모터의 회전수가 펄스센서의 회전수와 동일하게되어 카운터로 부터 센서에서 발생되는 펄스를 카운트하여 속도로 환산제어하므로 모터의 속도를 정확히 제어해 주므로써 차량용속도계의 속도성능 및 내구성시험을 정확히 테스트할 수 있게 한 것이다.The present invention is made to solve the conventional problems as described above, the purpose is to be able to accurately test the speed performance and durability test of the vehicle speedometer while driving the vehicle. More specifically, if the rotational speed of the motor is changed by the control of the variable resistor, the rotational speed of the motor is the same as the rotational speed of the pulse sensor. By precisely controlling the speed, the speed performance and durability test of the vehicle speedometer can be accurately tested.
이를 첨부도면에 따라 본 고안을 상세히 설명하면 다음과 같다.Referring to the present invention in detail according to the accompanying drawings as follows.
제1도는 자동차용속도계의 속도성능 및 내구성시험을 위한 본 고안의 블럭구성도로서, 제1도의 구성에서와 같이 AC전원을 공급하기 위한 전원스위치(SW)와 구동모터의 내구시험시간을 제어하는 타임제어기(10)와 구동모터의 회전수를 자동혹은 수동으로 조절하는 가변저항기(VR)와 구동모터의 회전수를 펄스로 측정하는 펄스센서(30)와 펄스센서에서 발생되는 펄스수를 카운트하여 속도로 환산제어하는 카운터(40)와 차량속도계의 속도성능을 측정 또는 기록하는 속도계(50)와 속도계의 속도에 따라 구동하는 릴레이(RY)와 속도성능에 따라 점등되는 램프(LAMP1),(LAMP2),(LAMP3)로 각각 구성되어 있다.1 is a block diagram of the present invention for the speed performance and durability test of the speedometer for automobiles, as shown in the configuration of FIG. 1 to control the endurance test time of the power switch (SW) and the drive motor for supplying AC power By counting the number of pulses generated from the pulse sensor 30 and the pulse sensor 30 to measure the rotational speed of the drive motor and the variable resistor (VR) to automatically or manually adjust the rotational speed of the time controller 10 and the drive motor Counter 40 for converting and controlling the speed, speedometer 50 for measuring or recording the speed performance of the vehicle speedometer, relay RY driven according to the speed of the speedometer, and lamps lit according to the speed performance LAMP 1 , ( LAMP 2 ) and (LAMP 3 ), respectively.
따라서 제2a도는 주행속도계를 최고눈금의 50% 에서 80% 범위내에서 아래의 사이클로 20만㎞주행후 지침의 흔들림과 지시오차 및 각부의 이상유무테스트를 그래프로 나타낸 것이고, b는 지시오차에 대한 시험결과치이고, c는 시험항목 및 시험내용, d는 지침흔들림 시험도표, e는 내구시험후 지시오차 도표를 각각 나타낸 것이다.Therefore, Figure 2a is a graph showing the shaking and indicating error of each guideline and the test for abnormality of each part after driving the speedometer in the range of 50% to 80% of the maximum scale with the following cycle. C is a test result and test content, d is a guideline shaking test chart, and e is an indication of an error chart after the endurance test.
이와같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above are as follows.
먼저 전원스위치(SW)를 온(ON)시키면 AC전원은 전원스위치를 통해 타임조절기(10)에 인가되어 타임제어기(10)로 부터 구동모터(20)의 내구시험시간을 제어한다.First, when the power switch (SW) is turned on (ON), the AC power is applied to the time controller 10 through the power switch to control the endurance test time of the drive motor 20 from the time controller 10.
이런 상태에서 가변저항기(VR)의 구동모터의 회전수를 조절하면 구동모터(20)의 회전수 량이 변화된다.In this state, when the rotation speed of the drive motor of the variable resistor VR is adjusted, the rotation speed of the drive motor 20 is changed.
이렇게 구동모터의 회전수 량이 변화됨에 따라 구동모터(20)의 회전수가 펄스센서(30)의 회전수와 동일하게 되어 센서(30)에서 발생되는 펄스를 카운터(40)에서 카운트하게 되고 카운트한 펄스를 속도로 환산제어하여 속도계(50)의 속도를 상승시킨다.As the rotational speed of the driving motor is changed, the rotational speed of the driving motor 20 becomes the same as the rotational speed of the pulse sensor 30, so that the pulse generated by the sensor 30 is counted by the counter 40, and the counted pulse By controlling the speed to increase the speed of the speedometer 50.
이렇게 속도계(50)의 속도상승에 따라 릴레이(RY)가 구동되어 외부램프(LAMP), (LAMP2), (LAMP3)등이 속도계의 속도에 따라 점등되어 속도계의 속도성능 및 속도계의 내부램프의 점등상태를 확인하므로써 차량용속도계의 속도성능 및 내구성시험을 정확히 테스트하게 되는 것이다.As the speed of the speedometer 50 increases, the relay RY is driven so that the external lamps LAMP, LAMP 2 , and LAMP 3 light up according to the speed of the speedometer, and thus the speed performance of the speedometer and the internal lamp of the speedometer. By checking the lighting condition of the vehicle, the speed performance and durability test of the vehicle speedometer is accurately tested.
이상과 같이 본 고안은 차량주행중에 모터의 속도를 정확하게 제어해 주므로써 차량용속도계의 속도성능과 내구성시험을 정확히 테스트할 수 있는 효과가 있다.As described above, the present invention precisely controls the speed of the motor while driving the vehicle, thereby effectively testing the speed performance and durability test of the vehicle speedometer.
