Description

암전류 측정장치{DARK CURRENT MEASURING APPARATUS}Dark Current Measuring Device {DARK CURRENT MEASURING APPARATUS}

본 발명은 암전류 측정장치에 관한 것으로, 보다 상세하게는 차량의 구비된 각 전장품의 측정 조건을 자동으로 설정하기 위한 암전류 측정장치에 관한 것이다.The present invention relates to a dark current measuring device, and more particularly to a dark current measuring device for automatically setting the measurement conditions of each of the electrical equipment provided in the vehicle.

일반적으로, 암전류(Dark Current)는 전력의 소모가 발생되지 않는 상황에서도 전원 발생부와 부하간에 전류의 도통로가 형성되어 있는 경우 연결되어 있는 부하나 선로를 통하여 흐르는 전류를 칭하는 것으로, 보다 상세하게는 시스템 오프(off)시 입력되는 신호에 대해 즉각적인 동작을 수행하기 위해 차량의 각 장치에 흐르는 전류를 칭한다.In general, dark current refers to a current flowing through a load or a line connected when a current conduction path is formed between a power generation unit and a load even in a situation where power consumption is not generated. Refers to the current flowing to each device of the vehicle to perform an immediate operation on a signal input when the system is off.

암전류가 차량에 과다하게 흐를 경우 배터리의 성능이나 각종 전장품의 기능에 영향을 주어 전장품의 고정이나 파손을 야기시킬 수 있으며, 이를 방지하기 위해 암전류 측정장치를 통해 차량의 각 전장품에 흐르는 암전류를 미리 측정하여 차량의 성능 향상을 향상시키고 있다.If the dark current flows excessively in the vehicle, it may affect the performance of the battery or the function of various electric appliances, which may cause the fixing or breakage of the electric component.In order to prevent this, the dark current flowing through each electric appliance of the vehicle is measured in advance. To improve the performance of the vehicle.

이러한 암전류 측정장치는 각 전장품에 따른 측정 조건에 따라 암전류를 측정해야 하기 때문에 작업자는 차량의 전원조건 변경, 도어 잠금 노트 상태 변경, 리모콘 조작, 도어 열기, 변속레버 위치변경 등의 설정 조건을 직접 조작하였으며, 이로 인해 조건 설정에 따른 측정 시간이 과다하게 소요되는 문제점이 발생된다.Since the dark current measuring device needs to measure the dark current according to the measurement conditions according to each electronic device, the operator directly manipulates the setting conditions such as changing the power condition of the vehicle, changing the state of the door lock note, operating the remote control, opening the door, and changing the shift lever position. This causes a problem that excessive measurement time is required according to the condition setting.

특히, 향후에는 이러한 측정 유닛트의 수가 증가되고 있기 때문에 측정 조건이 더욱 복잡해지고 이로 인해 과다한 측정시간 소요 및 그에 따른 작업자의 실수에 의한 측정 신뢰성이 저하되는 문제점이 발생된다.In particular, since the number of such measurement units is increasing in the future, the measurement conditions become more complicated, and thus, a problem arises in that the measurement reliability is reduced due to excessive measurement time and consequent operator error.

상기와 같은 문제점을 해결하기 위해, 본 발명은 암전류 측정 시간을 단축시키기 위한 암전류 측정장치를 제공하는 것을 그 목적으로 한다.In order to solve the above problems, an object of the present invention is to provide a dark current measuring device for reducing the dark current measurement time.

또한, 본 발명은 암전류 측정 신뢰도를 높이기 위한 암전류 측정장치를 제공하는 것을 또 다른 목적으로 한다.In addition, another object of the present invention is to provide a dark current measuring device for increasing the dark current measurement reliability.

상기 전원 입력부로부터 온 신호가 입력되면 동작신호 입력부는 B+, ACC, IGN1, IGN2 중 어느 하나가 선택 가능하도록 구성될 수 있다.When a signal from the power input unit is input, the operation signal input unit may be configured such that any one of B +, ACC, IGN1, and IGN2 is selectable.
