Abstract

본 발명은 자동차 배터리(BATTERY)의 방전을 방지하기 위한 경보장치에 관한 것으로, 특히 키 스위치에 키가 삽입되어 있는지의 여부를 지속적으로 검출하는 키검출부(10)와; 배터리 전원 출력선(미도시)의 어느 일측 선로에 부착되어 사용전류의 양을 검출하는 전류검출부(20)와; 소정의 제어신호에 의해 점등되어, 키가 키 스위치에 이탈된 상태에서 소정의 값 이상의 전류가 소모되고 있음을 시각적으로 나타내는 시각표시부(40)와; 소정의 제어신호에 의해 작동되어, 키가 키 스위치에서 이탈된 상태에서 소정의 값 이상의 전류가 소모되고 있음을 청각적으로 나타내는 청각표시부(50)와; 상기 키검출부(10)와 전류검출부(20)의 신호출력단과, 상기 시각 표시부(40)와 청각표시부(50)의 제어신호입력단 사이에 접속되어, 상기 키검출부(10)에서 인가되는 신호에 의해 자동차 키가 키 스위치에서 삽입되어 있는지의 여부를 검출하며, 상기 전류검출부(20)에 의해 전류의 소모정도를 검출하여, 키가 키 스위치에서 이탈된 상태에서 소정의 값 이상의 전류가 소모되고 있을 시, 이를 나타내는 소정의 제어신호를 상기 시각표시부(40)와 청각표시부(50)에 인가하는 마이컴(30)을 포함하여 구성됨을 특징으로 하는 자동차 배터리 방전 경보장치와 키검출부(10)를 이용하여 자동차 키가 키 스위치에 삽입되어 있는지의 여부를 지속적으로 검출하는 키검출단계(100)와; 상기 키검출단계(100)를 수행한 결과, 키가 2키 스위치에 삽입되어 있지 않는 것으로 판단됨에 따라, 전류검출부(20)를 이용하여 전류가 소모되고 있는지의 여부를 검출한 후, 전류가 소모되고 있을 경우에는 전류의 소비량이 소정의 값 이상인지의 여부를 검출하는 전류검출단계(200)와; 상기 전류검출단계(200)를 수행한 결과, 전류가 소정의 값 이상으로 소모되고 있는 것으로 판단됨에 따라, 상기 시각표시부(40)와 청각표시부(50)를 통해, 키가 키 스위치에서 이탈된 상태에서 소정의 값 이상의 전류가 소모되고 있음을 나타내는 소정의 경보신호를 발생하는 경보신호발생단계(300)를 포함하여 구성됨을 특징으로 하는 자동차 배터리 방전 경보장치의 제어방법이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an alarm device for preventing the discharge of an automotive battery, and more particularly to an alarm device for continuously detecting whether or not a key is inserted into a key switch. A current detector 20 attached to a line of a battery power output line (not shown) for detecting the amount of current to be used; A time display section (40) which is illuminated by a predetermined control signal and visually indicates that a current of a predetermined value or more is consumed in a state where the key is released from the key switch; An auditory display unit (50) operated by a predetermined control signal to audibly indicate that a current of a predetermined value or more is consumed in a state where the key is detached from the key switch; A signal output terminal of the key detection unit 10 and the current detection unit 20 is connected between the time display unit 40 and the control signal input terminal of the audible display unit 50. By the signal applied from the key detection unit 10 Detects whether or not a vehicle key is inserted in the key switch, detects the degree of consumption of the current by the current detecting unit (20), and when a current of a predetermined value or more is consumed while the key is detached from the key switch And a microcomputer 30 for applying a predetermined control signal indicative thereof to the time display unit 40 and the audible display unit 50. The automobile battery discharge alarm apparatus and the key detection unit 10 A key detecting step (100) for continuously detecting whether or not a key is inserted in the key switch; As a result of performing the key detection step 100, it is determined that the key is not inserted in the 2-key switch. After detecting whether the current is consumed by using the current detection unit 20, A current detection step (200) for detecting whether or not the consumption amount of the current is equal to or greater than a predetermined value; As a result of the current detection step 200, it is determined that the current is consumed to a predetermined value or more, the state in which the key is released from the key switch through the time display unit 40 and the auditory display unit 50 And an alarm signal generating step (300) for generating a predetermined alarm signal indicating that a current equal to or greater than a predetermined value is being consumed in the automobile battery discharge alarm device.

Claims

A key detecting unit for continuously detecting whether or not a key is inserted into the key switch; A current detecting unit attached to a line of a battery power output line for detecting an amount of current to be used; A time display section which is illuminated by a predetermined control signal and visually indicates that a current of a predetermined value or more is consumed in a state where the key is released from the key switch; An auditory display unit which is operated by a predetermined control signal to audibly indicate that a current of a predetermined value or more is consumed in a state where the key is detached from the key switch; A signal output terminal of the key detection unit and the current detection unit and a control signal input terminal of the time display unit and the auditory display unit to detect whether or not the vehicle key is inserted into the key switch by a signal applied from the key detection unit, A microcomputer for detecting a consumption level of the current by the current detector and applying a predetermined control signal to the time display unit and the auditory display unit when a current of a predetermined value or more is consumed in a state where the key is deviated from the key switch, And an alarming unit for detecting a discharge of the battery.

A key detecting step of continuously detecting whether or not a vehicle key is inserted into a key switch using a key code output unit; As a result of performing the key detection step, it is determined that the key is not inserted in the kiss position, and it is detected whether the current is consumed by using the current detection unit. If the current is consumed, A current detection step of detecting whether or not the current value is equal to or larger than a predetermined value; As a result of performing the current detection step, it is determined that the current is consumed in excess of the predetermined value, so that a current of a predetermined value or more is consumed in the state where the key is separated from the key switch through the time display unit and the auditory display unit And generating an alarm signal indicative of the presence of the alarm signal.
