Abstract

이 발명은 자동차 도어의 개폐를 운전자가 파악할 수 있는 도어 열림 경보장치에 관한 것이다. 이 발명의 구성은, 1단입력신호를 수신하는 제1스위치, 2단입력신호를 수신하는 제2스위치, 제1스위치와 연결된 제1인버터, 제2스위치와 연결된 제3인버터, 제1인버터의 출력을 수신하는 제2인버터, 제2인버터의 출력을 수신하고, 제3인버터의 출력을 수신하여, 이를 논리곱하여 출력하는 제1논리곱회로, 제1인버터의 출력을 수신하고, 제3인버터의 출력을 수신하여, 이를 논리곱하여 출력하는 제2논리곱회로, 제1인버터의 출력을 수신하고, 제3인버터의 출력을 수신하여, 이를 논리합하여 출력하는 논리합회로, 제1논리곱회로의 출력을 수신하여, 그값이 하이논리값이면 온이되는 제1스프링스위치, 제2논리곱회로의 출력을 수신하여, 그 값이 하이논리값이면 온이 되는 제2스프링스위치, 논리합회로의 출력을 수신하여, 그 값이 하이논리값이면 점등되는 램프로 이루어진다. 이 발명의 효과는, 접촉식은 스프링의 작동이 불량해도 정상작동이 가능하고, 1단잠김, 2단잠김, 완전개폐를 구분하여 운전자가 파악할 수 있느 도어 열림 경보장치를 제공할 수 있다.The present invention relates to a door open alarm that allows the driver to grasp the opening and closing of the car door. The configuration of the present invention, the first switch for receiving the first stage input signal, the second switch for receiving the second stage input signal, the first inverter connected to the first switch, the third inverter connected to the second switch, the first inverter Receiving the output of the second inverter, the output of the second inverter, receiving the output of the third inverter, and output the result of the first logical circuit, the logical output and the output of the first inverter, the output of the first inverter, A second logical multiplication circuit for receiving the output, and logically multiplying the output, and receiving the output of the first inverter, receiving the output of the third inverter, and outputting the logical sum circuit for outputting the logical sum and outputting the output of the first logical output circuit. Receiving the output of the first spring switch and the second logical circuit which are turned on if the value is a high logic value, and receiving the output of the second spring switch and the logic circuit which are turned on if the value is a high logic value. If the value is high logical value, it turns on RAM It consists of. The effect of the present invention is that the contact type can be operated normally even if the operation of the spring is poor, it is possible to provide a door opening alarm device that can be grasped by the driver by distinguishing the first stage locking, the second stage locking, and the complete opening and closing.
