Abstract

본 발명은 조도 감별에 의한 리모콘 위치 감지회로에 관한것으로, 종래에는 사용자마다 표현할 수 잇는 입력음성신호의 레벨 및 주파수가 다르고, 보편성을 추구하기 위해서 검출범위의 폭을 넓게 두어야 함으로 에러발생이 크고, 또한 리모콘의 내부 직류전원이 유지되는 기간인에만 동작이 가능하므로 전력소모량이 많은 문제점이 있었다. 이러한 점을 감안하여 리모콘 위치 확인용 발신음 및 발과을 출력하기 위해 광 센서로 포토 트랜지스터를 사용하여 광량에 따라 트랜지스터의 출력 전압이 구분되며, 이를 2진화하여 메모리한 다음 기준레벨 이상의 조도 변화량이 검출되면 부저 및 LED를 발광할 수 있는 제어 전압을 출력함으로써, 조도 감별에 따른 선택적 전원사용으로 전력소모를 줄이고, 시계겸용 및 부저음과 함께 발광장치의 사용으로 실용성을 향상 시킬 수 있다.The present invention relates to a remote control position sensing circuit by discrimination of illuminance, conventionally, the level and frequency of the input voice signal that can be expressed by the user is different, the error occurrence is large because the width of the detection range should be wide in order to pursue universality, In addition, since the operation is possible only during the period of maintaining the internal DC power supply of the remote control, there was a problem of a large amount of power consumption. In consideration of this, the output voltage of the transistor is divided according to the quantity of light by using a photo transistor as an optical sensor to output a dial tone and an outgoing light for positioning the remote controller. By outputting a control voltage capable of emitting the buzzer and the LED, it is possible to reduce the power consumption by using a selective power supply according to the illumination discrimination, and improve the practicality by using a light emitting device together with a clock and a buzzer sound.
