Abstract
본 발명은 송수화기가 전화기로부터 내려져도 외부로부터 입력되는 주파수 레벨을 검출하여 일정한 시간이 지나면 수신이 가능하도록 한 전화기용 후크 스위치 제어회로에 관한 것으로써, 종래의 전화기는 사용자의 부주의나 실수로 인하여 송수화기가 전화기로부터 내려져 있을 경우 외부로부터 다른 사용자가 통화를 하려고 다이얼을 돌려도 송수화기가 내려져 있는 전화기에서는 수신이 불가능하기 때문에 사용자는 송수화기가 잘못놓인 상태를 발견해서 직접 송수화기를 전화기에 올려놓아 후크 스위치를 오프시켜야 할 수 밖에 없는 문제점이 발생하였다.The present invention relates to a hook switch control circuit for a telephone that detects a frequency level input from the outside even when the handset is lowered from the telephone, so that reception is possible after a predetermined time. Is off the phone, but the user cannot detect the handset and put the handset on the phone to turn off the hook switch. There was a problem that can only be done.
따라서 본 발명은 이러한 종래 기술의 문제점을 해소하기 위하여 전화기용 후크 스위치 제어회로에 있어서, 상기 후크 스위치가 온된 후 외부로부터 입력되는 주파수 레벨을 검출하는 레벨 검출부와, 상기 거출된 주파수 레벨 데이타를 저장시키거나 솔레노이드의 구동 및 부저의 구동을 제어하는 제어부와, 상기 제어에 의하여 검출된 주파수 레벨 데이타를 저장하는 데이타 저장부와, 상기 제어에 의해 후크 스위치를 오프시키는 솔레노이드 구동부와, 상기 제어에 의해 경보 신호를 발생시키는 부저 구동부로 구성하고, 전화기 자체에서 통화상태와 통화를 하고 있지 않은 상태를 판단하여 통화를 하고 있을 때는 정상적인 통화 상태을 계속 유지하고, 통화를 하고 있지 않은 상태에는 강제로 후크 스이치를 오프하여 송수화기가 전화기 본체에 올여 있는 것과 같은 입력대기상태로 만들어 사용자에게 편이를 제공하도록 한 것이다.Accordingly, the present invention provides a hook switch control circuit for a telephone in order to solve such a problem of the prior art, comprising: a level detector for detecting a frequency level input from the outside after the hook switch is turned on, and storing the extracted frequency level data; Or a control unit for controlling driving of the solenoid and driving of the buzzer, a data storage unit for storing the frequency level data detected by the control, a solenoid driving unit for turning off the hook switch by the control, and an alarm signal by the control It consists of a buzzer driving unit that generates a, and the phone itself judges the state of the call and the state of non-call and maintains the normal call state when the call is made, and the hook switch is forcibly turned off when the call is not made. Your handset Made with the input wait state as one that will provide convenience to the user.
