Abstract

본 발명은 자동차 외곽 운전석 일측에 설치된 원터치식 스위치 조작에 의해 주ㆍ정차시킨 차량의 운전자를 무선으로 호출할 수 있도록 한 차량이동 요청장치에 관한 것으로, 원터치식으로 조작 가능한 스위치(SW)를, 일정시간(예 : 2~5Sec)동안 펄스(예 : 200Hz)를 발생하는 코드 발생기(10)에 연결하고, 상기 코드 발생기(10)를 발생된 펄스를 고주파 신호로 변조하는 고주파 번조기(20)와 발진 변조된 신호를 증폭시키는 증폭부(30)를 통해 주파수 신호를 자유공간에 방사하는 안테나(ANT)에 연결하여 송신기를 구성하고, 자유공간으로부터 안테나(ANT)를 통해 입력받는 수신부(40)를, 수신된 신호를 기준치(예 : 250Hz)와 비교하여 적정 레벨로 맞추는 앰프(50)와 필요 신호만을 검출하고, 불필요한 잡음을 제거하는 신호 검출기(60)를 통해 경보음 또는 진동음을 울리는 경보기(70)에 연결되게 구성한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle movement request apparatus which allows a driver of a vehicle parked and stopped by a one-touch switch operation installed on one side of an automobile driver's seat to be wirelessly called. A high frequency frequency generator 20 which is connected to a code generator 10 generating a pulse (eg 200 Hz) for a time (eg 2 to 5 sec) and modulates the code generator 10 into a high frequency signal; The transmitter 30 is connected to an antenna ANT radiating a frequency signal in a free space through an amplification unit 30 for amplifying the oscillation modulated signal, and the receiver 40 receiving the antenna 40 from the free space is input through the antenna ANT. By comparing the received signal with a reference value (for example, 250 Hz), the amplifier 50 detects only an appropriate level and a necessary signal, and generates an alarm sound or a vibration sound through a signal detector 60 that removes unnecessary noise. It is configured to be connected to the view (70).

Claims

One-touch switch SW is connected to a code generator 10 that generates a pulse (for example, 200 Hz) for a predetermined time (for example, 2 to 5 sec), and the code generator 10 is connected to the generated pulse. The transmitter is configured by connecting a frequency signal to an antenna ANT that radiates a frequency signal in free space through a high frequency wave generator 20 for modulating a high frequency signal and an amplifier 30 for amplifying the oscillated modulated signal. The receiver 40 receiving the input signal through the ANT compares the received signal with a reference value (for example, 250 Hz) and detects only the amplifier 50 and a required signal, and a signal detector 60 for removing unnecessary noise. Vehicle moving request device, characterized in that configured to be connected to the alarm (70) to sound an alarm sound or vibration through.

The vehicle movement request apparatus according to claim 1, wherein the switch (SW) is provided at one side of the vehicle exterior.
