Claims (3)

  1. 이동체에 설치되어 주행방향에 따라 선택적인 주파수를 송신하고 특정주파수에 동조되어 무인차 제어신호를 발생하는 이동체용 교통 센서유니트와, 이동체의 주행경로상에 설치되어 이동체가 송신하는 주파수를 수신하여 선택된 주파수에 대응하는 출력신호를 상위제어 판단부로 인가하여 상위제어 판단부의 제어에 의해 지정된 주파수를 이동체로 송신하는 교통 통제용 센서 유니트를 포함하여 구성되는 것을 특징으로 하는 무인반송차의 교통 통제용 센서 유니트.
  2. 제1항에 있어서, 이동체용 교통 센서 유니트는 수신 신호를 멀티패스 필터(OP8)와 저역통과 필터(OP9)를 통과시켜 정류 및 평활하고 전압 비교기(OP10)를 통하여 그 출력 신호를 광결합소자(PC2)를 통하여 출력하고, 송신신호는 디코더(DEC)에 의해 버퍼(B1-B3)를 동작시키므로서 선택된 주파수 발생기(21-23)의 출력신호를 증폭기(OP7)를 통하여 출력하도록 구성하는 것을 특징으로 하는 무인반송차의 교통 통제용 센서 유니트.
  3. 제1항에 있어서, 주행로상에 설치되는 교통 통제용 센서 유니트는 송신신호를 발진회로(OP1,OP2)로 부터 릴레이(RY)스위치를 개재하여 증폭기(OP3)를 통하여 출력하고, 수신 신호는 복수로 병렬 구성된 필터 및 레벨검출부(11-14)중의 하나를 통하여 출력함과 동시에, 상기 필터 및 레벨검출부(11-14)의 출력신호와 상기 제어 판단부와 연결된 입출력 단자로 부터의 입력신호를 논리게이트를 통하여 상기 릴레이(RY)를 제어하도록 연결 구성하는 것을 특징으로 하는 무인반송차의 교통 통제용 센서 유니트.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
