Claims (1)
송신기(1)에서 송출되는 소정 주파수의 고주파 전력을 안테나(2)로부터 방사하여 그 방사영역내에 전기한 주파수에 동조되고, 또 그 주파수에 의해 정수배 높은 주파수로 체배하여 다시 송신하는 주파수센서(3)를 배치하여 그 센서(3)로 부터 방사되는 전파를 수신 안테나(4)로 수신하여 수신기(5)에 공급하고, 그 전파의 유무를 수신기(5)의 출력에서 검충하여 전기한 센서(3)가 전기한 방사영역내에 존재하고 있는가의 여부를 판단하도록 하는 것을 특징으로 하는 센서 검지방법.Frequency sensor 3 that radiates high frequency power of a predetermined frequency transmitted from transmitter 1 from antenna 2, is tuned to a frequency transmitted in the radiation region, and multiplied by an integer multiple of that frequency and then transmitted again 3 is arranged to receive the radio wave radiated from the sensor 3 by the receiving antenna 4 and supply it to the receiver 5, and the presence or absence of the radio wave at the output of the receiver 5 and the sensor (3) And judging whether or not is present in the radiated region described above.※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
Data transmission system with measured values modulating IR beam - has receiver with two sensitive elements to distinguish between information and interference signals
