상기한 본 발명의 목적과 특징 및 장점을 이해하기 쉽도록 이하 첨부도면을 참조하여 본 발명의 일 실시예에 대해 상세히 설명한다.DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings in order to facilitate understanding of the objects, features, and advantages of the present invention.
첨부도면 제1도는 본 발명에 따른 방법을 실시하기에 적합한 시험장치의 시스템 구성이 도시되어 있다.FIG. 1 shows a system configuration of a test apparatus suitable for implementing the method according to the present invention.
전파면역성 시험장치는 통상 사용자의 키 입력과 고주파 출력단에서 전력계(16)에 의해 검출된 전력신호를 입력받아 전계 칼리브레이션 및 측정을 수행하고 전계측정값을 모니터(20)에 디스플레이하는 컴퓨터(10)와, 이 컴퓨터의 제어라인에 연결되고 고주파신호를 발생하는 신호발생기(12)와, 신호발생기(12)의 고주파신호를 증폭하여 안테나(1)의 커플러로 공급하는 전력증폭기(14)와, 안테나에서 발생된 전계강도를 검출하는 프로브(21) 및 이 프로브의 검출전압을 컴퓨터(10)에 전달하는 모니터(20)로 구성된다.The radio wave immunity test apparatus typically receives a power signal detected by the power meter 16 at a key input of a user and a high frequency output terminal, performs computer calibration and measurement, and displays the electric field measurement value on the monitor 20; A signal generator 12 connected to the control line of the computer for generating a high frequency signal, a power amplifier 14 for amplifying the high frequency signal of the signal generator 12 and supplying it to the coupler of the antenna 1, A probe 21 for detecting the generated electric field strength and a monitor 20 for transmitting the detected voltage of the probe to the computer 10.
이와 같은 구성의 자동차 전파면역성 시험장치에서, 사용자가 안테나(1)에 전력을 기준 변수로 설정하고 차량이 없는 테스트 장소에서 특정한 테스트 레벨의 전계가 발생되도록 안테나(1)에 전력을 공급하여 전계 칼리브레이션 및 측정을 위한 준비를 하게 된다.In the radio wave immunity test apparatus having such a configuration, the user sets the power to the antenna 1 as a reference variable and supplies electric power to the antenna 1 so that an electric field of a specific test level is generated at a test site without a vehicle. And prepare for measurement.
이렇게 안테나(1)에 공급된 전력은 전력계(16)을 통해 컴퓨터(10)에 공급전력이 기록되고, 동시에 프로브(21)에 공급전력에 대한 전계강도 신호를 측정하여 모니터(20)에 보여주게 된다.The power supplied to the antenna 1 is recorded in the power supply to the computer 10 through the power meter 16, and at the same time to measure the electric field strength signal for the power supply to the probe 21 to show on the monitor 20 do.
이렇게 측정된 전계강도 신호는 교정후 프로브(21)를 차량으로부터 제거한 다음 실제 시험장소에 놓고 교정된 공급전력값으로 고주파를 차량에 인가하고, 이때의 전파면역성 평가를 수행한다.The measured electric field strength signal is removed from the vehicle after calibration, and then the probe 21 is placed in an actual test site, and a high frequency is applied to the vehicle as a calibrated supply power value, and then radio wave immunity evaluation is performed.
이때, 상기 전계강도 신호는 컴퓨터(20)의 제어를 받는 신호발생기(12)에서 발생된 신호가 증폭기(14)를 거쳐 커플러(15)에 제공되며, 이 전계강도 신호에 의해 교정이 이루어지게 된다.In this case, the electric field strength signal is a signal generated by the signal generator 12 under the control of the computer 20 is provided to the coupler 15 via the amplifier 14, the correction is made by the electric field strength signal. .
마지막으로, 교정된 공급값에 대한 고주파 인가로 평가된 전파면역성은 다시 전계강도 신호로 모니터(20)에 모니터링 되어 사용자가 쉽게 그 평가결과를 알 수 있게 된다.Finally, the radio wave immunity evaluated by applying high frequency to the calibrated supply value is again monitored by the electric field intensity signal on the monitor 20 so that the user can easily know the evaluation result.
