As shown in FIG. 1, the solenoid valve 20 opens and closes according to a predetermined signal to adjust the flow of hydraulic pressure, the solenoid valve driving means 30 driving the solenoid valve 20, and the solenoid valve 20. Motion detection unit 40 for detecting a data signal related to the operating state of the, read the signal input by the user to check the operation state of the solenoid valve 20, and generates a duty control signal corresponding to the input signal Control means 10 for outputting to the solenoid drive means (30).

상기 제어수단(10)은 사용자에 의해 데이터를 입력을 받기 위한 입력부(11), 상기 입력부(11)를 통해 입력된 데이터를 판독하고, 상기 데이터를 솔레노이드 밸브(20)를 제어하기 위한 듀티 제어신호로 변환하여 해당 장치로 출력하는 제어부(12), 상기 제어부(12)에서 입력되는 신호를 소정의 출력신호로 변환하며, 상기 동작검출부(40)에서 입력되는 신호를 소정의 입력신호로 변환하는 변환부(13), 상기 제어부(12)와 솔레노이드 구동수단(30)간에 데이터 통신이 이루어지도록 하는 인터페이스부(14) 및 사용자가 모니터링 할 수 있도록 상기 인터페이스부(14)를 통해 상기 동작검출부(40)에서 검출된 데이터신호를 입력받아 표시하기 위한 표시부(15)를 포함한다.The control means 10 reads the input unit 11 for receiving data by the user, the data input through the input unit 11, and the duty control signal for controlling the solenoid valve 20.
