Description

비례밸브 구동장치Proportional valve drive

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 발명의 일실시예에 의한 비례밸브 구동장치의 전기회로도,1 is an electrical circuit diagram of a proportional valve driving apparatus according to an embodiment of the present invention,

제2도는 그 비례밸브 제어장치에 있어서의 적분신호와 과전압 제한회로의 출력과의 관계를 나타낸 그래프.2 is a graph showing the relationship between the integral signal and the output of the overvoltage limiting circuit in the proportional valve control device.

Claims (1)

제어단자를 가지는 전자스위치와 비례밸브의 코일을 전원 회로에 직렬로 접속한 비례밸브 회로나, 상기 비례밸브의 코일을 흐르는 전류를 검출하는 전류검출회로와, 그 전류 검출회로와 마이크로 컴퓨터와의 사이에 접속되는 과전압 제한회로를 구비하구 상기 마이크로 컴퓨터는, 목표치 신호에 의거하여 변조된 펄스 변조신호를, 상기 제어단자에 송출하여 상기 전자 스위치를 구동하는 구동수단과, 상기 과전압 제한회로를 거친, 상기 전류 검출회로의 출력에 의거하여, 상기 목표치 신호를 보정하는 보정수단과, 소정치 이상의 상기 출력을 검출하면, 상기 펄스 변조신호의 송출을 정지 유지하는 유지수단을 가지는 것을 특징으로 하는 비례밸브 구동장치.A proportional valve circuit in which an electronic switch having a control terminal and a coil of a proportional valve are connected in series with a power supply circuit, a current detecting circuit for detecting a current flowing through a coil of the proportional valve, and between the current detecting circuit and a microcomputer. And an overvoltage limiting circuit connected to the microcomputer, wherein the microcomputer passes the pulse modulation signal modulated on the basis of a target value signal to the control terminal to drive the electronic switch, and passes through the overvoltage limiting circuit. And a correction means for correcting the target value signal based on the output of the current detection circuit, and a holding means for stopping the transmission of the pulse modulated signal when the output of the predetermined value or more is detected. . ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
