APPARATUS FOR CONTROLLING HYDRAULIC OR PNEUMATIC VALVE IS CAPABLE OF WIRE/WIRELESS CALIBRATION

摘要

The present invention relates to a hydraulic valve controller device. According to the present invention, the hydraulic valve controller device includes: a pressure sensing unit including a sensor used to detect the pressure of a hydraulic valve; an analog signal input unit receiving an analog control signal; a digital signal input unit receiving a digital control signal; a control unit which compares and calculates the pressure of the hydraulic valve detected in the pressure sensing unit and control signals input from the analog signal input unit and the digital signal input unit to control the hydraulic valve by generating the pulse width modulation (PWM) waves; a valve driving unit which controls the operation of the hydraulic valve according to the PWM waves generated in the control unit; and an output unit which outputs the pressure value of the hydraulic valve detected in the pressure sensing unit as a voltage or a current. According to the present invention, the hydraulic valve controller device can calibrate through wired or wireless communication and enable the user to perform the calibration operation, thereby increasing the user convenience.
