The invention discloses an electrohydraulic control system of four-legged leveling platform. The electrohydraulic control system adopts a programmable logic controller (PLC) as a main control element,and comprises a computer; the computer is connected with a PLC module; the PLC module is connected with a digital output module; the digital output module is connected with an intermediate relay; theintermediate relay is connected with an electromagnetic valve; the electromagnetic valve is connected with a control console; the control console is connected with an electrohydraulic pressure switchand a sensor; the electrohydraulic pressure switch is connected with the PLC module through a digital input module; the sensor is connected with the computer through a controller area network (CAN) bus; and a double-axis sensor in a leveling system is installed at one corner of the platform, and the X axis and the Y axis are parallel to two faces of the platform respectively. According to the electrohydraulic control system, through optimization of software and hardware and change of a signal transmission mode, the anti-interference capability is enhanced.
