Research On Digitized Management And Control Of Electro-hvdraulic Proportional System Based On CAN Bus

As the electro-hydraulic proportional system developing to the direction of digitalization and intellectualization, digitized network control is becoming a new direction of development of the electro-hydraulic proportional control system.Research on digitized management and control for electro-hydraulic system based on CAN Bus is the combination of CAN bus network communication technology and electro-hydraulic proportional control technology, in order to achieve the digitalization, intellectualization and network management and control for electro-hydraulic proportional system. In this system control valves and sensors are connected to the CAN Bus via the CAN controller, to achieve the combination of traditional hydraulic valves and digitized electro-hydraulic proportional system.This research is based on a laboratory project "Integrated Hydraulic Power System" Designed electro-hydraulic proportional control system based on CAN bus. The system consists of the IPC, PC-CAN card, CAN Controllers. IPC, they form the core of the experimental control system. CAN controllers are located near the devices, and connect with them through I/O port.
