According to the characteristics of hydraulic support intelligent control, the hydraulic support control system is designed and analyzed based on Controller Area Network (CAN) technology. Through the characteristics of CAN-bus network communication, the host computer communication and monitoring requirements is researched, and the mission of function is established. The data transmission program is designed under MSComm ActiveX which accomplishes stable communication function. Based on hydraulic test bench, the reliability of data transmission is verified which provides some guidance for the development of the intelligent control.
